Abstract:
1. A single frequency network (SFN) networking method in a time division-synchronous code division multiple access (TD-SCDMA) system, comprising the steps of: (A) deciding a networking configuration scheme by a universal mobile telecommunications system terrestrial radio access network (UTRAN) comprising deciding physical channel resources comprising frequencies and timeslots working at an N-frequency mode or a single frequency network (SFN) mode, wherein a time division or frequency division is provided between the physical channel resources of the N-frequency mode and those of the SFN mode, so that each of the physical channel resources is not able to work on both of the N-frequency mode and the SFN mode at the same time and at the same frequency, wherein the physical channel resources working at the SFN mode of a cell is identical to the physical channel resources working at the SFN mode of its neighboring cells, wherein each cell has at least a first TS wherein the timeslots of the SFN mode works at a downlink direction from the UTRAN to the UE, wherein if a second TS wherein the number of timeslots working at the SFN mode is independently configured among different frequencies in a same cell, so that the number of timeslots of the SFN mode at a frequency is independent of the number of timeslots of the SFN mode at another frequency, wherein a working mode of each of all downlink timeslots at a frequency is independently configured, so that whether a timeslot works at a certain mode is independent of a working mode of a last and next timeslot, wherein the timeslots working at the SFN mode use a multiple access mode; (B) based on the decided networking configuration scheme, configuring an intra-frequency cell info list information element and an inter-frequency cell info list information element in system information and measurement control messages by the UTRAN, wherein each of the intra-frequency cell info list information element and the inter-frequency cell info list information element comprises a cell information element, wherein a cell parameters identity (ID) information element is configured in the cell information element, and a timeslot number of the cell parameters ID information element is identified by a timeslot number information element in the cell information element; (C) transmitting signals over a servicing area by the UTRAN; and (D) receiving the system information and measurement control messages by a user equipment (UE) from the UTRAN, acquiring working mode configuration information of each frequency and each timeslot of a serving cell and neighboring cells, and judging whether there are duplicated cell information elements in the intra-frequency cell info list information element or the inter-frequency cell info list information element, wherein if a result of the judgment is yes, at a corresponding frequency of the cell information element, the UE affirms that the timeslot identified by the timeslot number information element works at the SFN mode, wherein if a result of the judgment is no, at a corresponding frequency of the cell information element, the UE affirms that the timeslot identified by the timeslot number information element works at the N-frequency mode.
