Embodiment Construction

[0158] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0159] See figure 2 , which shows a flowchart of a method for determining a HARQ-ACK codebook provided by an embodiment of the present invention. Such as figure 2 As shown, the method is applied to a user terminal, and the method includes the following steps:

[0160] Step 201, acquire a first value set; wherein, the first value set is a subset of the second value set, and the second value set is a preset scheduling timing relationship (Scheduling timing, K0) from PDCCH to PDSCH The full set of values.

[0161] Step 202, determine the HARQ-ACK codebook according to the first value set.

[0162] Wherein, the second value set may be predefined or configured through high-layer signaling, and the second value set may be {0, 1, 2, 3, 4, 5, 8, 10, 16, 20...

Abstract

The embodiment of the invention provides a hybrid automatic repeat request acknowledgement HARQ-ACK codebook determination method, a user terminal and a base station. The method is applied to a user terminal and comprises the steps of obtaining a first value set, wherein the first value set is a subset of a second value set, and the second value set is a full set of preset scheduling timing relation values from a physical downlink control channel (PDCCH) to a physical downlink shared channel (PDSCH); determining HARQ-ACK codebook according to the first value set. Embodiments of the present invention can improve the transmission efficiency and performance of the HARQ-ACK codebook are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a hybrid automatic repeat request acknowledgment (Hybrid Automatic Repeat Request Acknowledgment, HARQ-ACK) codebook determination method, a user terminal and a base station. Background technique [0002] With the development and change of mobile communication service requirements, many organizations such as the International Telecommunication Union (International Telecommunication Union, ITU) have begun to study new wireless communication systems (ie, 5G NR, 5Generation New RAT). Among them, 5G NR supports flexible timing relationship. For the scheduling timing relationship of Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared CHannel), the Physical Downlink Control Channel (PDCCH, Physical Downlink Control CHannel) carrying its scheduling information indicates the PDCCH to PDSCH The scheduling timing relationship (ie, Scheduling timing), and the fe...
