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. Information is received for transmission of the acknowledgement signal in an operating bandwidth. A resource block (RB) is determined for transmission of the acknowledgement signal, based on the information. The acknowledge signal is transmitted on the determined RB.
1. A method for transmitting acknowledgement signal by a user equipment (UE) in a wireless communication system, the method comprising:
receiving information associated with transmission of a periodic channel quality indication (CQI) signal in an operating bandwidth;
transmitting a first acknowledgement signal by using a first frequency resource allocated to the UE, when the UE transmits a dynamic acknowledgement signal in response to reception of a downlink data signal, an resource block (RB) allocated for the first acknowledgement signal being determined based on the received information; and
transmitting a second acknowledgement signal by using a second frequency resource allocated to the UE, when the UE transmits a periodic acknowledgement signal in response to reception of a downlink data signal, the second frequency resource being allocated between the first frequency resource and a third frequency resource allocated for the periodic CQI signal.
2. The method of claim 1 , wherein the third frequency resource for the periodic CQI signal is allocated on each side of the operating bandwidth.
3. The method of claim 1 , wherein the first and second frequency resources are allocated between the third frequency resource allocated for the periodic CQI signal and a fourth frequency resource allocated for a data signal.
4. The method of claim 1 , wherein:
the information comprises an index associated with a plurality of resource blocks (RBs) for the periodic CQI signal; and
the RB allocated for the first acknowledgement signal is determined based on a first RB corresponding to the index.
5. The method of claim 4 , wherein the index is used as an offset value for determining the RB in the operating bandwidth.
6. A user equipment (UE) for transmitting an acknowledgement signal in a wireless communication system, the UE comprising:
a transceiver; and
a processor coupled with the transceiver and configured to:
receive information associated with transmission of a periodic channel quality indication (CQI) signal in an operating bandwidth,
transmit a first acknowledgement signal by using a first frequency resource allocated to the UE, if the UE transmits a dynamic acknowledgement signal in response to reception of a downlink data signal, an resource block (RB) allocated for the first acknowledgement signal being determined based on the received information, and
transmit a second acknowledgement signal by using a second frequency resource allocated to the UE, if the UE transmits a periodic acknowledgement signal in response to reception of a downlink data signal, the second frequency resource being allocated between the first frequency resource and a third frequency resource allocated for the periodic CQI signal.
7. The UE of claim 6 , wherein the third frequency resource for the periodic CQI signal is allocated on each side of the operating bandwidth.
8. The UE of claim 6 , wherein the first and second frequency resources are allocated between the third frequency resource allocated for the periodic CQI signal and a fourth frequency resource allocated for a data signal.
9. The UE of claim 6 , wherein:
the information comprises an index associated with a plurality of resource blocks (RBs) for the periodic CQI signal; and
the RB allocated for the first acknowledgement signal is determined based on a first RB corresponding to the index.
10. The UE of claim 9 , wherein the index is used as an offset value for determining the RB in the operating bandwidth.
