Macro base station with oneself cover little base station down and be connected through optical fiber, it is mutual to guarantee that big capacity hangs down the signaling data of time delay; Can not ignore being connected of time delay through the limited capacity of similar X2 interface between first collaboration region and second collaboration region.Under this network design, UE is equally distributed, that is to say, some UE is positioned at the center area of coverage of macro base station; Some UE is positioned at the center area of coverage of certain little base station; Some is positioned at the macro base station of same collaboration region and the overlapping area of coverage of little base station; Some is positioned at the covering edge of collaboration region.
It mainly is in the process that moves, can fast monitored arrive corresponding coordinated regions for UE that RRM measures collection; When UE is positioned at coordinated regions, can measure collection simultaneously and carry out possible channel measurement through reasonable configuration RRM; With assess various possible CoMP transmission plans the performance gain of the integral body that can bring, thereby select to carry out user's scheduling for the optimum scheme of whole system.
The management of mentioned RRM measurement collection is accomplished by the base station among the present invention, measures collection by the base station that UE inserted to UE configuration RRM.For the UE of initial access network, the base station can be according to the distribution of UE, is that the corresponding RRM of this UE measures the element of concentrating with the information configuration of the node identification of all nodes in the present residing CoMP of the UE zone; Moreover; Also can be according to the position in this CoMP zone; Through the information of search or the node identification through searching all nodes that routing table obtains all adjacent C oMP zones, then equally the information configuration of the node identification of all nodes in these adjacent C oMP zone is measured to the corresponding RRM of this UE and concentrated; That is to say that the RRM of certain UE measures to concentrate and comprises: the information of the node identification of all nodes in the UE present located CoMP zone in the node identification of all nodes and all adjacent C oMP zone.Wherein, so-called adjacent referring to geographically bordered on.Wherein, to measure the configuration of collection be that the base station is passed through high-level signaling and disposed to UE for said RRM.Because whether measure a large amount of nodes through UE exists; Need to consume a large amount of power resources; And may cause bigger time delay, and the deployment of network side all is known for all base stations generally speaking, even variation has taken place in some base station or node; But stable existence always on long terms, and this variation can accomplish the renewal of information through interactive information between the base station.Measure the expense that collection can be saved channel resource through the base station to UE configuration RRM, more effectively utilize channel resource.
When UE moved between different coordinated regions, the RRM of this UE measures collection need carry out the position renewal.As when UE just when first collaboration region moves to second collaboration region,
At first will connect through the Data Control that mutual contextual information etc. is kept subframe, when can be after new coordinated regions are according to new transmission plan and base station interactive information, the RRM that the base station will be new measures collection and disposes to UE; Wherein, said new RRM measures to collect and comprises: all nodes of second coordinated regions that UE was positioned at, the information of the node identification of all nodes in the 4th collaboration region adjacent with second collaboration region, first collaboration region; Promptly increased satisfactory the 4th collaboration region; Information deletion with the node identification of original undesirable the 3rd collaboration region; In specific embodiment of the present invention, the attended operation that said RRM measures collection is as the integral body of upgrading with all node identifications in the collaboration region.Like this; No matter which coordinated regions UE is positioned at; Can obtain self to keep corresponding transmission plan and between different coordinated regions, switch needed RRM and measure collection information; These information has been arranged, the monitoring of carrying out link-quality of target can have been arranged when switching or preparing to switch, be compared to all possible nodes of exhaustive measurement and improved efficient.
When moving in the coverage of UE different nodes in single coordinated regions; RRM measures collection and need not upgrade; Only need measure collection or report set or transmission collection to other physical layer according to the position of UE waits to adjust accordingly and gets final product; Like this, can guarantee that RRM measures the configuration of collection and increases operation such as deletion can not take too much signal resource.Wherein, said position according to UE is measured collection to physical layer and is specially, and measures at said RRM on the basis of collection, obtains the node of signal transmission power in specified scope, carries out channel measurement operation to said node.In sketch map as shown in Figure 3; UE_1 for first coordinated regions; The node that its physical layer measurement collection comprises possibly be the 1st macro base station and the 1st little base station; And if this UE moves to the residing position of UE_3, the element that its physical layer is measured collection will be adjusted into the 1st macro base station and the 2nd little base station accordingly.
Wherein, it is that the base station is directed against each UE and safeguards that RRM measures collection, disposes to UE through high-level signaling.
The present invention also provides a kind of base station, and this base station has solved when UE moves between the node of different shared same cell IDs under CoMP, and UE can't locate, and is not sure of suitable R RM and measures the plain problem of element of set.
The invention discloses a kind of base station, said base station has unique node identification.Fig. 4 is the structural representation of a kind of base station among the present invention, and is as shown in Figure 4, wherein,
