Resource state report message configuration method

Abstract

A method configuring resource state report message in a first base station in a wireless communication system comprises the following steps: the first base station sends a first message to an adjacent second base station, wherein the first message comprises information used for indicating the second base station to carry out approximation blank subframe state report using a first parameter as a period; the first base station receives the approximation blank subframe state report using the first parameter as a period by the second base station.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to the technical field of wireless communication. Background technique [0002] In the field of wireless communication, the problem of inter-cell interference has always been a hot research direction in recent years. Especially with the increasingly widespread application of heterogeneous network structures, how to solve the inter-cell interference caused by high-power macro cells to low-power micro cells has become an urgent practical problem to be solved. The industry has also proposed many targeted solutions. Among them, the Inter-Cell Interference Coordination (ICIC for short) technology is considered to have a good application prospect. The ICIC technology performs cooperative transmission of multiple base stations through signaling interaction between adjacent base stations, thereby reducing the impact of inter-cell interference. In the 3GPP specification, an ...

However, this means that the feedback of the ABS state must be performed at a higher frequency to enable fast reconfiguration

Obviously, the existing standardized resource status reporting cycle cannot meet such requirements: First, only under the premise that only the ABS status needs to be sent quickly, the existing resource status reporting cycle mechanism will inevitably shorten the sending cycle of all information, thereby greatly increasing The signaling overhead on the X2 interface is reduced, and the performance of the entire system is reduced; in addition, under the existing specification, the report can only be performed once every 1000 milliseconds at the fastest, and the high time-varying ABS feedback requirement may be as high as milliseconds. Some specifications cannot meet this requirement

[0005] Therefore, the object of the present invention is to find a novel method applicable to highly time-varying ABS state feedback; this method needs to be able to configure the ABS state sending cycle that reaches the millisecond level the fastest, so as to perform fast periodic feedback; It should not affect the sending cycle of other parameters and avoid waste of signaling overhead; at the same time, it should be compatible with existing specifications as much as possible to avoid excessive changes to existing protocols
