1. An apparatus, comprisinga first wireless communications device containing a processor and a radio, the first wireless communications device to:
- detect loss of a first directional communications link between the first wireless communications device and a second wireless communications device; and
transmit, omnidirectionally, a superframe containing a beacon and a time period for scheduled communications prior to receiving a request for the time period from the second wireless communication device;
wherein the beacon indicates a first portion of the time period for antenna training between the first and second wireless communications devices.

Abstract
In a wireless network using directional communication links between devices in the network, when the network controller detects that one or more of the directional links is lost, it may use a beacon to schedule separate antenna training periods for the devices involved in the lost links. In some embodiments, all of the training periods may take place in the same superframe as the beacon.
