Patent ID: 10141988

Abstract:
A method and a first radio node (200 or 202), for communicating data with a second radio node in a wireless network using precoders. The first radio node (200 or 202) communicates (2:1) with the second radio node (202 or 200) a first data transmission using a first set of precoders (S1), and communicates (2:4) with the second radio node (202 or 200) a precoder indicator which is based on quality of the communicated first data transmission. The first radio node (200 or 202) identifies (2:5) a second set of precoders (S2) within the first set (S1) based on the communicated precoder indicator, and communicates (2:6) with the second radio node (202 or 200) a second data transmission using the second set of precoders.
