Method for transmission of synchronization signal block, measurement of cell quality, base station, and terminal

Abstract

The invention provides a method for the transmission of a synchronization signal block, a measurement of the cell quality, a base station, and a terminal. The transmission method comprises the step ofsending the synchronization signal block. The synchronization signal block comprises a primary synchronization signal, a secondary synchronization signal, and a physical broadcast channel; wherein the unoccupied positions, which are not occupied by the primary synchronization signal, the secondary synchronization signal, and the physical broadcast channel, in the synchronization signal block arenot used for the data transmission. According to the method for the transmission of the synchronization signal block, the measurement of the cell quality, the base station, and the terminal, in orderto prevent the terminal from being scheduled to the unoccupied positions of the synchronization signal block after the switching is completed, the embodiment sets the unoccupied positions of the synchronization signal block to not be used for the data transmission, so that the quality of the cell measured by the terminal according to the synchronization signal block, is closer to the cell qualityactually in the cell by the terminal, and the accuracy of the cell quality measurement is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission of synchronous signal blocks, a method for measuring cell quality, a base station and a terminal. Background technique [0002] In the existing LTE (Long Term Evolution) technology, the terminal equipment UE performs RRM (Radio Resource Management, radio resource management) measurement based on the cell reference symbol (CRS). Perform handover decision and mobility management. [0003] In LTE, CRS is sent in full bandwidth. In order to reduce the overhead of reference symbols, there will be no CRS in 5G, so there is no need to use other reference signals to replace the CRS measurement function. One of the possible ways is to use synchronization symbols for measurement. The transmission method of synchronization symbols in 5G is as follows: figure 1 Shown: the synchronization symbol and the physical broadcast channel PBCH are transmitted in the SS...
