(54) Title: SYSTEM INFORMATION PERFORMANCE ENHANCEMENTS (57) : Wireless communications systems and methods related to system information communications and decoding are provided. In one embodiment, a wireless communication device receives one or more known bits. The wireless communication device receives a first encoded information block. The wireless communication device decodes the first Broadcast Master Information HBO) 410 encoded information block to generate a first information block based on Extract known Decode and the one or more known bits. In one embodiment, a wireless communica- tion device receives a first encoded information block including a first bit bits 412 pattern. The wireless communication device receives a second encoded information block including a second bit pattern. The wireless communi- Monitor Master Information 415 cation device jointly decodes the first encoded information block and the second encoded information block based on an assumption that a differ- Perform random access 420 ence between the first bit pattern and the second bit pattern is within a subset of a plurality of bit-change patterns.
