Abstract: Disclosed are a method and an apparatus for controlling distributed transmission power in device-to-device (D2D) communication. The D2D devices individually control their transmission power for the D2D communication link. In addition, a first terminal calculates the transmission power based on the measured channel gain and interference-plus-noise level. The first terminal determines optimal transmission power based on the calculated transmission power by the first terminal, and transmits a transmission power change message including the optimal transmission power to a second terminal. Next, the second terminal transmits a D2D signal based on the optimal transmission power.

Abstract: A base station determines whether a reception of each uplink signal transmitted by a plurality of terminals succeeds. The base station generates a response bit map representing whether the reception succeeds. Further, the base station transmits first downlink control information (DCI) including the response bit map to the plurality of terminals through a first downlink control channel.

Abstract: A method of a terminal may comprise: selecting one of a TN base station or NTN base station as a first base station; performing a first access registration procedure between the terminal and a core network through the first base station; identifying whether the core network supports dual-steering, based on a result of the first access registration procedure; in response to identifying that the core network supports dual-steering, performing a second access registration procedure between the terminal and the core network through a second base station other than the first base station among the TN base station or the NTN base station; and in response to a success of the second access registration procedure, performing a multiple access (MA) protocol data unit (PDU) session establishment procedure according to dual-steering through the first base station.

Abstract: A D2D (Device-to-Device) discovery method is provided which enables a first terminal within a first cell to discover a second terminal within a second cell without relay of a base station. The first terminal receives, from a first base station of the first cell, information about a first resource for D2D discovery through a SIB (System Information Block) or RRC (Radio Resource Control) message. The first terminal transmits a D2D discovery signal using the first resource.

Abstract: A base station infers a random access failure rate depending on a random access collision of terminals performing random access and controls a random access opportunity of a terminal that fails the random access by using the random access failure rate of each terminal. Also, information for the controlled random access opportunity is transmitted to the terminal that fails the random access.

Abstract: A D2D (Device-to-Device) communication method is provided which enables a first terminal of a first group to directly communicate with other terminals of the first group without relay of a base station. The first terminal receives first data from a second terminal. The first terminal determines whether the first data is destined for the first group by using a group identifier of the first data. When the first data is destined for the first group, the first terminal identifies at least one first RLC entity, among multiple RLC (Radio Link Control) entities, that corresponds to the second terminal by using the source terminal identifier of the first data.
