Abstract: The present invention discloses a method and an apparatus for data transmission. The method includes: determining a quantity N of first virtual resource blocks VRBs corresponding to first user equipment UE, where the N first VRBs correspond to N virtual subbands for carrying to-be-transmitted data of the first UE, and N is a natural number greater than or equal to 1; determining, based on the quantity N of the first VRBs, a first step corresponding to the N first VRBs, where the first step is used to indicate a distance between two adjacent physical subbands to which the N first VRBs are mapped in a physical resource, and the first step is greater than 1; and determining, based on the first step, N first PRBs corresponding to the N first VRBs, where the N first PRBs correspond to N physical subbands for carrying the to-be-transmitted data.

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: Embodiments of this application provide a transmission path switching method and apparatus. When a transmission path is switched, a currently used data transmission path is not directly switched from a first transmission path to a second transmission path after the second transmission path is configured, but after it is further determined that a first condition is met, the currently used data transmission path is switched from the first transmission path to the second transmission path, to avoid data interruption in a process of switching a data transmission path of an application from the first transmission path to the second transmission path. This improves use smoothness of the application.

Abstract: First configuration information is configured for a second device by a first device. The first configuration information is used to indicate a first time-frequency resource allocated by the first device. The first time-frequency resource is different from a second time-frequency resource that is allocated by the first device to a third device in a same group. The first time-frequency resource comprises a third time-frequency resource and a fourth time-frequency resource. The third time-frequency resource is a time-frequency resource used when the first device receives a message sent by the second device. The fourth time-frequency resource is a time-frequency resource used when the first device sends a message to the second device. The third time-frequency resource is different from the fourth time-frequency resource. Control information that includes the first configuration information is sent by the first device.

Abstract: Embodiments of the present invention disclose a communication method and a communications apparatus. In the communication method, a network-side device determines a resource configuration policy. The network-side device determines an operation mode of a terminal based on the resource configuration policy; broadcasts information about a plurality of configured resource pools and the operation mode, so that the terminal performs sending based on the configured one or more resource pools; and determines, based on the operation mode, that the terminal sends information on one or more resource units of the plurality of resource pools. According to the communication method and the communications apparatus provided in the specific embodiments of the present invention, the one or more resource pools are configured for a plurality of carriers for inter-terminal communication, so that the terminal can send a message on the one or more resource pools of the plurality of carriers.

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.
