The embodiment of the invention provides a measurement, selection and reporting method of channel quality information. The method comprises the following steps: terminal equipment receives K referencesignals sent by network equipment, wherein K is not less than 1; the terminal equipment performs channel quality measurement on K reference signals to acquire a channel quality measurement result; the terminal equipment receives first information configured by the network equipment, and the first information is the selection type of the channel quality information; the terminal equipment selectsP channel quality information from the channel quality measurement result according to the first information, wherein P is not less than 1; and the terminal equipment sends P channel quality information to the network equipment. In the technical scheme provided by the embodiment of the invention, the network equipment configures the selection type of the channel quality information for the terminal equipment, namely, configuring the feature information of selecting the channel quality information for the terminal equipment; the terminal equipment selects the channel quality information satisfying the feature information in the channel quality measurement result, thereby realizing the corresponding communication demand.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for measuring, selecting and reporting channel quality information. Background technique [0002] In a wireless communication system, in order to improve transmission efficiency under the premise of ensuring transmission reliability, network devices usually estimate the quality of the wireless channel used to transmit signals, and determine a scheduling scheme according to the quality of the wireless channel. In the current wireless communication system, the quality information of the wireless channel is usually obtained by means of a transmission reference signal. Communication systems usually use different types of reference signals: one type of reference signal is used for channel quality measurement, such as cell-specific reference signal (CRS), so that channel quality measurement and cell selection and handover can be realized; another type The re...
