Abstract: A method for uplink transmission in a wireless communication system, the method includes determining, by a user equipment (UE), whether the first uplink signal to be transmitted toward a first cell belonging to a first timing advance group (TAG) at an nth subframe overlaps the second uplink signal to be transmitted toward a second cell belonging to a second TAG at an (n+1)st subframe; dropping, by the UE, the first uplink signal at the nth subframe, if a total transmission power including the first and second uplink signals exceeds a maximum transmit power, where n is an integer≥1; and transmitting the second uplink signal without the first uplink signal which is dropped.

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, 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 and device for transmitting an uplink signal in a wireless communication system A user equipment (UE) sets up a sounding reference signal (SRS) configuration for a first serving cell, the SRS configuration including information for an SRS transmission, and determines an SRS subframe in which an SRS and a physical uplink shared channel (PUSCH) for the first serving cell are simultaneously triggered among a plurality of subframes according to the SRS configuration. The SRS subframe includes a plurality of orthogonal frequency division multiplexing (OFDM) symbols. If an SRS transmission on the SRS subframe for the first serving cell is overlapped with an uplink transmission for a second serving cell, determining, by the UE, whether the SRS is actually to be transmitted in the SRS subframe based on a total uplink transmission power.

Abstract: A method and device for transmitting an uplink signal in a wireless communication system is provided. A user equipment transmits a physical uplink shared channel (PUSCH) on a SRS subframe for a first serving cell to a base station if a SRS transmission on the SRS subframe for the first serving cell is overlapped with an uplink transmission for a second serving cell. The PUSCH is transmitted on remaining orthogonal frequency division multiplexing (OFDM) symbols in the SRS subframe except a single OFDM symbol reserved for the SRS transmission regardless of whether a SRS is transmitted on the single OFDM symbol or not.

Abstract: Provided are a method for transmitting an uplink and a wireless device. The wireless device decides a first wireless resource through which a sounding reference signal (SRS) will be transmitted from a first serving cell, and decides a second wireless resource through which an uplink channel will be transmitted from a second service cell. When all or a portion of the first wireless resource and the second wireless resource overlap, and a total transmission power with respect to the SRS and the uplink channel from the overlapping wireless resources exceeds a predetermined maximum transmission power, the wireless device drops the transmission of the SRS and transmits the uplink channel through the second wireless resource from the second service cell.
