Techniques to efficiently broadcast position location data (PLD) from a base station to a number of terminals. In one aspect, PLD messages are classified into groups, and each group is broadcast in a different manner. For example, a first group of messages for PLD related to the base station is broadcast in an unscheduled format, and a second group of messages for PLD related to GPS satellites is broadcast in a scheduled format. In another aspect, a schedule for the second group describes the specific PLD elements selected for broadcast, their broadcast order, and the specific time intervals of their broadcast. The schedule is valid for a particular scheduled time interval, and the scheduling table is broadcast multiple times during the scheduled time interval to allow the terminals to quickly retrieve the schedule and ascertain what PLD information is being broadcast and where to look for specific PLD elements.
