Abstract: A communication method and apparatus, capable of implementing physical uplink shared channel (PUSCH) transmission of Z antenna ports. When Z is small, the method can be suitable for more popular terminals having fewer uplink transmitting antennas, thereby saving terminal costs. The method comprises: a terminal transmits a first PUSCH via Z antenna ports, wherein the Z antenna ports perform precoding on the basis of a third precoding matrix, the third precoding matrix comprises a first precoding matrix and/or a second precoding matrix, or the third precoding matrix comprises a sub-matrix of the second precoding matrix, and Z is a positive integer greater than 1. The first precoding matrix is a precoding matrix for PUSCH transmission of K antenna ports, wherein K is a positive integer; the second precoding matrix is a precoding matrix for PUSCH transmission of Y antenna ports, wherein Y=2X, and X is a positive integer. Exemplarily, K=1, Y=2, and Z=3; or Y=4 and Z=3.
