Abstract

The invention provides a conflict detection method, network side equipment and user equipment (UE). The conflict detection method comprises the following steps: if the UE does not transmit uplink data in the establishing process of a high-speed dedicated physical control channel (HS-DPCCH), the UE generates uplink construction data which comprise identification information used for identifying the UE; and the UE transmits the uplink construction data to the network side equipment through an enhanced-dedicated physical data channel (E-DPDCH), so that the network side equipment identifies the UE according to the identification information in the uplink construction data to finish conflict detection on resources used by the UE. According to the technical scheme of the conflict detection method, the network side equipment can identify the UE which does not transmit the uplink data in the establishing process of the HS-DPCCH so as to finish the conflict detection, a large amount of UE are allowed to establish the HS-DPCCH at the same time, and the delay time of the UE for establishing the HS-DPCCH is shortened.

Description

Collision detection method, network equipment and subscriber equipment

Technical field

The present invention relates to mobile communication technology, relate in particular to a kind of collision detection method, network equipment and subscriber equipment.

Background technology

At third generation partner program (3rd Generation Partnership Project, 3GPP) Wideband Code Division Multiple Access (WCDMA) (Wide-band Code Division Multiple Access, WCDMA) in the R7 version, in order to improve subscriber equipment (User Equipment, UE) at sub-district-forward access channel (CELL Forward Access Channel, CELL-FACH) state and sub-district-paging channel (CELL Paging Channel, CELL-PCH) downstream data rate under the state has been introduced this characteristic of enhancing CELL-FACH.By strengthening this characteristic of CELL-FACH, UE can be from high speed descending sharing channel (High Speed Downlink Shared Channel, HS-DSCH) downlink data receiving under CELL-FACH and CELL-PCH state.But, in the R7 version, the upstream data of UE still passes through Physical Random Access Channel (the Physical Random Access Channel of R99 version, PRACH) transmission can not provide to mix automatically to retransmit (Hybrid Automatic Repeat Request, HARQ) feedback, therefore, network side adopts the mode of blind re-transmission to send descending HS-DSCH, promptly do not feed back decision according to affirmation/non-affirmation (ACK/NACK) of UE and retransmit, but fixing repeating is transmitted several times.

In 3GPP WCDMA R8 version, it is special uplink channel (the Enhanceduplink DCH that public (common) strengthens that UE can compete the ascending resource that obtains, E-DCH) resource, when network side sends descending HS-DSCH data, UE can be by shared common E-DCH resource to the HARQ feedback information of network side transmission at descending HS-DSCH data, the mode that makes network side not re-use blind re-transmission sends descending HS-DSCH, has improved the utilance of downlink resource.

But, because current type of service is many, having only downlink data to pass through the HS-DSCH channel in a period of time for some business sends, and do not need UE that up data are provided, this moment, UE just can not compete common E-DCH resource, also just can not provide HARQ feedback information at descending HS-DSCH data to network side by common E-DCH resource, at this moment network side still can only adopt the mode of blind re-transmission to send descending HS-DSCH, causes efficiency of transmission lower.In order to address this problem, Dedicated Physical Control Channel (the standalone HS-DPCCH of independent HS-DSCH has been proposed to be called in 3GPP WCDMA R11 version, the English of HS-DPCCH is: scheme Dedicated Physical Control Channel for HS-DSCH), promptly once only allow a UE who does not have upstream data to send to set up the HS-DPCCH channel, will be carried on the HS-DPCCH channel at the HARQ feedback information of descending HS-DSCH data and send to network side.

Because network side can't identify UE by HS-DPCCH, so in standalone HS-DPCCH scheme, carry out HS-DPCCH and set up and avoid a plurality of UE to carry out simultaneously having used same asset when HS-DPCCH sets up and on this resource, cause conflict by once only triggering a UE.But, carry out HS-DPCCH and set up because network side only triggers a UE in a period of time, just can trigger other UE after having only by the time the HS-DPCCH of this UE to set up to finish and set up, it is longer to cause UE to carry out the time delay that HS-DPCCH sets up.

Embodiment

For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.

The flow chart of the collision detection method that Fig. 1 provides for one embodiment of the invention.As shown in Figure 1, the method for present embodiment comprises:

Step 101, UE receive the trigger message that network equipment sends, and carry out HS-DPCCH according to the trigger message that receives and set up.

The UE of present embodiment is meant that the trigger message according to network side carries out HS-DPCCH foundation, and is carrying out HS-DPCCH sets up does not have upstream data to send in the process UE, but is not limited thereto.

In the present embodiment, the triggering UE of UE reception network equipment transmission carries out the trigger message that HS-DPCCH sets up.UE can obtain the signature and the access slot of up access after receiving trigger message, initiate the process that inserts at random.The signature of the up access that UE obtains may be the signature that UE selects in available signature at random, also may be the access signature of network equipment appointment, and for example: network equipment can be specified available signature at the HS-SCCH channel.Wherein, the access slot of the UE up access of obtaining is the time slot that UE selects in available time slot at random.

When network equipment detects the access of UE and but the resource time spent is arranged, network equipment is in AICH Acquisition Indication Channel (Acquisition Indication Channel, AICH) indication UE uplink resources available.This ascending resource may be acquiescence (default) resource of the signature correspondence used of UE, and also may be network equipment catches indication (Enhanced AI, EAI) Zhi Shi resource by what strengthen.Wherein, the ascending resource of network equipment indication UE comprises that mainly UE carries out up-downgoing and sends employed sign indicating number information, described sign indicating number information comprises E-DCH Dedicated Physical Control Channel (E-DCH Dedicated Physical DataChannel, E-DPCCH), the E-DCH absolute grant channel (E-DCH Absolute Grant Channel, E-AGCH) etc.Then, UE adopt the ascending resource of network equipment indication to begin to send Dedicated Physical Control Channel (Dedicated Physical Control Channel DPCCH), and can send HS-DPCCH, simultaneously the HARQ feedback information is carried on the HS-DPCCH channel.

If step 102 UE sets up and do not have upstream data to send in the process carrying out HS-DPCCH, UE generates up construction data, described up construction data comprise unique in sub-district, UE place the identification information of sign UE.

Wherein, in the process that the UE of present embodiment inserts at random, the UE that has a plurality of other UE and present embodiment inserts simultaneously at random, and network equipment may be given the identical ascending resource of UE indication of a plurality of other UE and present embodiment, transmit from DPCCH so, these UE will adopt identical ascending resource to send, and will clash this moment on this resource.Can be successful for the up process of transmitting that guarantees each UE, network equipment need solve problem by collision detection.

Wherein, collision detection is meant that network equipment detects same resource and whether used simultaneously by a plurality of UE, and with the unique process that licenses to a UE of this resource.Use the situation of same resource simultaneously for the detected a plurality of UE that have upstream data to send of network equipment, network equipment can identify each UE that uses same resource simultaneously according to the sign of the UE in the upstream data that detects each UE transmission, so can be with unique one of them UE that licenses to of this resource.But, for carrying out HS-DPCCH sets up does not have upstream data to send in the process UE, network equipment can't identify this UE by HS-DPCCH, HS-DPCCH sets up does not have upstream data to send in the process UE is carried out in existence among a plurality of UE that use same resource simultaneously if die, and then network equipment can't be finished the collision detection to this resource.

For this reason, carrying out HS-DPCCH sets up does not have upstream data to send in the process a kind of data of UE oneself structure in the present embodiment, it is up construction data, by up construction data carry can be in sub-district, UE place the identification information of unique identification UE itself so that network equipment can identify present embodiment according to the identification information in the up construction data carrying out HS-DPCCH sets up does not have upstream data to send in the process UE.

Step 103, UE are by E-DCH Dedicated Physical Data Channel (E-DCH Dedicated Physical Data Channel, E-DPDCH) up construction data is sent to network equipment, so that network equipment identifies UE to finish the collision detection of the resource that UE is used according to the identification information in the up construction data.

After the UE of present embodiment generation comprises the up construction data of the identification information that can identify its identity, it is sent to network equipment as a kind of upstream data by E-DPDCH, thereby make network equipment carry out HS-DPCCH sets up does not have upstream data to send in the process UE, and then finish the collision detection of the resource that the UE to present embodiment uses based on what the identification information in this up construction data identified present embodiment.

Wherein, described network equipment is meant that to the collision detection of the resource of the UE use of present embodiment network equipment detects the employed resource of UE that whether has a plurality of UE to use present embodiment simultaneously, and with the unique process that licenses to certain UE of this resource.The resource of using with present embodiment UE is example, network equipment can detect the resource that the UE of present embodiment is given in indication, if on this resource, both detected the up construction data of the UE of present embodiment, detect upstream data or up construction data that other UE send again, network equipment determines that the UE that this UE that is authorized to may be a present embodiment also may be other UE with unique one of them UE that licenses to of resource of the UE use of present embodiment; Otherwise network equipment uses the unique UE that licenses to present embodiment of resource with the UE of present embodiment.To be network equipment indicate ascending resource to the UE of present embodiment at the AICH channel to the resource that the UE of present embodiment uses.

Preferably, network equipment can be the base station, but is not limited thereto.For example, network equipment also can be radio network controller (Radio Network Controller, RNC).

In the present embodiment, if UE sets up and does not have upstream data to send in the process carrying out HS-DPCCH, then generate up construction data and carry therein can be unique in sub-district, UE place the identification information of sign UE, then up construction data is sent to network equipment as a kind of upstream data, make the network equipment identify UE, thereby finish the collision detection of the resource that UE is used according to the identification information in the up construction data.Present embodiment makes network equipment to identify according to the identification information that up construction data carries to carry out HS-DPCCH to set up the UE that process does not have upstream data to send, and then can solve the collision problem of the resource that this UE uses, so can triggering a plurality of UE simultaneously, network equipment carries out HS-DPCCH foundation, with once can only trigger a UE in the prior art and carry out the scheme that HS-DPCCH sets up and compare, help reducing UE and carry out the time delay that HS-DPCCH sets up.

Further, to set up the up construction data that the UE that does not have upstream data to send in the process sends to network equipment be not real upstream data because carrying out HS-DPCCH, network equipment only needs to identify UE according to up construction data and gets final product, need not up construction data is carried out too much processing, for example do not need up construction data is reported RNC etc.For this reason, the indication information that present embodiment does not have upstream data to send by the UE that comprises the up construction data of sign transmission in up construction data, to inform that network equipment is after identifying the UE that sends up construction data according to up construction data, do not need again up construction data to be carried out multiprocessing, thereby alleviate the processing burden of network equipment and economize on resources.

Based on above-mentioned, network equipment is no longer only discerned according to detected HS-DPCCH as prior art and is carried out the UE that HS-DPCCH sets up, carry out the UE that HS-DPCCH sets up but discern simultaneously, overcome to a certain extent because of omission or false-alarm lead to a conflict and detected the problem that can't complete successfully according to HS-DPCCH and the up construction data that receives.Wherein, omission is meant that UE has sent HS-DPCCH, but network equipment does not have detected situation.False-alarm is meant that UE does not send HS-DPCCH, and network equipment detects the situation of the HS-DPCCH of this UE.

Preferably, identification information in the up construction data that UE generates can be Radio Network Temporary Identifier (the Radio Network Temporary Identifier of UE, RNTI), E-DCH Radio Network Temporary Identifier (E-DCH RNTI for example, E-RNTI), HS-DSCH Radio Network Temporary Identifier (HS-DSCH RNTI, H-RNTI), Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Cell RNTI, C-RNTI) or universal terrestrial access network temporary mark (Utran RNTI, but be not limited thereto U-RNTI) etc..For example, UE can also use network side can uniquely identify other information of this UE, for example HS-SCCH index, System Frame Number (System Frame Number, SFN), one of them or its combination such as subframe numbers.

Based on above-mentioned, the execution mode that the embodiment of the invention provides several UE to generate up construction data, specific as follows:

First kind: UE directly generates the up construction data that comprises identification information.In this embodiment, up construction data is a process of growing out of nothing concerning UE.

In this embodiment, UE can indicate this UE to set up and do not have upstream data to send in the process carrying out HS-DPCCH by the length of up construction data, promptly the length of up construction data be shown in indication information.Wherein, comparatively preferred, the length of up construction data is 18 bits.Whether network equipment is that 18 bits discern whether the data that receive are up construction data according to the length that receives data.

Further, UE can also be with the content of described indication information as up construction data, and promptly UE directly generates the up construction data that comprises described indication information and described identification information.For example, UE can get up indication information and identification information according to certain form or order encapsulation, form up construction data.By this execution mode, UE can control the form of up construction data and length etc. flexibly, and is comparatively flexible.

In the above-described embodiment, the identification information that is added can be the RNTI of UE, for example E-RNTI, H-RNTI, C-RNTI or U-RNTI etc.

Second kind: UE obtains to measure and reports (Measurement Report) data, adds described indication information and described identification information then in measuring reported data, thereby generates up construction data.Wherein, the identification information that is added can be the RNTI of UE, for example E-RNTI, H-RNTI, C-RNTI or U-RNTI etc.This measurement reported data is meant the data that UE gives the correct time on network equipment is measured, this measurement reported data exists UE.In this embodiment, UE utilizes the data that existed to generate up construction data, and efficient is higher.

The third: UE obtains the measurement reported data, adds described identification information then to generate up construction data in measuring reported data.In this embodiment, UE need make an appointment to use and measure reported data as up construction data with network equipment, that is to say that the sign of measuring reported data itself is described indication information.After network equipment receives and measures reported data, according to the sign of measuring reported data identify receive for measuring reported data, that is identify the up construction data that has received UE.The identification information that is added in this execution mode also can be E-RNTI, H-RNTI, C-RNTI or U-RNTI etc.The efficient of this execution mode is higher.

Further, the following content of the present invention provides a few class UE realization form according to the up construction data of first kind of execution mode generation.

The first kind realize length that form: UE generates the up construction data that comprises described identification information and pass through to be generated as shown in the up construction data of indication information.

Wherein, the length of up construction data is preferably 18 bits.Every length is that the data structure that comprises described identification information of 18 bits all realizes within the protection range of form at such.

In such realized form, why the length of preferred up construction data was that 18 bits are to have considered E-DCH transformat combination indication (E-DCH Transport Format Combination Indicator, operating position E-TFCI) in the prior art.The size that current E-TFCI equals the packet of 0 correspondence is 18 bits, be used for the transmission of SI, network equipment is only handled at low layer after receiving this packet, can not be delivered to high level, consistent with the flow process of handling the up construction data of UE, do not need network equipment to carry out extra judgement, therefore, the length that up construction data is set is 18 bits.

In the prior art, E-TFCI exists three to use table at CELL_FACH.The operating position of E-TFCI in every table is respectively shown in table 1, table 2 and table 3.

Table 1

Table 2

Table 3

In above-mentioned each table, except the value of above-mentioned E-TFCI is the size of the packet of 0 this situation correspondence can be used, some is labeled as N/A or the indicating bit that is not used also can use, this moment, the size of packet no longer was restricted to 18 bits, UE can adopt existing MAC-i/is form to generate up construction data, and carry the identification information that identifies UE, temporarily do not do description herein.

Further, the embodiment of the invention provides several first kind to realize the specific implementation form of up construction data under the form.

Realize form for first kind: up construction data comprises identification information and 2 vacant bits (spare bits) of 16 bits.Wherein, identification information can be E-RNTI, H-RNTI, C-RNTI etc., but is not limited thereto.Fig. 2 A provides the realization form that a kind of identification information is the upstream data of E-RNTI; Fig. 2 B provides the realization form that another kind of identification information is the upstream data of E-RNTI.

The difference of Fig. 2 A and Fig. 2 B is: the position sequencing of the identification information of 16 bits and 2 vacant bits is different.That is to say, realize that form to the position precedence relationship of the identification information of 16 bits and 2 vacant bits without limits for first kind.

Preferably, the value of 2 vacant bits can for: in 00,01,10,11 any one the value, concrete value needs network equipment and UE side to arrange in advance.In this embodiment, the length of up construction data bag is described indication information.Wherein, UE can be 0 by the value that the E-TFCI among the E-DPCCH is set, and to send E-DPCCH to network side be 18 bits with the length of up construction data from E-DPDCH to the network side indication that soon send on.It is that 0 data that identify the E-DPDCH channel are 18 bits and to identify these data be to set up the up construction data that the UE that do not have upstream data to send in the process sends carrying out HS-DPCCH that network side is established according to the E-TFCI among the E-DPCCH, and network equipment successfully receives up construction data according to the length information of E-TFCI indication simultaneously.Wherein, after network equipment identifies up construction data, only can from up construction data, obtain the identification information of sign UE and identify this UE, this up construction data can not submitted to high level etc. and carry out other processing according to the identification information that obtains.

Based on this, because the value of 2 vacant bits is unfixing, clash for fear of upstream data with the UE transmission that has upstream data to send, this execution mode need limit the UE of upstream data transmission before its collision detection timer expiry, can not send the data that length is 18 bits separately, promptly the E-TFCI among the E-DPCCH (E-TFCI in E-DPCCH) can not be set to 0.

Preferably, the value that UE can be provided with 2 vacant bits is a fixed value, for example 11; Described fixed value needs network equipment and UE to make an appointment.It is that E-RNTI, 2 vacant bit values are the realization form of 11 upstream data that Fig. 2 C provides a kind of identification information.In this embodiment, the value of 2 vacant bits is unique.

Based on this, because the value of 2 vacant bits is fixed, clash for fear of upstream data with the UE transmission that has upstream data to send, it is that last two of data of 18 bits can not be 11 that this execution mode need limit length that upstream data sends, the UE that the upstream data transmission is promptly arranged is before its collision detection timer expiry, can send the data that length is 18 bits, but requiring last two of data can not be 11, and promptly the E-TFCI among the E-DPCCH (E-TFCI in E-DPCCH) can be set to 0.For the UE that has data to send, last two (for example HLID) of its 18 Bit data bag can not be 11, and promptly logical channel number is: 0011,1011,0111 logic channel uses for the UE that has upstream data to send.In this embodiment, the fixedly value of length 18 bits of up construction data bag and 2 vacant bits is as described indication information.

Realize form for second kind: up construction data comprises HS-SCCH index (index), SFN and subframe numbers (Sub-frame num) and vacant bit.Realize that at this kind the length of up construction data still is described indication information in the form; And HS-SCCH index, SFN and subframe numbers one of them or its are combined as described identification information.Being network equipment can know E-RNTI, the H-RNTI etc. of UE according to HS-SCCH index, SFN and subframe numbers one of them or its combination in any, thereby reaches the purpose of identification UE.Concrete use in HS-SCCH index, SFN and subframe numbers one of them or its combination in any which to decide on practical situations, for example network equipment and UE have arranged those information, and which information UE just can use do identification information.

Wherein, if be 18 bits as the length of the up construction data of indication information, then HS-SCCH index, SFN, subframe numbers and vacant bit are altogether 18 bits.Comparatively preferred HS-SCCH index takies that 2 bits, SFN take 12 bits, subframe numbers takies 3 bits, vacant bit stealing 1 bit.

Based on above-mentioned, Fig. 2 D provides a kind of second kind of realization form of up construction data.Fig. 2 E provides the another kind of up construction data and realizes form for second kind.Fig. 2 D is with the difference of Fig. 2 E: the sequencing of the position of HS-SCCH index, SFN and subframe numbers is different.That is to say that second kind of realization form do not done qualification to the sequencing of the position of HS-SCCH index, SFN and subframe numbers yet.

Wherein HS-SCCH index representative triggers UE and carries out the numbering of HS-SCCH channel in configuration information that HS-DPCCH sets up, and takies 2 bits, value can for: 00,01,10,11.For example, if the HS-SCCH channel is the 2nd in configuration information, then the HS-SCCH index is 01.

SFN is the System Frame Number of network equipment correspondence when issuing triggering indication information at this UE, and value is 0-4095, accounts for 12 bits.

Subframe numbers is when this SFN, triggers the subframe numbering that UE carries out the HS-SCCH of HS-DPCCH foundation, and this subframe numbering value is 0-4, accounts for 3 bits.

Further, in this embodiment, because the value of HS-SCCH index, SFN and subframe numbers is all unfixing, clash for fear of upstream data with the UE transmission that has upstream data to send, this execution mode need limit the UE of upstream data transmission equally before its collision detection timer expiry, can not send the data that length is 18 bits separately, promptly the E-TFCI among the E-DPCCH (E-TFCI in E-DPCCH) can not be set to 0.

Second class realizes that form: UE directly generates the up construction data that comprises described indication information and described identification information.Realize that at such the length of up construction data is no longer restricted in form.Promptly realize that in second class value of E-TFCI no longer is restricted to 0 in the form.

Further, the specific implementation form that the embodiment of the invention provides several second classes to realize up construction data under the forms, specifically comprise the third the-the 6th kind realize form.

The third implementation structure: up construction data comprises described indication information, SFN and subframe numbers.Wherein, one of them or its of SFN and subframe numbers is combined as described identification information.Being network equipment according to SFN and subframe numbers, one of them or its combination can be known E-RNTI, the H-RNTI etc. of UE, thereby reach the purpose of identification UE.Wherein, the shared bit number of indication information, SFN and subframe numbers is not done qualification.

Consider that network equipment is that the processing of the data of 18 bits is particularly useful for up construction data to length, so realize that at this kind still the length with up construction data is that 18 bits are example, but is not limited thereto in the form.Comparatively preferred, described indication information takies 4 bits, and the value of indication information is fixed value, and SFN and subframe numbers take 14 bits altogether.Wherein, the fixed value of being got of indication information can be 1111, but is not limited thereto.This fixed value needs network equipment and UE to make an appointment.The value that Fig. 2 F provides a kind of indication information be 1111 the third realize form.Comparatively preferred, the indication information of 4 bits is as last 4 of up construction data.

In this embodiment, the network equipment can be a fixed value according to last 4 bits of up construction data, for example 1111, discerning the data that receive is to carry out HS-DPCCH sets up does not have the UE of upstream data transmission transmission in the process up construction data, thereby only can from up construction data, obtain the identification information of sign UE, and identify the UE that sends up construction data so that finish collision detection according to identification information, and this up construction data can not reported high level his processing of Xingqi of going forward side by side.

Preferably, length at up construction data is under the situation of 18 bits, the length that network equipment can also be united up construction data simultaneously is that 18 bits and value are the indication information of 4 bits of fixed value, and identifying the data that receive is to carry out HS-DPCCH sets up does not have the UE of upstream data transmission transmission in the process up construction data.

In this embodiment, network equipment and UE need make an appointment and carry out HS-DPCCH foundation at certain HS-SCCH channel triggering UE.Wherein, on a SFN, can trigger 5 UE at most and carry out HS-DPCCH foundation.

Realize form for the 4th kind: up construction data comprises described indication information, SFN, subframe numbers and HS-SCCH index.Wherein, one of them or its of HS-SCCH index, SFN and subframe numbers is combined as described identification information.Being network equipment can know E-RNTI, the H-RNTI etc. of UE according to HS-SCCH index, SFN and subframe numbers one of them or its combination in any, thereby reaches the purpose of identification UE.Concrete use in HS-SCCH index, SFN and subframe numbers one of them or its combination in any which to decide on practical situations.In this kind implementation structure, the shared bit number of indication information, SFN, subframe numbers and HS-SCCH index is not done qualification.In like manner, consider that network equipment is that the processing of the data of 18 bits is particularly useful for up construction data to length, so realize that at this kind still the length with up construction data is that 18 bits are example, but is not limited thereto in the form.Fig. 2 G provides a kind of the 4th kind of realization form of up construction data.In structure shown in Fig. 2 G, SFN, subframe numbers and HS-SCCH index take 14 bits altogether, and indication information takies 4 bits, and the value of indication information is 1111.Wherein, the value of indication information is a fixed value, but is not limited to 1111, needs network equipment and UE to make an appointment.

Preferably, in the structure, SFN can take 12 bits shown in Fig. 2 G, and subframe numbers can take 1 bit, and the HS-SCCH index can take 1 bit.Wherein, because the HS-SCCH index takies 1 bit, carry out HS-DPCCH foundation so have only two HS-SCCH channels can be used for triggering UE; Subframe numbers takies 1 bit, carries out HS-DPCCH foundation so have only two subframes can be used for triggering UE.That is to say that network equipment can trigger 4 UE at most simultaneously and carries out HS-DPCCH and set up on a SFN.

Length at up construction data is under the situation of 18 bits, the length that network equipment can also be united up construction data simultaneously is that 18 bits and value are the indication information of 4 bits of fixed value, and identifying the data that receive is to carry out HS-DPCCH sets up does not have the UE of upstream data transmission transmission in the process up construction data.

Fig. 2 H provides the another kind of up construction data and realizes form for the 4th kind.In structure shown in Fig. 2 H, SFN, subframe numbers and HS-SCCH index take 16 bits altogether, and indication information takies 2 bits, and the value of indication information is 11.Wherein, the value of indication information is a fixed value, but is not limited to 11, needs network equipment and UE to make an appointment.

In this embodiment, the network equipment can be a fixed value according to last 2 bits of up construction data, for example 11, discerning the data that receive is to carry out HS-DPCCH sets up does not have the UE of upstream data transmission transmission in the process up construction data, thereby only can from up construction data, obtain the identification information of sign UE, and identify the UE that sends up construction data so that finish collision detection according to identification information, and this up construction data can not reported high level his processing of Xingqi of going forward side by side.

In like manner, length at up construction data is under the situation of 18 bits, and the length that network equipment can also be united up construction data simultaneously is that 18 bits and value are that the indication information of 2 bits of fixed value identifies the data that receive for setting up the up construction data that the UE that do not have upstream data to send in the process sends carrying out HS-DPCCH.

Further, in this embodiment, because the value of the indication information of last 2 bits is fixed, clash for fear of upstream data with the UE transmission that has upstream data to send, it is that last two of data of 18 bits can not be 11 that this execution mode need limit length that upstream data sends, the UE that the upstream data transmission is promptly arranged is before its collision detection timer expiry, can send the data that length is 18 bits, but requiring last two of data can not be 11, and promptly the E-TFCI among the E-DPCCH (E-TFCIin E-DPCCH) can be set to 0.For the UE that has data to send, last two of its upstream data can not be 11, and promptly logical channel number is: 0011,1011,0111 logic channel uses for the UE that has upstream data to send.

Further, in each execution mode of the 4th kind of realization form, do not limit the position precedence relationship of HS-SCCH index, SFN and subframe numbers.Comparatively preferred, indication information takies last 4 bits or 2 bits of up construction data.

Realize form for the 5th kind: up construction data comprises the 0th logical channel number LCH-ID0, vacant bit and identification information.Realize that at this kind LCH-ID0 and vacant bit are united as described indication information in the form.

In the prior art, it is 1111 that the value of LCH-ID0 in the upstream data that UE sent that upstream data sends is arranged, and the value of vacant bit is 0000.Compatible mutually in order to realize the data structure that reaches again in maximum and the existing protocol with the differentiation of upstream data, comparatively preferred, the value of LCH-ID0 is 1111, and the value of vacant bit is non-0000 value.Realize that form is shown in Fig. 2 I for the 5th kind.In Fig. 2 I, identification information is E-RNTI, but is not limited thereto; The value of vacant bit is 0001, but is not limited thereto, and can also be non-0000 four bit combinations arbitrarily such as 0011,1111.

In execution mode, LCH-ID0 and vacant bit are united as described indication information; Be that network equipment receives behind the up construction data can LCH-ID0 and the associating value of vacant bit, know that the data that receive are to carry out HS-DPCCH sets up does not have the UE of upstream data transmission transmission in the process up construction data, thereby only can from up construction data, obtain the identification information of sign UE, and identify the UE that sends up construction data so that finish collision detection according to identification information, and this up construction data can not reported high level his processing of Xingqi of going forward side by side.

In form shown in Fig. 2 I, up construction data has only comprised indication information and identification information.In addition, the value of the E-TFCI that is provided with according to UE, this up construction data can also comprise fillings (Padding) information, so that the length of up construction data satisfies the length that E-TFCI indicates.For example, if the E-TFCI value is 1, the length of this up construction data is at least 120 bits or 186 bits, and wherein, remaining bits all is Padding.

Further, the up construction data of present embodiment can also comprise SI information.A kind of structure of up construction data that comprises SI information is shown in Fig. 2 J.UE not only can make network equipment complete successfully collision detection by carry SI information in up construction data, can also make network equipment in time receive the SI of UE, helps more reasonably UE being dispatched.

Realize form for the 6th kind: up construction data comprises LCH-ID0, vacant bit, identification information, the first logical channel number LCH-ID1, length (Length, L), sign (Flag, F), cutting state (Segmentation Status, SS), transmission sequence number (Transmission Sequence Number, TSN), medium access control service data unit (Media Access Control-Service Data Unit, MAC-SDU) and SI, shown in Fig. 2 K.In this embodiment, one of them is described indication information at least for LCH-ID1 and L.For example, UE can be provided with the value of LCH-ID1 be 1111 and/or value that L is set be 0 as indication information.Network equipment according to the value of LCH-ID1 be 1111 and/or the value of L be 0 to identify the data that receive for setting up the up construction data that the UE that do not have upstream data to send in the process sends carrying out HS-DPCCH, thereby only can from up construction data, obtain the identification information of sign UE, and identify the UE that sends up construction data so that finish collision detection according to identification information, and this up construction data can not reported high level his processing of Xingqi of going forward side by side.

Further, network equipment can also be according to the value of LCH-ID1 1111 and/or the value of L be that 0 to identify follow-up MAC-SDU be an empty packet, promptly without any the upstream data content.

Wherein, the value that LCH-ID0 is set is 1111, and the value of vacant bit is 0000, and the value of LCH-ID1 is 1111; Perhaps, the value that LCH-ID0 is set is 1111, and the value of vacant bit is 0000, and the value of L is 0; The value that LCH-ID0 perhaps is set is 1111, and the value of vacant bit is 0000, and the value of LCH-ID1 be 1111 and the value of L be 0 to be comparatively preferred value mode, but be not limited thereto.

In this embodiment, the value of LCH-ID0 is 1111, and the value of vacant bit is 0000, and the structure of the upstream data that sends with the UE that has upstream data to send in the prior art is compatible mutually.Network equipment is known the follow-up identification information that carries sign UE of this up construction data by LCH-ID0 and vacant bit joint instructions.

Further, the value of the E-TFCI that is provided with according to UE, this up construction data also can comprise Padding, so that the length of up construction data satisfies the length of E-TFCI indication.

Further, UE can indicate the length information of up construction data to network equipment by E-DPCCH, so that network equipment receives up construction data according to the indicated length information of UE before sending up construction data to network equipment.Concrete, UE is according to the length of the up construction data that is generated, and is provided with that the value of E-TFCI be the value corresponding with the length of the up construction data that is generated among the E-DPCCH, and the purpose of the length information of up construction data is indicated in realization to network equipment.Preferably, UE can be provided with the value of E-TFCI according to the operating position of E-TFCI in arbitrary table in the table 1-table 3.If the up construction data that UE generates is that length is 18 bits, then the value of E-TFCI can be set is 0 to UE.If the up construction data that UE generates is that length is 120 bits, then the value of E-TFCI can be set is 1 to UE.

Further, if network equipment is being set up the resource that the UE that do not have upstream data to send in the process uses and is being carried out in the collision detection process carrying out HS-DPCCH, determine and to set up unique certain UE that licenses to of resource that the UE that do not have upstream data to send in the process uses carrying out HS-DPCCH that network equipment also can carry the mandate indication information of sign of the UE that is authorized to inform each UE is with unique which UE that licensed to of this resource by transmission.Wherein, the UE that is authorized to is meant that network equipment sets up HS-DPCCH sets up does not have the employed resource of UE that upstream data sends in the process the UE that can unique use carry out that determines among at least one UE that does not have the employed resource of UE that upstream data sends the process from using carrying out HS-DPCCH.Authorize indication information can be carry the UE that is authorized to sign E-AGCH or carry the HS-SCCH of the sign of the UE that is authorized to.Whether wherein, no matter clash on the resource that UE uses, network equipment all can carry out collision detection and send the mandate indication information of the sign of carrying the UE that is authorized to, for example E-AGCH or HS-SCCH.Accordingly, set up the UE that does not have upstream data to send in the process and also can receive the mandate indication information that network equipment sends carrying out HS-DPCCH.The mandate indication information that network equipment sends has comprised the sign of network equipment with the unique UE that licenses to of its employed resource, the sign of the UE that promptly is authorized to.Wherein, if this UE that is authorized to is the UE that does not have upstream data to send, then network equipment can obtain the sign of the UE that is authorized to according to the identification information in this up construction data that UE sent that is authorized to.If the identification information in the up construction data of the UE that is authorized to is exactly the sign of UE, then network equipment can directly obtain the sign of the UE that is authorized to, if the identification information in the up construction data of the UE that is authorized to is not the sign of UE, but HS-SCCH index, subframe numbers, SFN etc., then network equipment can be found the sign of the UE that is authorized to according to these identification informations.If this UE that is authorized to is the UE that has upstream data to send, then network equipment obtains its sign in the line data from it.

After receiving the mandate indication information, the sign of the UE that is authorized to that UE can carry the mandate indication information and the sign of oneself compare, if the sign of the UE that is authorized to is identical with the sign of oneself, illustrate that network equipment licenses to oneself with resource is unique, oneself continue to use this resource; If the sign of the UE that is authorized to is different with the sign of oneself, illustrate that network equipment has licensed to other UE with this resource is unique, then abandons the use to this resource.Use a plurality of UE of same resource all can carry out such operation simultaneously, finally make this resource only be used, solved collision problem by a UE.

Further, UE can start a collision detection timer when sending DPCCH after inserting successfully at random.Then UE needed judge whether the collision detection timer is overtime before the mandate indication information that receives the network equipment transmission; If received the mandate indication information that network equipment sends before the collision detection timer expiry, then this UE further judges according to sign that is authorized to UE in the mandate indication information that receives and the sign of oneself; If do not receive the mandate indication information that network equipment sends yet behind the collision detection timer expiry, then this UE thinks the collision detection failure, directly abandons the use to this resource.UE helps solving and authorizes indication information the problem that waits as long in particular cases such as to lose by starting the collision detection timer.

Preferably, be detected as power when carrying out collision detection in order to improve resource that network equipment uses UE according to up construction data, UE can repeat send up construction data to network equipment before the mandate indication information that receives the network equipment transmission according to predetermined period.Wherein, each up construction data that sends is identical.

Optionally, be detected as power when carrying out collision detection in order to improve resource that network equipment uses UE according to up construction data, a kind of execution mode of step 103 can repeat to send up construction data to network equipment by E-DPDCH for: UE, so that network equipment identifies UE to finish the collision detection of the resource that UE is used according to the identification information in the up construction data.

Further, authorize indication information to inform that UE is with the unique scheme that licenses to which UE of this resource in conjunction with above-mentioned network equipment by sending to UE, the another kind of execution mode of step 103 can for: UE before receiving the mandate indication information that network equipment sends, repetition sends up construction data to network equipment, so that network equipment identifies UE to finish the collision detection of the resource that UE is used according to the identification information in the up construction data.

Further, a kind of preferred implementation of step 103 can for: UE before receiving the mandate indication information that network equipment sends, can repeat send up construction data according to predetermined period to network equipment.

Repeat by E-DPDCH to send on the basis of various execution modes of up construction data to network equipment at above-mentioned UE, the method for present embodiment further can comprise following at least a operation:

If the repeating transmission number of times of up construction data is received mandate indication information or the ACK (correct affirmation) that network equipment sends before reaching maximum HARQ number of retransmissions, UE stops to send this up construction data to network equipment.Wherein, UE is meant to receive on E-AGCH and authorizes indication information; (E-DCH Hybrid Indicator Channel E-HICH) goes up reception ACK and at the E-DCH retransmission indicating chanel.

If the repeating transmission number of times of up construction data reaches maximum HAQR number of retransmissions, this moment, UE did not receive ACK on E-HICH, and then UE stops to send up construction data to network equipment.

Above-mentioned, maximum HAQR number of retransmissions is that network is configurable.

If UE reaches the maximum number that sends to the number of the up construction data that network equipment sends, UE stops to send up construction data to network equipment.

If UE receives the mandate indication information that network equipment sends or confirms that correctly then UE stops to send up construction data to network equipment before the number of the up construction data that sends to network equipment reaches maximum transmission number.

Wherein, above-mentioned maximum transmission number is that network is configurable, and for example network equipment can dispose this maximum by system message and send number, should maximum transmission number be predefined perhaps, and promptly agreement is formulated a fixed value.

In this explanation: above-mentioned maximum to send number be two different amounts with above-mentioned maximum HARQ number of retransmissions.Illustrate, the maximum number that sends is made as 2, maximum HARQ number of retransmissions is made as 4, then send a up construction data, reach maximum HARQ number of retransmissions if repeat to send the number of times of this up construction data, the up construction data that then stops to send this up construction data and resend neotectonics is till the number of the up construction data bag that sends reaches maximum transmission number 2.This shows that the above-mentioned maximum number that sends is meant the maximum number that sends different up construction datas, and maximum HARQ number of retransmissions is the maximum times that repeats to send same up construction data.

If UE detects the sign of this UE on E-AGCH, the E-RNTI of UE for example, then UE stops to send up construction data to described network equipment.

If UE determine UE the medium access control (MediumAccess Control, MAC) or Radio Link control (Radio Link Control RLC) has upstream data to send in the buffer memory, UE stops to send up construction data to network equipment.

If UE reaches maximum time to the time that network equipment sends up construction data continuously, UE stops to send up construction data to network equipment.

If UE is receiving continuously mandate indication information that network equipment sends or is correctly confirming that UE stops to send up construction data to network equipment before the time that network equipment sends up construction data reaches maximum time.

Wherein, above-mentioned maximum time is that network is configurable, for example network then equipment can dispose this maximum time by system message, perhaps this maximum time is predefined, a value that promptly fixedly installs in the agreement.

Optionally, above-mentioned maximum time can be collision detection maximum time.

In this explanation: in the aforesaid operations arbitrarily the combination of two or more operation also be applicable to technical solution of the present invention.Illustrate the operation that operation of above-mentioned maximum number of times of transmission and above-mentioned maximum HARQ number of retransmissions operation combine and produce, and the operation that occurs upstream data in the operation of above-mentioned maximum number of times of transmission and above-mentioned MAC or the RLC buffer memory operation of generation or the like that combines.For a person skilled in the art, the cohesive process of two or more operation can be by the independent beyond all doubt release of carrying out of process of above-mentioned each operation arbitrarily.

The UE of present embodiment is by above-mentioned various operations or it is in conjunction with can solve the problem that sends up construction data to network equipment always, help alleviating interference to other users, and helping alleviating UE repeats to send the burden of up construction data and can economize on resources, especially in the situation that can not receive the Ack that network equipment returns because of some cause specific always, can stop to send up construction data by some operation in the above-mentioned various operations to network equipment, both can alleviate the interference to other users, the transmission burden that can alleviate UE again also helps economizing on resources.

The flow chart of the collision detection method that Fig. 3 another embodiment of the present invention provides.As shown in Figure 3, the method for present embodiment comprises:

Step 301, network equipment send trigger message to UE, set up so that UE carries out HS-DPCCH according to trigger message.

Concrete, network equipment carries out HS-DPCCH foundation by sending trigger message to UE to trigger UE.UE can obtain the signature and the access slot of up access behind the trigger message that receives the network equipment transmission, initiate the process that inserts at random.When network equipment detects the access of UE and but the resource time spent is arranged, network equipment is in AICH channel indication UE uplink resources available.Wherein, the ascending resource of network equipment indication UE comprises that mainly UE carries out up-downgoing and sends required sign indicating number information, and described sign indicating number information comprises HS-DPCCH, E-AGCH etc.Then, UE adopts the ascending resource of network equipment indication to begin to send DPCCH and HS-DPCCH, and the HARQ feedback information is carried on the HS-DPCCH channel.

If UE does not have upstream data to send carrying out setting up of HS-DPCCH in the process, then UE can generate up construction data, and in up construction data, carry can be in sub-district, UE place the identification information of unique identification UE.Then, the UE up construction data that will generate sends network equipment by E-DPDCH.Wherein, the identification information of sign UE can be the sign of UE, and for example E-RNTI, H-RNTI, C-RNTI etc. also can be any other information or its combinations that can make network equipment identify UE.

Step 302, network equipment receive the up construction data that UE sends by E-DPDCH, to be UE set up and generate and send when not having upstream data to send in the process carrying out HS-DPCCH described up construction data, this up construction data comprise unique in sub-district, UE place the identification information of this UE of sign.

Step 303, network equipment identify UE according to the identification information in this up construction data, to finish the collision detection of the resource that this UE is used.

Network equipment is received in and carries out HS-DPCCH sets up does not have the UE of upstream data transmission transmission in the process up construction data.After receiving up construction data, network equipment is resolved up construction data, obtain the identification information in the up construction data, and according to the identification information that obtains identification sends the UE (be present embodiment carrying out HS-DPCCH sets up does not have upstream data to send in the process UE) of this up construction data, thereby finish this present embodiment carrying out HS-DPCCH sets up does not have the employed resource of UE that upstream data sends in the process collision detection.

Wherein, network equipment is set up resource that the UE that do not have upstream data to send in the process uses and is carried out collision detection and be meant that mainly network equipment sets up the resource that the UE that do not have upstream data to send in the process uses and detect the HS-DPCCH that carrying out of present embodiment carrying out HS-DPCCH present embodiment, find whether this resource is also used by other UE simultaneously, and with the unique process that licenses to one of them UE of this resource.Concrete, network equipment can detect the resource that present embodiment UE uses.If on the resource that present embodiment UE uses, also detect the upstream data that the UE of upstream data transmission sends, perhaps also detect other and carrying out HS-DPCCH sets up does not have the UE of upstream data transmission transmission in the process up construction data, network equipment uses unique one of them UE that licenses to of resource that present embodiment UE uses.If do not detect upstream data or the up construction data of other UE on the resource that present embodiment UE uses, the unique UE that licenses to present embodiment of the resource that network equipment directly uses present embodiment UE uses.

Preferably, the network equipment of present embodiment can be the base station, but is not limited thereto.For example, network equipment also can be RNC.

In the present embodiment, network equipment sends trigger message so that UE carries out HS-DPCCH foundation to UE; If UE sets up and does not have upstream data to send in the process carrying out HS-DPCCH, will generate up construction data and carry the identification information of this UE of sign therein, send to network equipment then; Network equipment receives the up construction data that UE sends, and identifies UE according to the identification information in the up construction data that receives, so just can be to the collision detection of the resource of this UE use.Owing to set up the UE that does not have upstream data to send in the process and carry its identification information carrying out HS-DPCCH by up construction data, make network equipment to identify and carrying out HS-DPCCH sets up does not have upstream data to send in the process UE, use same asset simultaneously even carry out a plurality of UE of HS-DPCCH foundation, network equipment also can identify each UE, thereby finish collision detection, therefore, network equipment can trigger a plurality of UE simultaneously and carry out HS-DPCCH foundation, once can only trigger a UE with prior art carries out HS-DPCCH and sets up and to compare, improved UE and carried out the efficient that HS-DPCCH sets up, reduced and carried out the time delay that HS-DPCCH sets up.

Further, the up construction data of UE generation also comprises the indication information that this UE of sign does not have upstream data to send.Can to identify the data that receive according to the indication information in the up construction data be to set up the up construction data that the UE that do not have upstream data to send in the process sends carrying out HS-DPCCH to network equipment like this, thereby only can from up construction data, obtain identification information and identify UE according to identification information, thereby finish collision detection, do not carry out other and handle and this up construction data can not submitted to high level etc., help reducing the processing burden of network equipment and economizing on resources.

Based on above-mentioned, the UE that network equipment is no longer only set up according to detected HS-DPCCH identification carrying out HS-DPCCH as prior art, but simultaneously according to whether detecting HS-DPCCH and whether receive up construction data, improved the accuracy that detects, overcome because of omission or false-alarm lead to a conflict and detected the problem that can't complete successfully.

Wherein, carrying out that HS-DPCCH sets up that the UE that does not have upstream data to send in the process generates the process of up construction data and the structure of the up construction data that generated sees the description of the foregoing description for details, do not repeating them here.Concerning network equipment, can therefrom obtain indication information and identification information according to the specific implementation form of up construction data and about agreement.For example, realize form if up construction data is first kind, then network equipment can directly therefrom obtain identification information, and is that to discern the data that receive are up construction datas to 18 bits according to the length of up construction data.

The flow chart of the collision detection method that Fig. 4 provides for further embodiment of this invention.As shown in Figure 4, the method for present embodiment comprises:

Step 401, network equipment send trigger message to UE, set up so that UE carries out HS-DPCCH according to trigger message.

Step 402, network equipment receive the E-DPCCH that UE sends, and know the length information of up construction data according to this E-DPCCH, so that receive up construction data according to the length information that obtains.

The UE of present embodiment can inform the length information of the up construction data that will send by E-DPCCH to network equipment before sending up construction data to network equipment.Concrete, UE can inform that network equipment is about to the length information of the up construction data that sends by the value of E-TFCI among the E-DPCCH is set.Accordingly, network equipment obtains the length information of up construction data according to the value of E-TFCI among the E-DPCCH.For example, UE is provided with E-TFCI=0, and network equipment can know that the length of up construction data is 18 bits; If UE is provided with E-TFCI=1, network equipment can know that the length of up construction data is at least 120 bits or 186 bits, the E-DCH transmission block size form that concrete size is used with reference to UE.

Wherein, network equipment is known the length of up construction data, helps the up construction data of the correct reception of network equipment.

Further, when the length of up construction data can be represented described indication information, network equipment can be discerned the realization form of up construction data according to the length information that obtains, be convenient to from up construction data, obtain indication information and identification information, further help the resource that UE uses is carried out collision detection.

Step 403, network equipment receive the up construction data that UE sends by E-DPDCH, to be UE set up and generate and send when not having upstream data to send in the process carrying out HS-DPCCH described up construction data, this up construction data comprise unique in sub-district, UE place the identification information of this UE of sign.

Step 404, network equipment determine whether to detect the data of a plurality of UE on the resource that this UE uses according to this up construction data; If determine that the result for being, determines that promptly conflict has taken place the resource that this UE uses, then execution in step 405; Otherwise, execution in step 406.

Above-mentioned steps 401, step 403 and step 404 can not repeat them here referring to the description of step 301 and step 302.

Step 405, network equipment determine that with this UE and common unique which UE that licenses to of resource that uses of other UE execution in step 406 then.

The UE that detects present embodiment when network equipment uses identical resource with other UE, and when promptly detecting conflict, network equipment is determined present embodiment UE and common unique which UE that licenses to of resource that uses of other UE.Wherein, network equipment can be determined common unique which UE that licenses to of resource that uses with a plurality of UE according to the signal strength signal intensity of the sequencing of the data that parse each UE on this resource or each UE that parses etc., this operation belongs to prior art, is not described in detail in this.

Step 406, network equipment send authorizes indication information, and described mandate indication information comprises the sign of the UE that is authorized to unique this resource of use.

If network equipment is determined common unique certain UE that licenses to of resource that uses with a plurality of UE, network equipment carries the mandate indication information (for example E-AGCH or HS-SCCH) of the sign of this UE by transmission, to inform this resource of each UE by unique which UE that licensed to, so far network equipment has been finished the collision detection to this resource.

Wherein, if network equipment determine with the common resource of using of a plurality of UE unique license to present embodiment carrying out HS-DPCCH sets up does not have upstream data to send in the process UE, then network equipment can be known the sign of this UE by the identification information that up construction data carries.If the identification information in the up construction data is exactly the sign of UE, then network equipment can directly parse the sign of UE from up construction data; If the identification information that carries in the up construction data be can this UE of unique identification other information, then network equipment is inferred the sign that or obtain UE according to these information.

If other UE that are authorized to are carrying out HS-DPCCH sets up does not have upstream data to send in the process UE, then its sign also is that network equipment obtains according to the identification information in its up construction data.If other UE that are authorized to are the UE that have upstream data to send, then its sign is that network equipment obtains in the line data from it.

If network equipment on the resource that the UE of present embodiment uses except the up construction data of present embodiment, do not detect the data of other UE, then network equipment can send E-AGCH or HS-SCCH equally directly with the unique UE that licenses to present embodiment of this resource.Carry among this E-AGCH or the HS-SCCH be present embodiment carrying out HS-DPCCH sets up does not have the UE that upstream data sends in the process sign.

In the present embodiment, network equipment is according to identifying UE carrying out the identification information that HS-DPCCH sets up in the up construction data that the UE that do not have upstream data to send in the process sends, network equipment just can trigger a plurality of UE simultaneously and carries out HS-DPCCH and set up like this, even a plurality of UE that carry out HS-DPCCH foundation use identical resource, network equipment also can identify each UE and then complete successfully collision detection, do not need as prior art, once can only to trigger a UE and carry out HS-DPCCH and set up and solve because of carrying out HS-DPCCH sets up does not have UE that upstream data sends and other UE use same asset to cause to conflict in the process problem, thereby reduced the time delay that UE carries out HS-DPCCH foundation.

The flow chart of the collision detection method that Fig. 5 A provides for yet another embodiment of the invention.Shown in Fig. 5 A, the method for present embodiment comprises:

Step 501, network equipment send trigger message to a UE and carry out HS-DPCCH foundation to trigger a UE, and this trigger message is carried on the HS-SCCH channel.

Step 502, a UE receive the trigger message that network equipment sends, and a UE obtains the signature and the access slot of up access then, initiate the process that inserts at random.

Wherein, the signature of the up access that a UE obtains may be the signature that a UE selects in available signature at random, also may be the signature of network equipment appointment, and for example: network equipment can be specified available signature at the HS-SCCH channel.Wherein, the access slot of a UE up access of obtaining is the time slot that UE selects in available time slot at random.

Step 503, when network equipment detects the access of a UE and but the resource time spent is arranged, network equipment is indicated a UE uplink resources available at the AICH channel.

This ascending resource may be acquiescence (default) resource of the symbol correspondence of UE selection, also may be the resource of network equipment by the EAI indication.

Step 504, a UE adopt the resource of network equipment indication to begin to send DPCCH and E-DPCCH.

In step 503, suppose to exist simultaneously the 2nd UE to insert at random.Correspondingly, network equipment is that the 2nd UE has indicated the ascending resource identical with a UE, and like this from the DPCCH transmission, a UE will adopt identical ascending resource to send with the 2nd UE, and will clash this moment on this ascending resource.

The data of the UE that step 505, network equipment basis receive on E-DPDCH, the ascending resource that a UE is used carries out collision detection, and sends E-AGCH, carries the sign of the UE that is authorized among this E-AGCH.

Wherein, conflict on the identical ascending resource had both comprised being triggered by network equipment carries out that a plurality of UE that HS-DPCCH sets up use this ascending resource simultaneously and the conflict that causes, also comprise triggering and carry out that the UE that HS-DPCCH sets up and the UE that transmitting uplink data is arranged are used this ascending resource simultaneously and the conflict that causes, comprise also that a plurality of UE that transmitting uplink data arranged use this ascending resource simultaneously and the conflict that causes by network equipment.If cause that the object of conflict is the UE that transmitting uplink data is arranged, the data of the UE that then receives on E-DPDCH are upstream datas that the UE transmission of transmitting uplink data is arranged.If causing the object of conflict is to carry out HS-DPCCH foundation and carrying out HS-DPCCH sets up does not have upstream data to send in the process UE, then the data at the UE that receives on the E-DPDCH are to carry out the up construction data that HS-DPCCH sets up the UE transmission that does not have transmitting uplink data in the process.

Wherein, the form of upstream data is shown in Fig. 5 B.LCH-ID0=1111 wherein, the vacant bit=follow-up E-RNTI that carries UE of 0000 representative is so that network equipment is finished the process of collision detection.

Process for the collision detection of the UE that transmitting uplink data is arranged is: have the UE of transmitting uplink data to start the collision detection timer simultaneously when beginning E-DCH transmission, before collision detection was finished, UE need carry the sign E-RNTI of UE at the E-DCH data packet head.Network equipment detects the upstream data bag of the E-RNTI that comprises UE on the ascending resource of indication after, determine whether with this resource unique license to this UE, if network equipment licenses to this UE with this ascending resource, then comprise the E-RNTI of UE at the E-AGCH channel.UE receives after this E-AGCH, and the transmission packet header of follow-up data bag no longer comprises E-RNTI.

Comprise for the collision detection process that triggers the UE that carries out HS-DPCCH foundation by network equipment: if just in time also have the upstream data bag to need transmission at this UE of collision detection stage, then UE carried the sign E-RNTI of UE at the E-DCH data packet head before collision detection is finished, thereby made network equipment finish collision detection to UE.This collision detection process is identical with the collision detection process of the UE with transmitting uplink data, no longer describes in detail.If do not have upstream data to need transmission (being the described HS-DPCCH of carrying out of various embodiments of the present invention sets up does not have upstream data to send in the process UE) at collision detection stage UE, in order to finish collision detection, UE need construct up data packets for transmission (being up construction data) and carry therein can unique identification information that identifies UE in the sub-district.Network equipment detects the up construction data of the identification information that comprises unique identification UE on the ascending resource of indication after, determine whether with this resource unique license to this UE, if network equipment licenses to this UE with this ascending resource, then comprise the E-RNTI of UE at the E-AGCH channel.UE receives after this E-AGCH, and the transmission packet header of follow-up data bag no longer comprises its identification information.Wherein, the E-RNTI of UE is obtained according to the identification information in the up construction data by network equipment.

In the present embodiment, suppose that a UE is carrying out HS-DPCCH sets up does not have transmitting uplink data in the process UE, and the 2nd UE is the UE that transmitting uplink data is arranged.Based on this, network equipment detects on the ascending resource that a UE uses, and detects the up construction data that a UE sends simultaneously, also detects the upstream data that the 2nd UE sends.Then, network equipment for example detects the sequencing of the data of UE according to certain strategy, with unique one of them UE that licenses to of this ascending resource.In the present embodiment, suppose that network equipment detects the up construction data of a UE on this ascending resource earlier, so network equipment determines that promptly a UE is the UE that is authorized to the unique UE that licenses to of this ascending resource.Then, the identification information in the up construction data that network equipment sends according to a UE obtains the sign of a UE, and E-RNTI for example is carried at the ERNTI of a UE among the E-AGCH then and sends.

Step 506, a UE judge the collision detection result according to the E-AGCH that receives, and carry out corresponding operating according to testing result.

Concrete, for the UE that carries out collision detection, after receiving the E-AGCH that network equipment returns, can judge whether oneself is by unique UE that licenses this resource according to the sign of the UE that is authorized to that carries among the E-AGCH and the sign of oneself.

In the present embodiment, after the one UE receives the E-AGCH of network equipment transmission, E-AGCH is resolved, obtain the sign of the UE that wherein is authorized to, the sign of the UE that is authorized to that will obtain then compares with the sign of oneself, the sign of finding oneself is identical with the sign of the UE that is authorized to that obtains, then determines oneself to be by unique UE that licenses this ascending resource, and continues to use this ascending resource.

For the 2nd UE, also can receive the E-AGCH that network equipment sends.Simultaneously, the 2nd UE also can resolve E-AGCH, obtain the sign of the UE that wherein is authorized to, then sign of oneself and the sign of the UE that is authorized to that obtains are compared, the sign of finding oneself is different with the sign of the UE that is authorized to that obtains, determine oneself not by unique UE that licenses this ascending resource, so abandon use to this ascending resource.

Further, if UE has started the collision detection timer when sending DPCCH, UE need judge whether to receive the E-AGCH that network equipment sends before the collision detection timer expiry.If collision detection timer expiry, UE are not received the feedback of any network equipment, for example comprise the E-AGCH channel of the E-RNTI of UE, know the collision detection failure, no longer continue to use this resource; If in the collision detection timer valid period, UE receives the feedback of network equipment about resource authorization, the E-AGCH channel that for example comprises the E-RNTI of UE is known collision detection success, and sign and the sign of itself of the UE that carries according to E-AGCH determine whether to continue to use this resource.

For a UE and the 2nd UE, when sending DPCCH, also to start the collision detection timer.If collision detection timer expiry, a UE or the 2nd UE are not received the E-AGCH that any network equipment sends, then think and the collision detection failure no longer continue to use this resource; If in the collision detection timer valid period, the one UE or the 2nd UE receive the E-AGCH that network equipment sends, then think collision detection success, sign and the own sign of the UE that is authorized to that carries according to E-AGCH are done further judgement to determine whether to continue this ascending resource of use.

In this explanation, when the UE that carries out HS-DPCCH foundation has started the collision detection timer when sending DPCCH, then set up the UE that the UE that does not have upstream data to send in the process is meant does not have upstream data to send in the collision detection timer valid period carrying out HS-DPCCH described in the various embodiments of the present invention, in other words conj.or perhaps the UE that before collision detection finishes, does not have upstream data to send.

Preferably, the UE that carries out HS-DPCCH foundation in the collision detection process can repeat to send up construction data till the collision detection process finishes always, to guarantee the accuracy of collision detection.

In the present embodiment, UE and network equipment cooperatively interact, carry out HS-DPCCH set up the UE that does not have transmitting uplink data in the process carrying out HS-DPCCH set up in the process by generate up construction data and carry therein can unique identification UE identification information, network equipment identifies UE according to the identification information in the up construction data, thereby finishes collision detection.So no matter the UE of transmitting uplink data is arranged or carrying out HS-DPCCH sets up does not have transmitting uplink data in the process UE, network equipment all can identify and can finish collision detection, based on this, network equipment just can trigger a plurality of UE simultaneously and carry out HS-DPCCH foundation, needn't as prior art, once can only trigger a UE and carry out HS-DPCCH foundation, improved UE and carried out the efficient that HS-DPCCH sets up, reduced UE and carried out the time delay that HS-DPCCH sets up.
