Specific embodiment
Basic thought of the invention is：Serving cell is the UE configurating channel quality uploading thresholdings being initially accessed；UE is carried out
The channel quality measurement of adjacent area, and report the adjacent area of thresholding to report Serving cell more than or equal to channel quality SINR value；Clothes
Business cell selecting collaboration cell from the adjacent area that UE is reported, and be that UE configures CoMP metrical informations according to the cooperation cell selected；
UE carries out CoMP measurements according to CoMP metrical informations, and the result measured according to CoMP, and SINR value is continuously less than into channel quality
The cooperation cell of thresholding is reported, needs removal list to report Serving cell by multipoint cooperative.
The present invention is described in further detail again below by drawings and the specific embodiments.
The present invention provides a kind of measurement collocation method of multipoint cooperative system, and Fig. 2 is that the present invention realizes multipoint cooperative system
Measurement collocation method schematic flow sheet, as shown in Fig. 2 the method is comprised the following steps：
Step 201, Serving cell is the UE configurating channel quality uploading thresholdings being initially accessed；
Specifically, when UE is initially accessed Serving cell, Serving cell is that the UE configures metrical information, the measurement of the configuration
Information includes that UE needs the side of the ID of the adjacent area of measurement, the information of the adjacent area of needs measurement and UE to Serving cell reporting information
Formula etc.；In the present embodiment, it is necessary to measurement adjacent area information be reflect channel quality Signal to Interference plus Noise Ratio (SINR,
Signal to Interference plus Noise Ratio) value；
Additionally, Serving cell also needs to be UE configurating channel quality uploading thresholdings, optionally, a letter can be configured for UE
Unit, the cell is used to record and preserve channel quality to report thresholding.
Step 202, UE carries out the channel quality measurement of adjacent area, and SINR value is reported into thresholding more than or equal to channel quality
Adjacent area reports Serving cell；
Specifically, the metrical information that UE is configured according to Serving cell carries out the channel quality measurement of adjacent area, that is, measure adjacent area
SINR value, and judge that the SINR value of adjacent area measured reports the size of thresholding, UE with the channel quality of Serving cell configuration
Only the adjacent area of thresholding is reported to report Serving cell more than or equal to channel quality SINR value；Wherein, reporting schemes are small to service
Area configuration metrical information in carry reporting information mode, for example, can by Physical Uplink Control Channel (PUCCH,
Physical Uplink Control Channel) information reporting is to Serving cell；Here, SINR value is less than on channel quality
Reporting the adjacent area of thresholding will not report Serving cell, so, it is possible to reduce the signaling in CoMP system between UE and Serving cell
Communication quality, is thus advantageous to improve system data throughput.
Step 203, Serving cell selecting collaboration cell from the adjacent area that UE is reported, and be UE according to the cooperation cell selected
Configuration CoMP metrical informations；
Specifically, after UE enters CoMP regions, Serving cell selecting collaboration cell in the adjacent area that UE is reported chooses knot
Shu Hou, Serving cell is referred to as the main serving cell of cooperation cell collection, and now, Serving cell passes through Physical Downlink Control Channel
The channel quality that (PDCCH, Physical Downlink Control Channel) message informing UE terminates adjacent area is reported, together
When Serving cell be that UE configures CoMP metrical informations, and the CoMP metrical informations are handed down to by UE by reallocation message；Wherein,
CoMP metrical informations include that multipoint cooperative increases modification list (CoMPToAddModList) and multipoint cooperative and will remove list
(CoMPToRemoveList)；The content of CoMPToAddModList is the ID of the cooperation cell that UE needs measurement,
The content of CoMPToRemoveList be with last Serving cell be UE configuration CoMP metrical informations compared with, from
The ID of the cooperation cell deleted in CoMPToAddModList；For example, including cooperation cell #4, # in CoMPToAddModList
5th, #6 and #7, and last Serving cell is small comprising cooperation in the CoMPToAddModList in UE configuration CoMP metrical informations
Area #3, #4, #5 and #6, then include cooperation cell #3 in CoMPToRemoveList；
Additionally, Serving cell can also include that cell increases modification list in configuring CoMP metrical informations for UE
(cellsToAddModList) and cell will remove list (cellsToRemoveList) etc., CoMP metrical informations include this two
Individual list belongs to prior art, and UE falls within prior art, repeats no more here according to the operation that the two lists are carried out；
Optionally, channel quality can also be reported thresholding to be sent to UE again by Serving cell, to prevent UE from not preserving elder generation
Before the channel quality that receives report thresholding, or preserve but be deleted because long-time is not used, UE is carrying out CoMP measurements
When or when providing adjacent area for Serving cell next time, it is possible to use the channel quality reports the thresholding to carry out cooperation cell or adjacent area
Screening.
Step 204, UE carries out CoMP measurements according to CoMP metrical informations, and the result measured according to CoMP, by SINR value
The cooperation cell of thresholding is continuously reported less than channel quality, needs removal list to report Serving cell by multipoint cooperative；
Specifically, after UE receives the CoMP metrical informations that Serving cell is issued, original metrical information is updated into CoMP
Metrical information, and proceed by CoMP measurements, that is, measure the SINR value of the cooperation cell in CoMPToAddModList；Set one
Multipoint cooperative needs to remove list (CoMPNeedToRemoveList), and UE will meet the cooperation cell that cooperation cell removes condition
It is included in CoMPNeedToRemoveList and reports Serving cell；
Cooperation cell removes condition and refers to the SINR value of cooperation cell continuous interior less than channel quality for a period of time
Report thresholding；It can be that Serving cell is in advance UE configurations that cooperation cell removes condition and a period of time, for example, at this section
Between be 256ms, UE measurement SINR value cycle be 10ms, so if UE measurement cooperation cell SINR value be less than for continuous 26 times
Channel quality reports thresholding, then the cooperation cell is reported Serving cell by UE；
Here, SINR value is continuously reported the cooperation cell of thresholding to report Serving cell and can adopted by UE less than channel quality
With two kinds of periodic report mode and reporting events mode, if wherein reporting events mode refer to a SINR value occur it is continuous
Less than the cooperation cell that channel quality reports thresholding, the cooperation cell is just reported Serving cell by UE.
Step 205, Serving cell judges that cooperation needs to remove whether list is empty, if it is, measured according to CoMP
Result is processed, if not, needing to reselect cooperation cell, performs step 203；
Specifically, after receiving the CoMPNeedToRemoveList that UE is reported, Serving cell judges
Whether CoMPNeedToRemoveList is empty, if it is, represent without the cooperation cell for needing to be adjusted, then basis
The result of CoMP measurements is processed, and the handling process belongs to the regulation flow in existing LTE protocol, repeats no more here；Such as
Really no, i.e. CoMPNeedToRemoveList is non-NULL, then Serving cell is needed according in CoMPNeedToRemoveList
Cooperation cell carries out the adjustment of cooperation cell collection, that is, reselect cooperation cell, performs step 203.
