Abstract

The invention provides a method for transmitting hybrid automatic repeat request (HARQ) feedback information and a communication device. Terminal equipment receives K downlink data channels, each downlink data channel in the K downlink data channels has a corresponding transmission parameter group, and at least two downlink data channels correspond to different transmission parameter groups; the terminal equipment determines a first transmission resource according to first information comprising M transmission parameter groups, wherein K and M are integers greater than or equal to 2, and the HARQ feedback information corresponding to the K downlink data channels is sent on the first transmission resource, so that smooth feedback of multiple pieces of HARQ feedback information can be realized, and the improvement of the reliability of service transmission is facilitated.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201910364217.3 and the application name "Method and Communication Device for Transmission of Hybrid Automatic Repeat Request HARQ Feedback Information" submitted to the China Patent Office on April 30, 2019, the entire content of which Incorporated in this application by reference. technical field [0002] The present application relates to the communication field, and more specifically, relates to a method and a communication device for transmitting hybrid automatic repeat request (hybrid automatic repeat request, HARQ) feedback information. Background technique [0003] Compared with the previous generations of mobile communication systems, the fifth generation (5G) mobile communication system puts forward higher requirements in terms of transmission rate, delay and power consumption. The International Telecommunication Union (ITU) has defined three application scenari...
