Embodiment approach 1

[0064] Embodiment 1: The M DL SPS configurations correspond to one priority (such as high priority or low priority), and the M DL SPS configurations are determined according to the time domain resources indicated by the first HARQ-ACK feedback indication information. The SPS configures the corresponding HARQ-ACK codebook.

Embodiment approach 2

[0065] Embodiment 2: The M SPS configurations correspond to 2 priorities (such as high priority and low priority), and the M DL SPSs are determined according to the time domain resources indicated by the first HARQ-ACK feedback indication information Configure the corresponding HARQ-ACK codebook.

Embodiment approach 3

[0066] Embodiment 3: The M SPS configurations correspond to 2 priorities (such as high priority and low priority), and according to the time domain resources indicated by the first HARQ-ACK feedback indication information, determine the corresponding M1 DL SPS configurations HARQ-ACK codebook, the M1 DL SPS configurations correspond to high priority or low priority, M1≤M.

Abstract

The embodiment of the invention discloses a HARQ-ACK feedback method and equipment, which are used for solving the problem that a terminal cannot perform HARQ-ACK feedback under the condition that the terminal is configured with a DL SPS. The method can be applied to a terminal, and comprises the following steps: determining M HARQ-ACK codebooks corresponding to downlink semi-persistent scheduling DL SPS configurations according to first information; wherein the first information comprises at least one of the following information: first HARQ-ACK feedback indication information, first time division duplex (TDD) configuration information and first dynamic time slot format information; m > = 1, and M is an integer.

Description

technical field [0001] The present application belongs to the technical field of communications, and in particular relates to a hybrid automatic repeat reQuest-ACKnowledgement (HARQ-ACK) feedback method and device. Background technique [0002] For services that appear periodically and have a relatively fixed packet size, in order to reduce the overhead of downlink control signaling, the network side device can continuously allocate certain resources for the transmission of periodic services in a semi-persistent scheduling (Semi-Persistent Scheduling, SPS) manner . This downlink (DownLink, DL) SPS method can reduce the overhead of scheduling periodically sent long-term evolution voice bearer (Voice over Long-Term Evolution, VoLTE) voice packets (mainly reducing the physical downlink control channel (Physical Downlink Control Channel, PDCCH)), so that more resources are available for scheduling additional terminals. [0003] For the HARQ-ACK process that supports transport ...
