Methods and devices for parallel page decoding from neighboring cells

摘要

Various features and aspects of the present disclosure are adapted to facilitate improved reception of page messages at an access terminal operable in a wireless communication system. When the access terminal is in a region where two or more cells overlap, if the access terminal is moving away from the coverage area of an active cell and moving towards the coverage area of a neighbor cell, the access terminal may miss an incoming page message transmitted from its serving cell. Thus, the access terminal may dedicate fingers of a rake receiver to listen to paging information transmitted from one or more neighbor cells, decoding this information if a page decoding operation corresponding to the active cell fails. Other aspects, embodiments, and features are also claimed and described.

1. A method of wireless communication operable at an access terminal in idle mode, the method comprising:
initiating a parallel page decoding process based on one or more parameters comprising at least one of an active service cell signal quality, a neighboring cell signal quality, a relative value of a neighboring cell signal quality with respect to an active service cell signal quality, channel conditions, a channel estimation, cells overheads, or a number of active pilot paths; allocating a second finger of a rake receiver in the access terminal to track a neighboring cell while a first finger of the rake receiver in the access terminal is configured to receive paging information from an active cell; utilizing the second finger, receiving paging information from the neighboring cell in parallel with the receiving of the paging information from the active cell; attempting to decode paging information, comprising a page message, received from the active cell; if the access terminal fails to decode the page message from the received paging information from the active cell, decoding a page message from the parallelly received paging information from the neighboring cell; and if the access terminal determines that the decoded page message from the neighboring cell includes an access terminal directed page, performing an idle handoff to the neighboring cell for processing a mobile terminated call.
