Title: Method for operating multiplexing between heterogeneous network
Inventor: LEE MI HYUN
IPC: H04B7/155
Filed: 2007-02-22
Abstract: A method for performing a multiplexing operation between heterogeneous networks is provided to prevent a signaling overhead from increasing when a time division or a frequency division multiplexing scheme is applied between an existing system and a newly evolved system. A method for performing a multiplexing operation between heterogeneous networks comprises the following several steps. An MS(Mobile Station) receives a preamble and checks a frame start time, i.e. allocation start time of a downlink subframe. The MS obtains No. OFDMA(Orthogonal Frequency Division Multiple Access) symbol information, which is resource allocation section information for the first system in the downlink subframe, and overall frame duration by decoding a DL-MAP message(404). The MS obtains No. OFDMA symbol information, which is resource allocation section information for the first system in an uplink subframe, and allocation start time of the uplink subframe by decoding a UL-MAP message(406). The MS transmits or receives signals to or from a base station by using the obtianed information(408).
