Title:

INFORMAION DETECTION METHOD AND APPARATUS FOR HIGH SPEED DOWNLINK SHARED CONTROL CHANNEL

Document Type and Number:

WIPO Patent Application WO/2010/148716

Kind Code:

A1

Abstract:

An information detection method and apparatus for high speed downlink shared control channel (HS-SCCH) are provided by the present invention, implementing the detection of HS-SCCH part1 with low false alarm probability and low false dismissal probability under the arbitrary combination of the user UEID. The method is that: rate de-matching the front detection signal of each HS-SCCH channel part1 in the terminal HS-SCCH monitor set, obtaining the corresponding rate de-matched information; removing the user mask for the rate de-matched information of each HS-SCCH monitor channel; Viterbi decoding each rate de-matched information of which the user mask is removed, obtaining Viterbi decoding 0 state accumulated metric of each HS-SCCH channel in HS-SCCH monitor set, and summing the soft information absolute vale of each HS-SCCH monitor channel respectively, the soft information is obtained by removing the user mask; according to the Viterbi 0 state accumulated metric of each HS-SCCH channel and the sum of the corresponding soft information absolute values, obtaining decision vectors of each HS-SCCH channel; selecting the maximum from the decision vectors of HS-SCCH channel, comparing the maximum with the preset threshold, and judging whether the HS-SCCH channel of this user is detected.
