Description

Strengthen dedicated channel transport format collection system of selection and device

Technical field

The present invention relates to moving communicating field, especially refer to that a kind of High Speed Uplink Packet that is used for inserts (HighSpeed Uplink Packet Access, HSUPA) enhancing dedicated channel transport format collection (E-DCHTransport Format Combination, E-TFC) system of selection and device.

Background technology

It is further enhancing and the evolution of TD-SCDMA system at wireless portion that High Speed Uplink Packet inserts HSUPA, can improve uplink capacity and transmission rate greatly.

HSUPA has two kinds of data transmission manner: based on the scheduled transmission (ScheduledTransmission) of base station (NodeB) with based on radio network controller (Radio Network Controller, non-scheduled transmission RNC) (Non-Scheduled Transmission).In the existing HSUPA technology, the medium access control (Media Access Control, MAC) layer for Radio Link control (Radio Link Control, (Logical Channel LC), is used to carry the data of rlc layer RLC) to provide logic channel; (Transport Channel TrCH), is used to carry the data of MAC layer and physical layer is for the MAC layer provides transmission channel.

In order to support the HSUPA function, two kinds of new transmission channels have been introduced in the TD-SCDMA system: enhanced uplink dedicated channel (Enhanced uplink Delicated Channel, E-DCH) and up-enhancing control channel (E-DCH Uplink Control Channel, E-UCCH).E-DCH is used to carry the uplink business data of private subscribers; E-UCCH is used to carry up dedicated control signaling.

E-UCCH is mapped to identical enhancing uplink physical channel with E-DCH---E-PUCH (E-DCHPhysical Uplink Channel).Be private subscribers data channel E-DCH and the multiplexing E-PUCH channel of control channel E-UCCH associated therewith.The Transmission Time Interval of each E-DCH (TransmissionTime Interval, TTI) in, use one or more E-UCCH to carry the control information that up E-DCH business datum is associated.And being used for transmitting the Transmission Time Interval (time slot) of E-PUCH data accordingly, a user equipment (UE) sends data by an E-PUCH at most.

Simultaneously,, in an E-PUCH burst, can comprise E-UCCH and TPC instruction, also can not comprise according to configuring conditions such as E-UCCH number and the shared number of time slot of E-PUCH.If comprise E-UCCH in the E-PUCH burst, then the TPC instruction also sends together.

In above-mentioned existing HSUPA technology, UE realizes inserting E-DCH, and the process of carrying out transfer of data comprises:

(1) UE initiates E-DCH and inserts request by the E-RUCCH channel.

Insert in the request and carry upstream control signaling relevant and schedule information with inserting E-DCH.

UE no longer sends information by the E-RUCCH channel, until the HSUPA service ending after inserting the E-DCH success.

(2) after the base station receives the access request of UE transmission,, comprise some resources such as distributing power, code channel and time slot for UE distributes physical channel resources.And with the physical channel resources assignment information by E-AGCH channel notification UE.

HSUPA uses the E-AGCH channel as down physical channel, carries the physics signal channel resource allocation information, is specially the absolute grant control information of up E-DCH; Be used to realize fast dispatch based on NodeB, simultaneously also carrying be used for scheduling E-PUCH transmission power control (Transmitter Power Control, TPC) and synchronous shift (Synchronisation Shift SS) instructs.

(3) UE receives the physical source distributing information that the base station is returned.

UE receives and reads the physical source distributing information that the base station is returned from the E-AGCH channel.UE receives physical source distributing information by physical layer, and is given to the MAC layer.

(4) UE uses the physical resource transmission data of distributing.

Be that UE passes through E-DCH channel transmission data message, and transmit corresponding control information by E-UCCH.

At this moment, UE need carry out E-TFC earlier and select (specifically realizing at MAC), determine that (line data of going forward side by side distributes suitable MAC-e (MAC enhanced) protocol Data Unit for Protocol Data Unit, PDU) size, data could be passed through E-DCH channel transmission data after assembling.

(5) after the base station receives the data of UE transmission,, return ACK/NACK information and give UE according to result to the data verification.

The base station receives the data that UE transmits by the E-DCH channel, and passes through the phase related control information that the E-UCCH channel transmits, and cyclic redundancy check (CRC) (Cyclic RedundancyCheck, CRC) verification are carried out to the data that receive in the back.And the ack/nack of correspondence (ACK/NACK) information of replying is being sent to UE on corresponding E-HICH channel according to check results.

Wherein, verification by the time send ACK information, otherwise, send nack message.

(6) UE determines to send new data or retransmits the data that sent according to the ACK/NACK information that receives.

According to the ACK/NACK information of wherein carrying, upgrade the control information in the E-UCCH channel, be to send new data or data retransmission with decision.Be specially when receiving ACK, send new data; When receiving NACK, need data retransmission.

Wherein, after UE receives the physical resource information of distribution in the step (4), carry out the process that E-TFC selects, in existing protocol, do not provide concrete selection implementation method.Is very important and select suitable E-TFC to carry out transfer of data for the transfer of data between UE and the base station, may cause transmitting data decode failure even cause the system can't operate as normal if base station and UE can not determine suitable E-TFC.

For the mode of non-scheduled transmission, because it only is to provide the entity of absolute grant control information different for UE with the difference of scheduled transmission mode.In UE, be specially by radio resource the configuration of network side is decoded after, offer the MAC layer select so that the MAC layer carries out E-TFC, therefore have the problems referred to above equally.

Embodiment

The enhancing dedicated channel transport format collection system of selection that the embodiment of the invention provides is used for after UE receives the Entitlement Control Message of network side distribution, carries out E-TFC and selects.To realize that data allocations and assembling back send.Said method, the process and the E-TFC under the scheduled transmission mode that select for the E-TFC of non-scheduled transmission mode select all to be suitable for.Difference only is that the E-TFC selection needs the source difference of the Entitlement Control Message of use.

The enhancing dedicated channel transport format collection system of selection that the embodiment of the invention provides, its flow chart as shown in Figure 1, its execution in step is as follows:

Step S1: subscriber equipment is according to the Entitlement Control Message that network side distributes, calculate each E-TFC with each modulation system corresponding code rate.

At first, determine the total number of bits that the E-PUCH channel is carried under each modulation system according to Entitlement Control Message.

Then, calculate the merchant of total number of bits under the pairing transmission block of each E-TFC size and each modulation system respectively, obtain each E-TFC with each modulation system corresponding code rate.

Step S2: according to each E-TFC with each modulation system corresponding code rate and network side assigned radio resource configuration information, determine that the candidate E-TFC corresponding with each modulation system gathers.

Be specially according to the maximal rate λ that comprises in the wireless resource configuration _MaxWith minimum code rate λ _Min, determine in each E-TFC that aforementioned calculation goes out and each the modulation system corresponding code rate between described maximal rate λ _MaxWith minimum code rate λ _MinBetween code check, obtain the candidate E-TFC corresponding set with each modulation system.

Step S3: subscriber equipment is determined the maximum mandate transmitting power pairing code check corresponding with each modulation system that allow on the E-PUCH channel according to Entitlement Control Message and wireless resource configuration.

At every kind of modulation system:

According to the absolute grant value that comprises in the spreading factor of each modulation system that comprises in the code channel resource relevant information and the Entitlement Control Message, determine the maximum pairing gain factor of transmitting power of authorizing.

According to wireless resource configuration, determine the mapping relations between gain factor and the code check then; And according to the definite maximum pairing code check of transmitting power of authorizing of mapping relations.

Step S4: the subclass of determining candidate E-TFC set according to the pairing code check of determining of maximum mandate transmitting power corresponding with each modulation system is the E-TFC set corresponding with each modulation system.Specifically comprise:

The size of the pairing code check of each E-TFC and the corresponding pairing code check of maximum mandate transmitting power in the relatively more corresponding candidate E-TFC set with each modulation system.

Less than the E-TFC of the pairing code check of maximum mandate transmitting power of correspondence, form the E-TFC set corresponding by code check in the candidate E-TFC set with each modulation system.

Step S5: in each E-TFC corresponding set, select an E-TFC set that is used for transfer of data with each modulation system.Specifically comprise:

Gather all E-TFC that comprised at the E-TFC corresponding, according to the pairing transmission block size of each E-TFC with each modulation system.

And, determine the E-TFC set at the E-TFC place of corresponding maximum transmitted piece.

Then, the E-TFC set of selecting this correspondence the E-TFC place of maximum transmitted piece is used for transfer of data.

Step S6: adopt the E-TFC that selects to gather pairing modulation system encapsulation of data.

Describe a specific implementation flow process of the enhancing dedicated channel transport format collection system of selection that the embodiment of the invention provides in detail below by specific embodiment.As shown in Figure 2, comprise that step is as follows:

Step S10:UE obtains Entitlement Control Message and the wireless resource configuration that network side distributes.

UE obtains the mode of Entitlement Control Message (also we can say the physical channel resources assignment information), is inequality under scheduled transmission mode and non-scheduled transmission mode.

For the scheduled transmission mode, Entitlement Control Message is also referred to as the absolute grant control information.UE receives the absolute grant control information that the base station sends.Be specially: receive the absolute grant control information that network side (base station) issues from E-AGCH (E-DCH absolute grant channel).

Physical layer receives the absolute grant control information that transmits on E-AGCH, and absolute grant value, code channel resource relevant information, time interval resource relevant information, E-UCCH number indication relevant informations such as (ENI) that E-TFC is selected to need to use send to media access control layer.

For non-scheduling mode, UE receives corresponding Entitlement Control Message from RNC.Be specially: the RNC that radio resource receives network side is the Entitlement Control Message that UE distributes, and absolute grant value, code channel resource relevant information, time interval resource relevant information, E-UCCH number indication relevant informations such as (ENI) that E-TFC selects to need to use are handed to media access control layer.

Wherein, the following message that comprises in the above-mentioned Entitlement Control Message is specially:

1), absolute grant performance number: the indication base station allows the maximum transmission power of each subscriber equipment of E-PUCH channel, and the span of this performance number is 0dB～31dB, and the minimum interval is 1dB, specifically the Table 26 that saves referring to 4.10.1.1 among the 3GPPTS25.222.If the base station has been the E-PUCH the channel allocation interior a plurality of time slots of subframe, the then identical absolute grant performance number of each time slot employing.

2), (Code Resource Related Information, CRRI): the indication base station is spreading factor and the channel code that E-PUCH distributes to the code channel resource relevant information.In order to reduce complexity, each time slot adopts identical channel code during the multi-slot transmission.

3), (Timeslot Resource Related Information, TRRI): the indication base station is an E-PUCH distributed time slot resource to the time interval resource relevant information, represents the situation that takies of TS1～TS5 respectively with 5 bits.

4), E-UCCH number indication (E-UCCH Number Indicator, ENI).

When obtaining Entitlement Control Message, media access control layer also obtains the wireless resource configuration that radio resource obtains from the net side, for example: the configuration informations such as mapping below maximum permission code check, minimum permission code check, the different modulating mode between code check and the power gain factors.

Step S11: the Entitlement Control Message that user equipment (UE) receives, determine each available E-TFC with each modulation system corresponding code rate.

Pre-configured E-TFC tabulation in the user equipment (UE).When the Entitlement Control Message that receives network side, need carry out E-TFC when selecting, then calculate each E-TFC respectively according to the Entitlement Control Message that receives with each modulation system corresponding code rate, specifically comprise:

Determine the total number of bits that the E-PUCH channel is carried according to described Entitlement Control Message; Then, calculate the merchant of pairing transmission block size of each described E-TFC and described total number of bits respectively, obtain the code check of each E-TFC.That is to say: code check can calculate by following formula:

${\mathrm{\λ}}_e=\frac{S_e}{R_e}$

Wherein, S _eBe the pairing transmission block size of the E-TFC that is calculated;

R _eThe total number of bits of being carried for the E-PUCH channel.

Wherein, the total number of bits R that carried of E-PUCH channel _eCan obtain according to the code channel resource relevant information (CRRI) that comprises in the Entitlement Control Message that receives, time interval resource relevant information (TRRI), E-UCCH number indication relevant parameter information calculations such as (ENI).

According to the code channel resource relevant information (CRRI) that comprises in the Entitlement Control Message, time interval resource relevant information (TRRI), can convert out total number of bits entrained in the E-DCH signaling, deduct the shared bit number of band inner control signaling with this total number of bits, obtain R _eValue.Wherein, the shared bit number of band inner control signaling comprises: the bit number that the E-UCCH number is indicated, the TPC instruction is shared etc.R then _eCan calculate by following formula:

$R_e=\frac{(A_1\×\mathrm{TS}\_\mathrm{Number})}{\mathrm{SF}}-(\mathrm{ENI}+1)\×A_2$

Wherein, A ₁, A ₂Be the constant relevant with modulation system;

TS_Number is the shared timeslot number of uplink transport channel (being included in the time interval resource relevant information);

SF is spreading factor (being included in the code channel resource relevant information);

ENI is the indication of E-UCCH number.

Modulation system generally can comprise Quaternary Phase Shift Keying, and (Quaternary Phase Shift Keying is QPSK) with two kinds of modulation systems of 16 ary quadrature amplitude (16QAM).Above-mentioned spreading factor SF is also relevant with modulation system.

Under two kinds of modulation systems of QPSK and 16QAM, R _eWith the conversion corresponding relation of Entitlement Control Message specifically can be shown in following table 1.

Table 1

Step S12: according to the wireless resource configuration that receives and each E-TFC with each modulation system corresponding code rate, determine that the candidate E-TFC corresponding with each modulation system gathers.

According to the maximal rate λ that comprises in the wireless resource configuration _MaxWith minimum code rate λ _Min, and aforementioned calculation each E-TFC and each the modulation system corresponding code rate that go out, determine the candidate E-TFC set corresponding with each modulation system.The code check of each E-TFC in wherein corresponding with each modulation system candidate E-TFC set is all between the maximal rate and minimum code rate of network side configuration.

For example: two kinds of modulation systems of QPSK and 16QAM at after above-mentioned deterministic process, can obtain the candidate E-TFC set C corresponding with the QPSK modulation system ₁Gather C with 1 with 6QAM modulation system candidate E-TFC ₂The pairing code check of E-TFC in two set all satisfies ${\mathrm{\&lambda;}}_{\min }\&le;\frac{S_e}{R_e}<{\mathrm{\&lambda;}}_{\max },$ Also we can say the pairing transmission block size of the E-TFC (S in two set _eBe TB-Size) all satisfy λ _Min* R _e≤ S _e＜λ _Max* R _eNeed to prove that the transmission block size of being calculated must drop in the scope of transmission block size of E-TFC form defined.

Annotate: each E-TFC is inequality at the code check that QPSK and two kinds of modulation systems of 16QAM calculate, therefore when determine candidate E-TFC set with maximal rate and minimum code rate after, the E-TFC that comprises during the candidate E-TFC under two kinds of modulation systems gathers is likely inequality.Because the candidate E-TFC that determines set will be used for network side distributed time slot and code channel resource, therefore, information such as the time slot that uses during aforementioned calculation and code channel must and the Entitlement Control Message of distribution in consistent.

Above-mentioned is that example describes with the scheduling mode, for non-scheduled transmission mode, selects E-TFC set C ₁And C ₂Definite process and scheduling mode similar, just its Entitlement Control Message by high-level signaling (for example: RB_SETUP message) specify, repeat no more herein is.

Step S13: subscriber equipment is determined the maximum mandate transmitting power pairing code check corresponding with each modulation system that allow on the E-PUCH channel according to Entitlement Control Message and wireless resource configuration.Specifically comprise:

At first, according to spreading factor in the code channel resource relevant information that comprises in the Entitlement Control Message and absolute grant value, determine the pairing gain factor of maximum mandate transmitting power on the E-PUCH channel.

Then, according to according to described wireless resource configuration, determine the mapping relations between gain factor and the code check; And determine the pairing code check of maximum mandate transmitting power on the E-PUCH channel according to these mapping relations.

Wherein, the pairing code check of maximum mandate transmitting power at QPSK and 16QAM modulation system calculates respectively, and its computational process is identical, and is just different at different modulation system parameters.

Discuss (referring to the flow process of following Fig. 3) below the specific implementation process more in detail

Step S14:, determine that the subclass of candidate E-TFC set is the E-TFC set corresponding with each modulation system according to the pairing code check of determining of maximum mandate transmitting power corresponding with each modulation system.

Pin different modulating mode has been determined the pairing code check λ of maximum mandate transmitting power _{E, max}After, according to λ _{E, max}Further the candidate E-TFC set of determining corresponding with each modulation system retrained; Promptly authorize the pairing code check of transmitting power at the candidate E-TFC set and the maximum of every kind of modulation system:

The size of the pairing code check of maximum mandate transmitting power of the pairing code check of each E-TFC and this modulation system correspondence during relatively the candidate E-TFC of this modulation system correspondence gathers.And

Less than the E-TFC of the pairing code check of maximum mandate transmitting power, form the E-TFC set corresponding by code check in the candidate E-TFC set with this modulation system.

That is to say: in the E-TFC set of each modulation system correspondence of determining, the code check of each E-TFC all satisfies

We can say that also in the E-TFC set of each modulation system correspondence of determining, the pairing transmission block size of each E-TFC all satisfies λ _Min* R _e≤ S _e＜λ _{E, max}* R _e

For example: at the candidate E-TFC set C corresponding with the QPSK modulation system ₁With 16QAM modulation system candidate E-TFC set C ₂, further after the constraint, obtain the pairing E-TFC set of QPSK modulation system D ₁With the pairing E-TFC set of 16QAM modulation system D ₂Wherein, E-TFC set D ₁With E-TFC set D ₂Be respectively candidate E-TFC set C ₁With candidate E-TFC set C ₂Subclass.

Step S15: in the E-TFC set corresponding, select an E-TFC set that is used for transfer of data with each modulation system.

Gather all E-TFC that comprised at the E-TFC corresponding with each modulation system, according to the pairing transmission block size of each E-TFC, determine the E-TFC set at the E-TFC place of corresponding maximum transmitted piece, the E-TFC set of selecting this correspondence the E-TFC place of maximum transmitted piece is used for transfer of data.

When if the E-TFC at the E-TFC place of corresponding maximum transmitted piece gathers more than one,, determine that the pairing E-TFC set of modulation system that wherein a transmitting power is minimum gathers for being used for transfer of data E-TFC then according to the needed transmitting power of each modulation system.

For example: at the pairing E-TFC set of the QPSK modulation system of determining D ₁With the pairing E-TFC set of 16QAM modulation system D ₂, compare D ₁And D ₂In the pairing transmission block size of each E-TFC:

If the E-TFC of corresponding maximum transmitted piece only belongs to set D ₁, then select set D ₁For being used for transfer of data E-TFC set;

If the E-TFC of corresponding maximum transmitted piece only belongs to set D ₂, then select set D ₂For being used for transfer of data E-TFC set;

If the E-TFC of corresponding maximum transmitted piece belongs to set D simultaneously ₁And D ₂, then according to set D ₁And D ₂The needed transmitting power of pairing modulation system selects a little set of then required transmitting power for being used for transfer of data E-TFC set.For example:, then select the set D corresponding with the 16QAM modulation system if adopt the required transmitting power of 16QAM modulation system low ₂, otherwise with select the corresponding set D of QPSK modulation system ₁, be used for transfer of data.

That is to say, preferable, when UE selects the E-TFC set, should select the pairing E-TFC set of the modulation system that needs low PE-PUCH (E-PUCH transmitting power) as much as possible for use.

Step S16: adopt the E-TFC that selects to gather pairing modulation system encapsulation of data.

For example: at QPSK and two kinds of modulation systems of 16QAM, when the set of selecting that is used for transfer of data is set D ₁The time, select set D ₁Pairing QPSK modulation system encapsulation of data; When the set of selecting that is used for transfer of data is set D ₂The time, then select set D ₂Pairing 16QAM modulation system encapsulation of data.

That is to say that the employed transmission block size of UE encapsulation upstream data should not exceed the scope of the pairing transmission block size of each E-TFC that comprises in the selected E-TFC set.Also effectively guaranteed that the pairing code check of the employed E-TFC of UE is between the maximal rate and minimum code rate of network side configuration this moment, thereby make that employed code check all is effectively to various modulation systems such as QPSK and 16QAM, the principle of protocol compliant defined.

Preferable, the UE encapsulation of data and send packaged data after, if receive the successful acknowledge message of network side, then continue to send new data; If receive the not successful acknowledge message of network side, then need data retransmission, must adopt the E-TFC encapsulation of data identical with the employed E-TFC of former data this moment.That is to say when being in the re-transmission state to have only with initial transmission to be in status of support with the E-TFC that transmits block size.

Preferable, at step S16: adopt before the E-TFC that selects gathers pairing modulation system encapsulation of data, can also comprise:

Step S17:, determine the step of the logical channel set of data to be sent according to the scheduling type of current transmission time interval.Then among the step S16, adopt the E-TFC that selects to gather pairing modulation system, the data to be sent in the logical channel set of the described data to be sent determined are encapsulated.

The step of being somebody's turn to do the logical channel set of determining data to be sent only needs carry out before step S16 carries out and gets final product, for example, can before step S10, just be finished, or after step S10, just carry out, also can be after step S15, or middle random time is carried out.

Above-mentioned steps S13, the subclass of determining candidate E-TFC set according to the pairing code check of determining of maximum mandate transmitting power for the specific implementation flow process of the E-TFC set corresponding with each modulation system as shown in Figure 3, comprise the following steps:

Step S131:, determine the pairing gain factor of maximum mandate transmitting power on the E-PUCH channel according to spreading factor that comprises in the described code channel resource relevant information and absolute grant value.

Generally, the E-PUCH channel transmitting power can be calculated by following formula:

P _E-PUCH＝P _e-base+L+β _e

Wherein, P _E-baseBe a closed power value of safeguarding between UE and the base station;

L is a path loss, generally can obtain by the monitoring of physical channel is measured;

β _eBe the gain factor of E-PUCH channel, with E-PUCH physical resource (Entitlement Control Message), the modulation system of distributing and to mix automatic repeat requests (HARQ) power excursion relevant.

Above-mentioned P _E-baseBy network side configuration, all can increase or reduce the certain numerical value Δ after receiving the TPC order that network side sends at every turn _E-baseFor example: after " up " order of receiving TPC, P _E-baseOn the basis of original numerical value, increase Δ _E-baseAfter " down " order of receiving TPC, P _E-baseOn the basis of original numerical value, reduce Δ _E-baseΔ _E-baseThe size of value is disposed by high level.Generally under the scheduled transmission mode, the TPC order is transmitted by the E-AGCH channel; Under non-scheduled transmission mode, the TPC order is transmitted by the E-HICH channel.

Usually, work as β _e=P ₀+ α _eThe time, the transmitting power of E-PUCH reaches the maximum transmitting power of authorizing; Wherein, p ₀Be the absolute grant value that comprises in the Entitlement Control Message, i.e. the E-AGCH channel absolute grant performance number of being carried; α _eGain factor for corresponding E-PUCH spreading factor.

And α _eAnd there is corresponding relation as shown in table 2 below between the spreading factor SF that E-PUCH adopted.

That is to say that the pairing gain factor of maximum mandate transmitting power of E-PUCH channel is: β _e=P ₀+ α _e, i.e. β _{E, max}

Step S132:, determine the mapping relations between gain factor and the code check according to wireless resource configuration.Specifically comprise:

, comprise in the wireless resource configuration with reference to code check according to a group of network side appointment with reference to the mapping table between code check and the reference power, the gain factor of corresponding E-PUCH spreading factor _eWith the power offset values that mixes automatic repeat requests (HARQ), determine the mapping relations between gain factor and the code check.

Comprise in the wireless resource configuration one in the transmission the reference code check and the corresponding relation mapping table of relative reference power, promptly comprise a mapping table of one group of reference point.Each that can search E-DCH by this mapping table is with reference to the pairing relative reference power of code check.Wherein to a corresponding mapping table all being arranged with every kind of modulation system.Generally, this mapping table can be included in the E-TFCS information of RB SETUP message.

One group of maximum λ according to the appointment of network side appointment with reference to code check λ _MaxWith minimum value λ _Min(relevant with modulation system) determines given λ _eThe lower limit λ of a minimum interval ₀With upper limit λ ₁, λ then ₀And λ ₁Can determine by following manner:

(1) if λ _Min≤ λ _e＜λ _Max, then:

In one group of above-mentioned appointment all code check values that comprise with reference to code check λ, satisfy λ≤λ _eThe code check maximum of relation is designated as λ ₀And

In one group of above-mentioned appointment all code check values that comprise with reference to code check λ, satisfy λ＞λ _eThe code check minimum value of relation is designated as λ ₁
