Abstract: The present invention uses a portion of an orthogonal spreading code space in a CDMA spectrum for uplink signaling from a user element to a base station. By assigning the user elements one or more signaling codes, which are orthogonal to those used to spread data, to use for uplink signaling, the present invention significantly reduces interference between signaling channels, and between the data channels and the signaling channels, while supporting additional capacity. The signaling codes may be individually assigned to user elements or assigned to groups of user elements. Further, different length signaling codes may be assigned to the user elements to support different signaling rates depending on Quality of Service (QoS) requirements.

Abstract translation: 本发明使用CDMA频谱中的正交扩展码空间的一部分用于从用户单元到基站的上行链路信令。 通过为用户元件分配与用于扩展数据的那些正交的一个或多个信令码用于上行链路信令，本发明显着减少信令信道之间以及数据信道和信令信道之间的干扰，同时支持附加 容量。 信令代码可以被单独分配给用户元素或分配给用户组的组。 此外，可以将不同长度的信令码分配给用户元件，以根据服务质量（QoS）要求来支持不同的信令速率。
