The scheduling that step b, UE distribute respectively according to NodeB and SRNC and SF and the timeslot number of non-scheduling resource, convert by following formula the basic RU number that both occupy separately:

1) for the time slot that only has scheduling or non-scheduled mandate

$\mathrm{RU}\_{\mathrm{number}}_{\mathrm{schedual}}=(\frac{16}{{\mathrm{SF}}_{\mathrm{schedual}}}*N\_{\mathrm{TS}}_{\mathrm{schedual}}+\frac{16}{{\mathrm{SF}}_{\mathrm{overlap}}}*N\_{\mathrm{TS}}_{\mathrm{overlap}}*\frac{{\mathrm{SF}}_{\mathrm{non}\_\mathrm{schedual}}}{{\mathrm{SF}}_{\mathrm{schedual}}+{\mathrm{SF}}_{\mathrm{non}\_\mathrm{schedual}}})*P_s$

$\mathrm{RU}\_{\mathrm{number}}_{\mathrm{non}\_\mathrm{schedual}}=(\frac{16}{{\mathrm{SF}}_{\mathrm{non}\_\mathrm{schedual}}}*N\_{\mathrm{TS}}_{\mathrm{non}\_\mathrm{schedual}}+\frac{16}{{\mathrm{SF}}_{\mathrm{overlap}}}*N\_{\mathrm{TS}}_{\mathrm{overlap}}*\frac{{\mathrm{SF}}_{\mathrm{schedual}}}{{\mathrm{SF}}_{\mathrm{schedual}}+{\mathrm{SF}}_{\mathrm{non}\_\mathrm{schedual}}})*P_{\mathrm{ns}}---\left(1\right)$

SF wherein _Overlap=min{SF _Schedual, SF _{Non_schedual}Scheduling and the overlapping time slot of non-scheduled mandate.P _s∈ (0,1] be the scheduled transmission weight coefficient, P _ns∈ (0,1] be the scheduled transmission weight coefficient.SF _{Non_schedual}And SF _SchedualIt is respectively non-scheduled and scheduling resource spreading factor used.N_TS _{Non_schedual}And N_TS _SchedualIt is respectively non-scheduled and the shared non-overlapped timeslot number of scheduling resource.N_TS _OverlapIt is non-scheduled and scheduling resource overlapping slot number.

Can obtain thus dispatching the basic RU number that altogether takies with non-scheduling resource and the spreading factor SF of multiplexing rear equivalence _MultiplexFor

RU_number _multiplex＝RU_number _schedual+RU_number _{non_schedual}+RU_number _overlap (2)

${\mathrm{SF}}_{\mathrm{multiplex}}=\frac{{\mathrm{SF}}_{\mathrm{schedual}}\×N\_{\mathrm{TS}}_{\mathrm{schedual}}+{\mathrm{SF}}_{\mathrm{non}\_\mathrm{schedual}}\×N\_{\mathrm{TS}}_{\mathrm{non}\_\mathrm{schedual}}+{\mathrm{SF}}_{\mathrm{overlap}}\×N\_{\mathrm{TS}}_{\mathrm{overlap}}}{N\_{\mathrm{TS}}_{\mathrm{schedual}}+N\_{\mathrm{TS}}_{\mathrm{non}\_\mathrm{schedual}}+N\_{\mathrm{TS}}_{\mathrm{overlap}}}---\left(3\right)$

Step c, UE is by RU_number _MultiplexWhich hierarchical resource the total resources of judgement actual allocated has dropped in, and finds corresponding row in table 1.Then select the TBS of a maximum in corresponding row.

Steps d is according to RU_number _SchedualAnd RU_number _{Non_schedual}, by formula (4), (5), TBS is pro rata distributed to scheduling and non-scheduling service.

Step e calculates respectively TBS by formula (6) _SchedualAnd TBS _{Non_schedual}Corresponding code check

$\mathrm{\λ}=\frac{\mathrm{TBS}}{R_e}---\left(6\right)$

R wherein _eIt is the bit number that scheduling and non-scheduled physical channel can transmit.R _eRelevant with modulation system, therefore obtain at last four code check value λ _{Schedual, QPSK}, λ _{Non_schedual, QPSK}, λ _{Schedual, 16QAM}, λ _{Non_schedual, 16QAM}, be respectively the code check under scheduling resource QPSK modulation system, the code check under non-scheduling resource QPSK modulation system, the code check under scheduling resource 16QAM modulation system, the code check under non-scheduling resource 16QAM modulation system.

Step f judges whether to have at least scheduling corresponding to a kind of modulation system and non-scheduled code check value to drop in the minimax range of code rates of high-rise configuration.If not changing step h over to; If so, by the one group of reference power β value that configures with UTRAN that enters that falls in the minimax range of code rates, through type (7) interpolation obtains into corresponding performance number β _{0, e}

${\mathrm{\β}}_{0,e}={\mathrm{\β}}_{\mathrm{\λ}0}+\frac{{\mathrm{\β}}_{\mathrm{\λ}1}-{\mathrm{\β}}_{\mathrm{\λ}0}}{{\mathrm{\λ}}_1-{\mathrm{\λ}}_0}({\mathrm{\λ}}_e-{\mathrm{\λ}}_0)\mathrm{dB}---\left(7\right)$

On this basis, rated output biasing

β _e＝β _0，e+a _e+Δ _HARQ (8)

α wherein _eBe and spreading factor SF _MultiplexCorresponding power weightings value.Δ _HARQBe high-rise for retransmitting a parameter that arranges, see [2].

As shown in the above, the power bias of the corresponding group scheduling of a kind of modulation system and non-scheduling resource

Relatively under QPSK and 16QAM modulation system, dispatch and non-scheduled needed power bias

Whether be less than or equal to the power mandate of scheduling and non-scheduling resource.If only have the power bias of scheduling corresponding to a kind of modulation system and non-scheduling resource to satisfy above-mentioned requirements, keep this modulation system and TBS.If the power bias under two kinds of modulation systems all can satisfy the power mandate, calculate so that under two kinds of modulation systems, two kinds of needed gross power biases of resource are

${\mathrm{\β}}_{e,\mathrm{QPSK}}={\mathrm{\β}}_{e_{\mathrm{schedual},\mathrm{QPSK}}}+{\mathrm{\β}}_{e_{\mathrm{non}\_\mathrm{schedual},\mathrm{QPSK}}}$ (9)

${\mathrm{\β}}_{e,16\mathrm{QAM}}={\mathrm{\β}}_{e_{\mathrm{schedual},16\mathrm{QAM}}}+{\mathrm{\β}}_{e_{\mathrm{non}\_\mathrm{schedual},16\mathrm{QAM}}}$

Compare β _{E, QPSK}And β _{E, 16QAM}, select a less modulation system that value is corresponding.Keep this modulation system and TBS.If do not have power bias corresponding to a kind of modulation system to satisfy power mandate requirement, change step h over to.

Step g judges whether the TBS of above-mentioned reservation meets the Buffer requirement of UE, if meet, selected TBS is final selected TBS, and its index is transferred to NodeB.If do not meet, change step h over to.

Step h is at table 1RU_number _MultiplexReselect a maximum TBS less than current TBS in respective column, and repeat steps d～step h, until choose a satisfactory TBS.

Step I, UE is uploaded to NodeB with the corresponding index value of satisfactory TBS by UCCH.

Step j, NodeB calculates RU_number according to formula (1), (2), (3) _Schedual, RU_number _{Non_schedual}And RU_number _Multiplex, SF _MultiplexBy RU_number _Multiplex, NodeB finds the row of its correspondence in table 1, then by the TBS index that receives, NodeB finds corresponding TBS value.The TBS value that utilization is found can calculate respectively corresponding code check and power bias β for QPSK and 16QAM _e, select wherein to meet minimax constrained code rate, power mandate constraint and β _eLess the sort of modulation system is carried out demodulation.
