Abstract: An access point is identified based on a plurality of pilot signatures. Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature. For example, an access point may use one PN offset to generate a pilot signal and transmit a message that identifies at least one other PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot-related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal.

Abstract: Apparatus and methods are disclosed for adapting the power of an access probe transmission, in accordance with a reverse link underload indicator provided by the base station. In one example, the base station can transmit a one-bit reverse link underload indicator as an information element broadcasted within a general page message (GPM). Here, the reverse link underload indicator can indicate whether a measured rise-over-thermal (RoT) at the base station is less than a given threshold. The access terminal may accordingly reduce the initial transmit power of an access probe transmission in the case of a reverse link underload condition, as this condition would indicate that the base station could accommodate reduced power access probe transmissions without substantially decreasing the probability of a quick detection of the access attempt. Other aspects, embodiments, and features are also claimed and described.

Abstract: Access terminals and network nodes are adapted to conduct access terminal registrations. In one example, an access terminal with a respective class designation may receive a message including a plurality of periodic registration schedules, where at least one registration schedule is associated with an access terminal class. The access terminal may determine a periodic registration schedule associated with its respective class designation, and may perform periodic access terminal registrations according to the determined periodic registration schedule. In one example, a network node can obtain a plurality of periodic registration schedules, with at least one registration schedule associated with an access terminal class. The network node can transmit a message including the plurality of periodic registration schedules, and can conduct access terminal registrations according to the plurality of periodic registrations schedules. Other aspects, embodiments, and features are also claimed and described.
