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： 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.
