1. A method of a user equipment (UE) for performing a UE based handover, the method comprising:
receiving, by the UE, a radio resource control (RRC) message including a UE based handover configuration and a configuration for a target cell, from a source base station that generates the UE based handover configuration, the RRC message also including a reporting condition or event used for handover execution indicating a duration after which reporting is to be performed;
determining whether or not to perform the UE based handover based on the UE based handover configuration received from the source base station; and
performing, based on the determination, the UE based handover towards the target cell using the configuration for the target cell when the reporting condition or event used for handover execution is satisfied but the duration has not passed,
wherein the UE, in response to a determination that the UE based handover is not yet to be performed, prohibits or suppresses triggering a measurement reporting relative to reference signal received quality (RSRQ), prohibits or suppresses initiating the RSRQ measurement reporting, and prohibits or suppresses transferring the RSRQ measurement reporting,
wherein the UE, in response to the determination that the UE based handover is not yet to be performed, prohibits or suppresses triggering a measurement reporting relative to reference signal received power (RSRP), prohibits or suppresses initiating the RSRP measurement reporting, and prohibits or suppresses transferring the RSRP measurement reporting, and
wherein the UE, in response to the determination that the UE based handover is not yet to be performed, prohibits or suppresses triggering a measurement reporting relative to reference signal signal-to-interference plus noise ratio (RS-SINR), prohibits or suppresses initiating the RS-SINR measurement reporting, and prohibits or suppresses transferring the RS-SINR measurement reporting.
