Abstract

The invention provides a CQI information receiving method, transmitting method, receiving device, and transmitting device. The CQI information receiving method includes sending high-level configuration signaling to a terminal; and receiving the CQI information from the terminal, wherein the CQI information is determined based on a CQI form which is obtained based on the high-level configuration signaling. According to the invention, the problem that the high data transmission reliability, low data transmission rate, and low system spectral efficiency cannot satisfy the coverage of the enhanced MTC terminal in the prior art is solved, and the effects of high data transmission reliability, low data transmission rate, and low system spectral efficiency required by the coverage of the enhanced MTC terminal can be achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a CQI information receiving method, sending method, receiving device and sending device. Background technique [0002] In the mobile communication system, due to the time-varying characteristics of the wireless fading channel, there are a lot of uncertainties in the communication process. In this way, when the signal-to-noise ratio of the wireless fading channel is relatively ideal, the system throughput has indeed been greatly improved. On the other hand, in order to ensure the reliability of communication, low-order modulation with low transmission rate and large redundant error correction are adopted. When the wireless channel is in deep fading, the communication is guaranteed to be reliable and stable. However, when the channel signal-to-noise ratio is high, due to the low transmission rate, the improvement of system throughput is restricted, resulting in waste of resources....
