Abstract:
Embodiments of the present disclosure provide a precoding method, a base station and a user equipment. The precoding method comprises: a base station acquires predetermined parameter(s) of at least one user equipment; calculates the acquired predetermined parameter(s) to obtain a calculation performance index; selects a target precoding solution according to the calculation performance index; precodes data information of all the user equipment(s) according to the target precoding solution; if the target precoding solution is a nonlinear precoding solution, sends the data information and indication signaling indicating information of the nonlinear precoding solution to each user equipment; and the user equipment receives the data information and the indication signaling which are sent by the base station; selects a receiver according to a receiver type obtained according to the indication signaling; and detects the received data information using the selected receiver.
