Mobile station applications ( 419 ) may include an SI unit ( 409 ) for piggy backing SI onto data stored in data buffer ( 421 ) and also for adding an indicator to the SI information. The scheduling information and/or incremental control information ( 501 ) is piggy backed onto a data PDU and also has a sequence number ( 503 ) and an indicator field ( 505 ) which is added by the SI unit, such as SI unit ( 409 ), in accordance with the embodiments. The indicator may be a bit map having four bit positions. A bit position having a binary "1" value may be utilized to indicate that a previous SN of SI information remains valid. For example, "0100" of the bit map sequence may indicate that SN # 3 is still valid. The base station or controller may then determine whether to implement or discard an SI information having the indicated SN.
