Title:
USER EQUIPMENT USED IN WIRELESS COMMUNICATION, METHOD IN BASE STATION AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/119197
Kind Code:
A1
Abstract:
Disclosed are user equipment used in wireless communication, method in base station and device. The user equipment firstly receives a target wireless signal, then transmits a first wireless signal in a first time resource pool, and monitors a first signaling in a second time resource pool located on a first frequency domain resource. A channel measurement for the target wireless signal is used to trigger transmission of the first wireless signal. The first signaling is sent using a first antenna port group, and the first wireless signal is used to determine a second antenna port group. The first antenna port group and the second antenna port group are different. The first signaling is a physical layer signaling, and the first signaling is used to determine whether the first wireless signal is correctly received. By designing the first signaling, the present application implements a more efficient management of beam over the unlicensed spectrum, and improves overall system transmission efficiency and performance.
