20130331115 | COMMUNICATION OF DATA USING INDEPENDENT DOWNLINK AND UPLINK CONNECTIONS - In communication of data between a first base station and a mobile terminal, a second base station may handle uplink transmissions from the mobile terminal. For this purpose, the first base station sends, to the second base station, a request to handle the uplink transmissions from the mobile terminal. The handling of the uplink transmissions to be performed by the second base station includes scheduling of the uplink transmissions so as to obtain uplink scheduling information. Via a backhaul link, the second base station transmits the uplink scheduling information to the first base station. The first base station includes the uplink scheduling information into downlink transmissions to the mobile terminal. | 12-12-2013 |
20130337795 | COMMUNICATION OF DATA USING INDEPENDENT DOWNLINK AND UPLINK CONNECTIONS - In communication of data between a first base station and a mobile terminal, a second base station may handle uplink transmissions from the mobile terminal. For this purpose, the first base station sends, to the second base station, a request to handle the uplink transmissions from the mobile terminal. Further, the first base station sends carrier information to the second base station. The carrier information indicates one or more uplink carriers for receiving the uplink transmissions. The one or more uplink carriers are controlled by the second base station. Moreover, the first base station sends downlink transmissions to the mobile terminal. The downlink transmissions include configuration data. By means of the configuration data, the mobile terminal is configured to send uplink transmissions on the one or more uplink carriers as indicated by the carrier information, e.g., on an uplink payload channel controlled by the second base station. | 12-19-2013 |
20140233457 | SYSTEMS AND METHODS OF TRIGGERING INTERFERENCE MITIGATION WITHOUT RESOURCE PARTITIONING - Systems and methods for triggering interference mitigation at a wireless device in a cellular communications network are disclosed. In one embodiment, a node associated with a cellular communications network makes a determination to trigger interference mitigation at a wireless device based on a signal load in at least one interfering cell from which transmissions result in interference at the wireless device during reception from a desired cell, a relation between reference signals used in the desired cell and the at least one interfering cell, and a timing relation between at least one of a group consisting of: signals transmitted by the desired cell and the at least one interfering cell and signals received at the wireless device from the desired cell and the at least one interfering cell. In response to making the determination, the node triggers interference mitigation at the wireless device. | 08-21-2014 |

20150111609 | METHODS AND ARRANGEMENTS FOR CONTROLLING TRANSMIT POWER IN A RADIO BASE STATION - A method for controlling transmit power in a wireless communication system are disclosed. The method comprises determining a first transmit power of at least a first type of subframe which is higher than a maximum allowed average output power of the radio base station, and a second transmit power of at least a second type of subframe which is lower than the maximum allowed average output power. An average transmit power by which the radio base station transmitted an amount of subframes during a preceding time period is determined. Moreover, a maximum allowed power for a subsequent subframe based on the determined average transmit power and the maximum allowed average output power is determined. Finally, at least one type of subframe to be allowed for the subsequent subframe based on the determined maximum allowed power for the subsequent subframe and at least the first and second transmit power is determined. | 04-23-2015 |
20150208410 | Nodes and Methods Therein for Managing Time-Frequency Resources - Method in a first node for managing time-frequency resources. The first node is comprised in a wireless network. The first node serves at least one user equipment in the wireless network. The first node determines a blanking ratio of a low interference time-frequency resource pattern, and/or an amount of required protected time-frequency resources. The determining is based on one or more parameters related to the user equipment served by the first node. The determining is for recommending to a second node comprised in the wireless network, and using the low interference time-frequency resource pattern. The first node signals information to the second node. The information comprises at least one of: the determined blanking ratio, the determined required amount of protected time-frequency resources, and the one or more parameters. The at least one user equipment served by the first node receives interference from the second node. | 07-23-2015 |
