    • A retransmission method maps at least some bits of codeword to symbols according to a first modulation method at the time of first transmission. The retransmission method maps at least some bits of the codeword to symbols according to a second modulation method that is different from the first modulation method at the time of second transmission after the first transmission. In this case, the second modulation method may have a lower modulation order than that of the first modulation method, or a sum of average reliability per bit of symbol according to the second modulation may be larger than a sum of average reliability per bit of symbol according to the first modulation method.
    • 在第一次发送时,重发方法将码字的至少一些比特根据第一调制方法映射到符号。 根据在第一次传输之后的第二次发送时与第一调制方法不同的第二调制方法,重传方法将码字的至少一些比特映射到符号。 在这种情况下,第二调制方法可以具有比第一调制方法更低的调制次序,或者根据第二调制的符号的每比特的平均可靠性的总和可以大于符号的每比特的平均可靠性的总和 根据第一调制方式。

    • A sliding/swing-type portable digital communication apparatus is disclosed. A first housing extends in a longitudinal direction and includes a camera lens housing mounted on its bottom surface and at least one speaker unit positioned adjacent to the camera lens housing. A second housing is adapted to slide/swing while continuously facing a top surface of the first housing and is disposed parallel to the first housing along the longitudinal direction. A cover is coupled to a portion of the bottom surface of the first housing and is adapted to slide along the longitudinal direction. An opening is formed on the cover to selectively expose or hide the camera lens housing or the first speaker units according to whether or not the cover has been slid.
    • 公开了一种滑动摆动型便携式数字通信装置。 第一壳体在纵向方向上延伸并且包括安装在其底表面上的照相机镜头壳体和邻近相机镜头壳体定位的至少一个扬声器单元。 第二壳体适于在连续面对第一壳体的顶表面的同时滑动/摆动,并且沿纵向平行于第一壳体设置。 盖子耦合到第一壳体的底表面的一部分并且适于沿着纵向方向滑动。 根据盖是否滑动,在盖上形成开口以选择性地暴露或隐藏相机镜头壳体或第一扬声器单元。
