Abstract
A Radio Network Node (RNN) and a method for enabling an improved reception of Positioning Reference Signals (PRSs) at a communications device. The RNN and the communications device are operable in a wireless communications network. The RNN selects a first precoder and a second precoder for forming a first beam and a second beam, respectively, and obtains a precoding switching pattern relating to when the first precoder is to be applied to one or more first PRS symbols and when the second precoder is to be applied to one or more second PRS symbols. Further, the RNN transmits, to the communications device, the one or more first PRS symbols to which the first precoder is applied; and in accordance with the obtained precoding switching pattern, the RNN transmits, to the communications device, the one or more second PRS symbols to which the second precoder is applied.
