摘要： The present invention relates to a method for configuring and searching HS-SCCHs of a multi-carrier cell in a TD-SCDMA system. The network side configures the configuration information of a HS-SCCH set for a UE and notifies the UE through high layer signaling, wherein each HS-SCCH corresponds to a frequency point of high speed shared resources; the UE divides the HS-SCCH set into several subsets, and HS-SCCHs of the same subset correspond to the same frequency points; the UE selects the minimum value N from the number of carriers supported by itself, the number of the frequency points, and the number of the HS-SCCH subsets; the UE searches each HS-SCCH subset to be searched in turn, and if a consistent HS-SCCH is found, then the UE stops searching the other HS-SCCHs of the subset, the UE moves said subset out of the group of the HS-SCCH subsets to be searched, and adds the found HS-SCCH into a valid HS-SCCH set to be monitored; if the number of the HS-SCCHs of the valid HS-SCCH set equals to N, then stop searching. The present invention can increase the efficiency of searching the HS-SCCHs by the UE with satisfying normal communication requires.
