    Abstract: For random linear network encoded data transmission from user equipment, a method receives a Galois field and a resource allocation for transmission of data from the user equipment. The method further encodes a first set of k data packets from a first data ensemble into a first random linear network coded (RLNC) packet as a function of the Galois field. The first RLNC packet includes an ensemble number that identifies the first data ensemble, an encoding vector, and a sequence of RLNC sub-packets. In addition, the method generates a first protocol data unit (PDU) that comprises a number of RLNC sub-packets of the first RLNC packet. A size of the first PDU does not exceed the resource allocation.

    Abstract: A plurality of interference measurements are obtained at a first communication device. The interference measurements correspond to interference experienced by the first communication device. A filter is applied to the plurality of interference measurements to obtain a filtered interference measurement, wherein the filtered interference measurement is a function of a current interference measurement and one or more past interference measurements. A channel quality indicator (CQI) corresponding to a communication channel between the first communication device and a second communication device is determined based at least in part on the filtered interference measurement. The CQI is transmitted from the first communication device to the second communication device.

    Abstract: A method for calibrating rates at which data is transmitted in a communication system. There is a short transmission utilizing a first set of communication parameters comprising first and second communication parameters. The first set of communication parameters are different from the second set of communication parameters used to create stable communication between the transmitter and receiver. The second set of communication parameters comprise first and second communication parameters. Then determining that there are substantially no errors associated with reception of the short transmission by the receiver. Then transmitting a long transmission utilizing a third set of communication parameters comprising first and second communication parameters. The first communication parameter of the third set is equal to the first communication parameter of the first set. The second communication parameter of the third set is equal to the second communication parameter of the second set.

    Abstract: Applicants have discovered that error detection techniques, such as Forward Error Correction techniques, may be used to predict the degradation below a certain threshold of an ability to accurately convey information on a communication channel, for example, to predict a failure of the communication channel. In response, transmission and/or reception of information on the channel may be adapted, for example, to prevent the degradation below the threshold, e.g., prevent channel failure. Predicting the degradation may be based, at least in part, on data transmission error information corresponding to one or more blocks of information received on the channel and may include determining an error rate pattern over time. Based on these determinations, the degradation below the threshold may be predicted and the transmission and/or reception adapted. Adapting may include initiating use of a different error encoding scheme and/or using an additional communication channel to convey information.
