Description

Power headroom reporting method, base station and subscriber equipment

Technical field

The present invention relates to the wireless technology transmission field, be specifically related to a kind of power headroom reporting method, base station and subscriber equipment.

Background technology

Because individual or mobile communication equipment have required to have the ability of broadband business such as multimedia service, game on line, video request program and mobile TV, wideer band system band, higher peak rate and better edge service quality have become an important need of following individual or mobile communication system.3GPP (3G (Third Generation) Moblie partner plan) tissue is as the international organization that is devoted to individual or mobile communication standard work, design EUTRA (universal mobile telecommunications system of evolution and continental rise radio insert) and EUTRAN (the universal mobile telecommunications system net of evolution and continental rise radio access network) since the second half year in 2004, this project is also referred to as LTE (Long Term Evolution) project.In April, 2008,3GPP is organized in the China Shenzhen meeting, begin to inquire into the standardization effort of the 4th generation (4G) cellular communication system, 3GPP tissue definition LTE-Advanced (LTE-A) is as the version that carries out evolution to following 4G version from present 3GPP LTE 8.0 versions for this reason, and at Shenzhen session discussing the demand of LTE-A and possible correlation technique motion.In this meeting, many companies have proposed the frequency band problem of LTE-A system and the rendezvous problem of frequency spectrum.After discussing and conferring, the chairman has submitted LTE-A demand draft to, (REV-080058, Draft LTE-AdvancedRequirements), spell out the LTE-A system in this draft and need support the band system band of maximum 100MHz, frequency band for the 100MHz system can be one section continuous carrier wave frequency range, also can assemble (CA by the discrete carrier wave frequency range of multistage being carried out carrier wave, carrieraggregation) obtain, it is exactly a plurality of continuous or discrete carrier wave frequency range (CC of unit that carrier wave is assembled, component carrier) form a wideer frequency range, for example the CC of 5 20MHz can form the frequency range of 1 100MHz.Draft points out also that simultaneously LTE (LTE Release-8.0) system and LTE-A system can coexist on same frequency spectrum, that is to say that the LTE-A system needs the subscriber equipment of forward compatibility LTE.The frequency band of LTE system is designed to maximum 20MHz, the maximum band ability of LTE subscriber equipment also is 20MHz, LTE-A system by 100MHz is had only the LTE subscriber equipment of 20MHz ability that compatible services is provided, this has proposed challenge for design of LTE-A system, especially at aspects such as the design of frequency band division, broadcast channel and synchronization channel design, system's control signaling, uplink power control, carrier dispatching modes.

Power control about the LTE-A system, because LTE system up-link (UL, uplink) adopt the multiplexing (SC-FDMA of single carrier frequency division, single carrier frequency divisionmultiplex acess) technology, different user devices (UE in the sub-district, user equippment) be mutually orthogonal between the upward signal, therefore, system that the up link nonexistent code of LTE-A system divides multiplexing (CDMA, code division multiplex acess) carries out the necessity of power control because of near-far interference.LTE uplink power control (UL PC, uplink power control) is mainly used in the path loss and the shadow fading of compensate for channel, and is used to suppress presence of intercell interference.The power control of LTE system does not need to adopt cdma system fast frequency like that, and adopt the mode of slow power control to get final product, and up link can be respectively to Physical Uplink Shared Channel (PUSCH, physical uplink share channel), Physical Uplink Control Channel (PUCCH, physicaluplink control channel) and uplink detection reference signal (SRS, soundingreference signal) channel transmitting power control.

In LTE (LTE Release-8.0) system, the power of the up link of PUSCH is controlled as shown in Equation (1),

P _PUSCH(i)＝min{P _CMAX，

(1)

10log ₁₀(M _PUSCH(i))+P _{O_PUSCH}(j)+α(j)·PL+Δ _TF(i)+f(i)}

Wherein, i is the call number of subframe (sub-frame), P _PUSCH(i) be the uplink transmission power of UE on PUSCH, P _CMAX(i) be the maximum transmission power of UE, M _PUSCH(i) for distributing to the quantity of ascending resource piece (RB, resource block) of this UE, j is the call number of carrier wave frequency range and is the value of immobilizing, P in the LTE system _{O_PUSCH}(j) be the parameter (comprising target SINR, interference level etc.) that the sub-district is specific or UE is specific, α (j) is the specific path loss penalty coefficient (amplitude that depends on " control of part power " in sub-district, α (j) 1 promptly carries out completely the path loss compensation), PL is the path loss (PL of the down link that measures of UE, pathloss) value, Δ _TF(i) be Radio Resource control (RRC, radio resource control) the specific modulation encoding scheme (MCS of layer appointment, modulation and coding scheme) parameter, be that MCS gives the indication in (ULresource grant) information at ascending resource, f (i) is the function of closed power control command.

In the LTE system, the power of the up link of PUCCH is controlled as shown in Equation (2),

P _PUCCH(i)＝min{P _CMAX，

(2)

P _{O_PUCCH}+PL+h(n _CQI，n _HARQ)+Δ _{TF_PUCCH}(F)+g(i)}

Wherein, i is the call number of subframe (sub-frame), P _PUCCH(i) be the uplink transmission power of UE on PUCCH, P _CMAX(i) be the maximum transmission power of UE, P _{O_PUCCH}The parameter (comprising target SINR, interference level etc.) specific for the sub-district or UE is specific, PL is downlink path loss (PL, pathloss) value, the h (n that UE measures _CQI, n _HARQ) be the peculiar functional value of PUCCH, the n here _CQIBe bit (bit) number that is used for channel quality indication (CQI, channel quality indicator), n _HARQBe the bit number that is used to mix automatic repeat requests (HARQ, hybrid automaticrepeat-request), Δ _{F_PUCCH}(F) be based on the corrected value of UE, g (i) is used to represent that current PUCCH power adjusts the functional value of state, and is the function of transmitting power control (TPC, the transmit power control) instruction of PUCCH.

In the LTE system, the power of the up link of SRS is controlled as shown in Equation (3),

P _SRS(i)min{P _CMAX，

(3)

P _{SRS_OFFSET}+10log ₁₀M _SRS)+P _{O_PUSCH}(j)+α(j)·PL+f(i)}

Wherein, i is the call number of subframe (sub-frame), P _SRS(i) be the uplink transmission power of UE on SRS, P _CMAX(i) be the maximum transmission power of UE, P _{SRS_OFFSET}Be the parameter of representing the semi-static control of high-level signaling with 4 bits based on UE, M _SRS(i) be the quantity of distributing to the ascending resource piece that is used for transmitting SRS (RB, resource block) of this UE, P _{O_PUSCH}(j), the definition of α (j), f (i) is identical with the definition in the formula (1).Therefore, the control of the power of uplink SRS can be corresponding with up PUSCH power control, and only there is a fixing deviant in both.

In the uplink power control of UE, in order to make base station (BS, base-station) can provide suitable up closed-loop control instruction to each UE, UE need measure and report the power rising space (PH of oneself, power headroom), it is power headroom, the maximum transmission power of definable UE deducts the difference of UE after by power control emitted power value, then, BS carries out ascending resource scheduling (UL resource scheduling) according to the PH of UE report, the schedule information of ascending resource scheduling decision UE, schedule information comprises number and the position in sub-frame of uplink (sub-frame) thereof of up RB, up MCS mode (comprises modulation system, coded system), uplink transmission block (TB, tranmission block) size etc., then, BS is by Physical Downlink Control Channel (PDCCH, physical downlingk control channel) the transmission ascending resource is given (UL Grant, uplink resource grant) signal is given UE, UE detects the UL Grant information on the PDCCH channel and obtains uplink scheduling information, power control formula (1) according to PUSCH carries out the power adjustment of upstream data again, and sends upstream data with adjusted power.And, consider in LTE Release-8.0 system, same UE transmits the data (Data) of PUSCH or the control signaling (Controlsignaling) of transmission PUCCH in a subframe, do not take place and do not exist simultaneously in PUSCH transmission data with in the situation of PUCCH control channel, therefore, power headroom reporting (PHR, power headroom reporting) only is defined in the power control process of PUSCH.UE goes up pH value to BS report PUSCH, BS carries out scheduling of resource according to pH value, the number that distributes up RB Resource Block, position in subframe, uplink scheduling informations such as the coded system of up PUSCH data and modulation system, BS passes to UE to uplink scheduling information by the PDCCH channel with the ULgrant signaling, UE carries out sending data to BS after the PUSCH uplink power control according to formula (1), at this, because same UE can not send data and control signaling simultaneously respectively on PUSCH and PUCCH, therefore, upstream control signaling only need carry out the power control of up PUCCH according to formula (2), UE need more or not define the trigger event of the PHR of PUCCH to BS report pH value on PUCCH in LTE Release-8.0 system, corresponding triggering timer and corresponding PHR mechanism.Then, consider that the LTE-A system is the frequency lens system of many CC, for improving the performance of LTE-A system, the LTE-A system allows UE to send data and control signaling respectively in same subframe on PUSCH and PUCCH simultaneously, therefore, UE must carry out the uplink power control of PUSCH and PUCCH simultaneously respectively, might have two kinds of situations this moment occurs: one, if the transmitted power of UE is unrestricted, such as the central authorities of UE at wireless area, channel condition information (the CSI of up channel, channel stateinformation) more satisfactory, UE can freely carry out the uplink power control of PUSCH and PUCCH respectively, and the order (Rank) that UE can pass through Uplink MIMO (MIMO, multiple input multipleoutput) is more than or equal to 3 high-order mode transmit ascending data; They are two years old, if the transmitted power of UE is restricted, such as the edge of UE at wireless area, channel condition information (the CSI of up channel, channel state information) poor, UE can not freely carry out the uplink power control of PUSCH and PUCCH respectively, UE is used for PUSCH and PUCCH power all to be subjected to the restriction of the limited maximum transmission power of UE and to influence each other, therefore, the order (Rank) that UE can only adopt Uplink MIMO is smaller or equal to 2 low order mode transmit ascending data, at this, because UE can not carry out the uplink power control process of PUSCH and PUCCH respectively, UE can't carry out the report of pH value accurately, if only carry out the report of the PH of PUSCH, so the LTE-A system must define PH and the corresponding PHR trigger event of PUCCH, trigger timer and trigger mechanism.

Ascending power control method as previously described LTE-A system, because down link and up link have all been introduced the mechanism of a plurality of CC, therefore, LTE-A system decision is all adopted (CC-specific) mode based on CC in the uplink power control mode of up PUSCH, PUCCH and SRS.And, can find that by formula (1), (2), (3) uplink power control all needs the path loss (DL pathloss) of down link is measured, the downlink path loss then comprises the path loss of a plurality of CC in the LTE-A system, therefore, there is company to propose to measure the path loss of a DL CC among a plurality of DL CC in the 59th meeting of LTE RAN1, calculates the path loss that can be used in formula (1), (2), (3) by backoff algorithm.In addition, although the LTE-A system has the ability that inserts a plurality of DL CC, but when downlink traffic has in limited time, only one or several just can satisfy the demand of downlink transfer traffic carrying capacity among the whole descending CC of needs access, therefore, down link must adopt DL CC dispatching technique, promptly selects one or several in a plurality of DL CC and is used for downlink transfer.Up to the present, in supporting the LTE-A system that carrier wave is assembled, can be divided into two kinds: with carrier dispatching with stride carrier dispatching about the carrier dispatching mode of LTE-A system.The former be meant a PDCCH scheduling on the descending carrier with the PDSCH on the carrier wave or with the up-link carrier of this carrier wave pairing on PUSCH; The latter be meant on PDCCH scheduling on descending carrier descending carrier different with this PDCCH place carrier wave PDSCH or with the up-link carrier of this PDCCH place carrier wave non-matching on PUSCH.For striding carrier dispatching, when the PCFICH on the carrier wave of PDSCH place (physical format indicating channel) occurs detecting mistake, subscriber equipment can't obtain correct PDSCH starting position, thereby cause subscriber equipment to store wrong data in the HARQ buffer memory and feed back NACK.This PCFICH flase drop problem can't itself be solved by HARQ mechanism, can only solve by wireless chain control layer.With also there being this problem in the carrier dispatching, still owing to PDCCH and PCFICH are in same descending carrier at this moment, the parsing of PDCCH will offer the error detection that PCFICH detects many one decks, so the likelihood ratio that PCFICH flase drop problem takes place is less.PCFICH probability of false detection when striding carrier dispatching in the LTE-A system in order to make be consistent with carrier dispatching, need research to reduce the method for the PCFICH probability of false detection when striding carrier dispatching.

The present invention finds report (PHR, power headroom reporting) and carrier dispatching mode at the power rising space of cellular system by investigation and analysis to the prior art document, and existing method is as follows:

(1) the PHR mechanism of LTE Release-8.0

In LTE Release-8.0 system, the purpose of report PH is that the difference of the estimating power of nominal maximum transmission power of UE and PUSCH channel is offered BS.The PH of UE defines as shown in Equation (4),

PH(i)＝P _CMAX-

(4)

{10log ₁₀(M _PUSCH(i))+P _{O_PUSCH}(j)+α(j)·PL+Δ _TF(i)+f(i)}

Wherein, i represents the call number of subframe, P _CMAX, M _PUSCH(i), P _{O_PUSCH}(j), α (j), PL, Δ _TF(i) identical with the definition in the formula (1) with the definition of f (i), the value of the power rising space should drop in the interval of [40 ,-23] dB, and PH should transmit to high-rise (higher layer) from physical (L1).Rrc layer is by configuration (configure) two timers, i.e. PHR timer (periodicPHR-Timer) and forbid PHR timer (prohibitPHR-Timer) periodically, control PHR, and rrc layer also can trigger timer by change (DL-PathlossChange) value that the downlink path loss is set.PHR can be by following Event triggered:

1. prohibitPHR-Timer then or then, the change of path loss surpasses DL-PathlossChange value (dB), and when UE had new ascending resource to send, UE carried out PHR; Perhaps

2. periodicPHR-Timer then.

Upper strata (upper layer) disposes (configure) or reconfigures (reconfigure) controls PHR.Referring to document 3GPP TS 36.213 V8.8.0, in September, 2009; 3GPP TS36.321 V8.8.0, in December, 2009.

But, as mentioned above, the PHR mechanism of LTE Release-8.0 system does not consider that same UE transmits data and the situation of controlling signaling at PUSCH and PUCCH respectively simultaneously in same subframe, UE sends the control signaling of PUCCH simultaneously and needs the situation of the transmitted power of a plurality of CC of distribution at (CC) of a plurality of up-link carrier frequency ranges when also considering the transmit power limited as UE, though these situations do not occur in LTE Release-8.0 system, can in the LTE-A system, occur.

(2) the PHR mechanism of CATT

Datang Telecom (CATT) and some other company not only exist PUSCH to send data conditions separately at the system of LTE-A, and may exist the while to send the situation of data and signaling respectively at PUSCH channel and PUCCH channel, propose LTE-A and need define two kinds of PHR mechanism: one, when having only PUSCH to send data, define a kind of PHR mechanism, as shown in Equation (5); Its two, respectively when PUSCH channel and PUCCH channel send data and signaling, define another kind of PHR mechanism, as shown in Equation (6) simultaneously.

PH(i)＝P _CMAX-P _PUSCH(i) (5)

PH(i)＝P _CMAX-P _PUSCH(i)-P _PUCCH(i) (6)

Wherein, i, P _CMAXDefinition can be referring to formula (1)～(4), P _PUSCH(i) definition can be referring to formula (1), P _PUCCH(i) definition can be referring to formula (2).Referring to document: 3GPP LTE motion R1-100071, CATT, " Considerations on uplink power control inLTE-Advanced ", 3GPP TSG RAN WG1 meeting #59bis, Valencia, Spain, 18 ^Th-22 ^NdJanuary 2010.

But this scheme needs UE to send 1 bit signalling to inform that BS distinguishes UE and adopts any in above-mentioned two kinds of PHR mechanism; This scheme can't solve situation about sending control signaling simultaneously on the PUCCH of a plurality of up CC, promptly when the power limited system of UE, UE can't carry out the transmit power assignment of each CC at a plurality of up CC.Therefore, the PHR method of CATT can not satisfy the demand of LTE-A to PHR fully.

(3) the PHR mechanism of Ericsson

Ericsson (Ericsson) and some other company proposed in the characteristics of transmitting on the PUSCH/PUCCH at the many UL CC and the while of LTE-A system: under the situation of UE power limited system, if the LTE-A system allows UE to send data and control signaling simultaneously respectively on PUSCH and PUCCH, so, the LTE-A system should possess the ability of PUSCH channel and PUCCH Channel Sharing transmitted power separately of allowing, since PUCCH has independently power control mechanism, if BS do not know PUCCH consume/will consume how much power, so, BS also can't know the transmission of the PUSCH also remaining how much power of UE can be used for being scheduled, therefore, PH should definition respectively in the power control process of PUCCH and PUSCH.Referring to document: 3GPP LTE motion R1-100045, Ericsson, ST-Ericsson, " Uplink Power Control for Carrier Aggregation ", 3GPP TSG RAN WG1 meeting #59bis, Valencia, Spain, 18 ^Th-22 ^NdJanuary2010.

But, this method does not point out that there be Reporting a Problem of PH too in the LTE-A system when existing a plurality of up CC to be used for the PUCCH transmission, it is the power limited of UE, but UE must send the control signaling of PUCCH simultaneously on a plurality of up CC, so, how UE distributes the transmitted power on up a plurality of CC to remain the problem that a needs solves.

(4) scheduling mechanism of a plurality of descending carriers

Just as mentioned before, the PCFICH probability of false detection when striding carrier dispatching in the LTE-A system in order to make be consistent with carrier dispatching, need research to reduce the method for the PCFICH probability of false detection when striding carrier dispatching.(application number: the embodiment 2 200910177191.8) has proposed a kind of control format indicating means of striding the cyclic redundancy check (CRC) based on PDCCH (the Cyclic Redundancy Check) mask under the carrier dispatching as Fig. 1 in the Chinese invention patent application.Concrete grammar is: in the CRC that strides the pairing Downlink Control Information DCI of PDCCH (Downlink ControlInformation) form that carrier dispatching uses, add with the carrier wave that carries PDSCH on the relevant mask (mask) of control format.Subscriber equipment just can be in blind Detecting PDCCH, by checking different CRC masks, impliedly obtains to carry the control format information on the carrier wave of PDSCH.Similar idea (Views on Solution to PCFICH DetectionError, R1-094237, RAN1 #58bis, NTT DOCOMO, October, 2009) also on the books in open source literature.

Adopt the problem of this method to be: owing to introduced the CRC mask, for each subscriber equipment, the number of times of CRC check can increase, and may bring the increase of PDCCH false alarm probability thus.

In view of the PHR method of the present existing in the world PUCCH at the LTE-A system not comprehensively and concrete, therefore, be necessary to seek PHR method, base station and the subscriber equipment of a kind of comprehensive, efficient and simple and practical PUCCH.And, the present invention is directed in the control format indicating means based on the CRC mask of PDCCH of striding in the LTE-A system under the carrier dispatching and exist false alarm probability to increase this problem, flexibly simple solution has been proposed.Therefore, the method, base station and the subscriber equipment that propose of the present invention can be used for the LTE-A system and following the 4th generation cell mobile communication systems or other communication systems.

Embodiment

To a preferred embodiment of the present invention will be described in detail, having omitted in the description process is unnecessary details and function for the present invention with reference to the accompanying drawings, obscures to prevent that the understanding of the present invention from causing.At length set forth performing step of the present invention for clear, provide some specific embodiments of the invention below, be applicable to LTE, LTE-A, 4G cellular communication system.Need to prove, the invention is not restricted to the application described in the embodiment, but applicable to other wireless communication systems.

Fig. 1 shows the schematic diagram according to the multicarrier lens system of LTE-A of the present invention.In the LTE-A system, the down link of base station BS-100 comprises 5 continuous or discrete unit carrier wave frequency ranges (CC, component carrier), promptly descending CC1, CC2, CC3, CC4, CC5, as shown in Figure 1.In whole wireless area, a plurality of user equipment (UE)s-100, UE-101, UE-102 can transmit on one or more up CC respectively, the set of up link CC comprises 5 continuous or discrete CC, promptly up CC1, CC2, CC3, CC4, CC5, as shown in Figure 1.BS-100 can adopt one or more downlink or uplink CC respectively according to the size of the data traffic of down link or up link at a plurality of subscriber equipmenies: as Fig. 1, in the communicating by letter of BS-100 and UE-100, down link adopts 5 CC (DL CC1, CC2, CC3, CC4, CC5), and up link adopts 3 CC (UL CC1, CC2, CC3); And for example in the communicating by letter of BS-100 and UE-101, down link adopts 3 CC (DL CC2, CC4, CC5), and up link adopts 3 CC (UL CC4, CC5); In the communicating by letter of BS-100 and UE-102, down link adopts 2 CC (DL CC1, CC2) for another example, and up link adopts 1 CC (UL CC1).Down link between BS-100 and a plurality of subscriber equipment or the transmission of the signaling of up link then are the problems of more complicated, the principle of signaling transmission is to have the try one's best few link overhead and the low implementation complexity of trying one's best under the prerequisite of the system of assurance operate as normal, therefore, up signaling or downlink signaling can transmit on one or more up CC or descending CC respectively, but must have simply and realization mechanism efficiently.

Fig. 2 shows the schematic diagram of the uplink power control of multicarrier lens system.In the LTERelease-8.0 system, uplink power control comprises the power control of PUSCH, the power control of PUCCH, the power control of SRS, as shown in Figure 2, represent that respectively UE is in the power division and the adjustment that send upstream data, upstream control signaling, SRS, shown in formula as mentioned in the above (1), (2), (3).

Fig. 3 shows the PUCCH of multicarrier lens system and the schematic diagram that PUSCH transmits simultaneously.In LTE Release-8.0 system, for fear of peak-to-average force ratio (PAPR, peak-to-averagepower ratio) improves and systematic function is descended, same UE can not send data and control signaling simultaneously, promptly same UE or only send data in any subframe perhaps only sends upstream control signaling.It is to be noted, same UE in a subframe only the two ends in transmission bandwidth send PUCCH, and only some is available not mean that frequency resource in this subframe, in fact, these frequency resources still can send the data of other UE, that is to say, in any subframe, can use all frequency resources to send data and control signaling simultaneously, only these data must come from different UE with the control signaling.PUCCH that LTE Release-8.0 finally determines and the distribution of PUSCH in subframe be as shown in Figure 3: in previous subframe, the height two ends of UE-300 and the UE-301 frequency in the subframe of 1ms take the time slot (slot) of a 0.5ms respectively, and UE-300 and UE-301 all do not transmit the data of PUSCH when the control signaling of same subframe transmission PUCCH; In a back subframe, UE-300 only transmits the data of PUSCH and does not transmit the control signaling of PUCCH, and UE-301 only transmits the control signaling of PUCCH and do not transmit the data of PUSCH.The LTE-A system has then relaxed the constraint to UE, same UE can transmit data and control signaling simultaneously respectively on PUSCH and PUCCH in same subframe, as the UE-302 among Fig. 3, at this moment, in same subframe, other subscriber equipmenies still can transmit the control signaling of PUCCH, as UE-303.Here, it should be noted that: under the unrestricted situation of UE transmitted power, UE can freely distribute total transmitted power on PUSCH and PUCCH, and the ability of use PUSCH and PUCCH was not subjected to the restriction of power when UE had; But when UE is in the wireless area edge, and the transmitted power of UE is not enough to support UE when carrying out the Uplink MIMO transmission of high order (Rank＞2) smoothly, the UE transmitted power is restricted, though UE has the ability of using PUSCH and PUCCH simultaneously, but UE can not freely distribute total transmitted power on PUSCH and PUCCH, therefore, UE must report the transmitted power that consumes respectively on PUSCH and/or PUCCH to BS, so that BS carries out scheduling of resource flexibly, adjust the modulation system of uplink, coded system, the transmitted power of PUSCH, the transmitted power of PUCCH, thus carrying out smoothly of PUSCH uplink power control process and PUCCH uplink power control process guaranteed.Here, UE is power headroom reporting (PHR, power headroomreporting) problem to the transmitted power of BS report consumption at PUSCH and/or PUCCH.

Fig. 4 show LTE Release-8.0 PHR mechanism schematic diagram.The Objective of Report of PH is that the difference of the maximum transmission power of UE nominal and Physical Uplink Control Channel (PUCCH, physicaluplink control channel) estimating power is offered BS, and the PH definition of UE as shown in Equation (4).The process of PH report may further comprise the steps as shown in Figure 4 in the LTE Release-8.0 system: when the trigger event of the PHR of PUSCH takes place, trigger the PHR process (step 1) of UE-400; When if UE-400 does not have upstream data to send, UE-400 does not send dispatch request (SR, scheduling request) signal and gives BS-400, if when UE-400 has data to send, send dispatch request (SR, scheduling request) signal and give BS-400 (step 2); After BS-400 receives the SR signal that UE-400 sends, carry out ascending resource scheduling (step 3), the needed schedule information of uplink of ascending resource scheduling decision UE, schedule information comprises size of position in sub-frame of uplink of the number of up RB and these RB, up MCS mode (comprising modulation system, coded system), uplink transmission block (TB, tranmission block) or the like; BS-400 by PDCCH send UL Grant signal to UE-400 (step 4), UL Grant comprises the needed schedule information of the uplink of UE-400; UE-400 calculates pH value (step 5), the i.e. difference of nominal maximum transmission power of UE and Physical Uplink Shared Channel estimating power of PUSCH; UE-400 sends data and pH value to BS-400 by PUSCH, and triggering or replacement PHR timer (step 6).

Fig. 5 shows the schematic diagram of the PHR mechanism based on SR of the present invention.Purpose of the present invention is different from the PHR mechanism of the PUSCH of LTE Release-8.0, the present invention is intended to seek the PHR mechanism of a kind of PUCCH, as shown in Figure 5, PHR process based on SR of the present invention may further comprise the steps: when the PHR of PUCCH trigger event takes place, trigger the PH reporting process (step 1) of UE-500; UE-500 sends SR to BS-500 (step 2), here SR is that UE-500 initiatively is sent to BS-500, upstream data need not transmit on PUSCH, and therefore, the SR signal forwarding step (step 2) among this step and the LTERelease-8.0 (Fig. 4) is essentially different; After BS-500 receives the SR signal that UE-500 sends, carry out ascending resource scheduling (step 3), the needed schedule information of uplink of ascending resource scheduling decision UE, schedule information comprises number and position, up MCS mode (comprise modulation system, coded system), the uplink transmission block (TB of these RB in sub-frame of uplink of up RB, tranmission block) size or the like, the resource of all uplink schedulings here all are used to transmit the upstream data of PHR information rather than LTE Release8.0; BS-500 by PDCCH send UL Grant signal to UE-500 (step 4), UL Grant comprises the needed schedule information of uplink PHR information of UE-500; UE-500 calculates pH value (step 5), the i.e. difference of nominal maximum transmission power of UE and Physical Uplink Control Channel estimating power of PUSCH; UE-500 sends data and pH value to BS-500 by PUSCH, and triggering or replacement PHR timer (step 6).

Fig. 6 shows the schematic diagram of the PHR mechanism based on the L1 signaling of the present invention.As shown in Figure 6, the PHR process based on the L1 signaling may further comprise the steps: when the trigger event of PUCCH takes place, trigger the PHR process (step 1) of UE-600; UE calculates the pH value (step 2) of PUCCH; UE-600 sends pH value to BS-600 by the L1 signaling of PUCCH, and triggering or replacement PHR timer (step 3).

Fig. 7 shows the schematic diagram of trigger mechanism of PHR of the PUSCH of LTE Release-8.0.

The trigger mechanism of the PHR of PUSCH is realized by three kinds of trigger mechanisms, as shown in Figure 7, comprise and forbid PHR timer (prohibitPHR-Timer), periodically PHR timer (periodicPHR-Timer), upper-layer configured (configure) or reconfigure (reconfigure).The upper strata is by configuration (configure) two timers, i.e. PHR timer (periodicPHR-Timer) and forbid PHR timer (prohibitPHR-Timer) periodically, control PHR, and RRC also can trigger timer by change (DL-PathlossChange) value that the downlink path loss is set.PHR can be by following Event triggered: prohibitPHR-Timer then or then, and the change of path loss surpasses DL-PathlossChange dB value, and when UE had ascending resource to carry out new transmission, UE carried out PHR; PeriodicPHR-Timer then.In addition, also can dispose or reconfigure and control PHR by upper strata (upper layer).

Fig. 8 shows the schematic diagram of trigger mechanism of the PHR of PUCCH of the present invention.Consider the PHR mechanism of the PUCCH that is based on initiative SR that the present invention proposes and based on the PHR mechanism of the PUCCH of L1, therefore, trigger mechanism for the PHR of the PUSCH that is different from LTE Release-8.0, the present invention can define the process that a kind of new timer (being PUCCH-PHR-Timer) is controlled PHR, as Fig. 8 (a) with (b).In Fig. 8 (a), (for example: 1. not to the BS report, promptly timer PUCCH-PHR-Timer then for a long time for the PHR of PUCCH when the PHR of PUCCH trigger event takes place; Perhaps 2. the DL path loss values of PUCCH changes greater than predetermined variance threshold; Perhaps 3. the downlink path loss value of subscriber equipment measurement changes greater than predetermined variance threshold; Perhaps 4. subscriber equipment is gone the transmitting power of control channel physically near maximum transmission power; Perhaps 5. subscriber equipment receives that the number of times of power control instruction of closed loop Physical Uplink Control Channel is greater than setting in advance number of times) time, the PUCCH-PH reporting process is triggered, UE initiatively sends the SR signal and gives BS, BS carries out ascending resource scheduling and passes through UL Grant the information notification UE after dispatching after receiving the SR signal, UE calculates the pH value of PUCCH and sends PH information by PUSCH to BS, triggers afterwards or replacement PHR timer PUCCH-PHR-Timer; In Fig. 8 (b), (for example: 1. not to the BS report, promptly timer PUCCH-PHR-Timer then for a long time for the PHR of PUCCH when the PHR of PUCCH trigger event takes place; Perhaps 2. the DL path loss values of PUCCH changes greater than predetermined variance threshold; Perhaps 3. the downlink path loss value of subscriber equipment measurement changes greater than predetermined variance threshold; Perhaps 4. subscriber equipment is gone the transmitting power of control channel physically near maximum transmission power; Perhaps 5. subscriber equipment receives that the number of times of power control instruction of closed loop Physical Uplink Control Channel is greater than setting in advance number of times) time, the PUCCH-PH reporting process is triggered, UE by the L1 signaling (for example calculates behind the pH value of PUCCH, the CQI signaling) sends PH information to BS, trigger afterwards or replacement PHR timer PUCCH-PHR-Timer, make PHR timer PUCCH-PHR-Timer effective.It is to be noted in the present invention: though the present invention has defined the generation that the PHR timer PUCCH-PHR-Timer of a kind of PUCCH represents the PHR trigger event, but the present invention do not get rid of with existing two timers of PHR (for example, prohibitPHR-Timer and periodicPHR-Timer) and/or the upper-layer configured (configure) of PUSCH in the LTE Release-8.0 system and/or reconfigure that (reconfigure) realize that the present invention proposes as indicated above based on SR with based on PHR method, base station and the subscriber equipment of the PUCCH of L1.

[first embodiment]

According to the first embodiment of the present invention, the method for the power headroom reporting (PHR) of a kind of PUCCH has been proposed, as shown in Figure 9, show schematic diagram according to the PHR method of the PUCCH of first embodiment of the invention.Whole wireless area comprises base station BS-700 and UE-700, carrier wave frequency range (the CC of unit of down link, component carrier) set comprises DL CC1, DL CC2, DL CC3, DL CC4, DL CC5 totally 5 unit carrier wave frequency ranges, and up link is got 1 UL CC, as UL CC1.The number of wherein concrete descending DL CC can be selected by the method for carrier dispatching mentioned above, and present embodiment will further describe out concrete implementation method.Flow chart according to the PHR method of the PUCCH of first embodiment of the invention as shown in figure 10, may further comprise the steps:

Step 1:UE-700 judges whether the PHR trigger event of PUCCH (for example takes place, whether the PHR timer lost efficacy, be timer whether then, perhaps whether the DL path loss values of PUCCH changes greater than predetermined variance threshold, or other trigger events mentioned above)? if the PHR trigger event takes place, then enter S101, if the PHR trigger event does not take place, then enter S104, shown in S100;

(for example, not to the BS-700 report, promptly the PHR timer then for a long time for the pH value of the PUCCH of UE-700) takes place in step 2:PHR trigger event, and then UE-700 triggers the PH reporting process, shown in S101;

The present invention is with the long-time a kind of trigger event that also is not defined as the PHR of PUCCH to the BS report of the pH value of PUCCH in the LTE-A system, and the triggering of the PH reporting process of PUCCH and the concrete setting of PUCCH-PHR-Timer can be with reference to figure 8 (a).

Step 3:UE-700 initiatively sends dispatch request (SR) signal to BS-700 after the PH of PUCCH reporting process is triggered, the SR signal sends to BS-700 by the PUCCH channel, shown in S102;

After step 4:BS-700 receives the SR signal, carry out ascending resource scheduling, the needed schedule information of uplink of ascending resource scheduling decision UE, schedule information comprises number and position, up MCS mode (comprise modulation system, coded system), the uplink transmission block (TB of these RB in sub-frame of uplink of up RB, tranmission block) size or the like is shown in S103;

Does step 5:BS-700 judge that PDSCH has the downstream data traffic request? if BS-700 has downlink data to need to send, enter S105; If BS-700 does not have downlink data to need to send, enter S106, shown in S104;

Step 6: if BS-700 has downlink data to need to send, BS-700 carries out carrier dispatching, shown in S105.

Just as mentioned before, because the LTE-A system is the multicarrier lens system and has 5 continuous or discrete descending CC, and BS carries out downlink data transmission by PDSCH and may not need simultaneously with full 5 descending CC, therefore, BS is necessary to carry out the scheduling of descending CC, and the purpose of descending CC scheduling is to satisfy the transmission of downlink data under the prerequisite that guarantees transmission quality with few CC that tries one's best.Figure 11 shows the schematic diagram based on the control format indicating means of the CRC mask of PDCCH of striding under carrier wave (CC) scheduling.

Based on this for stride under the carrier dispatching based on the improving one's methods of the control format indicating means of the CRC mask of PDCCH, the particular flow sheet of subscriber equipment as shown in figure 14:

1401: subscriber equipment detects the physical format indicating channel PCFICH on the carrier wave that carries PDCCH in the current subframe, obtains the control format on this carrier wave in this subframe;

1402: in the control information zone on this carrier wave of this subframe that is obtained, by Radio Network Temporary Identifier symbol RNTI and CRC mask 1, blind Detecting PDCCH;

If detect, turn to step 404, if do not detect, turn to step 403;

1403: in the control information zone on this carrier wave of this subframe that is obtained, by Radio Network Temporary Identifier symbol RNTI and CRC mask 2-4, blind Detecting PDCCH;

If detect, turn to step 405;

1404: the indicated carrier wave of carrier wave indication territory CIF (Carrier IndicatorField) that detects descending distribution PDCCH;

If this carrier wave, promptly carry the carrier wave of PDCCH, turn to step 407, otherwise turn to 406;

1405: determine the control format of the carrier wave of the carrying PDSCH that CIF is indicated to turn to step 407 according to the CRC mask;

1406: detect the PCFICH of the carrier wave of the indicated carrying PDSCH of CIF, obtain control format;

1407: subscriber equipment obtains the resource block assignments information of PDSCH from this PDCCH;

1408: subscriber equipment is according to the control format information on the carrier frequency of the resource block assignments information of the PDSCH that is obtained and the carrying PDSCH that obtained, and next OFDM sign-on in the control information zone from this carrier frequency of current subframe takes out PDSCH.

Step 7:BS-700 by PDCCH send UL Grant signal and/or descending distributing signal to UE to UE, UL Grant comprises the needed schedule information of the uplink of UE, descending distributing signal comprises that the control format of CRC mask indicates to UE shown in S106;

Here, if BS-700 does not carry out carrier dispatching, then BS-700 does not need to send by PDCCH to UE-700 the descending distributing signal of the control format indication information that comprises the CRC mask in this step; If BS-700 carries out carrier dispatching, then BS-700 need send the descending distributing signal of the control format indication information comprise the CRC mask to UE-700 by PDCCH, the data that BS-700 also need send to UE-700 by PDSCH on behind the selected carrier dispatching or descending CC.

Step 8:UE-700 receive on the PDCCH UL Grant signal and down/or descending distributing signal, UE-700 receives the data-signal on the PDSCH, then, UE-700 calculates the pH value of PUCCH shown in S107;

Wherein the pH value of PUCCH is the difference that nominal maximum transmission power of UE and PUCCH go up estimating power.Here, the present invention does not specify the pH value that whether calculates PUSCH, but the present invention does not limit the pH value that whether needs to report PUSCH on the PUSCH, if report, the pH value of PUSCH can adopt with LTE Release-8.0 and similarly define, and promptly nominal maximum transmission power of UE and PUSCH go up the difference of estimating power.Because up link and down link all can adopt many CC technology, therefore, the estimating power of the PUSCH that calculates respectively according to formula (1) and (2) and the estimating power of PUCCH all are based on each carrier wave (CC specific) in the LTE-A system.

Step 9:UE-700 triggers or replacement PHR timer PUCCH-PHR-Timer afterwards by the pH value of PUSCH report PUCCH, makes PHR timer PUCCH-PHR-Timer effective, shown in S108;

Here, the present invention it is to be noted: though the present invention has defined the generation that the PHR timer PUCCH-PHR-Timer of a kind of PUCCH represents the PHR trigger event, but the present invention do not get rid of with existing two timers of PHR (for example, prohibitPHR-Timer and periodicPHR-Timer) and/or the upper-layer configured (configure) of PUSCH in the LTE Release-8.0 system and/or reconfigure that (reconfigure) realize that the present invention proposes as indicated above based on SR with based on PHR method, base station and the subscriber equipment of the PUCCH of L1.

The PH method for reporting based on the PUCCH of SR that the present invention proposes is to allow UE-700 that pH value is used as upstream data. signals in essence, therefore, must use the pH value of PUSCH channel to BS-700 report PUCCH.Here, the present invention does not point out whether UE-700 needs the pH value of BS-700 report PUSCH, but must see: the PHR of PUSCH and the PHR of PUCCH are processes independently mutually, and the variation of the pH value of the pH value of PUSCH and PUCCH all is processes at a slow speed, therefore, BS-700 does not consider the influence of ascending resource scheduling when doing up PUSCH power control and the control of up PUCCH power, do not need to consider the influence of the PHR of PUSCH when therefore, UE-700 carries out the PHR of PUCCH.

Step 10:BS detects pH value, shown in S109;

Though the present invention considers the PHR process of PUCCH and the PHR process of PUSCH separately, but consider it is that PHR or the process of the PHR of PUSCH itself of PUCCH is not very frequent process, that is to say that the pH value of PUCCH and the pH value of PUSCH are the values that changes at a slow speed, therefore, the pH value of the pH value of PUCCH and PUSCH can adopt the mode of reports such as combined coding, Combined Treatment, difference processing to report to BS-700.In addition, because the introducing of a plurality of CC of up link, BS must detect the call number of a plurality of UL CC when detecting pH value.

Step 1:UE-800 judges whether the PHR trigger event of PUCCH (for example takes place, then whether the PHR timer, perhaps whether the DL path loss values of PUCCH changes greater than predetermined variance threshold, perhaps other trigger events)? if the PHR trigger event takes place, then enter step S201,, then still return this step if the PHR trigger event does not take place, cycle criterion is shown in S200;

(for example, not to the BS-800 report, promptly the PHR timer then for a long time for the pH value of the PUCCH of UE-800) takes place in step 2:PHR trigger event, and then UE-800 triggers the PH reporting process, shown in S201;

Step 3:UE-800 initiatively sends dispatch request (SR) signal to BS-800 after the PH reporting process is triggered, the SR signal sends to BS-800 by the PUCCH channel, shown in S202;
