Step S406 can may further comprise the steps: the mode according to separate physical channel resource conversion physical channel total resources is divided TBS, or adopts the mode of not converting to divide TBS; After adopting definite minimum and maximum TBS in above-mentioned two kinds of methods, in the method for the linear uniform distribution TBS of log-domain.

The present invention proposes to adopt and divide amount of information grade in the buffer memory, and report NodeB, so that NodeB and UE have the parameter of equity, NodeB adopts identical rule with UE, with definite TBS and modulation system, thereby makes the utilization of resources more reliably flexible and efficient.Specifically:

1) prior art is that scheduling is generated different transmission blocks at the MAC layer respectively with non-scheduling service, uses respectively scheduling and non-scheduled physical channel resources in physical layer.In a single day resource distributes, and dispatching services can not use non-scheduled physical resource, and non-scheduling service can not use the physical resource of scheduling, has therefore caused the waste of resource.No matter multiplexing the present invention will dispatch and non-scheduling service is multiplexed into a TB at the MAC layer and transmits, be what business among the TB after, and physical layer can be used all scheduling and non-scheduled resources (such as Fig. 1), has improved the service efficiency of physical layer resources.

2) prior art is that scheduling and non-scheduling service independently select the then TBS of oneself according to separately power mandate and SF (spreading factor) difference, and upload the TBS indication by E-UCCH, this mode of independently uploading the TBS indication is unfavorable for scheduling, and non-scheduling service is multiplexing; The present invention proposes by E-UCCH and upload data volume hierarchy index in the UE buffer memory (UE Buffer) (in Fig. 2, content among the existing E-UCCH is revised, the E-UCCH structure can change also and can not change), make NodeB and UE have identical parameter amount and identical selective rule; The structure of E-UCCH comprises data 1 field, UE_buffer registration index field, RSN field, HARQ sequence number field, training sequence field, through-put power control field, data 2 fields and protection interval field as shown in Figure 2.

3) prior art does not have grade classification and the corresponding index of the data volume in the UE buffer memory (UE Buffer), the method of the grade classification of the data volume in the UE buffer memory (UE Buffer) has been proposed in the present invention, adopt the linear mode of evenly dividing of the linear even or non-log-domain of log-domain, and carry out Grade numbers, this numbering is corresponding with hierarchy index;

4) work as scheduling, non-scheduled in identical time slot, then to select spreading factor little, and will dispatch, non-scheduled authorization power addition is as total authorization power; Identical and in same code tree node lower time when spreading factor, adopt upper level code tree node; Identical and not in same code tree node lower time when spreading factor, select according to spread spectrum code channel sequence number, can select sequence number high or select sequence number low; Work as scheduling, non-scheduled not in identical time slot, can then adopt three kinds of modes, a kind of is independently resource of basis, selects satisfactory TBS; A kind of is that the mode that adopts the independent resource conversion to merge is selected TBS; A kind of is according to the independently rear nonjoinder of resource conversion, selects satisfactory TBS;

5) because the hierarchy index of the data volume in the UE buffer memory (UE Buffer) has been issued NodeB, NodeB has identical parameter with UE, under identical selective rule, TBS and modulation system that UE selects when sending data, the NodeB side can be according to identical parameter, and identical selective rule calculates TBS and the modulation system (such as Fig. 3) that UE selects, like this, the modulation system of each time slot can be the same or different, and has higher flexibility;

6) owing to can divide TBS according to the mode of resource (time slot, code channel) conversion, design a kind of new TBS set (such as table 1); Also can adopt the mode of not converting to divide TBS, as dividing TBS according to time slot, determine maximum, behind the minimum TBS, at the linear uniform distribution TBS of log-domain.

The below engages accompanying drawing and describes specific embodiments of the invention in detail.

RNC and NodeB distribute physical layer resources for respectively scheduling and non-scheduling service in known technology, and dispatching services can not use non-scheduled physical resource, and non-scheduling service can not use the physical resource of scheduling.Portable terminal sends signaling to NodeB by the E-UCCH among the E-PUCH, NodeB extrapolates the modulation system of the data of transmitting among the E-PUCH according to the TFCI of E-UCCH signaling, the modulation system that employing is extrapolated is carried out the step of demodulation to data, and the present invention adopts following method at MAC layer and physical layer multiplex scheduling and non-scheduling service, take independent conversion RU as example, concrete steps following (such as Fig. 3):

(1) scheduling resource and non-scheduling resource are independently converted RU:

If scheduling resource is: ts_s (timeslot number of scheduling resource), sf_s (spreading factor in each time slot of scheduling resource); Non-scheduling resource is: ts_ns (timeslot number of non-scheduling resource), sf_ns (spreading factor in each time slot of scheduling resource); All convert on the resource of SF=16 scheduling/non-scheduled RU resource after the conversion:

$N\_s=\underset{i\_s}{\overset{\mathrm{ts}\_s}{\mathrm{\Σ}}}{\left(\frac{\mathrm{SF}}{\mathrm{sf}\_s}\right)}_{i\_s}---\left(1\right)$

$N\_\mathrm{ns}=\underset{i\_\mathrm{ns}}{\overset{\mathrm{ts}\_\mathrm{ns}}{\mathrm{\Σ}}}{\left(\frac{\mathrm{SF}}{\mathrm{sf}\_\mathrm{ns}}\right)}_{i\_\mathrm{ns}}---\left(2\right)$

(2) the independent TBS that calculates

From 5 groups of TBS (such as table 1), select corresponding TBS group according to the scheduling of converting/non-scheduled RU;

TBS is divided into altogether 5 groups, and every group of corresponding RU resource is respectively:

First group: N=[1,16];

Second group: N=[7:32];

The 3rd group: N=[33,48];

The 4th group: N=[49:64];

The 5th group: N=[65:80];

So corresponding scheduling/non-scheduled TBS group is:

$\mathrm{index}\_\mathrm{group}\_\mathrm{TBS}\_\mathrm{ns}=\mathrm{ceil}\left(\frac{N\_\mathrm{ns}}{16}\right)---\left(3\right)$

$\mathrm{index}\_\mathrm{group}\_\mathrm{TBS}\_s=\mathrm{ceil}\left(\frac{N\_s}{16}\right)---\left(4\right)$

According to index_group_TBS_s (scheduling resource select TBS group index), index_group_TBS_ns (the TBS group index that non-scheduling resource is selected) dispatched/the TBS value of non-scheduled correspondence.

(3) calculate lamda:

According to different modulation systems, different transmission meanss are calculated the different modulating mode, the λ that transmission means is corresponding

λ _ QPSK_ns=TBS_group_ns/N_ns/88 (the non-scheduling resource modulation system is code check corresponding to QPSK)

λ _ 16QAM_ns=TBS_group_ns/N_ns/176 (the non-scheduling resource modulation system is code check corresponding to 16QAM)

λ _ QPSK_s=TBS_group_s/N_s/88 (the scheduling resource modulation system is code check corresponding to QPSK)

λ _ 16QAM_s=TBS_group_s/N_s/176 (the scheduling resource modulation system is code check corresponding to 16QAM)

(4) in the group of correspondence, select the TBS value of code check λ in specified scope

UE is in application UPA business, and NodeB can configure one group of maximum/minimum code rate λ _ max and λ _ min to UE, and the code check λ that above-mentioned steps (3) is calculated will be in this scope;

(5) according to 8 reference power biasings with reference to sub-TBS needs corresponding to code check λ value interpolation calculation

UE when application UPA is professional, NodeB will configure 8 with reference to λ value and in requisition for power, according to the different TBS of physical layer, the different modulating mode selects the Ior/Ioc of code check at the BLER=0.1 place of correspondence to calculate.

The power of E_PUCH is:

P _E-PUCH＝P _e-base+L+β _e+K _E-PUCH (5)

Wherein β e is gain factor, and E-TFC transport block length, E-PUCH physical resource size, the E-PUCH modulation system selected from UE obtain.

β _e＝β _0，e+α _e+Δ _harq?dB (6)

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

Obtain after the interpolation:

β _0eThe reference power that the non-scheduled transmission of _ QPSK_ns QPSK needs

β _0eThe reference power that the non-scheduled transmission of _ 16QAM_ns 16QAM needs

β _0eThe reference power that _ QASK_s scheduled transmission QPSK needs

β _0eThe reference power that _ 16QAM_s scheduled transmission 16QAM needs

(6) power under the TBS that more different transport-types are corresponding respectively whether less than/equal the type authorization power;

For interference being controlled in certain scope, system is to the different resource assigns authorized power of UE, and the power bias that step (5) is calculated will be in the authorization power of system assignment.

(7) respectively from two kinds of transmission meanss, select in two kinds of modulation systems to satisfy the authorization power requirement, and the modulation system of TBS maximum, when the maximum TBS that selects when two kinds of modulation systems is identical, the little modulation system of power configuration skew is selected in the relatively power configuration of corresponding needs skew.

(8) the TBS summation of definite carrying, calculate two kinds of resource selection TBS's and, and judge whether the grade greater than UE buffer, if less than would finish selection, enter (13), UE buffer grade is reported NodeB by UCCH, if greater than UE buffer grade, then enter (9).

(9) transport-type of selection TBS maximum, if TBS equates, the transmission means of preferential guaranteed output minimum then, if power is equal to, guarantee preferentially that then modulation system is the transmission means of QPSK, if modulation system all is QPSK, then have to guarantee first non-scheduled transmission, remaining data are the data volume that value-larger TBS transmits that UE Buffer grade indicates.

(10) judge whether remaining data volume can be transmitted in another resource type, if can, then in the TBS that in step (6), obtains set corresponding to the type resource, select the maximum TBS less than or equal to remaining data volume, enter (13); If cannot, then enter (11);

(11) judge whether another transport-type modulation system of residue is QPSK, if, then the TBS of another one transmission means can be 0, perhaps reducing code check transmits the TBS that selects in (9) in two dissimilar resources, perhaps remaining data volume is replenished invalid value, such as 0 value, make TBS coupling minimum in its data volume length and the TBS that in step (6), the obtains set, enter (13); If not QPSK, then enter (12);

When (12) modulation system of this transmission means is QPSK, is TBS in the corresponding TBS that obtains in step (6) set less than or equal to the remaining data amount? and satisfy power requirement, if, then in this set, select the maximum TBS less than or equal to remaining space, enter (13); If not, then the TBS of another one transmission means is 0, perhaps reducing code check transmits the TBS that selects in (9) in two dissimilar resources, perhaps remaining data volume is replenished invalid value, such as 0 value, minimum TBS mates in the TBS set that makes its data volume length and obtain in step (6), enters (12);

(13) at UE end, two TBS are combined into a compound TBS (represent total transmitted data amount), with the parameter of using in calculating: UE buffer grade is indicated, and directly issues NodeB in E-UCCH.

NodeB has the parameter identical with the UE side and selective rule and process, also according to said process, calculates modulation system and TBS value (being total transmitted data amount), carries out demodulation rate-matched and decoding.
