The present invention relates to mobile communication technology, be particularly related to a kind of with reference to E-TFCI (E-DCH TransportFormat Combination Indicator, the indication of enhancing dedicated transmission channel transformat combination) method, channel configuration module and the subscriber equipment of configuring E-DCH (Enhanced Dedicated Channel strengthens dedicated transmission channel) channel.

Background technology

The operable TFS Transport Format Set one of E-DCH channel has four kinds, every kind of set comprises multiple transformat, agreement TS25.321 Annex B (normative): provided the corresponding transmission block bit number (TB Size) of each transformat j (TB Index) in four kinds of set and the set among the E-DCH Transport Block Size Tables forFDD, example is as shown in table 1.

Table 1.

Network is specified when setting up an E-DCH channel and is used wherein a kind of set, and a kind of transformat that the E-DCH channel is chosen in the set when each TTI sends data sends to network side.

UE (User Equipment, subscriber equipment) when realizing that data send, need be data map in the E-DCH channel to physical channel E-DPDCH (E-DCH Dedicated Physical Data Channel, strengthen the dedicated transmission channel Dedicated Physical Data Channel) on, physical channel passes through spread spectrum, scramblings etc. send to network side by radio system after handling.

Current HSUPA (High Speed-Uplink Packet Access, the high speed uplink packet access) in the system, UE is when realizing the E-DPDCH channel spread, need the content that is provided with reference to (Reference) E-TFCI, this is provided with content and is carried in the relevant configuration message that network side is handed down to UE, and this relevant setting option that content is set is included in the following table 2:

5, make N _{E, data, j}Equal corresponding E-DPDCH number among the SET2 and be 1 minimum N _{E, data}, that is, and preferential select punching limiting value punching that spread spectrum data that each TTI of UE is sent can dispose according to high level after, the E-DPDCH number is can satisfy the minimum N that transmittability requires at 1 o'clock _{E, data}

If determine L according to above-mentioned steps _{E, ref}Or L _{E, j}, then calculate and finish; Otherwise continue step 6.

If 6 S set ET2 are empty, after promptly the punching limiting value that can dispose according to high level was punched, still the transmittability that can't satisfy the demand then directly made N _{E, data, j}Equal to satisfy N among the SET0 _{E, data}-PL _Max* N _{E, j}The N of＞=0 maximum _{E, data}

Wherein, PL _MaxExpression is by the punching limiting value of UE ability decision, except UE supports and network side support N _{E, data}=2 * N ₂+ 2 * N ₄User's value be outside 0.33, under other situations, this value is 0.44.

That is the punching limiting value PL that determines according to the UE ability again, _Max, from SET0, select to satisfy the maximum N that punching back transmittability requires _{E, data}

In sum, if minimum CCTrCH bit number that exists among the described SET0 and E-DPDCH channel number that should minimum CCTrCH bit number correspondence are 1, make then that described the 2nd E-DPDCH channel number is that finish 1 back; Otherwise:

According to the maximum punching limiting value of network side configuration data volume (K to respective transmissions _{E, ref}Or K _{E, j}) punch handle after, having the CCTrCH bit number and the corresponding E-DPDCH channel number that can satisfy transmittability among the described SET0 is 1, then makes L _{E, ref}Or L _{E, j}Be 1,, then make L if having the CCTrCH bit number to satisfy transmittability but corresponding E-DPDCH channel number is not 1 all _{E, ref}Or L _{E, j}Finish behind the E-DPDCH channel number for maximum CCTrCH bit number correspondence wherein; Otherwise:

According to the punching limit of UE capability decision data volume (K to respective transmissions _{E, ref}Or K _{E, j}) punch handle after, inquire about the maximum CCTrCH bit number that can satisfy transmittability among the described SET0, and make L _{E, ref}Or L _{E, j}E-DPDCH channel number for this maximum CCTrCH bit number correspondence.

Illustrate with concrete example:

Scene 1: suppose that it is (N that each TTI needs data quantity transmitted ₃₂+ 1) SET1={N that, then satisfies condition ₁₆, N ₈, N ₄, 2 * N ₄, 2 * N ₂, 2 * N ₂+ 2 * N ₄; So, finally select N _{E, data, j}=N ₁₆

Scene 2: need supposing data quantity transmitted is (1.25* (2 * N ₄)), PL _Non-maxBe 0.8, then according to above-mentioned process, the SET1={2 * N that satisfies condition ₂, 2 * N ₂+ 2 * N ₄, and because the number of the E-DPDCH of the minimum value correspondence of SET1 is 2, so the condition of step 3 can't satisfy, the process that execution in step 4 is later obtains SET2={2 * N ₄, 2 * N ₂, 2 * N ₂+ 2 * N ₄, then according to above-mentioned process, N as can be known _{E, data, j}=2 * N ₄

Scene 3: need supposing data quantity transmitted is 0.8* (2 * N ₂+ 2 * N ₄), configuration PL _Non-maxBe 0.9, then, SET1={2 * N ₂+ 2 * N ₄; And the SET2=empty set; So N that finally obtains _{E, data, j}=2 * N ₂+ 2 * N ₄

By said process as can be known, influence L _{E, j}Or L _{E, ref}Factor mainly contain the PL of configuration _Non-maxThe punching limit, by the PL of UE and network side decision _MaxThe punching limit and the bit number that needs transmission.
