Multiple Cells Scheduling with Hybrid Automatic Repeat Request

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 downlink control information:
• scheduling a first transport block via a first cell and a second transport block via a second cell;
• and
• comprising a hybrid automatic repeat request (HARQ) process number;
• and
• decode:
• the first transport block, received via the first cell, based on a first HARQ process identified by the HARQ process number;
• and
• the second transport block, received via the second cell, based on the first HARQ process and an offset value.
