Description

A kind of ascending-descending subframes method for reconfiguration of Microcell and device

Technical field

The present invention relates to the communications field, particularly relate to a kind of ascending-descending subframes method for reconfiguration and device of Microcell.

Background technology

Along with the sharp increase with business demand that develops rapidly of mobile communication, Micro-cell (can be described as Small Cell, also can referred to as Microcell, small-cell etc.) technology becomes focus.At present, most of data service occurs in indoor, and the proportion that data service occurs in indoor gets more and more, therefore, the application of low power nodes will be more extensive, in the Microcell occurring in low power nodes and provide covers by a large amount of data services, for low power nodes, as microcellulor (Pico), Home eNodeB (Home eNodeB, HeNB) is more for the transmission of data service, and advantage is power saving, be with roomy, and number of users is far fewer than macrocellular.In such a scenario, the business comparison in difference of Microcell is obvious, and namely upstream data is less, and downlink data is more.

At Long Term Evolution (the Long Term Evolution of 3-G (Generation Three mobile communication system), LTE) in system, Rel-12 time division duplex (Time Division Duplexing, TDD) enhancing interference management and service adaptation (Enhanced Interference Management, eIMTA) technology mainly solve the problem of how to carry out service adaptation and interference management when network design is carried out in Microcell.Wherein, service adaptation mainly refers to and to configure according to the business demand dynamic conditioning ascending-descending subframes of user, thus improves frequency spectrum service efficiency.TDD duplex mode is owing to adopting non-symmetrical spectrum, the frequency spectrum that can some be utilized neatly scrappy, and more easily obtain continuous print large bandwidth frequency spectrum, in addition, because uplink and downlink channel occupancy resource in TD-LTE system is by adjustment uplink and downlink timeslot ratio mode flexible configuration, be very suitable for the non-symmetrical services such as IP Packet Service.At present, TD-LTE system supports 7 kinds of different uplink-downlink configuration, and uplink-downlink configuration information notifies user by system broadcast information.

In macro-cellular network deployment, because business is relatively stable to uplink and downlink timeslot ratio conditions of demand, simultaneously in order to avoid up-downgoing interference at crossed slot.Macrocell adopts a fixing uplink-downlink configuration usually, and the uplink-downlink configuration of neighbor cell is consistent.Therefore, in existing system, reality does not play TD-LTE sub-frame allocation and adapts to this advantage to service conditions.

But, for Microcell (Pico and HeNB), due to features such as its business demand are obvious, transmitting power is low, therefore, coverage distance is comparatively near, interference is less, and self-adaptative adjustment ascending-descending subframes configures the advantage that the service efficiency improving system resource can play TD-LTE better.

In prior art, the dynamic ascending-descending subframes in Microcell is reshuffled between the adjacent Microcell of main dependence and is carried out information interaction realization, for avoiding the interference between ascending-descending subframes, for blank subframe is added in the Microcell of serious interference between ascending-descending subframes.Realize dynamic ascending-descending subframes by information interaction between Microcell to reshuffle, can cause and reshuffle the low and poor performance of efficiency; In addition, avoid the interference between ascending-descending subframes by this mode of interpolation blank subframe, the availability of frequency spectrum can be caused low, throughput degradation, certain loss can be caused to systematic function further.

Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, is not whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

It should be noted that, in the embodiment of the present invention, by be applied to network side realize Microcell control device be called central control unit, this central control unit can be realized by computer applied algorithm, also can realize the function of central control unit in the integrated hardware module of network side.

Microcell bunch is defined as the set be made up of one or more Microcell.After the division of Microcell bunch, disturb comparatively large between Microcell in Microcell bunch, therefore, need to adopt identical ascending-descending subframes configuration to avoid interference, and interference is less mutually between Microcell bunch, ascending-descending subframes configuration can be adjusted adaptively according to service condition.

At pretreatment stage, all Microcells in Microcell bunch report real resource occupancy, cache resources occupancy and the equivalent resources occupancy of the up-downgoing of each Microcell to central control unit.

Concrete, when dynamic ascending-descending subframes reshuffles cycle T _dduring arrival, Microcell performs up-downgoing real resource occupancy statistics and reports.When arriving, the real resource occupancy of Microcell was added up and reported value calculating method as follows i-th dynamic TDD ascending-descending subframes cycle of reshuffling:

$R_{\mathrm{ul}\_\mathrm{Act}}\left(i\right)=\underset{j=i*T_d/10-T_s/T_d+1}{\overset{i*T_d/10}{\mathrm{\Σ}}}{N}_{\mathrm{ul}\_\mathrm{PRB}}\left(j\right)/N_{\mathrm{ul}\_\mathrm{PRB}\_\mathrm{Total}}/(T_s/T_d)$

$R_{\mathrm{dl}\_\mathrm{Act}}\left(i\right)=\underset{j=i*T_d/10-T_s/T_d+1}{\overset{i*T_d/10}{\mathrm{\Σ}}}{N}_{\mathrm{dl}\_\mathrm{PRB}}\left(j\right)/N_{\mathrm{dl}\_\mathrm{PRB}\_\mathrm{Total}}/(T_s/T_d)$

Wherein, R _{ul_Act}(i) and R _{dl_Act}i () is the up-downgoing real resource occupancy that i-th dynamic TDD ascending-descending subframes reshuffles Microcell corresponding to cycle respectively, i*T _d/ 10 represent that i-th dynamic TDD ascending-descending subframes reshuffles radio frames label corresponding to cycle, j=i*T _d/ 10-T _s/ T _d+ 1 represent i-th dynamic TDD ascending-descending subframes reshuffle the cycle before T _s/ T _dindividual radio frames label, N _{ul_PRB}(j) and N _{dl_PRB}j () represents that in a jth radio frames, the average each subframe of all carryings of up-downgoing takies PRB number respectively; N _{ul_PRB_Total}and N _{dl_PRB_Total}represent the available PRB number that each subframe of up-downgoing is total respectively, T _dfor dynamic ascending-descending subframes reshuffles the cycle, T _sfor real resource occupancy measurement period.

In particular cases, if i*T _d/ 10-T _s/ T _d+ 1≤0, then real resource occupancy computational methods are as follows:

$R_{\mathrm{ul}\_\mathrm{Act}}\left(i\right)=\underset{j=1}{\overset{i*T_d/10}{\mathrm{\Σ}}}{N}_{\mathrm{ul}\_\mathrm{PRB}}\left(j\right)/N_{\mathrm{ul}\_\mathrm{PRB}\_\mathrm{Total}}/(i*T_d/100)$

$R_{\mathrm{dl}\_\mathrm{Act}}\left(i\right)=\underset{j=1}{\overset{i*T_d/10}{\mathrm{\Σ}}}{N}_{\mathrm{dl}\_\mathrm{PRB}}\left(j\right)/N_{\mathrm{dl}\_\mathrm{PRB}\_\mathrm{Total}}/(i*T_d/100)$

Concrete, when dynamic ascending-descending subframes reshuffles cycle T _dduring arrival, Microcell performs up-downgoing cache resources occupancy statistics and reports.When arriving, the cache resources occupancy of Microcell was added up and reported value calculating method as follows i-th dynamic TDD ascending-descending subframes cycle of reshuffling:

R _{ul_BSR}(i)＝Data _{ul_BSR}(i)/η _ul(i)/W _ul

R _{dl_BSR}(i)＝Data _{dl_BSR}(i)/η _dl(i)/W _dl

Wherein, R _{ul_BSR}(i), R _{dl_BSR}i () is the up-downgoing cache resources occupancy that i-th dynamic TDD ascending-descending subframes reshuffles Microcell corresponding to cycle respectively, Data _{ul_BSR}(i) and Data _{dl_BSR}i () represents up-downgoing buffer data size during i-th cycle arrival respectively, η _ul(i) and η _dli () represents the up-downgoing average spectral efficiency (ase) in i-th cycle respectively, W _uland W _dlrepresent the up-downgoing available bandwidth of Microcell respectively, T _dfor dynamic ascending-descending subframes reshuffles the cycle, T _sfor real resource occupancy measurement period.

Concrete, when dynamic ascending-descending subframes reshuffles cycle T _dduring arrival, Microcell performs up-downgoing equivalent resources occupancy statistics and reports.When i-th dynamic TDD ascending-descending subframes cycle of reshuffling arrives, the equivalent resources occupancy of Microcell is added up and reports value calculating method as follows:

$R_{\mathrm{ul}\_\mathrm{Eff}}\left(i\right)=\frac{N_{\mathrm{ul}\_\mathrm{PRB}}\left(i\right)}{R_{\mathrm{ul}\_\mathrm{SBR}}\left(i\right)}\×\underset{m_{\mathrm{ul}}=1}{\overset{M_{\mathrm{ul}}}{\mathrm{\Σ}}}{R}_{m_{\mathrm{ul}}}\left(i\right)/N_{\mathrm{ul}\_\mathrm{PRB}\_\mathrm{Total}}$

$R_{\mathrm{dl}\_\mathrm{Eff}}\left(i\right)=\frac{N_{\mathrm{dl}\_\mathrm{PRB}}\left(i\right)}{R_{\mathrm{dl}\_\mathrm{SBR}}\left(i\right)}\×\underset{m_{\mathrm{dl}}=1}{\overset{M_{\mathrm{dl}}}{\mathrm{\Σ}}}{R}_{m_{\mathrm{dl}}}\left(i\right)/N_{\mathrm{dl}\_\mathrm{PRB}\_\mathrm{Total}}$

In the embodiment of the present invention, the real resource occupancy that central control unit reports based on each Microcell, cache resources occupancy and equivalent resources occupancy, in carrying out bunch during the ascending-descending subframes configuration of Microcell, specifically perform following operation, consult shown in Fig. 1.

Step 101: determine the Microcell sub-clustering state existed in current system

Concrete, when central control unit performs the division of Microcell bunch, receive Reference Signal Received Power (the Reference Signal Receive Power of the adjacent cell that each Microcell reports respectively, RSRP), whenever the RSRP of an adjacent cell of a Microcell be not less than default bunch divide threshold value time, the adjacent cell of this Microcell and this Microcell is divided into cluster, until all Microcell and adjacent cell thereof divide complete, thus obtain multiple bunches, the merging that the condition preset according to central control unit is further carried out bunch, finally determine the Microcell sub-clustering state existed in current system.

Further, after determining the Microcell sub-clustering state existed in current system, before the resource occupation state that each Microcell in each bunch of statistics reports, if there is one of following state, then do not adjust the ascending-descending subframes configuration of all Microcells in this bunch;

The first situation is: determining that the Microcell quantity sum in some bunch is greater than default bunch scale threshold value, judging the ascending-descending subframes configuration not adjusting all Microcells in this bunch.

Such as, suppose always to have 100 Microcells in bunch A of Microcell, exceeded bunch scale threshold value C of system regulation _th, regulation C _th=80, now do not advise the ascending-descending subframes configuration adjusting all Microcells in bunch A, the probability consistent due to Microcell up-downgoing business all in bunch A is less, if have adjusted the ascending-descending subframes configuration of all Microcells in bunch A, ascending-descending subframes configuration can not be realized along with the adaptive adjustment of change of business, the business completion rate of each Microcell in bunch A may be affected on the contrary.

Second case is: when determining to exist in some bunch with frequency macrocell, judge the ascending-descending subframes configuration not adjusting all Microcells in this bunch.

Such as, suppose there is one in bunch B of Microcell with frequency macrocell D, now do not adjust the ascending-descending subframes configuration of all Microcells in bunch B, if have adjusted the ascending-descending subframes configuration of all Microcells in bunch B, make the ascending-descending subframes configuration of the most of Microcells in bunch B and the ascending-descending subframes configuration consistency of macrocell D, and frequency range is identical, each Microcell in bunch B can be caused like this to be subject to serious up-downgoing interference, to affect the systematic function of each Microcell.

The third situation is: when determining to there is adjacent frequency macrocell in some bunch, judges the TDD ascending-descending subframes configuration not adjusting all Microcells in this bunch.

Such as, suppose to there is an adjacent frequency macrocell E in bunch C of Microcell, now do not adjust the ascending-descending subframes configuration of all Microcells in bunch C, if have adjusted the ascending-descending subframes configuration of all Microcells in bunch C, make the ascending-descending subframes configuration of the most of Microcells in bunch C and the ascending-descending subframes configuration consistency of macrocell E, and frequency range is close, each Microcell in bunch B can be caused like this to be subject to serious up-downgoing interference, to affect the systematic function of each Microcell.

Step 102: add up the resource occupation state that each Microcell in each bunch reports, resource occupation state at least comprises the up-downgoing real resource occupancy of a Microcell, up-downgoing cache resources occupancy and up-downgoing equivalent resources occupancy.

Concrete, the up-downgoing real resource occupancy of a Microcell is that the actual PRB of the taking number of each subframe carried based on up-downgoing calculates, and specific formula for calculation is as follows:

$R_{\mathrm{ul}\_\mathrm{Act}}\left(i\right)=\underset{j=i*T_d/10-T_s/T_d+1}{\overset{i*T_d/10}{\mathrm{\Σ}}}{N}_{\mathrm{ul}\_\mathrm{PRB}}\left(j\right)/N_{\mathrm{ul}\_\mathrm{PRB}\_\mathrm{Total}}/(T_s/T_d)$

$R_{\mathrm{dl}\_\mathrm{Act}}\left(i\right)=\underset{j=i*T_d/10-T_s/T_d+1}{\overset{i*T_d/10}{\mathrm{\Σ}}}{N}_{\mathrm{dl}\_\mathrm{PRB}}\left(j\right)/N_{\mathrm{dl}\_\mathrm{PRB}\_\mathrm{Total}}/(T_s/T_d)$

Wherein, R _{ul_Act}(i) and R _{dl_Act}i () is the up-downgoing real resource occupancy that i-th dynamic ascending-descending subframes reshuffles Microcell corresponding to cycle respectively, i*T _d/ 10 represent that i-th dynamic TDD ascending-descending subframes reshuffles radio frames label corresponding to cycle, j=i*T _d/ 10-T _s/ T _d+ 1 represent i-th dynamic TDD ascending-descending subframes reshuffle the cycle before T _s/ T _dindividual radio frames label, N _{ul_PRB}(j) and N _{dl_PRB}j () represents that in a jth radio frames, the average each subframe of all carryings of up-downgoing takies PRB number respectively; N _{ul_PRB_Total}and N _{dl_PRB_Total}represent the available PRB number that each subframe of up-downgoing is total respectively, T _dfor dynamic ascending-descending subframes reshuffles the cycle, T _sfor real resource occupancy measurement period.

The up-downgoing cache resources occupancy of a Microcell calculates based on the buffer data size of up-downgoing, and specific formula for calculation is as follows:

R _{ul_BSR}(i)＝Data _{ul_BSR}(i)/η _ul(i)/W _ul

R _{dl_BSR}(i)＝Data _{dl_BSR}(i)/η _dl(i)/W _dl

Wherein, R _{ul_BSR}(i), R _{dl_BSR}i () is the up-downgoing cache resources occupancy that i-th dynamic ascending-descending subframes reshuffles Microcell corresponding to cycle respectively, Data _{ul_BSR}(i) and Data _{dl_BSR}i () represents up-downgoing buffer data size during i-th cycle arrival respectively, η _ul(i) and η _dli () represents the up-downgoing average spectral efficiency (ase) in i-th cycle respectively, W _uland W _dlrepresent the up-downgoing available bandwidth of Microcell respectively, T _dfor dynamic ascending-descending subframes reshuffles the cycle, T _sfor real resource occupancy measurement period.

The up-downgoing equivalent resources occupancy of a Microcell ensures what bit rate calculation obtained based on up-downgoing business, and specific formula for calculation is as follows:

$R_{\mathrm{ul}\_\mathrm{Eff}}\left(i\right)=\frac{N_{\mathrm{ul}\_\mathrm{PRB}}\left(i\right)}{R_{\mathrm{ul}\_\mathrm{SBR}}\left(i\right)}\×\underset{m_{\mathrm{ul}}=1}{\overset{M_{\mathrm{ul}}}{\mathrm{\Σ}}}{R}_{m_{\mathrm{ul}}}\left(i\right)/N_{\mathrm{ul}\_\mathrm{PRB}\_\mathrm{Total}}$

$R_{\mathrm{dl}\_\mathrm{Eff}}\left(i\right)=\frac{N_{\mathrm{dl}\_\mathrm{PRB}}\left(i\right)}{R_{\mathrm{dl}\_\mathrm{SBR}}\left(i\right)}\×\underset{m_{\mathrm{dl}}=1}{\overset{M_{\mathrm{dl}}}{\mathrm{\Σ}}}{R}_{m_{\mathrm{dl}}}\left(i\right)/N_{\mathrm{dl}\_\mathrm{PRB}\_\mathrm{Total}}$
