Abstract: A device of a user equipment (UE) includes at least one transceiver and at least one processor coupled to the at least one transceiver. The at least one processor is configured to perform a compensation for doppler shift based on ephemeris information for non-terrestrial network (NTN) device and position information of the UE. The at least one processor is configured to transmit a message including compensation information to a network node through the NTN device based on the compensation. The compensation information indicates at least one of a frequency shift value according to the doppler shift or a doppler shift change rate indicating a change rate of a frequency shift value per unit time. The NTN device includes a satellite that moves based on the ephemeris information.

Abstract: In embodiments, a method performed by a non-terrestrial network (NTN) device includes transmitting a UE capability enquiry message to a user equipment (UE) and receiving a UE capability information message corresponding to the UE capability enquiry message from the UE. The UE capability information includes at least one of information for indicating one of a plurality of types of NTN non-geostationary satellite orbit (NGSO) or information on a maximum number of one or more satellites accessible in the UE.

Abstract: According to embodiments, a method performed by a non-terrestrial network (NTN) device for providing a new radio (NR) access may include generating NTN configuration information, and transmitting a message comprising the generated NTN configuration information to a user equipment (UE) via an NTN payload. The NTN configuration information may include scheduling offset information. The scheduling offset information may be applied to a difference between physical downlink control channel (PDCCH) reception and physical uplink control channel (PUCCH) transmission or a difference between PDCCH reception and physical uplink shared channel (PUSCH) transmission. The scheduling offset information may be indicated by a number of slots, based on subcarrier spacing (SCS) for a frequency range (FR) 2 band of the NR.

Abstract: According to various embodiments, a first user equipment (UE) includes a memory; a transceiver to transmit and receive a wireless signal; and a processor connected with the memory and the transceiver, wherein the processor is configured to determine to perform communication through a sidelink on unlicensed band with a second UE while the first UE is in a state which is out of coverage of a base station, based on the determination, identify pre-configuration information stored in the memory, obtain a priority threshold value for the sidelink on the unlicensed band from the pre-configuration information, and determine, based on the priority threshold value, whether to transmit data through the sidelink on the unlicensed band with the second UE.

Abstract: According to various embodiments, a first user equipment (UE) include a transceiver to transmit and receive a wireless signal; and a processor connected to the transceiver, wherein the processor is configured to receive first side link control information (SCI) from a second UE through a physical side link control channel (PSCCH) configured in unlicensed band, receive a second SCI from the second UE through a physical side link shared channel (PSSCH) determined based on the PSCCH, wherein the first SCI and the second SCI are configured in different formats, based on at least one of the first SCI and the second SCI, identify information for performing side link communication with the second UE in the unlicensed band, and receive, based on the identified information, data from the second UE through a side link communication path between the first UE and the second UE.

Abstract: According to various embodiments, a first user equipment (UE) includes a transceiver to transmit and receive a wireless signal; and a processor connected with the transceiver, wherein the processor is configured to identify a value related to quality of sidelink communication while the first UE performs sidelink communication in licensed band with a second UE, determine to perform a listen before talk (LBT) procedure on a condition that the value related to the quality of the sidelink communication is less than or equal to a reference value, and perform the LBT procedure during performing the sidelink communication in the licensed band.

Abstract: Video streaming from the first external electronic device, such as the vehicle image acquisition device according to various embodiments, may be processed based on a designated state (e.g., a traffic accident) identified by the first external electronic device. For example, when receiving a notification related to a designated state from the first external electronic device, the electronic device may acquire information related to the designated state and then broadcast the obtained information to one or more terminals (e.g., terminal 130 of FIG. 5), through a second external electronic device such as a navigation server. In response to the broadcasting, the terminal may provide information related to the designated state to the user of the terminal. The information may be used to change a navigation path provided by the terminal.
