P1914.1 - Standard for Packet-based Fronthaul Transport Networks

Project Details

This standard specifies: 1) Architecture for the transport of mobile fronthaul traffic (e.g., Ethernet-based), including user data traffic, and management and control plane traffic. 2) Requirements and definitions for the fronthaul networks, including data rates, timing and synchronization, and quality of service. The standard also analyzes functional partitioning schemes between Remote Radio Units (RRUs) and Base-Band Units (BBUs) that improve fronthaul link efficiency and interoperability on the transport level, and that facilitate the realization of cooperative radio functions, such as massive Multiple-Input-Multiple-Output (massive MIMO) operational modes, Coordinated Multi-Point (CoMP) transmission and reception.

Active Projects	Active P1914.3a - Standard for Radio over Ethernet Encapsulations and Mappings Amendment 1: Encapsulation Enhancements and Elaborations, Additional Operation, Administration, and Maintenance (OAM) Functions, Management Model, Clarification on Relationships between Parameters This standard defines the encapsulation and mapping of radio protocols transported over Ethernet frames and Internet Protocol (IP) packets and the operation of the mappers and demappers. Structure-agnostic definitions are provided for any digitized radio data. Structure-aware definitions are provided for the Common Public Radio Interface (CPRI). Native mode definitions are provided for normal and compressed digitized radio in-phase and quadrature (I/Q) payload. Specifications are provided for parameters, control messages, and mechanisms that help operate, administrate, and maintain the mapping and demapping functions. A management model for this protocol is defined.
Existing Standards	Active 1914.3-2018 - IEEE Standard for Radio over Ethernet Encapsulations and Mappings The encapsulation and mapping of radio protocols for transport over Ethernet frames, using radio over Ethernet (RoE), are defined in this standard. Structure-agnostic definitions are provided for any digitized radio data. Structure-aware definitions are provided for the Common Public Radio Interface (CPRI(TM)). Native mode definitions are provided for digitized radio in-phase and quadrature (I/Q) payload.
