Description

A kind of sending method of semi-static enhancing dedicated channel physical uplink channel

Technical field

The present invention relates to the data transmission technology in the TD-SCDMA system; Particularly relate to high speed uplink packet and insert semi-persistent scheduling in (HSUPA) (Semi-Persistent Scheduling, SPS) sending method of enhancing dedicated channel physical uplink channel (E-PUCH).

Background technology

In the TD-SCDMA system, subscriber equipment (UE) confirms according to the uplink service speed of UE application whether the uplink service of this UE transmits through HSUPA by radio network controller (RNC) when inserting.When RNC confirms: the uplink service of a UE is during through the HSUPA transmission, and RNC also needs further to confirm: the uplink service of this UE is still to transmit through scheduling E-PUCH through non-scheduling E-PUCH transmission, semi-persistent scheduling E-PUCH (this paper abbreviates semi-static E-PUCH as) transmission among the HSUPA.When RNC confirms the uplink service of a UE is when transmitting through non-scheduling E-PUCH, semi-static E-PUCH or scheduling E-PUCH, and RNC is informing base station (NODEB) and UE simultaneously: the uplink service of this UE through above-mentioned which kind of E-PUCH transmits.

When the RNC decision is transmitted the uplink service of UE through non-scheduling E-PUCH; RNC can dispose non-scheduling E-PUCH to UE, and will dispose to the number of power authorization message, nodal information, gap information and the enhancing dedicated channel ascending control channel (E-UCCH) of the frame branch multiplexing parameters of the non-scheduling E-PUCH of UE and non-scheduling E-PUCH and notify simultaneously to NODEB and UE.Configuration is monopolized for the non-scheduling E-PUCH of UE by UE.Even UE does not have uplink business data to need transmission, distribute to the non-scheduling E-PUCH of this UE and can not be used by other UE.

When RNC notifies NODEB and UE to transmit the uplink service of UE through semi-static E-PUCH, NODEB will dispose semi-static E-PUCH for UE.Each HSUPA carrier wave of each sub-district of NODEB all has a scheduler.For the UE of any needs on any HSUPA carrier wave in the sub-district through semi-static E-PUCH transmission uplink service; Scheduler on this carrier wave of this sub-district will dispose semi-static E-PUCH for this UE according to the schedule information (SI) of this UE, and will dispose to all parameters of the semi-static E-PUCH of this UE and notify this UE.The semi-static E-PUCH of UE is given in configuration in case UE is given in configuration, is just monopolized by UE.But NODEB is the semi-static E-PUCH of reprovision UE at any time.When NODEB finds that the E-PUCH of bigger variation or UE takes place for certain or some items of information among the SI of UE receptivity does not satisfy block error rate (BLER) demand, the semi-static E-PUCH that NODEB can reprovision UE.The SI of UE comprises following item of information:

(1) TEBS: always strengthen dedicated channel (E-DCH) memory state, be used to represent the E-DCH total amount of data of UE;

(2) HLBS: high priority logic channel memory state is used to represent the data volume of the high priority logic channel of UE;

(3) HLID: high priority Logic Channel Identifier (ID);

(4) UPH:UE power headroom, the power mandate that is used to calculate semi-static E-PUCH, the channel quality of UPH reflection UE;

(5) SNPL: Serving cell and adjacent sub-district path loss ratio are used to calculate the power of the interference that UE causes adjacent sub-district

In the above-mentioned item of information, first three item of information will reflect the upstream traffic of UE, and latter two item of information will reflect the wireless channel situation of UE.

When the semi-static E-PUCH of NODEB reprovision UE, UE will discharge the semi-static E-PUCH that has disposed to it, accept the NODEB reprovision and will give its semi-static E-PUCH, and give on its semi-static E-PUCH at reprovision and to transmit uplink service.The configuration of semi-static E-PUCH and reprovision parameter comprise: cycle P and the length L of semi-static E-PUCH, the number of power authorization message, nodal information, gap information and the E-UCCH of semi-static E-PUCH etc.

When uplink service through scheduling E-PUCH transmission UE of RNC notice NODEB and UE, the scheduler on each HSUPA carrier wave of interior each sub-district of NODEB will need once be dispatched through the UE that scheduling E-PUCH is transmitted uplink service on this carrier wave all in each subframe.Through scheduling, the UE that selection is scheduled, and be each UE allocation schedule E-PUCH that is scheduled.NODEB will distribute to all parameter notice UE of the scheduling E-PUCH of UE.UE can only transmit uplink service through scheduling E-PUCH in the occupied subframe of the scheduling E-PUCH of distributing to it.Usually, when each subframe UE was scheduled, duration of scheduling E-PUCH of distributing to it was shorter.The configuration parameter of scheduling E-PUCH comprises: interval, the power authorization message at each scheduling E-PUCH subframe scheduling E-PUCH, nodal information, gap information and E-UCCH number etc. between the duration of scheduling E-PUCH, adjacent two the scheduling E-PUCH subframes.

More non-scheduling E-PUCH, semi-static E-PUCH and scheduling E-PUCH can obtain as drawing a conclusion:

See from the configuration mode of E-PUCH (1) in a single day RNC disposes non-scheduling E-PUCH to UE, the configuration parameter of this non-scheduling E-PUCH just immobilizes.The configuration parameter of non-scheduling E-PUCH can not change with the variation of the wireless channel of the upstream traffic of UE and UE adaptively, and therefore, the resource utilization of non-scheduling E-PUCH and spectrum efficiency are all very low.Semi-static E-PUCH and scheduling E-PUCH are disposed to UE by NODEB; NODEB will adjust the configuration parameter of semi-static E-PUCH and scheduling E-PUCH adaptively along with the variation of the variation of the upstream traffic of UE and UE wireless channel; Therefore, the resource utilization of semi-static E-PUCH and scheduling E-PUCH and spectrum efficiency all are higher than non-scheduling E-PUCH.

(2) from the propagation delay time angle of E-PUCH, for the responsive business of delay requirement, non-scheduling E-PUCH and semi-static E-PUCH can guarantee professional delay requirement, but scheduling E-PUCH is difficult to guarantee the delay requirement of UE business.

In sum, take all factors into consideration resource utilization, spectrum efficiency, to the adaptability of UE wireless channel with to the professional factors such as support of delay sensitive, semi-static E-PUCH is superior to other two kinds of E-PUCH.

The above-mentioned advantage of semi-static E-PUCH just, it will replace non-scheduling E-PUCH is that UE provides stable uplink service speed with higher spectrum efficiency and less time delay.But the receptivity of semi-static E-PUCH awaits improving.The present invention studies the sending method of semi-static E-PUCH in the hope of improving the receptivity of semi-static E-PUCH.Be presented in the sending method of semi-static E-PUCH the 3GPP standard below in detail from the following aspects.

(1) configuration of semi-static E-PUCH;

(2) generation of semi-static E-PUCH signal comprises: the coding of E-DCH data block, modulation and multiplexing, the coding of E-UCCH, QPSK (QPSK) modulation and multiplexing, the spread spectrum of E-PUCH and scrambling;

The feedback method of (3) affirmation of semi-static E-PUCH/non-affirmation (ACK/NACK) information

(4) uplink power control of semi-static E-PUCH (ULPC) method comprises: the method that the ULPC of the E-PUCH that carries to the method for UE and the relevant down channel of UE response orders is carried in the ULPC order of each E-PUCH subframe that NODEB generates;

(5) uplink synchronous of semi-static E-PUCH control (ULSC) method comprises: the method that the ULSC of the E-PUCH that carries to the method for UE and the relevant down channel of UE response orders is carried in the ULSC order of each E-PUCH subframe that NODEB generates;

When the uplink service of UE transmitted through semi-static E-PUCH, NODEB was responsible for disposing semi-static E-PUCH to UE.NODEB can specify the cycle P of semi-static E-PUCH and the number of the interior E-UCCH of length L, power authorization message (PRRI), nodal information (CRRI), gap information (TRRI) and each E-PUCH subframe etc. when disposing semi-static E-PUCH to UE.NODEB can send to UE with the parameter of these semi-static E-PUCH.UE can confirm according to cycle P and length L: the L sub-frame that in each length equals the cycle of P sub-frame, begins most is to distribute to the occupied subframe of semi-static E-PUCH of this UE.In each distributed to the semi-static E-PUCH subframe of UE, power mandate, node and the time slot that semi-static E-PUCH adopts confirmed by parameters such as PRRI, CRRI and TRRI respectively.Here, require emphasis and point out: distributing to each semi-static E-PUCH subframe of UE, NODEB disposes semi-static E-PUCH to UE and has identical power mandate, identical node and identical gap information.After NODEB disposed semi-static E-PUCH to UE, this semi-static E-PUCH was just monopolized by this UE.Only if the semi-static E-PUCH of NODEB decision reprovision UE, otherwise this semi-static E-PUCH just belongs to this UE forever.When the semi-static E-PUCH of NODEB reprovision UE, UE will discharge the semi-static E-PUCH that has disposed to it, accept the NODEB reprovision and will give its semi-static E-PUCH, and give on its semi-static E-PUCH at reprovision and to transmit uplink service.Reprovision still is made up of for the configuration parameter of the semi-static E-PUCH of UE cycle P and the parameters such as length L, PRRI, CRRI, TRRI and E-UCCH number of semi-static E-PUCH.In each subframe that reprovision is given its semi-static E-PUCH place, E-PUCH has specified power mandate, node and time slot by PRRI, CRRI and TRRI.

In each subframe that the semi-static E-PUCH place of UE is given in configuration, UE is mapped to the uplink business data that carries on the MAC-d stream on the E-DCH.In each semi-static E-PUCH subframe, UE generates an E-DCH data block for power mandate, node and the time slot of its semi-static E-PUCH according to configuration.Then, this E-DCH data block is encoded, and the bit stream that coding obtains is modulated into a symbols streams, this symbols streams is multiplexed on the semi-static E-PUCH of this subframe.

UE also is used for generation 10 information bits of the E-DCH data block decoding of this subframe; These 10 information bits comprise: the E-DCH data block length subscript of 6 bits, the mixed automatic retransmission request process sign (HARQ ID) of 2 bits and the retransmission sequence number (RSN) of 2 bits.These 10 information bits are that E-UCCH goes up data carried by data.Last 10 information bits of E-UCCH are through coding and QPSK modulation, and generation length is 16 E-UCCH symbols streams, and this symbols streams will be multiplexed on the semi-static E-PUCH of this subframe.

In each semi-static E-PUCH subframe, transmitting power control (TPC) symbol that is multiplexed on the semi-static E-PUCH of this subframe can be selected arbitrarily in four QPSK modulation symbols.

The symbols streams that is multiplexed on the semi-static E-PUCH of this subframe is sent to NODEB through spread spectrum, scrambling and a series of radio frequency processing with certain power and regular hour lead (TA).

Particularly, the generation method of semi-static E-PUCH signal comprises the steps in the 3GPP standard.

Step 1:UE disposes cycle P and length L to its semi-static E-PUCH according to NODEB, and UE can confirm to distribute to the subframe number of its semi-static E-PUCH; Dispose PRRI, CRRI and TRRI to its semi-static E-PUCH according to NODEB, UE can know power mandate, node and the time slot of configuration to its semi-static E-PUCH.In any sub-frame " m " that its semi-static E-PUCH place is given in configuration, UE will be n according to power mandate, node and length of time slot assembling of semi-static E-PUCH _aE-DCH data block a (m) (m, n), n=1,2 ..., n _aAnd confirm the modulation system of this data block (m).The method of specified data block length and modulation system sees also relevant 3GPP standard, repeats no more here.

Step 2: to this data block a (m n) encodes, and obtains with bit sequence b (m)=b (m, 1) b (m, 2) ... b (m, n) ... b (m, n _b(m)-1) b (m, n _b(m)).n _b(m) length of the later bit sequence of presentation code.According to the modulation system of this definite data block of step 1, bit sequence b (m n) modulates, generation symbol sebolic addressing s (m, n), n=1,2 ..., n _s(m), n _s(m) length of expression symbol sebolic addressing.

In practical application, those skilled in the art often adopt b (m, n), n=1,2 ..., n _b(m) mode is represented bit sequence b (m)=b (m, 1) b (m, 2) ... and b (m, n) ... b (m, n _b(m)-1) b (m, n _b(m)), this paper will unify to adopt this mode that one bit sequence is described.

Step 3: generation is used for data block a (m, n) the information a of decoding _E-UCCH(m, n), n=1,2 ..., 10, this information comprises: the RSN of the HARQ ID of the data block length subscript of representing with 6 bits, the data block represented with 2 bits and the data block represented with 2 bits.This information is that E-UCCH goes up data carried by data.

Step 4: E-UCCH is gone up data carried by data a _E-UCCH(m n) encodes and QPSK modulates.Use b _E-UCCH(m, n), n=1,2 ..., 32 expressions are to a _E-UCCH(length of this bit sequence is 32 for m, the bit sequence of n) encoding and obtaining; Use s _E-UCCH(m, n), n=1,2 ..., 16 expressions are to b _E-UCCH(m n) carries out the QPSK modulation and obtains symbol sebolic addressing, and the length of this symbol sebolic addressing is 16.

Step 5: with symbol sebolic addressing s (m, n), symbol sebolic addressing s _E-UCCH(m n) is multiplexed on the E-PUCH of m subframe with the TPC symbol.Multiplexing concrete grammar sees also relevant 3GPP standard.The TPC symbol that is multiplexed on the E-PUCH can be selected arbitrarily in four QPSK modulation symbols.

Step 6: the symbol sebolic addressing to being multiplexed on the E-PUCH carries out spread spectrum and scrambling.

Step 7: send to NODEB through the signal of spread spectrum and the scrambling radio frequency through UE what m subframe UE carried on E-PUCH.

In the sending method of above-mentioned semi-static E-PUCH, the length of last each TTI of E-PUCH is fixed as the sub-frame of 5ms, sends a data block at each subframe E-PUCH, and interweaving of the last data block of E-PUCH is intra-frame interleaving.UE sends L E-DCH data block through the L sub-frame of distributing to it in cycle P.

The ACK/NACK information of each data block feeds back to UE through the E-HICH with semi-static E-PUCH pairing.Feedback method is following particularly:

When RNC transmits through semi-static E-PUCH at the uplink service of notice NODEB and UE:UE, can dispose a signature sequence group on an E-HICH and this E-HICH to UE.RNC can notify NODEB and UE simultaneously: the ID and the group number of configuration to the signature sequence group of UE of the E-HICH of UE given in configuration.This signature sequence group comprises four signature sequences that logic ID is continuous.Wherein, the former sequence of first signature sequence and antitone sequence are respectively applied for feedback nack message and ACK information.As NODEB during to E-DCH data block decoding error, NODEB will feed back nack message and give UE; When NODEB deciphers when correct the E-DCH data block, NODEB gives UE with feeding back ACK information.When NODEB feedback nack message, NODEB feeds back to UE through corresponding E-HICH with the former sequence of first signature sequence in the corresponding signature sequence group; When NODEB feeding back ACK information, NODEB feeds back to UE through corresponding E-HICH with the antitone sequence of first signature sequence in the corresponding signature sequence group.

NODEB will confirm E-PUCH and and the E-HICH of this E-PUCH pairing between timing parameters n _E-HICHThe definition of this parameter sees also relevant 3GPP standard.NODEB can send to RNC with this parameter, and RNC can be transmitted to UE with this parameter.Therefore, NODEB and UE will keep identical E-PUCH and the timing relationship between the E-HICH, that is: UE send to the ACK/NACK information of the E-DCH data block of carrying on the semi-static E-PUCH of NODEB in the m subframe will be at m+d _E-HICHSubframe feeds back to UE through antitone sequence/former sequence that the E-HICH with this semi-static E-PUCH pairing goes up corresponding signature sequence.Here, d _E-HICHExpression is by n _E-HICHThe E-PUCH of decision and the timing difference between the E-HICH, unit is: subframe.

Introduce ULPC method and the ULSC method of the semi-static E-PUCH of UE below.

The ULPC that the semi-static E-PUCH of UE and scheduling E-PUCH are united based on GAP.Scheduling interval (GAP) is the parameter of the ULPC of E-PUCH, and this values of parameters is disposed to NODEB and UE by RNC simultaneously.Each semi-static E-PUCH subframe all is regarded as an E-PUCH subframe by NODEB with each scheduling E-PUCH subframe.The transmitting power of first E-PUCH subframe confirms that through open-loop power control method the transmitting power of each E-PUCH subframe progressively gets into closed power control later on, adjusts according to the ULPC order of the E-PUCH that feeds back from relevant down channel.If the ULPC that UE receives order is " UP ", UE just improves a step-length with the transmitting power of E-PUCH; If the ULPC that UE receives order is " DOWN ", UE just reduces a step-length with the transmitting power of E-PUCH.The ULPC step-length of this E-PUCH is disposed to NODEB and UE by RNC simultaneously.

When the transmission that E-PUCH occurs at interval the time, if blanking time less than GAP, then at interval after first E-PUCH subframe adopt close-loop power controlling method to confirm transmitting power; If be not less than GAP blanking time, then first E-PUCH subframe adopts open-loop power control method to confirm transmitting power after the interval.

Timing Advance (TA) when each E-PUCH subframe is sent is confirmed through the ULSC method.The TA of first E-PUCH subframe adopts the TA of a nearest up channel to send; After first E-PUCH subframe, the E-PUCH of UE gets into closed loop ULSC.UE orders the TA of adjustment E-PUCH according to the ULSC from relevant down channel feedback: if the ULSC that UE receives order is " UP ", then UE adjusts a step-length forward with TA; If the ULSC that UE receives order is " DOWN ", then UE adjusts a step-length backward with TA; If the ULSC that UE receives order is " DO NOTING ", then UE will not adjust TA.The step-length of the ULSC of this E-PUCH is disposed to NODEB and UE by RNC simultaneously.

Above-mentionedly be used to feed back the ULPC order of E-PUCH and the relevant down channel of ULSC order is: with the E-HICH of semi-static E-PUCH pairing and the scheduling E-AGCH that matches with scheduling E-PUCH.These two down channels join together to feed back ULPC order and the ULSC order that each E-PUCH subframe generates.

In each E-PUCH subframe, NODEB generates a ULPC order and a ULSC order according to the reception signal at this subframe E-PUCH.NODEB carries the ULPC&ULSC order of the E-PUCH that generates to the method for UE following:

Join together to feed back the ULPC&ULSC order of E-PUCH of this UE of the up-to-date generation of NODEB with the E-HICH of semi-static E-PUCH pairing with the E-AGCH of scheduling E-PUCH pairing.

According to timing relationship, the ULPC&ULSC order that generates according to the reception signal of the E-PUCH of m subframe feeds back to UE through the E-HICH or the E-AGCH of m+d subframe.Here, d representes that NODEB generates ULPC/ULSC and orders the needed processing time.If in the m+d subframe, this UE both not with the E-HICH of semi-static E-PUCH pairing, also not with the E-AGCH of scheduling E-PUCH pairing, then can't carry to UE in the ULPC&ULSC order that the m subframe generates.This ULPC&ULSC order will be preserved, and is carried to UE through E-HICH or E-AGCH up to this ULPC&ULSC order, and perhaps this ULPC&ULSC order is replaced by newly-generated ULPC&ULSC order.

When in the m+d subframe, the E-HICH of the existing and semi-static E-PUCH pairing of this UE also has the E-AGCH with the scheduling E-PUCH pairing, and then E-HICH and E-AGCH order carrying the ULPC&ULSC that the m subframe generates simultaneously.

When in the m+d subframe, this UE has only the E-HICH with semi-static E-PUCH pairing, perhaps has only the E-AGCH with the scheduling E-PUCH pairing, and then the ULPC&ULSC order that generates of m subframe will be carried to UE through E-HICH or E-AGCH.

Following with the method for the ULPC&ULSC order of the E-PUCH of the E-HICH feedback UE of semi-static E-PUCH pairing:

RNC distributes a signature sequence group on an E-HICH and this E-HICH for the UE that each has semi-static E-PUCH.This signature sequence group comprises four signature sequences that logic ID is continuous.According to the 3GPP standard, NODEB feeds back six kinds of combinations of ULPC&ULSC order respectively through six sequences of the antitone sequence formation of back three sequences in this signature sequence group and these three sequences.The ULPC order has two kinds: UP and DOWN.The ULSC order has three kinds: UP, DOWN and DO NOTING.ULPC and ULSC order have six kinds of combinations altogether.These six ULPC&ULSC command in combination and six sequences are corresponding one by one.Concrete corresponded manner sees also the 3GPP standard.

Following with the method for the ULPC&ULSC order of the E-PUCH of the E-AGCH feedback UE of scheduling E-PUCH pairing:

Last TPC territory and the SS territory of existing of E-AGCH, the ULPC order and the ULSC that are respectively applied for feedback E-PUCH order.

UE is from extracting the ULPC&ULSC order with the E-HICH of semi-static E-PUCH pairing with the E-AGCH of scheduling E-PUCH pairing, based on transmitting power and the Timing Advance of the definite E-PUCH of ULPC&ULSC order that extracts.

Particularly, establish UE and be " UP " in the m+d subframe from the ULPC order that E-HICH or E-AGCH extract, then UE improves a step-length with the E-PUCH transmitting power when the E-PUCH of emission m+d+d1 subframe; If UE is " DOWN " in the m+d subframe from the ULPC order that E-HICH or E-AGCH extract, then UE reduces a step-length with the E-PUCH transmitting power when the E-PUCH of emission m+d+d1 subframe.Here, d1 representes that UE extracts and response ULPC orders the needed time.Unit is: subframe.

When UE is " UP " in the m+d subframe from the ULSC order that E-HICH or E-AGCH extract, then UE puies forward previous step-length with the E-PUCH Timing Advance when the E-PUCH of emission m+d+d1 subframe; If UE is " DOWN " in the m+d subframe from the ULSC order that E-HICH or E-AGCH extract, then UE postpones a step-length with the Timing Advance of E-PUCH when the E-PUCH of emission m+d+d1 subframe; If UE is " DO NOTING " in the m+d subframe from the ULSC order that E-HICH or E-AGCH extract, then UE remains unchanged the Timing Advance of E-PUCH when the E-PUCH of emission m+d+d1 subframe.

Only adopt intra-frame interleaving in the sending method of above-mentioned semi-static E-PUCH, and intra-frame interleaving is limited to the lifting of E-PUCH decoding performance.Therefore, the sending method of existing semi-static E-PUCH will cause the receptivity of semi-static E-PUCH not ideal enough.

Embodiment

For making the object of the invention, technical scheme and advantage clearer, the present invention is done to describe in detail further below in conjunction with accompanying drawing and specific embodiment.

In practical application,,, be very limited to the lifting of the decoding performance of this data block if having only intra-frame interleaving in the transmission of this data block for a data block to be sent.If adopt interframe to interweave in the transmission of this data block, just can further promote the decoding performance of this data block.The gain that interweaves of darker its interframe of the interframe interleave depth of this data block is just big more.

Based on this, main thought of the present invention is: in the configuration of semi-static E-PUCH, the transmission time interval (TTI) of semi-static E-PUCH by a sub-frame that is fixed as 5ms, is become configurable N _TTISub-frame.When the semi-static E-PUCH of NODEB configuration or reprovision UE, NODEB can select to dispose to the cycle P of the semi-static E-PUCH of UE, the length N of TTI _TTI, distribute to number L and the interval of adjacent two TTI of the TTI of UE in each cycle P.Like this, for each TTI, during the E-PUCH signal that in needs generate this TTI, sends, need to realize N _TTIThe interframe of sub-frame data interweaves, thereby the gain that interweaves that can utilize interframe to interweave to be produced promotes the receptivity of semi-static E-PUCH.

In addition, because the introducing that interweaves of interframe, the transmitting time length of semi-static E-PUCH is expanded to the N in the cycle P by the L sub-frame in the cycle P _TTI* L sub-frame.Like this, when carrying out the control of uplink power control and uplink synchronous, can the ULPC of semi-static E-PUCH and the frequency of ULSC be increased (N _TTI-1) doubly.Correspondingly, the performance of the ULPC of semi-static E-PUCH and ULSC will improve.Therefore, the uplink power control that introducing brought that interweaves through interframe and the lifting of uplink synchronous control performance can also further promote the receptivity of semi-static E-PUCH.

Fig. 1 is the flow chart of the embodiment of the invention one.As shown in Figure 1, the embodiment of the invention one mainly may further comprise the steps:

Step 101, network side be according to the schedule information (SI) of UE, confirms to distribute to the parameter of the semi-static E-PUCH of said UE, and said parameter is notified to said UE; Said parameter comprises: distribute to the cycle P of the semi-static E-PUCH of said UE, the number of sub frames N that each transmission time interval (TTI) is comprised _TTI, number L, the interval G of adjacent said TTI and the number N that in each subframe of each said TTI, distributes to the semi-static E-PUCH of said UE of said TTI in each said cycle _E-UCCH, power mandate, node and occupied gap information.

In this step; Network side needs earlier according to the schedule information of UE, confirms to distribute to the information such as E-PUCH resource, watt level of this UE, confirms to distribute to the parameter of the semi-static E-PUCH of UE then based on this; Particularly; The method of confirming to distribute to the information such as E-PUCH resource, watt level of this UE according to schedule information can adopt existing method to realize, repeats no more at this, describes respectively in the face of the concrete grammar of confirming above-mentioned each parameter down:

The method of confirming the cycle P of above-mentioned semi-static E-PUCH has the method in the 3GPP standard together now.The method of number L of confirming said TTI is with the method for the number of subframes L that confirms to distribute to UE in the existing 3GPP standard.

Confirm the included number of subframes N of said each TTI _TTIMethod following:

According to the 3GPP standard, when the service rate of UE application is 12.2kbps and should business during through the DPCH transmission, each TTI length of DPCH is: 4 sub-frame; When the service rate of UE application is 64kbps, 128kbps, 256kbps or 384kbps and should business during through the DPCH transmission, the length of each TTI of DPCH be: 2 sub-frame, 4 sub-frame or 8 sub-frame.

Therefore, when the business of RNC decision UE during through semi-static E-PUCH transmission, the included number of subframes of each TTI of semi-static E-PUCH when RNC can confirm that according to the TTI of DPCH this business is transmitted through semi-static E-PUCH according to the service rate of UE application.Such as: when transmitting the 12.2kbps business through semi-static E-PUCH, the included number of subframes N of each TTI of said semi-static E-PUCH _TTI=4; When through semi-static E-PUCH transmission 64kbps, 128kbps, 256kbps or 384kbps when professional, the included number of subframes N of each TTI of said semi-static E-PUCH _TTICan get the arbitrary value in 2,4 and 8.

Definite method of interval G between the adjacent TTI: according to the cycle P of the semi-static E-PUCH that distributes to UE and the number L of TTI, the length N of TTI _TTI, confirm the interval G between adjacent two TTI according to L TTI even distribution in each cycle.

Distribute to the number N of the semi-static E-PUCH of said UE in each subframe of each said TTI _E-UCCH, power mandate, node and the occupied isoparametric definite method of gap information see also existing 3GPP standard and existing document.

This step is through being provided with parameter N _TTI(N _TTI＞1) can adjust the degree of depth that interframe interweaves, N _TTISize be directly proportional with the degree of depth that interframe interweaves.Gain is just big more though darker its interframe of the interframe interleave depth of data block interweaves, and correspondingly, the decoding performance of this data block is just good more.But, when the interframe interleave depth acquires a certain degree, further increase the degree of depth that interframe interweaves again, just not obvious to the lifting of data block decoding performance.And the interframe interleave depth is big more, and the time delay that this data block is deciphered will be big more, and the time delay of uplink service is also big more.When the uplink service time delay acquires a certain degree, the user to the impression of uplink service with variation.Therefore, the length that interframe interweaves is not that the longer the better, but suitably long, and those skilled in the art can confirm suitable N through emulation experiment _TTIValue.

Step 102, said UE are according to the said cycle P, the said N that receive _TTI, said L and said interval G, confirm in each said cycle, to distribute to the position of each subframe among self L the said TTI; According to E-UCCH number N on the semi-static E-PUCH that in each subframe of each said TTI, distributes to said UE _E-UCCH, semi-static E-PUCH power mandate β _{0, e}, the node of semi-static E-PUCH and the occupied gap information of semi-static E-PUCH, confirm the maximum length N of the E-DCH data block that UE can carry in each TTI _Max

According to the cycle P of the semi-static E-PUCH that distributes to said UE, the number of sub frames N that each transmission time interval (TTI) is comprised _TTI, in each said cycle the interval G of number L, the adjacent said TTI of said TTI to confirm in n cycle, to distribute to the method for the subframe number SFN of i sub-frame among l the TTI of UE following:

N in each TTI that distributes to UE _TTIWhen sub-frame was continuous dispensing, the computing formula of in n cycle, distributing to the subframe number SFN of i sub-frame among l the TTI of UE was following:

SFN＝n·P+(i-1)+(l-1)·G，n∈N，i＝1，......，N _TTI，l＝1，......，L

In the following formula, the unit of P is: subframe; The unit of G is: subframe; N _TTIUnit be: subframe.

N in each TTI that distributes to UE _TTIWhen sub-frame is continuous dispensing, can adopt similar formula to calculate: the subframe number SFN that in n cycle, distributes to i sub-frame among l the TTI of UE according to the mode of discontinuous distribution.

For example: establish the N that distributes to UE in each TTI _TTIThe method of salary distribution of sub-frame is: in length is 2N _TTIThe even number sub-frame allocation is given UE in the sub-frame, and the odd number subframe is not distributed to UE.Then

The subframe number SFN that in n cycle, distributes to i sub-frame among l the TTI of UE is according to computes:

SFN＝n·P+2(i-1)+(l-1)·G，n∈N，i＝1，......，N _TTI，l＝1，......，L

Here, UE will according to the power mandate of the semi-static E-PUCH that distributes to it, distribute to its semi-static E-PUCH node, distribute to the occupied time slot of its semi-static E-PUCH and distribute to the TTI length N of its semi-static E-PUCH _TTI, confirm the maximum length N of the E-DCH data block that UE can carry in each TTI _MaxConfirm said N _MaxConcrete grammar can for:

Suppose that in length be N _TTIIn each subframe in the TTI of sub-frame, the power mandate that NODEB distributes to the semi-static E-PUCH of UE is β _{0, e}, the spreading factor that node adopted of distributing to the semi-static E-PUCH of UE is: SF, distribute to the number of time slot that the semi-static E-PUCH of UE occupies and be: T, the number of distributing to the E-UCCH of UE is N _E-UCCH, be N then in length _TTIIn the TTI of sub-frame, the length N of the E-DCH symbol sebolic addressing that UE can carry _sFor:

$N_s=N_{\mathrm{TTI}}\·(\frac{16N_{44}T}{\mathrm{SF}}-17N_{E-\mathrm{UCCH}})$

In the following formula, N ₄₄Represent the number of symbols that channel code that 1 spreading factor is SF=16 can be carried.

Power mandate β according to an E-PUCH subframe _{0, e}, can calculate following information.

When through QPSK modulation transmissions E-DCH data block, effective code check λ of the E-DCH data block of the last carrying of E-PUCH _QPSK(β _{0, e}).

When through 16QAM modulation transmissions E-DCH data block, effective code check λ of the E-DCH data block of the last carrying of E-PUCH _16QAM(β _{0, e}).

RNC is configured to following two forms can for NODEB and UE:

Mapping relations form under the QPSK modulation between effective code check and the power mandate;

Mapping relations form under the 16QAM modulation between effective code check and the power mandate.

UE can dispose the power mandate β to its semi-static E-PUCH according to mapping relations form and the NODEB between effective code check and the power mandate under the above-mentioned QPSK/16QAM modulation _{0, e}, calculate above-mentioned λ _QPSK(β _{0, e}) and λ _16QAM(β _{0, e}).Concrete calculating λ _QPSK(β _{0, e}) and λ _16QAM(β _{0, e}) formula sees also the 3GPP standard.

According to the effective code check under above-mentioned QPSK modulation and the 16QAM modulation, can calculate and adopt under the QPSK/16QAM modulation maximum length N of the E-DCH data block that the E-PUCH of a TTI can carry _QPSK(β _{0, e}) and N _16QAM(β _{0, e}).

In the following formula;

expression rounds under the x, gets the maximum integer that is not more than x that is:.

Then the maximum length of the E-DCH data block that can carry of the E-PUCH of 1 TTI is:

N _max＝max{N _QPSK(β _0，e)，N _16QAM(β _0，e)}

In the following formula, max{x, y} represent to get the maximum between x and the y.

In step 103, each the said TTI that distributes to said UE in each said cycle, said UE is according to said N _Max, be created on the E-DCH data block that needs transmission in this TTI, according to said E-DCH data block, the mode that interweaves according to interframe generates N _TTIThe semi-static E-PUCH signal of sub-frame also sends to the base station.

Here, it is identical with correlation technique in the 3GPP standard to generate the method for E-DCH data block.

In this step, when UE generates the E-DCH data block, the data of UE prioritised transmission high priority logic channel.

When the E-DCH of UE data volume is big, UE will make the E-DCH data block of assembling big as far as possible, but the maximum length of this data block can not be greater than N _Max

When the E-DCH of UE data volume hour, possibly occur: the length of the E-DCH data block that is made up of all E-DCH data is much smaller than N _Max

In the 3GPP standard, 64 subscripts of E-DCH data block length have been stipulated, the concrete length value of the corresponding E-DCH data block of each subscript.Use N _u, u=0,1,2 ... .., the corresponding length value of u subscript of 63 expressions.

When the length of the E-DCH data block of UE assembling is N _E-DCHThe time, at all 64 length value N _u, u=0,1,2 ... .., in 63, from more than or equal to N _E-DCHThe all length value in select a minimum value N _vN _vAccording to computes:

$N_v=\underset{u}{\min }\left\{N_u\right|N_u\≥N_{E-\mathrm{DCH}},u=\mathrm{0,1,2},......,63\}$

The data block length of E-DCH is: N _vThe following of the data block length of E-DCH is designated as: v.With this subscript of six binary number representations v, six bits that this six bit is corresponding are exactly six bits of following target that E-UCCH goes up the E-DCH data block of carrying.

In practical application, generate the N in any TTI _TTIThe semi-static E-PUCH signal of sub-frame can adopt following two kinds of methods to realize; The main distinction of two kinds of methods is that the interleaving mode that is adopted is different; Interweaving the symbolization level in the method one; To adopt interweaving of bit-level in the method two, two kinds of concrete implementation methods through step 103 are elaborated to this below:

In the sending method of semi-static E-PUCH of the present invention, the length of TTI is N _TTICarry an E-DCH data block in each TTI, therefore, each TTI only need feed back an ACK/NACK information.But semi-static E-PUCH carries a data block in each subframe in the existing 3GPP standard, and therefore, the E-PUCH of each subframe need feed back an ACK/NACK information.

According to existing 3GPP standard, the timing relationship that each semi-static E-PUCH subframe and being used to is fed back between the E-HICH subframe of this subframe ACK/NACK information is: the ACK/NACK information of the E-PUCH of m subframe will be through m+d _E-HICHThe E-HICH of sub-frame feeds back to UE.
