Description
Technical field
The present invention relates to wireless communication technology, relate in particular to a kind of authorization power acquisition methods, device and base station.
Background technology
High Speed Uplink Packet access (High Speed Uplink Packet Access; Referred to as: HSUPA) by adopting multi-code transmission, mixed automatic retransfer request (Hybrid Automatic RepeatRequest; Referred to as key technologies such as fast dispatch HARQ), based on base station (NodeB), greatly strengthen data service bearing capacity and the availability of frequency spectrum of up link.
Wherein, the fast dispatch based on NodeB mainly refers to that a scheduling of resource function is from radio network controller (Radio Network Controller; Referred to as: RNC) move down into NodeB, by NodeB based on current user equipment (User Equipment; Referred to as: channel condition UE) and user fairness are controlled the distribution of shared resource.The dispatch request information that NodeB reports according to UE, carries out resource distribution, and the resource of distributing comprises time slot, code channel and power mandate.In HSUPA, the information such as resource parameters, power that UE can authorize according to NodeB, and in conjunction with current each cell downlink code check scheduling indication information and remaining available horsepower information itself etc., its maximal rate is limited.For example, according to agreement regulation, timeslot number is 1 and 2 o'clock, and UE can send maximum transmission block (Transport Block; Referred to as TB piece) size is respectively 2720 and 5220, but because UE self has carried out code check restriction, sends maximum TB piece and may only have 2367 or 4650.
Wherein, in order to guarantee certain Block Error Rate, the larger desired power mandate of code check is larger, and for the UE that has code check restriction, power mandate there is no need to be greater than the needed mandate of UE maximal rate.But because NodeB cannot be known the maximal rate restricted information of UE, therefore, schedule information (the schedule information that NodeB reports according to UE; Referred to as: while SI) mandate, authorization power can be greater than the required power of UE maximal rate.When the power that licenses to UE as NodeB exceedes the required power of the maximal rate of UE, UE can adopt the transmitting power that maximal rate is corresponding to send upstream data with TB block size corresponding to maximal rate; It is inconsistent that now NodeB licenses to power and the actual emission power of UE, and NodeB, in the time carrying out power control, still estimates signal to noise ratio (the Signal to Noise Ratio of Pe-base according to authorization power; Referred to as: SNR), the SNR that NodeB side is estimated is less than actual SNR, and is less than SNR desired value, and therefore NodeB can constantly improve closed power component (Pe-base) by power control commands word by UE, causes power control to disperse.
Summary of the invention

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.Based on the embodiment 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.
The flow chart of the authorization power acquisition methods that Fig. 1 provides for the embodiment of the present invention one.As shown in Figure 1, the authorization power acquisition methods of the present embodiment comprises:
Wherein, E-PUCH is a uplink physical channel newly-increased in HSUPA technology, transmission strengthens dedicated channel, and (Enhanced Dedicated Channel, is called for short: E-DCH) the coded combination transmission channel of type (Coded Composite Transport Channel; Referred to as: CCTrCH), for carrying the upstream data of UE.Wherein, E-DCH has two medium access control (Media Access Control; Referred to as: MAC) sublayer: MAC-e and MAC-es.MAC-es, on MAC-e, directly receives MAC-es service data unit (Service Data Unit; Referred to as: (be SDU) MAC-d protocol Data Unit (Protocol Data Unit; Referred to as: PDU)).Wherein, formed objects and be multiplexed into a MAC-es PDU from the MAC-es SDU of same logic channel, multiple MAC-es PDU of multiple logic channels are multiplexed into a MAC-e PDU, and each transmission time gap (TransmissionTime Interval; Referred to as: TTI) can only send a MAC-e PDU.Whether concrete, UE sends data by E-PUCH to NodeB, and NodeB receives the data of UE, and obtain UE according to E-PUCH and also have data to send, and obtains the remaining data amount of UE.
Wherein, if when having enough remaining spaces in E-DCH transmission block or need to sending SI, can carry this SI by the afterbody of MAC-e PDU, therefore, UE can send SI to NodeB by E-PUCH timing, this SI is used for informing that whether NodeB also has data to send, and the data volume that waits to send is how many etc.In the present embodiment, NodeB obtains according to E-PUCH that the remaining data amount of UE specifically obtains according to the SI in E-PUCH.Because UE is that timing sends SI to NodeB, therefore, the current E-PUCH receiving of NodeB may comprise SI also may not comprise SI.Therefore,, in the time that NodeB receives E-PUCH, first judge whether this E-PUCH comprises SI; In the time judging this E-PUCH and comprise SI, NodeB is directly according to (the TotalE-DCH Buffer Status index of the E-DCH buffer status index value in SI; Referred to as: TEBS-index) obtain the remaining data amount of UE, TEBS-index represents data total amount waiting for transmission, i.e. remaining data amount on all E-DCH of the being mapped to logic channels of UE; In the time judging this E-PUCH and not comprising SI, NodeB obtains the SI finally receiving, obtain UE while finally receiving SI according to the TEBS-index in the SI finally receiving and wait the data volume sending, simultaneously NodeB is obtained from the data volume (i.e. the second data volume) that finally receives the UE that SI receives to current time, then, it is poor that NodeB UE when finally receiving SI waits the data volume and the second data volume that send, can obtain the remaining data amount of current time UE, UE waits the data volume sending.
Wherein, will send (the present embodiment is less than a MAC-d PDU as example take the remaining data amount of UE) during when UE does not have data, no matter whether NodeB licenses to UE power, no matter also NodeB licenses to the great power of UE and all there will not be the problem that exceedes maximal rate restriction that exists, therefore, the situation that does not have data to send for UE, the present embodiment does not limit the authorization power of NodeB, NodeB can adopt prior art scheme to carry out power mandate, for example, do not authorize or authorize a very little power to UE.
The present embodiment hypothesis UE has data to send, and the remaining data amount of UE is more than or equal to a MAC-d PDU, now, can continue to carry out subsequent step.
Wherein, before referring to this reception of NodeB E-PUCH, the first power power licenses to the power of UE, i.e. the authorization power corresponding to E-PUCH of this reception.The first data volume refers to the entrained data volume of E-PUCH channel that this is received.Wherein, NodeB, in the time receiving the E-PUCH of UE, can record and add up the data volume of the UE receiving.
Wherein, as authorization power (the Power Resource Related Information of NodeB; Referred to as: while PRRI) equaling the corresponding power of maximal rate of UE, when UE sends E-PUCH, required actual emission power is that closed power component (Pe-base) and the path loss calculation of safeguarding according to the authorization power of NodeB, UE side obtained.Wherein, in the time that the authorization power of NodeB is greater than the required power of UE maximal rate, UE can go out actual emission power according to the required power of maximal rate, closed power component and the path loss calculation safeguarded; The second authorization power corresponding to NodeB receives in this case the first data volume is likely inconsistent with the authorization power (i.e. the first authorization power) of NodeB.Wherein, the second authorization power refers to according to the corresponding relation between the authorization power of NodeB and authorization data amount, the required performance number of the first data volume calculating, that is calculate the required power of UE side maximal rate when actual emission power.
As the above analysis, the actual emission power of UE side is relevant with maximal rate, also can think relevant with data volume.Therefore, NodeB, by judging the magnitude relationship between the data volume (being authorization data amount) that data volume that E-PUCH is entrained and the first authorization power are corresponding, can know whether the first authorization power is greater than the required power of maximal rate while calculating actual emission power.
In the time that NodeB judges the first data volume and is less than authorization data amount, can know that when UE calculates actual emission power, the required power of maximal rate is less than the first authorization power, NodeB is according to the entrained data volume (i.e. the first data volume) of E-PUCH receiving, obtain the required power of UE side maximal rate, that is corresponding the second authorization power of the first data volume.Wherein, the second authorization power is corresponding to normalized gain factor-beta 0e, the method that NodeB calculates normalized gain factor-beta 0e is: NodeB obtains the actual data block size of carrying of E-PUCH (i.e. the first data volume) by decoding, and obtain corresponding code check according to data block size, then in rate tables, find the β 0e that this code check is corresponding, if this code check not in rate tables, needs to calculate by the mode of interpolation.Wherein, rate tables is configured by RNC and issues UE and NodeB by signaling.
Wherein, the 3rd authorization power refers to the authorization power after NodeB adjusts according to the required power of UE side maximal rate, need in subsequent power Authorized operation, license to the power of UE.Concrete, NodeB obtains the required power of UE side maximal rate (i.e. the second authorization power) afterwards, obtains the first authorization power thresholding according to formula (1); And in the first authorization power thresholding, obtain the 3rd authorization power.
MaxLemdGrant’＝(1-P)*MaxLemdGrant+P*L (1)
Wherein, MaxLemdGrant ' represents the first authorization power thresholding; MaxLemdGrant represents the second authorization power thresholding; L represents that NodeB calculates the required power of UE side maximal rate obtaining; P represents forgetting factor, and 0=< P <=1.Wherein, the first authorization power thresholding refers to the higher limit of the corresponding power of the 3rd authorization power; The second authorization power thresholding refers to the power upper limit value that the first authorization power is corresponding.
From above-mentioned formula (1), NodeB adjusts the power upper limit value that the first authorization power is corresponding (i.e. the second authorization power thresholding) according to the required power of UE side maximal rate, obtains the first authorization power thresholding; The required power of UE side maximal rate can further the higher limit of authorization power after adjusting by formula (1), and because the 3rd authorization power can not be greater than this first authorization power thresholding, the 3rd authorization power approaches the required power of UE side maximal rate more, has improved the accuracy of authorization power.
Further, from above-mentioned formula (1), along with the value of forgetting factor P is larger, the required power of UE side maximal rate is handed down to the 3rd authorization power of the UE impact of higher limit on NodeB is just larger, be that NodeB can adjust the required power of UE side maximal rate to being handed down to the influence degree of the 3rd authorization power of UE by adjusting the size of forgetting factor P, to take into full account required this factor of power of UE side maximal rate, improve the accuracy of the power that licenses to UE.
The authorization power acquisition methods of the present embodiment, NodeB knows that according to the E-PUCH of UE UE also has data to send, and estimate the required power of UE side maximal rate according to the entrained data volume of E-PUCH under the condition that has data to send at UE, according to the authorization power corresponding to E-PUCH of the required power of UE side maximal rate and this reception, obtain the follow-up power that should license to UE.Compared with prior art, the NodeB of the present embodiment obtains the required power of UE side maximal rate according to the data volume of the UE receiving, determine in conjunction with the rate that UE side maximal rate is required the power that licenses to UE, take into full account this factor of UE side maximal rate, therefore, improve the accuracy of the power that licenses to UE, overcome the problem because knowing that power control that the code check restricted information of UE causes is dispersed of NodeB in prior art.Further, because NodeB has improved the accuracy of authorization power, make UE can adopt suitable power to send data, avoid the power dissipation because adopting larger transmitting power to cause, reduce the interference of Liao Duizhe community or adjacent cell, reduce thermal noise lifting (the Rise OfThermal of Liao Duizhe community and adjacent cell; Referred to as: RoT).
The flow chart of the authorization power acquisition methods that Fig. 2 provides for the embodiment of the present invention two.The present embodiment can be realized based on embodiment mono-, and something in common repeats no more, and as shown in Figure 2, the authorization power acquisition methods of the present embodiment comprises:
Whether concrete, UE sends data by E-PUCH to NodeB, and NodeB receives the data of UE, and obtain UE according to the SI in E-PUCH and also have data to send, and obtains the remaining data amount of UE.
Wherein, the first data volume refers to the data volume that the E-PUCH of this reception of NodeB is entrained, the data volume corresponding to MAC-d PDU of carrying in MAC-e PDU.Be less than authorization data amount if judged result is the first data volume, illustrate that the required power of UE side maximal rate is less than the first authorization power of NodeB, execution step 24; Otherwise, if judged result is the first data volume while equaling authorization data amount, illustrate that the required power of UE side maximal rate equals the first authorization power of NodeB, performs step 25.
Step 24, obtain the second authorization power corresponding to the first data volume, and according to the first authorization power and the second authorization power, obtain the 3rd authorization power, and perform step 26;
In the time that NodeB knows that the required power of UE side maximal rate is less than NodeB that this E-PUCH receiving is corresponding and licenses to the power of UE, the data volume entrained according to the E-PUCH of this reception, obtain the required power of UE side maximal rate, then obtain according to formula (1) the first authorization power thresholding that the 3rd authorization power is corresponding, and in the first authorization power thresholding selection the 3rd authorization power.Concrete, NodeB can be as prior art according to UE dump power, remaining data amount and adjacent area disturbed condition etc. is selected to authorization power, then, the authorization power of selection and the first authorization power thresholding are compared, if be not more than the first authorization power thresholding, determine that selected authorization power is the 3rd authorization power; Otherwise, using the first mandate thresholding as the 3rd authorization power.
Step 25, the second authorization power thresholding is increased to default power step size value, and according to the second authorization power thresholding and default authorization power thresholding initial value, obtain the first authorization power thresholding, and perform step 26; Concrete, NodeB is known when the required power of UE side maximal rate equals to license to for the last time the power of UE (i.e. the first authorization power), the second corresponding the first authorization power authorization power thresholding is increased to default power step size value, to raise the second authorization power thresholding; Then, the second authorization power thresholding and default authorization power thresholding initial value after raising are compared; When the second authorization power thresholding after raising is less than default authorization power thresholding initial value, the second authorization power thresholding after raising is as the first authorization power thresholding; When the second authorization power thresholding after raising is more than or equal to default authorization power thresholding initial value, will preset authorization power thresholding initial value as the first authorization power thresholding.The first authorization power thresholding of NodeB based on now selected the 3rd authorization power.
Wherein, NodeB can set in advance authorization power thresholding initial value according to agreement regulation.Because agreement regulation represents authorization power with five bits, the scope of authorization power can only be-12 to 19 like this, and therefore, the present embodiment is in order to adapt with agreement, and the initial value of setting authorization power thresholding is 19.0dB, for the higher limit of initialization authorization power.
Wherein, from formula (1), NodeB only can lower authorization power thresholding in the time that the required power of UE side maximal rate is less than authorization power, so that the 3rd authorization power of selecting approaches the required power of UE side maximal rate as far as possible, and in order to prevent that authorization power thresholding from being lowered always, the present embodiment NodeB is by setting in advance power step size value, and in the time that the required power of UE side maximal rate equals the first authorization power, by this power step size value, authorization power thresholding is suitably raised, to guarantee that authorization power thresholding remains in proper range.Wherein, this power step size value can for set according to real network state, for example, can be made as 0.1dB, but be not limited to this.
Concrete, NodeB, after getting the 3rd authorization power that licenses to UE, can pass through E-DCH absolute grant channel (E-DCH Absolute Grant Channel; Referred to as: E-AGCH) the 3rd authorization power obtaining is handed down to UE in the time carrying out power Authorized operation, this E-AGCH can carry power authorization message (PRRI), comprises authorization power.
The authorization power acquisition methods of the present embodiment, NodeB knows that according to the E-PUCH of UE UE also has data to send, and estimate the required power of UE side maximal rate according to the entrained data volume of E-PUCH under the condition that has data to send at UE, according to the required power of UE side maximal rate and authorization power corresponding to this E-PUCH receiving, obtain the follow-up power that should license to UE, and in the time of subsequent power mandate, the 3rd authorization power obtaining is handed down to UE, so that UE sends follow-up data according to the 3rd authorization power.Compared with prior art, the NodeB of the present embodiment obtains the required power of UE side maximal rate according to the data volume of the UE receiving, determine in conjunction with the power that UE side maximal rate is required the power that licenses to UE, fully examine this factor of UE side maximal rate, therefore, improve the accuracy of the power that licenses to UE, overcome the problem because knowing that power control that the code check restricted information of UE causes is dispersed of NodeB in prior art.Further, because NodeB has improved the accuracy of authorization power, make UE can adopt suitable power to send data, avoid the power dissipation because adopting larger transmitting power to cause, reduce the interference of Liao Duizhe community or adjacent cell, reduce the RoT of Liao Duizhe community and adjacent cell.
