Patent ID: 8711727

Claim:
An apparatus comprising: a measuring unit configured to measure attenuation from a plurality of sub-bands of a frequency spectrum in which a physical uplink control channel is being transmitted; and a calculating unit configured to calculate a path loss measurement as an average of the measurement of said attenuation from each of the plurality of sub-bands of the frequency spectrum, wherein power control for said physical uplink control channel is calculated using the following formula: P =min( P max ,10 log 10( M )+ P o +αPL+Δ mcs +f (Δ j )), where P max is a maximum allowed user equipment power, M is a number of assigned resource blocks, α is a path loss compensation factor, P o is a cell and user equipment specific scaling parameter, PL is the downlink path loss measured at the user equipment, Δ mcs is MCS specific value, and f(Δ i ) is a user equipment specific closed loop correction value.
