Abstract

The present invention supposes a situation in which an Enhanced Uplink Dedicated transport Channel (EUDCH) is used in a wideband code division multiple access (WCDMA) system. In a user equipment (UE), when physical channels for transmitting EUDCH data are transmitted in addition to existing physical channels, a Peak-to-Average Power Ratio (PAPR) of an uplink transport signal increases. The increase in PAPR depends upon Orthogonal Variable Spreading Factor (OVSF) codes allocated to the corresponding physical channels and In-phase/Quadrature-phase (I/Q) channels. Therefore, the apparatus and method allocate optimum OVSF codes and I/Q channels to EUDCH-related physical channels in order to minimize an increase in PAPR due to EUDCH.

Technical field

The present invention relates generally to asynchronous wide-band code division multiple access (WCDMA) communication system, particularly a kind of be used to be minimized in send of the increase of the peak value of signal during sending through the data of enhanced uplink dedicated transmission channel (EUDCH) to average power ratio (PAPR).

Just, the present invention proposes a kind of optimum orthogonal variable spread spectrum factor (OVSF) code and same phase/quadrature phase (I/Q) channel assigning device and method of uplink physical channel of the EUDCH of being used for service.

Background technology

At present, the up link of WCDMA system comprises Dedicated Physical Data Channel (DPDCH) and Dedicated Physical Control Channel (DPCCH), as the typical dedicated physical channel that is used to send subscriber signal.DPDCH is a data transmission channel, send the user data such as voice and image above that, and DPCCH is the control information transmission channel, and delivery above that is used for DPDCH frame format information and the pilot frequency information that DPDCH separates the control of mediation power.

Recently, proposed to use the technology of EUDCH, with speed and efficient that the grouped data of improving in the up link is sent, wherein EUDCH is enhanced uplink forms data (data-only) transmission channel.

Fig. 1 is the figure that the information that between subscriber equipment and Node B, exchanges in order to carry out up link to send is shown.

With reference to figure 1, UE 110,112,114 sends grouped data with the distance of Node B 100 with different transmitted powers according to them with 116.The UE 110 that is positioned at Node B 100 longest distances sends grouped data with the highest transmitted power 120 that is used for uplink channel, and the UE 114 that is positioned at the Node B beeline sends grouped data with the lowest transmit power 124 that is used for uplink channel.In order to improve the performance of GSM, Node B 100 is operation dispatching by this way, that is, the level that is used for the transmitted power of uplink channel should be inversely proportional to data rate.Just, Node B is distributed to minimum data rate has the UE of high transmitted power that is used for uplink channel, and peak data rate is distributed to the UE with the lowest transmit power that is used for uplink channel.

Fig. 2 is the figure that the information that between UE and Node B, exchanges in order to carry out up link to send is shown.Just, Fig. 2 shows in order to send through the grouped data of EUDCH required basic process between Node B 200 and UE 202.

With reference to figure 2,, between Node B 200 and UE 202, set up EUDCH in step 210.Step 210 comprises the processing through dedicated transmission channel transmission/reception message.After step 210, UE 202 will send to Node B 200 about the information of desired data rates and the information of expression uplink channel conditions in step 212.The information of expression uplink channel conditions comprises the transmitted power of the uplink channel that is sent by UE 202 and the transmitted power tolerance limit of UE 203.

The Node B 200 of receiving uplink channel transmitted power can be through comparing the uplink channel transmitted power estimating down-ward link channel condition with received power.Just, Node B 200 thinks that if the difference of uplink channel transmitted power and uplink channel received power is little, then uplink channel conditions is good, and thinks, if the difference of transmitted power and received power is big, then uplink channel conditions is poor.When UE sent the transmitted power tolerance limit with the estimating uplink channel condition, Node B 200 can be come the estimating uplink transmitted power through knowing and possibly deduct the transmitted power tolerance limit by maximum transmit power from the sixth of the twelve Earthly Branches that is used for UE.Node B 200 is used the estimation channel condition of UE 202 and the information of the data rate that requires about UE 202 confirms to be used for the possible maximum data rate of the ul packet channel of UE 202.

In step 214, notify determined possibility maximum data rate to UE 202.UE 202 confirms to be used to send the data rate of grouped data within the scope of the possible maximum data rate of being notified, and in step 216, with determined data rate grouped data is sent to Node B 200.

Support the uplink physical channel of EUDCH service to comprise here: Dedicated Physical Data Channel (DPDCH), Dedicated Physical Control Channel (DPCCH), be used for the HSDPA service High-Speed Dedicated Physical Control Channel (HS-DPCCH), be used for the enhancing Dedicated Physical Data Channel (E-DPDCH) of EUDCH service and the enhancing Dedicated Physical Control Channel (E-DPCCH) that is used for the EUDCH service.

Just, in step 216, UE 202 sends E-DPCCH, and it provides the control channel of the frame format and the chnnel coding information of E-DPDCH channel, and sends grouped data through E-DPDCH.Here, E-DPCCH can also be used for the transmission of uplink data rate that UE 202 requires and transmitted power tolerance limit and for the demodulation of E-DPDCH by the transmission of the required pilot frequency information of Node B 200.

If in order to send the EUDCH grouped data as stated; Except existing physical channel; UE202 also sends independent physical channel, and the number of physical channels of then in up link, sending increases, thereby the peak value that causes up link to send signal increases average power ratio (PAPR).Generally speaking, the number of physical channels of sending simultaneously increases highly more, and then PAPR increases highly more.

Send signal and allow the distortion of adjacent channel leakage power than (ACLR) because PAPR increases to increase, so the compensation of the radio frequency among the UE (RF) power amplifier required power, its input power that reduces amplifier is to prevent foregoing problems.If UE carries out power back-off, then power back-off causes the received power at the receiver place in the Node B to reduce, thereby the error rate increase or the cell coverage area that cause receiving data dwindle.

Therefore, increase in order to prevent PAPR, UE is intended on the existing physical channel such as DPDCH, send EUDCH based on time-sharing format, rather than on independent physical channel, sends EUDCH.Yet, cause realizing the increase of complexity based on the processing of time-sharing format transmission EUDCH on existing physical channel.

Consider this problem, the WCDMA system has proposed a kind of method that is used for before physical channel being multiply by in the transmission of up link the OVSF code that satisfies mutually orthogonal property.In Node B, can distinguish the physical channel that multiply by the OVSF code.

Fig. 3 is the figure that is illustrated in the tree structure of the general OVSF code that uses in the WCDMA system.

With reference to figure 3, can in the computing of equation (3), generate the OVSF code simply at equation (1).

Equation (1)

C _ch，1，0＝1

Equation (2)

$\left[\begin{array}{c}{C}_{\mathrm{ch},\mathrm{2,0}}\\ C_{\mathrm{ch},\mathrm{2,1}}\end{array}\right]=\left[\begin{array}{cc}{C}_{\mathrm{ch},\mathrm{1,0}}& C_{\mathrm{ch},\mathrm{1,0}}\\ C_{\mathrm{ch},\mathrm{1,0}}& -C_{\mathrm{ch},\mathrm{1,0}}\end{array}\right]=\left[\begin{array}{cc}1& 1\\ 1& -1\end{array}\right]$

Equation (3)

$\left[\begin{array}{c}{C}_{\mathrm{ch},2^{(n+1)},0}\\ C_{\mathrm{ch},2^{(n+1)},1}\\ C_{\mathrm{ch},2^{(n+1)},2}\\ C_{\mathrm{ch},2^{(n-1)},3}\\ .\\ .\\ .\\ C_{\mathrm{ch},2^{(n+1)},2^{(n+1)}-2}\\ C_{\mathrm{ch},2^{(n+1)},2^{(n+1)}-1}\end{array}\right]=\left[\begin{array}{cc}{C}_{\mathrm{ch},2^n,0}& C_{\mathrm{ch},2^n,0}\\ C_{\mathrm{ch},2^n,0}& -C_{\mathrm{ch},2^n,0}\\ C_{\mathrm{ch},2^n,1}& C_{\mathrm{ch},2^n,1}\\ C_{\mathrm{ch},2^n,1}& -C_{\mathrm{ch},2^n,1}\\ .& .\\ .& .\\ .& .\\ C_{\mathrm{ch},2^n,2^n-1}& C_{\mathrm{ch},2^n,2^n-1}\\ C_{\mathrm{ch},2^n,2^n-1}& -C_{\mathrm{ch},2^n,2^n-1}\end{array}\right]$

As shown in Figure 3, the OVSF code is characterised in that between the code with same spread factor (SF) guarantees orthogonality.In addition, for two codes,, then between these two codes, obtain orthogonality if can not use equation (3) to generate code with big SF value from code with low SF value with different SF values.

To carry out its description as an example below.

For SF=4, C _{Ch, 4,0}=(1,1,1,1) and C _{Ch, 2,1}=(1 ,-1) quadrature, but and C _{Ch, 2,0}=(1,1) is non-orthogonal.

As another example, with SF=256 OVSF code and C _{Ch, 2,1}Compare in=(1,1), because from C _{Ch, 2,1}=(1,1) generates the OVSF code with SF=0～127, does not therefore guarantee orthogonality betwixt.Just,, use OVSF code, and when sending a plurality of physical channel simultaneously, should distribute the OVSF code, make and to guarantee orthogonality betwixt with low SF value owing to require higher data rate.

Even two physical channels use identical OVSF code; If but the I channel and the Q channel that pass through transmitter respectively send them; Then receiver can separate two physical channel signal and not have the phase mutual interference; And the physical channel signal that demodulation separated, this is because deliver the signal that on I channel and Q channel, sends through the carrier wave with 90 ° of phase differences.

As stated, number of physical channels, the power ratio between the physical channel of in up link, sending simultaneously, the I/Q channel allocation that is used for OVSF code and each physical channel of each physical channel are depended in the increase of up link PAPR.

In the WCDMA system that has used the EUDCH technology, if except uplink channel, also transmission is used to send the E-DPCCH and the E-DPDCH channel of EUDCH grouped data simultaneously, and then PAPR poorly increases.

Embodiment

Now, will be described in detail with reference to the attached drawings some preferred embodiments of the present invention.In the following description, for for simplicity, omitted the detailed description of knowing function and configuration here the sixth of the twelve Earthly Branches of incorporating into.

The present invention proposes OVSF code and I/Q method for channel allocation, it is used for minimizing the increase that up link is sent the PAPR of signal in the WCDMA system that supports the EUDCH data, services.Just; The present invention proposes OVSF code and the I/Q method for channel allocation optimized to such situation; That is, except existing physical channel, also send be used to send the EUDCH grouped data, as the E-DPCCH of control channel with as the E-DPDCH of data channel.In order to improve the EUDCH data rate and to minimize the increase of PAPR, the present invention proposes a kind of OVSF code and I/Q method for channel allocation, it is used to minimize PAPR and increases, and keeps the orthogonality between existing DPCCH, DPDCH and the HS-DPCCH simultaneously.

In existing Rel-5WCDMA standard, consider set up between UE and the Node B radio link during the maximum number of the sent DPDCH that confirms, realize being used for the OVSF code and the I/Q channel allocation of HS-DPCCH channel, so that reduce PAPR.

Therefore, to the Rel-5 physical channel, the maximum number of the DPDCH that can send in the consideration radio link and transmission/non-transmission of HS-DPCCH realize the OVSF code that is used for E-DPDCH and E-DPCCH and the I/Q channel allocation that propose in the present invention.In the EUDCH service, can send some E-DPDCH physical channels simultaneously, this is because they support high data rate to send.Yet usually, it is enough sending single E-DPCCH as physical control channel.

Just, send the PAPR increase of signal in order to reduce up link, the present invention considers to support EUDCH with having the back compatible property of WCDMA system now.Its reason is when mutually internally inconsistent, in initial call foundation or hand-off process, serious problems possibly take place when Node B because to the incompatibility of DPDCH and DPCCH standard and on version.

In other words; The present invention proposes a kind of OVSF code and I/Q method for channel allocation; It is optimized to the PAPR increase that minimizes EUDCH related physical channel, is kept for the existing Rel-5WCDMA standard as the DPDCH and the DPCCH of core uplink physical channel simultaneously.

First; Suppose through keeping the complete compatibility with existing Rel-5WCDMA system; In OVSF code and I/Q method for channel allocation; Existing uplink channel such as DPCCH, DPDCH and HS-DPCCH experiences as defined OVSF code and I/Q channel allocation in current standard; The present invention proposes a kind of OVSF code and I/Q method for channel allocation of optimizing to such situation, promptly send E-DPCCH and E-DPDCH in addition based on this supposition, it is the physical channel that is used to send the EUDCH grouped data.

The second, with considering that partial loss is with the compatibility of HS-DPCCH, keep and the situation of the compatibility of existing DPDCH and DPCCH simultaneously.In current Rel-5WCDMA standard, be one if can send the maximum number of DPDCH, then use OVSF code (256,64) on the Q channel, to send HS-DPCCH.In this case, because E-DPDCH can not use OVSF code (4,1) on the Q channel, thereby limited maximum EUDCH data rate.In order to address this problem, the present invention proposes the assignment of code rule of a kind of HS-DPCCH of being used for, E-DPCCH and E-DPDCH, so that allow E-DPDCH on the Q channel, to use OVSF code (4,1), and reduce the PAPR that UE sends signal.

The 3rd, in the Rel-6 standard, even consider independently situation of EUDCH, wherein in up link, do not send DPDCH and only send E-DPDCH.Therefore, the present invention is directed to EUDCH independence situation and proposed to be used for OVSF code and the I/Q channel allocation rule of HS-DPCCH.

In preceding method, be used for the I/Q channel of HS-DPCCH and the maximum number that the OVSF assignment of code depends on the DPDCH channel that can send, and the number of E-DPDCH channel does not influence the allocation rule that is used for HS-DPCCH.This is because always do not send E-DPDCH, just sends but have only when in the EUDCH of UE data buffer, having data.Therefore, according to PAPR, preferably, only consider that according to current standard DPDCH defines OVSF code and the I/Q channel allocation rule that is used for HS-DPCCH.

Fig. 4 illustrates the figure of the transmitter architecture of UE according to an embodiment of the invention.

1.DPCCH

According to existing Rel-99 and Rel-5 channel allocation rule, on the Q channel, OVSF code (256,0) is distributed to DPCCH.(256,0) equal OVSF code C shown in Figure 3 _{Ch, 256,0}Just, in Fig. 4, after the BPSK modulation, DPCCH multiply by OVSF code C _{Ch, 256,0}So that spread spectrum multiply by the transmission gain beta then _cβ _cThe speed or the required service quality scale of the data of being sent by network based UE are provided with.

The DPCCH signal is added to other channel signal that sends through the Q channel, multiply by scramble code S _{Dpch, n}, then through sending pulse shaping filter and RF level via antenna transmission.

2.DPDCH

According to the channel allocation rule that in existing standard, defines, if with SF _DPDCHThe expression DPDCH the SF value, then on the I channel with OVSF code (SF _DPDCH,SF _DPDCH/ 4) spread spectrum DPDCH.In Fig. 4, c _dExpression is used for the OVSF code of DPDCH.In the present invention, suppose when sending the physical channel relevant together, only send maximum DPDCH channels with the EUDCH service with DPDCH.

3.HS-DPCCH

In addition, this follows existing Rel-5 standard, and has only when in down link, realizing the HSDPA service and just be sent out.In Fig. 4, can find out, when in up link, only sending a DPDCH, on the Q channel with OVSF code (256,64) spread spectrum HS-DPCCH.

4.E-DPCCH

E-DPCCH; The physical control channel that is used for the EUDCH service; Send the buffer status of UE, perhaps send up-link transmit power, up-link transmit power tolerance limit and channel condition information (CSI), Node B needs them to come the estimating uplink channel condition.E-DPCCH sends the transformat and the resource indicator (E-TFRI) of the EUDCH service that is used on E-DPDCH, sending.

If with SF _E-DPCCHThe expression E-DPCCH the SF value, then on the I channel with OVSF code (SF _E-DPCCH, 1) and spread spectrum E-DPCCH.Give E-DPCCH with free way with OVSF code and I/Q channel allocation here.

In optional method, be different from the DPCCH that on the I channel, uses OVSF code (256,1) to send, E-DPCCH uses OVSF code (SF on the Q channel _E-DPCCH, 1).

In another optional method, when having set up HS-DPCCH, E-DPCCH is distributed to the Q channel when not setting up DPDCH.In this case, OVSF code (SF _E-DPCCH, 1) or (SF _E-DPCCH, SF _E-DPCCH/ 8) be suitable for E-DPCCH.

In another optional method, when not setting up DPDCH, can E-DPCCH be distributed to the Q channel, and no matter the foundation of HS-DPCCH/do not set up.In this case, OVSF code (SF _E-DPCCH, 1) or (SF _E-DPCCH, SF _E-DPCCH/ 8) be suitable for E-DPCCH.

Always such rule is available, and no matter the transmission of HS-DPCCH/do not send and the number of E-DPDCH channel.In this case, 8,16,32,64,128 and 256 for SF _E-DPCCHBe available, and consider the amount of information that on E-DPCCH, to send, confirm the SF that in fact will use _E-DPCCHValue.

Not setting up DPDCH and having set up under the situation of HS-DPCCH, even SF to I channel (256,1) _E-DPCCH=256, E-DPCCH can not be assigned with (SF _E-DPCCH, 1).Therefore, can not be to I channel (SF _E-DPCCH, 2) and to (SF _E-DPCCH, SF _E-DPCCH/ 8) distribute E-DPCCH.Just, realizing on the low PAR value, I channel (SF _E-DPCCH, 2) and to (SF _E-DPCCH, SF _E-DPCCH/ 8) distributing E-DPCCH is the most efficiently.Here, 32,64,128 and 256 for SF _E-DPCCHBe available.

With reference to figure 4, EUDCH transmit control device 402 receives the required control information of E-DPDCH through E-DPCCH sending node B.In Fig. 4, c _{Ch, SF, 1}Expression is used for the OVSF code of E-DPCCH, and multiply by the transmission code element, feasible corresponding channel and other physical channel quadrature.In addition, the same as other physical channel, the speed of the data of sending according to UE or the transmission gain beta that required levels of quality of service is provided with E-DPCCH _E-DPCCH

5.E-DPDCH

E-DPDCH is used for the Dedicated Physical Data Channel of EUDCH service, uses based on the schedule information that provides from Node B and determined data rate is sent the EUDCH grouped data.E-DPDCH not only supports BPSK but also supports QPSK and 8PSK, so that improve data rate, keeps the number of the spread-spectrum code of transmission simultaneously simultaneously.

As an example, get back to Fig. 4, E-DPDCH sends E-DPDCH1 and two channels of E-DPDCH2 simultaneously.Here, obvious is that the number of employed E-DPDCH physical channel depends on the transfer rate of EUDCH grouped data.In addition, EUDCH transmit control device 402 is confirmed the number and the SF value of the E-DPDCH channel of transmission simultaneously.

In other words, when data rate is low, use OVSF code to come spread spectrum E-DPDCH, make and to use an E-DPDCH to send it with big relatively SF value.Yet, when data rate is high, with SF _E-DPCCHValue is set to 4 or 2, makes to send the EUDCH grouped data through one or two E-DPDCH channel.

Just, EUDCH packet sender 404 is sent EUDCH through E-DPDCH1 and is sent data under the control of EUDCH transmit control device 402.Alternatively, where necessary even distribute E-DPDCH2 so that send.EUDCH data buffer 400 is the buffers that are used to store the EUDCH data that will be sent out.Under the control of EUDCH transmit control device 402, will arrive EUDCH packet sender 404 through the EUDCH data passes that the E-DPDCH channel sends.

The method that is used to E-DPDCH distribution OVSF code and I/Q channel of some embodiment according to the present invention will be described now.

First embodiment

First embodiment has proposed to be used to that E-DPDCH distributes OVSF code and I/Q channel and the method for not considering DPDCH.The method that is proposed can be through suitably adjusting E-DPDCH according to the EUDCH data rate minimum spreading gain value and the number of transmitting channel reduce PAPR.For the purpose of describing, consider the SF that is provided with based on data rate here, _E-DPDCH, will be this method sharing method A, method B and method C.

Method A is corresponding to the SF with E-DPDCH _E-DPDCHBe set to 4 or bigger situation.

1. an E-DPDCH channel is sent out

E-DPDCH1 uses OVSF code (SF _E-DPDCH, SF _E-DPDCH/ 2) send EUDCH through the Q channel and send code element.Here, 4,8,16,32,64,128 and 256 for SF _E-DPDCHBe available.In Fig. 4, c _Ed1Expression is used for the OVSF code of E-DPDCH1.The E-DPDCH1 that is assigned with the OVSF code by this way satisfies the orthogonality with other physical channel.Just, compare with the DPDCH that on the I channel, sends, when on the Q channel, sending E-DPDCH1, E-DPDCH1 can reduce its PAPR.

2. two E-DPDCH channels are sent out

SF as E-DPDCH 1 and E-DPDCH 2 _E-DPDCH Be 4 o'clock, use OVSF code (4,2) spread spectrum E-DPDCH1 and E-DPDCH2, send them simultaneously through Q channel and I channel respectively then.Just, E-DPDCH1 is distributed to the Q channel, and E-DPDCH2 is distributed to the I channel.Here, use to have 4 rank or higher modulation scheme such as QPSK, 8PSK and 16QAM, send the EUDCH grouped data.

For example; When using the QPSK modulation; With (± 1; ± 1) four kinds possibly made up the code element of sending through E-DPDCH1 and E-DPDCH2 transmission; And when using 8PSK; Eight kinds with ,

and (± 1, ± 1) possibly made up the code element of sending through E-DPDCH1 and E-DPDCH2 transmission.

Even if use SF _E-DPDCH=4 send E-DPDCH 1 and 2 two channels of E-DPDCH simultaneously, can not realize the EUDCH data rate expected, then might be through with SF _E-DPDCHBeing set to 2 allows with more high data rate transmission.Just, if the SF of E-DPDCH1 and E-DPDCH2 _E-DPDCHBe 2, then use OVSF code (2,1) to come spread spectrum E-DPDCH1 and E-DPDCH2, on Q channel and I channel, send them simultaneously respectively then.

With minimum spreading gain is that 4 situation is compared, when needs send some E-DPDCH physical channels by this way, and might be through the decreased number of the E-DPDCH channel that is sent is half the and significantly reduce PAPR.

The method category-B is similar to said method A, but distributes the OVSF code, makes when only sending E-DPDCH1, with SF _E-DPDCHBe set to minimum 2.

1. an E-DPDCH channel is sent out

When only sending E-DPDCH1,2,4,8,16,32,64,128 and 256 for SF _E-DPDCHBe available.Use OVSF code (SF _E-DPDCH, SF _E-DPDCH/ 2) E-DPDCH1 is distributed to the Q channel.

2. two E-DPDCH channels are sent out

Use OVSF code (2,1) to come spread spectrum E-DPDCH1 and E-DPDCH2, on Q channel and I channel, send them simultaneously respectively then.In this case, use to have 4 rank or higher modulation scheme such as QPSK, 8PSK and 16QAM, send the EUDCH grouped data.

Method C is similar to said method A, but distributes the OVSF code, if use SF even make _E-DPDCH=4 send E-DPDCH1 and two channels of E-DPDCH2 simultaneously, can not realize expecting the EUDCH data rate, then will be used for the SF of E-DPDCH1 _E-DPDCHBe set to 2, and will be used for the SF of E-DPDCH2 _E-DPDCHBe set to 4.

1. an E-DPDCH channel is sent out

As the SF that is used for E-DPDCH _E-DPDCHBe 4 or when bigger, use OVSF code (SF _E-DPDCH, SF _E-DPDCH/ 2) send EUDCH through the Q channel and send code element.Here, 4,8,16,32,64,128 and 256 for SF _E-DPCCHBe available.

2. two E-DPDCH channels are sent out

As the SF that is used for E-DPDCH1 and E-DPDCH2 _E-DPDCHBe 4 o'clock, use OVSF code (4,2) spread spectrum E-DPDCH1 and E-DPDCH2, send them simultaneously through Q channel and I channel respectively then.Even if send E-DPDCH1 and two channels of E-DPDCH2 simultaneously, can not realize expecting the EUDCH data rate, then will be used for the SF of E-DPDCH1 _E-DPDCHWith the SF that is used for E-DPDCH2 _E-DPDCHBe set to different values.

Just, as the SF that will be used for E-DPDCH1 _E-DPDCHBe set to 2, and will be used for the SF of E-DPDCH2 _E-DPDCHBe set at 4 o'clock, the data that then on channel separately, deliver experienced the BPSK modulation independently before being sent out.Therefore, before sending, respectively in the code element of using OVSF code (2,1) and (4,2) to come spread spectrum on E-DPDCH1 and E-DPDCH 2, to send on Q channel and the I channel.

In addition, in the time data rate can not being realized, will be used for the SF of E-DPDCH1 with aforementioned manner _E-DPDCHBe set to 2, and will be used for the SF of E-DPDCH2 _E-DPDCHBe set to 2, so that send.Just, use OVSF code (2,1) to come spread spectrum E-DPDCH2 and E-DPDCH1, on I channel and Q channel, send them simultaneously respectively then.In this case, can use to have 4 rank or more modulation scheme such as QPSK, 8PSK and the 16QAM of high-order, send the EUDCH grouped data.

Method D is such method, and it is used for when not sending DPDCH and HS-DPCCH, even perhaps when sending HS-DPCCH but use from OVSF code (4; During the OVSF code that 0) generates; OVSF code (4,1) is distributed to additional E-DPDCH, to improve the EUDCH throughput.This is because only send HS-DPCCH for the HSDPA service.In addition, this is that DPDCH only is used for the transmission of signaling information once in a while, and possibly not be sent out At All Other Times because when not having the data that will on DPDCH, send.In the WCDMA standard after Rel-5, there is the possible situation of not setting up DPDCH and only setting up E-DPDCH.

Two or still less the E-DPDCH channel be sent out

Can use preceding method A, method B or method C.

2. three E-DPDCH channels are sent out

When not sending HS-DPCCH, use OVSF code (4,1) to send the E-DPDCH3 channel through the Q channel.

Alternatively, when not sending DPDCH, use OVSF code (4,1) to send the E-DPDCH3 channel through the I channel when sending HS-DPCCH.

3. four or more E-DPDCH channels are sent out

I channel and Q channel all use OVSF code (4,1) to be used for sending.When OVSF code (4,1) is not used by DPDCH and HS-DPCCH, use it.

In other words, when neither sending HS-DPCCH and also do not send DPDCH, use OVSF code (4,1) respectively, send the third and fourth E-DPDCH channel through I channel and Q channel.Even ought not set up DPDCH, and when using the OVSF code that generates from OVSF code (4,0) to send HS-DPCCH, in I and Q channel, never use OVSF code (4,1).Therefore, might use OVSF code (4,1) on the I/Q channel, to send the third and fourth E-DPDCH channel.
