An apparatus used in a non-Access Point Station (non-AP STA), includes processor circuitry configured to cause the non-AP STA to, when there is urgent data that must be transmitted in uplink without waiting for a scheduled slot: generate a Protocol Data Unit (PDU) from the urgent data; and transmit the PDU on a resource unit pre-assigned for urgent transmission, wherein the resource unit is multiplexed for uplink transmission from multiple non-AP STAs.

A device may utilize a tone plan to generate an EHT frame to be sent using an 80 MHz frequency band, wherein the tone plan comprises a plurality of null tones. The device may encode one or more resource units (RUs) for the EHT frame, wherein the one or more RUs comprise at least one of a 26-tone RU, a 52-tone RU, a 106-tone RU, a 242-tone RU, a 484-tone RU, or a 996-tone RU, wherein the 106-tone RU, the 242-tone RU, and the 484-tone RU comprise null tones located at least at subcarriers ±258, ±257, ±256, ±255, and ±254. The device may cause to send the EHT frame to a first station device using the 80 MHz frequency band.

Extreme high throughput resource unit allocation table

Logic may enable client devices or access points to relay medium access control (MAC) frames through a Wireless Fidelity (Wi-Fi) Direct network such as a network of Peer-to-Peer (P2P) connections to extend the wireless range of the devices or access points beyond the transmission range of the individual devices or access points. Logic may extend the range of IEEE 802.11 devices, such as IEEE 802.11ah devices, by allowing a station in the middle of two stations to serve as a relay station using the Wi-Fi Direct technology. Logic may enable relaying to avoid a full mesh technology such as is defined in IEEE 802.11s, since the full mesh technology may contain too many features that are not required for a simple or a static network configuration of such embodiments.

Methods and arrangements to relay packets

For example, an apparatus may be configured to cause an Access Point (AP) Multi-Link Device (MLD) to, during an ongoing communication between a first AP of the AP MLD and a first non-AP wireless communication station (STA) over a first wireless communication channel, communicate a suspend request by a second AP of the AP MLD over a second wireless communication channel, the suspend request configured to request suspension of the ongoing communication between the first AP of the AP MLD and the first non-AP STA; to suspend the ongoing communication between the first AP of the MLD and the first non-AP STA over the first wireless communication channel for a suspension period; and to communicate a frame by the first AP over the first wireless communication channel during the suspension period, the frame communicated between the first AP and a second non-AP STA.

Apparatus, system, and method of suspending a wireless communication

This disclosure describes mechanisms for performing rate matching in low-density parity check (LPDC) codes in a wireless network. A device may generate an Aggregated Media Access (MAC) Protocol Data Unit (AMPDU) payload having an AMPDU payload size associated with a number of bits. The device may omit pre-Forward Error Correction (FEC) padding of the AMPDU payload at a MAC layer by indicating the AMPDU payload size in a physical layer (PHY)-specific preamble. The device may then generate the PHY-specific preamble comprising the AMPDU payload size without the pre-FEC padding. The device may also calculate a number of Orthogonal Frequency Division Multiplexing (OFDM) symbols for containing the number of bits and transmit the PHY-specific preamble and the number of OFDM symbols to a station device.
