[0026] The technical solutions of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0027] It should be noted that, in this disclosure, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0028] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0029] In the description of this disclosure, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "more than one" means two or more.

[0030] In mobile communication systems, terminals introduce Low Power Wake-up (LP-WUS) and synchronization signals on top of MR (Mobile Response) to reduce terminal power consumption while maintaining low latency. When the terminal performs mobility management, it needs to perform measurements on the received signals for the corresponding measurement purpose. The terminal can use different receivers to measure different received signals.

[0031] The measurement behavior of a terminal can affect the actual measurement results of the receiver and the terminal's power consumption. Currently, in scenarios where both MR and LR coexist in a terminal, unreasonable wireless measurement operations by the terminal can lead to problems such as mutual interference between receivers and excessive power consumption.

[0032] For example, if the MR and LR simultaneously monitor or measure pilot signals at the same or similar frequencies, mutual interference may occur, leading to inaccurate or invalid measurement results. As another example, while the LR is designed to save energy through low-power design, if the LR and MR perform similar tasks simultaneously, it may increase the overall power consumption of the terminal, negating the energy-saving effect of the LR.

[0033] Therefore, in this embodiment of the present disclosure, the first node can receive a first signaling from the second node. This first signaling is used to perform wireless measurement configuration on the first node. Subsequently, the first node can perform wireless measurement through a target receiver among multiple receivers based on the first signaling. In this way, the second node can configure the first node to perform wireless measurement through the target receiver via signaling, thereby reducing mutual interference between receivers.

[0034] In this disclosure, the mobile communication network includes, but is not limited to, wireless local area network (WiFi), third-generation mobile communication technology (3G), fourth-generation mobile communication technology (4G), fifth-generation mobile communication technology (5G), and future mobile communication networks. The network architecture of the mobile communication network may include at least a first communication node and a second communication node.

[0035] It should be understood that in this example, the first communication node can also be a terminal-side device (e.g., including but not limited to a terminal), and the second communication node can also be a network-side device (e.g., including but not limited to a base station). The first communication node and the second communication node can be referred to as the first node and the second node, respectively. Furthermore, the first node and the second node can also be modules of a device in a communication system, or protocol layers in a communication system. This module can be implemented as a software module, a hardware module, or a combination of software and hardware modules.

[0036] As exemplarily shown in FIG1, a communication system provided in an embodiment of the present disclosure includes a base station 101 and a terminal 102. There may be one or more base stations 101 and terminals 102, and the number is not limited.

[0037] Base station 101 is a device located on the access network side of the aforementioned communication system, possessing wireless transceiver capabilities, or a chip or chip system that can be installed on such device. Base station 101 includes, but is not limited to: access points (APs) in WiFi systems, such as home gateways, routers, servers, switches, bridges, etc.; evolved NodeBs (eNBs), radio network controllers (RNCs), NodeBs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home base stations (e.g., home evolved NodeBs, or home NodeBs, HNBs), base band units (BBUs), wireless relay nodes, wireless backhaul nodes (e.g., integrated access and backhaul (IAB) nodes), transmission and reception points (TRPs or transmission points, TPs), etc., and can also be 5G base stations, such as new radio (NR) stations. In a 5G radio (NR) system, a gNB, or a transmission point (TRP or TP), can be a gNB or a group of antenna panels (including multiple antenna panels) in a 5G system base station. Alternatively, it can be a network node constituting a gNB or transmission point, such as a baseband unit (BBU), a distributed unit (DU), a roadside unit (RSU) with base station functionality, NG radio access network (NG-RAN) equipment, or a 6G base station. Base station 101 also includes base stations in different networking modes, such as a master evolved NodeB (MeNB) and a secondary eNB (SeNB, or secondary gNB, SgNB). Base station 101 also includes different types, such as terrestrial base stations, airborne base stations, and satellite base stations.

[0038] Terminal 102 is a device with wireless communication capabilities that can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted. It can also be deployed on water (such as on ships) or in the air (e.g., on airplanes, balloons, and satellites). Terminal 102 is also known as user equipment (UE), mobile station (MS), mobile terminal (MT), and terminal equipment, and is a device that provides voice and / or data connectivity to users. For example, terminal 102 includes handheld devices and vehicle-mounted devices with wireless connectivity. Currently, terminal 102 can be: mobile phone, tablet computer, laptop computer, PDA, mobile internet device (MID), wearable device (e.g., smartwatch, smart bracelet, pedometer, etc.), in-vehicle device (e.g., car, bicycle, electric vehicle, airplane, ship, train, high-speed rail, etc.), virtual reality (VR) device, augmented reality (AR) device, wireless terminal in industrial control, smart home device (e.g., refrigerator, television, air conditioner, electricity meter, etc.), smart robot, workshop equipment, wireless terminal in self-driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, or wireless terminal in smart home, flying device (e.g., smart robot, hot air balloon, drone, airplane), etc. In one possible application scenario disclosed in this disclosure, the terminal is a terminal that frequently operates on the ground, such as in-vehicle device. In this disclosure, for ease of description, the chip deployed in the above-mentioned device, such as a system-on-a-chip (SOC), a baseband chip, or other chip with communication functions, may also be referred to as a terminal. For example, the terminal 102 in the embodiments of this disclosure may be a terminal with certain characteristics, such as a terminal with LP-WUS capability, a Rel-19 terminal, a 6G terminal, etc.

[0039] In some embodiments, terminal 102 may include multiple receivers, such as MR and LR. The signals received by terminal 102 based on different receivers may be inconsistent, and the measurement purposes of different signals may also differ.

[0040] For MR, the MR mainly receives the primary synchronization signal (PSS) / secondary synchronization signal (SSS) to perform synchronization and measurement operations.

[0041] For example, the MR can receive PSS / SSS signals. When the MR is enabled, the terminal 102 can perform a measurement and evaluation of the serving cell based on the synchronization signal-reference received power (SS-RSRP) and the synchronization signal-reference received quality (SS-RSRQ). If the measurement and evaluation determine that the current serving cell quality is good, the terminal 102 will continue to camp on the current serving cell. Conversely, if the measurement and evaluation determine that the current serving cell quality is poor, the terminal 102 will determine to perform neighbor cell measurement, cell handover, or cell reselection. In addition, when there are high-priority frequencies configured in the network, even if the current serving cell quality is good, the terminal 102 still needs to perform inter-frequency or inter-system neighbor cell measurement, measuring the high-priority frequency information at a certain period.

[0042] For LR, there are generally two types: LR based on on-off keying (OOK) signals (OOK-based LR) and LR based on orthogonal frequency division multiplexing (OFDM-based LR).

[0043] For example, the OOK-based LR is used to receive LP-WUS and low-power synchronization signal (LP-SS). When terminal 102 is configured with discontinuous reception (DRX) and there is no data service transmission, the MR enters a sleep state, waking up only during DRX ON to perform paging monitoring. Terminal 102 can monitor LP-WUS based on the LR while the MR is in deep sleep.

[0044] As shown in Figure 2, when a detection requirement exists (e.g., base station 101 needs to send a paging message to terminal 102), base station 101 can send an LP-WUS. Terminal 102 receives the LP-WUS via the LR and wakes up the MR. Then, terminal 102 detects the paging occasion (PO) via the MR to receive the paging message. When network access is required, base station 101 can wake up terminal 102's MR by sending an LP-WUS. After paging, the MR can monitor the signals on the physical downlink control channel (PDCCH) and the physical downlink shared channel (PDSCH) to perform random access (RA) operations. This method eliminates the need for continuous monitoring by the MR, thus reducing terminal power consumption.

[0045] For example, LP-SS is similar to PSS / SSS and is primarily used to perform wireless measurements. For instance, wireless measurements can be radio resource management (RRM) measurements, including layer 3 (L3) measurements. L3 is the radio resource control (RRC) layer in the communication system. LR can perform measurements of the serving cell based on the RSRP (LP-RSRP) and RSRQ (LP-RSRQ) of LP-SS and determine the quality of the current serving cell. Here, when LR is enabled, terminal 102 typically performs serving cell measurements through LR, but not measurements of neighboring cells.

[0046] For example, an OFDM-based LR is used to receive PSS / SSS and LP-SS. The main function of the OFDM-based PSS / SSS signal is the same as that of the MR PSS / SSS signal; the difference lies in the receiver used to receive the PSS / SSS. PSS / SSS is primarily used to perform measurements of the serving cell and neighboring cells based on SS-RSRP and SS-RSRQ. LP-SS is described above and will not be repeated here.

[0047] In some embodiments, the LR and MR can operate in the same frequency band or in different frequency bands. The MR can support L3 measurements on multiple frequency bands. However, the LR typically cannot have LP-WUR signal reception capability on all frequency bands supported by the MR of terminal 102. For example, as shown in FIG3, the MR supports 5 operating frequency bands and the LR supports 1 operating frequency band, where the current operating frequency band of the MR is different from the current operating frequency band of the LR.

[0048] When the operating frequency bands of MR and LR are the same, the channel conditions or channel changes of the frequency bands in which MR and LR are located are similar. At this time, the L3 measurement results of MR and LR are relatively different and can influence each other, satisfying the RRM measurement offloading condition, that is, the wireless measurement task can be offloaded to a receiver to perform wireless measurement.

[0049] When the operating frequency bands of MR and LR are different, there will be certain differences in the channel conditions or channel changes of the frequency bands in which MR and LR operate. In this case, it is difficult to determine the difference between the L3 measurement results of MR and LR, so the L3 measurement results of MR and LR may not affect each other.

[0050] In some embodiments, when the operating frequency bands of MR and LR are different, the channel conditions or channel changes corresponding to different frequency bands may be inconsistent. In this embodiment, the difference in RSRP measured by LR and MR can be determined based on the signal received power difference threshold, thereby assessing whether the L3 measurement results of the two receivers can affect each other.

[0051] If the difference in signal received power measured by the two receivers by terminal 102 is within the range of the signal received power difference threshold, it indicates that the difference in L3 measurement results between MR and LR is small, and therefore RRM measurement offloading can be performed. If the difference in signal received power measured by the two receivers by terminal 102 is not within the range of the signal received power difference threshold, it indicates that the difference in L3 measurement results between MR and LR is large, and therefore RRM measurement offloading cannot be performed.

[0052] For example, the signal received power difference threshold can be defined as RSRPchangeforLRandMR.

[0053] In some embodiments, LR and MR can both have serving cell measurement capabilities, and MR can have neighboring cell measurement capabilities.

[0054] In other embodiments, both LR and MR may have the ability to measure the serving cell and neighboring cells, thereby enhancing the flexibility and reliability of the communication system.

[0055] However, the reception of different signals by different receivers and the coexistence of different receivers can affect the terminal's measurement behavior and power-saving effect. Therefore, embodiments of this disclosure provide a wireless measurement method that defines the wireless measurement process and terminal measurement behavior, thereby optimizing load balancing, ensuring system performance, and improving user experience while ensuring power saving.

[0056] It should be noted that the various embodiments of this disclosure can be referenced or learned from each other. For example, the same or similar steps, method embodiments, system embodiments and device embodiments can be referenced from each other without limitation.

[0057] The wireless measurement method provided in this disclosure will be described below with reference to the communication system shown in Figure 1, taking the interaction between the first node and the second node as an example. It should be noted that in the following embodiments of this disclosure, the first node and the second node can be devices, modules of the devices, or protocol layers in the communication system. For example, the first node can be terminal 102, and the corresponding second node can be base station 101. This disclosure uses the first node and the second node as examples of the execution subjects in this interaction illustration, but this disclosure does not limit the execution subjects of the interaction illustration.

[0058] Figure 4 is a flowchart of a wireless measurement method provided in an embodiment of this disclosure. As shown in Figure 4, the method includes the following steps:

[0059] Step 401: Receive the first signaling from the second node.

[0060] Here, the first signaling is used to perform wireless measurement configuration on the first node.

[0061] For example, the wireless measurement configuration can be the configuration of the receiver used by the first node to perform wireless measurements, or the configuration of parameters involved when the first node performs wireless measurements. For example, the parameters involved can be decision parameters for triggering wireless measurements, resource parameters used to perform wireless measurements, etc.

[0062] In some embodiments, the first signaling is carried in at least one of the following: system information block 1 (SIB1), RRC message, medium access control control element (MAC CE), or downlink control information (DCI).

[0063] For example, the first signaling can configure parameters for wireless measurements dynamically, statically, or semi-statically. For instance, in the case of dynamic configuration, the wireless measurement configuration of the first signaling can apply to the terminal's next wireless measurement; that is, the first signaling is effective before the terminal performs an L3 measurement. In the case of static configuration, the wireless measurement configuration of the first signaling can apply to multiple subsequent wireless measurements by the terminal.

[0064] Step 402: Based on the first signaling, perform wireless measurement through the target receiver among multiple receivers.

[0065] For example, the first node may include multiple receivers. These could include a master receiver and a low-power wake-up receiver. Taking multiple receivers including a master receiver and a low-power wake-up receiver as an example, the first node may perform wireless measurements based on a first signaling signal via the master receiver, or it may perform wireless measurements based on the first signaling signal via the low-power wake-up receiver.

[0066] In some embodiments, after performing wireless measurements via the target receiver, the first node may report the measurement results to the second node. The reporting method may vary depending on the terminal implementation, and this disclosure does not limit it.

[0067] Based on the above technical solution, in this embodiment of the present disclosure, the first node can receive a first signaling from the second node. This first signaling is used to configure the receiver of the first node for wireless measurement. Subsequently, the first node can perform wireless measurement through a target receiver among multiple receivers based on the first signaling. In this way, the second node can configure the first node to perform wireless measurement through the target receiver by means of signaling, thereby reducing mutual interference between receivers.

[0068] The following describes the scheme in which the first signaling performs wireless measurement configuration on the first node in the embodiments of this disclosure. The second node can configure the relevant parameters and behaviors of the wireless measurement of the first node through the first signaling, thereby achieving load balancing, optimizing resource allocation, and improving system performance and user experience.

[0069] As one embodiment provided in this disclosure, the first signaling includes first indication information, which is used to indicate a target receiver for wireless measurement and / or to indicate a channel condition judgment threshold.

[0070] Here, the channel condition judgment threshold is used to determine the channel conditions between the first node and the second node. Thus, in this embodiment of the disclosure, the second node can directly or indirectly instruct the first node on the target receiver for wireless measurement, thereby avoiding mutual interference between receivers during wireless measurement.

[0071] In some embodiments, the first indication information is used to indicate at least one of the following:

[0072] 1-1. Perform wireless measurements using the master receiver among multiple receivers;

[0073] 1-2. Perform wireless measurements by low-power wake-up of the receiver among multiple receivers;

[0074] 1-3. Channel condition judgment threshold.

[0075] For example, the first indication information may include at least one sub-information that indicates the aforementioned information. For instance, the first indication information may be an x-bit field, where x is greater than or equal to 1, and each bit in the x bits may indicate one of the aforementioned pieces of information.

[0076] Taking a 2-bit field as an example, the first bit can indicate the receiver used to perform the wireless measurement. For instance, when the first bit is 0, it indicates that the wireless measurement is performed by the master receiver among multiple receivers. When the first bit is 1, it indicates that the wireless measurement is performed by a low-power wake-up receiver among multiple receivers. Alternatively, when the first bit is 0, it indicates that the wireless measurement is performed by a low-power wake-up receiver among multiple receivers. When the first bit is 1, it indicates that the wireless measurement is performed by the master receiver among multiple receivers.

[0077] The second bit can directly or indirectly indicate the channel condition judgment threshold. For example, the value of the bit can correspond to the channel condition judgment threshold. When the second bit is 0, it can indicate that the channel condition judgment threshold is the first value. When the second bit is 1, it can indicate that the channel condition judgment threshold is the second value.

[0078] In some embodiments, the operating frequency bands of the master receiver and the low-power wake-up receiver may be the same or different. For example, the master receiver may operate in a high-frequency band, while the low-power wake-up receiver may operate in a low-frequency band. The operating frequency bands of the master receiver and the low-power wake-up receiver may or may not have high-priority frequency points configured.

[0079] For example, the channel conditions between the first node and the second node can be determined by multiple dimensions, such as by the signal received power (e.g., RSRP) / signal quality (e.g., RSRQ) on the channel, or by the channel state information on the channel.

[0080] As an embodiment provided in this disclosure, and in conjunction with the embodiment shown in FIG4, as shown in FIG5, when the first indication information is used to indicate the channel condition judgment threshold, the above step 402 can be implemented by the following steps:

[0081] Step 501: Determine the channel conditions between the first node and the second node based on the channel condition judgment threshold.

[0082] Here, the threshold for judging channel conditions can be an absolute value or a relative value.

[0083] In some embodiments, the first node can acquire multiple measurement results obtained within a preset time window. If the difference between the maximum and minimum measurement results among the multiple measurement results is less than or equal to a channel condition judgment threshold, the first node determines that the channel condition is slow channel change or stable channel state. If the difference between the maximum and minimum measurement results among the multiple measurement results is greater than the channel condition judgment threshold, the first node determines that the channel condition is rapid channel change or unstable channel state.

[0084] For example, the measurement result can be based on the pilot signal. In this case, the channel condition judgment threshold can be an absolute value, such as y dB. With a preset time window T, the first node measures multiple results (e.g., RSRP, RSRQ, etc.) within T. If the difference between the maximum and minimum measurement results is greater than the channel condition judgment threshold y, it indicates that the current channel state fluctuates significantly, i.e., the channel changes rapidly or the channel state is unstable. Conversely, if the difference between the maximum and minimum measurement results is less than or equal to the channel condition judgment threshold y, it indicates that the current channel state fluctuates less, i.e., the channel changes slowly or the channel state is stable.

[0085] In other embodiments, the first node can acquire multiple measurement results obtained within a preset time window and determine the average measurement result based on the multiple measurement results.

[0086] If the change in the current measurement result compared to the average measurement result is less than or equal to the channel condition judgment threshold, the first node determines the channel condition as either slow channel change or stable channel state.

[0087] If the change in the current measurement result compared to the average measurement result is greater than the channel condition judgment threshold, the first node determines that the channel condition is either rapidly changing or unstable.

[0088] For example, the channel condition judgment threshold can be a relative value, such as 10%. Using a preset time window T, the first node measures multiple results (e.g., RSRP, RSRQ, etc.) within T and calculates the average measurement result. The change in the current measurement result relative to the average measurement result can be represented by the ratio obtained by subtracting the average measurement result from the current measurement result, and then dividing that difference by the average measurement result. If the change is greater than the channel condition judgment threshold of 10%, it indicates that the current channel state fluctuates significantly, meaning the channel changes rapidly or the channel state is unstable. If the change is less than or equal to the channel condition judgment threshold of 10%, it indicates that the current channel state fluctuates less, meaning the channel changes slowly or the channel state is stable.

[0089] Step 502: Determine the target receiver from multiple receivers based on channel conditions and perform wireless measurements.

[0090] In some embodiments, when the channel conditions are characterized by rapid channel changes or unstable channel states, the master receiver among multiple receivers is used as the target receiver to perform wireless measurements. For example, if the master receiver is in sleep mode, the terminal can wake up the master receiver in response to the first indication information to perform wireless measurements.

[0091] When the channel conditions are slow or the channel state is stable, the low-power wake-up receiver among multiple receivers is used as the target receiver to perform wireless measurements.

[0092] It should be understood that in the embodiments of this disclosure, the target receiver for wireless measurement can be indirectly indicated through channel conditions. When the channel conditions between the first node and the second node are characterized by rapid channel changes or unstable channel states, the complexity of wireless measurement is high. Therefore, wireless measurement can be performed by the master receiver to ensure measurement accuracy. When the channel conditions between the first node and the second node are characterized by slow channel changes or stable channel states, the complexity of wireless measurement is low. Therefore, wireless measurement can be performed by low-power wake-up of the receiver to reduce power consumption.

[0093] As one embodiment provided in this disclosure, the first node can also report the measurement behavior of the first node to the second node. Referring to the embodiment shown in Figure 5, and as shown in Figure 6, the method further includes the following steps:

[0094] Step 601: Send the second signaling to the second node.

[0095] Here, the second signaling includes auxiliary information, which is used to instruct the first node on the target receiver used to perform wireless measurements.

[0096] For example, the assistance information can be UE assistance information (UAI).

[0097] In some embodiments, the second signaling is carried on uplink control information.

[0098] For example, the first node can send a UAI to the second node to indicate which receiver to use for the measurement under the current channel conditions.

[0099] As one embodiment provided in this disclosure, the first signaling includes terminal capability information. The terminal capability information is used to configure the terminal capabilities of the first node to perform wireless measurements using either a master receiver or a low-power wake-up receiver.

[0100] For example, the first signaling can be UE capability signaling, and the terminal capability information can be UseLRMeas and UseMRMeas. UseLRMeas indicates the terminal capability configured to perform wireless measurements using a low-power wake-up receiver, and UseMRMeas indicates the terminal capability configured to perform wireless measurements using a master receiver. These terminal capabilities can be optional, thus allowing the second node to determine the first node's wireless measurement behavior through terminal capability configuration.

[0101] As one embodiment provided in this disclosure, the first signaling includes second indication information, which is used to indicate the time-domain resources and / or frequency-domain resources used by the first node to perform wireless measurement through the target receiver.

[0102] In some embodiments, the time-domain resource is a time window. The time window can be configured periodically or aperiodically.

[0103] When the time window is configured non-periodicly, the opening time and duration of the time window are determined based on at least one of the following: the network load currently being monitored in real time, signal interference, and measurement requirements. This allows for dynamic adjustment of the start time and duration of time-domain resources.

[0104] Taking time-domain resources as an example, these resources can be time windows. Within the time window indicated by the second indication information, the first node can perform wireless measurements through the target receiver. For example, the second indication information can be TimingforL3Meas.

[0105] In some embodiments, the frequency domain resource can be a frequency band or a resource block (RB). For example, the first node can perform wireless measurements using the frequency domain resource indicated by the second indication information via a target receiver. Exemplarily, the second indication information can be PreConfigFreqForMRandLR.

[0106] In some embodiments, the measurement behavior of a first receiver among a plurality of receivers on the time-domain and / or frequency-domain resources indicated by the second indication information is configured to have low priority. The first receiver operates in the same frequency band as the target receiver, or the channel difference between their operating frequency bands is less than or equal to a channel difference threshold. That is, the first node preferentially performs wireless measurements using the time-frequency resources indicated by the second indication information through the target receiver, while suspending operations on those time-frequency resources by other receivers operating in the same or similar frequency bands as the target receiver. This resource isolation method can further reduce potential interference between different receivers.

[0107] For example, both the master receiver and the low-power wake-up receiver of the first node are turned on, and the two receivers operate in the same frequency band or the channel difference between their operating frequency bands is less than or equal to a channel difference threshold. When wireless measurement needs to be performed, the first node can configure a time window for the target receiver (e.g., the master receiver) through a second indication information from the second node, and perform wireless measurement operations within that time window. At the same time, it can suspend the wireless measurement operations performed by the low-power wake-up receiver within that time window, thereby reducing potential interference between the master receiver and the low-power wake-up receiver.

[0108] In some embodiments, the second indication information may also indicate the time-domain and / or frequency-domain resources used by other receivers among a plurality of receivers to perform wireless measurements.

[0109] Taking frequency domain resources as an example, both the master receiver and the low-power wake-up receiver of the first node are in the powered-on state, and the two receivers operate in the same frequency band or the channel difference between their operating frequency bands is less than or equal to the channel difference threshold. When wireless measurement needs to be performed, the first node can pre-instruct the reserved target receiver (e.g., the master receiver) and the low-power wake-up receiver to use the second indication information from the second node to reserve independent frequency bands or resource blocks. This allows the first node to perform wireless measurement on different allocated frequency bands or resource blocks using the master receiver and the low-power wake-up receiver respectively, thereby further reducing potential interference between the master receiver and the low-power wake-up receiver based on the isolation of frequency domain resources.

[0110] As one embodiment provided in this disclosure, the first signaling includes third indication information, which is used to instruct the first node to adjust the transmit power of the receiver and / or to indicate a channel condition judgment threshold. The channel condition judgment threshold is used to determine the channel conditions between the first node and the second node. Thus, in this embodiment of the disclosure, the second node can directly or indirectly instruct the first node to adjust the transmit power of the receiver, thereby further reducing mutual interference between receivers during wireless measurement.

[0111] In some embodiments, the third indication information is used to indicate at least one of the following:

[0112] 2-1. Reduce the transmit power of the low-power wake-up receiver in a multi-receiver configuration;

[0113] 2-2. Reduce the transmit power of the main receiver among multiple receivers;

[0114] 2-3. Channel condition judgment threshold.

[0115] For example, the third indication information may include at least one sub-information that indicates the aforementioned information. For instance, the third indication information may be an x-bit field, where x is greater than or equal to 1, and each bit in the x bits may indicate one of the aforementioned pieces of information.

[0116] Taking a 2-bit field as an example, the first bit can instruct the first node to adjust the transmitter power of the receiver. For instance, when the first bit is 0, it can instruct to reduce the transmitter power of the low-power wake-up receiver among multiple receivers. When the first bit is 1, it can instruct to reduce the transmitter power of the master receiver among multiple receivers. Alternatively, when the first bit is 0, it can instruct to reduce the transmitter power of the master receiver among multiple receivers. When the first bit is 1, it can instruct to reduce the transmitter power of the low-power wake-up receiver among multiple receivers.

[0117] The second bit can directly or indirectly indicate the channel condition judgment threshold. For example, the value of the bit can correspond to the channel condition judgment threshold. When the second bit is 0, it can indicate that the channel condition judgment threshold is the first value. When the second bit is 1, it can indicate that the channel condition judgment threshold is the second value.

[0118] In some embodiments, the operating frequency bands of the master receiver and the low-power wake-up receiver may be the same or different. For example, the master receiver may operate in a high-frequency band, while the low-power wake-up receiver may operate in a low-frequency band. The operating frequency bands of the master receiver and the low-power wake-up receiver may or may not have high-priority frequency points configured.

[0119] For example, the channel conditions between the first node and the second node can be determined by multiple dimensions, such as by the signal received power (e.g., RSRP) / signal quality (e.g., RSRQ) on the channel, or by the channel state information on the channel.

[0120] As one embodiment provided in this disclosure, and in conjunction with the embodiment shown in FIG4, as shown in FIG7, when the third indication information is used to indicate the channel condition judgment threshold, the method further includes the following steps:

[0121] Step 701: Determine the channel conditions between the first node and the second node based on the channel condition judgment threshold.

[0122] Here, the threshold for judging channel conditions can be an absolute value or a relative value.

[0123] In some embodiments, the first node can acquire multiple measurement results obtained within a preset time window. If the difference between the maximum and minimum measurement results among the multiple measurement results is less than or equal to a channel condition judgment threshold, the first node determines that the channel condition is slow channel change or stable channel state. If the difference between the maximum and minimum measurement results among the multiple measurement results is greater than the channel condition judgment threshold, the first node determines that the channel condition is rapid channel change or unstable channel state.

[0124] In other embodiments, the first node can acquire multiple measurement results obtained within a preset time window and determine the average measurement result based on the multiple measurement results.

[0125] If the change in the current measurement result compared to the average measurement result is less than or equal to the channel condition judgment threshold, the first node determines the channel condition as slow channel change or stable channel state. If the change in the current measurement result compared to the average measurement result is greater than the channel condition judgment threshold, the first node determines the channel condition as fast channel change or unstable channel state.

[0126] For related information, please refer to step 501 above; it will not be repeated here.

[0127] Step 702: Adjust the receiver's transmit power based on channel conditions.

[0128] In some embodiments, when channel conditions are characterized by rapid channel changes or unstable channel states, the first node can reduce the transmit power of the low-power wake-up receiver among multiple receivers. In this case, the first node can perform wireless measurements through the master receiver, and reducing the transmit power of the low-power wake-up receiver can reduce interference to the master receiver.

[0129] When channel conditions are characterized by slow channel changes or stable channel states, the first node can reduce the transmit power of the master receiver among multiple receivers. In this case, the first node performs wireless measurements by using a low-power wake-up receiver, and reducing the transmit power of the master receiver can reduce interference to the low-power wake-up receiver.

[0130] It should be understood that in the embodiments of this disclosure, channel conditions can be used to indirectly indicate how to adjust the transmitter power of the receiver. When the channel conditions between the first node and the second node are characterized by rapid channel changes or unstable channel states, the complexity of wireless measurement is higher, making it more suitable for the master receiver to perform wireless measurements. Therefore, the transmitter power of other receivers, such as low-power wake-up receivers, can be reduced at this time to reduce interference to the master receiver. When the channel conditions between the first node and the second node are characterized by slow channel changes or stable channel states, the complexity of wireless measurement is lower, making it more suitable for low-power wake-up receivers to perform wireless measurements. Therefore, the transmitter power of other receivers, such as the master receiver, can be reduced at this time.

[0131] Furthermore, in this embodiment of the present disclosure, the first signaling can be used to indicate the determination parameters of the RRM measurement offload condition, so that the first node can determine whether the RRM measurement offload can be triggered based on the current channel conditions, thereby further reducing power consumption.

[0132] As one embodiment provided in this disclosure, the first signaling includes fourth indication information, which is used to indicate a threshold for the difference in signal received power among a plurality of receivers.

[0133] In some embodiments, the multiple receivers include a master receiver and a low-power wake-up receiver, which operate in different frequency bands. Referring to the embodiment shown in Figure 4, and as shown in Figure 8, step 402 above can be implemented through the following steps:

[0134] Step 801: If the difference in signal received power measured between the main receiver and the low-power wake-up receiver is less than or equal to the signal received power difference threshold, perform wireless measurement using the main receiver or the low-power wake-up receiver as the target receiver.

[0135] For example, the first node can determine the corresponding RSRP through the main receiver and the low-power wake-up receiver respectively, thereby obtaining the difference value of the RSRP of the two receivers. If the difference value is less than or equal to the signal received power difference threshold, it indicates that the channel conditions or channel changes in the frequency bands of the main receiver and the low-power wake-up receiver are relatively similar. At this time, the measurement results of the main receiver and the low-power wake-up receiver can affect each other. Therefore, the first node can trigger wireless measurement offloading, that is, perform wireless measurement with the main receiver or the low-power wake-up receiver as the target receiver. The above wireless measurement offloading can be fully offloading or partially offloading, and this disclosure does not limit it in this way.

[0136] For example, the first node can be divided into multiple states, or multiple scenarios, based on the operating conditions of different receivers. The first node can select which receiver to offload the wireless measurement task to for execution based on the reselection or switching of different states.

[0137] In some embodiments, the state of the first node is any one of the first state, the second state, and the third state.

[0138] Here, in the first state, the first node is used to perform wireless measurements via a low-power wake-up receiver. In the second state, the first node is used to perform wireless measurements via a master receiver and a low-power wake-up receiver. In the third state, the first node is used to perform wireless measurements via the master receiver.

[0139] For example, as shown in Figure 9, different states of the first node can correspond to different coverage areas. The first state corresponds to area 1 (fully LR area), at which time the main receiver is off, the low-power wake-up receiver is on, and wireless measurement is independently completed by the first node through the low-power wake-up receiver.

[0140] The second state corresponds to region 2 (MR+LR region). At this time, both the main receiver and the low-power wake-up receiver are turned on. Wireless measurement is then completed by the first node through the main receiver and the low-power wake-up receiver.

[0141] The third state corresponds to region 2 (fully MR region). At this time, the main receiver is in the powered-on state. Whether the low-power wake-up receiver is powered on depends on the terminal implementation. At this time, the wireless measurement is completed independently by the first node through the main receiver.

[0142] In some embodiments, when the first node is reselected from the first state or switched to the second state, the first node offloads the wireless measurement task to the main receiver to perform the wireless measurement.

[0143] For example, the RRC states of the first node include disconnected states, such as idle and inactive states, and connected states. When the RRC state of the first node is disconnected, the first node reselects from the first state to the second state. When the RRC state of the first node is connected, the first node switches from the first state to the second state.

[0144] For example, each state of the first node can have an entry threshold and an exit threshold. When the first node is in the first state, it can wake up the receiver with low power to measure the corresponding RSRP. If the measured RSRP is less than or equal to the exit threshold of the first state, the first node can reselect from the first state or switch to the second state. At this time, the first node can wake up the master receiver and measure the corresponding RSRP through the master receiver. If the difference between the RSRPs of the two receivers is less than or equal to the signal received power difference threshold, the first node can offload the wireless measurement task to the master receiver.

[0145] In other embodiments, when the first node is reselected from the first state or switched to the third state, the first node offloads the wireless measurement task to the main receiver to perform the wireless measurement.

[0146] For example, when the first node is in the first state, it can wake up the receiver with low power to measure the corresponding RSRP. If the measured RSRP is less than or equal to the exit threshold of the first state, the first node can reselect from the first state or switch to the third state. At this time, the first node can wake up the master receiver and measure the corresponding RSRP through the master receiver. If the difference between the RSRPs of the two receivers is less than or equal to the signal received power difference threshold, the first node can offload the wireless measurement task to the master receiver.

[0147] In some other embodiments, when the first node is reselected from the third state or switched to the first state, the first node offloads the wireless measurement task to the low-power wake-up receiver to perform the wireless measurement.

[0148] For example, when the first node is in the third state, it can measure the corresponding RSRP through the main receiver. If the measured RSRP is greater than the entry threshold for the first state, the first node can reselect from the third state or switch back to the first state. At this time, the first node can wake up the low-power wake-up receiver and measure the corresponding RSRP through it. If the difference in RSRP between the two receivers is less than or equal to the signal received power difference threshold, the first node can offload the wireless measurement task to the low-power wake-up receiver.

[0149] In some other embodiments, when the first node is reselected from the third state or switches to the second state, the first node offloads the wireless measurement task to the low-power wake-up receiver to perform the wireless measurement.

[0150] For example, when the first node is in the third state, it can measure the corresponding RSRP through the main receiver. If the measured RSRP is greater than the entry threshold for the second state, the first node can reselect from the third state or switch back to the second state. At this time, the first node can wake up the low-power wake-up receiver and measure the corresponding RSRP through the low-power wake-up receiver. If the difference in RSRP between the two receivers is less than or equal to the signal received power difference threshold, the first node can offload the wireless measurement task to the low-power wake-up receiver.

[0151] In some other embodiments, when the first node is reselected from the second state or switches to the first state, the first node offloads the wireless measurement task to the low-power wake-up receiver to perform the wireless measurement.

[0152] In some embodiments, when the first node is in the second state, since both the master receiver and the low-power wake-up receiver are in the on state, the first node can determine whether the entry threshold of the first state is met by measuring the RSRP of the master receiver and / or the low-power receiver.

[0153] Taking the RSRP measured by the main receiver as an example, when the first node is in the second state, it can measure the corresponding RSRP through the main receiver. If the measured RSRP is greater than the entry threshold for the first state, the first node can reselect from the second state or switch back to the first state. At this time, the first node can measure the corresponding RSRP through the low-power wake-up receiver. If the difference between the RSRPs of the two receivers is less than or equal to the signal received power difference threshold, the first node can offload the wireless measurement task to the low-power wake-up receiver.

[0154] Taking the RSRP measured by the main receiver and the low-power wake-up receiver as an example, when the first node is in the second state, it can measure the corresponding RSRP using both the main receiver and the low-power wake-up receiver. If both measured RSRPs are greater than the corresponding entry threshold for the first state, the first node can reselect from the second state or switch back to the first state. In this case, if the difference between the RSRPs of the two receivers is less than or equal to the signal received power difference threshold, the first node can offload the wireless measurement task to the low-power wake-up receiver. If at least one of the measured RSRPs is less than or equal to the corresponding entry threshold for the first state, then wireless measurement offloading cannot be triggered.

[0155] In some other embodiments, when the first node is reselected from the second state or switches to the third state, the first node offloads the wireless measurement task to the main receiver to perform the wireless measurement.

[0156] In some embodiments, when the first node is in the second state, since both the master receiver and the low-power wake-up receiver are in the on state, the first node can determine whether the exit threshold of the second state is met by measuring the RSRP of the master receiver and / or the low-power receiver.

[0157] Taking the RSRP measured by the main receiver as an example, when the first node is in the second state, it can measure the corresponding RSRP through the main receiver. If the measured RSRP is less than or equal to the exit threshold of the second state, the first node can reselect from the second state or switch to the third state. At this time, the first node can use low-power wake-up to measure the corresponding RSRP. If the difference between the RSRPs of the two receivers is less than or equal to the signal received power difference threshold, the first node can offload the wireless measurement task to the main receiver.

[0158] Taking the RSRP measured by the main receiver and the low-power wake-up receiver as an example, when the first node is in the second state, it can measure the corresponding RSRP using both the main receiver and the low-power wake-up receiver. If the two measured RSRPs are both less than or equal to the exit threshold of the corresponding second state, the first node can reselect from the second state or switch back to the first state. At this time, if the difference between the RSRPs of the two receivers is less than or equal to the signal received power difference threshold, the first node can offload the wireless measurement task to the main receiver. If at least one of the two measured RSRPs is greater than the exit threshold of the corresponding second state, then wireless measurement offloading cannot be triggered.

[0159] Based on the above technical solution, in this embodiment of the present disclosure, the first node can select to offload the wireless measurement task to a suitable receiver to perform wireless measurement according to different state switching scenarios, so as to adapt to the current channel conditions of the first node and enhance the flexibility and reliability of the communication system.
