Abstract:
The present document provides a precoding method and system for open loop spatial multiplexing and a precoding indication method. The method includes: in transmission resources, a base station precodes N-layer data to be sent by using w a = [ u a a · u a ] , wherein ua is a vector or matrix related to a transmission resource location i; α is a real number or a complex number related to the transmission resource location i; and N is an integer less than or equal to the number of base station transmission antennas.
