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.

Claims

1. A computer readable media including computer readable instructions that may be utilized by one or more processors, the instructions comprising:

instructions for determining presence of a scheduled message for the access terminal;

instructions for 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;

instructions for compressing the quick paging block to generate a compressed quick paging block;

instructions for encoding the compressed quick paging block to generate an encoded quick paging packet;

instructions for generating at least one Orthogonal Frequency Division Multiplex (OFDM) symbol having at least a portion of the encoded quick paging block; and

instructions for transmitting the at least one OFDM symbol,

wherein the instructions for compressing the quick paging block comprises;

instructions for determining a number of asserted quick paging bits from the plurality of quick paging bits; and

instructions for generating successive fields indicating positions of the asserted quick paging bits within the quick paging block if the number of asserted bits is less than a predetermined amount.

2. A computer readable media including computer readable instructions that may be utilized by one or more processors, the instructions comprising:

instructions for setting a quick paging bit corresponding to the access terminal in a quick paging block having a plurality of bits corresponding to a plurality of access terminals;

instructions for compressing the quick paging block to generate a compressed quick paging block; and

instructions for encoding the compressed quick paging block to generate an encoded quick paging block,

wherein the instructions for compressing the quick paging block comprises;

instructions for determining a number of asserted quick paging bits from the plurality of quick paging bits; and

instructions for generating successive fields indicating positions of the asserted quick paging bits within the quick paging block if the number of asserted bits is less than a predetermined amount.

3. A computer readable media including computer readable instructions that may be utilized by one or more processors, the instructions comprising:

instructions for processing a quick paging packet;

instructions for decoding the quick paging packet to generate a quick paging block;

instructions for decompressing the quick paging block; and

instructions for determining a status of a quick paging bit associated with an access terminal based on an output of the decompressing process,

wherein the instructions for decompressing the quick paging block comprises;

instructions for determining a number of asserted quick paging bits represented in the quick paging block; and

instructions for examining positions of the asserted quick paging bits in successive fields within the quick paging block to determine whether a quick paging bit associated with an access terminal is asserted.

4. The computer readable media of claim 3, the instructions further comprising:

instructions for determining a position of an asserted bit in the quick paging block based on an output of the decompressing process; and

instructions for comparing the position to a position of the quick paging bit associated with the access terminal.
