METHOD FOR TRANSMITTING AND RECEIVING DATA WITH HIGH RELIABILITY IN A MOBILE COMMUNICATION SYSTEM SUPPORTING THE TRANSMISSION OF PACKET DATA, AND A DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: mobile communication systems for burst data transfer including transfer of control data for hybrid automatic retransmission request. ^ SUBSTANCE: absolute six-bit grant pointing to admissible maximal data transfer speed is generated for transmitting burst data of ascending communication line and sixteen-bit control of cyclic redundancy code referred to user equipment identifier is conducted by combining cyclic redundancy code control with user equipment identifier. Cyclic redundancy code referred to user equipment identifier and eight tail bits are added to six-bit absolute grant and summed-up bits are encoded at code speed of 1/3. Nineteen resultant encoded bits are coordinated with respect to speed in compliance with predetermined combination for coordinating speed of (1, 2, 5, 6, 7, 11, 12, 14, 15, 17, 23, 24, 31, 37, 44, 47, 61, 63, 64, 71, 72, 75, 7780, 83, 8485, 87, 88, 90) and transferred to user equipment. ^ EFFECT: enhanced reliability of control information transfer. ^ 16 cl, 5 dwg
