Abstract

A method and apparatus for uplink power control in multiple-input multiple-output (MIMO) includes adjusting a total uplink transmit power level with a power offset based on a number of antennas via which an uplink subframe is transmitted. The uplink power control formula may be altered to include an additional power offset term to compensate for a MIMO mode or an existing term may be adjusted to compensate for the MIMO mode.
