摘要： A transmission method in a communications system has an orthogonal vector and a quasi orthogonal masking function for obtaining a quasi orthogonal vector from the orthogonal vector. Message signals are transmitted according to the quasi orthogonal vector. The method includes receiving the quasi orthogonal masking function and permuting the quasi orthogonal masking function to provide a further quasi orthogonal masking function. The further quasi orthogonal masking function is applied to the orthogonal vector to provide a further quasi orthogonal vector. The further quasi orthogonal vector is applied to the message signal to provide an encoded message signal for transmitting the encoded message signal within the communications system.

摘要： A method and apparatus for high data rate communication in a cellular/PCS communication system is provided. Specifically, the embodiment provides for early assignment of code channel for signaling channels (F-DCCH) in soft handoff. Thus, rather than simultaneously assigning a code channel for signaling data and another for traffic data for a particular Mobile Station (MS) in soft handoff, the code channel is assigned earlier for signaling data. Some of the unnecessary Base Station (BS) procedures with respect to the signaling data may be eliminated. An embodiment includes the concept of early signaling from the MS to request a code channel for signaling data, optionally followed by signaling (at a later time) from the MS to request a code channel for traffic data. This permits the MS to have the F-DCCH in soft handoff before having the F-DTCH (Forward Dedicated Traffic Channel) in soft handoff without requiring the BS to skip any of its procedures.
摘要翻译：提供了一种用于蜂窝/ PCS通信系统中的高数据速率通信的方法和装置。具体地，本实施例提供了在软切换中用于信令信道（F-DCCH）的代码信道的早期分配。因此，不是在软切换中同时分配用于信令数据的代码信道和另一个用于特定移动台（MS）的业务数据的代码信道，而是更早地分配用于信令数据的代码信道。可以消除关于信令数据的一些不必要的基站（BS）过程。一个实施例包括来自MS的早期信令的概念，以请求用于信令数据的码信道，可选地随后来自MS（以后的时间）从MS请求业务数据的码信道。这允许MS在具有软切换的F-DTCH（前向专用业务信道）之前使F-DCCH具有软切换，而不需要BS跳过其任何过程。
