    Abstract: A communication device (alternatively, device) includes a processor configured to support communications with other communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other communication device(s) and to generate and process signals for such communications. In some examples, a device encodes information using a low density parity check (LDPC) code to generate an LDPC coded signal and transmits the LDPC coded signal to another communication device. in other examples, a device receives an LDPC coded signal from another communication device and decodes the LDPC coded signal using an LDPC matrix. The LDPC matrix includes a left hand side matrix and a right hand side matrix (e.g., having CSI (Cyclic Shifted Identity) sub-matrices on a main diagonal and another diagonal adjacently located to the main diagonal).

    Abstract: Methods, systems, and apparatuses are described for providing device(s) with additional processing time to process a packet received wirelessly while still meeting the legacy SIFS time constraint. The additional processing time may be achieved by adding, by a device transmitting the packet, padding and/or a packet extension to the last symbol of the packet. The additional processing time provided to the device(s) advantageously reduces the amount of extra hardware that would normally be added to meet the SIFS time constraint. The amount of padding and/or packet extension to be added to the last symbol is balanced to minimize the complexity of the device(s) against the reduction in system efficiency incurred by the device(s).

    Abstract translation: 描述了用于向设备提供额外的处理时间来处理在无线状态下接收的分组的方法，系统和装置，同时仍满足传统SIFS时间约束。 附加处理时间可以通过将发送分组的设备，填充和/或分组扩展添加到分组的最后一个符号来实现。 提供给设备的附加处理时间有利地减少了通常将被添加以满足SIFS时间约束的额外硬件的量。 对要添加到最后一个符号的填充和/或分组扩展的量进行平衡，以最小化设备的复杂性，从而降低由设备引起的系统效率。

    Abstract: Methods, systems, and apparatuses for opportunistic data transfer (ODT) are provided. ODT improves network coverage, reliability and/or efficiency by permitting data transfer consumers and network access providers to take advantage of communication opportunities that may be mutually beneficial. Fixed and mobile, personal or business, wired or wireless devices, may participate as ODT network operators, providers and/or consumers. ODT participants may be motivated to participate, for example, to reduce battery consumption and improve network coverage, reduce network congestion and interference. A phone, for example, may be enabled to send data to an Internet destination by ODT in lieu of a cellular network in particular circumstances, such as cellular network unavailability, with less costly data transfer and/or less battery power consumption. ODTs may be ad hoc or preauthorized and may be tracked, accounted, and compensated for, such as according to ODT service terms selected by each provider.

    Abstract: A communication device or device includes a processor that generates and interprets signals that are transmitted and received via a communication interface. The processor receives an LDPC coded signal, via the communication interface, that is generated by puncturing at least one parity bit from another LDPC coded signal that is generated based on an LDPC code characterized by a first LDPC matrix. The processor operates on the first LDPC matrix to generate a second LDPC matrix by excluding at least one column and at least one row from the first LDPC matrix. The number of columns and rows excluded from the first LDPC matrix is based on the number of bits punctured from the other LDPC coded signal to generate the LDPC coded signal. The processor then decodes the LDPC coded signal using the second LDPC matrix to make estimates of information bits encoded within the LDPC coded signal.
