1. An apparatus for wireless communications, comprising:
first and second ports;
a first interface configured to provide first intermediate signals corresponding to a first known sequence to a first radio frequency (RF) module for generating first RF signals to be output for transmission via a first antenna element;
a second interface configured to obtain second intermediate signals, wherein the second intermediate signals were generated by a second RF module based on the first RF signals as received via a second antenna element; and
a processing system configured to,
determine which of the first and second ports is coupled to at least one of the first RF module or the second RF module, wherein the determination is based on the first and second intermediate signals, and
configure at least one of:
the first RF module if it is determined the first or second port is coupled to the first RF module; or
the second RF module if it is determined the first or second port is coupled to the second RF module.
