Abstract

The present invention provides a method of wireless communication involving at least one first uplink channel associated with a first protocol and at least one second uplink channel associated with a second protocol. The method may include providing signaling information associated with the first uplink channel over a signaling channel associated with the at least one second uplink channel in response to determining that the signaling channel associated with the at least one second uplink channel is available.

Claims (19)

1. A method of wireless communication between a base station and a mobile unit involving at least one first uplink channel associated with a first protocol and at least one second uplinik channel associated with a second protocol, the first uplinik channel configured to provide data for transmission to the base station over at least one first data channel and signaling information for transmission to the base station over at least one first signaling channel, and the second uplinik channel configured to provide data for transmission to the base station over at least one second data channel and signaling information for transmission to the base station over at least one second signaling channel, the method comprising:

determining whether the second signaling channel is available;

transmitting data over said at least one first data channel of the first uplinik channel;

providing, concurrently with transmitting the data over said at least one first data channel, signaling information associated with the first uplinik channel to the base station over said at least one second signaling channel associated with said at least one second uplinik channel when the second signaling channel associated with said at least one second uplink channel is available; and

providing, concurrently with transmitting the data over said at least one first data channel, signaling information associated with the first uplink channel to the base station over said at least one first signaling channel when the second signaling channel is not available.

2. The method of claim 1 , wherein providing signaling information associated with the first uplink channel comprises providing at least one of transmission format control information, transmit power control information, and hybrid automatic repeat request information.

3. The method of claim 2 , wherein providing said signaling information over the second signaling channel associated with said at least one second uplinik channel comprises providing said signaling information over a second signaling channel used to provide at least one of transmission format control information and transmit power control information associated with said at least one second data channel when said at least one second uplinik channel is active.

4. The method of claim 1 , comprising mapping said at least one first signaling channel associated with said at least one first uplinik channel to said at least one second signaling channel associated with said at least one second uplinik channel in response to determining that said at least one second uplinik channel is idle.

5. The method of claim 4 , wherein mapping said at least one first signaling channel associated with said at least one first uplinik channel comprises mapping at least one of the transport format control information and the RSN information to a transport format control information field in said at least one second signaling channel associated with said at least one second uplink channel.

6. The method of claim 1 , comprising determining that said at least one second signaling channel associated with said at least one second uplinik channel is available.

7. The method of claim 6 , wherein determining that said at least one second signaling channel associated with said at least one second uplinik channel is available comprises determining that said at least one second uplinik channel is idle.

8. A method of wireless communication between a base station and a mobile unit involving at least one first uplink channel associated with a first protocol and at least one second uplinik channel associated with a second protocol, the first uplinik channel configured to provide data for transmission to the base station over at least one first data channel and signaling information for transmission to the base station over at least one first signaling channel, and the second uplinik channel configured to provide data for transmission to the base station over at least one second data channel and signaling information for transmission to the base station over at least one second signaling channel, the method comprising:

receiving data over said at least one first data channel of the first uplink channel;

receiving, concurrently with receiving the data over said at least one first data channel, signaling information associated with the first uplink channel over said at least one second signaling channel associated with said at least one second uplink channel when said at least one second signaling channel associated with said at least one second uplink channel is available because said at least one second uplink channel is idle; and receiving, concurrently with transmitting the data over said at least one first data channel, signaling information associated with the first uplinik channel over said at least one first signaling channel when the second signaling channel is not available because said at least one second uplinik channel is in use.

9. The method of claim 8 , wherein receiving signaling information associated with the first uplinik channel comprises receiving at least one of transmission format control information, transmit power control information, and hybrid automatic repeat request information.

10. The method of claim 9 , wherein receiving said signaling information over said at least one second signaling channel associated with said at least one second uplinik channel comprises receiving said signaling information over at least one second signaling channel used to provide at least one of transmission format control information and transmit power control information associated with the second uplinik channel when the second uplinik channel is active.

11. The method of claim 8 , comprising decoding information received over the first uplink channel based on the signaling information provided over said at least one second signaling channel associated with said at least one second uplink channel.

12. The method of claim 8 , comprising determining that said at least one second signaling channel associated with said at least one second uplinik channel is available.

13. The method of claim 12 , wherein determining that said at least one second signaling channel associated with said at least one second uplinik channel is available comprises determining that said at least one second uplinik channel is idle.
