Title:
TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2024/069822
Kind Code:
A1
Abstract:
A terminal according to one aspect of the present disclosure comprises: a transmission unit which, on the basis of at least one of a synchronization status for each of transmission-reception points (TRPs) and establishment of a time alignment for each of the TRPs, uses a specific uplink (UL) signal to transmit a UL time synchronization request pertaining to the TRP; and a control unit which, after a specific period of time has elapsed from transmission of the UL signal, determines that a plurality of TRPs have been synchronized. One aspect of the present disclosure makes it possible to appropriately carry out communication even when the communication is carried out using a plurality of transmission points.
