Below in conjunction with accompanying drawing, the present invention is described in further detail.
The invention provides a kind of CoMP status report scheme of enhancing, it can be used for dynamic/semi-static power division of Distributed C oMP and centralized CoMP on time domain/frequency domain.
For each base station (eNB), it receives the resource allocation information of other neighboring interfering base station, and based on affiliated CoMP framework, the CoMP state information corresponding to the wherein resource allocation information of each neighboring interfering base station is sent to corresponding resource allocation management equipment.Such as, under centralized CoMP framework, CN is the resource allocation management equipment of its controlled eNB, thus CN can be it controlled that eNB determines resource allocation information, or CN recommends resource allocation information to its controlled eNB and records the resource allocation information that each controlled eNB feeds back according to this recommendation.Under Distributed C oMP framework, each eNB is himself resource allocation management equipment, and also namely each eNB determines the resource allocation information of himself.
Further, under centralized CoMP framework, wherein the resource allocation information of each controlled eNB directly can be sent to each neighboring interfering base station of each controlled eNB by CN, also can be sent to each neighboring interfering base station of its correspondence by each controlled eNB from being about to its resource allocation information.Correspondingly, the CoMP state information of the corresponding corresponding controlled eNB of each neighboring interfering base station of each controlled eNB directly can be sent to CN, or is forwarded to CN via this corresponding controlled eNB.
Under Distributed C oMP framework, wherein each eNB is sent to each neighboring interfering base station of its correspondence from being about to its resource allocation information.Correspondingly, the CoMP state information of corresponding for correspondence eNB is directly returned to corresponding eNB by each neighboring interfering base station of each eNB.
Particularly, consult Fig. 1, in an exemplary centralized CoMP, eNB#1, eNB#2 and eNB#3 control by central coordinator device (CN, centralNode).The UE#1 of service is provided by eNB#1, is subject to the strong interference from eNB#2 and eNB#3.In order to eliminate such interference, CN adjusts the Resourse Distribute of eNB#1, eNB#2 and eNB#3, and the resource allocation information of these 3 base stations is all sent to eNB#1.According to the information of received resource allocation information and current UE #1, eNB#1 can determine the available resources of the descending scheduling to UE#1, and will the CoMP status information reporting of eNB#2 and eNB#3 be corresponded respectively to CN, wherein, CoMP state information can be enabled mode, i.e. the use information of available resources.According to the use information of these available resources, whether CN can monitor the ruuning situation of its controlled base station and determine its Resourse Distribute suitable, thus CN can make better decision for Resourse Distribute adjustment in the future.Therefore, the report of CoMP resource status provides the settlement mechanism of stable inter-cell interference cancellation.
Similarly, under Distributed C oMP framework, because each eNB can decide its resource allocation information in its sole discretion, thus each eNB can receive the CoMP state information of each interference base station this eNB relative from its neighboring interfering base station, therefore, each eNB can determine whether the Resourse Distribute of himself determines suitable, and is that Resourse Distribute in the future adjustment makes better decision.
