Abstract

A wireless communication system includes one or more base stations, and a plurality of UEs for a sidelink communication using sidelink resources. The UEs includes a transmitting UE and a receiving UE using a subset of the sidelink resources of the wireless communication system. The receiving UE sends over the sidelink a sidelink feedback to the transmitting UE. The sidelink feedback indicates for a data transmission a successful or non-successful reception at the receiving UE. The transmitting UE reports the sidelink feedback to a base station. The base station provides to the transmitting UE, responsive to the sidelink feedback, sidelink resources for a possible retransmission of a data packet over the sidelink to the receiving UE. The reporting of the sidelink feedback to the base station by the transmitting UE is activated or deactivated responsive to one or more conditions.
