Patent ID: 8189581

Claim:
A method for transmitting broadcast channel information as part of a broadcast channel signal in a wireless communication system, the broadcast channel signal having one or more transmission intervals, each transmission interval including a plurality of transmissions, where one or more of the transmissions are active frames in which the broadcast channel information to be transmitted as part of each broadcast channel signal includes an invariant portion that remains static for each of the active frames within a particular transmission interval, and a variant portion that predictably changes with each successive active frame, the method comprising: subdividing the variant portion into an invariant subportion and a variant subportion, where the variant subportion includes at least one bit which changes value within the particular transmission interval; identifying the invariant portion and invariant subportion from the broadcast channel information for each active frame, thereby forming invariant broadcast channel information for each active frame within a transmission interval that does not vary; encoding the invariant broadcast channel information for each active frame within a transmission interval with a transmission specific configuration, wherein each active frame is encoded with a distinct transmission specific configuration based upon the position of the active frame relative to the beginning boundary of the transmission interval; and transmitting the encoded invariant broadcast channel information for each active frame of each transmission interval in sequence thereby forming the broadcast channel signal.
