摘要: A method and arrangement in a first mobile terminal (600) for determining allocation of radio resources for DMO communication amongst a group of mobile terminals. M the first mobile terminal, a first determining module 600a determines a communication (Sout, Sin) with a second mobile terminal (602) of the group. A second determining module (600b) determines a resource element (RE) for communication by applying a predefined cryptographic function P based on a terminal identification (K)). The cryptographic function has been configured in the mobile terminals of the group to provide terminal-specific resource elements for different mobile terminals within respective radio frames. A communication module (600c) then communicates with the second mobile terminal (602), either by transmission or reception of the data, on the determined resource element (RE).
