The present invention relates to communicating control information in a mobile communication system, wherein the control information of a mobile terminal for scheduling an uplink channel may be notified to a network more quickly with less power. In an exemplary embodiment, a line card provides equalization feedback to a modem whenever changes to the equalization are beneficial. The apparatus also has aligning means, which includes a ridge for aligning the tapering means with the butt joint. Arranging the heap further includes comparing first and second nodes to determine which has the sought benefit within the heap, and ordering the peak node as the head of the heap. 0, \u03bdd1\u2212\u03bdd2>25, 0. Moreover, the digital data recordingreproducing method increases correction capability against several bytes to several tens bytes of errors generated at random without changing burst error correction length by performing this processing for respective PI codes by using interleave rules that are different as much as possible from one another.
