Abstract

The invention provides a resource selection method and device. The resource selection method comprises the following steps that: user equipment (UE) receives a transmission configuration indication state TCI state of a downlink configured by network side equipment, wherein the TCI state at least comprises a plurality of pieces of quasi co-located QCL information, and the plurality of pieces of QCLinformation at least comprise a reference signal RS and a QCL type corresponding to the RS; and the UE selects an RS for performing radio link detection (RLM) according to the RS and / or the QCL typein the plurality of pieces of QCL information. According to the method and the device, the problems of high measurement complexity and power consumption caused by the fact that the UE cannot select aproper RS to perform RLM (Reference Signal) to detect all RSs in a plurality of TCI states in the prior art are solved, and the effect of reducing the measurement overhead of the UE is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a resource selection method and device. Background technique [0002] With the continuous advancement of radio technology, a large number of various radio services have emerged, and the spectrum resources on which radio services rely are limited. Facing the continuous increase in people's demand for bandwidth, traditional commercial communications mainly use 300MHz~3GHz Spectrum resources are extremely tense, which cannot meet the needs of future wireless communications. [0003] In the future wireless communication, it will be extended to support carrier frequencies higher than those used in the fourth generation (4G) communication system, such as 28GHz, 45GHz, etc., and the potential operating frequency band of the system will reach 100GHz. In the high frequency band (greater than 6GHz), due to the large attenuation of electromagnetic waves, beamforming methods are usually r...
