Problems solved by technology

[0005] Since the channel state of the UE changes with time, in order to perform accurate scheduling, the base station needs to obtain the latest channel state as much as possible, and the UE needs to report the channel state information frequently, which consumes a lot of precious air interface resources, resulting in a shortage of air interface resources. waste

Abstract

The present invention discloses a communication method, a user equipment (UE), a base station and a communication system. The method includes: the UE obtains channel state information; the UE determines whether the channel state meets a preset condition according to the obtained channel state information; When the channel state meets the preset condition, the UE reports indication information or the channel state information to the base station. It can be seen that after measuring and obtaining the channel state information, the UE determines whether the current channel state meets the preset conditions according to the channel state information, and reports to the base station only when the preset conditions are met, thereby reducing unnecessary reporting and effectively saving air interface resources.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a communication method, user equipment, base station, and communication system. Background technique [0002] In the communication system, the use of radio resources is controlled by the base station on the network side, that is, the base station decides how the user equipment (UE) uses the air interface resources, such as the radio resource block (resource block, RB) and the modulation and coding method (modulation and coding) used. scheme, MCS), etc. In order to effectively use the air interface resources, the base station will perform downlink scheduling according to the actual air interface quality of the UE. For example, when the air interface quality is good, a higher-level MCS (which can transmit more data) is used; when the air interface quality is poor, a lower MCS is used. Level MCS to make full use of air interface resources. In order to achie...
