Abstract

The disclosure relates to a method and device for processing PBCH bandwidth, a base station, and a computer-readable storage medium. Wherein, the processing method of the PBCH bandwidth includes: judging whether the current frequency band is a preset type frequency band, wherein, the preset type frequency band can use two kinds of subcarrier spacing SCS; if the current frequency band is a preset type frequency band, then reducing The number of PBCH information bits contained in the load and the number of resource elements RE occupied by the demodulation reference signal DMRS in the synchronization signal block SSB corresponding to the current frequency band remain unchanged, or the number of PBCH information bits contained in the load in the PBCH corresponding to the current frequency band remains unchanged. Change and reduce the number of REs occupied by DMRS in the SSB corresponding to the current frequency band. The embodiments of the present disclosure can solve the problem that the UE takes too long to search for the synchronization signal.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a physical broadcast channel (PBCH) bandwidth processing method and device, a base station, and a computer-readable storage medium. Background technique [0002] In the recent 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) discussion, it is proposed that some frequency bands need to use two types of subcarrier spacing (SCS). The synchronization grid will become very small because these frequency bands may be relatively narrow. At the same time, after the minimum bandwidth of the user equipment (UE) is determined, the number of synchronization signal detection attempts will be large. In some extreme cases, the UE searches for the synchronization signal. The time is as long as 15 minutes, which is unacceptable to UE. Contents of the invention [0003] In view of this, the present application discloses a PBCH bandw...
