Embodiment Construction

[0042] Those skilled in the art understand that, as mentioned in the background, the existing technical solutions for performing HARQ feedback based on PUCCH resource sets have defects.

[0043] The inventors of the present application have found through careful study that the PUCCH resource set information indicated by the PUCCH-Resource-Common indication index in System Information Block 1 (ie SIB1) includes: PUCCH format (PUCCH format), start of PUCCH transmission start symbol (First symbol), duration (duration) and physical resource block index (or called offset value). Wherein, the duration of the PUCCH resource may be 2 symbols, 4 symbols, 8 symbols, 14 symbols and so on. In the NR system, a time slot usually includes 14 OFDM symbols, which are referred to as symbols in this article.

[0044] In the prior art, the symbol length occupied by the PUCCH resources configured in SIB1 for HARQ feedback is fixed and has only one value. Once SIB1 indicates the PUCCH resource se...

Abstract

A HARQ feedback information transmission, indication method and device, storage medium, terminal, and base station, the HARQ feedback information transmission method includes: receiving HARQ configuration information sent by a serving cell, the HARQ configuration information includes indication information, the The indication information is used to indicate at least two sets of PUCCH resources, and the PUCCH resources in the at least two sets of PUCCH resources have different durations; the PUCCH resources are selected for HARQ feedback according to the received signal quality of the serving cell. Through the technical solution provided by the invention, the HARQ feedback performance of UEs in different serving cell locations can be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for transmission and indication of HARQ feedback information, a storage medium, a terminal, and a base station. Background technique [0002] In 5G new radio (New Radio, NR for short, also called new air interface) technology, the base station schedules user equipment (User Equipment, UE for short) through downlink control information (Downlink Control Information, DCI for short). The DCI may indicate a downlink assignment (Downlink Assignment, DL Assignment for short) or an uplink grant (Uplink Grant, UL Grant for short). Wherein, the downlink assignment is used to indicate to the UE the data transmitted on the physical downlink shared channel (Physical Downlink Shared channel, PDSCH for short). At this time, the DCI can indicate the modulation and coding format of the data transmission, the time-frequency resource of the PDSCH (for ex...
