Abstract

The invention provides a method for generating downlink synchronizing signals and a base station. The method for generating the downlink synchronizing signals is applied to the base station. The method comprises the following steps: partitioning system frequency resources into a plurality of frequency bands; selecting a segment of frequency resources from each of the frequency bands respectively to serve as basic bandwidth areas; partitioning the frequency bands into wireless frames respectively; and generating the downlink synchronizing signals in the wireless frames in the basic bandwidth areas of the frequency bands respectively. Through the technical scheme, generation of the downlink synchronizing signals in a communication scene in which a broadband system and a narrowband system coexist can be finished.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for generating a downlink synchronization signal and a base station. Background technique [0002] In a communication system, the information receiver and the information sender must ensure that they are synchronized in time before information can be transmitted. If the synchronization error between the sending and receiving parties is too large, it will directly affect the performance of the communication system, and even cause the communication system to be paralyzed. Therefore, the synchronization technology is very important for the communication system, and the transmission of the synchronization signal is the basis for the normal operation of the communication system. [0003] In the Long Term Evolution (LTE) system, the downlink synchronization signal occupies the positions of the middle 6 physical resource blocks of the system bandwidth, that is...
