Abstract

The invention discloses a multi-synchronization channel sending and receiving method and device and a medium, which are used for supporting sending and receiving of a plurality of synchronization channels in one bandwidth. According to the multi-synchronization channel sending method, a system bandwidth supports a plurality of synchronization channels in a frequency domain, and the interval between every two adjacent synchronization channels is positive integer times of the bandwidth occupied by at least one resource block (RB); The method comprises the step of sending frequency domain position information of a plurality of synchronous channels in the system bandwidth to user equipment UE. The synchronous channel receiving method comprises the steps that frequency domain position information of a plurality of synchronous channels in a system bandwidth sent by a network side is received, and the interval between every two adjacent synchronous channels is a positive integer multiple of the bandwidth occupied by at least one resource block RB.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a multi-synchronous channel sending and receiving method, device and medium. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] A synchronization channel (SCH, Synchronization Channel) provides key time and frequency domain synchronization data for user equipment (UE, User Equipment). The information on the synchronization channel contains the information necessary for the UE to calibrate the time, and also contains network air interface corrections, receiving system information, and so on. At present, in various 5G systems, the synchronization channel is designed based on a synchronization burst on the air interface, and each synchronization burst contai...
