Low PHY-L1 offload engine

General Description

Comcores offers an O-RAN ready radio PHY-L1 engine (Layer 1) IP that implements 3GPP 36-series (LTE) and 38-series (NR) compliant radio protocol processing according to the O-RAN defined split point 7-2x. The IP is targeting the Radio Unit (RU) side and is scalable for any kind of RU deployment. The IP core has been tested in hardware and a demonstrator is available for early proof of concept. The IP uses general interfaces for easy integration with any O-RAN transport mapper solution towards the centralized baseband unit (CU) and any RF subsystem towards the antennas.

Key Features



Delivering Performance
  • Implements RU PHY-L1 LTE and NR compliant processing according to O-RAN functional split 7-2x for both RU category A and B including FFT/iFFT transformation, Cyclic Prefix insertion/removal, beamforming, PRACH filtering and precoding (RU category B only)
  • Supports any LTE and NR defined channel bandwidths up to 100 MHz with support for mixed numerology for up to 8 Component Carriers on up to 64 antennas
Easy to Use
  • Test bench is available both as stand-alone or with Comcores eCPRI solution integrated for support of O-RAN transportation
  • Simple and agnostic interfacing towards a O-RAN transport mapper with clear separations of U- and C-plane interfaces allows for easy integration
  • Configurable for many operating modes
Silicon Agnostic
  • Designed in VHDL and targeting any RTL implementation like ASICs, ASSPs and FPGAs.
  • Reduction of fronthaul bandwidth
  • O-RAN/eCPRI based Radio Units
  • Ethernet based fronthaul
