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: The embodiments herein provide methods and systems for implementing time division duplex (TDD) operations in a narrowband internet of things (NB-IoT) to enable cellular IoT operations in user equipment (UE). A method includes receiving TDD uplink-downlink (UL-DL) configuration and transmitting a predetermined number of a symbol group for a random access in one or more UL subframes based on the received TDD UL-DL configuration, each symbol group including a plurality of symbols, wherein at least part of the predetermined number of symbol groups are transmitted discontinuously.
