With the measurement of filtering, the present invention is referred to as layer 1 (Layerl, L1) measurement.
Wherein L3, which measures obtained quality of wireless channel, can assist eNB to carry out the wireless resource management such as CMC, ICIC.Such as

In order to meet the performance indicator of LTE-A, especially up to LTE-A is to the performance requirement of Cell Edge User, CoMP
Transmission technology is suggested.CoMP transmission technology is counted as improving community marginal user performance, effectively inhibits inter-cell interference
One of important technology.Lte-a system can increase the covering of high data rate by CoMP technologies, to improve cell edge
Handling capacity, further increase throughput of system.So-called CoMP refers to the multiple eNB detached on geographical location, or is claimed multiple
Transmission node (Transmission Point, TP) participates in and the data transmission of the same UE.It is illustrated in figure 2 a kind of portions CoMP
Affix one's name to schematic diagram of a scenario.3 cells adjacent to each other in Fig. 2, the base station 200 of cell 1, the Remote Radio Unit 201 of cell 2
The Remote Radio Unit 202 of (Remote Radio Head, RRH), cell 3 shares the channel information of UE 203, distributed intelligence,
And combined dispatching is carried out based on these information, codetermine scheduling and/or the beam shaping of UE.Wherein base station 200 is drawn with radio frequency
It is connected with optical fiber between remote unit 201 and 202.
In order to meet LTE-A high-throughputs, the requirement of high transfer rate especially reaches LTE-A and is covered to enhancing hot spot, is small
The demand of area edge, in-door covering etc. is introduced into some low power nodes on the basis of traditional isomorphism cellular network.Such as Fig. 3
For a kind of heterogeneous network deployment scenario.Base station 300 constitutes macrocell 1, and there are two low-power for the interior deployment of coverage area of macrocell 1
For node LPN301 and LPN302 to enhance hot spot covering, overlay area 2 is the signal cover of LPN 301, overlay area 3
For the coverage area of LPN 302.It is connected with optical fiber between base station 300 and LPN 301, LPN 302.
To further increase the system performance of heterogeneous network, CoMP transmission technology can be used in combination with heterogeneous network, than
As in Fig. 3, for UE 303 simultaneously in the coverage area of macrocell 1 and LPN 301, base station 300 and LPN 301 can be common
Participate in the transmission of UE 303.Similarly, UE 304 is located at simultaneously in the coverage area of macrocell 2 and LPN 302, base station 300 and LPN
302 can participate in the transmission of UE 304 jointly.
As Fig. 3 heterogeneous network in, when operator deployment, can be by the overlay area 2 of LPN 301, the area of coverage of LPN302
Domain 3, which separately designs, is independent cell, that is, is respectively designed with independent synchronizing channel, Physical Cell Identifier (Physical Cell
Identity, PCI), the cell of CRS etc., at this time overlay area 2 can be denoted as cell 2, overlay area 3 can be denoted as cell 3.
The overlay area 3 of the overlay area 2 of LPN 301, LPN 302 can not also be designed when operator deployment and be independent cell,
For example it is not 3 independent design synchronizing channel of overlay area 2 and/or overlay area, PCI, CRS etc., or setting overlay area 2
And/or the synchronizing channel of overlay area 3, PCI, CRS are identical as macrocell 1.
Unless otherwise instructed, the above base station, LPN, RRH etc. are referred to as node (Point) in the subsequent description of the present invention.
CoMP technologies need that suitable transmission node is selected to participate in transmitting jointly, to select suitable transmission node, CoMP
Technology proposes the concept of several resource collections.As shown in figure 4,400 black dotted lines areas encompassed are CoMP resource managements
Gather (CoMP Resource Management Set), UE executes L3 to the resource in CoMP resource management set and measures simultaneously handle
Measurement feedback gives network-side (such as base station), network-side that the measurement result of the feedback can be utilized to select CoMP measurement sets
It closes, has selected 401 solid black lines areas encompassed as shown in Figure 4.UE executes L1 to the resource in CoMP measuring assemblies and surveys
It measures and measurement result is reported to network-side, network-side can utilize the measurement result selection CoMP cooperation set of the feedback,
402 shadow region has been selected as shown in Figure 4.Node in CoMP cooperations set 402 participates in determining the scheduling of UE405 jointly
And/or beam shaping, and actual participation and UE405 transmission can be only CoMP cooperation set in part of nodes, such as
Node 403 and node 404.
It should be noted that as it was noted above, when operator deployment LPN the overlay area of LPN can be deployed as independence
Cell can not also be deployed as individual cell.It is expected that operator can also be as needed by base when disposing base station in the future
Covered regional deployment of standing is independent cell or is not deployed as individual cell.If the region quilt that certain nodes are covered
Deployment is independent cell, then UE can measure CRS and CRS is fed back to network-side, and network-side can utilize the survey of the CRS
It measures result and selects CoMP measuring assemblies, CRS can also be measured when UE measures the individual cell in CoMP set.Conversely,
If the region that certain nodes are covered is not deployed as independent cell, needs to introduce the specific reference signals of UE, such as believe
Channel state information reference signal (Channel-State Information reference Signal, abbreviation CSI-RS).Net
The configuration of network end needs in the CSI-RS resource to CoMP resource management set of the node measured, and UE carries out L3 to CSI-RS and measures simultaneously
Network-side is given measurement feedback, and network-side selection node simultaneously configures the CSI-RS resource of corresponding node to CoMP measuring assemblies
In.
L3 based on CSI-RS is measured, and the configuration management of CoMP measuring assemblies is can be used in CoMP technologies, with nothing
The continuous evolution of line communication network, the L3 measurements based on CSI-RS can be used for CMC, ICIC etc..It is detailed below to be based on
The L3 measuring management methods of CSI-RS.
Method one,
It configures measurement based on CRS and based on the measurement of CSI-RS in same measurement object, passes through measuring configuration relationship
Determine that measuring reference signals, UE execute measurement.
It wherein configures in the measurement based on CRS and the measurement based on CSI-RS and same measurement object, refers to for one
Specific frequency configures a measurement object, configures the CSI-RS resource for needing to measure simultaneously in the measurement object.
In LTE system, eNB can be the UE of wireless heterogeneous networks (Radio Resource Control, RRC) connection status
It configures L3 to measure, to meet CMC, the wireless resource management demand such as ICIC.For being measured in LTE system, specifically, eNB is
UE configurations include following measurement parameter：

The frequency of one LTE；
2, report configuration (Reporting Configuration, RC) configures：ENB can be that UE configures multiple RC, each
The criterion (for example, periodic triggers, event triggering etc.) that configuration report triggers in RC, (reference signal receives work(to report triggering amount
Rate (Reference Signal Received Power, RSRP) or Reference Signal Received Quality (Reference
Signal Received Quality, RSRQ)) and other parameters.
3, mark (Measurement Identity, MID) configuration is measured：ENB can be that UE configures multiple MID.
LTE L3 measuring management models as shown in Figure 5, each MID are associated with MO and RC, as measured mark in Fig. 5
Know 505 correlation measurement objects configuration 501 and report configuration 503.By configuring multiple MID, a MO can be associated with multiple RC, such as
In Fig. 5 measurement object configuration 502 is reported and is matched by measuring mark 506 and measuring the RC that be respectively associated two different of mark 507
Set 503 and report configuration 504.Equally, by configuring multiple MID, a RC can be associated with multiple MO, such as report configuration in Fig. 5
503 respectively by measuring mark 505 and measuring the MO that be associated with two different of mark 506, i.e. measurement object configuration 501 and measurement
Object configuration 502.
It is measured in LTE system, the measuring reference signals of any cell are CRS, which in which frequency no matter UE measure
A cell, the PCI that UE can be detected by blind examination extrapolate the time-frequency domain position of CRS in each cell, so to CRS into
Row measures.
It introduces after measuring reference signals CSI-RS, L3 measuring management method of the method one based on CSI-RS specifically includes：
Measurement based on CRS and the measurement based on CSI-RS are configured in same measurement object, and UE passes through measuring configuration
Relationship determines that measuring reference signals, UE execute measurement.
