Group power control for a secondary cell
First Claim
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.

Abstract
A wireless device may receive message(s) comprising configuration parameters for cells comprising a primary cell and a secondary cell. The configuration parameters may 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 the secondary cell. A first downlink control information (DCI) may be received indicating activation of the periodic resource allocation. A common search space for a second DCI associated with the TPC RNTI may be monitored. The second DCI may comprise a sequence of TPC commands. The secondary TPC index may identify a TPC command in the sequence. Transport blocks may be transmitted by employing transmission parameter(s) in the first DCI and the TPC command.
