Abstract

Methods (10, 30) and devices (20, 40) for performing radio transmissions in a wireless communication network are provided. A method (30) associated with a wireless terminal (40, 40A) which performs radio transmissions in the wireless communication network comprises: receiving (31) a multiple input multiple output, MIMO, transmission from an access node (20) of the wireless communication network; estimating (32) a spatial orientation (θ, (ϕ)) of an antenna array (42) of the wireless terminal (40, 40A) based on measurements performed by at least one sensor (43) of the wireless terminal (40, 40A); and based on the estimated spatial orientation (θ, (ϕ)), filtering out (33) a polarization crosstalk from the received MIMO transmission, the polarization crosstalk being associated with the spatial orientation (θ, (ϕ)) of the antenna array (42) of the wireless terminal (40, 40A).
