1. A method comprising:

  • receiving, by a wireless device, one or more messages comprising configuration parameters for a plurality of cells comprising a primary cell and a secondary cell, wherein the configuration parameters comprise;

    a transmit power control (TPC) radio network temporary identifier (RNTI);

    a primary TPC index for a first physical uplink shared channel (PUSCH) of the primary cell;

    a secondary TPC index for a second PUSCH of the secondary cell; and

    periodic resource allocation configuration parameters configuring a periodic resource allocation for transmission of transport blocks via the second PUSCH of the secondary cell;

    receiving first downlink control information (DCI) indicating activation of the periodic resource allocation for transmission of transport blocks via the second PUSCH of the secondary cell;

    monitoring a common search space for a-second DCI associated with the TPC RNTI, wherein the second DCI comprises a sequence of TPC commands, and wherein the secondary TPC index indicates a TPC command in the sequence; and

    transmitting, via the second PUSCH and based on the first DCI and the TPC command, one or more transport blocks.
