Abstract
A user equipment (UE) with N transmit (Tx) antenna elements in a wireless network receives precoding information from a base station. The UE constructs a full-rank complex Hadamard matrix (CHM) of order N using the precoding information. The UE then precodes uplink signal using a precoding matrix composed of one or more columns of the full-rank CHM, and transmits the precoded uplink signal to the base station.
