Abstract: Methods and apparatus are provided for the transmission of physical downlink control signaling. In one method, a User Equipment (UE) receives information associated with a physical resource block (PRB) for enhanced physical downlink control channel (EPDCCH) from a base station. Based on either first information received on physical control format indicator channel (PCFICH) or second information received on higher layer signaling, the UE determines a starting orthogonal frequency division multiple (OFDM) symbol on which EPDCCH transmission starts. The UE receives control information on the EPDDCH based on the information associated with the PRB and the determined starting OFDM symbol.

Abstract: Methods and apparatuses for a User Equipment (UE) to receive signaling of UE-common Downlink Control Information (DCI) in a set of Physical Resource Blocks (PRBs) over a Transmission Time Interval (TTI) are provided. The UE demodulates UE-common DCI using a Reference Signal (RS) that is scrambled by a UE-common scrambling sequence. The UE may assume that RS having a same precoding is transmitted in the set of PRBs over different TTIs. The UE may determine the scrambling sequence implicitly from an identity of a point transmitting the UE-common DCI or explicitly by higher layer signaling. The UE may determine the PRBs of UE-common DCI transmission by broadcast signaling or by higher layer signaling.

Abstract: Methods and apparatuses are provided for wireless communications. Configuration information including a resource start offset and information for a transmission type of an enhanced physical downlink control channel (EPDCCH) are received. Downlink control information (DCI), transmitted using at least one antenna port of a base station on the EPDCCH using at least one of control channel elements (CCEs), are received. A resource of a physical uplink control channel (PUCCH) is determined based on a first CCE of the at least one of CCEs, information in the DCI, and the resource start offset in the configuration information if the transmission type of the EPDCCH is distributed transmission. A hybrid automatic repeat request acknowledgement (HARQ-ACK) signal is transmitted on the resource to the base station.

Abstract: Methods are described for a Node B to transmit and for a User Equipment (UE) to receive ACKnowledgement (ACK) information associated with the use of Hybrid Automatic Repeat reQuest (HARQ), also known as HARQ-ACK signaling, in a communication system that includes multiple downlink component carriers or multiple uplink component carriers. An HARQ-ACK signal to a UE is in response to a data packet transmission from the UE and may consist of 2 information bits when the UE has 2 or more transmitter antennas. The HARQ-ACK signal is always located in the same downlink component carrier as the scheduling assignment resulting to the data packet transmission from the UE.
