Abstract

The invention relates to a link adaptive adjustment method, device and system and a storage medium. The link adaptive adjustment method comprises the following steps: receiving a configuration message transmitted by a base station, wherein the configuration message is a channel state information (CSI) report configuration containing a channel quality indication (CQI) reporting format and a link parameter, the reporting format of the channel quality indicator (CQI) is subband reporting, and the link parameters comprise a CQI bit width format and a target BLER value; completing the subband CQI measurement based on the configuration message, and reporting a CSI measurement report to the base station, wherein the CSI measurement report is used for indicating the base station to obtain an inner loop link adaptive modulation and coding strategy (MCS) value; obtaining an MCS increment delta-MCS based on the configuration message, and reporting HARQ-ACK information to the base station, wherein the HARQ-ACK information is used for indicating the base station to acquire an outer loop link adaptive modulation and coding strategy (MCS) value. According to the invention, the configuration and application flexibility is provided for different high-reliability application scenarios.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a link adaptive adjustment method, device, system and storage medium. Background technique [0002] Wireless communication systems have been widely deployed for daily voice, video, data and short message services. Mobile communication has gone through several stages of development: 2G (GSM, Global System for Mobile Communications), 3G (TD-SCDMA, UMTS) and 4G (LTE, Long Term Evolution), and has now entered the R&D and deployment stage of 5G (NR). [0003] The 3GPP NR (New Radio) protocol supports three types of services: eMBB (Enhanced Mobile Broadband, enhanced mobile broadband), URLLC (Ultra-reliable and Low Latency Communications, high reliability and low latency communication) and eMTC (Massive Machine Type Communication, large-scale Machine Type Communication). The R15 protocol frozen in June 2018 supports eMBB services, and the R16 protocol fro...
