Patent ID: 11510156

Abstract:
The disclosure relates to 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). The disclosure provides a method for sending a power headroom report (PHR) to a base station in a multi-rat dual connectivity (MR-DC) deployment in a UE (100). The method comprises determining, by the UE (100), that a transmit power required is greater than a maximum transmit power of the UE (100) and determining, by the UE (100), a PHR reporting criteria is met. The method also includes performing, by the UE (100) at least one of: modifying the power headroom such that the transmit power is less than or equal to the maximum transit power of the UE (100); modifying the maximum transmit power such that the power headroom report indicates that the transmit power required is less than or equal to the maximum transmit power and triggering the power headroom report to the base station; and delaying the triggering and reporting of PHR to the base station.
