Description

The Poewr control method of Physical Uplink Control Channel and equipment

Technical field

The present invention relates to the field communication technical field, relate in particular to Poewr control method and the equipment of a kind of Physical Uplink Control Channel PUCCH.

Background technology

At LTE (Long Term Evolution; Long Term Evolution) in the technology; The reception condition of UE (User Equipment, subscriber equipment) feedback of down channel in PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel); Feeding back uplink ACK does not correctly receive then feeding back uplink NACK during correct the reception.ENB (eNodeB, base station) then can be to upstream data feeding back downlink ACK/NACK (being called for short A/N), and descending A/N is feedback in down channel PHICH (Physical Hybrid ARQ IndicatorChannel, Physical HARQ Indicator Channel).If up A/N or PHICH feedback are NACK, then eNB or UE can initiate corresponding retransmission, and this process is called HARQ (Hybrid AutomaticRepeat Request mixes automatic repeat requests).What the up A/N of LTE adopted is synchronous HARQ, promptly according to certain timing relationship feedback A/N and re-transmission, is asynchronous HARQ and descending PHICH adopts, promptly on the subframe of appointment, feeds back A/N.

Ascending HARQ course has certain timing relationship; Under FDD (Frequency Divided Duplex, FDD) scene, if UE receives downlink data in the N subframe; Then need be at N+4 subframe feedback A/N, if feedback is that NACK then eNB can retransmit in the N+8 subframe.TDD (Time Division Duplex, time division duplex) scene relative complex some because the ascending-descending subframes number of TDD system in a frame have different configurations; For example; Prior art can be supported the configuration of 7 kinds of ratio of uplink subframe to downlink subframe, and these 7 kinds of configurations are represented with 0-6 respectively, and are as shown in Figure 1.Concrete to adopt which kind of up and descending sub frame proportioning be that network passes through broadcast notice UE, and wherein D representes descending sub frame, and U representes sub-frame of uplink, and S representes special subframe.It is thus clear that in every kind of configuration, sub-frame of uplink is different with the ratio of descending sub frame.

The ascending HARQ timing relationship of TDD system does; If UE receives downlink data in the N subframe, then need be at N+k subframe feedback A/N, the value of k changes along with different configurations; Specifically as shown in Figure 2; The corresponding k value of each subframe of every kind of configuration reflects that in the drawings for example, the k value of the subframe 1 of configuration 1 is 6.Can calculate the subframe of the pairing feeding back uplink A/N of different descending sub frames numbering through such scheme.

In LTE-A (LTE-Advance, the evolution of LTE) technology,, carrier wave is converged (Component Aggregation, CA) technological method in order to support peak data rate as the expanding system bandwidth up to 1Gbits/s.It is that (Component Carrier CC) pools the carrier wave of a bigger bandwidth, to support the defeated rate of high-speed data with a plurality of composition carrier waves that carrier wave converges.System can dispose the main composition carrier wave of a pair of up-downgoing (PCC to UE; Primary Component Carrier; Be called for short main carrier), all the other carrier waves are auxilliary carrier wave (SCC, the Secondary Component Carrier of forming; Be called for short auxilliary carrier wave), main carrier and auxilliary carrier wave also can be called main plot (Pcell) and auxilliary sub-district (Scell) respectively.A kind of carrier dispatching technology of striding is proposed in the LTE-A technology; Promptly all send to the PDCCH of a plurality of carrier waves of scheduling UE on some or several carrier waves; Two CC have been configured such as UE; PCC and SCC, and the PDCCH (S-PDCCH) of the PDCCH (P-PDCCH) of scheduling PCC and scheduling SCC is placed on upward transmission of PCC.In the TDD system, only support the carrier aggregation of identical uplink-downlink configuration, can support the carrier aggregation of two uplink-downlink configuration 1, but do not support the carrier aggregation of uplink-downlink configuration 1 and configuration 2 such as R10.

For the TDD system; Different carrier possibly adopt different upstream and downstream subframe proportionings; As can adopt two carrier waves of configuration 1 and configuration 2 to carry out polymerization, if still keep the timing relationship of each carrier wave this moment, then may appear at the subframe moment that Scell needs feeding back uplink A/N; Pcell is descending sub frame at this moment, situation about can't normally feed back possibly occur.A kind of solution that prior art proposes is the timing relationship feedback that only keeps Pcell, and the A/N that promptly the subframe n of Pcell is corresponding is regularly constant, and the timing relationship of Scell needs to revise.If the subframe n of Scell is corresponding on Pcell according to the sub-frame of uplink of former timing relation feedback also to be sub-frame of uplink, then can on Pcell, feed back according to the timing relationship on the former Scell; If the subframe n of Scell is not a sub-frame of uplink according to sub-frame of uplink correspondence on Pcell of former timing relation feedback; Then need the corresponding A/N feedback of new this sub-frame of design n regularly; For example; Can find Pcell to go up the corresponding subframe n+k of sub-frame of uplink according to former timing relation feedback with subframe n, select the sub-frame of uplink of the Pcell minimum with respect to subframe n+k time delay to feed back, the next nearest sub-frame of uplink of promptly waiting until subframe n+k among the Pcell is as the feedback subframe.That is to say that what above-mentioned feedback adopted is asynchronous A/N feedback.Because uplink synchronous HARQ timing relationship is revised as asynchronous HARQ timing relationship, thereby the A/N bit number of adjacent sub-frame of uplink feedback possibly have bigger difference, and this transmitting power control for PUCCH can cause bigger influence.The power control formula of PUCCH is:

P _PUCCH(i)＝min{P _CMAX，P _{0_PUCCH}+PL+h(n _CQI，n _HARQ)+Δ _{F_PUCCH}(F)+g(i)}[dBm]

P wherein _PUCCH(i) the PUCCH channel transmitting power on the expression subframe i, P _CMAX=min (P _EMAX, P _UMAX) expression UE actual emission power, get less that in the maximum power transmission ability (by the grade class decision of UE) of UE and the maximum transmission power that network side issues, P _{0_PUCCH}Expression PUCCH channel open loop power, PL (Path Loss) representes path loss, Δ _{F_PUCCH}(F) expression is the compensation to different PUCCH format (form), and g (i) representes dynamic deflection, h (n _CQI, n _HARQ) be to identical PUCCH format (form) compensation of different UCI (ascending control information) bit number down, n _CQIBe the bit number of CQI, n _HARQIt is the bit number of HARQ.

And in the prior art, adopt TPC (Transmit Power Control, through-put power control) dynamic range to carry out the calculating of PUCCH transmitting power.For example; In the TPC of existing DL grant (comprising DCIFormat 1/1A/1B/1D/2/2A) or DCI Format 3; Available 2bits indication information indication UE carries out the power adjustment; Indication information can be indicated [1013] four values, is respectively applied for the adjusted value of expression power, has 1bit TPC to can be used for indication [11] two power adjustment among the DCI Format 3A.Such as, when indication information was shown as 1, UE will have PUCCH power now increased 1dB; When indication information is shown as-1, UE will have PUCCH power now and reduce 1dB.And the variation of the PUCCH transmitting power that A/N bit number difference causes may exceed the dynamic power control scope of TPC, thereby the PUCCH transmitting power that calculates may occur than big-difference, and accuracy is not enough.

Embodiment

To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.

Carry out feeding back ACK/NACK at subscriber equipment and (correctly receive message/non-correct reception message; Be called for short A/N) when giving its services sites-like the base station; The feedback desired power maybe be different on different subframes, mention like background technology, the variation of this power demand maybe the time since the bit number of feeding back ACK/NACK change and cause; In order to overcome this problem, the embodiment of the invention provides a solution.The sketch map of the Poewr control method of a kind of PUCCH that Fig. 3 provides for embodiments of the invention, this method comprises:

S31: a plurality of sub-frame of uplink are classified obtains at least one sub-frame groups, in said at least one sub-frame groups in each subframe group on the sub-frame of uplink bit number of feeding back ACK/NACK belong to one section preset range respectively.

UE can classify based on the bit number of feeding back ACK/NACK to its a plurality of sub-frame of uplink.UE can store the PUCCH power control parameters of many groups; The approaching sub-frame of uplink of A/N bit number that every group of parameter is corresponding one type; Can classify to sub-frame of uplink based on said parameter like this, make each divide the bit number of the subframe in the group to belong to one section preset range separately.A sub-frame sketch map as shown in Figure 4, as to provide for the embodiment of the invention.This 6 sub-frame of #2, #3, #4, #7, #8 and #9 is a sub-frame of uplink, and all the other 4 sub-frame are descending sub frame, can specifically be divided into the n class according to the A/N bit number carrying out the branch time-like.In the present embodiment, the scope of the bit number of feedback A/N can be divided into 4 types, and each type scope is respectively: [0,5], [6,10], [11,15], [16,20].The bit number of confirming the A/N of each sub-frame of uplink feedback is positioned at above-mentioned which hop count value scope, and the pairing subframe of A/N bit number that will be positioned at same hop count value scope is divided into a group.The A/N bit number of supposing #2, #3, #7 and #8 work song frame belongs to same type of more approaching subframe of A/N bit number in [16,20] scope, then can be in same group 1; And the A/N bit number of #4 and #9 work song frame belongs to same type of more approaching subframe of A/N bit number in [11,15] scope, then divides in another group 2.Certainly present embodiment be not used in qualification the present invention for example, a plurality of sub-frame of uplink are being carried out the branch time-like based on the A/N bit number, the quantity of the group of being divided can be adjusted according to the actual requirements.Usually in using, subframe can be divided in a plurality of groups according to said method, but under a particular case, if the A/N bit number that feeds back on all a plurality of subframes is more or less the same, all drops in the same hop count value scope, then also can a plurality of subframes be divided in a group.The number range that is used to divide into groups can preestablish, and also can be changed according to application demand by those skilled in the art, and present embodiment is not done qualification to this.

S32: the transmitting power according to the PUCCH of other sub-frame of uplink in the subframe group of current sub-frame of uplink place is carried out through-put power control to said current sub-frame of uplink.

Because the many groups of UE storage PUCCH power control parameters, when carrying out power calculation, but the uplink transmission power of interior other subframe of subframe reference group is carried out TPC in each group.It still is example with Fig. 4; Grouping before supposing is constant; Calculating for the PUCCH transmitting power of #9 work song frame can be with reference to the PUCCH power of #4 work song frame in this frame on the same group, calculates the PUCCH power with reference to #8 work song frame in the previous frame on the same group for the PUCCH transmitting power of #2 work song frame.Be appreciated that owing to comprise a plurality of frames on the time domain 10 sub-frame are arranged in each frame, for present frame, if can not find in the present frame can reference sub-frame of uplink, can look for the sub-frame of uplink in the frame forward.

In embodiments of the present invention; If the less sub-frame of uplink of A/N bit number difference is divided into one type; Then just have certain reference value between the PUCCH power of similar sub-frame of uplink, can carry out the dynamic power adjustment, thereby reduce the transmitting power difference of different subframes; Adjustment amount exceeds the situation of the dynamic power control scope of TPC when reducing power control, and the PUCCH transmitting power that makes acquisition more accurately and reliably.

For the ease of carrying out the control of sub-frame of uplink transmitting power; When different sub-frame of uplink transmit power variation are bigger, TPC dynamically adjustment is inaccurate, can let UE through recomputating the PUCCH transmitting power; UE can be recomputated under the opportunity that is fit to; And under other scenes, only carry out TPC, this just needs the notice of base station, makes UE determine whether to recomputate according to the power control formula of PUCCH the transmitting power of PUCCH according to notice.Fig. 5 a is the sketch map of the Poewr control method of the another kind of PUCCH that provides of embodiments of the invention, and this method comprises:

S51a: generate physical downlink control channel PDCCH message;

S52a: send said PDCCH message and give subscriber equipment, whether recomputate the transmitting power of the PUCCH of current sub-frame of uplink with notifying user equipment.

Said process is the process that the base station generates and sends PDCCH message, and UE can carry out corresponding therewith operation, and the base station can be in due course according to self-demand and notify UE to carry out said operation.Fig. 5 b is the sketch map of the Poewr control method of the another kind of PUCCH that provides of embodiments of the invention, and this method comprises:

S51b: receive physical downlink control channel PDCCH message;

S52b: the transmitting power that determines whether to recomputate the PUCCH of current sub-frame of uplink according to said PDCCH message.

Concrete; Said PDCCH message can be downstream grants signaling DL grant; Comprise DCI Format1/1A/1B/1D/2/2A; Said DL grant calculates as the transmitting power that a kind of descending control signaling can be used for notifying UE to carry out PUCCH again on suitable opportunity, rather than carries out the TPC adjustment based on the transmitting power of previous moment or subframe.

In a kind of application, specifically newly-increased indicating bit in said DL grant is used to indicate subscriber equipment whether to recomputate the transmitting power of the PUCCH of current sub-frame of uplink.If newly-increased indicating bit is that the base station is set to first preset value, when for example being 1 (True), can indicate UE to recomputate the transmitting power of PUCCH according to the power control formula of PUCCH; If newly-increased indicating bit is that the base station is set to second preset value, during like 0 (False), then change the method that indicating bit indication UE adopts dynamic power control, only the transmitting power based on the PUCCH of a nearest sub-frame of uplink increases a TPC value.

In another kind was used, the specific fields of base station in can said DL grant was set to redundant state, and the indication subscriber equipment recomputates the transmitting power of the PUCCH of current sub-frame of uplink.When said specific fields is set to the nonredundancy state, then indicate subscriber equipment to carry out the through-put power control of current sub-frame of uplink based on the transmitting power of the PUCCH of previous sub-frame of uplink.For example, some fields in descending control signaling can be used for realizing said function like MCS (Modulation and Coding Scheme, Modulation and Coding Scheme) field.Such as; 29,30,31 totally 3 redundant states are arranged in the MCS field of 5bits; So-called redundant state is meant disarmed state, if promptly the MCS field is represented this 3 kinds of redundant states, it is not used in the MCS that indicates MCS to indicate in other words is invalid; When only other under the nonredundancy state was worth, this field was just indicated a kind of effective MCS.When the MCS field was changed to redundant state, UE recomputated the transmitting power of PUCCH according to the power control formula of PUCCH, and the MCS that needs to use is with reference to history value.

In said process, the redundant state of a specific fields is used to indicate UE to carry out the power of transmitting power re-computation before also being based on to carry out the TPC adjustment.This moment, specific fields can not be used to indicate original specific function, and this moment, function of its original indication can not be implemented again, and the numerical value of indication that originally need be through this specific fields can be with reference to the previous value that is set to this specific fields of nonredundancy state.Be the example explanation still with the MCS field; What in a Downlink Control Information, find MCS field indication as UE is invalid state; Then recomputate the transmitting power of the PUCCH of the current sub-frame of uplink that will send data; But the MCS field will no longer have the MCS deixis, and the MCS of this moment needs the indicated MCS value of effective MCS field with reference to last reception, thereby can guarantee up normal transmission.

In another kind was used, the through-put power control field of the PDCCH message that send the base station can be set as null value, is used to indicate the transmitting power of the PUCCH that recomputates current sub-frame of uplink; If said through-put power control field is set as nonzero value, then carry out the TPC control procedure, promptly the transmitting power based on the PUCCH of a nearest sub-frame of uplink increases the corresponding TPC value of said field.

When different sub-frame of uplink transmitting powers there are differences or differ greatly, in order to keep the validity of TPC, a feasible way was exactly to reset the dynamic range of TPC, made TPC can be used to indicate bigger adjusting range.The sketch map of the Poewr control method of the another kind of PUCCH that Fig. 6 provides for embodiments of the invention, this method comprises:

S61: generate the physical downlink control channel PDCCH message that comprises the through-put power control field, said through-put power control field is used to indicate the through-put power control dynamic range that enlarges with respect to existing through-put power control dynamic range;

S62: send said PDCCH message to subscriber equipment, utilize the through-put power control dynamic range of said expansion to carry out the through-put power control of current sub-frame of uplink with notifying user equipment.

In response to the PDCCH message that send the base station, UE can carry out corresponding control action.The sketch map of the Poewr control method of the another kind of PUCCH that Fig. 7 provides for embodiments of the invention, this method comprises:

S71: receive the physical downlink control channel PDCCH message that comprises the through-put power control field, said through-put power control field is used to indicate the through-put power control dynamic range that enlarges with respect to existing through-put power control dynamic range;

S72: utilize the through-put power control dynamic range of said expansion to carry out the through-put power control of current sub-frame of uplink.

In a kind of concrete realization, the adjusted value of said through-put power control field indication can be set to the adjusted value greater than existing through-put power control field indication, thereby realizes bigger TPC scope.In this application, can not change the bit of TPC field, just simple with present TPC expanded range.As the 2bits TPC scope among DL grant or the DCI Format 3 is revised as [3035] by original [1013], perhaps the 1bit TPC scope among the DCI Format 3A is revised as [33] by original [11].

In another kind is used, can on existing through-put power control field, increase one or several bits and obtain the new through-put power control field of stating, make said through-put power control field indicate more a plurality of adjusted values than existing through-put power control field.As the 2bits TPC among DL grant or the DCI Format 3 is expanded to 3bits, the adjusting range that degree is answered is revised as [3-10135] by original [1013], can represent more dynamically adjusted value like this, carries out power more neatly and dynamically adjusts.

Particularly; When the through-put power control dynamic range that indication enlarges, can increase the dynamic range of several groups of TPC, as increasing [3035], [2024] etc. more; Make a same TPC value can be used to indicate multiple different scope; For example, be that the 2bits indication field was shown as 10 o'clock equally, can under different configurations, indicate different TPC values.Which group is the dynamic range that will have many group TPC this moment specifically use to make an appointment or to use signaling UE to adopt which group in many group through-put power control dynamic ranges.For a certain type of UE that satisfies the condition of making an appointment, it need not notified and can learn, which group through-put power control dynamic range this UE can use by appointment.Be explained for example; If there are three groups of dynamic ranges in TPC; Be respectively [1013], [3035], [2024], wherein [1013] are original scope, [3035], [2024] scope for enlarging; Promptly for same TPC indicated value, the adjusting range of the two groups of dynamic range indications in back is bigger.The base station need agreement be certain regular in advance with UE, such as the scope [3035] that when channel quality satisfies certain condition, can adopt the 2nd group to enlarge, makes the amplitude of TPC adjustment increase; And do not satisfying said certain condition or when channel quality reaches other certain condition, can only adopt normal adjusting range [1013].Certainly, specifically adopt which class range can pass through RRC (Radio Resource control) signaling UE by the base station as the value of adjustment, present embodiment is not done qualification to this yet.Present embodiment can enlarge the amplitude of TPC adjustment through said process, need make under the situation of bigger adjustment at the PUCCH of sub-frame of uplink power, can increase adjusting range, reduces the situation generation that adjusted value possibly exceed the dynamic power control scope of TPC.

The embodiment of the invention also provides a kind of method, when the transmitting power adjusting range of sub-frame of uplink is big, can in the power control formula, increase a correction term delta h with compensation owing to transmit power variation.The sketch map of the Poewr control method of the another kind of PUCCH that Fig. 8 provides for embodiments of the invention, this method comprises:

S81: the transmitting power of PUCCH of obtaining two sub-frame of uplink is poor;

Particularly, UE can calculate, and promptly according to bit number poor of feeding back ACK/NACK on two sub-frame of uplink, confirms that the transmitting power of PUCCH of said two sub-frame of uplink is poor.UE can be specifically through calculating the h (n in the PUCCH power control formula _CQI, n _HARQ) item obtains the difference of the PUCCH transmitting power of different subframes under the influence of the different A/N bit number of feedback.For example, can be with the h (n of two sub-frame _CQI, n _HARQ) difference of function is as delta_h, also can do further processing so that carry out more fine compensation to said difference, present embodiment is not done qualification to this.

Certainly, it is poor that UE also can obtain the transmitting power of PUCCH of two sub-frame of uplink according to the notice of base station, and said notice can adopt physical layer signaling to realize.For example can confirm said transmit power differences according to the indication of newly-increased indicating bit among the said DL grant through receiving the DL grant message that send the base station.In addition, the specific fields among the said DL grant can be set to redundant state by the base station, and this moment, UE can confirm said transmit power differences according to the indication of said redundant state.

S82: according to the transmitting power of the PUCCH of first sub-frame of uplink in two sub-frame of uplink, second sub-frame of uplink in two sub-frame of uplink is carried out through-put power control, obtain the transmitting power of initial p UCCH.

S83: utilize the transmitting power difference of the PUCCH of said two sub-frame of uplink to compensate the transmitting power of said initial p UCCH, obtain the transmitting power of the PUCCH of second sub-frame of uplink.

In the present embodiment; When UE variant at the bit number of feedback A/N on some subframe with the number of bits of feedback on before the subframe; Can confirm that the transmitting power of PUCCH of different subframes is poor based on the bit number difference of needs feedbacks; Thereby utilize these differences to compensate TPC adjustment result, make that the result of TPC control is more accurate.For example carry out TPC control according to prior art when the base station; TPC indication adjustment power increases 1dB; The transmitting power that then on last subframe transmitting power basis, increases 1dB is as Initial Trans, and further utilizes said transmitting power difference to compensate on this basis.Such as; If the transmitting power difference that calculates based on the bit number difference of two sub-frame feedbacks A/N is 1dB; Then also need on the Initial Trans basis, increase 1dB, obtain the transmitting power that current subframe really need be used, thereby increase the order of accuarcy of confirming the PUCCH transmitting power.
