[0175] To facilitate understanding, the terminology used in this disclosure will be introduced first.

[0176] 1. Harmonic interference and intermodulation interference

[0177] Intermodulation interference is generated by nonlinear circuits in the transmission channel. Harmonics are radio waves that are integer multiples of the fundamental frequency, generated during the modulation process of radio waves. When the frequency of a harmonic coincides with the receiving frequency, it will interfere with the receiver; this interference is called harmonic interference.

[0178] When two or more signals of different frequencies are input to a nonlinear circuit, multiple harmonics and combined frequency components may be generated due to the action of the nonlinear device. Among them, the combined frequency components that are close to the required received signal frequency ω0 can pass through the receiver smoothly and form interference. This kind of interference is called intermodulation interference.

[0179] 2. Receiver sensitivity

[0180] Receiver sensitivity defines the minimum signal strength a receiver can receive without requiring it to function properly. Sensitivity can be a power level, typically expressed in decibels relative to one milliwatt (dBM).

[0181] 3. Receiver sensitivity regression

[0182] Due to internal harmonics and intermodulation interference, the terminal is allowed to reduce or back down its receiver sensitivity for specific frequency bands. The performance metric that allows for receiver sensitivity back-down is the maximum sensitivity degradation (MSD), expressed in decibels (dB).

[0183] To better understand the interference control method disclosed in this embodiment, the communication system to which this embodiment applies is first described below.

[0184] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, two or more network devices and two or more terminal devices may be included. Figure 1 The communication system shown is an example including a network device 11 and a terminal device 12.

[0186] The network device 11 in this disclosure is a network-side entity used for transmitting or receiving signals. For example, the network device 11 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or device form used in the network device. The network device provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0187] The terminal device 12 in this disclosure is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of this disclosure do not limit the specific technology or device form used in the terminal device.

[0188] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0189] The interference control method and apparatus provided in this disclosure will be described in detail below with reference to the accompanying drawings.

[0190] Please see Figure 2 , Figure 2 This is a flowchart illustrating an interference control method provided in an embodiment of this disclosure, which is executed by a terminal device. Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0191] Step 21: Send first indication information, wherein the first indication information is used to indicate interference information of the terminal device.

[0192] In a communication system, if the frequency of the uplink data sent by a terminal device is too close to that of the downlink data it receives, it may cause harmonic or intermodulation interference to the downlink data it receives. This may result in the terminal device being unable to receive the downlink data normally, thus affecting the communication transmission.

[0193] In this embodiment of the present disclosure, the terminal device can send a first indication message to the network device so that the network device can know the interference information of the terminal device, and then adjust the time and frequency domain resources corresponding to the interference information, thereby ensuring the reliable reception of downlink data, providing a guarantee for communication transmission, and thus improving the quality and efficiency of communication transmission.

[0194] Optionally, the interference information for the terminal device can be uplink transmission frequency information.

[0195] For example, the terminal device sends a first indication message to the network device, indicating that the uplink transmission frequency causing interference is F1. This allows the network device to adjust the resources for transmitting downlink data when sending downlink data to the terminal device. For example, the transmission time of downlink data can be staggered from the transmission time of uplink transmission frequency F1, or other frequencies that are far away from F1 can be used to transmit downlink data.

[0196] Optionally, the uplink transmission frequency information may include the uplink transmission frequency, or it may include harmonic signal information of the uplink transmission frequency, or it may include the uplink transmission frequency and its harmonic signal information, etc., and this disclosure does not limit it.

[0197] Optionally, the harmonic signal information of the uplink transmission frequency may include the multiple of the harmonic signal relative to the fundamental signal; or it may include the frequency range of the harmonic signal, or it may include both the multiple of the harmonic signal relative to the fundamental signal and the frequency range of the harmonic signal.

[0198] For example, if the harmonic signal of the uplink transmission frequency F1 is 2 times the fundamental signal, and the frequency range of the harmonic signal is 20 MHz to 50 MHz, then the uplink transmission frequency information can be: uplink transmission frequency F1; or it can be: the harmonic signal of the uplink transmission frequency F1 is 2 times the fundamental signal; or it can be: uplink transmission frequency F1, the harmonic signal of F1 is 2 times the fundamental signal, and the frequency range of the harmonic signal is 20 MHz to 50 MHz, etc. This disclosure does not limit this.

[0199] Optionally, the interference information of the terminal device can be a combination of uplink transmission frequency information.

[0200] For example, the terminal device sends a first indication to the network device, indicating that the uplink transmission frequency combination causing interference is combination 1. This combination 1 corresponds to uplink transmission frequencies F1 and F2, thus enabling the network device to know that the uplink transmission frequencies causing interference from the terminal device are F1 and F2. The network device can then determine, based on the time-domain resources corresponding to F1 and F2 respectively, whether F1 and F2 are intermodulating the downlink frequency F3, and thus stagger the usage times of F1 and F2. The network device can also adjust the resources for transmitting downlink data at the interfered frequency F3 accordingly, for example, by staggering the downlink data transmission time from the transmission time of uplink transmission frequency F1, or by staggering the downlink data transmission time from the transmission time of uplink transmission frequency F2.

[0201] Optionally, the interference information of the terminal device can be a combination of uplink transmission frequency information and downlink reception frequency information.

[0202] For example, the terminal device sends a first indication to the network device, indicating that the uplink transmission frequency causing the interference is F1 and the downlink frequency being interfered with is F2. This allows the network device to know that the terminal device is causing the interference with the uplink transmission frequency F1 and the downlink frequency being interfered with is F2. The network device can then determine whether F1 and F2 are interfering with each other based on the time-domain resources corresponding to F1 and F2, respectively. If they are interfering, the usage times of F1 and F2 can be staggered. If the uplink transmission frequency F1 causing the interference and the downlink frequency F2 being interfered with are due to other reasons, the network device can adjust the resources for sending downlink data when sending it to the terminal device. For example, the downlink data transmission time can be staggered from the transmission time of the uplink transmission frequency F1, or other frequencies farther away from F2 can be used for downlink data transmission.

[0203] Optionally, the interference information of the terminal device can be downlink receiving frequency information.

[0204] For example, the terminal device sends a first indication message to the network device, indicating that the downlink frequency information it is interfering with is F1. This allows the network device to adjust the resources for sending downlink data when sending downlink data to the terminal device. For example, it can use other frequencies that are far away from F1 to send downlink data.

[0205] Optionally, the interference information of the terminal device can be the correspondence between uplink transmission frequency information and downlink reception frequency information.

[0206] For example, the terminal device sends a first indication message to the network device, instructing its uplink transmission frequency F1 to interfere with the downlink reception frequency F2. This allows the network device to adjust the resources for transmitting downlink data when sending downlink data to the terminal device. For example, the transmission time of the uplink transmission frequency F1 can be staggered with the transmission time of the downlink reception frequency F2.

[0207] Optionally, the interference information of the terminal device can be the correspondence between the uplink transmission frequency information combination and the downlink reception frequency information.

[0208] For example, the terminal device sends a first indication message to the network device, instructing its uplink transmission frequencies F1 and F2 to intermodulate the downlink receiving frequency F3. This allows the network device to adjust the resources for transmitting downlink data when sending downlink data to the terminal device. For example, the transmission time of the downlink receiving frequency F3 can be staggered from the transmission times of the uplink transmission frequencies F1 and F2, or the transmission times of the uplink transmission frequencies F1 and F2 can be staggered.

[0209] Optionally, the interference information of the terminal device can be receiver sensitivity information.

[0210] For example, the terminal device sends a first indication message to the network device, indicating that its interference information is receiver sensitivity information. This allows the network device to adjust the resources for transmitting downlink data or adjust the uplink transmission power based on the receiver sensitivity information when transmitting downlink data to the terminal device, so as to minimize interference.

[0372] By implementing the embodiments of this disclosure, the network device can learn the terminal device's ability to report interference information based on the received third indication information. Then, it can send a second indication information to the terminal device so that the terminal device can learn the specified transmission conditions corresponding to the first indication information.

[0378] Optionally, the network device may stagger the transmission time of the uplink transmission frequency indicated by the first indication information with the reception time of the downlink reception frequency.

[0384] For example, if the uplink transmission frequency information combination indicated by the first indication information is F1 and F2, the network device can stagger the transmission time of uplink frequency F1 with the transmission time of uplink frequency F2 to avoid corresponding intermodulation interference.

[0385] Alternatively, if the uplink transmission frequency combination indicated by the first indication information is F1, F2, and F3, the network device can stagger the transmission times of F1, F2, and F3; or, the transmission time of F1 can be staggered from the transmission times of F2 and F3; or, the transmission time of F2 can be staggered from the transmission times of F1 and F3; or, the transmission time of F3 can be staggered from the transmission times of F1 and F2, etc. This disclosure does not limit this.

[0386] Optionally, the network device may also invalidate the downlink receiving frequency indicated by the first indication information.

[0387] For example, if the first indication information indicates that the downlink receiving frequency of the interference is F1, the network device can invalidate the downlink receiving frequency F1 indicated by the first indication information. For example, it can not use F1 to send downlink receiving data, or use other frequencies that are far away from F1 to send downlink data, etc. This disclosure does not limit this.

[0388] Optionally, the network device may also instruct the terminal device to reduce the uplink transmission power.

[0389] It is understandable that the higher the uplink transmission power, the greater the interference to the downlink reception. Therefore, interference to the terminal equipment can be reduced by instructing the terminal equipment to reduce the uplink transmission power.

[0390] It is understood that network devices can adjust the time-frequency domain resources corresponding to the interference information through one of the above methods, or through multiple of the above methods, etc. This disclosure does not limit this.
