Figure 8.148-1: PSCell ID
The "MNC digit 3" field shall be coded as "1111" if the MNC contains only two digits.
The NR CGI field shall consist of 36 bits. The NR CGI field shall start with Bit 4 of octet 7, which is the most significant bit. Bit 1 of Octet 12 is the least significant bit. The coding of the NR CGI is the responsibility of each administration. Coding using full hexadecimal representation (binary, not ASCII encoding) shall be used.
