Description

Dispatch non-dispatching multiplex and determine the transmission method of transport module size and modulation system

Technical field

The present invention relates to the high-speed uplink packet access technique in the wireless telecommunication system, relate in particular in the TD-SCDMA system, the MAC layer scheduling of HSUPA (high speed uplink packet access) and the method for non-dispatching multiplex transmission.

In 3-G (Generation Three mobile communication system), for the upstream packet business of higher rate is provided, improve spectrum utilization efficiency, 3GPP (3rd Generaion Partnership Project) has introduced high speed uplink packet access (HSUPA in the standard of WCDMA and TD-CDMA system, High SpeedUplink Packet Access) characteristic, promptly up enhancing characteristic.The HSUPA system ascending reinforcement system that is otherwise known as abbreviates the E-DCH system as.In the TD-CDMA system, the HSUPA system physical layer is introduced the E-PUCH physical channel, is used to transmit the CCTrCH of E-DCH type.

There are two kinds of business among the HSUPA: dispatching services and non-scheduling service.Dispatching services is to distribute code channel, time slot and power resource by Node B (NodeB); And non-scheduling service comes Resources allocation by service wireless network controller (SRNC).Non-scheduling resource generally is to occur in the cycle, therefore, when the data volume of having distributed non-scheduling resource but not have non-scheduling service or a non-scheduling service very hour, if utilize unnecessary non-scheduling resource to come the transmitting and scheduling business, then can farthest avoid the wasting of resources.Here it is the scheduling and the meaning of non-dispatching multiplex.

Scheduling and non-scheduling are meant that the multiplexing of MAC layer the data of scheduling and non-scheduling service are merged into a TBS (transmission block size, Transport Block Size) in the MAC layer transmit.In physical layer, this multiplexing TBS is carried out unified CRC (cyclic redundancy check (CRC)) verification and coding and decoding, therefore the data mixing of scheduling and non-scheduling service is transmitted together, and is indivisible.

In the prior art, dispatching services and non-scheduling service be transmission separately, because the SF (spreading factor) that scheduling and non-scheduling resource use possibility is different, and the timeslot number difference, thus cause the waste of resource.

Summary of the invention

Embodiment

Below in conjunction with drawings and the specific embodiments technical solution of the present invention is described in further detail.

In order to realize carrying out multiplexingly, make various resources effectively to utilize, the key technology for being selected to of TBS in multiplexing to scheduling and non-scheduling resource.

In the present embodiment, as shown in Figure 1, at first dispatching services and non-scheduling service are distinguished.If non-scheduling service is arranged, whether no matter dispatching services arranged, then be referred to as non-scheduled transmission, use the Process ID and the E-HICH channel of non-scheduling; If have only dispatching services, then be referred to as scheduled transmission, use the Process ID and the E-HICH channel of scheduling; That is to say that when existing dispatching services also has non-scheduling service transport layer is combined among the TBS all business as non-scheduled transmission, corresponding physical layer and MAC structure are as shown in Figure 1.

The general thought of present embodiment is as follows: at scheduling and the possible altogether code channel time interval resource quantity of non-scheduling, with the mode of possible total resources quantity according to the normalization equivalence, be divided into N hierarchical resource, and determine to have I the optional value of TBS in each grade, TBS resource table at a N * I of MAC layer design precomputes various possible TBS values in table; Secondly, when scheduling and non-scheduling service exists simultaneously and the non-scheduling service data volume can carry less than the Radio Resource of configuration bit number, the non-scheduled transmission of the definite employing of MAC layer promptly need be transmitted scheduling and non-scheduling service multiplexing; Once more, user equipment (UE) calculates the scheduling and the total resources of actual allocated, after considering the power authorization conditions again, from the TBS table of design, select the TBS value of corresponding TBS when multiplexing, UE is transferred to Node B (NodeB) with selected TBS index, Node B is also calculated the scheduling and the non-scheduling resource total amount of actual allocated, and determines the TBS value of Node B in view of the above with the TBS index that receives, and the modulation system of utilizing UE to send is carried out demodulation.

As shown in Figure 2, shown the method for designing of the TBS when realizing scheduling and non-dispatching multiplex in the present embodiment, comprised the steps:

Step 201: calculate scheduling and the possible altogether code channel time interval resource quantity of non-scheduling, and the code channel time interval resource quantity of gained is divided into N hierarchical resource, design I the optional value of TBS that has in each hierarchical resource, at MAC layer design TBS resource table.

Step 202: when scheduling and non-scheduling service when existing simultaneously and the non-scheduling service data volume can carry less than the Radio Resource of configuration bit number the time, the non-scheduled transmission of the definite employing of MAC layer promptly need be transmitted scheduling and non-scheduling service multiplexing.

Step 203:UE calculates the scheduling and the non-scheduling resource total amount of actual allocated, and in view of the above and the power mandate from the TBS resource table, select TBS, and definite modulation system, concrete steps as shown in Figure 3.

Step 204: by UCCH, UE is transferred to NodeB with the index of selected TBS.

Step 205:NodeB calculates the scheduling and the non-scheduling resource total amount of actual allocated, and carries out demodulation with the modulation system that receives, and detailed process as shown in Figure 4.

In described step 201, the detailed process of the optional value of design TBS resource is as follows.

(1) at first, determine a resource units (RU, Resource Unit), the solid size road with SF=16 in the present embodiment is defined as basic resource units (RU).

(2) then, possible maximum resource quantity and minimum resource quantity are determined in normalization according to Resource Unit.

Because the resource that scheduling and non-scheduling take altogether is at most the full code channel of 5 time slots, minimum is the code channel of a SF=16 of single time slot.That is to say to take 80 basic RU at most, minimum takies 1 basic RU.

(3) next, with the mode of step 2 kind of possible total resources quantity according to the normalization equivalence, be divided into N hierarchical resource, N is relevant with modulation system, and can be divided exactly by 80.

N=5 in the present embodiment, promptly divide 5 hierarchical resources:

1～16 RU of the first estate correspondence; 17～32 RU of the second grade correspondence; 33～48 RU of tertiary gradient correspondence; 49～64 RU of fourth estate correspondence; 65～80 RU of the 5th grade correspondence.

(4) afterwards, at each hierarchical resource, need maximum TBS value and minimum TBS value in definite each grade.

What the minimum value of TBS was got is the bit number 23 of schedule information;

The maximum number bits that the maximum of TBS should corresponding SF=1, modulation system may be transmitted during for 16QAM, therefore, the maximum of TBS satisfies following formula in N hierarchical resource as can be seen:

$\frac{\mathrm{TBS}/M\×\mathrm{SF}}{704-17\×\mathrm{ENI}\×\mathrm{SF}-(24+\mathrm{ceil}((\mathrm{TBS}+24)/5114)\×4)/M\×\mathrm{SF}+704(t-1)}=1$

Wherein, the 17th, 17 symbols that UCCH takies, 24 correspondences be the number of CRC check bit, 4 correspondences be Turbo coding and the tail bit that carries over through punching, M is the value of modulation system correspondence, and during QPSK, M=2 is during 16QAM, M=4, Ceil is the number that rounds up, t is a timeslot number; ENI is the E-UCCH number;

Can obtain the maximum of TBS in N the different resource grade by following formula:

When N=1, TBSmax=2720;

When N=2, TBSmax=5532;

When N=3, TBSmax=8348;

When N=4, TBSmax=11160;

When N=5, TBSmax=13976.

(5) last, after the TBS maximum and minimum value in having determined each hierarchical resource, need be between TBS maximum in each hierarchical resource and minimum value the some TBS values of equally spaced insertion, wherein, public technology document " Ericsson.R1-02-DRAFT; Signaling ofTransport Block Sizes for HS-DSCH " according to Ericsson, TBS should evenly distribute in log-domain, can reduce the length of the padding under the worst case, therefore when carrying out interpolation, we are according to I TBS in each hierarchical resource in this principle design HSUPA system, that is, and and during interpolation, TBS maximum and minimum value are taken the logarithm, carry out even interpolation in log-domain, the logarithm value that interpolation is obtained is converted to corresponding TBS numerical value again, thereby can obtain I TBS value having in each hierarchical resource.

For example, in the present embodiment, 14 TBS values of insertion as shown in table 1 are even there are 16 TBS values in each hierarchical resource.So just obtained TBS resource table as shown in table 1.Can be 32 TBS values in other embodiments of the invention, or 2048 TBS values.

By above step (1)～(5), we can obtain might resource situation under corresponding TBS resource table, as shown in table 1:

TBS value when table 1:HSUPA MAC is multiplexing under the different resource unit

INDEX	The TBS of N=1	The TBS of N=2	The TBS of N=3	The TBS of N=4	The TBS of N=5
						0	23	23	23	23	23
1	32	33	34	35	35
						2	43	48	50	52	54
3	60	69	75	79	83
						4	82	99	111	120	127
5	113	143	164	181	195
						6	155	206	243	273	299
7	213	297	360	412	458
						8	293	428	533	623	702
9	403	617	790	940	1076
						10	554	890	1170	1420	1650
11	762	1282	1734	2145	2530

12	1047	1848	2568	3239	3878
						13	1439	2663	3804	4893	5946
14	1979	3838	5635	7389	9116
						15	2720	5532	8348	11160	13976

In the TBS resource table shown in the table 1, first classifies the TBS index value as, and value is 0～15, respectively corresponding 5 hierarchical resources of secondary series to the six row.

Because we adopt the solid size road of SF=16 as the RU of basic resources unit, the scheduling and the non-scheduling resource that have different SF so can normalize on the basic RU, addition promptly obtains reality resource quantity altogether, and then comes to select corresponding TBS according to total resources from the TBS resource table shown in the table 1.

In step 203 shown in Figure 2, UE calculates the scheduling of actual allocated and the step of non-scheduling resource total amount, and in view of the above and the power mandate from the TBS resource table, select TBS, and definite modulation system can be subdivided into following concrete steps, with reference to shown in Figure 3:

Step 301: the independent RU stock number of calculating scheduling resource and non-scheduling resource.

If scheduling resource is: ts_s (scheduling time slot corresponding resource), sf_s (spreading factor that scheduling is corresponding); If non-scheduling resource is: ts_ns (non-scheduling time slot corresponding resource), sf_ns (spreading factor of non-scheduling correspondence);

Scheduling resource and non-scheduling resource are all converted on the resource of SF=16, and conversion back scheduling/non-scheduling RU resource is respectively:

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

Above-mentioned two formula processs for: utilize the SF=16 basic resource unit independently the time-slot code channel resource of scheduling/non-scheduling to be carried out normalized respectively, obtain the RU number N _ s of scheduling resource and the RU number N _ ns of non-scheduling resource.Wherein, SF=16, i_s represent i time slot scheduling, should be i_s=1 in the following formula, and similarly, i_ns represents i non-time slot scheduling, i_ns=1, whole formulate be from 1 be added to ts_s or ts_ns, promptly a plurality of time slots and.

Step 302: the independent TBS that calculates scheduling resource and non-scheduling resource correspondence.

According to the scheduling/non-scheduling RU number N _ s and the N_ns of conversion, each self-corresponding TBS of selection scheduling and non-scheduling organizes from 5 groups of TBS resources shown in the table 1 respectively;

In the present embodiment, as shown in table 1, the TBS resource is divided into 5 groups altogether in the table 1, and every group of corresponding RU resource is respectively:

The 1st group: N=[1,16]; The 2nd group: N=[7,32];

The 3rd group: N=[33,48]; The 4th group: N=[49,64];

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

So Dui Ying scheduling/non-scheduling TBS set of resources is not:

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

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

Wherein, index_group_TBS_s, index_group_TBS_ns represent TBS resource group index and the TBS resource group index of non-scheduling, i.e. Dui Ying N value, the just group number of dispatching respectively.

After in above-mentioned steps 302, finding scheduling and each self-corresponding resource group of non-scheduling, promptly obtain corresponding group number.How following step is being dispatched in the resource group separately if will being introduced/the corresponding TBS value of non-scheduling, promptly in the group of correspondence, search the TBS index, and find the position of the row in the table 1.

Step 303:, calculate different modulating mode and transmission means corresponding code rate λ value according to different modulation systems and different transmission meanss.

Described modulation system can be QPSK modulation or 16QAM modulation; Described transmission means can be scheduled transmission or non-scheduled transmission.Utilize following four formula, can obtain 4 λ values under different modulating mode and the different transmission meanss:

λ_QPSK_ns＝TBS_group_ns/N_ns/88；

λ_16QAM_ns＝TBS_group_ns/N_ns/176；

λ_QPSK_s＝TBS_group_s /N_s/88；

λ_16QAM_s＝TBS_group_s/N_s/176；

Wherein, TBS_group_s is meant the group TBS (being 16 in table 1 altogether) of scheduling resource correspondence, and TBS_group_ns is meant the group TBS (being 16 in table 1 altogether) of non-scheduling resource correspondence.

Group number index_group_TBS_s according to step 302 selection, index_group_TBS_ns, calculate scheduling respectively, this group TBS (16 TBS of non-scheduling resource correspondence, in certain delegation in the correspondence table 1 16 row) code check, because modulation system has 2 kinds, therefore, calculates 2 kinds of modulation system corresponding code rate respectively.

Step 304: in scheduling and each self-corresponding TBS resource group of non-scheduling, select the TBS value of code check λ in specified scope.

Because UE is in application UPA business, NodeB can dispose one group of maximum/minimum code rate λ _ max/ λ _ min and give UE, need to select λ to satisfy the TBS value that λ _ max/ λ _ min requires, promptly select for the first time, select to satisfy the TBS that code check requires in 32 TBS values from original a group, TBS scope=A, A＜=32, symbolic formulation is as follows:

For non-scheduling:

QPSK_index_ns＝find(λ_QPSK_ns(find((λ_QPSK_ns＜λ_max)＞λ_min)))

16QAM_index_ns＝find(λ_16QAM_ns(find((λ_16QAM_ns＜λ_max)＞λ_min)))

λ_QPSK_1_ns＝λ_QPSK_ns(QPSK_index_ns)

λ_16QAM_1_ns＝λ_16QAM_ns(16QAM_index_ns)

TBS_QPSK_1_ns＝TBS_QPSK_ns(QPSK_index_ns)

TBS_16QAM_1_ns＝TBS_16QAM_ns(16QAM_index_ns)

For scheduling:

QPSK_index_s＝find(λ_QPSK_s(find((λ_QPSK_s＜λ_max)＞λ_min)))

16QAM_index_s＝find(λ_16QAM_s(find((λ_16QAM_s＜λ_max)＞λ_min)))

λ_QPSK_1_s＝λ_QPSK_s(QPSK_index_s)

λ_16QAM_1_s＝λ_16QAM_s(16QAM_index_s)

TBS_QPSK_1_s＝TBS_QPSK_s(QPSK_index_s)

TBS_16QAM_1_s＝TBS_16QAM_s(16QAM_index_s)

Step 305: according to 8 reference power biasings with reference to the sub-TBS needs of code check λ value interpolation calculation correspondence.

UE when application UPA is professional, Node B will dispose 8 with reference to the λ value and in requisition for power, according to physical layer difference TBS, the different modulating mode selects corresponding code rate to calculate at the Ior/Ioc at BLER=0.1 place.

The power of E_PUCH is: P _E-PUCH=P _E-base+ L+ β _e+ K _E-PUCH

Wherein, β _eBe gain factor, 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 _HarqDB, 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)

Obtain after the interpolation:

β _0e_ QPSK_ns represents the reference power of non-scheduled transmission QPSK needs;

β _0e_ 16QAM_ns represents the reference power of non-scheduled transmission 16QAM needs;

β _0e_ QPSK_s, the reference power that expression scheduled transmission QPSK needs;

β _0e_ 16QAM_s, the reference power that expression scheduled transmission 16QAM needs;

Step 306: whether the power under the TBS of more different respectively transport-type correspondences is less than or equal to the authorization power of this transport-type; Interpolation result according to step 305 calculating, the TBS (set B) that requires through the power mandate of selecting to satisfy the type (transferring non-scheduling) among the TBS (set A) that selects for the first time respectively from step 304 promptly selects for the second time, obtain set B, make set B＜set A.

The symbolic formulation mode is as follows:

β _0e_QPSK_ns_after_β _{0e_NS}＝β _0e_QPSK_ns(find(β _0e_QPSK_ns＜β _{0e_NS}))

β _0e_16QAM_ns_after_β _{0e_NS}＝β _0e_16QAM_ns(find(β _0e_16QAM_ns＜β _{0e_NS}))

β _0e_QPSK_s_after_β _{0e_S}＝β _0e_QPSK_s(find(β _0e_QPSK_s＜β _{0e_S}))

β _0e_16QAM_s_after_β _{0e_S}＝β _0e_16QAM_s(find(β _0e_16QAM_s＜β _{0e_S}))

Step 307: compare with UE BUFFER, select TBS less than UE BUFFER.Wherein,, from set B, select the type (scheduling, non-scheduling) to satisfy the set that buffer requires respectively, promptly gather C, make set C＜set B according to the result of step 306;

The symbolic formulation mode is as follows:

TBS_QPSK_after_buffer_ns＝TBS_QPSK_ns(find(TBS_QPSK_1_ns＜UE_Buffer))

TBS_16QAM_after_buffer_ns＝TBS_16QAM_ns(find(TBS_16QAM_1_ns＜UE_Buffer))

TBS_QPSK_after_buffer_s＝TBS_QPSK_s(find(TBS_QPSK_1_s＜UE_Buffer))

TBS_16QAM_after_buffer_s＝TBS_16QAM_s(find(TBS_16QAM_1_s＜UE_Buffer))

Step 308: respectively from two kinds of transmission meanss, select in two kinds of modulation systems to satisfy the authorization power requirement, and the TBS maximum.When the maximum TBS that selects when two kinds of modulation systems was identical, the relatively power configuration of corresponding needs skew selected the power configuration skew little.

That is, if the power that the power that the QPSK of non-scheduling resource needs needs smaller or equal to the 16QAM of non-scheduling resource, then selecting modulation mode is QPSK, otherwise selects 16QAM;

If the power of the QPSK of scheduling resource needs is smaller or equal to the power of the 16QAM needs of scheduling resource, then selecting modulation mode is QPSK, otherwise selects 16QAM.

The symbolic formulation mode is as follows:

if(β _0e_QPSK_ns＞β _0e_16QAM_ns)：type_mod_ns＝16QAM

if(β _0e_QPSK_ns＜＝β _0e_16QAM_ns)：type_mod_ns＝QPSK

if(β _0e_QPSK_s＞β _0e_16QAM_s)：type_mod_s＝16QAM

if(β _0e_QPSK_s＜＝β _0e_16QAM_s)：type_mod_s＝QPSK

Step 309: final TBS value final_TBS and the TFC value of determining to upload to nodeB.

If scheduling, the modulation system that non-scheduling is selected is identical, then:

With two independent direct additions of selecting of TBS value, and in the TBS table, find the most approaching but less than the TBS value after the stack as final TBS.

If scheduling, the modulation system difference that non-scheduling is selected, then:

If the TBS that scheduling is selected is invalid, then

The final TBS that selects is the TBS of non-scheduling, and modulation system is the modulation system that non-scheduling is selected;

If the TBS that non-scheduling is selected is invalid, then

The final TBS that selects is the TBS of scheduling, the modulation system that modulation system is selected for scheduling;

If scheduling, the TBS that non-scheduling is selected is effective, then:

If the TBS of non-scheduling is greater than the TBS of scheduling, then

Final TBS is non-scheduling TBS+ (identical with non-scheduling modulation system and TBS maximum among the TBS that scheduling is selected), and perhaps final TBS is non-scheduling TBS; Final modulation system is the modulation system that non-scheduling is selected;

If the TBS of scheduling is greater than the TBS of non-scheduling, then

Final TBS is scheduling TBS+ (identical with the scheduling modulation system and TBS maximum among the TBS that non-scheduling is selected), and perhaps final TBS is scheduling TBS; The modulation system that final modulation system is selected for scheduling.

The symbolic formulation mode is as follows:

if(type_mod_ns≠type_mod_s)

if(TBS_ns≠0&TBS_s＝＝0)

then：final_TBS＝TBS_ns，type_mod＝type_mod_ns；

if(TBS_ns＝＝0&TBS_s≠0)

then：final_TBS＝TBS_s，type_mod＝type_mod_s；

if(TBS_ns≠0&TBS_s≠0)

if(TBS_ns＞TBS_s)，then：final_TBS＝TBS_ns+max(TBS_s(type_mod_ns))

type_mod＝type_mod_ns；

if(TBS_ns＜＝TBS_s)，then：final_TBS＝TBS_s+max(TBS_ns(type_mod_s))，

type_mod＝type_mod_s；

Step 310: in TBS set, select in the corresponding group in RU conversion back and the final_TBS that chooses in the above-mentioned steps 309 is the most approaching and smaller or equal to the value of this final_TBS:

final_TBS_index＝max(find((final_TBS-TBS_group)＞＝0))

As shown in Figure 4, in step 205 shown in Figure 2, NodeB obtains the TBS value also according to the part of each step shown in Figure 3, and process is as follows:

Step 401: conversion RU.

Total RU resource translation method is as follows:

If scheduling resource is: ts_s, sf_s;

Non-scheduling resource is: ts_ns, sf_ns;

Scheduling and non-scheduling resource are all converted on the resource units of SF=16, and the total resource in conversion back is:

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

Step 402: according to total RU number of resources N of conversion, and UE sends to the TBS index final_TBS_index of NodeB, the corresponding TBS value of selection from 5 groups of TBS resources;

index_TBS_NodeB＝ceil(N/16)

TBS_nodeB＝TBS_set(index_TBS_NodeB，final_TBS_index)

The resource N that calculates according to step 401 converts on 16 code channels, and rounds up, and determines TBS selects in the table 1 row number.(of selecting in 16 the insides from table 1, at once number) reports Node B by E-UCCH because final TBS, and therefore, Node B can know selected TBS according to above-mentioned two information.Because modulation system is to show to transmit, so Node B side does not need to calculate modulation system again.
