Abstract: Techniques for multiplexing and transmitting multiple data streams are described. Transmission of the multiple data streams occurs in “super-frames”. Each super-frame has a predetermined time duration and is further divided into multiple (e.g., four) frames. Each data block for each data stream is outer encoded to generate a corresponding code block. Each code block is partitioned into multiple subblocks, and each data packet in each code block is inner encoded and modulated to generate modulation symbols for the packet. The multiple subblocks for each code block are transmitted in the multiple frames of the same super-frame, one subblock per frame. Each data stream is allocated a number of transmission units in each super-frame and is assigned specific transmission units to achieve efficient packing. A wireless device can select and receive individual data streams.

Abstract translation: 描述用于复用和传输多个数据流的技术。 多个数据流的传输发生在“超帧”中。 每个超帧具有预定的持续时间并进一步分为多个（例如，四个）帧。 每个数据流的每个数据块被外部编码以生成相应的代码块。 每个码块被划分成多个子块，并且每个码块中的每个数据分组被内部编码和调制以产生分组的调制符号。 每个码块的多个子块在相同超帧的多个帧中传送，每帧一个子块。 每个数据流在每个超帧中被分配多个传输单元，并被分配特定的传输单元以实现有效的打包。 无线设备可以选择和接收各个数据流。

Abstract: Techniques are provided for smooth transition between broadcast/multicast transmission and unicast transmission. A method for managing unicast and multicast services switching in a multi-band/multi-frequency wireless communications system (WCS) capable of both unicast and multicast signaling includes determining whether an aggregate demand for a content provided via dedicated unicast transmissions exceeds a threshold. The method includes switching transmission of the content from the dedicated unicast transmissions on one frequency to a multicast transmission on a second or more frequencies in response to determining that the aggregate demand exceeds the threshold.
