Abstract: Techniques for performing sidelink discovery with user equipment (UE) to UE relay are provided. An initiating UE initiates a sidelink discovery solicitation message toward relay UEs and responding UEs. A relay UE can facilitate the discovery between two or more UEs by monitoring for sidelink discovery solicitation messages and sidelink discovery solicitation responses. A responding UE in receipt of a sidelink solicitation message responds toward a relay UE and/or initiating UE via communication method that may depend on various factors. The communication method may include non-unicast communication, such as broadcast or multicast, to reduce signaling overhead in comparison to unicast communication methods.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of Channel Occupancy Time (COT) for Sidelink (SL) communication in Unlicensed band (U-band). The method includes receiving, at a first device and from a second device, configuration information associated with a COT at least for a SL transmission of the first device on an unlicensed resource pool allocated for the first device, the configuration information at least indicating whether a listen before talk procedure is required to be performed at the first device within the COT before the SL transmission; and performing the SL transmission within the COT based on the configuration information. In this way, the COT sharing mechanism can be used for SL communications in U-band and therefore a sensing procedure for resource selection may not be impacted by the LBT procedure.

Abstract: An ARQ system for sidelink communication between transmitter and receiver, with the help of cooperative UE, or relay UE is disclosed. The relay intercepts the initial transmission from transmitter to receiver. If the relay does not intercept any ARQ feedback from the receiver (DTX), it retransmits the initial transmission. Upon receiving at least the Sidelink Control Information, SCI, identifying the retransmission, the transmitter terminates the HARQ process, assuming that the relay is now in charge of the retransmission. Upon reception of the retransmission, the receiver feeds back an HARQ ACK to the relay and the transmitter. If the receiver correctly receives the initial transmission, it feeds back an HARQ ACK to the relay and the transmitter and both relay and transmitter stop the HARQ process. If the relay does not successfully receive the initial transmission, it feds back a NACK to the transmitter which performs retransmission to the relay.
