Title:
TIME REDUCTION FOR MULTIPLE LINK RECOVERY
Document Type and Number:
WIPO Patent Application WO/2011/087611
Kind Code:
A3
Abstract:
Apparatuses, systems, and methods that reduce the amount of time for recovering multiple beam-formed links in a wireless network are disclosed. An embodiment may, e.g., be a mobile computing device with wireless beamforming communications capabilities. Upon establishing links with multiple stations, the mobile computing device may sense that the link quality or strength is degrading for several of the links. The laptop may transmit a single forward-transmission sector sweep (FWD-TXSS) to initiate recovery of the links. The other stations previously linked to the laptop may detect the degradation the links and start monitoring for the single FWD-TXSS. The receiving devices may each perform reverse-transmission sector sweeps (REV-TXSS), in sequence, to reestablish beam-formed links with the laptop without requiring multiple forward-transmission sector sweeps.
