Embodiment Construction

[0031] It is proposed in the discussion of 3GPP Rel-14 that the UE implements synchronization with the base station through a synchronization signal, and the composition of the synchronization signal includes at least a primary synchronization signal and a secondary synchronization signal. At the same time, in the 3GPP Rel-14 discussion, it is considered to present the synchronization signal in the form of a synchronization signal block, and it is considered to introduce beam scanning (Beam Sweeping) into the wireless communication system to scan each beam in the time domain. And this scanning will cause the beam scanning of the primary synchronization signal and the secondary synchronization signal in the synchronization signal block on each beam, which will cause the UE to confuse the timing of the synchronization signal block, that is, the UE will know the synchronization signal block sequence number and the synchronization signal block. Uncertainty arises from positional ju...

Abstract

The invention relates to a method for processing synchronous signal blocks, a base station and user equipment. The synchronous signal blocks include first synchronous signal subblocks and second synchronous signal subblocks. In each synchronizing cycle, the method comprises the following steps: sending the first synchronous signal subblocks corresponding to all wave beams in the synchronizing cycle according to a preset first wave beam scanning sequence; and sending the second synchronous signal subblocks corresponding to all wave beams in the synchronizing cycle according to a preset second wave beam scanning sequence, wherein the first wave beam scanning sequence and the second wave beam scanning sequence are different, and therefore, relative offsets of the time domain between each first synchronous signal subblock and the corresponding second synchronous signal subblock are different. By utilizing the scheme, the processing complexity of the synchronous signal blocks can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for processing synchronous signal blocks, a base station and user equipment. Background technique [0002] In a Long Term Evolution (Long Term Evolution, LTE) communication system, a user equipment (User Equipment, UE) implements time synchronization with a base station (Base Station, BS) through a synchronization signal. This is because the synchronization signal includes at least a primary synchronization signal (Primary Synchronization Signal, PSS) and a secondary synchronization signal (Secondary Synchronization Signal, SSS). Under the premise of a clear duplex mode, the difference between PSS and SSS in the time domain of the system frame The position is fixed, and after the UE detects the PSS and SSS, it can obtain the positions of the PSS and SSS in the system timing to realize time domain synchronization with the base station. [0003] The above-m...
