Abstract
Aspects presented herein may improve multiple-input multiple-output (MIMO) operations by providing a semi-open-loop MIMO scheme with a higher granularity. In one aspect, a network entity formulates, based on wideband (WB) channel state information of a channel from a user equipment (UE), a set of precoding matrices to be applied on a set of resource blocks (RBs) or a set of resource elements (REs) for a data channel transmission on the channel. The network entity precodes the set of RBs or the set of REs for the data channel transmission on the channel with the formulated set of precoding matrices and a set of phase values in a cycling manner. The network entity transmits, via the channel, an indication of the set of precoded RBs or the set of precoded REs.
