Abstract

The invention discloses a transmission point identifying and RRM measuring method, equipment and system. A user terminal performs transmission point identification or RRM measurement respectively through a first DRS configuration parameter set and a second DRS configuration parameter set and reports identification results and measurement results to a base station. DRS configuration parameters contained in the second DRS configuration parameter set are those sent by the base station to the user terminal or selected by the user terminal from at least one DRS configuration parameter contained in the first DRS configuration parameter set. The number of parameters contained in the second DRS configuration parameter set is no larger than that of parameters contained in the first DRS configuration parameter set. Therefore, parameter configuration flexibility can be improved and the parameter measuring range and complexity can be further lowered on the basis of transmission point identification or RRM measurement respectively through the two parameter sets.

Description

Method, equipment and system that transfer point identification and RRM are measured

Technical field

The present invention relates to wireless communication technology field, particularly relate to method, equipment and system that a kind of transfer point identification and RRM (RadioResourceManagement, RRM) measure.

Background technology

In order to effectively improve the message capacity covering and increase system, industry proposes the application scenarios of Smallcell (small-cell or little base station), namely at covering blind spot or the covering focus of original MacroeNB (macrocell or macro base station), increase and dispose corresponding one or more Smallcell, to reach the object strengthening the network coverage and increase power system capacity.As shown in Figure 1, it is the schematic network structure being deployed with multiple small-cell (as A, B, C, D and E small-cell) in the overlay area of macro base station.

Particularly, because a large amount of website disposed by less, the usual needs of the coverage of Smallcell, therefore, if each Smallcell of (especially under the scene of dense deployment) is in opening under set scene always, then the energy consumption of network can greatly be increased.In addition, intensive small-cell is disposed also can bring more serious presence of intercell interference, reduces the communication performance of minizone.Therefore, in order to reach energy-conservation, the object such as interference management, some does not have the small-cell of service-user often can be set to resting state.

Particularly, at present, find to realize community fast and activate, in LTE (LongTermEvolution, Long Term Evolution) system, introduce DRS (DiscoveryReferenceSignal finds reference signal) this concept.UE (UserEquipment, user terminal) DRS can be utilized to carry out cell identification and RRM (RadioResourceManagement, RRM) measure, realize dynamic or semi-static activation with auxiliary network side to have the small-cell of service-user, close the small-cell not having service-user for a long time, to reach network energy-saving and to reduce the object of interference.

It should be noted that, at present, UE utilize DRS carry out cell identification and RRM measure time, the same group of DRS configuration parameter set normally issued according to macro base station carries out that the identification of community and RRM measure.Such as, as shown in Figure 2, in heterogeneous network scene, MacroeNB can send the DRS configuration parameter information of adjacent area to UE (as UE1 or UE2), UE is after receiving the DRS configuration parameter information issued from MacroeNB, cell identification and RRM measurement can be carried out according to the DRS configuration parameter information received, and after completing corresponding cell identification and RRM measurement, report corresponding cell identification result to MacroeNB and comprise RSRP (ReferenceSignalReceivingPower, Reference Signal Received Power) and/or RSRQ (ReferenceSignalReceivingQuality, Reference Signal Received Quality) etc. in interior RRM measurement result, the information such as the above-mentioned cell identification result reported according to UE to make MacroeNB and RRM measurement result activate corresponding one or more community for UE.

But, when adopting aforesaid way to carry out the measurement of cell identification and RRM parameter, due in the intensive cell scenario (as shown in Figure 1) of isomery, MacroeNB is in the starting stage and do not know which community of UE periphery is community to be found, therefore need all Smallcell (the small-cell A as shown in Figure 1 in MacroeNB overlay area, B, C, D and E) be all assumed to be the adjacent area of UE, and DRS configuration parameter information corresponding for all Smallcell (is comprised the Neighboring Cell List of current server community, find cycle reference signal and sub-frame offset etc.) all inform UE, correspondingly, UE needs to carry out corresponding cell identification and RRM to all Smallcell and measures, thus complexity needed for causing measuring is higher, power consumption is larger.In addition, if the result of carrying out cell identification and RRM measurement is all reported MacroeNB by UE, so also can exist and report the problems such as expense is larger.
