Abstract
An apparatus and a method of vehicle-to-everything (V2X) communication of same are provided. The apparatus is a local header. The method includes pre-allocating a plurality of transmission opportunities of a plurality of sidelink (SL) resources in a time domain multiplexed (TDM'ed) manner, and coordinating transmission timings between a plurality of group member user equipments (UEs) in a unicast session or a groupcast session.
Claims6
An apparatus in a vehicle-to-everything (V2X) communication system, the apparatus being a local header and comprising:
- a memory;
- a transceiver;
- and
- a processor coupled to the memory and the transceiver,
- wherein the processor is configured to:
- pre-allocate a plurality of transmission opportunities of a plurality of sidelink (SL) resources in a time domain multiplexed (TDM′ed) manner;
- and
- coordinate transmission timings between a plurality of group member user equipments (UEs) in a unicast session or a groupcast session,
- wherein the processor is configured to pre-allocate the transmission opportunities of the sidelink (SL) resources in a fair-proportional manner by assigning a start timing or a reference timing, and a UE transmission sequence or a UE member ID for each of the group member UEs, and each of the group member UEs based on a corresponding UE member ID computes the transmission timings in which each of the group member UEs is allowed to transmit a plurality of SL messages according to a following modulo equation:
- (SFN×10+slot number) mod (number of group member UEs)=UE member ID−1;
- or
- wherein the processor is configured to pre-allocate the transmission opportunities of the sidelink (SL) resources by assigning a start timing and a slot bitmap sequence for each of the group member UEs.
A method of vehicle-to-everything (V2X) communication of an apparatus, the apparatus being a local header, the method comprising:
- pre-allocating a plurality of transmission opportunities of a plurality of sidelink (SL) resources in a time domain multiplexed (TDM′ed) manner;
- and
- coordinating transmission timings between a plurality of group member user equipments (UEs) in a unicast session or a groupcast session,
- wherein the method further comprises pre-allocating the transmission opportunities of the sidelink (SL) resources in a fair-proportional manner by assigning a start timing or a reference timing, and a UE transmission sequence or a UE member ID for each of the group member UEs, and each of the group member UEs based on a corresponding UE member ID computes the transmission timings in which each of the group member UEs is allowed to transmit a plurality of SL messages according to a following modulo equation:
- (SFN×10+slot number) mod (number of group member UEs)=UE member ID−1;
- or
- wherein the method further comprises pre-allocating the transmission opportunities of the sidelink (SL) resources by assigning a start timing and a slot bitmap sequence for each of the group member UEs.
