Quick paging in telecommunication systems

摘要

In an orthogonal frequency division multiple access communication system, unused frequency resources during a conventional preamble signal are used for a quick paging mechanism. A set of quick paging signals is sent over the unused frequency resources to signal one or more subscriber stations.

1. A method of quick paging in a communication system using a plurality of subcarriers for orthogonal frequency division multiple access, wherein a preamble signal comprises one or more preamble sequences, at least one predetermined preamble sequence being successively transmitted on a predetermined first set of the subcarriers, the method comprising:
receiving, at a base station, a request to page one or more subscriber stations believed to be in a paging area that includes the base station; identifying, by the base station, at least one quick paging code word that corresponds to the one or more subscriber stations; transmitting the at least one quick paging code word on a second set of subcarriers; wherein the second set includes only subcarriers that were not previously used in the preamble signal, and the quick paging code word and the at least one predetermined preamble sequence are transmitted simultaneously in the preamble signal.
