  • Publication number: 20240137154
    Abstract: A station (STA) configured for operation in a WLAN may perform bit scrambling on input bits to generate scrambled input bits and may perform probabilistic constellation shaping using a shaping encoder on the scrambled input bits. The shaping encoder may encode a segment of the scrambled input bits for a modulation order and generate a shaped bit stream. In these embodiments, the STA may generate a QAM symbol stream with a QAM modulator. The QAM symbol stream may be generated at least from the shaped bit stream and from parity bits using the modulation order. The STA may generate the parity bits from the shaped bit streams with a forward-error correction (FEC) encoder and may transmit the QAM symbol stream within a physical layer protocol data unit (PPDU). To address a potential byte boundary shift caused a decoding error at a receiving station, the STA may modify performance of the bit scrambling when probabilistic constellation shaping is performed.

    Abstract: An apparatus and method of signaling coding type is disclosed. The coding types include binary convolutional coding (BCC), legacy lifted Low-Density Parity Check (LDPC) code, and lifted LDPC code having a length that is a multiple of the maximum legacy LDPC code. The number of bits used to indicate the coding type in a User Info field depends on whether multiple lifted LDPC codes are available for encoding, whether the lifted LDPC code is an optional coding type, or a payload size. The frame containing the User Info field is transmitted to another STA and the response contains a payload encoded using the indicated coding type.

  • Publication number: 20240048271
    Abstract: An apparatus and method of encoding Low-Density Parity Check (LDPC) Physical Layer Convergence Protocol (PLCP) packet protocol data units (PPDU) is disclosed. For LDPC codeword of lengths 3888 and/or 7776, the number and length of codewords to use may depend on the number of available bits. In this case, if the number of available bits is larger than 1944 and less than 2596, two codewords of length 1944 or a single codeword of length 3888 to encode the PPDU is used to encode the PPDU. For larger numbers of available bits, one or more codewords of length 3888 or 7776 is used to encode the PPDU. Shortening and/or puncturing, when used, is also based on the number of available bits.

  • Patent number: 11864027
    Abstract: An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate, The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.

  • Publication number: 20230397249
    Abstract: An access point station (AP) configured for ultra-high reliability (UHR) communication in a wireless local area network (WLAN) may receive low-latency (i.e., time-sensitive) traffic during a transmission opportunity (TXOP) by transmission of an initial frame encoded to indicate whether or not preemption for low-latency (LL) traffic is enabled during the TXOP. When preemption for LL traffic is enabled during the TXOP, the AP may encode downlink (DL) physical-layer protocol data units (PPDUs) for transmission within the TXOP. The DL PPDUs may be transmitted with an extended short interframe spacing (xIFS) therebetween. Each of the DL PPDUs may indicate whether the xIFS that follows a DL PPDU is enabled for preemption.

  • Patent number: 11812385
    Abstract: An apparatus for implementing power control for a radio device that has multiple radio transceivers operating in different bands, including sub-bands of a single frequency band. The device implements a power control protocol for communications between the device and a similar peer device. The device sets-up the power control protocol by generating a request to use one of the multiple bands to signal power control operations, and to use another one of the multiple bands to transfer data between the device and the peer device. The device sends the request to the peer device and receives a response. Based on the response, the device identifies a control channel band and a data channel band from among the multiple bands.

  • Patent number: 11805561
    Abstract: Multi-link device (MLD) devices and transitions are described. The MAC addresses of the AP MLD and non-AP MLD are used to generate keys for different fast transitions (FT) between a non-AP MLD and an AP MLD. In an FT initial mobility domain operation, the AP MLD MAC address is used as the R1KH-ID and the non-AP MLD MAC address is used as the S0KH-ID and S1KH-ID. The MAC addresses are exchanged in Authentication Request/Response or Association Request/Response messages and the GTK/IGTK/BIGTK are delivered in a single FT 4-way handshake. In a fast MLD transition to an AP MLD in the same ESS, the other AP MLD MAC address is used as the R1KH-ID and the non-AP MLD MAC address is used as the S1KH-ID. The MAC addresses are exchanged in Authentication Request/Response or Association Request/Response messages and the GTK/IGTK/BIGTK are delivered in an FTE.
