Abstract

The embodiment of the invention provides a configuration method of a channel quality indicator (CQI) reporting period, a terminal and network side equipment. The method comprises the following steps:acquiring a first CQI reporting period in a first signaling; detecting whether a second CQI reporting period exists in the second signaling or not; if the second CQI reporting period is detected in the second signaling, configuring a reporting period of the CQI according to the second CQI reporting period; if the second CQI reporting period is not detected in the second signaling, configuring a reporting period of the CQI according to the first CQI reporting period. Thus, according to the invention, the reporting period of the CQI can be rapidly adjusted through the second signaling, the defect that the CQI reporting period is configured only based on the RRC signaling is overcome, and the problem that in the prior art, the CQI reporting period is adjusted through the RRC signaling so thatconsequently expenditure is too large due to the fact that the RRC signaling needs to be frequently sent under some scenes is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a configuration method, a terminal and a network side device of a channel quality indicator (Channel Quality I-indicator, CQI) reporting period. Background technique [0002] Adaptive Modulation and Coding (AMC) technology can improve the spectrum efficiency and throughput of the system by dynamically selecting the Modulation and Coding Scheme (MCS) that matches the channel conditions. In the existing technical solution, the base station sends a reference signal to the terminal, the terminal estimates the channel condition, and feeds it back to the base station in the form of CQI, and the base station selects the MCS according to the CQI fed back by the terminal. Currently, there are two configurations for reporting the CQI: periodic and aperiodic. Wherein, specific periodic parameters in the periodic reporting manner are configured by radio resource control (...
