Question about UL OFDMA support in 5G-LENA

[Bara Sabbah]

  Hello everyone,

 I have a question regarding the current status of OFDMA support in the uplink in 5G-LENA. Both the documentation and several code comments state that OFDMA in the UL is not implemented. However, when inspecting the code ( particularly NrMacSchedulerOfdma::AssignULRBG)  it appears that uplink OFDMA‑like behavior is present, with allocations in both time (symbols) and frequency (RBGs) being assigned to multiple UEs  (e.g., RB allocation across multiple UEs within the same symbol).

I am a bit confused about the status of OFDMA in the uplink. Is OFDMA actually implemented in the UL and the documentation simply not up to date, or am I missing something?


Best regards,
Bara

OFDMA UL is there, but the logic is not the same as downlink. It needs to be updated.
