Method and apparatus for broadcasting position location data in a wireless communication system

In a wireless communication system, a method for broadcasting position location data (PLD) from a base station to a plurality of terminals, comprising:

• selecting one or more PLD elements for broadcast to the plurality of terminals, wherein each PLD element corresponds to a unit of PLD information of a particular type and for a particular transmitter;
• defining a schedule for broadcasting the one or more selected PLD elements, wherein the schedule is valid for a particular scheduled time interval reater than 500 seconds;
• forming a scheduling table representative of the defined schedule;
• and
• broadcasting the scheduling table and the one or more selected PLD elements to the plurality of terminals.

A base station in a wireless communication system, comprising:

• a controller operative to
• select one or more PLD elements for broadcast, wherein each PLD element corresponds to a unit of PLD information of a particular type and for a particular transmitter,
• define a schedule for broadcasting the one or more selected PLD elements, and
• forming a scheduling table representative of the defined schedule;
• and
• a transmit data processor coupled to the controller and operative to process the scheduling table and the one or more selected PLD elements for broadcast to the plurality of terminals;
• wherein the schedule is indicative of the one or more selected PLD elements, their broadcast order, and specific time intervals for their broadcast, and wherein the schedule is valid for a particular scheduled time interval and the scheduling table is broadcast a plurality of times during the scheduled time interval.
