Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
First it should be noted that: in various embodiments of the present invention, can be in advance to the communication system of each standard, each self-configuring allows the carrier wave gross power of using, make the gross power sum of the communication system of each standard can equal the rated power of the power amplifier of power amplifier.
To the power configuration of the communication system of each standard can with power amplifier, (Power Amplifier be called for short: PA) be unit, carry out in PA inside.If there are a plurality of PA, each PA inside all adopts scheme described in the embodiment of the present invention to carry out independent process, or carries out Combined Treatment between a plurality of PA, to meet larger power amplifier demand.
The flow chart of the power sharing method that Fig. 1 provides for one embodiment of the invention.In the present embodiment, the communication system of at least two kinds of standards shares same power amplifier, and for example, the communication system of the communication system of GSM standard and UMTS standard shares same power amplifier.As shown in the figure, the method comprises:
For the communication system that shares each standard of same power amplifier, can be according to the power demand of the communication system of wherein one or more standards, determine that whether the communication system for some standards has power residue, shares thereby can determine whether to carry out power between different systems communication system.
If determine and will carry out power share between different systems communication system, can dynamically adjust the available horsepower of the communication system of wherein one or more standards.Concrete adjustment mode can have multiple, and wherein part mode can be with reference to the associated description of subsequent embodiment.
The method of the present embodiment when determining that according to power demand will carry out power shares, is carried out power and is shared between different systems communication system, thereby the power of having realized dynamic flexible between the communication system of at least two kinds of standards is shared.
It should be noted that in addition, if have at least the communication system of a standard also to use other power amplifiers in the communication system of each standard of shared same power amplifier simultaneously, the available horsepower of the communication system of above-mentioned wherein one or more standards of adjustment comprises: adjust the ratio of the power that the communication system that is used simultaneously other one or more power amplifiers of this power amplifier being shared and described other one or more power amplifiers takies, use the communication system of other one or more power amplifiers to take the power on this power amplifier being shared to reduce simultaneously.
Wherein, the mode of adjusting the ratio of the power that the communication system that is used simultaneously other power amplifiers of this power amplifier being shared and other power amplifiers takies can have multiple, as long as can realize the object that the described communication system of using other power amplifiers of reduction takies the power on this power amplifier being shared simultaneously.For example, suppose that UMTS and GSM share the first power amplifier, simultaneously GSM is also used the second power amplifier can adjust the ratio of the power that the first power amplifier and the second power amplifier taken by GSM simultaneously, to reduce GSM, take the power on the first power amplifier, because the gross power that GSM is required is fixed, therefore, when GSM takies more power on the second power amplifier, GSM shared power on the first power amplifier can reduce, thereby can be so that the power of the first power amplifier is taken by UMTS as far as possible.A kind of mode wherein can be: preferentially using the power division of the second power amplifier to GSM as its available horsepower.It should be noted that, according to the different different demands that disposes, sometimes will evenly use the power of two power amplifiers.For example, at MIMO(Multiple Input Multiple Output, Multiinputoutput) under scene, now can be so that GSM be evenly used the power of the first power amplifier and the second power amplifier as far as possible.Wherein, can adopt transmit diversity or other modes from GSM to UMTS, to share power.
The flow chart of the power sharing method that Fig. 2 provides for another embodiment of the present invention, in the present embodiment, the communication system of sharing a plurality of standards of same power amplifier is called to the communication system of the first standard and the communication system of one or more other standards, as shown in the figure, comprises:
Particularly, can know in the following way the sharable dump power of each standard communication system:
When predetermined period arrives, the gross power of the current configuration of communication system of a standard is deducted to current power demand, the difference obtaining is sharable dump power; Or, when predetermined period arrives, the available horsepower of the current configuration of communication system of a standard being deducted to current power demand and reserved power, the difference obtaining is sharable dump power; Or, using the constant power value in the gross power of the current configuration of communication system of a standard or fixed proportion as described sharable dump power.
Wherein, the communication system that current power demand refers to a standard is in order to maintain the needed power of current operation.For example, the current power demand of GSM standard refer to current each time slot demand power of 8 time slots and in maximum, wherein comprise pilot transmit power.At time slot time division multiple access, (Time Division Multiple Access is called for short: TDMA) in technology, a frame is comprised of 8 time slots.GSM pilot transmit power refers to that (Broadcast Control Channel is called for short: power used during transmitting pilot signal BCCH) in Broadcast Control Channel.Because having conventionally, pilot signal makes to provide the forward direction CDMA channel time limit, the functions such as coherent demodulation phase reference, be very important signal, its transmitting power will remain unchanged, therefore not using its as sharable dump power the communication system for other standards.
Wherein, reserved power refers to the idle power of keeping for standard to use, in order to the arrival of the burst service of probable to aware or for the communication system that meets this standard the power demand in next predetermined period.This reserved power can be set to any number according to actual needs.
It should be noted that, predetermined period herein can arrange according to actual needs.And the communication system of the first above standard can be any one sharing in the communication system of a plurality of standards of power amplifier.
Particularly, if the network load of the communication system of one or more other standards, as high speed downlink packet access, (High Speed Downlink Packet Access, is called for short: HSDPA) network load is lighter, do not need to receive while sharing power, reject described dump power.Or, can be for the minimum effective time (ms of unit) of the communication system of one or more other standards if be less than the remaining time that this dump power can be shared, also can reject shared power, with after avoiding carrying out power and sharing, service time to shared power is too short, and utilance is too low.Wherein, refer to remaining time within a shared cycle, from determining that the communication system that dump power is shared to one or more other standards uses between this shared end cycle during this period of time.
Particularly, if when the sharable dump power of the communication system of the first standard is more than or equal to the first thresholding, determine that the sharable dump power of the communication system of the first standard meets default shared condition; Or, when if the difference of the sharable dump power of the communication system of the sharable dump power of the communication system of the first standard and one or more other standards is more than or equal to the second thresholding, determine that the sharable dump power of the communication system of the first standard meets default shared condition.Certainly, according to different demands, can also there is other mode to determine that whether the sharable dump power of the communication system of the first standard meets default shared condition, will not enumerate herein.In addition, when if the sharable dump power of the communication system of the first standard does not meet default shared condition, whether the sharable dump power that can redefine the communication system of another one standard meets default shared condition, if the sharable dump power of the communication system of another one standard meets default shared condition, the power of this communication system can be shared to the communication system of other standards.
For example, the communication system of supposing the first standard is GSM, if when GSM dump power is more than or equal to the first thresholding, illustrates that now the power demand of GSM standard is lower, a part of GSM dump power can be shared to other standards; Otherwise illustrate that now the power demand of GSM standard itself is also very high, should not share power to other standards, in order to avoid affect the normal operation of GSM standard self.
Again for example, the communication system of supposing the first standard is GSM, the communication system of other standards is UMTS, if a upper cycle GSM standard has been shared power to UMTS pattern, therefore only have and when the difference of the sharable dump power of gsm communication system and the sharable dump power of UMTS is more than or equal to the second thresholding, just meet the condition of sharing, to guarantee to only have when GSM has abundant dump power, just to UMTS, share power, to avoid frequently carrying out back-off and the shared operation of repetition power, with mitigation system, bear.Except GSM and UMTS, can also there is the communication system of other standards, for example (Long Term Evolution is called for short: LTE), and no matter be the communication system of which kind of standard, the thinking of processing is that similarly the present embodiment does not exemplify one by one Long Term Evolution.
It should be noted that, above take by GSM, power is shared to UMTS as example describes, in actual conditions, also can power be shared to GSM by UMTS.The numerical value of above the first thresholding and the second thresholding can be set according to actual needs, and the embodiment of the present invention does not limit this.
In addition, when if the communication system of the first standard is GSM, obtain the sharable dump power of communication system of the first standard in above-mentioned steps 201 before, can further include: whether the quantity that judges the non-main B carrier wave in GSM carrier wave reaches default numerical value, if reach default numerical value, carry out the step of the sharable dump power of the communication system of obtaining the first standard; Wherein, default numerical value can be any positive integer, and main B carrier wave refers to the carrier wave of pilot signal transmitted, and non-main B carrier wave refers to the carrier wave except main B carrier wave.In GSM, in order to guarantee that it normally moves, can be the enough power of main B allocation of carriers, therefore, can take a large amount of available horsepowers, when the quantity of non-main B carrier wave is abundant, may there be a large amount of dump powers to share to one or more other communication systems, can when sharing, dump power judge in advance the quantity of non-main B carrier wave judging whether so, if when the quantity of non-main B carrier wave does not reach default numerical value, can avoid follow-up judgement.
If determine and will carry out power share between different systems communication system, can dynamically adjust the available horsepower of the communication system of wherein one or more standards.Concrete adjustment mode can have multiple, and wherein part mode can be with reference to the associated description of subsequent embodiment.
The flow chart of the power sharing method that Fig. 3 provides for another embodiment of the present invention, as shown in the figure, comprising:
The implementation of this step can, with reference to the associated description in figure 1 or Fig. 2, repeat no more herein.
For example, can be first after the gross power of the current configuration of the communication system of the first standard deducts sharable dump power as configuration the available horsepower to the communication system of the first standard; Then on the power basis of the current configuration of one or more other standards, sharable dump power is given to the communication system of one or more other standards according to default regular allocation.
Particularly, sharable dump power can be to the communication system of one or more other standards according to default regular allocation: if there is the communication system of a plurality of other standards, the communication system of described sharable dump power being distributed to described a plurality of other standards successively by the time (for example, in the time of 12, sharable dump power is distributed to UMTS to be shared, in the time of 15, sharable dump power is distributed to LTE and share etc.); Or, can, according to the priority of the communication system of a plurality of other standards, sharable dump power be given to the communication system of a plurality of other standards according to priority order-assigned from high to low; Or, sharable dump power is averagely allocated to the communication system of a plurality of other standards.Wherein, priority can be definite according to the performance of communication system, and for example, the communication system of certain standard easily produces under powered problem, needs to be set to high priority, obtains shared power so that preferential; Or priority also can be definite according to the tendentiousness of operator, and for example, operator wishes preferentially to guarantee the normal operation of UMTS, can this system be set to high priority; Or according to the power demand of the communication system of these standards, power demand is larger, the priority of setting is higher.
For example, the communication system of supposing the first standard is GSM, and the communication system of other standards is UMTS, particularly, obtains UMTS available horsepower=acquisition of sharing after power and shares the shared power that the UMTS available horsepower+agreement before power receives.Wherein, agree to that the shared power receiving is that UMTS agrees to the part power receiving from the sharable dump power of gsm system.Further, the shared power receiving from GSM standard can be for the HSDPA network UMTS standard, this HSDPA network utilisation is shared the power obtaining from GSM standard, because power is more, modulation code available in code division multiple access modulation mode is just more, the content of carrying is just larger, therefore can improve downlink transmission data rate for community user.
It should be noted that in addition, if the absolute value of the difference of the sharable dump power of obtaining when the sharable dump power of the communication system of the first standard that the current preset cycle obtains while arriving and a upper predetermined period arrive is less than or equal to the 3rd thresholding, the available horsepower of communication system that can maintain each standard is constant, otherwise, according to the sharable dump power of the communication system of the first standard, give the communication system of the first standard and the communication system configuration available horsepower of one or more other standards.Thereby in the time of can changing greatly in the dump power of the communication system when the first standard, communication system to one or more other standards provides shared power, and change hour when the dump power of the communication system of the first standard, re-start shared the having little significance of power, therefore can avoid carrying out continually the configuration of available horsepower, increase system burden.Above the 3rd thresholding also can be set according to actual needs.
Above embodiment provides power secret sharing while providing long by the communication system of the first standard to the communication system of other standards, when the communication system of the first standard is carried out to the communication system of one or more other standards after power shares, under the communication system of the first standard, may have burst service, or, the power demand of the communication system that the available horsepower that predicts the communication system of the first standard can not meet the first standard in next predetermined period, can carry out the rollback of power so.By take the situation that occurs burst service, be elaborated as example below.
The situation that GSM and UMTS share a power amplifier of take below describes as example, and the communication system of supposing the first standard is GSM.
As shown in Figure 4, supposing provides power to share by GSM to UMTS, PA has configured three GSM carrier frequency and a UMTS carrier frequency (being expressed as " G3U1 " in Fig. 4), wherein, dotted line position represents that GSM carrier frequency arrives at this burst service that power demand is 20W constantly, when the required power of this burst service exceeds GSM standard after providing shared power for UMTS standard during remaining available free power, current GSM residue available horsepower cannot meet the demand of this burst service, now need to reclaim in time the power that shares to UMTS standard, in Fig. 4, hacures are illustrated on the time slot that burst service distributes carrier frequency are carried out to even peak clipping, to guarantee that overall power requirement is no more than the rated power of the PA of GSM side, simultaneously to UMTS side rollback power.For this reason, another embodiment of the present invention provides again following power sharing method.
The flow chart of the power sharing method that Fig. 5 provides for another embodiment of the present invention, as shown in the figure, may further include after sharing when carrying out power:
Step 401, when the communication system of the first standard being detected, there is burst service to arrive and when the available horsepower of the communication system of this first standard can not meet the power demand after this burst service reaches, after arriving according to burst service, the power demand of communication system of the first standard and the available horsepower of the communication system of the first standard are determined rollback power.
For example, the communication system of supposing the first standard is UMTS, sends the current dump power of time power demand+UMTS of HSDPA data in power demand=UMTS current power demand+next predetermined period of this UMTS in next predetermined period.
Step 402, upgrades the available horsepower of the communication system of the first standard and the communication system of one or more other standards according to rollback power.
Particularly, available horsepower+rollback power of the communication system of the first standard before the available horsepower=renewal of the communication system of the first standard after renewal.Complete after renewal, by power amplifier according to the available horsepower after each system update for carrying out power amplification.
By method described in the present embodiment, when the communication system traffic of the first standard is busy, can dynamically to return the shared power that is shared to the communication system of the second standard by the communication system of the first standard, therefore can further improve the shared flexibility of power, farthest avoid the adverse effect that the service feature of the communication system of the first standard is caused.
It should be noted that in addition, because above-mentioned rollback power process has certain time delay, therefore before completing back-off, may there is PA overload, therefore before carrying out above-mentioned steps 402, can also further carry out following steps: the available horsepower of cutting down the communication system of the first standard according to the difference of the available horsepower of the communication system of the power demand of the communication system of the first standard and the first standard.
For example, the communication system of supposing the first standard is GSM, particularly, can calculate according to following formula: GSM peak clipping power=GSM power demand-GSM available horsepower.
Wherein, GSM peak clipping power refers to the power that will prune from GSM available horsepower.GSM power demand comprises: the demand power (comprising the transmitting power of pilot signal needs) before above-mentioned burst service arrives and the power of above-mentioned burst service demand.
Then according to the GSM peak clipping power calculating, the traffic carrier configuring under GSM is carried out to peak clipping processing.Concrete peak clipping is processed can carry out even peak clipping to each traffic carrier according to the number of the traffic carrier configuring under GSM.Each traffic carrier peak clipping power=GSM peak clipping power/gsm service carrier number.Wherein, traffic carrier refers in BCCH channel for transmitting the carrier wave pilot signal.
It should be noted that, more than to occur that the situation of burst service is that example describes, be understandable that when predicting power demand in next predetermined period of communication system that the available horsepower of the communication system of the first standard can not meet described the first standard, also can adopt similar mode to process, under this scene, can determine rollback power according to the available horsepower of the communication system of the power demand in next predetermined period and the first standard.
The flow chart of the power sharing method that Fig. 6 provides for another embodiment of the present invention, as shown in the figure, the method comprises:
For example, the communication system of supposing one of them standard is GSM, and the communication system of another standard is UMTS.As shown in Figure 7, for the power demand moment schematic diagram of GSM and UMTS, " 0 " " 1 " in figure ... the numbering of 8 time slots in a tdma frame of numeral of " 7 ", as shown in the figure, a slot length (as 2ms) of UMTS can be interpreted as to the maximum power control cycle herein; And a slot length of GSM is the minimum power control cycle.For example, in the time slot of first 2ms of UMTS, in the GSM time slot of " 0 " number, " 1 " number and " 2 " number, obtain the power demand sum of GSM and UMTS, if the power demand sum getting is greater than the rated power of power amplifier, determine that need between GSM and UMTS, carry out power shares.
For example, the communication system of supposing one of them standard is GSM, and the communication system of other standards is UMTS, and detailed process can be as follows:
(1) if the current power demand of GSM has exceeded the available horsepower of GSM, and the current power demand of UMTS does not exceed the available horsepower of UMTS, GSM is carried out to peak clipping processing, and the rated power of GSM peak clipping power=GSM current power demand+UMTS current power demand-power amplifier.
Wherein, the peak clipping that GSM is carried out is processed and is referred to reduction average transmit power, " GSM current power demand+UMTS current power demand " represents GSM and the total power demand of UMTS, the part that this total power demand is exceeded to PA rated power is carried out peak clipping processing as the peak clipping power of GSM to GSM, to guarantee the power demand of UMTS.
(2) if GSM current power demand does not exceed GSM available horsepower, and UMTS current power demand has exceeded UMTS available horsepower, in GSM standard, does not do peak clipping and processes.
(3) if the current power demand of GSM has exceeded the available horsepower of GSM, and the current power demand of UMTS also exceeded the available horsepower of UMTS, GSM carried out to peak clipping processing, and GSM peak clipping power=GSM current power demand-GSM available horsepower.
Because the current power of GSM has exceeded the available horsepower of this GSM, therefore will exceed part carries out peak clipping processing as GSM peak clipping power to GSM.
When the above-mentioned communication system that shares each standard of same power amplifier is GSM and UMTS, this example can further include following steps:
For example, through in step 502, GSM being carried out after peak clipping processing, the complex RF signal of GSM and UMTS still has the rated power that can surpass power amplifier, therefore adopt this step to carry out slicing processing to UMTS, and wherein, slicing is processed and referred to reduction peak-to-average force ratio.
The power control cycle in communication system by method described in the present embodiment based on each standard has realized instantaneous power and has shared, thereby the power of having realized dynamic flexible between the communication system of at least two kinds of standards is shared.
The flow chart of the power sharing method that Fig. 8 provides for another embodiment of the present invention, as shown in the figure, the method comprises:
Wherein, priority can be definite according to the performance of communication system, and for example, the communication system of certain standard easily produces under powered problem, needs to be set to high priority, obtains shared power so that preferential; Or priority also can be definite according to the tendentiousness of operator, and for example, operator wishes preferentially to guarantee the normal operation of UMTS, can this system be set to high priority; Or according to the power demand of the communication system of these standards, power demand is larger, the priority of setting is higher.Certainly can also determine in other way the priority of communication system, the present embodiment does not limit this.
Described in the present embodiment, the power demand of method communication system of high priority in the communication system of each standard that shares same power amplifier surpasses default load thresholding, determine that between different systems communication system, carrying out power shares, and reduce the available horsepower of the communication system of low priority, thereby be conducive to guarantee that the communication system of high priority has enough available horsepowers.
