    Abstract: Methods and apparatuses are described for a Node B to transmit Reference Signals (RS) from multiple antennas to enable User Equipments (UEs) to perform demodulation of received information signals and to estimate Channel Quality Indication (CQI) metrics. To minimize overhead and enable backward compatible operation with legacy systems, RS from a first set of Node B antennas are transmitted in every transmission time interval and substantially over the whole operating BandWidth (BW). RS from a second set of Node B antennas serving for CQI estimation are periodically transmitted, substantially over the whole operating BW, with transmission period informed to UEs through broadcast signaling by the Node B and starting transmission sub-frame determined from the identity of the cell served by the Node B. RS from the second set of antennas, and new RS from the first set of antennas, serving for demodulation of information signals have substantially the same BW as the information signals which can be smaller than the operating BW.

    Abstract: Disclosed is a method for wireless communication, including identifying first offset information and second offset information, identifying a size of uplink data for a user equipment, and transmitting the uplink data with at least one of acknowledgement/non-acknowledgment (ACK/NACK) information and channel quality indicator (CQI) information on a physical uplink shared channel, wherein a number of symbols for the ACK/NACK information is determined based on the first offset information and the size of uplink data, and a number of symbols for the CQI information is determined based on the second offset information and the size of uplink data.

    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 transmitted. Downlink control information (DCI) is transmitted to a user equipment (UE) using at least one antenna port of a base station on the EPDCCH using at least one of control channel elements (CCEs). A resource of a physical uplink control channel (PUCCH) is determined based on a first CCE of the at least one of CCE, 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 received on the determined resource.
