    摘要: A technique is provided for use by a Multi-Radio Management Resource (MRRM) component of a multi-radio wireless communication system for controlling the handover of a mobile terminal between different radio access technologies (RAT). In one example, all suitable RATs having coverage areas currently covering the location of a mobile terminal are identified. The performance gain that might be achieved via a handover to one of the other RATs is then determined by the MRRM based on various performance gain factors. Handover costs that will be incurred as a result of the handover are also explicitly calculated. Then, a cost-adjusted gain is determined by the MRRM based on the performance gain and the handover costs. A handover is only triggered by the MRRM if the cost-adjusted gain exceeds a minimum threshold. The speed and trajectory of the mobile terminal may also be considered.

    摘要: A method and arrangement for enabling communication of data between a UE and a first base station in a cellular communication network further comprising the second base station, and the second base station is connected to the first base station via a communication interface. A scheduling request is received from the first base station. The scheduling request is based on a suggested scheduling which is determined by the first base station, and the suggested scheduling concerns the communication of data. Scheduling information is determined based on the scheduling request, and the scheduling information is transmitted to the UE. By determining a suggested scheduling in a micro base station, but transmitting scheduling information from an overlaying macro base station, local awareness of communication conditions may be applied, and interferences from neighboring micro base stations may be decreased.

    摘要: A radio network resource controller directs a first network node associated with a first cell region, or a wireless terminal in communication through the first cell region, to measure and report radio resource-related data selected from the group consisting of: resource activity per channel; the number of transmitted power samples that exceed a threshold over a measurement period; and, channel quality samples that exceed a quality threshold. The controller then receives at least one measurement report of the radio resource-related data and, as a function of the radio resource-related data in the first cell region, dynamically reallocates the distribution of resources, such as radio-frequency channels, between the first cell region and at least a second cell region. The invention has a particular advantage in TDD mode of operation where efficient and dynamic interference mitigation is needed to combat the inherent mobile-to-mobile and base station-to-base station interference.
