1. A user equipment (UE) including distributed antenna system operating in a wireless communication system, the UE comprising:
a plurality of distributed units including a radio frequency (RF) antenna; and
a central unit configured to control the plural distributed units,
wherein the plural distributed units store final configuration parameter information based on reception of a power sleep mode configured by the central unit, and
wherein, based on reception of a power activation mode configured by the central unit, the plural distributed units use the stored final configuration parameter information based on configuration of a storage parameter use mode and the plural distributed units receive new configuration parameter information based on non-configuration of the storage parameter use mode,
through the plural distributed units, transmitting a physical channel generated by a physical layer of the UE,
wherein the physical channel is transmitted in a resource unit comprised of orthogonal frequency division multiplexing (OFDM) symbols in a time domain and subcarriers in a frequency domain,
wherein the resource unit is selected in a resource pool including a plurality of resource units,
wherein the physical layer is connected to a medium access control (MAC) layer of the UE through a transport channel,
wherein the transport channel is mapped to a logical channel by the MAC layer of the UE, and data belonging to one or different logical channels is multiplexed into data for the transport channel by the MAC layer of the UE,
wherein the MAC layer of the UE is connected to a radio link control (RLC) layer of the UE through the logical channel,
wherein the RLC layer supports three transmission modes including a transparent mode (TM), an unacknowledged mode (UM), and an acknowledged mode (AM).
