PBCH decoding with payload change detection

An apparatus for wireless communication, comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• monitor a plurality of master information block broadcasts from a base station to obtain a first set of samples associated with a first prior transmission time interval (TTI) and a second set of samples associated with a current TTI;
• identify a payload change in the master information block broadcasts between the first set of one or more prior TTIs and the current TTI based at least in part on a comparison between the first set of samples and the second set of samples;
• modify the first set of samples based at least in part on the identified payload change;
• and
• decode a master information block based at least in part on a combination of the modified first set of samples and the second set of samples.

A non-transitory computer-readable medium storing code for wireless communication, the code comprising instructions executable by a processor to:

• monitor a plurality of master information block broadcasts from a base station to obtain a first set of samples associated with a first prior transmission time interval (TTI) and a second set of samples associated with a current TTI;
• identify a payload change in the master information block broadcasts between the first set of one or more prior TTIs and the current TTI based at least in part on a comparison between the first set of samples and the second set of samples;
• modify the first set of samples based at least in part on the identified payload change;
• and
• decode a master information block based at least in part on a combination of the modified first set of samples and the second set of samples.
