Abstract: A method for transmitting an uplink signal of a user equipment (UE) in a wireless communication system includes receiving an uplink (UL) grant from a serving base station and performing UL transmission based on the UL grant or device-to-device (D2D) communication, according to a configuration for D2D communication and a configuration of transmission time interval (TTI) bundling. When bundled UL transmission based on the UL grant and transmission for D2D communication are scheduled in the same TTI, the UL transmission scheduled in the TTI is performed in a first available TTI after the TTI, and, when two bundled UL transmissions according to two different UL grants are scheduled in the same TTI, bundled UL transmission according to the later received UL grant of the two different UL grants is dropped.

Abstract: A method for transmitting an uplink signal at a User Equipment (UE) in a wireless communication system includes receiving, from a Base Station (BS), an uplink scheduling grant for multi-antenna transmission; transmitting the uplink signal precoded using precoding information included in the received uplink scheduling grant to the BS; and retransmitting the uplink signal to the BS according to Acknowledgment/Negative Acknowledgment (ACK/NACK) corresponding to the transmitted uplink signal. The retransmitted uplink signal is precoded using precoding information included in a most recent uplink scheduling grant or a predetermined precoding matrix if an uplink scheduling grant for the retransmission is not received from the BS.

Abstract: Proposed are a method for carrying out wireless communication by a first device, and a device supporting the same. For example, on the basis of an interworking relationship between the first device and a second device not being established, the first device may transmit a first message, and reception of at least one of a second message or a third message may be omitted. For example, the first device may establish the interworking relationship between the first device and the second device. For example, on the basis of the interworking relationship being established, the first device may receive at least any of the second message or the third message.
