    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 pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Methods and systems for adapting beamwidth of beams on NR physical channels are provided. Alignment between beams of a UE and a gNB is created by refining beam codebooks. Phase shifters and PAs/LNAs of antenna elements are tuned for refining the beam codebooks. Strength of a signal, received through different RX beams, is determined based on RSRP/SINR associated with the different RX beams. A direction is determined, along which RSRPs/SINRs associated with consecutive RX beams is increasing. A pair of RX beams is determined, the RSRP/SINR associated with a first beam being greater than e RSRP/SINR associated with a second beam, and the RSRP/SINR associated with the first beam is the greatest along the determined direction.

    Abstract: Embodiments herein provide methods and systems for achieving D2D communications through unlicensed spectrum. The D2D-U operations can be achieved through multiple approaches. In the first approach, the devices can communicate with each other without any involvement of network. In the second approach, the network provides partial assistance to the devices such as allocating time and frequency resources for D2D-U communication. In the third approach, the network completely controls D2D-U operations between the devices. The embodiments include allocating time and frequency resources for transmission of PSBCH, PSDCH, PSCCH, and PSSCH. The allocations of the time and frequency resources meet regulatory requirements of minimum bandwidth utilization for unlicensed band operation. The embodiments include distributing power in narrow frequency sub-bands of D2D-U spectrum, in order to maximize transmission range of D2D-U communications.
