网络密度对非公有URLLC工厂网络性能的影响
Impact of Network Densification on the Performance of a Non-Public URLLC Factory Network
摘要：
例如通过在现有移动通信网络内添加新的扇区或站点来使网络部署致密化传统上是提高系统覆盖和容量的有效方式。即使是超可靠低延迟通信（URLLC）服务也是如此，但总体情况和不同部署选项的可行性将取决于所讨论的URLLC服务的特性。具有宽松的延迟要求的URLLC服务允许多次传输尝试，可以容忍相当程度的小区间干扰，同时仍然能够保证所有用户的期望服务质量，这使得可以通过添加具有全向或定向天线的新gNodeB来提高URLLC服务容量。然而，当URLLC服务需要不允许重传的极低延迟时，系统性能变得对小区间干扰非常敏感，这意味着实际上gNodeB应该配备有波束成形天线以达到高水平的URLLC服务容量。最后，有源分布式天线系统可能是确保整个期望服务区域的良好覆盖的有效方式。
英文摘要：
Densification of the network deployment, for example by adding new sectors or sites within an existing mobile communication network, has traditionally been an efficient way to improve the system coverage and capacity. That will be the case even for the ultra-reliable low-latency communication (URLLC) services, but the overall situation and the feasibility of the different deployment options will depend on the characteristics of the URLLC service in question. URLLC services with relaxed latency requirements, allowing multiple transmission attempts, can tolerate a decent level of inter-cell interference while still being able to guarantee the desired quality-of-service for all users, which makes it possible to improve the URLLC service capacity by adding new gNodeBs with omnidirectional or directional antennas. However, when the URLLC services require extremely low latency that do not allow for retransmissions, the system performance becomes quite sensitive to the inter-cell interference, which means that in practice the gNodeBs should be equipped with beamformed antennas to reach high levels of URLLC service capacity. Finally, an active distributed antenna system could be an efficient way to secure good coverage throughout the desired service area.
