Problems solved by technology

[0004] However, in many scenarios, the base station cannot know whether the neighboring cell on a certain frequency is synchronized with the serving cell where the UE is located, and cannot provide synchronization indication information for the UE. As a result, even if the neighboring cell and the serving cell are synchronized, the UE cannot obtain Synchronization indication information still needs to read the NR-PBCH of the neighboring cell, which introduces a large measurement overhead

Embodiment Construction

[0042] In many scenarios, because the base station cannot know whether the adjacent cell on a certain frequency is synchronized with the serving cell where the UE is located, it cannot provide synchronization indication information for the UE. As a result, even if the adjacent cell and the serving cell are synchronized, the UE cannot obtain synchronization. For the indication information, it is still necessary to read the NR-PBCH of the neighboring cell, which introduces a large measurement overhead.

[0043] In the embodiment of the present invention, by sending the RRC indication signaling to the UE, requesting the UE to report the synchronization information of the neighboring cell, and then receiving the UE reporting the synchronization information of the neighboring cell through the RRC signaling, the base station can know the synchronization information of the neighboring cell, thereby reducing the number of subsequent UEs. measurement overhead.

[0044] In order to make...

Abstract

The invention relates to methods for obtaining and reporting neighbourhood synchronization information, a base station, user equipment (UE) and a medium. The method for obtaining the neighbourhood synchronization information comprises the steps of: sending RRC indication signalling to the UE, and requesting the UE for reporting the neighbourhood synchronization information, wherein the RRC indication signalling includes the content of the neighbourhood synchronization information reported by the UE; and receiving the content of the neighbourhood synchronization information reported by the UE through the RRC signalling. By adoption of the scheme, the base station can obtain the neighbourhood synchronization information for a subsequent measurement configuration process; and thus, the measurement overhead can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a method for acquiring and reporting synchronization information of adjacent cells, a base station, user equipment and a medium. Background technique [0002] With the development of wireless communication technology, 3GPP has introduced a new radio (New Radio, NR) technology. In the NR system, a cell can contain one or more synchronization signal blocks (SS blocks), that is, one or more beams (beams), and each SS block contains a primary synchronization signal (NR-Primary Synchronization Signal, NR-PSS ), a secondary synchronization signal (NR-Secondary Synchronization Signal, NR-SSS) and a broadcast channel (NR-Physical BroadcastChannel, NR-PBCH). When a cell includes multiple different SS blocks, the multiple different SS blocks can form a synchronization signal burst set (SS burst set). The SS burst set is sent periodically, and the sending cycle can ...
