论文摘要
上行链路配置的赠款分配已在第三代伙伴关系项目中引入新广播版本15。这有利于支持超可靠和低延迟通信以实现工业通信，这是关键的第五代移动通信使用情况。这种调度机制使使用定期流量的用户可以轻松地传输其数据，并绕过需要进行调度请求和调度赠款的控制信号，并提供低延迟访问权限。为了促进超级可靠的通信，调度机制可以使用户可以在预定的时期内连续发送冗余传输。但是，如果流量是半确定性的，则当前的标准化赠款分配没有能力模仿流量，因为配置的赠款期间是预先配置和修复的。本文介绍了配置的赠款分配和前瞻性解决方案的标准化过程中的最新进步，以适应已配置赠款分配的半确定性交通行为。
Uplink configured Grant allocation has been introduced in 3rd Generation Partnership Project New Radio Release 15. This is beneficial in supporting Ultra-Reliable and Low Latency Communication for industrial communication, a key Fifth Generation mobile communication usage scenario. This scheduling mechanism enables a user with periodic traffic to transmits its data readily and bypasses the control signaling entailed to scheduling requests and scheduling grants and provides low latency access. To facilitate ultra-reliable communication, the scheduling mechanism can allow users to transmit consecutive redundant transmissions in a pre-defined period. However, if the traffic is semi-deterministic, the current standardized configured grant allocation is not equipped to emulate the traffic as the configured grant's period is pre-configured and fixed. This article describes the recent advancements in the standardization process in Release 15 and 16 for configured grant allocation and the prospective solutions to accommodate semi-deterministic traffic behavior for configured grant allocations.
