    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: In an uplink service transmission method, an access point divides an entire channel into resource blocks according to a quantity of stations that are connected to the access point, then allocates, to each station according to channel estimation information of each station, a resource block used to transmit uplink information, and separately sends channel allocation indication information to each station, so that each station finds, according to the channel allocation indication information, the resource block corresponding to the station, and transmits the uplink information by using the resource block, so as to implement that in an OFDMA system, multiple stations transmit uplink information in parallel, that is, resource blocks that are obtained by means of division can be simultaneously applicable to multiple stations.

    Abstract: An environmental imaging method includes: A first device sends first indication information to a second device, where the first indication information indicates a first spatial location at which the second device is to send a measurement signal, and the first spatial location is evenly distributed in an azimuth direction and/or at an azimuth angle; the first device receives an echo signal, where the echo signal is a signal formed by reflecting, by a target, the measurement signal sent by the second device after the measurement signal arrives at the target; and the first device performs imaging on the target based on the echo signal. The method may be implemented in a system or an apparatus.
