摘要： The invention provides a method for self-interference suppression in a multi-antenna device that is part of a communication channel between a transmitter and a receiver of a wireless communication system. The communication system uses the multi-antenna device, the multi-antenna device is located between the transmitter and the receiver and uses antennas and a relay unit forwarding signals from the transmitter to the receiver. The communication channel has a transmit channel, defined by a transmit channel matrix between the transmitter and the multi-antenna device, a receive channel defined by a receive channel matrix, between the multi-antenna device and the receiver and a self-interference channel between an output and an input side of the multi-antenna device. The self-interference channel is defined by a self-interference channel matrix wherein the method comprises the steps of: • quipping the multi-antenna device with at least three antennas and; • suppressing the self-interference channel by using at least one filtering matrix arrangement being inserted between the antennas and the relay unit. The invention also provides a node in a wireless communication system comprising the multi-antenna device for self-interference suppression in the multi-antenna device module that is part of a communication channel.

摘要： Embodiments herein relate to a radio network node for scheduling a radio resource within a radio communications network. The radio network node comprises at least two antenna ports over which communication is performed using a respective power amplifier over each antenna port out of the at least two antenna ports. The radio network node determines a utilization factor of power of each power amplifier when a first user equipment is assigned to the radio resource. The radio network node further determines a utilization factor of power of each power amplifier when a second user equipment is assigned to the radio resource. The radio network node then schedules the first user equipment or the second user equipment to the radio resource based on the determined utilization factors.

摘要： An antenna arrangement including at least two antenna functions arranged to cover a certain angular sector, each antenna function comprising a corresponding antenna port. The antenna arrangement is configured to perform: a first direction of arrival (DOA) estimation for a transmitting device at a first frequency, and a second DOA estimation for the transmitting device at a second frequency, wherein the second frequency has a larger magnitude than the first frequency, and wherein at least one second frequency grating lobe is apparent in the angular sector at the second frequency. The antenna arrangement is configured to: distinguish the at least one second frequency grating lobe from a second frequency main lobe using results from the first DOA estimation, and identify a pointing direction of the second frequency main lobe as a resulting DOA estimation. Related methods are also described.
