Abstract: Embodiments of the present application provide a data transmission method, and the method is used for communication between UE and a base station on an unlicensed spectrum. The method includes: sending, by the UE, a data packet to the base station and starting a timer during a current COD of the base station; determining a first end moment of the current COD; pausing the timer at the first end moment; determining a second end moment of an LP in a next COD of the base station; resuming the timer at the second end moment; and receiving, before the resumed timer expires, a response message from the base station. In the embodiments of the present application, the UE suspends the timer at the end moment of the previous COD and resumes the timer at the end moment of the LP of the next COD.

Abstract: A resource scheduling method includes: obtaining, by a terminal device, a first resource configuration parameter from an access network device; determining, by the terminal device, whether a first logical channel (LCH) supports the first resource configuration parameter, where the first LCH is an LCH on which there is to-be-sent data; and if the first LCH supports the first resource configuration parameter, determining, by the terminal device, a resource of the first LCH based on the first resource configuration parameter. According to a resource scheduling method provided in this application, after obtaining the first resource configuration parameter, the terminal device determines the resource of the first LCH by determining whether a mapping relationship exists between the first LCH and the first resource configuration parameter, to map the first LCH to the resource that matches the first LCH. This improves resource utilization.
