Description

一种实现频谱干扰处理的方法、GSM基站及LTE基站Method for realizing spectrum interference processing, GSM base station and LTE base station 技术领域Technical field
本申请涉及但不限于无线通信技术。This application relates to, but is not limited to, wireless communication technologies.
背景技术Background technique
随着无线通信技术的迅速发展和无线通信业务的不断丰富，大量的无线通信设备在长期演进(LTE)频谱资源上使用无线通信业务，使LTE系统的频谱资源日趋紧张，而随着GSM系统的用户的不断减少，GSM系统的频谱出现较多的空闲，为了满足市场的需求，运营商正在从根本上改变他们利用已有频谱的方式，频谱重整(spectrum reforming)便是其中一种。With the rapid development of wireless communication technologies and the enrichment of wireless communication services, a large number of wireless communication devices use wireless communication services on Long Term Evolution (LTE) spectrum resources, making the spectrum resources of LTE systems increasingly tight, and with the GSM system With the continuous reduction of users, the spectrum of the GSM system appears more idle. In order to meet the needs of the market, operators are fundamentally changing the way they use existing spectrum, and spectrum reforming is one of them.
频谱重整是解决业务需求指数增长与频谱资源有限之间的矛盾的一种方式，利用频谱重整可以提升频谱的利用效率和灵活性，将GSM系统空闲的频谱资源借给能提供更高数据传输速率的LTE系统，包括有以下几种实现方式：1)将GSM系统的下行空闲频谱借给LTE频分复用(FDD)下行，将GSM系统的上行空闲频谱借给LTE FDD上行；2)将GSM系统的下行空闲频谱借给时分LTE(TD-LTE)；3)将GSM系统的上行空闲频谱借给TD-LTE；4)将GSM系统的上下行空闲频谱借给TD-LTE。由此可以看出GSM系统的上行空闲频谱可以借给LTE FDD上行，也可以借给TD-LTE。Spectrum re-routing is a way to solve the contradiction between the exponential growth of service demand and the limited spectrum resources. Spectrum re-use can improve the efficiency and flexibility of spectrum utilization, and lend the idle spectrum resources of the GSM system to provide higher data. The LTE system with the transmission rate includes the following implementation modes: 1) lending the downlink idle spectrum of the GSM system to the LTE frequency division multiplexing (FDD) downlink, and lending the uplink idle spectrum of the GSM system to the LTE FDD uplink; 2) Lending the downlink idle spectrum of the GSM system to time division LTE (TD-LTE); 3) lending the uplink idle spectrum of the GSM system to TD-LTE; 4) lending the uplink and downlink idle spectrum of the GSM system to TD-LTE. It can be seen that the uplink idle spectrum of the GSM system can be borrowed for LTE FDD uplink or TD-LTE.
由于GSM系统用户分布的不均匀性，可能一个区域的GSM频谱空闲，而另一个区域的GSM频谱不空闲。图1是相关技术GSM频谱空闲不均匀的示意图，如图1所示，假设890～900MHz是区域A和区域B中GSM系统的频谱，在区域A中，由于GSM系统用户数大量减少，GSM系统频谱中的895～900MHz的5MHz频谱逐渐空闲；而区域B中GSM系统用户数变化较少，因此区域B中的GSM系统频谱不空闲。当GSM系统的上行空闲频谱895～900MHz借给区域A中靠近区域B的LTE FDD小区A上行使用时，与区域B中靠近区域A的GSM小区B的上行频点中的898MHz恰好交叠，由于GSM系统的信号功率谱密度远远大于LTE的信号功率谱密度，因此GSM小区B的上行可能对LTE FDD小区A的上行产生严重干扰；图中实线表示 有用信号，虚线表示干扰信号。同样，当GSM系统的上行空闲频谱895～900MHz借给区域A中靠近区域B的TD-LTE小区A使用时，GSM小区B的上行也会对TD-LTE小区A产生严重干扰。Due to the non-uniformity of the GSM system user distribution, it is possible that the GSM spectrum of one area is idle while the GSM spectrum of another area is not idle. 1 is a schematic diagram of the GSM spectrum idleness unevenness of the related art. As shown in FIG. 1, it is assumed that 890 to 900 MHz is the spectrum of the GSM system in the area A and the area B. In the area A, the GSM system is greatly reduced due to the large number of users of the GSM system. The 5MHz spectrum of 895-900MHz in the spectrum is gradually idle; while the number of GSM system users in area B changes less, so the spectrum of the GSM system in area B is not idle. When the uplink idle spectrum of the GSM system is 895-900 MHz and is used for uplink use of the LTE FDD cell A in the area A near the area B, it overlaps with 898 MHz in the uplink frequency point of the GSM cell B in the area B close to the area A, due to The signal power spectral density of the GSM system is much larger than the signal power spectral density of LTE, so the uplink of the GSM cell B may cause serious interference to the uplink of the LTE FDD cell A; the solid line in the figure indicates Useful signals, dashed lines indicate interference signals. Similarly, when the uplink idle spectrum of the GSM system is 895-900 MHz and is used by the TD-LTE cell A in the area A near the area B, the uplink of the GSM cell B may also cause serious interference to the TD-LTE cell A.
相关技术中，对干扰进行处理的方法是通过在区域A和区域B之间规划一个缓冲带(buffer zone)，在缓冲带内设置GSM系统和LTE系统都不能使用GSM系统的上行空闲频谱。该方案虽然解决了上行干扰问题，但存在频谱资源的浪费。In the related art, the method of processing interference is to plan a buffer zone between the area A and the area B, and the GSM system and the LTE system in the buffer zone cannot use the uplink idle spectrum of the GSM system. Although this solution solves the problem of uplink interference, there is a waste of spectrum resources.

以下通过实施例对本申请进行清楚详细的说明。由于在GSM系统频谱重整过程中，GSM小区的广播控制信道BCCH(Broadcast control channel)用于提供连续覆盖，因此GSM小区的BCCH频谱不会借给LTE小区，仅仅将空闲的业务信道TCH(Traffic Channel)频谱借给LTE小区使用。以下实施例都是基于这一事实。The present application will be described in detail below by way of examples. Since the broadcast control channel BCCH (Broadcast Control Channel) of the GSM cell is used to provide continuous coverage during the spectrum re-routing process of the GSM system, the BCCH spectrum of the GSM cell is not lent to the LTE cell, and only the idle traffic channel TCH (Traffic) Channel) The spectrum is borrowed for use by the LTE cell. The following examples are based on this fact.
在实施例中以eNB(Evolved Node B)作为LTE基站，频谱带宽为5MHz，频率范围为895MHz到900MHz。In the embodiment, an eNB (Evolved Node B) is used as an LTE base station, and the spectrum bandwidth is 5 MHz, and the frequency range is 895 MHz to 900 MHz.
实施例1Example 1
图6是本发明第一实施例发送被干扰指示信息的交互示意图，其中，LTE系统和GSM系统的核心网网元分别为移动管理实体(Mobility Management Entity，MME)和GPRS服务支持节点(Serving GPRS Support Node，SGSN)。如图6所示，包括：6 is a schematic diagram of interaction of transmitting interference indication information according to the first embodiment of the present invention, wherein the core network elements of the LTE system and the GSM system are respectively a Mobility Management Entity (MME) and a GPRS service support node (Serving GPRS). Support Node, SGSN). As shown in Figure 6, it includes:
步骤600、eNB发送被干扰指示信息给GSM基站控制器(BSC)；转发过程包括eNB向MME发送被干扰指示信息，MME将该信息转发给SGSN，SGSN再转发给BSC；Step 600: The eNB sends the interference indication information to the GSM base station controller (BSC). The forwarding process includes the eNB transmitting the interference indication information to the MME, and the MME forwards the information to the SGSN, and the SGSN forwards the information to the BSC.
eNB在发送被干扰指示信息之前，根据小区当前工作频段上行接收的信号质量情况(例如物理资源块的上行信号噪声比)或者物理资源块的上行信号功率大小，可确定上行受干扰的小区以及受干扰频率范围。 Before transmitting the interfered indication information, the eNB may determine the uplink interfered cell and the received signal quality according to the uplink signal quality of the current working frequency band of the cell (for example, the uplink signal to noise ratio of the physical resource block) or the uplink signal power of the physical resource block. Interference frequency range.
被干扰指示信息假设包括：受干扰频率范围为897.77MHz到898.13MHz，受干扰小区位置为(东经43度，北纬56度)。The interference indication information hypothesis includes: the interference frequency range is 897.77MHz to 898.13MHz, and the location of the interfered cell is (43 degrees east longitude, 56 degrees north latitude).
步骤601、BSC接收到被干扰指示信息之后，确定产生干扰的GSM小区及产生干扰的频点，进行干扰处理。Step 601: After receiving the interference indication information, the BSC determines the GSM cell that generates the interference and the frequency of the interference, and performs interference processing.
在受干扰频率范围内，有两个GSM的频点，其ARFCN分别为39和40，对应的中心频率分别为897.8MHz和898MHz，其中897.8MHz频点不是BSC下属GSM小区的工作频点，将该频点排除，因此产生干扰的频点是898MHz，然后确定其管辖范围内使用898MHz频点，且距离受干扰小区位置最近的GSM小区的小区全球标识，确定结果为GSM小区CGI2为干扰源小区。In the frequency range of interference, there are two GSM frequency points, the ARFCN is 39 and 40 respectively, and the corresponding center frequencies are 897.8MHz and 898MHz, respectively. The 897.8MHz frequency point is not the working frequency of the GSM cell under the BSC. The frequency point is excluded, so the frequency of the interference is 898 MHz, and then the cell global identifier of the GSM cell using the 898 MHz frequency point and closest to the location of the victim cell is determined, and the result is that the GSM cell CGI2 is the interference source cell. .
BSC结合CGI2当前的负载情况，CGI2小区的负载不太重，决定将898MHz频点从CGI2小区的频点集合中删除，即不让CGI2小区使用该频点，以免对LTE小区产生上行干扰。The BSC combines the current load situation of CGI2, and the load of the CGI2 cell is not too heavy. It is decided to remove the 898MHz frequency point from the frequency point set of the CGI2 cell, that is, the CGI2 cell is not allowed to use the frequency point, so as to avoid uplink interference to the LTE cell.
步骤602、BSC将干扰处理的响应消息发送给eNB，其中转发过程包括：BSC将干扰处理的响应消息发送给SGSN，SGSN将该消息转发给MME，MME再转发给eNB。Step 602: The BSC sends the response message of the interference processing to the eNB, where the forwarding process includes: the BSC sends the response message of the interference processing to the SGSN, and the SGSN forwards the message to the MME, and the MME forwards the message to the eNB.
响应消息包括是否采取操作的标识为1，即采取操作，以及操作的标识为2，即采取的操作为删除产生干扰的频点。The response message includes whether the identifier of the operation is taken as 1, that is, the operation is taken, and the identifier of the operation is 2, that is, the operation taken is to delete the frequency point at which the interference occurs.
值得说明的是：上述删除898MHz频点是可选操作，BSC也可以不采取任何措施。另外BSC也可以根据实际情况，自己决定CGI2小区用户设备的功率调整量，对CGI2小区用户设备进行功率控制，例如以0.5dB为调整量，降低CGI2小区用户设备的发射功率，或者BSC让CGI2小区的基站BTS(Base Transceiver Station)在产生干扰的频点898MHz上仅调度位于CGI2小区中心的用户设备，需要注意的是响应消息需要根据采取的操作进行相应的变化。It is worth noting that the above deletion of the 898MHz frequency point is optional, and the BSC can take no action. In addition, the BSC can also determine the power adjustment amount of the CGI2 cell user equipment according to the actual situation, and perform power control on the CGI2 cell user equipment, for example, 0.5 dB as the adjustment amount, and reduce the transmission power of the CGI2 cell user equipment, or the BSC allows the CGI2 cell to be used. The base station BTS (Base Transceiver Station) only schedules the user equipment located at the center of the CGI2 cell at the frequency of the interference generated at 898 MHz. It should be noted that the response message needs to be changed according to the operation taken.
另外，当LTE系统采用其他的核心网网元(例如S-GW(Serving Gateway))时，被干扰指示信息传递的路径为：eNB->S-GW->SGSN->BSC，响应消息的传递路径与之相反。 In addition, when the LTE system adopts other core network elements (for example, S-GW (Serving Gateway)), the path of the interference indication information transmission is: eNB->S-GW->SGSN->BSC, and the response message is transmitted. The path is the opposite.
本实施例中受干扰频率范围为897.77MHz到898.13MHz，是以起始频率和终止频率表示的，受干扰频率范围也可以用LTE小区的中心频点及受干扰的物理资源块PRB编号来表示，这时受干扰频率范围为：中心频点为987.5MHz，受干扰的PRB编号为：15和16。BSC收到被干扰指示信息之后根据GSM频点与LTE小区PRB的对应关系确定产生干扰的GSM频点，其它步骤不用改变。In this embodiment, the interference frequency range is 897.77 MHz to 898.13 MHz, which is represented by the starting frequency and the ending frequency. The interfered frequency range can also be represented by the center frequency of the LTE cell and the interfered physical resource block PRB number. At this time, the interference frequency range is: the center frequency is 987.5MHz, and the interfered PRB numbers are: 15 and 16. After receiving the interference indication information, the BSC determines the GSM frequency point that generates interference according to the correspondence between the GSM frequency point and the LTE cell PRB, and the other steps do not need to be changed.
实施例2Example 2
图7是本发明第二实施例发送被干扰指示信息的交互示意图，其中，LTE系统的网管网元为网元管理系统1(Element Management System，EMS)和网络管理系统1(Network Management System，NMS),GSM系统的网管网元为EMS2和NMS2，如图7所示，包括：FIG. 7 is a schematic diagram of interaction of transmitting interference indication information according to a second embodiment of the present invention. The network management network element of the LTE system is an Element Management System (EMS) and a Network Management System (NMS). The network management network elements of the GSM system are EMS2 and NMS2, as shown in Figure 7, including:
步骤700、eNB将被干扰指示信息发送给BSC，被干扰指示信息发送过程中经过EMS1、NMS1、NMS2、EMS2；Step 700, the eNB sends the interference indication information to the BSC, and the EMS1, NMS1, NMS2, and EMS2 are transmitted during the transmission of the interference indication information;
eNB在发送被干扰指示信息之前，根据小区当前工作频段上行IoT(Interference over Thermal noise)信息，确定受干扰的频率范围为895.97MHz到896.15MHz，即第5个物理资源块受到严重干扰。在此频率范围内的GSM频点为896MHz频点，对应的ARFCN为30；根据受干扰频段当前的干扰噪声比IoT，以及期望的IoT，决定将受干扰频段当前IoT降低2dB，因此建议GSM用户设备功率调整量为2dB。Before transmitting the interfered indication information, the eNB determines that the interfered frequency range is 895.97 MHz to 896.15 MHz according to the uplink IoT (Interference over Thermal Noise) information of the current working frequency band of the cell, that is, the fifth physical resource block is seriously interfered. The GSM frequency in this frequency range is 896MHz, and the corresponding ARFCN is 30. According to the current interference-to-noise ratio IoT of the interfered band and the expected IoT, it is decided to reduce the current IoT of the interfered band by 2dB. Therefore, it is recommended that GSM users The device power adjustment is 2dB.
本实施例，被干扰指示信息包括：受干扰小区位置为(东经43度，北纬50度)，产生干扰的GSM频点的ARFCN为30和建议GSM用户设备功率调整量为2dB。In this embodiment, the interfered indication information includes: the location of the interfered cell is (43 degrees east longitude, 50 degrees north latitude), the ARFCN of the GSM frequency point that generates interference is 30, and the power adjustment amount of the recommended GSM user equipment is 2 dB.
步骤701、BSC接收到被干扰指示信息之后，确定产生干扰的GSM小区，并采取相应干扰处理操作。Step 701: After receiving the interfered indication information, the BSC determines the GSM cell that generates the interference, and takes a corresponding interference processing operation.
BSC根据使用ARFCN为30的频点的GSM小区的位置，以及受干扰小区位置确定产生干扰的GSM小区为CGI3，即CGI3为干扰源小区。BSC根据建议的GSM用户设备功率调整量对用户设备进行功率控制，即将CGI3小区使用ARFCN为30的频点的用户设备的发射功率减小2dB，以免对LTE小 区产生上行干扰。The BSC determines that the GSM cell that generates interference according to the location of the GSM cell using the frequency of the ARFCN of 30 and the location of the interfered cell is CGI3, that is, CGI3 is the interference source cell. The BSC performs power control on the user equipment according to the recommended power adjustment amount of the GSM user equipment, that is, the transmission power of the user equipment of the CGI3 cell using the ARFCN frequency of 30 is reduced by 2 dB, so as to avoid small LTE. The area generates uplink interference.
步骤702、BSC将干扰处理的响应消息发送给eNB，响应消息经过EMS2、NMS2、NMS1、EMS1依次转发后发送给eNB。Step 702: The BSC sends the response message of the interference processing to the eNB, and the response message is sequentially forwarded by the EMS2, the NMS2, the NMS1, and the EMS1, and then sent to the eNB.
响应消息包括操作的标识为1，即采取的操作为功率控制。The response message includes the identifier of the operation being 1, that is, the operation taken is power control.
上述功率控制是可选操作，也就是说被干扰指示信息也可以不包含建议GSM用户设备功率调整量，这时BSC可以根据CGI3的当前负载情况，进行其它的操作：例如，如果CGI3负载较轻，BSC可以删除CGI3的ARFCN为30的频点，如果CGI3的负载较重，BSC可以不采取任何措施，这时eNB可以采用其它的方法来避开CGI3小区的干扰，比如在受干扰频段上不调度用户设备或仅调度小区中心的用户设备，或者BSC让GSM基站在产生干扰的频点898MHz上仅调度位于CGI2小区中心的用户设备，需要注意的是响应消息需要根据采取的操作进行相应的变化。The above power control is optional, that is, the interfered indication information may not include the recommended GSM user equipment power adjustment amount. At this time, the BSC may perform other operations according to the current load condition of the CGI3: for example, if the CGI3 load is light The BSC can delete the frequency of the ARFCN of the CGI3 to 30. If the load of the CGI3 is heavy, the BSC can take no measures. At this time, the eNB can adopt other methods to avoid the interference of the CGI3 cell, for example, in the interfered frequency band. The user equipment is scheduled or only the user equipment of the cell center is scheduled, or the BSC allows the GSM base station to schedule only the user equipment located in the cell center of the CGI2 at the frequency of the interference generation 898 MHz. It should be noted that the response message needs to be changed according to the operation taken. .
另外，当LTE和GSM系统归属于同一个NMS时，被干扰指示信息传递的路径为：eNB->LTE的EMS->NMS(两系统共同的NMS)->GSM的EMS->BSC；In addition, when the LTE and the GSM system belong to the same NMS, the path of the interference indication information transmission is: eNB->EMS->NMS of LTE (NMS common to both systems)->EMS->BSC of GSM;
当LTE和GSM系统归属于同一个EMS时，被干扰指示信息传递也可以不通过NMS，路径为：eNB->EMS(两系统共同的EMS)->BSC；When the LTE and the GSM system belong to the same EMS, the interference indication information transmission may not pass through the NMS, and the path is: eNB->EMS (EMS common to both systems)->BSC;
当LTE和GSM系统的EMS间存在接口时，被干扰指示信息传递也可以不通过NMS，路径为：eNB->LTE的EMS->GSM的EMS->BSC；When there is an interface between the EMS of the LTE and the GSM system, the interference indication information transmission may not pass through the NMS, and the path is: eNB->EMS of the LTE->EMS->BSC of the GSM;
响应消息的传递路径与被干扰指示信息的传递路径正好相反。The delivery path of the response message is exactly the opposite of the delivery path of the interfered indication information.

The eNB learns the neighboring GSM cell CGI3 according to the neighbor relationship list. The 896MHz frequency is just within the interference frequency range.

步骤801、BSC接收到被干扰指示信息之后，进行相应干扰处理。Step 801: After receiving the interfered indication information, the BSC performs corresponding interference processing.
BSC根据被干扰指示信息，确定让BTS在产生干扰的频点896MHz上仅调度位于CGI3小区中心的用户设备，从而减小了CGI3小区对LTE小区的上行干扰。Based on the interfered indication information, the BSC determines that the BTS only schedules the user equipment located at the center of the CGI3 cell at the frequency of the interference 896 MHz, thereby reducing the uplink interference of the CGI3 cell to the LTE cell.
步骤802、BSC向eNB发送干扰处理的响应消息。Step 802: The BSC sends a response message of the interference processing to the eNB.
响应消息包括是否采取操作的标识为1，即采取操作。The response message includes whether the identity of the action taken is 1, that is, the operation is taken.
值得说明的是：上述干扰处理方法是可选操作，也就是说BSC也可以根据CGI3的当前负载情况，进行其它的操作：例如，如果CGI3负载较轻，BSC可以删除CGI3的896MHz频点，如果CGI3的负载较重，BSC可以不采取任何措施，这时eNB可以采用其它的方法来避开CGI3小区的干扰，比如在受干扰频段上不调度用户设备，需要注意的是响应消息需要根据采取的操作进行相应的变化。It is worth noting that the above interference processing method is optional, that is to say, the BSC can also perform other operations according to the current load situation of the CGI3: for example, if the CGI3 load is light, the BSC can delete the 896 MHz frequency of the CGI3, if The load of CGI3 is heavy, and the BSC can take no measures. At this time, the eNB can adopt other methods to avoid the interference of the CGI3 cell. For example, the user equipment is not scheduled in the interfered frequency band, and it should be noted that the response message needs to be taken according to the The operation changes accordingly.

图10是本发明第五实施例发送被干扰指示信息的交互示意图，如图10所示，包括：FIG. 10 is a schematic diagram of interaction of transmitting interference indication information according to a fifth embodiment of the present invention. As shown in FIG. 10, the method includes:
步骤1000、eNB向BSC发送被干扰指示信息；Step 1000: The eNB sends the interfered indication information to the BSC.
其中，被干扰指示信息包括上行高干扰指示HII为(0000100000000010000000000)，即第5、15个物理资源块为高干扰灵敏资源块，受干扰小区位置为(东经43度，北纬50度)。The interference indication information includes an uplink high interference indication HII (0000100000000010000000000), that is, the 5th and 15th physical resource blocks are high interference sensitive resource blocks, and the location of the interfered cell is 43 degrees east longitude and 50 degrees north latitude.
步骤1001，BSC接收到被干扰指示信息之后，进行相应的干扰处理。Step 1001: After receiving the interfered indication information, the BSC performs corresponding interference processing.
BSC根据被干扰指示信息中的HII信息，以及高干扰灵敏资源块与频段的对应关系，从而确定产生干扰的GSM频点，以第5个物理资源块为例，第5个物理资源块对应的频段范围为895.97MHz到896.15MHz，在此频率范围内的GSM频点为896MHz频点，对应的ARFCN为30，同理可以得到可能对第15个物理资源块产生干扰的GSM频点为897.8MHz，对应的ARFCN为39。The BSC determines the GSM frequency point that generates the interference according to the HII information in the interfered indication information and the correspondence between the high interference sensitive resource block and the frequency band, and takes the fifth physical resource block as an example, and the fifth physical resource block corresponds to the fifth physical resource block. The frequency range is 895.97MHz to 896.15MHz. The GSM frequency in this frequency range is 896MHz, and the corresponding ARFCN is 30. Similarly, the GSM frequency that may interfere with the 15th physical resource block is 897.8MHz. The corresponding ARFCN is 39.
然后确定其管辖范围内使用896MHz和897.8MHz频点，且与受干扰LTE小区位置相邻的GSM小区，确定结果为GSM小区CGI2和CGI3为干扰源小区。Then, the GSM cell in the jurisdiction that uses the 896 MHz and 897.8 MHz frequency points and is adjacent to the interfered LTE cell location is determined, and the result is that the GSM cells CGI2 and CGI3 are the interference source cells.
BSC结合CGI2和CGI3当前的负载情况，两个小区的负载不太重，决定将898MHz和897.8MHz频点分别从CGI2和CGI3小区的频点集合中删除，以免对LTE小区产生上行干扰。The BSC combines the current load conditions of CGI2 and CGI3. The load of the two cells is not too heavy. It is decided to remove the 898MHz and 897.8MHz frequency points from the frequency set of the CGI2 and CGI3 cells respectively to avoid uplink interference to the LTE cell.
步骤1002、BSC向eNB发送干扰处理的响应消息。Step 1002: The BSC sends a response message of the interference processing to the eNB.
响应消息包括是否采取操作的标识为1，即采取操作。以及操作的标识 为2，即采取的操作为删除可能产生干扰的频点。The response message includes whether the identity of the action taken is 1, that is, the operation is taken. And the identity of the operation At 2, the action taken is to remove the frequency points that may cause interference.
值得说明的是：1)上述删除产生干扰的频点是可选操作，也就是说BSC也可以采取其它操作如对这两个频点上调度的用户设备进行功率控制，或者在产生干扰的GSM频点上仅调度位于GSM小区中心的用户设备，或者不采取任何操作；2)被干扰指示信息包括上行过载指示OI和受干扰小区位置时的干扰协调方法与此类似，对OI中高干扰的物理资源块采取与高干扰灵敏资源块类似的操作即可；3)本实施例也可以通过核心网网元、网管网元、集中式控制节点等传输被干扰指示信息。It is worth noting that: 1) The above-mentioned frequency of interference generation is optional, that is to say, the BSC can also take other operations such as power control of the user equipment scheduled at the two frequency points, or GSM in which interference occurs.
