Pathloss Estimation on Secondary Cells

A wireless device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
• receive one or more configuration parameters indicating:
• one or more first synchronization signal blocks (SSBs), of a cell, for transmission on-demand;
• and
• one or more second SSBs of the cell;
• and
• transmit an uplink signal based on a second SSB, of the one or more second SSBs, as a pathloss reference signal, wherein the second SSB has a same index as a first SSB of the one or more first SSBs.

A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:

• receive one or more configuration parameters indicating:
• one or more first synchronization signal blocks (SSBs), of a cell, for transmission on-demand;
• and
• one or more second SSBs of the cell;
• and
• transmit an uplink signal based on a second SSB, of the one or more second SSBs, as a pathloss reference signal, wherein the second SSB has a same index as a first SSB of the one or more first SSBs.
