Abstract: A method for wireless communication performed by a first sidelink user equipment (UE) includes receiving, from a network entity, a sidelink grant allocating sidelink resources for communicating with a second sidelink UE. The method also includes transmitting, to the network entity via uplink resources, a feedback message based on whether one or both of a first sidelink packet condition or a second sidelink packet condition are satisfied. The method further includes transmitting, to the second sidelink UE via the sidelink resources, a sidelink packet based on both the first sidelink packet condition and the second sidelink packet being satisfied.

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.

Abstract: Aspects relate to a base station configured to transmit a message to a sidelink (SL)-repeater, configuring the SL-repeater to transmit sidelink synchronization signal blocks (S-SSBs) including S-SSB index numbers, receive a SL-node identification and a preferred S-SSB index number, and transmit the SL-node identification and the preferred S-SSB index number to the SL-repeater. The base station may be configured to transmit a first message configuring a SL-repeater to broadcast a sidelink discovery message, receive a sidelink discovery report from the SL-repeater identifying discovered SL-node(s), and transmit a second message activating the SL-repeater for sidelink communication with the SL-node(s). Another aspect relates to a SL-repeater configured to: transmit a sidelink discovery message, receive first response(s) from respectively responding SL-node(s), and transmit a report to a base station identifying a change in membership between a first list of the respectively responding SL-node(s) and a second list of previously responding SL-nodes.

Abstract: Aspects of the present disclosure provide techniques for sidelink repeating operations, such as by using an assisting node (e.g., a smart repeater, relay, or reflector) to enhance sidelink communication reliability. For example, one or more assisting nodes may be configured by a network entity and repeat sidelink communications for two or more user equipments (UEs). In aspects, an assisting node may receive, from the network entity, an indication of resources available for sidelink communications between a first UE and a second UE. The assisting node may also receive signaling that configures the assisting node to repeat sidelink communications between the first and the second UEs over the indicated resources. The assisting node then repeats sidelink communications between the first and the second UEs according to the received signaling.
