Recovery from handoff error due to false detection of handoff completion signal at access terminal

摘要

Systems and methodologies are described that facilitate recovering from error due to false detection of completion signals at an access terminal. An access terminal specific request signal can be sent to a target base station to initiate handoff or semi-connected state exit. A completion signal can be transferred in response to the access terminal specific request signal. To mitigate errors stemming from false detection of the completion signal at the access terminal, forward link and reverse link confirmation signals can be transferred to confirm successful handoff or connected state re-entry completion. For example, the access terminal can determine handoff or re-entry to be successful when a forward link confirmation signal is detected prior to expiration of a timer. Moreover, the forward link and reverse link confirmation signals can each include more CRC bits as compared to a number of CRC bits included in the completion signal.

1. A method at an access terminal that facilitates mitigating error associated with false detection of completion signals in a wireless communication environment, comprising:
transmitting an access terminal specific request signal to a target base station; detecting a completion signal in response to the access terminal specific request signal, wherein the completion signal is one of a reverse link assignment block, a forward link assignment block, or an access grant; starting a timer upon detecting the completion signal; and confirming transmission of the completion signal from the target base station by determining whether a forward link confirmation signal is received from the target base station prior to an expiration of the timer.
