Abstract: A method and system for mobility latency reduction in a hierarchical NR architecture is provided. In an embodiment, a method in a network component for handover of a UE includes configuring, by the network component, at least one TRP determined according to UE mobility information. The configuring the at least one target TRP is performed prior to the UE moving into a border area between the at least one target TRP and a first serving TRP. Configuring the at least one target TRP results in the at least one target TRP being configured to act as a secondary serving TRP to the UE. The method also includes configuring at least one target TRP and the UE with corresponding dedicated access resource and monitoring opportunities. The method also includes activating a connection and data communication between the UE and the at least one pre-configured secondary serving TRP.

Abstract: This application provides a communication method, a terminal, and an access network device. The method includes: sending, by a terminal in an RRC inactive state, first information to a first access network device, where the first information is used to indicate that the terminal is located in a wireless network area in which the terminal is in the RRC inactive state, and the first access network device is an access network device to which a cell in which the terminal is currently located belongs; receiving, by the terminal, a first message sent by the first access network device; and remaining, by the terminal, in the RRC inactive state based on the first message, or entering an idle state from the RRC inactive state based on the first message. According to the technical solutions of this application, performance of a communications system can be improved.

Abstract: This application provides a transmission mode switching method and an apparatus. When UE is in a connected state, if an uplink service volume of the UE within a first detection time is less than a first threshold, the UE switches a state from the connected state to an ecology conservation optimization; or switches, in the connected state, a transmission mode from an uplink scheduling-based transmission mode to an uplink contention-based transmission mode.
