20100094995 | Silent Probes in a Communication Network - A system, device and process to enable a “silent probe” on a network to facilitate network analysis by nodes within a network. A network node requests the silent probe. During the silent probe, all nodes remain silent so that all nodes can listen, hear, and/or analyze the spectrum of the communications medium. | 04-15-2010 |
20100150016 | Receiver Determined Probe - According to various embodiments of the disclosed method and apparatus, nodes on a network are programmed to generate a probe transmission in response to a request from the node that will be receiving the probe. The receiving node may generate a probe request that specifies a plurality of parameters, such as a modulation profile for the probe; the payload content of the probe; the number of times to transmit the probe; a number of symbols for the payload of the probe; a preamble type for the probe; a cyclic-prefix length for the payload of the probe; a transmit power for the probe; and a transmit power scaling factor for the payload of the probe. | 06-17-2010 |
20110007731 | Method and Apparatus for LDPC Transmission Over a Channel Bonded Link - A particular overall architecture for transmission over a bonded channel system consisting of two interconnected MoCA (Multimedia over Coax Alliance) 2.0 SoCs (“Systems on a Chip) and a method and apparatus for the case of a “bonded” channel network. With a bonded channel network, the data is divided into two segments, the first of which is transported over a primary channel and the second of which is transported over a secondary channel. | 01-13-2011 |
20110182199 | Method and Apparatus for use of Silent Symbols in a Communications Network - Systems and methods for characterizing a communication channel including transmitting silent symbols during periods of a packet. | 07-28-2011 |
20110216776 | METHOD AND APPARATUS FOR ASYNCHRONOUS ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS - A method of transmitting orthogonal frequency division multiple access signals includes transmitting a first stream of data from a first node of a network. The first stream includes a preamble and payload. A second stream of data is transmitted from a second node of the network. The second stream includes a preamble and payload, and the second stream has a shorter total length than the first stream. The transmission of the second stream starts at essentially the same time as the transmission of the first stream. A third stream of data is transmitted from the second node of the network. The third stream includes a preamble and payload. The transmission of the third stream begins at the end of the payload of the second stream and prior to the end of the transmission of the remainder of the payload of the first stream. | 09-08-2011 |
20110216781 | Method and Apparatus for Asynchronous Orthogonal Frequency Division Multiple Access - A method of transmitting orthogonal frequency division multiple access (OFDMA) signals includes transmitting, at a first transmitter of a network, a first stream of data having a first number of symbols over a first time interval using a first set of one or more OFDMA subcarriers. At a second transmitter of the network, a second stream of data is transmitted having a second number of symbols over a second time interval, different in duration than the first time interval and overlapping the first time interval. The second burst of data is transmitted using a second set of one or more OFDMA subcarriers. The first time interval and first set of subcarriers define a first time-frequency grant, the second time interval and second set of subcarriers define a second time-frequency grant, and the first and second time-frequency grants are granted by a network coordinator node of the network. | 09-08-2011 |
20110305157 | Method and Apparatus for Preamble Reduction - A method of reducing resource overhead attributed to preambles in a communication system includes transmitting, at a transmitter, one or more signals including a first packet. The first packet is transmitted in a first time-frequency grant including a first set of one or more subcarriers. The first packet includes a full preamble including reference signal information for determining a total channel estimate for every subcarrier to be used in transmission of the first packet. A second packet is transmitted in a second time-frequency grant including a second set of one or more subcarriers without a full preamble when a receiver configured to communicate with the transmitter can determine a phase offset between the transmitter and the receiver from the signals received at the receiver. | 12-15-2011 |
20120008640 | Method and Apparatus for Using Dynamic Subchannels in a Communications Network - A method and apparatus for attaining the benefits of both an adjacent subchannel assignments and distributed subchannel assignments. That is, the following is a method and apparatus for providing dynamic subchannel assignments that provide the benefits of both adjacent subchannel assignments and distributed subchannel assignments. | 01-12-2012 |

20130315595 | TIME DIVISION DUPLEXING FOR EPoC - A method, system and computer program for implementing TDD in an EPoC network. An OLT or CLT scheduler segregates the US traffic from the DS traffic to avoid collisions. An OLT transmits and receives payloads through an OCU. An OLT or CLT transmits downstream payloads and GATE grants destined for CNUs during the TDD downstream phases. The OLT or CLT schedules IPGs between TDD phases. The OLT or CLT schedules payloads and REPORTs to be transmitted from CNUs only during the TDD upstream phase according to the GATE grants in the DS phase. The OLT or CLT receives CNU REPORTs late in the upstream phase that inform the scheduler about pending upstream traffic to be granted in subsequent TDD phases. | 11-28-2013 |
