Abstract

Embodiments provide a spatial flow determining method, a base station, and user equipment. The method includes sending, by a base station, a feedback mode indication to user equipment, where the feedback mode indication is used to instruct the user equipment to feed back, based on a packet granularity, channel state report (CSR) information, and each packet granularity includes at least one spatial flow. The method also includes receiving, by the base station, CSR information of each packet granularity that is sent by the user equipment; and determining, by the base station according to the CSR information of each packet granularity, a spatial flow used to transmit data to the user equipment.
