Abstract
Network nodes, wireless devices and methods of reducing signaling overhead are provided. In one embodiment, a method includes transmitting to the wireless device at least one power threshold parameter to be used by the wireless device to determine a number of beams to be included in a multi-beam precoder codebook and transmitting to the wireless device a signal to interference plus noise ratio (SINR) to be used by the wireless device to determine to use one of a single beam precoder and a multiple beam precoder.

39. A method for a user equipment to adjust uplink signaling overhead, the method comprising:
-
receiving signaling that configures the user equipment with a first number of beams, N; determining N power values, each power value corresponding to one of the N beams; and including channel state information, CSI, in a CSI report, the CSI pertaining to one or more beams whose corresponding power value is above a predetermined power value. - View Dependent Claims (40, 41, 42, 43, 44, 45)
