摘要： A method in a first base station having a first coverage area at least partly overlapping with a second coverage area of a second base station, the first base station operating within a first transmission power range and the second base station operating within a second transmission power range. The method includes determining radio link quality of a user equipment (UE1) connected to the first base station and being located in an adjustable extended coverage range of the second base station; requesting from the second base station, interference related measurements for unused physical channels or for physical channels at least partially overlapping with physical channels used by UE1 and having the radio link quality falling below a threshold value; and deciding for UE1, based on the interference related measurements, whether a handover to the second base station should be performed.

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 present solution relates to a method in a first communication node (201) for determining an indication of channel quality of a radio channel (205) between the first communication node (201) and a second communication node (203). The first communication node (201) and the second communication node (203) are comprised in a wireless communication network (200). The radio channel (205) comprises a plurality of sub bands. First, at least two channel quality reports are obtained (701) for different time instances. Each channel quality report comprises indications of channel quality of at least two of the plurality of sub bands. Then a channel quality deviation is estimated (702) for at least one of the plurality of sub bands. Further, an indication of a channel quality is determined (703) for at least one of the plurality of sub bands based on the estimated channel quality deviation.

摘要： For uplink cooperation of a serving access node (100-1) one or more supporting access nodes (100-2) are selected. The selection is based on a characteristic of a link between a terminal (200) served by the serving access node (100-1) and the supporting access node (100-2), or is based on a characteristic of a link between a further terminal (200′) served by the supporting access node (100-2) and the serving access node (100-1). The characteristics of the links may comprise a signal quality, e.g. a path gain, a signal strength, or a latency. The characteristics of the links may also comprise scheduling information, e.g. time resources and/or frequency resources used on the link.
