Technical Field

[0001] The embodiments of the present application relate to the field of communications, and specifically to an information processing method and related equipment. Background Art

[0002] Spectrum sharing between LTE and 5G NR new radio is a technology that can quickly introduce 5G on existing LTE spectrum and expand LTE on new 5G spectrum, which can effectively improve spectrum utilization.

[0003] LTE and NR spectrum sharing can share channels according to the real-time business needs of LTE and NR. In spectrum sharing, there will be problems of channel interference between LTE and NR systems. For example, when LTE sends a reference signal, it needs to occupy the frequency domain resources on LTE. If NR and LTE are shared frequency domain resources, then when the NR side sends a message on the same frequency domain resource, mutual interference will occur, affecting the sending quality of the NR message. Summary of the invention

[0004] The embodiments of the present application provide an information processing method and related equipment for eliminating interference signals when sending NR messages, thereby improving the transmission quality of NR messages sent by a base station.

[0005] A first aspect of an embodiment of the present application provides an information processing method, including:

[0006] The base station obtains the time-frequency resources required for the first wireless access technology to send the target message, and the time-frequency resources are determined by the base station receiving the target message. When the first wireless access technology and the second wireless access technology are applied to the same base station, the base station receives the target message and obtains the time-frequency resources for sending the target message through the first wireless access technology according to the target message. After the base station obtains the time-frequency resources, it eliminates the interference signal to be sent on the time-frequency resources through the second wireless access technology, and then sends the target message through the first wireless access technology on the bandwidth corresponding to the time-frequency resources.

[0007] When the first wireless access technology and the second wireless access technology are respectively applied to different base stations, the base station applying the first wireless access technology receives the target message, and after confirming the time-frequency resources according to the target message, sends the confirmation result to the base station of the second wireless access technology, and the base station of the second wireless access technology obtains the time-frequency resources required to send the target message through the first wireless access technology. After the base station of the second wireless access technology obtains the time-frequency resources, the interference signal to be sent on the time-frequency resources through the second wireless access technology is eliminated, and then the base station of the first wireless access technology can send the target message through the first wireless access technology on the bandwidth corresponding to the time-frequency resources.

[0008] In an embodiment of the present application, the base station eliminates the interference signal of the bandwidth corresponding to the time-frequency resources required for the base station to send the target message, and sends the target message through the bandwidth corresponding to the time-frequency resources, so that no interference will be generated, thereby improving the transmission quality of the base station sending the target message to the terminal.

[0009] Optionally, in a possible implementation manner, the receiver of the target message does not support rate matching RM, and the receiver is determined by the base station through the target message.

[0010] In the embodiment of the present application, only the target message that does not support the rate matching RM mode is sent in the bandwidth that eliminates the interference signal, thereby improving the utilization rate of the network.

[0011] Optionally, in a possible implementation, the target message acquired by the base station is a cell-level message, that is, the target message is generated by the base station and used to be sent to terminals in the cell, and the message includes: a system broadcast message and an initial configuration message.

[0012] Optionally, in a possible implementation manner, before the base station is ready to send a target message to a first terminal in a cell, the first terminal sends capability information to the base station, where the capability information indicates that the first terminal does not support receiving the target information in a rate matching RM manner.

[0013] Optionally, in a possible implementation, before the base station prepares to send a target message to the first terminal in the cell, the first terminal does not send capability information to the base station, and the capability information indicates whether the first terminal supports receiving the target information in a rate-matched RM manner. The base station determines that it cannot send the target message to the first terminal in a rate-matched manner.

[0014] In the embodiment of the present application, the base station sends several target messages that do not support the rate matching RM method in a bandwidth that eliminates interference signals, thereby avoiding the problem of target messages that do not support the rate matching RM sending method being interfered with by interference signals, and improving the transmission quality of the target messages transmitted by the base station.

[0015] Optionally, in a possible implementation, before the base station completes the wireless resource control RRC configuration with the first terminal in the cell, the base station will not receive capability information from the first terminal, and the capability information indicates whether the first terminal supports receiving target information in a rate matching RM manner. The base station determines that it cannot send the target message to the first terminal in a rate matching manner.

[0016] In an embodiment of the present application, the base station determines that the terminal before completing the wireless resource control RRC configuration does not support the rate matching RM method to receive the target information, and then sends the target information in a bandwidth that eliminates the interference signal, thereby avoiding the problem of the target message that does not support the rate matching RM sending method being interfered by the interference signal, and improving the transmission quality of the target message transmitted by the base station.

[0017] Optionally, in a possible implementation, the base station eliminates the interference signal to be sent on the bandwidth corresponding to the time-frequency resource through the second radio access technology by sending a cancellation signal.

[0020] In the embodiment of the present application, the base station determines the time-frequency resources according to the information volume data and the channel quality, thereby improving the feasibility of the solution.

[0021] Optionally, in a possible implementation, the base station eliminates the interference signal to be sent on the bandwidth corresponding to the time-frequency resource through the second radio access technology in a silent manner, that is, adjusts the transmission power of the interference signal to be sent to zero.

[0022] In the embodiment of the present application, the base station eliminates the interference signal to be sent on the bandwidth corresponding to the time-frequency resource through the second wireless access technology in a silent manner, thereby improving the feasibility of the solution.

[0023] Optionally, in a possible implementation, the first wireless access technology may be a new radio interface NR wireless access technology, and the second wireless access technology may be a long term evolution LTE wireless access technology.

[0026] In the embodiment of the present application, when the interference signal is a cell-specific reference signal CRS, the feasibility of the solution is improved.

[0027] Optionally, in a possible implementation manner, the interference signal may be a signal sent in a physical downlink control channel PDCCH channel.

[0028] In the embodiment of the present application, when the interference signal is a signal sent in a physical downlink control channel PDCCH channel, the feasibility of the solution is improved.

[0029] Optionally, in a possible implementation manner, the interference signal may be a signal sent in a Physical Hybrid Automatic Repeat Indicator Channel PHICH channel.

[0030] In the embodiment of the present application, when the interference signal is a signal sent in a physical hybrid automatic repeat indicator channel PHICH channel, the feasibility of the solution is improved.

[0031] Optionally, in a possible implementation, the interference signal may be a signal sent in a physical control format indicator channel PCFICH channel.

[0068] An embodiment of the present application provides an information processing method, which is used to eliminate the interference signal of the bandwidth corresponding to the frequency domain resources required by the target message when the NR and LTE spectrums are shared, and send the target message through the frequency domain resources, so that when the base station sends the NR message again, it will not be interfered by the reference signal of LTE on the same frequency domain resources, thereby improving the sending quality of the NR message sent by the base station.

[0069] Please combine Figure 1 In the embodiment of the present application, the communication system framework includes:

[0070] The embodiment of the present application provides a communication system, which includes at least one base station 102 and at least one terminal 103. The one or more base stations are connected to the core network 101, and the one or more terminals can communicate with the at least one or more base stations. It should be noted that the base station and terminal included in the communication system are only an example. In the embodiment of the present application, the type and number of network elements included in the communication system, and the connection relationship between network elements are not limited thereto.

[0071] The communication system in the embodiment of the present application may be a communication system supporting the fourth generation access technology (fourth generation, 4G), such as long term evolution (long term evolution, LTE) access technology; or, the communication system may also be a communication system supporting the third generation (third generation, 3G) access technology, such as universal mobile telecommunications system (universal mobile telecommunications system, UMTS) access technology; or, the communication system may also be a communication system supporting the fifth generation (fifth generation, 5G) access technology, such as new air interface access technology (newradia, NR); or, the communication system may also be a communication system supporting multiple wireless access technologies, such as a communication system supporting LTE technology and NR technology. It is understandable that the communication system may also be applicable to future-oriented communication technologies, such as communication systems for wireless access technologies such as 6G, 7G, etc., which are not specifically limited here.

[0072] The base station in the embodiment of the present application can be a device on the access network side used to support terminal access to the communication system, for example, an evolved base station (evolved nodeB, eNB) in a 4G access technology communication system, a next generation base station (next generation nodeB, gNB) in a 5G access technology communication system, and so on.

[0073] The terminal in the embodiment of the present application may be a device that provides voice or data connectivity to a user, and may also be referred to as user equipment (UE), mobile station, subscriber unit, station, terminal equipment (TE), etc. For example, the terminal may be a cellular phone, a personal digital assistant (PDA), a wireless modem, a handheld device (handheld), a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer (pad), etc. With the development of wireless communication technology, devices that can access a communication system, communicate with the network side of a communication system, or communicate with other objects through a communication system, power meter reading instruments in smart grid equipment, voltage detection instruments, environmental detection instruments, video surveillance instruments in smart security networks, cash registers, etc.

[0074] For cells of different network standards, spectrum utilization can be improved through spectrum sharing. For example, when LTE cells and NR cells share spectrum, if the coverage areas of LTE cells and NR cells correspond one to one, part of the spectrum resources of an LTE cell can be shared with the corresponding NR cell, thereby improving spectrum utilization. LTE and NR spectrum sharing can be performed according to the real-time service needs of LTE and NR, and can achieve dynamic spectrum sharing at the millisecond level in the time domain and at the frequency domain resource block (RB) level in the frequency domain. For example, when the base station needs to send a 5RB NR message, the NR message can be sent in the 5RB frequency domain resources under the corresponding subframe in the shared spectrum of LTE and NR. It should be noted that in the 5G environment, the frequency domain bandwidth of the subcarrier spacing on the NR side can be 15Khz, 30KHz, 60KHz, etc. When the frequency domain bandwidth of the subcarrier spacing (SCS) on the NR side is 30Khz, that is, 1RB=12scs=360Khz, the frequency domain resources required for the NR side to send messages are 5RB=60SCS=1800Khz, and the time-frequency resources that need to be shared on the LTE side are 1800Khz=120SCS=10RB. Similarly, when the frequency domain bandwidth of the subcarrier spacing on the NR side is 60Khz, the NR side sends a 5RB message, and the frequency domain resources that need to be shared on the LTE side are 20RB. In actual application, the frequency domain resource RB can be converted according to the specific situation. The specific details are not limited here. The embodiment of the present application is described as an example of the subcarrier spacing set by the NR base station being 15Khz.

[0075] It is understandable that the specific application scenarios in the embodiments of the present application are not limited to dynamic spectrum sharing at the ms level and RB level. For example, there are more subdivided application scenarios in the subsequent 6G or 7G fields, which are not specifically limited here.

[0076] To facilitate understanding of this embodiment, the following briefly introduces the relevant terms involved in this article.

[0077] Subcarrier Space (SCS), in LTE, the bandwidth of a subcarrier spacing in the frequency domain is 15KHz. In NR, the frequency domain bandwidth of the subcarrier spacing can be 15Khz, 30KHz, 60KHz, etc.

[0078] Frequency domain resource RB (Resource Block, RB), which consists of 12 subcarriers in the frequency domain and has a bandwidth of 180KHz. It is the basic unit of LTE and NR frequency domain resource scheduling.

[0079] Rate-matching (RM) is a resource mapping mode defined by the 3GPP protocol, which is mainly used for mutual avoidance between channels.

[0080] Combine the following Figure 1 The information processing method in the embodiment of the present application is described in the communication system framework:

[0081] In an embodiment of the present application, in a spectrum sharing environment, LTE and NR can be applied separately in two base stations or in one base station. The following description takes the application of LTE and NR in one base station as an example.

[0082] For the convenience of description, in the embodiment of the present application, NR wireless access technology is used to represent the first wireless access technology, and LTE wireless access technology is used to represent the second wireless access technology.

[0083] See also Figure 2 In the embodiments of the present application, an information processing method includes:

[0084] 201. The base station obtains a target message;

[0085] The base station obtains one or more target messages.

[0086] From the acquisition path, the target message can be sent to the base station by other base stations through the core network. For example, a software application server needs to send a system message to the terminal, and the message is transmitted through the core network. When the message needs to be transmitted to the base station, the base station obtains the message from the core network.

[0087] It is understandable that the message can also be obtained from other terminals in the cell, that is, the message sent by the terminal in the cell to the NR base station. For example, the first terminal in the cell needs to send a message to the second terminal in the cell, and the base station will receive the message sent by the first terminal. It is understandable that the target message can also be obtained through other means, such as generated by the base station, which is not limited here.

[0088] From the perspective of the target message type, the target message can include the following types:

[0089] Business information class: This type of message is used to transmit business data information to terminals within the cell.

[0090] Initial configuration class: This type of message is a system message used to configure the connection between the base station and the terminal.

[0091] Broadcast configuration class: This type of message is generated by the base station and is used to send broadcast information to terminals in the cell.

[0092] It is understandable that other types of messages may also be used, which are not specifically limited here.

[0093] 202. When the receiver of the target message does not support rate matching RM, the base station determines the time and frequency resources required to send the target message through the NR wireless access technology;

[0094] After the base station obtains the target message, it determines the receiver of the target message. When the receiver does not support the rate matching RM transmission mode, the base station determines the time and frequency resources required to send the target message through NR.

[0095] When the receiver of the target message supports rate matching, the base station can send the message in a rate matching manner. When the base station sends the target message in a rate matching RM manner, interference signals can be avoided in the corresponding time-frequency resources.

[0096] In this embodiment, the base station determines whether the acquired target message supports the sending of the rate matching RM method, including the following situations:

[0097] When the target message obtained by the base station is a system class message generated by the base station, the base station determines that the target message does not support being sent in a rate matching RM manner. For example, when the type of the target message received by the base station is an initial access class, the base station determines that the target message does not support being sent in a rate matching RM manner. It can be understood that the system class message also includes other types of messages, such as a broadcast configuration class. That is, when the target message received by the base station is a broadcast configuration class message, the base station determines that the target message does not support being sent in a rate matching RM manner.

[0098] When the target message obtained by the base station is of the business information type, the base station determines whether the target message supports RM based on the RM capability message reported by the terminal that receives the target message. That is, when the RM capability message reported by the terminal indicates that the terminal supports RM capability, the base station determines that the target message supports being sent in RM mode; when the RM capability message reported by the terminal indicates that the terminal does not support RM capability, the base station determines that the target message does not support being sent in RM mode.

[0099] It should be noted that when the base station does not receive the RM capability message reported by the terminal, it is determined that the target message does not support being sent in RM mode. For example, before the base station and the terminal in the cell complete the RRC configuration, the base station will not receive the RM capability message reported by the terminal, then the message sent by the base station to the terminal is determined to not support being sent in RM mode.

[0100] In this embodiment, the manner in which the base station determines the time-frequency resources required to send the target message through the NR includes the following:

[0101] When the base station obtains the channel quality information of the bandwidth for sending the target message, the base station determines the time-frequency resources required to send the target message through NR based on the message length of the target message and the channel quality information of the bandwidth. The channel quality information is used to indicate the channel quality of the bandwidth. When the measured value of the channel quality is higher than a certain threshold, it indicates that the channel quality is good, and the less information is added to the target message through redundant coding, that is, the less time-frequency resources are required to send the target message through NR. When the channel quality is lower than a certain threshold, it indicates that the channel quality is poor, and the more information is added to the target message through redundant coding, that is, the more time-frequency resources are required to send the target message through NR.

[0102] For example, when the message length of the received target message is 180,000 bits and the measured value of the channel quality obtained is greater than 90, the amount of redundantly coded information is 180,000 bits, and the time-frequency resources for sending the target message are 2RB. When the measured value of the channel quality is less than 70, the amount of redundantly coded information is 360,000 bits, and the time-frequency resources for sending the target message are 3RB.

[0103] When the base station fails to obtain the channel quality information of the bandwidth for sending the target message, the base station determines the time-frequency resources required to send the target message through NR in a manner that the channel quality is lower than a certain threshold.

[0104] It should be noted that the threshold of the channel quality can be set according to actual needs, which is not limited here. It can also be understood that the corresponding redundant coding method can also be different, which is not specifically limited here.

[0105] 203. Eliminate the interference signal to be sent on the bandwidth corresponding to the time-frequency resource;

[0106] After the base station obtains the time-frequency resources, it eliminates the interference signal to be sent on the bandwidth corresponding to the time-frequency resources;

[0107] The base station eliminates the interference signal to be sent on the bandwidth corresponding to the time-frequency resource in the following ways:

[0108] The base station eliminates the interference signal to be sent on the bandwidth corresponding to the time-frequency resource in a silent manner, that is, the base station reduces the transmission power of the interference signal corresponding to the time-frequency resource to 0.

[0109] The base station eliminates the interference signal to be sent on the bandwidth corresponding to the time-frequency resource by sending a cancellation signal, that is, the base station generates a cancellation signal, the parameters of the cancellation signal are set to correspond to the interference signal, and the cancellation signal is sent in the time-frequency resource corresponding to the interference signal.

[0110] The base station can eliminate the interference signal corresponding to the time-frequency resource in different frequency bands of the bandwidth, that is, the base station can eliminate the interference signal corresponding to the time-frequency resource at the lowest frequency position of the bandwidth, and can also eliminate the interference signal corresponding to the time-frequency resource at the highest frequency position of the bandwidth. It can be understood that the interference signal corresponding to the time-frequency resource can also be eliminated in the middle frequency band of the bandwidth, which is not limited here.

[0111] For example, when the bandwidth is 10M, the amount of data transmitted in the bandwidth 1ms is 52RB, and the time-frequency resource is 20RB. The base station can eliminate the interference signal corresponding to 0-20RB in the bandwidth, and can also eliminate the interference signal corresponding to 20-40RB in the bandwidth.

[0112] In this embodiment, the interference signals may include the following:

[0113] Cell-specific reference signal CRS.

[0114] The signal sent in the physical downlink control channel PDCCH channel.

[0115] It can be understood that the signal sent in the physical hybrid automatic repeat indicator channel PHICH channel can also be other types of interference signals, such as the signal sent in the physical control format indicator channel PCFICH channel, which is not specifically limited here.

[0116] 204. The base station sends a target message to the terminal.

[0117] After eliminating the interference signal on the bandwidth corresponding to the time-frequency resource, the base station sends the target message to the terminal through the bandwidth corresponding to the time-frequency resource.

[0118] In the embodiment of the present application, step 202 is an optional step, that is, regardless of whether the target message supports rate matching, the target message can be sent in a frequency band bandwidth that eliminates interference signals.

[0119] This solution eliminates the interference signal of the bandwidth corresponding to the time-frequency resources required by the base station to send the target message through the base station, and sends the target message through the bandwidth corresponding to the time-frequency resources, so as not to cause interference, thereby improving the transmission quality of the NR message sent by the base station to the terminal.

[0120] The above describes the application of NR and LTE to one base station. The following describes the application of NR and LTE to two base stations. Figure 3 , another method of the embodiment of the present application includes:

[0121] 301. The NR base station obtains a target message;

[0122] The NR base station obtains one or more target messages.

[0123] From the acquisition path, the target message can be sent to the base station by other base stations through the core network. For example, a software application server needs to send a system message to the terminal, and the message is transmitted through the core network. When the message needs to be transmitted to the base station, the base station obtains the message from the core network.

[0124] It is understandable that the message can also be obtained from other terminals in the cell, that is, the message sent by the terminal in the cell to the NR base station. For example, the first terminal in the cell needs to send a message to the second terminal in the cell, and the NR base station will receive the message sent by the first terminal. It is understandable that the target message can also be obtained through other means, such as generated by the NR base station, which is not limited here.

[0125] From the perspective of the target message type, the target message can include the following types:

[0126] Business information class: This type of message is used to transmit business data information to terminals within the cell.

[0127] Initial configuration class: This type of message is a system message used to configure the connection between the base station and the terminal.

[0128] Broadcast configuration class: This type of message is generated by the base station and is used to send broadcast information to terminals in the cell.

[0129] It is understandable that other types of messages may also be used, which are not specifically limited here.

[0130] 302. When the receiver of the target message does not support rate matching RM, the NR base station determines the time and frequency resources required to send the target message through the NR radio access technology;

[0131] After the NR base station obtains the target message, it determines the recipient of the target message. When the recipient does not support the rate matching RM sending method, the NR base station determines the time and frequency resources required to send the target message through NR.

[0132] When the receiver of the target message supports rate matching, the NR base station can send the message by rate matching. When the NR base station sends the target message by rate matching RM, it can avoid interference signals in the corresponding time-frequency resources.

[0133] In this embodiment, the NR base station determines whether the acquired target message supports the rate matching RM method to send the following situations:

[0134] When the target message obtained by the NR base station is a system class message generated by the NR base station, the NR base station determines that the target message does not support being sent in a rate matching RM manner. For example, when the target message received by the NR base station is an initial access class, the NR base station determines that the target message does not support being sent in a rate matching RM manner. It can be understood that the system class message also includes other messages, such as a broadcast configuration class. That is, when the target message received by the NR base station is a broadcast configuration class, the NR base station determines that the target message does not support being sent in a rate matching RM manner.

[0135] When the target message obtained by the NR base station is of the service information type, the NR base station determines whether the target message supports being sent in RM mode based on the RM capability message reported by the terminal that receives the target message. That is, when the RM capability message reported by the terminal indicates that the terminal supports RM capability, the NR base station determines that the target message supports being sent in RM mode; when the RM capability message reported by the terminal indicates that the terminal does not support RM capability, the NR base station determines that the target message does not support being sent in RM mode.

[0136] It should be noted that when the NR base station does not receive the RM capability message reported by the terminal, it is determined that the target message does not support being sent in RM mode. For example, before the NR base station and the terminal in the cell complete the RRC configuration, the NR base station will not receive the RM capability message reported by the terminal. Then, the messages sent by the base station to the terminal are determined to not support being sent in RM mode.

[0137] In this embodiment, the NR base station determines the time-frequency resources required to send the target message through NR in the following ways:

[0138] When the NR base station obtains the channel quality information of the bandwidth for sending the target message, the NR base station determines the time-frequency resources required to send the target message through NR based on the message length of the target message and the channel quality information of the bandwidth. The channel quality information is used to indicate the channel quality of the bandwidth. When the measured value of the channel quality is higher than a certain threshold, it means that the better the channel quality is, the less information is added to the target message through redundant coding, that is, the less time-frequency resources are required to send the target message through NR. When the channel quality is lower than a certain threshold, it means that the worse the channel quality is, the more information is added to the target message through redundant coding, that is, the more time-frequency resources are required to send the target message through NR.

[0139] For example, when the message length of the received target message is 180,000 bits and the measured value of the channel quality obtained is greater than 90, the amount of redundantly coded information is 180,000 bits, and the time-frequency resources for sending the target message are 2RB. When the measured value of the channel quality is less than 70, the amount of redundantly coded information is 360,000 bits, and the time-frequency resources for sending the target message are 3RB.

[0140] When the NR base station fails to obtain the channel quality information of the bandwidth for sending the target message, the NR base station determines the time and frequency resources required to send the target message through NR in a manner that the channel quality is lower than a certain threshold.

[0141] It should be noted that the threshold of the channel quality can be set according to actual needs, which is not limited here. It can also be understood that the corresponding redundant coding method can also be different, which is not specifically limited here.

[0142] 303. The NR base station sends a notification message to the LTE base station;

[0143] When the NR base station determines the time-frequency resources required to send the target message through the NR wireless access technology, the NR base station sends a notification message to the LTE base station. The notification message is used to indicate the time-frequency resources required to send the target message through the NR wireless access technology, that is, the notification message includes but is not limited to the following information: the frequency domain resources RB required to send the target message through the NR wireless access, the subframe for sending the target message, and other information.

[0144] 304. Acquire a first time-frequency domain resource required to send a target message through NR wireless access technology;

[0145] When the LTE base station receives the notification message, it reads the notification message and then obtains the time and frequency resources required to send the target message through NR wireless access technology.

[0146] 305. Eliminate the interference signal to be sent on the bandwidth corresponding to the time-frequency resource;

[0147] After the LTE base station obtains the time-frequency resources, it eliminates the interference signal to be sent on the bandwidth corresponding to the time-frequency resources;

[0148] The LTE base station eliminates the interference signal to be sent on the bandwidth corresponding to the time-frequency resource in the following ways:

[0149] LTE eliminates the interference signal to be sent on the bandwidth corresponding to the time-frequency resource by silent means. For example, the LTE base station reduces the transmission power of the interference signal corresponding to the time-frequency resource to 0.

[0150] LTE eliminates the interference signal to be sent on the bandwidth corresponding to the time-frequency resource by sending a cancellation signal, that is, the LTE base station generates a cancellation signal, the parameters of the cancellation signal are set to correspond to the interference signal, and the cancellation signal is sent in the time-frequency resource corresponding to the interference signal.

[0151] The LTE base station can eliminate the interference signal corresponding to the time-frequency resource in different frequency bands of the bandwidth, that is, the LTE base station can eliminate the interference signal corresponding to the time-frequency resource at the lowest frequency position of the bandwidth, and can also eliminate the interference signal corresponding to the time-frequency resource at the highest frequency position of the bandwidth. It can be understood that the interference signal corresponding to the time-frequency resource can also be eliminated in the middle frequency band of the bandwidth, which is not limited here.

[0152] For example, when the bandwidth is 10M, the amount of data transmitted in the bandwidth 1ms is 52RB, and the time-frequency resource is 20RB. The base station can eliminate the interference signal corresponding to 0-20RB in the bandwidth, and can also eliminate the interference signal corresponding to 20-40RB in the bandwidth.

[0153] In this embodiment, the interference signals may include the following:

[0154] Cell-specific reference signal CRS.

[0155] The signal sent in the physical downlink control channel PDCCH channel.

[0156] It can be understood that the signal sent in the physical hybrid automatic repeat indicator channel PHICH channel can also be other types of interference signals, such as the signal sent in the physical control format indicator channel PCFICH channel, which is not specifically limited here.

[0157] 306. The LTE base station sends notification information to the NR base station;

[0158] After the LTE base station eliminates the interference signal of the bandwidth corresponding to the time-frequency resources, the LTE base station sends a notification message to the NR base station, where the notification message is used to indicate that the LTE base station eliminates the interference signal of the bandwidth corresponding to the time-frequency resources.

[0159] 307. The NR base station sends the target message to the terminal.

[0160] After the NR base station receives the notification message, the NR base station reads the notification message, obtains the information that the LTE base station has eliminated the interference signal on the bandwidth corresponding to the time-frequency resources, and then sends the target message to the terminal through the bandwidth corresponding to the time-frequency resources.

[0161] In actual application, if the target message supports being sent in RM mode, the target message can also be sent in a frequency band bandwidth that eliminates interference signals. This embodiment of the present application does not limit this.

[0162] In this embodiment, the interference signal of the bandwidth corresponding to the time-frequency resources required for sending the target message is eliminated through the LTE base station, and the target message is sent through the NR base station on the bandwidth corresponding to the time-frequency resources, so that the target message can be sent without interference every millisecond. Compared with sending interference-free NR messages through MBSFN, which requires waiting for a fixed subframe to be sent, it saves time and improves efficiency.
