Claim 4:
5. A method of a source base station for performing a user equipment (UE) based handover, the method comprising:
generating, by the source base station, a UE based handover configuration;
configuring, by the source base station, the UE based handover configuration and a configuration for a target cell in a radio resource control (RRC) message for performing the UE based handover, the configured RRC message including handover execution condition information indicating whether or not to perform the UE based handover, the RRC message also including a timer value for indicating a validity period for the handover; and
transmitting, from the source base station to a UE, the configured RRC message,
wherein the UE, in response to a determination that the timer is running and therefore the UE based handover is still valid, but, according to the configured RRC message, not yet to be performed, even when a reporting condition or event used for handover execution is satisfied, 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 a determination that the timer is running and therefore the UE based handover is still valid, but, according to the configured RRC message, not yet to be performed, even when a reporting condition or event used for handover execution is satisfied, 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 a determination that the timer is running and therefore the UE based handover is still valid, but, according to the configured RRC message, not yet to be performed, even when a reporting condition or event used for handover execution is satisfied, 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.
