    • A method and apparatus for managing a collision in random access channel (RACH) access transmissions are disclosed. A wireless transmit/receive unit (WTRU) transmits WTRU -dependent information (106) to confirm that a detected acquisition indicator (AI) (104) is intended to the WTRU. The WTRU - dependent information (106) may be transmitted separately after detecting the AI (104), may be transmitted along with a RACH preamble (102), or may be sent in an E-RACH message (110). The WTRU -dependent information (106) may be a random number, a sequence or scrambling code randomly selected from a pre- determined set of sequences or scrambling codes. Alternatively, the WTRU- dependent information (106) may be a pre -configured identifier, or information derived from the pre -configured identifier. Alternatively, after detecting an AI (104), the WTRU may randomly select an enhanced dedicated channel (E-DCH) resource from a set of E-DCH resources associated with an RACH resource used for transmission of the RACH preamble (102) and transmit an E-RACH message (110) using the selected E-DCH resource.
    • 公开了一种用于管理随机接入信道(RACH)接入传输中的冲突的方法和装置。 无线发射/接收单元(WTRU)发送WTRU相关信息(106)以确认检测到的获取指示符(AI)(104)是针对WTRU。 可以在检测到AI(104)之后单独发送WTRU依赖信息(106),可以与RACH前导码(102)一起发送,或者可以在E-RACH消息(110)中发送。 WTRU相关信息(106)可以是从预定的序列或扰码集合中随机选择的随机数,序列或扰码。 或者,WTRU相关信息(106)可以是预配置的标识符,或者是从预先配置的标识符导出的信息。 或者,在检测到AI(104)之后,WTRU可以从与用于发送RACH前导码(102)的RACH资源相关联的一组E-DCH资源中随机选择增强型专用信道(E-DCH)资源,并发送 使用所选择的E-DCH资源的E-RACH消息(110)。
