    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: The invention provides an increase in the radio coverage area (10) of a base transceiver station (100) having access to multiple transceivers (102, 104, 106, 108) by dedicating at least one of the transceivers (102) for BCCH data. This BCCH transceiver (102) is connected to an antenna arrangement (120) 5 comprising at least two antenna elements (121, 123; 125, 127). Increased BCCH radio coverage (30) is achieved by providing antenna hopping among the at least two antenna elements (121, 123; 125, 127) for the BCCH. Correspondingly, increased TCH coverage (20) is achieved by providing frequency hopping among at least two carrier frequencies for the TCH. The 10 coverage (10) of the base transceiver station (100) is defined as the intersection of the BCCH radio coverage (30) and the TCH coverage (20).
