Abstract
A method, apparatus, and system for generating and transmitting a physical broadcast channel (PBCH) are provided. A base station may perform a first scrambling process on PBCHs in a time period before a channel coding, and perform a second scrambling process after the channel coding. PHCH payloads and PBCH DMRS may provide information bits to be used in the scrambling processes.
Claims20
An apparatus comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
- initialize, based on a cell identifier of a base station, a scrambling sequence generator to scramble a portion of each physical broadcast channel (PBCH) in eight consecutive radio frames, wherein each radio frame in the eight consecutive radio frames has a duration of 10 ms;
- determine a plurality of synchronization signal (SS) blocks in the eight consecutive radio frames, wherein each SS block comprises a PBCH;
- generate, based on the initialized scrambling sequence generator, a scrambling sequence to scramble the portions of each PBCH within the eight consecutive radio frames, wherein the scrambling sequence comprises four different sequence parts;
- scramble PBCHs in a first 20 ms of the eight consecutive radio frames by applying a first one of the four different sequence part;
- scramble PBCHs in a second 20 ms of the eight consecutive radio frames by applying a second one of the four different sequence part;
- scramble PBCHs in a third 20 ms of the eight consecutive radio frames by applying a third one of the four different sequence part;
- and
- scramble PBCHs in a fourth 20 ms of the eight consecutive radio frames by applying a fourth one of the four different sequence part.
