摘要： Methods and systems are provided for mitigating noise and/or impedance effects in transmitters. The mitigation comprises, when transmitter is in a non-active mode, decoupling at least a portion of the transmitter and coupling an auxiliary component to a remaining portion of the transmitter. When the transmitter is in an active mode, the auxiliary component is decoupled from the remaining portion of the transmitter, and the at least a portion of the transmitter is coupled to the remaining portion of the transmitter. The auxiliary component comprises one or more of: a resistive element, a capacitive element, and a reactive component. The auxiliary component is configured such that it may achieve a small mismatching error.

摘要： The disclosed method and apparatus provides systems, methods, and apparatuses for implementing a PQoS flow between two or more nodes located in different network segments of a multi-segment network, when some nodes involved in the flow lack support for high layer QoS management protocols. Specifically, some embodiments are directed toward implementing a PQoS flow involving some nodes that lack network layers higher than a Data Link Layer (layer 2). For example, some embodiments of the current disclosed method and apparatus can create a parameterized QoS flow between a source node and a destination node when at least one of the nodes participating in the flow (i.e. the source node, one or multiple bridge nodes that the QoS flow passes, and the destination node) lacks UPnP QoS Device Services (i.e., a higher layer QoS management protocol).

摘要： 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.
