Abstract: A method and apparatus for activation and retransmissions for a pool of resources is provided. A first device autonomously selects a set of resources on a pool of resources for N number of transmissions of a Transport Block (TB) stored in a process. The first device transmits, to the network, a request for a retransmission grant for the process based on i) the N number of transmission being completed and ii) retransmission of the TB being required. The request includes a Hybrid Automatic Repeat request (HARQ) process identifier (ID) associated to the process.

Abstract: A method of operating a Tx user equipment (UE) in a wireless communication system includes transmitting a random access preamble corresponding to a synchronization signal block (SSB) by the Tx UE, receiving a random access response in response to the random access preamble by the Tx UE, establishing a link with a Rx UE by the Tx UE, and transmitting a radio resource control (RRC) message based on sidelink radio link failure (RLF) to a base station (BS) by the Tx UE. The RRC message is related to reporting of the sidelink RLF to the BS, and includes a destination identifier (ID) related to the sidelink RLF.

Abstract: A method and a device for transmitting metadata in a WFD are provided. Particularly, a WFD source forms a WFD frame including a WFD header and metadata. The WFD source transmits, to a WFD sink, a packet stream created by packetizing a metadata stream including the WFD frame. The WFD header includes a metadata structure field and a metadata update indicator. The metadata structure field indicates whether the metadata has a video metadata structure or an audio metadata structure. The metadata update indicator indicates that previous metadata is updated such that all of the previous metadata is replaced with new metadata, or that the previous metadata is incrementally updated together with updated metadata.

Abstract: The present document relates to a method for efficiently performing uplink multi-user transmission in a wireless LAN system and an apparatus therefor. To this end, an access point (AP) may transmit a downlink multi-user frame to a plurality of STAs, receive an uplink frame including an acknowledgement/non-acknowledgement (ACK/NACK) signal for the downlink multi-user frame and an uplink scheduling request signal from at least two STAs among the STAs, transmit a downlink frame including uplink scheduling information to the at least two STAs on the basis of the uplink scheduling request signal, and receive an uplink multi-user frame including data from the at least two STAs in response thereto. Here, an SIG field of the downlink frame preferably comprises an indicator indicating that the downlink frame includes uplink multi-user scheduling information.

Abstract: The present document relates to a wireless communication system and, more specifically, to a method for flexibly supporting resource allocation in a wireless LAN system, and a method and an apparatus for signal transmission using the same. To this end, a first STA configures a radio frame comprising: a signaling (SIG) field including control information; and a data field in which data can be transmitted via a discontinuous channel or a channel having a bandwidth size that is supported by a legacy system. When the first STA transmits the configured radio frame to a second STA, the SIG field preferably comprises: information about a full bandwidth in which data can be transmitted via the data field; and null indicator information indicating a channel region of the full bandwidth that is not used in data transmission, or used channel indicator information indicating a channel region of the full bandwidth that is used in data transmission.
