Abstract

High frequency wireless communication networks rely on directional transmit and receive beams to achieve large gains and overcome large pathlosses associated with high frequency signals. With highly directional signals, link failure may occur. Network nodes associated with the link failure, may need to identify new beam pairs and establish a new link as quickly as possible. In several aspects, beam sweep procedures are expedited, allowing for rapid link reestablishment. Disclosed techniques allow for rapid link reestablishment with and without beam correspondence.
