Abstract

The invention provides an uplink coverage enhancement method and device, communication equipment and a storage medium, and belongs to the technical field of wireless communication. The method comprises the following steps that user equipment receives a repetition indication message which is sent by a base station and is related to repeated transmission, and further sends an RV version corresponding to the repetition indication message to the base station through an uplink shared channel. Therefore, a dynamically changing RV version is set based on the repetition indication message sent by the base station, and the repetition indication message sent by the base station is determined based on decoding and decoding success conditions and channel quality, so that the accuracy of an RV repetition scheme is improved, and the enhanced coverage of the base station is improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to an uplink coverage enhancement method, device, communication device and storage medium. Background technique [0002] After simulation evaluation, it is found that channels in the Frequency range 1 (FR1) frequency band of the New Radio (NR) communication service, especially the Physical Uplink Shared Channel (PUSCH) of the uplink channel, need to be enhanced in coverage. The enhancement schemes discussed in the current standard are based on aspects such as time domain, frequency domain, demodulation reference signal (Demodulation Reference Signal, DMRS) and power domain. Among them, the redundancy version (RedundancyVersion, RV) repetition scheme is a candidate scheme based on the time domain, which is helpful for the receiver to perform frequency tracking and improve the accuracy of channel estimation. Of course, the RV repetition scheme may also be...
