The network appoints to use one of the sets when establishing an E-DCH channel, and the E-DCH channel selects one transmission format in the set to send to the network side when sending data in each TTI.
When a UE (User Equipment) implements Data transmission, data in an E-DCH Channel needs to be mapped onto a Physical Channel E-DPDCH (enhanced Dedicated Physical Data Channel), and the Physical Channel is transmitted to a network side through a radio frequency system after being processed by spreading and scrambling.
In a current HSUPA (High Speed-Uplink Packet Access) system, when a UE implements E-DPDCH channel spreading, a set content of an E-TFCI needs to be referred to (Reference), where the set content is carried in a related configuration message sent to the UE by a network side, and related setting items of the set content are included in the following table 2:
TABLE 2 reference E-TFCI configuration content
| IE/Group Name (cell/group name) | Presence (Presence) | Range (scope) | IE Type and Reference (cell type and scope) |
| Reference E-TFCI Information (reference E-TFCI information set) | 1..<maxnoofRefETFCIs> (reference E-TFCI information set in common With maxnoofferfcis group) | ||
| ＞Reference E-TFCI | M (must choose) | INTEGER(0..127) (integer of 0 to 127) | |
| ＞Reference E-TFCI Power Offset (reference power bias) | M (must choose) | INTEGER(0..29) (integer of 0 to 29) |
Wherein, the reference E-TFCI corresponds to one TB Index in the table 1, the value range is 0 to 127, the tables similar to the table 1 have 3, and the lengths of different tables are possibly different due to inconsistency of definition modes. The Reference Power Offset (Reference E-TFCI Power Offset) is a Power Offset value which is expected to be set, the value range of the Reference Power Offset is 0-29, and the Power Offset value is obtained through simulation analysis according to actual test. The reference E-TFCI and the reference E-TFCI Power Offset are both configured by higher layer signaling.
The reference E-TFCI and the reference power offset play a role in converting power of different service rates when the UE transmits data in each transmission time interval TTI. The actual application process is shown in formula 1:
wherein: beta is a ed，ref Is ReferenceE-tfciower offset set in table 1 above;
K e，ref the size of the corresponding TBSize in the table 1 for the reference E-TFCI configured in the above table 2;
L e，ref to transmit K e，ref The number of E-DPDCH required for data volume;
K e，j representing the data volume to be transmitted by the UE in each TTI;
L e，j indicating transmission K e，j The number of E-DPDCH required for data volume;
Δ harq a bias constant for the service;
β ed，j，harq indicating transmission K e，j The power offset value that the data amount needs to use.
Wherein L is e，ref Or L e，j Needs to be calculated according to the following steps when calculating L e，reft When N is present e，j ＝K e，ref (ii) a When calculating L e，j When N is present e，j ＝K e，j ：
1. Determining the number N of all CCTrCH (code multiplexed transport channels) bits e，data Composed CCTrCH bit number corpusSubset SET0 included in SET;
CCTrCH bit number corpus SET = { N = { (N) } 256 ，N 18 ，N 64 ，N 32 ，N 16 ，N 8 ，N 4 ，2×N 4 ，2×N 2 ， 2×N 2 +2×N 4 }；
The subset SET0 is determined according to the self transmission capability of the UE and the number of CCTrCH bits allowed to be used by the UE by the network side, and each element N in the subset SET0 e，data The number of CCTrCH bits allowed to be used by the UE and the network side should be less than or equal to the number of CCTrCH bits, and the CCTrCH bits are configured in the process of establishing connection between the user and the network.
Each element N e，data Where N is the number of bits of the CCTrCH of one E-DPDCH channel at the corresponding SF, the index of N is the corresponding SF, SF is 256, 128, 64, 32, 16, 8, 4 or 2, and the coefficient multiplied by N is the number of E-DPDCHs allowed to be used by the UE. E.g. N 256 The bit number of the CCTrCH is expressed when the number of the E-DPDCH is 1 and the corresponding spreading factor is 256; 2 XN 4 The bit number of the CCTrCH is expressed when the number of the E-DPDCH is 2 and the corresponding spreading factor is 4; 2 XN 2 +2×N 4 The bit number of the CCTrCH when the number of E-DPDCH is 4 and the corresponding spreading factor of each two of the E-DPDCH is 2 or 4 respectively.
2. Determine SET1= { in SET0, N e，data Satisfies N e，data -N e，j The set of > =0 };
wherein N is e，j Indicating the maximum total allowed UE transmission per TTI for transport format j before rate matchingA number of bits;
each element N in the SET1 e，data The total number of bits allowed to be transmitted by the UE per TTI corresponding to the current transport format j should be equal to or greater than.
3. If SET1 is not empty and the smallest N in SET1 e，data If the corresponding E-DPDCH number is 1, directly making N e，data，j = minSET1, i.e. L e，ref Or L e，j If so, ending the calculation, otherwise, performing the step 4;
wherein N is e，data，j Indicating the total number of bits that the UE is allowed to transmit per TTI corresponding to transport format j.
Firstly, in a SET SET1, the minimum N which has the E-DPDCH number of 1 and can meet the transmission capability requirement without punching data sent by UE is preferentially selected e，data (ii) a Otherwise, the subsequent steps are carried out for selection.
4. Determine SET2= { in SET0, N e，data Satisfies N e，data -PL non-max ×N e，j The set of > =0 };
wherein PL non-max Puncturing limit value, 1-PL, indicating high layer configuration non-max Is 0.44.
If the SET2 is not empty, step 5 is performed; otherwise, executing step 6;
5. let N e，data，j Equal to the minimum N of 1 for the corresponding number of E-DPDCH in SET2 e，data That is, after the spread spectrum data sent to each TTI of the UE is preferentially selected to be punctured according to the puncturing limit value configurable by the upper layer, the minimum N that can satisfy the transmission capability requirement when the number of E-DPDCHs is 1 is selected e，data 。
If L is determined according to the above steps e，ref Or L e，j If yes, the calculation is finished; otherwise, continue to step 6.
6. If the SET2 is empty, that is, after the perforation is performed according to the perforation limit value which can be configured by the high layer, the transmission capability which can not meet the requirement still can be met, directly enabling N e，data，j Equal to SET0, satisfies N e，data -PL max × N e，j Maximum N of > =0 e，data 。
Wherein PL is max Indicating a puncturing limit value determined by the UE capability, except for UE support and network support N e，data ＝2×N 2 +2×N 4 The user value of (2) is not 0.33, but is 0.44 in other cases.
I.e. the puncturing limit value PL, again determined according to the UE capabilities max Is selected from SET0 to be fullMaximum N of transmission capacity requirement after punching e，data 。
In summary, if the minimum CCTrCH bit number exists in the SET0 and the number of E-DPDCH channels corresponding to the minimum CCTrCH bit number is 1, the second E-DPDCH channel number is SET to be 1 and then ended; otherwise:
according to the maximum punching limit value configured at the network side, the corresponding transmitted data volume (K) e，ref Or K e，j ) After the puncturing process is performed, if the number of CCTrCH bits capable of meeting the transmission capability exists in the SET0 and the number of the corresponding E-DPDCH channels is 1, let L be e，ref Or L e，j 1, if there are CCTrCH bit numbers which can satisfy the transmission capability but the number of the corresponding E-DPDCH channels is not 1, let L be e，ref Or L e，j Ending after the number of the E-DPDCH channels corresponding to the maximum CCTrCH bit number; otherwise:
according to the puncturing limit determined by the user equipment capability, for the corresponding transmitted data quantity (K) e，ref Or K e，j ) After the punching processing is carried out, the maximum CCTrCH bit number which can meet the transmission capability in the SET0 is inquired, and the L is ordered e，ref Or L e，j The number of E-DPDCH channels corresponding to the maximum CCTrCH bit number.
By way of specific example:
scene 1: suppose the amount of data that needs to be transmitted per TTI is (N) 32 + 1), then SET1= { N) that satisfies the condition 16 ，N 8 ，N 4 ，2×N 4 ，2×N 2 ，2×N 2 +2×N 4 }; then N is finally selected e，data，j ＝N 16 ；
Scene 2: assume that the amount of data to be transmitted is (1.25 x (2 x N) 4 ))，PL non-max 0.8, SET1= {2 × N) satisfying the condition according to the above-described procedure 2 ，2×N 2 +2×N 4 And since the number of the E-DPDCH corresponding to the minimum value of the SET1 is 2, the condition of the step 3 cannot be met, and the step 4 is executed and thenProcedure, SET2= {2 × N is obtained 4 ，2×N 2 ，2×N 2 +2×N 4 Get N according to the above process e，data，j ＝ 2×N 4 ；
Scene 3: assume that the amount of data that needs to be transmitted is 0.8 x (2 x N) 2 +2×N 4 ) Configuring PL non-max 0.9, then SET1= {2 × N 2 +2×N 4 }; and SET2= empty SET; so that N is finally obtained e，data，j ＝2×N 2 +2×N 4 。
From the above process, L is affected e，j Or L is e，ref Is mainly the configured PL non-max Puncturing limit, PL determined by UE and network side max Puncturing limit and the number of bits that need to be transmitted.
In table 3, the protocol 25.306 specifies the capability class of the UE, and it is understood from the table that different capability classes of UEs exist and different capability specifications exist.
Table 3UE capability class table
| UE capability class | Number of E-DPDCH | Minimum spreading factor | Maximum total number of bits allowed to be transmitted per TTI |
| Category 1 | 1 | SF4 | 7110 |
| Category 2 | 2 | SF4 | 14484 |
| Category 3 | 2 | SF4 | 14484 |
| Category 4 | 2 | SF2 | 20000 |
| Category 5 | 2 | SF2 | 20000 |
| Category 6 | 4 | SF2 | 20000 |
If the reference E-TFCI setting exceeds the UE capability and the bit number limit of the CCTrCH allowed to be used by the UE at the network side, the SET1 determined according to the SET0 is an empty SET and cannot be usedTo obtain L e，ref E.g. SET0= { N determined according to UE capability and the number of bits of CCTrCH allowed to be used by UE at network side 256 ， N 128 ，N 64 ，N 32 ，N 16 ，N 8 ，N 4 Refer to N corresponding to E-TFCI e，j ＝2×N 4 SET1 is then an empty SET, eventually perhaps according to PL non-ma And PL max L still cannot be determined e，ref Thereby resulting in beta ed，j，harq The configuration fails.
