Abstract: This disclosure describes systems, methods, and devices related to enhanced constellation shaping. A device may generate payload bits associated with a frame, wherein the payload bits comprise a first portion and a second portion. The device may send the first portion of the payload bits through a shaping encoder. The device may generate shaped bits from the shaping encoder. The device may determine a number of amplitude bits based on the shaped bits. The device may generate parity bits from the shaped bits and the second portion going through an low-density parity-check (LDPC) encoder. The device may select sign bits comprising the second portion and a first subset of the parity bits. The device may send the amplitude bits with the sign bits to a modulator before transmitting the frame to a first station device.

Abstract: This disclosure describes systems, methods, and devices related to enhanced constellation shaping. A device may generate payload bits associated with a frame to be sent to a first station device. The device may generate a first output bits having a first length based on the application of a first mask of one or more masks to the payload bits. The device may generate a second output bits having a second length based on the application of a second mask of the one or more masks. The device may compare the first length of the first output bits to the second length of the second output bits. The device may select the first mask or the second mask based on the comparison. The device may convert the payload bits using the selected mask before passing through a shaping encoder to generate shaped bits. The device may cause to send the frame bits and an indication of the selected mask to the first station device.

Abstract: This disclosure describes systems, methods, and devices related to fixed-to-fixed shaping encoding. A device may determine a mapping table associated with uniformly distributed bits into amplitudes with desired probabilities. The device may predict a number of output bits for an input block. The device may apply padding as needed based on the predicted number of output bits.

Abstract: An apparatus for a station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN) comprises the processing circuitry configured to modify probabilities of constellation points to generate a more Gaussian distribution. In these embodiments, for LDPC framing and OFDM packing, the transmitter circuitry may be configured to compute a number of output bits (bout) to be transmitted based on a number of payload bits (bin) at an output of a shaping encoder, a shaping rate (rshaping), and an overhead percent (Boverhead). A shaping gain of up to 1.53 dB may be achieved. A new shaping encoder is provided to address the issue that the number of bits is not fixed.

Abstract: For example, a wireless communication receiver may be configured to switch one or more RF components of the receiver between an on-state and an off-state based on at least one detection criterion for preamble detection of a frame preamble by a preamble detector of the receiver, switching the one or more RF components between the on-state and the off-state including switching the one or more RF components from the on-state to the off-state based on determination that the at least one detection criterion is not met, and switching the one or more RF components from the off-state to the on-state after an off-state period, wherein a duration of the off-state period is based at least on a preamble duration of the frame preamble; and to repeat switching the one or more RF components between the on-state and the off-state until the frame preamble is detected by the preamble detector.
