Description
Technical field
The present invention relates to wireless communication technology field, particularly, the present invention relates to measure the method and apparatus of the quality of reception of cell reference signals.
Background technology
Along with to being fit to the increase of mobile communication spectrum requirement, require the uplink and downlink of LTE can be operated in widely in the frequency band range.Under the situation of single carrier, the spectrum allocation may of LTE can be at 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz.In same zone, operator can dispose the system bandwidth of each residential quarter flexibly according to band resource and the business load of oneself.
Subscriber equipment (UE) is in moving process, and in order to keep residing in proper cell and professional continuity, subscriber equipment need continue current service cell and adjacent residential quarter are measured.The measuring amount of subscriber equipment comprise reference symbol accept power (RSRP) and reference symbol accept quality (RSRQ), RSRP is the received power of reference signal, measurement be power on the cell reference signals place resource element (Resource Element).RSRQ is the quality of reception of cell reference signals, and its value equals N*RSRP/ (RSSI), and wherein, N is the number of Resource Block, and RSSI is the volume indicator that receives signal, comprises the power from Serving cell, non-service cell and thermal noise.In order to guarantee that the network equipment obtains above-mentioned measuring amount accurately, the Measured Boundary condition of RSRP and RSRQ and certainty of measurement require to have clear and definite definition in the standard of LTE.Simultaneously in order to reduce complexity and the power consumption that subscriber equipment is realized, RSRP and RSRQ certainty of measurement only require subscriber equipment to measure at 6 Physical Resource Block (Physical Resource Block) to the midbandwidth of Serving cell and neighbor cell.
Measurement and the reporting measurement message of Serving cell and neighbor cell can configuration UE be carried out in current LTE network equipment base station (eNB), thereby support the mobility control to UE.In order to limit the signaling quantity that sends to eNB, measure and report activity to dispose to trigger by eNB to measure and report.The LTE single-carrier system has defined following time triggering and has reported criterion:
Event A1: Serving cell is better than absolute door limit value;
Event A2: Serving cell is poorer than the absolute door limit value;
Event A3: adjacent residential quarter is better than the side-play amount with respect to Serving cell;
Event A4: adjacent residential quarter is better than absolute door limit value.
UE triggers a certain event when the entry condition of appointment is satisfied in one or more residential quarter, eNB can arrange some employed configurable parameters in these conditions influences entry condition, be trigger event, entry condition satisfies condition in the triggered time of network configuration (time to trigger) at least always.
Under the scene of some network design, operator is chosen in the residential quarter of same frequency band deploy different bandwidth.Under deployment scenario as shown in Figure 1, operator has disposed system bandwidth respectively on frequency band be the residential quarter of 10MHz and 5MHz, because adjacent bandwidths is 0 between the residential quarter of 5MHz.The protection of 5MHz existence at interval, bandwidth are that the interference rank of 6 PRB of center of housing estate of 10MHz and the interference rank of other PRB have difference.According to its specific deployments condition, the demand that has proposed expansion RSRQ measurement bandwidth in the present standardized discussion reports the quality of reception more accurately to guarantee UE.Measure bandwidth and depend on the bandwidth of operation of receiver radio frequency device and the processing bandwidth of UE base band.On the other hand, the implementation complexity of subscriber equipment and power consumption also are closely related with the bandwidth of operation of radio-frequency devices and the processing bandwidth of UE base band.Measure bandwidth thereby enlarge, certainly will bring subscriber equipment implementation complexity and power consumption to increase.
Simultaneously, from the angle of systematic function, disposed at neighbor cell under the application scenarios of different system bandwidth, for the user who is in cell edge, the received signal quality of 6 PRB in center has significant difference with the actual signal quality that receives.Yet, for the user of center of housing estate, also not obvious with the difference of the actual signal quality that receives based on the received signal quality of 6 PRB in center.
Therefore, be necessary to propose the otherwise effective technique scheme, solved in adjacent cell configuration under the application scenarios of different bandwidth the problem of the accurate measure R SRQ of user equipment (UE).
Summary of the invention

Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein identical or similar label is represented identical or similar elements or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the present invention, and can not be interpreted as limitation of the present invention.
The invention provides the method that a kind of UE accurately measures the RSRQ of Serving cell and neighbor cell.Disposed the application scenarios of different system bandwidth in the base station; for example under the deployment scenario as shown in Figure 1; because the existence of protection band separation; when UE is in cell edge; the RSRQ of 6 PRB in center of the part residential quarter of measuring significantly is lower than other PRB; in order to guarantee that UE reports RSRQ more accurately, UE need enlarge the measurement bandwidth of RSRQ under certain condition.But the measurement bandwidth that meanwhile, enlarges RSRQ certainly will be brought the power consumption that improves UE.
In order to realize the present invention's purpose, the embodiment of the invention has proposed a kind of method of measuring the quality of reception of cell reference signals, may further comprise the steps: user equipment (UE) obtains the bandwidth information of measuring the broadband reference signal quality of reception; When meeting the preset trigger condition, described UE measures at the enterprising line width band of the bandwidth of obtaining Reference Signal Received Quality; Described UE reports the described broadband reference signal quality of reception to measure.
As shown in Figure 2, measure the method flow diagram of the quality of reception of cell reference signals for the embodiment of the invention, may further comprise the steps:
S110: user equipment (UE) obtains the bandwidth information of measuring the broadband reference signal quality of reception.
The bandwidth information that subscriber equipment obtains among the step S110 is that the indication subscriber equipment is in the bandwidth information of the Reference Signal Received Quality that surpasses 6 the Physical Resource Block measurement Serving cells in center or neighbor cell.Broadband RSRQ measurement refers to UE at the RSRQ above measurement Serving cell or neighbor cell under the bandwidth of 6 Physical Resource Block in center in the inventive method.
S120: when meeting the preset trigger condition, UE measures at the enterprising line width band of the bandwidth of obtaining Reference Signal Received Quality.
The condition that triggering broadband RSRQ among the scheme step S120 that the present invention proposes measures can the base station by the condition of signaling configuration, also can be predefined condition in the standard, namely UE obtains trigger condition information by following any one mode:
UE receives the base station by the trigger condition of signaling configuration;
