[0044] For ease of understanding, some relevant technical knowledge involved in the embodiments of the present application is first introduced. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0045] With the development of mobile communication technology, the application areas of the Internet of Things are gradually expanding. However, without the support of external power supply, 5G IoT devices are difficult to implement in practice. This is because 5G devices in cellular networks consume tens of milliwatts of power even if they are not transmitting or receiving any data. This idle power consumption is due to the fact that 5G devices must perform regular measurements and check for potential paging messages.

[0046] In order to reduce the power consumption of the terminal device, the NR system introduces a low-power wake-up module and LP-WUS. The low-power wake-up module is also called a low-power wake-up receiver (LP-WUR) or a low-power wake-up radio (LP-WUR). The receiver can also be called a receiver. Exemplarily, when the terminal device is idle, the main communication module / receiver can be turned off or set to a deep sleep state, and the LP-WUS is only monitored through the LP-WUR, thereby achieving the purpose of reducing the power consumption of the terminal device. The main communication module / receiver of the terminal device can also be called the main radio (MR), and correspondingly, the low-power wake-up module can also be referred to as LR. When the MR is awakened, the terminal device can enter the radio resource control (RRC) connection state. The LP-WUR of the terminal device can be turned on continuously to receive the LP-WUS. Therefore, the LP-WUR can be independent of the 5G device, that is, the 5G device can be in a closed state when the LP-WUR is active and searching for potential LP-WUS. In order to ensure the low power consumption performance of terminal equipment, LP-WUS needs to be embedded in relevant communication systems (e.g., NR systems).

[0047] In some embodiments, LP-WUS can support a bandwidth of 5MHz-20MHz. When LP-WUS is embedded in a related communication system, the main communication module (or MR) and the low power wake-up module (LP-WUR or LR) on the terminal device side can be two modules or integrated into one module. Among them, LP-WUR can support multiple receiver architectures. Figures 2 to 4 Taking the three receiver architectures in as examples, LP-WUR is illustrated.

[0048] Figure 2 It is a schematic structural diagram of a LP-WUR based on radio frequency (RF) envelope detection. Figure 2The receiver architecture shown includes a matching network 201, an RF bandpass filter (BPF) 202, an RF low noise amplifier (LNA) 203, an RF envelope detector 204, a baseband (BB) asymmetric processing (AMP) 205, a BB low pass filter (LPF) 206, a 1-bit or multi-bit analog-to-digital converter (ADC) 207 and a digital BB processing 208.

[0049] exist Figure 2 In the architecture shown, the RF signal is directly converted to a baseband signal through an RF envelope detector. Since there is no local oscillator (LO) and phase-locked loop (PLL), relatively low power consumption can be achieved. Optionally, the architecture may include a 1-bit or multi-bit ADC, an RF LNA and / or a BB AMP, a high-Q matching network and / or an RF BPF and / or a BB LPF. Optionally, in order to support multiple frequency bands and / or carriers, multiple high-Q matching networks and / or RF BPFs or multiple off-chip components may be required to suppress adjacent channel interference or interference from traditional NR signals and / or other LP-WUS on adjacent subcarriers, and support frequency band and / or carrier tuning.

[0050] Figure 3 A schematic structural diagram of a LP-WUR based on a heterodyne architecture with intermediate frequency (IF) envelope detection is shown. Figure 3 The receiver architecture shown includes a matching network 301 , an RF BPF 302 , an RF LNA 303 , a mixer 304 , an LO 305 , an IF AMP 306 , an IF BPF 307 , an IF envelope detector 308 , a BB AMP 309 , a BB LPF 310 , a 1-bit or multi-bit ADC 311 , and a digital BB processing 312 .

[0051] exist Figure 3In the architecture shown, the RF signal is passed through an RF mixer with an LO to convert it to an intermediate frequency (IF) signal. The IF signal is converted to a baseband signal by IF envelope detection. Depending on the design, there may be one or more intermediate frequency stages to achieve lower power consumption by relaxing the accuracy and stability requirements of the LO. The architecture can apply a 1-bit or multi-bit ADC. High-Q matching networks and / or RF BPFs and / or IF BPFs (and / or BB LPFs) can be used to suppress adjacent channel interference or interference from traditional NR signals and / or other LP-WUS on adjacent subcarriers. Optionally, the architecture can apply some components to improve sensitivity, such as RFLNAs and / or IF AMPs and / or BB AMPs. Optionally, the architecture can achieve band and / or carrier tuning by tuning the LO frequency.

[0052] Figure 4 A schematic structural diagram of a LP-WUR based on a homodyne or zero-IF architecture with baseband (BB) envelope detection is shown. Figure 4 The receiver architecture shown includes a matching network 401 , an RF BPF 402 , an RF LNA 403 , a mixer 404 , an LO 405 , a BB AMP 406 , a BB LPF / BPF 407 , a 1-bit or multi-bit ADC 408 , and a digital BB processing 409 .

[0053] exist Figure 4 In the architecture shown, band and / or carrier tuning can be achieved by tuning the LO frequency. Using a BBBPF / LPF instead of a high-Q matching network and / or RF BPF can more effectively and simply suppress adjacent channel interference or interference from traditional NR signals and / or other LP-WUS on adjacent subcarriers. RF LNA can be applied to improve sensitivity. Baseband envelope detection (not shown in the figure) can be done in the analog domain (before ADC) or in the digital domain (after ADC).

[0054] According to the design architecture of LP-WUR, LP-WUS can be deployed only in some frequency bands / carriers. For terminal devices, deploying LP-WUS only in certain frequency bands / carriers can help reduce the cost of LP-WUR. Due to the limited dynamic range of terminal devices, different RF modules may be required to support different frequency bands (such as Figures 2 to 4 Limited frequency bands can reduce costs. For the network side, deploying LP-WUS only in certain frequency bands / carriers helps reduce system overhead. Therefore, it is attractive to allow the number of frequency bands / carriers supported by LP-WUR to be smaller than the number of frequency bands / carriers supported by MR.

[0055] In some embodiments, for a terminal device in idle / inactive mode, the cell reselection of the terminal device is not controlled by a network device (e.g., gNB), and therefore, the terminal device can freely select the frequency band / carrier to reside in.

[0056] Combination of the above Figures 2 to 4 A variety of LP-WUR architectures are introduced. All LP-WUR architectures can be applied to on-off keying (OOK) modulation. Some architectures can also be applied to other modulations, such as frequency-shift keying (FSK).

[0057] OOK is a well-known modulation scheme. OOK can allow low-power receiver implementations, i.e., envelope / energy detection. OOK is a special case of amplitude shift keying (ASK). OOK has only two amplitudes, ON and OFF. When applied to multi-carrier (MC) systems such as orthogonal frequency division multiplexing (OFDM), OOK is also called multi-carrier OOK because the ON and OFF signals usually span multiple subcarriers.

[0058] In some embodiments, in an OFDM-based MC-OOK system, a network node may perform waveform generation of multi-carrier amplitude shift keying (MC-ASK) using coded bits to generate a low power wake-up signal (LP-WUS).

[0059] The above introduces a variety of LP-WUR architectures and LP-WUS generation methods. For terminal devices, the activation / deactivation procedure of the entry / exit conditions of wake-up signal monitoring is the standard for the terminal device to decide whether to monitor LP-WUS in the cell. If the entry / exit conditions are met, the terminal device can activate / deactivate LP-WUS monitoring. However, how to determine the entry / exit conditions of wake-up signal monitoring and how the terminal device monitors LP-WUS are issues that need to be resolved.

[0060] On the one hand, the terminal device cannot expect to always be able to receive LP-WUS in the cell. For example, the serving cell that the terminal device is currently or about to enter may not support the LP-WUS mechanism. For another example, even if LP-WUS is sent in the serving cell, the terminal device may not be able to receive LP-WUS or successfully receive related reference signals due to being at the edge of the cell or the limited coverage of LP-WUS.

[0061] On the other hand, the terminal device measures the cell quality through the primary radio (MR) measurement based on the synchronization signal block (SSB) or the synchronization signal / physical broadcast channel block (SSB). However, the measurement results based on SSB may not fully guarantee the good coverage of the LP-WUS sent by the network device. Because the compensation offset between the primary synchronization signal (PSS) / secondary synchronization signal (SSS) and LP-WUS may be uncertain, it may cause the terminal device to repeatedly activate and deactivate the LP-WUS monitoring ping-pong situation.

[0062] Based on this, an embodiment of the present application proposes a method for wireless communication. Through this method, a terminal device (e.g., UE) can determine whether to enter / exit wake-up signal monitoring based on a measurement result indicating the transmission quality of the wake-up signal, thereby improving the communication effect when the terminal device monitors a low-power wake-up signal for energy saving.

[0063] For ease of understanding, the following Figure 5 The method proposed in the embodiment of the present application is described in detail. Figure 5 The method shown is executed by a terminal device.

[0064] The terminal device is any communication terminal that can receive the wake-up signal, and is not limited here. In some embodiments, the terminal device can be in an idle state or an inactive state. For example, the terminal device can be a UE in RRC idle (RRC_IDLE) / RRC inactive (RRC_INACTIVE) mode. In some embodiments, the terminal device can be in a connected state (CONNECTED).

[0065] In some embodiments, the terminal device is a communication terminal in the Internet of Things. The service cell where the terminal device is located can be an NTN cell or a terrestrial network (TN) cell.

[0066] The terminal device may include a first communication module and a second communication module. Exemplarily, the terminal device may include two independent communication modules to save power consumption. The first communication module is independent of the second communication module and may also be considered to be independent of the terminal device. Exemplarily, the first communication module and the second communication module in the terminal device may be integrated together, but the operating state and / or shutdown state of the two communication modules may be set separately.

[0067] As an example, the first communication module and the second communication module may be in different states respectively. For example, when the second communication module is in a closed state, the first communication module may be in an active state of searching for a wake-up signal.

[0068] In some embodiments, the first communication module and the second communication module respectively perform different functions to reduce the power consumption of the terminal device. Exemplarily, the first communication module can receive a low power consumption wake-up signal (e.g., LP-WUS) for waking up the second communication module, and the second communication module is used for paging detection.

[0069] As an example, the first communication module is a low-power / low-power signal receiving module, and the second communication module is a main communication module of the terminal device. For example, the first communication module belongs to LP-WUR, and the second communication module belongs to MR. For another example, the first communication module is a low-power wake-up receiver (WUR), and the second communication module is MR.

[0070] As an example, the first communication module may adopt any of the receiver architectures described above, such as Figures 2 to 4 Any of.

[0071] In some embodiments, the terminal device may include the LP-WUR or a module with similar functions described above to monitor the LP-WUS. The module for monitoring the LP-WUS is the first communication module.

[0072] In some embodiments, the terminal device may be one of any terminal device group or subgroup. As an example, the terminal device may be any terminal device in the first terminal device subgroup. That is, when the first terminal device subgroup includes multiple terminal devices, the terminal device may be one of the multiple terminal devices. As an example, the terminal device may be any terminal device in the first terminal device group. The first terminal device group may be divided into multiple terminal device subgroups. The first terminal device subgroup to which the terminal device belongs may be configured or may change dynamically.

[0073] As an example, the first terminal device group may be some or all terminal devices in an idle or inactive state in a certain area. The multiple terminal devices in the first terminal device group may be divided based on different characteristics to determine multiple device subgroups, which is not limited here.

[0074] Exemplarily, the plurality of terminal device subgroups may be determined based on a wake-up delay of a main communication module of the terminal device. Exemplarily, the plurality of terminal device subgroups may also be determined based on a service type or service priority of the terminal device.

[0075] The wake-up signal or paging message monitored by the terminal device comes from the network device. The network device can provide services for the cell where the terminal device is located. The network device can be any base station or core network device described above, and is not limited here. For example, the network device can be any base station described above.

[0076] In some embodiments, the service cell where the terminal device is located is a cell or microcell where the network device can provide services, which is not limited here.

[0077] In some embodiments, the network device may be a communication device supporting the LP-WUS function. For example, the network device may periodically send the LP-WUS to wake up the terminal device. For example, the network device may implement an energy-saving configuration in which the LP-WUS is associated with the PO.

[0078] As an example, the cell served by the network device is an NTN cell. For example, the network device may be a satellite in the NTN that covers the area where the terminal device is located, or may be a ground gateway or ground network device in the NTN that communicates with the satellite.

[0079] In some embodiments, the terminal device and the network device may be relative. For example, relative to the network device, the relay device may also be referred to as the terminal device. For example, relative to the terminal device, the relay device may also be referred to as the network device.

[0080] In some embodiments, the network device may send a paging message to all terminal devices in the serving cell. When the network device is an access network device such as a base station, the network device may directly send a paging message or receive a paging message sent by the core network. When the network device is a core network device, the network device may send a paging message to the access network device so that the access network device can send a paging message to the terminal device.

[0081] See also Figure 5 In step S510, the terminal device determines whether to perform a communication mode conversion based on the first condition. The communication mode conversion may also be referred to as a communication state conversion. The communication mode conversion may indicate that the terminal device converts from a current communication mode to a new communication mode to achieve different communication requirements of the terminal device. It can be seen that the communication mode conversion performed by the terminal device involves at least two different communication modes.

[0082] In some embodiments, executing the communication mode conversion can be replaced by converting from the first communication mode to the second communication mode. In other words, the communication mode conversion refers to the conversion between any different communication modes. The first communication mode is the communication mode of the terminal device at the current moment. The second communication mode is the communication mode that the terminal device needs to execute later.

[0083] Exemplarily, different communication modes of the terminal device may refer to different communication modules of the terminal device for communication. For example, the first communication mode is communicated by the first communication module, and the second communication mode is communicated by the second communication module.

[0084] Exemplarily, different communication modes of a terminal device may refer to different communication services that the terminal device needs to perform. For example, in the first communication mode, the first communication module performs wake-up signal monitoring, in the second communication mode, the first communication module does not perform wake-up signal monitoring, in the third communication mode, the second communication module performs paging detection, and in the fourth communication mode, the second communication module does not perform paging detection.

[0085] Exemplarily, in different communication modes of the terminal device, different communication modules of the terminal device are in different states. For example, in the first communication mode, the second communication module of the terminal device is in a closed state, and in the second communication mode, the second communication module of the terminal device is in an active state. For another example, in the first communication mode, the first communication module of the terminal device is in an active state, and in the second communication mode, the first communication module of the terminal device is in a closed state.

[0086] In some embodiments, the communication mode conversion is related to whether the first communication module monitors the communication mode of the wake-up signal. In the embodiment of the present application, the wake-up signal monitoring is performed by the low-power first communication module (eg, LP-WUR).

[0087] As an example, the communication mode conversion includes the first communication module entering the wake-up signal monitoring mode and the first communication module exiting the wake-up signal monitoring mode. It can be seen that the first condition can be used as a condition for the terminal device to activate / deactivate the first communication module to enter / exit the wake-up signal monitoring.

[0088] In some embodiments, the wake-up signal is used to wake up the second communication module of the terminal device. As can be seen from the foregoing, the second communication module of the terminal device is the main communication module. Waking up the main communication module through the wake-up signal can facilitate the terminal device to enter a deep sleep state or an ultra-deep sleep state, thereby achieving energy saving of the terminal device.

[0089] In some embodiments, the wake-up signal may be the LP-WUS described above or a signal with a similar function to the LP-WUS. For the sake of brevity, the following description will take the LP-WUS as an example.

[0090] As an example, the wake-up signal may be one or more LP-WUSs associated with the terminal device. Optionally, one LP-WUS may be used to indicate whether one or more terminal devices are awakened. Multiple terminal devices awakened by one LP-WUS may belong to a terminal device group or a terminal device subgroup.

[0091] As an example, the terminal device can monitor and receive a wake-up signal through the first communication module so as to wake up the second communication module that performs paging detection before the paging message arrives. The second communication module being awakened may refer to converting the second communication module from an off state to an active state, or may refer to triggering the second communication module to monitor the paging message.

[0092] It should be understood that since the first communication module of the terminal device can be independent of the terminal device, the awakening of the second communication module can also be referred to as the awakening of the terminal device. Before receiving the wake-up signal, the second communication module can be in a closed state. The terminal device can determine whether to wake up the second communication module based on the received wake-up signal. Optionally, the wake-up signal can also be used to wake up other modules in the terminal device except the second communication module.

[0093] In some embodiments, before determining whether to perform the communication mode conversion, the terminal device also needs to check whether the serving cell supports the transmission of the wake-up signal. For the network equipment of the serving cell, the network equipment can determine whether to send the wake-up signal to the terminal device based on the paging of the terminal device. As an example, the information on whether the serving cell supports LP-WUS transmission can be included in the system information sent by the base station.

[0094] As an example, when the serving cell supports LP-WUS transmission, the terminal device can determine whether to perform communication mode conversion based on system information and the configuration of its own LP-WUS monitoring occasion (MO). For example, the terminal device can determine whether to monitor LP-WUS through the first communication module or enter the second communication module to detect paging messages on the paging occasion (PO) according to the configuration of the MO.

[0095] The first condition is used to determine whether the terminal device performs communication mode conversion, and the first condition may also be referred to as a communication mode conversion condition. Therefore, the first condition may include a condition for the terminal device to convert between any two communication modes.

[0096] As an example, the first condition can be used to activate the first communication module to enter the wake-up signal monitoring mode. That is, the first condition can be used as an entry condition for the terminal device to decide to detect the wake-up signal. For example, if the terminal device decides to monitor LP-WUS based on the entry condition, the entry condition needs to ensure that the terminal device can receive LP-WUS or similar signals (for example, LP-SS described later) without lack of coverage when the main radio (main communication module) is in an ultra-deep sleep state. For another example, when the current state of the terminal device meets the first condition, the terminal device can activate the first communication module to monitor the wake-up signal.

[0097] As an example, the first condition may be used to deactivate the first communication module to enter the wake-up signal monitoring mode. For example, when the current state of the terminal device does not meet the first condition, the terminal device may cancel monitoring of the wake-up signal.

[0098] As an example, the first condition can be used to activate the first communication module to exit the wake-up signal monitoring mode. That is, the deactivation of the wake-up signal monitoring can be initiated by the terminal device. For example, when the terminal device cannot successfully receive LP-WUS or LP-SS due to the limited coverage of the first communication module, the terminal device can trigger a fallback operation to exit the current wake-up signal monitoring mode. For another example, when the current state of the terminal device meets the first condition, the terminal device can instruct the first communication module to no longer monitor the wake-up signal.

[0099] As an example, the first condition may be used to deactivate the first communication module to exit the wake-up signal monitoring mode. For example, when the current state of the terminal device does not meet the first condition, the terminal device may continue to monitor the wake-up signal.

[0100] As an embodiment of the above example, when the first condition indicates that the first communication module exits the wake-up signal monitoring mode, the timing of the communication mode conversion is related to the wake-up time of the second communication module and / or the type of the first communication module. For example, the terminal device can determine the timing of executing the communication mode conversion based on the wake-up time of the second communication module from the deep sleep state to the awakened state and the type of the first communication module to improve communication efficiency.

[0101] As an example, the first condition may include system information instructing the terminal device to perform communication mode conversion and / or configuration of the LP-WUS MO of the terminal device.

[0102] The first condition is related to the first measurement result. The first measurement result is related to the measurement signal. In some embodiments, the first measurement result may include the result after the first communication module and / or the second communication module measures the measurement signal. In some embodiments, the first measurement result may include signal quality based on a low-power (LP) mechanism to achieve energy saving. For example, when the signal quality is represented by a reference signal received power (RSRP), the first measurement result measured based on the low-power mechanism can be represented as LP-RSRP. LP-RSRP can also be replaced by RSRP. It should be understood that other signal quality parameters can also be represented in a similar manner.

[0103] In some embodiments, the measurement signal corresponding to the first measurement result may be one of the following: a wake-up signal, a synchronization signal related to the first communication module, and a synchronization signal block. The wake-up signal may be the LP-WUS described above.

[0104] As an example, the synchronization signal associated with the first communication module may be a synchronization signal (low-power synchronization signal, LP-SS) sent when the network device supports a low power mechanism, and therefore may also be referred to as a low power synchronization signal. That is, when the network device supports LP-WUS energy saving, LP-SS may be sent to facilitate synchronization of the first communication module. Optionally, the terminal device may perform LP-SS-based measurements to save power.

[0105] As an example, the terminal device may determine the configuration information of the LP-SS in a variety of ways. As an implementation, the network device may directly configure the LP-SS identity (ID) and / or the LP-SS binary sequence in the broadcast information. As another implementation, the terminal device may identify the LP-SS based on a preconfigured rule. The preconfigured rule may be: the LP-SS identity is equal to (physical cell ID) modulo (the number of configured candidate LP-SS sequences). In this implementation, by appropriately configuring the number of candidate LP-SS sequences, the network device may manage interference between cells in a local area that send the same LP-SS sequence.

[0106] As an example, the synchronization signal block may be an SSB including PSS / SSS, or may be PSS / SSS. The terminal device may obtain better accuracy by performing SSB-based measurement.

[0107] In some embodiments, the time domain resources of the measurement signal are aligned with the time domain resources for synchronization of the second communication module, so that the second communication module can be aligned in time after being awakened.

[0108] As an example, the time / frequency resource grid of LP-WUS and LP-SS can also help the second communication module to perform initial timing / frequency calibration. For example, if the timing edge of LP-WUS is specified to be aligned with the edge of the symbol / time slot / frame of the traditional NR system, the second communication module can immediately obtain symbol / time slot / frame level synchronization when it is turned on.

[0109] In some embodiments, the terminal device may determine whether to perform a communication mode conversion based on the first measurement result of the above-mentioned measurement signal. The terminal device may measure the quality of LP-WUS transmission based on LP-WUS and / or LP-SS, or even PSS / SSS, and therefore, the first measurement result may be used to indicate the transmission quality of the wake-up signal. It can be seen that the two communication modules of the terminal device may measure the quality of the received signal based on LP-WUS, LP-SS, and / or PSS / SSS.

[0110] As an example, when the terminal device performs measurement through the first communication module, the type of the first communication module is related to the measurement signal that the terminal device can measure. For example, different terminal devices can apply different types of LP-WUR. Different types of LP-WUR can receive or measure different types of measurement signals.

[0111] As an implementation method, the type of the first communication module may include a first type and a second type. When the type of the first communication module is the first type, the measurement signal corresponding to the first measurement result includes a wake-up signal and / or a synchronization signal related to the first communication module; when the type of the first communication module is the second type, the measurement signal corresponding to the first measurement result includes a synchronization signal block. For example, LP-WUR can be divided into the following two different types: LP-WUR type 1 and type 2. Among them, the first communication module of LP-WUR type 1 (first type) cannot receive OFDM sequences, and the first communication module of LP-WUR type 2 (second type) can receive OFDM sequences. Taking into account the differences between the two different types of LP-WUR, different first conditions (communication mode conversion conditions) can be specified. Therefore, different types of LP-WUR will affect the activation / deactivation process of the terminal device.

[0112] In the above implementation, when receiving LP-WUS based on OOK symbols, LP-WUR type 2 can receive the existing PSS / SSS and / or superimposed OFDM sequence. Due to the possibility of sequence detection, LP-WUR type 2 may have better coverage. For example, if the terminal device has a LP-WUR of type 2, the terminal device can receive an indication of the LP-WUS by combining the OFDM sequence and the OOK symbol. If the LP-WUR of type 2 can perform energy detection and sequence detection, the terminal device with LP-WUR type 2 can perform two or only one detection to receive the LP-WUS.

[0113] In the above implementation, the terminal device can perform radio resource management (RRM) measurements by receiving LP-SS and / or PSS / SSS, which will be described in detail below in conjunction with RRM measurements. For example, when LP-WUR can receive PSS / SSS, the terminal device can perform measurements based on the received PSS / SSS. As another example, the terminal device can perform LP-SS-based measurements to save power. As another example, the terminal device can decide whether to wake up the second communication module to receive paging based on the LP-SS measurement and the received paging early indication (PEI) indication.

[0114] The first condition is related to the first measurement result indicating the transmission quality of the wake-up signal, so that the terminal device determines whether to enter / exit the wake-up signal monitoring mode according to the predicted / measured transmission quality of the wake-up signal. Optionally, the first measurement result can directly indicate the transmission quality of the wake-up signal, can also indirectly indicate the transmission quality of the wake-up signal, and can also predict the transmission quality of the wake-up signal.

[0115] In some embodiments, the terminal device may determine whether to enter the wake-up signal monitoring mode based on the first condition or determine whether to exit the wake-up signal monitoring mode based on the first condition. It should be understood that the determination conditions for the terminal device to enter / exit the wake-up signal monitoring mode may be different. In this scenario, the first condition may include a second condition for entering the wake-up signal monitoring mode and a third condition for exiting the wake-up signal monitoring mode. It can be seen that the second condition can be used to instruct the terminal device to activate / deactivate the first communication module to enter the wake-up signal monitoring mode. The third condition can be used to instruct the terminal device to activate / deactivate the first communication module to exit the wake-up signal monitoring mode.

[0116] In some embodiments, when the first measurement result satisfies the second condition, the first communication module is activated to enter the wake-up signal monitoring mode or the second communication module is turned off. When the first measurement result does not satisfy the second condition, the first communication module is deactivated to enter the wake-up signal monitoring mode or the current state of the second communication module is maintained.

[0117] In some embodiments, the second condition may be associated with the first threshold value so that the terminal device determines whether to enter the wake-up signal monitoring mode according to the first measurement result of the measurement signal. Before entering the wake-up signal monitoring, the second communication module (MR) is usually not in a sleep state, so the second communication module can perform the service cell measurement based on the measurement signal. Based on the measurement result and the first threshold value, it can be decided whether to perform the transition of the second communication module to the ultra-deep sleep state, the operation of the first communication module, and whether to activate LP-WUS monitoring.

[0118] Optionally, the first threshold may be used as an entry threshold for entering LP-WUS monitoring. That is, the first threshold may be regarded as a standard for the terminal device to start monitoring LP-WUS. For the first threshold, in addition to the absolute measurement threshold (such as the signal quality threshold), the measured change value should also be considered to reflect the situation of sufficient and stable coverage.

[0119] As an embodiment, the first threshold value may be one or more of the following: a signal quality threshold value associated with the second communication module; a threshold value for a change in the signal quality associated with the second communication module over a period of time (e.g., a first time period); or a signal quality threshold value associated with the second communication module within the first frequency band.

[0120] In the above embodiments, the signal quality may be represented by RSRP, reference signal received quality (RSRQ), received signal strength indication (RSSI) or other quality parameters. The first time period may be configured by higher layer signaling. The first frequency segment is, for example, a frequency segment or frequency interval related to the operating frequency of the first communication module.

[0121] As an implementation method, the first threshold can be one of the following thresholds: an MR RSRP threshold; an MR RSRP change threshold within a first time period; an MR RSRP threshold and an MR RSRP change threshold within the first time period; an MR RSRP / RSRQ threshold measured in a first frequency segment or between frequencies.

[0122] In some embodiments, when the first measurement result satisfies the third condition, the first communication module is activated to exit the wake-up signal monitoring mode or wake up the second communication module. When the first measurement result does not satisfy the third condition, the first communication module is deactivated to exit the wake-up signal monitoring mode or maintain the current state of the second communication module.

[0123] In some embodiments, the third condition may be related to the second threshold so that the terminal device determines whether to exit the wake-up signal monitoring mode based on the first measurement result of the measurement signal. Before exiting the wake-up signal monitoring, the first communication module (LR) is active, so the service cell measurement based on the measurement signal can be performed by the first communication module. In addition, when the terminal device enters LP-WUS monitoring, the MR measurement needs to be relaxed or completely turned off. If the MR measurement result is applicable (for example, based on a relaxed measurement result), the LR can also know this result and assist it in exiting the LP-WUS monitoring.

[0124] Optionally, the second threshold may be used as an exit threshold for whether to exit LP-WUS monitoring. That is, the second threshold may be set with reference to measurement changes similar to the first threshold.

[0125] As an embodiment, the second threshold value may be one or more of the following: a signal quality threshold value associated with the first communication module; a change threshold value of the signal quality associated with the first communication module within a period of time (e.g., a second time period); a signal quality threshold value associated with the second communication module. In this embodiment, the signal quality may also be represented by RSRP, RSRQ or other parameters. The second time period may be configured by higher layer signaling.

[0126] As an implementation manner, the second threshold may be one of the following thresholds: an LR RSRP threshold; an LR RSRP change threshold within the second time period; an LR RSRP threshold and an LR RSRP change threshold within the second time period; an LR RSRP threshold and an MR RSRP threshold.

[0127] For ease of understanding, the following Figure 6 An exemplary method for executing communication mode conversion of a terminal device is described. Figure 6 The second or third condition in belongs to the first condition. Figure 6 The method shown is executed by a terminal device.

[0128] See also Figure 6 , in step S610, a first measurement result is determined.

[0129] In step S620, it is determined whether the first measurement result satisfies the second condition or the third condition.

[0130] In step S630, when the first measurement result meets the second condition, the first communication module is activated to enter the wake-up signal monitoring mode or the second communication module is turned off.

[0131] In step S640, when the first measurement result meets the third condition, the first communication module is activated to exit the wake-up signal monitoring mode or wake up the second communication module.

[0132] Combination of the above Figure 6 A method for a terminal device to switch a communication mode based on a second condition or a third condition is introduced. For a network device, when a first measurement result satisfies the second condition, the network device can determine whether to send a wake-up signal to the terminal device according to the paging situation of the terminal device; or, when the first measurement result satisfies the third condition, the network device can determine whether to send a paging message to the terminal device according to the paging situation of the terminal device.

[0133] In some embodiments, the first condition further includes one or more of the following: whether the first communication module receives a wake-up signal within a third time period; whether the second communication module needs to be woken up regularly; whether the terminal device needs to perform cell reselection / switching. Exemplarily, the terminal device can perform communication mode conversion according to any one or any multiple of these conditions.

[0134] Exemplarily, the terminal device may determine whether to perform a communication mode conversion based on the situation in which the first communication module monitors the wake-up signal. When the terminal device moves out of the coverage of LP-WUS and LP-SS, the network device cannot wake up the second communication module of the terminal device through LP-WUS. Therefore, one of the exit conditions of LP-WUS monitoring may be that the terminal device is not within the coverage of LP-WUS and LP-SS. Specifically, when the terminal device does not receive LP-WUS within the configured duration, in order to avoid losing the paging message, the second communication module should be woken up to find out whether there is any paging message for the terminal device.

[0135] Exemplarily, the situation in which the first communication module monitors the wake-up signal may include whether the first communication module receives the wake-up signal within a third time period. The third time period may be a duration period configured by a higher layer to monitor whether the wake-up signal is received. In this scenario, the first condition may be a fallback condition related to the third time period. When the fallback condition is met, the terminal device stops monitoring the LP-WUS.

[0136] As an example, the communication mode conversion may include the second communication module entering the paging monitoring mode. When the first communication module does not receive the wake-up signal within the third time period, the second communication module is activated to enter the paging monitoring mode.

[0137] Exemplarily, in some scenarios, the second communication module of the terminal device may need to be awakened periodically to prevent the main communication module of the terminal device from remaining in an ultra-deep sleep state for a long time. As an example, when the first condition indicates the periodicity at which the second communication module needs to be awakened, the terminal device may perform a communication mode conversion according to the periodicity.

[0138] As an example, the condition that the second communication module needs to be awakened periodically may also be related to the first measurement result. For example, when the first measurement result shows that the wake-up signal transmission quality is good, the second communication module needs to be awakened periodically. For another example, when the first measurement result shows that the wake-up signal transmission quality is poor, the second communication module does not need to be awakened periodically.

[0139] Exemplarily, when the first condition indicates that the terminal device needs to perform cell reselection / switching, the terminal device may perform communication mode conversion. For example, when the terminal device needs to perform cell reselection / switching, the terminal device may wake up the second communication module.

[0140] As an example, when the first measurement result includes a measurement result of the SSB, the terminal device may determine whether to wake up the second communication module according to the measurement result of the SSB to perform cell reselection or cell switching. For example, the terminal device may decide whether to wake up the MR based on the measurement result of the SSB to perform cell switching.

[0141] As an example, when the first measurement result includes a measurement result of an LP-SS, the terminal device may also determine whether to perform a cell switching according to the measurement result of the LP-SS.

[0142] In some embodiments, the first measurement result may be a result of measuring a measurement signal within a first time window. Exemplarily, the first measurement result may be a result of the first communication module measuring the LP-SS. The network device may indicate the transmission resource of the LP-SS by configuring the first time window so that the terminal device can determine the measurement signal.

[0143] As an example, for the measurement of LP-SS, the configuration of the time window (first time window) may be considered to explicitly indicate the resources of the LP-SS. Exemplarily, the window of the first time window may limit the resource size of the LP-SS for measurement purposes. By configuring the first time window, the terminal device does not need to measure each LP-SS.

[0144] As an example, the LP-SS transmissions restricted to the first time window may be transmissions dedicated for measurement purposes.

[0145] As an example, the first time window may be configured by higher layer signaling. Exemplarily, the higher layer signaling may directly configure the starting position and the ending position of the first time window. Exemplarily, the higher layer signaling may configure a specific time slot or symbol resource as the first time window. Further, the time slot position of the first time window and the symbol position within the time slot may be determined by higher layer signaling.

[0146] Taking the LP-RSSI measurement for implementing the low power consumption function as an example, the frequency resource of the measurement signal for determining the LP-RSSI can be set to the entire bandwidth (BW), and the time resource of the measurement signal for determining the LP-RSSI may be limited to the time configuration of the LP-SS. In this example, the entire bandwidth is, for example, 5MHz. The LP-RSSI can be determined by measuring all symbols in the first time window. Alternatively, the time resource of the measurement signal for determining the LP-RSSI can be limited to a specific symbol.

[0147] In some embodiments, after the first communication module enters the wake-up signal monitoring mode, the terminal device can also determine whether to perform a communication mode switch or a cell switch based on the first measurement result. The terminal device has already resided on the cell before entering the wake-up signal monitoring mode. After the terminal device enters the wake-up signal monitoring mode, the first communication module can measure the service cell based on LP-SS in certain discontinuous reception (DRX) cycles, and the second communication module switches to an ultra-deep sleep state without performing measurements. These DRX cycles measured based on LP-SS can be certain DRX cycles where the second communication module initially performs measurements.

[0148] As an example, when the type of the first communication module is the first type described above, the first communication module can determine whether to perform cell switching or communication mode conversion based on the measurement result of the LP-SS (i.e., the first measurement result) and multiple thresholds. Exemplarily, when the first measurement result is greater than or equal to the set third threshold (threshold 1), the terminal device can activate the first communication module based on the first measurement result to perform cell switching. The cell switching can be performed when the second communication module is in a deep sleep state, thereby switching to the target cell. When the first measurement result is lower than the third threshold and higher than the set fourth threshold (threshold 2), the terminal device may not perform communication mode conversion. In other words, the first measurement result may not be used as a basis for cell switching. However, the terminal device still does not wake up the second communication module, but still resides in the wake-up signal monitoring state. When the first measurement result is lower than or equal to the fourth threshold, the terminal device activates the first communication module to exit the wake-up signal monitoring mode and wake up the second communication module. The second communication module can perform measurements and receive paging.

[0149] In the above example, after the first communication module enters the wake-up signal monitoring mode, the network device can also perform corresponding operations according to the first measurement result. When the first measurement result is higher than or equal to the third threshold, the network device can receive the cell switching request sent by the terminal device; when the first measurement result is lower than the third threshold and higher than the fourth threshold, the network device can determine whether to send a wake-up signal according to the paging situation of the terminal device; when the first measurement result is lower than or equal to the fourth threshold, the network device can determine whether to send a paging message according to the paging situation of the terminal device.

[0150] Optionally, during the process of the first communication module performing cell switching, the cell switching may share a random access channel occasion (RO) and resources associated with the second communication module performing cell switching.

[0151] Optionally, the fourth threshold in the above example may be equal to the second threshold mentioned above.

[0152] Combination of the above Figure 5 and Figure 6 A method for executing communication mode conversion based on multiple first conditions of a terminal device is introduced. When the first condition indicates that the terminal device exits the wake-up signal monitoring mode, the terminal device can wake up the second communication module, thereby performing related communication through the second communication module. However, the terminal device needs a sufficiently large offset to switch from the operation of low power wake-up occasion (LP-WUS occasion, LO) monitoring to the second communication module wake-up.

[0153] In some embodiments, the conversion time required for the terminal device to perform the communication mode conversion can be determined according to the type of communication mode conversion that the terminal device needs to perform and / or the capability information of the terminal device. Optionally, the capability information of the terminal device can include the wake-up time of the second communication module and the type of the first communication module.

[0154] In some embodiments, the terminal device may determine the type of communication mode conversion to be performed according to the first condition. For example, when the first condition indicates that the terminal device performs a first communication mode conversion, the first communication mode conversion may include the first communication module exiting the wake-up signal monitoring mode and the second communication module being awakened.

[0155] As an example, the first communication mode conversion includes when the first communication module exits the wake-up signal monitoring mode and the second communication module is awakened, and the conversion time of the first communication mode conversion is related to the wake-up time of the second communication module and / or the type of the first communication module.

[0156] Exemplarily, if the second communication module needs to wake up to monitor PO, the offset time between LO and PO needs to cover the time for the wake-up signal detection, the second communication module wake-up and resynchronization. That is, after the terminal device detects the wake-up signal at LO, the second communication module needs to switch from ultra-deep sleep mode to active mode. This requires a sufficiently large offset time to ensure that the second communication module has enough time to wake up and be ready to monitor the paging indicator (monitor PO).

[0157] As an example, the wake-up time of the second communication module may include a time of switching from an ultra-deep sleep mode to an active mode.

[0158] As an example, the offset time between the wake-up signal detection and the paging monitoring may be the sum of the wake-up signal detection time, the wake-up time of the second communication module, and the resynchronization time. The offset time may be used to determine the conversion time of the first communication mode conversion.

[0159] In some embodiments, different terminal devices may have different switching times. The second communication modules of different terminal devices may be in different sleep states, depending on the location and service type of the terminal device. For example, the switching time of the terminal device may vary from tens of milliseconds (such as deep sleep) to hundreds of milliseconds (such as ultra-deep sleep).

[0160] In some embodiments, the terminal device may also support multiple conversion times related to the communication mode conversion. That is, the terminal device may have different mode conversion times in different scenarios. Optionally, the setting of multiple conversion times may also be related to the capability information of the terminal device. For example, when the first condition indicates that the communication mode conversion performed by the terminal device is a first communication mode conversion, the conversion time corresponding to the first communication mode conversion may be determined according to the capability information of the terminal device.

[0161] As an example, when the first communication module is LP-WUR, multiple conversion times or offset times between PO and LO can be defined based on different LP-WUR types / sleep states or service types of the terminal device.

[0162] As an example, in a scenario where multiple conversion times are defined, the terminal device can report relevant capabilities to the network. For example, when the first condition indicates that the communication mode conversion performed by the terminal device is a first communication mode conversion, the network device can determine the conversion time corresponding to the first communication mode conversion from the multiple conversion times based on the capability information reported by the terminal device.

[0163] As an example, the network device needs to know the transition time required to wake up the second communication module. For example, when the first communication module is LP-WUR and the second communication module is MR, the transition time can be the time from when LP-WUR performs LP-WUS processing to when MR is ready for paging monitoring.

[0164] As described above, the conversion time required for the terminal device to perform a communication mode conversion is related to the type of the first communication module. In some embodiments, different types of first communication modules have an impact on the conversion time of the terminal device. Exemplarily, certain LP-WURs can help reduce the conversion time, so the terminal device can have different conversion times. For example, the synchronization time of the second communication module is also related to the type of the first communication module. The second communication module can use the time and frequency information of the wake-up signal or the measurement signal to reduce the conversion time to reduce the time for the second communication module to perform the resynchronization process. For example, the use of an OFDM receiver can utilize a better oscillator, which has better time / frequency tracking performance than an OOK receiver. Therefore, the resynchronization time of an OFDM receiver may be shorter than that of an OOK receiver.

[0165] In some embodiments, for fast convergence, the network device can be configured through system information and specify the power offset between SSB and LP-WUS / LP-SS. For OOK-based receivers, this offset can help the initial automatic gain control (AGC) to reduce the synchronization time when LP-WUS is turned on. For SSB-based OFDM receivers, this offset can directly help achieve fast AGC for LP-WUS reception. Furthermore, the offset can also support LP-WUS / LP-SS transmission through a subset of all SSB beams.

[0166] The above introduces the method for the terminal device to perform communication mode conversion and the conversion time of the second communication module. Among them, the terminal device can perform communication mode conversion based on the first measurement result. In some embodiments, when the first measurement result is the result of the first communication module measuring the measurement signal, the first measurement result can be used for the first communication module to perform RRM. That is, the first communication module in the terminal device can perform RRM measurement by receiving a wake-up signal, LP-SS and / or PSS / SSS.

[0167] For ease of understanding, the following takes the OOK-based LP-WUR as an example to exemplify the method of performing RRM measurement on the first communication module. For the first communication module based on OOK, the symbols received by the first communication module may include a first symbol and a second symbol. Exemplarily, the first symbol may be an ON symbol in OOK, and the second symbol may be an OFF symbol in OOK. The measured power of the ON symbol may be independent of the sampling rate in the time domain, and the power may include values ​​such as co-channel serving and non-serving cells, adjacent channel interference, thermal noise, and does not include the power of noise and interference. The power measurement of the OFF symbol can be used to estimate the noise and interference power.

[0168] In some embodiments, the terminal device may use LP-RSRP and LP-RSRQ as RRM measurements performed by LP-WUR based on OOK. In this embodiment, the service cell measurement of the main communication module can be relaxed by switching the RRM measurement from the main communication module to LP-WUR. In addition, the measurement accuracy of LP-WUR is high and reliable. If support is provided to relax RRM measurements by using LP-WUR, terminal devices with different types of LP-WUR can perform RRM measurements by receiving LP-SS and / or PSS / SSS.

[0169] As an example, when the LP-WUR can receive the PSS / SSS, the terminal device having the LP-WUR can perform measurements based on the PSS / SSS received by the LP-WUR.

[0170] In some embodiments, the first measurement result may include RSRP. When the RSRP is LP-RSRP measured based on the first communication module, the LP-RSRP may be the RSRP determined by the terminal device after measuring the reference signal under the low power consumption mechanism. Optionally, the measurement band of the LP-RSRP may be refined within the LP-SS band by using filtering, and any power scaling effect caused by filtering should be eliminated.

[0171] As an example, LP-RSRP can reflect the clean LP-SS signal power after the receiver denoises the original received LP-SS waveform. The denoising operation can be performed by subtracting the total received power of the OOK OFF symbol from the total received power of the OOK ON symbol. Depending on how the LP-SS is generated at the network device, the limited LP-SS bandwidth may cause signal power to leak into the OOK OFF symbol. However, this may only affect high signal-to-noise ratio areas, where the absolute accuracy of the measurement is not important for mobility. This signal power leakage can be ignored when the second communication module needs to reselect the signal-to-noise ratio (SNR) area of ​​the adjacent cell.

[0172] As an example, depending on the type of the first communication module, different reference signals may be used for RRM measurement. When the type of the first communication module is the first type, the existing PSS / SSS may be received, and thus the existing measurement metrics based on the synchronization signal may be reused. On the other hand, when the type of the first communication module is the first type, the existing PSS / SSS cannot be received. In order to support RRM measurement based on the first communication module, new LP-RSRP and LP-RSSI measurement metrics need to be defined.

[0173] Optionally, LP-RSRP may be a linear average of the total received power of LP-SS in the first symbol (eg, OOK ON symbol) on a frequency resource defined by the number of resource elements (REs) carrying LP-SS.

[0174] Optionally, the LP-RSSI may be a linear average of the total received power of the LP-SS in the first symbol and the second symbol (eg, OOK OFF symbol) on the frequency resources defined by the number of REs carrying the LP-SS.

[0175] For example, the measured power of an OOK symbol should be independent of the time domain sampling rate, that is, the power can be the average power of one sample or a fixed number of samples. When the type of the first communication module is the first type, LP-RSRP can be defined as the linear average of the received power of the LP-SS in the OOK ON symbol, that is, LP-RSRP = the linear average of the received power of the LP-SS in the OOK ON symbol, in watts.

[0176] As an example, LP-RSRP may be determined by subtracting the linear average of the total received power in the LP-SS OFF symbol (the second symbol) from the linear average of the total received power in the LP-SS ON symbol (the first symbol). For example, assuming that there are N samples per ON / OFF symbol, and the number of ON symbols and OFF symbols are denoted as M1 and M2. If the total power of all samples in one ON symbol or OFF symbol is denoted as P ON (m1) and P OFF (m2), where m1 = 1, 2, ..., M1, m2 = 1, 2, ..., M2. When LP-RSRP is the linear average power of one sample of the ON symbol, the RSRP (i.e., LP-RSRP) can be expressed as:

[0177]

[0178] Wherein, N represents the total number of samples, M1 represents the number of the first symbols, M2 represents the number of the second symbols, and P ON (m1) represents the power of the m1th first symbol, P OFF (m2) represents the power of the m2th second symbol.

[0179] In some embodiments, when performing RRM measurement through the first communication module, the first measurement result may also include RSRQ, i.e., LP-RSRQ. In order to calculate LP-RSRQ, LP-RSSI is also calculated as an intermediate result. As an example, LP-RSRQ may be calculated as follows: LP-RSRQ=LP-RSRP / LP-RSSI.

[0180] As an example, for LP-RSRQ calculation, the LP-RSSI may be determined by a linear average of the total received power in multiple symbols of the LP-SS, which are essentially noise and interference terms.

[0181] As an example, in order to determine LP-RSRQ, one of the following three options may be used as the definition of LP-RSSI. That is, the RSSI measured by the first communication module for RRM may be one of the following three definitions.

[0182] Definition 1: RSSI is the linear average of the power of all symbols received by the first communication module. Exemplarily, LP-RSSI is the linear average of the total received power in all LP-SS OOK symbols. The measured value of LP-RSSI may be affected by the ON / OFF mode. Even if the total number of OOK symbols is the same, the LP-RSSI may be different when the number of ON symbols is different. For example, if LP-SS does not support Manchester coding, the LP-RSSI may be different.

[0183] Definition 2: RSSI is the linear average of the power of the first symbol received by the first communication module. Exemplarily, LP-RSSI is the linear average of the total received power in the LP-SS OOK OFF symbol. LP-RSSI can represent the power of noise and interference.

[0184] Definition 3: RSSI is the linear average of the power of the second symbol received by the first communication module. Exemplarily, LP-RSSI is the linear average of the total received power in the LP-SS OOK ON symbol. LP-RSSI can represent the power of pure signal, noise and interference.
