  • Patent number: 8514818
    Abstract: Systems and methods for providing HS-SCCH masking and unmasking operations using user equipment identification field in generating a user equipment specific masking sequence are disclosed. The 1/2 rate convolution coding and the rate matching operations required to form the UE specific masking sequence to mask and unmask high speed shared control channel (HS-SCCH) packets are performed in a single operation. Look up tables and matrix coefficients used to provide a simple computation method to generate the needed UE specific masking sequence are provided. Apparatus and methods to use the UE specific masking sequence to unmask the HS-SCCH packets in a packet based radio frequency signaling communication system are disclosed.
    Type: Grant

  • Patent number: 6437711
    Abstract: A method encodes an input data block with a block encoder. The block encoder is capable of processing consecutive coding blocks whose size has an upper limit which is smaller than the size of the input data block. The method comprises: determining the length of the input data block before encoding any of its data with the block encoder; dividing the input data block to a plurality of segments wherein all segments are of substantially equal size and no segment is larger than the upper limit; and processing each segment with the block encoder. If the last segment is shorter than the remaining segments, fill bits can be added to the last segment such that its length equals that of the remaining segments.
