Patent ID: 8116319

Claim:
A method for supporting coexistence in a mobile station configured for supporting a coexistence mode of a primary wireless communication system and a secondary wireless communication system while considering subchannel allocation, the method comprising: transmitting to a base station, at the mobile station, a sleep mode request (MOB SLP-REQ) message comprising first coexistence information, for requesting a band adaptive modulation and coding (AMC) for adjacent subcarrier permutation; receiving a sleep mode response message (MOB SLP-RSP) including second coexistence information in response to the MOB SLP-REQ message; and requesting the release of the adjacent subcarrier permutation by transmitting the MOB SLP-REQ message to the base station, wherein the MOB SLP-REQ message includes third coexistence information for requesting partial usage subchannel (PUSC) allocation to the mobile station, wherein the primary wireless communication system is a WiMAX system and the transmission of the MOB SLP-REQ message including the third coexistence information is performed in a WiMAX active period.
