Title:
METHOD AND APPARATUS FOR USE IN USER EQUIPMENT IN WIRELESS COMMUNICATION, AND METHOD AND APPARATUS FOR USE IN BASE STATION IN WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2020/088212
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and an apparatus for use in a user equipment in wireless communication, and a method and an apparatus for use in a base station in wireless communication. The user equipment receives first signaling and transmits a first wireless signal, wherein the first signaling comprises scheduling information of the first wireless signal; a first reference signal is used for determining at least one of a transmission power of the first wireless signal and a transmission antenna port of the first wireless signal; a first air interface resource is associated with the first reference signal; the first air interface resource is related to the first signaling; the first signaling does not include a first domain; the first domain indicates a transmission antenna port of a wireless signal scheduled by signaling of the first domain. In the case where one UE is served by multiple TRPs/panels, the method ensures the reliability of uplink transmission for any TRP/panel.
