Abstract:
Provided are a synchronization signal transmission state reporting method performed by a terminal in a wireless communication system and a terminal using the method. The method comprises: evaluating an event related to the synchronization signal transmission state by the terminal; and when the event is satisfied, transmitting a report for the synchronization signal transmission state.
Abstract:
Provided are a device-to-device (D2D) operation method performed by a terminal in a wireless communication system and a terminal using the method. The method comprises: receiving D2D configuration information from a network, the D2D configuration information indicating a resource that can be used in the D2D operation within coverage of the network; and when a transmitting condition is satisfied, transmitting a D2D message to a second terminal, the D2D message including resource information indicating a resource that can be used in the D2D operation.
Abstract:
A method for device-to-device (D2D) operation performed by a terminal in a wireless communication system, and a terminal using the method are provided. The method comprises: receiving system information including reception resource pool information; and receiving a D2D signal by using resources indicated by the reception resource pool information, wherein the reception resource pool information indicates resources for which receiving the D2D signal is allowed during a radio resource control (RRC) idle state and an RRC connected state.
Abstract:
Provided are a device-to-device (D2D) operation method performed by a terminal in a radio communication system and an apparatus using the method. The method detects a synchronization signal transmitted by a first network node and transmits a report for the detected synchronization signal to a second network node.
Abstract:
A method and apparatus for performing multimedia broadcast multicast service (MBMS) minimization of drive test (MDT) in a wireless communication system is provided. A user equipment (UE) receives a MBMS-MDT timer configuration from a network. A MBMS-MDT timer is newly defined for the MBMS-MDT. The UE starts the MBMS-MDT timer based on the received MBMS-MDT timer configuration when a specific condition, which relates to degradation of quality of MBMS, is met, and while the MBMS-MDT timer is running, the UE performs the MBMS-MDT.
Abstract:
A method and apparatus for performing a random access procedure in a wireless communication system is provided. In one embodiment, a user equipment (UE) determines a required amount of repetitions for uplink transmissions during a random access procedure, and performs repetitions for uplink transmissions based on the determined required amount of repetitions for uplink transmissions. The uplink transmissions may include transmission of preambles which are grouped. In another embodiment, a UE configures a communication windows for lost-cost machine-type communication (MTC) UE, and performs a random access procedure through the configured communication window.
Abstract:
Disclosed are a method of selectively transmitting MBMS level information and an apparatus thereof. A method of transmitting MBMS service level information in a wireless communication system for supporting a Multimedia Broadcast/Multicast Service (MBMS), includes: determining, by User Equipment (UE), whether a received or reception interested MBMS is an MBSB necessary to be reported to a network; and transmitting, by the UE, service level information on the received or reception interested MBMS to the network through a MBMS interest indication message when the MBMS which is received or having interest in reception is the MBMS necessary to be reported to the network.
Abstract:
A method and apparatus for transmitting device-to-device (D2D) related information in a wireless communication system is provided. A user equipment (UE) transmits a D2D-related identifier (ID) to a network during a radio resource control (RRC) connection establishment procedure, and transmits D2D-related group information to the network.
Abstract:
Provided are a method for transmitting/receiving discovery signals in a wireless communication system and user equipment for supporting same. The method comprises the steps of: receiving a discovery request signal from user equipment; and determining whether or not to transmit a discovery response signal in response to the discovery request signal on the basis of the determination of the validity of proximity of the user equipment.
Abstract:
Provided are a method for device to device (D2D) communication performed by terminals in a wireless communication system, and devices therefor. The method is characterized by: determining whether or not a first signal for D2D communication with another terminal and a second signal for communication with a base station collide at the same transmission time; and transmitting only the second signal at the transmission time if the first signal and the second signal collide.
