Description
Technical field
The present invention relates to moving communicating field, particularly relate to the out-hole run method and system in a kind of junction network.
Background technology
Relaying technique is as a kind of emerging technology, cause and note more and more widely, be regarded as super 3 g mobile communication system (B3G, Beyond the Third Generation in mobile communicationsystem) or the key technology of forth generation mobile communication system (4G, The Fourth Generation in mobilecommunication system).Because future wireless system or cellular system require to increase coverage, to support the transmission of higher rate, this proposes new challenge to wireless communication technology.Meanwhile, the cost issues of system building and maintenance is more outstanding.Along with the increase of transmission rate and communication distance, the energy consumption issues of battery also becomes outstanding, and the radio communication in future will adopt higher frequency, and the pathloss attenuation caused thus is more serious.By relaying technique, traditional one hop link can be divided into multiple multi-hop link, due to Distance Shortened, this greatly will reduce path loss, contribute to improving transmission quality, expand communication range, thus provide quicker better service for subscriber equipment (UE).
As shown in Figure 1, comprise at junction network: relay station, base station, UE and the link between them.Wherein, the link that relay station participates between the UE of service and relay station is called as access link; Link between relay station and base station is called as back haul link; The link that base station participates between the UE of service and base station is called as the link that direct transfers.
As shown in Figure 2, when UE is positioned at base station and the region of covering combined by relay station, can adopt the mode of collaboration communication, that is: base station and relay station are the mode of UE service jointly, can improve power system capacity and the level of resources utilization like this.
Because self-interference causes the reception of relay station and launch to carry out in identical frequency band simultaneously, and be subject to the restriction of disposal ability and coverage, certain relay station is difficult to also not need all to serve UE all in community.In order to more reasonably utilize relay station resource, first can select a part by network side from the UE community needs the UE of relay station subsidiary communications to accept the service of relay station, multiple relay station may be there is in a community simultaneously, because present position is different, each relay station is also different to the service effectiveness of certain UE, therefore not only need first to select a part of UE to accept relay station service, then certain UE selected is also needed specifically to be served by which or which relay station, that is, also need for UE select its communication lines by, and divide the Radio Resource being used in communication for UE, as shown in Figure 3, Fig. 3 comprises three UE, three relay stations and a base station, when collaboration communication, base station, each relay station, and comprise between each UE many communication lines by.
In prior art, because the relay station for collaboration communication in community does not have independently community ID, therefore independently public guide frequency (CRS is not had yet, Cell-specific reference signal), such UE just cannot differentiate different nodes by CRS, and continue to use the down-run survey method of Long Term Evolution (LTE, Long Term Evolution) or coordinated multipoint transmission (CoMP, cooperative multi-site processing).Wherein, node refers to base station or relay station.At present, for distinguishing each node and providing the good and bad Resources allocation of service quality according to each node, the existing solution adopted is: the transmitting carrying out CRS between each node in the mode of time-division, to complete down-run survey.Like this, the UE of connection status feeds back for the measurement of the CRS of certain subframe the differentiation information just containing node, base station is after receiving UE measurement feedback, subframe position corresponding to it, just can judge the quality of different node to certain UE service effectiveness, thus be that UE distributes route and Radio Resource by base station.
The weak point that this existing solution exists is: the existing CRS for down-run survey of CRS of transmitting, there is again the CRS for routine data demodulation, in LTE system, UE due to legacy version needs the demodulation carrying out data according to descending CRS, if relay station also sends CRS, then the CRS being used for demodulation and the CRS being used for measuring cannot separate by UE, the hydraulic performance decline of data demodulates may be caused, also can have influence on the accuracy of measurement simultaneously, thus weaken scheduling gains, reduce systematic function, therefore, at present in the urgent need to a kind of new measurement scheme, above weak point can be solved.
Summary of the invention
In view of this, main purpose of the present invention is to provide the method and system of the out-hole run in a kind of junction network, can not have influence on normal data demodulation and the reception of downlink data, the UE of compatible legacy version; Improve the accuracy measured, to reduce signaling consumption, ensure scheduling gains, thus improve the efficiency of junction network transmission.
