Wireless device and wireless network processes for enhanced scheduling
A wireless device may receive message(s) comprising configuration parameters of multiple cells. The wireless device may receive a first DCI indicating scheduling information. The wireless device may determine, based at least on one of the first DCI and a second downlink control parameter, whether the first DCI is for scheduling TB(s) via a single cell, in the multiple cells, or for scheduling TBs via the multiple cells. The wireless device may transmit or may receive the TBs via the multiple cells based on the scheduling information and in response to the determining indicating that the first DCI is for scheduling the TBs via the multiple cells.
