本文提出了一种多用户对称协作通信网络的协作策略。两个用户的协作策略不适合多用户网络，因为多用户网络中只有部分用户参与协作。为了解决这个问题，首先提出了一种轮流执行的多用户协作框架，并建立了协作条件。其次，通过准入控制算法获得用户的最大可行协作子集。然后，利用合作博弈论中的NBS（纳什讨价还价解决方案）提出了最优带宽分配框架。仿真结果表明，该策略能够有效地找到用户的协作子集，并获得比非协作策略更好的传输速率。
This paper proposes a cooperative strategy for multi-user symmetrical cooperative communication networks. The cooperative strategy for two users is not suitable for the multi-user networks, where only part of the users participate in cooperation. To solve this problem, first, a multi-user cooperative framework executed in turn is presented and the cooperative condition is established. Second, the users' maximum feasible cooperative subset is obtained via the admission control algorithm. Then, an optimal bandwidth allocation framework is proposed utilizing NBS (Nash bargaining solution) from cooperative game theory. Simulation results demonstrate that the proposed strategy could find the users' cooperative subset effectively, and obtain better transmission rates than the non-cooperative strategy.
