Abstract

The present invention discloses a CSI (channel state information) receiving method and an access network device. The invention aims to solve the technical problem of incapability of realizing timely scheduling which is caused by long transmission time required by CSI under a D-RAN (Distributed Radio Access Network) framework. The method includes the following steps that: a first access network device receives a notification message sent by a second access network device, wherein the notification message is used for indicating condition information based on which a terminal device residing in the first cell of the second access network device sends CSI; and the first access network device receives the CSI sent by the terminal device on resources which are determined according to the condition information indicated by the notification message.

Description

technical field [0001] The present invention relates to the communication field, in particular to a CSI receiving method and access network equipment. Background technique [0002] In order to improve frequency utilization efficiency of a Long Term Evolution (Long Term Evolution, LTE) system, adjacent cells usually use the same frequency band when deploying an LTE network. However, under this deployment scheme, severe inter-cell interference makes the throughput of edge users drop sharply. In this case, a coordinated multipoint transmission (Coordinated Multipoint Transmission, CoMP) technology is considered to be an effective method to solve the inter-cell interference problem and improve the throughput of edge users. In the CoMP technology, multiple adjacent cells can jointly process or coordinate edge users to avoid interference and improve edge user throughput. [0003] In the frequency division duplex (Frequency Division Duplex, FDD) system, the user equipment (User E...
