Description

A kind of up launching technique and subscriber equipment

Technical field

The present invention relates to communication technical field, particularly relate to a kind of up launching technique and subscriber equipment.Background technology

Up-high speed Packet Service access technology (High Speed Uplink Packet Access, HSUPA) technology is a kind of high-speed uplink packet access technology based on Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division MultipleAccess, WCDMA) technology.

In high speed uplink data communication, data channel needs certain Signal Interference and Noise Ratio (Signal to Interference plus Noise Ratio, SINR), to ensure the transmission of the data service of corresponding data rate, secondly, the data block can supported along with HSUPA is increasing, and the reception SINR required by pilot channel of this data block of network side demodulation also can increase thereupon.Wherein, channel estimating can be obtained by pilot channel.In the prior art, Dedicated Physical Control Channel (E-DCH Dedicated Physical Data Control Channel, DPCCH) is generally used for transmitting pilot tone, and E-DPCCH strengthens the control information of Dedicated Physical Data Channel (E-DPDCH) for carrying.

In prior art, when data block is larger, can can be strengthened the scheme of power as auxiliary enhancing pilot tone of Dedicated Physical Control Channel (E-DCH Dedicated Physical Control Channel, E-DPCCH) by increasing (Boost) by enhancing.E-DPCCH strengthens the control information of Dedicated Physical Data Channel for carrying.Dedicated Physical Control Channel (E-DCH DedicatedPhysical Data Control Channel, DPCCH) is generally used for transmitting pilot tone.When the size of data block, i.e. transformat joint instructions (Transport Format CombinationIndicator, E-TFCI), when E-TFCI is greater than E-DPCCH Boost threshold value, E-DPCCH is carried out the network side demodulation of channel estimating for data E-DPDCH as Auxiliary Pilot Channel again by network side on the basis of correct network side demodulation E-DPCCH.Namely, combined by E-DPCCH and DPCCH as new pilot channel transmission data, wherein, the Boost power of E-DPCCH is then for required total pilot power of network side demodulating data deducts the dump power value of the transmitting power of DPCCH.That is, for general subscriber equipment, total transmitting power of multiple signal channel launched can not be too high, otherwise total transmitting power will exceed the restriction of up gross power.

But; in the Boost scheme of E-DPCCH; also HS-DPCCH(High-Speed Dedicated Physical Control Channel may be there is in uplink) feedback; HS-DPCCH is typically used in transmission HS-DPSCH(high-speed dedicated physical shared channel; be generally used for the transmission of downlink data) feedback data, as ACK/NACK(ack/nack) feedback.Then can there is the ascending power consumption corresponding to HS-DPCCH, total transmitting power of E-DPDCH, DPCCH, E-DPCCH and HS-DPCCH may be caused to exceed the restriction of up gross power.Meanwhile, for identical upstream data rate, consume more power and mean lower efficiency of transmission, the lifting of up-link total throughout can be limited.For how under the constant prerequisite of the total emitted energy of inhibit signal, the uplink transmission power of reasonable disposition E-DPCCH is so that the emission effciency of distributing between multiple channel just becomes a problem.
