Background Art

[0002] Generally, in the process of communication transmission between a terminal device and a network device, if the frequencies between the uplink signal transmitted by the terminal device and the downlink signal received by the terminal device are too close, harmonic or intermodulation interference may occur to the received downlink signal.

[0057] To facilitate understanding, we will first explain the terminology used in this disclosure. 1. Harmonic interference and intermodulation interference Intermodulation interference is caused by nonlinear circuits within the transmission channel. Harmonics are radio waves that are integer multiples of the fundamental frequency generated during the modulation process of radio waves. When these harmonic frequencies overlap with the receiving frequency, they interfere with the receiver, and this interference is called harmonic interference. When two or more signals of different frequencies are input to a nonlinear circuit, multiple harmonics and combined frequency components are generated due to the action of the nonlinear device. Here, a combined frequency component close to the required received signal frequency ω0 can pass smoothly through the receiver and generate interference, and such interference is called intermodulation interference. 2. Receiver sensitivity Receiver sensitivity defines the minimum signal strength at which a receiver can receive and operate properly. Sensitivity may be a single power level and is usually expressed in decibels relative to one milliwatt (dBM). 3. Receiver sensitivity fallback It is permissible for a terminal to reduce or fall back its receiver sensitivity in certain frequency bands due to internal harmonics and intermodulation interference. The performance metric that allows for terminal receiver sensitivity fallback is the maximum sensitivity degradation (MSD), identified in decibel relative (dB).

[0058] To better understand the interference control methods disclosed in the embodiments of this disclosure, the following describes a communication system to which the embodiments of this disclosure can be applied.

[0059] Referring to Figure 1, Figure 1 is an architectural diagram of a communication system provided by an embodiment of the present disclosure. The communication system includes, but is not limited to, one network device and one terminal device. The number and form of devices shown in Figure 1 are illustrative and do not limit the embodiments of the present disclosure. Actual applications may include two or more network devices and two or more terminal devices. The communication system shown in Figure 1, for example, includes one network device 11 and one terminal device 12.

[0060] Furthermore, the technical concepts of the embodiments described herein are applicable to a variety of communication systems, such as long-term evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems.

[0061] In the embodiments of this disclosure, the network device 11 is a network-side entity for sending and receiving signals. For example, the network device 11 is 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. The embodiments of this disclosure do not limit the specific technology or specific device form used for the network device. The network device provided by the embodiments of this disclosure can consist of a central unit (CU) and a distributed unit (DU), where the CU may also be called a control unit. By using a CU-DU structure, network devices such as the protocol layer of a base station can be isolated, with some protocol layer functions centrally controlled in the CU, and the remaining or all of the protocol layer functions distributed in the DU, which is centrally controlled by the CU.

[0062] In the embodiments of this disclosure, the terminal device 12 is a user-side entity for sending and receiving signals, such as a mobile phone. The terminal device may also be called a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be an automobile with communication functions, a smart car, a mobile phone, a wearable device, a pad, a computer with wireless transmission and reception functions, 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 specific device form used for the terminal device.

[0063] The communication systems described in the embodiments of this disclosure are intended to provide a clearer explanation of the technical solutions of the embodiments and do not limit the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will see, as system architectures evolve and new business scenarios emerge, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical challenges.

[0064] The interference control method and apparatus provided in this disclosure will be described in detail below, with reference to the drawings.

[0065] Referring to Figure 2, Figure 2 is a schematic flowchart of an interference control method provided by an embodiment of the present disclosure, which is performed by a terminal device. As shown in Figure 2, the method may include, but is not limited to, the following step 21.

[0066] Step 21: Send first instruction information to indicate interference information of the terminal device.

[0067] In a typical communication system, if the frequencies of the uplink data transmitted by a terminal device and the downlink data received by the terminal device are too close, harmonic or intermodulation interference may occur in the received downlink data. This can prevent the terminal device from receiving the downlink data properly and further affect communication transmission.

[0068] In embodiments of this disclosure, a terminal device may transmit first instruction information to a network device so that the network device becomes aware of interference information about the terminal device. By adjusting time-frequency domain resources corresponding to the interference information, reliable reception of downlink data is ensured, communication transmission is guaranteed, and the quality and efficiency of communication transmission are improved.

[0069] The interference information from the terminal device may also be uplink transmission frequency information, depending on the option.

[0070] For example, the first instruction information sent by the terminal device to the network device indicates that the interfered uplink transmission frequency is F1. Therefore, when the network device sends downlink data to the terminal device, it may adjust the resources used to transmit the downlink data accordingly. For example, it may stagger the transmission time of the downlink data with the transmission time of the uplink transmission frequency F1, or it may use another frequency that is farther from F1 to transmit the downlink data.

[0071] The uplink transmission frequency information may optionally 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., but this disclosure is not limited thereto.

[0072] Selectively, the harmonic signal information for the uplink transmission frequency may include at least one of the following: multiples of the harmonic signals relative to the fundamental signal, or the frequency range of the harmonic signals, or multiples of the harmonic signals relative to the fundamental signal and the frequency range of the harmonic signals.

[0073] For example, the number of harmonic signals with respect to the fundamental signal of uplink transmission frequency F1 is 2, the frequency range of the harmonic signals is 20 megahertz (MHz) to 50 MHz, and the uplink transmission frequency information may be the uplink transmission frequency F1, or the number of harmonic signals with respect to the fundamental signal of uplink transmission frequency F1 is 2, or the number of harmonic signals with respect to the fundamental signals of uplink transmission frequencies F1 and F1 is 2, and the frequency range of the harmonic signals is 20 MHz to 50 MHz, and this disclosure is not limited thereto.

[0074] The interference information from the terminal device may be a combination of uplink transmission frequency information, as selectable.

[0075] For example, the first instruction information transmitted by the terminal device to the network device indicates that the interfered uplink transmission frequency combination is combination 1, and since combination 1 corresponds to uplink transmission frequencies F1 and F2, the network device can know that the uplink transmission frequencies being interfered with by the terminal device are F1 and F2. Subsequently, the network device determines, based on the time-domain resources corresponding to F1 and F2 respectively, whether or not F1 and F2 will interfere with the downlink frequency F3 after intermodulation, thereby staggering the usage times of F1 and F2. The network device may also adjust the resources that transmit downlink data for the interfered frequency F3 accordingly, for example, by staggering the transmission time of the downlink data and the transmission time of the uplink transmission frequency F1, or by staggering the transmission time of the downlink data and the transmission time of the uplink transmission frequency F2.

[0076] The interference information for the terminal device may be a combination of uplink transmission frequency information and downlink reception frequency information, as selectable.

[0077] For example, the first instruction information that a terminal device sends to a network device indicates that the interfered uplink transmission frequency is F1 and the interfered downlink frequency is F2, so that the network device can understand that the uplink transmission frequency that is being interfered with by the terminal device is F1 and the interfered downlink frequency 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, and if F1 and F2 are interfering with each other, it may stagger the usage times of F1 and F2. If the interfering uplink transmission frequency F1 and the interfered downlink frequency F2 are caused by other factors, the network device may, when sending downlink data to the terminal device, adjust the resources used to transmit the downlink data accordingly, for example, by staggering the transmission time of the downlink data and the transmission time of the uplink transmission frequency F1, or by transmitting the downlink data using another frequency that is farther from F2.

[0078] The interference information from the terminal device may also be downlink reception frequency information, depending on the option.

[0079] For example, the first instruction information transmitted by the terminal device to the network device indicates that the interfered downlink frequency information is F1, and the network device may, in turn, adjust the resources used to transmit downlink data to the terminal device, for example, by using another frequency that is farther away from F1 to transmit the downlink data.

[0080] The interference information of the terminal device may be a correspondence between uplink transmission frequency information and downlink reception frequency information, as selectable.

[0081] For example, the first instruction information transmitted by the terminal device to the network device specifies the uplink transmission frequency F1 and the interference downlink reception frequency F2. As a result, when the network device transmits downlink data to the terminal device, it may adjust the resources used to transmit the downlink data accordingly. For example, it may stagger the transmission time of the uplink transmission frequency F1 and the transmission time of the downlink reception frequency F2.

[0082] The interference information of the terminal device may be, as selectable, a correspondence between uplink transmission frequency information combinations and downlink reception frequency information.

[0083] For example, the first instruction information transmitted by the terminal device to the network device specifies its uplink transmission frequencies F1 and F2, and the intermodulation downlink reception frequency F3. As a result, when the network device transmits downlink data to the terminal device, it may adjust the resources used to transmit the downlink data accordingly. For example, it may stagger the transmission time of the downlink reception frequency F3 and the transmission times of the uplink transmission frequencies F1 and F2, or it may stagger the transmission times of the uplink transmission frequencies F1 and F2.

[0084] Interference information from the terminal device may be receiver sensitivity information, depending on the option.

[0085] For example, the first instruction information sent by the terminal device to the network device indicates that the information to be interfered with is receiver sensitivity information, and the network device may adjust the resources used to transmit downlink data or the uplink transmission power based on the receiver sensitivity information to avoid interference as much as possible when transmitting downlink data to the terminal device.

[0086] The interference information for the terminal device may be either an interfering wireless technology instruction or an interfered wireless technology instruction.

[0087] Here, the interfering radio technology specification may be LTE radio technology, 5G NR radio technology, or the 3rd generation partnership project (3GPP®) radio technology. Correspondingly, the interfered radio technology specification may be LTE radio technology, 5G NR radio technology, or the 3rd generation partnership project (3GPP) radio technology.

[0088] For example, a protocol specification can characterize the interfering radio technology specification and the interfered radio technology specification by the possible values ​​of a particular bit.

[0089] For example, in the protocol specification: the possible values ​​of the first three bits in the first instruction information characterize the interfering radio technology instruction, and the possible values ​​of the fourth to sixth bits in the first instruction information characterize the interfered radio technology. Here, when the possible value of the first bit is 1, the interfering radio technology is characterized as LTE radio technology; when the possible value of the second bit is 1, the interfering radio technology is characterized as 5G NR radio technology; when the possible value of the third bit is 1, the interfering radio technology is characterized as 3GPP radio technology; when the possible value of the fourth bit is 1, the interfered radio technology is characterized as LTE radio technology; when the possible value of the fifth bit is 1, the interfered radio technology is characterized as 5G NR radio technology; and when the possible value of the sixth bit is 1, the interfered radio technology is characterized as 3GPP radio technology. As a result, network devices can determine the interfering radio technology instruction and the interfered radio technology instruction, etc., based on the possible values ​​of specific bits, and this disclosure is not limited to this.

[0090] The first instruction information transmitted by the terminal device to the network device may indicate one or more of the above-mentioned interference information, and this disclosure is not limited thereto.

[0091] The above examples are merely illustrative and should not be considered as limitations on interference information, etc., of terminal devices in the embodiments of this disclosure.

[0092] By implementing the embodiments of this disclosure, a terminal device may transmit first instruction information to a network device so that the network device becomes aware of interference information of the terminal device, and by adjusting the time-frequency domain resources corresponding to the interference information, reliable reception of downlink data is ensured, communication transmission is guaranteed, and ultimately the quality and efficiency of communication transmission are improved.

[0093] Referring to Figure 3, Figure 3 is a schematic flowchart of an interference control method provided by an embodiment of the present disclosure, which is performed by a terminal device. As shown in Figure 3, the method may include, but is not limited to, the following step 31.

[0094] Step 31: In response to the specified transmission conditions being met, first instruction information is transmitted to indicate interference information for the terminal device.

[0095] Optionally, the terminal device may determine the specified transmission conditions according to the protocol specifications.

[0096] For example, the protocol specification or specified transmission condition may be that the receiver sensitivity is below a first threshold.

[0097] Here, the first threshold may be set by a network device or based on a protocol specification, but this disclosure is not limited thereto.

[0098] For example, based on a protocol specification, it is determined that a specified transmission condition is that the receiver sensitivity is below a first threshold. For example, the first threshold is -80 dBM, and the receiver sensitivity of a terminal device is -96 dBM. If, after interference, the terminal device's receiver sensitivity becomes -70 dBM, and its sensitivity is less than the first threshold sensitivity of -80 dBM, i.e., the specified transmission condition is met, the terminal device may transmit first instruction information to a network device to instruct it about the interference, etc., and this disclosure is not limited thereto.

[0099] Selectively, the specified transmission condition may be that the receiver sensitivity reduction value is greater than or equal to the second threshold.

[0100] The second threshold may be set by a network device or based on a protocol specification, but this disclosure is not limited thereto.

[0101] For example, the protocol specification determines that a specified transmission condition is that the receiver sensitivity reduction value is greater than or equal to a second threshold. For example, the second threshold is 20 dBM, and the receiver sensitivity of a terminal device is -96 dBM. After the terminal device is subjected to interference, if its receiver sensitivity changes to -70 dBM, the receiver sensitivity reduction value of the terminal device is 26 dBM, which is greater than the second threshold of 20 dBM, i.e., the specified transmission condition is met. As a result, the terminal device may transmit first instruction information to a network device to instruct it to provide information about the interference of the terminal device, etc., and this disclosure is not limited thereto.

[0104] The third threshold may be a number specified by the protocol or a number set by the network device, and this disclosure is not limited to such a number.

[0105] For example, if the third threshold is 20 dB, the first measurement result is the signal-to-interference-to-noise ratio and the value is 20 dB, and both are equal, the specified transmission conditions are met, and therefore the terminal device can transmit first instruction information to the network device to instruct it on interference information, etc., and this disclosure is not limited thereto.

[0106] Optionally, the specified transmission condition may be that the second measurement result is equal to or greater than the fourth threshold.

[0107] The fourth threshold may be a numerical value specified by the protocol or a numerical value set by the network device, and this disclosure is not limited thereto.

[0108] Optionally, the second measurement result may be the block error ratio (BLER).

[0109] For example, if the fourth threshold is 10%, and the second measurement result is the block error rate and the value is 15%, which is greater than the fourth threshold and satisfies the specified transmission conditions, then the terminal device can transmit the first instruction information to the network device to instruct it about interference information, etc., and this disclosure is not limited thereto.

[0128] Furthermore, for example, uplink transmission frequency information combination 1 is frequencies A and B, and the order of the intermodulation signal is first order, and therefore the intermodulation signals may be A and B.

[0129] Alternatively, uplink transmission frequency information combination 1 may be frequencies A and B, the order of the intermodulation signal is second order, and the operation relationship between each frequency in the intermodulation signal is "+" and "-", and therefore the intermodulation signals may be (A+B) and (AB).

[0250] For specific details and implementation methods of the interference information of terminal devices, please refer to the descriptions of other embodiments in this disclosure; a detailed explanation is omitted here.

[0251] For specific details and implementations of Step 91, please refer to the descriptions of other embodiments of this disclosure, and a detailed explanation is omitted here.

[0252] Step 92: Based on the first instruction information, update the frequency information and / or uplink carrier aggregation information corresponding to the terminal device.

[0253] Optionally, the network device may stagger the transmission time of the uplink transmission frequency and the reception time of the downlink reception frequency as indicated by the first instruction information.

[0254] For example, if the transmission time of the uplink transmission frequency indicated by the first instruction information is t1, the reception time of the downlink reception frequency can be determined to be any one time different from t1, such as t2, t3, etc., and this disclosure is not limited thereto.

[0255] Optionally, the network device may disable one or more uplink transmit frequencies in the uplink transmit frequency information combination or the uplink transmit frequency information indicated by the first instruction information.

[0256] For example, if the uplink transmission frequency indicated by the first instruction information is F1, the network device may instruct the terminal device to perform uplink transmission using a different frequency resource than F1, thereby disabling the uplink transmission frequency F1, but this disclosure does not limit it.

[0257] Alternatively, if the uplink transmission frequencies in the uplink transmission frequency information combination indicated by the first instruction information are F1, F2, and F3, the network device may disable uplink transmission frequency F1 by instructing the terminal device to perform uplink transmission using a different frequency resource than F1, or the network device may disable uplink transmission frequencies F1 and F2 by instructing the terminal device to perform uplink transmission using a different frequency resource than F1 and F2, and this disclosure is not limited thereto.

[0258] The transmission times of all or some of the uplink frequencies in the uplink transmission frequency information combination indicated by the first instruction information may be shifted as selectable.

[0259] For example, in the uplink transmission frequency information combination indicated by the first instruction information, the uplink frequencies are F1 and F2. The network device can avoid the occurrence of corresponding intermodulation interference by shifting the transmission time of uplink frequency F1 and the transmission time of uplink frequency F2.

[0260] Alternatively, the uplink frequencies in the uplink transmission frequency combination indicated by the first instruction information are F1, F2, and F3, and the network device may stagger the transmission times of F1, F2, and F3, or stagger the transmission time of F1 with the transmission times of F2 and F3, or stagger the transmission time of F2 with the transmission times of F1 and F3, or stagger the transmission time of F3 with the transmission times of F1 and F2, and this disclosure is not limited thereto.

[0261] Optionally, the network device may disable the downlink receiving frequency indicated by the first instruction information.

[0262] For example, if the first instruction indicates that the downlink receiving frequency of interference is F1, the network device may override the downlink receiving frequency F1 indicated by the first instruction, and may, for example, transmit downlink data using another frequency that is farther from F1, rather than F1-transmitted downlink received data, and this disclosure is not limited thereto.

[0263] Optionally, the network device may instruct the terminal device to reduce the uplink transmit power.

[0264] Furthermore, the higher the uplink transmission power, the greater the interference to the downlink reception. Therefore, by instructing terminal devices to reduce their uplink transmission power, interference to terminal devices can be reduced.

[0265] The network device may adjust time-frequency domain resources corresponding to interference information using any one of the above methods, or it may adjust time-frequency domain resources corresponding to interference information using a combination of the above methods, and this disclosure is not limited thereto.

[0266] The above examples are merely illustrative and do not limit the methods by which a network device updates frequency information and / or uplink carrier aggregation information corresponding to a terminal device in the embodiments of this disclosure.

[0267] By implementing the embodiments of this disclosure, the network device may first acquire interference information of a terminal device based on the received first instruction information, and then update frequency information and / or uplink carrier aggregation information corresponding to the terminal device based on the first instruction information, thereby ensuring reliable reception of downlink data, guaranteeing communication transmission, and ultimately improving the quality and efficiency of communication transmission.
