In the LTE system, for obtaining the quality of wireless channel of forward link (down link), for frequency division multiplexing (Frequency Division Duplexing, FDD) system, be designed with CRS on descending carrier, and for time division multiplexing (Time Division Duplexing, FDD) system, be designed with CRS on the corresponding descending sub frame of carrier wave, UE measures CRS and gives eNB measurement feedback.UE measures CRS and comprises two kinds of forms, and a kind of is long period assessment and the measurement that needs layer 3 (Layer3, L3) participation filtering, and the present invention is referred to as L3 and measures; Another kind is short period (measuring with respect to L3) assessment and the measurement that does not need L3 participation filtering, and the present invention is referred to as layer 1 (Layerl, L1) and measures.
The quality of wireless channel that wherein the L3 measurement obtains can assist eNB to carry out the RRMs such as CMC, ICIC.As Fig. 1 is that L3 measures transaction module, comprise L1 measurement function module 100 and L3 filtering and report evaluation function module 101.L1 measurement function module 100 comprises two sub-function module, and sub-function module 100-1 (L1 sampling) receives signal CRS to A and sampled (or claiming to measure), and sub-function module 100-2 (L1 filtering) carries out filtering to the sampled result of 100-1.L3 filtering and report evaluation function module 101 comprise two sub-function module, the filtering result that sub-function module 101-1 (L3 filtering) periodically passes to L3 to L1 is carried out filtering, and sub-function module 101-2 (L3 reports assessment) judges whether L3 filtering result triggers measurement report.If the triggering measurement report, L3 sends to eNB (B sends measurement report) by measurement report.
Wherein, the channel quality that the L1 measurement obtains can assist eNB to carry out scheduling of resource.L1 is measured filtering to the CRS signal, and reports to eNB after according to the mode with the eNB agreement, result being mapped to channel quality indication (Channel Quality Indicator, CQI).
In order to meet the performance index of LTE-A, especially reach the performance requirement of LTE-A to Cell Edge User, the CoMP transmission technology is suggested.The CoMP transmission technology is counted as the raising community marginal user performance, effectively suppresses one of important technology of presence of intercell interference.The LTE-A system can increase by the CoMP technology covering of high data rate, thereby improves the throughput of cell edge, further improves throughput of system.So-called CoMP refers to a plurality of eNB that separate on geographical position, or claims the transfer of data of a plurality of transmission nodes (Transmission Point, TP) participation and same UE.Be illustrated in figure 2 a kind of CoMP deployment scenario schematic diagram.3 communities adjacent one another are in Fig. 2, Remote Radio Unit 201 (the Remote Radio Head of the 200, community, base station 2 of community 1, RRH), the Remote Radio Unit 202 of community 3 is shared channel information, the distributed intelligence of UE 203, and carry out combined dispatching based on these information, jointly determine scheduling and/or the beam shaping of UE.Wherein between base station 200 and Remote Radio Unit 201 and 202, with optical fiber, be connected.
In order to meet the LTE-A high-throughput, the requirement of high transfer rate, especially reach LTE-A to strengthening the demand of focus covering, cell edge, indoor covering etc., on traditional isomorphism cellular network basis, is introduced into some low power nodes.As Fig. 3 is a kind of heterogeneous network deployment scenario.Base station 300 forms macrocell 1, is deployed with two low power nodes LPN301 and LPN302 in the coverage of macrocell 1 and covers in order to strengthen focus, the signal cover that overlay area 2 is LPN 301, the coverage that overlay area 3 is LPN 302.Between base station 300 and LPN 301, LPN 302, with optical fiber, connect.
For further improving the systematic function of heterogeneous network, the CoMP transmission technology can be combined with heterogeneous network, such as in Fig. 3, UE 303 is positioned at the coverage of macrocell 1 and LPN 301 simultaneously, and base station 300 and LPN 301 can participate in the transmission of UE 303 jointly.In like manner, UE 304 is positioned at the coverage of macrocell 2 and LPN 302 simultaneously, and base station 300 and LPN 302 can participate in the transmission of UE 304 jointly.
In heterogeneous network as Fig. 3, can be by the overlay area of LPN 301 2 when operator disposes, the overlay area 3 of LPN302 is designed to respectively independently community, be designed with respectively independently synchronizing channel, Physical Cell Identifier (Physical Cell Identity, PCI), CRSDeng De community, now overlay area 2 can be designated as community 2, and overlay area 3 can be designated as community 3.Operator can not be designed to independently community by the overlay area 3 of the overlay area of LPN 301 2, LPN 302 while disposing yet, such as not being overlay area 2 and/or overlay area 3 independent design synchronizing channels, PCI, CRS etc., or it is identical with macrocell 1 that synchronizing channel, PCI, the CRS of overlay area 2 and/or overlay area 3 is set.
If no special instructions, above base station, LPN, be referred to as node (Point) in the description follow-up in the present invention such as RRH.
The CoMP Technology Need selects suitable transmission node jointly to participate in transmission, and for selecting suitable transmission node, the CoMP technology has proposed the concept of several resource collections.As shown in Figure 4, the zone that 400 black dotted lines are surrounded is CoMP resource management set (CoMP Resource Management Set), UE carries out L3 to the resource in CoMP resource management set and measures and give network terminal (such as base station) measurement feedback, network terminal can utilize the measurement result of described feedback to select CoMP measuring assembly, the zone of having selected as shown in Figure 4 401 solid black lines to surround.UE carries out L1 to the resource in the CoMP measuring assembly and measures and give network terminal measurement report, and network terminal can utilize the measurement result of described feedback to select CoMP cooperation set, has selected as shown in Figure 4 402 shadow region.Node in CoMP cooperation set 402 participates in determining scheduling and/or the beam shaping of UE405 jointly, and actual participation and UE405 transmission can be only the part of nodes in CoMP cooperation set, such as node 403 and node 404.
It should be noted that, as mentioned before, operator can be deployed as the overlay area of LPN independently community while disposing LPN also can not be deployed as individual cell.Can predict, the zone that also can as required base station be covered when operator disposes base station in the future is deployed as independently community or is not deployed as individual cell.If the zone that some node covers is deployed as independently community, UE can measure CRS and CRS is fed back to network terminal, network terminal can utilize the measurement result of described CRS to select the CoMP measuring assembly, and UE also can measure CRS when the individual cell in the CoMP set is measured.Otherwise, if the zone that some node covers is not deployed as independently community, need to introduce the specific reference signal of UE, as channel state information reference signals (Channel-State Information reference Signal is called for short CSI-RS).The CSI-RS resource of the node that the network terminal configuration need to be measured is in CoMP resource management set, UE carries out the L3 measurement and gives network terminal measurement feedback CSI-RS, and the CSI-RS resource that network terminal is selected node and configured corresponding node is in the CoMP measuring assembly.
L3 based on CSI-RS measures, can be for the configuration management of CoMP measuring assembly in the CoMP technology, and along with the continuous evolution of cordless communication network, the L3 based on CSI-RS measures also can be for CMC, ICIC etc.Below elaborate the L3 measuring management method based on CSI-RS.
Method one,
The measurement of configuration based on CRS and the measurement based on CSI-RS, in same measuring object, are determined measuring reference signals by measuring configuration relation, and UE carries out measurement.
Wherein configure in the measurement and the measurement based on CSI-RS and same measuring object based on CRS, refer to for a specific frequency, configure a measuring object, in this measuring object, configuration needs the CSI-RS resource of measuring simultaneously.
In the LTE system, the UE configuration L3 that eNB can control for Radio Resource (Radio Resource Control, RRC) connection status measures, to meet the RRM demands such as CMC, ICIC.In the LTE system, to be measured as example, concrete, eNB is that the UE configuration comprises following measurement parameter:
1, measuring object (Measurement Object, MO) configuration: eNB can configure a plurality of MO for UE, the frequency that each MO is a LTE;
2, report configuration (Reporting Configuration, RC) configuration: eNB can configure a plurality of RC for UE, the criterion that in each RC, configuration report triggers (such as, periodic triggers, Event triggered etc.), report triggering amount (Reference Signal Received Power (Reference Signal Received Power, RSRP), perhaps Reference Signal Received Quality (Reference Signal Received Quality, RSRQ)) and other parameters.
3, measure sign (Measurement Identity, MID) configuration: eNB can configure a plurality of MID for UE.
LTE L3 measuring management model as shown in Figure 5, the associated MO of each MID and a RC, as measured sign 505 correlation measurement object configurations 501 and report configuration 503 in Fig. 5.By configuring a plurality of MID, MO can associated a plurality of RC, as measuring object configuration 502 in Fig. 5 identify 506 and measure sign 507 associated two different RC respectively by measurements, report that configuring 503 configures 504 with reporting.Equally, by configuring a plurality of MID, RC can associated a plurality of MO, as report configuration 503 in Fig. 5 identify 505 and measure sign 506 and be associated with two different MO by measurements respectively, measuring object configure 501 and measuring object configure 502.
In the LTE system, measure, the measuring reference signals of any community is CRS, and no matter UE measures which community on which frequency, and the PCI that UE all can detect by blind check extrapolates the time-frequency domain position of CRS on each community, and then CRS is measured.
After introducing measuring reference signals CSI-RS, the L3 measuring management method of method one based on CSI-RS specifically comprises:
