Original Abstract Submitted
there is provided mechanisms for detecting a signal communicated by a backscattering device. a method is performed by a mimo reader that comprises a first antenna panel and a second antenna panel. the method comprises selecting, for the first antenna panel, first spatial filter coefficients with an object to minimize interference from the first antenna panel towards the second antenna panel over a radio propagation channel. the method comprises transmitting, from the first antenna panel and whilst applying the selected first spatial filter coefficients, a first signal. the method comprises receiving, at the second antenna panel, a backscattered signal component of the first signal as backscattered by the backscattering device. the backscattered signal component comprises the signal communicated by the backscattering device. the mimo reader thereby detects the signal communicated by the backscattering device.
