Abstract: A method of wireless communication performed by a first user equipment (UE) includes receiving second data from a remote UE and receiving an uplink transmission grant from a base station. The method also includes generating a payload comprising the second data from the second UE or first data from the first UE. The method additionally transmits the payload to the base station via an uplink resource identified in the uplink transmission grant.

Abstract: Aspects of the present disclosure provide techniques that help reducing transmission overhead related to sidelink control information (SCI). For example, when a transmitter UE has established a sidelink communication with a receiver UE, the transmitter UE may schedule with at least one semi-persistent scheduling (SPS) process at a first time interval. The transmitter UE may sense whether a resource is available for transmissions to the receiver UE based on decoding an SCI, such as an SCI 0-1 message. The SCI is transmitted at a second time interval that is greater than the first time interval. For example, the second time interval may be a multiple of the first time interval of the at least one SPS process. The second time interval may be flexible and may be increased to reduce the number of SCI messages transmitted in certain time periods in order to reduce communication overhead.

Abstract: A method, apparatus, or computer-readable medium with instructions for beam management for radio frequency (RF) sensing at a wireless device. The wireless device performs a first beamsweep of an RF signal and measures a reflection of the RF signal based on the first beamsweep. The wireless device performs a second beamsweep of the RF signal, wherein the first beamsweep is based on a different parameter than the second beamsweep and measures the reflection of the RF signal based on the second beamsweep. The wireless device selects a beam for RF sensing based on the first beamsweep and the second beamsweep.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE via a sidelink sub-channel of a primary carrier, an indication that identifies one or more resources on the primary carrier for transmitting one or more hybrid automatic repeat request (HARQ) responses for one or more sidelink communications between the first UE and the second UE on a secondary carrier; and receive, from the second UE, on the one or more resources on the primary carrier, the one or more HARQ responses for the one or more sidelink communications on the secondary carrier. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to channel occupancy management for new radio side-link supporting star topology of user equipment devices are provided. In some aspects, a user equipment (UE) determines a communication resources pool including a channel occupancy ratio (CR) gap of each UE of a plurality of UEs in communication with the first UE, a CR gap of each UE representing a difference between a CR limit of that UE and a CR of that UE, The UE also can communicate, to a second UE of the plurality of UEs, a first CR command configured to allow the second UE to access a first portion of the communication resources pool. In some aspects, an amount of the first portion can be different from an amount of the CR gap of the second UE in the communication resources pool.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive, from a base station, information indicating resource locations in which one or more synchronization signal blocks (SSBs), of a set of SSBs, are to be transmitted. The mobile station may selectively monitor a plurality of sets of resource element groups (REGs) of physical downlink control channel (PDCCH) repetitions based at least in part on whether at least one SSB, of the one or more SSBs, is to collide with one or more of the plurality of sets of REGs.

Abstract: Aspects relate to configuring and managing hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback codebooks for use in wireless communication systems. The HARQ-ACK codebooks include priority-based HARQ-ACK codebooks of differing priorities, such as Type 1 and Type 2 codebooks, and one-shot (Type 3) HARQ-ACK codebooks. In one example, a wireless communication device may be configured to obtain a set of HARQ-ACK codebooks that include priority-based HARQ-ACK codebooks of differing priorities and a separate one-shot HARQ-ACK codebook. The wireless communication device may further be configured to process first and second physical uplink channels based on the priority of the first physical uplink channel and the priority of the second physical uplink channel, where one of the two physical uplink channels includes the one-shot HARQ-ACK codebook, and with the processing performed in combination with the use of the priority-based HARQ-ACK codebooks.
