Title:
UPLINK TRANSMISSION METHOD, USER EQUIPMENT, BASE STATION, AND COMPUTER READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/032637
Kind Code:
A1
Abstract:
The present disclosure provides an uplink transmission method, and a corresponding user equipment, base station and computer readable medium. A method for an uplink data transmission includes: determining a transmission occasion for an uplink transmission and a Hybrid Automatic Repeat Request, HARQ, process ID corresponding to the transmission occasion; determining an antenna port according to a correspondence between antenna ports and HARQ process IDs and/or a correspondence between antenna ports and transmission occasions; and transmitting, by the antenna port, uplink data corresponding to the HARQ process ID and a pilot signal corresponding to the uplink data. By establishing the correspondence between the antenna ports and the HARQ process IDs or the transmission occasion, the base station determines the antenna port when detecting the uplink transmission, so that the HARQ process ID corresponding to the uplink transmission may be determined.
