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.
Abstract translation: 提供了一种D2D（设备到设备）通信方法，其使得第一组的第一终端能够直接与第一组的其他终端通信，而无需基站的中继。 第一终端从第二终端接收第一数据。 第一终端通过使用第一数据的组标识符来确定第一数据是否发往第一组。 当第一数据指定给第一组时，第一终端通过使用第一数据的源终端标识符来标识多个RLC（无线链路控制）实体中对应于第二终端的至少一个第一RLC实体。

Abstract: A first terminal receives a first Timing Advance (TA) value from a base station and includes a second TA value that is obtained based on the first TA value in a Scheduling Assignment (SA) signal. The first terminal transmits the SA signal to a second terminal at downlink (DL) timing for receiving a downlink signal of the base station in cellular communication. When a length of a Cyclic Prefix (CP) that is set for the D2D communication and a length of a CP that is set for the cellular communication are different, the first terminal transmits data of the D2D communication to the second terminal at first timing that is obtained by applying the second TA value to the DL timing.
Abstract translation: 第一终端从基站接收第一定时提前（TA）值，并且包括基于调度分配（SA）信号中的第一TA值获得的第二TA值。 第一终端在下行链路（DL）定时将SA信号发送到第二终端，用于在蜂窝通信中接收基站的下行链路信号。 当针对D2D通信设置的循环前缀（CP）的长度和为蜂窝通信设置的CP的长度不同时，第一终端在第一定时向第二终端发送D2D通信的数据， 通过将第二TA值应用于DL定时来获得。

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: 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.
