Abstract: Aspects of the disclosure can provide a data transmission method implemented by a second access network device that can include receiving transmission status indication information sent by a first access network device. The transmission status indication information includes beam occupation information and cycle occupation information. The method can further include determining a second beam having a mutually exclusive interference relationship with the first beam, determining, when the second access network device needs to perform transmission of second data with a second terminal by using the second beam, a fixed cycle occupied by the second data based on the fixed cycle occupied by the first data, and performing transmission of the second data with the second terminal in the fixed cycle occupied by the second data.

Abstract: A method, an apparatus, a user equipment and a base station are provided for implementing location area update. In the method, the UE obtains a judgment result by determining whether there is data to be transmitted currently, when a radio access network-based location area update (RLAU) is triggered, where the data to be transmitted is one of service data and signaling data. The UE determines a second message based on the judgment result and a first message, where the first message is an original connection resume request message, and the second message carries a cause value requesting for resuming connection. The UE transmits the second message to the base station.
