Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first vehicle-to-every thing (V2X) device may receive, via a first radio access network (RAN), a scheduling assignment for a second V2X device. The first V2X device may decode the scheduling assignment to determine resource reservation information for the second V2X device on the first RAN. The first V2X device may modify at least one transmission associated with a second RAN based at least in part on the resource reservation information for the second V2X device on the first RAN. In some aspects, the first V2X device may transmit a coordination message for reception by one or more other V2X devices associated with a second RAN. The coordination message may include the resource reservation information for the second V2X device associated with the first RAN. Numerous other aspects are described.

Abstract: A first user equipment (UE) wakes up a second UE to request information using an application specific sidelink wake up signal (SL-WUS). The first UE determines a sidelink configuration of the second UE that is configured with a discontinuous reception (DRX) mode. The first UE transmits the SL-WUS on a configured resource monitored by the second UE during the DRX mode. A selection of a sequence of the SL-WUS or a selection of the configured resource indicates a type of information requested by the first UE. The second UE receives the SL-WUS, wakes up during a DRX on duration, and transmits the requested information. The first UE receives the type of information requested by the first UE.

Abstract: The apparatus may be configured to receive a plurality of indications for a plurality of TBs for the network encoding device to retransmit and to transmit, to a plurality of UEs, a FCNC request for a subset of the plurality of TBs for collecting feedback information regarding the subset of the plurality of TBs, the FCNC request being a NC packet including a second indication that the NC packet is associated with an FCNC feedback configuration, the FCNC feedback configuration being different from a feedback configuration for NC packets that are not FCNC requests. The apparatus may also be configured to receive, from at least one of the plurality of UEs, feedback associated with the FCNC request based on the FCNC feedback configuration and to encode, based on the received feedback, the plurality of TBs in at least one NC packet for transmission to the plurality of UEs.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a transmitter user equipment (UE) transmits, by a transmitter transmit-receive point (TRxP) of the transmitter UE on a transmit beam, a self-interference management reference signal (SIM-RS) during a first beam training occasion shared among a plurality of UEs for transmitting beam training reference signals (BT-RS) for sidelink communications among the plurality of UEs, and measures, by a receiver TRxP of the transmitter UE on a receive beam, self-interference at the receiver TRxP caused by transmission of the SIM-RS by the transmitter TRxP.

Abstract: Techniques for cross channel occupancy time (COT) hybrid automatic repeat request (HARQ) feedback transmission for sidelink communication in unlicensed spectrum may be performed. In an example, a receiving user equipment (UE) may receive, from a transmitting UE, a first transmission in a first channel occupancy time (COT). The receiving UE may also determine a first feedback occasion is after a last slot of the first COT. The receiving UE may also determine one or more feedback configurations. The receiving UE may also transmit, to the transmitting UE, a feedback message indicating decoding of the first transmission in the first feedback occasion or a second feedback occasion based on the one or more feedback configurations.

Abstract: Methods, systems, and devices for wireless communication are described to support selection of an unoccupied sidelink resource associated with a higher communication quality in a shared spectrum. User equipments (UEs) operating in shared spectrum may be configured with a set of candidate carriers for sidelink communications using the shared spectrum. A transmitting UE may select a number of resources for a sidelink transmission that are available in a same transmission time occasion and on multiple carriers of the set of carriers. The UE may perform a channel access procedure for each carrier of the multiple carriers prior to the transmission time occasion and may transmit a sidelink communication on at least one selected resource if the channel access procedure succeeds in at least one of the carriers of the multiple carriers.
