METHOD AND APPARATUS FOR TRANSMITTING SIGNAL IN DEVICE-TO-DEVICE COMMUNICATION

摘要

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.

主权项

1. A method for transmitting an uplink signal of a user equipment (UE) in a wireless communication system, the method comprising:
receiving uplink (UL) grants from a serving base station; and performing the UL grant based-UL transmission in a TTI bundle or device-to-device (D2D) reception/transmission (Rx/Tx) using a configuration for D2D communication and a configuration for transmission time interval (TTI) bundling, wherein, if the UL transmission in the TTI bundle and the D2D Rx/Tx are simultaneously scheduled in a specific TTI, the UL transmission scheduled in the specific TTI is performed in a first available TTI after the specific TTI, and wherein, if two different UL grants based-UL transmissions are simultaneously scheduled in a specific TTI, the UL transmission indicated by the later received UL grant of the two different UL grants is dropped.
