Scheme for D2D communication using priority
First Claim
1. A communication method of a device to device (D2D) user equipment (UE) in a cellular system supporting a communication frame structure including one or more subframes used for a D2D communication of the D2D UE, the method comprising:
- identifying an alarm region located within a first subframe, wherein the alarm region indicates whether a communication signal of another D2D UE having a priority is included in the first subframe or a second subframe related to the first subframe; and
transmitting a communication signal of the UE through one of the second subframe and a third subframe related to the second subframe,wherein the first subframe and one of the second subframe or the third subframe, are used in the D2D communication of the UE, andwherein the identifying of the alarm region further comprises checking energy levels of entire alarm regions.

Abstract
A communication method of a device to device (D2D) user equipment (UE) in a cellular system supporting a communication frame structure including one or more subframes used for a communication of the D2D UE is provided. The method includes reading an alarm region located within a first subframe, wherein the alarm region indicates whether a communication signal having a priority is included in the first subframe or a second subframe related to the first subframe, and transmitting the communication signal through one of the second subframe and a third subframe related to the second subframe, based on information read from the alarm region.

11. An user equipment (UE) performing a communication in a cellular system supporting a communication frame structure including one or more subframes used for a device to device (D2D) communication of the UE, the UE comprising:
-
a transceiver configured to transmit and receive a communication frame; and a controller configured to; identify an alarm region located within a first subframe, the alarm region indicating whether a communication signal of another UE having a predetermined priority is included in the first subframe or a second subframe related to the first subframe, and control a transmission of a communication signal of the UE through one of the second subframe and a third subframe related to the second subframe, wherein the first subframe and one of the second subframe or the third subframe, are used in the D2D communication of the UE, and wherein the controller is further configured to identify the alarm region by checking energy levels of entire alarm regions. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 22)
