  • Patent number: 11979238
    Abstract: A user device, UE, for a wireless communication system is described. The wireless communication system includes a plurality of user devices, UEs. The UE communicates with one or more transmitting UEs using a sidelink, supports a certain number of HARQ processes, and buffers one or more transmissions for each HARQ process. During a unicast communication with a transmitting UE using the sidelink, the UE receives from the transmitting UE a transmission during a transmission time interval, the transmission associated to control data, e.g. SCI, including a HARQ process ID, buffers the received transmission for the HARQ process, and combines the buffered transmissions prior to decoding. In case a successfully identified transmission is not buffered, the UE indicates to the transmitting UE that the transmission is not buffered at the UE.

  • Patent number: 11950326
    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.
