Abstract: A disclosure of the present specification provides a method for managing uplink quality of service (QoS) by a base station. The method may comprise the steps of: determining whether a timer, driven by a terminal in relation to reflective QoS, has expired; during driving of the timer of the terminal, transmitting multiple packets within a traffic flow, to which the reflective QoS is applied, without setting at least one of a reflective QoS indication (RQI) and a QoS flow ID (QFI) for the multiple packets therewithin; and before expiration of the timer being driven by the terminal, setting at least one of the RQI and the QFI for at least one packet within the traffic flow and transmitting the set packet.

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: Provided are a method and device for transmitting uplink data in a wireless communication. More specifically, a user equipment (UE) receives, from a first base station (BS), cell group information indicating that the first BS and a second BS are included in the same cell group. The UE receives, from the first BS, a first reference signal and assignment information regarding a first semi-persistent scheduling (SPS) resource. The UE transmits, to the second BS, a first uplink signal on the basis of the first SPS resource and the first reference signal.

Abstract: Provided are a method and an apparatus for measuring inter-RU interference in order to perform space division duplex communication in a wireless communication system. Specifically, a terminal acquires first interference information indicating the strength of inter-RU interference after analog interference cancellation, and second interference information indicating the strength of inter-RU interference before analog interference cancellation. The terminal determines whether space division duplex communication can be performed between RUs, by comparing the interference strength indicated by the first interference information with a first threshold. The terminal determines whether inter-RU interference needs to be periodically measured, by comparing the interference strength indicated by the second interference information with a second threshold.
