Abstract: The present specification provides a method for performing paging in a wireless communication system. The method comprises the steps of: confirming whether or not a first paging message transmitted by means of a base station is received during a paging period; if the first paging message has not been received during the paging period, receiving one or more synchronization signals from one or more base stations; detecting a PCID and a PCID group of the one or more base stations on the basis of the one or more synchronization signals; by means of the detected PCID or PCID group, identifying one or more subframes for receiving a second paging message; receiving the second paging message from the one or more identified subframes; and sequentially decoding the second paging message which has been received from the one or more subframes.

Abstract: The present document is for a wireless communication using multiple antenna units based on new virtual user equipment (virtual UE) concept. A user equipment (UE), according to the present invention, receives service from a network in a wireless communication system by registering multiple antenna units of the UE as two or more virtual UEs with a first network entity of the network, wherein the first network entity is a network node for physical radio link control; and receiving the service from the network by the two or more virtual UEs. The two or more virtual UEs of the UE are recognized as one UE by network entities of the network other than the first network entity.

Abstract: Provided are a method and an apparatus for transmitting uplink data in a wireless communication system. Specifically, a first terminal transmits a random access preamble for requesting a connectionless transmission. The first terminal receives a random access response comprising scheduling information of the uplink data. The first terminal transmits uplink data and a reference signal from a first resource configured on the basis of scheduling information of the uplink data and information indicating the CP length of the reference signal. The CP length of the reference signal can be configured to be identical to the CP length of the random access preamble. The first resource can correspond to a resource utilized by both the first terminal and second terminal.

Abstract: The present document is for a wireless communication with reduced internal signaling burden in the distributed antenna system (DAS). In the proposed method, a user equipment (UE) receives a decoding unit, from the network, by multiple distributed unit (DUs) distributed within the UE, and decodes the decoding unit, at each of the multiple DUs. Each of the multiple DUs reports first information on the decoding result to a central unit (CU) controlling the multiple DUs, and the CU determines decoded bit values of the decoding unit based on the first information acquired from each of the multiple DUs.
