## Abstract

A wireless device receives at least one message comprising configuration parameters of a plurality of cells being in a cross-carrier scheduling group comprising a first cell and a second cell. The first cell identified by a first cell identifier employs a first number of bits. The configuration parameters indicate that the second cell is a cross-carrier scheduling cell for the first cell. The configuration parameters comprise the first cell identifier and a first cell indicator field. The first cell indicator field employs a second number of bits. The wireless device receives downlink control information via a control channel of the second cell for a packet transmitted via the first cell. The downlink control information comprises the first cell indicator field identifying the first cell. The wireless device receives the packet on the first cell via radio resources identified by the downlink control information.
