Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of HARQ for NR sidelink communication in unlicensed spectrum. The method comprises receiving, from a second device, an indication of at least two candidate sets of code domain resources for the first device to transmit a feedback message for a sidelink transmission between the first device and a third device; and transmitting, to the third device, the feedback message on a target set of code domain resources determined from the at least two candidate sets of code domain resources based on a listen before talk procedure. In this way, additional code domain resources may provide more available time occasions as backup resources for HARQ feedback of sidelink transmission in unlicensed band, which may increase reliability of HARQ feedback transmission for sidelink communication in unlicensed spectrum. Hence it can eventually increase spectral efficiency by avoiding unnecessary retransmission of PSCCH/PSSCH, and can also reduce transmission latency in the meantime.

Abstract: Embodiments of the present disclosure relate to transmission of sidelink feedback information on unlicensed spectrum. The first device transmits a configuration to a second device and a third device. The configuration indicates a primary resource and at least one backup resource, where the primary resource is to be used by the third device for transmitting feedback information of a sidelink transmission to the second device, the sidelink transmission being transmitted by the second device on an unlicensed resource, and the at least one backup resource is to be used by the third device for transmitting the feedback information of the sidelink transmission without performing a channel assessment.

Abstract: There is provided an apparatus, said apparatus comprising means for providing first control information using a first control channel and at least second control information using a second control channel, wherein the first control information comprises at least an indication of resource reservation for an associated data channel and the second control information comprises at least transmission format information for the associated data channel, wherein the associated data channel comprises periodic or aperiodic data traffic.
