Abstract: There is provided mechanisms for reporting a faulty antenna port at a transmitting radio device. A method is performed by a receiving radio device. The method comprises receiving at least one reference signal transmitted at an antenna port of the transmitting radio device. The method comprises determining whether the antenna port is deemed faulty or not by subjecting the at least one reference signal to an evaluation criterion. The method comprises transmitting, when the antenna port is deemed faulty, a report to the transmitting radio device. The report indicates that the antenna port is deemed faulty.

Abstract: The disclosure relates to a method (20) for initiating a blind handover of a terminal (2) in a wireless communications system (1). The terminal (2) is served by a first cell using a first frequency band and a first radio access technology, wherein the wireless communications system (1) employs a method for dynamically changing coverage in at least one of the first cell and a second cell. The method (20) comprises estimating (21) the coverage in the second cell, wherein at least one of a second frequency band and a second radio access technology of the second cell may differ from the first frequency band and the first radio access technology, an initiating (22) the blind handover for the terminal (2) to the second cell only if the estimated coverage in the second cell meets a criterion. A wireless communications system (1), computer programs and computer program products are also provided.
