摘要： This application discloses a sensing method and a communication apparatus, to improve sensing performance. The method includes: A first communication apparatus determines first information, where the first information indicates a pulse repetition interval PRI. The first communication apparatus sends the first information to a second communication apparatus. Correspondingly, the second communication apparatus receives the first information from the first communication apparatus. The first information is used by the second communication apparatus to send a reference signal, and a periodicity of the reference signal in time domain is less than or equal to the PRI. The second communication apparatus sends the reference signal to the first communication apparatus based on the first information. Correspondingly, the first communication apparatus receives the reference signal from the second communication apparatus. The first communication apparatus senses a to-be-sensed target based on the reference signal.

摘要： This application discloses a channel sense method, a network side device, and a terminal, and relates to the field of wireless communications technologies. The method includes: determining, by a network side device, a first sense resource used by a terminal to perform channel sense, where the first sense resource is another resource other than a resource that is in a cell in which the terminal is located and that is used by each terminal to perform data transmission; and sending, by the network side device, first sense indication information to the terminal, where the first sense indication information is used to indicate the first sense resource. To be specific, when the terminal performs sense on the first sense resource, another terminal in a same cell does not receive or send data on the first sense resource. If the terminal senses an interference signal, it can be determined that the interference signal is not an interference signal generated when the another terminal in this cell performs data transmission. Therefore, the channel sense performed by the terminal can be prevented from being interfered with by the data transmission performed by the another terminal in the same cell, thereby improving accuracy of a sense result.

摘要： This application provides a signal transmission method and apparatus, to implement phase tracking in a DFT-S-OFDM system. The method includes: A transmit end determines a guard interval sequence based on a quantity of channel bondings and a quantity of subcarriers corresponding to a resource element of the channel bonding; and then the transmit end sends a signal, where the signal includes the guard interval sequence, and the guard interval sequence is used to determine phase noise of the signal. In other words, in the DFT-S-OFDM system, a guard interval sequence of a sent signal or a received signal is determined based on a quantity of channel bondings and a quantity of subcarriers corresponding to a resource element of the channel bonding, and phase tracking may be implemented in the DFT-S-OFDM system. Therefore, phase noise of the signal can be determined in the DFT-S-OFDM system.
