US 2026/0075464 A1 · METHODS, ARCHITECTURES, APPARATUSES AND SYSTEMS DIRECTED TO PHYSICAL LAYER SIGNALING IN A WIRELESS LOCAL AREA NETWORK ("WLAN") SYSTEM

Abstract

Procedures, methods, architectures, apparatuses, systems, devices, and computer program products directed physical layer signaling in a wireless local area network system are provided. Among the methods is a method that may include any of generating an extremely high throughput (EHT) physical (PHY) layer protocol data unit (PDU) (PPDU) based on a PPDU format defining a preamble comprising (i) a fixed duration universal signaling (U-SIG) field, (ii) an EHT signaling (EHT-SIG) field, and (iii) an EHT short training field (EHT-STF), wherein the U-SIG and EHT-SIG fields respectively comprise an extra signaling indicator and extra signaling to support a third feature; and transmitting the U-SIG and EHT-SIG fields on a first bandwidth segment, followed by the EHT-STF on any of the first bandwidth segment and a second bandwidth segment, followed by (iii) an EHT data field on any of the first and second bandwidth segments.

Dependent claims

A method performed by an access point (AP), the method comprising:

generating a physical-layer (PHY) protocol data unit (PPDU) for multi-AP coordinated (MAPC) operations in which the AP is a coordinating AP in communication with at least one coordinated AP,
wherein the generated PPDU at least in part includes a preamble, comprising:
at least one signaling (SIG) field, wherein the at least one SIG field comprises information indicating:
(i) a transmission opportunity (TXOP) duration, (ii) a downlink/uplink (DL/UL) direction indication, (iii) bandwidth information, (iv) a punctured-channel pattern, (v) a first basic service set (BSS) color identifying a BSS of the coordinating AP, (vi) a second BSS color identifying a BSS of the at least one coordinated AP, (vii) station identifiers (STA IDs), (viii) a resource unit (RU) allocation identifying one or more RUs, and (ix) a capability indication supported by the AP for MAPC transmissions, the capability indication comprising at least one of coordinated beamforming (Co-BF) and coordinated spatial reuse (Co-SR);
and
transmitting the PPDU.
