摘要： The invention provides for method, system and node for ‘System Information’ (SI) message communication in an LTE deployed wireless communication system comprising of mapping at least a System Information Block (SIB) message into a System Information (SI) message in which SIB messages of same periodicity are mapped to a single SI message. The method further comprising segmenting dynamically the SI message exceeding predefined threshold value of SI bits known a priori that can be transmitted in any one subframe and transmitting the segmented SI messages in the corresponding SI-window wherein, the transmitted segment is indicated as part of previously transmitted segment via one bit indication taken out from the maximum number of bits that can be transmitted in a subframe and wherein if the indication bit is set to ‘1’ then the segment is part of previous frame that had non-zero indication bit and if indication bit is ‘0’ then the segment is the last segment of the System Information message. The method further decodes the segment by de-scrambling SI-RNTI; buffering the received segments based on indication bit; and assembling the received segments to form a single SI message, upon receiving the last segment indicated by the indication bit.
