Abstract  Abstract

When the DCCH is mapped to the HS-DSCH, the terminal cannot reliably receive the HS-DSCH from the serving cell (eg, has not received any radio link control (RLC) grant mode feedback for the uplink measurement report or In general, a method and system are proposed for defining UE operation in the case of detecting that a common pilot channel (CPICH) level drops too low in a service HS-DSCH cell). The UE is automatically changed to the cell forward access channel (CELL_FACH) state and the uplink signaling is initiated through the random access channel (RACH) to inform the network node and request the appropriate in-cell HS-DSCH reconfiguration, or CELL_DCH state Set the normal R99 / R5 DPCH to recover the RRC signaling connection.
