Abstract

The invention provides a measurement synchronization method, network equipment and terminal equipment, which are used for improving the reliability of measurement synchronization. The method comprisesthe following steps: determining time delay related parameters, wherein the time delay related parameters are used for representing the time delay of a satellite service link corresponding to a service cell and a satellite service link corresponding to an adjacent cell; adjusting a measurement window according to the time delay related parameters, wherein the measurement window is obtained from ameasurement interval parameter configured by network equipment; and measuring the synchronization signal block corresponding to the neighbor cell according to the adjusted measurement window.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a measurement synchronization method, network equipment and terminal equipment. Background technique [0002] In the new radio (NR) measurement synchronization mechanism, the terminal device obtains the synchronization measurement timing configuration (Synchronization Measurement Timing Configuration, SMTC) of the target measurement cell, and quickly locates the frequency point of the target measurement cell according to the measurement window configured in the SMTC The synchronization signal block (Synchronization Signal Block, SSB) completes the process of downlink synchronization with the target measurement cell. [0003] In the satellite communication system, there is a large delay in the satellite service link. Therefore, if the terminal device still measures the SSB according to the measurement window in the SMTC in the satellite communication system, t...
