When embodiment of the invention user terminal sends measurement report at needs, sub-district corresponding district sign and frequency indication information that definite needs are measured, the measurement report that will comprise cell ID and frequency indication information sends to network side, and its medium frequency indication information is used to indicate whether the sub-district at this sub-district and user terminal place is with frequently.Owing to dwindled the capacity of measurement report, can use lower code check to come the transmission measurement report, thereby guarantee the reliability of measurement report uplink, reduce the sub-district time delay for switching, having reduced the long-time measurement report of appearance can't report, and can't carry out the situation that switch the sub-district.
Below in conjunction with Figure of description the embodiment of the invention is described in further detail.
As shown in Figure 1, the system of embodiment of the invention transmission measurement report comprises: user terminal 10 and base station 20.
In specific implementation process, user terminal 10 is measured according to the Neighboring Cell List of RNC configuration, and when the measured value of certain adjacent area satisfies the trigger condition of measurement report, user terminal 10 generates and sends measurement report.
The mode that triggers the user terminal to send up measurement report includes but not limited to a kind of in the following triggering mode:
The trigger condition of the trigger condition of the trigger condition of 1G measurement report, 2A measurement report, 3D event measurement report.
1G is the same-frequency measure reporting trigger event, when the signal strength signal intensity of measured co-frequency neighbor cell becomes the strongest or path loss becomes minimum (more excellent than current area), will trigger the 1G measurement report so and report;
2A is the different-frequency measure reporting trigger event, becomes minimum (more excellent than current area) when measured iso-frequency adjacent community signal strength signal intensity becomes the strongest or path loss, will trigger the 2G measurement report so;
The 3D incident is an isosystem measurement report triggering incident, when the measuring amount of different system cell becomes best sub-district (more excellent than current area), reports the 3D measurement report this moment.Here the measuring amount of mentioning can be RSSI (Received Signal Strength Indicator, received signal intensity is indicated) or RSRP (Referencesignal received power, Reference Signal Received Power) or RSRQ (Reference Signal Received Quality, Reference Signal Received Quality).
Wherein, the capacity of the measurement report of embodiment of the invention user terminal 10 transmissions is less than the capacity of the measurement report of stipulating in the 3GPPTS25.331 agreement
In specific implementation process, the measurement report of user terminal 10 structures can also comprise one or more in the following content:.
Measure RSCP (Received Signal Code Power, the received signal code power) value of sign, PCCPCH (Primary Common Control Physical Channel, Primary Common Control Physical Channel).
If user terminal 10 is the measurement reports that report at synchronous direct-cut operation, then measurement report can also comprise activationary time.
Certainly, can also comprise as required: the relevant information of type of message, integrity protection, measurement ID, one or more in other information such as the cell scrambling of trigger event ID and a plurality of sub-districts, measured value.
Cell ID: because RNC is when the user terminal configuration is tabulated with frequency and alien-frequency district, (using integer 0...31 to represent 32 sub-districts) all carried out numbering with cell ID in each adjacent sub-district, so the cell ID that user terminal 10 reports (comprising that co-frequency cell identifies and alien-frequency district identifies) uses the identical numbering of the correspondence of network configuration to identify corresponding same frequency or alien-frequency district, which sub-district what network had also just been known correspondence after receiving like this is.For integer 0...31, can represent by 5 bit physical layer signalings.
In addition, for the cell switch process that strengthens, this cell ID can report the sub-district corresponding district sign that relates in the pre-configured process, because pre-configured sub-district number is less, therefore can use less physical layer signaling to represent.For example, if pre-configured sub-district number is 6 to the maximum, can represent by 3 bit physical layer signalings so.
Accordingly, user terminal 10 reporting subdistricts signs, network side can determine which sub-district satisfied trigger condition in conjunction with frequency indication information and cell ID, just which sub-district is the purpose sub-district of switching.
The frequency indication information: the frequency indication information is represented common frequency measurement (for example 1G measures) or different-frequency measure (for example 2A), and physical layer signaling can be indicated by 1 bit, and for example this bit is set to ' 1 ' expression common frequency measurement, ' 0 ' expression different-frequency measure.
Measuring sign (ID) is the unique identification of RNC and certain measurement of terminal iidentification.For with a kind of measurement type, RNC may dispose different measurement ID, and each measurement of measuring the Id correspondence just comprises sub-district ID and with frequently or different-frequency measure.If RNC for a kind of measurement type configuration a plurality of measurement ID, terminal just needs reporting measurement ID so, RNC receives that the measurement report that to measure the just definite place of ID specifically be that measurement triggering reports like this.
Activationary time: activationary time uses integer 0...255 to represent CFN (Connection Frame Number) usually, and physical layer signaling can be represented by 8 bits.In addition, in order to reduce handover delay, the activationary time point of present a kind of optimization is only represented Connection Frame Number by integer 0...127, can represent by 7 bit physical layer signalings this moment;
The effect of activationary time is to allow network all switch to new sub-district in the identical time with user terminal, avoids data interruption.
The RSCP value of PCCPCH: the scope of RSCP value is (0...91), can represent by 7 bit physical layer signalings;
The concrete signal magnitude in RSCP value representation sub-district of PCCPCH is convenient to network and is given ordering of purpose sub-district and switch decision.
If need to contain activationary time (being the approximate time that new argument is handled in the base station) in the measurement report, the activationary time point that user terminal 10 carries in sending measurement report can be that the skew of activationary time point adds the time point that sends measurement report, and the skew of activationary time point is that network is notified to user terminal in the pre-configured Target cell stage before.
If need to contain the RSCP value of PCCPCH in the measurement report, user terminal 10 needs the RSCP of the PCCPCH of measurement sub-district, and the received signal code power value that measures is placed measurement report.
Wherein, user terminal 10 can place signaling with measurement report, sends by physical layer control channel and/or physical layer Traffic Channel.
If user terminal 10 sends by physical layer control channel, then can pass through E-RUCCH (E-DCH Random access Uplink Control Channel, strengthen dedicated channel and insert ascending control channel at random) send, because control channel generally all is to use the modulation system of low order, for example QPSK (Quadrature Phase Shift Keying, quarternary phase-shift keying (QPSK)) etc. uses lower code check, compare the modulation system of Traffic Channel higher-order, have higher reliability;
If user terminal 10 sends by the physical layer Traffic Channel, then can pass through DPCH (DedicatedPhysical Channel, DPCH) or E-PUCH (E-DCH Physical Uplink Channel, the dedicated channel physical uplink channel of enhancing) send.
In order further to improve transmission reliability, user terminal 10 can also send (that is to say and send twice) by physical layer control channel and physical layer Traffic Channel respectively with measurement report; As long as network side is received one of them measurement report and just can be carried out cell switch determining, ignores the another one measurement report.
Wherein, satisfy trigger condition, when need measuring a plurality of sub-district, need check whether the signaling of carrying measurement report can carry all measurement reports if user terminal 10 defines a plurality of sub-districts.
Concrete, user terminal 10 is measured a plurality of sub-districts at needs, and the signaling of the carrying measurement report quantity that can carry measurement report places a signaling with all measurement reports when being not less than the number of cells that satisfies the measurement report report condition;
Measure a plurality of sub-districts at needs, and the quantity that the signaling of carrying measurement report can be carried measurement report is when satisfying the number of cells of measurement report report condition, all measurement reports are placed a plurality of signalings, or according to the priority of sub-district, select N high sub-district of priority to measure, and the measurement report that obtains placed a signaling, wherein N is a positive integer, and is not more than the quantity that the signaling of carrying measurement report can be carried measurement report.
Here the priority of sub-district can be adjudicated according to conditions such as cell signal strength, channel qualities.Such as judging according to signal strength signal intensity, then can sort from big to small according to cell signal strength, if can only report a sub-district, then preferentially select the sub-district of signal strength signal intensity maximum, if can report a plurality of sub-districts, several sub-districts before then can selecting.
Need to prove that the embodiment of the invention is not limited to signal strength signal intensity and channel quality, other modes that can determine native region priority are suitable for the embodiment of the invention equally.
If user terminal 10 need send measurement report by E-RUCCH, can adopt the signaling format of present E-RUCCH, referring to Fig. 6.
The signaling format of E-RUCCH comprises following territory:
Serving cell and adjacent sub-district path loss information SNPL (5bits); This information is used for auxiliary Node B and estimates the interference level to adjacent sub-district that each terminal may be brought, and then distributes corresponding absolute power mandate and physical resource mandate;
Terminal power headrooms information UPH (5bits); UPH represents the ratio of terminal maximum transmit power and power control base unit weight Pe-base and Serving cell path loss sum;
Total E-DCH buffer status TEBS (5bits); TEBS represents the data total amount of all logic channels of terminal, comprises the data volume that rlc layer etc. is to be transmitted or retransmit;
Highest priority logical channel buffer status HLBS (4bits); The data total amount of expression highest priority logical channel is a relative ratio with respect to TEBS;
Highest priority logical channel ID, i.e. HLID (4bits), indication has the logic channel of limit priority to be sent such as data; If have the logic channel of a plurality of limit priorities to exist simultaneously, select the logic channel ID of buffer memory occupation proportion maximum to report so;
The temporary transient identification code E-RNTI of E-DCH wireless network (16bits); Be used to discern the E-PUCH wireless network identification code of UE.
Concrete, user terminal 10 can be made as ' 00000 ' with TEBS, and it is non-' 0000 ' that HLBS is set to, and non-' 1111 ' value represents to carry the E-RUCCH of measurement report.For example ' 0000 ' and ' 1111 ' any one middle value can be used.0001 E-RUCCH that represents to carry measurement report for example.
Need to prove that the embodiment of the invention is not limited to the mode of the E-RUCCH of above-mentioned expression carrying measurement report, other modes that can represent to carry the E-RUCCH of measurement report all are to use the embodiment of the invention.
If user terminal is the measurement report that reports at asynchronous direct-cut operation, can use 6 bits in the signaling of E-RUCCH to represent the sub-district ID of 5 bits and the frequency indication information of 1 bit, other bit is reserved; Can also use 4 bits in the signaling of E-RUCCH to represent the sub-district ID of 3 bits and the frequency indication information of 1 bit, other bit is reserved;
Further can also use reserved bit to represent the measurement report of optional RSCP value, measurement sign or other sub-district.
If user terminal is the measurement report that reports at synchronous direct-cut operation, can use 6 bits in the signaling of E-RUCCH to represent the sub-district ID of 5 bits and the frequency indication information of 1 bit, 8 bits or 7 bits are represented activationary time, other bit is reserved; Can also use 4 bits in the signaling of E-RUCCH to represent the sub-district ID of 3 bits and the frequency indication information of 1 bit, 8 bits or 7 bits are represented activationary time, and other bit is reserved.
Further can also use reserved bit to represent the measurement report of optional RSCP value, measurement sign or other sub-district.
If carry out the handover trigger report reporting of a plurality of sub-districts: user terminal 10 can also use reserved bit to represent the handover trigger report of other sub-district, for example situation of asynchronous direct-cut operation; The signaling that can also repeatedly send E-RUCCH realizes the purpose with the handover trigger report reporting of a plurality of sub-districts.
If user terminal 10 need send measurement report by DPCH or E-PUCH, because the carrying bit number obviously reduces, compare the measurement report that transmits under the same terms than multi-bit, can reduce the code check of transmission, thereby improve the reliability of transmission.In addition, also the measurement report of a plurality of sub-districts can be transmitted by DPCH or E-PUCH simultaneously.
In order further to improve the success rate and the reliability of transmission, can introduce feedback mechanism to the physical layer signaling of carrying measurement report.
Concrete, user terminal 10 can start timer after sending measurement report to network side, if do not receive the reception success message from network side before the timer expiry, then resend measurement report.The time of timer can be set as required.
Accordingly, the reception success message is returned to user terminal 10 in base station 20 after receiving measurement report.
For example, receiving success message can carry by E-AGCH or HS-SCCH.Can introduce a kind of special E-AGCH (E-DCH Absolute Grant Channel, strengthen dedicated channel E-DCH absolute grant channel) or HS-SCCH (Shared Control Channel for HS-DSCH, the shared control channel of high-speed downstream Physical Shared Channel HS-DSCH) carries or use normal E-AGCH or HS-SCCH to carry.
Wherein, base station 20 is placed in FP (frameprotocol, Frame Protocol) frame or NBAP (Node B application protocol, the base station applies agreement) signaling in the measurement report after receiving measurement report, sends to RNC.
If base station 20 is placed in the FP frame in the measurement report, then base station 20 can increase a part of content and is used for carrying content in the measurement report on present FP frame basis.Such as, in existing E-DCH FP frame, increase the content of the measurement report in the embodiment of the invention, the number of MAC-is PDUs in the existing E-DCH FP frame can be changed to 0 and do not carry MAC-is PDUdescriptor and be used to indicate RNC this is the E-DCH FP frame that carries measurement report.
Need to prove that the embodiment of the invention is not limited to aforesaid way, other modes that increased the content of the measurement report in the embodiment of the invention in existing E-DCHFP frame are suitable for the embodiment of the invention equally.
The content in the measurement report can also be carried in base station 20 in new FP frame, referring to Fig. 7.Among Fig. 7, cell ID can be 5bit, and FI is the frequency indication information, and CFN is the activationary time point.
Need to prove that the form of new FP frame is not limited to shown in Figure 7, other forms that can carry the FP frame of the content in the measurement report are suitable for the embodiment of the invention equally.
If base station 20 is placed in the NBAP signaling in the measurement report, the content of increase can be referring to table 1.Table 1 is a kind of manifestation mode, and other manifestation modes that can comprise the content in the measurement report all are to use the embodiment of the invention.
