OCUDU 26.10 adds NTN, 8T8R MIMO, and O-RAN Split 7.2b to open source RAN — The OCUDU Ecosystem Foundation released OCUDU 26.10 with 3GPP Release 17 NTN satellite support, enhanced beamforming and multi-beam operation, Split 7.2b, native 5G positioning, and security hardening. The release is available now; the community meets at the OCUDU Ecosystem Developer Summit on October 20–22 in Alexandria, Virginia. OCUDU · cmv4ug5sf9f6ab1f70986bf08

Duranta OpenAirInterface v3.0.0 is the first RAN+UE release on GitHub — Published October 10, v3.0.0 ships the full NR RAN and nrUE stack under CSSL v1.0, with CUDA/HIP/Aurora LDPC offload, a software O-RAN 7.2 O-RU, E3/dApps, scheduling for up to 100 UEs, NR-DC over F1, NRPPA, and expanded 7.2 fronthaul features; LTE RAN/UE branches remain but are not actively maintained.

Open5GS keeps PDU/PDN sessions during GUTI re-attach and re-registration — Merged PR #4847 defers session release until authentication, Security Mode Control, and the configured EIR check finish, so an unverified Attach or Registration Request using a registered UE’s GUTI no longer tears down active bearers prematurely.

Open5GS SMF tolerates duplicate PFCP REMOVE responses — PR #4851 ignores a PFCP REMOVE answer for a bearer already cleared by an earlier REMOVE (for example when Create Bearer and Delete Bearer both fail for the same EBI) and marks the Modify Bearer PFCP timeout callback as session-level.

OCUDU merges CUDA Gold-sequence and scrambling kernels — MR !1716 lands GPU Gold-sequence generation and scrambling as the next step after CRC kernels, splitting CUDA PHY work into reviewable merge requests on the dev branch. GitLab · cmv4ug5sr66fba6d6cfd7e0dd

OCUDU PDCP drops SDUs/PDUs above the TS 38.323 size limit — MR !1769 fixes an OSS-Fuzz abort in NIA2 integrity by enforcing the 9000-byte PDCP SDU maximum so oversize inputs cannot reach the MAC engine. GitLab · cmv4ug5st51c86cc06079920e

OCUDU PHY fuses PDxCH scaling into the OFDM modulator — MR !1736 (merged October 6) writes ci16 samples in one saturating sc_prod pass, removing the amplitude controller and per-port float scratch buffers from the PDxCH baseband path. GitLab · cmv4ug5sw6bd7b0b8fc022e4b

UERANSIM hardens NAS decoding per TS 24.501 — PR #811 (merged October 11) decodes each IE inside its own subView, skips unknown optional IEs, and applies §7.6–7.7 error handling so malformed NAS is less likely to crash nr-gnb or nr-ue. GitHub · cmv4ug5sy35c3b80c3c1639a8
