1. 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 at least one message comprising;
configuration parameters for each carrier of a plurality of carriers, the plurality of carriers comprising;
at least one carrier of a first carrier type; and
at least one carrier of a second carrier type, different from the first carrier type, wherein the at least one carrier of the second carrier type comprises lower downlink common reference signal overhead than the at least one carrier of the first carrier type;
information indicating whether each carrier of the plurality of carriers is of the first carrier type or the second carrier type; and
information associating one of the at least one carrier of the second carrier type with one of the at least one carrier of the first carrier type; and
transmit channel state information of the one of the at least one carrier of the second carrier type via an uplink carrier of the one of the at least one carrier of the first carrier type.

Abstract
A wireless device receives control messages comprising configuration parameters of a plurality of carriers comprising at least one backward compatible carrier and at least one non-backward compatible carrier. The control messages comprise information indicating a carrier type and information associating at least one of said at least one non-backward compatible carrier with one of said at least one backward compatible carrier. The wireless device transmits channel state information of one of said at least one non-backward compatible carrier on an uplink carrier of one of said at least one backward compatible carrier.
