MECHANISM FOR CONTROLLING AN UPLINK COMMUNICATION DESCRIPTION

摘要

There is provided a mechanism for controlling a communication in UL direction where a load balancing mechanism such as carrier switching is conducted. When a carrier switching for switching a communication from at least one first uplink frequency carrier to at least one second uplink frequency carrier is executed, it is determined whether a retransmission of data is required. In case a time being measured beginning from a switching time where the carrier switching is executed is below a threshold, the retransmission of the data is disabled.
