Abstract:
The present invention discloses a method for transmitting a discovery message in a wireless communication system and an apparatus for the method. More specifically, a method for transmitting a discovery message in a wireless communication system supporting communication between user equipments (UEs) comprises estimating, by a UE, an energy level over an energy detection interval configured within a discovery resource pool; determining, by the UE, a discovery resource region of the UE on the basis of the estimated energy level; selecting, by the UE, a discovery resource for transmitting a discovery message within the determined discovery resource region; and transmitting, by the UE, the discovery message from the selected discovery resource.
Abstract:
An embodiment of the present invention relates to a method for transmitting or receiving a side link signal by a first terminal in a wireless communication system, the method comprising the steps of: selecting a first resource through which the first terminal will transmit a message; determining a second resource, which is determined dependent on the position of the selected first resource and is to be used for performing feedback; and transmitting feedback information on the message and the second resource, wherein the feedback information is feedback information relating to a broadcast message received through at least a part of the second resource.
Abstract:
This specification provides a method for performing a discovery procedure in a wireless communication system supporting device to device (D2D) communication. The method is performed by first user equipment and includes monitoring a discovery resource region, selecting a discovery resource for transmitting a discovery message in the discovery resource region, and transmitting the discovery message to second user equipment through the selected discovery resource. The selected discovery resource includes a discovery resource having a received energy level corresponding to a threshold value or less or a threshold value or higher.
Abstract:
A method for terminal clustering in a wireless communication system supporting D2D (Device-to-Device) communication and an apparatus supporting the method are disclosed. More specifically, a method for a user equipment (UE) to perform UE clustering in a wireless communication system supporting D2D communication comprises determining an initial preference value, determining an initial preference triplet by performing an AP (Affinity Propagation) method by increasing or decreasing the preference value, updating a preference triplet through a GSS (Golden Section Search) method based on the initial preference triplet, determining a final preference value for minimizing energy consumption of the entire UEs from the updated preference triplet; and determining a head UE and member UEs belonging to the head UE by performing the AP method by using the final preference value.

Abstract:
One embodiment of the present invention relates to a method for user equipment receiving broadcast feedback information transmitting a message in a wireless communication system, the method for user equipment receiving broadcast feedback information transmitting a message comprising the steps of: broadcasting a first message from a first resource; receiving, from a plurality of user equipment which have received the broadcast, information relating to resource use of the first resource; determining whether to perform resource reselection from resource use of the first resource received from the plurality of user equipment; and transmitting a second message using a reselected resource when the resource reselection is to be performed, wherein the information relating to resource use is a status value corresponding to the number of user equipment using the first resource.
Abstract:
Disclosed herein are a method and apparatus for transmitting and receiving discovery messages in a wireless communication system. Specifically, a method for transmitting and receiving discovery messages in a wireless communication system supporting communication between user equipments (UEs) includes receiving, by a UE in a Radio Resource Control_IDLE (RRC_IDLE) state, information about an allocated resource for transmitting a discovery message from a network and transmitting, by the UE, the discovery message in the resource for transmitting the discovery message. The resource for transmitting the discovery message may be allocated based on a tracking area in which the device is located.
