摘要： A method in a base station for calculating a power relating to a first radio access is provided. The power is to be shared with a second radio access within the base station. The base station communicates with a number of user equipments using the first radio access. When the base station has estimated a statistic power distribution of transmit power to said user equipments during a time interval, it calculates a margin of power not to be shared with the second radio access, based on the estimated statistic power distribution. The base station further calculates a power to be shared with the second radio access, based on said margin of power.

摘要： According to some embodiments, there is provided a base station system configured to, among other things, (a) detect whether a particular UE is using too much power to transmit uplink data and (b) in response, transmit a message to the UE instructing the UE to detect a power control RS (PCRS) that is intended only for the particular UE. In some embodiments, the PCRS is transmitted such that the power (actual or nominal) of the PCRS as received by the UE is higher than the power of the previous CRS detected by the UE, thereby leading the UE to calculate a lower PL value, which can lead to the UE lowering its output power.

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.
