Abstract:
1. A user equipment terminal for measuring signal power in a neighbor cell, comprising: a movement speed estimating unit configured to estimate a movement speed of the user equipment terminal or a fading frequency of a propagation; a measurement bandwidth determining unit configured to determine a number of resource blocks for measuring signal power of the neighbor cell among a plurality of resource blocks included in a system bandwidth according to the movement speed or the fading frequency of the propagation; and a measurement unit configured to measure signal power of the neighbor cell within a measurement bandwidth corresponding to the determined number of resource blocks, wherein, the movement speed estimating unit estimates that the movement speed is slower than a second threshold or that the fading frequency is lower than a third threshold, when a time interval during which time correlation of a downlink reference signal is shown is longer than a first threshold, and estimates that the movement speed is faster than the second threshold or that the fading frequency is higher than the third threshold, when the time interval during which time correlation of the downlink reference signal is shown is shorter than the first threshold, and the measurement bandwidth determining unit decreases the number of resource blocks when the movement speed is faster than the second threshold or when the fading frequency is higher than the third threshold and increases the number of resource blocks when the movement speed is slower than the second threshold or when the fading frequency is lower than the third threshold.
