Title:
BASE STATION, TERMINAL, WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/217542
Kind Code:
A1
Abstract:
A terminal (200) comprises: a reception unit (212) that receives a signal of a random access procedure from a base station (100); a control unit (220) that controls a transmission timing of transmitting the signal of the random access procedure; and a transmission unit (211) that transmits the signal of the random access procedure to the base station (100) in an unlicensed band at the transmission timing controlled by the control unit (220). The base station comprises: a transmission unit that transmits the signal of the random access procedure; and a reception unit (112) that receives the signal of the random access procedure. The control unit (220) controls the transmission timing of the signal of the random access procedure that is transmitted from the transmission unit (211) in accordance with configuration information (T) related to the transmission timing.
