Description
Technical field
The present invention relates to the mobile communication technology field, particularly a kind of method and user terminal of measuring the adjacent area.
Background technology
In mobile communication system, along with mobile subscriber's movement, the employed user terminal of this mobile subscriber (User Equipment, UE) may move to from the coverage of current service cell the coverage of another residential quarter.When the radio signal quality of UE Serving cell is relatively poor, usually UE need to be switched to the better adjacent cell of radio signal quality (abbreviation adjacent area), this process is called cell reselection/switching.
Before carrying out cell reselection/switching, UE need to receive signal at the frequency of relevant adjacent area, and the radio signal quality of measurement adjacent area, decide the Target cell for the treatment of gravity treatment by UE under the RRC_IDLE state, under the RRC_CONNECTED state measurement report is reported network, decide to be switched Target cell by network.Described adjacent area may with current service cell with frequently, also may with the current service cell alien frequencies, when current service cell and adjacent area alien frequencies, described measurement is called different-frequency measure.
LTE (Long Term Evolution, the Long Term Evolution plan) provide a kind of measurement for carrying out different-frequency measure under the RRC_CONNECTED state idle window (GAP) in, GAP in time the cycle occur, the cycle is divided 40ms and 80ms two kinds, the duration is 6ms.
In the LTE system, measuring amount under the RRC_CONNECTED state can be Reference Signal Received Power (the Reference Signal Received Power of residential quarter, RSRP), what RSRP measured is on the Measurement bandwidth of this place, residential quarter frequency, carry the linear power mean value of physical resource unit (Resource Element) of " the specific reference signal in residential quarter (Cell-specific Reference Signal; CRS) " of this residential quarter, unit is dBm.Measuring amount under the RRC_CONNECTED state can also be Reference Signal Received Quality (the Reference Signal Received Quality of residential quarter, RSRQ), RSRQ need to measure RSRP and received signal strength indicator (the Received Signal Strength Indicator of residential quarter, RSSI), wherein, rssi measurement be on the Measurement bandwidth of this place, residential quarter frequency, the total received power of all Physical Resource Block (Resource Block), the power that comprises people having a common goal's (Co-Channel) Serving cell and adjacent cell, neighboring trace (Adjacent Channel) disturbs, thermal noise etc.RSRQ is defined as that (N * RSRP/RSSI), unit is dB, and wherein, N is illustrated in the Physical Resource Block number on the Measurement bandwidth of this place, residential quarter frequency.
Need to use descending sub frame in the LTE system to the measurement of above-mentioned measuring amount.TD-LTE is a kind of of LTE system, and its frame structure comprises: radio frames (Radio frame), and the length of a radio frames is 10ms; Field (Half frame), the length of a field is 5ms, two fields form a radio frames; Subframe (Subframe), the length of a subframe is 1ms, five subframes form a field, and namely ten subframes form a radio frames, and subframe is divided into again conventional subframe (Normal Subframe) and special subframe (Special Subframe); Time slot (Time Slot), the length of each time slot is 0.5ms, and each time slot has by 6 or 7 symbols (OFDM symbol) formation, and two time slots form a conventional subframe.Wherein, conventional subframe can be configured to sub-frame of uplink (UL Subframe) and descending sub frame (DL Subframe), in the TD-LTE system is to use this descending sub frame to measure sub-frame configuration scheme such as following table 1 commonly used:
Table 1
Wherein, D represents descending sub frame, and U represents up substation, and S represents special subframe.
For the TD-LTE system, can use above-mentioned 7 kinds of configurations to carry out the uplink-downlink configuration of flexibility and changeability, different uplink-downlink configuration can be used in the alien frequencies adjacent area.In various uplink-downlink configuration forms, what be fixed as descending sub frame only has subframe 0 and subframe 5.Therefore, in the prior art, can only measure subframe 0 and subframe 5 by the duration at GAP, and the duration of a GAP is 6ms, remove consuming time on switching of frequency, basically only have 5.5ms to be used for measuring, thereby can only measure the adjacent area on the frequency, thus, so that the utilance of GAP is not high.In addition, because a GAP can only measure the adjacent area on the frequency, it is long to cause finishing wheel measurement duration, thereby has reduced the time that terminal can be slept, and has increased the power consumption of terminal.

Embodiment
Be described in further detail below in conjunction with method and the user terminal of the drawings and specific embodiments to measurement provided by the invention adjacent area.According to the following describes and claims, advantages and features of the invention will be clearer.It should be noted that accompanying drawing all adopts very the form of simplifying, only in order to convenient, the purpose of the aid illustration embodiment of the invention lucidly.
Embodiment one
Please refer to Fig. 1, it is the schematic flow sheet of method of the measurement adjacent area of the embodiment of the invention one.As shown in Figure 1, the method for measurement adjacent area specifically comprises the steps: in the present embodiment
At first, execution in step S10: the cell conditions of obtaining each frequency.In the present embodiment, the cell conditions of each frequency comprises: the residential quarter number of each frequency, ID and the timing information of each residential quarter.Concrete, obtain master sync signal (PSS, Primary Synchronization Signal) and auxiliary synchronous signals (SSS, Secondary Synchronization Signal), according to the cell conditions of each frequency of acquisition of information entrained in master sync signal and the auxiliary synchronous signals.
In other embodiments of the invention, before obtaining the cell conditions of each frequency, can determine first the RRC status of user terminal, namely determine to be in the RRC_IDLE state, still be in the RRC_CONNECTED state.When user terminal is in RRC_IDLE state lower time, carry out nearby region measurement according to priority and the user terminal current service cell signal strength signal intensity of adjacent area; When user terminal is in the RRC_CONNECTED state, carry out nearby region measurement according to network configuration and current service cell signal strength signal intensity.
Then, execution in step S20: the uplink-downlink configuration of obtaining each frequency.In the present embodiment, the uplink-downlink configuration of obtaining each frequency comprises: choose a strongest residential quarter of synchronizing signal in each frequency; Read system message MIB, the SIB1 of this residential quarter; The uplink-downlink configuration of carrying among the resolution system message SIB1.By choosing a strongest residential quarter of synchronizing signal in each frequency, can be easy to reading of information, and the information that reads has higher reliability.The uplink-downlink configuration of carrying among the SIB1 by resolution system message just can be known the uplink-downlink configuration form of this residential quarter, i.e. a kind of in the uplink-downlink configuration form 0～6.Be synchro system based on the TD-LTE system, the uplink-downlink configuration of its co-frequency cell is identical, therefore, has obtained the uplink-downlink configuration of the residential quarter that synchronizing signal is the strongest in each frequency, has namely known the uplink-downlink configuration on this frequency.
In other embodiments of the invention, the uplink-downlink configuration of obtaining each frequency also can specifically realize as follows: choose a strongest residential quarter of synchronizing signal in each frequency; Receive the data of a radio frames at the frequency of this residential quarter; Obtain the descending sub frame in this radio frames, to obtain the uplink-downlink configuration of this radio frames.When having known the descending sub frame in the radio frames, just know the uplink-downlink configuration form of this radio frames, namely know the uplink-downlink configuration form of this frequency, for example, obtaining subframe 0,4,5,9 is descending sub frame, and just the uplink-downlink configuration of this frequency is uplink-downlink configuration form 1 as can be known; And for example obtain subframe 0,3,4,5,6,7,8,9 and be descending sub frame, just the uplink-downlink configuration of this frequency is uplink-downlink configuration form 5 as can be known.Specifically, can be with reference to following table 2:
Table 2
Further, the descending sub frame that obtains in this radio frames specifically comprises: subframe 0,3,4,5,6,7,8,9 is done respectively RSRP and rssi measurement; Subframe 0,5 RSRP and rssi measurement as with reference to amount, are compared RSRP and the RSSI of 6 subframes of residue respectively, if the difference of the RSRP of certain subframe and RSSI and reference quantity is respectively less than threshold T with reference quantity
RSRPAnd T
RSSI, then this subframe is descending sub frame.At this, subframe 1 and subframe 2 are not done RSRP and rssi measurement, because in the uplink-downlink configuration form 0～6, subframe 1 is all special subframe, subframe 2 is all sub-frame of uplink.Because subframe 0 and subframe 5 are fixing descending sub frames, by RSRP and the rssi measurement of subframe 0 and subframe 5 are measured as reference, subframe 3,4,6,7,8,9 RSRP and RSRP and the rssi measurement of rssi measurement and subframe 0 and subframe 5 are compared, can obtain just whether subframe 3,4,6,7,8,9 is descending sub frame.For example, when needs judge whether subframe 3 is descending sub frame, the RSRP of subframe 3 and rssi measurement are compared with RSRP and the rssi measurement of subframe 0 and subframe 5 respectively, if the comparison value of the RSRP of the RSRP of subframe 3 and rssi measurement and subframe 0 and rssi measurement (being the absolute value of difference) is respectively less than threshold T
RSRPAnd T
RSSIAnd the RSRP of the RSRP of subframe 3 and rssi measurement and subframe 5 and the comparison value of rssi measurement are also respectively less than threshold T
RSRPAnd T
RSSI, think that then subframe 3 is descending sub frame.Whether in like manner, just can obtain subframe 4,6,7,8,9 is descending sub frame.In the present embodiment, threshold T
RSRPLess than or equal to 3dB, threshold T
RSSILess than or equal to 6dB, can know reliably thus whether subframe 4,6,7,8,9 is descending sub frame, certainly, threshold T
RSRPAlso can be slightly larger than 3dB, threshold T
RSSIAlso can be slightly larger than 6dB.
By this step, can specifically draw the uplink-downlink configuration of each frequency, consider that present TD-LTE supports at most the measurement of 9 frequencies, then just can obtain the uplink-downlink configuration of these 9 frequencies, for example, the uplink-downlink configuration that 4 frequencies are arranged is uplink-downlink configuration form 3; The uplink-downlink configuration that 5 frequencies are arranged is uplink-downlink configuration form 5.
Then, execution in step S30: according to the uplink-downlink configuration of each frequency, determine that each frequency is used for the descending sub frame of measuring.In the present embodiment, determine that the descending sub frame that each frequency be used for to be measured can specifically realize as follows: at the frequency of different uplink-downlink configuration, be preferably the few frequency of descending sub frame and determine descending sub frame to be measured; Be a frequency when selecting descending sub frame to be measured, the descending sub frame that is not used according to the preferential selection of sequencing.
Concrete, in uplink-downlink configuration form 0～6, determine in the following order: the uplink-downlink configuration form is 0 frequency; The uplink-downlink configuration form is 6 frequency; The uplink-downlink configuration form is 1 frequency; The uplink-downlink configuration form is 2 frequency; The uplink-downlink configuration form is 3 frequency; The uplink-downlink configuration form is 4 frequency; The uplink-downlink configuration form is 5 frequency.Considering in 10 subframes of uplink-downlink configuration form 2 and uplink-downlink configuration form 3 has 6 subframes to be configured to descending sub frame (but reference table 1), and when determining frequency, also can determine in the following order: the uplink-downlink configuration form is 0 frequency; The uplink-downlink configuration form is 6 frequency; The uplink-downlink configuration form is 1 frequency; The uplink-downlink configuration form is 3 frequency; The uplink-downlink configuration form is 2 frequency; The uplink-downlink configuration form is 4 frequency; The uplink-downlink configuration form is 5 frequency.
After determining frequency, determine again the employed descending sub frame of each frequency.
By execution in step S30, just can determine the employed descending sub frame of each frequency.For example, having drawn the uplink-downlink configuration that 4 frequencies are arranged in step S20 is uplink-downlink configuration form 3; The uplink-downlink configuration that 5 frequencies are arranged is uplink-downlink configuration form 5.Then, in this step, at first carry out: in the frequency of different uplink-downlink configuration, be preferably the few frequency of descending sub frame and determine descending sub frame to be measured.Because the descending sub frame of uplink-downlink configuration form 3 is less than the descending sub frame of uplink-downlink configuration form 5, determine preferentially that then the uplink-downlink configuration form is 4 frequencies of 3.Then carry out: be a frequency when selecting descending sub frame to be measured, the descending sub frame that is not used according to the preferential selection of sequencing.Then in the uplink-downlink configuration form 3, preferentially using subframe 0, then be subframe 5,6,7, is 4 frequencies of 3 by using subframe 0,5,6,7, just can satisfying the uplink-downlink configuration form.Then, determine that the uplink-downlink configuration form is 5 frequency, in a radio frames, the descending sub frame of uplink-downlink configuration form 5 is: 0,3,4,5,6,7,8,9, because subframe 0,5,6,7 has been that 4 frequencies of 3 take by the uplink-downlink configuration form, then 5 of uplink-downlink configuration form 5 frequencies can only take subframe 3,4,8,9, also lack a subframe, then can only be with the subframe 0 of another radio frames, with respect to this radio frames, also can think subframe 10, namely according to sequencing, come descending sub frame 9 first descending sub frame that is not used afterwards.Specifically, can be according to such as following table 3 choice for use descending sub frames.
Table 3
Consider that present TD-LTE supports at most the measurement of 9 frequencies, has only listed the situation of 9 frequencies in the table 3.For example, the uplink-downlink configuration form of 9 frequencies is 1, and the descending sub frame of then selecting is 0,4,5,9,10,14,15,19,20, and wherein, subframe 10 is the subframe 0 of next radio frames, and subframe 20 is the subframe 0 of next radio frames again.According to above table, those skilled in the art have the 10th frequency with Yi Zhiruo, and the uplink-downlink configuration form also is 1, then will use descending sub frame 24.
Method by measurement provided by the invention adjacent area, finishing a measurement of taking turns only needs 0 to 10 totally 11 frames, and if by prior art, the uplink-downlink configuration form that then is equivalent to 9 frequencies all is 0, need to use subframe 0,5,10,15,20,25,30,35,40, totally 41 frames.This shows, by the method for measurement provided by the invention adjacent area, reduced and finished one and take turns nearby region measurement duration, thereby can increase the time that terminal can be slept, reduce the power consumption of terminal.
In addition, in the prior art, a GAP duration is 6ms, remove frequency change-over time, time that can only empty 5ms measures, if therefore according to existing technology, can only measure a descending sub frame, finish on the frequency measurement to subframe 0 or subframe 5.And the method by measurement provided by the invention adjacent area, for known GAP configuration (cycle and the GAP OFFSET parameter that comprise GAP) and the adjacent area frequency of known uplink-downlink configuration, in the GAP window, selectively frequency is carried out arrangement on the Measuring Time point, can greatly improve the service efficiency of GAP.As above the adjacent area uplink-downlink configuration in the example can be 0,3,4,5,6,7,8,9 as the subframe of measuring, if GAP OFFSET is 1, then the window of a GAP is subframe 1 to 6, and the subframe that can measure is 3,4,5; If GAP OFFSET is 2, then the GAP window is subframe 2 to 7, can be 3,4,5,6 as the descending sub frame of measuring, the like, can find out, use the method for measurement provided by the invention adjacent area, can in a GAP window, finish the measurement of frequency as much as possible.The GAP parameter of concrete number view network configuration of measuring frequency and adjacent area uplink-downlink configuration and decide.
Step S40: receive the symbol that each frequency is used for the descending sub frame of measurement, carry out nearby region measurement.In this step, specifically receive the symbol of the descending sub frame that each frequency be used for to measure to finish nearby region measurement, namely finish RSRP and rssi measurement.Wherein, finishing RSRP and rssi measurement is prior art, and the application repeats no more this.
Consider that the measurement of different frequent points may use two adjacent subframes, for example in the precedent, subframe 3 and subframe 4 will be for the measurements of different frequencies, and radio-frequency devices needs the regular hour in the frequency conversion, is generally 100us～200us, therefore, in an embodiment of the present invention, can not receive whole symbols of a descending sub frame, for example, the descending sub frame of receive to be used for measuring is the symbol of latter two outer symbol, carries out nearby region measurement; Receive the symbol of a time slot of descending sub frame that is used for measurement and first symbol in another time slot, carry out nearby region measurement.Because latter two symbol of each subframe does not have reference signal, therefore receive be used for the descending sub frame measured the symbol of latter two outer symbol do not reduce reception to reference signal, thereby will not affect the measurement to the adjacent area.And by receiving for the symbol of a time slot of descending sub frame of measuring and first symbol in another time slot, can completely comprise three reference signals, also can compare accurately nearby region measurement.And reduce the reception of a symbol, and with the time of vacating about 70us, thus, can compensate the time spent in the frequency conversion, improve the reliability of nearby region measurement.

Concrete, after frequency point cell detection module 21 obtains the cell conditions of each frequency, with communication to uplink-downlink configuration detection module 22; Uplink-downlink configuration detection module 22 obtains the uplink-downlink configuration of each frequency, for example the uplink-downlink configuration form of frequency 1～4 is 3, the uplink-downlink configuration form of frequency 5～9 is 5, uplink-downlink configuration detection module 22 with the uplink-downlink configuration communication of this frequency to sub-frame configuration module 23; Sub-frame configuration module 23 is according to the uplink-downlink configuration of each frequency, determine that each frequency is used for the descending sub frame of measuring, for example, frequency 1～4 uses respectively subframe 0,5,6,7, frequency 5～9 uses respectively subframe 3,4,8,9, and sub-frame configuration module 23 uses communication to nearby region measurement module 24 this descending sub frame; Nearby region measurement module 24 receives the descending sub frame that each frequency is used for measurement, carries out nearby region measurement, namely finally finishes the measurement to the adjacent area.
