1. An apparatus for wireless communication, comprising:
a processing system configured to:
receive, through a first interface, information obtained from another apparatus indicating a configured subset of a set of transmit (TX) beams at the another apparatus;
receive, through the first interface, a first set of pilot signals obtained from the another apparatus corresponding to the configured subset of the set of TX beams, each of a set of signal strength values being associated with receiving at least one of the first set of pilot signals; and
receive, through the first interface, a second set of pilot signals via the set of TX beams; and
a second interface connected to the processing system and configured to:
transmit, to the another apparatus, information associated with a set of beam pairs of the apparatus and the another apparatus,
wherein the configured subset of the set of transmit (TX) beams is configured, by the another apparatus, in accordance with: comparing a norm of an error matrix, associated with an identity matrix and the set of TX beams of the set of beam pairs of the apparatus and the another apparatus, with a threshold.
