1. A method comprising:
- a) transmitting, by a base station, at least one control message to a wireless device, said at least one control message comprising;
i) an identifier for each carrier in a plurality of carriers, said plurality of carriers comprising;
(1) at least one backward compatible carrier; and
(2) at least one non-backward compatible carrier, a first common reference signal overhead of each of said at least one non-backward compatible carrier being substantially lower than a second common reference signal overhead of each of said at least one backward compatible carrier;
ii) information identifying a carrier type for each of said plurality of carriers, said carrier type being one of at least a backward compatible type and non-backward compatible type; and
iii) information associating each of said at least one non-backward compatible carrier with one of said at least one backward compatible carrier;
b) receiving, by said base station, channel state information of one of said at least one non-backward compatible carrier from said wireless device on an uplink carrier of one of said at least one backward compatible carrier;
c) transmitting, by said base station, a plurality of second control messages to said wireless device on a backward compatible carrier, said plurality of second control messages comprising scheduling information for transmission of packets on the non-backward compatible carrier associated with said backward compatible carrier; and
d) transmitting, by said base station, a plurality of packets to said wireless device on said non-backward compatible carrier according to said scheduling information.

Abstract
A base station configured to communicate over a plurality of carriers. The plurality of carriers comprise at least one backward compatible carrier and at least one non-backward compatible carrier. The base station transmits a control message to a wireless device. The control message comprises an identifier for a carrier and information identifying a carrier type. The carrier type is either a backward compatible type or a non-backward compatible type. The base station configured to transmit a plurality of packets to a wireless device on non-backward compatible carrier(s) and backward compatible carrier(s).

16. A base station comprising:
-
a) one or more communication interfaces; b) one or more processors; and c) memory storing instructions that, when executed, cause said base station to; i) transmit at least one control message to a wireless device, said at least one control message comprising; (1) an identifier for each carrier in a plurality of carriers, said plurality of carriers comprising; (a) at least one backward compatible carrier; and (b) at least one non-backward compatible carrier, a first common reference signal overhead of each of said at least one non-backward compatible carrier being substantially lower than a second common reference signal overhead of each of said at least one backward compatible carrier; (2) information identifying a carrier type for each of said plurality of carriers, said carrier type being one of a backward compatible type and non-backward compatible type; and (3) information associating each of said at least one non-backward compatible carrier with one of said at least one backward compatible carrier; ii) receive channel state information of one of said at least one non-backward compatible carrier from said wireless device on an uplink carrier of one of said at least one backward compatible carrier. - View Dependent Claims (17, 18, 19, 20)
