Version FH oran_release_bronze_v1.1, Aug 2020¶
Add profile and support for LTE.
Add support for the 32x32 massive mimo scenario. Up to 2 cells demo showed with testmac
mmWave RRH integration. Address regression from the previous release.
Integrate block floating-point compression/decompression.
Enhance C-plane for the Category B scenario.
Version FH oran_release_bronze_v1.0, May 2020¶
Integration and optimization of block floating point compression and decompression.
Category B support
Add support for alpha and beta value when calculating SFN based on GPS time.
Support End to End integration with commercial UE with xRAN/ORAN RRU for both mmWave and sub-6 scenarios
Version FH oran_release_amber_v1.0, 1 Nov 2019¶
Second version released to ORAN in support of Release A
Incorporates support for 5G NR sub 6 and mmWave
Support for Application fragementation under Transport features was added
This release has been designed and implemented to support the following numerologies defined in the 3GPP
specification * Numerology 0 with bandwidth 5/10/20 MHz with up to 12 cells * Numerology 1 with bandwidth 100MHz with up to 1 cell * Numerology 3 with bandwidth 100MHz with up to 1 cellThe feature set of xRAN protocol should be aligned with Radio Unit (O-RU) implementation
Inter-operability testing (IOT) is required to confirm correctness of functionality on both sides
The following mandatory features of the ORAN FH interface are not yet supported in this release
RU Category Support of CAT-B RU (i.e. precoding in RU)
Beamforming Beam Index Based and Real Time BF weights
Transport Features QoS over FrontHaul
Version FH seedcode_v1.0, 25 Jul 2019¶
This first version supports only mmWave per 5G NR and it is not yet
optimized
It is a first draft prior to the November 2019 Release A
The following mandatory features of the ORAN FH interface are not yet
supported in this initial release
RU Category Support of CAT-B RU (i.e. precoding in RU)
Beamforming Beam Index Based and Real Time BF weights
Transport Features QoS over FrontHaul and Application Fragmentation
