In addition, two kinds of waveforms in the application refer to original uplink waveform (referred to as " uplink waveform A " or " waveform in LTE A ") and NR in the new uplink waveform (referred to as " uplink waveform B " or " waveform B ") that introduces, uplink waveform can abbreviation wave Shape.

In order to facilitate understanding with power headroom reporting (PHR) (power headroom provided in an embodiment of the present invention is described Report, PHR) report method and waveform indicating means, the PHR in the embodiment of the present invention is introduced first below and its is answered Use scene.

The physical meaning of PHR is the maximum difference for sending the practical calculated uplink transmission power of power and UE of UE.? In LTE, carrys out assistant base station using PHR and carry out ascending resource distribution.

As shown in Figure 1, if there is ascending resource, UE will generate PHR, using the ascending resource to base after UE triggering PHR It stands and sends PHR and data.

If the calculated uplink transmission power of UE oneself sends power less than the maximum of UE, the value of PHR is positive number, UE It is sent according to oneself currently used power spectral density；If maximum hair of the calculated uplink transmission power of UE oneself greater than UE Power is sent, then the value of PHR is negative, and on the basis of oneself currently used power spectral density, power retracts UE, makes final The power of transmission sends power less than or equal to the maximum of UE.

In Fig. 1, the concrete trigger condition that UE triggers PHR can be any one or more of the following conditions:

1), periodic triggers；

2), the path loss variation of at least one activation serving cell is more than pre-determined threshold；

3), base station reconfigures PHR parameter；

4), secondary cell (secondary cell, SCell) activates, and the SCell has uplink.

It should be understood that the trigger condition enumerated above is merely illustrative and non-limiting.

In the embodiment of the present invention, the basic format for the PHR that UE is generated can be as shown in Figure 2.PHR shown in Fig. 2 includes UE All serving cells (cell of uplink activation) power headroom (power headroom, PH) value, pH value can also abbreviation PH, The PH of one cell refers to the cell in the power headroom for the current TTI for sending PHR.

C1 to c7 in Fig. 2 is that serving cell indexes (cell Index), and P is used to indicate whether to carry out back-off, and V is used It is true or virtual, R expression reserved bit in indicating pH value.Second row to fourth line indicates main plot (primary Cell, PCell) PH report；Fifth line to last line indicates that the PH of secondary cell is reported.Second row and the third line indicate master The type 2PH of cell and reporting for maximum carrier wave transmission power Pcmax, wherein type 2 refers to that UE is configured with simultaneous transmission The PH calculated in the case where PUSCH and PUCCH.Fourth line and fifth line indicate the type 1PH and maximum carrier wave of main plot Transmission power Pcmax's reports, it should be appreciated that the type 1PH of a cell refers to the cell in the number of PUSCH or PUCCH According to the power headroom of sending instant.Fifth line to last line indicates the type 1PH and maximum carrier wave transmission power of secondary cell Pcmax's reports.

When using PHR format shown in Fig. 2, as long as triggering a PHR, UE reports the PH that can report all cells every time Value, the size of this PHR is bigger, but this PHR can comprehensively report the Power related information of each cell of UE, in order to Base station carries out ascending resource distribution according to comprehensive PHR information.

In the format of another PHR of the embodiment of the present invention, the pH value of the cell portion of UE, the part can be only reported Cell can be UE and think current important, it should report the cell of pH value.The cell for not reporting PH for residue, then recognize For these cells it is current power spectral density variation less, if not reporting PH, do not influence to the UE these cells scheduling.

Therefore, in the embodiment of the present invention, can a cell portion report PH, can only include the cell portion of UE in PHR PH value and Pcmax value or PHR in only comprising UE cell portion pH value, do not include Pcmax value.Wherein, cell portion can Be UE cell in following any one or more of cell:

Intelligible, the cell of the UE in 1 to 7 refers to that all serving cells of UE, i.e. UE have up-link carrier below, and Cell in activated state.The serving cell of UE is specifically to provide the cell of service to UE, can be the cell under a base station The cell under service or multiple base stations, which is provided, to UE provides service to UE respectively.

1, the cell of uplink waveform has been converted in the cell of UE；

The uplink waveform that cell transformation uplink waveform can be the cell transforms to waveform B from waveform A, is also possible to from wave Shape B transforms to waveform A.The cell that uplink waveform has been converted in the cell of UE can also have multiple with only one.It is appreciated that , at the time of transformation uplink waveform herein at the time of, can refer to that UE generates the PHR, may also mean that UE generate PHR when In the time of several TTI before quarter.

Such as: when UE generates the PHR, in the cell of UE, only cell A has converted uplink waveform, then the PHR that UE is reported In contain only the pH value and Pcmax value of cell A, or contain only the pH value of cell A.

In such cases, the pH value for having modified the cell of uplink waveform is contained only in the PHR that UE is reported.

2, all cells in the bandwidth (band) where the cell of uplink waveform have been converted in the cell of UE；

Different from the 1st kind of situation, in such mode, not only comprising having converted uplink waveform in the 1st kind of situation Cell, further comprise other all cells in the bandwidth where the cell.

Such as: when UE generates the PHR, in the cell of UE, cell A has converted uplink waveform, and cell A is located at 400MHz's Bandwidth, there are also cell B and cell C under the bandwidth, then UE not only can reporting subdistrict A pH value, can also report with it with one The pH value of cell B and cell C under a bandwidth.In such cases, the cell under same bandwidth is contained only in the PHR that UE is reported A, the pH value and Pcmax value of cell B and cell C, or contain only the pH value of cell A under same bandwidth, cell B and cell C.

Equally, converted in the cell of UE uplink waveform cell can with only one, can also have it is multiple, if having more A, then UE can report the pH value of all cells in corresponding multiple bandwidth.

3, all cells in the cell group (cell group) where the cell of uplink waveform have been converted in the cell of UE；

It is same small that cell group in the embodiment of the present invention refers to that base station pre-configured some or multiple cells belong to District's groups, and configure a cell group ID.Such as base station can configure the one or more cells belonged in the same bandwidth Belong to the same cell group, in another example base station, which can configure the cell belonged in some path loss section, belongs to the same cell Group.

Different from the 1st kind, in such mode, not only comprising having converted the small of uplink waveform in the 1st kind of situation Area further comprises other all cells in the cell group where the cell.

Such as: when UE generates the PHR, in the cell of UE, cell A has converted uplink waveform, and cell A is located at cell group 1 In, there are also cell D and cell E in cell group 1, then UE not only can reporting subdistrict A pH value, can also report with it at one The pH value of cell D and cell E under cell group.In such cases, it is contained only in the PHR that UE is reported small under same cell group Area A, the pH value of cell D and cell E and Pcmax value, or contain only cell A, cell B under same cell group and cell C PH value.

Equally, converted in the cell of UE uplink waveform cell can with only one, can also have it is multiple, it is multiple when having When, if this multiple cell belongs to multiple cell groups, UE can report the PH of all cells in corresponding multiple cell groups Value；If this multiple cell belongs to the same cell group, UE can report the pH value of all cells in a corresponding cell group.

4, in the cell of UE signal strength be more than the first signal preset threshold cell；

The scheduling strategy of base station configuration, can be that the strong cell of preferential selection signal comes therefore can be preferential with UE communication Report the stronger cell of signal strength in the cell of UE.For example, signal strength is more than the cell of the first signal preset threshold.

A first signal preset threshold can be pre-configured to UE by base station only report the cell of UE when reporting pH value Middle signal strength is more than the pH value of the cell of the first signal preset threshold, other signal strengths are not above the first signal and preset threshold The cell of value, then do not report pH value.

In such cases, the cell PH that signal strength is more than the first signal preset threshold is contained only in the PHR that UE is reported Value and Pcmax value, or only include the cell pH value that signal strength is more than the first signal preset threshold.

Intelligible, signal strength can use Reference Signal Received Power (reference signal receiving Power, RSRP) or the signals such as Reference Signal Received Quality (reference signal receiving quality, RSRQ) Mass parameter indicates.

5, cell of the signal strength lower than second signal preset threshold in the cell of UE；

Base station can consider: smaller by being limited when distributing ascending resource to the stronger cell of signal strength；It is right It is bigger by being limited when distributing ascending resource in the weaker cell of signal strength, such as to the total bandwidth of ascending resource It is restricted.So base station can indicate the PH for the cell that UE preferentially reports signal strength weak according to strategy with configuration strategy, base station.

Similarly, a second signal preset threshold can be pre-configured to UE by base station only report UE's when reporting pH value For signal strength lower than the pH value of the cell of second signal preset threshold, other signal strengths are more than that second signal presets threshold in cell The cell of value, then do not report pH value.

In such cases, cell of the signal strength lower than second signal preset threshold is contained only in the PHR that UE is reported PH value and Pcmax value, or the only pH value comprising signal strength more than the cell of second signal preset threshold.

In addition, the 4th kind of front mode include report signal strength be higher than the first signal preset threshold cell PH, the 5 kinds of modes contain the PH for the cell for reporting signal strength lower than second signal preset threshold.Those skilled in the art should manage Solution, above two way combine, and also belong to protection scope of the present invention.That is: signal strength in the cell of UE is reported to be higher than first The PH of signal preset threshold and the PH for reporting the cell lower than second signal preset threshold.

6, signal strength strongest one or N number of cell in the cell of UE；

This case where reporting PH, is similar with the 4th kind, is all the cell for reporting signal strength strong.In this way, may be used The PH of signal strongest one or N number of cell in cell only to report UE.Specifically, RSRP value highest one can be reported only The PH of a or N number of cell；The PH of RSRQ value highest one or N number of cell can also only be reported, it will be appreciated that, signal strength is most Strong N number of cell refers to the preceding N number of cell of signal strength in the cell of UE.

In such cases, contained only in the PHR that UE is reported signal strength strongest one or N number of cell pH value and Pcmax value, or, containing only the pH value of signal strength strongest one or N number of cell.

7, one or the N number of cell that signal strength is most weak in the cell of UE；

This case where reporting PH, is similar with the 5th kind, is all the cell for reporting signal strength weak.In this way, may be used The PH of signal is most weak in cell only to report UE one or N number of cell.Specifically, RSRP value or RSRQ value can be reported only The PH of minimum one or N number of cell.Intelligible, the most weak N number of cell of signal strength refers to signal strength in the cell of UE By weak sequence is arrived by force, rearmost N number of cell is come.

In such cases, contained only in the PHR that UE is reported signal strength most weak one or N number of cell pH value and Pcmax value, or, containing only the pH value of signal strength most weak one or N number of cell.

It should be understood that 7 kinds enumerated above only report the mode of the pH value of cell portion merely illustrative and non-limiting.

In the embodiment of the present invention, UE can only report the pH value of the current important cell portion UE, remaining cell PH value wouldn't report, and therefore, can reduce the size of PHR under the premise of not influencing the scheduling to UE, to save wireless money Source.

In the above-described embodiment, the calculating of pH value and report be using cell as granularity (per cell) carry out, one In a little embodiments, the calculating of pH value and to report to be that granularity be carried out with wave beam (beam).Such as: when introducing high frequency cell Afterwards, each high frequency cell includes that several wave beams can calculate the PH of wave beam when calculating PH.

The wave beam can be understood as space resources, can refer to and prelist with sending or receiving for energy transmission directive property Code vector, and can go to identify this by index information and send or receive precoding vector.One UE can be in synchronization Using one or more in multiple and different precoding vectors, i.e., a wave beam or multiple wave beams can be formed simultaneously.

In a kind of implementation, as shown in figure 3, all serving cells in the PHR that UE is generated including UE (uplink activation Cell) each beam power headroom pH value, the PH of a wave beam refers to the wave beam of the cell in PUSCH or PUCCH Data sending instant power headroom.The meaning of the c1 to c7, P, V, type1 and type2 in PHR format in Fig. 3 can be with With reference to being described in Fig. 2.In Fig. 3, there are two wave beam (beam1 and beam2), each cells to have reported two wave beams for each cell PH value, each wave beam have oneself independent pH value.It is with one Pcmax value of each cell for Pcmax, shown in Fig. 3 For, in fact, being also possible to each wave beam reports a Pcmax.

When using PHR format shown in Fig. 3, if triggering a PHR, UE reports all beam of all cells every time PH value, the size of this PHR is bigger, but this PHR can comprehensively report the power phase of each beam in each cell of UE Information is closed, in order to which base station carries out ascending resource distribution according to comprehensive PHR information.

In another PHR format of the embodiment of the present invention, the pH value of the part wave beam in the cell of UE can be only reported. It should be understood that the part wave beam in the cell of UE may is that the part wave beam of each cell of UE, it is also possible to the cell portion of UE Part wave beam.

At this point, UE, which can be reported, thinks current important, it should report the wave beam of the cell of pH value.Not for residue Report the wave beam of the cell of PH, then it is assumed that these wave beams do not report currently, nor affect on the scheduling to the UE.

Therefore, in the embodiment of the present invention, in PHR can the only part wave beam comprising UE pH value and Pcmax value, can also be with The only pH value of the part wave beam of the cell comprising UE.Wherein, the part wave beam in the cell of UE can be it is following any or It is a variety of:

1, the wave beam of uplink waveform has been converted in the cell of UE；

Wherein, the cell of UE refers to all serving cells (cell of uplink activation) of UE.In wave beam transformation in cell The uplink waveform that traveling wave shape can be the wave beam transforms to waveform B from waveform A, is also possible to transform to waveform A from waveform B.UE Cell in converted uplink waveform wave beam can also have multiple with only one.

In such cases, the pH value for having modified the wave beam of uplink waveform and Pcmax value are contained only in the PHR that UE is reported, Or contain only the pH value for having modified the wave beam of uplink waveform.

For example, sharing 5 wave beams in cell 1, wherein there is 3 wave beams to change uplink waveform, in addition 2 do not change Uplink waveform shares 5 wave beams in cell 2, wherein there is 2 wave beams to change uplink waveform, in addition 3 without changing uplink Waveform, in this case, pH value and Pcmax value comprising 2 wave beams in 3 wave beams and cell 2 in cell 1 in PHR, Or the pH value comprising 3 wave beams in cell 1 and 2 wave beams in cell 2.

2, all wave beams in the cell of uplink waveform have been converted in the cell of UE；

For example, sharing 5 wave beams in cell 1, wherein there is 3 wave beams to change uplink waveform, in addition 2 do not change uplink Waveform includes the pH value and Pcmax value of 3 wave beams in this case, in PHR.As long as that is, there is a wave beam in cell Uplink waveform is changed, just the pH value and Pcmax value comprising all wave beams in the cell in PHR.

Equally, converted in the cell of UE uplink waveform cell can with only one, can also have it is multiple, if having more A, then UE can report the pH value of all wave beams in this multiple cell.

3, in the cell of UE wave beam signal strength be more than second signal preset threshold wave beam；

The scheduling strategy of base station configuration, can be the strong wave beam of preferential selection signal, therefore, can be preferential when reporting PHR Report the stronger wave beam of the signal strength of wave beam in the cell of UE.For example, signal strength is more than the small of third signal preset threshold Area.

The third signal preset threshold of a signal strength for wave beam can be pre-configured to UE by base station, reports PH When value, only report the signal strength of wave beam in the cell of UE more than the pH value of the wave beam of third signal preset threshold, other signals Intensity is not above the wave beam of third signal preset threshold, then does not report pH value.

In such cases, the wave beam that signal strength is more than third signal preset threshold is contained only in the PHR that UE is reported PH value and Pcmax value, or contain only pH value of the signal strength more than the wave beam of third signal preset threshold.

Intelligible, signal strength can be the signal quality parameters such as RSRP or RSRQ.

4, in the cell of UE wave beam signal strength be lower than fourth signal preset threshold wave beam；

Base station can consider: smaller by being limited when beam allocation ascending resource stronger to signal strength；It is right It is bigger by being limited when signal strength weaker beam allocation ascending resource.So base station can be excellent with configuration strategy The PH for the wave beam for first reporting signal strength weak.

Similarly, a fourth signal preset threshold can be pre-configured to UE by base station only report UE's when reporting pH value For signal strength lower than the pH value of the wave beam of fourth signal preset threshold, other signal strengths are more than that fourth signal presets threshold in cell The wave beam of value, then do not report pH value.

In such cases, wave beam of the signal strength lower than fourth signal preset threshold is contained only in the PHR that UE is reported PH value and Pcmax value, or the only cell pH value comprising signal strength more than fourth signal preset threshold.

In addition, the 4th kind of mode includes reporting signal strength higher than the PH of the beam of third signal preset threshold, also include Report signal strength lower than the PH of the beam of fourth signal preset threshold.It should be appreciated by those skilled in the art that above two Way combines, and also belongs to protection scope of the present invention.That is: signal strength in the cell of UE is reported to be higher than third signal preset threshold Beam PH and report the PH of the beam lower than fourth signal preset threshold.

5, signal strength strongest one or N number of wave beam in each cell of UE；

Specifically, the pH value of highest one or the N number of wave beam of RSRP value in each cell of UE can be reported only；It can also be with Only report the pH value of highest one or the N number of cell of RSRQ value in each cell of UE.It is intelligible, the strongest N of signal strength A wave beam refers to that signal strength is by weak sequence is arrived by force in the cell of UE, comes N number of wave beam of foremost.

It is directed to that " network configuration is to some UE and the wave that has activated with wave beam it is worth noting that, described above Beam ", if some UE can have 8 uplink beams, but current base station is only configured with 5 uplink beams, in this 5 wave beams, Only 3 are activation wave beams, then just for the uplink beam of activation in PHR.

6, one or the N number of wave beam that signal strength is most weak in the cell of UE；

In this way, the PH of can only report that signal is most weak in the cell of UE one or N number of wave beam.Specifically, The PH of RSRP value or RSRQ value minimum one or N number of wave beam can only be reported.It is intelligible, the most weak N number of wave of signal strength Beam refers to that signal strength is by weak sequence is arrived by force in the cell of UE, comes rearmost N number of wave beam.

In such cases, contained only in the PHR that UE is reported signal strength most weak one or N number of wave beam pH value and Pcmax value, or, containing only the pH value of signal strength most weak one or N number of wave beam.

It should be understood that 6 kinds enumerated above only report the mode of the pH value of part wave beam merely illustrative and non-limiting.

In the embodiment of the present invention, when using wave beam as Granular Computing pH value, UE can only report current important portion The pH value of the pH value of partial wave beam, remaining wave beam wouldn't report, and therefore, can reduce under the premise of not influencing the scheduling to UE The size of PHR, to save radio resource.

It in practical applications, can also be with the son in cell other than in addition to above-mentioned using cell or wave beam as Granular Computing PH Bandwidth (sub-band) is Granular Computing PH.

Such as: the cell of big bandwidth can be configured for UE in NR, for example 400MHz, UE be in so big bandwidth, respectively The uplink waveform that a sub- bandwidth uses may be different.Specifically, waveform change can be using subband width as granularity (per sub-band's).Several sub-band can be configured to a cell in advance by base station, each sub-band has been matched Set a sub-band ID；The width that each sub-band can also be set in advance by agreement, when bandwidth of cell is greater than one When sub-band, without configuration, UE voluntarily determines the frequency domain of each sub-band, and by sequence from low to high (may be reversed sequence) determines each sub-band ID.

As shown in figure 4, each sub- of all serving cells (cell of uplink activation) in the PHR that UE is generated including UE The pH value of band, the PH of a sub-band refer to the wide data sending instant in PUSCH or PUCCH of the subband of the cell Power headroom.The meaning of the c1 to c7, P, V, type1 and type2 in PHR format in Fig. 4 can be referred to and be described in Fig. 2. In Fig. 4, each cell is wide (sub-band 1 and sub-band 2) there are two subband, and each cell has reported two sub- bandwidth PH value, each subband is wide oneself independent pH value.It is with one Pcmax of each cell for Pcmax, shown in Fig. 4 For value, in fact, being also possible to that each subband is wide to report a Pcmax.

In the case where being to report granularity with subband width, if triggering a PHR, UE can report all cells every time The wide pH value of all subbands, such as: PHR shown in Fig. 4 contains the wide pH value of each subband of each cell of UE.

Sometimes, the pH value that can also only report the part subband in the cell of UE wide.It should be understood that in the cell of UE Part subband width may is that the part subband of each cell of UE is wide, the part subband for being also possible to the cell portion of UE is wide.

At this point, UE, which can be reported, thinks current important, it should report the subband of the cell of pH value wide.For residue Do not report the subband of the cell of PH wide, then it is assumed that the subband of these cells is wide not to be reported currently, and the scheduling to the UE is nor affected on.

It therefore, can only include the part subband of the cell of UE wide pH value and Pcmax in the embodiment of the present invention, in PHR Value, or the only wide pH value of part subband of the cell comprising UE.Wherein, the part subband width in the cell of UE can be following What is one or more:

1, the subband that uplink waveform has been converted in the cell of UE is wide；

Wherein, the cell of UE refers to all serving cells (cell of uplink activation) of UE.Certain subband of certain cell is wide Uplink waveform can transform to waveform B from waveform A, be also possible to transform to waveform A from waveform B.It has been converted in the cell of UE The subband of traveling wave shape is wide can also have multiple with only one.

In such cases, the wide pH value and Pcmax of subband for having converted uplink waveform is contained only in the PHR that UE is reported Value, or, only comprising having converted the wide PH of the subband of uplink waveform.

For example, sharing 5 sub- bandwidth in cell 1, wherein there is 3 sub- bandwidth to change uplink waveform, in addition 2 do not have Change uplink waveform, shares 5 sub- bandwidth in cell 2, wherein there are 2 sub- bandwidth to change uplink waveform, in addition 3 do not have Change uplink waveform, in this case, the PH in PHR comprising 3 sub- bandwidth in cell 1 and 2 sub- bandwidth in cell 2 Value and Pcmax value, or the pH value comprising 3 sub- bandwidth in cell 1 and 2 sub- bandwidth in cell 2.

2, all subbands converted in the cell of UE in the cell of uplink waveform are wide；

For example, sharing 5 sub- bandwidth in cell 1, wherein there is 3 sub- bandwidth to change uplink waveform, in addition 2 do not change Uplink waveform includes the pH value and Pcmax value of 3 sub- bandwidth in this case, in PHR.As long as that is, having one in cell A sub- bandwidth changes uplink waveform, just includes all subbands are wide in the cell pH value and Pcmax value in PHR.

Equally, converted in the cell of UE uplink waveform cell can with only one, can also have it is multiple, if having more PH value a, then that UE can report all subbands in this multiple cell wide.

3, the signal strength of the cell neutron bandwidth of UE is more than that the subband of the 5th signal preset threshold is wide；

It can be pre-configured a 5th signal preset threshold for the wide signal strength of subband, when reporting pH value, only Report the cell neutron bandwidth of UE signal strength be more than the 5th signal preset threshold the wide pH value of subband, other signal strengths The subband for being not above the 5th signal preset threshold is wide, then does not report pH value.

In such cases, contained only in the PHR that UE is reported signal strength be more than the 5th signal preset threshold subband it is wide PH value and Pcmax value, or contain only the wide pH value of subband that signal strength is more than the 5th signal preset threshold.

Intelligible, signal strength can be the signal quality parameters such as RSRP or RSRQ.

4, the signal strength of the cell neutron bandwidth of UE is wide lower than the subband of the 6th signal preset threshold；

Similarly, a 6th signal preset threshold can be pre-configured to UE by base station only report UE's when reporting pH value The signal strength pH value wide lower than the subband of the 6th signal preset threshold in cell, other signal strengths are more than that the 6th signal is default The subband of threshold value is wide, then does not report pH value.

In such cases, it is wide lower than the subband of the 6th signal preset threshold that signal strength is contained only in the PHR that UE is reported PH value and Pcmax value, or only comprising signal strength be more than the 6th signal preset threshold cell pH value.

5, in the cell of UE signal strength it is strongest one or N number of subband it is wide；

Specifically, RSRP value in each cell of UE highest one or the wide pH value of N number of subband can be reported only；It can also The pH value of RSRQ value highest one or N number of cell in each cell only to report UE.

It should be understood that the mode for the 4 kinds of pH values for only reporting part subband wide enumerated above is merely illustrative and non-limiting.

6, signal strength is most weak in the cell of UE one or N number of subband it is wide；

In this way, one that can only report that signal is most weak in the cell of UE or the wide PH of N number of subband.Specifically , it can only report RSRP value or RSRQ value minimum one or the wide PH of N number of subband.It is intelligible, the most weak N of signal strength A sub- bandwidth refers to that signal strength is by weak sequence is arrived by force in the cell of UE, and it is wide to come rearmost N number of subband.

In such cases, contained only in the PHR that UE is reported signal strength most weak one or the wide pH value of N number of subband and Pcmax value, or, containing only signal strength most weak one or the wide pH value of N number of subband.

, can be using subband width as Granular Computing pH value in the embodiment of the present invention, UE can report all sons of all cells The pH value of bandwidth, the pH value that can also only report current important part subband wide, can be in the wider field of subdistrict frequency band Under scape, pH value is flexibly reported.

In practical applications, PH can also be reported by granularity of cell group.It is one small when reporting PH as granularity using cell group The PH of the practical beam that can be one of cell pH value in the cell group or in which a cell of the corresponding pH value of district's groups Value.

For example, the corresponding pH value of a cell group, can be following one of several:

1, it can be the PH of the strongest cell of signal strength in the cell group.Intelligible, signal strength can be The signal quality parameters such as RSRP or RSRQ.

2, it can be the pH value of the main plot (PCell) in the cell group.

3, it can be the pH value of the smallest cell of cell index in the cell group.

4, it can be the pH value of the strongest beam of signal strength in the cell group.

It should be understood that the pH value for the 4 kinds of cell groups enumerated above is merely illustrative and non-limiting.

If there are multiple cell groups in the cell of UE, the pH value of whole cell groups can be reported, can also only report part The pH value of cell group.

The embodiment of the invention also provides the methods that a kind of base station instruction UE carries out waveform convertion.Below with reference in Fig. 5 The base station instruction UE method for carrying out waveform convertion is introduced in information exchange flow chart.

501, base station sends instruction message to UE.

Specifically, instruction message is used to indicate the target uplink waveform of UE.

Base station may is that by sending instruction message to UE to change the condition of the uplink waveform of UE

When the distance between UE and base station change, signal strength is more and more weaker, when less than certain signal strength threshold, Base station thinks to need to change the uplink waveform of UE, then passes through instruction message and UE is notified to convert uplink waveform.As long as base Think to change UE one or more cells or subband are wide or beam or when the uplink waveform of cell group, all in station Instruction message notice UE can be sent and change uplink waveform.

502, UE changes uplink waveform according to instruction message.

UE receives the instruction message that base station is sent, when the target uplink waveform indicated in instruction message is different from the current institute of UE When uplink waveform (the first uplink waveform) used, UE is by uplink waveform from the first uplink waveform convertion to the target upgoing wave Shape.

It will be understood to those skilled in the art that UE sent to base station PHR format, trigger in the case of which kind of PHR or Information that PHR is carried, content can be held independent of the interaction between UE and base station, such as transmitting of instruction message, instruction message The information or content of load.In other words, it is related to the associated description of PHR, can be carried out based on PHR as an independent technique scheme Protection.Equally, based on the associated description of instruction message, it can also be used as an independent technique scheme and protected.Certainly, it is related to The foregoing description of PHR can also interaction based on instruction message or its particular content format etc., which is not limited by the present invention.

It may include in following methods in the instruction message that base station is sent to UE based on embodiment shown in fig. 5 Content in any mode:

The first: instruction message that base station is sent to UE instruction UE converts uplink waveform, specifically, can be in instruction message Target uplink waveform is not carried, UE is triggered by instruction message and converts waveform, after UE receives the instruction message, converts upgoing wave Shape.

Such as: if the currently used uplink waveform of UE is the first uplink waveform, after UE receives the instruction message, by the One uplink waveform convertion is at target uplink waveform.

Second: base station may include the target uplink waveform of UE into the instruction message that UE is sent, and base station can lead to Instruction message instruction UE is crossed by the uplink waveform convertion of all cells to target uplink waveform.

The third: base station may include Target cell ID and Target cell ID corresponding into the instruction message that UE is sent Target uplink waveform, base station can indicate UE by the uplink waveform convertion of the corresponding cell of Target cell ID by the instruction message At target uplink waveform.

4th kind: including Target cell group ID and the corresponding mesh of Target cell group ID in the instruction message that base station is sent to UE Traveling wave shape is put on, base station can indicate that UE is small by each of the corresponding cell group of Target cell group ID by the instruction message The uplink waveform convertion in area is at target uplink waveform.

5th kind: including subband included by Target cell ID, Target cell ID in the instruction message that base station is sent to UE The corresponding target uplink waveform of the wide ID and wide ID of subband, base station can indicate that UE is corresponding by the wide ID of subband by the instruction message The wide uplink waveform convertion of subband is at target uplink waveform.

6th kind: including wave beam included by Target cell ID, Target cell ID in the instruction message that base station is sent to UE The corresponding target uplink waveform of ID and wave beam ID, base station can indicate UE by the corresponding wave beam of wave beam ID by the instruction message Uplink waveform convertion is at target uplink waveform.

The target uplink waveform in instruction message in second to the 6th kind situation, it may also be said at being that UE is allowed to be transformed into Target uplink waveform.Because only that two kinds of waveforms, so it can be appreciated that " transformation uplink waveform ".

7th kind: in the instruction message that base station is sent to UE including UE the corresponding uplink indicating bit of each cell (such as Bitmap), when the corresponding uplink indicating bit of some cell is the first value, instruction UE converts the uplink waveform of the cell.

8th kind: including the corresponding uplink indicating bit (example of each cell group of UE in the instruction message that base station is sent to UE Such as bitmap), when the corresponding uplink indicating bit of some cell group is the first value, instruction UE converts each of the cell group The uplink waveform of cell.

9th kind: the Target cell ID and Target cell ID in the instruction message that base station is sent to UE including UE are corresponding The corresponding indicating bit of each wave beam in cell, when indicating bit is the first value, the corresponding wave beam of instruction UE transformation indicating bit Uplink waveform.

7th kind to nine kinds can be indicated with bitmap, with second of the front several formats for being included to the 6th kind Difference is: in the case of four kinds of front, can use bitmap only comprising cell portion/cell group/beam waveform instruction When, it is necessary to include all cells/cell group/beam waveform instruction.

Specifically, the instruction message can be media access control (the media access of MAC layer in base station Control, MAC) control unit (control elment, CE).MAC layer is scheduling physical layer work, and control function is passed through The course of work of entire physical layer is worn, the MAC PDU of encapsulation includes MAC subheader (size is variable) and MAC service from structure Data cell (service data unit, SDU) and MAC CE etc..

The MAC CE can there are several types of possible formats:

Format one:

As shown in fig. 6, only being indicated in MAC subheader, with a Logic Channel Identifier (logical channel Identity, LCH ID) mark, there is no MAC SDU.It is for becoming that MAC subheader in MAC CE, which is used to indicate the UE MAC CE, The message of traveling wave shape is changed, and indicates that UE will convert the uplink waveform of all cells.

After UE receives this MAC subheader, the uplink waveform being being currently used (the first uplink waveform) is changed into another kind Uplink waveform (target uplink waveform).It is available since only there are two types of uplink waveforms, so becoming any without explicit instruction UE Uplink waveform, it is only necessary to notify UE " changing uplink waveform ".After UE is received, all uplink cells used in oneself Waveform is changed to the specified uplink waveform in base station in transmission.

Format two:

As shown in fig. 7, being identified in MAC subheader with a LCH ID, show instruction UE by uplink waveform in MAC CE It is transformed to target uplink waveform (uplink waveform A or uplink waveform B).After UE is received, all uplink cells used in oneself Transmission in waveform is changed to the specified target uplink waveform in base station.

Such as the uplink waveform A/B in Fig. 7, it can indicate respectively that uplink waveform is that A or B certainly can also with " 0 " or " 1 " Whether to need to change with " 0 " or " 1 " instruction uplink waveform.

Under this format, due to the length of MAC CE be it is fixed, do not needed in MAC subheader instruction MAC CE length.

Format three:

As shown in figure 8, being identified in MAC subheader with a LCH ID, show instruction UE by uplink waveform in MAC CE It is changed to target uplink waveform (uplink waveform A or uplink waveform B).Specifically, waveform change can be using cell as granularity, I.e. base station indicates UE by the uplink waveform convertion of some cell at waveform A or waveform B.

Under this form, base station may only change the uplink waveform of a part of cell used in UE.Such as the uplink in Fig. 8 Waveform A/B can indicate respectively that the uplink waveform of corresponding cell is A or B with " 0 " or " 1 ", it is of course also possible to " 0 " or Whether the uplink waveform of " 1 " instruction respective cell needs to change.

Under this format, due to the length of MAC CE be not it is fixed, need to indicate the length of MAC CE in MAC subheader, It include LCH ID and Length in MAC subheader.

Format four:

As shown in figure 9, being identified in MAC subheader with a LCH ID, show instruction UE by uplink waveform in MAC CE It is changed to target uplink waveform (uplink waveform A or uplink waveform B).Specifically, waveform change can be using cell group as granularity , i.e., base station pre-configured some or multiple cells belongs to the same cell group, and configures a cell group ID.When base station is thought to need to change the uplink waveform of certain cell group, UE is indicated with MAC CE, by some cell The uplink waveform of group is changed to A or B.

Under this form, base station may only change the uplink waveform of a part of cell group used in UE.As upper in Fig. 9 Traveling wave shape A/B can indicate respectively that the uplink waveform of corresponding cell group is A or B with " 0 " or " 1 ", it is of course also possible to Whether the uplink waveform of " 0 " or " 1 " instruction respective cell group needs to change.

Equally, under this format, due to the length of MAC CE be not it is fixed, need to indicate MAC CE in MAC subheader Length, include LCH ID and Length in MAC subheader.

Format five:

As shown in Figure 10, it in MAC subheader, is identified with a LCH ID, shows instruction UE by upgoing wave in MAC CE Deformation more uplink waveform A or B.Due to can configure the cell of big bandwidth in NR for UE, for example 400MHz, UE are so big In bandwidth, the uplink waveform of each wide use of subband may be different.Specifically, waveform change can be with sub- Band is granularity, i.e., base station has configured several sub-band to a cell in advance, configures one to each sub-band sub-band ID.When base station is thought to need to change the uplink waveform of certain sub-band, UE is indicated with MAC CE, it will be a certain The uplink waveform of certain sub-band of a cell is changed to A or B.

Under this form, base station can only change the uplink waveform of a part of sub-band used in UE, such as Figure 10 In uplink waveform A/B, can indicate respectively that the wide uplink waveform of corresponding subband is A or B with " 0 " or " 1 ", certainly, It can indicate whether the wide uplink waveform of corresponding subband needs to change with " 0 " or " 1 ".

Format six:

As shown in figure 11, on the basis of format five, some optimizations, such as multiple sub- of the same cell can be carried out Band shares an ID.In each cell, UE has several sub-band available on earth, be it is configured by base station in advance, each The quantity of the available sub-band of UE, base station and UE both sides both know about in cell, so, without indicating sub- in MAC CE The quantity of band.

Each sub-band of each cell indicates that corresponding uplink waveform is A or B with " 0 " or " 1 ".Certainly, It can also indicate whether the wide uplink waveform of corresponding subband needs to change with " 0 " or " 1 ".

Format seven:

As shown in figure 12, it in MAC subheader, is identified with a LCH ID, shows instruction UE by upgoing wave in MAC SDU Deformation more uplink waveform A or B.Specifically, the waveform change of each cell is indicated with a bit map, each bit generation One cell of table indicates that the waveform of respective cell needs to change if the bit is " 1 ", if the bit is " 0 ", expression pair The waveform of cell is answered to have no need to change.In this way, waveform change is using cell as granularity, i.e., base station can flexibly refer to Show that the uplink waveform of some cell is changed to A or B by UE.

Bit map in above-mentioned MAC CE may include all " cells being configured " of UE, can also only include All " have been configured with, and had the cell of up-link carrier " of UE also may include that all of UE " have been configured, and have located In the cell of activated state "；It also may include that all of UE " have been configured, and have had up-link carrier, and is in activated state small Area ".

It is worth noting that, the mode of above-mentioned bit map is also applied for cell group (cell group), i.e., each cell Mono- bit of group；It is also applied for cell sub-band, i.e., each mono- bit of cell+sub-band, as long as base station and UE Made an appointment which cell+sub-band share a bit, so that it may use the format.

Format eight:

As shown in figure 13, it in MAC subheader, is identified with a LCH ID, shows instruction UE by upgoing wave in MAC SDU Deformation more uplink waveform A or B.Specifically, the waveform change of each cell is indicated with a bit map, each bit generation One cell of table indicates that the waveform of respective cell is " uplink waveform A ", if the bit is " 0 ", table if the bit is " 1 " The waveform for showing respective cell is " uplink waveform B ".

In this way, waveform change be using cell as granularity, i.e., base station can flexibly indicate UE by some The uplink waveform of cell is changed to A or B.After UE is received, to each cell, determine the uplink waveform that is indicated in MAC CE whether with Present uplink waveform currently in use is consistent, if it is inconsistent, update, if unanimously, without processing.

It is worth noting that, the mode of above-mentioned bit map is also applied for cell group (cell group), i.e., each cell Mono- bit of group；It is also applied for cell sub-band, i.e., each mono- bit of cell+sub-band.

Format nine:

As shown in figure 14, it in MAC subheader, is identified with a LCH ID, shows instruction UE by upgoing wave in MAC SDU Deformation more uplink waveform A or B.Specifically, to each cell, each wave beam in the cell is indicated with a bit map Uplink waveform.Each bit represents a wave beam, if the bit is " 1 ", indicates that the waveform of corresponding wave beam is " uplink waveform A " indicates that the waveform of corresponding wave beam is " uplink waveform B " if the bit is " 0 ".

In this way, waveform change be using wave beam as granularity, i.e., base station can flexibly indicate UE by some The uplink waveform of some wave beam of cell is changed to A or B.After UE is received, to each wave beam of each cell, determine Whether the uplink waveform indicated in MACCE is consistent with present uplink waveform currently in use, if it is inconsistent, update, if Unanimously, then without processing.

In example shown in Figure 14, it is assumed that each cell is configured with 6 wave beams, and each wave beam corresponds to a bit, if Corresponding bit is 1, indicates the upgoing wave deformation more " uplink waveform B " of the wave beam, if corresponding bit is 0, indicates the wave beam Upgoing wave deformation more " uplink waveform A ".

Due to that only there are two types of possible uplink waveform, can also indicate that the uplink waveform of corresponding wave beam is changed with " 1 ", " 0 " indicates that the uplink waveform of corresponding wave beam is constant.

It is worth noting that, all assuming that MAC subheader-MAC in example represented by format one to format nine above SDU-MAC subheader-MAC SDU ..., in fact, MAC subheader and MAC SDU can also be put by the way of concentrating, such as Figure 15 institute The mode of the MAC subheader 1-MAC subheader 2-MAC subheader 3-MAC SDU 1-MAC SDU 2-MAC SDU 3 shown.For format one Described in " do not have the corresponding MAC subheader of MAC SDU ", can be placed on before other MAC subheaders, others can also be placed on Behind MAC subheader, it is included in the protection scope of this programme.No matter the data structure of any MAC PDU is taken, not shadow Ring technical spirit.

Figure 6 above is to indicate that UE converts uplink waveform by the MAC CE of MAC layer to Figure 14, in addition, base station can also lead to It crosses downlink control message (down link information, DCI) notice UE and becomes uplink waveform.

Optionally, target uplink waveform can be directly carried in DCI, after UE receives DCI message, if UE is currently made When the target uplink waveform carried in uplink waveform and DCI message is not identical, UE is by uplink waveform convertion to target uplink Waveform.

As shown in figure 16, base station uses DCI to distribute ascending resource for UE, while notifying UE, sends number with uplink waveform A According to UE sends data using uplink waveform A.When it is that UE distributes ascending resource that subsequent base stations, which reuse DCI, UE uplink is notified Waveform B is sent, at this point, the uplink waveform indicated in UE discovery DCI is changed, uplink waveform is converted into wave from waveform A Shape B.

It is the introduction that the mode of waveform convertion is carried out to the base station instruction UE in the embodiment of the present invention above.Further, exist In the embodiment of the present invention, waveform convertion can be used as a kind of triggering mode that UE triggering PHR is reported.Below with reference to base station in Figure 17 The waveform convertion triggering PHR process reported is introduced in information exchange process between UE.

1701, base station sends instruction message to UE.

1702, when the first uplink waveform used in target uplink waveform is different from UE, UE is by uplink waveform from first Uplink waveform convertion is to target uplink waveform.

Base station sends instruction message to UE, is used to indicate the target uplink waveform of the UE, and UE becomes according to the instruction message Change traveling wave shape.

But it should be noted that being using base station notice UE transformation waveform as on UE triggering PHR in embodiment shown in Figure 17 A kind of triggering mode of report, information, the content that the instruction message that base station is sent in embodiment shown in Figure 17 is carried are disobeyed Rely the content of the instruction message described in Fig. 6 to Figure 15, it can be using the format (figure of the previously described instruction message of the application 6 to embodiment shown in figure 15), format described in Fig. 6 to embodiment shown in figure 15 can not also be used.In other words, Fig. 6, based on the associated description of instruction message, can be used as an independent technique scheme and protected into Figure 15.

1703, UE triggers PHR.

No matter using any format instruction waveform change, as long as UE discovery base station indicates some cell, some sub- Band, some beam or the uplink waveform of some cell group need to change, and just trigger PHR.Once PHR is triggered, if subsequent UE It gets ascending resource (can be and get UL grant), and priority of logical channels (logical channel Prioritization, LCP) allow, UE can send PHR to base station.

Specifically, the process for sending PHR to base station is as follows after UE triggering PHR:

Base station is that the UE distributes uplink transmission resource, and base station passes through Physical Downlink Control Channel (physical downlink Control channel, PDCCH) to UE send multi-upstream access authorization (uplink grant, UL grant), the UL grant Including modulation coding scheme (modulation and coding scheme, MCS), Physical Resource Block (physical Resource block, PRB) etc. information, the UL grant tell UE can in which carrier wave transmitting data of which time, with And the Modulation and Coding Scheme used, so that UE accurately transmits data.It is that the UE first distributes a small part by the UL grant Physical resource, such as PHR and/or Buffer Status Report (buffer status report, BSR) are reported for UE enough.

The physical layer of UE reads the information in UL grant after being successfully received UL grant, and construction includes PHR's Medium Access Control (MAC) Protocol Data Unit (protocol data unit, PDU), is then transferred to physical layer for MAC PDU.

UE is reported by physical layer physical resource according to indicated by the UL grant received and MCS to base station MACPDU, so that base station can reasonably distribute the transmission of upstream data next time according to the PHR that UE is reported for the UE Resource.

It should be noted that the format of the PHR reported is unlimited herein, described in the embodiment of the present invention can be used A kind of PHR format of anticipating reports, and can report all or part of cell pH value, the pH value of all or part of wave beam, all or part The pH value of the wide pH value of subband, all or part of cell group.

It will be understood to those skilled in the art that related PHR format (corresponds to please see Fig. 2 to Fig. 4 before the application Embodiment part) or the PHR information, the content that are carried can be independent of the wave described in embodiment shown in Figure 17 The trigger condition of fractal transform.In other words, this application involves PHR associated description, can based on PHR as an independent skill Art scheme is protected.Certainly, the description of PHR involved by the application can also interaction based on instruction message or its particular content Format etc., which is not limited by the present invention.

1704, base station receives PHR.

It should be noted that when UE sends PHR to base station in step 1703, not necessarily to the base for sending instruction message It stands transmission, is also possible to send the PHR to multiple base stations that UE provides service simultaneously.Therefore, the base of PHR is received in step 1704 Signified base station in not necessarily step 1701 of standing.

On the one hand, the uplink waveform indicating means in the embodiment of the present invention can be referred to by the instruction information of different-format Show the wave beam in the cell or cell of UE or the subband in cell be wide or cell group changes uplink waveform, so as to according to Different granularities changes the uplink waveform of UE, meets diversified communication requirement and application scenarios in 5G.

On the other hand, in the embodiment of the present invention, the change of the waveform of UE can trigger PHR and report, and make base station in the wave of UE The newest pH value of UE can be known after fractal transform at once, so that base station be enable to carry out efficient scheduling to UE.

On the other hand, reporting for the PHR in the embodiment of the present invention can support different formats, and different reports granularity: Can or cell group wide using cell or wave beam or subband reported as granularity.It is answered so as to meet the diversified of 5G With scene and demand.

On the basis of the embodiment shown in Figure 17, UE, can also be according to instruction after receiving the instruction message of base station The particular content of message reports corresponding PHR.It is illustrated below:

It, can be with when the PHR that UE is reported 1, if instruction message is the MAC CE format in above-mentioned format three (shown in Fig. 8) The pH value and Pcmax value of all cells in a PHR comprising UE；It can also be in a PHR only comprising having converted uplink The pH value and Pcmax value of the cell of waveform；The band where having converted the cell of uplink waveform can also be included in a PHR The pH value and Pcmax value of interior all cells.

2, if instruction message is the MAC CE format in above-mentioned format four (shown in Fig. 9), when UE reports PHR, Ke Yi The pH value and Pcmax value of all cells in one PHR comprising UE, can also be in a PHR only comprising having modified upgoing wave The pH value and Pcmax value of those of cell group of shape cell.

3, if instruction message is the MAC CE format in above-mentioned format five (shown in Figure 10), when UE reports PHR, Ke Yi The pH value and Pcmax value of all sub-band of all cells in one PHR comprising UE can also only wrap in a PHR PH value and Pcmax value containing the sub-band for having modified uplink waveform, can also be in a PHR only comprising having modified upgoing wave The pH value and Pcmax value of all sub-band of the cell of shape.

4, if instruction message is the MAC CE format in above-mentioned format six (shown in Figure 11), when UE reports PHR, Ke Yi The pH value and Pcmax value of all sub-band of all cells in one PHR comprising UE.It can also only be wrapped in a PHR PH value and Pcmax value containing the sub-band for having modified uplink waveform.It can also be in a PHR only comprising having modified upgoing wave The pH value and Pcmax value of all sub-band of the cell of shape, that is to say, that as long as there is a sub-band to change in cell Uplink waveform just includes the pH value and Pcmax value of all sub-band in the cell in PHR.

5, if instruction message is the MAC CE format in above-mentioned format seven (shown in Figure 12) or format eight (shown in Figure 13), It can include the pH value and Pcmax value of all cells of UE in a PHR when UE reports PHR；It can also be in a PHR It only include the pH value and Pcmax value for having modified the cell of uplink waveform；It can also be in a PHR comprising having modified uplink waveform Cell where Band, all cells in the band all report pH value and Pcmax value.

6, if instruction message is the MAC CE format in above-mentioned format nine (shown in Figure 14), when UE reports PHR, Ke Yi The pH value and Pcmax value of all wave beams of all cells in one PHR comprising UE, or all wave beams comprising all cells PH value.It only can also include the pH value and Pcmax value for having modified the wave beam of uplink waveform in a PHR.It can also be one It only include the pH value and Pcmax value for having modified all wave beams of cell of uplink waveform in a PHR, that is to say, that as long as cell There is a wave beam to change uplink waveform in as soon as, pH value and Pcmax value comprising all wave beams in the cell in PHR.

Further, in the application, the pH value calculated under two kinds of waveforms can be reported, that is, is reported according to uplink waveform The calculated pH value of A and according to the calculated pH value of uplink waveform B.It can also only report and be calculated under currently used waveform The PH come.

Using the wave beam in cell, cell, the subband in cell is wide or cell group is Granular Computing pH value when, if having need It wants, the pH value under two kinds of waveforms can be reported.

Specifically, in the PHR that UE is reported, either reporting the PH of whole cells when using cell as Granular Computing pH value The pH value of value or cell portion, the pH value of any cell can include the pH value calculated according to waveform A and waveform B, It is also possible to only include the pH value gone out according to the waveshape being being currently used.

Each cell shown in Figure 18 for UE all reports a kind of PHR format sample of two pH values.With the difference of Fig. 2 It is, each cell all corresponds to a pH value (PH A) calculated according to uplink waveform A and calculated according to uplink waveform B PH value (PH B) out.

Specifically, either reporting each of each cell of UE when using the wave beam in cell as Granular Computing pH value The pH value of wave beam still reports the pH value of the part wave beam in the cell of UE all may be used for any wave beam of any cell To include the pH value calculated according to waveform A and waveform B, it is also possible to only include the waveshape according to being being currently used PH value out.

Each beam shown in Figure 19 for UE reports a kind of PHR format sample of two pH values.With the difference of Fig. 3 It is, each beam of each cell corresponds to a pH value (PH A) calculated according to uplink waveform A and according to upper The pH value (PH B) that row waveform B is calculated.

Specifically, either reporting the every of each cell of UE when using the subband width in cell as Granular Computing pH value The pH value of a sub- bandwidth, the pH value for still reporting the part subband in the cell of UE wide, for any cell any wave beam all It may include being also possible to only include the wave according to being being currently used according to the pH value calculated according to waveform A and waveform B The calculated pH value of shape.

Under the conditions of following several, the pH value under two kinds of waveforms can be reported, in order to which base station is according to both pH values pair UE carries out efficient scheduling, or instruction UE converts uplink waveform.

It should be noted that it is following it is several under the conditions of in waveform convertion can be and triggered by various conditions, Ke Yiyu Waveform convertion trigger condition in the application Fig. 5 or embodiment illustrated in fig. 17 is unrelated.

It 1, may include the pH value under two kinds of waveforms after UE converts waveform, in the PHR that reports.

After UE receives MAC CE notice waveform change, two can also be reported on the basis of embodiment shown in Figure 17 The pH value calculated under kind waveform, this special PHR format are disposably, only to receive first time after waveform change PHR, which is reported, just needs to report two pH values, and subsequent PHR is reported, and only reports a pH value.Or after receiving waveform change PHR, which is reported, in a period of time just needs to report two pH values.The length of period is pre-configured by base station.

In fact, the pH value under two kinds of waveforms only can also be reported to a part of cell (first community), another part is small Area's (second community) then reports the pH value under a kind of waveform.Specifically it may is that

(1) pH value under two kinds of waveforms is only reported to the cell for changing uplink waveform.

(2) which cell change uplink waveform, just reports under two kinds of waveforms the cell in the bandwidth where the cell PH value, remaining then only reports the pH value under current form.

(3) all cells in the cell group where the cell are just reported two kinds by which cell change uplink waveform PH value under waveform, remaining then only reports the pH value under current form.

Similarly, in fact, the pH value under two kinds of waveforms, another portion only can also be reported to a part of wave beam (the first wave beam) Partial wave beam (the second wave beam) then reports the pH value under a kind of waveform.Specifically it may is that

(1) pH value under two kinds of waveforms is only reported to the wave beam for changing uplink waveform.

(2) all wave beams in the cell are just reported the pH value under two kinds of waveforms by which cell change uplink waveform, Remaining then only reports the pH value under current form.

It similarly, can also be only to the subband for changing uplink waveform using subband width as Granular Computing pH value Width, or change all subband width in the cell of uplink waveform and report pH value under two kinds of waveforms, remaining is then only reported currently PH value under waveform.

2, UE judges whether to report the pH value under two kinds of waveforms according to path loss.

The 1st kind of condition for reporting the pH value under two kinds of waveforms is after the waveform change of UE, to report the PHR of two kinds of pH values.It is real On border, a path loss section can also be configured by base station, when UE discovery downlink path loss is located at this section, if in this section PHR is sent, then reports the PHR comprising the pH value under two kinds of waveforms, otherwise only reports the PHR comprising the pH value under current form.

As shown in figure 20, in step 2001, base station configures a path loss section, and the path loss section of configuration is sent to UE；In step 2002, UE triggers PHR；Step 2003, UE judges whether current path loss is located at the path loss area of base station configuration Between, if being located at the path loss section of base station configuration, into the PHR that base station reports comprising under two kinds of waveforms in step 2004 PH value.

In addition, scheduling of the application for accurate optimization base station, introduces filling (padding) PHR.Process is reported in PHR In, if after all data in existing caching (buffer) are all put into transmission resource block by UE discovery, can't fill entire The UL grant distributed in step 202 or step 207 to UE then generates a padding PHR, is reported to base station.

If UE has found that remaining ascending resource can not put down entire PHR, just PHR is truncated, reports a short PHR. As to how truncate, it can be just like under type:

1, remove Pcmax.

2, reporting pH value by way of granularity using cell group in the application.

3, by reporting cell portion or part wave beam or the wide mode of part subband to report PH in the application.

4, the case where reporting the pH value of two kinds of waveforms if necessary reports the pH value under a kind of waveform, only then with oneself Based on the uplink waveform being being currently used, calculated PH is then reported, calculated pH value under another waveform, not on Report.

By way of such introducing padding PHR, the ascending resource that base station can be made full use of to distribute, so as to Avoid the waste of air interface transmission resource.
