US 2026/0247352 A1 · ENHANCED TRIGGER FRAME

Abstract

This disclosure provides methods, devices and systems for generating enhanced trigger frames. Some implementations more specifically relate to trigger frame designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an enhanced trigger frame may be used to solicit a non-legacy trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) from one or more wireless stations (STAs). In some implementations, the enhanced trigger frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, an enhanced trigger frame may be configured in accordance with a legacy trigger frame format or a non-legacy trigger frame format. Thus, when configured in accordance with the legacy trigger frame format, the enhanced trigger frame can also be used to a legacy TB PPDU from one or more STAs.

Claims1

Dependent claims

A wireless station, comprising:

at least one modem;
at least one processor communicatively coupled with the at least one modem;
and
at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor in conjunction with the at least one modem, is configured to:
receive a trigger frame soliciting a physical layer protocol data unit (PPDU), the trigger frame including a medium access control (MAC) header, a common information field, and a user information list that includes a special user information field and one or more user information fields, wherein the special user information field includes an association identifier (AID) value not assigned to any wireless stations and an uplink bandwidth extension subfield indicating bandwidth information associated with the PPDU;
and
transmit the PPDU based at least in part on the bandwidth information.
