Abstract: An example according to the present specification relates to a method for performing low latency communication. A transmission STA and a reception STA may exchange a low latency communication request frame and a low latency communication response frame. The low latency communication request frame may include first information for performing the low latency communication. The first information may include at least one among information for requesting parameters for the low latency communication and information about traffic. In addition, the low latency communication response frame may include second information for performing the low latency communication. The second information may include information about the parameters for the low latency communication. The reception STA and the transmission STA may perform the low latency communication with the transmission STA on the basis of the first information and the second information.

Abstract: Disclosed herein is a method for transmitting a wake-up signal in a wireless communication system supporting a wake-up radio (WUR) operation. The method performed by a network entity comprises transmitting a first wake-up signal for waking up a specific terminal to a specific access point (AP); transmitting a second wake-up signal to all APs within the coverage of the network entity if a response for the first wake-up signal is not received before a first timer expires; and transmitting, to a base station, a response message including control information indicating whether the specific terminal exists.

Abstract: Disclosed is a method for supporting the handover of a drone in a wireless communication system. The method is performed by the drone and includes measuring signal quality of one or more neighboring eNBs using one or more reference signals (RSs) transmitted by the one or more neighboring eNBs; configuring a candidate set comprising at least one candidate eNB related to the handover based on the measured signal quality, wherein a signal quality value measured with respect to the at least one candidate eNB is greater than a predetermined threshold; comparing the signal quality value of the at least one candidate eNB with a signal quality value of a serving eNB; and transmitting a first message to request the handover to the serving eNB if the signal quality value of the at least one candidate eNB is better than the signal quality value of the serving eNB for a specific period.
