Abstract
A method and device for performing wireless communication ranging are provided. A machine-to-machine (M2M) device receives a paging message from a base station, transmits a bandwidth request (BR) preamble sequence to the base station, receives a first UL grant to allocate an uplink (UL) resource for the transmission of a BR header, transmits the BR header including a ranging request indication parameter to the base station through a UL resource allocated by the first UL grant, receives a second UL grant to allocated a UL resource for transmission of a ranging request message from the bases station, and transmits the ranging request message to the base station through a UL resource allocated by the second UL grant.
