摘要： The present invention presents a method for controlling output power and reducing interference in a radio communications network wherein data transmitted over a radio interface is coded and transmitted in radio blocks. The data passes a buffer of a node before transmission. The method is characterized by a step of determining a recommended Modulation and Coding Scheme level, MCS level, based on at least one radio quality measurement. A further characterising step is analyzing of buffer characteristics and/or radio block usage of transmission radio blocks to determine if there is a preferred MCS level compared to the recommended MCS level. The preferred MCS level is typically a more robust MCS level. The recommended MCS, level if so determined, is decreased to the preferred MCS level, and in relation to decreasing the MCS level decreasing the output power according to a predefined down regulation scheme. The interference level is reduced in the network depending on an application type.

摘要： Methods and network nodes (110, 112), serving a user equipment (120), for deciding if a handover request of the user equipment (120) is to be sent to a candidate target network node (130-1, 130-2, 130-3). The methods comprise acquire (603) data-rate performance of a wireless link between the network nodes (110, 112) and the user equipment (120). The data-rate performance is compared (606) with a data-rate performance threshold value. If the acquired data-rate performance is lower than the data-rate performance threshold value, it is decided (607) to send the handover request of the user equipment (120) to the candidate target network node (130-1, 130-2, 130-3).

摘要： A low power RBS and a method therein for scheduling downlink transmission to a UE are provided. The low power RBS is associated to at least one macro RBS and the low power RBS is configured to provide radio coverage in a cell of a heterogeneous cellular communication network for scheduling downlink transmissions to a UE connected to the low power RBS. The method comprises receiving (210) a measurement report comprising a channel quality measurement from the UE and adjusting (220) a current SINR value based on the received measurement report for a period of an Almost Bland Subframe, ABS, of the macro RBS. The method further comprises determining (230) downlink transmission parameters based on the adjusted SINR value, and scheduling (240) a downlink transmission to the UE in a subframe of the low power RBS coinciding with an ABS of the macro RBS using the determined downlink transmission parameters.
