Title:
USER EQUIPMENT, BASE STATION AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/073862
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce the load on UE and/or delay in a wireless communication system for performing communication using a configuration different from that of an existing LTE system. This user equipment comprises: a reception unit which receives a first synchronization signal (PSS), a second synchronization signal (SSS) and a broadcast channel (PBCH); and a control unit which, in a predetermined block composed of a predetermined number of symbols and a predetermined number of sub-carriers, controls the reception of the PSS and the SSS that are disposed in a first frequency domain, and the PBCH that is disposed in at least part of a second frequency domain wider than the first frequency domain, wherein in the predetermined block, the PBCH is disposed in at least part of a predetermined domain adjacent to the SSS in a frequency direction, and the PBCH is not disposed in a predetermined domain adjacent to the PSS in the frequency direction.
