Embodiment Construction

[0105] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0106] In the related art, in the 5G unlicensed spectrum system, the system stipulates the maximum number of SSBs (such as 4) that can be transmitted in one transmission period (such as 14 time domain symbols). The base station may determine the actual number of transmitted SSBs (such as 1 or 2) according to actual conditions. The number of SSBs actually transmitted may be relatively small, and...

Abstract

The invention relates to a method and device for transmitting synchronization signal. The method comprises: performing channel detection on the time-frequency resources corresponding to the synchronous broadcast block of the base group to be sent and the synchronous broadcast block of the extended group, respectively, to detect whether the time-frequency resource is idle; the base group and the extended group comprise synchronous broadcast blocks of the same serial number; the synchronous broadcast block of the base group of the same sequence number and the synchronous broadcast block of the extended group correspond to different time-frequency resources; transmitting, when the time-frequency resource corresponding to the at least one synchronous broadcast block in the base group and the extended group is idle, the information block, where the information block includes the at least one synchronous broadcast block.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for transmitting a synchronization signal. Background technique [0002] In related technologies, the industry has recently conducted project research on 5G (5th generation communication system) unlicensed spectrum, and proposed a solution to support separate networking of 5G unlicensed cells. In the design of independent networking of 5G unlicensed spectrum, the first step is to consider the design of SS / PBCH BLOCK (hereinafter abbreviated as SSB). However, there is currently no effective solution in the industry. Contents of the invention [0003] Embodiments of the present invention provide a method and device for transmitting a synchronization signal. Described technical scheme is as follows: [0004] According to a first aspect of an embodiment of the present invention, a method for transmitting a synchronization signal is provided, in...
