Abstract
Embodiments of the present invention provide a method, apparatus, and non-transient computer readable medium that pertain to communicating in a wireless network with a MAC layer that uses multi-level beacons, the multi-level beacons including a Discovery beacon (DB) which is transmitted in an omni mode and an announcement beacon/frame (AB) transmitted in a beam formed mode.
Claims19
A method, comprising:
- communicating in a wireless network with a MAC layer that uses multi-level beacons, said multi-level beacons including a Discovery beacon (DB) communicated during a beacon time which is transmitted in an omni mode and which is immediately followed by a beamforming training time, the beamforming training time being followed by an announcement beacon/frame (AB) transmitted in a beamformed mode;
- wherein said AB is a unicast frame addressed to a particular STA;
- and
- wherein said DB is transmitted by a piconet coordinator (PNC) that allows new STAs to discover and potentially join said piconet, in addition to serving currently associated STAs.

A machine-accessible non-transient medium that provides instructions, which when accessed, cause a machine to perform operations comprising:
- communicating in a wireless network with a MAC layer that uses multi-level beacons, said multi-level beacons including a Discovery beacon (DB) communicated during a beacon time which is transmitted in an omni mode and which is immediately followed by a beamforming training time, the beamforming training time being followed by an announcement beacon (AB) transmitted in a beamformed mode;
- wherein said AB is a unicast frame addressed to a particular STA;
- and
- wherein said DB is transmitted by a piconet coordinator (PNC) that allows new STAs to discover and potentially join said piconet, in addition to serving currently associated STAs.

An apparatus, comprising:
- a transceiver adapted to communicate in a wireless network with a MAC layer that uses multi-level beacons, said multi-level beacons including a Discovery beacon (DB) communicated during a beacon time which is transmitted in an omni mode and which is immediately followed by a beamforming training time, the beamforming training time being followed by an announcement beacon (AB) transmitted in a beamformed mode;
- wherein said AB is a unicast frame addressed to a particular STA;
- and
- wherein said DB is transmitted by a piconet coordinator (PNC) that allows new STAs to discover and potentially join said piconet, in addition to serving currently associated STAs.
