摘要： A fast random access method for the enhanced uplink dedicated channel of WCDMA system including: Network periodically set "EUDCH power offset" and "EUDCH power ramp step" and broadcast them to a UE via the system information block or transmit them via dedicated channel; and the UE calculates Preamble_Initial_power and preamble transmission power based on the received "EUDCH power offset" and "EUDCH power ramp step", respectively. By specially setting the transmission power offset for initial preamble and larger power ramp step, the initial transmission power of random access procedure is increased, and the probability of random access success is increased. Time needed for power probing is reduced, and the time needed for the random access is reduced. Values of the information elements newly added are set by the network according to the current uplink interference and the estimated possible number of the users for the fast random access.

摘要： A method for the terminal-to-terminal direct communication in the TDMA mobile communication system includes the following steps when making use of the uplink timeslots of the normal communication: in the initial phase, a sender still transmits a signal to a receiver according to its transmission timing for the normal communication; the receiver detects signals of its surrounding terminals that are in normal communication, and selects one with the strongest power as the strongest interference signal; the receiver detects the signal from the sender and compares the arrival time of the sender's signal with that of the strongest interference signal, and thereby obtains an adjustment control instruction for the sender, and feedback the control instruction to the sender; the sender adjusts its transmission timing according to the control instruction that it receives. This invention solves the synchronization problem of the direct communication in the TDD mobile communication system.
