1. A method comprising:
receiving, by a wireless device, at least one message comprising configuration parameters of a first cell in a plurality of cells, the plurality of cells grouped into one or more cross-carrier scheduling groups comprising a first cross-carrier scheduling group, the first cross-carrier scheduling group comprising the first cell and a second cell, each of the first cell and the second cell identified by a respective cell identifier employing a first number of bits, wherein the configuration parameters:
indicate that the second cell is employed for cross carrier scheduling of the first cell; andcomprise a cell identifier and a first cell indicator field, the first cell indicator field employing a second number of bits, wherein the second number is smaller than the first number; receiving downlink control information on a control channel of the second cell for a packet transmitted on the first cell, the downlink control information comprising the first cell indicator field, the first cell indicator field identifying the first cell; and receiving the packet on the first cell on radio resources identified by the downlink control information. |
