CN-122029766-A - Flexible control frames

Abstract

The present disclosure provides methods, components, devices, and systems for flexible control of frames. Some aspects relate more particularly to indicating control information or control feedback in a control frame including a flexible size field. In some implementations, a wireless device may include control feedback in a dedicated feedback field within a response control frame, an initial control frame, or both. The wireless device may use a bit sequence in one or more other subfields, such as a Traffic Identifier (TID) subfield or a user information subfield, to indicate that the field includes control feedback. In some implementations, the control feedback information may provide additional information associated with the transmission, such as information associated with the receipt status of the upcoming data transmission or communicated data transmission, to another wireless device.

Technical Field The present disclosure relates to wireless communications, and more particularly to communicating control information and control feedback using flexible control frames. Background A Wireless Local Area Network (WLAN) may be formed of one or more wireless Access Points (APs) that provide a shared wireless communication medium for use by a plurality of client devices, also referred to as wireless Stations (STAs). The basic building block of WLANs conforming to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards is the Basic Service Set (BSS) managed by an AP. Each BSS is identified by a Basic Service Set Identifier (BSSID) advertised by the AP. The AP periodically broadcasts beacon frames to enable any STA within wireless range of the AP to establish or maintain a communication link with the WLAN. In some WLANs, wireless devices may exchange control frames to facilitate data communications. For example, control frames may be exchanged to schedule one or more data frames, may indicate a receipt status of one or more data frames, or a combination thereof.
