Hi Alessandro,

take a look at the following lines in |pdsch_ue.c|. This should give you
an example on how to the decoded data can be accessed.

|for (uint32_t tb = 0; tb < SRSRAN_MAX_CODEWORDS; tb++) { if
(pdsch_cfg.grant.tb[tb].enabled) { srsran_netsink_write(&net_sink,
data[tb], 1 + (pdsch_cfg.grant.tb[tb].tbs - 1) / 8); } } |

Best regards,
Robert
