摘要： A method is disclosed which is performed in a transmitter device configured for transmission of measurement signals for beam selection. The method comprises determining a collection of linear combinations of transmission beams, wherein the transmission beams are of a set of available transmission beams. A cardinality, R, of the collection of linear combinations of transmission beams is lower than a cardinality, N, of the set of available transmission beams. Each transmission beam in the set of available transmission beams is comprised in at least one linear combination of transmission beams, and at least one of the linear combinations of transmission beams comprises less than all transmission beams of the set of available transmission beams. The method also comprises transmitting measurement signals to a receiver device, wherein each of the measurement signals corresponds to a linear combination of transmission beams from the collection of linear combinations of transmission beams. A method is also disclosed which is performed in a receiver device configured for performing measurements for beam selection. The method comprises receiving the measurement signals from a transmitter device, and performing measurements for beam selection on the measurement signals, for selection of a transmission beam from the set of available transmission beams. Corresponding apparatuses, communication devices, system, and computer program product are also disclosed.

摘要： This disclosure presents a method (600) of skipped channel buffering performed by a wireless device configured to receive downlink, DL, transmissions in multiple beams from a network node. The method (600) comprises monitoring (610) a beam scheduling of the network node and, based on the monitoring (610), determining (620) a probability that a current DL channel transmission is scheduled in a default beam. Responsive to the probability that the current DL channel transmission is scheduled in the default beam is at or below a scheduling threshold, skipping (630) buffering of DL channel transmissions in the default beam. A wireless device, a computer program product and a carrier are also disclosed.

摘要： A method of beamforming calibration is disclosed for a multi-antenna transceiver configured to communicate with one or more other transceivers. The multi-antenna transceiver has a plurality of transceiver chains connectable to respective antenna elements of the multi-antenna transceiver. Each transceiver chain comprises a transmitter path and a receiver path. The method comprises (for each transceiver chain) feeding an analog signal from the transmitter path to the receiver path via connection circuitry between the transmitter path and the receiver path to provide a digital calibration signal, and determining a beamforming calibration factor for the transceiver chain based on the digital calibration signal. Corresponding apparatus, multi-antenna transceiver, wireless communication node, and computer program product are also disclosed.
