Patent Description:
<CIT> relates to a device for determining a repetition number of a physical data channel under coverage enhancement.

The invention is defined in independent claims <NUM>, <NUM> and <NUM>. In the following, each of the described methods, apparatuses, examples, and aspects which does not fully correspond to the invention as defined in the claims is thus not according to the invention and is, as well as the whole following description, present for illustration purposes only or to highlight specific aspects or features of the claims.

Some UEs may be considered Internet-of Things (IoT) devices, and/or may be implemented as may be implemented as NB-IoT (narrowband internet of things) devices.

Other examples may differ from what was described with regard to <FIG>.

Controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, and/or any other component(s) of <FIG> may perform one or more techniques associated with transport block transmission using different spatial parameters, as described in more detail elsewhere herein. For example, controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, and/or any other component(s) of <FIG> may perform or direct operations of, for example, process <NUM> of <FIG>, process <NUM> of <FIG>, process <NUM> of <FIG>, process <NUM> of <FIG>, process <NUM> of <FIG>, and/or other processes as described herein. Memories <NUM> and <NUM> may store data and program codes for base station <NUM> and UE <NUM>, respectively.

In some aspects, UE <NUM> and/or base station <NUM> may include means for determining a first set of parameters associated with a first transport block (TB) repetition of a TB and a second set of parameters associated with a second TB repetition of the TB; means for determining a TB size of the TB based at least in part on the first set of parameters, the second set of parameters, or both the first set of parameters and the second set of parameters; and/or the like. In some aspects, such means may include one or more components of UE <NUM> and/or base station <NUM> described in connection with <FIG>.

In some aspects, UE <NUM> may include means for receiving a grant for a first TB repetition, wherein the grant indicates a first mini-slot in which the first TB repetition is scheduled; means for determining one or more subsequent mini-slots, that occur after the first mini slot, in which one or more subsequent TB repetitions are scheduled based at least in part on a mini-slot pattern configuration or one or more parameters of the first TB repetition; and/or the like. Additionally, or alternatively, UE <NUM> may include means for receiving an indication of a first set of symbols and a second set of symbols in which a single communication is scheduled; means for transmitting or receiving the single communication in the first set of symbols and the second set of symbols using a first spatial parameter for the first set of symbols and a second spatial parameter for the second set of symbols; and/or the like. In some aspects, such means may include one or more components of UE <NUM> described in connection with <FIG>.

In some aspects, base station <NUM> may include means for transmitting a grant for a first TB repetition, wherein the grant indicates a first mini-slot in which the first TB repetition is scheduled; means for scheduling one or more subsequent TB repetitions in one or more subsequent mini-slots that occur after the first mini slot, wherein the one or more subsequent mini-slots are determined based at least in part on a mini-slot pattern configuration or one or more parameters of the first TB repetition; and/or the like. Additionally, or alternatively, base station <NUM> may include means for transmitting an indication of a first set of symbols and a second set of symbols in which a single communication is scheduled; means for transmitting or receiving the single communication in the first set of symbols and the second set of symbols using a first spatial parameter for the first set of symbols and a second spatial parameter for the second set of symbols; and/or the like. In some aspects, such means may include one or more components of base station <NUM> described in connection with <FIG>.

<FIG> shows an example frame structure <NUM> in a telecommunications system (e.g., NR). Each subframe may have a predetermined duration (e.g., <NUM>) and may include a set of slots (e.g., <NUM>m slots per subframe are shown in <FIG>, where m is a numerology used for a transmission, such as <NUM>, <NUM>,<NUM>, <NUM>, <NUM>, and/or the like). In some aspects, a slot may include one or more mini-slots. A mini-slot may include a number of symbols (e.g., <NUM> symbols, <NUM> symbols, <NUM> symbols, and/or the like) capable of being scheduled as a unit. In some aspects, a scheduling unit may be frame-based, subframe-based, slot-based, mini-slot based, symbol-based, and/or the like.

In some aspects, transmissions may be repeated in multiple transmission time intervals (TTIs), such as multiple slots, multiple mini-slots, multiple sets of symbols, and/or the like, such as for multi-slot transmission and/or slot aggregation (e.g., on a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), and/or the like). In some aspects, one, two, four, or eight repetitions may be used in a time period (P). Additionally, or alternatively, different repetitions may use different redundancy versions of a communication. In some aspects, such repetition schemes may be used to achieve higher reliability and/or lower latency, such as for ultra-reliable low latency communication (URLLC), uplink grant-free communication, and/or the like.

While some techniques are described herein in connection with frames, subframes, slots, min-slots, and/or the like, these techniques may equally apply to other types of wireless communication structures or transmission time intervals (TTIs), which may be referred to using terms other than "frame," "subframe," "slot," "mini-slot," and/or the like in <NUM> NR. In some aspects, a wireless communication structure or a TTI may refer to a periodic time-bounded communication unit defined by a wireless communication standard and/or protocol. Additionally, or alternatively, different configurations of wireless communication structures and/or TTIs than those shown in <FIG> may be used.

Other examples may differ from what was described with regard to <FIG>.

The available time frequency resources may be partitioned into resource blocks (RBs). Each resource block may cover a set to of subcarriers (e.g., <NUM> subcarriers) in one slot and may include a number of resource elements.

The ANC <NUM> may be a central unit (CU) of the distributed RAN <NUM>. The backhaul interface to the next generation core network (NG-CN) <NUM> may terminate at the ANC <NUM>. The backhaul interface to neighboring next generation access nodes (NG-ANs) may terminate at the ANC <NUM>. The ANC <NUM> may include one or more TRPs <NUM> (which may also be referred to as BSs, NR BSs, Node Bs, <NUM> NBs, APs, gNB, or some other term). As described above, a TRP <NUM> may be used interchangeably with "cell. " In some aspects, multiple TRPs <NUM> may be included in a single base station <NUM>. Additionally, or alternatively, different TRPs <NUM> may be included in different base stations <NUM>.

A TRP <NUM> may be a distributed unit (DU). A TRP <NUM> may be connected to a single ANC <NUM> or multiple ANCs <NUM>. For example, for RAN sharing, radio as a service (RaaS), and service specific AND deployments, the TRP <NUM> may be connected to more than one ANC <NUM>. A TRP <NUM> may include one or more antenna ports. The TRPs <NUM> may be configured to individually (e.g., using dynamic selection) or jointly (e.g., using joint transmission) serve traffic to a UE <NUM>.

In some aspects, multiple TRPs <NUM> may transmit the same communication (e.g., the same transport block, PDSCH communication, and/or the like) in different TTIs (e.g., slots, mini-slots, and/or the like) using different spatial parameters (e.g., different quasi co-location (QCL) parameters, different transmission configuration indicator (TCI) states, different precoding parameters, different beamforming parameters, and/or the like). Additionally, or alternatively, a UE <NUM> may transmit the same communication (e.g., the same transport block, PUSCH communication, PUCCH communication, and/or the like) in different TTIs using different spatial parameters (e.g., different spatial domain filters, different spatial relations, different precoding parameters, different beamforming parameters, and/or the like), such as when the UE <NUM> is transmitting to different TRPs <NUM>.

The architecture may be defined to support fronthauling solutions across different deployment types. The NG-AN <NUM> may share a common fronthaul for LTE and NR. For example, cooperation may be preset within a TRP <NUM> and/or across TRPs <NUM> via the ANC <NUM>. In some aspects, no inter-TRP interface may be needed/present.

In some aspects, a dynamic configuration of split logical functions may be present within the architecture of RAN <NUM>. The packet data convergence protocol (PDCP), radio link control (RLC), media access control (MAC) protocol, and/or the like may be adaptably placed at the ANC <NUM> or TRP <NUM>. According to various aspects, a base station <NUM> may include a central unit (CU) (e.g., ANC <NUM>) and/or one or more distributed units (e.g., one or more TRPs <NUM>).

<FIG> is a diagram illustrating an example <NUM> of transport block transmission using different spatial parameters, in accordance with various aspects of the present disclosure.

As shown in <FIG>, a transmitter <NUM> and a receiver <NUM> may communicate with one another in a wireless communication system. The transmitter <NUM> and/or the receiver <NUM> may be a wireless communication device, such as a base station <NUM>, a UE <NUM>, and/or the like. In some aspects, the transmitter <NUM> is a base station <NUM> and the receiver <NUM> is a UE <NUM>. In some aspects, the transmitter <NUM> is a UE <NUM> and the receiver <NUM> is a base station <NUM>.

Transport blocks (TBs) transmitted in different TTIs (e.g., slots, mini-slots, sets of symbols, and/or the like) may be associated with different parameters used to determine respective transport block (TB) sizes of those TBs. In some aspects, a parameter used to determine a size of a TB may be referred to as a TB size determination parameter, and may include, for example, a modulation and coding scheme (MCS) used for the TB, a number of resource elements allocated for the TB, a number of layers (e.g., spatial layers) to be used to transmit the TB, and/or the like. When different TBs are transmitted in different TTIs and/or by different base stations <NUM> and/or TRPs <NUM> (e.g., in different RBs and/or different spatial layers), those TBs may have different TB sizes if those TBs are associated with different TB size determination parameters.

However, when a TB is repeated in multiple TTIs, in different RBs, and/or in different spatial layers, that TB must have the same size across all repetitions because the same TB is included in each repetition (with potentially different redundancy versions). If a TB size were to be determined independently for each TB repetition, then different TB sizes may be determined for different TB repetitions, which would violate the requirement that the TB in each repetition be the same size. For example, demodulation reference signal (DMRS) sharing may be used across TB repetitions, where only some of the TB repetitions include DMRS to reduce DMRS overhead. In this case, different TB repetitions would include different numbers of symbols (e.g., resource elements), which would lead to different TB sizes.

As another example, in the case where different TB repetitions are transmitted by different TRPs, those TRPs may be permitted to flexibly schedule respective TB repetitions (e.g., using a different number of symbols or different mini-slot sizes), thereby resulting in different numbers of symbols for different TB repetitions, which would lead to different TB sizes. Similarly, different TB repetitions may be scheduled using a different number of symbols and/or different mini-slot sizes to avoid crossing a slot boundary for a particular TB repetition. Furthermore, different TRPs may have different channel conditions in relation to a UE <NUM> (e.g., particularly when the TRPs are not co-located within the same base station <NUM>), which may lead to different MCS parameters, different numbers of spatial layers, and/or the like being used by the different TRPs for respective TB repetitions, which would lead to different TB sizes.

As indicated above, if a TB size for each TB repetition, of a set of TB repetitions (e.g., an initial TB repetition and one or more other TB repetitions, which may be subsequent to the initial TB repetition or transmitted using a different set of RBs and/or a different set of spatial layers), is determined independently for each TB repetition, then the transmitter <NUM> and/or the receiver <NUM> may determine different TB sizes for different TB repetitions, which would prevent the same TB from being repeated. Some techniques and apparatuses described herein permit the transmitter <NUM> and the receiver <NUM> to determine TB sizes for TB repetitions such that all TB repetitions have the same size, thereby enabling TB repetitions. Furthermore, the transmitter <NUM> and the receiver <NUM> may apply the same technique or rule for TB size determination, thereby reducing ambiguity and resulting in fewer communication errors. Additional details are described below.

As shown by reference number <NUM>, a first TB repetition (shown as TB repetition <NUM>) may be scheduled in a first TTI (e.g., a first slot, a first mini-slot, a first set of symbols, and/or the like), and is associated with a first set of TB size determination parameters. As shown, the first set of TB size determination parameters includes a first MCS, a first number of resource elements (REs), a first number of layers (e.g., MIMO layers, spatial layers, and/or the like), and/or the like. As used herein, the term "repetition" may refer to a communication that is transmitted more than one time, and includes the initial transmission of that communication as well as each subsequent transmission of that communication. In some aspects, such repetitions may be transmitted without using hybrid automatic repeat request (HARQ) feedback.

As shown by reference number <NUM>, a second TB repetition (shown as TB repetition <NUM>) may be scheduled in a second TTI (e.g., a second slot, a second mini-slot, a second set of symbols, and/or the like), and is associated with a second set of TB size determination parameters. As shown, the second set of TB size determination parameters includes a second MCS, a second number of REs, a second number of spatial layers, and/or the like. As shown, the first TB repetition and the second TB repetition may be scheduled in, transmitted in, and/or received in different TTIs (e.g., in the case of time-division multiplexing (TDM)). Additionally, or alternatively, the first TB repetition and the second TB repetition may be scheduled in, transmitted in, and/or received in different sets of REs and/or RBs (e.g., in the case of frequency-division multiplexing (FDM)). Additionally, or alternatively, the first TB repetition and the second TB repetition may be scheduled in, transmitted in, and/or received in different spatial layers (e.g., in the case of spatial-division multiplexing (SDM)). In some aspects, the first TB and the second TB may be transmitted in the same TTI but with different parameters, as shown (e.g., different spatial layers, different numbers of REs, different RBs, and/or the like). Although two TB repetitions are shown as an example, a different number of TB repetitions may be used (e.g., four, eight, and/or the like). In some aspects, sets of TB size determination parameters may be indicated in a radio resource control (RRC) message, in downlink control information (DCI), and/or the like.

As shown by reference number <NUM>, the transmitter <NUM> determines a TB size for a repeated TB using a rule. Similarly, as shown by reference number <NUM>, the receiver <NUM> determines the TB size for the repeated TB using the rule. The rule is a common rule that is commonly applied by both the transmitter <NUM> and the receiver <NUM>, thereby reducing ambiguity and reducing communication errors. Application of the rule results in a determination of a same TB size for multiple TB repetitions, even if those TB repetitions are associated with different TB size determination parameters. In some aspects, the rule may be pre-specified according to a wireless communication standard. Additionally, or alternatively, the rule may be pre-configured according to a configuration message communicated between the transmitter <NUM> and the receiver <NUM> (e.g., in an RRC message and/or the like).

In some aspects, the rule may be based at least in part on the first set of TB size determination parameters and/or the second set of TB size determination parameters (and/or or one or more other sets of TB size determination parameters for one or more other TB repetitions). In this case, the transmitter <NUM> and the receiver <NUM> may determine the TB size for the multiple TB repetitions based at least in part on one or more sets of TB size determination parameters of multiple sets of TB size determination parameters corresponding to the multiple TB repetitions.

In some aspects, only the first set of TB size determination parameters, associated with the first TB repetition (e.g., an initial TB repetition), may be used to determine the TB size. For example, a pre-specified and/or pre-configured rule may indicate that the TB size for all TB repetitions is to be determined using TB size determination parameters of only the initial TB repetition. This may conserve resources (e.g., processing resources, memory resources, and/or the like) by reducing or eliminating calculations using other sets of TB size determination parameters.

In some aspects, the TB size is determined based at least in part on a function of a first TB size determined using the first set of TB size determination parameters and a second TB size determined using the second set of TB size determination parameters (and or one or more other TB sizes determined using one or more other sets of TB size determination parameters associated with one or more other TB repetitions). For example, TB sizes are calculated for each TB repetition (e.g., using corresponding TB size determination parameters), and a function is applied to those calculated TB sizes to determine a common TB size to be used for all TB repetitions. The function includes a minimum TB size of the calculated TB sizes, a maximum TB size of the calculated TB sizes, an average TB size of the TB sizes, and/or the like. In this way, the TB repetitions may be flexibly configured to account for different scenarios, such as different network conditions (e.g., traffic load and/or the like), different channel conditions, and/or the like.

In some aspects, the TB size may be determined using only a single set of TB size determination parameters corresponding to a specific TB repetition. In some aspects, a base station <NUM> may indicate the specific TB repetition to a UE <NUM> (e.g., in DCI, in an RRC message, and/or the like). Additionally, or alternatively, the specific TB repetition may be a TB repetition associated with a specific spatial parameter (e.g., QCL parameter, TCI state, spatial domain filter, and/or the like). The specific spatial parameter may be a spatial parameter that satisfies a condition, such as a spatial parameter with the lowest value among all spatial parameters for all TB repetitions, a spatial parameter with the highest value among all spatial parameters for all TB repetitions, a spatial parameter that matches a default value, and/or the like. In some aspects, the specific spatial parameter may be pre-specified in a wireless communication standard, may be pre-configured in a configuration message, may be communicated between the transmitter <NUM> and the receiver <NUM>, and/or the like.

In some aspects, the TB size may be determined based at least in part on a joint determination that is a function of the first set of TB size determination parameters and the second set of TB size determination parameters (and one or more other sets of TB size determination parameters associated with one or more other TB repetitions). In this case, the TB size may be determined as a function of all of the TB size determination parameters of all TB repetitions, without first calculating individual TB sizes for each TB repetition.

As shown by reference number <NUM>, the transmitter <NUM> or the receiver <NUM> may transmit, to the other of the transmitter <NUM> or the receiver <NUM>, the rule to be applied to determine the TB size for the multiple TB repetitions. For example, a base station <NUM> may transmit, and a UE <NUM> may receive, an indication of the rule. As indicated above, in some aspects, the indication may identify a specific TB repetition, and the set of TB size determination parameters corresponding to that TB repetition may be used to determine the TB size for all TB repetitions. Alternatively, one or more other rules may be indicated, as described above. In some aspects, the rule may be indicated in an RRC message (e.g., an RRC configuration message, an RRC reconfiguration message, and/or the like), in DCI, and/or the like.

In some aspects, when the transmitter <NUM> is a UE <NUM>, the TB repetitions may be scheduled and/or transmitted in the PUSCH. In some aspects, when the transmitter <NUM> is a base station <NUM>, the TB repetitions may be scheduled and/or transmitted n the PDSCH. In some aspects, different base stations <NUM> and/or TRPs <NUM> may schedule and/or transmit different TB repetitions. In all of these cases, the UE <NUM> and the base station <NUM> (and/or the TRPs <NUM>) may both apply the same rule when determining a TB size for TB repetitions, thereby enabling TB repetition that uses the same TB size across all repetitions, reducing ambiguity, and reducing communication errors.

Other examples may differ from what was described with respect to <FIG>.

<FIG> is a diagram illustrating another example <NUM> of transport block transmission using different spatial parameters, in accordance with various aspects of the present disclosure.

As described above, a TB may be repeated in multiple mini-slots. However, this may consume additional control resources (e.g., on a physical downlink control channel (PDCCH)) if a grant were to be transmitted for each TB repetition (e.g., with control information for the TB repetition, such as a resource allocation and/or other TB parameters). Some techniques and apparatuses described herein permit a single grant (e.g., a downlink grant) to be used to schedule multiple TB repetitions, thereby conserving network resources and device resources (e.g., processing resources, memory resources, battery power, and/or the like) that would otherwise be consumed to transmit and/or process multiple grants corresponding to the multiple TB repetitions. In some aspects, additional resources may be conserved by using control information for a single TB repetition (e.g., the first or initial TB repetition) to determine control information for other (e.g., subsequent) TB repetitions (e.g., according to a configuration, which may be transmitted once, in an RRC message, instead of multiple times in DCI). Additional details are described below.

As shown by reference number <NUM>, a base station <NUM> may transmit, and a UE <NUM> may receive, a mini-slot pattern configuration to be used for TB repetition. The mini-slot pattern configuration may indicate a pattern of mini-slots (e.g., in a time domain) for a time period. In some aspects, the time period may be indicated in the mini-slot pattern configuration. Additionally, or alternatively, the time period may be pre-specified according to a wireless communication standard. The time period may include, for example, a number of slots (e.g., <NUM> slot, <NUM> slots, <NUM> slots, and/or the like), a number of symbols (e.g., <NUM> symbols, <NUM> symbols, <NUM> symbols, <NUM> symbols, <NUM> symbols, <NUM> symbols, and/or the like), and/or the like. In some aspects, the time period may depend on whether slots are configured with a normal cyclic prefix (e.g., with <NUM> symbols) or an extended cyclic prefix (e.g., with <NUM> symbols). In some aspects, the mini-slot pattern configuration may be indicated in an RRC message.

A mini-slot pattern configuration may indicate a number of mini-slots included in the time period and the symbols occupied by each of the mini-slots. In some aspects, the mini-slot pattern configuration may indicate the set of symbols occupied by a mini-slot by indicating a starting symbol and an ending symbol of the mini-slot. Additionally, or alternatively, the mini-slot pattern configuration may indicate the set of symbols occupied by a mini-slot by indicating a starting symbol and a duration (e.g., a length, a number of symbols, and/or the like) of the mini-slot. In some aspects, the mini-slot pattern may be configured such that none of the individual mini-slots, indicated in the mini-slot pattern, cross a slot boundary, thereby reducing complexity (e.g., since processing by the UE <NUM> and/or the base station <NUM> may be slot-based). In other words, each mini-slot, included in the mini-slot pattern, may be self-contained within a single slot.

For example, as shown by reference number <NUM>, a mini-slot pattern configuration may be indicated for a time period of two slots, where each slot includes <NUM> symbols (e.g., with an extended cyclic prefix). The mini-slot pattern configuration may indicate that a first mini-slot (shown as Mini slot <NUM>) occupies symbols <NUM> and <NUM> of the first slot, that a second mini-slot (shown as Mini slot <NUM>) occupies symbols <NUM> and <NUM> of the first slot, that a third mini-slot (shown as Mini slot <NUM>) occupies symbols <NUM>, <NUM>, and <NUM> of the first slot, that a fourth mini-slot (shown as Mini slot <NUM>) occupies symbols <NUM> and <NUM> of the second slot, and so on. Thus, as shown, different mini-slots in the mini-slot pattern configuration may be configured with different lengths (e.g., <NUM> symbols, <NUM> symbols, <NUM> symbols, and/or the like). Alternatively, in some aspects, all of the mini-slots of a specific mini-slot pattern may have the same length.

As shown by reference number <NUM>, the base station <NUM> may transmit, and the UE <NUM> may receive, a grant (e.g., DCI) for a first TB repetition (e.g., an initial TB repetition). The grant may indicate a first mini-slot (e.g., a first set of symbols) in which the first TB repetition is scheduled. In example <NUM>, the grant is scheduled, transmitted, and received in symbol <NUM> of the first slot (e.g., in the PDCCH), and indicates that the first TB repetition occurs in symbols <NUM>, <NUM>, and <NUM> of the first slot (e.g., in the PDSCH or the PUSCH), as shown by reference number <NUM>. As shown, the mini-slot in which the first TB repetition is scheduled, transmitted, and/or received does not need to be included in the mini-slot pattern indicated by the mini-slot pattern configuration. However, in some aspects, the mini-slot in which the first TB repetition is scheduled, transmitted, and/or received may be included in the mini-slot pattern.

As shown by reference number <NUM>, one or more subsequent TB repetitions, that occur after the first TB repetition, may be scheduled, transmitted, and/or received based at least in part on the mini-slot pattern configuration. For example, one or more subsequent mini-slots, corresponding to the one or more subsequent TB repetitions, may occur after the first mini-slot in which the first TB repetition is scheduled. In some aspects, the number of subsequent mini-slots may be determined based at least in part on a number of TB repetitions (e.g., an aggregation level, which may be indicated in the grant), and the symbols occupied by those TB repetitions may be determined based at least in part on the mini-slot pattern. In some aspects, the mini-slot(s) for the subsequent TB repetition(s) may have a starting symbol that occurs after an ending symbol of the first mini-slot in which the first TB repetition is scheduled.

For example, in example <NUM>, the first TB repetition is scheduled in a first mini-slot that ends in symbol <NUM> of the first slot. In this case, Mini slot <NUM> and Mini slot <NUM> cannot be subsequent mini-slots because Mini slot <NUM> occurs entirely before the first TB repetition and Mini slot <NUM> overlaps with the first TB repetition. In other words, Mini slot <NUM> and Mini slot <NUM> do not start after an ending symbol of the first TB repetition (e.g., symbol <NUM> of the first slot). However, Mini slot <NUM> and Mini slot <NUM> can be subsequent mini-slots because both Mini slot <NUM> and Mini slot <NUM> start after the end of the first TB repetition. In this case, if the number of repetitions is two, then the TB would be repeated in the scheduled mini-slot (e.g., symbols <NUM>, <NUM>, and <NUM> of the first slot) and Mini slot <NUM> (e.g., symbols <NUM>, <NUM>, and <NUM> of the first slot). If the number of repetitions is greater than two, then the TB would be repeated in the scheduled mini-slot (e.g., symbols <NUM>, <NUM>, and <NUM> of the first slot), Mini slot <NUM> (e.g., symbols <NUM>, <NUM>, and <NUM> of the first slot), Mini slot <NUM> (e.g., symbols <NUM> and <NUM> of the second slot), and potentially one or more other mini-slots include in the mini-slot pattern, depending on the number of repetitions.

Additionally, or alternatively, the one or more subsequent TB repetitions, that occur after the first TB repetition, may be scheduled, transmitted, and/or received based at least in part on one or more parameters of the first TB repetition, such as a starting symbol of the first TB repetition, a length of the first TB repetition, an ending symbol of the first TB repetition, a time domain resource allocation of the first TB repetition, and/or the like. For example, the grant for the first TB repetition may schedule multiple (e.g., two, three, or more) contiguous TB repetitions. In some aspects, the grant may indicate a length of the first TB repetition and a starting symbol for the first TB repetition. In this case, the UE <NUM> may infer the starting symbol of the second TB repetition using the length of the first repetition and the starting symbol of the first TB repetition. For example, starting symbol of the first repetition plus the length of the first TB repetition may indicate the end of the first TB repetition. The UE <NUM> may determine that the second TB repetition occurs in a next consecutive symbol after the end of the first TB repetition.

In some aspects, one or more parameters (e.g., sometimes referred to herein as TB parameters) for the first TB repetition may be used for one or more subsequent TB repetitions. This may conserve network resources and control information overhead by reusing a set of TB parameters, indicated in the grant, for multiple TB repetitions. For example, a TB parameter may include an MCS, a frequency domain allocation (e.g., frequency resources in which the TB repetitions are scheduled), and/or the like, which may be indicated once (e.g., in the grant) and used for multiple TB repetitions.

In some aspects, some parameters may differ between the first TB repetition and one of more subsequent TB repetitions, such as a spatial parameter (e.g., a TCI state, a QCL parameter, a spatial domain filter, and/or the like), a redundancy version, and/or the like. In this case, the parameters that differ across TB repetitions may be indicated in the grant, in an RRC message, and/or the like. In some aspects, if a parameter is not indicated for a subsequent TB repetition (e.g., in the grant, in DCI, in an RRC message, and/or the like), then the UE <NUM> may determine that the parameter is the same for the first TB repetition and the subsequent TB repetition.

In some aspects, the grant may indicate a redundancy version (RV) for a TB repetition other than the first TB repetition. For example, the grant may explicitly indicate the redundancy version using a redundancy version identifier. Alternatively, the grant may indicate a redundancy version offset. In this case, the UE <NUM> may determine a redundancy version for a subsequent TB repetition (e.g., a second TB repetition) by applying the redundancy version offset to a redundancy version of a prior TB repetition (e.g., the first TB repetition). In some aspects, the redundancy version offset may wrap around (e.g., from RV0, RV1, RV2, RV3, back to RV0 in the case of four redundancy versions). In some aspects, the RV offset may be indicated in an RRC message.

In some aspects, DCI may indicate whether to operate in a single TRP transmission mode or a multi-TRP transmission mode, to permit dynamic switching between these modes. For example, an index value in a field of DCI (e.g., a TCI index value in a TCI field) may be used in association with a table stored in memory. The table may indicate a number of TRPs (e.g., a number of spatial parameters) and the spatial parameter value(s) to be used for those TRPs. In some aspects, only the index value (e.g., the TCI index value) may be used to determine the number of TRPs and the spatial parameter(s) for those TRP(s). For example, the index value may point to an entry (e.g., a row) of the table, and that entry may indicate the number of TRPs and the spatial parameter(s) for those TRPs.

Alternatively, the index value and a number of TB repetitions (e.g., an aggregation level, which may be indicated in DCI) may be used to determine the number of TRPs and the spatial parameter(s) for those TRP(s). For example, different entries (e.g., rows) in the table may indicate different numbers of TRPs (e.g., a single TRP, two TRPs, three TRPs, and/or the like) and corresponding spatial parameter(s) (e.g., QCL parameter(s), TCI state(s), and/or the like) for those TRP(s). In some aspects, a length of the entry or row (e.g., a number of values in the entry or row) may indicate the number of TRPs, and different entries (e.g., rows) may have different lengths. In some aspects, a first length (e.g., length <NUM>) may indicate a single TRP transmission mode, and a second length (e.g., greater than <NUM>) may indicate a multi-TRP transmission mode. Additionally, or alternatively, the length may indicate the number of TRPs in the multi-TRP transmission mode (e.g., two TRPs, three TRPs, and/or the like).

In some aspects, the number of TB repetitions may be used to identify multiple entries (e.g., rows) in the table (e.g., entries having the same length, corresponding to the number of TB repetitions), and the TCI index value may be used to identify a specific entry of those multiple entries. For example, different entries of the same length, corresponding to the same number of TRPs, may include different spatial parameter values for those TRPs. Thus, the number of TB repetitions may be used to determine multiple entries corresponding to a number of TRPs indicated by the number of TB repetitions, and the TCI index value may be used to identify specific spatial parameter values to be used for those TRPs.

In some aspects, a TB size may be determined based at least in part on the first TB repetition (e.g., using a set of TB size determination parameters associated with the first TB repetition), and that TB size may be used for all TB repetitions. In this way, TB repetitions of TBs having the same size may be enabled, regardless of whether different TB repetitions are associated with different sets of TB size determination parameters.

In some aspects, if the grant is a downlink grant, then the base station <NUM> may transmit, and the UE <NUM> may receive, the first TB repetition in the first min-slot and the one or more subsequent TB repetitions in the one or more subsequent mini-slots. In some aspects, different base stations <NUM> and/or TRPs <NUM> may schedule and/or transmit different TB repetitions. In some aspects, if the grant is an uplink grant, then the UE <NUM> may transmit, and the base station <NUM> may receive, the first TB repetition in the first min-slot and the one or more subsequent TB repetitions in the one or more subsequent mini-slots.

By using a single grant to indicate locations of multiple TB repetitions, network resources may be conserved that would otherwise be used to transmit multiple grants for the multiple TB repetitions. Furthermore, base station resources and UE resources (e.g., processing resources, memory resources, battery power, and/or the like) may be conserved that would otherwise be consumed to transmit, receive, and/or process multiple grants. Furthermore, by reusing one or more indicated parameters for multiple TB repetitions, additional network resources, base station resources, and UE resources may be conserved.

As shown by reference number <NUM>, rather than transmitting multiple TB repetitions (shown as "Rep <NUM>" and "Rep <NUM>"), a single communication (shown as "Longer Transmission") may be transmitted that has a longer duration than the individual TB repetitions. The single communication may have a smaller code rate (e.g., using a different MCS) than the TB repetitions would use, thereby making the single communication more reliable than either of the individual TB repetitions. In this case, because a single communication (e.g., a single TB) is used, there is no ambiguity when determining TB size. In some aspects, the single communication is a single codeword associated with a single redundancy version.

As shown by reference number <NUM>, the single communication may be transmitted or received in a first set of symbols using a first spatial parameter, and may be transmitted or received in a second set of symbols using a second spatial parameter. In some aspects, the number of symbols included in the first set of symbols (shown as X symbols) may be different from the number of symbols included in the second set of symbols (shown as Y symbols). In some aspects, the same number of symbols may be included in the first set of symbols and the second set of symbols. As described elsewhere herein, a spatial parameter may include a QCL parameter, a TCI state, a precoding parameter, a beamforming parameter, a spatial domain filter, a spatial relation, and/or the like. In example <NUM>, the first spatial parameter is shown as QCL <NUM> and the second spatial parameter is shown as QCL <NUM>. As further shown in <FIG>, in some aspects, the first set of symbols and the second set of symbols may be contiguous. However, in some aspects, the first set of symbols and the second set of symbols may be non-contiguous.

As shown by reference number <NUM>, a base station <NUM> (e.g., which may include one or more TRPs <NUM>) may transmit, and a UE <NUM> may receive, an indication of the first set of symbols and the second set of symbols in which the single communication (e.g., a single TB) is scheduled. As indicated above, the first set of symbols may be associated with a first spatial parameter, and the second set of symbols may be associated with a second, different spatial parameter.

In some aspects, the first set of symbols and the second set of symbols may be indicated using a first DMRS location and a second DMRS location. For example, a first symbol of the first DMRS (e.g., a symbol in which the first DMRS occurs) may indicate the starting symbol of the first set of symbols (e.g., the same symbol or an immediate next symbol), and a second symbol of the second DMRS (e.g., a symbol in which the second DMRS occurs) may indicate the starting symbol of the second set of symbols (e.g., the same symbol or an immediate next symbol). In this case, the indication may be implied using the first DMRS and the second DMRS. In some aspects, the DMRS locations may be indicated by the base station <NUM> to the UE <NUM>, such as in an RRC message, in DCI, and/or the like. In some aspects, the second DMRS may be additional DMRS used in addition to the first DMRS for more accurate channel estimation.

In some aspects, the first set of symbols and the second set of symbols may be indicated in DCI. For example, the first set of symbols and/or the second set of symbols may be implicitly indicated in DCI (e.g., according to DMRS locations, as described above). Additionally, or alternatively, the first set of symbols and/or the second set of symbols may be explicitly indicated in DCI, such as in a DCI field reserved for explicit indication of the first set of symbols and/or the second set of symbols. Additionally, or alternatively, the first spatial parameter and/or the second spatial parameter may be indicated in DCI.

As shown by reference number <NUM>, if the single communication is a downlink communication, then the base station <NUM> may transmit the single communication in multiple sets of symbols (e.g., the first set of symbols, the second set of symbols, and/or the like) using multiple spatial parameters (e.g., the first spatial parameter, the second spatial parameter, and/or the like). In this case, the UE <NUM> may receive the single communication in the multiple sets of symbols using the multiple spatial parameters. Alternatively, if the single communication is an uplink communication, then the UE <NUM> may transmit the single communication in multiple sets of symbols (e.g., the first set of symbols, the second set of symbols, and/or the like) using multiple spatial parameters (e.g., the first spatial parameter, the second spatial parameter, and/or the like). In this case, the base station <NUM> may receive the single communication in the multiple sets of symbols using the multiple spatial parameters.

Although operations are described herein as being performed by a base station <NUM>, in some aspects, one or more of these operations may be performed by multiple base stations <NUM>, multiple TRPs <NUM> that are included in the same base station <NUM>, multiple TRPs <NUM> that are included in different base stations <NUM>, and/or the like. For example, a first TRP <NUM> may transmit and/or receive in the first set of symbols, and a second TRP <NUM> may transmit and/or receive in the second set of symbols.

By using a single communication (e.g., a single TB) with a longer duration and smaller code rate than individual TB repetitions that could otherwise be used, reliability may be improved without creating ambiguity and additional complexity and processing in connection with determining a TB size for multiple TB repetitions.
