Claim Text:
1. A method of communicating beacon messages in a base station subsystem comprising an access point and an access terminal, the method comprising: transmitting, from the access point to the access terminal, a repeating finite sequence of beacon messages, the sequence comprising a first beacon message comprising a relative position identifier to indicate timing of subsequent beacon messages in the finite sequence and to identify content included in the subsequent beacon messages, wherein the subsequent beacon messages include information not included in the first beacon message; transmitting, from the access point to the access terminal, a time offset, an absolute time, and a sequence number to enable the access terminal to transition from a low power state to a high power state at a time determined from the time offset, the absolute time, and the sequence number; and decoding, at the access terminal, the first beacon message and a proper subset of the sequence of beacon messages based upon the relative position identifier, wherein the access terminal is in a low power state during transmission of a second subset of sequence of beacon messages, and the second subset of beacon messages comprises beacon messages not in the proper subset and does not include the first beacon message.
