Method, equipment and system for reporting signal channel state

Abstract

Disclosed are a method, apparatus and system for reporting channel status. The method comprises: a UE receiving the feedback cycle information sent by a first base station, the feedback cycle information instructing the UE to report the cycle N of the channel status of a first type subframe; the UE measuring the channel status of the first type subframe; and the UE reporting the measured channel status to the first base station according to the cycle N. Wherein the first type subframe is a subframe in the first base station that is temporally the same as a second specific subframe, the second specific subframe is a subframe that only sends a portion of all the channels, the subframe position of the second specific subframe is configured by a second base station, and the second base station is an interference base station of the first base station. The method realizes the effective scheduling of UE for the first base station.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method, device and system for reporting channel state. Background technique [0002] The heterogeneous network refers to a heterogeneous system in which low power nodes (Low power nodes, LPNs) are deployed in the coverage area of ​​the macro base station to form different node types with the same coverage. There may be mutual interference among the nodes in the heterogeneous network. For example, the transmit power of the macro base station is relatively large, so the downlink signal of the macro base station may interfere with the reception of the downlink signal of the LPN by users at the edge of the coverage of the LPN, and the high-power terminals at the edge of the coverage of the macro base station may also interfere A nearby LPN is causing interference. As another example, in a CSG (Closed Subscriber Group) scenario, the home base station may also interfere with nea...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that other interfered nodes received different interferences at the subframe positions corresponding to the ABS subframes of the interfering base station and non-ABS ordinary subframes, and the quality of the downlink channel was also different, but at present There is no existing technology that other nodes can use the ABS configuration mechanism of the interfering base station to effectively schedule the interfered user equipment (User Equipment, UE)
