Claim:
1. A method for transmitting device information for a Device To Device (D2D) service, the method comprising the steps of: transmitting, on a tone basis, a first information using a first tone in a first region; transmitting the first information through a second tone in a second region; and transmitting, on a sequence basis, a second information through a resource region including a plurality of tones in a third region, wherein the first information comprises a first part of bits of a device information, wherein the second information comprises a second part of the bits of the device information, wherein the second tone is located at a m-th symbol and a n-th subcarrier of the second region, wherein the m is a subcarrier index of the first tone and the n is a symbol index of the first tone, wherein at least one of a subcarrier and a symbol occupied by the resource region in the third region is determined based on at least one of the subcarrier index of the first tone and the symbol index of the first tone, wherein the first part of bits of the device information is identified based on a tone index of the first tone, wherein the tone index includes a symbol index and a subcarrier index of the first tone, wherein a size of the first information is determined based on a size of a frequency axis of the first region and a size of a time axis of the first region, and wherein mapping information between the first information and the first tone in the first region is determined based on the device information or tone index, dependent on the size of the first information.
