The method comprises estimating (410) a throughput gain of a paired scheduling relative to an unpaired scheduling for a UE pair comprising a first UE and a second UE, and for each of the first and the second UEs individually.

摘要： In network-based uplink scheduling, users are scheduled by the network for uplink communication between a user side and a network side. In this context, the invention provides an efficient estimation of User Equipment (UE) buffer status on the network side such as at Node B (20), for each of a number of users (10), and determines an uplink scheduling priority order of the users based on the network-estimated buffer status information. The users (10) are allocated communication resources based on the determined uplink scheduling priority order. In this way, the UE buffer status may be considered in the uplink scheduling procedure without explicit UE buffer status reports (that would waste valuable uplink transmission resources) from the UE side. This means that efficient scheduling and optimal exploitation of the uplink transmission resources are ensured, with clearly improved system performance as a result.
摘要翻译：在基于网络的上行链路调度中，用户由网络进行调度，用于用户侧和网络侧之间的上行链路通信。在本文中，本发明为多个用户（10）中的每个用户（10）提供对诸如在节点B（20）的网络侧的用户设备（UE）缓冲器状态的有效估计，并且确定上行链路调度优先级顺序用户基于网络估计的缓冲区状态信息。基于所确定的上行链路调度优先级顺序为用户（10）分配通信资源。以这种方式，可以在上行链路调度过程中考虑UE缓冲器状态，而没有来自UE侧的显式UE缓冲器状态报告（将浪费有价值的上行链路传输资源）。这意味着确保了上行链路传输资源的有效调度和优化利用，结果显着提高了系统性能。
