Quick paging channel with reduced probability of missed page
First Claim
1. A method of notifying an access terminal, the method comprising:
- determining presence of a scheduled message for the access terminal;
setting a quick paging bit from a plurality of quick paging bits in a quick paging block, the quick paging bit corresponding to the access terminal;
encoding the quick paging block to generate an encoded quick paging packet;
generating at least one Orthogonal Frequency Division Multiplex (OFDM) symbol having at least a portion of the encoded quick paging block; and
transmitting the at least one OFDM symbol.

Abstract
A quick paging channel in a random access wireless communication system includes at least one bit in a quick paging frame identifying the presence of a paging message for an access terminal or group of access terminals. The quick paging bits identifying the presence of a paging message for a first access terminal is encoded with one or more quick paging bits corresponding to one or more additional access terminals to produce one or more forward error correction bits. The jointly encoded quick paging bits are broadcast to the access terminals by time division multiplexing the quick paging frame with additional frames of information.
