Abstract

The embodiment of the invention discloses a reference signal measurement method, a terminal and network side equipment, which are used for solving the problem that the terminal cannot effectively perform layer 1 measurement on a reference signal of a neighbor cell and is not beneficial to mobility management due to measurement limitation when L1 is lacked to measure the reference signal of the neighbor cell in the related technology. The method comprises the following steps that: the terminal performs layer L1 measurement on a reference signal of a neighbor cell / neighbor transmitting and receiving point (TRP) according to a measurement limiting condition to obtain a measurement result; and the terminal sends the measurement result.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a reference signal measurement method, a terminal and a network side device. Background technique [0002] The existing layer 1 (L1) measurement technology is mainly performed on the reference signal (Reference Signal, RS) of the current cell, and has a series of measurement restrictions. The measurement of the neighboring cell RS can only be performed at layer 3, and is limited to the measurement time configuration. For example, when the RS of the neighboring cell is a synchronization and physical broadcast signal (Synchronization Signal and PBCHblock, SSB), the measurement of the SSB is limited to SSB measurement time configuration (SS / PBCH Block Measurement TimeConfiguration, SMTC). It can be seen that the related art lacks L1 measurement restrictions when measuring RSs in neighboring cells, and the terminal cannot effectively perform Layer 1 measu...
