Uplink control signal design for wireless system
View Patent ↗A method for an SS to perform network entry in a multi-carrier wireless environment that has a primary carrier and at least one secondary carrier associated with a BS, the method comprising: a. sensing a carrier in an area serviced by the BS; b. determining if the carrier is a primary carrier or a secondary carrier; and c. performing the network entry if the determining establishes that the sensed carrier is a primary carrier and not a secondary carrier.
1. A method in a mobile station, the method comprising:
establishing communication in a multi-carrier wireless communication system using a primary carrier;
receiving a first downlink control signaling via the primary carrier, the first downlink control signaling assigning at least one secondary carrier, the secondary carrier being different from the primary carrier;
transmitting a channel quality indication via the primary carrier using an uplink control channel, the channel quality indication corresponding to the secondary carrier;
receiving timing information corresponding to the primary carrier; and
transmitting 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.
3. The method of claim 1 , wherein the primary carrier contains a synchronization channel.
4. The method of claim 1 , further comprising receiving a second control signaling via the primary carrier, the second control signaling changing the primary carrier.
5. The method of claim 4 , wherein both primary carriers are associated with the same base station.
6. The method of claim 1 , further comprising receiving a message assigning the control channel.
7. The method of claim 1 , wherein the multi-carrier wireless communication system employs orthogonal frequency division multiplexing.
8. An apparatus comprising:
a transceiver; and
a processor configured to:
establish communication in a multi-carrier wireless communication system using a primary carrier;
receive a first downlink control signaling via the primary carrier, the first downlink control signaling assigning at least one secondary carrier, the secondary carrier being different from the primary carrier;
transmit a channel quality indication via the primary carrier using an uplink control channel, the channel quality indication corresponding to the secondary carrier;
receive timing information corresponding to the primary carrier; and
transmit uplink data via the secondary carrier, the timing of the uplink transmission based on the timing information corresponding to the primary carrier.
9. The apparatus of claim 8 , wherein the primary carrier corresponds to the carrier used for network entry.
10. The apparatus of claim 8 , wherein the primary carrier contains a synchronization channel.
11. The apparatus of claim 8 , the processor further configured to receive a second control signaling via the primary carrier, the second control signaling changing the primary carrier.
12. The apparatus of claim 11 , wherein both primary carriers are associated with the same base station.
13. The apparatus of claim 8 , the processor further configured to receive a message assigning the control channel.
14. The apparatus of claim 8 , wherein the multi-carrier wireless communication system employs orthogonal frequency division multiplexing.
15. A non-transitory machine-readable medium with a set of instructions stored thereon, which when executed, cause a processor to perform operations comprising:
establishing communication in a multi-carrier wireless communication system using a primary carrier;
receiving a first downlink control signaling via the primary carrier, the first downlink control signaling assigning at least one secondary carrier, the secondary carrier being different from the primary carrier;
transmitting a channel quality indication via the primary carrier using an uplink control channel, the channel quality indication corresponding to the secondary carrier;
receiving timing information corresponding to the primary carrier; and
transmitting uplink data via the secondary carrier, the timing of the uplink transmission based on the timing information corresponding to the primary carrier.
16. The non-transitory machine-readable medium of claim 15 , wherein the primary carrier corresponds to the carrier used for network entry.
17. The non-transitory machine-readable medium of claim 15 , wherein the primary carrier contains a synchronization channel.
18. The non-transitory machine-readable medium of claim 15 , the operations further comprising receiving a second control signaling via the primary carrier, the second control signaling changing the primary carrier.
19. The non-transitory machine-readable medium of claim 18 , wherein both primary carriers are associated with the same base station.
20. The non-transitory machine-readable medium of claim 15 , the operations further comprising receiving a message assigning the control channel.
21. The non-transitory machine-readable medium of claim 15 , wherein the multi-carrier wireless communication system employs orthogonal frequency division multiplexing.
