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 method is provided in a base station for handling a request from a first user equipment for accessing a service in a radio communications network. The method comprises the steps of receiving a first time interval of an incoming signal comprises a first signal sent from the first user equipment and a second signal sent from the second user equipment, interpreting the first signal as being a possible service access request message preamble, and sending an acknowledgement, that the preamble is detected, to the first user equipment. The method comprises the further steps of delaying the first time interval of the incoming signal, identifying the second signal in the first time interval of the incoming signal during the delay, washing the identified second signal away from the first time interval of the incoming signal during the delay, and deciding whether the possible preamble is a real preamble or not, by analyzing the washed incoming signal.
