<p><P>PROBLEM TO BE SOLVED: To provide a ranging method and the like through a relay station capable of easily specifying network topology where the relay station RS intervenes, in a high speed wireless access system applied with IEEE802.16. <P>SOLUTION: The seed information is for generating codes of initial ranging, periodic ranging, bandwidth request, and handover ranging, in OFDMA method of IEEE802.16. It is classified in advance into a basic domain which is assigned to a mobile station present in a base station area and a relay domain assigned to a relay station present in the base station area and a mobile station present in the relay station area. The relay domain is classified in advance into a domain which is assigned to a mobile station present in the first relay station area and that assigned to the second relay station, for each seed information assigned to the first relay station. The seed information is UL_PermBase which is a part of bit information inputted in a pseudo random bit string generator. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
