Abstract
Embodiments presented herein relate to a method for reciprocity-based transmission in a radio communication network. The method is performed in a base station and may include obtaining a channel estimation of Rx quantities of a set of receive, Rx, and transmit, Tx, distribution networks, obtaining a channel estimation of Rx quantities of a set of Rx distribution networks, and performing reciprocity-based transmission with utilization of the obtained channel estimation of Rx quantities of both the set of Rx and Tx distribution network and the set of Rx distribution network, whereby channel estimation of Rx quantities of more Rx distribution networks than Tx distribution networks are utilized for the reciprocity-based transmission. A method, a base station, a wireless device, a computer programs and a computer program product for reciprocity-based beamforming in a radio communication network are also presented.
