Abstract:
1. A method for a User Equipment (UE) to determine a resource for a transmission of an acknowledgement signal in an Uplink (UL) Component Carrier (CC) in response to a reception by the UE of multiple Scheduling Assignments (SAs), in a communication system wherein the UE receives multiple SAs transmitted by a base station and corresponds to respective multiple Downlink (DL) CCs, wherein each SA consists of Information Elements (IEs) that include a Transmission Power Control (TPC) IE, with each IE having a value represented by binary elements, the method comprising the steps of: using by the UE the TPC IE value in the SA corresponding to a first DL CC, from the multiple DL CCs, for adjusting the transmission power of the acknowledgment signal; using by the UE the TPC IE value in each SA corresponding to each of the remaining DL CCs, from the multiple DL CCs, for determining the resource used for the transmission of the acknowledgment signal; and transmitting the acknowledgement signal.
