Abstract: A user equipment (UE) is provided. The UE supports D2D wireless communication and includes a communication module configured to communicate with at least one different UE, a non-transitory computer readable memory storage configured to store instructions, and at least one processor electrically connected to the communication module and the memory storage. The instructions, when executed by the UE, cause the processor to check whether an available first synchronization signal is detected, determine whether to operate as a first synchronization reference UE based on whether the first synchronization signal is detected, and transmit first system information comprising an intensity of transmission power and a second synchronization signal comprising a first synchronization identifier if the UE is determined to operate as the first synchronization reference UE.

Abstract: An electronic device may include: a communication processor; and an application processor configured to transmit data to be transmitted through first cellular communication and/or second cellular communication to the communication processor, wherein the communication processor includes: a PDCP configured to support a split bearer for transmitting split data; a first RLC configured to split data received from the PDCP; and a second RLC configured to split data received from the PDCP, wherein the PDCP is configured to split data received from the application processor into data units having a preset size, identify a data processing rate of the first RLC and a data processing rate of the second RLC, and distribute the data units to the first RLC and the second RLC, based on the data processing rate of the first RLC and the data processing rate of the second RLC.
