DETAILED DESCRIPTION

Various aspects relate generally to wireless communication and more particularly to full duplex (FD) communication. Some aspects more specifically relate to rules and/or signaling used to enable uplink transmission repetition across FD sets of symbols and non-FD sets of symbols. In some examples, a network node may configure a user equipment (UE) with multiple groups of sounding reference signal (SRS) resources, with a first group of SRS resources being associated with FD sets of symbols and a second group of SRS resources being associated with non-FD sets of symbols. In some aspects, the network node may configure the UE with two SRS resource sets, with a first SRS resource set corresponding to the FD set of symbols and the second SRS resource set corresponding to the non-FD set of symbols. In some other aspects, the network node may configure the UE with a single SRS resource set, with a first group of SRS resources of the SRS resource set being associated with the FD set of symbols and a second group of SRS resources of the SRS resource set being associated with the non-FD set of symbols. The network node may signal, to the UE, which groups of SRS resources are associated with an uplink transmission repetition (e.g., a physical uplink shared channel (PUSCH) repetition or a physical uplink control channel (PUCCH) repetition), such as by signaling a codepoint in a radio resource control (RRC) communication and/or a downlink control information (DCI) communication. Based at least in part on the signaling, the UE may identify whether the uplink transmission repetition is to span repetition occasions in the FD set of symbols and the non-FD set of symbols, or whether the uplink transmission repetition is to be transmitted in only the FD set of symbols or only the non-FD set of symbols.

Particular aspects of the subject matter described in this disclosure can implemented to realize one or more of the following potential advantages. In some examples, by enabling signaling of SRS resources to be used for an uplink transmission repetition across FD and non-FD sets of symbols, the described techniques can be used to flexibly configure a UE to perform uplink transmission repetitions across FD sets of symbols or not across FD sets of symbols according to channel conditions, network congestion, or other variables, thereby resulting in more efficient allocation of network resources. Moreover, by enabling signaling of SRS resources to be used for an uplink transmission repetition across FD and non-FD sets of symbols, the described techniques can be used to improve uplink coverage, improve uplink latency, and reduce communication errors between a network node and a UE for FD communication modes, thereby reducing power, computing, and network resource consumption that may otherwise be required to correct communication errors.

In some aspects, the UE120may include a communication manager140. As described in more detail elsewhere herein, the communication manager140may receive configuration information that configures one or more SRS resource sets, the one or more SRS resource sets including one or more SRS resources associated with an FD set of symbols and one or more SRS resources associated with a non-FD set of symbols; transmit a first SRS using the one or more SRS resources associated with the FD set of symbols and a second SRS using the one or more SRS resources associated with the non-FD set of symbols; receive at least one of an RRC communication or a DCI communication indicating at least one of the one or more SRS resources associated with the FD set of symbols or the one or more SRS resources associated with the non-FD set of symbols that are to be used for an uplink transmission repetition; and transmit, based at least in part on the at least one of the RRC communication or the DCI communication, the uplink transmission repetition in one of: only the FD set of symbols, only the non-FD set of symbols, or both the FD set of symbols and the non-FD set of symbols. Additionally, or alternatively, the communication manager140may perform one or more other operations described herein.

In some aspects, the network node110may include a communication manager150. As described in more detail elsewhere herein, the communication manager150may transmit, to a UE, configuration information that configures one or more SRS resource sets, the one or more SRS resource sets including one or more SRS resources associated with an FD set of symbols and one or more SRS resources associated with a non-FD set of symbols; receive, from the UE, a first SRS using the one or more SRS resources associated with the FD set of symbols and a second SRS using the one or more SRS resources associated with the non-FD set of symbols; transmit, to the UE, at least one of an RRC communication or a DCI communication indicating at least one of the one or more SRS resources associated with the FD set of symbols or the one or more SRS resources associated with the non-FD set of symbols that are to be used for an uplink transmission repetition; and receive, from the UE and based at least in part on the at least one of the RRC communication or the DCI communication, the uplink transmission repetition in one of: only the FD set of symbols, only the non-FD set of symbols, or both the FD set of symbols and the non-FD set of symbols. Additionally, or alternatively, the communication manager150may perform one or more other operations described herein.

In some aspects, the UE120includes means for receiving configuration information that configures one or more SRS resource sets, the one or more SRS resource sets including one or more SRS resources associated with an FD set of symbols and one or more SRS resources associated with a non-FD set of symbols; means for transmitting a first SRS using the one or more SRS resources associated with the FD set of symbols and a second SRS using the one or more SRS resources associated with the non-FD set of symbols; means for receiving at least one of an RRC communication or a DCI communication indicating at least one of the one or more SRS resources associated with the FD set of symbols or the one or more SRS resources associated with the non-FD set of symbols that are to be used for an uplink transmission repetition; and/or means for transmitting, based at least in part on the at least one of the RRC communication or the DCI communication, the uplink transmission repetition in one of: only the FD set of symbols, only the non-FD set of symbols, or both the FD set of symbols and the non-FD set of symbols.

FIG.4is a diagram illustrating an example400of SRS resource sets, in accordance with the present disclosure.

A UE120may be configured with one or more SRS resource sets to allocate resources for SRS transmissions by the UE120. For example, a configuration for SRS resource sets may be indicated in an RRC message (e.g., an RRC configuration message or an RRC reconfiguration message). As shown by reference number405, an SRS resource set may include one or more resources (e.g., shown as SRS resources), which may include time resources and/or frequency resources (e.g., a slot, a symbol, a resource block, and/or a periodicity for the time resources).

As shown by reference number410, an SRS resource may include one or more antenna ports on which an SRS is to be transmitted (e.g., in a time-frequency resource). Thus, a configuration for an SRS resource set may indicate one or more time-frequency resources in which an SRS is to be transmitted and may indicate one or more antenna ports on which the SRS is to be transmitted in those time-frequency resources. In some aspects, the configuration for an SRS resource set may indicate a use case (e.g., in an SRS-SetUse information element) for the SRS resource set. For example, an SRS resource set may have a use case of antenna switching, codebook, non-codebook, or beam management.

An antenna switching SRS resource set may be used to indicate downlink channel state information (CSI) with reciprocity between an uplink and downlink channel. For example, when there is reciprocity between an uplink channel and a downlink channel, a network node110may use an antenna switching SRS (e.g., an SRS transmitted using a resource of an antenna switching SRS resource set) to acquire downlink CSI (e.g., to determine a downlink precoder to be used to communicate with the UE120).

A codebook SRS resource set may be used to indicate uplink CSI when a network node110indicates an uplink precoder to the UE120. For example, when the network node110is configured to indicate an uplink precoder to the UE120(e.g., using a precoder codebook), the network node110may use a codebook SRS (e.g., an SRS transmitted using a resource of a codebook SRS resource set) to acquire uplink CSI (e.g., to determine an uplink precoder to be indicated to the UE120and used by the UE120to communicate with the network node110). In some aspects, virtual ports (e.g., a combination of two or more antenna ports) with a maximum transmit power may be supported at least for a codebook SRS.

A non-codebook SRS resource set may be used to indicate uplink CSI when the UE120selects an uplink precoder (e.g., instead of the network node110indicated an uplink precoder to be used by the UE120). For example, when the UE120is configured to select an uplink precoder, the network node110may use a non-codebook SRS (e.g., an SRS transmitted using a resource of a non-codebook SRS resource set) to acquire uplink CSI. In this case, the non-codebook SRS may be precoded using a precoder selected by the UE120(e.g., which may be indicated to the network node110).

A beam management SRS resource set may be used for indicating CSI for millimeter wave communications.

An SRS resource can be configured as periodic, semi-persistent (sometimes referred to as semi-persistent scheduling (SPS)), or aperiodic. A periodic SRS resource may be configured via a configuration message that indicates a periodicity of the SRS resource (e.g., a slot-level periodicity, where the SRS resources occurs every Y slots) and a slot offset. In some cases, a periodic SRS resource may always be activated, and may not be dynamically activated or deactivated. A semi-persistent SRS resource may also be configured via a configuration message that indicates a periodicity and a slot offset for the semi-persistent SRS resource, and may be dynamically activated and deactivated (e.g., using DCI or a MAC control element (MAC-CE)). An aperiodic SRS resource may be triggered dynamically, such as via DCI (e.g., UE-specific DCI or group common DCI) or a MAC-CE.

In some aspects, the UE120may be configured with a mapping between SRS ports (e.g., antenna ports) and corresponding SRS resources. The UE120may transmit an SRS on a particular SRS resource using an SRS port indicated in the configuration. In some aspects, an SRS resource may span N adjacent symbols within a slot (e.g., where N equals 1, 2, or 4). The UE120may be configured with X SRS ports (e.g., where X≤4). In some aspects, each of the X SRS ports may mapped to a corresponding symbol of the SRS resource and used for transmission of an SRS in that symbol.

As shown inFIG.4, in some aspects, different SRS resource sets indicated to the UE120(e.g., having different use cases) may overlap (e.g., in time and/or in frequency, such as in the same slot). For example, as shown by reference number415, a first SRS resource set (e.g., shown as SRS Resource Set1) is shown as having an antenna switching use case. As shown, this example antenna switching SRS resource set includes a first SRS resource (shown as SRS Resource A) and a second SRS resource (shown as SRS Resource B). Thus, antenna switching SRS may be transmitted in SRS Resource A (e.g., a first time-frequency resource) using antenna port0and antenna port1and may be transmitted in SRS Resource B (e.g., a second time-frequency resource) using antenna port2and antenna port3.

As shown by reference number420, a second SRS resource set (e.g., shown as SRS Resource Set2) may be a codebook use case. As shown, this example codebook SRS resource set includes only the first SRS resource (shown as SRS Resource A). Thus, codebook SRSs may be transmitted in SRS Resource A (e.g., the first time-frequency resource) using antenna port0and antenna port1. In this case, the UE120may not transmit codebook SRSs in SRS Resource B (e.g., the second time-frequency resource) using antenna port2and antenna port3.

In some examples, a UE120and/or a network node110may support codebook (CB) based PUSCH transmissions and non-codebook (NCB) based PUSCH transmissions. For CB based PUSCH transmissions, a UE120may be configured with one SRS resource set with the use case (sometimes referred to as “usage”) set to codebook. In such examples, a maximum of four SRS resources within the SRS resource set may be configured for the UE120. In some examples, each SRS resource may be RRC configured with a number of ports (e.g., using a nrofSRS-Ports information element). An SRS resource indicator field (SRI) of an uplink DCI (e.g., a DCI scheduling a PUSCH transmission) associated with a CB based PUSCH transmission may indicate one SRS resource. A number of ports configured for the indicated SRS resource determines the number of antenna ports for the PUSCH transmission. Moreover, the UE120may transmit the PUSCH transmission using a same spatial domain filter (e.g., uplink beam) as the indicated SRS resource. A “precoding information and number of layers” field of the uplink DCI may indicate number of layers (e.g., rank) and a transmitted precoding matrix indicator (TPMI) for the scheduled PUSCH transmission.

For NCB based transmissions, a UE120may be configured with one SRS resource set with the use case set to non-codebook. In such examples, a maximum of four SRS resources within the SRS resource set may be configured for the UE120, with each SRS resource having one port. The SRI of an uplink DCI associated with a NCB based SRS transmission may indicate one or multiples SRS resources, with the number of indicated SRS resources corresponding to the rank (e.g., number of layers) for the scheduled PUSCH. In such examples, a scheduled PUSCH transmission may be transmitted with the same precoder as well as spatial domain filter (e.g., uplink beam) as the indicated SRS resources.

In some examples, for both CB based transmissions and NCB based transmissions, a size of the SRI field may be a function of a quantity of SRS resources within the SRS resource set. The indicated SRI in slot n may be associated with the most recent transmission of one or more SRS resources identified by the SRI that occurred prior to a physical downlink control channel (PDCCH) communication carrying the SRI. Additional details of associating SRS resources and/or SRS resource sets with SRS transmissions are described in more detail below in connection withFIGS.5-6B.

FIG.5is a diagram illustrating an example500associated with single DCI based time division multiplex (TDM) SRS transmission, in accordance with the present disclosure. In some aspects, the features shown and described in connection withFIG.5may be referred to an sDCI transmission mode or, more simply, an sDCI mode.

In some examples, a UE120may be scheduled by a single DCI to transmit multiple SRS repetitions in a TDM manner. Each SRS repetition may be associated with the same transport block (TB) (e.g., each of the different repetitions may be used to transmit the same data packet), but each SRS repetition may correspond to different transmission parameters, such as a beam parameter, a spatial relation parameter, a transmission configuration indicator (TCI) state parameter, a power control parameter, a precoding parameter, or a similar parameter. In some cases, SRS repetitions scheduled by a single DCI may belong to two sets of SRS repetitions, with each set of SRS repetitions corresponding to a different set of transmission parameters (e.g., beam, spatial relation, TCI, power control, or precoding).

More particularly,FIG.5shows an example in which an uplink DCI502schedules four SRS repetitions, including a first SRS repetition504, a second SRS repetition506, a third SRS repetition508, and a fourth SRS repetition510. The SRS repetitions504,506,508,510may be associated with two sets of transmission parameters, indicated using stippling and cross-hatching inFIG.5. For example, as shown using stippling, the first SRS repetition504and the third SRS repetition508may be associated with a first set of repetitions using a first beam and/or a first set of power control parameters, among other parameters. In some cases, the SRS repetitions associated with the first set of SRS repetitions may be targeted toward a first network node110(e.g., a first TRP). As shown using cross-hatching, the second SRS repetition506and the fourth SRS repetition510may be associated with a second set of repetitions using a second beam and/or a second set of power control parameters, among other parameters. In some cases, the SRS repetitions associated with the second set of SRS repetitions may be targeted toward a second network node110(e.g., a second TRP) different from the first network node110.

To enable the single DCI based TDM SRS transmissions shown inFIG.5, the two sets of SRS repetitions may correspond to two SRS resource sets. More particularly, the uplink DCI502may indicate two beams, two power control parameters, or two of similar transmission parameters by using two corresponding SRI fields in the uplink DCI502for both CB based SRS transmissions and NCB based SRS transmissions. For CB based SRS transmissions, the uplink DCI502may also include two TPMI fields indicating two precoders for the two sets of SRS repetitions. In the example shown inFIG.5, and as indicated by reference number512, the first set of PUSCH repetitions (e.g., the first SRS repetition504and the third SRS repetition508) may be associated with a first SRS resource set, which may be indicated by the first SRI field included in the uplink DCI502. Similarly, and as indicated by reference number514, the second set of SRS repetitions (e.g., the second SRS repetition506and the fourth SRS repetition510) may be associated with a second SRS resource set, which may be indicated by the second SRI field included in the uplink DCI502.

In some cases, a UE120may be scheduled by a single DCI (e.g., uplink DCI502) to transmit multiple SRS repetitions associated with spatial division multiplex (SDM) transmissions, frequency division multiplex (FDM) transmissions, or single frequency network (SFN) transmissions. In such cases, the DCI signaling associated with the multiple SRS repetitions associated with SDM transmissions, FDM transmissions, or SFN transmissions may be similar to the signaling described above in connection with the multiple SRS repetitions associated with TDM transmissions. For example, for multiple SRS repetitions associated with SDM transmissions, different sets of layers associated with SRS transmissions may be associated with different SRS resource sets. For multiple SRS repetitions associated with FDM transmissions, different sets of resource blocks (RBs) associated with the SRS transmissions may be associated with different SRS resource sets. And for multiple SRS repetitions associated with SFN transmissions, each layer and/or DMRS may be associated with both SRS resource sets.

Although the example shown and described in connection withFIG.5includes SRS repetitions associated with two network nodes and/or TRPs (e.g., associated with two SRS resource sets), in some other examples an uplink DCI may schedule SRS repetitions associated with a single network node and/or TRP (e.g., associated with one SRS resource set). Examples of dynamic switching between a multi-network-node and/or a multi-TRP scenario and a single-network-node and/or a single-TRP scenario are described in more detail below in connection withFIGS.6A and6B.

FIGS.6A-6Bare diagrams illustrating an example600associated with an SRS resource set indicator field, in accordance with the present disclosure.

In some examples, an uplink DCI may include an SRS resource set indicator field, indicating whether SRS repetitions are associated with a single network node and/or TRP (sometimes referred to as a single TRP (sTRP) mode) or with multiple network nodes and/or TRPs (sometimes referred to as a multiple TRP (mTRP) mode). An mTRP mode may provide support for both dynamic grant (DG) PUSCH repetition and configured grant (CG) PUSCH repetition. The SRS resource set indicator field May be a field included in an uplink DCI (e.g., a DCI format 0_1 communication or a DCI format 0_2 communication), and the presence of the field in the uplink DCI may be based on whether two SRS resource sets are configured corresponding to the DCI format. Additionally, a presence of a second SRI field and/or second TPMI field (e.g., for CB based transmissions) may be conditioned on the presence of the SRS resource set indicator field.

More particularly, as shown inFIG.6A, an uplink DCI602may schedule four SRS repetitions, in a similar manner as described above in connection with uplink DCI502. In this example, the four SRS repetitions may be associated with one of four repetition patterns, indicated by reference numbers604,606,608, and610. In the first example, indicated by reference number604, each SRS repetition is associated with the same SRS resource set (e.g., the first SRS resource set), and thus all SRS repetitions may be targeted toward the same network node and/or TRP (e.g., the example shown by reference number604may correspond to an sTRP mode). In such examples, the SRS resource set indicator field may indicate a codepoint of “00.” Similarly, in the second example, indicated by reference number606, each SRS repetition is associated with the same SRS resource set, but in this example the SRS resource set is the second SRS resource set. Thus, all SRS repetitions in the example depicted by reference number606may be targeted toward the same network node and/or TRP (e.g., an sTRP mode), which may be a different network node and/or TRP than is associated with the first example indicated by reference number604. In such examples, the SRS resource set indicator field may indicate a codepoint of “01.”

In the third example, indicated by reference number608, two of the SRS repetitions (e.g., the first and the third SRS repetitions) are associated with the first SRS resource set (e.g., targeted toward a first network node and/or TRP), and the other two SRS repetitions (e.g., the second and the fourth SRS repetitions) are associated with the second SRS resource set (e.g., targeted toward a second network node and/or TRP). In that regard, the third example may be associated with an mTRP mode and may be substantially similar to the example described above in connection withFIG.5. In such examples, the SRS resource set indicator field may indicate a codepoint of “10.” The fourth example, indicated by reference number610, may be similar to the third example but with the SRS repetitions in a different order. More particularly, in this example the first and the third SRS repetitions are associated with the second SRS resource set (e.g., targeted toward the second network node and/or TRP), and the other two SRS repetitions (e.g., the second and the fourth SRS repetitions) are associated with a first SRS resource set (e.g., targeted toward the first network node and/or TRP). In such examples, the SRS resource set indicator field may indicate a codepoint of “11.”

In this way, a network node110may dynamically switch between sTRP modes and mTRP modes by indicating a corresponding codepoint (e.g., one of 00, 01, 10, or 11) in the SRS resource set indicator field of an uplink DCI. Moreover, as shown by the table indicated by reference number612inFIG.6B, the codepoint indicated by the SRS resource set indicator field may indicate which SRS resource sets are to be used, and/or which SRI and/or TPMI fields are used in the uplink DCI602. More particularly, as described above in connection with the first example indicated by reference number604, a codepoint of 00 may indicate an sTRP mode associated with the first SRS resource set (e.g., all SRS repetitions are associated with the first SRS resource set and/or targeted toward the same network node and/or TRP, shown as TRP1inFIG.6B). In such examples, only a first SRI field (for both CB and NCB based transmissions) and/or a first TPMI field (for CB based transmissions) may be used in the uplink DCI602(e.g., a second SRI field and a first TPMI field in the uplink DCI602may be unused in this example). As described above in connection with the second example indicated by reference number606, a codepoint of 01 may indicate an sTRP mode associated with the second SRS resource set (e.g., all PUSCH repetitions are associated with the second SRS resource set and/or targeted toward the same network node and/or TRP, shown as TRP2inFIG.6B). In such examples, only the first SRI field and/or the first TPMI field may be used in the uplink DCI602(e.g., the second SRI field and the first TPMI field in the uplink DCI602may be unused in this example).

As described above in connection with the third example indicated by reference number608, a codepoint of 10 may indicate an mTRP mode associated with a transmission order of TRP1, TRP2(e.g., the first and third PUSCH repetitions are associated with the first SRS resource set and/or targeted toward TRP1, and the second and fourth PUSCH repetitions are associated with the second SRS resource set and/or targeted toward TRP2). In such examples, both the first SRI field and/or the first TPMI field and the second SRS field and/or the second TPMI field may be used in the uplink DCI602. Similarly, as described above in connection with the fourth example indicated by reference number610, a codepoint of 11 may indicate an mTRP mode associated with a transmission order of TRP2, TRP1(e.g., the first and third PUSCH repetitions are associated with the second SRS resource set and/or targeted toward TRP2, and the second and fourth PUSCH repetitions are associated with the first SRS resource set and/or targeted toward TRP1). In such examples, both the first SRI field and/or the first TPMI and the second SRS field and/or the second TPMI field may be used in the uplink DCI602.

As indicated above,FIGS.6A-6Bare provided as an example. Other examples may differ from what is described with respect toFIGS.6A-6B.

FIGS.7A-7Care diagrams illustrating examples700,710,720of FD communication in accordance with the present disclosure. FD communication in a wireless network refers to simultaneous bi-directional communication between devices in the wireless network. For example, a UE operating in an FD mode may transmit an uplink communication and receive a downlink communication at the same time (e.g., in the same slot or the same symbol). Half duplex (HD) communication in a wireless network refers to unidirectional communications (e.g., only downlink communication or only uplink communication) between devices at a given time (e.g., in a given slot or a given symbol).

The example700ofFIG.7Aincludes a UE1702(e.g., UE120) and two network nodes (e.g., TRPs)704-1,704-2(e.g., network nodes110), where the UE1702is sending UL transmissions to the network node704-1and is receiving DL transmissions from the network node704-2. In the example700ofFIG.7A, FD is enabled for the UE1702, but not for the network nodes704-1,704-2. Put another way, the network nodes704-1,704-2are operating in an HD mode. The example710ofFIG.7Bincludes two UEs, shown as UE1702-1and UE2702-2, and a network node704, where the UE1702-1is receiving a DL transmission from the network node704and the UE2702-2is transmitting an UL transmission to the network node704. In the example710ofFIG.7B. FD is enabled for the network node704, but not for the UE1702-1and the UE2702-2(e.g., the UE1702-1and the UE2702-2are operating in an HD mode). The example720ofFIG.7Cincludes a UE1702and a network node704, where the UE1702is receiving a DL transmission from the network node704and the UE1702is transmitting an UL transmission to the network node704. In the example720ofFIG.7C, FD is enabled for both the UE1702and the network node704.

In some examples, a wireless communication device operating in an FD mode (e.g., the UE1702in examples700and/or720, and/or the network node704in examples710and/or720), may be operating in an in-band FD (IBFD) mode or a sub-band FD (SBFD) mode. In an IBFD mode, a wireless communication device May transmit and receive communications on the same time and frequency resources (e.g., DL resources and UL resources may at least partially overlap in the time and frequency domains). In an SBFD mode, a wireless communication device may transmit and receive communications at the same time but on different frequency resources. In such examples, a DL resource may be separated from an UL resource by a guard band. Examples of IBFD operation and SBFD operation are described in more detail below in connection withFIG.8.

As indicated above,FIGS.7A-7Care provided as one or more examples. Other examples may differ from what is described with regard toFIGS.7A-7C.

FIG.8is a diagram illustrating examples800,805, and810of FD communication in a wireless network, in accordance with the present disclosure.

As shown inFIG.8, examples800and805show examples of IBFD communication. In IBFD, a UE may transmit an uplink communication to a network node and receive a downlink communication from the network node on the same time and frequency resources. As shown in example800, in a first example of IBFD, the time and frequency resources for uplink communication may fully overlap with the time and frequency resources for downlink communication. As shown in example805, in a second example of IBFD, the time and frequency resources for uplink communication may partially overlap with the time and frequency resources for downlink communication.

As further shown inFIG.8, example810shows an example of SBFD communication, which may also be referred to as sub-band frequency division duplex (SBFDD) or flexible duplex. In SBFD, a network node may transmit a downlink communication to a UE and receive an uplink communication from the same UE or a different UE at the same time, but on different frequency resources. For example, the different frequency resources may be sub-bands of a frequency band, such as a time division duplexing (TDD) band. In this case, the frequency resources used for downlink communication may be separated from the frequency resources used for uplink communication, in the frequency domain, by a guard band.

In some examples, channel characteristics, communication parameters, and similar properties may differ between an FD set of symbols (e.g., slots), such as slots semi-statically configured as SBFD slots, and a non-FD set of symbols (sometimes referred to as a TDD set of symbols), such as slots semi-statically configured as non-SBFD slots. For example, a link quality between an FD set of symbols and a non-FD set of symbols may differ because in an FD set of symbols there may be residual interference (sometimes referred to as crosslink interference (CLI)) in addition to inter-network-node interference, while a non-FD set of symbols may only experience inter-network-node interference. Moreover, a network node may use a different reception combiner or different reception beam in the FD set of symbols than is used in the non-FD set of symbols because a reception combiner or reception beam used in the non-FD set of symbols may be jammed by interference and/or CLI in the FD set of symbols. Moreover, uplink frequency resources associated with the FD set of symbols and the non-FD set of symbols may be different, such as where frequency resources associated with an SBFD slot may have a smaller span than a span of frequency resources associated with the non-SBFD slot. Additionally, or alternatively, a UE120may use a different transmission power or per-RB power in the FD set of symbols and the non-FD set of symbols. Moreover, a reception (e.g., uplink) panel at a network node110may be different in the FD set of symbols and the non-FD set of symbols, and/or the virtualization of port to antenna elements may be different in the FD set of symbols and the non-FD set of symbols, such as for a purpose of utilizing a baseband transceiver unit (TXRU) more efficiently.

Accordingly, in some examples, a UE120may be configured with different SRS resource sets for the FD set of symbols and the non-FD set of symbols, or else may be configured with different groups of SRS resource for the FD set of symbols and the non-FD set of symbols. More particularly, in some examples, a UE120may be configured with two SRS resource sets, with a first SRS resource set corresponding to the FD set of symbols and a second SRS resource set corresponding to the non-FD set of symbols. In some examples, this may be referred to as “duplex-specific SRS resource sets configuration.” In some other examples, a UE120may be configured with a single SRS resource set, with a first group of SRS resources of the SRS resource set (e.g., a group of N SRS resources) corresponding to the FD set of symbols and a second group of SRS resources of the SRS resource set (e.g., a group of M SRS resources) corresponding to the non-FD set of symbols (e.g., the UE120may be configured with a single SRS resource set with different parameters for the N SRS resources associated with the FD set of symbols and the M SRS resources associated with the non-FD set of symbols). In some examples, this may be referred to as “shared SRS resources for FD and non-FD.”

In examples in which a UE120is to transmit an uplink transmission repetition (e.g., a PUSCH repetition or a PUCCH repetition, such as one of the uplink transmission repetitions described above in connection withFIGS.5-6B), potential repetition occasions may extend across FD sets of symbols (e.g., SBFD slots) and non-FD sets of symbols (e.g., non-SBFD slots or TDD slots). Accordingly, SRS resources associated with the potential repetition occasions may differ, such as being associated with different SRS resource sets (in the case of duplex-specific SRS resource sets configuration) or being associated with different groups of SRS resources within an SRS resource set (in the case of shared SRS resources for FD and non-FD). However, there is no mechanism for a network node110to signal to a UE120which SRS resources are to be used for a given uplink transmission repetition and/or whether a given uplink transmission repetition is to extend across the FD set of symbols and the non-FD set of symbols. This may result in communication errors when a UE120that is configured with the SRS resources associated with the FD set of symbols and the SRS resources associated with the non-FD set of symbols performs an uplink transmission repetition, leading to high power, computing, and network resource consumption to correct communication errors and otherwise inefficient usage of network resources.

Some techniques and apparatuses described herein enable signaling of SRS resources that are to be used for a given uplink transmission repetition and/or an indication of whether a given uplink transmission repetition is to extend across an FD set of symbols and a non-FD set of symbols. In some aspects, a UE may be configured with SRS resources associated with an FD set of symbols (e.g., one or more SBFD slots) and SRS resources associated with a non-FD set of symbols (e.g., one or more non-SBFD slots). For example, the UE may be configured with two SRS resource sets, one corresponding to the FD set of symbols and one corresponding to the non-FD set of symbols, or else the UE may be configured with one SRS resource set that includes a first group of SRS resources associated with the FD set of symbols and a second group of resources associated with the non-FD set of symbols. The UE may transmit multiple SRSs using the configured resources (e.g., one using the SRS resources associated with the FD set of symbols and another using the SRS resources associated with the non-FD set of symbols), and, based at least in part on the SRS transmissions, receive a downlink communication (e.g., an RRC communication and/or a DCI communication) indicating one or more SRS resources that are to be used for an uplink transmission repetition (e.g., a PUSCH repetition or a PUCCH repetition). Based at least in part on the downlink communication, the UE may identify whether the uplink transmission repetition is to extend across the FD set of symbols and the non-FD set of symbols, or else whether the uplink transmission repetition is to be confined to one of only the FD set of symbols or only the non-FD set of symbols. Accordingly, the UE may transmit the uplink transmission repetition in one of only the FD set of symbols, only the non-FD set of symbols, or both the FD set of symbols and the non-FD set of symbols. As a result, the network node and the UE may communicate with a reduced error rate, resulting in reduced power, computing, and network resource consumption that may otherwise be required to correct communication errors, and otherwise more efficient usage of network resources.

FIGS.9A-9Fare diagrams illustrating an example900associated with uplink transmission repetition for FD and non-FD sets of symbols, in accordance with the present disclosure. Example900includes communication between a network node110and a UE120. In some aspects, the network node110and the UE120may be included in a wireless network, such as wireless network100. The network node110and the UE120may communicate via a wireless access link, which may include an uplink and a downlink. In some aspects, one or both of the network node110and the UE120may be capable of communicating in an FD mode. Moreover, in some aspects, the UE120may have a capability of identifying when the network node110is communicating in an FD mode. In that regard, in some aspects, the UE120may be referred to as an SBFD-aware UE.

As shown inFIG.9A, the network node110may transmit, and the UE120may receive, a downlink communication indicating certain parameters associated with an uplink transmission repetition, such as a PUSCH repetition or a PUCCH repetition. In some aspects, the network node110may transmit, and the UE120may receive, a DCI communication902indicating certain parameters associated with the uplink transmission repetition, as shown inFIG.9A. Additionally, or alternatively, the network node110may transmit, and the UE120may receive, an RRC communication indicating certain parameters associated with the uplink transmission repetition, which may be transmitted instead of the DCI communication902and/or which may indicate certain of the parameters described herein as being indicated by the DCI communication902. For example, in aspects associated with a Type 1 CG PUSCH and/or a periodic or semi-persistent PUCCH, certain parameters described herein as being indicated by the DCI communication902may instead be indicated by an RRC communication.

In some aspects, the DCI communication902(and/or an RRC communication, as described above) may include one or more SRIs associated with the uplink transmission repetition (shown as SRI1and SRI2inFIG.9A), one or more TPMIs associated with the uplink transmission repetition (shown as TPMI1and TPMI2inFIG.9A), and a duplex repetition indicator field904. In some aspects, only one SRI field and/or TPMI field may be needed and/or included in the DCI communication902, which is described in more detail below. This is shown inFIG.9Ausing dashed lines for the SRI2and TPMI2, indicating that, in this aspect, the DCI communication902may omit the second SRI field and/or the second TPMI field.

In some aspects, the duplex repetition indicator field904may be a dedicated bitfield used to indicate whether an uplink transmission repetition is to span repetition occasions in FD slots and non-FD slots. In some other aspects, the duplex repetition indicator field904may be an existing field of a downlink communication (e.g., the DCI communication902or an RRC communication) that is used to indicate whether an uplink transmission repetition is to span repetition occasions in FD slots and non-FD slots. For example, in some aspects the duplex repetition indicator field904may be an SRS resource set indicator field that is reused for a purpose of indicating whether an uplink transmission repetition is to span repetition occasions in FD slots and non-FD slots.

In some aspects, a codepoint or similar parameter may be indicated by the duplex repetition indicator field904, which may indicate whether an uplink transmission repetition is duplex-specific (e.g., whether the uplink transmission repetition is to be transmitted using repetition occasions in only one of the FD set of symbols or the non-FD set of symbols), or whether an uplink transmission repetition is not duplex-specific (e.g., whether the uplink transmission repetition is to be transmitted using repetition occasions in both the FD set of symbols or the non-FD set of symbols). For example, in the aspect shown inFIG.9A, the duplex repetition indicator field904indicates a codepoint of “00,” which may indicate non-FD repetition (e.g., which may indicate that the uplink transmission repetition is to be transmitted using only repetition occasions in the non-FD set of symbols). In that regard, when transmitting the uplink transmission repetition, the UE120may use only occasions occurring in the non-FD set of symbols (e.g., non-SBFD slots).

More particularly, as shown inFIG.9A, and as indicated by reference number906, the UE120may be configured with a slot pattern including both FD slots908(e.g., SBFD slots, shown as a first FD slot908-1through an eighth FD slot908-8) and non-FD slots910(e.g., non-SBFD slots, shown as a first non-FD slot910-1and a second non-FD slot910-2). Based at least in part on receiving the DCI communication902that schedules an uplink transmission repetition and that indicates the codepoint “00” in the duplex repetition indicator field904, the UE120may identify that the uplink transmission repetition is to be transmitted using only non-FD slots910. Accordingly, as indicated by reference number912, the UE120may transmit a first repetition (shown as repetition #0) in the first non-FD slot910-1, and a second repetition (shown as repetition #1) in the second non-FD slot910-2, skipping any repetition occasions occurring in FD slots908(e.g., skipping repetition occasions occurring in the fifth FD slot908-5through the eighth FD slot908-8).

In aspects in which the UE120is configured with two SRS resource sets with usage set to codebook or non-codebook, with one SRS resource set associated with the FD slots908and another SRS resource set associated with the non-FD slots910, the indication in the duplex repetition indicator field904(e.g., the codepoint “00” in the example depicted inFIG.9A) may serve to indicate that the SRS resource set corresponding to the non-FD slots910is associated with the uplink transmission repetition. Put another way, in aspects involving two SRS resource sets, with a first SRS resource set associated with the FD set of symbols and the second SRS resource set associated with the non-FD set of symbols, the codepoint “00” may indicate that the second SRS resource set is associated with the uplink transmission repetition. Moreover, in such aspects, the DCI communication902may include a single SRI (e.g., SRI1) and/or a single TPMI (e.g., TPMI1, for CB based transmissions) that are associated with the SRS resource set corresponding to the non-FD slots910. The DCI communication902may indicate additional parameters, such as a number of layers parameter (sometimes referred to as numLayers) that is associated with the SRS resource set corresponding to the non-FD slots910.

In aspects in which the UE120is configured with a single SRS resource set with usage set to codebook or non-codebook, with a first group of SRS resources (e.g., N SRS resources) associated with the FD slots908and a second group of SRS resources (e.g., M SRS resources) associated with the non-FD slots910, the indication in the duplex repetition indicator field904(e.g., the codepoint “00” in the example depicted inFIG.9A) may serve to indicate that the group of SRS resources corresponding to the non-FD slots910(e.g., the M SRS resources) are associated with the uplink transmission repetition. Put another way, in aspects involving a single SRS resource set, with a first group of SRS resources of the SRS resource set associated with the FD set of symbols and a second group of SRS resources of the SRS resource set associated with the non-FD set of symbols, the codepoint “00” may indicate that the second group of SRS resources is associated with the uplink transmission repetition. Moreover, in such aspects, the DCI communication902may include a single SRI (e.g., SRI1) and/or a single TPMI (e.g., TPMI1, for CB based transmissions) that are associated with the group of SRS resources (e.g., the M SRS resources) corresponding to the non-FD slots910. The DCI communication902may indicate additional parameters, such as a number of layers parameter (e.g., numLayers) that is associated with the group of SRS resources (e.g., the M SRS resources) corresponding to the non-FD slots910.

In the aspect shown inFIG.9B, the duplex repetition indicator field904indicates a codepoint of “01,” which may indicate FD repetition (e.g., which may indicate that the uplink transmission repetition is to be transmitted using only repetition occasions in the FD set of symbols). In that regard, when transmitting the uplink transmission repetition, the UE120may use only occasions occurring in FD sets of symbols (e.g., SBFD slots). More particularly, based at least in part on receiving the DCI communication902that schedules an uplink transmission repetition and that indicates the codepoint “01” in the duplex repetition indicator field904, the UE120may identify that the uplink transmission repetition is to be transmitted using only FD slots908. Accordingly, as indicated by reference number914, the UE120may transmit a first repetition (shown as repetition #0) in the first FD slot908-1, a second repetition (shown as repetition #1) in the second FD slot908-2, and so forth (shown through a sixth repetition, repetition #5, in the sixth FD slot908-6), skipping any repetition occasions occurring in non-FD slots910(e.g., skipping a repetition occasion occurring in the first non-FD slot910-1).

In aspects in which the UE120is configured with two SRS resource sets with usage set to codebook or non-codebook, one associated with the FD slots908and another one associated with the non-FD slots910, the indication in the duplex repetition indicator field904(e.g., the codepoint “01” in the example depicted inFIG.9B) may indicate that the SRS resource set corresponding to the FD slots908is associated with the uplink transmission repetition. Put another way, in aspects involving two SRS resource sets, with a first SRS resource set associated with the FD set of symbols and the second SRS resource set associated with the non-FD set of symbols, the codepoint “01” may indicate that the first SRS resource set is associated with the uplink transmission repetition. Moreover, in such aspects, the DCI communication902may include a single SRI (e.g., SRI1), a single TPMI (e.g., TPMI1, for CB based transmissions), and/or a number of layers parameter (e.g., numLayers) that are associated with the SRS resource set corresponding to the FD slots908.

In aspects in which the UE120is configured with a single SRS resource set with usage set to codebook or non-codebook, with a first group of SRS resources (e.g., N SRS resources) associated with the FD slots908and a second group of SRS resources (e.g., M SRS resources) associated with the non-FD slots910, the indication in the duplex repetition indicator field904(e.g., the codepoint “01” in the example depicted inFIG.9B) may indicate that the group of SRS resources corresponding to the FD slots910(e.g., the N SRS resources) are associated with the uplink transmission repetition. Put another way, in aspects involving a single SRS resource set, with a first group of SRS resources of the SRS resource set associated with the FD set of symbols and a second group of SRS resources of the SRS resource set associated with the non-FD set of symbols, the codepoint “01” may indicate that the first group of SRS resources are associated with the uplink transmission repetition. Moreover, in such aspects, the DCI communication902may include a single SRI (e.g., SRI1), a single TPMI (e.g., TPMI1, for CB-based transmissions), and/or a number of layers parameter (e.g., numLayers) that are associated with the group of SRS resources (e.g., the N SRS resources) corresponding to the FD slots908.

In the aspect shown inFIG.9C, the duplex repetition indicator field904indicates a codepoint of “10,” which may indicate non-duplex-specific repetition (e.g., which may indicate that the uplink transmission repetition is to be transmitted using repetition occasions across the FD set of symbols and the non-FD set of symbols). In that regard, when transmitting the uplink transmission repetition, the UE120may use occasions occurring in both FD sets of symbols (e.g., SBFD slots) and non-FD sets of symbols (e.g., non-SBFD slots). More particularly, based at least in part on receiving the DCI communication902that schedules an uplink transmission repetition and that indicates the codepoint “10” in the duplex repetition indicator field904, the UE120may identify that the uplink transmission repetition is to be transmitted using both FD slots908and non-FD slots. Moreover, the codepoint “10” may further indicate that a first slot for transmission (e.g., when available slot counting is enabled for repetition) is mapped to a first available non-FD slot910. Accordingly, as indicated by reference number916, the UE120may transmit a first repetition (shown as repetition #0) in the first non-FD slot910-1, a second repetition (shown as repetition #1) in the next available repetition occasion, which in this example is the fifth FD slot908-5, and so forth for each consecutive repetition (shown through a sixth repetition, repetition #5, in the second non-FD slot910-2), without skipping any available repetition occasions.

In aspects in which the UE120is configured with two SRS resource sets with usage set to codebook or non-codebook, one associated with the FD slots908and another one associated with the non-FD slots910, the indication in the duplex repetition indicator field904(e.g., the codepoint “10” in the example depicted inFIG.9C) may indicate that both SRS resource sets are associated with the uplink transmission repetition. Put another way, in aspects involving two SRS resource sets, with a first SRS resource set associated with the FD set of symbols and the second SRS resource set associated with the non-FD set of symbols, the codepoint “10” may indicate that both the first SRS resource set and the second SRS resource set are associated with the uplink transmission repetition. Moreover, in such aspects, the DCI communication902may include two SRIs (e.g., SRI1and SRI2), with the first SRI corresponding to the first SRS resource set and the second SRI corresponding to the second SRS resource set, and two TPMIs (e.g., TPMI1and TPMI2, for CB based transmissions), with the first TPMI corresponding to the first SRS resource set and the second TPMI corresponding to the second SRS resource set. In some aspects, the DCI communication may further indicate a timing offset (e.g., in number of slots) between a slot containing the DCI communication902(e.g., a slot carrying a grant that schedules a PUSCH repetition) and a first slot containing the scheduled transmission (e.g., the PUSCH repetition scheduled via the DCI communication902), which is sometimes referred to as a K2 value. In such aspects, the timing offset (e.g., the K2 value) may serve as a reference for a first available slot based on the codepoint. Aspects of the K2 value are described in more detail below. In this aspect, the repetitions #0and #5of the uplink transmission may be associated with the non-FD SRS resource set with one SRI and one TPMI. The uplink repetitions #1. #2. #3, and #4may be associated with the FD SRS resource set with a different SRI and a different TPMI.

In aspects in which the UE120is configured with a single SRS resource set with usage set to codebook or non-codebook, with a first group of SRS resources (e.g., N SRS resources) associated with the FD slots908and a second group of SRS resources (e.g., M SRS resources) associated with the non-FD slots910, the indication in the duplex repetition indicator field904(e.g., the codepoint “10” in the example depicted inFIG.9B) may indicate that both the group of SRS resources associated with the FD slots908(e.g., the N SRS resources) and the group of SRS resources associated with the non-FD slots910(e.g., the M SRS resources) are associated with the uplink transmission repetition. Put another way, in aspects involving a single SRS resource set, with a first group of SRS resources of the SRS resource set associated with the FD set of symbols and a second group of SRS resources of the SRS resource set associated with the non-FD set of symbols, the codepoint “10” may indicate that both the first group of SRS resources and the second group of SRS resources are associated with the uplink transmission repetition. Moreover, in such aspects, the DCI communication902may include two SRIs (e.g., SRI1and SRI2), with the first SRI corresponding to the first group of SRS resources (e.g., the N resources) and the second SRI corresponding to the second group of SRS resources (e.g., the M resources), and two TPMIs (e.g., TPMI1and TPMI2, for CB based transmissions), with the first TPMI corresponding to the first group of SRS resources (e.g., the N resources) and the second TPMI corresponding to the second group of SRS resources (e.g., the M resources). In some aspects, a size of the SRI bitfields and/or the TPMI bitfields may be based on a maximum value between a quantity of SRS resources included in the first group of SRS resources (e.g., N) and a quantity of SRS resources included in the second group of SRS resources (e.g., M). The first SRI (e.g., SRI1) may be interpreted with a number of SRS resources (sometimes referred to as NSRSor NSRS0_2) equal to the quantity of SRS resources included in the first group of SRS resources (e.g., N), and the second SRI (e.g., SRI2) may be interpreted with a number of SRS resources (e.g., NSRSor NSRS0_2) equal to the quantity of SRS resources included in the second group of SRS resources (e.g., M). In some aspects, the DCI communication902may further indicate a timing offset (e.g., a K2 value) that serves as a reference for a first available slot based on the codepoint, which is described in more detail below. In this aspect, the repetitions #0and #5of the uplink transmission may be associated with the non-FD group of resources with one SRI and one TPMI. The uplink repetitions #1, #2. #3, and #4may be associated with the FD group of resources with a different SRI and a different TPMI.

In the aspect shown inFIG.9D, the duplex repetition indicator field904indicates a codepoint of “11,” which may indicate non-duplex-specific repetition (e.g., which may indicate that the uplink transmission repetition is to be transmitted using repetition occasions across the FD set of symbols and the non-FD set of symbols). In that regard, when transmitting the uplink transmission repetition, the UE120may use occasions occurring in both FD sets of symbols (e.g., SBFD slots) and non-FD sets of symbols (e.g., non-SBFD slots). More particularly, based at least in part on receiving the DCI communication902that schedules an uplink transmission repetition and that indicates the codepoint “11” in the duplex repetition indicator field904, the UE120may identify that the uplink transmission repetition is to be transmitted using both FD slots908and non-FD slots. Moreover, the codepoint “11” may further indicate that a first slot for transmission (e.g., when available slot counting is enabled for repetition) is mapped to a first available FD slot908. Accordingly, as indicated by reference number918, the UE120may transmit a first repetition (shown as repetition #0) in the first FD slot908-1, a second repetition (shown as repetition #1) in the next available repetition occasion, which in this example is the second FD slot908-2, and so forth for each consecutive repetition (shown through a sixth repetition, repetition #5, in the fifth FD slot908-5), without skipping any available repetition occasions.

In aspects in which the UE120is configured with two SRS resource sets with usage set to codebook or non-codebook, one associated with the FD slots908and one associated with the non-FD slots910, the indication in the duplex repetition indicator field904(e.g., the codepoint “11” in the example depicted inFIG.9D) may indicate that both SRS resource sets are associated with the uplink transmission repetition. Put another way, in aspects involving two SRS resource sets, with a first SRS resource set associated with the FD set of symbols and the second SRS resource set associated with the non-FD set of symbols, the codepoint “11” may indicate that both the first SRS resource set and the second SRS resource set are associated with the uplink transmission repetition. Moreover, in such aspects, the DCI communication902may include two SRIs (e.g., SRI1and SRI2), with the first SRI corresponding to the first SRS resource set and the second SRI corresponding to the second SRS resource set, and two TPMIs (e.g., TPMI1and TPMI2, for CB based transmissions), with the first TPMI corresponding to the first SRS resource set and the second TPMI corresponding to the second SRS resource set. In some aspects, the DCI communication may further indicate a timing offset (e.g., a K2 value), which may serve as a reference for a first available slot based on the codepoint, as described in more detail below. In this aspect, the repetitions #0, #1, #2, #3, and #5of the uplink transmission may be associated with the FD SRS resource set with one SRI and one TPMI. The uplink repetition #4may be associated with the non-FD SRS resource set with a different SRI and a different TPMI.

In aspects in which the UE120is configured with a single SRS resource set with usage set to codebook or non-codebook, with a first group of SRS resources (e.g., N SRS resources) associated with the FD slots908and a second group of SRS resources (e.g., M SRS resources) associated with the non-FD slots910, the indication in the duplex repetition indicator field904(e.g., the codepoint “11” in the example depicted inFIG.9D) may indicate that both the group of SRS resources associated with the FD slots908(e.g., the N SRS resources) and the group of SRS resources associated with the non-FD slots910(e.g., the M SRS resources) are associated with the uplink transmission repetition. Put another way, in aspects involving a single SRS resource set, with a first group of SRS resources of the SRS resource set associated with the FD set of symbols and a second group of SRS resources of the SRS resource set associated with the non-FD set of symbols, the codepoint “11” may indicate that both the first group of SRS resources and the second group of SRS resources are associated with the uplink transmission repetition. Moreover, in such aspects, the DCI communication902may include two SRIs (e.g., SRI1and SRI2), with the first SRI corresponding to the first group of SRS resources (e.g., the N resources) and the second SRI corresponding to the second group of SRS resources (e.g., the M resources), and two TPMIs (e.g., TPMI1and TPMI2, for CB based transmissions), with the first TPMI corresponding to the first group of SRS resources (e.g., the N resources) and the second TPMI corresponding to the second group of SRS resources (e.g., the M resources). In some aspects, a size of the SRI bitfields and/or the TPMI bitfields may be based on a maximum value between a quantity of SRS resources included in the first group of SRS resources (e.g., N) and a quantity of SRS resources included in the second group of SRS resources (e.g., M). The first SRI (e.g., SRI1) may be interpreted with a number of SRS resources (e.g., NSRSor NSRS0_2) equal to the quantity of SRS resources included in the first group of SRS resources (e.g., N), and the second SRI (e.g., SRI2) may be interpreted with a number of SRS resources (e.g., NSRSor NSRS0_2) equal to the quantity of SRS resources included in the second group of SRS resources (e.g., M). In some aspects, the DCI communication may further indicate a timing offset (e.g., a K2 parameter) that serves as a reference for a first available slot based on the codepoint, which is described in more detail below. In this aspect, the repetitions #0, #1, #2, #3, and #5of the uplink transmission may be associated with the FD group of resources with one SRI and one TPMI. The uplink repetition #4may be associated with the non-FD group of resources with a different SRI and a different TPMI.

In some aspects, one or more indications (e.g., codepoints) may be included in the DCI communication902or another downlink communication (e.g., an RRC communication) in order to indicate whether a frequency offset is to be applied to repetitions occurring in different slot types. For example, in the aspect shown inFIG.9E, the duplex repetition indicator field904indicates a codepoint of “10,” which may indicate non-duplex-specific repetition (e.g., which may indicate that the uplink transmission repetition is to be transmitted using repetition occasions across the FD set of symbols and the non-FD set of symbols). Moreover, in the example depicted inFIG.9E, the codepoint “10” may further indicate that no frequency offset should be added to repetitions. Accordingly, the UE120may transmit all repetitions, whether in FD slots908or non-FD slots910, using the same frequency resources.

More particularly, as shown by reference number920, in examples in which frequency hopping is not configured, each repetition may be transmitted using the same frequency resources. More particularly, as indicated by reference number922, the UE120may transmit a first repetition (shown as repetition #0) in the first FD slot908-1using certain frequency resources, a second repetition (shown as repetition #1) in the next available repetition occasion, which in this example is the second FD slot908-2, using the same frequency resources, and so forth for each consecutive repetition (shown through a fifth repetition, repetition #4, in the first non-FD slot910-1), without applying a frequency offset to repetitions occurring in different slot types. Similarly, as shown by reference number924, in examples in which frequency hopping is configured, each instance of a given frequency hop may be transmitted using the same frequency resources. More particularly, as indicated by reference number926, the UE120may transmit a first instance of a first frequency hop (shown as h0) in the first FD slot908-1, a second instance of the first frequency hop in the third FD slot908-3, and a third instance of the first frequency hop in the first non-FD slot910-1, using the same frequency resources in the FD slots908and the non-FD slot910. Similarly, the UE120may transmit a first instance of a second frequency hop (shown as h1) in the second FD slot908-2, and a second instance of the second frequency hop in the fourth FD slot908-4, using the same frequency resources for each hop.

In the aspect shown inFIG.9F, the duplex repetition indicator field904indicates a codepoint of “11,” which may indicate non-duplex-specific repetition (e.g., which may indicate that the uplink transmission repetition is to be transmitted using repetition occasions across the FD set of symbols and the non-FD set of symbols). Moreover, in the example depicted inFIG.9F, the codepoint “11” may further indicate that a frequency offset should be added to repetitions occurring in different slot types. Accordingly, the UE120may transmit repetitions occurring in FD slots908using a first set of frequency resources and repetitions occurring in non-FD slots910using a second set of frequency resources different from the first set of frequency resources.

More particularly, reference number928shows an example in which frequency hopping is not configured and a frequency offset is applied to repetitions occurring in different slot types. More particularly, as indicated by reference number930, the UE120may transmit a first repetition (shown as repetition #0) in the first FD slot908-1using a first set of frequency resources, a second repetition (shown as repetition #1) in the next available repetition occasion, which in this example is the second FD slot908-2, using the first set of frequency resources, and so forth for each consecutive repetition in the same slot type (shown through a fourth repetition, repetition #3, in the fourth FD slot908-4). When a repetition occasion occurs in a different slot type (e.g., a non-FD slot910), the UE120may apply a frequency offset. More particularly, the UE120may transmit a fifth repetition (shown as repetition #4) in the first non-FD slot910-1by applying a frequency offset, such that the fifth repetition occurs at a bottom of bandwidth associated with the first non-FD slot910-1. This may permit more efficient allocation of uplink resources among various UEs120, because the fifth repetition does not occur in the middle of the uplink bandwidth as is the case for the example shown inFIG.9E. Similarly, as shown by reference number932, in examples in which frequency hopping is configured, instances of a given frequency hop may be transmitted using a frequency offset. More particularly, as indicated by reference number934, the UE120may transmit a first instance of a first frequency hop (shown as h0) in the first FD slot908-1using a first set of frequency resources, a second instance of the first frequency hop in the third FD slot908-3using the first set of frequency resources, and a third instance of the first frequency hop in the first non-FD slot910-1using a second set of frequency resources by applying a frequency offset to the first set of frequency resources. Similarly, the UE120may transmit a first instance of a second frequency hop (shown as h1) in the second FD slot908-2, and a second instance of the second frequency hop in the fourth FD slot908-4, using the same frequency resources for each hop (e.g., using a third set of frequency resources).

In some aspects, a single codepoint may be used to signal non-duplex-specific repetition (e.g., to signal that the uplink transmission repetition is to be transmitted using repetition occasions across the FD set of symbols and the non-FD set of symbols), and another parameter, such as a timing offset (e.g., a K2 value) may be used to indicate which slot type should be used for a first repetition of the uplink transmission repetition. For example, in some aspects, the duplex repetition indicator field904may indicate a codepoint of “10” to indicate non-duplex-specific repetition (e.g., which may indicate that the uplink transmission repetition is to be transmitted using repetition occasions across the FD set of symbols and the non-FD set of symbols), and the DCI communication902may indicate a timing offset (e.g., a K2 value) to indicate a first slot for transmission. Accordingly, when a slot that is offset from a slot containing the DCI communication902by the timing offset amount is an FD slot908, the UE120may begin the uplink transmission repetition in an FD slot908. Similarly, when a slot that is offset from a slot containing DCI communication902by the timing offset amount is a non-FD slot910, the UE120may begin the uplink transmission repetition in a non-FD slot910. In some aspects, a single codepoint with a timing offset (e.g., a K2 value) may be used to indicate non-duplex-specific transmission in instances in which available slot counting is enabled for repetition and/or in aspects in which repetitions are based on physical slot counting.

In some aspects, a single codepoint may be used to signal duplex-specific repetition (e.g., to signal that the uplink transmission repetition is to be transmitted using repetition occasions in only one of the FD set of symbols or the non-FD set of symbols) with a timing offset (e.g., a K2 value) used to indicate which slot type should be used for each repetition of the uplink transmission repetition. Additionally, or alternatively, a single codepoint may be used to signal non-duplex-specific repetition (e.g., to signal that the uplink transmission repetition is to be transmitted using repetition occasions across the FD set of symbols and the non-FD set of symbols) with a timing offset (e.g., a K2 value) used to indicate which slot type should be used for a first repetition of the uplink transmission repetition.

For example, the duplex repetition indicator field904may be a dedicated one-bit bitfield (or else may be associated with one-bit of the SRS resource set indicator field) to indicate whether repetition is duplex-specific or not duplex-specific by signaling one of codepoint “0” or codepoint “1.” When the duplex repetition indicator field904indicates the codepoint “0,” the UE120may transmit the uplink transmission repetition using only FD slots908or only non-FD slots910. The type of slots to be used (e.g., whether to use only FD slots908or only non-FD slots910) may be indicated via a timing offset (e.g., a K2 value). For example, when a slot that is offset from a slot containing DCI communication902by the timing offset amount is an FD slot908, the UE120may use only FD slots908for the uplink transmission repetition. Similarly, when a slot that is offset from a slot containing DCI communication902by the timing offset amount is a non-FD slot910, the UE120may use only non-FD slots910for the uplink transmission repetition.

Similarly, when the duplex repetition indicator field904indicates the codepoint “1,” the UE120may transmit the uplink transmission repetition using both FD slots908and non-FD slots910(e.g., the codepoint “1” may indicate that the uplink transmission repetition should extend across both FD slots908and non-FD slots908). In such aspects, the DCI communication902may indicate a timing offset (e.g., a K2 value) to indicate a first slot for transmission. Accordingly, when a slot that is offset from a slot containing DCI communication902by the timing offset amount is an FD slot908, the UE120may begin the uplink transmission repetition in an FD slot908. Similarly, when a slot that is offset from a slot containing DCI communication902by the timing offset amount is a non-FD slot910, the UE120may begin the uplink transmission repetition in a non-FD slot910.

In some aspects, the DCI communication902or a similar downlink communication (e.g., an RRC communication) may be used to signal to the UE120that a PUCCH repetition should be transmitted using only the FD set of symbols (e.g., using repetition occasion occurring only in FD slots908), only the non-FD set of symbols (e.g., using repetition occasions occurring only non-FD slots910), or using both the FD set of symbols and the non-FD set of symbols (e.g., using repetition occasions occurring in both FD slots908and non-FD slots910). In some aspects, a UE120may identify a quantity of repetitions associated with a PUCCH repetitions based at least in part on RRC configurations of a PUCCH repetition number of slots parameter (sometimes referred to as pucch-RepetitionNrofSlots) per PUCCH resource and/or based at least in part an RRC configuration of number of slots parameter (sometimes referred to as nrofSlots) per a PUCCH format configuration. In some aspects, a PUCCH repetition may be an aperiodic PUCCH repetition triggered by a DCI communication (e.g., DCI communication902), or a periodic or semi-persistent PUCCH repetition configured by an RRC communication.

In some aspects, such as when the DCI communication902or another downlink communication (e.g., an RRC communication) is used to trigger a PUCCH repetition, the DCI communication902or other downlink communication may include a bitfield to indicate whether the PUCCH repetition is a duplex-specific PUCCH repetition (e.g., whether the PUCCH repetition is to be transmitted using one of only repetition occasions occurring in FD sets of symbols or only repetition occasions occurring in non-FD sets of symbols) or whether the PUCCH repetition is a non-duplex-specific PUCCH repetition (e.g., whether the PUCCH repetition is to be transmitted using repetition occasions occurring in both FD sets of symbols and non-FD sets of symbols). For example, the DCI communication902may include a codepoint of “0” to indicate that the PUCCH repetition is a duplex-specific PUCCH repetition. In such aspects, the DCI communication may further indicate a timing offset (e.g., in number of slots) between a slot containing the DCI communication902(e.g., a slot carrying a grant that schedules a PUCCH repetition) and a first slot containing the scheduled PUCCH repetition (scheduled via the DCI communication902), which is sometimes referred to as a K1 value. In such aspects, the timing offset (e.g., the K1 value) may determine the duplex type for the PUCCH repetition. For example, when a slot that is offset from a slot containing the DCI communication902by the timing offset amount is an FD slot908, the UE120may use repetition occasions occurring only in FD slots908for the PUCCH repetition. Similarly, when a slot that is offset from a slot containing DCI communication902by the timing offset amount is a non-FD slot910, the UE120may use repetition occasions occurring only in non-FD slots910for the PUCCH repetition.

Similarly, the DCI communication902may include a codepoint of “1” to indicate that the PUCCH repetition is a non-duplex-specific PUCCH repetition. In such aspects, the DCI communication may further indicate a timing offset (e.g., the K1 value) to identify a first slot to be used for the PUCCH repetition. For example, when a slot that is offset from a slot containing the DCI communication902by the timing offset amount is an FD slot908, the UE120may begin the PUCCH repetition in an FD slot908. Similarly, when a slot that is offset from a slot containing DCI communication902by the timing offset amount is a non-FD slot910, the UE120may being the PUCCH repetition in a non-FD slot910.

Additional aspects of signaling between a network node110and UE120in connection with uplink transmission repetition for FD and non-FD sets of symbols are described in more detail below in connection withFIG.10.

As indicated above,FIG.9is provided as an example. Other examples may differ from what is described with respect toFIG.9.

FIG.10is a diagram of an example1000associated with uplink transmission repetition for FD and non-FD sets of symbols, in accordance with the present disclosure. As shown inFIG.10, a network node110(e.g., a CU, a DU, and/or an RU) may communicate with a UE120. In some aspects, the network node110and the UE120may be part of a wireless network (e.g., wireless network100). The UE120and the network node110may have established a wireless connection prior to operations shown inFIG.10. In some aspects, the network node110and/or the UE120may be capable of FD communication, and/or the UE120may be an SBFD-aware UE120.

As shown by reference number1005, the UE120may transmit, and the network node110may receive, capability information (e.g., a capabilities report). In some aspects, the capability information may indicate UE120support for uplink transmission repetition (e.g., PUSCH repetition and/or PUCCH repetition) across both the FD set of symbols and the non-FD set of symbols. More particularly, the capability information may indicate a capability of uplink transmission repetition across an FD set of symbols only (e.g., the FD slots908), a capability of uplink transmission repetition across a non-FD set of symbols only (e.g., the non-FD slots910), or a capability of uplink transmission repetition across both the FD set of symbols and the non-FD set of symbols.

As shown by reference number1010, the network node110may transmit, and the UE120may receive, configuration information. In some aspects, the UE120may receive the configuration information via one or more of RRC signaling, one or more MAC-CEs, and/or DCI, among other examples. In some aspects, the configuration information may include an indication of one or more configuration parameters (e.g., already known to the UE120and/or previously indicated by the network node110or other network device) for selection by the UE120, and/or explicit configuration information for the UE120to use to configure the UE120, among other examples.

In some aspects, the configuration information may configure one or more SRS resource sets, with the one or more SRS resource sets including one or more SRS resources associated with the FD set of symbols and one or more SRS resources associated with the non-FD set of symbols. As described above in connection withFIGS.8-9F, in some aspects the one or more SRS resource sets may include a first SRS resource set associated with repetition occasions in the FD set of symbols and a second SRS resource set associated with repetition occasions in the non-FD set of symbols (e.g., the configuration information may configure two SRS resource sets, one set associated with FD slots and a different set associated with non-FD slots). In some other aspects, the one or more SRS resource sets may include a single SRS resource set associated with a first group of SRS resources (e.g., N SRS resources) associated with repetition occasions in the FD set of symbols, and a second group of SRS resources (e.g., M SRS resources) associated with repetition occasions in the non-FD set of symbols (e.g., the configuration information may configure a single SRS resource set having two groups of SRS resources, one group associated with FD slots and a different group associated with non-FD slots).

The UE120may configure itself based at least in part on the configuration information. In some aspects, the UE120may be configured to perform one or more operations described herein based at least in part on the configuration information.

Aa shown by reference numbers1015and1020, the UE120may transmit, and the network node110may receive, multiple SRSs based at least in part on the configuration information. For example, as shown by reference number1015, the UE120may transmit, and the network node110may receive, a first SRS using the one or more SRS resources associated with the FD set of symbols (e.g., the SRS resources associated with the first SRS resource set when two SRS resource sets are configured, or the first group of SRS resources (e.g., N SRS resources) associated with the SRS resource set when a single SRS resource set is configured). Moreover, as shown by reference number1020, the UE120may transmit, and the network node110may receive, a second SRS using the one or more SRS resources associated with the non-FD set of symbols (e.g., the SRS resources associated with the second SRS resource set when two SRS resource sets are configured, or the second group of SRS resources (e.g., M SRS resources) associated with the SRS resource set when a single SRS resource set is configured).

As shown by reference number1025, the network node110may transmit, and the UE120may receive, a downlink communication indicating at least one of the one or more SRS resources associated with the FD set of symbols or the one or more SRS resources associated with the non-FD set of symbols that are to be used for an uplink transmission repetition (e.g., a PUSCH repetition or a PUCCH repetition). For example, in some aspects, the network node110may transmit, and the UE120may receive, an RRC communication indicating at least one of the one or more SRS resources associated with the FD set of symbols or the one or more SRS resources associated with the non-FD set of symbols that are to be used for an uplink transmission repetition, such as in the case of Type 1 CG PUSCH repetition. In some other aspects, the network node110may transmit, and the UE120may receive, a DCI communication (e.g., DCI communication902) indicating at least one of the one or more SRS resources associated with the FD set of symbols or the one or more SRS resources associated with the non-FD set of symbols that are to be used for an uplink transmission repetition. Moreover, as described above in connection withFIGS.9A-9F, the RRC communication and/or the DCI communication may use an SRS resource set indicator field or a dedicated bitfield (e.g., a duplex repetition indicator field, such as the duplex repetition indicator field904) to indicate the at least one of the one or more SRS resources associated with the FD set of symbols or the one or more SRS resources associated with the non-FD set of symbols that is to be used for the uplink transmission repetition in at least one of the FD set of symbols or the non-FD set of symbols.

In some aspects, the RRC communication and/or the DCI communication may indicate that the second SRS resource set or the second group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the non-FD set of symbols) is associated with the uplink transmission repetition (e.g., the uplink communication repetition is to be transmitted using only repetition occasions in the non-FD set of symbols). For example, the RRC communication and/or the DCI communication may indicate the codepoint “00” as described above in connection withFIG.9A. In some other aspects, the RRC communication and/or the DCI communication may indicate that the first SRS resource set or the first group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the FD set of symbols) is associated with the uplink transmission repetition (e.g., the uplink communication repetition is to be transmitted using only repetition occasions in the FD set of symbols). For example, the RRC communication and/or the DCI communication may indicate the codepoint “01” as described above in connection withFIG.9B.

In some other aspects, the RRC communication and/or the DCI communication may indicate that the first SRS resource set/first group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the FD set of symbols) and the second SRS resource set/second group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the non-FD set of symbols) are associated with the uplink transmission repetition (e.g., the uplink communication repetition is to be transmitted using both repetition occasions in the FD set of symbols and the non-FD set of symbols), and that the uplink transmission repetition is to begin in a slot associated with the non-FD set of symbols. For example, the RRC communication and/or the DCI communication may indicate the codepoint “10” as described above in connection withFIG.9C. In some other aspects, the RRC communication and/or the DCI communication may indicate that the first SRS resource set/first group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the FD set of symbols) and the second SRS resource set/second group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the non-FD set of symbols) are associated with the uplink transmission repetition (e.g., the uplink communication repetition is to be transmitted using both repetition occasions in the FD set of symbols and the non-FD set of symbols), and that the uplink transmission repetition is to begin in a slot associated with the FD set of symbols. For example, the RRC communication and/or the DCI communication may indicate the codepoint “11” as described above in connection withFIG.9D.

In some other aspects, the RRC communication and/or the DCI communication may indicate that the first SRS resource set/first group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the FD set of symbols) and the second SRS resource set/second group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the non-FD set of symbols) are associated with the uplink transmission repetition (e.g., the uplink communication repetition is to be transmitted using both repetition occasions in the FD set of symbols and the non-FD set of symbols), and that the uplink transmission repetition is not associated with a frequency offset. For example, the RRC communication and/or the DCI communication may indicate the codepoint “10” as described above in connection withFIG.9E. In some other aspects, the RRC communication and/or the DCI communication may indicate that the first SRS resource set/first group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the FD set of symbols) and the second SRS resource set/second group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the non-FD set of symbols) are associated with the uplink transmission repetition (e.g., the uplink communication repetition is to be transmitted using both repetition occasions in the FD set of symbols and the non-FD set of symbols), and that the uplink transmission repetition is associated with a frequency offset. For example, the RRC communication and/or the DCI communication may indicate the codepoint “11” as described above in connection withFIG.9F.

In some other aspects, the RRC communication and/or the DCI communication may indicate that the first SRS resource set/first group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the FD set of symbols) and the second SRS resource set/second group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the non-FD set of symbols) are associated with the uplink transmission repetition (e.g., the uplink communication repetition is to be transmitted using both repetition occasions in the FD set of symbols and the non-FD set of symbols), and a timing offset (e.g., a K2 value) associated with a slot in which the uplink transmission repetition is to begin. For example, the RRC communication and/or the DCI communication may indicate the codepoint “10” to indicate the uplink communication repetition is to be transmitted using both repetition occasions in the FD set of symbols and the non-FD set of symbols regardless of a slot type of a first repetition, and then utilize the K2 value to indicate the slot type of the first transmission.

In some other aspects, the RRC communication and/or the DCI communication may indicate that the uplink transmission repetition is a duplex-specific transmission repetition, such as by using a one-bit bitfield indicating the codepoint “0.” In such aspects, the RRC communication and/or the DCI communication may indicate a timing offset (e.g., a K2 value) associated with a slot in which the uplink transmission repetition is to begin, the slot being associated with one of the FD set of symbols or the non-FD set of symbols (e.g., the K2 value may be used to indicate the duplex type, cither FD or non-FD, associated with the duplex-specific transmission repetition). In some other aspects, the RRC communication and/or the DCI communication may indicate that the uplink transmission repetition is not a duplex-specific transmission repetition, such as by using a one-bit bitfield indicating the codepoint “1.” In such aspects, the RRC communication and/or the DCI communication may indicate a timing offset (e.g., a K2 value) associated with a slot in which the uplink transmission repetition is to begin (e.g., the K2 value may be used to indicate a starting slot for an uplink transmission repetition that spans the FD set of symbols and the non-FD set of symbols).

In some aspects, such as in aspects in which the uplink transmission repetition is associated with a PUSCH repetition, the RRC communication and/or the DCI communication may indicate that the PUSCH repetition is to be transmitted in both the FD set of symbols and the non-FD set of symbols (e.g., by using the codepoint “10,” “11,” or “1,” as described above), and the RRC communication and/or the DCI communication may indicate a first SRI associated with the FD set of symbols (e.g., SRI1described above in connection withFIGS.9A-9F), a first TPMI associated with the FD set of symbols (e.g., TPMI1described above in connection withFIGS.9A-9F), a second SRI associated with the non-FD set of symbols (e.g., SRI2described above in connection withFIGS.9A-9F), and/or a second TPMI associated with the non-FD set of symbols (e.g., TPMI2described above in connection withFIGS.9A-9F).

In some aspects, such as in aspects in which the RRC communication and/or the DCI communication schedules a PUCCH repetition, the RRC communication and/or the DCI communication may indicate (e.g., by using a one-bit bitfield) that the PUCCH repetition is a duplex-specific PUCCH repetition (e.g., by indicating the codepoint “0”). In such aspects, the RRC communication and/or the DCI communication may indicate a timing offset (e.g., a K1 value) associated with a slot in which the PUCCH repetition is to begin, the slot being associated with one of the FD set of symbols or the non-FD set of symbols (e.g., the K1 value may be used to indicate the duplex type, either FD or non-FD, associated with the duplex-specific PUCCH repetition). In some other aspects, the RRC communication and/or the DCI communication may indicate that the PUCCH repetition is not a duplex-specific PUCCH repetition (e.g., by indicating the codepoint “1” in a dedicated one-bit bitfield). In such aspects, the RRC communication and/or the DCI communication may indicate a timing offset (e.g., a K1 value) associated with a slot in which the PUCCH repetition is to begin, the slot being associated with one of the FD set of symbols or the non-FD set of symbols (e.g., the K1 value may be used to indicate a begging slot of the PUCCH repetition).

As shown by reference number1030, the UE120may transmit, and the network node110may receive, the uplink transmission repetition in one of only the FD set of symbols, only the non-FD set of symbols, or both the FD set of symbols and the non-FD set of symbols. For example, in aspects in which the RRC communication and/or the DCI communication indicates that the second SRS resource set or the second group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the non-FD set of symbols) is associated with the uplink transmission repetition (e.g., the uplink communication repetition is to be transmitted using only repetition occasions in the non-FD set of symbols), the UE120may transmit, and the network node110may receive, the uplink transmission repetition (e.g., a PUSCH repetition or a PUCCH repetition) using only the non-FD set of symbols, beginning in a slot associated with the non-FD set of symbols (e.g., as indicated by a K2 parameter or otherwise, as described above in connection with the various codepoints). In aspects in which the RRC communication and/or the DCI communication indicates that the first SRS resource set or the first group of SRS resources (e.g., the SRS resource set or group of SRS resources associated with the FD set of symbols) is associated with the uplink transmission repetition (e.g., the uplink communication repetition is to be transmitted using only repetition occasions in the FD set of symbols), the UE120may transmit, and the network node110may receive, the uplink transmission repetition (e.g., a PUSCH repetition or a PUCCH repetition) using only the FD set of symbols, beginning in a slot associated with the FD set of symbols (e.g., as indicated by a K2 parameter or otherwise, as described above in connection with the various codepoints).

In aspects in which the RRC communication and/or the DCI communication indicates both the first SRS resource set/first group of SRS resources and the second SRS resource set/second group of SRS resources are associated with the uplink transmission repetition (e.g., the uplink communication repetition is to be transmitted using repetition occasions in both the FD set of symbols and the non-FD set of symbols), the UE120may transmit, and the network node110may receive, the uplink transmission repetition (e.g., a PUSCH repetition or a PUCCH repetition) using both the FD set of symbols and the non-FD set of symbols, beginning in a slot indicated by the codepoint, a K2 value, or otherwise, as described above in connection with the various codepoints. Additionally, or alternatively, the UE120may transmit, and the network node110may receive, the uplink transmission repetition (e.g., a PUSCH repetition or a PUCCH repetition) using both the FD set of symbols and the non-FD set of symbols, by applying a frequency offset, such as described above in connection withFIGS.9E and9F. For example, in aspects in which no frequency offset is used, the UE120may transmit, and the network node110may receive, the uplink transmission repetition using a set of frequency resources in the FD set of symbols and using a same set of frequency resources in the non-FD set of symbols. In aspects in which the frequency offset is used, the UE120may transmit, and the network node may receive, the uplink transmission repetition using a first set of frequency resources in the FD set of symbols and using a second set of frequency resources in the non-FD set of symbols, with the first set of frequency resources being separated from the second set of frequency resources by the frequency offset.

Based at least in part on the network node110signaling, to the UE120, SRS resources to be used for an uplink transmission repetition across FD and non-FD sets of symbols, the UE and/or the network node may conserve computing, power, network, and/or communication resources that may have otherwise been consumed traditional uplink transmission repetitions. For example, based at least in part on the network node110signaling, to the UE120, SRS resources to be used for an uplink transmission repetition across FD and non-FD sets of symbols, the UE120and the network node110may communicate with a reduced error rate, which may conserve computing, power, network, and/or communication resources that may have otherwise been consumed to detect and/or correct communication errors.
