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 4):
The method according to  claim 3 , wherein the method further comprises:\n filtering a third time domain OFDM signal corresponding to each of the N t  transmit antenna ports at a fifth sampling rate, wherein the fifth sampling rate is greater than the first sampling rate, the third sampling rate, or both; and the 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 comprises: 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, the second time domain OFDM signals at the N spatial transmission layers, and the filtered third time domain OFDM signal.
