Description
Technical field
The present invention relates to the communications field, and more specifically, relate to the method and subscriber equipment of distributing power.
Background technology
CPC (Continuous Packet Connectivity, continuous bag access connects) and DC-HSUPA (Dual carrier High Speed Uplink Packet Access, the access of two carrier wave high speed uplink packet) two kinds of characteristics play very important effect on WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) Road of Evolution.CPC characteristic alleviates the up overall load of network by the up transmitting time reducing UE (User Equipment, subscriber equipment), thus supports the uplink service of more users; The object of DC-HSUPA characteristic is to promote the up gain of UE under good signal, obtaining higher up digit rate.
DC-HSUPA transmits the higher up digit rate of acquisition by line number on carrying out on two carrier waves simultaneously.UE carries out independent E-TFC (enhanced Transport Format Combination Indicator on each carrier, the transformat combination strengthened) select and coding, be then multiplexed on a transmitter and launch, power on two carrier waves is superposition relative to same transmitter, final transmitting power can not exceed the maximum transmission power of this transmitter, so the power of necessary coordinated allocation two carrier waves.
CPC characteristic is the scene for UE discontinuous number, allows UE close transmitter, and only sends in the moment of agreement.Grow out of nothing at every turn launch time, because transmitter is cut out before, need to open transmitter transmission DPCCH (Dedicated Physical Control Channel, Dedicated Physical Control Channel) in advance leading, allow network ensure the performance of uplink channel estimation.Such as, if data will be sent at the 8th TTI (Transmission Time Interval, Transmission Time Interval), then need 4 TTI in advance, namely send DPCCH at the 4th TTI leading, therefore need to carry out E-TFC selection at the 3rd TTI.
When DC-HSUPA and CPC characteristic is concurrent, two carrier waves support discontinuous transmission simultaneously, and the pattern of discontinuous transmission can be different.Therefore, there will be following scene:
Carrier wave 1 will send HSUPA bag at the 10th TTI, and carrier wave 2 will send HSUPA bag at the 8th TTI;
At the 3rd TTI, carry out E-TFC selection in advance on carrier 2, finding that there is data needs to send, then send DPCCH immediately leading;
At the 5th TTI, carry out E-TFC selection in advance on carrier 1, finding that there is data needs to send, then send DPCCH immediately leading;
At the 8th TTI and the 10th TTI, carrier wave 2 and carrier wave 1 carry out the transmission of HSUPA bag respectively.
According to Current protocol, at the 3rd TTI, for carrier wave 2 select E-TFC time, because carrier wave 1 does not send HSUPA bag, so carrier wave 2 can exclusively enjoy remaining transmitting power.At the 5th TTI, for carrier wave 1 select E-TFC time, because carrier wave 2 does not retransmit HSUPA bag not in transmission yet, then think and can exclusively enjoy remaining transmitting power.At the 8th TTI, carrier wave 2 sends HSUPA bag, needs to retransmit this HSUPA wrap at the 9th and the 10th TTI, but at the 10th TTI, carrier wave 1 also will send HSUPA bag, and at this moment the power of two carrier waves can clash, and causes the HSUPA of a carrier wave or two carrier waves to wrap and does not send out not go out simultaneously.

Fig. 1 shows the indicative flowchart of the method 100 of the distribution power according to the embodiment of the present invention.The method 100 can be performed by subscriber equipment.As shown in Figure 1, the method 100 comprises:
S110, the moment is selected at the transformat combination E-TFC of the enhancing of first carrier, obtain the first power occupied information, this the first power occupied information indicates the second carrier wave to choose corresponding data from the E-TFC of this second carrier wave and sends the power successfully always taken, the E-TFC of this second carrier wave is engraved in more than the first two moment of corresponding data delivery time when selecting, and this second carrier wave and this first carrier are multiplexed on same transmitter;
S120, according to this first power occupied information, this first carrier carries out E-TFC selection.
In DC-HSUPA scene, subscriber equipment is carried previous TTI and carry out E-TFC selection on two carrier wave, is two allocation of carriers power.CPC characteristic needs subscriber equipment when growing out of nothing transmission data at every turn, and multiple TTI (two more than TTI) carries out E-TFC selection in advance.Multi-carrier HSUPA and CPC concurrent time, each carrier wave all can occur that in advance multiple TTI selects the situation of E-TFC.A kind of scene such as shown in Fig. 2, carrier wave 1 and carrier wave 2 all need 5 TTI in advance to select E-TFC.
In embodiments of the present invention, first power occupied information indicates the second carrier wave to choose corresponding data from the E-TFC of the second carrier wave and sends the power successfully always taken, wherein, the E-TFC of the second carrier wave is engraved in more than the first two moment of corresponding data delivery time when selecting, and the second carrier wave and first carrier are multiplexed on same transmitter.
In embodiments of the present invention, first carrier is the carrier wave that will carry out E-TFC selection; Second carrier wave is be multiplexed on same transmitter with first carrier, is engraved in the carrier wave in more than the first two moment of corresponding data delivery time when E-TFC selects.Such as, in the scene shown in Fig. 2, concerning carrier wave 1, carrier wave 2 is for be multiplexed on same transmitter with carrier wave 1, the carrier wave in 5 moment before being engraved in corresponding data delivery time during E-TFC selection, therefore, when selecting E-TFC for carrier wave 1, carrier wave 1 is first carrier, and carrier wave 2 is the second carrier wave.In the scene of multicarrier, the second carrier wave may have multiple, at this moment needs to consider the second all carrier waves.
When second carrier wave completes E-TFC selection before first carrier, due to the second carrier wave in advance the E-TFC that carries out of multiple moment select, therefore, in order to avoid the power conflict of intercarrier, need consideration second carrier wave to choose corresponding data from E-TFC and send the situation taking power in successful whole period.Specifically, because the second carrier wave just started to send data after the several moment after E-TFC has selected, so, after the E-TFC of the second carrier wave has selected, even if ensuing carrier wave of several moment second does not send data, in order to avoid conflict, also think that the second carrier occupancy power.That is, before sending data from E-TFC chooses, but for taking the situation not using power, and when sending data, for taking and using the situation of power.Therefore, in embodiments of the present invention, subscriber equipment selects the moment at the E-TFC of first carrier, first obtain instruction second carrier wave and choose from the E-TFC of the second carrier wave the first power occupied information that corresponding data send the power successfully always taken, and then according to the first power occupied information, first carrier carries out E-TFC selection.Owing to considering the power that the second carrier wave takies when carrying out E-TFC selection on first carrier always, therefore, when first carrier and the second carrier wave send data simultaneously, the power of intercarrier also can not clash.
Therefore, the method of the distribution power of the embodiment of the present invention, other carrier wave carrying out E-TFC selection according to indicating multiple moment in advance chooses from E-TFC the information that corresponding data send the power successfully always taken, carry out E-TFC selection, the transmitting power of multicarrier can be avoided to produce conflict, the data on multicarrier can normally be sent.
Should be understood that the embodiment of the present invention not only may be used for the concurrent scene of multicarrier HSPUA and CPC, the scene being engraved in the subcarrier multiplexing in more than the first two moment of corresponding data delivery time when various E-TFC selects can also be used for.For convenience, the embodiment of the present invention is only described for the scene that multicarrier HSPUA and CPC is concurrent, but the embodiment of the present invention is not limited to this.
Should also be understood that in embodiments of the present invention, the moment can be TTI, but the embodiment of the present invention is not limited to this, and such as, the moment can also be that other represents the chronomere of commitment defini interval.
In embodiments of the present invention, as shown in Figure 3, alternatively, the method 100 of distributing power also comprises:
S130, according to the E-TFC selection result of this second carrier wave, records this first power occupied information;
S140, when determining to select corresponding data to send successfully to the E-TFC of this second carrier wave, upgrades this first power occupied information.
After the E-TFC of the second carrier wave has selected, subscriber equipment can according to the E-TFC selection result of the second carrier wave, record the first power occupied information, represent that the second carrier wave can take power until corresponding data send successfully after E-TFC selects always, to select the moment to carry out E-TFC selection according to the first power occupied information at the E-TFC of first carrier.Alternatively, subscriber equipment can record the watt level of the second carrier occupancy, the moment that the watt level and starting that also can record the second carrier occupancy takies, and the concrete mode of the embodiment of the present invention to record first power occupied information does not limit.
Send successfully in corresponding data, the second carrier wave no longer takies power, and therefore subscriber equipment when determining to select corresponding data to send successfully to the E-TFC of the second carrier wave, can upgrade the first power occupied information.Alternatively, the power of the second carrier occupancy can reset by subscriber equipment, also can delete the first power occupied information, that is, represent that the second carrier wave no longer takies power, and the concrete mode of the embodiment of the present invention to renewal first power occupied information does not limit.
Like this, select the moment at the E-TFC of first carrier, subscriber equipment can obtain the first power occupied information, and according to the first power occupied information, first carrier carries out E-TFC selection.
Therefore, the method for the distribution power of the embodiment of the present invention, by recording and upgrading power occupied information, and carries out E-TFC selection according to power occupied information, the transmitting power of multicarrier can be avoided to produce conflict, the data on multicarrier can normally be sent.
In embodiments of the present invention, as shown in Figure 4, alternatively, S120 comprises:
S121, according to this first power occupied information, determine this first carrier can dump power;
S122, according to this first carrier can dump power, this first carrier carries out E-TFC selection.
In S121, subscriber equipment according to the first power occupied information, determine first carrier can dump power.Subscriber equipment first carrier E-TFC select the moment, according to the first power occupied information, determine the power of the second carrier occupancy, so determine first carrier can dump power.Alternatively, S121 comprises:
According to the first power occupied information, determine to select the subsequent time in moment at the E-TFC of first carrier, but the second carrier wave takies and does not use or taken and the power used;
But determine first carrier can dump power be that the dump power of transmitter deducts the second carrier wave and taken and do not use or taken and the power used.
Specifically, when E-TFC selected by subscriber equipment on first carrier, need the power determining subsequent time to take situation, subscriber equipment need according to the power of this subsequent time take situation determination first carrier can dump power.In embodiments of the present invention, subscriber equipment, according to the first power occupied information, determines the power that the second carrier wave has taken.Because the E-TFC of the second carrier wave is engraved in more than the first two moment of corresponding data delivery time when selecting, therefore, second carrier occupancy power has two kinds of situations: on the one hand, and the second carrier wave has taken power at this subsequent time but do not sent data, but has namely taken and do not use power; On the other hand, the second carrier wave sends data at this subsequent time, has namely taken and has used power.Subscriber equipment, according to the first power occupied information, is determined at this subsequent time, but the second carrier wave has taken and do not use or taken and the power used.Determine first carrier can dump power time, this part power be deducted, but namely determine first carrier can dump power be that the dump power of transmitter deducts the second carrier wave and taken and do not use or taken and the power used.Should be understood that in embodiments of the present invention, the dump power of transmitter is the power that transmitter can be used in E-TFC selection, and such as, transmitter maximum transmission power deducts control channel power.
In S122, subscriber equipment according to first carrier can dump power, first carrier carries out E-TFC selection.Determine first carrier can dump power after, subscriber equipment based on first carrier can dump power on first carrier, select E-TFC.Such as, subscriber equipment according to first carrier can dump power, authorization power and data volume to be passed on first carrier, carry out E-TFC selection.
Therefore, the method of the distribution power of the embodiment of the present invention, the information of the power that other carrier wave carrying out E-TFC selection according to indicating multiple moment in advance takies always, determine carrier wave can dump power, and then carry out E-TFC selection, the transmitting power of multicarrier can be avoided to produce conflict, the data on multicarrier can normally be sent.
In embodiments of the present invention, as shown in Figure 5, alternatively, the method 100 of distributing power also comprises:
S150, the moment is selected at the E-TFC of this first carrier, obtain the second power occupied information, this the second power occupied information instruction the 3rd carrier wave is chosen corresponding data from the E-TFC of the 3rd carrier wave and is sent the power successfully always taken, the E-TFC of the 3rd carrier wave is engraved in the previous moment of corresponding data delivery time when selecting, the 3rd carrier wave and this first carrier are multiplexed on same transmitter;
S120 also comprises:
S123, according to this first power occupied information and this second power occupied information, this first carrier carries out E-TFC selection.
In embodiments of the present invention, second power occupied information instruction the 3rd carrier wave is chosen corresponding data from the E-TFC of the 3rd carrier wave and is sent the power successfully always taken, wherein, the E-TFC of the 3rd carrier wave is engraved in the previous moment of corresponding data delivery time when selecting, the 3rd carrier wave and first carrier are multiplexed on same transmitter.
In embodiments of the present invention, the 3rd carrier wave is be multiplexed on same transmitter with first carrier, is engraved in the carrier wave in the previous moment of corresponding data delivery time when E-TFC selects.Such as, multi-carrier HSUPA and CPC concurrent time, a carrier wave sends successfully after HSUPA bag, newly send another HSUPA when wrapping, only need carry previous TTI carries out E-TFC selection, and in this case, this carrier wave is exactly the 3rd carrier wave.In the scene of multicarrier, the 3rd carrier wave may have multiple, at this moment needs to consider the 3rd all carrier waves.
When 3rd carrier wave selects E-TFC before first carrier, the E-TFC of first carrier selects the power also will considering the 3rd carrier occupancy.Therefore, in embodiments of the present invention, subscriber equipment selects the moment at the E-TFC of first carrier, and also will obtain the second power occupied information, then subscriber equipment is according to the first power occupied information and the second power occupied information, and first carrier carries out E-TFC selection.Owing to carrying out considering when E-TFC selects the power that the second carrier wave and the 3rd carrier wave take on first carrier always, therefore, when they send data simultaneously, the power of intercarrier also can not clash.
In embodiments of the present invention, alternatively, S123 comprises:
According to the first power occupied information and the second power occupied information, determine first carrier can dump power;
According to first carrier can dump power, first carrier carries out E-TFC selection.
Subscriber equipment first carrier E-TFC select the moment, respectively according to the first power occupied information and the second power occupied information, determine the power of the second carrier wave and the 3rd carrier occupancy, so determine first carrier can dump power.Alternatively, this process comprises:
According to the first power occupied information, determine to select the subsequent time in moment at the E-TFC of first carrier, but the second carrier wave takies and does not use or taken and the power used;
According to the second power occupied information, determine the subsequent time in the E-TFC selection moment at first carrier, the 3rd carrier wave has taken and the power used;
But determine first carrier can dump power be that the dump power of transmitter deducts the 3rd carrier wave and to have taken and the power used and the second carrier wave have taken and do not use or taken and the power used.
Specifically, when E-TFC selected by subscriber equipment on first carrier, according to the power of subsequent time take situation determination first carrier can dump power.The E-TFC of the second carrier wave is engraved in more than corresponding data delivery time the first two moment when selecting, and therefore, the second carrier wave, at this subsequent time, may take power but not send data, also may send data.And the E-TFC of the 3rd carrier wave is engraved in previous moment of corresponding data delivery time when selecting, therefore the 3rd carrier wave may use power at this subsequent time.Therefore, subscriber equipment, according to the first power occupied information, is determined at this subsequent time, but the second carrier wave has taken and do not use or taken and the power used; According to the second power occupied information, determine at this subsequent time, the 3rd carrier wave has taken and the power used.Determine first carrier can dump power time, deduct these power, but namely determine first carrier can dump power be that the dump power of transmitter deducts the 3rd carrier wave and to have taken and the power used and the second carrier wave have taken and do not use or taken and the power used.
Determine first carrier can dump power after, subscriber equipment based on first carrier can dump power on first carrier, select E-TFC.
Therefore, the method for the distribution power of the embodiment of the present invention, according to the information of the power that other carrier wave of instruction takies always, determine carrier wave can dump power, and then carry out E-TFC selection, the transmitting power of multicarrier can be avoided to produce conflict, the data on multicarrier can normally be sent.
Should understand, in various embodiments of the present invention, the size of the sequence number of above-mentioned each process does not also mean that the priority of execution sequence, and the execution sequence of each process should be determined with its function and internal logic, and should not form any restriction to the implementation process of the embodiment of the present invention.
Below in conjunction with Fig. 6 A to 6D, for four concrete scenes, the method for the distribution power of the embodiment of the present invention is described in further detail.It should be noted that these examples are only used to help skilled in the art to understand possible execution modes more of the present invention, but not all execution modes enumerated exhaustively, thus can not be interpreted as limitation of the scope of the invention.
When DC-HSUPA and CPC is concurrent, two carrier waves support discontinuous transmission simultaneously, and each carrier wave grows out of nothing when sending data, all need to carry out E-TFC selection in advance and to send DPCCH leading.As shown in Figure 6A, carrier wave 2 needs the transmission carrying out HSUPA bag at the 8th TTI, and carrier wave 1 needs the transmission carrying out HSUPA bag at the 10th TTI, and therefore, UE will be that carrier wave 2 selects E-TFC at the 3rd TTI, is that carrier wave 1 selects E-TFC at the 5th TTI.In such a scenario:
At the 3rd TTI, carrier wave 2 needs to carry out E-TFC selection.UE takies situation according to the power of the 4th TTI and distributes power, determine there is no other carrier occupancy power at the 4th TTI, determine thus carrier wave 2 can dump power be the dump power of transmitter, according to carrier wave 2 can dump power be that carrier wave 2 selects E-TFC, and record the first power occupied information.Such as, the power P that carrier wave 2 takies is recorded
2a.
At the 5th TTI, carrier wave 1 needs to carry out E-TFC selection.UE obtains the first power occupied information, according to the power P that the first power occupied information determination carrier wave 2 takies
2a(because carrier wave 2 does not send data at the 6th TTI, therefore, at the 6th TTI, P
2afor taking but untapped power), determine thus carrier wave 1 can dump power be the power P that the dump power of transmitter deducts carrier wave 2 and takies
2a, then according to carrier wave 1 can dump power be that carrier wave 1 selects E-TFC.
At the 8th TTI, carrier wave 2 carries out the transmission of HSUPA bag, retransmits at the 9th, 10 TTI.
At the 10th TTI, carrier wave 1 carries out the transmission of HSUPA bag.Owing to considering the power that carrier wave 2 takies when carrying out E-TFC selection before, therefore the power of carrier wave 1 can not produce with the power of carrier wave 2 and conflict, and the HSUPA bag on two carrier waves can normally send.
Fig. 6 B is the concurrent another kind of scene of DC-HSUPA and CPC.In such a scenario, carrier wave 2 needs the transmission carrying out HSUPA bag at the 7th TTI, and carrier wave 1 needs the transmission carrying out HSUPA bag at the 11st TTI, and therefore, UE will be that carrier wave 2 selects E-TFC at the 2nd TTI, is that carrier wave 1 selects E-TFC at the 6th TTI.
At the 2nd TTI, carrier wave 2 needs to carry out E-TFC selection.UE takies situation according to the power of the 3rd TTI and distributes power, determine there is no other carrier occupancy power at the 3rd TTI, determine thus carrier wave 2 can dump power be the dump power of transmitter, according to carrier wave 2 can dump power be that carrier wave 2 selects E-TFC, and record the first power occupied information.Such as, the power P that carrier wave 2 takies is recorded
2b.
At the 6th TTI, carrier wave 1 needs to carry out E-TFC selection.UE obtains the first power occupied information, according to the power P that the first power occupied information determination carrier wave 2 takies
2b(because carrier wave 2 will send data at the 7th TTI, therefore, at the 7th TTI, P
2bfor taking and the power used), determine thus carrier wave 1 can dump power be the power P that the dump power of transmitter deducts carrier wave 2 and takies
2b, then according to carrier wave 1 can dump power be that carrier wave 1 selects E-TFC.
At the 7th TTI, carrier wave 2 carries out the transmission of HSUPA bag, retransmits at the 8 to 11 TTI.
At the 11st TTI, carrier wave 1 carries out the transmission of HSUPA bag, and owing to considering the power that carrier wave 2 takies when carrying out E-TFC selection before, therefore the power of carrier wave 1 can not produce with the power of carrier wave 2 and conflict, and the HSUPA bag on two carrier waves can normally send.
Fig. 6 C is concurrent another scene of DC-HSUPA and CPC.In such a scenario:
Be that carrier wave 2 selects E-TFC at the 1st TTI, UE, and record the power P that carrier wave 2 takies
2c.At the 6th TTI, carrier wave 2 sends HSUPA and is bundled into merit, and UE upgrades the power that carrier wave 2 takies, and is reset.
At the 7th TTI, carrier wave 1 needs to carry out E-TFC selection.UE obtains the power that carrier wave 2 takies, because the power that carrier wave 2 takies resets, namely, the power do not taken, therefore, UE determine carrier wave 1 can dump power be the dump power of transmitter, according to carrier wave 1 can dump power be that carrier wave 1 selects E-TFC, and record the power P that carrier wave 1 takies
1c.
Carrier wave 2 needs the new HSUPA of transmission to wrap at the 9th TTI, and therefore at the 8th TTI, carrier wave 2 needs to carry out E-TFC selection.UE obtains the power P that carrier wave 1 takies
