Problems solved by technology

[0004] In the future, it is possible that the number of CBGs of a TB in different CCs is not the same. For this situation, in related technologies, CCs with the same number of CBGs are combined to feed back a codebook (codebook) to reduce the number of feedback bits It is wasteful, but it needs to feed back multiple HARQ

Embodiment Construction

[0101] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0102] figure 1 It is a flow chart of a HARQ feedback method shown in an exemplary embodiment of the present application. This embodiment is described from the data receiving end, where the data receiving end can be a base station or a UE, such as figure 1 As shown, the HARQ feedback method includes:

[0103] In step S101, the component carrier CCs are grouped according to a binding rule, and ...

Abstract

The present disclosure relates to a HARQ feedback method and device, a method and device for determining data to be retransmitted, a data receiving device, a data transmitting device, and a computer readable storage medium. The HARQ feedback method includes: grouping a carrier unit CC according to a binding rule, wherein the binding rule includes the number of resource units included in a CC thatcan be bound into a group; calculating a parameter value in each CC group; generating a HARQ codebook with the same number as the CC groups, wherein the length of the HARQ codebook is determined by the parameter value in the corresponding CC group and the maximum resource unit number included in a single CC in the corresponding CC group; and feeding the HARQ codebook back to a data transmitting end. In the embodiment of the present disclosure, by grouping the carrier units CC according to the binding rule, calculating the parameter value in each CC group, and generating the HARQ codebook having the same number of CC groups, the amount of feedback information is optimized, and the amount of feedback information is reduced.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a Hybrid Automatic Repeat Request (HARQ) feedback method and device, a method and device for determining data to be retransmitted, a data receiving device, a data sending device, and a computer-readable storage medium. Background technique [0002] With the development of communication technology, the fifth generation of mobile communication technology (5th Generation, 5G for short) appears. The current business types of 5G include at least enhanced Mobile Broadband (eMBB for short), massive Machine Type Communication (mMTC for short), and Ultra Reliable Low Latency Communication (Ultra Reliable Low Latency Communication for short). URLLC) and many other types. These services are all data services, but they have different requirements for latency and reliability. For example, URLLC services are used in fields that require low latency, such as Internet of Ve...
