Method of configuring and searching high speed shared control channel of multi-carrier cell
First Claim
1. A method for configuring and searching high speed shared control channels HS-SCCHs in a multi-carrier cell, which is applied to a Time Division Synchronization Code Division Multiple Access system, and the method comprises the following steps:
- (a) the network side configuring the configuration information of a high speed shared control channel HS-SCCH set for a mobile terminal UE and notifying the UE through a high layer signaling, wherein the configuration information includes the information about the frequency points of high speed shared resources to which each HS-SCCH corresponds and the information about the number of the frequency points of the high speed shared resources;
(b) after receiving the high layer signaling, the UE saving the HS-SCCH set, and dividing it into several HS-SCCH subsets, wherein the HS-SCCHs in the same subset correspond to the information about the same frequency point;
(c) when the UE searches the HS-SCCHs, it first selects the minimum value represented as N from the number of carriers supported by the UE itself, the number of the frequency points of the high speed shared resources configured by the network side and the number of the HS-SCCH subsets, and adding all HS-SCCH subsets into a group of the HS-SCCH subsets to be searched;
(d) the UE searching each HS-SCCH subset to be searched in turn, and if the UE finds a HS-SCCH being consistent with its own identification in a subset, then stopping searching the other HS-SCCHs in the subset, the UE moving the subset out of the group of the HS-SCCH subsets to be searched, and adding the found HS-SCCH into a valid HS-SCCH set, and monitoring all HS-SCCHs in the valid HS-SCCH set; and
(e) the UE judging whether the number of the HS-SCCHs in the valid HS-SCCH set equals to N or not, if not, returning to step (d), and if yes, stopping searching and end.

Abstract
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.
