Abstract

Claims (18)

1 . A method for use in a base station, the method comprising:

generating a plurality of bits, the plurality of bits comprising a master information block (MIB) transport block and cyclic redundancy check (CRC) bits;

mapping each of the plurality of bits to bit channels using polar encoding, wherein at least a portion of the plurality of bits indicating timing information and a system frame number (SFN) are mapped to the bit channels based on content associated with the portion of the plurality of bits and a reliability associated with each of the bit channels;

rate matching, via repetition, coded bits associated with mapping each of the plurality of bits to the bit channels; and

sending a physical broadcast channel (PBCH) transmission, the PBCH transmission comprising the rate matched coded bits.

2 . The method of claim 1 , wherein the PBCH transmission further comprises bits associated with a synchronization signal (SS) block index.

3 . The method of claim 1 , wherein the PBCH transmission further comprises control resource set information.

4 . The method of claim 1 , wherein the bits that indicate timing information and the CRC bits are provided to reliable bit channels.

5 . The method of claim 1 , wherein the plurality of bits further comprises beam information bits.

6 . A base station comprising a processor and a memory, the processor and the memory configured to:

generate a plurality of bits, the plurality of bits comprising a master information block (MIB) transport block and cyclic redundancy check (CRC) bits;

map each of the plurality of bits to bit channels using polar encoding, wherein at least a portion of the plurality of bits indicating timing information and a system frame number (SFN) are mapped to the bit channels based on content associated with the portion of the plurality of bits and a reliability associated with each of the bit channels;

rate match, via repetition, coded bits associated with mapping each of the plurality of bits to the bit channels; and

send a physical broadcast channel (PBCH) transmission, the PBCH transmission comprising the rate matched coded bits.

7 . The base station of claim 6 , wherein the PBCH transmission further comprises bits associated with a synchronization signal (SS) block index.

8 . The base station of claim 6 , wherein the PBCH transmission further comprises control resource set information.

9 . The base station of claim 6 , wherein the bits that indicate timing information and the CRC bits are provided to reliable bit channels.

10 . The base station of claim 6 , wherein the plurality of bits further comprises beam information bits.
