A method and apparatus for an interference-aware resource-sharing scheme for multiple D2D group communications is provided. The method for interference-aware resource-sharing scheme for multiple D2D communications includes initializing a D2D communication request and deciding the numbers of D2D pairs and CUEs, grouping D2D pairs according to the decided numbers of the D2D pairs and CUEs, selecting target CUEs for the grouped D2D pairs to share frequency resources, applying interference alignment to the D2D groups, updating the set of the CUEs and D2D pairs, and moving the rest of the D2D pairs to the orthogonal group.

A power control system and method to mitigate interference in a heterogeneous network is provided. A power control method to mitigate interference may include: receiving a link connection request from a femto terminal; transmitting a downlink signal when the link connection request is allowed; receiving information of a macro terminal present around a femto base station; controlling a power of the downlink signal in response to a high interference indicator (HII) report being included in the received information of the macro terminal; and controlling the power of the downlink signal based on a priority of service while satisfying predetermined constraints, in response to the HII report in a state in which the power of the downlink signal is decreased up to a predetermined required power.

System and method to mitigate interference of 3GPP LTE heterogeneous network according to priority of service

A method and system to dynamically allocate a frequency based on a priority of quality of experience (QoE) is disclosed. A method to dynamically allocate a frequency may include: securing a predetermined frequency band and a bonus frequency band for a macrocell; allocating the predetermined frequency band and the bonus frequency band to a macro terminal located in the macrocell; allocating the bonus frequency band based on the priority of service in a subsequent time slot when a frequency band comprising the predetermined frequency band and the bonus frequency band is not allocated to the macro terminal.
