Method and apparatus for recognizing radio link failures associated with HSUPA and HSDPA channels
Abstract:
A method and system for detecting radio link (RL) failures between a wireless transmit/receive unit (WTRU) and a Node-B are disclosed. When signaling radio bearers (SRBs) are supported by high speed uplink packet access (HSUPA), an RL failure is recognized based on detection of improper operation of at least one of an absolute grant channel (AGCH), a relative grant channel (RGCH), a hybrid-automatic repeat request (H-ARQ) information channel (HICH), an enhanced uplink dedicated physical control channel (E-DPCCH) and an enhanced uplink dedicated physical data channel (E-DPDCH). When SRBs are supported by high speed downlink packet access (HSDPA), an RL failure is recognized based on detection of improper operation of at least one of a high speed shared control channel (HS-SCCH), a high speed physical downlink shared channel (HS-PDSCH) and a high speed dedicated physical control channel (HS-DPCCH).
Abstract(Chinese):

公开了一种在无线发射/接收单元（WTRU）和节点B之间检测无线链路（RL）故障的方法和系统。 当通过高速上行链路分组接入（HSUPA）支持信令无线电承载（SRB）时，基于检测绝对授权信道（AGCH），相对授权信道（RGCH）中的至少一个的不正确操作来识别RL故障， 混合自动重传请求（H-ARQ）信息信道（HICH），增强型上行链路专用物理控制信道（E-DPCCH）和增强型上行链路专用物理数据信道（E-DPDCH）。 当通过高速下行链路分组接入（HSDPA）支持SRB时，基于检测到高速共享控制信道（HS-SCCH），高速物理下行链路共享信道（HS-SCCH） HS-PDSCH）和高速专用物理控制信道（HS-DPCCH）。
