Embodiment Construction

[0030] The basic idea of ​​the present invention is: the base station sets the initial value of the feedback threshold for the coordinated multi-point (CoMP) terminal and the non-CoMP terminal respectively, and sends it to each terminal; the base station classifies the terminal into a high-priority user and a low-priority user, And send instruction information to the terminal; within the preset adjustment period, the terminal performs information feedback according to the initial value of the priority and the feedback threshold; after the adjustment period arrives, the base station adaptively adjusts the feedback threshold according to the feedback rate of the terminal and the SINR curve , and send it to each terminal for further information feedback.

[0031] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

Abstract

The invention discloses a self-adaptation feedback method. A base station sets initial values of a feedback threshold respectively for a coordinated multi-point (CoMP) terminal and a non-CoMP terminal and sends the initial values of the feedback threshold to all terminals. The station classifies the terminals into a high priority user and a low priority user and sends indication information to the terminals. In a preset adjustment period, the terminals feed information back according to the initial values of priority and the feedback threshold. After the adjustment period is due, the station adjusts the feedback threshold in a self-adaptation mode according to a response rate of the terminals and a signal to interference plus noise power ration curve and sends the feedback threshold to all terminals to continuously carry out information feedback. The invention further discloses a system. By means of the self-adaptation feedback method and the system, feedback information quantity of user terminals can be reduced under a premise that quality of service (QoS) demands of the terminals, fairness among the terminals and system frequency spectrum efficiency are achieved.

Description

technical field [0001] The invention relates to terminal feedback information technology in coordinated multi-point technology, in particular to an adaptive feedback method and system based on threshold judgment. Background technique [0002] The Long Term Evolution-Advanced (LTE-A) is a third generation partnership project (Third Generation Partnership Project, 3GPP) in order to meet the requirements of the advanced International Mobile Telecommunications (International Mobile Telecommunication-Advanced, IMT-Advanced) Technology evolution based on Long Term Evolution (LTE) is required. In view of the severe inter-cell interference in the LTE system, and the existing interference coordination technology cannot well solve the problem of low spectral efficiency of edge users, the Coordinated Multi-Point (CoMP) technology is introduced in LTE-Advanced. [0003] CoMP technology is considered to be an effective means to enhance and improve the performance of cell edge users. Ac...
