Abstract: An operating method of a wireless communication device configured to perform wireless communication with a cell. The method involves identifying, from a downlink signal received from the cell, an electromagnetic field state associated with an antenna of the wireless communication device. A power compensation mode for compensating transmission power of a sounding reference signal is selected based on the identified electromagnetic field state. The transmission power of the sounding reference signal is compensated based on the selected power compensation mode. The sounding reference signal is transmitted with the compensated transmission power through the antenna to the cell.

Abstract: An apparatus and method for measuring a quality of a received signal of a user equipment (UE) are provided. The UE includes a bandwidth setting unit configured to determine a measurement bandwidth for a neighboring BS based on at least one bandwidth determined by a serving BS of the UE, and a measurement unit configured to measure a quality of a received signal based on the measurement bandwidth for the neighboring BS.
