    摘要: This disclosure describes systems, methods, and devices related to tone mapping for a high-efficiency (HE) trigger-based (TB) null data packet (NDP) feedback physical layer protocol data unit (PPDU). A device may identify a frame received from a second device. The device may determine, based on the frame, a resource unit allocated to the device, wherein the resource unit is associated with a 20 MHz sub-channel of a bandwidth. The device may determine, based on the resource unit and the bandwidth, tones associated with a HE short training field (HE-STF) of a HE TB NDP feedback PPDU. The device may send the HE TB NDP feedback PPDU to the second device in the 20 MHz sub-channel, wherein the HE TB NDP feedback PPDU includes the tones.

    摘要: 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.

    摘要: 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.

    摘要: Methods, apparatuses, and computer readable media for location measurement reporting in a wireless network are disclosed. An apparatus of a responder station is disclosed, the apparatus comprising processing circuitry configured to derive bits from a temporary key, and generate a first sequence and a second sequence using the bits, wherein the first sequence and second sequence comprise one or more symbols. The processing circuitry is further configured to concatenate the first sequence and the second sequence to form a new first sequence comprising the first sequence and the second sequence, and concatenate a modified first sequence and a modified second sequence to form a new second sequence. The processing circuitry may be configured to repeat a number of times the concatenate the first sequence through the concatenate the modified first sequence.
