Abstract: Certain aspects of the present disclosure provide techniques for enhanced physical uplink control channel (PUCCH) transmission. In some cases, a UE obtains payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs), determines a group of the RBs available to the UE, and transmits the payload bits using the determined group of RBs, wherein the transmitting involves modulating different RBs of the group by at least one of different payload bits or sequences.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for distance-based channel occupancy time (COT) sharing. In one aspect, a first device, such as a user equipment (UE), may determine an approximate distance between itself and a second device. The first device may receive a COT sharing configuration including a set of COT sharing parameters for sharing a COT of the communications link with the second device based on the distance between the two devices. The first device may determine conditions for sharing the COT based on the COT sharing configuration and the approximate distance between the two devices. Additionally, or alternatively, the first device may determine conditions for sharing the COT based on the COT sharing configuration and a power metric of communications between the two devices.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive, from two or more transmitters, two or more sidelink control informations (SCIs) that schedule channel occupancy time (COT) resources for the two or more transmitters. The receiver may transmit, to a transmitter of the two or more transmitters, an acknowledgement or negative acknowledgement (A/N) feedback via a mini-slot carrying a physical sidelink feedback channel (PSFCH) or sidelink feedback information (SLFI) with SCI. The A/N feedback may be transmitted before a listen-before-talk (LBT) and physical sidelink shared channel (PSSCH) transmission. The receiver may receive, from the transmitter using a COT resource, the PSSCH transmission based at least in part on the A/N feedback. The LBT and the PSSCH transmission may be adjustable at the transmitter based at least in part on the A/N feedback. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in communication with a base station may support updating a bandwidth part (BWP) width from a default configuration. The UE may identify a first BWP, where the first BWP is a default BWP for communication with the base station. The UE may receive an indication of a second BWP from the base station that is wider than the first BWP. The indication may, in some cases, be included in a remaining minimum system information (RMSI), a master information block (MIB), or the like. The UE may select, based on the received indication and an operating band of the base station, the second BWP for communications between the UE and the base station. The UE and the base station may communicate using the second BWP.

Abstract: This disclosure provides systems, methods and apparatus for a user equipment (UE), operating in a shared spectrum in a connected state or an idle state, to receive a channel occupancy time structure information (COT-SI) which includes one or more of a COT duration, a COT end symbol, and a COT pause indication, in addition to slot format indication for one or more slots. Some aspects described herein define a hierarchical approach to COT structure information (COT-SI) signaling. For example, a UE may be configured with a set of short COT tables using remaining minimum system information (RMSI) signaling and may receive concatenation of COT-SI signaling identifying index values in a control channel corresponding to one or more of the set of COT tables. Based on receiving COT-SI signaling, the UE may communicate in accordance with an occurrence of a COT.

Abstract: Aspects of the disclosure relate to a user equipment (UE) for establishing a sidelink communication channel and receive mapped channel state information-reference signals (CSI-RS) over a plurality of PSSCH resource blocks. The mapped CSI-RS may be interlaced with resource elements in at least a portion of the plurality of PSSCH resource blocks. The CSI-RS received over the plurality of PSSCH blocks is then processed to determine a channel quality of the sidelink channel from the portion of the plurality of PSSCH resource blocks including the mapped CSI-RS.
