In the current code, in `set_tdd_config_nr` the number of slots to be configured is computed as: `int nb_slots_to_set = TDD_CONFIG_NB_FRAMES*(1<<mu)*NR_NUMBER_OF_SUBFRAMES_PER_FRAME;` where TDD_CONFIG_NB_FRAMES is 2, therefore the TDD configuration is done for 2 frames, while it should be done for 1 frame only. The macro is coming from legacy code. See thread in [2799](https://gitlab.eurecom.fr/oai/openairinterface5g/-/merge_requests/2799#note_139690)
