Abstract

The invention discloses a method and terminal for transmitting hybrid automatic repeat request acknowledgement (HARQ-ACK) messages. The method comprises the following steps of determining the reservedresources for transmitting the HARQ-ACK messages in an uplink transmission channel; and punching at least part of resources in the reserved resources, and transmitting the HARQ-ACK message through the punched resources. According to the invention, the terminal determines the reserved resources used for transmitting HARQ-ACK messages; at least part of the reserved resources are selected for punching; the HARQ-ACK message is transmitted through the reserved resources, and the CSI-part1 is transmitted through other resources except the reserved resources, so that the resource conflict problem ofthe HARQ-ACK message and the CSI information is avoided, and the transmission of the HARQ-ACK message does not affect the transmission of the CSI information.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission method and terminal of a hybrid automatic repeat request response message. Background technique [0002] Compared with previous mobile communication systems, the future fifth generation (5 th Generation (5G) mobile communication system, or New Radio (NR) system, needs to adapt to more diverse scenarios and business requirements. The main scenarios of 5G include mobile broadband enhanced eMBB, large-scale Internet of Things mMTC, and ultra-reliable and ultra-low-latency communication uRLLC. These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage. In order to meet different needs of services and different application scenarios, the subcarrier spacing of the NR system is no longer the same as that of the traditional fourth generation (4 th Generation, 4G), or long-term evoluti...
