Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating that the UE supports performing inter-UE cross-link interference (CLI) measurements in an uplink subband and in at least one downlink subband during one or more overlapping subband full-duplex symbols. The UE may receive, based at least in part on the capability message, a measurement resource configuration for performing the inter-UE CLI measurements in the uplink subband and the at least one downlink subband. The UE may transmit, according to the measurement resource configuration, a measurement report message indicating a measurement result for the inter-UE CLI measurements.

FIELD OF TECHNOLOGY

The following relates to wireless communications, including cross-link interference measurement timing for uplink and downlink subbands.

BACKGROUND

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support cross-link interference (CLI) measurement timing for uplink and downlink subbands. For example, the described techniques provide for various mechanisms to support a user equipment (UE) performing simultaneous CLI measurements in the uplink subband and/or in the downlink subband. One example may include the UE reporting its capability to support inter-UE CLI measurements in both the uplink subband and in the downlink subband during overlapping symbol(s). The UE may transmit a capability message to the network entity indicating the support, such as when the uplink timing and the downlink timing are different. For example, the UE may be equipped with or otherwise support multiple receive chains, where each receive chain performs the inter-UE CLI measurements in separate subbands. In some examples, separate measurement windows (e.g., fast-Fourier transform (FFT)) windows) may be used or otherwise configured for such inter-UE CLI measurements. The UE may receive an indication of a measurement resource configuration for the inter-UE CLI measurements and perform the inter-UE CLI measurements in both the uplink subband and the downlink subband during the overlapping symbol(s), such as overlapping subband full-duplex (SBFD) symbol(s). The UE may transmit a measurement report message to the network entity indicating the results of the inter-UE CLI measurements.

Additionally, or alternatively, the UE may not support simultaneous inter-UE CLI measurements in both the uplink and downlink subbands. The UE may still receive the indication of the measurements resource configuration and, in some examples, perform the inter-UE CLI measurements in the uplink subband and/or in the downlink subband. For example, the UE may use the uplink timing or the downlink timing when measuring the CLI in both the uplink and downlink subbands. In another example, the UE may drop the CLI measurements in the uplink subband or in the downlink subband based on the measurement resource configuration. In some examples, the UE may be subject to a scheduling constraint where the UE does not expect to receive the measurement resource configuration for simultaneous CLI measurements in both the uplink and downlink subbands. In this scenario, an error condition may be detected upon receiving such measurement resource configuration. The error condition may result in the UE not performing the inter-UE CLI measurements due to the error condition. When the UE is able to perform the CLI measurements according to the measurement resource configuration, the UE may again transmit a measurement report message to the network entity indicating the results of the inter-UE CLI measurements.

The method may include transmitting a capability message indicating that the UE supports performing inter-UE CLI measurements in an uplink subband and in at least one downlink subband during one or more overlapping subband full-duplex symbols, receiving, based on the capability message, a measurement resource configuration for performing the inter-UE CLI measurements in the uplink subband and the at least one downlink subband, and transmitting, according to the measurement resource configuration, a measurement report message indicating a measurement result for the inter-UE CLI measurements.

DETAILED DESCRIPTION

Wireless networks may use subband full-duplex (SBFD) symbol(s)/slot(s) where an allocated bandwidth is divided into uplink and downlink subbands. The SBFD allocation enables full-duplex communications between a network entity and one or more user equipment (UE). For example, the network entity may be receiving an uplink transmission from a first UE while, at the same time, transmitting a downlink transmission to a second UE. However, this may introduce cross-link interference (CLI) into the wireless medium, such as inter-UE CLI. To mitigate such inter-UE CLI, CLI measurement and reporting may be scheduled for the victim UE within the bandwidth. Such CLI measurement and reporting may include the UE performing CLI measurements in the uplink subband as well as in the downlink subband (e.g., during overlapping symbol(s)). For example, the uplink timing advance may be different from the downlink timing advance of the UE. Wireless networks conventionally do not provide a mechanism to support a UE being configured with simultaneous CLI measurements in the uplink subband and in the downlink subband.

The described techniques relate to improved methods, systems, devices, and apparatuses that support CLI measurement timing for uplink and downlink subbands. For example, the described techniques provide for various mechanisms to support a UE performing simultaneous CLI measurements in the uplink subband and/or in the downlink subband. One example may include the UE reporting its capability to support inter-UE CLI measurements in both the uplink subband and in the downlink subband during overlapping symbol(s). The UE may transmit a capability message to the network entity indicating the support, such as when the uplink timing and the downlink timing are different. For example, the UE may be equipped with or otherwise support multiple receive chains, such that each receive chain performs the inter-UE CLI measurements in separate subbands. In some examples, separate measurement windows (e.g., fast-Fourier transform (FFT)) windows) may be used or otherwise configured for such inter-UE CLI measurements. The UE may receive an indication of a measurement resource configuration for the inter-UE CLI measurements and perform the inter-UE CLI measurements in both the uplink subband and the downlink subband during the overlapping symbol(s), such as overlapping SBFD symbol(s). The UE may transmit a measurement report message to the network entity indicating the results of the inter-UE CLI measurements.

Additionally, or alternatively, the UE may not support simultaneous inter-UE CLI measurements in both the uplink and downlink subbands. The UE may still receive the indication of the measurements resource configuration and, in some examples, perform the inter-UE CLI measurements in the uplink subband and/or in the downlink subband. For example, the UE may use the uplink timing or the downlink timing when measuring the CLI in both the uplink and downlink subbands. In another example, the UE may drop the CLI measurements in the uplink subband or in the downlink subband based on the measurement resource configuration. In some examples, the UE may be subject to a scheduling constraint where the UE does not expect to receive the measurement resource configuration for simultaneous CLI measurements in both the uplink and downlink subbands. In this scenario, an error condition may be detected upon receiving such measurement resource configuration. The error condition may result in the UE not performing the inter-UE CLI measurements due to the error condition. When the UE is able to perform the CLI measurements according to the measurement resource configuration, the UE may again transmit a measurement report message to the network entity indicating the results of the inter-UE CLI measurements.

Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to cross-link interference measurement timing for uplink and downlink subbands.

A UE115may receive a measurement resource configuration for performing inter-UE CLI measurements during one or more overlapping SBFD symbols and in an uplink subband associated with an uplink timing and in at least one downlink subband associated with a downlink timing that is different from the uplink timing. The UE115may perform, in accordance with the measurement resource configuration, the inter-UE CLI measurements in the uplink subband, in the at least one downlink subband, or both, according to the uplink timing or to the downlink timing to obtain a measurement result.

The network entity105may receive a measurement report message indicating a measurement result for the inter-UE CLI measurements.

For example, the bandwidth allocated to or otherwise associated with communications across the wireless medium are subdivided into different subbands. For example, the UE205and/or the UE210may be associated with a BWP defining the frequency resources (e.g., in the frequency domain and shown along the vertical axis) within which the UE can perform wireless communications. The BWP may be allocated for one or more symbols and/or slots (e.g., in the time domain and shown along the horizontal axis), which may also be referred to as SBFD symbol(s) and/or slot(s). Initially (e.g., during the first few BFD symbol(s)), the frequency resources of the BWP may be allocated for downlink communications220, such as for communicating downlink control channel signals. However, the frequency resources of the BWP may then be divided or otherwise allocated into different subbands for most of the SBFD slot. In the non-limiting example shown inFIG.2, this may include the frequency resources being divided into two downlink subbands (e.g., downlink subband225and downlink subband230) and one uplink subband235. The uplink subband235may be located or otherwise allocated between the two downlink subbands, with gap frequencies between the uplink and downlink subbands. It is to be understood that the SBFD BWP may be divided or otherwise allocated to a different configuration of subbands containing at least one uplink subband and at least one downlink subband. The final period (e.g., the final few symbol(s)) of the SBFD slot) may be allocated for uplink communications (e.g., uplink240), such as for transmitting feedback messages, scheduling requests, or other uplink control channel messages.

Allocating the frequency resources of the BWP into uplink and downlink subbands may support, among other advantages, duplex operations. As one non-limiting example shown inFIG.2, this may enable the network entity215to perform full duplex communications with one or more UEs. For example, the network entity215may be transmitting a downlink signal to the UE210using the downlink subband225and/or downlink subband230while, at the same time, receiving an uplink signal from the UE205using the uplink subband235of the BWP. This may include the network entity215performing full-duplex communications (e.g., transmitting and receiving at the same time) and the UEs (e.g., UE205and/or UE210) performing half-duplex communications (e.g., either transmitting or receiving at a given time).

Such SBFD techniques may also support dynamic enhancements for dynamic/flexible TDD operations within the wireless network. More particularly, such SBFD techniques may increase the uplink duty cycle for wireless communications. This may result in a latency reduction (e.g., it is possible to transmit an uplink signal in uplink subband235during downlink only or flexible slots or receive a downlink signal in downlink subband(s) in legacy uplink only slots). This may improve uplink coverage within the wireless network, enhance system capacity, resource utilization, and spectrum efficiency, and enable flexible and dynamic uplink/downlink resource adaption according to uplink/downlink traffic in a more robust manner.

One concern associated with such SBFD techniques is CLI, which is generally considered the interference introduced or enhanced when a wireless link from one device (e.g., the uplink transmissions from the UE205, in this example) interferes with the wireless link of another device (e.g., the downlink reception at the UE210, in this example). That is, the UE205and the UE210may be located within a proximate threshold range of each other such that the uplink transmission from the UE205has sufficient strength to interference with the ability of the UE210to receive the downlink transmission from the network entity215. The UEs in this example may be located within the same cell (e.g., intra-cell CLI) or may be associated with different cells (e.g., inter-cell CLI). The CLI introduced by such transmissions may also be referred to as inter-UE CLI.

To address inter-UE CLI, different methods may be applied within the wireless communications system200to support inter-UE inter-subband CLI measurements and reporting. One method may include the victim UE (e.g., the UE210, in this example) measuring the reference signal strength indicator (RSSI) within the downlink subband(s). The RSSI may be measured, obtained, or otherwise determined based on the UE210measuring the signal strength of any signal detected within the subband. Another method may include the victim UE measuring the reference signal received power (RSRP) of the aggressor UE (e.g., the UE205, in this example) within the uplink subband (e.g., uplink subband235). Unlike the RSSI that is measured using any signal detected within the subband, the RSSP measurement generally include the aggressor UE transmitting a sounding reference signal (SRS) that is measured by the victim UE. The SRS transmission may involve various messages exchanged between the UEs (e.g., to configure the timing and/or other resources associated with the SRS transmission within the uplink subband). Yet another method may include the victim UE measuring the RSSI within the uplink subband. Again, the RSSI may be measured using any signal within the subband.

Moreover, inter-UE CLI measurements during a SBFD slot according to the first method above may be based, at least to some degree, on whether or not the SBFD slot includes one or two downlink subbands (e.g., how to perform RSSI measurements of two non-contiguous downlink subbands). One technique may include separate CLI-RSSI measurement resources/reports being configured for each downlink subband (e.g., separately for downlink subband225and for downlink subband230). Another technique may include CLI-RSSI measurement/reporting in one of the downlink subbands (e.g., in either downlink subband225or in downlink subband230). Yet another technique may include CLI-RSSI measurement/reporting based on a non-contiguous CLI-RSSI resource across both downlink subbands. That is, this technique monitors the full BWP to determine the CLI-RSSI of a downlink subband.

Accordingly, wireless communications system200may support the victim UE measuring the RSSI or RSRP of the aggressor UE in the uplink subband and/or measuring the RSSI of the aggressor UE within the downlink subband. This may enable the network entity215to configure the victim UE to measure the CLI in the uplink subband235((e.g., for in-band blocking) and within the downlink subband(s) (e.g., for CLI leakage) in the same or in different SBFD symbol(s). When the network entity215configures the UE210to simultaneously measure CLI in the uplink subband and at least one downlink subband in the same SBFD symbol(s), this may be considered a frequency domain multiplexed (FDMed) CLI measurement in the same SBFD symbol(s).

However, uplink communications between the network entity215and UE are based on an uplink timing advance (e.g., uplink timing). The uplink timing generally synchronizes the UE and the network entity215in the time domain based on the uplink channel/propagation path. This may enable configuring time resource allocations for the communications so the UE knows when to transmit an uplink signal and the network entity215knows (e.g., based on the uplink timing advance) when to monitor for the uplink signal. Similarly, downlink communications between the network entity215and UE are based on a downlink timing advance (e.g., downlink timing). The downlink timing again synchronizes the UE and the network entity215in the time domain based on the downlink channel/propagation path. Due to differences between the uplink channel and the downlink channel, the uplink timing and the downlink timing are generally different. That is, the uplink timing advance is not the same as the downlink timing advance. Generally, the uplink timing advance may mean that uplink signals are transmitted before downlink signals (e.g., the uplink timing advance is more than the downlink timing advance, in some examples). This may create difficulties a UE is configured with a measurement resource configuration for inter-UE CLI measurements simultaneously in both the uplink subband and the downlink subband(s).

Accordingly, aspects of the techniques described herein provide various mechanisms to address the victim UE being configured with FDMed simultaneous inter-UE CLI measurements. One example may include the victim UE supporting simultaneous inter-UE CLI measurements in both the uplink subband235and one or both downlink subbands (e.g., downlink subband225and/or downlink subband230).

For example, the UE210(the victim UE, in this example) may transmit or otherwise provide (and the network entity215may receive or otherwise obtain) a capability message indicating that the UE210supports performing inter-UE CLI measurements in an uplink subband and in at least one downlink subband during overlapping SBFD symbol(s). The capability message may be transmitted in a UE capability message, in an assistance information message, or in any uplink control message received by the network entity215.

The capability message may carry or otherwise convey information indicating such support by the UE210using bit(s), field(s), or other information (implicitly and/or explicitly). The UE210may also be an “SBFD aware UE” in that the UE210supports SBFD-based communications where the BWP (e.g., the downlink BWP) has been divided into downlink subband225, downlink subband230, and uplink subband235. Again, the downlink subbands may be separated from the uplink subband235by a guard band (e.g., to prevent subband leakage).

In some examples, this may include the UE210supporting such simultaneous inter-UE CLI measurements in both the uplink subband235and in at least one of the downlink subbands using separate receive chains. For example, the UE210may be equipped with at least two receive chains or paths that enable the UE210to tune one receiver to the uplink subband235and to tune the other receiver to at least one downlink subband. As separate receivers are used, this may enable the UE210to measure the RSSI within the downlink subband using the downlink timing and to measure the RSSI or RSRP within the uplink subband235using the uplink timing. That is, the timing difference between the uplink and downlink timing advances may be mitigated based on the UE210supporting the simultaneous inter-UE CLI measurements. In some examples, different FFT windows (e.g., measurement windows) may be used for the FDMed inter-UE CLI measurements in the uplink and downlink subbands.

Accordingly, the network entity215may transmit or otherwise provide (and the UE210may receive or otherwise obtain) a measurement resource configuration for performing the inter-UE CLI measurements in the uplink subband235and in at least one of the downlink subbands during overlapping SBFD symbol(s). The measurement resource configuration may generally identify, define, or otherwise allocate resources and/or parameters to be applied for performing the inter-UE CLI measurements.

The UE210may perform, according to the measurement resource configuration, the inter-UE CLI measurements during the overlapping SBFD symbol(s) and in the uplink subband235according to the uplink timing and in at least one of the downlink subbands (e.g., in downlink subband225and/or in downlink subband230) according to the downlink timing. The UE210may transmit or otherwise provide (and the network entity215may receive or otherwise obtain) a measurement report message carrying or otherwise conveying an indication of a measurement result for the inter-UE CLI measurements. For example, the measurement result may indicate the RSSI for the at least one downlink subband and the RSSI or RSRP for the uplink subband235. The network entity215may use the measurement report for allocation and scheduling decisions relating to communications with the UE205and/or with the UE210. For example, the inter-UE CLI measurement results may be used to mitigate or otherwise manage the inter-UE CLI associated with performing SBFD-based communications during overlapping and/or adjacent SBFD symbol(s). Accordingly, aspects of the techniques described herein provide for the victim UE to be able to perform FDMed simultaneous inter-UE CLI measurements in both the uplink subband235and at least one of the downlink subbands.

However, in some situations the victim UE may not be able to support or otherwise perform FDMed simultaneous inter-UE CLI measurements in both subbands. That is, the victim UE may be SFBD aware (e.g., support SBFD-based communications) but may not support FDMed simultaneous CLI measurements in the uplink subband and one or more downlink subbands in the same SBFD symbols(s). In some examples, the capability message may indicate that the UE does not support simultaneous inter-UE CLI measurements. In other examples, the capability message may not include an indication of whether the UE supports simultaneous inter-UE CLI measurements. For a UE that does not support simultaneous (e.g., in overlapping SBFD symbol(s)) inter-UE CLI measurements in both uplink and downlink subbands, this may create an issue when scheduled to perform such measurements.

For example, the victim UE (again the UE210, in this example) that does not support inter-UE CLI measurements in the uplink and downlink subbands during overlapping SBFD symbol(s) may still receive the measurement resource configuration for performing the inter-UE CLI measurements during the overlapping symbols. Aspects of the techniques described herein provide further mechanisms to address how the victim UE is to respond (e.g., perform or drop) to such measurement resource configuration when the victim UE doesn't support such simultaneous inter-UE CLI measurements.

In one example, the UE may detect or otherwise declare an error state based on the measurement resource configuration being received. That is, a scheduling constraint applied by the network entity215may limit or restrict the network entity215from configuring the UE with simultaneous inter-UE CLI measurements when the UE does not support such configuration and/or when the network entity215is unaware of the UE supporting such measurements. According to the scheduling constraint, the UE may not expect to receive the measurement resource configuration for performing simultaneous inter-UE CLI measurements in the uplink subband235and at least one of the downlink subbands during the overlapping SBFD symbol(s). However, the victim UE may still receive such a measurement resource configuration (e.g., due to network error, as part of UE-group scheduling, as part of semi-persistent scheduling, or other conditions). Performing the inter-UE CLI measurements in this situation may include the UE not performing the measurements nor transmitting the measurement report. That is, the error case may include the SBFD aware UE not expecting to receive the measurement resource configuration for FDMed simultaneous CLI measurements in the uplink subband235and downlink subband(s) in the same SBFD symbol(s).

In some examples, this may include the victim UE dropping or otherwise disregarding the measurement resource configuration based on the expectation. For example, the UE may disregard, delete, or remove any measurement resource configuration scheduling simultaneous inter-UE CLI measurements in uplink and downlink subbands based on its lack of support for performing such measurements. Accordingly, if an SBFD aware UE receives the measurement resource configuration for the FDMed simultaneous CLI measurements in the uplink subband235and at least one downlink subband in the same SBFD symbol(s), the UE may drop the configuration and not perform the CLI measurements.

In other examples, the victim UE receiving the measurement resource configuration scheduling simultaneous inter-UE CLI measurements may perform the measurements and transmit the measurement report message indicating the results. That is, aspects of the techniques described herein provide for the UE that does not support such simultaneous measurements to perform the inter-UE CLI measurements in accordance with the measurement resource configuration. For example, the UE may perform the inter-UE CLI measurements in the uplink subband235and/or in the at least one downlink subband. The inter-UE CLI measurements may be performed during the overlapping SBFD symbol(s) according to the uplink timing associated with the uplink subband235or according to the downlink timing associated with the at least one downlink subband. The victim UE may transmit the measurement report message to the network entity215that carries or otherwise conveys an indication of the measurement result for the inter-UE CLI measurements.

In some examples, the overlapping SBFD symbol(s) may be identified or otherwise determined based on a periodic pattern. That is, the measurement resource configuration may include one or more measurement instances for inter-UE CLI measurements in the uplink subband and also include one or more measurements instances for the inter-UE CLI measurements in the at least one downlink subband. The periodicity (e.g., a first periodicity) of the measurement instances in the uplink subband may be different from the periodicity (e.g., a second periodicity) of the measurement instances in the at least one downlink subband. The first periodicity may be different from the second periodicity such that some measurement instances for the uplink subband overlap (e.g., partially or fully) with measurement instances for the downlink subband while other measurement instances between the subbands may not overlap. In this situation, the victim UE scheduled to perform simultaneous inter-UE CLI measurements may measure the inter-UE CLI in the uplink subband during an uplink subband measurement instance and then measure the inter-UE CLI in the downlink subband during a subband measurement instance. That is, the UE may use the periodicities of the measurement instances within the SBFD slot for each subband to identify which measurement symbol(s) overlap and which measurement symbol(s) do not overlap. The UE may indicate the measurement results based on this scheme in the measurement report message transmitted to the network entity215.

FIGS.3A and3Bshow examples of a SBFD configuration300that supports CLI measurement timing for uplink and downlink subbands in accordance with one or more aspects of the present disclosure. SBFD configuration300may implement aspects of wireless communications system100and/or aspects of wireless communications system200. Aspects of SBFD configuration300may be implemented at or implemented by a UE and/or a network entity, which may be examples of the corresponding devices described herein. SBFD configuration300-aofFIG.3Ashows an example where the uplink timing of the uplink subband is used for performing simultaneous inter-UE CLI measurements during overlapping SBFD symbol(s). SBFD configuration300-bofFIG.3Bshows an example where the downlink timing of the downlink subband is used for performing simultaneous inter-UE CLI measurements.

As discussed above, aspects of the techniques described herein provide various techniques for a victim UE to measure the inter-UE CLI for an aggressor UE when operating using SBFD based communications. For example, the SBFD communications may include a bandwidth (e.g., such as a downlink BWP) being divided into uplink and downlink subbands. For example, during the initial symbol(s) of the SBFD slot, the full BWP may be allocated to downlink communications305, which may be used to carry downlink control messages, such as grants. The final symbol(s) of the SBFD slot the full BWP may be allocated to uplink communications325, such as uplink control messages. The remaining symbols of the SBFD slot may include the BWP being divided into at least one uplink subband (e.g., uplink subband320) and at least one downlink subband. In the non-limiting example illustrated inFIG.3, the BWP may divided into two downlink subbands (e.g., downlink subband310and downlink subband315). However, it is to be understood that the BWP may be divided into different numbers of uplink and downlink subbands.

The victim UE may receive or otherwise obtain a measurement resource configuration that configures the UE to perform inter-UE CLI measurements during overlapping SBFD symbol(s) in the uplink subband320and in at least one downlink subband (e.g., downlink subband310and/or downlink subband315). However, the uplink subband320may be associated with an uplink timing that is different from the downlink timing that is associated with the at least one downlink subband. Moreover, the UE may not, in some examples, support simultaneous inter-UE CLI measurements in the uplink and downlink subbands. Accordingly, aspects of the techniques described herein provide various mechanisms for the UE to perform the inter-UE CLI measurements in the uplink and/or in the downlink subband(s) during the overlapping SBFD symbol(s) based on the uplink timing or based on the downlink timing.

Turning to SBFD configuration300-aofFIG.3Afirst, this may include the UE using the uplink timing associated with the uplink subband320to perform the inter-UE CLI measurements in the uplink subband320and in the at least one downlink subband during the overlapping SBFD symbol(s). For example, the uplink timing advance for the uplink subband320may be shorter than the downlink timing advance for the at least one downlink subband. This may generally mean that uplink transmissions according to the uplink timing begin before downlink transmissions according to the downlink timing. In this situation, the UE may shift, move, or otherwise switch from the downlink timing to the uplink timing to perform the simultaneous inter-UE CLI measurements in both the uplink subband320and in the at least one downlink subband.

In some examples, this may be based on a timing rule associated with the network entity and/or with the UE. For example, a timing rule may be configured or otherwise established such that the UE and the network entity know that, when configured for simultaneous inter-UE CLI measurements in uplink and downlink subbands, the UE is to apply or otherwise switch from the downlink timing to the uplink timing to perform the CLI measurements in both the uplink subband320and in the at least one downlink subband. The timing rule may be configured by the network entity for the UE, such as using RRC signaling, medium access control-control element (MAC-CE) signaling, or other signaling. In some examples, the timing rule may be defined or otherwise signaled in the measurement resource configuration that configures the simultaneous inter-UE CLI measurements. In some examples, the timing rule may be (pre) configured or otherwise established within the wireless network such that the UE and/or the network entity may be aware of which timing rule is to be applied.

Accordingly, the UE may use the uplink timing to measure or otherwise perform the inter-UE CLI measurements in the uplink subband320and in the at least one downlink subband during the overlapping SBFD symbol(s) according to the measurement resource configuration. For example, the UE may use the uplink timing to measure the RSSI of the at least one downlink subband and to measure the RSSI and/or RSRP in the uplink subband320.

Accordingly, SBFD configuration300-aillustrates a non-limiting example of where a SBFD aware UE that does not support FDMed simultaneous CLI measurement in the uplink subband and in the downlink subband(s) in the same SBFD symbol(s), the same timing may be used for the CLI measurement in uplink subband and downlink subband(s). In this example, the FDMed simultaneous CLI measurement in uplink subband and downlink subband(s) may both be based on the timing. This may include a new rule being established (e.g., the timing rule) where UE autonomously assumes the uplink timing for CLI measurements if the UE receives the measurement resource configuration for the FDMed simultaneous CLI measurement in the uplink subband and the downlink subband(s) in the same SBFD symbol(s). As discussed, then one or two gap symbols may be allocated before the CLI measurement symbol(s) to support switching the downlink timing for the downlink subband(s) reception to the uplink timing. In some aspects, a single FFT window (e.g., measurement window) may be used for the simultaneous inter-UE CLI measurements.

In this example, the victim UE may measure the RSSI within the downlink subband using uplink timing, measure the RSRP of the aggressor UE within the uplink subband using the uplink timing, and/or measure the RSSI within uplink subband using the uplink timing.

Turning to SBFD configuration300-bofFIG.3B, this may include the UE using the downlink timing associated with the at least one downlink subband to perform the inter-UE CLI measurements in the uplink subband320and in the at least one downlink subband during the overlapping SBFD symbol(s). For example, the downlink timing advance for the downlink subband may be longer than the uplink timing advance for the uplink subband. This may generally mean that uplink transmissions according to the uplink timing begin before downlink transmissions according to the downlink timing. In this situation, the UE may shift, move, or otherwise switch from the uplink timing to the downlink timing to perform the simultaneous inter-UE CLI measurements in both the uplink subband320and in the at least one downlink subband.

In some examples, this may be based on the timing rule associated with the network entity and/or with the UE. For example, a timing rule may be configured or otherwise established such that the UE and the network entity know that, when configured for simultaneous inter-UE CLI measurements in uplink and downlink subbands, the UE is to apply or otherwise switch from the uplink timing to the downlink timing to perform the CLI measurements in both the uplink subband320and in the at least one downlink subband.

In some examples, a set of trailing gap symbols may be configured for the UE to switch from the uplink timing to the downlink timing to perform the inter-UE CLI measurements in the uplink subband320and in the at least one downlink subband during the overlapping SBFD symbol(s).

Accordingly, the UE may use the downlink timing to measure or otherwise perform the inter-UE CLI measurements in the uplink subband320and in the at least one downlink subband during the overlapping SBFD symbol(s) according to the measurement resource configuration. For example, the UE may use the downlink timing to measure the RSSI of the at least one downlink subband and to measure the RSSI in the uplink subband320.

Accordingly, SBFD configuration300-billustrates a non-limiting example of where a SBFD aware UE that does not support FDMed simultaneous CLI measurement in the uplink subband and in the downlink subband(s) in the same SBFD symbol(s), the SBFD aware UE that does not support FDMed simultaneous CLI measurement in the uplink subband320and in the at least one downlink subband(s) in the same SBFD symbol(s), the same timing may be used for the CLI measurements in the uplink subband and in the downlink subband(s). This timing rule may indicate that for the FDMed simultaneous CLI measurements in the uplink subband and in the downlink subband(s) may both be based on the downlink timing. That is, in this example the timing rule may indicate that the UE autonomously assumes the downlink timing for CLI measurement if the UE receives the measurement resource configuration of FDMed simultaneous CLI measurement in the uplink subband and in the at least downlink subband(s) in the same SBFD symbol(s). As discussed, the set of trailing gap symbol(s) (e.g., one or two gap symbols, depending on the SCS) after CLI measurement symbol(s) may be configured or otherwise allocated to enable the UE to switch from the downlink timing for the uplink subband back to uplink timing.

In some aspects, the scheduling restriction of one or two gap symbols before the CLI measurement symbol(s) (e.g., the set of preceding gap symbols) may be relaxed or otherwise removed since downlink timing is used for the inter-UE CLI measurements. In some aspects, the single FFT window (e.g., measurement occasion or window) may be used for the reference signal reception and/or CLI measurements. In this example, the UE may measures the RSSI within the at least one downlink subband using the downlink timing and measure the RSSI within uplink subband using the downlink timing.

In some examples, the network entity may instruct the UE which timing to use when performing the inter-UE CLI measurements in the uplink subband and in the at least one downlink subband. For example, the network entity may transmit or otherwise provide (and the UE may receive or otherwise obtain) an indication to use the uplink timing when performing inter-UE CLI measurements in the uplink subband and in the at least one downlink subband (e.g., per SBFD configuration300-a) or to use the downlink timing when performing the inter-UE CLI measurements in the at least one downlink subband (e.g., per SBFD configuration300-b). The indication may be provided, at least to some degree, based on the UE not supporting simultaneous inter-UE CLI measurements in both the uplink subband and in the at least one downlink subband during the overlapping symbols. Accordingly, this feature may enable to the network entity to indicate to the SBFD aware UE that it is to measure the uplink/downlink subband inter-UE CLI using the uplink timing or the downlink timing.

FIGS.4A and4Bshow examples of a SBFD configuration400that supports CLI measurement timing for uplink and downlink subbands in accordance with one or more aspects of the present disclosure. SBFD configuration400may implement aspects of wireless communications system100, aspects of wireless communications system200, and/or aspects of SBFD configuration300. Aspects of SBFD configuration400may be implemented at or implemented by a UE and/or a network entity, which may be examples of the corresponding devices described herein. SBFD configuration400-aofFIG.4Ashows an example where the inter-UE CLI measurements in the downlink subbands are dropped when scheduled to perform simultaneous inter-UE CLI measurements during overlapping SBFD symbol(s). SBFD configuration400-bofFIG.4Bshows an example where the inter-UE CLI measurements in the uplink subband are dropped when scheduled to perform simultaneous inter-UE CLI measurements.

As discussed above, aspects of the techniques described herein provide various techniques for a victim UE to measure the inter-UE CLI for an aggressor UE when operating using SBFD based communications. For example, the SBFD communications may include a bandwidth (e.g., such as a downlink BWP) being divided into uplink and downlink subbands. For example, during the initial symbol(s) of the SBFD slot, the full BWP may be allocated to downlink communications405, which may be used to carry downlink control messages, such as grants. The final symbol(s) of the SBFD slot the full BWP may be allocated to uplink communications425, such as uplink control messages. The remaining symbols of the SBFD slot may include the BWP being divided into at least one uplink subband (e.g., uplink subband420) and at least one downlink subband. In the non-limiting example illustrated inFIG.4, the BWP may divided into two downlink subbands (e.g., downlink subband410and downlink subband415). However, it is to be understood that the BWP may be divided into different numbers of uplink and downlink subbands.

The victim UE may receive or otherwise obtain a measurement resource configuration that configures the UE to perform inter-UE CLI measurements during overlapping SBFD symbol(s) in the uplink subband420and in at least one downlink subband (e.g., downlink subband410and/or downlink subband415). However, the uplink subband420may be associated with an uplink timing that is different from the downlink timing that is associated with the at least one downlink subband. Moreover, the UE may not, in some examples, support simultaneous inter-UE CLI measurements in the uplink and downlink subbands. Accordingly, aspects of the techniques described herein provide various mechanisms for the UE to perform the inter-UE CLI measurements in the uplink and/or in the downlink subband(s) during the overlapping SBFD symbol(s) based on the uplink timing or based on the downlink timing.

Turning to SBFD configuration400-aofFIG.4Afirst, this may include the UE dropping the inter-UE CLI measurements in the at least one downlink subband (e.g., the UE may not perform the inter-UE CLI measurements in the at least downlink subband). Instead, the UE may perform the inter-UE CLI measurements in the uplink subband according to the uplink timing. For example, the UE may use the uplink timing to measure or otherwise determine the RSRP and/or the RSSI of the uplink subband420during the overlapping SBFD symbol(s) and skip, drop, or otherwise not perform the RSSI of the at least one downlink subband.

Accordingly, SBFD configuration400-aillustrates a non-limiting example where a SBFD aware UE that does not support FDMed simultaneous CLI measurement in the uplink subband and in the at lest one downlink subband(s) in the same SBFD symbol(s), the same timing may be used for performing the CLI measurements in the uplink subband and the at least one downlink subband(s). In this example, the UE maintains the inter-UE CLI measurement in the uplink subband and drops the inter-UE CLI measurement in the downlink subband(s).

In some examples, this may be based on a rule, such as the timing rule or a different rule (e.g., a dropping rule) that is known by the network entity and the UE. The rule may indicate or otherwise identify which inter-UE CLI measurements are performed and/or which inter-UE CLI measurements are dropped. The rule may be signaled, such as using RRC signaling, MAC-CE signaling, and/or signaled in the measurement resource configuration. The rule may be (pre) configured within the wireless network, in some example. Broadly, the new rule may include the UE autonomously dropping the CLI measurements in the downlink subband(s) if the UE receives the measurement resource configuration for FDMed simultaneous CLI measurement in the uplink subband and the downlink subband(s) in the same SBFD symbol(s). In this example of the rule where the downlink subband CLI measurements are dropped, the uplink timing will be used for performing the inter-UE CLI measurements in the uplink subband. In some examples, a single FFT window (e.g., measurement window) may be allocated or otherwise configured for the reception/measurement of the CLI. In this example, the UE may measure or otherwise determine the RSRP of the aggressor UE within uplink subband using uplink timing and/or may measure the RSSI within the uplink subband using the uplink timing.

Turning next to SBFD configuration400-bofFIG.4B, this may include the UE dropping the inter-UE CLI measurements in the uplink subband (e.g., the UE may not perform the inter-UE CLI measurements in the uplink subband). Instead, the UE may perform the inter-UE CLI measurements in the at least one downlink subband according to the downlink timing. For example, the UE may use the downlink timing to measure or otherwise determine the RSSI of the downlink subband(s) during the overlapping SBFD symbol(s) and skip, drop, or otherwise not perform the RSSI and/or RSRP measurement within the uplink subband.

Accordingly, SBFD configuration400-billustrates a non-limiting example where a SBFD aware UE that does not support FDMed simultaneous CLI measurements in the uplink subband and the downlink subband(s) in the same SBFD symbol(s) where the same timing may be used for the CLI measurements. This may include maintaining the inter-UE CLI measurement in the downlink subband(s) and dropping, skipping, or otherwise not performing the CLI measurement in the uplink subband.

Again, this may be based on a new rule (e.g., timing rule or dropping rule) where the UE autonomously drops the CLI measurement in the uplink subband if the UE receives the measurement resource configuration of FDMed simultaneous CLI measurements in the uplink subband and in the downlink subband(s) in the same SBFD symbol(s). In this situation, the downlink timing may be used to perform the inter-UE CLI measurements in the downlink subband(s). Again, in some examples a single FFT window (e.g., measurement window) may be scheduled or otherwise used for the reception and/or measurements associated with the inter-UE CLI measurements. One non-limiting example of application of this rule may include the use case where the timing is off between downlink and uplink subbands (e.g., the downlink timing is different from the uplink timing). In this case, the UE may measure the RSSI in the downlink subband. That is, the UE may measure the RSSI within the at least one downlink subband using the downlink timing.

In some examples, the network entity may instruct the UE which CLI measurement to drop and/or to perform. For example, the network entity may transmit or otherwise provide (and the UE may receive or otherwise obtain) an indication to drop the inter-UE CLI measurements in the uplink subband (e.g., per SBFD configuration400-a) or in the at least one downlink subband (e.g., per SBFD configuration400-b). The indication may be provided, at least to some degree, on the UE not supporting simultaneous inter-UE CLI measurements in both the uplink subband and in the at least one downlink subband during the overlapping symbols. Accordingly, this feature may enable to the network entity to indicate to the SBFD aware UE that it is to measure the uplink/downlink subband inter-UE CLI and drop the downlink/uplink subband inter-UE CLI measurement.

SBFD configuration400-balso illustrates an example of the periodicity of the measurement occasions or instances in the uplink subband and in the downlink subband(s) being used to identify or otherwise determine the overlapping SBFD symbol(s). As shown, the first periodicity of CLI measurements in the uplink subband may be different from the second periodicity of the CLI measurements in the downlink subband. This may result in some uplink subband measurement instances overlapping (e.g., in the time domain) with one or more downlink subband measurement instances (with two overlapping instances being shown by way of example only). In this example, the UE may drop the first and third uplink subband CLI measurement instances and, instead, measure the CLI in the downlink subband(s) using the downlink timing. The UE may measure the inter-UE CLI in the uplink subband using the uplink timing during the uplink subband measurement instance that does not overlap in the time domain with a downlink subband measurement instance (with one non-overlapping uplink subband measurement instance being shown by way of example only). The UE may use the periodicities of the measurement instances in the uplink and downlink subbands to identify or otherwise determine the overlapping SBFD symbol(s).
