Embodiment Construction

[0033] As mentioned in the background technology, the current type 3 HARQ ACK codebook does not support the generation of type 3 HARQ ACK CB when there are HARQ ACKs with different priorities.

[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] figure 1 It is a flowchart of a HARQ ACK information feedback method according to an embodiment of the present invention.

[0036] The method for feeding back HARQ ACK information may be used on a user equipment (User Equipment, UE) side, that is, the user equipment may execute each step of the above method.

[0037] The HARQ ACK information feedback method may include the following steps:

[0038] Step S101: receiving downlink control signaling that triggers generation of HARQ ACK information;

[0039] Step S102: Determine the HARQ ACK p...

Abstract

The invention discloses an HARQ ACK information feedback method and device, a storage medium, user equipment and a base station. The HARQ ACK information feedback method comprises the steps: receiving a downlink control signaling for triggering generation of HARQ ACK information; determining HARQ ACK priority indication information in the downlink control signaling, wherein the HARQ ACK priority indication information is used for indicating whether to feed back HARQ ACK information of HARQ processes of all priorities; and feeding back the HARQ ACK information to the base station at least according to the HARQ ACK priority indication information. According to the technical scheme, the HARQ ACK information can be generated under the condition that HARQ ACKs with different priorities exist.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a HARQ ACK information feedback method and device, a storage medium, user equipment, and a base station. Background technique [0002] In the new radio technology (New Radio, NR), the type 3 hybrid automatic repeat request (Hybrid Automatic Repeat request, HARQ) acknowledgment (ACKnowledge, ACK) codebook (also known as one-shot HARQ ACK feedback), refers to UE After receiving the instruction to trigger the one-shot HARQ ACK, feed back the HARQ ACKs of all the HARQ processes (processes) of the configured cells to the base station at the same time. At the same time, if the current cell is configured as a code block group (Code Block Group, CBG), the HARQ ACK fed back is the HARQ ACK signaling of each CBG. If it is configured as New Data Indicator (NDI) reporting, the HARQ ACK and NDI of each HARQ process are reported together, and the HARQ ACK comes first, fol...
