Abstract: This application provides example uplink carrier handover methods, network devices, and terminal devices. One example method includes obtaining, by a network device, target measurement information, where the network device communicates with a terminal device in a current cell by using a first uplink carrier and a second uplink carrier. The network device can then determine, based on the target measurement information, whether the terminal device needs to be handed over from the first uplink carrier to the second uplink carrier. In response to determining that the terminal device needs to be handed over from the first uplink carrier to the second uplink carrier, the network device can send handover instruction information to the terminal device.

Abstract: A time of flight (TOF) measurement method and apparatus are provided, including a controller, a time to digital converter, a pulse transmitter, and a pulse receiver. The controller is configured to control, in a working period according to a predetermined transmit rule, the pulse transmitter to sequentially send M transmit pulses. The pulse receiver is configured to receive N feedback pulses in the working period. The time to digital converter is configured to obtain time of flight information corresponding to the N feedback pulses. The controller is further configured to obtain a target time of flight based on the time of flight information corresponding to the N feedback pulses, and obtain a target distance based on the target time of flight.

Abstract: Embodiments of this application relate to the communications field, and provide a method and an apparatus for data transmission in multiple carriers. Uplink access carriers may be dynamically adjusted when the uplink load is heavy. The method includes receiving, by a terminal device, at least one piece of indication information from an access network device, where the at least one piece of indication information indicates at least one access control parameter. The method further includes selecting, by the terminal device, an access carrier from at least two candidate carriers based on the at least one access control parameter, where the at least two candidate carriers are in different frequency bands.

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.
