Abstract: Example communication methods and apparatus are described. One example communication method includes receiving indication information by a terminal device from a network device, where the indication information is used to indicate resource configuration information of a first uplink carrier and/or a second uplink carrier. The first uplink carrier and the second uplink carrier are different uplink carriers in a cell of the network device, and the first uplink carrier and the second uplink carrier are corresponding to one downlink carrier in the cell. The terminal device determines one uplink carrier from the at least one uplink carrier as a target carrier for performing random access based on the resource configuration information of the at least one uplink carrier.

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: Embodiments of this application provide a communication method, a terminal and a base station. The method includes: receiving, by a terminal, a scheduling request resource configuration sent by a base station, where the scheduling request resource configuration indicates an uplink resource type or logical channel information; and sending, by the terminal, a scheduling request to the base station via a target scheduling request resource based on the scheduling request resource configuration and uplink data, where the target scheduling request resource indicates a target uplink resource type, and the scheduling request resource configuration includes the target scheduling request resource. In the embodiments of this application, when diversity of the uplink data is considered, the base station configures different scheduling request resources for different service characteristics, and the terminal selects different scheduling request resources for different service characteristics, to improve effectiveness of uplink service transmission.

Abstract: Embodiments of this application provide a configuration method and apparatus. When indicating, by using an RRC connection release message, a terminal to enter an inactive state from a connected state, a network device may include, in the RRC connection release message, a configuration parameter allocated to the terminal in the inactive state. That is, the terminal receives the radio resource control RRC connection release message sent by the network device, where the RRC connection release message includes first information used to indicate a target configuration parameter. In this way, the terminal may enter the inactive state based on the RRC connection release message, and determine a context parameter of the inactive state based on the first information, so that the configuration parameter is properly allocated to the terminal in the inactive state.

Abstract: This application provides a communications method and apparatus. The method includes: obtaining, by a media access control (MAC) entity, M radio link control (RLC) protocol data units PDUs, where M is an integer greater than or equal to 2; and generating, by the MAC entity, N media access control MAC protocol data units (PDUs) based on a logical channel corresponding to each of the M RLC PDUs, where any two RLC PDUs corresponding to a same logical channel and having consecutive RLC sequence numbers are carried in different MAC PDUs, and N is an integer greater than or equal to 2. Consecutive RLC PDUs are placed into different MAC PDUs, so that a continuous packet loss of a same service can be avoided, and transmission reliability can be improved.
