The present invention also provides a kind of preferred implementation, and namely terminal comprises according to frequency and system bandwidth calculating measurement bandwidth: determine that system bandwidth is as measuring bandwidth.In this preferred implementation, the system bandwidth that terminal directly issues the base station is carried out the measurement of reference signal as measuring bandwidth, saved like this and calculated the step of measuring bandwidth, considered situation about only need simply measure sometimes, this optimal way can be met the measurement result of requirement.
Terminal also needs whole measurement bandwidth is sampled when measuring reference signals, so terminal comprises according to measuring the bandwidth measurement reference signal: terminal is sampled to continuous wireless resource block on whole measurement bandwidth; Terminal is according to the wireless resource block measuring reference signals of sampling.Sampled point covers whole measurement bandwidth, thereby guaranteed to measure the RST that can reflect all sidedly on the frequency range, but terminal need not all will carry out sampled measurements to each RB that measures on the bandwidth, thereby has reduced the workload of terminal sampled measurements, has saved energy consumption.
Terminal is measured each frequency and is finished in must be at a fixed time, generally can be set to 480ms or 240ms.So terminal comprises according to measuring the bandwidth measurement reference signal: terminal is to each frequency measuring reference signals in predefined Measuring Time.In this preferred embodiment, the identical Measuring Time of all frequency regulations is helped to control total Measuring Time, in time obtain whole measurement result, and in time make the mobility decision-making.
Preferably, terminal to each frequency in predefined Measuring Time after the measuring reference signals, also comprise: terminal generates measurement report according to measurement result; Terminal is to high-rise reporting measurement reports, and carries out the measurement of following one-period according to predefined Measuring Time, and wherein, the described cycle is that described predefined Measuring Time multiply by frequency points.Be example with 480ms, if the frequency number that the base station issues to terminal is N (comprises with point and alien frequencies frequency) again and again, to finish the time cycle of measurement be N*480ms to terminal so.
Need to prove that under the situation of right and wrong LTE residential quarter, residential quarter, terminal is determined the system bandwidth of residential quarter according to the system under the residential quarter.For the LTE residential quarter, terminal can be utilized the measurement bandwidth measurement reference signal that disposes in the method shown in Figure 1; For non-LTE residential quarter, the base station does not need to send corresponding measurement bandwidth or system bandwidth, because the bandwidth of the wireless standard of non-LTE system is all fixed, bandwidth such as the UMTS system is 3.84MHz, the bandwidth of TD system is 1.28MHz etc., so terminal can be determined its system bandwidth according to the system under it.
By above-described embodiment as can be known, the measurement bandwidth of terminal of the present invention can flexible configuration, or measures bandwidth length for some cell extension, thereby obtains more accurate measurement result, for the mobility decision-making provides more believable foundation; When this flexible configuration is when being controlled by network side, the base station can dispose optimal measurement bandwidth according to different network design scenes, makes the measurement of terminal reach accuracy of measurement and measures optimum balance between the power consumption.
Be described in detail below in conjunction with the implementation procedure of example to the embodiment of the invention.
The measuring object of terminal is the reference signal of residential quarter in the following preferred embodiment, specifically comprises the reference signal of the neighbor cell that disposes in the current persistent district of terminal and the system message; Particularly, that measure is reference signal strength (Reference Signal Received Power, abbreviate RSRP as) or reference signal quality (Reference Signal Received Quality, abbreviate RSRQ as), method of the present invention all is same being suitable for for measure R SRP and RSRQ, but be example with measure R SRQ in the preferred embodiment below for convenience.
Preferred embodiment one
Fig. 3 is the flow chart according to the reference signal method of measurement of the preferred embodiment of the present invention one, as shown in Figure 3, measure in network configuration under the condition of bandwidth, terminal is carried out the RSRQ measurement according to the measurement bandwidth of configuration, comprises that specifically following step S302 is to step S304.
Step S302, the base station is according to concrete network design allocating and measuring bandwidth, and is issued to terminal.
Particularly, the base station at first needs the measurement frequency of configurating terminal, comprises with frequency frequently and the frequency of alien frequencies, and correspondingly, the measurement bandwidth of base station configuration also comprises common frequency measurement bandwidth and different-frequency measure bandwidth.So-called with frequently and alien frequencies be that frequency with residential quarter, place, base station is reference, identical be frequently same, different is alien frequencies.Because the concrete deployment scenario of each residential quarter is understood very much by the operator of network, therefore the measurement bandwidth by the network side configurating terminal can use the known information of network, each concrete residential quarter is arranged optimum measurement bandwidth value, and the configuration of different districts can flexible transformation, when guaranteeing to measure order of accuarcy, reduced the unnecessary measurement of terminal again, reached accuracy and measure the balance of power consumption.
Below in conjunction with two examples measurement band width configuration under the concrete network design is described.
Fig. 4 is the bandwidth schematic diagram according to the concrete network design of the preferred embodiment of the present invention one, and as shown in Figure 4, the system bandwidth of cell1 is BW1, and the system bandwidth of cell2 is BW2, and the system bandwidth of cell3 is BW3.When the base station disposes, namely be their system bandwidth for their measurement bandwidth of cell1 and cell3 configuration, though be BW2 for its system bandwidth of cell2, but the band overlapping of it and cell1 partly is BW2 ', in order truly to reflect useful signal that terminal is subjected to and the situation of interference when cell2 is resident, only need the RSRQ that measures on the BW2 ' to get final product, so the measurement bandwidth of base station configuration cell2 is BW2 '.
When concrete configuration, the base station is to carry out with the configuration of frequency and pilot frequency point according to the current resident residential quarter of terminal.Such as the current cell1 that resides in of terminal, so the base station just configuration with some F1 again and again with the measurement bandwidth BW 1 of frequency, and the measurement bandwidth BW 2 ' of pilot frequency point F2, F3 and corresponding pilot frequency point and BW3 (F1, F2, F3 are respectively the center frequency point of cell1, cell2, cell3 here).
Fig. 5 is the bandwidth schematic diagram according to the another kind of concrete network design of the preferred embodiment of the present invention one, shown in Figure 5 and difference Fig. 4 be on the frequency band of cell3, also the to have superposeed frequency band of cell4, obviously, best, the base station is set to BW4 to the measurement bandwidth of cell4, but because the frequency of cell4 and the frequency of cell3 all are F3, and measure bandwidth and depend on frequency, so the base station still is BW3 for the measurement bandwidth of pilot frequency point F3 configuration.
Just will measure bandwidth information after base station allocating and measuring bandwidth is finished and be handed down to terminal together with frequency.
Specifically, the measurement bandwidth with frequency is going up transmission with frequency System information block (System Information Block abbreviates SIB3 as); The measurement bandwidth of pilot frequency point sends at alien frequencies System information block (SIB5).
Under the more excellent situation, the base station is when issuing frequency and measuring bandwidth, and also the system bandwidth with the current persistent district of terminal together issues.Still be example with top Fig. 5, if terminal resides among the cell4 at this moment, terminal can together be handed down to the system bandwidth BW4 of cell4 in the base station so.
In the Project Realization, the system bandwidth of persistent district can be placed on and broadcast all terminals that are handed down to this residential quarter in the main information unit (MIB).
Step S304, terminal is carried out RSRQ accordingly and is measured after receiving the frequency that network issues and measuring bandwidth.
Particularly, the measurement of terminal also is to carry out according to frequency and corresponding measurement bandwidth.Here need explanation, the bandwidth of LTE system is tolerance with the RB number, RB is bandwidth unit minimum in the LTE system, also is that terminal is implemented a concrete sampled point of measuring among the present invention, and concrete sampled measurements refers to that terminal measures the RSRQ value on certain RB.
The measurement of terminal must be covered corresponding all the measurement bandwidth of frequency (with frequency or pilot frequency point), but concrete sample mode can be flexibly.Be the concrete sample mode that a kind of terminal is measured as shown in Figure 6, terminal is to some groups of continuous RB sampled measurements, the vacant RB of interval some between group and the group.Be another kind of concrete sample mode as shown in Figure 7, measure bandwidth and be divided into several littler measuring units, terminal on each measuring unit at random choose several RB sampled measurements, sampling can be discrete, as first sampling unit; Also can be continuous, as second sampling unit.
In a word, terminal has multiple concrete way of realization to sample, sampled point covers whole measurement bandwidth, thereby guaranteed to measure the RST that can reflect all sidedly on the described frequency range, but this does not also mean that terminal must all will carry out sampled measurements to each RB that measures on the bandwidth, thereby reduced the workload of terminal sampled measurements, saved energy consumption.
For the preferential situation described in the step S302, if terminal also has been handed down to the system bandwidth of the current persistent district of terminal in the base station, terminal also can be carried out measurement as measuring bandwidth to current persistent district or with frequency with the system bandwidth of persistent district so, the concrete mode of measuring can be flexibly with top identical.
The measuring process of terminal from another perspective, terminal are measured each frequency and are finished in must be at a fixed time, generally can be set to 480ms or 240ms.So, give the flexibility of the concrete sampling of terminal, also give terminal from another point of view and adjusted the space of different sampling policies for the measurement bandwidth of different frequent points, can both in official hour, finish measurement to guarantee it.
The identical Measuring Time of all frequency regulations is helped to control total Measuring Time, in time obtain whole measurement result, and in time make the mobility decision-making.Be example with top 480ms, if the frequency number that the base station issues to terminal is N (comprises with point and alien frequencies frequency) again and again, to finish the time cycle of measurement be N*480ms to terminal so.
Terminal must be finished all measurements on the expiration of this period, and generates measurement report and report high level, begins next measuring period then.
Specifically, terminal is to carry out with the form of trigger event to high-rise reporting measurement reports, surpass certain thresholding such as the RSRQ value of measuring, or the RSRQ of two residential quarters is when having surpassed adjustings such as thresholding and having satisfied, trigger certain trigger event and report high level, and in measurement report, carry concrete measurement result.High level decides the mobility strategy or reports the base station according to composition of matter and concrete RSRQ value afterwards.These there is no different with prior art.
Preferred embodiment two
Fig. 8 is the flow chart according to the reference signal method of measurement of the preferred embodiment of the present invention two, as shown in Figure 8, comprises that following step S802 is at step S804.
Step S802, the network configuration system bandwidth, and be handed down to terminal.
Step S804, terminal is measured according to the system bandwidth of configuration.
Different with above preferred embodiment one is the measurement bandwidth that the base station does not dispose each frequency, but the system bandwidth of each frequency is issued to terminal.With reference to the network scenarios of figure 4, that network side issues is frequency F1, F2, F3 and its corresponding bandwidth BW 1, BW2, BW3.
Terminal has two kinds of selections after receiving frequency that network issues and system bandwidth information:
(1) terminal is measured as measuring bandwidth with system bandwidth simply; Perhaps
(2) terminal calculates the measurement bandwidth according to the system bandwidth oneself of frequency and each frequency, and measures with the measurement bandwidth that this calculates.
Still be example with Fig. 4, F1, BW1 and F2, BW2 are known for terminal, so terminal can calculate the overlapping bands BW2 ' of cell1 and cell2, with this measurement bandwidth as F2.And for the deployment scenario among Fig. 5, terminal is under the situation of known F3, BW3, BW4, can calculate the overlapping bands part of cell1 and cell3, also can calculate cell1, cell3, the common lap of cell4, and terminal can be set the measurement bandwidth of F3 according to the needs of self, BW3 or BW4.The benefit of aforesaid way be give further the terminal flexibility ratio in conjunction with s own situation the setting measurement bandwidth.
Terminal is after having determined the measurement bandwidth, and the concrete sampling of execution, measuring process and preferred embodiment one are identical, repeat no more herein.
Preferred embodiment three
Fig. 9 is the schematic diagram of disposing according to the heterogeneous network of the preferred embodiment of the present invention three, as shown in Figure 9, cell1 is the LTE residential quarter and is the current persistent district of terminal, frequency is F1, and bandwidth is BW1, and cell3 is that the UMTS residential quarter (also can be the GSM residential quarter, TD-SCDMA residential quarter etc., only need right and wrong LTE residential quarter), frequency is F3, bandwidth is BW3.
Under this network design, still can measure with the mode in above preferred embodiment one or the preferred embodiment two for cell1, but for cell3, the base station does not need to send corresponding measurement bandwidth or system bandwidth, because the bandwidth of the wireless standard of non-LTE system is all fixed, such as being 3.84MHz for UMTS, TD is 1.28MHz etc., so terminal can be determined its system bandwidth according to the system under it.
Preferred embodiment four
This preferred embodiment can be regarded the further optimization of preferred embodiment one as, the measurement bandwidth minimum of network configuration is 6RB, and when the measurement bandwidth of network configuration is 6RB, terminal can respectively be expanded several RB at the two ends up and down of this 6RB bandwidth, as the measurement bandwidth that increases, and implement to measure.
Because 6RB is a very little bandwidth, if may cause the error of measurement excessive inadequately with this owing to sample as measuring bandwidth, give terminal level of freedom increase measurement sample and can under the prerequisite that terminal power allows, obtain measurement result more accurately.
Need to prove, can in the computer system such as one group of computer executable instructions, carry out in the step shown in the flow chart of accompanying drawing, and, though there is shown logical order in flow process, but in some cases, can carry out step shown or that describe with the order that is different from herein.
