Title:
METHOD AND APPARATUS USED IN USER EQUIPMENT FOR WIRELESS COMMUNICATION, AND METHOD AND APPARATUS USED IN BASE STATION FOR WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2020/147553
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and apparatus used in a user equipment for wireless communication, and a method and apparatus used in a base station for wireless communication. A user equipment receives first signaling, and sends a first wireless signal group. The first wireless signal group carries a first bit block, and the first wireless signal group comprises K wireless signals; if K is greater than 1, time domain resources occupied by the K wireless signals are orthogonal to each other in pairs; the first signaling comprises a first domain, the first domain in the first signaling indicates a first matrix, and the first matrix is used for determining a pre-coding matrix of the first wireless signal group; the interpretation of the first domain in the first signaling is related to K. The above method supports multiple repeated transmissions of sending one TB by using different pre-coding matrices to improve reliability, and also reduces signaling overhead and the impact on standards to the greatest extent.
