    • A method, system and apparatus for spreading physical channels (210) using partly orthogonal multiplecode trees(300). A portion of a first code tree is used to spread the physical channels. This first code tree is a combination of a channelization code sequence (825A,870A,875A) and a first scrambling code sequence. A portion of a second code tree (350) is used to spread the physical channels that are remaining and were not spread using the first code tree (310). This second code tree (350) is a combination of the channelization code sequence (825A,870A,875A) and a second scrambling code formed by modifying the first scrambling code. The portion of the second code tree (350) used to spread the channels is orthogonal to the portion of the first code tree (310) used. A plurality of other code trees (300) could be formed using scrambling codes based on the modification of the first scrambling code.
    • 一种用于使用部分正交多码树(300)扩展物理信号(210)的方法,系统和装置。 第一代码树的一部分用于扩展物理通道。 该第一码树是信道化码序列(825A,870A,875A)和第一扰码序列的组合。 使用第二代码树(350)的一部分来扩展剩余的并且不使用第一代码树(310)传播的物理信道。 第二代码树(350)是信道化码序列(825A,870A,875A)和通过修改第一扰码形成的第二扰码的组合。 用于扩展信道的第二代码树(350)的部分与所使用的第一代码树(310)的部分正交。 可以使用基于第一扰码的修改的扰码来形成多个其他码树(300)。
