Abstract: A method is provided. The method includes receiving, by a User Equipment (UE), a plurality of transmit (Tx) beams from a Base Station (BS), on a plurality of receive (Rx) beams. The method includes determining the beam parameters associated with a plurality of Tx and Rx beam pairs changing at a frequency above a first threshold. The method includes deriving a beam selection metric for the plurality of Tx and Rx beam pairs using the associated beam parameters. The method includes identifying a subset of Tx and Rx beam pairs from the plurality of Tx and Rx beam pairs with the beam selection metric above a second threshold. The method includes prioritizing scanning of the identified subset of Tx and Rx beam pairs to select a Tx and Rx beam pair for communication.

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 and system are provided for sensor-based beam management by user equipment (UE). The method includes obtaining, by the UE, a reference beam pair and a first set of neighbor beam pairs in a first reception direction for connecting with a network; determining, by the UE, a change in the first reception direction, based on sensor data; identifying, by the UE, a second set of neighbor beam pairs in the changed first reception direction; measuring, by the UE, a plurality of beam parameters for neighbor beam pairs in the second set of neighbor beam pairs; determining, by the UE, an optimal beam pair from the identified second set of neighbor beam pairs based on the plurality of measured beam parameters; and configuring, by the UE, an optimal beam pair for connecting with the network.

Abstract: Methods and systems for reporting CSI and selecting optimal beams using ML. The CSI report is sent to a gNB, which includes feedback parameters, computed and predicted using ML. The feedback parameters are computed using measurements performed using CSI-RS. Values of the feedback parameters likely at future, based on channel variation and the measurements, are pre-dieted using ML. The computed and predicted feedback parameters are included in the CSI report. Optimal CSI-RS resource allocation and optimal CSI reporting periodicity are determined using ML and sent to the gNB. The CSI report is encoded using the ML based model. The RSRP of the beams are predicted using ML for beam selection.
