Abstract
According to some embodiments, a method performed by a wireless device for transmitting multiple layers of an uplink physical channel comprises transmitting to a network node an indication of a capability to operate according to a first mode of operation and a second mode of operation. In the first mode a codebook subset comprises precoding matrices with at most one non-zero elements per column, and in the second mode the codebook subset comprises precoding matrices with at most two non-zero elements per column. The codebook subset is in a codebook for use when transform precoding of a physical channel is disabled. The method further comprises receiving a configuration from the network node for a selected mode of operation, and transmitting the physical channel using transform precoding and, at least when transmitting with two layers, using the codebook subset comprising the precoding matrices of the selected mode.
