    • A signal transmission method and apparatus of a user equipment for a mobile communication system is provided for improving data transmission reliability and efficiency by transmitting data based on precise discrimination of the uplink transmission resource assignment messages indicative of initial transmission and retransmission. A signal transmission method of a user equipment for a mobile communication system receives an uplink transmission resource assignment message from a base station determines whether a Hybrid Automatic Repeat reQuest (HARQ) buffer is empty, and when the HARQ buffer is empty, transmits to the base station a Media Access Control Protocol Data Unit (MAC PDU) generated with reference to information contained in the uplink transmission resource assignment message.

    • Improving communication efficiency in handover re-establishing an ARQ entity in a mobile communication system is disclosed. The method includes transmitting first Packet Data Convergence Protocol (PDCP) Packet Data Units (PDUs) correctly received from the source cell, together with a special indication requiring reordering of the first PDCP PDUs, from a Radio Link Control (RLC) receiving buffer to a PDCP receiving entity when a handover command message from a source cell to a target cell is received; buffering the first PDCP PDUs in a PDCP PDU reordering buffer by the PDCP receiving entity in response to the special indication; and when a second PDCP PDU is received from the target cell through a new RLC receiving entity for the target cell, outputting third PDCP PDUs up to a PDCP PDU before a first missing PDCP PDU having a sequence number higher than that of the second PDCP PDU from the PDCP reordering buffer. In the method, a PDCP entity performs reordering, thereby improving efficiency of communication.
    • 公开了提高移动通信系统中重传ARQ实体的切换中的通信效率。 该方法包括将从源小区正确接收的第一分组数据收敛协议(PDCP)分组数据单元(PDU)以及需要从第一PDCP PDU重新排序的特殊指示从无线链路控制(RLC)接收缓冲区发送到 当从源小区到目标小区的切换命令消息被接收时,PDCP接收实体; 响应特殊指示,由PDCP接收实体缓冲PDCP PDU重排序缓冲器中的第一PDCP PDU; 并且当通过用于目标小区的新的RLC接收实体从目标小区接收到第二PDCP PDU时,在具有比第二PDCP PDU的序列号高的序列号的第一丢失PDCP PDU之前,将第三PDCP PDU输出直到PDCP PDU 从PDCP重新排序缓冲区。 在该方法中,PDCP实体执行重新排序,从而提高通信的效率。
