Abstract: This application provides a method for determining a sidelink DRX configuration and a communication apparatus. The method includes: determining at least two PQIs or sidelink QoS profiles corresponding to a service of a terminal, then determining at least two sidelink DRX configurations corresponding to the at least two PQIs or sidelink QoS profiles, and then determining a sidelink DRX configuration for use based on the at least two sidelink DRX configurations. In this way, an appropriate sidelink DRX configuration can be determined for use, to help improve efficiency of communication between terminals. In addition, when a terminal on a transmitter side and a terminal on a receiver side each determine a sidelink DRX configuration for use according to the method, both the terminal on the transmitter side and the terminal on the receiver side use a same sidelink DRX configuration.

Abstract: This application provides a method that includes the step of receiving, by a first device in a first time domain position, first scheduling information. The first scheduling information includes first indication information sent by a network device, wherein the first indication information is used to indicate a first interval. The method further comprises sending, by the first device, second scheduling information including second indication information to a second device in a second time domain position, wherein the second indication information is used to indicate a second interval, which is the difference between the first interval and a third interval. The second scheduling information is used by the second device to determine that-the target time domain position used by the second device to determine a time domain resource used to send and/or receive data.

Abstract: A method for monitoring a communications channel between a terminal device and a network device is described. The method includes: obtaining a first search space configuration and a second search space configuration. The first search space configuration includes a first search space set and the second search space configuration includes a second search space set, or the first search space configuration includes a first search space parameter and the second search space configuration includes a second search space parameter. The method further includes monitoring a physical downlink control channel (PDCCH) based on the first search space configuration if a first condition is met. The first condition includes: a first timer is not in a running state; or monitoring, by the terminal device, a PDCCH based on the second search space configuration if a second condition is met. The second condition includes a first timer is in a running state.

Abstract: Embodiments of the present invention provide an uplink subcarrier spacing indication method, a base station, and a terminal. The base station determines indication information that is used to indicate a first uplink subcarrier spacing supported by the base station, and communicates with the terminal according to the indication information. During the communication, the base station indicates the first uplink subcarrier spacing supported by the base station to the terminal, so that the terminal subsequently determines, based on the first uplink subcarrier spacing, a second uplink subcarrier spacing supported by the terminal; or the base station receives information that is sent by the terminal and that carries a second uplink subcarrier spacing, in other words, receives an indication from the terminal, so as to learn of the second uplink subcarrier spacing supported by the terminal or to be used by the terminal to send an uplink signal.
