See also Fig. 1, the schematic flow sheet of a kind of HS-DPCCH uplink feedback method that Fig. 1 provides for the embodiment of the invention.

101, UE receives the indication information that NodeB sends by down physical channel, and the Radio Network Temporary Identifier that this indication information comprises UE at least (for example: H-RNTI) and the resource information of random access; Wherein, UE is under CELL-FACH state or CELL-PCH state or the URA-PCH state.

As an optional execution mode, the UE that is under CELL-FACH state or CELL-PCH state or the URA-PCH state does not have upstream data to send.Certainly, when being in UE under CELL-FACH state or CELL-PCH state or the URA-PCH state and having upstream data to send, do not affect the realization of the embodiment of the invention yet.

For instance, in the embodiment of the invention, down physical channel can include but not limited to obtain indicating channel (Acquisition Indicator Channel, AICH), High-Speed Shared Control Channel (High Speed Shared Control Channel, HS-SCCH), E-DCH absolute grant channel (E-DCH Absolute Grant Channel, E-AGCH), E-DCH relative authorization channel (E-RGCH), fractional dedicated physical channel (Fractional DPCH, F-DPCH).The embodiment of the invention is follow-up not to be repeated.

102, UE adopts above-mentioned resource information to initiate random access to NodeB, and detects NodeB and be used to indicate whether successful feedback information of the random access of UE by what down physical channel sent.

If 103 above-mentioned feedback information indication UE access successfully at random, then UE is sent to NodeB by DPCCH with power control information, and according to the timing relationship of HS-DPCCH and HS-PDSCH, report the feedback information of the downlink data that HS-DSCH carries and/or the CQI of the down channel that UE measures to be sent to NodeB in the time that meets timing relationship by HS-DPCCH.

In the embodiment of the invention, the feedback information of the downlink data that HS-DSCH carries is confirmation ACK or unacknowledged information NACK.When UE can correctly receive the downlink data that HS-DSCH carries, then report " ACK "; When UE can not correctly receive the downlink data that HS-DSCH carries, then report " NACK ".

In the embodiment of the invention, UE reports NodeB by DPCCH with power control information, so that NodeB can starting power control.

In the practical application, UE can be sent to NodeB after a period of time with power control information by DPCCH, again according to the timing relationship of HS-DPCCH and HS-PDSCH, report the feedback information of the downlink data that HS-DSCH carries and/or the CQI of the down channel that UE measures to be sent to NodeB in the time that meets timing relationship by HS-DPCCH.Wherein, this section period can also can the Adoption Network side and the UE mode of making an appointment by network side configuration.

In the embodiment of the invention, needed resource information when above-mentioned resource information refers to the random access of UE initiation, this resource information can be one or more in signature index (signature index), ascending resource index (resource index), Physical Random Access Channel (PhysicalRandom Access Channel, PRACH) channel information, the access slot information.

For instance, above-mentioned resource information can comprise the signature index that is used for carrying out independent HS-DPCCH feedback of reservation; Perhaps, above-mentioned resource information can comprise be used to the signature index and the resource index that carry out independent HS-DPCCH feedback, correspondingly UE adopts this signature to initiate random access and obtains after the affirmation feedback of NodeB, can adopt resource corresponding to this resource index to carry out the HS-DPCCH feedback and report.Correspondingly, the resource that the feedback information of the downlink data that the resource that UE transmission power control information adopts and transmission HS-DSCH carry and/or the CQI of the down channel that UE measures adopt can be the indicated resource of down physical channel, or reservation resource corresponding to the upper signature of down physical channel (such as High-Speed Shared Control Channel (High Speed Shared Control Channel, HS-SCCH)).This reservation resource can be in SIB the mode that retrains in advance of definition or employing and network side.

Again for instance, above-mentioned resource information can comprise that initiating random access for UE obtains PRACH channel information and the signature index that HS-DPCCH feeds back; Perhaps, above-mentioned resource information comprises that initiating random access for UE obtains access slot information and the signature index that HS-DPCCH feeds back.

The HS-DPCCH uplink feedback method that provides in order to understand better the embodiment of the invention below illustrates by specific embodiment.In following specific embodiment, UE all is under the CELL-FACH state, and does not have upstream data to send; When UE is under CELL-PCH state or the URA-PCH state, and do not have upstream data to send or embodiment process and following embodiment process when having upstream data to send similar, the embodiment of the invention is not repeated.

A kind of embodiment (reserving signature index scheme)

In the present embodiment, the Signature sequence repeats 16 times and sends at PRACH as leading (preamble), and the random access style that NodeB can distinguish according to the signature that UE selects UE is in order to carry out independently (stand alone) HS-DPCCH feedback or in order to send upstream data.For so that NodeB can distinguish the random access style of UE is in order to carry out independently the HS-DPCCH feedback or to send upstream data, can be with the signature Further Division, reserve several signature and be used to indicate the scene of carrying out independent HS-DPCCH feedback (be that UE adopts the signature that reserves to initiate random access, the base station is according to knowing that to the parsing of preamble among the PRACH this UE applies for resource in order to send independently the HS-DPCCH feedback).Wherein, the signature index of reservation can be broadcast to UE by system broadcast message, also can adopt the mode of default configuration.

The scheme of the present embodiment one is as follows:

The UE that is under the CELL_FACH state need to carry out the HS-DPCCH uplink feedback, and when not having upstream data to send:

1, UE receives the indication information that NodeB sends by down physical channel, and this indication information comprises the H-RNTI of UE at least, signature index; This indication information can also comprise resource index or PRACH index further; This indication information also can only comprise the H-RNTI of UE, and further this indication information can also comprise PRACH index.

In the present embodiment one, the signature index that this indication information comprises reserves, and is used to indicate the scene of carrying out independent HS-DPCCH feedback.

Above-mentioned several indication information can adopt following several form to represent lower following (form one):

H-RNTI

signature index

Or

H-RNTI

PRACH index

signature index

Or

H-RNTI

resource index

signature index

Or

H-RNTI

PRACH index

signature index

resource index

Above-mentioned several form only represents several forms of indication information, and the every sequencing in the form is not construed as limiting.In the embodiment of the invention, if can be the by other means unique sign UE of network side, the mode of time-sharing multiplex for example, then H-RNTI can not be included in the indication information.

If the type of the allocated resource that network side needs can also further comprise the indication information of resource type in above table.

2, after UE receives the indication information that down physical channel sends, adopt the signature of this indication information to initiate the process of random access, and detect NodeB and be used to indicate whether successful feedback information of the random access of UE by what down physical channel sent.

In random access procedure, because the signature that network side specifies UE to adopt, so UE can no longer be confined to the mode that current access slot (access slot) is selected, the random access of access slot initiation that can close on arbitrarily.

3, after NodeB detects the signature of UE initiating random access procedure, at down physical channel (such as AICH/E-RGCH/E-AGCH, subsequent embodiment is take the AICH channel as the example description scheme) the middle feedback information of replying, whether successfully be used to indicate the random access of UE.

4, UE detect random access successfully after, by DPCCH power control information is sent to NodeB, and according to the timing relationship of HS-DPCCH and HS-PDSCH, the feedback information (being ACK or NACK) of the downlink data that HS-DSCH is carried by HS-DPCCH in the time that meets timing relationship and/or the CQI feedback of the down channel that UE measures are sent to NodeB.

Wherein, the feedback information of the downlink data that the resource that UE transmission power control information adopts and transmission HS-DSCH carry and/or the resource that CQI adopts are default resource corresponding to this signature, or EAI is to the indicated resource of UE, or the indicated resource of down physical channel.

In the present embodiment one, the reservation signature that UE adopts is the network side appointment, does not therefore need to carry out the collision detection process.Wherein, NodeB also can indicate signature and ascending resource index corresponding to this signature of reserving simultaneously in down physical channel.

In the present embodiment one, except distinguishing the scene difference of the random access of UE by the signature that reserves, also can distinguish by different PRACH channel informations or access slot (access slot) information.This moment network side can be when independent HS-DPCCH uplink feedback be initiated in down physical channel indication the employed PRACH channel information of UE or access slot information, the employed PRACH channel information of UE or access slot information in the time of also can in system broadcast message, broadcast the independent HS-DPCCH uplink feedback of initiation.

In the embodiment of the invention, consider that resource type is different, can allow UE to carry out the selection of resource type.Particularly, can according to the difference of current TTI length, resource be divided into 2ms (millisecond) TTI (Transmission Time interval) resource and 10ms TTI resource.UE is after setting up the HS-DPCCH feedback, and when having upstream data to transmit, UE can directly utilize this HS-DPCCH feedback resources to carry out the transmission of upstream data.In current 3GPP standard, UE can select different resource types when initiating transmitting uplink data, improves the efficient of transfer of data.But the scheme of discussing among the current 3GPP all is not suitable for UE carries out the selection of resource type when setting up the HS-DPCCH feedback, and therefore in order to allow UE to carry out the selection of resource type when setting up the HS-DPCCH feedback, the present embodiment also provides following scheme:

1, UE receives the indication information that NodeB sends by down physical channel, and this indication information comprises the H-RNTI of UE at least, signature index; This indication information can also comprise resource index or PRACH channel scrambler further.

Wherein, the form of indication information can (form two) as follows:

H-RNTI

signature index 1

signature index2

Or

Or

Or

H-RNTI

resource index1

resource index 2

Or

Wherein, signature index 1 and signature index 2 represent respectively signature corresponding to different resource type.For example: UE selects signature 1 to access at random and then represents the resource that UE has selected 10ms TTI, and UE selects signature 2 to access at random and then represents the resource that UE has selected 2ms TTI.

When the current network side had many PRACH channels to exist, network side also needed to specify UE to initiate the PRACH channel of random access, i.e. above-mentioned PRACH index 1 and PRACH index 2.PRACHindex can be the numbering of PRACH channel in system broadcast message, also can be the numbering of PRACH channel scrambler.

Further, network side can also allocated resource be numbered when specifying signature.If UE selects signature 1, then competing the resource that obtains is the resource of resource index 1 correspondence, if UE selects signature 2, then competing the resource that obtains is the resource of resource index 2 correspondences.

Further, network side can also be specified PRACH index simultaneously, signature index and resource index.

Above-mentionedly distinguish different resource types with current 2ms TTI with 10ms TTI, the present embodiment is not limited to this.For example: when introducing other TTI types and allowing UE to select, can further in above-mentioned indication information, increase the indication of distinguishing this resource type.

Tactful different for the ability of UE and networking side, network side can adopt the form of embodiment one correspondence to carry out the triggering of HS-DPCCH feedback for the UE that does not support/do not need TTI to select.Perhaps, when network side does not wish that UE carries out the TTI type selecting, adopt the form of embodiment one correspondence to carry out the triggering of HS-DPCCH feedback.For the form that guarantees the differentiation down physical channel that UE can be correct (for example: the HS-SCCH form), in down physical channel, also need to increase indicating bit, the type of indicating downlink physical channel: the form of the form of form one correspondence or form two correspondences.

In order to guarantee the consistency of descending indication information form, network side also can only adopt form corresponding to the present embodiment two to indicate, the corresponding UE that does not support that TTI selects, the indicating bit of signature index 1, PRACH index 1, resource index 1 and signature index 2, PRACH index 2, resource index 2 correspondences is set to identical value and gets final product in the above-mentioned indication information.Do not need to increase the form indicating bit this moment.

When network side does not allow UE to carry out the TTI type selecting, UE sends the mode that the employed TTI type of upstream data can adopt default configuration, this default configuration can be the TTI type that need to use of UE that network side is broadcasted in system broadcast message or network side and UE make an appointment do not carrying out TTI employed TTI type or acquiescence TTI type corresponding to this resource when selecting.For example: this moment, UE can only adopt 10ms TTI type to carry out that data send or network side can broadcast the type that UE adopts when not carrying out the TTI type selecting in system broadcast message or adopt the mode that retrains in advance, when not carrying out the TTI type selecting, UE and network side are arranged a kind of TTI type.

When a cover resource can only corresponding 1 TTI type, the TTI type of the resource of the corresponding acquiescence of signature is determined, when network side did not allow UE to carry out the TTI type selecting, UE used the TTI type of the corresponding resource of this signature to carry out the transmission of upstream data.

In the invention process, when network side (for example base station) specifies UE to carry out up access, network side (for example base station) can send at down physical channel the index of the signature sequence of a use to UE, after UE carries out the TTI selection, in order to inform that TTI that network side (for example base station) UE selects is 10ms TTI or 2ms is TTI, can have two ways:

First method is can adopt to send the different TTI that this signature sequence is selected in order to representative on the different PRACH channels, the TTI that this method requirement is different and the corresponding relation of scrambler can be pre-defined, also can by broadcast TTI and PRACH corresponding relation be issued UE by network, the TTI that network side uses by detecting scrambler identification UE expectation.

Second method is that UE adopts two signature sequences to represent respectively the TTI of 2ms or 10ms, but because network side (for example base station) has only specified a signature sequence to UE, therefore UE need to determine in addition available signature sequence according to the unpaired message of signature sequence in the broadcast, UE determines after these two available signature sequences determine to use which signature sequence according to the TTI that selects.Therefore but network need to be in system broadcast message send to UE with unpaired message and the corresponding TTI information thereof of signature sequence in this method, and the TTI information of using by detecting signature identification UE expectation that UE uses.

For example: independent (standalone) HS-DPCCH of broadcasting sets up corresponding signature in system broadcast message, and the corresponding relation between each signature, for example: Signature 1, signature 2, signature 3, signature 4, and signature 5 is the operable signature of UE when setting up standalone HS-DPCCH.The resource type of signature 1, signature 3 and signature 5 corresponding 10ms TTI wherein, the resource type of signature 2 and signature 4 corresponding 2ms TTI.Wherein signature1 and signature 2, there are one-to-one relationship in signature 3 and signature 4, that is:

When network side (for example base station) allows UE to carry out the selection of resource type, issue signature 1 (or signature 2) at the HS-SCCH channel, use signature 1 (or signature 2) to initiate at random access if UE has selected resource type (such as 2msTTI) corresponding to signature 1 (or signature2); If UE selects resource type (such as 10msTTI) corresponding to non-signature 1 (or signature 2), then UE uses the signature 2 (or signature 1) of pairing to initiate at random access.This moment, the form of HS-SCCH was:

H-RNTI

signature index1

In order to guarantee that network side (for example base station) to the control of UE, can also increase indicating bit in HS-SCCH, whether indication network side (for example base station) allows UE to carry out the selection of resource type.

Same, network side (for example base station) also can be broadcasted resource type corresponding to different PRACH channels in system broadcast message, for example:

When UE adopts PRACH 1 to initiate random access, think that then UE (for example: 10ms TTI) selects resource type one;

When UE adopts PRACH 2 to initiate random access, think that then UE (for example: 2ms TTI) selects resource type two.

When network side (for example base station) triggering UE set up standalone HS-DPCCH, the form of HS-SCCH was as follows:

H-RNTI

signature index

UE selects resource type according to above-mentioned trigger message, when UE selects 10ms TTI, then sends this signature at PRACH 1, when UE selects 2ms TTI, then sends this signature at PRACH 2, informs the selection result of network side UE with this.

In such scheme, network side (for example base station) can be broadcasted this corresponding relation in system broadcast message, further also can adopt the mode of UE and network side (for example base station) above-mentioned rule/corresponding relation of making an appointment.

2, after UE receives the indication information of down physical channel transmission, select resource type, adopt PRACH channel corresponding to this resource type and/or signature to initiate the process of random access, and detect Node B and be used to indicate whether successful feedback information of the random access of UE by what down physical channel sent.

In random access procedure, because PRACH channel and/or signature that network side specifies UE to adopt, therefore UE can no longer be confined to the mode that current access slot (access slot) is selected, and can initiate random access at the access slot that closes on arbitrarily.

Node B can change the resource type that UE selects in this step.

When UE selected a certain resource type, Node B replied NACK at AICH, and the resource type that then represents the UE selection is unavailable, and UE directly uses another resource type; Perhaps

When UE selected a certain resource type, Node B allowed the resource type of employing at AICH indication UE network side; Perhaps

When UE selected a certain resource type, Node B specified other resource types at EAI, and UE adopts the resource of Node B appointment to carry out the foundation of HS-DPCCH feedback.

Concrete resource corresponding to above-mentioned resource type by network side before random access or the random access procedure indicating.

Above-mentioned access successfully refers to the employed resource type when sending upstream data of knowing that UE can be clear and definite.

In the above-described embodiments, whether Node B need to support TTI to select to judge the form of the down physical channel of transmission according to UE.Wherein the ability information of UE is indicated by the FP (Frame Protocol) that RNC sends to Node B.When UE supported the TTI type selecting, RNC supported the ability indication of TTI type selecting at FP indicating UE, the form of the down physical channel when determining that according to this indication information triggering the HS-DPCCH feedback sets up for Node B is follow-up.

Another kind of embodiment (indicating any signature and resource index)

In the present embodiment two, do not need to reserve signature for the scene of initiating independent HS-DPCCH uplink feedback, concrete solution is as follows:

The UE that is under the CELL_FACH state need to send the HS-DPCCH uplink feedback, and when not having upstream data to send:

1, UE receives the indication information that NodeB sends by down physical channel (such as HS-SCCH), and this indication information comprises the H-RNTI of UE at least, signature index and resource index;

For instance, in the present embodiment two, signature can be any one among 16 signature, and not needing network side is that independent HS-DPCCH feedback is reserved.

2, after UE receives the indication information that down physical channel sends, adopt the signature of this indication information to initiate the process of random access, and detect NodeB and be used to indicate whether successful feedback information of the random access of UE by what AICH sent;
