Specific embodiment

Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art The all other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.

Fig. 1 is the flow chart of signaling method embodiment one of the present invention.The embodiment of the present invention provides a kind of signal and sends Method, this method can be performed by sender unit, which can be integrated in base station equipment or user equipment.Such as Fig. 1 Shown, this method includes：

S101, modulation symbol sequence and the first spreading code set are obtained.

S102, using each spreading code in the first spreading code set, respectively to each spread spectrum in the first spreading code set The modulation symbol sequence transmitted on the corresponding code channel of code is spread, and obtains spread-spectrum signal.

S103, Scrambling Operation is carried out to spread-spectrum signal, obtains echo signal, the spreading rate of scrambler is Y in Scrambling Operation.

S104, echo signal is sent.

Wherein, the first spreading code set is the subset of the second spreading code set, in any one spreading code of the first spreading code set, from First chip starts, and is one group per adjacent N number of chip, and the corresponding chip value of N number of chip in every group is identical, wherein, N =X/Y, X are the spreading rate of any spreading code in the second spreading code set, and Y is the corresponding spreading rate of echo signal.For example, N Value is 2 positive integer power.

The spreading code can be described as channel code (Channelization Code) again.Illustrate this by taking UMTS as an example below The signaling method that inventive embodiments provide, but the present invention is not limited.Here, due to concentrating spread spectrum using the first code channel The bandwidth of echo signal that code spread spectrum obtains, for using spreading code spread spectrum obtains in second code trace gather the N of the bandwidth of signal points One of, therefore, can N be referred to as zoom factor.In umts, the second spreading code set is OVSF all-key trees, and the first spreading code set is The subcode tree of OVSF all-key trees.

Existing UMTS is using Orthogonal Variable Spreading Factor OVSF (Orthogonal Variable Spreading Factor, letter Claim：OVSF) the channel code set that all-key tree is taken as realizes the spread spectrum and code division multiplexing of modulation symbol sequence.Wherein, OVSF all-key tree construction examples are as shown in Figure 2：SF is spreading factor (Spreading Factor), spreading factor and symbol speed Rate is multiplied to obtain chip (chip) rate, and as SF=1, spreading rate is identical with character rate, at this point, code channel C_ch,1,0In Channel code is (1), i.e., represents data-signal " 1 " with encoded signal " 1 ", obtain spread-spectrum signal " 1 "；As SF=2, chip speed Rate is 2 times of character rate, at this point, code channel C_ch,2,0In channel code for (1,1), i.e., represent data with encoded signal " 11 " Signal " 1 " obtains spread-spectrum signal " 11 ", similarly, code channel C_ch,2,1In channel code for (1, -1), i.e., with encoded signal " 1-1 " It represents data-signal " 1 ", obtains spread-spectrum signal " 1-1 "；And so on, obtain the channel code and spread spectrum when SF takes other values Signal no longer repeats one by one herein.Specifically, the OVSF all-keys tree used in UMTS is fixed in detail in 3GPP TS 25.213 Justice.

It has been observed that in the spreading code of upper half code tree shown in Fig. 2, i.e. code channel C_ch,2,0And its in subtree, each spread spectrum Two chip values adjacent chip being divided into two-by-two in one group, every group of code be it is the same, the two are identical Sequential chips that regards the new chip being doubled on a time as, then the spreading code in upper half code tree can regard what SF halved as The new spreading code that chip delay is elongated.Equally, the spreading rate of the new spreading code is the spreading rate of former spreading code Half.

Therefore, in umts, pass through restricting user equipment (User Equipment, abbreviation：UE) and base station equipment only Use is with C_ch,2,0For the subcode tree of root node, still echo signal, the echo signal are obtained using the processing module of 3.84Mcps Equivalent spreading rate halve.It means that the first spreading code set used only by limitation is in C_ch,2,0For root section In the subcode tree of point, handled using full bandwidth, you can equally to obtain the spread spectrum that spreading rate halves (equivalent bandwidth halves) Signal.

The spread-spectrum signal that this spreading rate halves is subjected to Scrambling Operation, the scrambler that the Scrambling Operation uses is chip speed Rate is the scrambler sequence of Y.The echo signal obtained after scrambling is sent, is sent for example, base station equipment is sent to UE or UE To base station equipment, etc..

It is the example of N=2 above, wherein OVSF all-keys tree construction is as shown in Figure 2.But the present invention is not excluded for using it His orthogonal spectrum expansion code tree result.Correspondingly, it is only necessary to which each spreading code in limitation spread spectrum subset of codes divides chip two-by-two After group, the identical echo signal that can obtain equivalent N=2 of chip in every group.

Similarly, as long as in the processing of UMTS, limitation only Jin Shiyong is with C_ch,4,0It, then can be with for the subcode tree of root node Equally (equivalent spreading rate is 1/4*UMTS spreading rates to the echo signal of acquisition scale factor N=4；Then, using 1/4 The scrambler scrambling of spreading rate, you can realize 1/4 small bandwidth communication.

Therefore, based on above-mentioned theory, the embodiment of the present invention provides a kind of signaling method, realizes that small bandwidth system is led to Letter.

In embodiments of the present invention, the first spreading code set is to be set in advance in base station equipment and/or UE according to actual demand In, for example, the first spreading code set is C shown in Fig. 2_ch,2,0Or C_ch,4,0Etc.；Or, radio network controller (Radio Network Controller, referred to as：RNC it) is indicated by high-level signaling.Then, using in first spreading code set Each spreading code, respectively to the modulation symbol sequence that is transmitted on the corresponding code channel of each spreading code in the first spreading code set into Row spread processing obtains spread-spectrum signal, and is scrambled the (spreading rate of the scrambler used during the scrambling to the spread-spectrum signal Should be corresponding with small bandwidth, be the 1/N of UMTS scrambled chip rates), to obtain signal bandwidth as UMTS system signal bandwidth 1/N Echo signal.

What if the first spreading code set was indicated for RNC by high-level signaling, before the first spreading code set is obtained, this method It can also include：The high-level signaling that RNC is issued is received, the first spreading code set is obtained by the high-level signaling.

It should be noted that in uplink communication, spreading code (i.e. channel code) is believed for distinguishing the different of same user Road, scrambler are used to distinguish user；In downlink communication, spreading code is assigned to the different user in same cell, and scrambler is used for Distinguish different cells.Therefore, signaling method provided in an embodiment of the present invention is related to spread processing and scrambling processing, with right User and subscriber channel (or cell and community user) are distinguish.

Wherein, the OVSF all-keys tree in above-described embodiment is the code tree set used described in UMTS, is defined in 3 gpp, The subcode tree of the OVSF all-keys tree is with C_ch,N,0Subcode tree for root node.

In the definition of TS25.213, the construction of OVSF all-key trees follows following criterion：

C_ch,1,0=1

Fig. 3 is the flow chart of signaling method embodiment two of the present invention.Signalling provided in an embodiment of the present invention Method can also further include on the basis of embodiment as shown in Figure 1：

S301, echo signal is filtered, which can include root cosine filtering process and radio frequency is filtered Wave processing, the bandwidth of filtering process is Y.

Wherein, root cosine (Root Raised Cosine, abbreviation：RRC) filtering process and radio frequency (Radio Frequency, referred to as：RF) filtering process.For example, in umts, by taking N=2 as an example, after the step, 2.5 can be obtained The UMTS signals of million (M) radio frequency bandwidths.

The spread-spectrum signal of acquisition is passed through RRC wave filters and RF wave filters, you can the small band after being filtered by the step Bandwidth signals.Wherein, above-mentioned filtering process can reduce the band outward leakage of echo signal.

As the concrete application embodiment of the present invention, it can limit and use in echo signal sends and receives The code channel that can be used in OVSF all-key trees is the corresponding code channel of each spreading code in the first spreading code set, so as to reach The purpose of simplify control signaling.

As the embodiment of simplify control signaling, system (such as S-UMTS) can only use respectively to expand in the first spreading code set The corresponding code channel of frequency code based on this feature, simplifies the control signaling of S-UMTS, to save control signaling expense.

With high-speed slender body theory (High Speed Downlink Packet Access, abbreviation：HSDPA for), For UMTS, the scheduling of HSDPA needs to support the scheduling of the SF16 code channels (HS-PDSCH code channels) of complete 15 code channel, wherein HS-PDSCH represents high-speed physical downlink shared channel (HS-PDSCH), English：High Speed Downlink Physical Channel, because This, in High-Speed Shared Control Channel (High Speed Shared Control Channel, the abbreviation of downlink：HS-SCCH in) The dispatch of transmission (is used to indicate the code channel collection information of HSDPA, modulation system, code check, RV versions and HARQ process numbers Signaling) it is required to indicate the code channel of the arbitrary continuation in 15 code channels, therefore, dispatch is provided in 3GPP TS 25.212 Part I parts channel code trace gather (Channelization CodeSet, referred to as：CCS) information field needs 7 bits Position (bit) indicates the initial position of scheduled HS-PDSCH and code channel number.With the scheduling of Type1 types in TS 25.212 For signaling, agreement regulation represents CCS information with 7 bits.By the 7bit, it can represent arbitrary in 15 code channel set Continuation code road subset.

In the embodiment of the present invention, signaling method can also include：Instruction information is sent, instruction information, which is used to indicate, to be made HSDPA is sent with the corresponding code channel of one or more of the first spreading code set spreading code, indicates the CCS domains in information for referring to Show that the corresponding code channel of the first spreading code set concentrates arbitrary continuation code channel subset.The first spread spectrum is used only in base station equipment and user equipment The corresponding code channel of code collection sends HSDPA, therefore, can reduce the bit that CCS domains are included in the dispatch of downlink based on this Position.

Specifically, by taking the S-UMTS of N=2 as an example, for the S-UMTS for having used the first spreading code set spread spectrum, at this moment C in OVSF all-key trees can only be used_ch,2,0For the subcode tree of root node, then for the code channel of SF16, only expand first Frequency code concentrates the corresponding code channel { C of each spreading code_ch,16,0,C_ch,16,1,……,C_ch,16,6,C_ch,16,7Can just be used.Based on this, For the S-UMTS of N=2, only need 5 bits that can represent appointing in the corresponding code channel of each spreading code in the first spreading code set Meaning continuation code road subset, corresponding to the dispatch of 1 types of Type, each bit and the first spreading code set of instruction in CCS domains The code channel number of corresponding code channel concentration arbitrary continuation code channel subset and the relationship of initial position are：

For the first two bit x in CCS domains_ccs,1And x_ccs,2, wherein, x_ccs,1For most significant bit (Most Significant Bit, referred to as：MSB)：x_ccs,1,x_ccs,2=min (P-1,7-P)；

Wherein, x_ccs,1Represent the first bit in CCS domains, x_ccs,2Represent the second bit in CCS domains, P be the indicated The corresponding code channel number of continuation code line collection in one spreading code set；

If it is determined that using quaternary quadrature amplitude modulation (16QAM) and four phase shift keying (Quadrature Phase Shift Keying, referred to as：During one in QPSK), other bits and the company in the first spreading code set of instruction in CCS domains The relationship of the corresponding code channel number of continued code line collection and initial position is：

Wherein, x_ccs,3Represent third bit in CCS domains, x_ccs,4Represent the 4th bit in CCS domains, x_ccs,5Represent CCS 5th bit in domain, O are the initial position of the corresponding code channel of continuation code line collection in the first spreading code set of instruction,It represents to the downward rounding of the result of calculation of P/4；

Further, using four phase shift keying (Quadrature Phase Shift Keying, abbreviation：QPSK) and During one in quaternary quadrature amplitude modulation (16QAM) and octal system quadrature amplitude modulation (64QAM), when using 16QAM, x_ccs,5=0；When using 64QAM, x_ccs,5=1.

Fig. 4 is the flow chart of signaling method embodiment three of the present invention.The embodiment of the present invention provides a kind of signal and sends Method, this method can be performed by sender unit, which can be integrated in RNC or other network side equipments.Such as Fig. 4 Shown, this method includes：

S401, according to the original bandwidth of system and target bandwidth, determine the first spreading code set.

S402, high-level signaling is issued, high-level signaling is used to indicate the first spreading code set.

Wherein, target bandwidth is equal to the corresponding spreading rate Y of echo signal, and original bandwidth is equal to the second original expansion of system The spreading rate X of any spreading code of frequency code concentration, subset of first spreading code set for the second spreading code set, and described first It is one group per adjacent N number of chip, and N number of in every group since first chip in any one spreading code of spreading code set The corresponding chip value of chip is identical, N=X/Y.Optionally, N values are 2 positive integer power.

The inventive embodiments are used to illustrate the first spreading code set in the acquisition of network side equipment and issue.Wherein, first expands Frequency code collection can also be handed down to base station equipment or user equipment by other forms, what the present invention was not carried with above-mentioned high-level signaling Form is limited.

Optionally, above-mentioned second spreading code set is OVSF all-key trees, and the first spreading code set is the son of the OVSF all-keys tree Code tree.

On the basis of the above, the system for the spreading code in the first spreading code set has been used to be spread, such as UMTS For, the corresponding code channel of one or more spreading code, hair in the first spreading code set can only be used by sending the transmitting terminal of echo signal Sending end come the data of the implicit instruction UE under cross-carrier scheduling scenario can be that UMTS is used on first carrier based on this feature What signal was sent, still sent on a second carrier with echo signal.For receiving terminal, then it can be based on this feature and detect Transmitting terminal is still to use echo signal transmission data on a second carrier with UMTS signal transmission datas from first carrier.I.e. In cross-carrier scheduling (Cross-Carrier Scheduling), each spreading code in the first spreading code set can be used corresponding Code channel is dispatched on first carrier (main carrier) to distinguish or is dispatched on the second carrier wave (secondary carrier).

Wherein, cross-carrier scheduling is the telescopic Universal Mobile Communication System of dependent (Scalable UMTS, abbreviation：S- UMTS a kind of typical scheduling mode), dependent S-UMTS represent that S-UMTS and UMTS is used cooperatively.Due to the band of S-UMTS It is wide smaller, therefore, when transmitting same quantity of data, if still retaining the broadcast channel of the guarantee covering in original UMTS (Broadcast Channel, referred to as：BCH) and ensure covering (support measure) P-CPICH channels, then these controls The code channel and power overhead of signaling will be very big, so as to limit the handling capacity of small bandwidth system significantly.Therefore, dependent S-UMTS quilts Iing is proposed --- the S-UMTS on the second carrier wave (secondary carrier) only sends high-speed slender body theory (High Speed in downlink Downlink Packet Access, referred to as：HSDPA) data, it is corresponding for scheduling the second carrier wave (secondary carrier) HSDPA Dispatch still sent on first carrier (main carrier), the tune of transmission need to be distinguished on first carrier (main carrier) at this time Data scheduled in degree signaling are to send in main carrier or sent in secondary carrier.

A kind of mode is using High-Speed Shared Control Channel (High Speed Shared Control Channel, letter Claim：HS-SCCH) occupied code channel information come implicitly indicate user equipment be on main carrier scheduling or secondary carrier up-regulation Degree.This method that carrier wave where HS-PDSCH is indicated with HS-SCCH code channel informations may cause to being dispatched on main carrier Limitation, such as, it is assumed that non-multi input multi output (Multiple Input Multiple Output, abbreviation are dispatched on main carrier： MIMO) user equipment, it is known that the parity using HS-SCCH code channels has been required in existing protocol come distinguish 64QAM and 16QAM, then be re-introduced into the first spreading code set (such as { 0,1 } is main carrier, and { 2,3 } are secondary carrier) to distinguish scheduling carrier wave Words may generate limitation to the user equipment dispatched on main carrier.For example, for one scheduling 16QAM on main carrier User equipment when, then be only capable of dispatching on carrier wave 0, if at this point, there are two such user equipment, scheduling may be produced It is raw to influence.Such case in main carrier heavier loads or code-limited when more (such as R99 speech businesses), HS-SCCH codes In the case that road is resource-constrained, the influence to scheduling is particularly evident.

The present invention provides a solution to above-mentioned scheduling defect, that is, the S- of the first spreading code set configuration has been used in combination UMTS features itself, the data scheduled in dispatch on implicit instruction main carrier be sent on main carrier or auxiliary It is sent on carrier wave.

In embodiments of the present invention, by taking downlink HSDPA as an example, the S-UMTS that the first spreading code set is configured has been used to be used only (data correspondence is in the first spreading code set for the corresponding channel transmission HSDPA data of one or more spreading code in first spreading code set In send on HS-PDSCH channels corresponding to each spreading code).

Specifically, in a kind of realization method, echo signal is telescopic UMTS signals.

S502, the corresponding dispatch of HSDPA data is sent to user equipment on first carrier, to indicate user equipment Corresponding HSDPA data are received according to UMTS signals or scalable UMTS signals.

Wherein, scalable UMTS signals are obtained after being spread by the spreading code in the first spreading code set, UMTS letters Number obtained after being spread by the spreading code in the second spreading code set, the first spreading code set is the son of the second spreading code set Collect, be one group per adjacent N number of chip, and every group since first chip in any one spreading code of the first spreading code set The interior corresponding chip value of N number of chip is identical, wherein, N=X/Y, X are the chip speed of any spreading code in the second spreading code set Rate, Y are the corresponding spreading rate of echo signal.

For the user equipment dispatched on first carrier, UMTS signals are sent to user equipment on first carrier, The corresponding HS-PDSCH of UMTS signaling bearer HSDPA data, can include：In second at least one spread spectrum of spreading code centralized distribution The corresponding code channel of code is at least wrapped as the HS-PDSCH for sending HSDPA data, the HS-PDSCH for sending HSDPA data Include a HS-PDSCH other than the corresponding code channel of each spreading code in the first spreading code set, on first carrier to Family equipment sends HSDPA data.That is, other than distribution is comprising the corresponding code channel of each spreading code in the first spreading code set HS-PDSCH to the user equipment dispatched on first carrier, and on first carrier send UMTS signals set to the user It is standby.

For the user equipment dispatched on a second carrier, in a kind of realization method, on a second carrier to user equipment Send scalable UMTS signals, the corresponding HS-PDSCH of scalable UMTS signaling bearers HSDPA data, it may include：Obtain first Spreading code set；In the corresponding code channel of first at least one spreading code of spreading code centralized distribution as sending HSDPA data HS-PDSCH；The HS-PDSCH of HSDPA data is carried on scalable UMTS signals, and passes through the second carrier wave and is sent to user and set It is standby.

When sending scalable UMTS signals to user equipment on a second carrier, sent on first carrier to user equipment The corresponding dispatch of HSDPA data, can include：Dispatch is carried on to the high speed Compliance control sent on first carrier Channel (High Speed Shared Control Channel, referred to as：HS-SCCH user equipment, dispatch are sent in) Comprising instruction information, instruction information, which is used to indicate HSDPA data, to be carried on the second carrier wave.

That is, base station equipment in cross-carrier scheduling, sets the user dispatched on first carrier (main carrier) Standby, code channel collection resource of the distribution comprising the HS-PDSCH other than the corresponding code channel of each spreading code in the first spreading code set is used for To user equipment transmission data on first carrier (main carrier)；The user dispatched on the second carrier wave (secondary carrier) is set It is standby, the code channel resource of HS-PDSCH of the corresponding code channel of each spreading code in the first spreading code set is only distributed in the second carrier wave To user equipment transmission data in (secondary carrier), and pass through in the corresponding HS-SCCH sent on first carrier (main carrier) Instruction information indicate that the data are sent on the second carrier wave (secondary carrier).

Wherein, instruction information can include implicit instruction information and display instruction information, and implicit instruction information includes passing through The corresponding occupied code channel informations of HS-SCCH are indicated.

By taking the S-UMTS of N=2 as an example, spread according to the first spreading code set, i.e., using only half in OVSF all-key trees Code channel resource, it is assumed that on small carrier wave only have { C_ch,16,0,C_ch,16,1,………C_ch,16,6,C_ch,16,7The code channel of SF16 can be with It uses, based on this point, following rule may be used：

For the user equipment dispatched on first carrier (main carrier)：

1) base station equipment is distributed as far as possible comprising code channel { C_ch,16,8,C_ch,16,9,……,C_ch,16,14,C_ch,16,15HS- PDSCH resources give first carrier (main carrier) user equipment.Once user equipment, which detects, in this way distributes to the user equipment HS-PDSCH resources in contain { C_ch,16,8,C_ch,16,9,……,C_ch,16,14,C_ch,16,15HS-PDSCH code channels in it is arbitrary One, the user equipment can confirm that be scheduled to its HSDPA data sends on first carrier (main carrier).This When, there is no any restrictions to the occupied code channel of the corresponding dispatch of the user equipment.

If 2) since limiting factors, the base station equipments such as burst service (burst traffic) must be SF16's {C_ch,16,0,C_ch,16,1,……,C_ch,16,6,C_ch,16,7Code channel collection in distribution resource, i.e., can not distribute { C_ch,16,8, C_ch,16,9,……,C_ch,16,14,C_ch,16,15In resource, then at this moment user equipment can not come true from the CCS domains of dispatch Surely the data for being scheduled to user equipment are sent on which carrier wave, and in this case, base station equipment needs to use HS- The occupied code channel informations of SCCH indicate the data for being scheduled to user equipment are sent on which carrier wave, such as numbering HSDPA data scheduled in the dispatch that is sent on the HS-SCCH code channels of { 2,3 } are sent out on the second carrier wave (secondary carrier) It send, the HSDPA data scheduled in dispatch sent on the HS-SCCH code channels that number is { 0,1 } are (main in first carrier Carrier wave) on send.

In practice for above situation 2), base station equipment can essentially be avoided by dispatching, such as first carrier It is less than the dispatching user facility of 7 code channels on (main carrier) in { C_ch,16,8,C_{Ch, 16,9,}……,C_ch,16,14,C_ch,16,15In, and it is big In the dispatching user facility of 7 code channels, consider comprising { C_ch,16,0,C_ch,16,1,……,C_ch,16,6,C_ch,16,7Code channel collection, in this way At least still there is code channel to be present in { C_ch,16,8,C_ch,16,9,……,C_ch,16,14,C_ch,16,15In, it is possible to it is the to distinguish this One carrier wave (main carrier) user equipment.

For the user equipment dispatched on the second carrier wave (secondary carrier)：

The HS-PDSCH code channels that base station equipment is distributed for it are in { C_ch,16,0,C_ch,16,1,……,C_ch,16,6,C_ch,16,7In.This When, in order to be distinguished with the user equipment that may be distributed on these HS-PDSCH code channels on first carrier (main carrier), need It is indicated in the dispatch to be sent on specific HS-SCCH code channels.

By above method, the user equipment sent on first carrier (main carrier) is scheduled in for data, it is adjusted The code channel limitation of degree signaling can substantially reduce, as long as having in assigned code channel positioned at { C_ch,16,8,C_ch,16,9,……, C_ch,16,14,C_ch,16,15Code channel, then do not need to be to indicate its HSDPA data according to the explicit or implicit information of dispatch It is sent on first carrier (main carrier)；The user equipment sent on second carrier wave (secondary carrier) is scheduled in for data, Then still indicate that corresponding HSDPA data are (auxiliary in first carrier or the second carrier wave using special explicit or implicit information Carrier wave) send.The implicit information indicating means includes the use of the occupied code channel informations of HS-SCCH and is indicated.

Method for HS-SCCH code channel collection information is used to carry out implicit instruction, it can be seen that distribution is for the second carrier wave (secondary carrier) instruction HS-SCCH code channels collection still can indicate on first carrier (main carrier) UE scheduling, as long as this first There are { C in the HS-PDSCH of user equipment dispatched on carrier wave (main carrier)_ch,16,8,C_ch,16,9,……,C_ch,16,14, C_ch,16,15Code channel.
