Abstract: The present specification proposes a new procedure of signal transmission or reception between STAs in a case of sensing measurement initiated by an STA rather than an AP. According to an embodiment of the present specification, proposed is a sensing measurement procedure performed by an AP in response to transmission of a sensing initiation frame to the AP by an STA rather than the AP. According to another embodiment of the present specification, according to an embodiment of the present specification, proposed is a procedure in which an STA rather than an AP transmits a sensing initiation frame to the AP, and then the AP requests respondent STAs to transmit NDP frames. According to yet another embodiment of the present specification, proposed is a method for configuring a frame transmitted or received in the above procedures.

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: In a wireless local area network (LAN) system, a transmitting station (STA) may transmit a peer-to-peer (P2P) transmission request frame to an access point (AP). The transmitting STA may receive a P2P transmission response frame from the AP. The transmitting STA may receive a trigger frame from the AP. The trigger frame may include information related to whether same is for an uplink, P2P transmission or both an uplink and P2P transmission. The transmitting STA may transmit data to a receiving STA. The transmitting STA and the receiving STA may be non-AP STAs. The transmitting STA may transmit a null data packet announcement (NDPA) frame and a null data packet (NDP) frame to the receiving STA. The transmitting STA may receive, from the receiving STA, a feedback frame including state information for the channel between the transmitting STA and the receiving STA.

Abstract: A method performed in a wireless local area network (LAN) system according to various embodiments is associated with a first station (STA) supporting multi-links comprising first and second links. A control field associated with an operating mode (OM) of the first STA can be associated with the on-off of the first link and/or the second link. The first and second links can each be a channel for various bandwidths defined in, for example, 2.4 GHz band, 5 GHz band and 6 GHz band. The first and second links can belong to the same or different bands. On-off information relating to each link can be formed on the basis of information such as an index or a control field bitmap associated with the operating mode.

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.
