MOBILE DEVICE POSITION DETERMINATION USING COMPATIBLE DEDICATED-FREQUENCY NODES AND NON-DEDICATED-FREQUENCY NODES
First Claim
1. A mobile wireless communication device comprising:
- an antenna configured to send and receive signals in a dedicated frequency band that is dedicated to a communication protocol, and to receive signals in a separate frequency band that is separate from the dedicated frequency band; and
a processor, communicatively coupled to the antenna, configured to;
send, via the antenna to a location server, at least one frequency band compatibility combination wherein each of the at least one frequency band compatibility combination includes a first frequency band and a second frequency band indicative that the mobile wireless communication device can concurrently process signals in the first frequency band while processing signals in the second frequency band, the first frequency band being in the separate frequency band and the second frequency band being in the dedicated frequency band;
receive, via the antenna, a neighbor list indicating a first frequency that is in the first frequency band and indicating a second frequency that is in the second frequency band;
listen, based on the neighbor list, for a first signal that has the first frequency and that conforms to the communication protocol and for a second signal that has the second frequency and that conforms to the communication protocol; and
determine ranging information based on the first signal, the ranging information being indicative of a range from the mobile wireless communication device to a first base station that is a source of the first signal.

Abstract
A mobile device can send and receive signals in a dedicated frequency band and receive signals in a separate frequency band separate from the dedicated frequency band. The mobile device can send one or more frequency band compatibility combinations each including first and second frequency bands, the first frequency band being in the separate frequency band and the second frequency band being in the dedicated frequency. The mobile device can listen, based on a received neighbor list, for a first signal that has a frequency in the first frequency band and for a second signal that has a frequency in the second frequency band. The mobile device can determine, based on the first signal, ranging information indicative of a range from the mobile device to a source of the first signal, e.g., to obtain improved accuracy ranging information.
