Abstract: A method for uplink transmission in a wireless communication system. A user equipment (UE) determines whether to transmit or drop a sounding reference signal (SRS) on a last symbol in a ith subframe. The SRS is dropped if multiple timing advance groups (TAGs) are configured, if a portion of the last symbol of the ith subframe for transmitting the SRS toward a first serving cell in a first TAG is overlapped with an (i+1)th subframe for transmitting an uplink channel toward a second serving cell in a second TAG and if a total power of the SRS and the uplink channel exceeds a maximum value on the overlapped portion of the last symbol.

Abstract: A method and apparatus are provided for configuring subframes in a wireless communication system. A user equipment (UE) receives an uplink-downlink configuration from a base station. The uplink-downlink configuration indicates each of a plurality of subframes in a frame to any one of a downlink subframe, a special subframe and an uplink subframe. The special subframe includes a downlink pilot time slot (DwPTS), a guard period (GP) and an uplink pilot time slot (UpPTS). The UE receives frame configuration information from the base station and configures each of the plurality of subframes in the frame to any one of a downlink subframe, a special subframe and an uplink subframe based on the uplink-downlink configuration and the frame configuration information. The UE communicates with the base station using the configured subframes.

Abstract: A method for transmitting channel status information in a wireless communication system. A user equipment (UE) transmits first channel information indicating a set of precoding matrices to a base station (BS) periodically, and transmits second channel information indicating one precoding matrix included in the set of precoding matrices to the BS periodically. The second channel information transmitted in a specific subframe is determined based on first channel information that has most recently been transmitted before the specific subframe. Additionally, the UE calculates a channel quality indicator (CQI) transmitted in the specific subframe based on one precoding matrix specified by the first channel information that has most recently been transmitted before the specific subframe and by the second channel information determined based on the first channel information that has most recently been transmitted before the specific subframe.

Abstract: A method for transmitting uplink control information by a communication apparatus configured with a plurality of cells including a Primary Cell (PCell) and a Secondary Cell (SCell) in a wireless communication system. Only one Physical Downlink Shared Channel (PDSCH) is received on the PCell among the plurality of cells in a first subframe. Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information about the PDSCH is transmitted through a Physical Uplink Control Channel (PUCCH) in a second subframe configured for Scheduling Request (SR) transmission. For a positive SR in the second subframe, the HARQ-ACK information is transmitted using a SR PUCCH resource. For a negative SR in the second subframe, the HARQ-ACK information is transmitted using a HARQ-ACK PUCCH resource different from the SR PUCCH resource.

Abstract: A method, performed by a user equipment (UE), is provided for uplink transmission. The UE determines transmission power of a sounding reference signal (SRS) toward a first cell belonging to a first timing advance group (TAG) and a physical uplink shared channel (PUSCH) toward a second cell belonging to a second TAG and whether to transmit both the PUSCH and the SRS, or drop the SRS. The UE transmits only the PUSCH but drops the SRS when the UE determines that the plurality of TAGs including the first and second TAGs are configured, that at least one symbol of a first subframe which is used to transmit the SRS toward the second cell of the second TAG is overlapped with a second subframe on which the PUSCH is transmitted toward the first cell of the first TAG and that a total uplink transmission power exceeds a maximum value.

Abstract: A method of configuring a positive acknowledgement (ACK) or negative acknowledgement (NACK) in a wireless communication system based on time division duplex (TDD) in which M, M=4, downlink subframes are associated with an uplink subframe. The method is performed by a user equipment receiving a physical downlink shared channel (PDSCH) and a physical downlink control channel (PDCCH). The user equipment receives at least one downlink transport block in the M downlink subframes from a first serving cell. The user equipment determines ACK/NACK states {HARQ-ACK(1), HARQ-ACK(2), HARQ-ACK(3), HARQ-ACK(4)} for the first serving cell. The use equipment determines an ACK/NACK response based on the ACK/NACK states.
