Techniques to control uplink power

摘要

Techniques are described that provide uplink power control techniques that can support different uplink multi-input multi-output (MIMO) transmission schemes. Open and closed loop power control schemes can be used to prescribe the power level of the mobile station.

1. A mobile station comprising:
logic to receive, from a base station, a control factor determined from neighboring base station uplink interference levels for multiple-user multi-input multi-output (MU-MIMO) operations, a minimum signal to interference and noise ratio, a noise plus interference level information, a downlink preamble, and a Base Station Effective Isotropic Radiated Power (BS_EIRP) parameter; logic to determine estimated average uplink propagation loss from the downlink preamble and the BS_EIRP parameter received from the base station; and logic to determine an uplink transmit power per antenna using an open loop transmission power control calculation formula based in part on the control factor, minimum signal to interference and noise ratio, noise plus interference level information, and the estimate average uplink propagation loss.
