nr_fill_indication() fills CRC and RX requests, to be sent from L1 to L2. Before this commit, nr_fill_indication() is called when - we finally decoded LDPC (or not) - low signal on PUSCH This might happen at the same time, i.e., nr_fill_indication() might try to fill both CRC and RX, in the same list, from different threads. This can lead to this assertion: Assertion (crc->rnti == rx->rnti) failed! In handle_nr_ulsch() ../../../openair2/NR_PHY_INTERFACE/NR_IF_Module.c:190 mis-match between CRC RNTI e071 and RX RNTI 5e3b e.g., e071 is low energy, and while 5e3b related message are filled in one thread, e071 is being put into the message structure as well. At least that is my understanding. I could not actually reproduce this assertion; to be seen if it still happens.
