Abstract
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.
Claims30
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.
2 more elements
A method of wireless communication, comprising:
- communicating, by a user device, with at least one network device at a low frequency;
- and
- receiving, at the user device, a high frequency communication directed to the user device from the at least one network device based on coarse channel properties associated with the communicating at the low frequency,
- wherein the coarse channel properties associated with the communicating at the low frequency are utilized to steer a beam that conveys the high frequency communication toward the user device, wherein the high frequency communication is maintained based on the coarse channel properties associated with the communicating at the low frequency that are continually obtained from the communicating at the low frequency to tune the high frequency communication in response to environmental changes.
