Scanning neighboring base stations in wireless access system

A mobile station for scanning neighboring base stations for measuring channel quality in a wireless communication system, the mobile station comprising:

• a receiver;
• and
• a transmitter,
• wherein the mobile station is configured to:
• receive, via the receiver from a serving base station, information associated with at least one neighboring base station;
• transmit, via the transmitter to the serving base station, a scanning request message to request an allocation of a scanning interval for scanning;
• and
• receive, via the receiver from the serving base station, a scanning response message comprising an allowed scan duration in response to the scanning request message,
• wherein the scanning request message comprises parameters associated with a requested scan duration, a requested interleaving interval interleaved between each scan, and a requested scan iteration, and
• wherein the allowed scan duration is set to zero to indicate that the request for the allocation of the scanning interval is denied.

A method for supporting scanning of neighboring base stations at a mobile station in a wireless communication system, the method comprising:

• transmitting, by a serving base station to the mobile station, information associated with at least one neighboring base station;
• receiving, by the serving base station from the mobile station, a scanning request message to request an allocation of a scanning interval for scanning, the scanning request message comprising a requested scan duration, a requested interleaving interval, and a requested scan iteration, wherein the requested interleaving interval is interleaved between each scan;
• and
• transmitting, by the serving base station to the mobile station, a scanning response message comprising an allowed scan duration in response to the scanning request message,
• wherein the allowed scan duration is set to zero to indicate that the request for the allocation of the scanning interval is denied.

A serving base station supporting scanning of neighboring base stations at a mobile station in a wireless communication system, the serving base station comprising:

• a transmitter;
• and
• a receiver,
• wherein the serving base station is configured to:
• transmit, via the transmitter to the mobile station, information associated with at least one neighboring base station;
• receive, via the receiver from the mobile station, a scanning request message requesting an allocation of a scanning interval for scanning;
• and
• transmit, via the transmitter to the mobile station, a scanning response message comprising an allowed scan duration in response to the scanning request message,
• wherein the scanning request message comprises a requested scan duration, a requested interleaving interval interleaved between each scan, and a requested scan iteration, and
• wherein the allowed scan duration is set to zero to indicate that the request for the allocation of the scanning interval is denied.
