Abstract: Provided is a method for transmitting, by a transmitter, a first data having periodicity through a channel of an unlicensed band:
The transmitter adjusts at least one of transmission timing of the first data and clear channel assessment (CCA) timing for the channel to occupy the channel. The transmitter determines whether the channel may be occupied by performing a CCA on the channel at the CCA timing. The transmitter transmits the first data through the channel at the transmission timing of the first data, when it is determined that the channel may be occupied.-

Abstract: In a direct communication between terminals, a terminal transmits a synchronization channel preamble part after transmitting a synchronization channel message part including synchronization information. The terminal receives a dedicated channel including a direct communication packet after transmitting the synchronization channel preamble part. A transition time gap for switching from transmission to reception may be inserted to an end of the synchronization channel preamble part.
Abstract translation: 在终端之间的直接通信中，终端在发送包括同步信息的同步信道消息部分之后发送同步信道前导码部分。 在发送同步信道前导码部分之后，终端接收包括直接通信分组的专用信道。 用于从传输切换到接收的转换时间间隙可以被插入到同步信道前导码部分的末尾。

Abstract: Disclosed herein are a method and an apparatus for transmitting an uplink signal. The method for transmitting an uplink signal includes: transmitting an uplink data in at least one symbol included in a short transmit time interval (sTTI) including 7 symbols or less; and transmitting a demodulation reference signal (DMRS) for the uplink data through an even-numbered subcarrier or an odd-numbered subcarrier in one symbol in which the uplink data is not transmitted, among the symbols included in the sTTI.

Abstract: Provided are a method and an apparatus for requesting uplink persistent scheduling in a mobile communication system. A terminal generates a semi-persistent scheduling (SPS) buffer status report (BSR) including a size of data and further including at least one of an SPS transmission point in time and an SPS period after configuring SPS between the terminal and a base station, and requests SPS allocation while transmitting the SPS BSR to the base station. The size of the data indicates a size of data that are to be transmitted per SPS period.

Abstract: A handover method and a control transfer method are provided. A handover method of performing an inter-cell handover between a first ground station and a second ground station may include setting a first channel to the second ground station, measuring, by an airborne radio station, a second channel and reporting a measurement result to the first ground station, sending, by the first ground station, a handover request to at least one of a ground control station (GCS) or a control and non-payload communication (CNPC) network, determining, by the at least one of the GCS or the CNPC network, whether to perform a handover, and transmitting, by the at least one of the GCS or the CNPC network, a handover instruction to the airborne radio station based on a result of the determining.

Abstract: A terminal executes a random access procedure with a target base station depending on a pre-random access channel (pre-RACH) command in a handover preparation step executed between a source base station currently accessed by the terminal and the target base station when the terminal receives the pre-RACH command from the source base station through layer2 (L2) signaling in the handover preparation step.

Abstract: In a wireless communication system formed of a plurality of nodes, an arbitrary node receives messages broadcasted from neighbor nodes and calculates amounts of changes in receiving times that are differences between receiving times when the messages are currently received and receiving times when the messages are previously received with respect to the neighbor nodes. The node corrects reference time thereof based on the amounts of changes calculated with respect to the neighbor nodes.
