Abstract: Aspects relate to direct current (DC) tone indication on the sidelink A wireless communication device (e.g., a UE) may transmit an indication of its sidelink DC tone to one or more other UEs via respective sidelinks. In an example, a transmitting UE may transmit an indication of its sidelink DC tone within second stage sidelink control information included within a data region of a slot. A receiving UE may further transmit an indication of its sidelink DC tone to a transmitting UE over a sidelink between the transmitting UE and receiving UE or a base station in wireless communication with the transmitting and receiving UEs may provide the indication of the sidelink DC tone of the receiving UE to the transmitting UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may map channel state information (CSI) to first resource elements that are distributed in frequency, wherein the first resource elements are in a set of resources allocated on an uplink shared channel; map hybrid automatic repeat request (HARQ) feedback to second resource elements that are distributed in frequency, wherein the second resource elements are in the set of resources; wherein the second resource elements are reserved for the HARQ feedback and are different from the first resource elements; and transmit the CSI and the HARQ feedback on the uplink shared channel in accordance with the mappings. Numerous other aspects are provided.

Abstract: Aspects relate to supporting power control for physical uplink control channel (PUCCH) transmissions on an uplink secondary component carrier (SCC) of a wireless communication system. In some aspects, a user equipment (UE) receives a power control configuration from a base station for use by the UE for a PUCCH transmission on a selected uplink SCC. The UE then transmits, based at least in part on the power control configuration, the PUCCH to the base station on the selected uplink SCC. Closed-loop and open-loop power control examples are provided. In some aspects, common or shared power control configurations are provided by the base station for use with each component carrier of a PUCCH group. In other aspects, carrier-specific power control configurations are provided by the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may determine whether to multiplex or prioritize a first communication and a second communication that are scheduled for simultaneous transmissions via a first channel and a second channel, respectively. The mobile station may transmit one or more of the first communication or the second communication based at least in part on the determination of whether to multiplex or prioritize the first communication and the second communication. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that multiple physical uplink channels scheduled for the UE overlap. The multiple physical uplink channels may include a first physical uplink channel and a second physical uplink channel that are associated with different priority levels. The UE may transmit at least one of the first physical uplink channel or the second physical uplink channel according to a prioritization or a multiplexing of the first physical uplink channel and the second physical uplink channel. The prioritization or the multiplexing is based at least in part on whether the UE is enabled to perform simultaneous physical uplink control channel and physical uplink shared channel transmissions. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a plurality of physical uplink control channel (PUCCH) repetitions of different lengths using vectors of orthogonal cover code (OCC) matrices that differ in size across two or more of the plurality of PUCCH repetitions. The UE may transmit the plurality of PUCCH repetitions. Numerous other aspects are provided.

Abstract: Aspects enable and provide techniques for sidelink communication resource configuration and management. A first user equipment (UE) negotiates with a second UE to select a first communication resource set (ComReSet) from a plurality of ComReSets for sidelink communication. Each of the plurality of ComReSets has a corresponding periodicity of one or more hyper-frames. The first UE communicates with the second UE using the first ComReSet using a frame timing synchronized with the corresponding periodicity of the first ComReSet.

Abstract: Aspects presented herein may enable the base station to apply coverage enhancement for one or more SSB beam(s) or a subset of SSB beams for broadcasting system information in a more efficient manner, where the base station and the UE may adapt the system information differently for different SSB beams. In one aspect, a UE may receive, from a base station, RMSI indicating beam-specific system information in association with one or more SSB beams for receiving an SSB. Then, the UE may receive the SSB from the base station based on the received RMSI indicating the beam-specific system information.
