Patent ID: 7899051

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; combining the invariant portion with the invariant subportion of the variant portion; encoding the combined invariant portion and invariant subportion of the variant portion; encoding the variant subportion, separate from the combined invariant portion and invariant subportion of the variant portion; and transmitting the encoded combined invariant portion and invariant subportion of the variant portion, and the separately encoded variant subportion for each active frame of each transmission interval in succession thereby forming the broadcast channel signal.
