Abstract: A method of operating a wireless communication device for correcting an offset between a base station and the wireless communication device includes determining whether to perform offset correction using a first target synchronization signal block (SSB) to generate a determination result in response to changing a selected reception beam from a first reception beam to a second reception beam in an SSB period, the first target SSB being received via the second reception beam, and performing the offset correction on the second reception beam using at least one first neighbor SSB based on the determination result, the at least one first neighbor SSB being received via the first reception beam.

Abstract: An apparatus and method are provided for controlling a transmission power of a wireless communications device to comply with an output energy limit during a measurement period, including calculating a target output energy based on a communications channel; calculating a first average output energy corresponding to a previous period having a duration substantially equal to the measurement period; calculating a second average output energy by low-pass-filtering the target output energy and the first average output energy; and limiting the transmission power of the wireless communications device based on an energy margin between the output energy limit and the second average output energy.
