摘要： Method and arrangement in a relay node, for selecting communication mode. The relay node is configured to communicate with a base station via a donor antenna over a first link and to communicate with a user equipment via a coverage antenna over a second link. The method comprises obtaining an isolation value, based on the radio wave isolation between the relay donor antenna and the relay coverage antenna. The obtained isolation value is compared with an isolation threshold level value. The relay node is configured to communicate in full duplex mode if the obtained isolation value exceeds the isolation threshold level value, otherwise in half duplex mode. Information concerning the configured duplex mode of the relay node is transmitted to the base station. Also a method and arrangement in a base station is described.

摘要： A method for power measurements in a cellular communication system comprises receiving (222) measurement configuration orders. Operation of a power meter is controlled (224) in dependence on the measurement configuration orders. Reference signal received powers are measured (226).

摘要： In a receive node (230) of a wireless network (100), an iterative multi-user multi-stage interference cancellation receiver (500, 1400, 1700) is used. The receiver (500, 1400, 1700) performs code-averaged equalization and chip chip-level code-specific interference over-cancellation on the received signals. This can result in a unified interference cancellation processing, and can avoid cumbersome calculations of code cross correlations that is required in symbol-level interference cancellation. A symbol-level code-averaged desired signal add-back is performed to address the over- cancellation of some desired signals.

摘要： The object of the present invention is to provide a mechanism for a more efficient carrier search. The object is achieved by a method for sending a signal in a first node. The first node communicates with a second node via radio communication, which radio communication is performed by multi carrier transmission. The first node uses a carrier, being associated with a frequency range. The method comprises the step of transmitting an end-marker signal within or close to the frequency range. The end-marker signal is intended to be received and used by the second node for identifying the frequency range of the used carrier.
