摘要： Embodiments of the present disclosure provide a method, a transmitter node, a receiver node, and a computer program product for communication of information in a communication channel comprising at least one main band and an adjacent guard band. The method is performed by a transmitter node in a wireless communication network. The method comprises determining whether to transmit information in the guard band based one or more configured transmission parameters associated with the transmitter node. Upon determination to transmit information in the guard band, the method comprises determining transmission power for frequency resources allocated in the guard band based on a spectral mask defining a power density limit across an allocated frequency range. The method further comprises transmitting first information on the frequency resources allocated in the guard band and second information on frequency resources allocated in the main band to a receiver node according to the determined transmission power. Corresponding transmitter node, receiver node and computer program products 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.
