In this paper, the ATSC 3.0 broadcast Radio Access Technology (RAT) is aligned with 3GPP 5G NR RAT in the context of 5G convergence starting in Release 16. The 5G system architecture release 16 includes a new 5G physical layer known as 5G NR “New Radio” and a “Cloud Native” 5G Core (5GC) using cloud computing. The 5GC is agnostic to the type of radio access technology used and is enabler of many types of convergence. A novel shared multi-tenant broadcast core network architecture designed to interwork with 5GC is discussed. With the 3GPP 5G NR unicast and Non-3GPP ATSC 3.0 broadcast synergistically aligned using methods of Release 16. This includes using 3GPP Access Traffic Steering, Switching, Splitting (ATSSS) and a multi-radio dual simultaneous connected User Equipment (UE). This aligns ATSC 3.0, the first forward looking (non-backward-compatible) native IP OFDM broadcast standard, with 3GPP LTE/5G unicast as a converged 5G vertical. The proposed method and architecture are orthogonal to LTE broadcast Release 16 and is synergistic to 5G NR mixed-mode multicast unicast in future.

ATSC 3.0 广播 5G 单播异构网络融合服务开始版本 16

在本文中，ATSC 3.0 广播无线电接入技术 (RAT) 在第 16 版开始的 5G 融合背景下与 3GPP 5G NR RAT 保持一致。5G 系统架构第 16 版包括一个新的 5G 物理层，称为 5G NR“新无线电”和使用云计算的“云原生”5G 核心网 (5GC)。5GC 与所使用的无线电接入技术类型无关，并且是多种类型融合的推动者。讨论了一种旨在与 5GC 互通的新型共享多租户广播核心网络架构。3GPP 5G NR 单播和非 3GPP ATSC 3.0 广播使用版本 16 的方法协同对齐。这包括使用 3GPP 接入流量转向、交换、拆分 (ATSSS) 和多无线电双同时连接用户设备 (UE)。这符合 ATSC 3.0，第一个前瞻性（非向后兼容）原生 IP OFDM 广播标准，将 3GPP LTE/5G 单播作为融合的 5G 垂直。所提出的方法和架构与 LTE 广播第 16 版正交，并且与未来的 5G NR 混合模式多播单播协同。
