Abstract:
A disclosed paging method includes a random access channel generating step of, when a group including an own station is being paged based on a paging indicator channel (PICH) transmitted from a base station apparatus, generating a random access channel (RACH) including information indicating a response to the paging indicator channel (PICH) by a mobile station apparatus; a transmitting step of transmitting the random access channel (RACH) by the mobile station apparatus; a random access channel detecting step of detecting the random access channel (RACH) as the response to the paging indicator channel (PICH) by the base station apparatus; a paging information generation determining step of determining whether paging information is to be generated based on a detection result of the random access channel (RACH); and a paging information generating step of generating paging information based on the determination result.
