System information message communication by dynamic segmenting of SI messages in a wireless communication system

A method performed in an LTE deployed wireless communication system comprising:

• receiving System Information (“SI”) configuration information over SIB Type 1 (SIBI) and receiving SI-Segments scrambled with SI-RNTI;
• decoding the received SI-Segments by de-scrambling SI-RNTI;
• and
• buffering the received segments as part of previously transmitted segment when one bit indication is received with bit set to ‘1’ for all transmitted segments and assembling the received segments to form a single SI message when indication bit ‘0’ is received as part of last segment.

The eNodeB in an LTE deployed wireless communication system comprising:

• a mapping module, comprising circuitry that maps SIB messages of same periodicity to a single SI message;
• a segmenting module, comprising circuitry that segments dynamically the SI message exceeding predefined threshold value of SI bits that can be transmitted in any one subframe;
• and
• a transmitting module, comprising circuitry that transmits the segmented SI messages in a corresponding SI-window, wherein, the transmitted segment is included as part of previously transmitted segment via one bit indication taken out from the maximum number of transmittable bits in a subframe and wherein when the indication bit is 1 then the segment is part of previous frame that had non-zero indication bit and when indication bit is ‘0’ then the segment is the last segment of the System Information message.

The Wireless communication system comprising:

• an eNodeB for SI message communication on a wireless channel over which the transmitter and receivers communicate in an LTE deployed wireless communication system comprising of:
• a mapping module, comprising circuitry that maps SIB messages of same periodicity to a single SI message;
• a segmenting module, comprising circuitry that segments dynamically the SI message exceeding predefined threshold value of SI bits that can be transmitted in any one subframe;
• and
• a transmitting module, comprising circuitry that transmits the segmented SI messages in a corresponding SI-window, wherein, the transmitted segment is included as part of previously transmitted segment via one bit indication taken out from the maximum number of transmittable bits in a subframe and wherein when the indication bit is set to ‘1’ then the segment is part of previous frame that had non-zero indication bit and when indication bit is ‘0’ then the segment is the last segment of the System Information message.
