NR BROADCAST CHANNEL TRANSMISSION Russian patent published in 2020 - IPC H04W48/16 

FIELD: physics.

SUBSTANCE: invention relates to transmission of system information in wireless communication networks. System information is received in synchronization signal unit (SS) from set of packets (SS) containing at least one SS unit. System information is multiplexed with information providing a time index indicating which SS is received from the set of SS packets. Method comprises steps of receiving, (410) information providing a time index, and receiving (430) system information, wherein system information is descrambled using a scrambling sequence generated (420) based on information providing a time index. Method also includes a step of determining (440) accuracy of information providing a time index based on an error detection code related to the received system information.

EFFECT: technical result is enabling the terminal or UE to determine as soon as possible whether the detected or received value of the time index, for example, obtained from the NR-TSS, is correct or not, in order to avoid unnecessary service signaling and delays in relation to the random access procedure.
