Abstract

The embodiment of the invention provides a codebook sending method, a codebook receiving method, a terminal and network equipment. The sending method comprises the following steps: sending a HARQ-ACK codebook to the network equipment, wherein the HARQ-ACK codebook comprises first feedback bit information of a first HARQ process and first NDI information located after the first feedback bit information, the first HARQ process corresponds to at least two TBs, the first feedback bit information is obtained by executing a first preset operation on HARQ-ACK bit information of at least two TBs, and the first NDI information is determined according to NDI information of at least one of at least two TBs. According to the embodiment of the invention, correct construction and transmission of the HARQ-ACK codebook can be ensured under the condition that NDI information of at least two TBs exists, so that normal HARQ-ACK feedback and data transmission are ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a codebook sending method, receiving method, terminal and network equipment. Background technique [0002] In the prior art, for a one-shot Hybrid Automatic Repeat reQuest-ACK (HARQ-ACK) codebook, if a maximum of two downlink codewords are configured to receive and report new data of codewords Indicate (New Data Indicator, NDI) information, and enable spatial bundling (Spatial Bundling), the NDI information of each codeword needs to be included in the one-shotHARQ-ACK codebook. However, in the case of the NDI information of two codewords, it is not clear how to incorporate it into the corresponding HARQ-ACK codebook. Contents of the invention [0003] Embodiments of the present invention provide a codebook sending method, receiving method, terminal, and network equipment, so as to solve the problem of how to include the NDI information of two codewords in the co...
