Forced Beam Switching in Wireless Communication Systems having Smart Antennas
First Claim
Patent Images
1. A method for use in a wireless communication system, the method comprising:
- selectively allowing a receiving device to operatively associate with a beam downlink transmittable to the receiving device via a phased array antenna of an access point;
receiving an uplink transmission from the receiving device through the phased array antenna;
determining from the uplink transmission if the receiving device should operatively associate with a different beam downlink transmittable via the phased array antenna; and
allowing the receiving device to operatively associate with the different beam downlink if determining that the receiving device should operatively associate with the different beam downlink.

12. A method as recited in claim S, further comprising:
-
transmitting probe messages to the receiving device separately over the beam downlink and the different beam downlink;
receiving corresponding uplink transmitted probe response messages from the receiving device through the phased array antenna; and
gathering signal parameter information from each of the uplink transmitted probe response messages. - View Dependent Claims (13)

18. A wireless communication system, comprising:
-
a phased array antenna configured to transmit beam downlinks;
a transceiver operatively coupled to the phased array antenna and configured to send and receive electromagnetic signals via the phased array antenna; and
an access point that includes the phased array antenna and the transceiver, the access point configured to;
selectively allow a receiving device to operatively associate with a beam downlink transmitted to the receiving device via the phased array antenna;
receive an uplink transmission from the receiving device through the phased array antenna;
determine from the uplink transmission if the receiving device should operatively associate with a different beam downlink transmission; and
at least one of;
allow the receiving device to operatively associate with the different beam downlink if determined that the receiving device should operatively associate with the different beam downlink;
force the receiving device to operatively associate with the different beam downlink if determined that the receiving device should be operatively associated with the different beam downlink. - View Dependent Claims (19, 20)
