Abstract: The present disclosure relates to delay measurement methods and apparatus. In one example method, a first communications device receives a data unit from a second communications device, where the data unit includes time information, the time information is used to indicate a first moment at which the second communications device sends the data unit, and the time information indicates the first moment based on a part of bits of a frame number. The first communications device determines a delay from the second communications device to the first communications device based on the first moment and a second moment, where the second moment is a moment at which the first communications device receives the data unit.

Abstract: Embodiments of this application provide a communications method and apparatus. The method includes: determining a target cell based on measurement results of N measured cells and a preset value when there is a first cell satisfying a report trigger condition; and sending a measurement result of the target cell to a base station. Based on the foregoing technical solution, the terminal may not only send the measurement result of the cell satisfying the trigger condition to the base station, but also send a measurement result of another cell to the base station. In this way, a quantity of cells that can be selected during determining of handover can be increased, to help the base station select a suitable cell for the terminal.

Abstract: A communications method and apparatus. The communications method includes: transmitting a first request to a network device through a first resource, where the first request is used to request beam failure recovery of a first cell or is used to request system information of the first cell, the first resource is a resource of a second cell, and the first cell and the second cell are serving cells of a same terminal; and receiving a first response corresponding to the first request from the network device. Therefore, when a terminal has a plurality of serving cells, the terminal may transmit a request across cells (or across carriers), to improve transmission reliability.

Abstract: In the embodiments of the present invention, UE can complete, by using only two interaction steps instead of six steps in the prior art, a process of sending a data packet to an eNodeB. Even a random access process in the six steps in the prior art includes four interaction steps, and by contrast, in the embodiments, signaling that needs to be consumed on an eNodeB when the UE sends data can be significantly reduced. This is relatively suitable for a scenario in which small data or occasional data is sent.
