Abstract
Methods and apparatus are described for a User Equipment (UE) to determine a set of resources available for transmitting an acknowledgement signal in an UpLink (UL) Component Carrier (CC) in response to reception of multiple DownLink (DL) Scheduling Assignments (SAs) transmitted from a base station with each DL SA being associated with a respective DL CC. The UL CC and a first DL CC establish a communication link when the UE is configured for communication over a single UL CC and a single DL CC.
Claims18
A method of a User Equipment (UE), comprising:
- receiving Downlink Scheduling Assignment (DL SA) and data from a Base Station (BS), the DL SA including a Transmission Power Control (TPC) and a Downlink Assignment Index (DM);
- determining a resource for an acknowledgement signal based on a value of the TPC and a value of the DAI;
- and
- transmitting, to the BS, the acknowledgment signal via the determined resource.
A User Equipment (UE), comprising:
- a receiver configured to receive Downlink Scheduling Assignment (DL SA) and data from a Base Station (BS), the DL SA including a Transmission Power Control (TPC) and a Downlink Assignment Index (DAI);
- a controller configured to determine a resource for an acknowledgement signal based on a value of the TPC and a value of the DAI;
- and
- a transmitter configured to transmit, to the BS, the acknowledgment signal via the determined resource.
A Base Station (BS), comprising:
- a transmitter configured to transmit a Downlink Scheduling Assignment (DL SA) and data to a User Equipment (UE), the DL SA including a Transmission Power Control (TPC) and a Downlink Assignment Index (DAI);
- and
- a receiver configured to receive, from the UE, an acknowledgment signal via a resource,
- wherein the resource is determined, by the UE, for the acknowledgement signal based on a value of the TPC and a value of the DAI.
