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

101, UE receives the indication information that NodeB is sent by down physical channel, and this indication information at least comprises the Radio Network Temporary Identifier (such as: H-RNTI) of UE and the resource information of Stochastic accessing; Wherein, under UE is in CELL-FACH state or CELL-PCH state or URA-PCH state.

As an optional execution mode, the UE be under CELL-FACH state or CELL-PCH state or URA-PCH state does not have upstream data to send.Certainly, when the UE be under CELL-FACH state or CELL-PCH state or URA-PCH state has upstream data to send, the realization of the embodiment of the present invention is not affected yet.

For example, in the embodiment of the present 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 Grant Channels (E-RGCH), fractional dedicated physical channel (Fractional DPCH, F-DPCH).The embodiment of the present invention is follow-up not to be repeated.

102, UE adopts above-mentioned resource information to initiate Stochastic accessing to NodeB, and detect that NodeB sent by down physical channel be used to indicate UE Stochastic accessing whether successfully feedback information.

If 103 above-mentioned feedback information instruction UE Stochastic accessing successes, then power control information is sent to NodeB by DPCCH by UE, and according to the timing relationship of HS-DPCCH and HS-PDSCH, the CQI of the down channel that the feedback information of the downlink data reporting HS-DSCH to carry by HS-DPCCH in the time meeting timing relationship and/or UE measure is sent to NodeB.

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

In the embodiment of the present invention, power control information is reported NodeB by DPCCH by UE, and NodeB can starting power be controlled.

In practical application, after power control information can be sent to NodeB a period of time by DPCCH by UE, again according to the timing relationship of HS-DPCCH and HS-PDSCH, the CQI of the down channel that the feedback information of the downlink data reporting HS-DSCH to carry by HS-DPCCH in the time meeting timing relationship and/or UE measure is sent to NodeB.Wherein, this period of time can configure the mode that network side and UE also can be adopted to make an appointment by network side.

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

For example, above-mentioned resource information can comprise the reserved signature index for carrying out independent HS-DPCCH feedback; Or, above-mentioned resource information can comprise signature index for carrying out independent HS-DPCCH feedback and resource index, correspondingly UE adopt this signature initiate Stochastic accessing and obtain NodeB confirmation feedback after, can adopt resource corresponding to this resource index perform HS-DPCCH feedback report.Correspondingly, the resource that UE transmission power control information adopts and the resource that the CQI sending the feedback information of the downlink data that HS-DSCH carries and/or the down channel of UE measurement adopts can be the resources indicated by down physical channel, or the reserved resource that the upper signature of down physical channel (as High-Speed Shared Control Channel (High Speed Shared Control Channel, HS-SCCH)) is corresponding.The mode that this reserved resource can define or adopt in SIB and network side retrains in advance.

Again for example, above-mentioned resource information can comprise the PRACH channel information and the signature index that initiate Stochastic accessing acquisition HS-DPCCH feedback for UE; Or above-mentioned resource information comprises initiates for UE access slot information and the signature index that Stochastic accessing obtains HS-DPCCH feedback.

In order to understand the HS-DPCCH uplink feedback method that the embodiment of the present invention provides better, illustrate below by way of specific embodiment.In following specific embodiment, under UE is all in CELL-FACH state, and upstream data is not had to send; Under UE is in CELL-PCH state or URA-PCH state, and do not have upstream data send or have upstream data to send time embodiment process and following embodiment process similar, the embodiment of the present invention is not repeated.

A kind of embodiment (reserved signature index scheme)

In the present embodiment, Signature sequence repeats 16 times and sends at PRACH as leading (preamble), and the Stochastic accessing type that the signature that NodeB can select according to UE can distinguish UE to feed back or in order to send upstream data to carry out independently (stand alone) HS-DPCCH.In order to the Stochastic accessing type making NodeB can distinguish UE is to carry out independently HS-DPCCH feedback or transmission upstream data, can by signature Further Division, reserved several signature is used to indicate the scene (namely UE adopts reserved signature to initiate Stochastic accessing, and base station is according to knowing that to the parsing of preamble in PRACH this UE applies for resource to send independently HS-DPCCH and feeding back) of carrying out independent HS-DPCCH feedback.Wherein, reserved signature index 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 be under CELL_FACH state needs to carry out HS-DPCCH uplink feedback, and when not having upstream data to send:

1, UE receives the indication information that NodeB is sent by down physical channel, and this indication information at least comprises the H-RNTI of UE, signature index; This indication information can also comprise resource index or PRACH index further; This indication information also only can 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 is reserved, 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 form is not construed as limiting.In the embodiment of the present invention, if the mark UE that network side can be unique by other means, the mode of such as time-sharing multiplex, then H-RNTI can not be included in indication information.

If the type of the allocated resource that network side needs, can also comprise the indication information of resource type further 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 Stochastic accessing, and detect that NodeB sent by down physical channel be used to indicate UE Stochastic accessing whether successfully feedback information.

In the random access procedure, due to the signature that network side specifies UE to adopt, therefore UE no longer can be confined to the mode that current access slot (access slot) is selected, and can initiate Stochastic accessing at the access slot closed on arbitrarily.

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

4, UE is after Stochastic accessing success being detected, by DPCCH, power control information is sent to NodeB, and according to the timing relationship of HS-DPCCH and HS-PDSCH, the CQI feedback of the down channel that the feedback information (i.e. ACK or NACK) of the downlink data carried by HS-DSCH by HS-DPCCH in the time meeting timing relationship and/or UE are measured is sent to NodeB.

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

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

In the present embodiment one, except being distinguished except the scene difference of UE Stochastic accessing by reserved signature, also can be distinguished by different PRACH channel informations or access slot (access slot) information.Now network side can when independent HS-DPCCH uplink feedback is initiated in down physical channel instruction the PRACH channel information that uses of UE or access slot information, the PRACH channel information that when also can broadcast the independent HS-DPCCH uplink feedback of initiation in system broadcast message, UE uses or access slot information.

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

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

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

H-RNTI

signature index 1

signature index2

Or

H-RNTI

resource index1

resource index 2

Or

Wherein, signature index 1 and signature index 2 represents signature corresponding to different resource type respectively.Such as: UE selects signature 1 to carry out Stochastic accessing and then represents the resource that UE have selected 10ms TTI, UE selects signature 2 to carry out Stochastic accessing and then represents the resource that UE have selected 2ms TTI.

When having many PRACH channels to exist in current network side, network side also needs to specify UE to initiate the PRACH channel of Stochastic accessing, namely 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 scrambling code.

Further, network side allocated resource can also be numbered while appointment signature.If UE selects signature 1, then compete the resource that the resource obtained is resource index 1 correspondence, if UE selects signature 2, then compete the resource that the resource obtained is resource index 2 correspondence.

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

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

Ability for UE is different with the strategy of side, networking, network side for not supporting/UE that do not need TTI to select can adopt the form of embodiment one correspondence to carry out the triggering of HS-DPCCH feedback.Or, when network side does not wish that UE carries out TTI type selecting, adopt the form of embodiment one correspondence to carry out the triggering of HS-DPCCH feedback.In order to ensure the form (such as: HS-SCCH form) of differentiation down physical channel that UE can be correct, also need to increase indicating bit, the type of indicating downlink physical channel: the form of form one correspondence or the form of form two correspondence in down physical channel.

In order to ensure the consistency of descending indication information form, the form two that network side also can only adopt the present embodiment corresponding indicates, correspondence does not support the UE that TTI selects, and in above-mentioned indication information, the indicating bit of signature index 1, PRACH index 1, resource index 1 and signature index 2, PRACH index 2, resource index 2 correspondence is set to identical value.Now do not need to increase form indicating bit.

When network side does not allow UE to carry out TTI type selecting, UE sends the mode that the TTI type that uses of upstream data can adopt default configuration, and this default configuration can be acquiescence TTI type corresponding to UE that network side is broadcasted in the system broadcast message TTI type that needs to use or network side and the UE TTI type used when not carrying out TTI and selecting of making an appointment or this resource.Such as: now UE can only adopt 10ms TTI type to carry out data transmission or network side can to broadcast type that when not carrying out TTI type selecting, UE adopts or adopt the mode retrained in advance in system broadcast message, when not carrying out TTI type selecting, UE and network side arrange a kind of TTI type.

When a set of resource can only corresponding 1 TTI type time, the TTI type of the resource of signature correspondence acquiescence is determined, when network side does not allow UE to carry out TTI type selecting, UE uses 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 (such as base station) specifies UE to carry out multi-upstream access, network side (such as base station) can send the index of the signature sequence that uses at down physical channel to UE, after UE carries out TTI selection, the TTI selected in order to informing network side (such as base station) UE is 10ms TTI or 2ms is TTI, can have two ways:

First method can adopt on different PRACH channel to send the different TTI of this signature sequence in order to representative selection, this method requires that the corresponding relation of different TTI and scrambler can pre-define, also by broadcast, TTI and PRACH corresponding relation can be issued UE by network, the TTI that network side is expected to use by detecting scrambler identification UE.

Second method is that UE adopts two signature sequences to represent the TTI of 2ms or 10ms respectively, but because network side (such as base station) only specify a signature sequence to UE, therefore UE needs to determine signature sequence available in addition according to the unpaired message of signature sequence in broadcast, after UE determines these two available signature sequences, the TTI according to selecting determines to use which signature sequence.Therefore network needs the TTI information of unpaired message and correspondence thereof to send to UE by signature sequence in system broadcast message in this approach, and the signature identification UE used by detecting UE expects the TTI information that uses.

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

When network side (such as base station) allows UE to carry out the selection of resource type, issue signature 1 (or signature 2) on the hs-scch channel, if UE have selected resource type (such as 2msTTI) corresponding to signature 1 (or signature2), use signature 1 (or signature 2) to initiate Stochastic accessing; If the resource type (such as 10msTTI) that UE selects non-signature 1 (or signature 2) corresponding, then UE uses the signature 2 (or signature 1) of pairing to initiate Stochastic accessing.Now the form of HS-SCCH is:

H-RNTI

signature index1

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

Same, network side (such as base station) also can broadcast resource type corresponding to different PRACH channel in system broadcast message, such as:

When UE adopts PRACH 1 to initiate Stochastic accessing, then think that UE selects resource type one (such as: 10ms TTI);

When UE adopts PRACH 2 to initiate Stochastic accessing, then think that UE selects resource type two (such as: 2ms TTI).

Network side (such as base station) trigger UE set up standalone HS-DPCCH time, the form of HS-SCCH is as follows:

H-RNTI

signature index

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

In such scheme, network side (such as base station) can broadcast this corresponding relation in system broadcast message, and UE and network side (such as base station) further also can be adopted to make an appointment the mode of above-mentioned rule/corresponding relation.

2, after UE receives the indication information of down physical channel transmission, select resource type, the PRACH channel adopting this resource type corresponding and/or signature initiate the process of Stochastic accessing, and detect that Node B sent by down physical channel be used to indicate UE Stochastic accessing whether successfully feedback information.

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

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

When UE selects a certain resource type, Node B replys NACK at AICH, then the resource type representing UE selection is unavailable, and UE directly uses another resource type; Or

When UE selects a certain resource type, Node B indicates UE network side to allow the resource type adopted at AICH; Or

When UE selects a certain resource type, Node B specifies other resource types at EAI, and the resource that UE adopts Node B to specify carries out the foundation of HS-DPCCH feedback.

Concrete resource corresponding to above-mentioned resource type indicates before Stochastic accessing or in random access procedure by network side.

What above-mentioned access successfully referred to that UE can be clear and definite knows the resource type used when sending upstream data.

In the above-described embodiments, Node B needs whether support that TTI selects to judge the form of the down physical channel sent according to UE.Wherein the ability information of UE sends to the FP of Node B (Frame Protocol) to indicate by RNC.When UE supports TTI type selecting, RNC indicates UE to support the ability instruction of TTI type selecting in FP, for the follow-up form determining the down physical channel triggered when HS-DPCCH feedback is set up according to this indication information of Node B.

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

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

The UE be under CELL_FACH state needs to send HS-DPCCH uplink feedback, and when not having upstream data to send:

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

For example, in the present embodiment two, signature can be any one in 16 signature, does not need network side to be 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 Stochastic accessing, and detect that NodeB sent by AICH be used to indicate UE Stochastic accessing whether successfully feedback information;

3, after NodeB detects the signature of UE initiating random access procedure, in AICH, reply feedback information, whether be successfully used to indicate UE Stochastic accessing.Wherein, UE accesses successful feedback information and NACK can be adopted to represent, UE thinks after NACK being detected that employing signature initiates Stochastic accessing success.

In the present embodiment two, when adopting NACK to represent feedback information, other can be avoided to need the UE sending upstream data to select above-mentioned signature to initiate Stochastic accessing, and obtain resource corresponding to this signature.
