Abstract
Systems and methods for wireless discovery and connectivity in 802.11 networks. A management frame from an access point (AP) or personal basic service set (PBSS) control point (PCP) indicates which designated channels are operating and which are non-operating, for purposes of subsequent wireless communications, such as Association Beamforming Training (A-BFT). The management frame contains a bitmap or other forms for indicating which of the designated channels are operating and which are non-operating. In response to the information received through the management frame, one or more stations (STA) can select any one of the operating channels for transmitting of frames in A-BFT communication or other access periods in the Beacon Interval.

A method implemented by an access point (AP) or personal basic service set (PBSS) control point (PCP), the method comprising:
- generating a Directional Multi-Gigabit (DMG) beacon frame that indicates, for a plurality of designated channels, which of the designated channels are operating and which are non-operating for a station (STA) to communicate during a Beacon Interval (BI), the DMG beacon frame having bit positions that each represent a respective designated channel, and a respective bit value of each bit position indicates the operating or the non-operating of the respective designated channel,
- wherein the indicated designated channels that are operating are indicated for transmitting of, over the indicated designated channels, one or more further management frames to the station (STA) within a Beacon Header Interval (BHI) of the Beacon Interval (BI) and data within a data transmission interval (DTI) of the Beacon Interval (BI) and receiving of, over the indicated designated channels, one or more further management frames from the station (STA) within the Beacon Header Interval (BHI) and data within the data transmission interval (DTI), and
- transmitting the DMG beacon frame within the Beacon Header Interval (BHI).
A method implemented by an access point (AP) or personal basic service set (PBSS) control point (PCP), the method comprising:
- generating a Directional Multi-Gigabit (DMG) beacon frame comprising a frame that indicates, for a plurality of designated channels, which of the designated channels are operating and which are non-operating for a station (STA) to communicate during a Beacon Interval (BI), said frame having one octet of bits,
- wherein the indicated designated channels that are operating are indicated for transmitting of, over the indicated designated channels, one or more further management frames to the station (STA) within a Beacon Header Interval (BHI) of the Beacon Interval (BI) and data within a data transmission interval (DTI) of the Beacon Interval (BI) and receiving of, over the indicated designated channels, one or more further management frames from the station (STA) within the Beacon Header Interval (BHI) and data within the data transmission interval (DTI), and
- transmitting the DMG beacon frame within the Beacon Header Interval (BHI).
An access point (AP) or personal basic service set (PBSS) control point (PCP), comprising:
- a memory;
- at least one transceiver configured to communicate over a plurality of channels;
- and
- at least one processor configured to execute instructions stored in the memory to transmit within a Beacon Header Interval (BHI) of a Beacon Interval (BI) a Directional Multi-Gigabit (DMG) beacon frame that indicates, for a plurality of designated channels, which of the designated channels are operating and which are non-operating for a station (STA) to communicate during the Beacon Interval (BI), wherein the indicated channels that are operating are indicated for transmitting of, over the indicated designated channels, one or more further management frames to the station (STA) within the Beacon Header Interval (BHI) and data within a data transmission interval (DTI) of the Beacon Interval (BI) and receiving of, over the indicated designated channels, one or more further management frames from the station (STA) within the Beacon Header Interval (BHI) and data within the data transmission interval (DTI), said DMG beacon frame having bit positions that each represent a respective designated channel, and a respective bit value of each bit position indicates the operating or the non-operating of the respective designated channel.
