    • An information detection method and apparatus for a High Speed Downlink Shared Control Channel (HS-SCCH) are provided by the present disclosure, implementing the detection of HS-SCCH part1 with low false alarm probability and low false dismissal probability under the arbitrary combination of User Identifiers (UEID). The method is that: rate de-matching the front detection signal of each HS-SCCH 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 in HS-SCCH monitor set, and summing the absolute value of the soft information of each HS-SCCH monitor channel respectively, with the soft information being obtained by removing the user mask; according to the Viterbi 0 state accumulated metric of each HS-SCCH and the sum of absolute values of the corresponding soft information, obtaining determination variables of each HS-SCCH; selecting the maximum from the determination variables of HS-SCCH, comparing the maximum with the preset threshold, and determining whether the HS-SCCH of this user is detected.

    • An arrangement and method for channel mapping in a UTRA TDD HSDPA wireless communication system by applying interleaving functions in first (530) and second (540) interleaving means to a bit sequence to produce symbols for mapping to physical channels, the first and second interleaving means being arranged to map symbols from respectively systematic and parity bits in a predetermined scheme, e.g., mapping symbols in a forward direction when a channel has an even index number, and in a reverse direction when a channel has an odd index number. The symbols may comprise bit-pairs, each of a systematic bit and parity bit.Systematic bits are preferably mapped to high reliability bit positions in TDD HSDPA, achieving a performance gain of between 0.2 dB and 0.5 dB. The forwards/reverse mapping allows a degree of interleaving that improves system performance in fading channels or channels disturbed by short time period noise or interference.
    • 一种在UTRA TDD HSDPA无线通信系统中通过将第一(530)和第二(540)交织装置中的交织功能应用于比特序列以产生用于映射到物理信道的符号的信道映射的装置和方法,所述第一和第二交织装置 被布置成以预定方案映射来自分别系统和奇偶校验位的符号,例如当信道具有偶数索引号时向前方映射符号,以及当信道具有奇数索引号时,反向方向。 符号可以包括位对,系统位和奇偶校验位中的每一个。 系统位优选地映射到TDD HSDPA中的高可靠性位位置,实现0.2dB至0.5dB之间的性能增益。 前向/反向映射允许一定程度的交织,改善由短时间间隔噪声或干扰而干扰的衰落信道或信道中的系统性能。
