Abstract: A system and method for characterizing an interference demodulation reference signal (DMRS) in a piece of user equipment (UE), e.g., a mobile device. The UE determines whether the serving signal is transmitted in a DMRS-based transmission mode; if it is, the UE cancels the serving DMRS from the received signal; otherwise the UE cancels the serving data signal from the received signal. The remaining signal is then analyzed for the amount of power it has in each of four interference DMRS candidates, and hypothesis testing is performed to determine whether interference DMRS is present in the signal, and, if so, to determine the rank of the interference DMRS, and the port and scrambling identity of each of the interference DMRS layers.

Abstract: A wireless communication device including processing circuitry configured to generate first synchronization signal measurement values by combining sets of correlation values, the sets of correlation values being based on a reception signal, and each of the sets of correlation values having a number of correlation values equal to a first accumulation count, determine whether a valid synchronization signal measurement value is detected among the first synchronization signal measurement values based on a criterion, determine a frequency corresponding to the first valid synchronization signal measurement value as a synchronization frequency in response to determining the valid synchronization signal measurement value is detected, determine a second accumulation count in response to determining the valid synchronization signal measurement value is not detected, generate second synchronization signal measurement values based on the second accumulation count, and perform an initial access operation for synchronization with a base station using the synchronization frequency.

Abstract: A mode switching method and apparatus of a terminal including a camera for acquiring motion information of a user and a plurality of operation modes for power management is provided. The mode switching method includes transitioning, when a motion of a first pattern is detected by the camera, the terminal from an active mode to a standby mode, transitioning, when a motion of a second pattern is detected by the camera, the terminal from the standby mode to an inactive mode, and transitioning, when a first mode switching input is detected in the inactive mode, from the inactive mode to the active mode, wherein the camera acquires the motion information of the user in at least one of the active mode and the standby mode.
