通过移动的终端的协作分集面临许多部署挑战，诸如安全性（因为终端必须检测伙伴的信号）、激励和强制包（因为用户必须被激励使用他们的终端来帮助其他人）以及巨大的资本投资（因为终端必须被修改以使它们准备好用于协作）。本文讨论了固定中继使能的用户合作，正在考虑在赢家项目部署超越3G无线通信网络。这些方案的运作方式是让两个用户在他们不知情的情况下进行合作。这些方案可以被看作是网络设施的附加部分，对两跳无线网络的成本、安全性和端到端（E2E）性能有着重要的影响。此外，所提出的方案可以用于许多网络，因为当前的终端不需要任何修改。
Cooperative diversity through mobile terminals is faced with a number of deployment challenges such as security (as terminals have to detect partner's signals), incentive and coercion packages (as users have to be motivated to use their terminals to assist others), and huge capital investment (as terminals have to be modified to make them ready for cooperation). This paper discusses fixed relay-enabled user cooperation that are being considered in the WINNER project for deploying beyond 3G wireless communication networks. The schemes operate by engaging two users in cooperation without their knowledge. The schemes which can be viewed as an add-on to network facility have significant impact on the costs, security and end-to-end (E2E) performance of two-hop wireless networks. In addition, the proposed schemes can be used in a number of networks since current terminals do not require any modifications.
