Abstract: Early termination of enhanced multimedia broadcast-multicast service (eMBMS) is discussed. Forward error correction (FEC) redundancy data is added to broadcast data, such that if enough of the data symbols are successfully received, the data object may be reassembled before the entire transmission has been received. The aspects involve an application processor and modem processor, which may either be integrated into the same integrated circuit or separate components. The application processor obtains a total number of source symbols and a redundancy level for a data object to be received from the eMBMS, receives the successfully received data symbols from the modem processor, and then determines whether the number of successfully received data symbols exceeds a threshold for reassembling the transmitted data object. If so, then the application processor and/or the modem processor can shut down until the next broadcast.

Abstract translation: 讨论了提前终止增强型多媒体广播多播服务（eMBMS）。 向广播数据添加前向纠错（FEC）冗余数据，使得如果成功接收到足够的数据符号，则可以在接收到整个传输之前重新组合数据对象。 这些方面涉及应用处理器和调制解调器处理器，其可以被集成到相同的集成电路或单独的组件中。 应用处理器从eMBMS获得要接收的数据对象的源符号和冗余级别的总数，从调制解调器处理器接收成功接收的数据符号，然后确定成功接收的数据符号的数量是否超过阈值 用于重新组装所发送的数据对象。 如果是这样，则应用处理器和/或调制解调器处理器可以关闭直到下一个广播。

Abstract: One aspect of the present invention concerns the management of processing resource allocations for a Turbo receiver, where such resources are consumed from a finite resource budget within a defined processing time interval. The contemplated Turbo receiver attempts to allocate more processing resources to those demodulation and/or Turbo decoding tasks that make more valuable contributions with respect to the ultimate goal of successfully decoding all data streams that are of interest in a received signal. The advantageous management approach allows the Turbo receiver to obtain better results for a given consumption of processing resources, and further permits the Turbo receiver to quit upon either achieving a successful outcome within a defined processing time interval or exhausting the budgeted resources.

Abstract: There are provided a method, an apparatus and a computer program product for reducing power consumption in an iterative decoder. The apparatus includes a memory device and an iteration termination device. The memory device is for storing a bit number difference indicating a number of bits that are different between a decoded codeword for a current iteration and a decoded codeword for a previous iteration, for each iteration of the iterative decoder prior to a maximum number of iterations. The iteration termination device is for comparing the bit number difference to a pre-specified bit number difference threshold value, incrementing a confidence value when the bit number difference exceeds the pre-specified bit number difference threshold value, and terminating further iterations of the iterative decoder when the confidence value exceeds a pre-specified confidence threshold value.

Abstract: A method and an apparatus for reducing power consumption of a decoder in a communication system are disclosed. In a communication system communicating a packet, the packet can be arranged among slots of a communication channel so that each slot following the first slot contains redundant bits of the packet with respect to the first slot. A receiving station estimates metric of a received slot, determines a quality metric threshold, and delimits an interval in accordance with the modified quality metric threshold. If the estimated quality metric is outside of the interval, the segment is decoded. The decoding process comprises delimiting a plurality of intervals in accordance with the quality metric threshold, associating each of the plurality of intervals with one of a plurality of parameters, determining an interval form the plurality of intervals into which the estimated quality metric belongs; and decoding the received signal for a number of iterations equal to the one of a plurality of parameters associated with the determined interval. In the course of the decoding process, a stopping criterion is evaluated, and the decoding process is terminated in accordance with the stopping criterion.
