Problems solved by technology

However, the existing technology does not distinguish between different states of the user equipment when adjusting the OLLA value, so that the OLLA value corresponding to the MCS value of the user equipment in the information transmission process of different states cannot be effectively obtained, resulting in the corresponding MCS value obtained by the system. The OLLA value error is large, which affects the transmission performance of the system

Abstract

Examples of the present invention disclose an adaptive adjustment method and device for open -loop linking. First of allAn OLLA value of an adaptive adjustment value of the opening link; then the base station determines the current status of the user's device, and selects the current status of the current status of the user device from the corresponding OLLA values in each category, respectivelyThe corresponding OLLA value; finally, the base station is finally adjusted to the OLLA value of the OLLA value corresponding to the current status of the user device.The invention is suitable for the field of communication systems.

Description

technical field [0001] The invention relates to the field of communication systems, in particular to an open-loop link self-adaptive adjustment method and device. Background technique [0002] Link adaptive technology is a technology designed to overcome the time-varying characteristics of wireless channels and improve system performance. Its main advantage is that it can improve the reliability of communication links, improve power resources and frequency utilization, and improve system service quality and transmission capacity. [0003] In LTE (Long Term Evolution, long-term evolution) and subsequent evolution systems, AMC (Adaptive Modulation and Coding, adaptive modulation and coding) is a very important link adaptation method. However, the measurement error in the actual system environment makes it impossible for AMC to accurately track channel changes and obtain channel conditions, resulting in the selected modulation and coding scheme (usually represented by MCS (Mod...
