Abstract
Methods, apparatuses, and articles of manufacture are disclosed for adjusting a power level in connection with transmitting parallel uplink channels. In one aspect, a user equipment determines a power-limited condition in which a total transmit power of a group of power-controlled channels exceeds a maximum level in a transmission subframe. The user equipment may determine, in an iterative fashion, power backoff values by which to establish a configured maximum power level. The parallel uplink channels in the group may be prioritized and different backoff values may be used with channels having different priorities. The user equipment may thereafter adjust a transmit power of the power-controlled channels based on the configured maximum power level.
