Method and apparatus for management of high frequency communications in a low frequency wireless network

摘要

Wireless communication systems and methods are described where communication is established with a user device at a low frequency. Coarse channel information, such as pathloss, power delay profile, and multipath direction information, regarding the communication between a wireless network device and the user device at the low frequency may then be used to establish communication with the user device at a high frequency.

主权项

1. A method of wireless communication, comprising:
establishing, by at least one wireless network device, communication with a user device at a low frequency; identifying, by the at least one wireless network device, coarse channel properties related to the communication between the at least one wireless network device and the user device at the low frequency; establishing, by the at least one wireless network device, communication with the user device at a high frequency by utilizing the coarse channel properties related to communication at the low frequency to steer a beam that conveys the communication at the high frequency toward the user device; and maintaining the communication at the high frequency by continuing the communication at the low frequency to obtain the related coarse channel properties to tune the communication at the high frequency in response to environmental changes.
