    摘要： A media access control (MAC) layer controller can manage base layer data and enhancement layer data in a layered modulation system. The MAC layer controller can process both base layer data and enhancement layer data and map the encoded symbols to a layered modulation constellation when both are present. If data for one of the layers terminates, then the MAC layer controller can generate and supply predetermined stuffing data to the layer lacking additional data. The MAC layer controller can send a control signal to the physical layer hardware to cause the hardware to map the layered signals having the stuffing data to a modified signal constellation. The MAC controller can also generate an overhead message that indicates the occurrence of the stuffing data. The receiver can receive the overhead message and can use the information to configure the receiver for the layered modulation constellation or the modified signal constellation.

    摘要： Techniques for transmitting overhead information to facilitate efficient reception of individual data streams are described. A base station may transmit multiple data streams on multiple data channels (or MLCs). The MLCs may be transmitted at different times and on different frequency subbands. The time-frequency location of each MLC may change over time. The overhead information indicates the time-frequency location of each MLC and may be sent as “composite” and “embedded” overhead information. The composite overhead information indicates the time-frequency locations of all MLCs and is sent periodically in each super-frame. A wireless device receives the composite overhead information, determines the time-frequency location of each MLC of interest, and receives each MLC at the indicated time-frequency location. The embedded overhead information for each MLC indicates the time-frequency location of that MLC in the next super-frame and is transmitted along with the payload of the MLC in the current super-frame.

    摘要翻译： 描述了用于发送开销信息以促进单个数据流的有效接收的技术。 基站可以在多个数据信道（或MLC）上发送多个数据流。 MLC可以在不同的时间和在不同的频率子带上传输。 每个MLC的时间 - 频率位置可能随时间而变化。 开销信息指示每个MLC的时间 - 频率位置，并且可以作为“复合”和“嵌入”开销信息发送。 复合开销信息表示所有MLC的时间 - 频率位置，并且在每个超帧中周期性地发送。 无线设备接收复合开销信息，确定感兴趣的每个MLC的时间 - 频率位置，并且在指定的时间 - 频率位置接收每个MLC。 每个MLC的嵌入式开销信息指示该MLC在下一个超帧中的时间 - 频率位置，并与当前超帧中的MLC的有效载荷一起发送。
