Abstract
Methods and apparatus are described for a User Equipment (UE) to transmit acknowledgement information together with data information in a Physical Uplink Shared CHannel (PUSCH) or separate from data information in a Physical Uplink Control CHannel (PUCCH). The HARQ-ACK payload for transmission in a PUSCH and the HARQ-ACK signal transmission power for transmission in a PUCCH are derived based on the existence and design of a Downlink Assignment Index (DAI) Information Element (IE) in the Downlink Control Information (DCI) formats scheduling receptions of data Transport Blocks (TBs) by the UE.
