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: A grant-free resource configuration method and an apparatus are provided. The method includes: listening to, by a terminal device, a physical downlink control channel on a paging occasion by using a grant-free resource configuration identifier; and obtaining, by the terminal device on the physical downlink control channel or a physical downlink shared channel indicated by the physical downlink control channel, grant-free resource configuration information sent by a network device. In this grant-free resource configuration solution, the terminal device listens to a physical downlink control channel on a same paging occasion by using different identifiers, and obtains grant-free resource configuration information. A configuration occasion is preset, to ensure that the grant-free resource configuration information can be effectively received by the terminal device. In addition, the grant-free resource configuration identifier is used, to facilitate grant-free resource configuration for the terminal device.

Abstract: An embodiment of this application provides a power control method. The method includes: receiving, by a first node from a second node, first power control information associated with a first resource pair link; and sending, by the first node, a first signal to the second node by using a first transmission resource corresponding to the first resource pair link, where transmit power of the first signal is obtained based on the first power control information. An association relationship is established between power control and a resource pair link, so that power control on a resource pair link granularity can be implemented, different power control can be performed based on different channel features, and more accurate transmit power is obtained. In addition, various signals are transmitted on resources corresponding to different resource pair links, so that different power control values can be set for the various signals. In this way, interference can be reduced while correct reception is performed, and a significant gain may be made on network communication quality.
