Patent ID: 11025374

Abstract:
A user equipment (UE) includes a controller configured to identify a pool of HARQ process numbers that is configured by a base station for transmission on a sidelink channel, search one or more a scheduling assignments of one or more other UEs to determine whether any of the HARQ process numbers are being used by other UEs, exclude HARQ process numbers that are being used from the configured pool of HARQ process numbers, select a HARQ process number from the remaining HARQ process numbers in the configured pool, generate a SCI to include the selected HARQ process number. The UE further includes a transmitter configured to perform a transmission or re-transmission of a packet over a sidelink to another UE(s), using the selected HARQ process number. Methods and apparatus for multi-beam based transmission for the sidelink and V2X communication are also disclosed.
