20130194982 | INTERFERENCE MANAGEMENT FOR DYNAMIC UPLINK AND DOWNLINK CONFIGURATION - An apparatus and method for managing interference to facilitate allocation of a dynamic uplink and downlink configuration are disclosed herein. Determining whether a first cell causes interference less than a pre-determined threshold level to one or more neighboring cells or whether flexible subframes of radio frames associated with the one or more neighboring cells operate as downlink subframes. In response to the determining condition being met, allocating a first flexible subframe of a first radio frame associated with the first cell to operate as a downlink subframe at normal transmit power level. In response to the determining condition not being met, allocating the first flexible subframe of the first radio frame associated with the first cell as one of a downlink subframe operating in a reduced transmit power level or as an uplink subframe. | 08-01-2013 |
20130288608 | APPARATUS AND METHOD TO ENABLE DEVICE-TO-DEVICE (D2D) COMMUNICATION IN CELLULAR NETWORKS - An apparatus and method of allowing user equipment to transmit information directly with other user equipment, using a device-to-device mode is disclosed herein. A device-to-device blank subregion is defined where device-to-device information can be transmitted without interference from other user equipment. The device-to-device blank subregion may be set up such that it is only used in an exclusive mode if a device-to-device cluster is considered highly interfering. A device may join a device-to-device network through the use of a beacon transmission interval, a control transmission interval, and a data transmission interval. | 10-31-2013 |
20130322235 | ADAPTIVE UL-DL CONFIGURATIONS IN A TDD HETEROGENEOUS NETWORK - Technology for traffic offloading to generate a low interference flexible subframe (FlexSF) of an adaptive uplink-downlink (UL-DL) time-division duplexing (TDD) subframe configuration in a heterogeneous network (HetNet) is disclosed. One method can include an evolved Node B (eNB) monitoring a traffic loading metric for a specified traffic loading condition. The eNB can offload traffic scheduled for a packet of a macro user equipment (UE) from a macro cell to a FlexSF of a UL-DL subframe configuration of a small cell when the specified traffic loading condition exists. The eNB can be a macro eNB of the macro cell or a small eNB of the small cell. | 12-05-2013 |
