One apparatus includes a memory coupled to a processor, where the processor is configured to cause the second apparatus to receive a SL grant for a SL transmission using SL resources, the SL grant indicating a first HARQ process identified by a first HARQ process identifier, and to select a second SL HARQ process identified by a second SL HARQ process identifier for the SL transmission using the SL resources. The processor is configured to cause the second apparatus to transmit SCI containing the second SL HARQ process identifier and to perform the SL transmission using the SL resources.

A method and apparatus are provided, in which a service link path delay relative to a first leg of a communication path of a communication between the user equipment and a network entity via a relay entity is estimated (), where the first leg corresponds to a portion of the communication path between the user equipment and the relay entity. A feeder link path delay relative to a second leg of the communication path is determined (), where the second leg corresponds to a portion of the communication path between the relay entity and the network entity, based upon at least a received signaling indication. A timing advance value is calculated (), based upon the service link path delay and the feeder link path delay. An uplink transmission timing of the user equipment is adjusted (), based upon the calculated timing advance value.

Apparatuses, methods, and systems are disclosed for adjusting a contention window size. One apparatus includes a processor and a transceiver comprising a plurality of transmit panels.

The processor determines whether the directional transmission was successfully received by a recipient and updates a first contention window size specific to the first transmit panel. The processor performs a subsequent Listen-Before-Talk procedure using the updated first contention window size prior to a subsequent directional transmission using the first transmit panel.
