摘要： A technique of mapping data, suitable for Peak to Average Power Ratio (PAPR) reduction while transmitting data portions via a communication channel limited by a peak power ppeak. The mapping is performed by utilizing a Markovian symbol transition probability distribution with quantized probabilities and by selecting, for a specific data portion at a current channel state, such a binary symbol (called thinned label) which allows puncturing one or more bits in the thinned label's bit sequence before transmission.

摘要： 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.

摘要： A time domain multiplexed (TDM) routing schedule for a wireless mesh network can be generated using a Markov chain process. In particular, synchronized paths between access nodes and gateways in the mesh network can be added to, and removed from, the TDM routing schedule in an iterative fashion according to each individual state in a state progression of a Markov chain, with each state of the Markov chain mapping a different combination of synchronized paths to the TDM routing schedule. In some embodiments, transitioning between states of a Markov chain is performed according to a proportionally fair transition rate.

摘要： 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.

摘要： Various aspects described herein relate to communicating hybrid automatic repeat/request (HARQ) feedback. HARQ feedback related to a HARQ communication over one or more links can be received from a user equipment (UE), wherein the HARQ feedback includes at least one or more interference parameters and/or one or more predicted interference parameters. A rate control loop for each of one or more interference patterns corresponding to each of the one or more links can be maintained based at least in part on the one or more interference parameters. A scheduling grant can be generated for the UE for another instance of the HARQ communication based at least in part on the rate control loop and the one or more predicted interference parameters.

摘要： 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.

摘要： Power Over Ethernet (POE)/universal power over Ethernet (UPoE) may be enabled at multigigabit port-channel connections. This may allow for additional speed support in auto-negotiation messages while employing multigigabit speeds. An integrated connector module (referred to herein as a “ICM”) compatible with UPoE with a modified local physical layer (PHY) circuit may be capable of supporting multi-gigabit data rates (such as between 1 G to 10 G, e.g., 2.5 G and 5 G) as to not limit the data rates to 1 G. The ICM may provide multi-gig data transmission through a first plurality of pins comprising a multi-gig data pin area. Furthermore, the ICM may provide UPoE power to support the multi-gig transmission through a second plurality of pins comprising a UPoE power pin area.
