PCI是无线通信系统的关键参数,5G系统定义了1008个PCI,每个小区在选择PCI的时候要避免PCI冲突。PCI冲突包括PCI碰撞(Collision)和PCI混淆(Confusion)。PCI碰撞表示相邻的两个小区A和B的PCI相同,用户设备(User Equipment,UE)在两小区的重叠区域能同时收到这两个小区的信号,由于A和B的PCI相同,导致UE在此区域发生切换失败和掉线的几率增大;PCI混淆表示与小区A同频的两个(B和C)或多个邻区的PCI相同,由于A、B和C的PCI相同,导致UE切换失败以及掉线。PCI is a key parameter of the wireless communication system. The 5G system defines 1008 PCIs. Each cell should avoid PCI conflicts when selecting PCIs. PCI conflicts include PCI collision (Collision) and PCI confusion (Confusion). A PCI collision indicates that the PCIs of two adjacent cells, A and B, are the same. User Equipment (UE) can simultaneously receive signals from the two cells in the overlapping area of the two cells. Since the PCIs of A and B are the same, The probability of UE handover failure and disconnection in this area increases; PCI confusion means that the PCIs of two (B and C) or more neighboring cells on the same frequency as cell A are the same. Since the PCIs of A, B, and C are the same, Causes the UE to fail to handover and disconnect.

本发明公开的5G物理小区标识配置方法,在为小区配置PCI时,通过空口侦听获取待配置小区的各个邻区的邻区频点信息、邻区PCI和邻区系统信息;根据所述邻区频点信息、所述邻区PCI和所述邻区系统信息过滤PCI候选列表中的候选PCI;根据所述PCI候选列表中剩余的候选PCI自动配置所述待配置小区的PCI。一方面,降低人工成本,另一方面提高PCI配置效率,减少出错率。In the 5G physical cell identifier configuration method disclosed in the present invention, when a PCI is configured for a cell, the adjacent cell frequency point information, the adjacent cell PCI and the adjacent cell system information of each adjacent cell of the to-be-configured cell are acquired through air interface listening; The area frequency point information, the adjacent area PCI and the adjacent area system information filter the candidate PCIs in the PCI candidate list; the PCI of the to-be-configured cell is automatically configured according to the remaining candidate PCIs in the PCI candidate list. On the one hand, it reduces labor costs, and on the other hand, it improves the efficiency of PCI configuration and reduces the error rate.

进一步的,如图5所示,Q1表示待配置小区,Q4表示待配置小区的异频邻区,Q5表示异频邻区Q4的与所述待配置小区Q1同频的邻区。S50也可以避免PCI混淆,避免在待配置小区的频率与异频邻区的邻区频率相同时,待配置小区的PCI与异频邻区的邻区PCI相同。其中,S50包括:根据所述邻区频点信息和所述邻区系统信息获得异频邻区系统信息SIB4;从所述异频邻区系统信息中获取各个异频邻区的与所述待配置小区同频的邻区的PCI;从所述PCI候选列表中过滤除去所述各个异频邻区的与所述待配置小区同频的邻区的PCI。Further, as shown in FIG. 5 , Q1 represents the cell to be configured, Q4 represents the inter-frequency adjacent cell of the to-be-configured cell, and Q5 represents the adjacent cell of the inter-frequency adjacent cell Q4 having the same frequency as the to-be-configured cell Q1. S50 can also avoid PCI confusion, and avoid that when the frequency of the cell to be configured is the same as the frequency of the adjacent cell of the inter-frequency adjacent cell, the PCI of the cell to be configured is the same as the PCI of the adjacent cell of the inter-frequency adjacent cell. Wherein, S50 includes: obtaining inter-frequency adjacent cell system information SIB4 according to the adjacent cell frequency point information and the adjacent cell system information; Configuring the PCI of the adjacent cells of the same frequency of the cell; filtering and removing the PCI of the adjacent cells of the same frequency as the to-be-configured cell of each inter-frequency adjacent cell from the PCI candidate list.

进一步的,S60包括:获取所述PCI候选列表中剩余的各个候选PCI对预设参数的第一取模结果;获取所述同频邻区的PCI对所述预设参数的第二取模结果;从所述PCI候选列表中过滤所述第一取模结果与所述第二取模结果相同的PCI。其中,预设参数包括3、4和30。Further, S60 includes: acquiring a first modulo result of each remaining candidate PCI in the PCI candidate list to a preset parameter; acquiring a second modulo result of the preset parameter by the PCI of the same-frequency adjacent area ; filter the PCIs whose first modulo result is the same as the second modulo result from the PCI candidate list. Among them, the preset parameters include 3, 4 and 30.

由于,在待配置小区的PCI和同频邻区PCI对3取模结果相同时,会影响终端接收主同步信号(PSS,Primary Synchronization Signal),因此,可以对所述PCI候选列表中剩余的各个候选PCI进行第一模运算,所述第一模运算为候选PCI对3取模;对所述邻区PCI进行第一模运算;从所述PCI候选列表中过滤所述第一模运算结果相同的候选PCI。Because, when the PCI of the cell to be configured and the PCI of the same-frequency neighboring cell are the same as the result of modulo 3, it will affect the terminal to receive the Primary Synchronization Signal (PSS, Primary Synchronization Signal). The first modulo operation is performed on the candidate PCI, and the first modulo operation is that the candidate PCI is modulo 3; the first modulo operation is performed on the adjacent area PCI; the result of filtering the first modulo operation from the PCI candidate list is the same candidate PCI.

由于,在待配置小区的PCI和同频邻区PCI对4取模结果相同时,会造成物理广播信道(PBCH)的解调参考信号(DMRS,DeModulation Reference Signal)干扰,因此,可以对所述PCI候选列表中剩余的各个候选PCI进行第二模运算,所述第二模运算为候选PCI对4取模;对所述邻区PCI进行第二模运算;从所述PCI候选列表中过滤所述第二模运算结果相同的候选PCI。Since, when the PCI of the cell to be configured and the PCI of the same-frequency neighboring cell are the same as the result of modulo 4, the demodulation reference signal (DMRS, DeModulation Reference Signal) of the physical broadcast channel (PBCH) will be interfered. Each remaining candidate PCI in the PCI candidate list is subjected to a second modulo operation, where the second modulo operation is the candidate PCI to modulo 4; the second modulo operation is performed on the adjacent PCI; candidate PCIs with the same result of the second modulo operation.

由于,在待配置小区的PCI和同频邻区PCI对30取模结果相同时,会造成上行物理控制信道(PUCCH)和上行物理共享信道(PUSCH)的解调参考信号干扰,也会造成探测参考信号(SRS,Sounding Reference Signal)干扰,因此,可以对所述PCI候选列表中剩余的各个候选PCI进行第三模运算,所述第三模运算为候选PCI对30取模;对所述邻区PCI进行第三模运算;从所述PCI候选列表中过滤所述第三模运算结果相同的候选PCI。Because, when the PCI of the to-be-configured cell and the PCI of the same-frequency adjacent cell have the same result of modulo 30, the demodulation reference signal interference of the uplink physical control channel (PUCCH) and uplink physical shared channel (PUSCH) will be caused, and the detection will also be caused. Reference signal (SRS, Sounding Reference Signal) interference, therefore, the third modulo operation can be performed on each remaining candidate PCI in the PCI candidate list, and the third modulo operation is the candidate PCI pair 30 modulo; A third modulo operation is performed on the zone PCI; candidate PCIs with the same result of the third modulo operation are filtered from the PCI candidate list.

示范性的,在待配置小区的同频邻区PCI为7,对3取模结果为1时,则从PCI候选列表中剩余的各个候选PCI中过滤对3取模结果为1的候选PCI。Exemplarily, when the PCI of the same-frequency neighboring cell of the to-be-configured cell is 7, and the result of modulo 3 is 1, the candidate PCI whose modulo 3 result is 1 is filtered from the remaining candidate PCIs in the PCI candidate list.
