In long term evolution (long term evolution, LTE) system, the transmission of upstream data is dispatched based on base station , the basic time unit of scheduling is subframe (subframe), and subframe includes multiple time-domain symbols.Specific scheduling flow are as follows: Base station sends down control channel, such as PDCCH or EPDCCH, the down control channel can be carried for dispatching physical uplink The scheduling information of shared channel (physical uplink shared channel, PUSCH), the scheduling information is for example including money The control information such as information, modulation coding scheme is distributed in source.Terminal device detects down control channel in subframe, and according to detection The scheduling information carried in down control channel out carries out the reception of downstream data channel or the transmission of uplink data channels.

The carrier widths that LTE system is supported at present are up to 20MHz, and subcarrier spacing is generally fixed for 15kHz.? In the frame structure of LTE system, there is the concept of resource block (resource block, RB).The bandwidth of one RB is 180kHz, by The subcarrier that 12 bandwidth are 15kHz forms, and occupies a time slot (slot), i.e. 0.5ms, so 1 RB reality in the time domain On be the carrier wave that 0.5ms, bandwidth 180kHz on frequency domain are occupied on time-frequency.If terminal device is detected in subframe n and is used for The PDCCH of PUSCH is dispatched, then the subframe that the PUSCH is sent is subframe n+k.Wherein, for frequency division duplex (frequency Division duplexing, FDD) for system, k=4.To time division duplex (time division duplexing, TDD) For system, different different with the value of subframe n according to the subframe of TDD proportion, the value of k is as shown in table 1:

In addition, supporting a variety of subcarrier spacings in NR system to adapt to different business demands.On frequency domain, NR system branch The calculation for the subcarrier spacing held is f_sc=f₀*2^m.Wherein, f₀=15kHz, m are integers.In the time domain, it provides as follows Some chronomeres, comprising:

The length of ■ subframe (subframe), 1 subframe is 1ms, in the structure of 15kHz subcarrier spacing It (numerology) include 14 orthogonal frequency division multiplexing (Orthogonal Frequency Division under Multiplexing, OFDM) symbol.In 1 subframe, to the various of the subcarrier spacing of 15kHz and 15kHz or more The character boundary of numerology is alignment.Wherein, unless otherwise specified, then " symbol " hereinafter each means that OFDM is accorded with Number.

■ time slot (slot) is a kind of time span of possible scheduling unit.1 slot includes currently used Y symbol under numerology.It include integer slot in 1 subframe.For example, subcarrier spacing be 60KHz with Under situation when, y=7；When subcarrier spacing is the situation of 60kHz or more, y=14.

The mini time slot of ■ (Mini-slot) is the minimum time length of scheduling unit.The OFDM that 1 Mini-slot includes Symbol can be less than y symbol under currently used numerology.

S42, terminal device send the first power headroom reporting (PHR) to the network equipment by the first Physical Uplink Shared Channel, then The network equipment receives the first power headroom reporting (PHR) by the first Physical Uplink Shared Channel.First time unit meets power headroom Reporting conditions.

In the embodiment of the present application, first time unit belongs to the second time quantum, and first time unit is the first kind Time quantum, the second time quantum are Second Type time quantums, and the length of first kind time quantum is the first length, second The length of type of time unit is the second length, and the second length is greater than the first length.Such as the length of first kind time quantum The length of less than one time slot (slot), if a slot is 0.5ms, the length of first kind time quantum is less than 0.5ms, the length of first kind time quantum is without being limited thereto in certain the embodiment of the present application, such as first kind time quantum Length is also less than a subframe, if a subframe is 1ms, the length of first kind time quantum is less than 1ms.? In communication system where terminal device and the network equipment, first kind time quantum and Second Type time quantum are used to adjust Spend PUSCH.That is, the scheduling granularity of at least two time domains can be used in the same communication system in the embodiment of the present application, Wherein first kind time quantum and Second Type time quantum all can serve as to dispatch granularity used in communication system.Example Such as, Second Type time quantum be TTI, then first kind time quantum can be sTTI, then the network equipment can by TTI come Dispatch terminal equipment sends PUSCH, or can also send PUSCH by sTTI come dispatch terminal equipment, wherein the network equipment It can be short PUSCH (short PUSCH, sPUSCH) by the PUSCH that sTTI dispatch terminal equipment is sent.Alternatively, the first kind Type time quantum is time slot (slot), then Second Type time quantum can be mini time slot (Mini-slot), then the network equipment PUSCH can be sent come dispatch terminal equipment by slot, or can also be by Mini-slot come the transmission of dispatch terminal equipment PUSCH.Certainly it as above only illustrates, reality of the embodiment of the present application for first kind time quantum and Second Type time quantum Existing form is with no restrictions.

Under the premise of uplink power control, terminal device can send power headroom reporting (PHR) (power in the specific time Headroom report, PHR), what PHR was indicated is the terminal except when except transimission power used in preceding PUSCH transmission Equipment also how many transimission power can be used, in this case, the maximum transmission power that PHR, that is, terminal device allows with work as The preceding difference assessed between obtained PUSCH transmission power, can be expressed simply as: PH=with formula UEAllowedMaxTransPower-PuschPower.Alternatively, PHR expression is PUSCH transmission and physics except when preceding Uplink control channel (Physical Uplink Control Channel, PUCCH) transmits except used transimission power, Terminal device also how many transimission power can be used, in this case, the maximum transmission power that PHR, that is, terminal device allows Difference between the PUSCH transmission power obtained with evaluation and PUCCH transimission power can be indicated simply with formula Are as follows: PH=UEAllowedMaxTransPower-PuschPower-PucchPower.During following discussion, with PHR For being the difference between the maximum transmission power that terminal device allows and the obtained PUSCH transmission power of evaluation.

Wherein, the unit of PH is dB.For example, the range of PH is [- 23dB ,+40dB].Since the calculating of PH needs to use To the transimission power of PUSCH, therefore terminal device can calculate PH in the transmission subframe of PUSCH.Why pH value, reason are defined One of be it can be used as the network equipment distribution uplink RB resource a reference frame.For example, being indicated if pH value is negative Current PUSCH transmission power alreadys exceed the maximum transmission power of terminal device permission, can be considered and subtracts in scheduling next time The RB resource allocation of few terminal device；And if pH value is positive, the RB number of subsequent allocations can also continue to increase.? If meeting the trigger condition of PHR in one subframe, and there is PUSCH scheduling in current subframe, then terminal device can be to The network equipment sends PHR.

In addition, supporting carrier wave to polymerize (Carrier Aggregation, CA) technology in system, i.e., the network equipment is multiple Carrier wave is allocated to a terminal device to promote the message transmission rate of terminal device.Carrier wave polymerization under CC according to carrying function Main plot (Primary Cell, PCell) and secondary cell (Secondary Cell, SCell) can be divided into.Main plot and secondary cell Concept it is as follows: Primary Cell (PCell): main plot is cell of the work in main band.Terminal device is in the cell Initial connection establishment process is carried out, or starts connection re-establishment process.The cell is indicated as main plot in handoff procedure； Secondary Cell (SCell): secondary cell is cell of the work on auxiliary frequency band.Once wireless heterogeneous networks (radio Resource control, RRC) it connects and establishes, secondary cell may be configurable to provide additional radio resource；Serving cell (Serving Cell): the terminal device of RRC connection (RRC_CONNECTED) state, if not configuring CA, only one are in A Serving Cell, i.e. PCell；If being configured with CA, Serving Cell set is made of PCell and SCell.For The preferably management configuration battery consumption of the terminal device of CA, can be used the activation/deactivation mechanism of SCell.Usual net Network equipment only dispatches terminal device on the SCell of activation and sends Uplink Shared Channel.In addition, main plot is always at activation State.

In a subframe, terminal device is separate configurations in the maximum transmission power that each cell allows.At one In subframe, as long as any one cell meets the condition of power headroom reporting (PHR), then terminal device sends PHR.Terminal device hair The PHR sent includes each autocorrelative power headroom value of the cell of all activated state.More than the relevant power of the cell of each activated state Magnitude is that the maximum transmission power that the terminal device configured in the cell allows and terminal device subframe in the cell are sent Uplink Shared Channel transmission power difference.For instance in activated state cell have it is N number of, then terminal device send PHR in Including each autocorrelative power headroom value in N number of activation cell.But when terminal device sends PHR, N number of activation cell In presumable cell there is no PUSCH to be sent to the network equipment, at this point, without PUSCH send the relevant PHR of cell be void Quasi- power headroom value, the relevant PHR of cell for having PUSCH to send are real power margin value.Virtual power margin value refers to The maximum transmission power that the terminal device configured in the cell allows subtracts the virtual PUSCH in the cell and sends power.Virtually PUSCH, which sends power, for example can be terminal device according to the transmission power method of determination of PUSCH, with terminal device at this The PUSCH that cell is configured to send preset quantity is the transmission power for assuming determining PUSCH.The optional virtual PUSCH hair Send do not include in power PUSCH the relevant power adjustment of modulation coding scheme.Real power margin value refers to the cell The maximum transmission power that the terminal device of upper configuration allows subtracts the PUSCH in the cell and sends power.With virtual power surplus Value is compared, and real power margin value can reflect the transmission power headroom that more actual terminal device sends up channel, is The network equipment provides the information for being more effectively used for the uplink of dispatch terminal equipment.

It should be noted that can there are multiple cells to work on carrier wave in wireless communication system with frequency simultaneously, certain Under special screne, it is also assumed that the carrier wave in wireless communication system is equal with the concept of cell.Such as in carrier aggregation scene Under, the carrier index that can carry secondary carrier simultaneously when for terminal equipment configuration secondary carrier and work are in the auxiliary small of the secondary carrier The cell ID (Cell Indentify, Cell ID) in area, in such a case, it is possible to think the concept etc. of carrier wave and cell Together, for example one cell of one carrier wave of terminal device access and access is equivalent.

In the embodiment of the present application, after terminal device obtains the first instruction information, begin to carry out a group data packet, the data packet It is corresponding to be sent in first time unit.It include the first power headroom reporting (PHR) in the data packet.It is wrapped in first power headroom reporting (PHR) Include the power headroom of all cells in activated state in first time unit that terminal device is known when starting group packet Value.As described above, the cell in first time unit in activated state does not dispatch PUSCH, which also will include this The corresponding power headroom value of cell, unlike, such corresponding power headroom value of cell is the virtual function that terminal device calculates Rate margin value.Such as Fig. 5 is referred to, the network equipment is sent in cell 1 in subframe n-3 dispatch terminal equipment in subframe n+1 PUSCH, then terminal device receives the first instruction information in subframe n-3.After reception first indicates information, terminal device may be Subframe n-3, subframe n-2, subframe n-1, subframe n or subframe n+1 start a group packet.And terminal device is when starting group packet, it is believed that The not scheduled PUSCH on subframe n+1 of cell 2, but terminal device still can be sent in cell 1 together in subframe n+1 The scheduled corresponding power headroom value of cell 1 and the corresponding power headroom value of cell 2, the difference is that cell 1 is corresponding The power calculation for the PUSCH that power headroom value, which is terminal device, to be sent according to reality in cell 1 obtains, that is, cell 1 is corresponding Power headroom value is real power margin value, and the corresponding power headroom value of cell 2 is terminal device according to virtual power surplus The calculation method of report obtains, i.e. the corresponding power headroom value of cell 2 is virtual power margin value.

It should be noted that in the PHR that terminal device is sent in addition to including the corresponding power headroom value in above-mentioned activation cell, It can also include the maximum transmission power of the respective permission of the activation cell of corresponding configuration of all or part of power headroom value.

When first time unit reaches, terminal device judges the report condition whether first time unit meets PHR, If meeting power headroom reporting (PHR) condition, terminal device can send PHR to the network equipment, and if being unsatisfactory for power headroom report Announcement condition, then terminal device does not send PHR to the network equipment.If terminal device is in other cells of first time unit There is physical uplink shared channel scheduling, then terminal device can send PHR by the first Physical Uplink Shared Channel, can also lead to The Physical Uplink Shared Channel crossed in other cells of first time unit sends PHR.

Wherein, power headroom reporting (PHR) condition comprises at least one of the following:

Terminal device receives the signaling for adding main secondary cell.

As long as being considered as meeting power headroom reporting (PHR) condition that is, meeting at least one condition as above.Power headroom report Announcement forbids timer to be represented by prohibitPHR-Timer, and path loss threshold is represented by dl-PathlossChange. Wherein, power headroom reporting (PHR) forbids timer to reach the first power headroom reporting (PHR) and forbids timing threshold, refer to terminal device into ProhibitPHR-Timer when judging that goes just reaches the first power headroom reporting (PHR) and forbids timing threshold, i.e., just overtime.And function Rate headroom reporting forbids timer to have reached the first power headroom reporting (PHR) and forbids timing threshold, refers to and is sentenced in terminal device ProhibitPHR-Timer has just had reached the first power headroom reporting (PHR) and forbids timing threshold before disconnected, i.e., in terminal device ProhibitPHR-Timer just has timed, out before being judged.

Cyclical power headroom reporting timer can be expressed as periodicPHR-Timer.

After terminal device receives configuration information or the reconfiguration information of power headroom reporting (PHR), it is determined that meet more than power Reporting conditions are measured, for terminal device in the case where meeting the condition if scheduled send PUSCH, terminal device sends PHR, and Timer prohibitPHR-Timer and Cyclical power headroom reporting timer is forbidden to reset above-mentioned power headroom reporting (PHR).

After terminal device receives the signaling for activating the secondary cell being configured, it is determined that meet power headroom reporting (PHR) item Part, for terminal device in the case where meeting the condition if scheduled send PUSCH, terminal device sends PHR, and by above-mentioned function Rate headroom reporting forbids timer prohibitPHR-Timer and Cyclical power headroom reporting timer to reset.

After terminal device receives the signaling for adding main secondary cell, it is determined that meet power headroom reporting (PHR) condition, For terminal device in the case where meeting the condition if scheduled send PUSCH, terminal device sends PHR, and by above-mentioned power Headroom reporting forbids timer prohibitPHR-Timer and Cyclical power headroom reporting timer to reset.

In the embodiment of the present application, since terminal device will judge whether first time unit meets power headroom reporting (PHR) item Part then also relates to power headroom reporting (PHR) and forbids timer, path loss threshold and Cyclical power headroom reporting timer. The power headroom reporting (PHR) used when for example, terminal device being judged whether first time unit meets power headroom reporting (PHR) is forbidden fixed When device, path loss threshold and Cyclical power headroom reporting timer be expressed as A-prohibitPHR-Time, A- Terminal device is judged the second time quantum of Second Type by dl-PathlossChange and A-periodicPHR-Timer The power headroom reporting (PHR) used when whether meeting power headroom reporting (PHR) forbids timer, path loss threshold and Cyclical power Headroom reporting timer is expressed as B-prohibitPHR-Time, B-dl-PathlossChange and B- periodicPHR-Timer.Wherein, A-prohibitPHR-Time, A-dl-PathlossChange, A-periodicPHR- Timer, B-prohibitPHR-Time, B-dl-PathlossChange and B-periodicPHR-Timer can be nets Network equipment configures.

As an example, the network equipment is only terminal equipment configuration set of parameter, such as the network equipment is to terminal device The first configuration information is sent, the first configuration information is just used to forbid timing threshold for the first power headroom reporting (PHR) of terminal equipment configuration Value, first path loss threshold value and period 1 power headroom reporting (PHR) timing threshold.That is A-periodicPHR-Timer's Cyclical power headroom reporting timing threshold and B-periodicPHR-Timer Cyclical power headroom reporting timing threshold phase Together, the power headroom reporting (PHR) of A-prohibitPHR-Timer is forbidden more than the power of timing threshold and B-prohibitPHR-Timer Amount report forbids timing threshold identical, and A-dl-PathlossChange is identical with B-dl-PathlossChange, and these three The chronomere of parameter is all the second length.Thus, it can be understood that the first configuration information is for determining first kind time list Whether member and Second Type time quantum meet power headroom reporting (PHR) condition.Wherein, the period function of A-periodicPHR-Timer Rate headroom reporting timing threshold is foregoing period 1 power headroom reporting (PHR) timing threshold, hereafter also by B- The Cyclical power headroom reporting timing threshold of periodicPHR-Timer is known as period 1 power headroom reporting (PHR) timing threshold； It is that foregoing first power headroom reporting (PHR) is prohibited that the power headroom reporting (PHR) of A-prohibitPHR-Timer, which forbids timing threshold, The power headroom reporting (PHR) of B-prohibitPHR-Timer is hereafter also forbidden timing threshold to be known as the second power by only timing threshold Headroom reporting forbids timing threshold；A-dl-PathlossChange is foregoing first path loss threshold value, hereafter B-dl-PathlossChange is known as the second path loss threshold.

As another example, the network equipment is respectively the PHR and the second physical uplink of the first Physical Uplink Shared Channel The PHR of shared channel configures respective parameter, such as the network equipment sends the first configuration information and the second configuration to terminal device Information, then terminal device receives the first configuration information and the second configuration information that the network equipment is sent, and the first configuration information is used for Indicate that the first power headroom reporting (PHR) forbids timing threshold, first path loss threshold value and period 1 power headroom reporting (PHR) fixed When threshold value, the second configuration information be used to indicate the second power headroom reporting (PHR) forbid timing threshold, the second path loss threshold and Second round power headroom reporting (PHR) timing threshold, the first configuration information is for determining whether Second Type time quantum meets power Headroom reporting condition, second configuration information is for determining whether first kind time quantum meets power headroom reporting (PHR) item Part.In this case, the Cyclical power headroom reporting timing threshold and B-periodicPHR- of A-periodicPHR-Timer The Cyclical power headroom reporting timing threshold of Timer, the power headroom reporting (PHR) of A-prohibitPHR-Timer forbid timing threshold Forbid timing threshold and A-dl-PathlossChange and B- with the power headroom reporting (PHR) of B-prohibitPHR-Timer This three couples of dl-PathlossChange, the result of possible configuration is all identical, it is also possible to which configuration result is that at least one pair of them are not It is identical.Wherein, the unit of A-periodicPHR-Timer, A-prohibitPHR-Timer and A-dl-PathlossChange It is the second length, the list of B-periodicPHR-Timer, B-prohibitPHR-Timer and B-dl-PathlossChange Position is the first length.

That is, different parameters can also be respectively configured in the network equipment, it is also convenient for terminal device in this way according to different parameters Judged, can more meet the actual conditions of corresponding Physical Uplink Shared Channel.

According to such as preceding introduction it is found that in the TTI for meeting PHR trigger condition, there may be multiple sTTI scheduled SPUSCH, below just introduce, terminal device, which can choose, sends PHR in scheduled each sTTI, or also can choose Only a sTTI in scheduled sTTI sends PHR.And if only a sTTI in scheduled sTTI is sent out PHR is sent, then terminal device can choose arbitrary one scheduled sTTI and send PHR, or can also be according to pre-defined rule To select a scheduled sTTI to send PHR.Mainly introduce why terminal device selects one according to pre-defined rule below Scheduled sTTI sends PHR, and specifically how to select.

Fig. 6 is referred to, meets the trigger condition of PHR in TTI#n, but sTTI#8, sTTI#9 and sTTI#10 therein All be scheduled sPUSCH.A kind of pre-defined rule are as follows: first sTTI that terminal device has sPUSCH to send in the TTI is sent PHR, that is to say, that first time unit is that terminal device sends the first of Physical Uplink Shared Channel in the second time quantum A first kind time quantum.This is because the different sTTI in the TTI, the PHR that terminal device is sent is for the network equipment The transformation of the reference significance of scheduling is little, and terminal device reports a PHR can in the TTI.And terminal device exists When sTTI#2 receives the instruction information of the scheduling sPUSCH to sTTI#, subsequent sTTI#3, sTTI#4 etc. can or can not be received The instruction information of sTTI in TTI#n be it is uncertain, for the sake of assurance, terminal device receives pair in sTTI#2 It need to include PHR when preparing the data of the sPUSCH on sTTI#8 after the instruction of the scheduling sPUSCH of sTTI#8.

Therefore, above-mentioned PHR trigger condition judges it is using TTI as granularity.In the TTI for meeting PHR trigger condition, eventually First sTTI that end equipment should be scheduled in the TTI sends PHR.

Another problem is, if the sTTI that terminal device is scheduled in the TTI for meeting PHR trigger condition have it is multiple, But the network equipment and terminal device are scheduled in sTTI for these, which is that first sTTI may have different understanding.Example Such as, the scheduling information of actual first sTTI in scheduled sTII may be lost or not detected to terminal device, that is, eventually " first sTTI " that " first sTTI " and the network equipment that end equipment is understood are understood is not necessarily the same sTTI.Cause This, for the network equipment, blind Detecting PHR in the multiple sTTI that can be scheduled in the TTI, to prevent from omitting PHR. After the network equipment detects PHR in a wherein sTTI, the detection to the subsequent sTTI in the TTI can be stopped.

For example, scheduled 3 sTTI transmission sPUSCH in TTI#n altogether continuing with referring to Fig. 6, being in sTTI#2 tune respectively The sTTI#8 of degree, the sTTI#9 in sTTI#3 scheduling and the sTTI#10 in sTTI#4 scheduling.Then actually in the TTI One scheduled sTTI should be sTTI#8.The scheduling information in sTTI#2 is not detected in terminal device, then terminal device is not Know that sTTI#8 is first scheduled sTTI in the TTI, and terminal device detects the scheduling information in sTTI#3, because This terminal device will be considered that sTTI#9 is first scheduled sTTI in the TTI, then terminal device can be sent in sTTI#9 PHR.It for the network equipment, can be detected since sTTI#8, if PHR is not detected in sTTI#8, network is set Standby to will continue to detection sTTI#9, if the network equipment detects PHR in sTTI#9, the network equipment can stop detecting, nothing STTI#10 need to be detected again.In this way, can prevent the network equipment from omitting PHR, and the network equipment can stop after detecting PHR Detection, can also save the power consumption of the network equipment as far as possible.

Assuming that a scene: referring to Fig. 7, the network equipment sends uplink in subframe n+1 in subframe n-3 dispatch terminal equipment Data, and in the granularity of sTTI, 2nd sTTI dispatch terminal equipment of the network equipment in subframe n in subframe n+1 2 sTTI send upstream data.Since terminal device just has begun calculating after receiving the corresponding scheduling information of subframe n+1 The PHR of PUSCH in subframe n+1, that is, start a group data packet, and terminal device be not aware that at this time it is corresponding in the scheduling information There are also the scheduled transmission upstream data of sTTI in subframe n, the PHR for causing terminal device to send in subframe n+1 cannot include reporting Power headroom value corresponding to the channel of all transmission upstream datas at the time of PHR.And by provided by the embodiments of the present application Technical solution, the length of first time unit is less than the length of the second time quantum, and terminal device is in first time unit The first power headroom reporting (PHR) can be sent to the network equipment, thus when terminal device can send PHR transmission to the network equipment as far as possible The power headroom value of more accurate each cell is carved, is provided more effectively for the network equipment for the uplink of dispatch terminal equipment Information.

In addition, in the embodiment of the present application, terminal device can also obtain second indication information, second indication information is used for Instruction terminal equipment sends the second Physical Uplink Shared Channel in the second time quantum.Wherein, terminal device obtains the first instruction The time that the time of information and terminal device obtain second indication information is different.For example, terminal device is obtained in third time quantum The first instruction information is taken, obtains second indication information in the 4th time quantum, the initial time of third time quantum is earlier than the 4th The initial time of time quantum or the initial time of third time quantum are later than the initial time of the 4th time quantum.

For example, the network equipment can send second indication information to terminal device, then terminal device receives network equipment hair The second indication information sent.Such as second indication information is realized by DCI, is sent out for dispatch terminal equipment in the second time quantum Send the 2nd PUSCH.

Then terminal device sends the second power headroom reporting (PHR) to the network equipment by the second Physical Uplink Shared Channel, then net Network equipment receives the second power headroom reporting (PHR) by the second Physical Uplink Shared Channel.Second time quantum meets power headroom report Announcement condition.Here power headroom reporting (PHR) condition is identical as power headroom reporting (PHR) condition above-mentioned.Certainly, power headroom reporting (PHR) item Part includes a variety of, as long as meeting at least one therein, terminal device can send power headroom reporting (PHR) to the network equipment, that , terminal device sends the power headroom reporting (PHR) condition met when the first power headroom reporting (PHR) and terminal device sends the second function The power headroom reporting (PHR) condition met when rate headroom reporting can be same type of condition, such as all be to meet period function Rate headroom reporting timer reaches the condition of corresponding Cyclical power headroom reporting timing threshold or the two is also possible to difference The condition of type, such as it is period function that terminal device, which sends the power headroom reporting (PHR) condition met when the first power headroom reporting (PHR), Rate headroom reporting timer reaches the condition of period 1 power headroom reporting (PHR) timing threshold, and terminal device sends the second power The power headroom reporting (PHR) condition met when headroom reporting is that terminal device receives letter for activating the secondary cell being configured The condition of order.

It is sTTI, Second Type time quantum with first kind time quantum is that TTI, the first Physical Uplink Shared Channel are For sPUSCH, the second Physical Uplink Shared Channel are PUSCH, in the TTI for meeting PHR trigger condition, if terminal device Not only it had been scheduled and has sent PUSCH, but also in the scheduled transmission sPUSCH of at least one sTTI, be described below why terminal device will select The PHR of the PHR of sPUSCH and PUSCH is sent to the network equipment.

As shown in figure 8, meeting the trigger condition of PHR in TTI#n, wherein existing PUSCH is dispatched, also there is sPUSCH scheduling. If terminal device only sends PHR in PUSCH, since terminal device is believed in the second instruction that TTI#n-4 receives scheduling PUSCH Start the PUSCH group packet sent to TTI#n after breath, PHR is carried in PUSCH, and still, terminal device sets network at this time It is standby whether to dispatch that the sTTI in TTI#n sends sPUSCH and ignorant (possible network is set in next sTTI#2, sTTI#3 It is standby also the same to this it is not anticipated that).In this way, terminal device determines the PUSCH data in the PUSCH group packet sent to TTI#n PHR in packet.Wherein, for the up channel really sent in TTI#n, terminal device is small where determining the up channel When the power headroom value in area, which corresponds to the true transmission power of up channel, i.e., where the up channel The power headroom value of cell is real power margin value.For the cell for not having up channel to find in TTI#n, corresponding function Rate margin value is virtual power margin value.Under the scene for supporting CA, if terminal device is in the PUSCH group packet sent to TTI#n When, the PHR for including in the PUSCH is only capable of including that the terminal device that determines when group packet moment starts of terminal device is sent out in TTI#n Real power margin value corresponding to cell where the up channel sent, include for other cells, in PHR is only virtual function Rate margin value.As shown in figure 8, sTTI#2 of the terminal device in TTI#n-1 receives the network equipment to the sTTI#8 in TTI#n Instruction information for dispatching sPUSCH and sTTI#3 is received and is used for the sTTI#9 in TTI#n in TTI#n-1 Dispatch the instruction information of sPUSCH.In view of there is no embody sTTI#8 in the PHR that the PUSCH of TTI#n is sent for terminal device Or the sPUSCH of sTTI#9 is for the demand of power, so terminal device it is necessary in the sPUSCH sent in TTI#n again Another PHR, as PHR2 are sent, includes that cell where the sPUSCH sent in TTI#n is corresponding true in the PHR 2 Power headroom value includes the power headroom value determined by the true transmission power of sPUSCH in the real power margin value.Network Equipment is by receiving PHR2, available interior power headroom value corresponding with the up channel that the sPUSCH moment sends, to adjust The whole subsequent uplink data scheduling result to terminal device.

Therefore, in the TTI for meeting PHR trigger condition, if terminal device, which is not only scheduled, sends PUSCH, but also at least One sTTI is scheduled to send sPUSCH, sends to the network equipment then terminal device can choose in PUSCH and sPUSCH PHR, that is, report PHR1 in PUSCH, report PHR2 in sPUSCH.It, can be to be received in the TTI for the network equipment The later corresponding upstream data of instruction information of transmission in PHR subject to.For example, for the same scheduled TTI, Instruction information transmission for dispatching PUSCH is more early, and the instruction information transmission for being used to dispatch sPUSCH is later, then the network equipment After receiving PHR1 and PHR2, it can be subject to PHR2, PHR2 is exactly to send in the later corresponding upstream data of instruction information PHR。

That is, technical solution provided by the embodiments of the present application, allows the scheduling unit in longer Physical Uplink Shared Channel The PHR of the middle time quantum by different length is sent to the network equipment, and efficiently solving allows different length on a carrier wave Uplink channel transmission when PHR report problem.

Terminal device obtains the first instruction information, which is used to indicate the terminal device at the first time Unit sends the first Physical Uplink Shared Channel, and first time unit meets the condition that terminal device sends power headroom reporting (PHR)； Terminal device also obtains second indication information, and second indication information, which is used to indicate, sends the second physics in second time quantum Uplink Shared Channel, the second time quantum meet the condition that terminal device sends power headroom reporting (PHR).So, terminal device both leads to It crosses the first Physical Uplink Shared Channel and sends the first power headroom reporting (PHR) to the network equipment, also pass through the shared letter of the second physical uplink Road sends the second power headroom reporting (PHR) to the network equipment.The time of the first instruction information is obtained in terminal device and obtains the In the case that the time of two instruction information is different, terminal device can be effectively solved according to the function that scheduling instruction information determines earlier Rate headroom reporting not can accurately reflect the problem of practical up channel that sends of terminal corresponding power headroom reporting (PHR) value.

It is described as Fig. 8 illustrates, terminal device receives the second instruction letter that scheduling TTI#n sends PUSCH in TTI#n-4 Breath, the acquisition moment based on the second indication information, the up channel that the TTI#n that terminal device determines is sent are the second uplink letter The channel that road set includes, as shown in figure 9, by taking the carrier wave of the activation of terminal device is 3 carrier waves as an example, respectively carrier wave 1, carry Wave 2 and carrier wave 3.Terminal device gets the network equipment in subframe n-4 and dispatches it on subframe n, and carrier wave 1 and carrier wave 2 are sent out respectively Up channel 1 and up channel 2 are sent, then the second up channel set just includes up channel 1 and carrier wave 2 on carrier wave 1 On up channel 2, terminal device start according to second indication information group data packet when, it is known that the network equipment scheduled carrier wave 1 sends up channel 1 in TTI#n, and knows that the network equipment scheduled carrier wave 2 and send up channel 2 in TTI#n, but do not know The road network equipment also scheduled sTTI#8 and sTTI#9 of the carrier wave 3 in TTI#n and send up channel 3 and up channel 4, therefore Second up channel set does not include up channel 3 and up channel 4 on carrier wave 2.Certainly, terminal device can be counted for carrier wave 3 Calculate virtual power margin value, that is, terminal device includes carrier wave 1 in the PHR that the up channel 1 or up channel 2 of TTI#n are sent With the real power margin value of carrier wave 2 and the virtual power margin value of carrier wave 3.

Later, sTTI#2 of the terminal device in TTI#n-1 receives the network equipment to sTTI#8 for dispatching The first instruction information of sPUSCH, the acquisition moment based on the second indication information, what the sTTI#8 that terminal device determines was sent Up channel is the channel that the first up channel set includes.With continued reference to Fig. 9, since terminal device is starting to refer to according to first When showing information group data packet, it is known that the network equipment also scheduled carrier wave 3 and send 3 He of up channel in the sTTI#8 of TTI#n Carrier wave 3 sends up channel 4 in the sTTI#9 of TTI#n, therefore the first up channel set may include the uplink letter on carrier wave 3 Drink up channel 4 in road 3.That is, the first up channel set just includes the up channel 1 on carrier wave 1, the up channel on carrier wave 2 2 and up channel 3 and up channel 4 on carrier wave 3.At this point, terminal device be carrier wave 3 calculate be up channel 3 and it is upper The real power margin value of row channel 4.Here, it refers in the second up channel set that sTTI#8 is sent the sTTI#8's All up channels sent in time range.
