Embodiment Construction

[0081] In the 5G system, the synchronization signal, the physical broadcast channel is transmitted in the SynchronizationAl-block, SS-Block, and introduces the function of the scanning beam. Each synchronization signal block can be considered a resource of a beam (analog domain) during the beam Sweeping process, the scanning process, which is repeatedly transmitted on different beams of the synchronization signal block. By sweeping the beam training, the user equipment can sense the strongest signal received on which beam.

[0082] Among them, the primary synchronization signal (PSS), a secondary Synchronization Signal, SSS, and Physical Broadcast Channel (PBCH) is in the synchronous signal block. Multiple synchronization signal blocks form a synchronization signal burst, and the synchronization signal burst can be considered a relatively concentrated a plurality of beams, and multiple synchronization signal bursts Synchronization Signal-Burst-set, SS-BURST-SET.

Abstract

A CSI-RS configuration method and device, a computer-readable storage medium, a base station, and a user equipment, the method comprising the following steps: determining a cell-level CSI-RS; sending index information of a synchronization signal block to the user equipment, so that all The user equipment determines the time-frequency position of the CSI-RS based on the index information; wherein, the index information of the synchronization signal block and the time-frequency position of the CSI-RS have a predefined correspondence. The solution of the present invention enables the base station to send a small number of bits of information to enable the user equipment to determine the time-frequency position of the CSI-RS, thereby realizing efficient configuration of the CSI-RS.

Description

Technical field [0001] The present invention relates to communication technologies, and in particular to a CSI-RS configuration method and device, a computer-readable storage medium, the base station, the user equipment. Background technique [0002] 5G in the system, the synchronization signal, a physical broadcast channel signal block synchronization is transmitted, and introduces beam sweep function. Each synchronization signal as a resource block may be a beam sweeping beam (beam sweeping) process (analog domain), the sweep beam of the process is the process of repeated block synchronization signal transmitted on a different beam. Sweeping the beam through training, a user may perceive a signal device on which the strongest received beam. [0003] Block synchronization signal beam generally wide beam is used, the user equipment in the idle state for which the antenna gain is sufficient. However, for a user equipment connected state which the antenna gain is not enough, usuall...
