1. A resource allocation method operable by a base station, the base station comprising a Central Unit (CU) and a Distributed Unit (DU) connected to the CU, wherein the method comprises:
determining, by the DU, a Sidelink (SL) resource allocation mode; and
allocating, by the DU, SL resource for a UE according to the determined resource allocation mode and User Equipment (UE) context information,
wherein the SL resource allocation mode determined by the DU is a resource allocation mode scheduled by a network;
the step of allocating, by the DU, the SL resource for the UE according to the determined resource allocation mode and the UE context information, comprises:
acquiring, by the DU, Semi-Persistent Scheduling (SPS) assistance information that is related to UE V2X context information and transmitted by the CU;
generating, by the DU, SPS configuration information according to the stored UE V2X context information and the SPS assistance information, and transmitting, by the DU, the SPS configuration information to the CU; and
notifying, by the DU, the UE of SPS resource configuration information;
wherein the UE V2X context information comprises at least one of:
V2X authorization information; a PC5 aggregate maximum bit rate (PC5 AMBR); a mapping relationship between a transmission configuration table of the SL interface and destination L2 identifications; a Quality of Service (QOS) parameter of a service flow; a mapping relationship between Scheduling Request (SR) resources of a Uu interface.
