sib 1 presence bitmap from most recent serving cell according to another aspect of the present invention when the client terminal does not have stored sib 1 presence bitmap information for any neighbor cell and the sib 1 decode attempt using the sib 1 presence bitmap sfns for serving enb also fails then the client terminal may attempt to receive sib 1 in all the sfns where sib 1 may be mapped p 1 p 2 p 3 and p 4 according to an aspect of the present invention the client terminal may turn off some of its subsystems for the subframe 5 in sib 1 sfns p 1 or p 2 or p 3 or p 4 where the client terminal does not attempt to receive sib 1 as per the stored sib 1 presence bitmap and sfn periodicity based on the 3gpp lte wireless communication system specifications unlike the sib 1 the si messages reception may be attempted in all the subframes within the si window typically the client terminal may attempt to receive si messages in all the subframes within the si window the present invention provides a method for the client terminal to receive the si messages based on the stored information about.
