    Abstract: Methods and apparatuses are provided for sounding reference signal (SRS) transmission. A plurality of parameter sets are received for an aperiodic SRS transmission. First downlink control information is received comprising an SRS request field with a first value indicating one of the plurality of parameter sets. Second downlink control information is received comprising an SRS request field with a second value indicating one of the plurality of parameter sets. A transmission of an aperiodic SRS is determined based on whether the first value is identical to the second value.

    Abstract: Methods and apparatus are described for User Equipment (UE) to concurrently transmit Uplink Control Information (UCI) and data information to a Node B. The Node B can configure the UE to transmit UCI together with data information in a Physical Uplink Shared CHannel (PUSCH) or separate from data information in a Physical Uplink Control CHannel (PUCCH). The UE may also determine whether to transmit UCI together with data information in the PUSCH or separate from data information in the PUCCH based on criteria involving a ratio of PUSCH resources for UCI transmission over the total PUSCH resources, a Modulation and Coding Scheme (MCS) for the data information, an absolute power difference between PUCCH and PUSCH transmissions, whether the PUSCH transmission uses frequency hopping, and/or whether spatial multiplexing is used for the data transmission.

    Abstract: Methods and apparatuses are provided for transmitting a set of acknowledgement (ACK) bits, by a user equipment (UE). A first subset of ACK bits is transmitted. A second subset of ACK bits is transmitted. The first subset of ACK bits is a response to a reception of one or more scheduling assignments (SAs) for a first cell group, and the second subset of ACK bits is a response to a reception of one or more SAs for a second cell group. The first subset of ACK bits is different from the second subset of ACK bits. A union of the first subset of ACK bits and the second subset of ACK bits is the set of ACK bits that the UE transmits in a subframe.

    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.
