Abstract:
Embodiments of this application provide a signal transmission method and apparatus, and the method includes: filtering a first time domain orthogonal frequency division multiplexing (OFDM) signal at each of M spatial transmission layers, where M is an integer greater than or equal to 1; performing spatial precoding on the filtered first time domain OFDM signal at each of the M spatial transmission layers, and mapping the filtered first time domain OFDM signal at each of the M spatial transmission layers to each of N t  transmit antenna ports, where N t  is an integer greater than or equal to M; and superposing and transmitting the first time domain OFDM signals that are at the M spatial transmission layers and that are mapped to all the N t  transmit antenna ports.

Claim (Index 11):
The apparatus according to  claim 7 , wherein the programming instructions instruct the at least one processor to:\n map, by using a time domain precoding vector W i  on first filtering bandwidth, the filtered first time domain OFDM signal at an i th  spatial transmission layer in the M spatial transmission layers to each of the N t  transmit antenna ports, wherein i=1, 2, . . . , M, and i represents an index of the M spatial transmission layers.
