Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive, from a transmitter, an indication of a modulation signature associated with a reconfigurable intelligent surface (RIS). The receiver may receive a signal that uses the modulation signature, wherein the modulation signature identifies a link associated with the RIS and the transmitter. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine, based at least in part on an indication of communication frequency between the first UE and a second UE, a value for a discontinuous reception (DRX) parameter. The UE may transmit, to the second UE, DRX configuration information, the DRX configuration information indicating the value for the DRX parameter. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions to at least one receiver UE across transmission time intervals (TTIs), performing a listen-before-talk (LBT) channel access procedure in the TTIs, and transmitting at least one LBT report to the network entity on a physical uplink control channel (PUCCH) resource that occurs before another PUCCH resource used for transmitting acknowledgment feedback for the PSSCH transmissions.

Abstract: Aspects relate to measuring interference associated with sidelink communication. A UE that supports full-duplex communication may transmit on a first frequency resource and conduct self-interference measurements on a second frequency resource (e.g., a guard band) adjacent to the first frequency resource. Provisions may be made to ensure that other nearby wireless communication devices do not transmit on the second set of frequency resources when the UE is conducting an interference measurement. In a first resource allocation mode, a base station that allocates full-duplex resources for a first UE may ensure that any UEs that are near the first UE are not scheduled to transmit on a guard band when the UE is conducting an interference measurement. In a second resource allocation mode, a UE may reserve resources that are predefined with a guard band or the UE may reserve resources and use a subset of the resources for interference measurements.

Abstract: An aspect of this disclosure relates to a relay node, and a method of wireless communications by the relay node, including attempting to decode first code block groups of a transport block received in a resource allocation and according to a first encoding configuration. The aspects include identifying a symbol in the resource allocation that includes both of a first part of a successfully decoded one, and a first part of an unsuccessfully decoded one, of the plurality of first code block groups, and determining a modified transmit configuration for the symbol. Further, the aspects include encoding a second part of the successfully decoded one according to the first encoding configuration to define a second code block group that is outside of the symbol. Additionally, the aspects include transmitting the transport block including the one or more second code block groups and the symbol according to the modified transmit configuration.

Abstract: Aspects of the present disclosure provide systems and methods for assigning one or more user equipments (UEs) at one or more corresponding starting positions of multiple slots to perform channel access procedures, such as listen before talk (LBT) procedures in New Radio unlicensed band (NR-U) sidelink communications. The network entity may indicate, to a UE, a starting position in a multi-opportunity grant (e.g., a DCI scheduling multiple slots). The network entity may multiplex different transmitter UEs with different starting positions. If the channel accessing procedure is successful, the transmitter UE with the earliest starting position than the rest may block the rest of the transmitter UEs. In some cases, starting position hopping may be used so that the multiple UEs may have different priority at different slots. In some cases, the DCI may include LBT parameters that are inherited from NR-U uplink transmission configurations.

Abstract: A user equipment maps a high priority hybrid automatic repeat request-acknowledgment/negative acknowledgment (HARQ-ACK/NACK) information to one or more resource elements (REs), and maps one or more of a low priority HARQ-ACK/NACK information, channel state information (CSI), or uplink-shared channel (UL-SCH) data to REs while rate matching around the mapped high priority HARQ-ACK/NACK REs. A network entity receives an uplink transmission, including high and low priority HARQ-ACK/NACK information, CSI, and UL-SCH data mapped to high and low priority HARQ-ACK/NACK REs, CSI REs. and UL-SCH REs, respectively. The low priority HARQ-ACK/NACK REs, the CSI REs, and the UL-SCH REs are rate matched around the high priority HARQ-ACK/N ACK REs. The network entity demaps and decodes the REs of the high and low priority HARQ-ACK/NACK, the CSI, and UL-SCH to obtain the high and low priority HARQ-ACK/NACK information, CSI, and UL-SCH data.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: Aspects of the present disclosure allow a base station to simultaneously send SSBs to a UE and to associate different ROs or designated subsets of preambles with the simultaneously transmitted SSBs. The base station may configure a time or frequency offset for different ROs, or a number of preamble cyclic shifts associated with the SSBs. The base station then simultaneously sends a plurality of SSBs to the UE, where each of the SSBs is associated with a different beam, and where each of the SSBs is associated with a different RO or a designated subset of preambles. After the UE simultaneously obtains the SSBs from the base station, the UE may determine the offset for one of the different ROs, or the number of preamble cyclic shifts associated with one of the SSBs. The UE may then send a preamble to the base station in response to the determination.
