System information performance enhancements

A user equipment (UE) comprising:

• a memory;
• and
• at least one processor coupled to the memory, the memory storing instructions that are executable by the at least one processor, wherein the at least one processor is configured to execute the instructions and cause the UE to:
• receive a first signal carrying a first encoded information block including a first bit pattern associated with an information field;
• receive a second signal carrying a second encoded information block including a second bit pattern associated with the information field;
• determine a probability of occurrence for each bit-change pattern in a subset of a plurality of bit-change patterns associated with the information field, wherein:
• the plurality of bit-change patterns is associated with a system frame number (SFN);
• the subset of the plurality of bit-change patterns corresponds to one of the plurality of bit-change patterns indicating a single bit-change at a least significant bit;
• select one or more bit-change patterns from the subset of the plurality of bit-change patterns based on the one or more bit-change patterns having a higher probability of occurrence among the subset of the plurality of bit-change patterns than remaining bit-change patterns in the plurality of bit-change patterns;
• jointly decode the first encoded information block and the second encoded information block based on an assumption that a difference between the first bit pattern and the second bit pattern corresponds to the one or more bit-change patterns, wherein the jointly decoding is based on an assumption that the first encoded information block includes an even SFN and the second encoded information block includes an odd SFN;
• receive a third signal carrying a third encoded information block including a third bit pattern associated with the information field;
• and
• jointly decode the second encoded information block and the third encoded information block based on an assumption that the second encoded information block includes an even SFN in response to the jointly decoding the first encoded information block and the second encoded information block failing.

A non-transitory computer-readable medium having computer-executable code recorded thereon, the computer-executable code, when executed by one or more processors of a user equipment (UE), causes the UE to:

• receive a first signal carrying a first encoded information block including a first bit pattern associated with an information field;
• receive a second signal carrying a second encoded information block including a second bit pattern associated with the information field;
• determine a probability of occurrence for each bit-change pattern in a subset of a plurality of bit-change patterns associated with the information field, wherein:
• the plurality of bit-change patterns is associated with a system frame number (SFN);
• the subset of the plurality of bit-change patterns corresponds to one of the plurality of bit-change patterns indicating a single bit-change at a least significant bit;
• select one or more bit-change patterns from the subset of the plurality of bit-change patterns based on the one or more bit-change patterns having a higher probability of occurrence among the subset of the plurality of bit-change patterns than remaining bit-change patterns in the plurality of bit-change patterns;
• jointly decode the first encoded information block and the second encoded information block based on an assumption that a difference between the first bit pattern and the second bit pattern corresponds to the one or more bit-change patterns, wherein the jointly decoding is based on an assumption that the first encoded information block includes an even SFN and the second encoded information block includes an odd SFN;
• receive a third signal carrying a third encoded information block including a third bit pattern associated with the information field;
• and
• jointly decode the second encoded information block and the third encoded information block based on an assumption that the second encoded information block includes an even SFN in response to the jointly decoding the first encoded information block and the second encoded information block failing.
