一种无线网络设备
摘要：
本发明公开了一种无线网络设备。该无线网络设备包括：处理器，被配置成从无线发射/接收单元（WTRU）接收随机接入前同步码；其中所述处理器还被配置成传送下行链路传输的控制部分的公共区域中的至少一个控制信道元素（CCE）中的控制信息的格式；其中所述控制信息指示所述下行链路传输的数据部分中的资源分配；以及其中所述控制信息具有被与从所述WTRU接收的随机接入前同步码关联的随机接入无线电网络临时身份（RA‑RNTI）掩码的循环冗余码（CRC）；以及其中所述处理器还被配置成在所指示的所述数据部分的资源分配中传送指派给所述WTRU的随机接入响应。
摘要（英）：

A method and apparatus for supporting a random access using a random access channel (RACH) are disclosed. Each of a plurality of wireless transmit/receive units (WTRUs) sends a random access request to a base station on an uplink RACH preamble. A RACH Response, sent by the base station, is received by each WTRU. A control signal portion of the RACH Response indicates the location of the RACH Response message portion. The RACH Response control signal comprises multiple control channel elements (CCE), where each WTRU is allocated a respective CCE to provide its unique RACH Response control signal. The WTRU is configured to locate its intended CCE from among the multiple CCEs sent by the base station.
