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.

摘要： A method for transmitting a short signaling in a Media Access Control-e Packet Data Unit (MAC-e PDU) includes sending control information bits incorporated with padding bits of the MAC-e PDU considering the padding bits from a User Equipment (UE) to a Node B, and sending a scheduling signaling from a service Node B to the UE according to the control information bits. Scheduling request information is transmitted with the existing padding bits. If every Transmission Time Interval (TTI) has padding bits, the UE may send the scheduling request signaling to Node B in every TTI. Therefore, the reference is provided for the Node B, and no extra load is caused to the system.

摘要： The present invention describes that the C-RNTIs are grouped based on the random access preamble sequence, the transmission sub-frame and the transmission random access channel information used for the user equipment and detected by the base station. In such a way, the indicating information bits needed by C-RNTI allocation are decreased and the signaling overhead needed by C-RNTI allocation is also decreased. In addition, the random access process is optimized and the random access performance is improved.

摘要： Provided is a method for transitioning between a distributed transmission mode and a localized transmission mode, including transmitting, by a Base Station (BS), a measurement control message to a User Element (UE), wherein the UE makes corresponding measurement and transmits a required measurement report message to the BS and the BS transmits a transition indicator message of new mode to the UE based on measurement report message sent from the UE; and commencing CQI reporting and a downlink transmission of a new mode between the UE and the BS. The BS can choose a more appropriate transmission mode for the downlink transmission based on changing characteristics of the channel in the time domain and the frequency domain.
