Abstract

The invention discloses a transmission method of a synchronous access signal block, network side equipment and a user terminal. The method comprises the following steps: acquiring a synchronous accesssignal set, wherein the synchronous access signal set comprises multiple synchronous access signal blocks, each synchronous access signal lock comprises PSS, SSS and PBCH signals, each PBCH signal comprises MIB, the MIB comprises serial number information, and the serial number information is used for representing a serial number of the synchronous access signal block located by the MIB in the synchronous access signal set; and respectively sending different synchronous access signal blocks in the synchronous access signal set on different time resources by using different wave beams. Therefore, the user terminal can perform the time synchronization by using the serial number information of the synchronous access signal. The time synchronization accuracy can be improved through the transmission method disclosed by the embodiment of the invention.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for transmitting synchronous access signal blocks, network side equipment and user terminals. Background technique [0002] At present, the millimeter wave band (6-100GHz) has attracted much attention due to its advantages of rich spectrum resources and wide transmission bandwidth, and has become an essential technology for future communication system (eg 5G) standards. However, a prominent shortcoming of millimeter wave technology is that the path loss is very large, and, as the frequency increases, the path loss increases, which leads to a small coverage area of ​​the narrow beam of the millimeter wave band. [0003] In the existing communication system, the base station repeatedly sends the same synchronous access signal at different times using different beams, and different beams cover different areas, so as to realize the broadcast function and expan...
