Document Type and Number:
Japanese Patent JP6517937
Kind Code:
B2
Abstract:
A wireless device and a method therein for assisting in precoder selection for wireless communication with a Radio Node (RN), and a RN for performing precoder selection for wireless communication with a wireless device. The wireless device is configured with a set of precoders. The wireless device determines a subset of precoders out of the set of precoders; and transmits, to the RN, at least one Sounding Reference Signal (SRS) precoded with a respective at least one precoder comprised in the subset. The RN receives, from the wireless device, at least one SRS precoded with a respective at least one precoder comprised in a subset of precoders; and transmits, to the wireless device, a signal indicative of a selected precoder to be used for a transmission to the RN, wherein the selected precoder is indirectly selected based on the received at least one SRS.
