9.2A PDCCH/EPDCCH validation for autonomous uplink transmissions
36.2133GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Physical layer proceduresRelease 17TS
A UE shall validate a autonomous uplink assignment PDCCH/EPDCCH only if all the following conditions are met:
– the CRC parity bits obtained for the PDCCH/EPDCCH payload are scrambled with the AUL C-RNTI; and
– the ‘Flag for AUL differentiation’ indicates activating/releasing AUL transmission.
Validation is achieved if all the fields for the respective used DCI format are set according to Table 9.2A-1 or Table 9.2A-2.
If validation is achieved, the UE shall consider the received DCI information accordingly as a valid autonomous uplink transmission activation or release.
If validation is not achieved, the received DCI format shall be considered by the UE as having been received with a non-matching CRC.
