Abstract: Aspects of the disclosure provide techniques for waveform indication for physical uplink control channel (PUCCH) transmissions. A network entity may provide an indication of a waveform type, such as CP-OFDM, DFT-s-OFDM, or other suitable waveform type, for a PUCCH format to a user equipment (UE). The UE may then communicate a PUCCH with the network entity using the waveform type for the PUCCH format.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a sidelink slot format, wherein the sidelink slot format indicates a configuration of sidelink feedback resources. The UE may measure a signal, associated with a channel access procedure, after a first symbol of a first sidelink slot and prior to a mini-slot of the first sidelink slot, and wherein the sidelink slot format indicates that the first sidelink slot is associated with the sidelink feedback resources. The UE may transmit, using a transmission starting location of the mini-slot or of a symbol of a second sidelink slot, a sidelink communication based at least in part on the measurement of the signal, wherein a format of the sidelink feedback resources is based at least in part on the transmission starting location. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a nominal resource block value associated with one or more allocated subchannels for a sidelink communication. The UE may identify a number of physical sidelink shared channel (PSSCH) resource elements to be used for a transport block size calculation based at least in part on the nominal resource block value. The UE may transmit the sidelink communication, and reserve one or more resources for one or more respective retransmissions of the sidelink communication, based at least in part on the number of PSSCH resource elements. Numerous other aspects are described.

Abstract: Systems, devices, and methods for mapping wideband sidelink (SL) resources to SL feedback resources are provided. For example, a method of wireless communication performed by a user equipment (UE) comprises: receiving, based on at least a first interlace of resource blocks (RBs) and based on two or more RB-sets of a shared frequency band, a SL communication; and transmitting, using at least a second interlace of RBs and using resources from at least one RB-set of the two or more RB-sets of the shared frequency band, a SL feedback communication for the SL communication. In some aspects, the transmitting the SL feedback communication is based on a mapping of the two or more RB-sets to the at least one RB-set.

Abstract: Apparatus, methods, and computer-readable media for multiplexing of overlapped uplink channel transmission repetitions are disclosed herein. A user equipment (UE) may determine that at least a portion of a first set of uplink channel transmission repetitions overlaps with at least a portion of a second set of uplink channel transmission repetitions. The UE may modify the first set of uplink channel transmission repetitions based on the second set of uplink channel transmission repetitions. A base station (BS) may transmit a first downlink transmission associated with the first set of uplink channel transmission repetitions that overlaps with at least a portion of a second set of uplink channel transmission repetitions associated with a second downlink transmission. The BS may receive a modified version of the first set of uplink channel transmission repetitions based on the second set of uplink channel transmission repetitions. Thus, the reliability of uplink repetitions can be increased.

Abstract: Wireless communication systems and methods related to multiplexing of uplink control information (UCI) and configured grant-UCI (CG-UCI) of different priorities are provided. A user equipment (UE) determines that a physical uplink control channel (PUCCH) resource at least partially overlaps with a configured grant physical uplink shared channel (CG-PUSCH) resource, where the PUCCH resource and the CG-PUSCH resource are associated with different priorities. The UE, based on a threshold number of bits, a number of bits of a low-priority uplink control information (UCI) for multiplexing with at least one of a high-priority CG-PUSCH transmission, a low-priority CG-PUSCH transmission, or a high-priority UCI. The UE multiplexes the number of bits of the low-priority UCI with the at least one of the high-priority CG-PUSCH transmission, the low-priority CG-PUSCH transmission, or the high-priority UCI to generate a multiplexed uplink transmission, and transmits the multiplexed uplink transmission in the PUCCH resource or the CG-PUSCH resource.

Abstract: A UE may receive a first indication of a mapping of a plurality of layers to a c-CW and a p-CW from a network entity, indicating that the c-CW corresponds to at least one first layer of the plurality of layers and the p-CW corresponds to at least one second layer of the plurality of layers. The plurality of layers, the c-CW, and the p-CW may be associated with rate-splitting for MIMO communication. The UE may identify a first set of modulated symbols and a second set of modulated symbols that are mapped to the at least one first layer and the at least one second layer, respectively, based on the first indication. The UE may perform a decoding process for at least one of the c-CW or the p-CW based on at least one of the first set of modulated symbols or the second set of modulated symbols.

Abstract: Certain aspects of the present disclosure provide a user equipment (UE) that may receive an indication of a proximity discovery resource in a physical sidelink feedback channel (PSFCH) symbol from a network entity. The UE may transmit a proximity discovery request including the indication of the proximity discovery resource. The UE may receive a PSFCH sequence associated with the proximity discovery resource from other UEs that may respond to the proximity discovery request. The UE may transmit a bit map sequence indicative of the other UEs to the network entity. The network entity may determine a proximity between the UE and the other UEs based on the bit map sequence. The network entity may schedule the UE and the other UEs based on the proximity.
