    • A shared signaling channel can be used in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system to provide signaling, acknowledgement, and power control messages to access terminals within the system. The shared signaling channel can be assigned to a predetermined number of sub-carriers within any frame. The assignment of a predetermined number of sub-carriers to the shared signaling channel establishes a fixed bandwidth overhead for the channel. The actual sub-carriers assigned to the channel can be varied periodically, and can vary according to a predetermined frequency hopping schedule. The amount of signal power allocated to the signaling channel can vary on a per symbol basis depending on the power requirements of the communication link. The shared signaling channel can direct each message carried on the channel to one or more access terminals. Unicast messages allow the channel power to be controlled per the needs of individual communication links.
    • 共享信令信道可用于正交频分多址(OFDMA)通信系统中,以向系统内的接入终端提供信令,确认和功率控制消息。 共享信令信道可以被分配给任何帧内的预定数量的子载波。 将预定数量的子载波分配给共享信令信道为该信道建立固定的带宽开销。 分配给信道的实际子载波可以周期性地变化,并且可以根据预定的跳频时间表而变化。 根据通信链路的功率需求,分配给信令信道的信号功率的量可以根据每个符号而变化。 共享信令信道可以将信道上承载的每个消息引导到一个或多个接入终端。 单播消息允许按照各个通信链路的需要来控制信道功率。

    • Signaling is efficiently sent on a configurable CDMA control segment. To send signaling, transmission parameters for the CDMA control segment for a serving sector are determined. These parameter may indicate the CDMA control segment size, the frames in which the CDMA control segment is sent, the signaling channels to be sent on the CDMA control segment, and so on. The enabled CDMA signaling channels for a terminal and the average transmission interval for each enabled CDMA signaling channel are determined. For each frame in which the CDMA control segment is sent, the signaling channels to be sent on the CDMA control segment in that frame are determined. The signaling for each signaling channel is processed (e.g., encoded, channelized, scaled, and scrambled). The processed signaling for all signaling channels is combined and mapped to a time-frequency region used for the CDMA control segment in the frame.
    • 在可配置的CDMA控制段上有效地发送信令。 为了发送信令,确定用于服务扇区的CDMA控制段的传输参数。 这些参数可以指示CDMA控制段大小,发送CDMA控制段的帧,在CDMA控制段上发送的信令信道等等。 确定终端的使能的CDMA信令信道和每个使能的CDMA信令信道的平均传输间隔。 对于其中发送CDMA控制段的每个帧,确定要在该帧中的CDMA控制段上发送的信令信道。 处理每个信令信道的信令(例如,编码,信道化,缩放和加扰)。 所有信令信道的经处理的信令被组合并映射到帧中用于CDMA控制段的时间 - 频率区域。
