Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may set, for frequency hopping of multiple physical uplink shared channel (PUSCH) repetitions of multiple transport blocks (TBs), a first frequency for a first frequency hop and a second frequency for a second frequency hop. The UE may transmit the PUSCH repetitions with frequency hopping such that the PUSCH repetitions alternate between the first frequency hop and the second frequency hop. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described to support accounting for contention-exempt synchronization signal blocks (SSBs) when validating one or more channel state information reference signals (CSI-RS). A base station may transmit, to a user equipment (UE), an indication of the one or more contention-exempt SSBs, and the UE may determine to monitor for a configured CSI-RS if resources assigned to the CSI-RS fall within a time frame associated with the one or more contention-exempt SSBs. Similarly, the base station may transmit configured CSI-RS if resources assigned to the CSI-RS fall within a time frame associated with the one or more contention-exempt SSBs. The time frame associated with the one or more contention-exempt SSBs may include a slot that includes the SSB(s), a symbol that includes the SSB(s), symbols between the SSB(s), slots between the SSB(s), or any combination thereof.

Abstract: Certain aspects of the present disclosure provide a technique for parallel distribution matching (DM) encoding. A user equipment (UE) implements the technique to perform a first round of parallel DM encoding using k information bits as input by: 1) segmenting the k information bits into N blocks of information bits, and 2) encoding the N blocks of information bits in parallel with N DM blocks. Each of the N blocks outputs one or more encoded information bits in each of the NDM blocks, and a total number of information bits output by the N DM blocks is less than k. The UE then performs a second round of parallel DM encoding using k′ information bits that were not encoded in the first round of DM encoding. The second round of parallel DM encoding includes a same encoding process as implemented in the first round of parallel DC encoding.

Abstract: A configuration for transmission control for multi-relay based communication. The apparatus determines a priority of data transmission at each relay of a plurality of relays between the base station and at least one UE. The apparatus transmits a PDSCH comprising control information for the at least one UE and a priority indication instructing each relay of the plurality of relays which data is contained in the PDSCH. The PDSCH may include an indication indicating whether data corresponding to the at least one UE is contained in the PDSCH. The PDSCH may include a field that identifies data and a corresponding UE of the at least one UE that is contained in the PDSCH. The apparatus may transmit, to each relay of the plurality of relays, the priority of data transmission, wherein the priority of data transmission includes a priority for uplink and downlink transmissions.

Abstract: Example aspects include a method, apparatus, and computer-readable medium for wireless communication at user equipment of a mobile network, comprising receiving, from a base station via a first beam, a pre-grant message requesting the UE to perform a listen-before-talk (LBT) procedure on a second beam. The aspects further include performing, according to the pre-grant message, the LBT procedure on the second beam. Additionally, the aspects include indicating, to the base station, whether the LBT procedure was successful.

Abstract: Methods, systems, and devices for power backoff techniques for modulation schemes are described. A user equipment (UE) may receive an indication of a constellation distribution parameter and a modulation scheme to be used by the UE for an uplink message on an uplink channel. The UE may determine an uplink transmission power based at least in part on the indicated constellation distribution parameter and the indicated modulation scheme. The UE may transmit the uplink message using the indicated modulation scheme according to the determined uplink transmission power. In some examples, the UE may transmit a report indicating a power headroom parameter and an output power parameter based at least in part on the constellation distribution parameter.

Abstract: Wireless communications systems and methods related to routing communications in a multiple-relay environment are provided. A base station (BS) transmits, to one or more wireless communication devices, a reference signal configuration indicating one or more reference signal resources. The base station receives, from a first wireless communication device of the one or more wireless communication devices, a channel state report based on one or more reference signals in the one or more reference signal resources. The channel state report includes channel measurement information for one or more links, each link connecting a wireless communication device of the one or more wireless communication devices to a user equipment (UE). The BS transmits, to the UE via a second wireless communication device of the one or more wireless communication devices based on the channel state report, a data signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an uplink grant scheduling an uplink transmission that is not aligned with a fixed frame period (FFP) boundary configured for the UE. The UE may receive downlink control information (DCI) including an indication that the UE is to initiate a channel occupancy time (COT) acquisition in association with transmitting the uplink transmission. The UE may modify the indication based at least in part on the uplink transmission not being aligned with the FFP boundary and the indication indicating that the UE is to initiate the COT acquisition. The UE may transmit the uplink transmission based at least in part on the uplink grant and after the modification of the indication. Numerous other aspects are described.
