Abstract: Embodiments of the present invention propose a D2D communications method, apparatus, and system. In the solution, a D2D SPS available period in which a first terminal is capable of using a D2D SPS resource is greater than one SC period. Therefore, in the D2D SPS available period, the first terminal needs to determine the D2D SPS resource only one time, and a second terminal also needs to decode SCI only one time to determine the D2D SPS resource. In this way, the first terminal does not need to determine a D2D SPS resource in each SC period, and the second terminal also does not need to decode SCI in each SC period to determine the D2D SPS resource. Therefore, D2D communication efficiency is improved.

Abstract: A communication method includes reporting fourth and fifth band sets. The fourth band set and the fifth band set include a twelfth band and a thirteenth band. A maximum quantity of layers supported by uplink transmission on the twelfth band of the fourth band set is 1. A maximum quantity of layers supported by uplink transmission on the thirteenth band of the fourth band set is 2. A maximum quantity of layers supported by uplink transmission on the twelfth band of the fifth band set is 2. A maximum quantity of layers supported by uplink transmission on the thirteenth band of the fifth band set is 2. The method also includes receiving fourth information that indicates transmitter (Tx) switching on the twelfth band and the thirteenth band. The method further includes performing Tx switching on the twelfth band and the thirteenth band based on parameters of a sounding reference signal.

Abstract: A communication apparatus includes a first duplexer, a second duplexer, and a switch. In a first switch position, a first output end of the switch is connected to a first branch at which the first duplexer is located. In a second switch position, a second output end of the switch is connected to a second branch at which the second duplexer is located. A transmit filter of the first duplexer corresponds to a first uplink band. A receive filter of the first duplexer corresponds to a first downlink band. A bandwidth of the first downlink band is greater than a bandwidth of the first uplink band. A transmit filter of the second duplexer corresponds to a second uplink band. A receive filter of the second duplexer corresponds to a second downlink band. A bandwidth of the second downlink band is greater than a bandwidth of the second uplink band.
