    Abstract: Disclosed is an asynchronous multiple access method and device for a low latency service. The asynchronous multiple access method for low latency service may include the steps of: grouping, by an eNB, each of a plurality of UEs into one UE group among a plurality of UE groups in consideration of each of a plurality of propagation delays of each of the plurality of UEs; receiving, by the eNB, each of a plurality of pieces of uplink data transmitted by each of the plurality of UE groups on each of a plurality of wireless resources allocated for each of the plurality of UE groups at an internal access timing; and transmitting, by the eNB to each of the plurality of UE groups, each of a plurality of ACKs/NACKs signals in response to each of a plurality of uplink frames, wherein the internal access timing can be periodically defined in a symbol unit for the synchronization of transmitting times of the plurality of pieces of uplink data.

    Abstract: The present disclosure is an embodiment of a method for operating a terminal, and the method for operating a terminal in a wireless communication system includes requesting, by the terminal, reference signal (RS) group-related configuration information to a base station, receiving RS group-related configuration information from the base station, learning a first parameter related to a meta-learning learning model based on the RS group-related configuration information, and receiving, by the terminal, a RS from the base station or transmitting a RS to the base station based on the first parameter. The RS group-related configuration information includes pattern information, an identifier and a weight value of at least one of a demodulation-reference signal (DM-RS), a phase-tracking reference signal (PTRS), a channel status information-reference signal (CSI-RS), a positioning reference signal (PRS), a synchronization signal block (SSB), a sounding reference signal (SRS), and a meta-learning RS.

    Abstract: A method and a device used in an optical wireless communication (OWC) system are provided. A transmitting terminal transmits a plurality of reference signals to a receiving terminal through each of a plurality of beams. Each of the plurality of beams may have an inhomogeneous polarization beam pattern. The receiving terminal measures signal strength and polarization with respect to the plurality of reference signals. When the receiving terminal transmits feedback information including the measured signal strength information and polarization information to the transmitting terminal, the transmitting terminal may select at least one beam among the plurality of beams on the basis of the feedback information. Alternatively, the receiving terminal may select at least one beam from among the plurality of beams, which corresponds to at least one inhomogeneous polarization beam pattern among a plurality of inhomogeneous polarization beam patterns, on the basis of the measured signal strength and polarization.
