Description

A kind of implementation method of multi-carrier HSUPA

Technical field

The present invention relates to high speed uplink packet and insert (HSUPA) technology, particularly a kind of implementation method of multi-carrier HSUPA.

Background technology

At present, the 3GPP standard has provided the implementation method of single carrier HSUPA.In single carrier HSUPA implementation method, the NODEB side need be achieved as follows process:

Each HSUPA carrier wave in each residential quarter of NODEB has a HSUPA scheduler (being designated hereinafter simply as scheduler), and this scheduler is realized the scheduling of HSUPA UE on this carrier wave.In the NODEB side, can dispose the E-HICH of several E-AGCH and several scheduling on each HSUPA carrier wave.Each HSUPA carrier wave has the independently resource pool of the E-PUCH of scheduling.In the NODEB side, the scheduler of each HSUPA carrier wave can distribute the E-HICH set of an E-AGCH set and a scheduling for each the HSUPA UE on this carrier wave: scheduler is selected a part of E-AGCH from the E-AGCH of this carrier wave, as the E-AGCH set of a HSUPA UE on this carrier wave; From the E-HICH of the scheduling of this carrier wave, select a part of E-HICH, as the E-HICH set of the scheduling of this UE.NODEB reports RNC with E-AGCH set and the E-HICH set of each UE on each carrier wave, and RNC gives this UE with E-AGCH set and the E-HICH set configuration of each UE.The scheduler of each HSUPA carrier wave is once dispatched in each subframe, by the UE that selects the HSUPA UE of scheduling from this carrier wave to be scheduled, and be that each UE that is scheduled selects an E-AGCH from the E-AGCH set of this UE, E-AGCH as the scheduling of this UE, from the E-HICH set of the scheduling of this UE, select an E-HICH, E-HICH as the scheduling of this UE, and from the E-PUCH resource pool that this carrier wave is dispatched, select a part of E-PUCH resource, as the E-PUCH of the scheduling of this UE.The E-AGCH of the scheduling of this UE, E-PUCH and E-HICH are on same carrier wave, and the timing relationship of these three interchannels is determined by the 3GPP standard.E-AGCH by scheduling, NODEB sends to this UE with the E-DCH control information of the UE that is scheduled, then according to timing relationship, NODEB receives the E-DCH data block that the E-PUCH of UE by scheduling sends, and according to timing relationship the ACK/NACK information of this E-DCH data block E-HICH by scheduling is fed back to UE.If an E-DCH data block is correctly received, this E-DCH data block will be sent to the MAC-E entity of this UE on this carrier wave.The MAC-E entity of UE will carry out relevant treatment to the E-DCH data block from this UE.Each HSUPA UE has the E-DCH transmission channel of a unique scheduling type, and the data block of scheduling type is sent to NODEB by the E-PUCH of the scheduling by distributing to this UE on this channel after coding.Send to the E-DCH control information of UE by E-AGCH, be used for the transmission of E-PUCH and the reception of E-HICH by UE.

In single carrier HSUPA implementation method, the UE side need be achieved as follows process:

Each HSUPA UE has a MAC-E entity.This entity is realized the MAC layer data processing of UE side HSUPA.Each UE only supports a HSUPA carrier wave, and the professional relevant physical channel of the HSUPA of this UE all is dispensed on the same carrier wave.The professional relevant physical channel of these HSUPA comprises: E-AGCH, E-PUCH and E-HICH.UE distributes to monitoring each E-AGCH in its E-AGCH set, if UE finds that an E-AGCH sends to it, UE can obtain the E-DCH control information by the data on the decoding E-AGCH.UE is by the E-DCH control information, can determine to distribute to its E-PUCH of scheduling and the E-HICH of scheduling, and can determine the timing relationship of these three interchannels.The MAC-E entity of UE can be formed the E-DCH data block according to the E-DCH control information.This E-DCH data block through coding after, sent to NODEB by the E-PUCH channel of the scheduling of UE by distributing to it.UE also will receive the E-HICH of the scheduling of distributing to it according to timing relationship.UE is by going up the detection of ACK/NACK information to E-HICH, can determine whether the E-DCH data block that it sends to NODEB is correctly received.

Above-mentioned single carrier HSUPA implementation method can effectively improve up peak rate and the uplink throughput of UE.But because UE is merely able to support a HSUPA carrier wave, therefore, the up peak rate of single carrier HSUPAUE and the raising of uplink throughput are all very limited.

Embodiment

For making purpose of the present invention, technological means and advantage clearer, below in conjunction with accompanying drawing the present invention is described in further details.

Basic thought of the present invention is: when distributing the E-PUCH resource for the UE that supports a plurality of HSUPA carrier waves, allow to dispatch simultaneously by an E-AGCH a plurality of HSUPA carrier waves of UE.That is: by sending the once E-AGCH of scheduling, the E-PUCH resource on a plurality of HSUPA carrier waves of this UE support in the subframe is distributed to this UE.

Particularly, in the multi-carrier HSUPA implementation method of the present invention, there is a scheduler each residential quarter of NODEB side, the combined dispatching of all HSUPA UE on all HSUPA carrier waves in this scheduler realization residential quarter.In each subframe, the scheduler of this residential quarter carries out a HSUPA scheduling, by the scheduling UE that selection is scheduled all HSUPA UE in the residential quarter, is that each UE that is scheduled determines E-AGCH, the E-PUCH of scheduling of scheduling and the E-HICH of scheduling.Here, distributing to E-AGCH, E-PUCH and the E-HICH of the scheduling of same UE can be on same carrier wave.The E-PUCH that distributes to the scheduling of UE can be across a plurality of carrier waves of UE support.

From system side and UE side specific implementation method of the present invention is described respectively below.

At first, the introducing system side wherein specifically comprises E-AGCH configuration, the configuration of E-PUCH resource pool and E-HICH configuration for the configuration of multi-carrier HSUPA resource.

(1) E-AGCH configuration

At a N frequency point cell, the number of establishing HSUPA carrier wave in the residential quarter is K≤N.RNC is several E-AGCH of this cell configuration, and these E-AGCH can be configured in arbitrarily on the HSUPA carrier wave or arbitrarily on the carrier wave.Preferably, can continue to use in the 3GPP standard restriction to E-AGCH, the number of E-AGCH can not be greater than 32 in N frequency point cell.When being cell configuration E-AGCH, need to specify the frequency at each E-AGCH place.

For each HSUPA UE in the residential quarter, NODEB distributes the E-AGCH set need for this UE.Under single carrier HSUPA situation, comprise 4 E-AGCH at most in this E-AGCH set, under the multi-carrier HSUPA situation, the E-AGCH number in the E-AGCH of each UE set also can suitably be expanded as greater than 4 E-AGCH.Each E-AGCH in the E-AGCH set of this UE is selected to obtain from the E-AGCH of residential quarter by NODEB.After the E-AGCH set of determining UE, report RNC by NODEB, disposed to UE by RNC.

When HSUPA UE was scheduled, NodeB selected an E-AGCH to dispatch to this UE from the E-AGCH set of this UE.When a UE is dispatched continuously, adopt same E-AGCH in the E-AGCH set of this UE as the E-AGCH of the scheduling of this UE.

(2) configuration of E-PUCH resource pool and E-PUCH resource

RNC will be E-PUCH resource pool of each HSUPA carrier wave configuration in the residential quarter.This resource pool is shared by the E-PUCH of non-scheduling on this carrier wave and the E-PUCH of scheduling.The resource that from this resource pool the E-PUCH of non-scheduling is taken is got rid of, and remaining resource is exactly the E-PUCH resource of scheduling.Because the E-PUCH of non-scheduling adopts frame to divide the multiplex mode definition, therefore, the shape of the E-PUCH resource pool of dispatching at each HSUPA carrier wave of each subframe may be different with size.

If there is not the E-PUCH of non-scheduling on HSUPA carrier wave, then RNC gives the E-PUCH resource pool of scheduling of as many as this carrier wave of E-PUCH resource pool of this carrier wave configuration.And this resource pool remains constant in each subframe shape and size.

The E-PUCH resource pool of the scheduling on all HUSPA carrier waves lumps together the E-PUCH resource pool of the scheduling that constitutes a residential quarter, and this resource pool is across K HSUPA carrier wave.In each subframe, because the size of the E-PUCH resource pool of the scheduling on each HSUPA carrier wave may be different with shape in the residential quarter, therefore, possible different with size in the shape of the E-PUCH resource pool of the scheduling of each subframe residential quarter.

The configuration of the E-PUCH resource of UE is divided into three kinds: the E-PUCH configuration of non-scheduling, the E-PUCH configuration of scheduling and semi-static E-PUCH configuration.For the UE that does not support SPS (semi-persistent scheduling), this UE can only have the E-PUCH of non-scheduling E-PUCH and scheduling.For the UE that supports SPS, this UE can only have non-scheduling E-PUCH and semi-static E-PUCH.

Wherein, disposed the E-PUCH of non-scheduling for HSUPA UE by RNC.Particularly, when RNC disposes the E-PUCH of non-scheduling for a UE, need to specify the frequency at this E-PUCH place, the frame of this E-PUCH to divide multiplexing parameters and power mandate etc.And to specify the E-HICH of a non-scheduling and a signature sequence group on this E-HICH for this E-PUCH.UE feeds back ACK/ACK information and the TPC﹠amp of the E-PUCH of this non-scheduling by one group of signature sequence on this E-HICH; The SS command information.This signature sequence group is made of four continuous signature sequences of logic ID.The E-PUCH of this non-scheduling and corresponding E-HICH can be on same carrier waves, also can be on different carrier waves.This configuration allows E-HICH to be configured in pairs on the carrier wave, saves the shared channel code resource of E-HICH.

RNC can adopt the non-scheduling E-PUCH resource of following dual mode configuration UE.

(1) carrier wave level configuration: when UE has the E-PUCH resource of non-scheduling at a carrier wave or a plurality of carrier wave, under this carrier wave level configuration mode, RNC is the non-scheduling E-PUCH of configuration UE on each HSUPA carrier wave respectively.RNC need specify the frame branch multiplexing parameters of the carrier wave at each non-scheduling E-PUCH place of UE and this E-PUCH and power mandate etc.And can specify the E-HICH of a non-scheduling and a signature sequence group on this E-HICH for the non-scheduling E-PUCH on each carrier wave.The E-PUCH of non-scheduling and the E-HICH of non-scheduling can be also can be on same carrier waves on the same carrier wave.Under this configuration mode, the configuration of the non-scheduling E-PUCH of UE on different carrier is separate, and the non-scheduling E-PUCH of UE on different carrier can have different power mandates, different code channel resource and different time-gap resource.

(2) UE rank configuration: the E-PUCH that has non-scheduling as UE at one or more carrier waves, and when the non-scheduling E-PUCH of this UE on different carrier has identical power mandate, identical code channel resource with identical time interval resource, RNC can pass through UE rank configuration mode, finishes the configuration to the non-scheduling E-PUCH of UE.Particularly, under this configuration mode, RNC need list each occupied carrier wave of non-scheduling E-PUCH that UE is given in configuration, and indicate power mandate, code channel resource and the time interval resource of non-scheduling E-PUCH on each carrier wave that is assigned with of UE, and be that E-PUCH on each carrier wave specifies a signature sequence group on an E-HICH and this E-HICH.The E-HICH of the E-PUCH on each carrier wave and this E-PUCH correspondence can be on same carrier wave, also can be not on same carrier wave.

By NodeB for not supporting the E-PUCH resource of HSUPA UE allocation schedule of SPS.Particularly, the HSUPA scheduler of each residential quarter of NODEB is dispatched in each subframe, the E-PUCH of the scheduling that the UE that is scheduled for each distributes can be across a plurality of HSUPA carrier waves, and have identical power mandate, identical code channel resource and identical time interval resource in the scheduling E-PUCH that each carrier wave is distributed to UE.This E-PUCH is that UE owns in the E-PUCH subframe of distributing to UE only.The mandate of this E-PUCH is notified UE by E-AGCH.The E-HICH that feeds back the ACK/NACK information of E-PUCH on each carrier wave can be positioned at same carrier wave with E-PUCH also can be at different carrier.When NODEB gave the E-PUCH resource of UE allocation schedule by E-AGCH, E-AGCH adopted E-AGCH TYPE 1 form.

UE for supporting SPS disposes semi-static E-PUCH by NODEB for this UE.In a single day NODEB gives UE with semi-static E-PUCH resource distribution, and this resource is just monopolized by UE.Unless NODEB discharges this resource by E-AGCH designated command UE, this resource could be regained by NODEB.When NODEB determined to distribute semi-static E-PUCH to UE, NODEB distributed to its semi-static E-PUCH equally by E-AGCH notice UE.Be used for distributing the E-AGCH of semi-static E-PUCH to adopt E-AGCH TYPE 2 forms.For the UE that supports SPS, NODEB distributes to the semi-static E-PUCH of this UE can be across a plurality of HSUPA carrier waves, and have identical power mandate, identical code channel resource and identical time interval resource at the semi-static E-PUCH that each carrier wave is distributed to UE.

(3) configuration of E-HICH

In supporting the N frequency point cell of K carrier wave, can dispose several E-HICH, these E-HICH can be configured in arbitrarily on the HSUPA carrier wave or on any carrier wave.Preferably, can continue to use in the 3GPP standard restriction to E-HICH, the number of E-HICH can not be greater than 32 in N frequency point cell.In the time of configuration E-HICH, need indicate the frequency at this E-HICH place.

E-HICH is divided into the E-HICH of non-scheduling and the E-HICH of scheduling.

When each non-scheduling E-HICH of configuration, adopt the configuration mode of existing non-scheduling E-HICH.

When the E-HICH of each scheduling of configuration, can adopt following dual mode configuration:

(1) E-HICH implicit expression configuration: under this configuration mode, when each E-HICH of configuration, specify the corresponding HSUPA carrier wave of this E-HICH k.The relevant information of the last E-PUCH of HSUPA carrier wave " k " in the residential quarter (comprising: ACK/NACK information and TPC order) feeds back to UE by the signature sequence on this E-HICH.Corresponding relation between the E-PUCH carrier wave that namely can specify this E-HICH and be scheduled, this corresponding relation is used for showing: some carrier wave k go up the relevant information of E-PUCH by the E-HICH feedback of an appointment in K the HSUPA carrier wave, this E-HICH can be identical with the carrier wave k frequency of correspondence, also can use different frequencies.

(2) E-HICH resource pool configuration: RNC gives the E-HICH of cell configuration K scheduling supporting K HSUPA carrier wave.These E-HICH can be configured on any HSUPA carrier wave or arbitrarily on the carrier wave.These E-HICH form the ACK/NACK information of E-PUCH on K HSUPA carrier wave of feedback and the E-HICH resource pool of TPC command information.

Each E-HICH goes up 80 signature sequences of carrying, the logic ID of these signature sequences from 0 to 79.Carry 80 * K signature sequence on K the E-HICH altogether.These signature sequences are formed a signature sequence resource pool.K E-HICH go up from logic ID be 0 signature sequence be 79 signature sequence to logic ID according to order constitute this signature sequence resource pool the (k-1) the individual signature sequence of a * 80+1} signature sequence to the (k*80), here, k=1,2 ..., K.

The ACK/NACK information of the E-PUCH of UE on k HSUPA carrier wave and TPC command information are by two signature sequence feedbacks of this resource pool, and definite method of the logic ID of these two signature sequences is set forth hereinafter.The purpose of the resource pool configuration mode of this E-HICH is: the signature sequence of the relevant information of E-PUCH on each carrier wave that feeds back same UE is positioned on the same E-HICH as far as possible.This configuration mode is conducive to reception and the power saving of UE.

Next introduce the function of HSUPA scheduler of each residential quarter of NodeB side.

In the multi-carrier HSUPA implementation that the present invention proposes, there is an independently HSUPA scheduler each residential quarter of NODEB side.The combined dispatching of all HSUPA UE on all HSUPA carrier waves in this HSUPA scheduler realization residential quarter.For the UE that does not support SPS, scheduler is given the E-PUCH of UE allocation schedule; For the UE that supports SPS, scheduler distributes semi-static E-PUCH to UE.The operation of concrete combined dispatching comprises:

The HSUPA scheduler of each residential quarter is once dispatched in each subframe.During scheduling, UPH (uplink power margin) information and SNPL (Serving cell and adjacent residential quarter path loss) information and other relevant informations that NODEB will report based on each UE are determined the UE that is scheduled.Should be under the interference max-thresholds that the NODEB side is set for this carrier wave in the interference that all UE that are scheduled on the carrier wave cause adjacent residential quarter.

For the UE that does not support SPS, when this UE was scheduled, scheduling only took a subframe for the E-PUCH resource of UE, but can be across a plurality of HSUPA carrier waves in this subframe.UE is identical with time interval resource information at each power authorization message, code resource information of distributing on its HSUPA carrier wave.That is: as the E-PUCH that distributes to a UE during across a plurality of carrier wave, the E-PUCH that distributes to this UE at each carrier wave has identical time slot, identical code channel and identical power mandate.Specifically, when a UE was scheduled, scheduler need be determined following schedule information for each UE that is scheduled:

(1) carrier wave that is scheduled: because each UE supports 6 HSUPA carrier waves at most, represent the situation that carrier wave is scheduled with 6 bits.K bit is that k the HSUPA carrier wave that 1 this UE of expression supports is scheduled to this UE; K bit is that k the HSUPA carrier wave that 0 this UE of expression supports is not scheduled to this UE.

(2) power mandate (PRRI) information that this UE obtains on each is scheduled carrier wave.This PRRI information adopts 5 bits to represent, and is identical under the mapping relations between 5 PRRI bits and the power authorization value and the single carrier case.

(3) distribute to channel code resource (CRRI) information of this UE at each carrier wave that is scheduled.This CRRI information adopts 4 bits to represent, 4 CRRI bits and UE use under mapping relations between the channel code node and the single carrier case identical.Here, the minimum particle size of code channel mandate is the channel code of a SF=8.

(4) distribute to time interval resource (TRRI) information of this UE at each carrier wave that is scheduled.This TRRI information adopts 5 bits to represent, and is identical under the mapping relations between 5 TRRI bits and the timeslot number and the single carrier case.

(5) determine the number of E-UCCH on each carrier wave.Based on the requirement of E-UCCH decoding performance, determine that the E-PUCH that is scheduled goes up the number of E-UCCH.This information adopts 3 bits to represent, and is identical under the mapping relations between 3 bits and the E-UCCH number 1-8 and the single carrier case.

(6) E-HICH information.E-HICH information dispose dual mode: E-HICH implicit expression configuration mode and E-HICH resource pool configuration mode.No matter adopt which kind of configuration mode, need when each this UE is scheduled, not give UE with corresponding E-HICH information configuration.

(6-1) E-HICH implicit expression configuration: owing in the E-HICH configuration, indicated the E-HICH of each HSUPA carrier wave correspondence.Therefore, when being scheduled, a UE just do not need to specify corresponding E-HICH specially for UE.

(6-2) E-HICH resource pool configuration: under this configuration mode, the resource pool of signature sequence formation on K E-HICH, the relevant information of the E-PUCH of UE on each carrier wave feeds back to UE by two signature sequences of this resource pool.Definite method of the logic ID of these two sequences is introduced hereinafter.Under this mode, need when UE is scheduled, the E-HICH configuration information not sent to UE yet.

(7) specify the E-AGCH that dispatches for the UE that is scheduled.From the E-AGCH set of this UE, select an E-AGCH as the E-AGCH of the scheduling of this UE.When UE is dispatched continuously, adopt identical E-AGCH as the E-AGCH of the scheduling of this UE.

(8) determine timing relationship between the E-HICH of the E-PUCH of E-AGCH, scheduling of scheduling and scheduling for the UE that is scheduled.According to the 3GPP standard, E-AGCH sends n subframe, and then E-PUCH sends n+2 subframe, and E-HICH sends n+2+D subframe.D is decided by the slot time between E-PUCH and the E-HICH.This slot time n _E-hichDetermine to report later RNC by NODEB, give UE by RNC with this parameter configuration.

(9) determine the E-DCH control information according to above-mentioned schedule entries, this E-DCH control information is exactly that the E-AGCH that dispatches goes up data carried by data.

(10) scheduler is after the scheduling that finishes current subframe, and the following message of the UE that each need be scheduled sends to the physical layer of NODEB.

(10-1) the E-AGCH ID of the scheduling of UE and subframe number " n ".

(10-2) Tiao Du E-PUCH information and subframe number " n+2 ".E-PUCH information comprises: the frequency point information of E-PUCH, power authorization message, code resource information and time interval resource information etc.

(10-3) Tiao Du E-HICH ID and subframe number " n+2+D "

(10-4) E-AGCH goes up data carried by data, that is: E-DCH control information.

After determining above-mentioned schedule information, scheduler just is through with in current subframe to a scheduling of not supporting the UE of SPS.

For the UE that supports SPS, in the scheduling of each subframe, the HSUPA scheduler will distribute semi-static E-PUCH to the UE that supports SPS.The semi-static E-PUCH that distributes to UE can be across a plurality of carrier waves of UE support.The semi-static E-PUCH that distributes to UE at each carrier wave has identical power mandate, identical code channel resource and identical time interval resource.In a single day NODEB distributes to UE with semi-static E-PUCH, this resource is just monopolized by UE.Distribute to the semi-static E-PUCH of UE inappropriate the time when NODEB finds it, will discharge by E-AGCH designated command UE and distribute to the semi-static E-PUCH of this UE, and will redistribute suitable semi-static E-PUCH for UE.

In each residential quarter of NODEB, each UE has a MAC-E entity in this residential quarter, and the E-DCH data block of the corresponding UE that this entity need report the NODEB physical layer reports the MAC-ES entity of this UE that is positioned at RNC later on through relevant treatment.Concrete MAC-E data handling procedure is not content of the present invention, repeats no more.

In the multi-carrier HSUPA implementation method, because a plurality of carrier waves of a UE may be dispatched simultaneously.Therefore, need be at this multicarrier combined dispatching situation, the corresponding physical layer procedure of clear and definite system side.

For the UE that does not support SPS, when a plurality of HSUPA carrier waves of this UE were dispatched simultaneously, the physical layer procedure under the multicarrier combined dispatching was to be different from correlated process under the single carrier case.To describe in detail below.

(1) the DLPC process of E-AGCH

For each UE that is scheduled, UE and NODEB need to realize the DLPC based on the E-AGCH of GAP.Specifically, UE determines that according to the reception SNR of E-AGCH the DLPC of E-AGCH orders, and brings NODEB with the TPC order that generates by the TPC command field on the E-PUCH of scheduling.Because therefore the E-PUCH of scheduling, can stipulate probably across a plurality of carrier waves: the TPC order of E-AGCH is carried to NODEB by the TPC territory of the E-PUCH of first carrier wave (carrier wave of number of carriers minimum).The TPC order in TPC territory on first carrier wave can be left unused or retransmit in the TPC territory of the E-PUCH of other carrier waves.

The DLPC of the E-AGCH of UE begins progressively to enter the closed power control procedure by first E-AGCH subframe.When the scheduling interval that E-AGCH occurs, if this interval less than the threshold value GAP that sets in advance, then UE still carries out closed power control; If this is not less than the threshold value GAP that sets in advance at interval, then UE restarts to carry out the DLPC of E-AGCH from first later subframe of interval, and then progressively enters the closed power control of E-AGCH.

For NODEB, the transmitting power of first E-AGCH subframe or when at interval being not less than GAP at interval after the transmitting power of first E-AGCH subframe any one mode in can be in the following way determine:

(1) Initial Trans of employing E-AGCH

(2) if other down channels of this UE are arranged at E-AGCH place time slot, and this down channel is in the closed power control procedure or is in the closed power control procedure in E-AGCH interim, then preferably with this down channel as the reference channel, add a power bias as the transmitting power of E-AGCH at this down channel on the transmitting power basis of current subframe.This power bias equals to reaching poor by the SNR of reference channel of the identical needed SNR of BLER desired value E-AGCH and this.

(3) in (2), if there are a plurality of descending channels that are in closed power control in a UE at E-AGCH place time slot, then preferably adopt DL DPCH; If there is not DL DPCH, can adopt HS-SCCH.

After first E-AGCH subframe, NODEB progressively enters closed power control, adjusts the transmitting power of E-AGCH according to the TPC order of the E-AGCH that receives from UE.When scheduling interval appears in E-AGCH, if at interval less than GAP, then NODEB determines the transmitting power of E-AGCH in the following manner:

(1) transmitting power based on the E-AGCH before the interval adds a power bias, the increment that this power bias decreases for UE dypass during the backoff interval.

(2) if there are other down channels of this UE at E-AGCH place time slot, and this down channel has carried out the closed power adjustment in interim, then with this down channel as the reference channel, the power that the power of E-AGCH preferably equals this down channel adds a power bias.This power bias equals to reaching poor by the SNR of reference channel of the identical needed SNR of BLER desired value E-AGCH and this.

(3) in (2), if there are a plurality of channels that carried out the adjustment of downlink closed-loop power in interim in a UE at E-AGCH place time slot, then preferably adopt DL DPCH; If there is not DLDPCH, can adopt HS-SCCH.

(2) DLBF of E-AGCH

The DLBF of E-AGCH is realized by NODEB.All up channels of UE can join together to generate the down beam shaping weight vector, in same subframe, when there is a plurality of up channel in UE, UE generates unique down beam shaping vector by the channel estimation results of these up channels, is used for the wave beam forming of any one down channel of UE.

(3) the ULSC process of E-PUCH

When a UE was scheduled, the E-PUCH of scheduling that distributes to this UE was during probably across a plurality of HSUPA carrier wave, and E-PUCH takies identical time interval resource, identical code channel resource and identical power mandate on all these carrier waves.E-PUCH on these carrier waves adopts identical TA to send.Therefore, all E-PUCH of this UE can carry out combined U LSC according to UE.That is: the ULSC that unites of the E-PUCH on all carrier waves of this UE, NODEB can be obtained the channel estimating of this UE on each carrier wave by the reception signal of E-PUCH on all carrier waves, NODEB can be generated the ULSC order of a unique E-PUCH by the channel estimating of the UE on all carrier waves, and this ULSC order can be carried to UE by the SS territory on the E-AGCH of scheduling.

Specifically, NODEB is when receiving first E-PUCH subframe of this UE transmission, NODEB can be obtained the channel estimating of this UE on each carrier wave at the reception signal of the E-PUCH on each carrier wave by UE in this subframe, NODEB can be generated the ULSC order of unique E-PUCH by the channel estimating of this UE on all carrier waves, and this ULSC order is sent to UE by E-AGCH; Then, NODEB will progressively enter closed loop ULSC by open loop to the ULSC process of this UE.When the transmission of E-PUCH occurred at interval, the ULSC of E-PUCH progressively entered closed loop ULSC by open loop afterwards at interval.

The UE side is carried out combined U LSC to the E-PUCH of the scheduling on all carrier waves.For first E-PUCH subframe, the TA of this subframe can adopt the TA of nearest up channel employing as the TA of current E-PUCH subframe.Then, UE will progressively enter the closed loop ULSC of E-PUCH: extract the ULSC order from E-AGCH, respond this ULSC order, adjust the TA of E-PUCH.When scheduling interval appears in the E-PUCH channel, UE adopt the TA of a nearest up channel send at interval after first E-PUCH subframe, progressively enter the closed loop ULSC of E-PUCH later on, according to the TA of the ULSC order adjustment E-PUCH that extracts from E-AGCH.

Alternatively, UE side ULSC that all up channels of this UE are united.UE obtains the TA of PRACH by the FPACH channel at access procedure.After, UE enters closed loop ULSC process based on this TA.UE adjusts the unique TA of this UE according to the ULSC order of carrying from down channel.In same subframe, the down channel of all these UE carries identical ULSC order.

Correspondingly, the NODEB side realizes the combined U LSC based on UE.NODEB joins together to carry out Synchronization Control with all up channels of a UE.When UE when there is a plurality of up channel in same subframe, the NODEB side group generates a ULSC order in the channel estimating of these all up channels of subframe, this order is sent to UE as the ULSC order of each up channel by the down channel of being correlated with by this UE.All down channels of UE join together to carry the up-to-date ULSC order of this UE that the NODEB adnation becomes.

(4) ULPC of E-PUCH

Because distributing to the E-PUCH of a UE may be across a plurality of carrier wave.The channel of E-PUCH experience is inequality usually on each carrier wave, and the interference of experience is also different usually.Therefore, when a plurality of HSUPA carrier waves of a UE were dispatched simultaneously, the E-PUCH on each carrier wave need carry out ULPC respectively.

For a UE, the E-PUCH of this UE non-scheduling on the E-PUCH of the scheduling on each carrier wave and this carrier wave carries out the ULPC based on GAP.The E-PUCH of non-scheduling has identical Pe-base with the E-PUCH of scheduling.The ULPC process of concrete E-PUCH is as follows:

The UE side adopts open loop approach to determine the transmitting power of E-PUCH when each HSUPA carrier wave sends on this carrier wave first E-PUCH subframe, progressively enters the closed power control procedure then.Scheduling interval appears in the E-PUCH on this carrier wave, if should be at interval less than GAP, then the mode of the Pe-base of first E-PUCH subframe is after the definite interval of UE side: the Pe-base of last subframe adds the increment of interim UE dypass damage at interval, with the Pe-base of summed result as first E-PUCH subframe of back, interval.

When being not less than GAP at interval, then UE side first subframe after at interval adopts open loop approach to determine the Pe-base of E-PUCH.

The NODEB side is carried out the ULPC of E-PUCH as follows.

On each HSUPA carrier wave at this UE place, for first E-PUCH subframe on this carrier wave, NODEB calculates current subframe with reference to the SNR of code check, generate ULPC order (be TPC order) with reference to the SNR of code check with SNR desired value with reference to code check by more current subframe: if SNR greater than the SNR desired value, then NODEB generates " DOWN " order; If SNR smaller or equal to the SNR desired value, then generates " UP " order.The TPC order is sent to UE.

According to the ULPC method of above-mentioned E-PUCH, when only there was the E-PUCH of the non-scheduling of being disposed by RNC in UE on a HSUPA carrier wave, the ULPC order of this E-PUCH was carried to UE by the non-scheduling E-HICH corresponding with this E-PUCH.When UE does not have the E-PUCH of non-scheduling at a HSUPA carrier wave, when having only the E-PUCH of scheduling, the DLPC of the E-PUCH of scheduling order is carried to UE by the E-HICH of scheduling that carries E-PUCH on this carrier wave and go up the ACK/NACK information of E-DCH data block.The E-PUCH of scheduling and the E-HICH of scheduling are one to one under the configuration of E-HICH implicit expression; When E-HICH adopts E-HICH resource pool configuration mode, determine that the method for the E-HICH corresponding with E-PUCH sees also hereinafter.

E-PUCH when UE existing non-scheduling on a HSUPA carrier wave, when the E-PUCH of scheduling is arranged again, the E-PUCH of non-scheduling and the E-PUCH of scheduling join together to realize the ULPC based on the E-PUCH of GAP, and the TPC order of generation is joined together to carry to UE by the E-HICH that the non-scheduling E-HICH corresponding with the E-PUCH of the non-scheduling of this UE and the E-PUCH that carries the scheduling of this UE go up the scheduling of E-DCH data block ACK/NACK information.

In the ULPC of above-mentioned E-PUCH process, the TPC order of each E-PUCH of producing need be handed down to UE.The parameter that is located at the E-PUCH that distributes to UE on each HSUPA carrier wave is as follows:

(1) timeslot number of last time slot of the E-PUCH of this scheduling (that is: the time slot of timeslot number maximum) is t ₀, t ₀Possible value is: 1,2,3,4,5;

(2) at time slot t ₀The number of distributing to the channel code of this UE is q ₀(q ₀Possible value be: 1 ..., Q ₀)

(3) at time slot t ₀Distribute to the channel code q of this UE ₀Spreading factor be Q ₀

Then carry on the E-HICH of scheduling of ACK/NACK information of E-PUCH of above-mentioned scheduling and this E-HICH and carry " definite method of the signature sequence of ACK/NACK information is as follows:

(A) configuration of E-HICH implicit expression is down:

In multi-carrier HSUPA, NODEB distributes the minimum particle size of E-PUCH resource to be: SF=8.Under this partition size, the E-HICH of ACK/NACK information that is used for having on the feedback carrier " k " E-PUCH of above-mentioned E-PUCH parameter can uniquely be determined by the number of carrier wave " k " under E-HICH implicit expression configuration mode.If the E-HICH corresponding with carrier wave " k " is " k " individual E-HICH.Therefore, under the configuration of E-HICH implicit expression, the E-PUCH of last any one UE of carrier wave " k " feeds back the ACK/NACK information of this UE by k E-HICH.This corresponding relation is the RNC configuration, and is notified to NODEB and UE.

The logic ID " r " that is used for the signature sequence on this k E-HICH of ACK/NACK information that feedback carrier " k " goes up E-PUCH is definite by following formula according to the 3GPP standard:

$r=16(t_0-1)+(q_0-1)\frac{16}{Q_0}$

The logic ID of signature sequence of TPC order that is used for having on the feedback carrier " k " E-PUCH of above-mentioned parameter is " R ":

R=r+i, i can arrive at i=1 $i=\frac{16}{Q_0}-1$ Between get a value arbitrarily.

Therefore, under the implicit expression configuration of E-HICH, be respectively for the ACK/NACK information of the E-PUCH that has above-mentioned parameter on feedback " k " individual HSUPA carrier wave and two signature sequences of TPC command information: r and R.Here, can stipulate: when the TPC of needs feedbacks order during for " UP ", calculate the physical I D " RR " of this signature sequence by the logic ID " R " of signature sequence, then physical I D is fed back to UE for the former sequence of the signature sequence of " RR "; When the TPC of needs feedbacks order during for " DOWN ", physical I D is fed back to UE for the antitone sequence of the signature sequence of " RR ".

(B) under the configuration of E-HICH resource pool:

It is as follows to determine that under this configuration mode feedback carrier " k " has the calculation procedure of two signature sequences of the ACK/NACK information of E-PUCH of above-mentioned parameter and TPC order:

The first step: according to $r=16(t_0-1)+(q_0-1)\frac{16}{Q_0}$ Calculate the logic ID of the signature sequence of the ACK/NACK information of feedback UE under implicit expression E-HICH configuration.

Second step: the signature sequence on each E-HICH is divided into 20 groups, i (i=1,2 ..., 20) logic ID of four signature sequences comprising of group is: 4 (i-1)+j, j=0,1,2,3.Judge the group number " g " that r belongs in the first step:

Wherein, The maximum integer that is not more than x is got in expression.

The 3rd step: the number " k that determines to have on the feedback carrier " k " E-HICH of the ACK/NACK information of E-PUCH of above-mentioned parameter and TPC order _h" and this E-HICH on the logic ID " j of related signature sequence _h+ i, i=0,1,2,3 ".

In the signature sequence resource pool that is constituted by K E-HICH, comprise 80 * K signature sequence.Signature sequence in this signature sequence resource pool is divided into 20 * K group, and every group comprises four continuous signature sequences.First group of signature sequence is four signature sequences of first signature sequence to the in the resource pool, and second group is 8 signature sequences of the 5th signature sequence to the in the pond, and the m group is the 4th * (m-1)+1 signature sequence to the 4 * m signature sequence in the pond.

For the signature sequence of the ACK/NACK of E-PUCH and TPC order on the different carrier that makes a UE of feedback is positioned on the same E-HICH as far as possible, regulation: the group number that calculates when second step is: during g=1, UE feeds back to UE in ACK/NACK information and the TPC order that k carrier wave has the E-PUCH of above-mentioned parameter by the group of the k in E-HICH signature sequence resource pool signature sequence; When group number was g=2, UE fed back to UE in ACK/NACK information and the TPC order that k carrier wave has the E-PUCH of above-mentioned parameter by the group of the K+k in E-HICH signature sequence resource pool signature sequence; For g=1 arbitrarily, 2 ..., the ACK/NACK information of the E-PUCH of 20, UE on k carrier wave and TPC order are organized signature sequence by h=(g-1) K+k in the E-HICH signature sequence resource pool and are fed back to UE;

If this h group signature sequence is positioned at " k _h" on the individual E-HICH, logic ID is: j _h+ i, i=0,1,2,3.k _hAnd j _hComputing formula as follows:

Wherein,

The minimum positive integer greater than x is asked in expression.

j _h＝(4(h-1))mod 80

For the ACK/NACK information of the E-PUCH that has above-mentioned parameter on the feedback carrier " k " and the signature sequence group j of TPC command information _h+ i, i=0, the signature sequence " j of logic ID minimum in 1,2,3 _h" be used for the ACK/NACK information that feedback carrier " k " goes up E-PUCH, logic ID time little signature sequence " j _h+ 1 " is used for the TPC command information that feedback carrier " k " goes up E-PUCH.Other two sequences temporarily need not.Here, regulation: be " R=j by logic ID _hThe mode of+1 " signature sequence feedback TPC order is: when the TPC of needs feedback order during for " UP "; calculate the physical I D " RR " of this signature sequence by the logic ID " R " of signature sequence, then physical I D is fed back to UE for the former sequence of the signature sequence of " RR "; When the TPC of needs feedbacks order during for " DOWN ", physical I D is fed back to UE for the antitone sequence of the signature sequence of " RR ".

(5) DLPC of E-HICH

The DLPC of E-HICH is realized that by NODEB concrete mode just repeats no more with existing identical here.

(6) generation of the last ACK/NACK information of E-PUCH

When NODEB dispatches M carrier wave of a UE simultaneously, UE will send M data block to NODEB by this M carrier wave respectively.NODEB needs respectively the data block on M the carrier wave to be carried out joint-detection, demodulation and decoding.NODEB determines to feed back to the ACK/NACK information of UE according to the CRC check result of each data block.If the data block on carrier wave is correctly received by NODEB, NODEB just feeds back to UE with ACK bit by the E-HICH corresponding with this carrier wave; If the data block on carrier wave is received by the NODEB mistake, NODEB just feeds back to UE with the NACK bit by the E-HICH corresponding with this carrier wave.

When a data block was received by mistake, the bit sequence that is used for this data block decoding was saved.When this data block was retransmitted, NODEB needed that this data block is retransmitted the bit sequence to be decoded and this data block bit sequence to be decoded before that obtain and merges, and deciphers to improve the diversity gain of decoding then.

For the UE that supports SPS, when a plurality of HSUPA carrier waves of this UE were dispatched simultaneously, the physical layer procedure under the multicarrier combined dispatching also was to be different from correlated process under the single carrier case.Illustrated below.

For the multicarrier UE that supports SPS, the DLPC process of the E-AGCH of this UE is with the DLPC process of the E-AGCH of the multicarrier UE that does not support SPS.Difference is: for the UE that supports SPS, the DLPC order of the E-AGCH of this UE is carried to NODEB by the TPC territory of the semi-static E-PUCH on first carrier wave, and for the UE that does not support SPS, the DLPC of the E-AGCH of this UE order is carried to NODEB by the TPC territory of the E-PUCH of the scheduling on first carrier wave

For the multicarrier UE that supports SPS, the DLBF process of the E-AGCH of this UE is with the DLBF process of the E-AGCH of the multicarrier UE that does not support SPS.

For the UE that does not support SPS, when dispatching this UE at every turn, E-AGCH (adopting E-AGCH TYPE 1 form) by scheduling only distributes the E-PUCH of a subframe to UE, distribute to a plurality of carrier waves that the E-PUCH of the subframe of this UE can support across this UE, the E-PUCH that distributes to UE at each carrier wave has identical power mandate, identical code channel and identical time interval resource.For the UE that supports SPS, when dispatching this UE, distribute the E-PUCH of a plurality of subframes to UE by the E-AGCH (adopting E-AGCHTYPE 2 forms) that dispatches at every turn.In each E-PUCH subframe of distributing to UE, the E-PUCH resource of distributing to UE is identical: across identical carrier wave, have identical power mandate, identical code channel and identical time interval resource at each carrier wave.Therefore, the semi-static E-PUCH that distributes to the UE that supports SPS can be considered as a kind of E-PUCH that occupies the special scheduling of a plurality of subframes.

Semi-static E-PUCH is being considered as under the E-PUCH situation of special scheduling, the physical layer procedure of the multi-carrier HSUPA UE of support SPS is identical with the physical layer procedure of the multi-carrier HSUPA UE that does not support SPS:

(1) for the UE that supports SPS, when a plurality of carrier waves of this UE were distributed semi-static E-PUCH simultaneously, semi-static E-PUCH realized the ULSC of associating on these carrier waves.

The UE of support SPS does not support the combined U LSC process of UE E-PUCH on a plurality of carrier waves of SPS together in the combined U LSC process of semi-static E-PUCH on a plurality of carrier waves.For the UE that supports SPS, all up channels of this UE can be realized the ULSC process of uniting.The combined U LSC process of all up channels of the UE of this support SPS is with the combined U LSC process of all up channels of the UE that does not support SPS.

(2) for the UE that supports SPS, it is separate, parallel carrying out that this UE gives the ULPC process of the E-PUCH on its carrier wave in each configuration.SPS UE does not support the ULPC process of UE E-PUCH on each carrier wave of SPS together in the ULPC process of E-PUCH on each carrier wave.

(3) for the UE that supports SPS, the DLPC of E-HICH is with the DLPC of existing E-HICH.

For the UE that supports SPS, ACK/NACK information and the TPC﹠amp of the semi-static E-PUCH of this UE on each carrier wave; The SS command information feeds back to UE by the corresponding signature sequence on the E-HICH corresponding with semi-static E-PUCH on this carrier wave.

When NODEB give to support that simultaneously the UE of SPS distributes semi-static E-PUCH on M the carrier wave, UE will have the subframe of semi-static E-PUCH at each, and M the data block of M carrier wave transmission by distributing to it is to NODEB.NODEB needs respectively the data block on M the carrier wave to be carried out joint-detection, demodulation and decoding.NODEB determines to feed back to the ACK/NACK information of UE according to the CRC check result of each data block.If the data block on carrier wave is correctly received, NODEB just feeds back to UE with ACK bit by the E-HICH corresponding with this carrier wave; If the data block on carrier wave is received by mistake, NODEB just feeds back to UE with the NACK bit by the E-HICH corresponding with this carrier wave.

When a data block was received by mistake, the bit sequence that is used for this data block decoding was saved.When this data block was retransmitted, NODEB needed that this data block is retransmitted the bit sequence to be decoded and this data block bit sequence to be decoded before that obtain and merges, and deciphers to improve the diversity gain of decoding then.

Introduce the form of the E-AGCH that is used for the multi-carrier HSUPA scheduling below.

For the UE that does not support SPS scheduling, when dispatching a plurality of HSUPA carrier wave of this UE simultaneously by an E-AGCH, can adopt the E-PUCH of following E-AGCH form indication scheduling.

(2) 2 of the E-HICH indicator field bit (x _{EI, 1}, x _{EI, 2})

(3) the higher bit x of CRRI _{C, 1}

6 bits that therefore, 6 bits in above-mentioned 3 territories in the E-AGCH Class1 can be used for expression FRRI territory.

To supporting the UE of SPS scheduling, when dispatching a plurality of HSUPA carrier wave simultaneously by an E-AGCH, adopt the E-PUCH of following E-AGCH form indication scheduling.Following E-AGCH form is compared with the form of E-AGCH TYPE 2, all be made of 30 information bits, but the information field that comprises is not quite similar.

(1) UE multi-carrier HSUPA ability reports

Among the present invention, UE need report the multi-carrier HSUPA ability of UE by the order of UU message.UE supports 6 HSUPA carrier waves at most simultaneously.When RNC is after UE has disposed the HSUPA carrier wave, RNC need be transmitted to NODEB to the HSUPA carrier information at the multi-carrier HSUPA ability of this UE and this UE place.

About the configuration of E-AGCH, E-PUCH resource and E-HICH, in handling, the aforementioned system side relates to, just repeat no more here.Wherein, when configuration E-HICH, the result of implicit expression configuration issues by PCCPCH broadcasting, can save UU message like this and make resource; Under E-HICH resource pool configuration mode, also issue by PCCPCH broadcasting: tell each HSUPA UE in the residential quarter, the carrier wave at k E-HICH place in the number of the E-HICH that the E-HICH resource pool comprises in the residential quarter " K ", resource pool, the channel code of k E-HICH use, the time slot at place.

Next introduce the MAC-E function of UE side.

In the multi-carrier HSUPA implementation method that the present invention proposes, the UE side has a MAC-E entity.This MAC-E entity is according to the power authorization message of E-PUCH, and code channel resource information and time interval resource information are determined the probable value of HSUPA length of data package.When having a plurality of carrier waves to be dispatched simultaneously in the HSUPA carrier wave that a UE can support, physical layer need with the E-PUCH channel across carrier number M reporting MAC-E entity.The MAC-E entity will generate a data block for each carrier wave, and symbiosis becomes M data block.

The MAC-E entity will be determined the following message of the E-DCH data block of each generation:

Physical layer respectively to each data block encode, modulation and spread spectrum.The coding method of each E-DCH data block is with the coding method of E-DCH data block under the single carrier case.Each carrier wave that is scheduled is used for sending the decoding information of a unique data block and this data block.The decoding information of E-DCH data block is exactly data carried by data on the E-UCCH channel on this carrier wave on each carrier wave.The coding method of data is with the coding method of E-UCCH channel under the single carrier case on the E-UCCH channel.

On the E-PUCH channel of E-DCH bit stream through being mapped to this carrier wave after the ovennodulation that obtains after the E-DCH data block coding on each carrier wave.The bit that obtains after the E-DCH coding flows to the mapping mode of E-PUCH channel with mapping mode relevant under the single carrier case.Modulation is multiplexed on the E-PUCH channel of this carrier wave later the bit stream that obtains after the E-UCCH coding on this carrier wave through QPSK.The E-UCCH channel at the multiplex mode on the E-PUCH with the E-UCCH multiplex mode under the single carrier case.

The modulation system of TPC order that E-PUCH goes up carrying on HSUPA carrier wave adopts the QPSK modulation with the modulation system that E-PUCH under the single carrier case goes up TPC.The TPC order is multiplexed into the mode of E-PUCH with the multiplex mode of TPC order under the single carrier case.

The time slot format of E-PUCH is with the time slot format under the single carrier case on each carrier wave.

The spreading factor of E-PUCH channel and channel code are determined by the code channel resource information on the E-AGCH of scheduling.The spread spectrum mode of E-PUCH is with the spread spectrum mode of E-PUCH under the single carrier case on each carrier wave.

Introduce the physical layer process of UE side at last.

In the multi-carrier HSUPA implementation method, because a plurality of carrier waves of a UE may be dispatched simultaneously.Therefore, need be at this multicarrier combined dispatching situation, clear and definite corresponding physical layer procedure.Physical layer procedure under these multicarrier combined dispatchings is to be different from correlated process under the single carrier case.
