Claim 18:
19. A non-transitory computer-readable medium storing code for wireless communication at a user equipment (UE), the code comprising instructions executable by a processor 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 using 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 belonging to at least one other group of antenna ports;
generate, from the uplink data, a plurality of output signals corresponding to the plurality of antenna ports based at least in part on applying the closed-loop MIMO scheme for the plurality of groups of antenna ports; and
transmit the plurality of output signals using the plurality of antenna ports.
