Embodiment Construction

[0094] 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.

[0095]In the future, there may be situations where the number of CBGs of a TB in different CCs is not the same. In this case, the return codebook can be determined according to the product of the maximum number of CBGs contained in a single CC and the total number of times of data to be transmitted. The length of the CC, which contains the same number of CBGs, can also be combined to feed back a...

Abstract

The present disclosure relates to a HARQ feedback configuration 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. Wherein, the HARQ feedback configuration method includes: configuring HARQ codebook switching information for the data sending end according to the carrier aggregation information; and sending the HARQ codebook switching information to the data sending end. According to the carrier aggregation information, the embodiment of the present disclosure configures the HARQ codebook switching information for the data sending end to adapt to complex situations, and sends the HARQ codebook switching information to the data sending end, so that the data sending end can determine the data to be retransmitted accordingly Resource unit information for .

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 configuration 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 ...
