Under the mixed networking of grand micro-station, Micro eNB(Micro evolved NodeB, micro-station) the UE(User Equipment in community, subscriber equipment) easily to Macro eNB(Macro evolved NodeB, macro station) UE in community causes interference, like this, the SINR(Signal to Interference plus Noise Ratio that has caused the subscriber equipment of macro station, the dry ratio of letter) reduce, speed declines, community power control does not accomplish well to coordinate the interference of minizone under heterogeneous network, reduced the population size of community, can cause the mutual lifting of power of UE, it is larger that UE in Wei Zhan community sends out merit, to the UE in macro station community, disturb larger, the UE that can trigger in macro station community falls net and the network problems such as difficulty that network.
The embodiment of the present invention provides a kind of Poewr control method, as shown in Figure 1, comprising:
101, base station receives the power headroom reporting (PHR) of user equipment to report, and power headroom reporting (PHR) comprises the first transmitting power surplus of subscriber equipment.
Wherein, the base station is here the micro-station of Micro eNB, the UE in subscriber equipment Wei Weizhan community.UE can pass through MCE(MAC-Control Element, MAC Control Element) regularly to micro-station, report PHR(Power Headroom Report, power headroom reporting (PHR)).This PHR comprises the first transmitting power surplus of UE, the maximum transmission power that the first transmitting power surplus is UE and actual emission power poor.Wherein, MAC(Media Access Control, media interviews are controlled) for being responsible for, control and the physical medium that is connected physical layer.
The initiation of PHR is at PUSCH(Physical Uplink Shared Channel, Physical Uplink Shared Channel), when UE meets PUSCH transmission condition, just to base station, send PHR.The condition of initiating PHR can be divided into 3 kinds, and satisfied wherein any one condition can trigger and report.The one, prohibit timer(forbids timer) overflow, and path loss is caught up with path loss while once sending PHR and is compared its variable quantity and be greater than RRC(Radio Resource Control, Radio Resource control) the pathchange(path changing of configuration), the 2nd, periodic timer(periodical timer) overflow, the 3rd, UE receives RRC reallocation message, this message comprises phr config configuration, and UE need to comprise PHR when sending PUSCH for the first time.The condition here can, for other trigger condition, not limit here yet.Wherein, this PHR can account for 6 bit, can to base station, report once for 1s clock UE, also can, for setting At All Other Times, not limit here.
102, base station, according to the first transmitting power surplus in parameter preset and power headroom reporting (PHR), obtains the second transmitting power surplus.
Exemplary, eNB, after receiving the PHR that UE reports, deducts parameter preset Po by the transmitting power margin value in this PHR, obtains the second transmitting power surplus.Like this, at eNB, the PHR that UE reports has reduced, eNB just by the current transmitting power of UE false amplified, eNB is controlled, so that the transmitting power of UE reduces to the transmitting power of UE.
Wherein, the span of Po can be 0～23, for example, can be 0,13,16 etc.Need to by the emulation of network planning network optimization, get optimized parameter according to different scene (compact district, open area) etc., obtain the postiive gain of cell throughout.Optionally, the unit of the Po in various embodiments of the present invention is decibel (dB), hereinafter repeats no more.

Exemplary, can be by the protocol fields of eNB be changed or is increased, make eNB to UE, to send message by air interface, this message comprises parameter preset Po, be used for limiting the transmitting power of UE, make UE when receiving this parameter preset, can, according to the transmitting power surplus in the PHR of this parameter preset and UE, obtain the second transmitting power surplus.
Wherein, the second transmitting power surplus equals the first transmitting power surplus, or the second transmitting power surplus equals the poor of the first transmitting power surplus and parameter preset.When the first transmitting power surplus is subscriber equipment receipt message, the transmitting power surplus of subscriber equipment.
The maximum transmission power that the first transmitting power surplus is UE and actual emission power poor, it is the difference that maximum transmission power deducts actual emission power, when the second transmitting power is the difference of the first transmitting power surplus and parameter preset Po, the maximum transmission power of UE deducts the difference of parameter preset Po.The span of the Po value here can be 0～23, for example, can be 0,13,16 etc.Need to by the emulation of network planning network optimization, get optimized parameter according to different scene (compact district, open area) etc., obtain the postiive gain of cell throughout.If the PHR that UE reports as forward direction eNB is less than Po, the PHR that this UE reports to eNB comprises the first transmitting power surplus, the first transmitting power surplus of UE is not upgraded, and the second transmitting power surplus equals the first transmitting power surplus.
202, base station receives the power headroom reporting (PHR) of user equipment to report, and power headroom reporting (PHR) comprises the second transmitting power surplus.
Exemplary, when UE is getting after the parameter Po of eNB transmission, UE is when obtaining PHR, the difference that UE deducts parameter preset Po by the first transmitting power obtains the second transmitting power surplus, obtain the PHR after renewal, this PHR comprises the second transmitting power surplus of UE, and the PHR after upgrading is reported to eNB.
If the PHR that UE reports as forward direction eNB is less than Po, the PHR that this UE reports to eNB comprises the first transmitting power surplus, the transmitting power surplus of UE is not upgraded.
Wherein, the initiation of PHR is on PUSCH, when UE meets PUSCH transmission condition, just to base station, sends PHR.The condition of initiating PHR can be divided into 3 kinds, and satisfied wherein any one condition can trigger and report.The one, prohibit timer overflows, and the path loss that path loss is caught up with while once sending PHR is compared the pathchange that its variable quantity is greater than RRC configuration, the 2nd, periodic timer overflows, the 3rd, UE receives RRC reallocation message, this message comprises phr config configuration, and UE need to comprise PHR when sending PUSCH for the first time.The condition here can, for other trigger condition, not limit here yet.Wherein, this PHR can account for 6 bit, can to base station, report once for 1s clock UE, also can, for setting At All Other Times, not limit here.
203, base station is carried out power control according to the second transmitting power surplus to subscriber equipment.
Concrete, when eNB has obtained the second transmitting power surplus in the PHR after upgrading, under the constant condition of the power spectral density of UE, eNB can obtain according to the PHR after upgrading the RB(Resource Block that eNB is UE scheduling, Resource Block) quantity, then, eNB compares the second parameter preset of the RB quantity of this UE and eNB, if Resource Block quantity is less than the second parameter preset, base station sends power control commands word f (i) to subscriber equipment, and power control commands word is used to indicate subscriber equipment and reduces actual emission power.Wherein, the second parameter preset is relevant with number of users and the transmission bandwidth of this base station service, and the second parameter preset is determined according to number of users and the transmission bandwidth of service in base station.
Like this, can to UE, carry out power control adjusting by the control of eNB, the actual emission power of the UE in restriction Wei Zhan community, reduces the transmitting power of the UE in Wei Zhan community, reduce UE in the Wei Zhan community interference to the UE in macro station community, to promote the throughput of whole community.
And when RB quantity is greater than goal-selling value, eNB sends power control commands word to UE, this power control commands word is for the transmitting power of lifting UE.
Exemplary, as shown in Figure 3, when transmitting power headroom reporting UE being reported as eNB reduces different Po, the change in gain of two kinds of cell flows when macro station and micro-station mixed networking.Wherein, the throughput of flow when the baseline x of data is independent macro station networking, be made as Base, the gain of the throughput of overall throughput when y axle is grand micro-station common networking during with respect to the independent networking of macro station, specifically can be expressed as [(macro station throughput+micro-station throughput) the independent networking throughput of/macro station]-1.As can be seen from Figure 3, under the condition of grand micro-station common networking, the overall throughput of obtaining, with respect to the gain situation of Base, different and different from the value of Po parameter.When Po value 0,13,16,19 o'clock, micro-station is for the Power Limitation of UE, but the overall throughput at grand micro-station declines, when Po gets 23, micro-station further increases for the Power Limitation of UE, and micro-station UE disturbs less to macro station UE, make grand micro-station overall throughput be postiive gain.Wherein, the unit of Po is dB.
For example, when the Po at micro-station number is 0, micro-station and the mutual interference of macro station phase, under common networking condition, throughput when overall throughput is independent with respect to macro station has reduced 19.86%; When the Po at micro-station being set being 13 or 16, between grand micro-station, still exist and disturb, due to micro-station, for the maximum of UE, to send out merit limited amplitude larger, micro-station self throughput declines larger, making grand micro-station overall throughput is to have declined 32.71% at 13 o'clock with respect to Base at Po, at Po, is to have declined 32.81% at 16 o'clock; When the Po at micro-station being set being 19, micro-station is sent out merit limited amplitude to the maximum of UE and is further reduced, the throughput at micro-station self declines larger, but with respect to Po, is 13 or has reduced for 16 o'clock for the interference of macro station, and the overall throughput at grand micro-station has declined 26.58%; When the Po at micro-station being set being 23, micro-station increases for the Power Limitation of UE, and the throughput at micro-station self is declined, but now,, the UE at micro-station does not almost disturb the UE of macro station, like this, the throughput lifting that grand micro-station is overall 11.54%, produced postiive gain.Here the numerical value of Po and throughput is not specifically limited, above data are only for giving an example.
Generally speaking, the setting of Po value, need to by the emulation of network planning network optimization, get the optimized parameter of Po according to different scenes (compact district, open area etc.), gets the postiive gain of throughput.
The embodiment of the present invention provides a kind of Poewr control method, base station sends message by air interface to subscriber equipment, message comprises parameter preset, parameter preset is for determining the second transmitting power surplus of subscriber equipment, and then the power headroom reporting (PHR) of reception user equipment to report, power headroom reporting (PHR) comprises the second transmitting power surplus, base station is carried out power control according to the second transmitting power surplus to subscriber equipment, can disturb by coordinates user equipment room, promote cell throughout.

301, subscriber equipment receives the message that base station sends by air interface, and message comprises parameter preset.
Wherein, the base station is here the micro-station of Micro eNB, the UE in subscriber equipment Wei Weizhan community.
ENB can be by changing or increasing protocol fields, and to UE, send message by air interface, and this message comprises the parameter preset Po of eNB.Parameter preset Po is for limiting the transmitting power of UE.
302, subscriber equipment obtains the second transmitting power surplus according to the first transmitting power surplus of parameter preset and subscriber equipment.
Exemplary, when UE receives after the parameter preset Po that eNB issues, when reporting PHR to eNB, poor according to the first transmitting power surplus and parameter preset Po, be the difference that transmitting power surplus in PHR deducts Po, the PHR after being upgraded, the PHR after renewal comprises the second transmitting power surplus of UE, make UE when reporting PHR to eNB triggering, according to the transmitting power surplus in the PHR after upgrading, to eNB, report PHR.The second transmitting power surplus equals the poor of the first transmitting power surplus and parameter preset.If the first transmitting power surplus is less than parameter preset, the power headroom reporting (PHR) that subscriber equipment reports to base station comprises the first transmitting power surplus, and the second transmitting power surplus equals the first transmitting power surplus.
Wherein, when the first transmitting power surplus is subscriber equipment receipt message, the transmitting power surplus of subscriber equipment.
Transmitting power surplus is the poor of the maximum transmission power of UE and actual emission power, and the maximum transmission power of UE deducts the difference of actual emission power.
Wherein, UE can pass through at the actual emission power of PDSCH:
P PUSCH(i)=min{P CMAX,10log 10(M PUSCH(i))+P O_PUSCH(j)+α(j)·PL+△ TF(i)+f(i)}
Obtain.
Wherein, P pUSCH(i) be the actual emission power of UE; P cMAXmaximum transmission power for UE, configures by eNB; M pUSCH(i) be the transmission bandwidth of i sub-frame of uplink of PUSCH, with RB number, represent; P o_PUSCH(j) be the initial value of eNB when UE accesses for the first time; α (j) is path loss compensating factor, cell-level parameter, and totally 8 values, represent with 3bit, can be (0,0.4,0.5,0.6,0.7,0.8,0.9,1), the default value of configuration is 0.7 at present; PL is the downlink path loss in the assessment of UE side; △ tF(i) be adaptive encoding mode, f (i) is close-loop power control instruction, and i is subframe numbers.

304, subscriber equipment receives power control commands word from base station, and power command word is for controlling the transmitting power of subscriber equipment.
305, subscriber equipment is according to the whole actual emission power of the power control commands tone of Chinese characters.
Concrete, during the PHR of eNB after receiving renewal, because UE has upgraded the transmitting power surplus of UE, for eNB, amplified the actual emission power of UE, thereby eNB to carry out power control to UE falsely.Concrete, under the constant condition of the power spectral density of UE, eNB can obtain according to the PHR after upgrading the RB quantity that eNB is UE scheduling, then, eNB compares the eNB of this UE by the second parameter preset of the RB quantity of this UE and eNB, and upgrade according to comparative result the power control commands word f (i) that eNB sends to UE, so that UE upgrades the transmitting power of UE according to this power control commands word.Wherein, the second parameter preset is relevant with number of users and transmission bandwidth under this base station.
If RB quantity is less than goal-selling value, eNB sends power control commands word to UE, this power control commands word is used to indicate the actual emission power that UE reduces UE, like this, can to UE, carry out power control adjusting by the control of eNB, the transmitting power of the UE in restriction Wei Zhan community, reduces the transmitting power of the UE in Wei Zhan community, reduce UE in the Wei Zhan community interference to the UE in macro station community, to promote the throughput of whole community.
And when RB quantity is greater than the second parameter preset, eNB sends power control commands word to UE, this power control commands word is for the transmitting power of lifting UE.
Wherein, the initiation of the PHR of UE is on PUSCH, when UE meets PUSCH transmission condition, just to base station, sends PHR.The condition of initiating PHR can be divided into 3 kinds, and satisfied wherein any one condition can trigger and report.The one, prohibit timer overflows, and the path loss that path loss is caught up with while once sending PHR is compared the pathchange that its variable quantity is greater than RRC configuration, the 2nd, periodic timer overflows, the 3rd, UE receives RRC reallocation message, this message comprises phr config configuration, and UE need to comprise PHR when sending PUSCH for the first time.The condition here can, for other trigger condition, not limit here yet.Wherein, this PHR can account for 6 bit, can to base station, report once for 1s clock UE, also can, for setting At All Other Times, not limit here.
Like this, when eNB arranges the mode of order by eating dishes without rice or wine, and after the actual emission power of UE being controlled according to different Po values, the transmitting power of UE in Wei Zhan community is reduced, thereby micro-station is for macro station user's uplink interference reduction, coordinate the interference between user, promoted the throughput of whole community.Wherein, relation and the step 203 in the embodiment shown in Fig. 2 between Po value and cell throughout are similar, repeat no more here.
