Abstract
An uplink ACK/NACK signaling method and apparatus in carrier aggregation environment are disclosed. The method for performing a HARQ procedure by a user equipment in a wireless communication system includes receiving one or more control channels carrying downlink scheduling information from a base station (BS), wherein each control channel carries information indicating a total number of control channels transmitted from the BS to the UE, and determining whether the total number of control channels transmitted to the UE is identical to the number of control channels received at the UE.
Claims22
A method for performing a hybrid automatic repeat and request (HARQ) procedure by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving one or more control channels carrying downlink scheduling information from a base station (BS),
- wherein each control channel carries specific information indicating a total number of control channels transmitted from the BS to the UE;
- determining whether the total number of control channels transmitted to the UE is identical to the number of control channels received at the UE;
- and
- transmitting infomation based on whether the total number of control channels transmitted to the UE is identical to the number of control channels received at the UE.
A method for performing a hybrid automatic repeat and request (HARQ) procedure by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving one or more downlink control channels carrying downlink scheduling information from a base station (BS),
- wherein each downlink control channel carries information indicating an order value of each downlink control channel within a plurality of downlink control channels transmitted from the BS to the UE;
- determining whether or not the one or more downlink control channels received from the BS are contiguous in order;
- and
- transmitting information based on whether or not the one or more downlink control channels received from the BS are contiguous in order.
A user equipment (UE) for performing a hybrid automatic repeat and request (HARQ) procedure in a wireless communication system, the user equipment (UE) comprising:
- a processor;
- and
- a memory containing instructions, which when executed, cause the processor to:
- receive one or more control channels carrying downlink scheduling information from a base station (BS),
- wherein each control channel carries specific information indicating a total number of control channels transmitted from the BS to the UE;
- determine whether the total number of control channels transmitted to the UE is identical to the number of control channels received at the UE, and
- transmit information based on whether the total number of control channels transmitted to the UE is identical to the number of control channels received at the UE.
A user equipment (UE) for performing a hybrid automatic repeat and request (HARQ) procedure in a wireless communication system, the user equipment (UE) comprising:
- a processor;
- and
- a memory containing instructions, which when executed, cause the processor to:
- receive one or more downlink control channels carrying downlink scheduling information from a base station (BS),
- wherein each downlink control channel carries information indicating an order value of each downlink control channel within a plurality of downlink control channels transmitted from the BS to the UE;
- and
- determine whether or not the one or more downlink control channels received from the BS are contiguous in order, and
- transmit information based on whether or not the one or more downlink control channels received from the BS are contiguous in order.
