    • 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。

    • Transmission schemes that can flexibly achieve the desired spatial multiplexing order, spatial diversity order, and channel estimation overhead order are described. For data transmission, the assigned subcarriers and spatial multiplexing order (M) for a receiver are determined, where M = 1. For each assigned subcarrier, M virtual antennas are selected from among V virtual antennas formed with V columns of an orthonormal matrix, where V = M. V may be selected to achieve the desired spatial diversity order and channel estimation overhead order. Output symbols are mapped to the M virtual antennas selected for each assigned subcarrier by applying the orthonormal matrix. Pilot symbols are also mapped to the V virtual antennas. The mapped symbols are provided for transmission from T transmit antennas, where T = V. Transmission symbols are generated for the mapped symbols, e.g., based on OFDM or SC-FDMA. Different cyclic delays may be applied for the T transmit antennas to improve diversity.

    • Systems and methodologies are described that facilitate defining control channels and resource identifiers related thereto as well as constraints for utilizing the control channels. A minimum number of required control reports for a set of resource indices can be specified as a constraint to provide a mobile device flexibility with respect to transmitting the control reports over available resource indices. Additionally, or alternatively, a maximum number of control reports can be specified for transmitted over the resource indices to prevent control channel overload. Moreover, a constraint can specify an exact number of control channels to utilize in transmitting control reports. Other constraints are possible as well, such as limiting a control report payload or change in payload, limiting out-of-band control reports based on in-band reports transmitted, etc.

    • 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.
