Abstract

Embodiments of the present application relate to the technical field of communications, and provide a communication method and apparatus, for use in reducing the effect of an interference signal on an LP-WUR. In the method, when a terminal device determines that the interference level in a first frequency band satisfies a first condition, the terminal device can monitor a downlink control channel by means of a main path receiver, and an LP-WUR is turned off in the first frequency band. That is, the terminal device maintains normal operation of the main path receiver while keeping the LP-WUR in an off state in the first frequency band. In this way, it can be ensured that the terminal device can operate normally when the interference level in the first frequency band satisfies the first condition, for example, when the terminal device is subjected to relatively large interference in the first frequency band, such that the situation that channel blockage or damage of the LP-WUR causes channel saturation, resulting in the inability to demodulate signals normally is avoided, so as to reduce the effect of an interference signal on the LP-WUR, thereby improving communication stability.

Communication method and device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on April 3, 2024, with application number 202410405661.6 and application name “Communication Method and Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a communication method and device. Background Art

[0003] To save power in terminal devices, the new radio (NR) system specified by the 3rd Generation Partnership Project (3GPP) protocol introduced a low-power wake-up signal (LP-WUS) and a low-power wake-up receiver (LP-WUR) in release (R) 18. The LP-WUR monitors the LP-WUS and, upon receiving it, wakes up or triggers the primary receiver to receive and process downlink control channels. For terminal devices using LP-WUR, the primary receiver is immune to protocol-defined interference signals.

[0004] However, when a terminal device is subject to strong interference signals, the LP-WUR may be damaged and unable to function properly, thus affecting energy conservation and communication stability. Therefore, how to reduce the impact of interference signals on the LP-WUR is an urgent problem to be solved. Summary of the Invention

[0005] The embodiments of the present application provide a communication method and apparatus for reducing the impact of interference signals on LP-WUR.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions:

[0007] On the first aspect, a communication method is provided, which can be executed by a terminal device, or by a module (such as a processor, chip, or chip system, etc.) applied to the terminal device, or by a logical node, logic module or software that can realize all or part of the terminal device functions. For the convenience of expression, the following introduction is made by taking the execution of the method by the terminal device as an example. The method includes: determining that the first detection result meets the first condition, and monitoring the downlink control channel through the main receiver of the terminal device, and the LP-WUR of the terminal device is turned off on the first frequency band. The first detection result indicates the degree of interference on the first frequency band.

[0008] Based on the method described in the first aspect, it can be known that when the terminal device determines that the interference level on the first frequency band meets the first condition, the terminal device can monitor the downlink control channel through the main receiver, and the LP-WUR is turned off on the first frequency band. That is, the terminal device keeps the main receiver operating normally, and the LP-WUR is turned off on the first frequency band. In this way, it can be ensured that the interference level on the first frequency band meets the first condition. For example, if the terminal device is subject to large interference on the first frequency band, the terminal device can operate normally, avoiding channel saturation caused by channel blockage or damage of the LP-WUR and the inability to demodulate the signal normally, thereby reducing the impact of the interference signal on the LP-WUR and improving the stability of communication.

[0009] In one possible design, the first frequency band is the operating frequency band of the LP-WUR, or the deviation between the first frequency band and the operating frequency band of the LP-WUR satisfies a preset value. The preset value may be predefined or preconfigured. That is, the first frequency band may be the operating frequency band of the LP-WUR, or an adjacent frequency band to the operating frequency band of the LP-WUR. This ensures that the terminal device is shut down when interference is encountered in the first frequency band, thereby protecting the LP-WUR from damage.

[0010] In one possible design, the terminal device is in a connected state, and the method described in the first aspect further includes: performing detection on a first frequency band through a main receiver to obtain a first detection result. It can be understood that when the terminal device is in a connected state, the main receiver is always in an operating state, and the presence of interference and the magnitude of the interference are detected and evaluated by the main receiver. At this time, the terminal device can use the main receiver to detect and evaluate the presence of interference and the magnitude of the interference, thereby realizing real-time detection and evaluation of interference to determine whether to turn on LP-WUR in the connected state, or whether to turn on LP-WUR after entering the idle state.

[0011] In one possible design, the first detection result includes at least one of the following: a sensitivity degradation value; a received signal power value; an interference level value; or a demodulation bit error rate or block error rate. The first detection result meeting the first condition includes at least one of the following: the sensitivity degradation value is greater than a first threshold; the received signal power value is greater than a second threshold; the interference level value is greater than a third threshold; or the demodulation bit error rate or block error rate is greater than a fourth threshold. The first threshold, the second threshold, the third threshold, and the fourth threshold may be predefined or preconfigured values ​​and are not limited thereto.

[0012] In this way, the terminal device can accurately determine that the LP-WUR is subject to significant or strong interference in the first frequency band based on the first detection result and the corresponding constraint conditions. It is understood that the first detection result may also include any other parameters that may be used to characterize the degree of interference or the interference state. The first detection result that satisfies the first condition may also include any other possible constraint conditions, without limitation.

[0013] In a possible design scheme, the method described in the first aspect also includes: sending first status information to the network device, and receiving first indication information from the network device. The first status information is used to characterize that the first detection result meets the first condition; the first indication information is used to instruct the terminal device to activate the monitoring low-power wake-up signal LP-WUS in the first frequency band. That is, when the terminal device detects through the main receiver that the LP-WUR is interfered with and cannot work normally in the first frequency band, it can report the first status information to the network device so that the terminal device and the network device can synchronize their status. For example, the network device can subsequently determine not to send the LP-WUS signal in the first frequency band based on the first status information. In this way, it can avoid the network device mistakenly believing that the LP-WUR is still working normally in the first frequency band and continues to send the LP-WUS signal, resulting in a waste of spectrum resources.

[0014] In one possible design, the method described in the first aspect further includes: determining, based on the first indication information, that the LP-WUR does not monitor the LP-WUS on the first frequency band. This means displaying the indication for flexibility. Alternatively, without requiring an indication from the network device, the terminal device may directly determine to deactivate / deconfigure / not monitor the LP-WUR on the first frequency band upon detecting that the LP-WUR is unable to operate normally due to interference on the first frequency band. This reduces signaling overhead and resource waste.

[0015] In a possible design scheme, after the downlink control channel is monitored by the main receiver of the terminal device and the LP-WUR of the terminal device is turned off on the first frequency band, the method described in the first aspect also includes: determining that the second detection result meets the second condition, and turning on LP-WUR on the second frequency band. That is, the terminal device determines through the detection of the main receiver that the degree of interference on the second frequency band meets the second condition, such as the interference is weakened or disappears, etc. The terminal device can turn on LP-WUR on the second frequency band, that is, LP-WUR is in a working state. In this way, the terminal device can monitor LP-WUS through LP-WUR to trigger the main receiver to monitor the downlink control channel, such as the downlink physical control channel (PDCCH) when receiving LP-WUS, thereby reducing the power consumption of PDCCH monitoring. It can be understood that the first frequency band and the second frequency band can be the same or different, without limitation.

[0016] In one possible design, the second detection result includes at least one of the following: a sensitivity degradation value; a received signal power value; an interference level value; or a demodulation bit error rate or block error rate. The second detection result meeting the second condition includes at least one of the following: the sensitivity degradation value is less than or equal to a fifth threshold; the received signal power value is less than or equal to a sixth threshold; the interference level value is less than or equal to a seventh threshold; or the demodulation bit error rate or block error rate is less than or equal to an eighth threshold. The fifth, sixth, seventh, and eighth thresholds are predefined or preconfigured values ​​and are not limited.

[0017] In this way, the terminal device can accurately determine whether the interference to the LP-WUR in the second frequency band has been reduced or eliminated based on the second detection result and the corresponding constraint conditions. It is understood that the second detection result may also include any other parameters that may be used to characterize the degree of interference or the interference state. The second detection result that satisfies the second condition may also include any other possible constraint conditions, without limitation.

[0018] In one possible design, the second frequency band is the operating frequency band of the LP-WUR, or the deviation between the second frequency band and the operating frequency band of the LP-WUR satisfies a preset value. The preset value may be predefined or preconfigured. That is, the second frequency band may be the operating frequency band of the LP-WUR, or an adjacent frequency band to the operating frequency band of the LP-WUR. This ensures that when the terminal device can operate normally due to reduced or absent interference in the second frequency band, the LP-WUR can resume normal operation.

[0019] In a possible design scheme, the method described in the first aspect further includes: sending second status information to the network device, and receiving second indication information from the network device. The second status information is used to characterize that the second detection result meets the second condition; the second indication information is used to instruct the terminal device to activate monitoring of LP-WUS on the second frequency band. That is, when the terminal device can detect that LP-WUS can work normally despite interference on the second frequency band, it reports the second status information to the network device so that the terminal device and the network device can synchronize their status. For example, the network device can subsequently determine to resume sending LP-WUS signals on the second frequency band based on the second status information. In this way, the terminal device can trigger the main receiver to monitor the downlink control channel when receiving LP-WUS, so as to reduce the power consumption of PDCCH monitoring and improve energy saving.

[0020] In one possible design, the method described in the first aspect further includes: monitoring LP-WUS via LP-WUR on the second frequency band based on second indication information. That is, the terminal device can determine, based on an indication from the network device, whether the LP-WUR activates monitoring of the LP-WUS on the second frequency band, thereby achieving flexibility. Alternatively, without an indication from the network device, the terminal device can directly determine whether the LP-WUR activates monitoring of the LP-WUS on the second frequency band upon detecting that the interference to the LP-WUR on the second frequency band has weakened or disappeared, allowing the terminal device to resume normal operation. This can reduce signaling overhead and resource waste.

[0021] In one possible design, the downlink control channel is monitored by the main receiver of the terminal device, including: when the terminal device switches to an idle state or an inactive state, the downlink control channel, such as a paging signal, is monitored by the main receiver on the first frequency band. That is, the terminal device determines through the detection of the main receiver in the connected state that the LP-WUR is subject to strong interference on the first frequency band and cannot work normally, and the terminal device still resides in the first frequency band when entering the idle state or the inactive state. At this time, the terminal device continues to keep the main receiver working. In this way, it can be ensured that the terminal device can still monitor normally in the idle state or the inactive state under greater interference, thereby improving the stability of communication. It can be understood that at this time, the first frequency band is the common working frequency band of the main receiver and the LP-WUR.

[0022] In one possible design, the terminal device is in an idle state, and the method of the first aspect further includes: performing detection on a first frequency band via a primary receiver or an LP-WUR to obtain a first detection result. It is understood that when the terminal device is in a connected state, at least one of the primary receiver or the LP-WUR is in an operating state. At this time, the terminal device can detect and evaluate the presence and magnitude of interference via the primary receiver or the LP-WUR, thereby achieving real-time detection and evaluation of interference to determine whether to turn the LP-WUR on or off.

[0023] In one possible design, a primary receiver performs detection on a first frequency band, and when a first detection result is obtained, the first detection result includes at least one of the following: a sensitivity degradation value; a received signal power value; an interference level value; or a demodulation bit error rate or block error rate. The first detection result satisfies a first condition when at least one of the following is satisfied: the sensitivity degradation value is greater than a first threshold; the received signal power value is greater than a second threshold; the interference level value is greater than a third threshold; or the demodulation bit error rate or block error rate is greater than a fourth threshold. In this case, the first frequency band can be the LP-WUR operating frequency band, or an adjacent frequency band.

[0024] When LP-WUR is used to detect on the first frequency band and obtain the first detection result, the first detection result includes at least one of the following: sensitivity deterioration value; power value of the received signal; level value of the interference level; demodulation LP-WUS signaling error rate; or, whether the time domain synchronization or frequency domain synchronization process based on the low power synchronization signal LP-SS fails; the first detection result satisfies the first condition including at least one of the following: sensitivity deterioration value is greater than the ninth threshold; power value of the received signal is greater than the tenth threshold; level value of the interference level is greater than the eleventh threshold; LP-WUR demodulation LP-WUS signaling error rate is greater than the twelfth threshold or, LP-WUR fails in the time domain synchronization or frequency domain synchronization process based on LP-SS, to meet the needs of different scenarios. At this time, the first frequency band can be the working frequency band of LP-WUR.

[0025] Among them, the ninth threshold, the tenth threshold, the eleventh threshold, and the twelfth threshold are predefined or preconfigured values ​​and are not limited. In this way, the terminal device can accurately determine whether the LP-WUR is subject to large interference or strong interference in the first frequency band based on the first detection result and the corresponding constraint conditions. It can be understood that the first detection result can also include any other parameters that may be used to characterize the degree of interference or the interference state. The first detection result that meets the first condition can also include any other possible constraint conditions without limitation.

[0026] In a possible design scheme, the method described in the first aspect also includes: sending third state information to the network device. The third state information is used to characterize that the LP-WUR of the terminal device is turned off on the first frequency band. That is, when the terminal device detects through the main receiver or LP-WUR that the LP-WUR is interfered with and cannot work normally on the first frequency band, it can report the third state information to the network device through message (MSG) 3, small data transmission (SDT) or any other possible method to avoid entering the connection state, so that the terminal device and the network device can be synchronized. The network device can decide whether to stop sending the LP-WUS signal on the LP-WUR to avoid the network device mistakenly thinking that the LP-WUR is still working normally and continuing to send the LP-WUS signal, resulting in a waste of spectrum resources.

[0027] In one possible design scheme, after the downlink control channel is monitored by the main receiver of the terminal device and the LP-WUR of the terminal device is turned off on the first frequency band, the method described in the first aspect also includes: determining that the third detection result meets the third condition, and turning on LP-WUR on the third frequency band. The third detection result indicates the degree of interference on the third frequency band. That is, the terminal device determines through the detection of the main receiver that the degree of interference on the third frequency band meets the third condition, such as the interference is weakened or disappears, etc. The terminal device can turn on LP-WUR on the third frequency band, that is, LP-WUR is in working state. In this way, the terminal device can monitor LP-WUS through LP-WUR to wake up the main receiver to monitor the paging message when receiving LP-WUS, so as to reduce power consumption. It can be understood that the first frequency band and the third frequency band can be the same or different, and there is no limitation.

[0028] In one possible design, the third detection result includes at least one of the following: a sensitivity degradation value; a received signal power value; an interference level value; or a demodulation bit error rate or block error rate. The third detection result satisfies the third condition when at least one of the following is satisfied: the sensitivity degradation value is less than or equal to a thirteenth threshold; the received signal power value is less than or equal to a fourteenth threshold; the interference level value is less than or equal to a fifteenth threshold; or the demodulation bit error rate or block error rate is less than or equal to a sixteenth threshold. The thirteenth, fourteenth, fifteenth, and sixteenth thresholds are predefined or preconfigured values ​​and are not limited.

[0029] In this way, the terminal device can accurately determine the reduction of interference to the LP-WUR in the third frequency band based on the third detection result and the corresponding constraint condition. It is understood that the third detection result may also include any other parameters that may be used to characterize the degree of interference or the interference state. The third detection result may also include any other possible constraint conditions if it satisfies the third condition, without limitation.

[0030] In one possible design, the third frequency band is the operating frequency band of the LP-WUR, or the deviation between the third frequency band and the operating frequency band of the LP-WUR satisfies a preset value. The preset value may be predefined or preconfigured. That is, the third frequency band may be the operating frequency band of the LP-WUR, or an adjacent frequency band to the operating frequency band of the LP-WUR. This ensures that the terminal device can resume normal operation of the LP-WUR when the interference in the third frequency band is weakened or eliminated and the terminal device can operate normally.

[0031] On the second aspect, a communication method is provided. The method can be executed by a network device, or by a module applied to the network device (such as a processor, chip, or chip system, etc.), and can also be implemented by a logical node, logic module or software that can realize all or part of the network device functions. For the convenience of expression, the following introduction is taken as an example of the method being executed by a network device. The method includes: receiving first state information or third state information from a terminal device, and determining not to send a low power wake-up signal LP-WUS to the terminal device on the first frequency band based on the first state information or the third state information. The first state information is used to characterize that the first detection result meets the first condition, and the first detection result indicates the degree of interference on the first frequency band; the third state information is used to characterize that the LP-WUR of the terminal device is turned off on the first frequency band.

[0032] Based on the method described in the second aspect, it can be known that the network device may not send LP-WUS to the terminal device on the first frequency band based on the first status information or the third status information reported by the terminal device. In this way, the network device may avoid mistakenly believing that LP-WUS is still working normally on the first frequency band and continuing to send LP-WUS signals, thereby wasting spectrum resources.

[0033] In one possible design, the first detection result includes at least one of the following: a sensitivity degradation value; a received signal power value; an interference level value; or a demodulation bit error rate or block error rate. The first detection result meeting the first condition includes at least one of the following: the sensitivity degradation value being greater than a first threshold; the received signal power being greater than a second threshold; the interference level being greater than a third threshold; or the demodulation bit error rate or block error rate being greater than a fourth threshold.

[0091] For ease of understanding, the technical terms involved in the embodiments of this application are first introduced below.

[0092] 1. Radio resource control (RRC) status

[0093] In the fifth generation (5G) communication system, the RRC state may include idle, connected, and inactive. When the terminal device has no signaling and / or service data to receive or send, the terminal device may enter the idle or inactive state to reduce power consumption.

[0094] The idle state is the state in which the terminal device is not connected to the access network device. In the idle state, the terminal device can perform processes such as public land mobile network (PLMN) selection, cell selection, cell reselection and system message broadcasting.

[0095] The connected state is the state in which a terminal device enters after completing a connection with an access network device. In the connected state, the terminal device can obtain its context and key from the network to transmit service data. A terminal device can enter the connected state from the idle state or inactive state. For example, the terminal device can send a radio resource control (RRC) message to the access network device to request to establish or restore a connection with the access network device, thereby entering the connected state. Alternatively, the terminal device can also be released from the connected state to the idle state or inactive state.

[0096] The Inactive state is an intermediate state between the Connected state and the Idle state. In the Inactive state, the terminal device can delete the key but retain the terminal device context so that it can be quickly restored to the Connected state later.

[0097] It can be understood that the idle state referred to in the embodiments of the present application generally refers to the RRC idle state unless otherwise specified, the connection state referred to in the embodiments of the present application generally refers to the RRC connection state unless otherwise specified, and the inactive state referred to in the embodiments of the present application generally refers to the RRC inactive state unless otherwise specified, which can also be called the "third state".

[0098] 2. Interfering signal

[0099] Interference signals may refer to signals that damage the reception of useful signals. The 3rd Generation Partnership Project (3GPP) protocol defines interference signals in the radio frequency protocol of terminal devices according to different interference scenarios. The main interference signals include adjacent channel selectivity (ACS), in-band blocking (IBB) and out-of-band blocking (OBB) and other interference signals, without limitation. It can be understood that the size of the interference signal is much higher / much larger than the useful signal received by the terminal device, that is, the receiver sensitivity signal. For example, the ACS interference signal defined by the protocol can be more than 30 decibels (dB) higher than the sensitivity signal, while the IBB signal and OBB signal can be higher than the ACS signal.

[0100] Among them, the ACS interference signal can mainly be the new radio (NR) signal interference from the neighboring operator deployed in the same region and the same working frequency band; the IBB interference signal can mainly be the downlink signal interference from the base station in the same working frequency band; the OBB interference signal can mainly be the interference from other frequency bands or other systems.

[0101] It is understood that interference signals may come from non-target network devices, such as downlink signals from base stations, uplink signals from terminal devices in other frequency bands, or interference signals from other systems outside the operating frequency band, without limitation. Due to the mobility of terminal devices and the directionality of antennas, the interference signals experienced by terminal devices at different locations in the cell may vary. Furthermore, since terminal devices typically support multiple operating frequency bands, not all frequency bands may be affected by interference.

[0102] The interference signal can be continuous interference at the same location and in the same direction, or it can be short-term interference with a certain degree of randomness. For example, the interference levels experienced by terminal devices at different locations in the cell and facing different directions of surrounding base stations may be different. The duration of the interference signal may also be different in different scenarios. For example, if the location of the terminal device does not change, it may suffer from continuous downlink interference from the direction of a certain base station. If the interference signal of the terminal device comes from the uplink signal of other terminal devices in adjacent frequency bands, then when the uplink signal of the interfering terminal device is sent, the interference signal will disappear.

[0103] 3. Low power wake up receiver (LP-WUR)

[0104] Before the introduction of LP-WUR, terminal devices only had normal main receivers (typical receivers, also referred to as main receivers for short). The design goal of this main receiver was to be able to resist larger interference signals while receiving smaller useful signals defined by the protocol. In other words, without considering LP-WUR, normal terminal receivers, whether in connected or idle state, can operate normally in the presence of in-band and out-of-band interference signals. The interference signal can be an adjacent frequency ACS interference signal, an IBB interference signal, an OBB interference signal, etc., without limitation.

[0105] To properly demodulate small desired signals in the presence of interference, the primary receiver implementation typically requires sufficient dynamic range. This means the analog-to-digital converter (ADC) must have a sufficient number of bits. The ADC's dynamic range can generally be estimated by multiplying the number of bits by 6.02. For a 10-bit ADC, the ADC's dynamic range is approximately 60dB. Because ACS and IBB interference signals fall within the operating frequency band, band filters are unable to suppress them. These interference signals are amplified along with the desired signal in the receiver and sampled by the ADC. Some receiver implementations, such as superheterodyne IF receivers, can use channel filters to suppress ACS and IBB signals in the analog channel (before ADC sampling), reducing the ADC's dynamic range requirements. However, these channel filters typically use surface acoustic wave (SAW) filters, which are costly and not readily available in all terminal equipment architectures. Even in the zero-IF architecture commonly used in mobile communication terminals, channel filters with this high interference suppression capability are not readily available in the analog receive channel. After ADC sampling, digital domain channel filtering is usually required in the digital part. For OBB out-of-band blocking signals, frequency band filters are generally used to suppress out-of-band interference signals.

[0106] Interference signals are amplified along with the desired signal, especially in-band interference signals. Without channel filter suppression, they are directly amplified. Receivers place high demands on the linearity and dynamic range of the channel amplifiers. Sometimes, to reduce the strain on the ADC's dynamic range or to mitigate unexpectedly large interference signals exceeding protocol specifications, receivers employ fast automatic gain control (AGC). When a large interference signal arrives, the receiver channel gain is quickly reduced to ensure that the amplified interference signal does not saturate the receiving channel, preventing proper demodulation, or damage components in the receiving channel, such as the amplifier or ADC, by exceeding their maximum tolerable signal levels. For typical receivers, frequency band filters, channel filters, analog baseband filters, high-dynamic-range ADCs, baseband digital filtering, and AGC are all commonly used to minimize the impact of interference signals on the desired signal.

[0107] With the advancement of wireless communication technology, terminal devices are supporting an increasing number of features, significantly increasing implementation complexity and leading to higher power consumption. Starting with Release (R) 16, 3GPP has been researching energy conservation in terminal devices, and in Release 18, they established research projects on low-power wake-up signals (LP-WUS) and LP-WUR.

[0108] In order to reduce the power consumption of existing terminal receivers (typical receivers), the terminal device can adopt a longer sleep cycle so that it can be periodically turned on for communication, but this brings about a larger communication delay. If the terminal device can be woken up on demand, low power performance and latency requirements can be taken into account at the same time. LP-WUR can realize the on-demand wake-up function. By adding this auxiliary wake-up module to the existing terminal receiver, when there is no communication demand, the terminal receiver can be turned off or in sleep state, and only the wake-up receiver is turned on to monitor the wake-up signal and wake up the terminal receiver in time. Because LP-WUR uses simple hardware, it can reduce power consumption to the microwatt level.

[0109] During the Release 18 research phase, 3GPP evaluated three major low-power wake-up receiver architectures: RF envelope detection, superheterodyne IF detection, and zero-IF. These three receiver architectures, particularly the latter two, are widely applicable in mobile communication terminal receiver designs. However, due to the low power design requirements of the LP-WUR receiver, LP-WUR receivers must be implemented more simply, resulting in weaker channel filter rejection capabilities. Furthermore, the low power requirements of the ADC lead to a smaller bit count. For example, the 3GPP evaluation considered a 4-bit ADC to be sufficient for demodulating low-power wake-up signals. However, the low bit count of the ADC means that the LP-WUR receiver has a limited dynamic range, implying poor ability to simultaneously process small desired signals and large interference. Furthermore, the low cost of the LP-WUR filter implementation further degrades its ability to withstand large interference signals. Compared to primary receivers, which are designed for low power and low cost, the LP-WUR receiver's interference rejection capabilities are significantly lower.

[0110] Taking the example of an IBB interference signal from a terminal device, the receiver sensitivity in a 10 MHz bandwidth time division duplex (TDD) band is -97.1 dBm / 10 MHz. Under IBB interference conditions, a sensitivity drop of 6 dB is permitted, meaning a signal of -91.1 dBm / 10 MHz can be properly demodulated. In this case, the IBB interference signal can reach -44 dBm / 5 MHz or -41 dBm / 10 MHz. If the terminal device's receiver is to be able to demodulate properly despite this interference, the minimum required receiver dynamic range is -41 dBm - (-91.1 dBm) = 50.1 dB. Considering the modulated signal's peak-to-average ratio and design margin, a 60 dB dynamic range is generally required, which necessitates a 10-bit ADC.

[0111] The above-mentioned method of resisting greater interference is commonly used in the design of normal terminal receivers (typical receivers). For terminal equipment using LP-WUR, the main receiver can also resist interference signals such as ACS, IBB, and OBB defined by the protocol. That is, the main receiver of the terminal equipment supporting LP-WUS can work normally under various interference signals defined by the existing protocol, and allow a certain degree of sensitivity deterioration under interference conditions. For example, taking ACS interference as an example, under different signal bandwidths, the sensitivity (such as reference sensitivity (REFSENS)) is allowed to deteriorate by 14dB. Interference signals such as IBB and OBB can allow different degrees of sensitivity deterioration depending on the signal bandwidth, without limitation.

[0112] The low power consumption and low cost of LP-WUR mean that it has a weak ability to resist large interference signals while receiving small signals. Therefore, a certain mechanism is needed to ensure that the normal operation of LP-WUR can still be achieved while achieving energy conservation when the terminal device encounters large interference.

[0113] For LP-WUR, since the ADC may have a low bit count and lack a wide dynamic range, the analog channel's channel filter, used to suppress interference signals, may be unable to minimize in-band interference signals due to the filter's limited suppression capability. While the primary receiver can normally demodulate under interference conditions, the LP-WUR's receiving channel may experience channel saturation, preventing normal demodulation or resulting in an extremely high demodulation bit error rate. The interference signal level may even exceed the tolerance of the receiving channel components, causing damage and permanent failure of the LP-WUR.

[0114] To reduce power consumption in existing terminal receivers, LP-WUR can monitor LP-WUS and, upon detection, wake up / trigger the primary receiver to receive and process downlink control channels. For terminal devices using LP-WUR, the primary receiver is immune to protocol-defined interference signals.

[0115] However, when a terminal device is subject to strong interference signals, the LP-WUR may be damaged and unable to function properly, thus affecting energy conservation and communication stability. Therefore, how to reduce the impact of interference signals on the LP-WUR is an urgent problem to be solved.

[0116] It's understandable that terminal devices operate in both connected and idle states. Due to the randomness and potentially long-lasting nature of interference, terminal devices may encounter interference signals from surrounding areas in both connected and idle states. Furthermore, if a terminal device experiences persistent, strong interference in the connected state, it will continue to experience strong interference in the idle state, posing a significant challenge to the low-power, low-cost design of LP-WUR.

[0117] For example, if a terminal device experiences sustained interference in a connected state, after the primary receiver completes signal reception, the terminal device will enter an idle state to conserve energy, with the LP-WUR responsible for monitoring the LP-WUS signal. After the LP-WUR receives the LP-WUS signal corresponding to the terminal device, the terminal device wakes up the primary receiver, i.e., wakes up the primary receiver to monitor for paging signals. After the primary receiver receives the paging signal for the terminal device, the terminal device can initiate access to the network device.

[0118] However, at this point, the LP-WUR is unaware that the main receiver is operating under a significant interference signal. While the main receiver can demodulate normally under interference conditions, under the same interference signal conditions, once the LP-WUR enters operation, it may experience channel saturation or component damage, preventing normal demodulation. Alternatively, the demodulation error rate may be extremely high, or even the interference signal level may exceed the tolerance of the components in the receiving channel, causing component damage and permanent failure of the LP-WUR. If the LP-WUR encounters a strong interference signal in its idle state, if the channel is blocked or the components are damaged, the terminal device will not be able to receive paging signals from the network device, resulting in the terminal device being unable to connect to the network device, affecting energy conservation and communication stability.

[0119] In summary, in response to the above technical problems, the embodiments of the present application propose the following technical solutions to reduce the impact of interference signals on LP-WUR.

[0128] To facilitate understanding of the embodiments of the present application, a communication system applicable to the embodiments of the present application is first described in detail using the communication system shown in Figure 1 as an example. For example, Figure 1 is a schematic diagram of the architecture of a communication system applicable to the communication method provided in the embodiments of the present application.

[0129] As shown in FIG1 , the communication system mainly includes: network equipment and terminal equipment.

[0130] Among them, there can be multiple network devices, such as a first network device, a second network device, etc. The network device can be a device with wireless transceiver functions, or it can be a chip or chip system set in the device, located in the access network (AN) of the communication system, to provide access services for the terminal. For example, the network device can be called a radio access network device (RAN) device, which can specifically be a next-generation mobile communication system, such as a 6G access network device, such as a 6G base station, or in the next-generation mobile communication system, the network device can also have other naming methods, which are all covered within the protection scope of the embodiments of the present application, and the embodiments of the present application do not impose any limitations on this. Alternatively, the network device may include 5G, such as a gNB in ​​a new radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) of a base station in 5G, or a network node constituting a gNB, a transmission and reception point (TRP or TP), or a transmission measurement function (TMF), such as a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), a radio unit (RU), an RSU with base station functions, a wired access gateway, or a 5G core network element.

The RU may be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It is understood that the network device may be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU may be classified as a network device in the access network RAN, or the CU may be classified as a network device in the core network CN, without limitation herein.

[0132] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU.

Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0133] In the embodiments of the present application, the form of the network device is not limited. The device used to implement the function of the network device can be a network device; it can also be a device that can support the network device to implement the function, such as a chip system. The device can be installed in the network device or used in conjunction with the network device.

[0134] The terminal device may be a device or module that accesses the above-mentioned communication system and has corresponding communication functions. The terminal device may be one or more, such as a first terminal device, a second terminal device, a third terminal device, etc. The terminal device may be a terminal device with transceiver functions, or may be a chip or chip system provided in the terminal device. The terminal device may also be referred to as user equipment (UE), access terminal device, subscriber unit (subscriber unit), user station, mobile station (MS), mobile station, remote station, remote terminal device, mobile device, user terminal device, terminal device, wireless communication device, user agent or user device. The terminal device in the embodiments of the present application can be a mobile phone, a cellular phone, a smart phone, a tablet computer, a wireless data card, a personal digital assistant (PDA), a wireless modem, a handheld device (handset), a laptop computer, a machine type communication (MTC) terminal device, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a smart home device (for example, a refrigerator, a television, an air conditioner, an electric meter, etc.), an intelligent robot, a robotic arm, a workshop device, a wireless terminal device in unmanned driving, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical care, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a smart home, etc. The terminal device of the present application may also be a vehicle-mounted module, a vehicle-mounted module, a vehicle-mounted component, a vehicle-mounted chip or a vehicle-mounted unit, a transport vehicle with wireless communication function, or a communication module that is built into a vehicle as one or more components or units. The terminal device may also be other devices with terminal device functions. For example, the terminal device may also be a device that functions as a terminal device in D2D communication.

[0135] The embodiments of the present application do not limit the form factor of a terminal device or network device. The apparatus used to implement the functions of a terminal device or network device can be a terminal device or network device; it can also be a device capable of supporting the terminal device or network device in implementing the functions, such as a system-on-chip. The apparatus can be installed in the terminal device or network device or used in conjunction with the terminal device or network device. When the apparatus used to implement the functions of a terminal device or network device is a device capable of supporting the terminal device or network device in implementing the functions, receiving / sending can be understood as input / output, that is, the apparatus communicates with other components of the terminal device or network device. In the embodiments of the present application, the system-on-chip can be composed of a chip or can include a chip and other discrete components. The terminal device is typically provided with a communication module, circuit, or chip that performs the corresponding communication functions. The terminal device can also be configured with program instructions for performing the corresponding communication functions. In the embodiments of the present application, the processing performed by a single execution entity can also be divided into multiple execution entities, which can be logically and / or physically separated. For example, the processing performed by the network device can be divided into at least one of the CU, DU, and RU.

[0136] In this communication system, when a terminal device determines that the level of interference in a first frequency band meets a first condition, the terminal device can monitor the downlink control channel via the primary receiver while the LP-WUR is turned off in the first frequency band. That is, the terminal device maintains normal operation of the primary receiver while the LP-WUR is turned off in the first frequency band. This ensures that the level of interference in the first frequency band meets the first condition. For example, if the terminal device experiences significant interference in the first frequency band, the terminal device can continue to operate normally, preventing channel saturation and the inability to properly demodulate signals due to channel blockage or damage to the LP-WUR. This reduces the impact of interference signals on the LP-WUR and improves communication stability.

[0137] It can be understood that FIG1 is only a simplified schematic diagram for ease of understanding, and the communication system may also include other network devices and / or other terminal devices, which are not shown in FIG1 .

[0138] For ease of understanding, the communication method provided in the embodiment of the present application will be specifically described below with reference to FIG2 .

[0139] 2 is a flow chart of a communication method provided in an embodiment of the present application. The method can be applied to the communication between the network device and the terminal device in the above communication system.

[0140] S201: The terminal device determines that a first detection result meets a first condition.

[0141] The first detection result may indicate a degree of interference on a first frequency band. The first frequency band may be an operating frequency band of the LP-WUR, or a frequency deviation value between the first frequency band and the operating frequency band of the LP-WUR satisfies a preset value. In other words, the first frequency band may be an operating frequency band of the LP-WUR, or an adjacent / similar frequency band to the operating frequency band of the LP-WUR. The deviation value may be predefined or preconfigured and is not limited.

[0142] When the terminal device determines that the first detection result satisfies the first condition, it can be determined that the LP-WUR is unable to operate normally due to interference in the first frequency band, or in other words, the LP-WUR in the first frequency band cannot operate normally under the interference intensity. This judgment condition or judgment threshold depends on the terminal device implementation and can be determined by the terminal device itself; or it can be specified in the form of performance indicators in the standard / protocol. The following two cases are used as examples to specifically describe how the terminal device determines that the first detection result satisfies the first condition.

[0143] Case 1: The terminal device is in the connected state.

[0144] The terminal device can perform detection on the first frequency band through the main receiver to obtain a first detection result.

[0145] It can be understood that when the terminal device is in a connected state, the main receiver is always in working state, and the terminal device's radio resource management (RRM), radio link monitoring (RLM), beam failure detection (BFD), channel status information (CSI) and other measurements are still completed by the main receiver. At this time, the main receiver can be used to detect and evaluate whether there is an interference signal and the size of the interference.

[0146] The first detection result may include at least one of the following: a sensitivity degradation value; a power value of a received signal; a level value of an interference level; or a demodulation bit error rate or a block error rate.

[0147] The first detection result meeting the first condition may include at least one of the following: a sensitivity degradation value greater than a first threshold; a received signal power value greater than a second threshold; an interference level greater than a third threshold; or a demodulation bit error rate or block error rate greater than a fourth threshold. This is described in detail below.

[0148] (1) Sensitivity deterioration value.

[0149] Sensitivity degradation refers to the degradation of reception performance, whereby the ability to receive useful signals on certain RF channels is significantly reduced due to external interference. In other words, when a terminal device is subject to interference, its sensitivity will deteriorate to a certain extent.

[0150] When the terminal device detects interference in the first frequency band through the primary receiver, it can detect the sensitivity degradation value of the primary receiver. If the terminal device determines that the sensitivity degradation of the primary receiver exceeds the first threshold, it can be determined that strong or large interference exists in the first frequency band.

[0151] The first threshold may be predefined or preconfigured, and is not limited. For example, the primary receiver sensitivity deterioration exceeds a protocol / standard defined value, such as 14dB for ACS, or a preset threshold, or a network preconfigured value, such as an interference level.

[0152] (2) The power of the received signal.

[0153] The power of the received signal may refer to the total power within the receiving bandwidth, including useful signals, interference signals and background noise. The main receiver may count / detect the power of the received signal in the receiving channel in the first frequency band, such as the received signal strength indicator (RSSI), signal to interference plus noise ratio (SINR), reference signal receiving power (RSRP), or any other parameter that can characterize the power of the received signal, without limitation. If the terminal device determines that the power of the received signal is greater than the second threshold, it may be considered that there is strong interference or greater interference in the first frequency band. The second threshold may be predefined or preconfigured, without limitation.

[0154] For example, on the first frequency band, the primary receiver can measure the power within the receiving channel in the digital baseband. For example, the primary receiver can perform RSSI measurement. When the terminal device determines that the RSSI exceeds a value defined by the protocol / standard, a preset threshold, or a network preconfigured value, it can be determined that strong or significant interference exists on the first frequency band.

[0155] The time-frequency resources for RSSI measurement can be configured by the network device or defaulted to the time-frequency location of the LP-WUS within the cell bandwidth. It is understood that the network device may perform interference avoidance for the time-frequency location where the LP-WUS is transmitted. Therefore, the interference at the LP-WUS time-frequency location may be different from that at other locations and is not limited. The time-frequency resources for RSSI measurement can also be the offset location frequency point and bandwidth of interference signals such as ACS, IBB, and OBB as defined by the protocol / standard, and are not limited.

[0156] For another example, the main receiver can adjust the channel frequency within the same working frequency band as the main receiver and LP-WUR (i.e., the above-mentioned first frequency band), or perform power statistics or RSSI measurements on the adjacent frequency band of the working frequency band of LP-WUR (i.e., the above-mentioned first frequency band) according to a certain bandwidth to obtain a measurement value. When the measurement value exceeds the protocol / standard defined value, or the preset threshold value, or the network pre-configured value, it can be considered that there is strong interference or large interference in the first frequency band. It can be understood that based on this method, the network device needs to configure the measurement target for the terminal device to enable the main receiver of the terminal device to measure the RSSI and report based on the RSSI for a specified time-frequency position, such as a specified bandwidth range and symbol position, without limitation.

[0157] (3) The level value of the interference level.

[0158] The interference level can represent the magnitude of the interference signal. The primary receiver can detect the interference level in the first frequency band. When the terminal device determines that the interference level is greater than a third threshold, it can be considered that strong or significant interference is occurring in the first frequency band. The third threshold can be predefined or preconfigured and is not limited.

[0159] (4) The demodulation bit error rate or block error rate is greater than the fourth threshold.

[0160] The bit error rate may refer to the rate of erroneous bits after demodulation by the primary receiver; the block error rate may refer to the percentage of erroneous blocks among all transmitted blocks after demodulation by the primary receiver. The primary receiver may detect the demodulation bit error rate or block error rate on the first frequency band. When the terminal device determines that the demodulation bit error rate or block error rate is greater than a fourth threshold, it may be considered that strong or significant interference is present on the first frequency band. The fourth threshold may be predefined or preconfigured and is not limited.

[0161] It can be understood that the first detection result shown above is only an example, and the first detection result may also include any other parameters that may be used to characterize the degree of interference or the state of interference, without limitation. The first detection result that satisfies the first condition may also include any other possible constraint conditions, without limitation. The main receiver may also detect the interference signal and evaluate the interference size in the first frequency band in any other possible way, without limitation. For example, the main receiver may perform AGC. If the channel gain of the main receiver is reduced, the terminal device determines that the sensitivity deterioration of the main receiver exceeds a predefined or preconfigured value, or the main receiver cannot demodulate normally, or the demodulation bit error rate of the main receiver increases significantly, etc., then it can be considered that there is strong interference or large interference in the first frequency band.

[0162] Case 2: The terminal device is in idle state.

[0163] It is understood that when the terminal device is in an idle state, at least one of the main receiver or the LP-WUR is in an active state. Therefore, the terminal device can perform detection on the first frequency band through the main receiver or the LP-WUR to obtain a first detection result.

[0164] When the terminal device performs detection on the first frequency band through the main receiver and obtains a first detection result, the first detection result may include at least one of the following: a sensitivity deterioration value; a power value of the received signal; a level value of the interference level; or a demodulation bit error rate or block error rate.

[0165] The first detection result meeting the first condition may include at least one of the following: a sensitivity degradation value greater than a first threshold; a received signal power value greater than a second threshold; an interference level greater than a third threshold; or a demodulation bit error rate or block error rate greater than a fourth threshold. It is understood that the details of these conditions can be found in the description of the aforementioned situation 1 and are omitted here.

[0166] When the terminal device performs detection on the first frequency band through LP-WUR and obtains a first detection result, the first detection result may include at least one of the following: a sensitivity deterioration value; a power value of the received signal; a level value of the interference level; a demodulated LP-WUS signaling error rate; or whether the time domain synchronization or frequency domain synchronization process based on the low power synchronization signal LP-SS fails.

[0167] The first detection result that satisfies the first condition may include at least one of the following: the sensitivity deterioration value is greater than the ninth threshold; the power value of the received signal is greater than the tenth threshold; the level value of the interference level is greater than the eleventh threshold; the LP-WUR demodulation LP-WUS signaling error rate is greater than the twelfth threshold; or, the LP-WUR time domain synchronization or frequency domain synchronization process based on LP-SS fails.

[0168] For the relevant description of the sensitivity degradation value, the power value of the received signal, the level value of the interference level, and the corresponding constraints, refer to the relevant description of Case 1 in the above step S201. The ninth threshold, the tenth threshold, and the eleventh threshold may be predefined or preconfigured and are not limited.

[0169] It is understandable that the time-frequency resources for interference measurement performed by the terminal device through LP-WUR may include at least one of the following: the time-frequency resources of the LP-WUS located by the terminal device, the time-frequency resources of the LP-SS located by the terminal device, or the time-frequency resources configured by the network device, etc., without limitation. The terminal device can detect and evaluate interference based on one time domain resource, or based on multiple time domain resources. For example, the terminal device can detect and evaluate interference based on filtering of measurement results of multiple time domain resources, without limitation.

[0170] The following describes in detail the LP-WUR demodulation LP-WUS signaling error rate and whether the time domain synchronization or frequency domain synchronization process based on the low power synchronization signal LP-SS fails.

[0171] (1) LP-WUR demodulation LP-WUS signaling error rate.

[0172] The error rate for demodulating LP-WUS signaling can be used to indicate whether the LP-WUS is properly demodulating. Error rates can include missed detection rates and false detection rates, without limitation. The missed detection rate indicates the percentage of instances where the LP-WUR fails to correctly identify or detect a real target or anomaly when demodulating LP-WUS signaling. The false detection rate indicates the percentage of instances where an erroneous bit is mistakenly identified as a correct bit when demodulating LP-WUS signaling.

[0173] The primary receiver can demodulate LP-WUS signaling on the first frequency band to obtain a demodulated LP-WUS signaling error rate. When the terminal device determines that the LP-WUR demodulated LP-WUS signaling error rate is greater than a twelfth threshold, it can be considered that there is strong or significant interference on the first frequency band. The twelfth threshold can be predefined or preconfigured and is not limited.

[0174] (2) Whether the time domain synchronization or frequency domain synchronization process based on the low power synchronization signal LP-SS fails.

[0175] LP-SS can be used for downlink synchronization between network devices and LP-WUR, namely downlink time domain synchronization and downlink frequency domain synchronization. If the terminal device determines that the LP-WUR and network device have failed in the time domain synchronization or frequency domain synchronization process based on LP-SS, it can be considered that there is strong or significant interference on the first frequency band. LP-SS can also be used as a reference signal for channel estimation or channel detection, etc., without limitation.

[0176] It can be understood that the first detection result shown above is only an example, and the first detection result may also include any other parameters that may be used to characterize the degree of interference or the state of interference, without limitation. The first detection result that meets the first condition may also include any other possible constraints, without limitation. LP-WUR can also detect interference signals and evaluate the size of interference in the first frequency band in any other possible way, without limitation. For example, LP-WUR can perform AGC, and the terminal device can determine whether the LP-WUR performs AGC to play a control role. If the terminal device determines that the LP-WUR does not play a control role after performing AGC, it can be considered that there is strong interference or large interference in the first frequency band.

[0177] It can be understood that in the embodiment of the present application, the naming of "threshold" is only an example, and "threshold" can also be replaced by any other possible naming such as "value", "threshold value", etc., without limitation; the naming of "detection result" is only an example, and "detection result" can also be replaced by any other possible naming such as "measurement result", "interference measurement result", etc., without limitation.

[0178] S202, the terminal device monitors the downlink control channel through the main receiver of the terminal device, and the LP-WUR of the terminal device is turned off in the first frequency band.

[0179] That is, on the first frequency band, the main receiver is in operation and the LP-WUR is in shutdown. The LP-WUR being in shutdown on the first frequency band can be understood as: if the LP-WUR was originally in operation, then the LP-WUR is shut down on the first frequency band; if the LP-WUR was originally in shutdown, then the LP-WUR does not turn on or remains shut down on the first frequency band.

[0180] If the terminal device is in a connected state, communication between the terminal device and the network device is normal. The terminal device monitors the downlink control channel through the primary receiver, which means that the terminal device monitors the PDCCH through the primary receiver. The terminal device can also receive downlink signals from the network device through the primary receiver, such as the physical downlink shared channel (PDSCH) and synchronization signaling block (SSB), without limitation.

[0181] If the terminal is in an idle state, the terminal device may monitor the downlink control channel through the main receiver: the terminal device may monitor the paging signal through the main receiver, and after the main receiver receives the paging signal sent by the network device to the terminal device, the terminal device may initiate an access process to the network device.

[0182] In combination with the above introduction, in a possible design solution, the above method embodiment may further include:

[0183] S202a: The terminal device sends the first status information or the third status information to the network device. Correspondingly, the network device receives the first status information or the third status information from the terminal device.

[0184] S202b: The network device determines not to send a low power consumption wake-up signal LP-WUS to the terminal device in the first frequency band according to the first state information or the third state information.

[0185] The following is a detailed introduction.

[0186] Based on the above situation 1:

[0187] The terminal device sends the first status information to the network device. Correspondingly, the network device receives the first status information from the terminal device.

[0188] The network device determines, based on the first state information, not to send a low power consumption wake-up signal LP-WUS to the terminal device in the first frequency band.

[0189] In a possible design solution, the above method embodiment may further include:

[0190] The network device sends the first indication information to the terminal device according to the first status information. Correspondingly, the terminal device receives the first indication information from the network device.

[0191] The terminal device determines, based on the first indication information, that the LP-WUR does not monitor the LP-WUS in the first frequency band.

[0192] Among them, the first status information can be used to characterize that the first detection result meets the first condition, and the first detection result can indicate the degree of interference on the first frequency band. That is, when the terminal device detects through the main receiver that there is strong interference on the first frequency band, and the LP-WUR cannot work normally under the interference intensity, the terminal device can report the first status information to the network device to inform the network device: on the first frequency band, LP-WUR cannot work normally under the interference intensity. The first status information may include: information about the interfered working frequency band and status information. The information about the interfered working frequency band may include the first frequency band, and the status information may indicate that the LP-WUR cannot work normally. It can be understood that the first status information may also include any other possible parameters or signaling, without limitation.

[0193] The network device may not send LP-WUS to the terminal device on the first frequency band based on the first status information reported by the terminal device. At the same time, the network device may send first indication information to the terminal device, which may be used to instruct the terminal device to deactivate monitoring / deconfigure monitoring / not monitor LP-WUS on the first frequency band. The terminal device may determine that LP-WUR is to be deactivated / deconfigured / not monitored on the first frequency band based on the first indication information, i.e., display the indication, thereby achieving flexibility.

[0194] At this point, the network device can send PDCCH to the terminal device according to the normal process, and the terminal device can monitor PDCCH according to the normal process; in other words, the main receiver remains in the working state, and the LP-WUR is in the off state (i.e., closed or not turned on). In this way, the terminal device and the network device can synchronize their states, which can prevent the network device from mistakenly believing that the LP-WUR is still working normally on the first frequency band and continuing to send LP-WUS signals, resulting in a waste of spectrum resources.

[0195] It can be understood that the terminal device can also do without the instruction of the network device. When it is detected that LP-WUR is interfered with and cannot work normally in the first frequency band, it can directly determine that LP-WUR deactivates monitoring / deconfigures monitoring / does not monitor LP-WUS in the first frequency band. In this way, signaling overhead can be reduced and resource waste can be reduced.

[0196] Based on the above situation 2: In a possible design solution, the above method embodiment may further include:

[0197] The terminal device sends the third status information to the network device. Correspondingly, the network device receives the third status information from the terminal device.

[0198] Among them, the third state information can be used to represent that the LP-WUR of the terminal device is turned off in the first frequency band.

[0199] The network device determines, based on the third state information, not to send the low power consumption wake-up signal LP-WUS to the terminal device in the first frequency band.

[0200] That is, when the terminal device detects strong interference in the first frequency band through the main receiver or LP-WUR, and the LP-WUR cannot work normally under the interference intensity, the terminal device can report the third state information to the network device through message (MSG) 3, small data transmission (SDT) or any other possible method to avoid entering the connection state, so as to inform the network device: on the first frequency band, LP-WUR cannot work normally under the interference intensity. The third state information may include: information about the interfered working frequency band and status information. The information about the interfered working frequency band may include the first frequency band, and the status information may indicate that LP-WUR cannot work normally. It can be understood that the third state information may also include any other possible parameters or signaling, without limitation.

[0201] The network device can determine to stop sending LP-WUS to the terminal device on the first frequency band based on the third state information reported by the terminal device. At this time, the network device can send PDCCH to the terminal device according to the normal process, and the terminal device can monitor PDCCH according to the normal process; in other words, the main receiver remains in the working state, and the LP-WUR is in the off state (that is, turned off or not turned on). In this way, the terminal device and the network device can synchronize their states, which can prevent the network device from mistakenly thinking that the LP-WUR is still working normally and continuing to send LP-WUS signals, resulting in a waste of spectrum resources.

[0202] At this time, in this situation 2, the terminal device can directly determine to deactivate / deconfigure / not monitor LP-WUS on the first frequency band when it detects that LP-WUR is interfered with and cannot work normally on the first frequency band without the instruction of the network device. In this way, signaling overhead and resource waste can be reduced.

[0203] It is understood that after receiving the third status information, the network device may also send indication information to the terminal device, such as indication information #a. Indication information #a can be used to instruct the terminal device to deactivate / deconfigure monitoring of LP-WUS in the first frequency band. The terminal device can determine, based on the indication information #a, whether to deactivate / deconfigure / not monitor LP-WUS in the first frequency band using the LP-WUR, i.e., display the indication, thereby achieving flexibility. It is understood that the indication information #a can be carried in MSG2 or any other possible information, without limitation.

[0204] It will be understood that the naming of the first state information described above is merely an example, and the first state information may be replaced by any other possible naming, such as first interference state information, without limitation. The naming of the third state information described above is merely an example, and the third state information may be replaced by any other possible naming, such as third interference state information, without limitation. The naming of the first indication information described above is merely an example, and the first indication information may be replaced by any other possible naming, such as indication information #1, without limitation.

[0205] In summary, when the terminal device determines that the interference level on the first frequency band meets the first condition, the terminal device can monitor the downlink control channel through the main receiver, while the LP-WUR is turned off on the first frequency band. That is, the terminal device maintains the normal operation of the main receiver, and the LP-WUR is turned off on the first frequency band. In this way, it can be ensured that the interference level on the first frequency band meets the first condition. For example, if the terminal device is subject to significant interference on the first frequency band, the terminal device can operate normally, avoiding channel saturation caused by channel blockage or damage of the LP-WUR and the inability to demodulate the signal normally, thereby reducing the impact of the interference signal on the LP-WUR and improving the stability of communication.

[0206] In combination with the above embodiment, based on the above situation 1, in a possible design scheme, after the terminal device monitors the downlink control channel through the main receiver of the terminal device and the LP-WUR of the terminal device is turned off on the first frequency band, the above method may further include:

[0207] The terminal device determines that the second detection result meets the second condition.

[0208] The terminal device turns on LP-WUR in the second frequency band.

[0209] The second detection result may indicate the degree of interference on the second frequency band. The second frequency band may be the operating frequency band of the LP-WUR, or the frequency deviation value between the second frequency band and the operating frequency band of the LP-WUR may meet a preset value. In other words, the second frequency band may be the operating frequency band of the LP-WUR, or an adjacent / similar frequency band to the operating frequency band of the LP-WUR. The deviation value may be predefined or preconfigured and is not limited.

[0210] When the terminal device determines, through the primary receiver, that the second detection result satisfies the second condition, it can be determined that the interference experienced by the LP-WUR in the second frequency band has weakened or disappeared, and the LP-WUR can resume normal operation. In other words, the LP-WUR in the second frequency band can operate normally under the interference intensity. This determination condition or threshold depends on the terminal device implementation and can be determined by the terminal device itself or specified as a performance indicator in the standard / protocol. The following details how the terminal device determines that the second detection result satisfies the second condition.

[0211] The second detection result may include at least one of the following: a sensitivity degradation value; a power value of a received signal; a level value of an interference level; or a demodulation bit error rate or a block error rate.

[0212] The second detection result satisfying the second condition may include at least one of the following: the sensitivity deterioration value is less than or equal to the fifth threshold; the power value of the received signal is less than or equal to the sixth threshold; the level value of the interference level is less than or equal to the seventh threshold; or the demodulation bit error rate or block error rate is less than or equal to the eighth threshold.

[0213] It is understood that the second detection result, and the second detection result satisfying the second condition, are similar to the first detection result and the first detection result satisfying the first condition in Case 1 in step S201 above, and can be understood with reference to them and will not be further described. The fifth, sixth, seventh, and eighth thresholds may be predefined or preconfigured and are not limited thereto.

[0214] The fifth threshold value may be the same as or different from the first threshold value mentioned above, without limitation; the sixth threshold value may be the same as or different from the second threshold value mentioned above, without limitation; the seventh threshold value may be the same as or different from the third threshold value mentioned above, without limitation; the eighth threshold value may be the same as or different from the fourth threshold value mentioned above, without limitation.

[0215] It will be understood that the second detection result shown above is only an example, and the second detection result may also include any other parameters that may be used to characterize the interference level or interference state, without limitation. The second detection result that satisfies the second condition may also include any other possible constraints, without limitation. The primary receiver may also detect the interference signal and assess the interference magnitude in the second frequency band by any other possible means, without limitation.

[0216] When the terminal device determines that the LP-WUR is able to resume normal operation due to reduced interference in the second frequency band, the terminal device can turn on the LP-WUR in the second frequency band, that is, the LP-WUR is in an operating state in the second frequency band. At this time, the LP-WUR can monitor the LP-WUS signal. After the LP-WUR receives the LP-WUS signal sent by the network device to the terminal device, it can trigger the main receiver to monitor the PDCCH. In this way, the power consumption of PDCCH monitoring can be reduced, and the energy saving effect can be improved.

[0217] It can be understood that the first frequency band and the second frequency band can be the same or different, without limitation. For example, if the first frequency band and the second frequency band are the same frequency band, at this time, the interference signal received by the terminal device can be the uplink signal of other terminal devices in the adjacent frequency band of the first frequency band / second frequency band. When the uplink signal of the other terminal device is sent, the interference signal disappears or weakens, and the terminal device can turn on LP-WUR on the first frequency band / second frequency band; if the first frequency band and the second frequency band are different frequency bands, at this time, the interference received by LP-WUR when switching from the first frequency band to the second frequency band is weakened or the interference disappears, and the terminal device can re-enable LP-WUR on the second frequency band.

[0218] Based on the above scenario 1, in one possible design, after the network device determines, based on the first state information, not to send the low power wake-up signal LP-WUS to the terminal device on the first frequency band, the method may further include:

[0219] The terminal device sends the second status information to the network device. Correspondingly, the network device receives the second status information from the terminal device.

[0220] The network device sends the LP-WUS to the terminal device on the second frequency band according to the second status information.

[0221] The network device sends the second indication information to the terminal device according to the second status information. Correspondingly, the terminal device receives the second indication information from the network device.

[0222] Among them, the second state information can be used to characterize that the second detection result meets the second condition, and the second detection result can indicate the degree of interference on the second frequency band. That is, when the terminal device finds through the detection of the main receiver that the interference on the second frequency band is weakened or disappears, and the LP-WUR can work normally under the interference intensity, the terminal device can report the second state information to the network device to inform the network device: on the second frequency band, LP-WUR can work normally under the interference intensity. The second state information may include: information and state information of the interfered working frequency band. The information of the interfered working frequency band may include the second frequency band, and the state information may indicate that the LP-WUR can work normally. It can be understood that the second state information may also include any other possible parameters or signaling, without limitation.

[0223] The network device can send LP-WUS to the terminal device on the second frequency band based on the second status information reported by the terminal device. At the same time, the network device can send second indication information to the terminal device, and the second indication information can be used to instruct the terminal device to activate monitoring / configure monitoring of LP-WUS on the second frequency band. The terminal device can activate monitoring / configure monitoring of LP-WUS through LP-WUR on the second frequency band based on the second indication information, that is, display the indication to achieve flexibility. In other words, the network device can send PDCCH to the terminal device according to the LP-WUS process, and the terminal device monitors the LP-WUS signal and triggers PDCCH monitoring according to the LP-WUS process.

[0224] It can be understood that the terminal device can also do without the instruction of the network device. When it is detected that the LP-WUR can work normally due to the weakened or disappeared interference in the second frequency band, it can directly determine that the LP-WUR activates monitoring / configures monitoring of LP-WUS in the second frequency band. In this way, signaling overhead can be reduced and resource waste can be reduced.

[0225] It will be understood that the naming of the second state information described above is merely an example, and the second state information may be replaced by any other possible naming, such as second interference state information, without limitation. The naming of the second indication information described above is merely an example, and the second indication information may be replaced by any other possible naming, such as indication information #2, without limitation.

[0226] In one possible design scheme, the terminal device monitors the downlink control channel through the main receiver of the terminal device, including: when the terminal device switches to an idle state or an inactive state, the terminal device monitors the downlink control channel through the main receiver on the first frequency band.

[0227] That is, in the connected state, the terminal device detects through the primary receiver that strong interference exists in the time-frequency resources corresponding to the LP-WUS in the first frequency band. If the terminal device transitions from the connected state to the idle or inactive state while still residing in the first frequency band, the terminal device can maintain the primary receiver in an active state. That is, the terminal device monitors paging messages on the first frequency band through the primary receiver, while the LP-WUR remains in an inactive state. It is understood that in this case, the first frequency band can be a common operating frequency band for the primary receiver and the LP-WUR.

[0228] Based on the above scenario 2, in one possible design, after the downlink control channel is monitored by the primary receiver of the terminal device and the LP-WUR of the terminal device is turned off in the first frequency band, the above method may further include:

[0229] The terminal device determines that the third detection result meets the third condition.

[0230] The terminal device turns on LP-WUR on the third frequency band.

[0231] The third detection result may indicate the degree of interference on the third frequency band. The third frequency band may be the operating frequency band of the LP-WUR, or the frequency deviation value between the third frequency band and the operating frequency band of the LP-WUR satisfies a preset value. In other words, the third frequency band may be the operating frequency band of the LP-WUR, or an adjacent / similar frequency band to the operating frequency band of the LP-WUR. The deviation value may be predefined or preconfigured and is not limited.

[0232] When the terminal device determines, through the primary receiver, that the third detection result satisfies the third condition, it can be determined that the interference experienced by the LP-WUR in the third frequency band has weakened or disappeared, and the LP-WUR can resume normal operation. In other words, the LP-WUR in the third frequency band can operate normally under the interference intensity. This determination condition or threshold depends on the terminal device implementation and can be determined by the terminal device itself or specified as a performance indicator in the standard / protocol. The following details how the terminal device determines that the third detection result satisfies the third condition.

[0233] The third detection result may include at least one of the following: a sensitivity degradation value; a power value of a received signal; a level value of an interference level; or a demodulation bit error rate or a block error rate.

[0234] The third detection result satisfying the third condition may include at least one of the following: the sensitivity deterioration value is less than or equal to the thirteenth threshold; the power value of the received signal is less than or equal to the fourteenth threshold; the level value of the interference level is less than or equal to the fifteenth threshold; or the demodulation bit error rate or block error rate is less than or equal to the sixteenth threshold.

[0235] It is understood that the third detection result and the third detection result satisfying the third condition are similar to the first detection result and the first detection result satisfying the first condition in Case 1 of step S201 above, and can be used for reference and understanding, and is not further described. The thirteenth threshold, the fourteenth threshold, the fifteenth threshold, and the sixteenth threshold can be predefined or preconfigured and are not limited.

[0236] The thirteenth threshold value may be the same as or different from the first threshold value mentioned above, without limitation; the fourteenth threshold value may be the same as or different from the second threshold value mentioned above, without limitation; the fifteenth threshold value may be the same as or different from the third threshold value mentioned above, without limitation; the sixteenth threshold value may be the same as or different from the fourth threshold value mentioned above, without limitation.

[0237] It will be understood that the third detection result shown above is merely an example, and the third detection result may also include any other parameter that may be used to characterize the degree of interference or the interference state, without limitation. The third detection result that satisfies the third condition may also include any other possible constraint conditions, without limitation. The primary receiver may also detect the interference signal and assess the interference magnitude in the third frequency band by any other possible means, without limitation.

[0238] When the terminal device determines that the interference to the LP-WUR on the third frequency band has weakened or disappeared and the terminal device can resume normal operation, the terminal device can turn on the LP-WUR on the third frequency band, that is, the LP-WUR is in an operating state on the third frequency band. At this time, the LP-WUR can monitor the LP-WUS signal. After the LP-WUR receives the LP-WUS signal sent by the network device to the terminal device, it can wake up the main receiver to monitor the paging signal. In this way, the terminal device can be woken up on demand, which can take into account both low power consumption performance and latency requirements.

[0239] It can be understood that the first frequency band and the third frequency band can be the same or different, without limitation. For example, if the first frequency band and the third frequency band are the same frequency band, at this time, the interference signal received by the terminal device can be the uplink signal of other terminal devices in the adjacent frequency band of the first frequency band / third frequency band. When the uplink signal of the other terminal device is sent, the interference signal disappears or weakens, and the terminal device can turn on LP-WUR on the first frequency band / third frequency band; if the first frequency band and the third frequency band are different frequency bands, at this time, the interference received by LP-WUR when switching from the first frequency band to the third frequency band is weakened or the interference disappears, and the terminal device can re-enable LP-WUR on the third frequency band.

[0240] It is understandable that the terminal device may also choose to have the primary receiver operate during this idle state period, thereby reducing the signaling overhead of the terminal device and the network device, without limitation.

[0241] Based on the above situation 2, in a possible design scheme, after the network device determines, based on the third state information, not to send the low power wake-up signal LP-WUS to the terminal device in the first frequency band, the above method may further include:

[0242] The terminal device sends the fourth status information to the network device. Correspondingly, the network device receives the fourth status information from the terminal device.

[0243] The network device sends the LP-WUS to the terminal device on the third frequency band according to the fourth state information.

[0244] The fourth state information may be used to indicate that the third detection result satisfies the third condition, and the third detection result may indicate the degree of interference in the third frequency band.

[0245] That is, when the terminal device detects strong interference in the third frequency band through the detection of the main receiver, and LP-WUR cannot work normally under the interference intensity, the terminal device can report the fourth status information to the network device through MSG3, SDT or any other possible method to inform the network device: on the third frequency band, LP-WUR can work normally under the interference intensity, that is, request the network device to enable LP-WUS. The fourth status information may include: information about the interfered working frequency band and status information. The information about the interfered working frequency band may include the third frequency band, and the status information may indicate that LP-WUR can work normally. It can be understood that the fourth status information may also include any other possible parameters or signaling, without limitation.

[0246] The network device can send LP-WUS to the terminal device on the third frequency band based on the fourth status information reported by the terminal device. In this situation 2, the terminal device can directly determine whether to deactivate monitoring / deconfigure monitoring / not monitor LP-WUS on the first frequency band when it detects that LP-WUR is interfered with and cannot work normally on the first frequency band without the instruction of the network device. In this way, signaling overhead and resource waste can be reduced. For example, if the main receiver is able to demodulate LP-WUS and the network device has started to send LP-WUS signals, LP-WUR can also be directly turned on without confirmation or instruction from the network device.

[0247] It is understandable that the network device may also send an indication message to the terminal device after receiving the third status information, such as indication message #b. Indication message #b may be used to instruct the terminal device to activate monitoring / configure monitoring of LP-WUS on the first frequency band. The terminal device may determine that LP-WUR activates monitoring / configures monitoring of LP-WUS on the first frequency band based on the indication message #b, i.e., displays the indication to achieve flexibility. It is understandable that the indication message #b may be carried in MSG2 or any other possible information without limitation. In this way, the terminal device and the network device can synchronize their status, which can prevent the network device from mistakenly believing that LP-WUR is still working normally and continuously sending LP-WUS signals, resulting in a waste of spectrum resources.

[0248] It can be understood that the above naming of the second state information is only an example, and the second state information can also be replaced by any other possible naming, such as second interference state information, etc., without limitation.

[0249] It can be understood that the naming of the above-mentioned main receiver is only an example, and the main receiver can also be replaced by any other possible name, such as main receiver, etc., without limitation; the naming of the above-mentioned LP-WUR is only an example, and LP-WUR can also be replaced by any other possible name, such as auxiliary receiver, etc., without limitation.
