Abstract
To reduce the transmission energy and latency when servicing the users who are interested in a common popular content, the base station (BS) chooses to deliver the content to the users nearby with less power. After these users receive and cache the required content, they can act as relay users (RUEs) to serve those who are far away from the BS by means of Device-to-Device (D2D) and thus are called D2D users (DUEs). In such a scenario, how to classify the users into RUEs and DUEs and associate the DUEs to the RUEs is an important but not trivial problem. In this paper, we formulate the joint RUEs selection and DUEs association problem from a long-term perspective. To find a low complexity computational solution to the problem, we first propose an algorithm to select the RUEs based on the set criteria, and then a coalition formation game based algorithm is proposed for the DUEs association. We further prove that the proposed algorithm is convergent. Numerical results demonstrate that the algorithms we proposed yield notable gains compare with short-term optimal scheme and non-cooperative scheme.
