Embodiment Construction

[0039] The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

[0040]Before introducing the embodiments of the present application, the problems of the prior art are first described. In earlier 3GPP protocol versions, if HARQ-ACK resources with different priorities overlapped, the transmission of HARQ-ACK with low priority would be discarded. Based on this, in order to improve the flexibility of network scheduling, different priorities were proposed. When the resources of the HARQ-ACK of the different stages overlap, the resources are multiplexed for transmission. If HARQ-ACKs with different priorities are multiplexed and transmitted on the same PUCCH, and the total uplink control information (UCI) bits are greater than 2, the two groups of HARQ-ACKs can be encoded independently or jointly After encoding, it is transmitted on the PUCCH, and t...

Abstract

The embodiment of the invention provides an HARQ-ACK (Hybrid Automatic Repeat reQuest Acknowledgement) transmission method and device, user side equipment and a storage medium, relates to the technical field of communication, and can improve the transmission performance of HARQ-ACK when HARQ-ACK resources with different priorities are overlapped. The HARQ-ACK transmission method comprises the following steps: in a plurality of pieces of downlink control information DCI corresponding to at least one cell and used for indicating the same uplink slot, at least part of fields in the last piece of high-priority DCI are acquired, and the at least part of fields are used for indicating a total downlink assignment index DAI of specified low-priority DCI; generating a codebook with a high priority, and generating a codebook with a low priority according to the total DAI of the specified DCI with the low priority; according to the codebook with the low priority and the codebook with the high priority, encoding the HARQ-ACK with the low priority and the HARQ-ACK with the high priority; and transmitting the coded HARQ-ACK (Hybrid Automatic Repeat Request Acknowledgement) with the low priority and the coded HARQ-ACK with the high priority.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a hybrid adaptive repeat request (Hybrid Automatic Repeat Request, HARQ)-acknowledgement (Acknowledgement, ACK) transmission method, device, user-side equipment, and storage medium. Background technique [0002] In the 3rd Generation Partnership Project (3GPP) protocol version-16 (Release-16), the base station can configure the radio resource control (Radio Resource Control, RRC) signaling with the physical layer downlink shared channel (physical layer). A field in the downlink share channel (PDSCH) configuration (PDSCH-Config) to indicate the physical uplink control channel (PUCCH) of the physical layer carrying HARQ-ACK corresponding to the PDSCH scheduled by downlink control information (DCI) priority. For example, the priority of the HARQ-ACK may be indicated by a certain field of the DCI. When the resources of the HARQ-ACK of different priorities ove...
