Abstract: Methods and systems for tracking frequency offset in NR are provided. A user equipment (UE) can compute the frequency offset comprising of crystal frequency drift and Doppler shift. Drift in frequencies generated by crystal oscillators in the UE and a base station are detected and nullified. Doppler shift of a serving beam is estimated using either data collected by sensors in the UE or reference signals received from the base station. Values of Doppler shift for a plurality of beams are estimated using the Doppler shift of the serving beam and sensor data, wherein the serving beam and the plurality of beams correspond to a same transmitter beam or different transmitter beams, wherein the type of QCL of the beams is either A, B, or C.

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.
