Claim 0:
1. An apparatus for wireless communication at a user equipment (UE), comprising:
a processor;
memory coupled with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
receive, from a base station, an indication that the UE is to use a closed-loop multiple-input multiple-output (MIMO) scheme for transmissions of uplink data via a plurality of antenna ports, wherein the plurality of antenna ports include a plurality of groups of antenna ports, wherein antenna ports within a group of antenna ports are phase coherent with each other antenna port belonging to the group of antenna ports, and wherein the antenna ports within the group of antenna ports are phase incoherent with antenna ports that belong to at least one other group of antenna ports;
generate, from the uplink data, a plurality of output signals that correspond to the plurality of antenna ports based at least in part on application of the closed-loop MIMO scheme for the plurality of groups of antenna ports; and
transmit the plurality of output signals via the plurality of antenna ports.
