Embodiment
Below in conjunction with accompanying drawing method provided by the present invention is elaborated.Need to prove, in the situation that do not conflict, embodiment and the feature among the embodiment among the application can make up mutually.
Fig. 1 is that a kind of frequency band that may occur very much in future network covers signal.Its Mid Frequency 1 is that full frequency band (for example 10MHz among the figure) is as grand covering; Frequency range 2,3 is band segment (for example each 5MHz bandwidth among the figure), and overlapping with frequency range 1, covers as focus.Wireless terminal is current to be resided in the frequency range 1 corresponding residential quarter 1.Fig. 2 is the corresponding network topology signal of above-mentioned network.
If according to existing techniques in realizing, wireless terminal is normally sampled near 6 wireless resource blocks (RB) the center of housing estate frequency, as shown in Figure 1 when the measurement of carrying out current service cell and neighbor cell.Because Measurement bandwidth is narrow, terminal is inaccurate to the measurement result of Serving cell and neighbor cell; Application number is that 200880003630.7 patent discloses another kind of method, by the wireless base station to its Measurement bandwidth of terminal configuration, terminal is measured at the Measurement bandwidth of configuration, but this method also has certain limitation, because in fact, along with the movement of UE on the geographical position, in the center of housing estate position, do not need the measurement of large bandwidth, and in the cell edge position, the measurement of the little bandwidth of possibility is again inadequate.Further, because the measurement of large bandwidth can cause the power consumption of terminal to increase, and very few Measurement bandwidth may make that measurement result is inaccurate and the mobility decision-making that leads to errors causes call drop or pingpang handoff.
Can see that from defects the reason that goes wrong is that the Measurement bandwidth of terminal fixes the residential quarter that a base station covers.The method of terminal Measurement bandwidth during the present invention can be a kind of increases under wireless base-station control, suppose under initial condition terminal still with 6RB as Measurement bandwidth, the configuration by the wireless base station can make terminal increase its Measurement bandwidth, thereby addresses the above problem.
Preferred embodiment one
Fig. 3 illustrates the flow chart of the present embodiment.
Step 100 (preliminary step), the Measurement bandwidth in a broadband of wireless terminal configuration.
The value of this wide-band width measurement bandwidth must be greater than the Measurement bandwidth 6RB that gives tacit consent in the prior art.In principle, it is so long as any bandwidth of the integer multiple of usable radio resources piece (RB) is all possible.Yet, consider that the transmission bandwidth value of supporting in the present LTE agreement is following optional value: i.e. 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20MHz, remove the corresponding 6RB bandwidth of 1.4MHz, therefore, but the selected value of this wide-band width measurement bandwidth is in [15RB, 25RB, 50RB, 75RB, 100RB].
About the implication of wireless resource block (RB), and being defined in the 3GPP TS36.211 agreement of LTE wireless system transmission bandwidth is documented.
In preferred version further, wireless terminal can be set to the downstream transmission bandwidth (dl-bandwidth) of Serving cell the Measurement bandwidth in described broadband, or the parameter " permission Measurement bandwidth " that network in the prior art is configured (AllowedMeasBandwidth) is configured to the Measurement bandwidth in described broadband.
Step 101, wireless terminal is measured resident Serving cell as Measurement bandwidth periodically to be not less than 6RB.
In this step, wireless terminal measure to as if the mass value RSRQ (Reference Signal Received Quality) of Serving cell reference signal (comprising common pilot signal CRS, the physical layer signals such as channel status pilot signal CSI-RS, modulation reference signals DM-RS).
In the preferential situation, wireless terminal is also measured neighbor cell except Serving cell is measured, and the neighbor cell list that configures in the system message that the information of described neighbor cell is sent by the wireless base station provides.Comprise particularly: homogeneous frequency adjacent area, alien frequencies neighbor cell and different system neighbor cell.
Also need measurement result is offered the wireless base station with measurement report (Measurement report) in form for being in wireless terminal under the linking status.
Step 102, wireless base station send the instruction that increases Measurement bandwidth to wireless terminal;
Further, according to the difference of the residing state of wireless terminal, the wireless base station sends the instruction that increases Measurement bandwidth by different modes to it, particularly:
For the wireless terminal that is under link (RRC CONNECTED) state, the wireless base station is by resending radio link reconfiguration message (RRC Connection Reconfiguration) to wireless terminal, and notifies wireless terminal in the mode of the field of " increase Measurement bandwidth " shown in this message (Increase Measurement Bandwidth).
For the wireless terminal that is under free time (IDLE) state, the wireless base station is by broadcast transmission system message (SIB), and in the field of " increase Measurement bandwidth " shown in the system message, notifies wireless terminal.
Because the terminal that is under the linking status can report the wireless base station with measurement report constantly, the residing geographical position of wireless terminal can be judged according to the measurement report of receiving in the wireless base station, so the mode of this embodiment relatively is fit to be in the terminal of linking status.
For the terminal under the idle condition, its position can't be known in the wireless base station, the increase band wide instruction that sends may lack directive property, in case and base station transmission system message increase Measurement bandwidth, the wireless terminal in this residential quarter under all idle condition all can be received and be carried out.
Step 103, wireless terminal receives instruction, adjusts its Measurement bandwidth, and Serving cell (and neighbor cell) is measured.
Measurement bandwidth after the wireless terminal adjustment is not less than the wide-band width measurement bandwidth value that the wireless terminal described in the step 100 configures.
This step also comprises, terminal is upgraded measurement report, and measurement report is sent to the wireless base station.
Preferably, wireless terminal obtains under wide-band width measurement to represent this measurement result in " wide-band width measurement " shown in measurement report field.
Because the mobility strategy normally occurs in the cell edge area, therefore adopt the measurement than the broadband can obtain more accurate measurement result at cell edge; Thereby do not reduced valuable power consumption and do not increase Measurement bandwidth for the terminal of center of housing estate, adopted the method for this embodiment to reach balance between certainty of measurement and the power consumption.
Preferred embodiment two
The present embodiment can be thought to carry out the optimization that wide-band width measurement lacks the directive property problem to what mention in embodiment one method for wireless terminal under the idle condition, but also is applicable to be in simultaneously the wireless terminal under the linking status.
Because the position of wireless terminal in the residential quarter be mobile, may be in the center of residential quarter or may be in the edge of residential quarter in certain concrete moment.Wireless terminal itself can continue resident residential quarter is measured, and its measurement result has real-time, can be used for judging its residing geographical position of current time.Therefore the triggering that increases Measurement bandwidth can be judged that being placed on terminal inner carries out.
Step 200 (preliminary step), the Measurement bandwidth in a broadband of wireless terminal configuration;
In addition, the wireless base station will trigger the condition that increases Measurement bandwidth and send to wireless terminal; Perhaps wireless terminal also can preset in inside this condition.
Preferably, but the selected value of described wide-band width measurement bandwidth is in [15RB, 25RB, 50RB, 75RB, 100RB].In further preferred, wireless terminal can be set to larger Measurement bandwidth with the downstream transmission bandwidth (dl-bandwidth) of Serving cell, or the parameter " permission Measurement bandwidth " that network in the prior art is configured (AllowedMeasBandwidth) is configured to the wide-band width measurement bandwidth.
Further, the wireless base station can define the condition that described triggering increases Measurement bandwidth by an event, for example:
Event X1, the RSRP value of current service cell is lower than certain threshold value
Event X2, the RSRQ value of current service cell is lower than certain threshold value
Event X3, the RSRP value of current service cell is higher than the RSRP value of neighbor cell with certain bias
During Project Realization, trigger condition can be or its combination in any in the above-mentioned event.
Further, a timer value TTT (Time To Trigger) expression trigger condition can also be defined and the increase that just can really trigger Measurement bandwidth must be in this timer, satisfied all the time.
Because RSRP or RSRQ are intuitively reflecting the signal strength signal intensity that comes from Serving cell that wireless terminal receives; Generally speaking, UE is nearer apart from the base station, and its received signal strength signal intensity is larger, and quality is better, and therefore above-mentioned event is in secret is representing terminal in the positional information of current service cell.
Step 201, wireless terminal is measured resident Serving cell as Measurement bandwidth periodically to be not less than 6RB.
Wireless terminal measure to as if performance number RSRP (Reference Signal Received Power) and the mass value RSRQ (Reference Signal Received Quality) of Serving cell reference signal (comprising the physical layer signals such as CRS, CSI-RS, DM-RS).
In the preferential situation, wireless terminal is also measured neighbor cell except Serving cell is measured, and the neighbor cell list that configures in the system message that the information of described neighbor cell is sent by the wireless base station provides.Comprise particularly: homogeneous frequency adjacent area, alien frequencies neighbor cell and different system neighbor cell.
Step 202, wireless terminal carries out condition judgment according to real-time measurement result, if condition satisfies then adjusts its Measurement bandwidth.
Preferably, described condition is one of condition described in the step 200 or combination in any.If dispose the TTT timer, then must in timer time, satisfy condition all the time and just can adjust.Because the time variation of wireless environment, the benefit that increases timer is to overcome the uncertainty that instantaneous channel variation is brought, and the credibility of adjustment improves.
Measurement bandwidth after the wireless terminal adjustment is not less than the wide-band width measurement bandwidth of the wireless terminal configuration described in the step 200.
Step 203, wireless terminal is measured Serving cell (and neighbor cell) to adjust rear Measurement bandwidth.
This step also comprises, terminal is upgraded measurement report, and measurement report is sent to the wireless base station.
Preferably, wireless terminal obtains under wide-band width measurement to represent this measurement result in " wide-band width measurement " shown in measurement report field.
The below is described wireless terminal provided by the present invention.
The embodiment of the invention is improved wireless terminal, this wireless terminal is when measuring at least one Radio Link in its Serving cell and the neighbor cell, can increase Measurement bandwidth, thereby can overcome the defective that the single-measurement bandwidth is brought in the correlation technique, adjust Measurement bandwidth according to necessary scene, reach the balance between certainty of measurement and the electric quantity consumption.
