Partitioning of frequency resources for transmission of control signals and data signals in SC-FDMA communication systems
A method and apparatus are provided for determining a resource for an acknowledgement signal by a user equipment (UE) in a wireless communication system. A method includes receiving an index associated with a plurality of resource blocks (RBs) for transmission of an uplink control signal in an operating bandwidth; and determining an RB for transmission of the acknowledgement signal, based on the index.
1. A method for determining a resource for an acknowledgement signal by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, by a transceiver of the UE, an index associated with a plurality of resource blocks (RBs) for periodic transmission of a channel quality indication (CQI) signal in an operating bandwidth;
determining, by a controller of the UE, an RB for transmission of the acknowledgement signal, based on the index; and
transmitting, by the transceiver, the acknowledge signal on the determined RB.
2. The method of claim 1 , wherein the RB is determined based on a first RB corresponding to the index, and
wherein the first RB is for transmission of an acknowledgement signal in the operating bandwidth.
3. The method of claim 1 , wherein the CQI signal is transmitted at both sides of the operating bandwidth, and the acknowledgement signal is transmitted in an interior of the operating bandwidth.
4. The method of claim 1 , further comprising transmitting an uplink data signal in response to a scheduling assignment transmitted from the base station to the UE.
5. The method of claim 1 , wherein the index is used as an offset value for determining the RB in the operating bandwidth.
6. A user equipment (UE) in a wireless communication system, the UE comprising:
a transceiver configured to transmit and receive a signal over a network; and
a controller configured to control receiving an index associated with a plurality of resource blocks (RBs) for periodic transmission of a channel quality indication (CQI) signal in an operating bandwidth, determining an RB for transmission of an acknowledgement signal, based on the index, and transmitting the acknowledgement signal on the determined RB.
7. The UE of claim 6 , wherein the RB is determined based on a first RB corresponding to the index, and
wherein the first RB is for transmission of an acknowledgement signal in the operating bandwidth.
8. The UE of claim 6 , wherein the CQI signal is transmitted at both sides of the operating bandwidth, and the acknowledgement signal is transmitted in an interior of the operating bandwidth.
9. The UE of claim 6 , wherein the controller is further configured to control transmitting an uplink data signal in response to a scheduling assignment transmitted from the base station to the UE.
10. The UE of claim 6 , wherein the index is used as an offset value for determining the RB in the operating bandwidth.
11. A method for determining a resource for an acknowledgement signal by a base station in a wireless communication system, the method comprising:
transmitting, by a transceiver of the base station, an index associated with a plurality of resource blocks (RBs) for periodic transmission of a channel quality indication (CQI) signal in an operating bandwidth; and
receiving, by a controller of the base station, the acknowledgement signal on an RB determined based on the index.
12. The method as claimed in claim 11 , wherein the RB is determined based on a first RB corresponding to the index, and
wherein the first RB is for transmission of an acknowledgement signal in the operating bandwidth.
13. The method as claimed in claim 11 , wherein the CQI signal is transmitted at both sides of the operating bandwidth, and the acknowledgement signal is transmitted in an interior of the operating bandwidth.
14. The method of claim 11 , further comprising receiving an uplink data signal in response to a scheduling assignment transmitted from the base station to the UE.
15. The method of claim 11 , wherein the index is used as an offset value for determining the RB in the operating bandwidth.
16. A base station in a wireless communication system, the base station comprising:
a transceiver configured to transmit and receive a signal over a network; and
a controller configured to control transmitting an index associated with a plurality of resource blocks (RBs) for periodic transmission of a channel quality indication (CQI) signal in an operating bandwidth, and receiving the acknowledgement signal on an RB determined based on the index.
17. The base station of claim 16 , wherein the RB is determined based on a first RB corresponding to the index, and
wherein the first RB is for transmission of an acknowledgement signal in the operating bandwidth.
18. The base station of claim 16 , wherein the CQI signal is transmitted at both sides of the operating bandwidth, and the acknowledgement signal is transmitted in an interior of the operating bandwidth.
19. The base station of claim 16 , wherein the controller is further configured to control receiving an uplink data signal in response to a scheduling assignment transmitted from the base station to the UE.
20. The base station of claim 16 , wherein the index is used as an offset value for determining the RB in the operating bandwidth.
