    • Urgent data is scheduled in a wireless communication system including at least one wireless transmit/receive unit (WTRU) and at least one Node-B. The WTRU includes a re-ordering release timer. The Node-B includes a buffer, a lifespan (or maximum allowed delay) timer and a high speed downlink packet access (HSDPA) scheduler. The HSDPA scheduler determines whether there is at least one protocol data unit (PDU) in the buffer whose lifespan (maximum allowed delay) timer or re-ordering release timer will expire if the PDU is not transmitted in a next N transmission timing interval (TTI), where N is a design parameter. If so, the PDU is treated as urgent data whereby a sequence of WTRUs , (i.e., users), scheduled to receive urgent data is arranged in an order of decreasing priority, and a more conservative modulation and coding scheme (MCS), multiple code transmission and a different redundancy reversion are considered for use.
    • 在包括至少一个无线发射/接收单元(WTRU)和至少一个节点B的无线通信系统中调度紧急数据。 WTRU包括重新排序释放定时器。 节点B包括缓冲器,寿命(或最大允许延迟)定时器和高速下行链路分组接入(HSDPA)调度器。 HSDPA调度器确定缓冲器中是否存在至少一个协议数据单元(PDU),其寿命(最大允许延迟)定时器或重新排序释放定时器将在下一个N个传输定时间隔(TTI)中不发送PDU ),其中N是设计参数。 如果是这样,则将PDU视为紧急数据,由此调度接收紧急数据的一系列WTRU(即,用户)以优先级降低的顺序排列,并且采用更保守的调制和编码方案(MCS),多个码 传输和不同的冗余反转被考虑使用。
