1. A method employed in wireless communication system, the method comprising:

  • transmitting at least one power control reference signal from an antenna selected from a group of M antennas, with M a positive integer;

    conveying a power spectral density (PSD) offset from the antenna employed to report the at least one power control reference signal, wherein the PSD offset is based at least in part on a reference PSD level for transmitting the at least one power control reference signal; and

    transmitting a pilot signal from each antenna in the set of M antennas for estimating a multiple-input multiple output channel when M>

    1, and a SIMO channel when M=1.
