Description
Technical field
The present invention relates to the communication technology, be specifically related to a kind of feedback method, system and equipment of multi-user sharing physical resources.
Background technology
HSUPA (High Speed Uplink Packet Access, High Speed Uplink Packet inserts) be 3GPP (Third Generation Partnership Project, the 3G (Third Generation) Moblie partnership projects) a kind of up enhanced scheme of Ti Chuing strategy such as shares to reach the maximization uplink throughput by code channel resource, power resource.
The transfer of data of HSUPA is divided into scheduled transmission and non-scheduled transmission.The flow process of scheduled transmission is as shown in Figure 1:
Have uplink strengthening data etc. to be sent in a, the UE buffer memory, UE sends E-RUCCH (E-DCHRandom access Uplink Control Channel, E-DCH insert ascending control channel at random), the request scheduling resource;
Scheduling of resource is carried out according to the dispatch request information of receiving in b, base station, and goes up the transmission resource license information at E-AGCH (E-DCHAbsolute Grant Channel, E-DCH absolute grant channel);
C, UE are according to the resource scheduling information of receiving, strengthening transformat combination (E-TFC) selects, select suitable TBS (Transport Block Size, the transmission block size) and modulation system, encode afterwards, modulate, go up the transmission uplink strengthening data at E-PUCH (E-DCH Physical Uplink Channel, E-DCH physical uplink channel);
Receive after the E-PUCH d, base station, carry out decoding processing, obtain ACK/NACK information according to CRC check, coding is mapped on the E-HICH (E-DCH HARQ acknowledge Indicator Channel, E-DCH HARQ answering indication signal channel) and feeds back to this UE afterwards;
Like this, UE has just finished the data transmission of a scheduled transmission process.
Wherein, the E-HICH physical channel of feedback is by 2 bit EI on the E-AGCH (E-HICHIndicator, E-HICH indication) indication.Specifically, before transfer of data, network side is that UE disposes maximum four E-HICH by RRC (Radio Resource Control, Radio Resource control) signaling, and be numbered respectively, indicate physical resource and training sequence (midamble) assignment information of each bar E-HICH.The base station indicates this time transmission to feed back on which the bar E-HICH in four by the EI on the E-AGCH.
ACK/NACK coding method on the E-HICH is the orthogonal sequence XOR with the ACK of 1 bit or nack message and 80 bit long.Wherein, orthogonal sequence is obtained by E-PUCH shared physical resource and a fixing randomisation process.Specifically, agreement has been stipulated the orthogonal matrix C80 on one 80 rank, when ACK/NACK encodes, takes out certain 80 long sequence (C80 of delegation from this orthogonal matrix
, r ', n), wherein, the r ' of r ' expression 80 rank orthogonal matrixes is OK.R ' is obtained by a randomisation process by r.(MidambleCode), wherein SFN ' is system's subframe numbers of E-HICH to r '=P for r, SFN ', and MidambleCode is the basic Midamble sign indicating number sequence of sub-district appointment, and P is a pseudo random sequence.
R is logical resource label ID, has mapping relations with the shared physical resource of E-PUCH:
Wherein:
t
0For distributing the last time slot in the time slot, promptly maximum timeslot number (1,2 .., 5);
q
0Be t
0Minimum channel sign indicating number in the time slot number (1,2 ..., Q
0);
Q
0Be t
0The spread spectrum coefficient of time slot minimum channel sign indicating number number employing.
The mapping relations of logical resource label ID and the shared physical resource of E-PUCH as shown in Figure 2.
For example, the shared physical resource of E-PUCH is the code channel of the 1st SF=4 of time slot 1 and time slot 2, and then corresponding r should be 16.
For resource utilization and the uplink throughput that improves system, can utilize empty branch technology, give different users with identical up E-PUCH physical source distributing.Utilize the isolation in its space, these users performance separately is guaranteed.Such as, can be that a plurality of users send dispatching command by E-AGCH respectively, and for they distribute identical E-PUCH physical resource.Described E-AGCH form can be form of the prior art.In order further to improve performance, can also change the E-AGCH form, carry the information of midamble window thereon, for the user of sharing E-PUCH resource distributes different midamble windows, thereby further improve channel estimating performance and link performance.
Yet according to the feedback system of scheduled transmission in the prior art, during for certain scheduled transmission user feedback, the feedback information employed orthogonal sequence of encoding is determined by the E-PUCH physical resource.If distributed identical E-PUCH physical resource, then can't use identical E-HICH to feed back respectively for these users simultaneously, thereby cause empty branch technology can't be applied to the HSUPA system for a plurality of users.

Embodiment
In order to make those skilled in the art person understand the scheme of the embodiment of the invention better, the embodiment of the invention is described in further detail below in conjunction with drawings and embodiments.
The feedback method of embodiment of the invention multi-user sharing physical resources, in the system of scheduled transmission, utilize empty branch technology, give different users with identical E-PUCH physical source distributing, make these user's sharing E-PUCH physical resources, when being a plurality of user feedback of sharing E-PUCH physical resource, use different orthogonal sequences that the feedback information of corresponding different user is encoded, and the feedback information after will encoding is mapped to the user who feeds back to correspondence on the same E-HICH; Perhaps use identical orthogonal sequence that the feedback information of corresponding different user is encoded, and the feedback information after will encoding is mapped to the user who feeds back to correspondence on the different E-HICH.Thereby make empty branch technology can be applied to system better, improve system physical resource utilization and uplink throughput.
Correspondingly, at user side,, determine orthogonal sequence according to the announcement information of network side at the situation of multiple users share E-PUCH physical resource; After sending uplink strengthening data on the E-PUCH physical resource of network side configuration, according to described orthogonal sequence the E-HICH that receives is decoded, obtain network side to receiving the feedback information of described uplink strengthening data.
As shown in Figure 3, be a kind of flow chart of the feedback method of embodiment of the invention multi-user sharing physical resources, may further comprise the steps:
Step 302 is according to the orthogonal sequence of each user among the definite corresponding described a plurality of users of the configuration information of network side, the orthogonal sequence difference of different user correspondence.
The configuration information of network side can have multiple, and correspondingly, corresponding different configuration informations also can have multiple mode when determining each corresponding user orthogonal sequence.
Such as, network side is that described a plurality of user disposes the orthogonal sequence side-play amount respectively, like this, and just can be according to the orthogonal sequence of each user among described orthogonal sequence side-play amount and the definite corresponding described a plurality of users of described E-PUCH physical resource.Particularly, can determine an orthogonal sequence according to the mapping relations of E-PUCH physical resource and orthogonal sequence earlier, then on the basis of the sequence number of this orthogonal sequence, the side-play amount that adds configuration is determined the sequence number of the orthogonal sequence that uses, finds corresponding orthogonal sequence according to this sequence number again.
When concrete the application, described side-play amount can dispose and be notified to the base station by RNC (radio network controller), and is notified to the user by RRC (Radio Resource control), also can be by base station configuration, and be notified to the user by E-AGCH.When by E-AGCH the side-play amount that disposes being notified to the user, can on E-AGCH, increase the information field of an orthogonal sequence sequence number skew by the base station.The base station when this user is dispatched, by this information field on the E-AGCH, the side-play amount of the orthogonal sequence that when feedback indication uses, and the E-PUCH physical resource that distributes according to this side-play amount and for the user is definite to orthogonal sequence that should the user.

Further, during for this user feedback, whether use this side-play amount, the base station can be indicated to the user by the information on the physical control channel E-AGCH.For example, when the base station uses traditional E-AGCH form to dispatch, can adopt the mode of prior art to determine the orthogonal sequence that feedback is used; When form is dispatched, can determine orthogonal sequence and use new E-AGCH (explicit or implicit expression carries the information that this side-play amount is used in indication) according to this side-play amount when the base station.
For another example, network side is the sequence number that described a plurality of user distributes different orthogonal sequences, like this, directly obtains corresponding wherein each user's orthogonal sequence according to the sequence number of described orthogonal sequence.
When concrete the application, the sequence number of described orthogonal sequence can be distributed and informing base station by RNC, and is notified to the user by RRC (Radio Resource control).Also can be by base station configuration, and be notified to the user by E-AGCH.Particularly, can increase the information field of an orthogonal sequence sequence number on E-AGCH, the base station is when dispatching certain user, by this information field on the E-AGCH, the sequence number of the orthogonal sequence that uses when notifying this user feedback.

The configuration information of network side can have multiple, and correspondingly, network side notifies user's mode also can have multiple described configuration information.
Such as, network side is that described a plurality of user has disposed the orthogonal sequence side-play amount respectively, can be with this side-play amount by the corresponding user of radio resource control signaling notice, perhaps by the corresponding user of E-AGCH notice.
For another example, network side is the sequence number that described a plurality of user has distributed orthogonal sequence respectively, can notify corresponding user by radio resource control signaling or by E-AGCH with the sequence number of this orthogonal sequence.
In the above-described embodiments, the process that sends at multiple users share E-PUCH physical resource situation lower network side feedback information has been described.
Correspondingly, at user side, the user can determine orthogonal sequence according to the announcement information of network side; After sending uplink strengthening data on the E-PUCH physical resource of network side configuration, according to described orthogonal sequence the E-HICH that receives is decoded, obtain network side to receiving the feedback information of described uplink strengthening data, described E-PUCH physical resource is that a plurality of users share.
With reference to Fig. 4, be the another kind of flow chart of the feedback method of embodiment of the invention multi-user sharing physical resources, may further comprise the steps:
Step 401 is determined orthogonal sequence according to the announcement information of network side.
The announcement information of described network side can be the orthogonal sequence side-play amount that network side passes through RNC signaling or E-AGCH notice, and like this, user side can be determined orthogonal sequence according to described orthogonal sequence side-play amount and described E-PUCH physical resource.Detailed process determines that with previously described network side the process of orthogonal sequence is identical, does not repeat them here.
The announcement information of described network side can also be the sequence number that network side passes through radio resource control signaling or the orthogonal sequence by E-AGCH notice, and like this, user side can be determined orthogonal sequence according to described sequence number.Detailed process determines that with previously described network side the process of orthogonal sequence is identical, does not repeat them here.
