Abstract: The present disclosure relates to a method for transmitting duplicated data units by considering measurement gap in a wireless communication system. In particular, the method includes the steps of: generating a Medium Access Control (MAC) Protocol Data Unit (PDU) containing a MAC Service Data Unit (SDU) associated with a logical channel; and transmitting the MAC PDU based on there being no measurement gap at the time of the transmission, wherein, based on there being the measurement gap at the time of the transmission, a Packet Data Convergence Protocol (PDCP) duplication of a Radio Bearer (RB) related to the logical channel is activated.

Abstract: The present invention relates to a method of transmitting a data unit by a user equipment (UE) belonging to a UE group in a wireless communication system. Especially, the method includes the steps of receiving the data unit from an upper layer; associating first time information with the data unit; transmitting a request message for transmitting the data unit; receiving an uplink grant with second time information related to the UE group in response to the request message; transmitting the data unit with the first time information on the uplink grant based on the first time information not being matched with the second time information, wherein the data unit is discarded based on the first time information being matched with the second time information.

Abstract: The present invention relates to a method for transmitting signals by a transmission end in a wireless communication system. In particular, the method includes the steps of: configuring one Packet Data Convergence Protocol (PDCP) entity, at least one first RLC entity related to the one PDCP entity and at least one second RLC entity related to the one PDCP entity;
determining whether a service data unit (SDU) to be transmitted is a special SDU or not; if the SDU is the special SDU, transmitting the SDU to the at least one first RLC entity; and if the SDU is not the special SDU, transmitting the SDU to the at least one second RLC entity.
