Abstract: Embodiments provide an information processing method, a base station, and user equipment. The method includes determining multiple subband groups, where the multiple subband groups are obtained by dividing multiple physical resource blocks corresponding to resource elements (REs) originally occupied by a CSI-RS, and each subband group in the multiple subband groups includes at least one subband. The method also includes determining a reference signal corresponding to each subband group in the multiple subband groups, where the reference signal corresponding to each subband group is generated by performing a precoding operation on the CSI-RS originally carried in first bearer REs in each subband in each subband group. Additionally, the method includes transmitting, by using the first bearer REs in each subband group in the multiple subband groups, the reference signal corresponding to each subband group.

Abstract: Embodiments of this application provide a time unit determining method and a communication apparatus. A network device indicates a time unit that is in a predefined time unit set and that belongs to a new radio network vehicle to everything (NR-V2X) resource pool to a terminal device, and indicates a time unit that is in the NR-V2X resource pool and that belongs to a long term evolution network vehicle to everything (LTE-V2X) resource pool to the terminal device, so that the terminal device can determine a time unit that is in the predefined time unit set and that belongs to both the NR-V2X resource pool and the LTE-V2X resource pool. According to the method, in a scenario in which LTE-V2X and NR-V2X coexist, conflicts between an NR-V2X resource and an LTE-V2X resource are reduced, thereby improving data transmission reliability.
