DISTRIBUTION AND UTILIZATION OF ANTENNA INFORMATION FOR LOCATION DETERMINATION OPERATIONS
First Claim
1. A method comprising, at a processor-based mobile device:
- receiving at the mobile device antenna information for a wireless node, including a transmitter gain for the wireless node, in at least one message transmitted to the mobile device, the at least one message including;
a beacon frame message configured according to IEEE 802.11 standard transmitted from the wireless node, a fine timing measurement (FTM) protocol-based message, an assistance data message transmitted from a remote central repository of information, or any combination thereof;
deriving an estimate of a receiver gain for a receiver of the mobile device based, at least in part, on the transmitter gain for the wireless node; and
adjusting one or more signal strength values determined for signals received from the wireless node based on the estimate of the receiver gain of the receiver of the mobile device derived based, at least in part, on the transmitter gain for the wireless node.

Abstract
Disclosed are implementations, including a method, performed at a processor-based mobile device, that includes receiving at the mobile device antenna information for a wireless node, including a transmitter gain for the wireless node in at least one message transmitted to the mobile device. The at least one message includes, a beacon frame message, a fine timing measurement (FTM) protocol-based message, and/or an assistance data message transmitted from a remote central repository. The method also includes deriving an estimate of a receiver gain for a receiver of the mobile device based, at least in part, on the transmitter gain for the wireless node, and adjusting one or more signal strength values determined for signals received from the wireless node based on the estimate of the receiver gain of the receiver of the mobile device derived based, at least in part, on the transmitter gain for the wireless node.
