Below in conjunction with accompanying drawing specific implementation of the present invention is further described in detail.
Can see that from background technology HSDPA is come modulation system, physical slot by time, code channel resource and the transport block size information of configuration UE use as a kind of high speed downlink grouping traffic by HS-SCCH by network side.Under the situation that modulation system is determined, physical slot by time that is disposed and code channel resource can determine the to eat dishes without rice or wine bearing capacity of physical layer reality; Calculate the physical carrier demand of transmission block according to the transmission block size that is disposed.Actual physical layer bearing capacity must satisfy the physical carrier demand of transmission block.
Under the TD-SCDMA system,, comprise the steps: by the flow process of HS-SCCH indicating modulation mode
After the CQI that step 11:NodeB reports according to the UE information such as the good transmission block size of Information Selection, modulating mode, code channel resource such as (Channel Quality Indication, channel quality indications), fill in HS-SCCH and send to UE;
After step 22:UE receives HS-SCCH, judge the modulation system that NodeB adopts by wherein code channel resource information and transport block size information.
In step 11, NodeB is for the UE that does not support 64QAM, and NodeB still adopts original modulating mode method for expressing, and the value that promptly disposes modulation system information is that 0 or 1 (0-QPSK, 1-16QAM) coming indicating modulation mode is QPSK or 16QAM.
In step 11, NodeB adopts the modulating mode method for expressing of describing among the present invention at the UE that supports 64QAM, keeping modulation system information is on the 1 bit size basis of invariable, by flexible configuration, makes this modulation system information can indicate QPSK/16QAM/64QAM.
Modulation system information in the HS-SCCH information (1 bit) still keeps, the implication of its definition 1 expression 16QAM remains unchanged, but 0 no longer only represents QPSK, 0 expression QPSK or 64QAM, concrete 0 is that expression QPSK or 64QAM are decided according to the physical layer actual bearer ability that calculates and the relation of physical carrier demand by UE.
Wherein, information such as the CQI that reports according to UE of NodeB and needs data quantity transmitted are selected transmission block size (TB SIZE), modulation system and employed HS-PDSCH code channel resource.
In step 22:
After the UE of support 64QAM received HS-SCCH, UE adopted the modulation system determination methods of describing among the present invention, was that deciding modulation system by simple differentiation is 16QAM, 64QAM or QPSK on the 1 bit size basis of invariable keeping modulation system information.
After supporting that the terminal of 64QAM receives High-Speed Shared Control Channel, read the modulation system information bit, if be 1, then with 16QAM as the terminal demodulation mode; If the modulation system information that reads is 0, then modulation system is QPSK or 64QAM, and terminal is calculated one of as follows and determined concrete modulation system:

Wherein the scope of coefficients R be (0,1].Coefficients R also can be determined by high level configuration or agreement agreement, and transmitting terminal Node B adopts identical R as judgment condition with receiving terminal UE.
When described terminal was calculated concrete modulation system with QPSK, the value of R was 0.9; When described terminal was calculated concrete modulation system with 64QAM, the R value was 0.3.
In step 22:
After not supporting that the UE of 64QAM receives HS-SCCH, still understand modulation system information according to original mode.That is: when the modulation system value of information was 0, what expression was used was the QPSK modulation system; When the value of modulation system information was 1, what expression was used was the 16QAM modulation system.
Be example with the Signalling exchange flow process at HSDPA service terminal and network side under the TD-SCDMA system more below, a kind of application example of technical scheme of the present invention is described.

Step 301:NodeB sends HS-SCCH to UE, relevant informations such as indication code channel resource, transmission block size and modulation system;
After step 302:UE receives HS-SCCH, calculate the modulation system that to use by transmission block information, code channel information and the modulation mode information of distributing.
Before step 301, terminal UE can be given Node B with reporting terminal capability information by existing reporting terminal capability information flow process and link establishment flow process, whether supports the information of 64QAM comprising terminal.Network side and end side all need to follow the ability constraints of correct transceive data, and promptly the definite code channel resource of NodeB can reach the requirement of carrying given transmission block size under the modulating mode of selecting.
In step 301, NodeB fills in code channel resource information, transmission block size and modulation system information in HS-SCCH when Resources allocation:
Wherein, if NodeB then fills in 1 according to the modulation system of current channel quality decision 16QAM in modulation system information; If 64QAM or QPSK are adopted in the NodeB judgement, then in modulation system information, fill in 0.
In step 302, after UE receives HS-SCCH information, the modulation system information bit that reads, if be 1, then with 16QAM as the terminal demodulation mode, if the modulation system information that reads is 0, then at first according to the QPSK modulation system, according to distributed time slot among the HS-SCCH, code channel resource information, calculate the actual bearer ability of the physical layer of eating dishes without rice or wine, according to the transmission block size of indicating among the HS-SCCH, calculate professional physical carrier demand according to the minimum punching limit 40% and coded system, if the physical layer actual bearer ability that calculates multiply by the physical carrier demand of coefficient 0.9 less than business, and the transmission rate that can carry of actual physics layer is less than the transmission rate of business, then with 64QAM as the terminal demodulation mode, otherwise with QPSK as the terminal demodulation mode.
The actual bearer ability of the physical layer of wherein eating dishes without rice or wine is meant, under given modulation system, in a high speed downlink shared channel HS-DSCH Transmission Time Interval, calculate the physical channel bit number that obtains with the physical resource of authorizing on the High-Speed Shared Control Channel, concrete: the bit number that can carry in the determined time slot format of each time slot mandate code channel number * authorization resources of physical channel bit number=mandate timeslot number *.
