摘要： The disclosure discloses a method for sharing a frequency spectrum between a GSM system and a LTE system. The method includes: avoiding fixed channels of the LTE system of a current cell when allocating frequency points of the GSM system to the current cell and a neighbour cell interfering with the current cell; frequency domain resources allocated to users and indicated by Physical Downlink Share Channels (PDSCHs) and Physical Uplink Share Channels (PUSCHs) of the LTE system are not located on same frequency resources with frequency points of the GSM system of the current cell and the neighbour cell interfering with the current cell; and for Physical Control Format Indicator Channels (PCFICHs) and Physical Hybrid ARQ Indicator Channels (PHICHs) of the LTE system, avoiding the PCFICHs and the PHICHs of the LTE system when allocating frequency points of the GSM system to the current cell and the neighbour cell interfering with the current cell, or allocating, by the LTE system, an appropriate Cell Identification (CellID) to avoid the frequency points of the GSM system of the current cell and the neighbour cell interfering with the current cell. The disclosure further discloses a system for sharing a frequency spectrum. According to the method and the system of the disclosure, the GSM system is able to transit to the LTE system smoothly while frequency spectrum utilization is improved.
摘要翻译：本公开公开了一种用于共享GSM系统和LTE系统之间的频谱的方法。该方法包括：当将GSM系统的频点分配给当前小区和相邻小区干扰当前小区时，避免当前小区的LTE系统的固定信道; 分配给用户并由物理下行链路共享信道（PDSCH）和物理上行链路共享信道（PUSCH）指示的频域资源与当前小区和相邻小区的GSM系统的频点不在同一频率资源上干扰当前单元格; 和用于LTE系统的物理控制格式指示符信道（PCFICH）和物理混合ARQ指示信道（PHICH），在将GSM系统的频点分配给当前小区和相邻小区时，避免了PCFICH和LTE系统的PHICH 干扰当前小区或由LTE系统分配适当的小区标识（CellID），以避免当前小区的GSM系统和相邻小区干扰当前小区的频点。本公开还公开了一种用于共享频谱的系统。根据本公开的方法和系统，GSM系统能够在频谱利用率提高的同时顺利地转移到LTE系统。
