A load distribution method and apparatus of a base station are disclosed. The method includes measuring load information associated with the BS; transmitting the measured load information to at least one adjacent BS; receiving load information from the at least one adjacent BS; generating a first cluster including the BS and the at least one adjacent BS; and executing a load distribution operation with respect to the first cluster, wherein at least one BS included in the first cluster is included in a second cluster.

The present 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). A method and apparatus for channel estimation and equalization in a cellular environment based on quadrature amplitude modulation-filter bank multicarrier (QAM-FBMC) transmission is provided. The signal transmission method for a transmitter includes sending channel measurement information to a receiver, receiving channel related information from the receiver, selecting a first filter and a second filter to be used for signal transmission according to the received channel related information, mapping, when no performance difference is present between the first filter and the second filter, reference symbols evenly to subcarriers associated with the first filter and subcarriers associated with the second filter, mapping, when a performance difference is present between the first filter and the second filter, reference symbols preferentially to subcarriers associated with the transmitting filter with higher performance, and sending a transmit signal having the mapped reference symbols.

Method and apparatus for channel estimation and equalization in QAM-FBMC system

A method for acquiring by a base station (BS) synchronization between BSs in a mobile communication system with a distributed cell structure is provided. The method includes measuring a timing error with other BS as a synchronization target. The method also includes performing a synchronization operation with the other BS using at least one first sub-frame based on the measured timing error, wherein a number of symbols included in a first sub-frame is less than a number of symbols included in a second sub-frame.
