Abstract
A mobile station determines, in accordance with reception quality of a radio signal from a base station, a measurement cycle of a predetermined measurement on a link status and/or on/off of the predetermined measurement and controls execution of the predetermined measurement based on the determination.
Claims19
A base station, comprising:
- a transmitter configured to transmit to a mobile station a signal for performing a measurement of a first cell quality value of a first cell;
- and
- a receiver configured to receive a result signal including a result of the measurement and a position information from the mobile station, wherein
- the mobile station performs the measurement and associates the position information with the result in response to a second cell quality of a second cell being equal to or less than a threshold,
- wherein the second cell quality of the second cell is measured by the mobile station.

A communication method, comprising:
- by a base station, transmitting to a mobile station a signal for performing a measurement of a first cell quality of a first cell;
- and
- receiving a result signal including a result of the measurement and a position information from the mobile station, wherein
- the mobile station performs the measurement and associates the position information with the result in response to a second cell quality of a second cell being equal to or less than a threshold,
- wherein the second cell quality of the second cell is measured by the mobile station.
2 more elements
A base station, comprising:
- a receiver configured to receive a result signal including a result of a measurement of a first cell quality value based on a signal transmitted from a first cell and a position information available in a mobile station from the mobile station;
- wherein
- the mobile station comprising:
- a first unit to compare a measured second cell quality value based on a signal transmitted from a second cell with a threshold, and to determine whether to perform the measurement of the first cell quality value based on the signal to be transmitted from the first cell, based on a result of the comparison;
- a second unit to perform the measurement of the first cell quality value and to associate the position information with the result of the measurement of the first cell quality value, in response to the measured second cell quality value being equal to or less than the threshold;
- and
- a third unit to report the result of the measurement of the first cell quality value and the position information to the base station.

4 more elements
A base station, comprising:
- a transmitter configured to transmit to a mobile station a signal for performing a measurement of a first cell quality value of a first cell;
- and
- a receiver configured to receive a result signal including a result of the measurement and a position information from the mobile station only when a second cell quality of a second cell is equal to or less than a threshold,
- wherein the second cell quality of the second cell is measured by the mobile station.
