Title:
UPLINK TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/048500
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and in particular to an uplink transmission method and apparatus. The solution is applied to a terminal, wherein the terminal is in dual connectivity with a first base station and a second base station; and the terminal communicates with the first base station by means of time division duplex (TDD), and the terminal communicates with the second base station by means of frequency division duplex (FDD). The solution comprises: the terminal acquiring time division multiplexing configuration information, wherein the time division multiplexing configuration information is used for indicating a TDD time domain resource for the communication between the terminal and the first base station; the terminal acquiring TDD time domain resource configuration information of the first base station, wherein the TDD time domain resource configuration information is used for indicating a TDD non-uplink time domain resource; and the terminal determining an FDD uplink time domain resource, and the terminal carrying out uplink transmission with the second base station on the FDD uplink time domain resource.
