16. An apparatus for wireless communication at a user equipment (UE), the apparatus comprising:
a processor;
memory coupled with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
identify, by the UE, a transition from a first transmission strategy for a downlink channel to a second transmission strategy for the downlink channel based at least in part on a data transfer rate;
determine feedback information based at least in part on the second transmission strategy for the downlink channel; and
transmit, to a network device, a channel state information (CSI) message that includes the feedback information and a precoding matrix indicator (PMI) field, wherein the PMI field includes an indication of the second transmission strategy, and wherein the second transmission strategy is an open-loop multiple input multiple output (MIMO) transmission strategy.
