  • Patent number: 8261154
    Abstract: A continuous redundancy check method and apparatus receives (110) at least one data bit of a block's payload, calculates (120) a partial redundancy check value using the at least one data bit, compares (130) the partial redundancy check value with a reference value, and stores (134, 138) in an index an indication of whether the calculated redundancy check value matched the reference value. Meanwhile, the at least one data bit is also stored (140) in a data memory. As additional data bits of the payload are received, cumulative partial redundancy check values are calculated and compared to the reference value. When the complete payload has been stored (140), the index is analyzed (160, 165) to determine if a block error has been detected by the redundancy check functions. This continuous redundancy check method and apparatus allows a receiver to quickly determine whether a block error has occurred, especially when there may be padding (or dummy) bits in the block's payload.

  • Patent number: 8131286
    Abstract: A technique for providing broadcast services to a subscriber station includes determining (904) when a first broadcast frame that is to be transmitted on a broadcast channel includes broadcast information that is to be received by the subscriber station. Next, cellular information that is included within a first cellular frame and that is to be received by the subscriber station is scheduled (906), based on the determining, to avoid conflict between receipt of the cellular information and the broadcast information at the subscriber station. Finally, based on the scheduling, the first cellular frame is transmitted (908) on a cellular channel.
