Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of measurement collocation method, system and equipment of multicarrier system.
Background technology
LTE (Long Term Evolution, Long Term Evolution) is 3G (3rd Generation, third generation digital communication) evolution, LTE improves and has strengthened the aerial access technology of 3G, adopt OFDM (Orthogonal Frequency Division Multiplexing, OFDM) and MIMO (Multiple Input Multiple Output, multiple-input and multiple-output) as the standard of this LTE wireless network evolution.Wherein, the LTE system and before wireless communication system in, have only a carrier wave in the sub-district, as shown in Figure 1, the maximum bandwidth in the LTE system is 20MHz; And under the spectral bandwidth of 20MHz, LTE can provide the peak rate of descending 100Mbit/s and up 50Mbit/s, improves the performance of Cell Edge User, and improves cell capacity and reduce system delay.In addition, in the LTE system, UE (User Equipment, subscriber equipment) can only work under a carrier wave simultaneously, and a LTE sub-district has only a carrier wave, and each LTE sub-district is identified by a number unique in network.The UE synchronization can only carry out data transmit-receive in a sub-district, this sub-district is also referred to as the Serving cell of UE.
And increasing rapidly along with the number of users of mobile terminal amount, terminal use's volume of business is exponential increase, in order to satisfy the terminal use's who continues to increase business demand, the business and the needed more peak value speed of application that need provide bigger bandwidth to satisfy the terminal use.In LTE-A (LTE-Advanced, senior LTE) system, the peak rate of system has huge raising than LTE, requirement reaches descending 1Gbps, up 500Mbps, at this moment, if only use the carrier wave of a maximum bandwidth, obviously be the requirement that can't reach peak rate as 20MHz.Therefore, the LTE-A system needs the operable bandwidth of terminal extension user, introduced CA (Carrier Aggregation thus, carrier aggregation) technology, be about to a plurality of continuous or discrete carrier aggregation (between sub-district under the different e NB or the member carrier can not polymerization) together under the same eNB (or base station), simultaneously for the UE service, so that UE to be provided required speed.Wherein, the above-mentioned carrier wave that condenses together is called CC (Component Carrier, member carrier) again.

In the prior art, when the UE of LTE system was operated on the single carrier, network side can measure start thresholding (S-measure) for UE dispose one, if when the channel quality of UE Serving cell is lower than this S-measure, then UE starts the measuring process of configuration; And if network side is measured configuration to UE S-measure is not provided the time, then UE receive measure configuration after, start corresponding measuring process according to configuration information.As can be seen, when network side had disposed S-measure, then S-measure was the thresholding whether UE starts measurement.
In realizing process of the present invention, the inventor finds to exist at least in the prior art following shortcoming:
Current measurement is disposed employed measurement startup thresholding all at UE, and promptly each UE only has one to measure startup thresholding S-measure, thereby makes startup and the pass closed procedure measured to carry out at UE.And,, can't carry out the opening and closing of measurement of correlation to a plurality of carrier waves of UE separately in the prior art because UE can be operated on a plurality of carrier waves in polymerization for the multicarrier system of LTE-A.

The embodiment of the invention three provides a kind of measurement collocation method of multicarrier system, and this method is at the multicarrier system of LTE-A, and certainly, in the practical application, the measurement collocation method of this multicarrier system also can be applied to other multicarrier systems.As shown in Figure 5, this method may further comprise the steps:
Concrete, network equipment be the multicarrier allocating and measuring of the UE mode that starts thresholding including but not limited to:
Network equipment disposes separately independently S-measure for each member carrier; Perhaps,
Network equipment is each member carrier configuration set S-measure independently separately; Perhaps,
Network equipment is the unified S-measure of all member carrier configurations.
Certainly, in actual applications, be not limited to the mode that above-mentioned allocating and measuring starts thresholding, network equipment can select allocating and measuring to start the mode of thresholding according to actual needs.For example, network equipment is a plurality of member carrier configuration S-measure 1 in all member carriers, and is other member carrier configurations S-measure 2.
Need to prove, prescribe a time limit at the multicarrier allocating and measuring enabling gate that is UE, the factors such as RRM (Radio Resource Management, RRM) algorithm of the setting of this measurement startup thresholding and noise circumstance, coverage and the network side of current service cell region are relevant.This network equipment can be the multicarrier configuration S-measure parameter value of UE according to self needs.
When network equipment is each member carrier configuration separately independently during S-measure, then network equipment need send to UE with the S-measure of each member carrier correspondence, the S-measure of each member carrier correspondence can send to UE by same message, also can send to UE by different message.
When network equipment is that each member carrier configuration set is separately independently during S-measure, then network equipment need send to UE with the S-measure of each member carrier group correspondence, the S-measure of each member carrier group correspondence can send to UE by same message, also can send to UE by different message.
When network equipment disposed unified S-measure for all member carriers, then network equipment needed the S-measure that will unify configuration to send to UE.
Need to prove, network equipment can be at RRC (Radio Resource Control, radio resource control) IE (information elements is disposed in the measurement that connects reallocation message, information element) the S-measure value of configuration member's carrier wave in, at this moment, network equipment need connect reallocation message by RRC S-measure is sent to UE.Certainly, in actual applications, this network equipment can also be in other message (for example, message A) the S-measure value of configuration member's carrier wave, and S-measure is sent to UE by message A, give unnecessary details no longer in detail among the present invention.
Satisfy to measure starting under the situation of thresholding, UE will independently start or close separately relevant measurement in carrier wave or the carrier wave set according to the signal quality of each member carrier or carrier wave set.Wherein, UE will obtain the signal quality of each member carrier or carrier wave set, measure enabling gate in limited time when this signal quality is lower than, and then UE needs independently to start measurement relevant in corresponding member carrier or the carrier wave set; Measure enabling gate in limited time when this signal quality is higher than, then UE need independently close measurement relevant in corresponding member carrier or the carrier wave set.
Concrete, first kind of situation, when network equipment is each member carrier configuration separately independently during S-measure, in this step, UE will start or close the measurement that this carrier wave is correlated with reference to the signal quality of each member carrier.For example, when having only the signal quality of member carrier 1 to be lower than the S-measure of member carrier 1, then only need to start measurement relevant in the member carrier 1, and do not need to start measurement relevant in other member carriers.
Second kind of situation, when network equipment is each member carrier configuration set separately independently during S-measure, in this step, UE will start or close the relevant measurement of this carrier wave set with reference to the signal quality of each member carrier group.For example, when having only the signal quality of member carrier group 1 to be lower than the S-measure of member carrier group 1, then only need to start measurement relevant in the member carrier group 1, and do not need to start measurement relevant in other member carrier groups.
In this case, definite mode of the signal quality of each member carrier group includes but not limited to:
(1) the best carrier wave of signal quality in the current member carrier group, for example, comprise member carrier 1 and member carrier 2 in the member carrier group, when the signal quality of member's carrier wave 1 is better than member carrier 2, then select the signal quality of the signal quality of member carrier 1 as this member carrier group.
Perhaps,
(2) the poorest carrier wave of signal quality in the current member carrier group for example, when the signal quality of member's carrier wave 1 is better than member carrier 2, is selected the signal quality of the signal quality of member carrier 2 as this member carrier group.
Perhaps,
(3) if when having special cell (particular cell) in the current member carrier group, select this specialcell corresponding UE that security parameter input and NAS (Non Access Stratum are provided, Non-Access Stratum) carrier wave of mobility information, and with the signal quality of this carrier wave signal quality as this member carrier group.
Perhaps;
(4) with the comprehensive assessment result of all member carrier signal qualitys in the current member carrier group signal quality as this member carrier group, for example, all member carrier signal qualitys are replaced number mean value or weighted average, and with this algebraic mean value or the weighted average signal quality as this member carrier group.
The third situation, when network equipment during for the unified S-measure of all member carriers configuration, in this step, if not grouping between the member carrier, then UE starts with reference to the signal quality of each member carrier or closes the relevant measurement of this carrier wave; And if divided into groups between the member carrier, then UE starts with reference to the signal quality of each member carrier group or closes the relevant measurement of this carrier wave set.
Need to prove that the member carrier of the UE that is mentioned in the said process all refers to the current carrier wave that has disposed, comprise the carrier wave (if having the activation process) that disposes but be not activated.Wherein, in the activation process, the main purpose of introducing activation is according to the opening and closing member carrier of the flexible in size of traffic carrying capacity, can play the effect of power saving, and need not be frequent member carrier is configured, saved signaling consumption; In addition, the activation process can be faster than configuration process.For the carrier wave of deexcitation, the UE side still can keep this carrier configuration information, improves or professional quantitative change is carried out activation manipulation by network side to this carrier wave when big in the carrier channel quality, carries out data dispatch then.
As seen, the method that the application of the invention provides, by being member carrier and/or carrier wave set allocating and measuring startup thresholding, make that subscriber equipment can be according to measuring the measurement that starts thresholding and signal quality startup or cut out member carrier and/or carrier wave set, thereby solved how terminal starts measurement under a plurality of work sub-district according to the multi-carrier signal quality problem, save the UE electric weight, for the network management multicarrier provides greater flexibility.
For technical scheme provided by the invention more clearly is described, be elaborated below in conjunction with the measurement collocation method of several concrete application scenarioss to multicarrier system that the embodiment of the invention proposes.
Scene 1, network equipment disposes separately independently S-measure for each member carrier, and under this scene, UE will start or close the relevant measurement of this carrier wave with reference to the signal quality of each member carrier.
Should be with under the scene, the UE polymerization three member carriers, be respectively CC (member carrier) 1, CC2 and CC3.Network equipment is that three CC of UE have disposed corresponding S-measure value respectively, wherein, the corresponding S-measure-1 of CC1, the corresponding S-measure-2 of CC2, the corresponding S-measure-3 of CC3, and the measurement of having disposed some frequencies according to the RRM algorithm at 3 CC respectively.
When the UE polymerization is operated on three member carriers, UE will obtain the signal quality of each member carrier, if when the signal quality of first three member carrier all is higher than separately S-measure value, then do not need to start the relevant measurement of each member carrier, and in subsequent process, if the channel status of CC2 begins variation, when making the signal quality of CC2 be lower than the S-measure-2 value, then UE need start the upward relevant measurement of CC2, promptly starts all measurements that CC2 goes up configuration.Wherein, measuring process is that the measurement of channel quality is carried out in all sub-districts under the measuring object (frequency) relevant with CC2 of network configuration, promptly measures the RSRP and/or the RSRQ of sub-district.Afterwards, if the signal quality of CC2 begins again to improve, when being higher than the S-measure-2 value again, then UE need close CC2 and go up relevant measurement, promptly closes all measurements that CC2 goes up configuration.
Scene 2, network equipment are each member carrier configuration set S-measure independently separately, and under this scene, UE will start or close the relevant measurement of this carrier wave set with reference to the signal quality (carrier wave that signal quality is the poorest) of each member carrier group.
Should be with under the scene, the UE polymerization four member carriers, be respectively CC1, CC2, CC3 and CC4, to be UE organize (i.e. { CC1 at two CC to network side, CC2} and { CC3, CC4}) disposed corresponding S-measure value respectively, wherein, { CC1, the corresponding S-measure-1 of CC2}, CC3, the corresponding S-measure-2 of CC4}, and according to the RRM algorithm at 4 CC and 2 CC configuration set the measurement of some frequencies.
When the UE polymerization is operated on four member carriers, UE will obtain the signal quality of four CC, if the signal quality of four CC of current two carrier wave set all is higher than S-measure value separately, then not need to start the relevant measurement of each member carrier group.Is example to select the poorest carrier wave of signal quality in the current member carrier group for the signal quality of this member carrier group, when then the signal quality of the signal quality of CC1 and CC2 is all greater than S-measure-1, { CC1, the signal quality of CC2} is higher than S-measure-1 to carrier wave set.
And in subsequent process, if carrier wave set { CC3, the channel status of CC3 begins variation among the CC4}, when making the signal quality of CC3 be lower than the S-measure-2 value, carrier wave set { CC3 is described then, the signal quality of CC4} is lower than S-measure-2, at this moment, UE need start carrier wave set { CC3, all measurements of the last configuration of CC4}, comprise CC3 and CC4 measurement and carrier wave set { CC3, the measurement on the CC4} separately.Afterwards, if the signal quality of CC3 begins again to improve (still being lower than CC4), the new peak of laying equal stress on is when the S-measure-2 value, then UE need close carrier wave set { CC3, CC3 and CC4 measurement and carrier wave set { CC3, the measurement on the CC4} separately promptly closed in the last relevant measurement of CC4}.
Scene 3, network equipment be for the unified S-measure of all member carriers configuration, and under this scene, if not grouping between the member carrier, then UE starts with reference to the signal quality of each member carrier or closes the relevant measurement of this carrier wave; And if divided into groups between the member carrier, then UE starts with reference to the signal quality of each member carrier group or closes the relevant measurement of this carrier wave set.
Should be with under the scene, the UE polymerization three member carriers, be respectively CC1, CC2 and CC3, and not grouping between three member carriers.Network equipment is that three CC of UE have disposed the unified S-measure value of UE rank, and has disposed the measurement of some frequencies at 3 CC according to the RRM algorithm.
When the UE polymerization is operated on three member carriers, UE will obtain the signal quality of each member carrier, all be higher than unified S-measure value if work as the signal quality of first three member carrier, then not need to start the relevant measurement of each member carrier.And in subsequent process,, make the signal quality of CC2 be lower than unified S-measure value if the channel status of CC2 begins variation, then UE need start the upward relevant measurement of CC2, promptly starts all measurements that CC2 goes up configuration.Afterwards, if the signal quality of CC2 begins again to improve, the new peak of laying equal stress on is when the S-measure value, and then UE need close CC2 and go up relevant measurement, promptly closes all measurements that CC2 goes up configuration.
Scene 4, network equipment are each member carrier configuration set S-measure independently separately, and under this scene, UE will start or close the relevant measurement of this carrier wave set with reference to the integrated signal quality of each member carrier group.
Should be with under the scene, the UE polymerization four member carriers, be respectively CC1, CC2, CC3 and CC4, to be UE organize (i.e. { CC1 at two CC to network side, CC2} and { CC3, CC4}) disposed corresponding S-measure value respectively, wherein, { CC1, the corresponding S-measure-1 of CC2}, CC3, the corresponding S-measure-2 of CC4}, and according to the RRM algorithm at 4 CC and 2 CC configuration set the measurement of some frequencies.
When the UE polymerization is operated on four member carriers, UE will obtain the signal quality of four CC, and the signal quality of two member carriers in each carrier wave set is done weighted average, and with the signal quality of weighted average as this carrier wave set.If the average weighted signal quality of current two carrier wave set all is higher than S-measure value separately, then do not need to start the relevant measurement of each member carrier group.
And in subsequent process, if carrier wave set { CC3, the channel conditions of CC4} begins variation, when making the integrated signal quality of CC3 and CC4 be lower than the S-measure-2 value, carrier wave set { CC3 is described then, the signal quality of CC4} is lower than S-measure-2, at this moment, UE need start carrier wave set { CC3, all measurements of the last configuration of CC4}, comprise CC3 and CC4 measurement and carrier wave set { CC3, the measurement on the CC4} separately.Afterwards, if the signal quality of CC3 and CC4 begins again to improve, and the integrated signal quality of the two is when being higher than the S-measure-2 value, and then UE need close CC3 and CC4 measurement and carrier wave set { CC3, the measurement on the CC4} separately.
Scene 5, network equipment disposes separately independently S-measure (comprising configuration un-activation carrier wave) for each member carrier, and under this scene, UE will start or close the relevant measurement of this carrier wave with reference to the signal quality of each member carrier.
Should be with under the scene, the UE polymerization three member carriers, be respectively CC1, CC2 and CC3.Network equipment is that three CC of UE have disposed corresponding S-measure value respectively, wherein, the corresponding S-measure-1 of CC1, the corresponding S-measure-2 of CC2, the corresponding S-measure-3 of CC3, and the measurement of having disposed some frequencies according to the RRM algorithm at 3 CC respectively.
Because the minimizing of current transmitted data amount has been carried out deactivating operation to CC2, the UE side has still kept the configuration information (comprising measurement configuration information) of CC2.At this moment, UE also needs to obtain the signal quality of CC2, and promptly UE will obtain the signal quality of each member carrier, if all be higher than separately S-measure value when the signal quality of first three member carrier, does not then need to start the measurement that each member carrier is correlated with.And in subsequent process, if the channel status of CC2 begins variation, when making the signal quality of CC2 be lower than the S-measure-2 value, then UE need start CC2 and goes up relevant measurement, promptly starts all measurements that CC2 goes up configuration.Afterwards, if the signal quality of CC2 begins again to improve, when being higher than the S-measure-2 value again, then UE need close CC2 and go up relevant measurement, promptly closes all measurements that CC2 goes up configuration.
