This letter considers the development of transmission strategies for the downlink of massive multiple-input multiple-output networks, with the objective of minimizing the completion time of the transmission. Specifically, we introduce a session-based scheme that splits time into sessions and allocates different rates in different sessions for the different users. In each session, one user is selected to complete its transmission and will not join subsequent sessions, which results in successively lower levels of interference when moving from one session to the next. An algorithm is developed to assign users and allocate transmit power that minimizes the completion time. Numerical results show that our proposed session-based scheme significantly outperforms conventional non-session-based schemes.

数据大小感知下行链路大规模 MIMO：基于会话的方法


这封信考虑了大规模多输入多输出网络下行链路传输策略的开发，其目标是最小化传输的完成时间。具体来说，我们引入了一种基于会话的方案，该方案将时间分割成多个会话，并在不同的会话中为不同的用户分配不同的费率。在每个会话中，选择一个用户来完成其传输并且不会加入后续会话，这导致从一个会话移动到下一个会话时干扰水平逐渐降低。开发了一种算法来分配用户并分配发射功率，以最大限度地缩短完成时间。数值结果表明，我们提出的基于会话的方案显着优于传统的非基于会话的方案。
