ossible combinations of S-SCH sequences. From the detected S-SCH sequence the UE detects the starting point of the sequence, which gives the frame synchronisation. The S-SCH sequence of the codes is also used to identify the primary scrambling code group. The UE checks from a predefined table which primary scrambling code group corresponds to the detected sequence of the codes. There are 64 possible S-SCH code sequence combinations that correspond to 64 primary scrambling code groups. After detecting the S-SCH sequence the mobile knows to which scrambling code group the scrambling code of a cell belongs. Detecting the Cell Primary Scrambling Code from the PCPICH The PCPICH contains the predefined pilot bit sequence, which is repeated in every frame (10 ms). The primary scrambling codes are divided into 64 scrambling code groups. Each scrambling code group consists of 8 codes, which give 512 primary scrambling codes. After the UE has detected the scrambling code group, it applies the trial-and-error method to detect which one of the 8 codes is the primary scrambling code of the cell. It applies each primary scrambling code from a scrambling code group until it finds which one gives the correct pilot bit sequence. When the UE is able to decode the PCPICH it can also decode the PCCPCH that carries the BCCH. It is then able to read the system information, which enables it to transmit or receive other common channels as well. The PCPICH pilot bit sequence is measured constantly to evaluate the quality of the cell. The exact implementation of a cell search depends on available preinformation (e.g. the cell primary scrambling code) and is UE vendor specific. The cell search procedure is based on usage of the P-SCH, S-SCH and PCPICH in the cell. The parameters related to the configuration of these channels are the transmit power parameters and the timing offset (T-offset), which configures the timing offset for each cell within a site. The offset is given to make sure that synchronization channels are transmitted at diff
