Uplink control signal design for wireless system
View Patent ↗The present disclosure generally relates to an uplink control signal design for wireless system. One example method includes establishing communication with a mobile station in a multi-carrier wireless communication system using a primary carrier, providing a first control signaling via the primary carrier, the first control signaling assigning at least one secondary carrier, and receiving a channel quality indication of the secondary carrier via the primary carrier using a control channel.
1. A method in a base station, the method comprising:
establishing communication with a mobile station in a multi-carrier wireless communication system using a primary carrier;
providing a first downlink control signaling via the primary carrier, the first control signaling assigning at least one secondary carrier;
receiving a channel quality indication via the primary carrier using an uplink control channel, said channel quality indication corresponding to the secondary carrier;
providing timing information corresponding to the primary carrier; and
receiving uplink data via the secondary carrier, the timing of the uplink transmission based on the timing information corresponding to the primary carrier.
2. The method of claim 1 , wherein the primary carrier corresponds to the carrier used for network entry by the mobile station.
3. The method of claim 1 , wherein the primary carrier contains a synchronization channel.
4. The method of claim 1 , further comprising providing a second control signaling via the primary carrier, the second control signaling changing the primary carrier.
5. The method of claim 1 , further comprising providing a message assigning the control channel.
6. The method of claim 1 , wherein the multi-carrier wireless communication system employs orthogonal frequency division multiplexing.
7. An apparatus comprising:
a transceiver; and
a processor configured to:
establishing communication with a mobile station in a multi-carrier wireless communication system using a primary carrier;
providing a first downlink control signaling via the primary carrier, the first control signaling assigning at least one secondary carrier;
receiving a channel quality indication via the primary carrier using an uplink control channel, said channel quality indication corresponding to the secondary carrier;
provide timing information corresponding to the primary carrier; and
receive uplink data via the secondary carrier, the timing of the uplink transmission based on the timing information corresponding to the primary carrier.
8. The apparatus of claim 7 , wherein the primary carrier corresponds to the carrier used for network entry by the mobile station.
9. The apparatus of claim 7 , wherein the primary carrier contains a synchronization channel.
10. The apparatus of claim 7 , the processor further configured to provide a second control signaling via the primary carrier, the second control signaling changing the primary carrier.
11. The apparatus of claim 7 , the processor further configured to provide a message assigning the control channel.
12. The apparatus of claim 7 , wherein the multi-carrier wireless communication system employs orthogonal frequency division multiplexing.
13. The method of claim 1 , wherein the primary carrier includes a downlink carrier and an uplink carrier.
14. The apparatus of claim 7 , wherein the primary carrier includes a downlink carrier and an uplink carrier.
