Specific embodiment

The embodiment of the invention provides a kind of emission control method, user equipment and base stations.

In order to make the invention's purpose, features and advantages of the invention more obvious and easy to understand, below in conjunction with the present invention Attached drawing in embodiment, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described reality Applying example is only a part of the embodiment of the present invention, and not all embodiments.Based on the embodiments of the present invention, the common skill in this field Art personnel each other embodiments obtained without making creative work belong to the model that the present invention protects It encloses.

Below using UE as executing subject, a kind of emission control method provided in an embodiment of the present invention is described, please be join Read Fig. 1, the emission control method in the embodiment of the present invention, comprising:

101, determine the first transmission power of the process on current TTI, and the size of the first transmission power of process with should The size for the data packet for needing to send on the corresponding data channel of process is positively correlated；

Wherein, the process on each TTI safeguards there is mutually independent power control loop respectively, that is to say, that different TTI On corresponding first transmission power of process be to be controlled by different power control loops, those skilled in the art should Know, the control loop of transmission power can specifically integrate two kinds of control loops of inner-loop power control and external circule power control, here no longer in detail It describes in detail bright, first technology can be referred to.

In the embodiment of the present invention, user equipment determines of the process on current TTI by independent power control loop One transmission power, and make the number for needing to send on the size of the first transmission power of process data channel corresponding with the process It is positively correlated according to the size of packet, i.e., process needs the data packet that sends smaller, the transmitting function of the uplink DPCCH of the process determined Rate is smaller.

It should be noted that the process in the embodiment of the present invention refers to hybrid automatic repeat-request (HARQ, Hybrid Automatic Repeat Request) process.When using concurrent HARQ process, hair that multiple HARQ processes can be concurrent Send data.

Since in HSUPA system, the absolute grant value (AG, Absolute Grant) of different processes is different, AG is big Process, the data packet usually sent is also big, for being limited to only send the process of non-scheduled data, then the process send data Packet is smaller, correspondingly, the AG of the process is also smaller, in addition, there is likely to be certain processes to be deactivated (i.e. de-active). Therefore, in a kind of realization example, the first transmission power of the process is determined according to the AG of the process on current TTI, and is made The size of first transmission power of process needs the data packet sent to be positively correlated with the process.Optionally, according to each process The difference of AG determine the SINR target value on each process-time so that UE uses different first in different process-times Transmission power.

Enhancement information designated lane (E-DCH, Enhanced Dedicated Channel) supports 2 milliseconds of TTI, E-DCH Transformat combination instruction (E-TFCI, E-DCH Transport Format Combination Indicator) is used to indicate The transformat combination of E-DCH corresponds between the value and transformat combination of E-TFCI.It is realized in example in another kind, if working as The E-TFCI value of process on preceding TTI is greater than default first threshold value, then UE is true according to the E-TFCI value of the process on current TTI First transmission power of the fixed process, since E-TFCI value can show that enhancement information designated lane Dedicated Physical Data Channel The data block size of (E-DPDCH, E-DCH Dedicated Physical Data Channel) current transmission, therefore, for The E-TFCI value of process determines the first transmission power of the process, enables to when the data packet that process needs to send is smaller, First transmission power of the corresponding process is also smaller.

It should be noted that the main thought of the embodiment of the present invention is on different TTI by independent power control loop Road determines the first transmission power of the process on corresponding TTI, makes it possible to be independently arranged the process for the process on each TTI The first transmission power.In above two implementation, AG the and E-TFCI value for being based respectively on process is implemented, in other realizations In mode, it can also implement inwardly in the present invention, the other parameters based on process are embodied, and are not limited herein It is fixed.

102, in the TTI, according to the first determining transmission power, pilot tone letter is emitted in the corresponding control channel of the process Breath, so that the receiving end (such as base station) of above-mentioned data packet carries out channel estimation using above-mentioned pilot frequency information, and according to channel estimation Result above-mentioned data channel is demodulated；

It should be noted that the technical solution in the present embodiment can be applied in HSUPA, it is single when being introduced in HSUPA A mixed automatic retransmission mechanism (HARQ, Hybrid Automatic Repeat Request) namely when per HARQ, due to In HARQ process, corresponding data channel (such as Dedicated Physical Data Channel (DPDCH, DPDCH Dedicated Physical Data CHannel)) there are problems that size data packet scheduling, it needs (such as dedicated to the corresponding control channel of the data channel Physical control channel (DPCCH, Dedicated Physical Control Channel)) transmission power controlled, answer When knowing, it may also be possible to apply the invention for other access technologies there are similar problems.

After the first transmission power that step 101 determines the process on current TTI, UE can be according to the first of the process the hair Power is penetrated, according to the first determining transmission power on current TTI, pilot tone letter is sent in the corresponding control channel of the process Breath so that base station carries out channel estimation using the pilot frequency information, and demodulates data channel according to the result of channel estimation, It should be noted that controlling in HSUPA the first transmission power of DPCCH, in addition to being carried out convenient for base station to DPDCH Other than demodulation, DPCCH has also been comprehensively considered to other channel effects in HSUPA, such as E-DPCCH etc..

It is executing subject to the present invention using UE below by taking the AG according to process determines the first transmission power of the process as an example Emission control method in embodiment is described, referring to Fig. 2, the emission control method in the embodiment of the present invention, comprising:

201, UE obtains the AG of the process on the current TTI that network side issues；

In the embodiment of the present invention, the serving BS that AG is UE distributes to the E-DPDCH transmission power of the UE and DPCCH emits The maximum ratio of power, UE equivalent can know the maximum transmission data rate that currently can be used by AG.

In general, network side (such as base station) passes through Enhanced-DedicatedChannel absolute grant channel (E- when to some process scheduling AGCH, E-DCH Absolute Grant Channel) AG of the process is issued to UE, UE receives the process by E-AGCH AG；Alternatively, UE can also obtain the AG of process otherwise, for example, third generation cooperative partner program (3GPP, 3rd Generation Partnership Project) in define AG table, which is used to indicate the index value of different authorizations, All maintenance has AG table on base station and on UE, and the process of authorization is as follows: base station obtains this according to the warrant quantity of process inquiry AG table and awards Then the index value of the authorization is transferred to UE by the index value of power, UE inquires AG table according to the index value, to obtain the process Absolute grant value, certainly, in embodiments of the present invention, UE can also obtain the AG of process otherwise, not make herein It limits.

By taking HSUPA system as an example, in HSUPA system, uplink scheduling is divided into scheduling (i.e. all based on full HARQ process HARQ scheduling) and scheduling (i.e. per HARQ scheduling) based on single HARQ process, HSUPA uplink using synchronous HARQ mechanism, Therefore the transmission and merging decoding of HARQ is all as unit of HARQ process, wherein all HARQ, which are dispatched with all HARQ processes, is Unit is scheduled, and per HARQ scheduling is scheduled as unit of each HARQ process.In the embodiment of the present invention, work as unlatching When per HARQ is dispatched, UE obtains the AG of each process, and safeguards respective service allowable value (i.e. for each process Serving Grant value).

202, UE determines the first transmission power of above-mentioned process according to the AG of above-mentioned process；

In a kind of application scenarios, base station or radio network controller issue reflecting for AG and AG-SINR target value to UE Relationship is penetrated, when UE gets process AG in step 201, according to the mapping relations of above-mentioned AG and AG-SINR target value, is determined And difference of the corresponding first SINR target value of the AG of above-mentioned process relative to the 2nd SINR target value corresponding with reference AG, In, the above-mentioned reference transmission power for corresponding to control channel with reference to AG；UE by the reference transmission power of above-mentioned control channel with it is upper State the first transmission power that the sum of difference is determined as above-mentioned process.
