Receive after the E-PUCH d, base station, the processing of decoding, 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-HICH Indicator, E-HICH indication) indication.Specifically, before transfer of data, network side is by RRC (Radio Resource Control, Radio Resource control) signaling is that UE disposes maximum four E-HICH, 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 which the bar E-HICH in four is fed back 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 80 rank, when ACK/NACK encodes, certain delegation's 80 long sequence of taking-up from this orthogonal matrix (C80,
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 code sequence of residential quarter 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:

q
0Be t
0Minimum channel code in the time slot number (1,2 ..., Q
0);
Q
0Be t
0The spread spectrum coefficient of time slot minimum channel code 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 minute 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, be the different midamble window of the user assignment of sharing E-PUCH resource, thereby further improve channel estimating performance and link performance.
