摘要： Methods, systems, and devices are described for interference mitigation between neighboring cells through the use of cell clusters and virtual logical cell clusters. Cells may be added to a cell cluster with a first cell when a level of interference coupling between the first cell and one or more neighboring cells exceeds a first threshold. One or more other cells may be added to a virtual logical cell cluster with the first cell when the level of interference coupling is between a second threshold and the first threshold, the second threshold being less than the first threshold. Interference mitigation between cells of cell clusters and/or virtual logical cell clusters may be performed. Interference mitigation may be accomplished through, for example, coordination of TDD uplink-downlink (UL-DL) configurations for cell clusters and scheduling-dependent interference management (SDIM) for virtual logical cell clusters.

摘要： A method, a computer program product, and an apparatus for separating a cell cluster to two or more cell clusters are provided. The cell cluster may be separated into two or more cell clusters in order to mitigate interference between cells while allowing for TDD subframe configuration flexibility. The method identifies at least one separating cell in a cell cluster, the cell cluster including at least two cells having a common TDD subframe configuration, where a coupling loss between one cell in the cell cluster and at least another cell in the cell cluster is lower than a predefined threshold. The method separates the cell cluster based on the at least one separating cell into at least a first cell cluster and a second cell cluster and sets a first TDD subframe configuration for the first cell cluster and a second TDD subframe configuration for the second cell cluster.

摘要： A method of interference suppression in a wireless cellular network includes notifying a first base station that there is a second User Equipment (UE) that currently suffers downlink interferences from the first base station, when an second UE in an active state suffers the downlink interferences from the first base station; and reallocating, by the first base station, spectrum resources for a first UE communicating with the first base station. A first base station, a second UE and a second base station for implementing the above method of interference suppression are also provided. When the second UE in the active state suffers the downlink interferences from an adjacent first base station, the first base station can adjust the spectrum resources occupied by the first UE through resource scheduling, so as to reduce the downlink interferences on the second UE in the active state, thus to reduce the influence on the communication between the second UE and the second base station.

摘要： Switched-beam antenna arrangement means use a method of controlling an antenna pattern of such antenna arrangement means. Each antenna pattern of a predetermined number of fixed antenna patterns is allocated to a predetermined time slot of a time multiplexed signal. The switched-beam antenna arrangement means is switched to generate the fixed antenna patterns during their allocated time slots. Thereby, any user can choose between distinct beam patterns by selecting an appropriate time slot, so that the risk that the user is located at the intersection area of two beams is greatly reduced.

摘要： Methods, systems, and-devices are described for interference mitigation in a time-division duplex(TDD)wireless communication system. First and second subframe types may be identified for TDD subframes to be transmitted using the system. Different power control parameters associated with each subframe type may be identified based on transmission directions in neighboring cells for the particular subframes. One or more TDD subframes to be transmitted may be identified as a first or second subframe type, and power control may be applied to the transmitted subframes according the power control parameter associated with the subframe type. The identification of subframes and power control parameters to be applied to each type of subframe may be transmitted, for example, to a user equipment(UE). The information may be transmitted to a UE, for example, via radio resource control(RRC)signaling or via a physical layer control channel.
