Terminal capability reporting method and device

Abstract

The embodiment of the invention provides a terminal capability reporting method and device, and the method applied to a network side comprises the steps: transmitting a capability request reporting message to UE in a radio resource control RRC connection state when the network side needs terminal UE to report an unlicensed spectrum access capability; receiving an unlicensed spectrum access capability cell sent by the UE with the unlicensed spectrum access capability according to the capability request report message, wherein the unlicensed spectrum access capability cell comprises unlicensed spectrum access capability information of the UE. According to the embodiment of the invention, the reporting of the unauthorized spectrum access capability of the terminal in 5G is realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for reporting terminal capabilities. Background technique [0002] With the rapid development of the mobile communication industry, especially the rapid growth of mobile Internet services, the contradiction between the increasing spectrum demand and the limited available spectrum has become increasingly prominent. 5G has high data traffic and high transmission rate requirements, and spectrum resources have also become the focus of the 5G era. Therefore, it is necessary to study 5G NR (5G NR inUnlicensed Spectrum, NR-U) working in unlicensed spectrum. [0003] Currently, NR-U deployment scenarios include the following scenarios: Scenario A, carrier aggregation between licensed band NR (primary cell) and NR-U (secondary cell), where the NR-U secondary cell can have both uplink and downlink or only downlink; Scenario B, dual ...

Problems solved by technology

At this stage, there is no mechanism for NR-U UEs to report information about unlicensed spectrum. If the network side cannot know whether the UE supports unlicensed spectrum functions and its specific capabilities, the configuration of the UE on the network side may exceed the upper limit of UE capabilities. And in the scheduling, it is impossible to perform data transmission on one or more carriers corresponding to the licensed spectrum or unlicensed spectrum according to the UE capability, which will affect the base station's control and management of the UE in terms of measurement, mobility management, carrier management, and scheduling. decision making
