Method and apparatus for transmitting frames in talk-around direct communication

摘要

A permutated channel structure based on a block structure in talk-around direct communication is provided. A dedicated subchannel interferes with only one adjacent dedicated subchannel, even with a large synchronization error, by permutating the dedicated subchannels by cyclic shifts, whereby diversity gain can be maintained and interference between adjacent channels can be minimized.

1. A method for transmitting frames in direct communication, the method comprising:
assigning a plurality of mini-resource blocks (mRBs) to at least one subframe assigned for a dedicated channel, among a plurality of subframes included in the frames; calculating a number of cyclic shifts based on indices of the subframes and a number of dedicated subchannels included in a slot; cyclically shifting the mRBs according to the number of cyclic shifts; and transmitting frames including a plurality of cyclically shifted mRBs.
