Title:
SIGNATURE SEQUENCE DISTRIBUTING METHOD ON E-HICH CHANNEL
Document Type and Number:
WIPO Patent Application WO/2008/128481
Kind Code:
A1
Abstract:
A signature sequence distributing method on E-HICH channel is provided. The
method can eliminate the unfair phenomenon brought by the code word distribution,
enable the use of the UE signature sequence used on the E-HICH channel to be uniform,
thereby enabling the average detecting performance that different UE detects
its signature sequence on E-HICH channel to be fair, and reducing the average
misdetection rate of each UE to the feedback information transmitted to itself.
The method includes the following steps: firstly, a sequence number r of the E-HICH
logic signature sequence is distributed to each UE; then the sequence number
r of the logic signature sequence is separately converted into a sequence number
r' of the physical signature sequence changed with time using a random permutation
function; afterwards, the signature sequence corresponding with the sequence
number r' of the physical signature sequence is separately distributed
to each UE.
