摘要： A method and an arrangement (500) in a radio network node (130) for redistributing resources between at least a first and second communication device (110, 120) are provided. The radio network node (130) obtains a first estimate of a first signal quality for the first communication device (110) and a second estimate of a second signal quality for the second communication device (120). The radio network node (130) determines a first required signal quality for the first communication device (110) and a second required signal quality for the second communication device (120). When the first required signal quality is less than the first estimate and the second required signal quality is greater than the second estimate, the radio network node (130) allocates resources to the first and second communication devices (110, 120) such that the first signal quality decreases and such that the second signal quality increases.

摘要： According to embodiment of the present invention, there is provided a radio base station (20) and a corresponding method for estimating the quality of the uplink control channel. The method comprises measuring (32, 42) a quality parameter of the uplink data channel, and using (38, 50) this to estimate the quality of the uplink control channel. In one embodiment, measurements of the uplink control channel are taken and their reliability determined. If the reliability is low (i.e. below a threshold, or below the respective measurements taken on the uplink data channel), then measurements on the data channel are used instead of those made on the control channel to estimate the control channel quality.

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.
