Abstract: The disclosure relates to 5G or pre-5G communication systems for supporting higher data transfer rates, following the 4G communication systems, such as LTE.
The disclosure describes a method and a UE for sensor-based optimal antenna array switching in a wireless communication system. The method comprising: detecting at least one orientation parameter of the UE using one or more sensors of the UE, comparing a current signal strength parameter value of one or more serving Antenna Array Modules (AAMs) of the UE with a first threshold value or comparing a non-serving AAM monitor timer of the UE with a second threshold value, comparing at least one orientation parameter with a third threshold value based on the current signal strength parameter value of one or more serving AAMs being less than the first threshold value or based on the non-serving AAM monitor timer exceeding the second threshold value, performing measurements on one or more non-serving AAMs, and selecting at least the one or more serving AAMs and the one or more non-serving AAMs based on the measurements performed.

Abstract: A method for managing beam alignment by a user equipment is provided. The method comprises receiving beam width information and base station location information from a base station, calculating a displacement of location of the UE based on location coordinates of the UE, measuring a change in a signal strength of the UE due to the displacement, and determining whether the UE is moving towards or away from the base station using at least one of the beam width information, base station location information, the displacement, and the measured change in the signal strength, determining whether a a beam re-alignment is required based on the determination of the movement of UE, and transmitting a realignment request to the base station for a re-aligned beam width and a new transmission beam based on determining that the beam re-alignment is required.

Abstract: A method for performing a channel state information (CSI) prediction by a user equipment (UE) is provided. The method includes receiving a plurality of reference signals from a base station, obtaining a channel quality information (CQI) estimation for an interval based on the received plurality of reference signals, wherein obtaining the CQI estimation includes obtaining at least one of mean mutual information per bit (MMIB) or effective exponential signal to noise ratio mapping (EESM), predicting the CSI based on the CQI estimation, and reporting the predicted CSI to the base station.
