Control signal aggregation in a multi-carrier WCDMA system
First Claim
1. A method in a wireless transceiver for transmitting data to a remote node via each of two or more transmitted carrier signals, wherein a distinct outbound packet data traffic channel is mapped to each transmitted carrier signal, the method comprising:
- forming aggregated control channel data for the remote node by combining first control channel data corresponding to a first received carrier signal with second control channel data corresponding to a second received carrier signal, wherein a distinct inbound packet data traffic channel is mapped to each of the first and second received carrier signals;
simultaneously transmitting traffic channel data to the remote node on each of the two or more outbound packet data traffic channels; and
transmitting the aggregated control channel data for the remote node and aggregated control channel data for other remote nodes using one or more physical control channels mapped to a first one of the transmitted carrier signals.

Abstract
Methods and apparatus are disclosed for transmitting data to a remote node via each of two or more transmitted carrier signals, wherein a distinct outbound packet data traffic channel is mapped to each transmitted carrier signal. In an exemplary method, aggregated control channel data is formed by combining control channel data corresponding to each of two or more received carrier signals, simultaneously transmitting traffic channel data to the remote node on each of the two or more outbound packet data traffic channels, and transmitting the aggregated control channel data using one or more physical control channels mapped to a first one of the transmitted carrier signals. In particular, these methods and apparatus may be applied to a multi-carrier High-Speed Packet Access (HSPA) system.

11. A wireless transceiver comprising a transmitter circuit configured to transmit data to a remote node via two or more distinct outbound packet data channels mapped to corresponding transmitted carrier signals, a receiver circuit configured to receive first and second distinct inbound packet data traffic channels mapped respectively to first and second received carrier signals, and a control circuit configured to:
-
form aggregated control channel data for the remote node by combining first control channel data corresponding to the first received carrier signal with second control channel data corresponding to the second received carrier signal; simultaneously transmit traffic channel data to the remote node on each of the two or more outbound packet data traffic channels, via the transmitter circuit; and transmit the aggregated control channel data for the remote node and aggregated control channel data for other remote nodes using one or more physical control channels mapped to a first one of the transmitted carrier signals, using the transmitter circuit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
