Transmission of location information by a transmitter as an aid to location services

A method for wireless communication, comprising:

• generating at a base station a unicast message comprising coordinate information and uncertainty information associated with the base station wherein the uncertainty information comprises uncertainty of a horizontal location of the base station;
• and
• sending the unicast message from the base station to a specific terminal, wherein the unicast message is sent prior to establishing a positioning session with the specific terminal via a positioning protocol.

An apparatus for wireless communication, comprising:

• at least one processor configured to generate at a transmitter an overhead message comprising coordinate information and uncertainty information associated with the transmitter wherein the uncertainty information comprises uncertainty of a horizontal location of the transmitter, and to broadcast the overhead message from the transmitter to terminals within coverage of the transmitter, wherein the overhead message is broadcast prior to establishing a positioning session with the terminals via a positioning protocol.

An apparatus for wireless communication, comprising:

• means for generating at a transmitter an overhead message comprising coordinate information and uncertainty information associated with the transmitter wherein the uncertainty information comprises uncertainty of a horizontal location of the transmitter;
• and
• means for broadcasting the overhead message from the transmitter to terminals within coverage of the transmitter, wherein the overhead message is broadcast prior to establishing a positioning session with the terminals via a positioning protocol.

A computer program product, comprising:

• a non-transitory computer-readable storage medium comprising:
• code for causing at least one computer to generate at a transmitter an overhead message comprising coordinate information and uncertainty information associated with the transmitter wherein the uncertainty information comprises uncertainty of a horizontal location of the transmitter, and
• code for causing the at least one computer to broadcast the overhead message from the transmitter to terminals within coverage of the transmitter, wherein the overhead message is broadcast prior to establishing a positioning session with the terminals via a positioning protocol.

A method for wireless communication, comprising:

• generating at a base station an overhead message comprising a latitude field carrying latitude of the base station, a longitude field carrying longitude of the base station, and a horizontal location uncertainty field carrying uncertainty of the horizontal location of the base station;
• and
• broadcasting the overhead message from the base station to terminals within coverage of the base station, wherein the overhead message is broadcast prior to establishing a positioning session with the terminals via a positioning protocol.

A method for wireless communication, comprising:

• receiving at a terminal an overhead message generated and sent by a transmitter to at least one receiver in a wireless network, wherein the overhead message is received prior to establishing a positioning session via a positioning protocol;
• and
• obtaining coordinate information and uncertainty information associated with the transmitter from the overhead message wherein the uncertainty information comprises uncertainty of a horizontal location of the transmitter.
