METHOD AND APPARATUS FOR ESTABLISHING RESOURCE POOL FOR SCHEDULING ASSIGNMENT SIGNAL OF DIRECT DEVICE-TO-DEVICE COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method of transmitting scheduling assignment (SA) for device-to-device (D2D) communication by a user equipment (UE) in a wireless communication system, the method comprising:
- determining whether data to be transmitted is present using the D2D communication;
determining whether the SA is transmitted according to a resource allocation mode for the D2D communication when the data is not present; and
transmitting first SA when the resource allocation mode is a first mode,wherein the resource allocation mode comprises the first mode in which resource for the D2D communication is allocated by a base station and a second mode in which resource for the D2D communication is allocated according to arbitrary selection of the UE

Abstract
Disclosed in the present application is a method for a terminal transmitting a scheduling assignment (SA) for direct device-to-device communication in a wireless communication system. More specifically, the method comprises the steps of: determining whether data to be transmitted using the direct device-to-device communication is present; determining whether to transmit the SA according to a resource allocation mode for the direct device-to-device communication, when the data is not present; and transmitting a first SA when the resource allocation mode is a first mode, wherein the resource allocation mode includes the first mode in which a resource for the direct device-to-device communication is allocated by a base station, and a second mode in which a resource for the direct device-to-device communication is allocated through a random selection by the terminal.

8. A method of transmitting scheduling assignment (SA) for device-to-device (D2D) communication by a user equipment (UE) in a wireless communication system, the method comprising:
-
determining whether SA is transmitted in a previous SA period; determining whether resource for a data channel in a current SA period is changed when the SA is transmitted in the previous SA period; and transmitting the SA using resource of a first SA resource pool when the resource for the data channel is not changed, wherein, when the SA is not transmitted or the resource for the data channel is changed in the previous SA period, the SA is transmitted using resource of a second SA resource pool. - View Dependent Claims (9, 10, 11, 12, 13)
