1. An apparatus for wireless communication, the apparatus comprising:
one or more processors;
memory coupled with the one or more processors; and
instructions stored in the memory and executable by the one or more processors, individually or collectively, to cause the apparatus to:
select a particular pre-coder from among a plurality of pre-coders;
initiate encoding of an uplink signal in accordance with the particular pre-coder to generate a pre-coded uplink signal, wherein the pre-coded uplink signal has one or more characteristics that enable a network node to identify the particular pre-coder; and
initiate transmission of the pre-coded uplink signal, wherein the one or more characteristics include one or more of a transmit power level associated with the encoded uplink signal, a transmit antenna associated with the encoded uplink signal, or a transmit port associated with the encoded uplink signal.
