Title:
WIRELESS BASE STATION AND WIRELESS TERMINAL
Document Type and Number:
WIPO Patent Application WO/2021/176783
Kind Code:
A1
Abstract:
The present invention easily executes phase tracking when a plurality of wireless base stations are simultaneously performing transmission. According to the present invention, a wireless base station performs cooperative transmission to a wireless terminal in cooperation with a cooperating wireless base station. The wireless base station comprises a wireless control unit and a communication unit. The wireless control unit selects a reference signal with the cooperating wireless base station that is to perform the cooperative transmission and generates the selected reference signal. The communication unit transmits a signal that includes the reference signal to the wireless terminal in cooperation with the cooperating wireless base station. On the basis of the reference signal received, the wireless terminal estimates the frequency error between the wireless base stations performing the cooperative transmission.
