AI Technical Summary

Problems solved by technology

However, due to the deeper fading and strict directivity requirements of the 60GHz band, links at 60GHz can lose connectivity quickly
As a result, applications such as streaming video and data file transfers may experience long delays and a poor user experience when the connection needs to be re-established

Abstract

A method for wireless communications is provided that includes generating an index for a plurality of packets for use in a first radio link for transmission to an apparatus; transmitting the plurality of packets using a second radio link to the apparatus; determining transmission state information indicating whether each packet in the plurality of packets have been received by the apparatus; and transmitting additional packets based on the index and the transmission state information. Apparatuses for performing the methods are also disclosed.
