Description
Technical field
The present invention relates to mobile communication technology field, particularly a kind of method and user terminal measuring adjacent area.
Background technology
In mobile communication system, along with the movement of mobile subscriber, the user terminal (User Equipment, UE) that this mobile subscriber uses may move to the coverage of another community from the coverage of current service cell.When the radio signal quality of UE Serving cell is poor, usually need UE 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 needs the frequency Received signal strength in relevant adjacent area, and measure the radio signal quality of adjacent area, the Target cell for the treatment of gravity treatment is decided by UE under RRC_IDLE state, under 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 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, Long Term Evolution plan) in provide the idle window (GAP) of a kind of measurement for carrying out different-frequency measure under RRC_CONNECTED state, cycle occurs GAP in time, and the cycle divides 40ms and 80ms two kinds, and the duration is 6ms.
In LTE system, measuring amount under RRC_CONNECTED state can be Reference Signal Received Power (the Reference Signal Received Power of community, RSRP), on the Measurement bandwidth of place, the Shi Gai community frequency that RSRP measures, carry the linear power mean value of the physical resource unit (Resource Element) of " the specific reference signal in community (the Cell-specific Reference Signal; CRS) " of this community, unit is dBm.Measuring amount under RRC_CONNECTED state can also be Reference Signal Received Quality (the Reference Signal Received Quality of community, RSRQ), RSRQ needs the RSRP and received signal strength indicator (the Received Signal Strength Indicator that measure community, RSSI), wherein, on the Measurement bandwidth of place, the Shi Gai community frequency of rssi measurement, the total received power of all Physical Resource Block (Resource Block), comprise the power of people having a common goal (Co-Channel) Serving cell and adjacent cell, neighboring trace (Adjacent Channel) disturbs, thermal noise etc.RSRQ is defined as (N × RSRP/RSSI), and unit is dB, and wherein, N represents the Physical Resource Block number on the Measurement bandwidth of this place, community frequency.
Need to use the descending sub frame in LTE system to the measurement of above-mentioned measuring amount.TD-LTE is the one 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, and 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 and is made up of 6 or 7 symbols (OFDM symbol), 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), is to use this descending sub frame to measure in TD-LTE system, and conventional sub-frame configuration scheme is as following table 1:
Table 1
Wherein, D represents descending sub frame, and U represents up substation, and S represents special subframe.
For TD-LTE system, above-mentioned 7 kinds of configurations can be used to carry out the uplink-downlink configuration of flexibility and changeability, and alien frequencies adjacent area can use different uplink-downlink configuration.In various uplink-downlink configuration form, what be fixed as descending sub frame only has subframe 0 and subframe 5.Therefore, in the prior art, can only by measuring subframe 0 and subframe 5 in the duration of GAP, and the duration of a GAP is 6ms, remove frequency switch on consuming time, substantially only having 5.5ms for measuring, thus can only the adjacent area on a frequency to be measured, thus, make the utilance of GAP not high.In addition, because a GAP can only measure the adjacent area on a frequency, cause a wheel measurement duration long, thus decreased the time that terminal can sleep, add the power consumption of terminal.

Embodiment
Below in conjunction with the drawings and specific embodiments, the method for measurement adjacent area provided by the invention and user terminal are described in further detail.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 the form simplified very much, only in order to object that is convenient, the aid illustration embodiment of the present invention lucidly.
Embodiment one
Please refer to Fig. 1, it is the schematic flow sheet of the method for the measurement adjacent area of the embodiment of the present invention one.As shown in Figure 1, the method measuring adjacent area in the present embodiment specifically comprises the steps:
First, step S10 is performed: the cell conditions obtaining each frequency.In the present embodiment, the cell conditions of each frequency comprises: the community number of each frequency, the ID of each community and timing information.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 auxiliary synchronous signals.
In other embodiments of the invention, before the cell conditions obtaining each frequency, first can determine the RRC status of user terminal, namely determine to be in RRC_IDLE state, be still in RRC_CONNECTED state.When user terminal is under RRC_IDLE state, carry out nearby region measurement according to the priority of adjacent area and user terminal current service cell signal strength signal intensity; When user terminal is in RRC_CONNECTED state, carry out nearby region measurement according to network configuration and current service cell signal strength signal intensity.
Then, step S20 is performed: the uplink-downlink configuration obtaining each frequency.In the present embodiment, the uplink-downlink configuration obtaining each frequency comprises: choose the community that synchronizing signal in each frequency is the strongest; Read the system message MIB of this community, SIB1; The uplink-downlink configuration of carrying in resolution system message SIB1.By choosing a strongest community of synchronizing signal in each frequency, the reading of information can be easy to, and the information read has higher reliability.The uplink-downlink configuration of carrying in the SIB1 by resolution system message just can know the uplink-downlink configuration form of this community, the one namely in uplink-downlink configuration form 0 ~ 6.Be synchro system based on TD-LTE system, the uplink-downlink configuration of its co-frequency cell is identical, therefore, obtains the uplink-downlink configuration of the community 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 obtaining each frequency also can realize especially by following steps: choose the community that synchronizing signal in each frequency is the strongest; The frequency of this community receives the data of a radio frames; Obtain the descending sub frame in this radio frames, to obtain the uplink-downlink configuration of this radio frames.When being aware of the descending sub frame in radio frames, just can know the uplink-downlink configuration form of this radio frames, namely know the uplink-downlink configuration form of this frequency, such as, obtaining subframe 0,4,5,9 is descending sub frame, and just the uplink-downlink configuration of this frequency known is uplink-downlink configuration form 1; And for example obtaining subframe 0,3,4,5,6,7,8,9 is descending sub frame, and just the uplink-downlink configuration of this frequency known is uplink-downlink configuration form 5.Specifically, can with reference to following table 2:
Table 2
Further, the descending sub frame obtained in this radio frames specifically comprises: do RSRP and rssi measurement respectively to subframe 0,3,4,5,6,7,8,9; The RSRP of subframe 0,5 and rssi measurement are measured as reference, RSRP and RSSI of residue 6 subframes is compared with reference quantity respectively, if the difference of RSRP and RSSI of certain subframe and reference quantity is less than threshold T respectively
rSRPand T
rSSI, then this subframe is descending sub frame.At this, RSRP and rssi measurement are not done to subframe 1 and subframe 2, because in uplink-downlink configuration form 0 ~ 6, subframe 1 is all special subframe, and subframe 2 is all sub-frame of uplink.Because subframe 0 and subframe 5 are fixing descending sub frames, by the RSRP of subframe 0 and subframe 5 and rssi measurement are measured as reference, the RSRP of subframe 3,4,6,7,8, the 9 and RSRP of rssi measurement and subframe 0 and subframe 5 and rssi measurement are compared, just can obtain whether subframe 3,4,6,7,8,9 is descending sub frame.Such as, when needs judge whether subframe 3 is descending sub frame, the RSRP of subframe 3 and rssi measurement are compared, if the comparison value of the RSRP of the RSRP of subframe 3 and rssi measurement and subframe 0 and rssi measurement (i.e. the absolute value of difference) is less than threshold T respectively with the RSRP of subframe 0 and subframe 5 and rssi measurement respectively
rSRPand T
rSSI; And the RSRP of the RSRP of subframe 3 and rssi measurement and subframe 5 and the comparison value of rssi measurement are also less than threshold T respectively
rSRPand T
rSSI, then think that subframe 3 is for descending sub frame.In like manner, just can obtain whether subframe 4,6,7,8,9 is descending sub frame.In the present embodiment, threshold T
rSRPbe less than or equal to 3dB, threshold T
rSSIbe less than or equal to 6dB, reliably can know whether subframe 4,6,7,8,9 is descending sub frame thus, certainly, threshold T
rSRPalso can slightly larger than 3dB, threshold T
rSSIalso can slightly larger than 6dB.
By this step, specifically can draw the uplink-downlink configuration of each frequency, consider that current TD-LTE supports at most the measurement of 9 frequencies, then just can obtain the uplink-downlink configuration of these 9 frequencies such as, have the uplink-downlink configuration of 4 frequencies to be uplink-downlink configuration form 3; The uplink-downlink configuration of 5 frequencies is had to be uplink-downlink configuration form 5.
Then, step S30 is performed: according to the uplink-downlink configuration of each frequency, determine the descending sub frame of each frequency for measuring.In the present embodiment, determine that each frequency can realize especially by following steps for the descending sub frame measured: 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; When selecting descending sub frame to be measured for a frequency, according to sequencing prioritizing selection not by the descending sub frame used.
Concrete, in uplink-downlink configuration form 0 ~ 6, determine in the following order: uplink-downlink configuration form is the frequency of 0; Uplink-downlink configuration form is the frequency of 6; Uplink-downlink configuration form is the frequency of 1; Uplink-downlink configuration form is the frequency of 2; Uplink-downlink configuration form is the frequency of 3; Uplink-downlink configuration form is the frequency of 4; Uplink-downlink configuration form is the frequency of 5.Considering in uplink-downlink configuration form 2 and 10 subframes of uplink-downlink configuration form 3 and have 6 subframes to be configured to descending sub frame (can reference table 1), when determining frequency, also can determine in the following order: uplink-downlink configuration form is the frequency of 0; Uplink-downlink configuration form is the frequency of 6; Uplink-downlink configuration form is the frequency of 1; Uplink-downlink configuration form is the frequency of 3; Uplink-downlink configuration form is the frequency of 2; Uplink-downlink configuration form is the frequency of 4; Uplink-downlink configuration form is the frequency of 5.
After determining frequency, then determine the descending sub frame that each frequency uses.
By performing step S30, the descending sub frame that each frequency uses just can be determined.Such as, in step S20, drawn have the uplink-downlink configuration of 4 frequencies to be uplink-downlink configuration form 3; The uplink-downlink configuration of 5 frequencies is had to be uplink-downlink configuration form 5.Then, in this step, first perform: 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.Descending sub frame due to uplink-downlink configuration form 3 is less than the descending sub frame of uplink-downlink configuration form 5, then preferentially determine that uplink-downlink configuration form is 4 frequencies of 3.Then perform: when selecting descending sub frame to be measured for a frequency, according to sequencing prioritizing selection not by the descending sub frame used.Then in uplink-downlink configuration form 3, preferential use subframe 0, then be subframe 5,6,7, by use subframe 0,5,6,7, just can meet 4 frequencies that uplink-downlink configuration form is 3.Then, determine that uplink-downlink configuration form is the frequency of 5, in a radio frame, the descending sub frame of uplink-downlink configuration form 5 is: 0, 3, 4, 5, 6, 7, 8, 9, due to subframe 0, 5, 6, 7 has been 3 by uplink-downlink configuration form, and 4 frequencies take, then 5 frequencies of uplink-downlink configuration form 5 can only take subframe 3, 4, 8, 9, also lack a subframe, then can only by the subframe 0 of another radio frames, relative to this radio frames, also subframe 10 can be thought, namely according to sequencing, come after descending sub frame 9 first not by the descending sub frame used.Specifically, can according to such as following table 3 choice for use descending sub frame.
Table 3
Consider that current TD-LTE supports at most the measurement of 9 frequencies, in table 3, only list the situation of 9 frequencies.Such as, the uplink-downlink configuration form of 9 frequencies is 1, then the descending sub frame selected 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, Yi Zhiruo is had the 10th frequency by those skilled in the art, and uplink-downlink configuration form is also 1, then will use descending sub frame 24.
By the method for measurement adjacent area provided by the invention, complete a measurement taken turns and only need 0 to 10 totally 11 frames, and if by prior art, then the uplink-downlink configuration form being equivalent to 9 frequencies is all 0, need to use subframe 0,5,10,15,20,25,30,35,40, totally 41 frames.As can be seen here, by the method for measurement adjacent area provided by the invention, decrease one and taken turns nearby region measurement duration, thus the time that terminal can sleep can have been increased, reduced the power consumption of terminal.
In addition, in prior art, a GAP duration is 6ms, removing frequency change-over time, can only measure, if therefore according to existing technology time of empty 5ms, can only measure a descending sub frame, complete the measurement to subframe 0 or subframe 5 on a frequency.And by the method for measurement adjacent area provided by the invention, known GAP is configured to the adjacent area frequency of (comprising cycle and the GAP OFFSET parameter of GAP) and known uplink-downlink configuration, in GAP window, selectively frequency is carried out to the arrangement on Measuring Time point, greatly can improve the service efficiency of GAP.As above the adjacent area uplink-downlink configuration in example, the subframe that can be used as to measure is 0,3,4,5,6,7,8,9, if GAP OFFSET is 1, then the window of a GAP is subframe 1 to 6, and the subframe can carrying out measuring is 3,4,5; If GAP OFFSET is 2, then GAP window is subframe 2 to 7, and the descending sub frame that can be used as to measure is 3,4,5,6, the like, can find out, use the method for measurement adjacent area provided by the invention, the measurement of frequency as much as possible can be completed in a GAP window.The number of concrete measurement frequency is depending on the GAP parameter of network configuration and adjacent area uplink-downlink configuration.
Step S40: receive each frequency for the symbol in the descending sub frame measured, carry out nearby region measurement.In this step, concrete receive each frequency for the symbol in the descending sub frame measured to complete nearby region measurement, namely complete RSRP and rssi measurement.Wherein, complete RSRP and rssi measurement is prior art, the application repeats no more this.
Consider that the measurement of different frequent points may use two adjacent subframes, such as, in precedent, subframe 3 and subframe 4 will be used for the measurement of different frequencies, and radio-frequency devices needs the regular hour in frequency conversion, is generally 100us ~ 200us, therefore, in an embodiment of the present invention, whole symbols of a descending sub frame can not be received, such as, receive the symbol for latter two outer symbol in the descending sub frame measured, carry out nearby region measurement; Receiving the symbol of a time slot in the descending sub frame for measuring and first symbol in another time slot, carrying out nearby region measurement.Because latter two symbol of each subframe does not have reference signal, the symbol therefore receiving latter two outer symbol in the descending sub frame for measuring does not reduce the reception to reference signal, thus the measurement that will do not affect adjacent area.And pass through to receive the symbol of a time slot in the descending sub frame for measuring and first symbol in another time slot, complete packet three reference signals can be contained, also accurately nearby region measurement can be compared.And reduce the reception of a symbol, will the time of about 70us be vacated, thus, the used time in frequency conversion can be compensated, improve the reliability of nearby region measurement.

Concrete, after frequency point cell detection module 21 obtains the cell conditions of each frequency, by information transmission to uplink-downlink configuration detection module 22; Uplink-downlink configuration detection module 22 obtains the uplink-downlink configuration of each frequency, the uplink-downlink configuration form of such as frequency 1 ~ 4 is 3, the uplink-downlink configuration form of frequency 5 ~ 9 is 5, uplink-downlink configuration detection module 22 by the uplink-downlink configuration information transmission 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 the descending sub frame of each frequency for measuring, such as, frequency 1 ~ 4 uses subframe 0,5,6,7 respectively, frequency 5 ~ 9 uses subframe 3,4,8,9 respectively, and this descending sub frame uses information transmission to nearby region measurement module 24 by sub-frame configuration module 23; Nearby region measurement module 24 receives the descending sub frame of each frequency for measuring, and carries out nearby region measurement, namely finally completes the measurement to adjacent area.
