example 1

[0076] Example 1: adding identification domain information to the DCI, the identification domain information is used to distinguish the DCI from other DCIs;

example 2

[0077] Example 2: Change the field I MCS The value of is set to a predetermined value to distinguish, for example, I MCS = 30;

example 3

[0078] Example 3: Change the field I MCS and the value of PRB is set to a predetermined value to distinguish, for example, I MCS =29 and 4

[0079] In the present invention, the example of RRC signaling design is as follows:

Abstract

The embodiment of the invention discloses a method for transmitting periodical feedback information. The method comprises the following steps: a base station transmits periodical feedback long-term information through a wireless resource control (RRC) signaling, including feedback types, feedback periods and the like, and releases the periodical feedback resource through the RRC signaling; physical resource information of the periodical feedback is transmitted through a physical downlink control channel (PDCCH), including the number, positions and modulated code modes and the like of physical resource blocks (PRB); and a terminal transmits the periodical feedback information according to the periodical feedback resource distributed by the base station. The embodiment of the invention also discloses a system and equipment for transmitting the periodical feedback information. By adopting the invention, reasonable dispatch and transmission of the periodical feedback information in a long term evolution (LTE)-A system can be realized.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, system and equipment for transmitting periodic feedback information. Background technique [0002] In the Long Term Evolution (LTE-A) system, the Coordinated multi-point (CoMP) transmission and reception (transmission / reception) technology can be used to increase the coverage of high data rates, improve the throughput of the cell edge and / or increase System throughput. The so-called coordinated multi-point means that multiple geographically separated transmission points cooperate to participate in the transmission / reception of data for a UE, and the multiple transmission points are different cells belonging to one or more base stations. [0003] CoMP technology is divided into downlink CoMP and uplink CoMP. Downlink CoMP means that the terminal (UE) needs to measure or process downlink signals or data of multiple cells; uplink CoMP means that multiple cell...
