Abstract: Methods and apparatus for facilitating wireless communication using digital Quadrature Amplitude Modulation are disclosed. A mapping module electronic component of a wireless communication device utilizes a signal constellation for quadrature modulating a signal for transmission or quadrature demodulating a received signal. The signal constellation includes multiple constellation symbols and associated bit sequences. Specific signal constellations are disclosed. The signal constellations may be obtained through an optimization procedure which accounts for both phase noise and power amplifier nonlinearity.

Abstract: A method, node device, and system are disclosed for establishing a label switched path, which belong to the field of communications technologies. Establishing the label switched path between a source node and a sink node utilizes a connection establishment request message that carries bandwidth request information corresponding to different conditions. Based on the bandwidth request information corresponding to the different conditions, various amounts of bandwidth resources corresponding to the different conditions are reserved on local links that establish a connection between the source node and the sink node.
