A wireless device receives one or more radio resource control (RRC) messages. The one or more RRC messages comprise configuration parameters, for physical uplink shared channel (PUSCH), indicating: a plurality of power control parameter sets; and a plurality of pathloss reference signals (RSs). A medium access control control element (MAC CE) is received. The MAC CE indicates: an identity of a power control parameter set of the plurality of power control parameter sets; and a pathloss RS, of the plurality of pathloss RSs, associated with the power control parameter set. A downlink control information is received. The downlink control information indicates: the identity of the power control parameter set; and one or more uplink resources of the PUSCH. A transport block with a transmission power determined based on the pathloss RS associated with the power control parameter set is transmitted via the one or more uplink resources.

Apparatus and methods for envelope alignment calibration in radio frequency (RF) systems are provided. In certain embodiments, calibration is performed by providing an envelope signal that is substantially triangular along an envelope path, and by providing an RF signal to a power amplifier along an RF signal path. Additionally, an output of the power amplifier is observed to generate an observation signal using an observation receiver. The observation signal includes a first peak and a second peak, and a delay between the envelope signal and the RF signal is controlled based on relative size of the peaks of the observation signal to one another.
