Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may belong to a group of UEs and may identify a channel sensing schedule for the group of UEs. The channel sensing schedule may include sensing windows and resource reservation windows corresponding to each UE of the group of UEs. The channel sensing schedule may establish a pattern for the sensing windows and resource reservation windows such that the UEs may take turns performing sensing and resource selection. During a sensing window associated with the UE, the UE may sense a set of resources of a sidelink communication link to identify candidate resources. The UE may transmit, to the other UEs of the group, a message indicating results of the sensing, such as an indication of resource reservations, candidate resources, or the like. The other UEs may identify and select candidate resources based on the message.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity (e.g., UE, gNB, LMF, etc.) identifies a pool of UEs for a SL-assisted position estimation procedure of a set of target UEs. SL SRS-Ps are communicated (e.g., transmitted and measured) between the pool of UEs (e.g., for relative SL ranging). UL SRS-Ps are communicated by at least some of the UEs in the pool of UEs. The position estimation entity obtains measurement data for both the SL SRS-P and UL-SRS-P communications. The position estimation entity determines a position estimate for each UE in the set of UEs based on the measurement information.

Abstract: Aspects are provided which allow a base station to indicate use of a mini-slot based resource allocation in sidelink communications between a Tx UE and a Rx UE. Initially, the base station configures control information indicating a sidelink data resource for a mini-slot, and transmits the control information to a Tx UE. After the Tx UE receives the control information, the Tx UE transmits sidelink data in the sidelink data resource to a Rx UE. Similarly, the Rx UE receives the control information from either the Tx UE or the base station, and the Rx UE receives the sidelink data in the sidelink data resource from the Tx UE. Accordingly, the base station may schedule the Tx UE and Rx UE to communicate sidelink data in mini-slots rather than slots, thereby reducing scheduling latency, increasing the number of available resources, and achieving more flexibility in sidelink communications.
