摘要：
When a two-dimensional spread code, with which spreading is made in time and frequency directions, is allocated to each channel, spread codes at least one of time and frequency directions of which are mutually orthogonal, and with which despreading can be made with spreading factors that are smaller than the original spreading factors in the respective directions are recognized as selection targets, and a spread code to be allocated to each channel is determined from among the spread codes recognized as the selection targets.
摘要（中）：

当将在时间和频率方向上进行扩展的二维扩展码分配给每个信道时，其时间和频率方向中的至少一个相互正交的扩频码可以通过扩频进行解扩 比各方向的原始扩展因子小的因子被识别为选择目标，从被识别为选择目标的扩展码中确定要分配给每个信道的扩展码。
