[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 legacy NR signals and / or other LP-WUS on adjacent subcarriers. RF LNA can be applied to improve sensitivity. Baseband envelope detection ( Figure 4 The ADC (not shown) can be done in the analog domain (before the ADC) or in the digital domain (after the 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 article introduces a variety of LP-WUR architectures and LP-WUS generation methods. When a network device sends an LP-WUS, how the LP-WUR in the terminal device receives the LP-WUS and how to perform paging detection are issues that need to be resolved. For example, when a network device sends an LP-WUS, it can use multi-beams for signal transmission. However, how to send wake-up signals corresponding to multiple terminal devices through multi-beam transmission is an issue that needs to be considered.

[0060] Based on this, an embodiment of the present application proposes a method for wireless communication. Through this method, a first terminal device (for example, UE) can receive a first wake-up signal (for example, LP-WUS) for waking up a second communication module through a first communication module, and perform paging detection through the second communication module. The first monitoring opportunity at which the first terminal device receives the first wake-up signal corresponds to the first beam among multiple beams. Among them, the first wake-up opportunity corresponding to the multiple beams can be allocated as multiple monitoring opportunities to send one or more wake-up signals. It can be seen that based on the design of multiple monitoring opportunities, the network device can perform multi-beam transmission of LP-WUS, thereby improving transmission efficiency.

[0061] For ease of understanding, the following Figure 5 The method proposed in the embodiment of the present application is described in detail. Figure 5 It is introduced from the perspective of the interaction between the first terminal device and the network device.

[0062] The first terminal device is any communication terminal that can receive the wake-up signal, which is not limited here. In some embodiments, the first terminal device can be in an idle state or an inactive state. For example, the first terminal device can be a UE in RRC idle (RRC_IDLE) / RRC inactive (RRC_INACTIVE) mode. In some embodiments, the first terminal device can be in a connected state (CONNECTED).

[0063] In some embodiments, the first 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.

[0064] The first terminal device may include a first communication module and a second communication module. Exemplarily, the first 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 first terminal device. Exemplarily, the first communication module and the second communication module in the first terminal device may be integrated together, but the operating state and / or shutdown state of the two communication modules may be set separately.

[0065] 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.

[0066] In some embodiments, the first communication module and the second communication module respectively perform different functions to reduce the power consumption of the first terminal device. The first communication module receives a first wake-up signal for waking up the second communication module, and the second communication module is used to perform paging detection.

[0067] 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 first 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.

[0068] As an example, the first communication module may adopt any of the receiver architectures described above, such as Figures 2 to 4 Any of.

[0069] In some embodiments, the first 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.

[0070] In some embodiments, the first terminal device may be one of any group or subgroup of terminal devices.

[0071] As an example, the first 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 first terminal device may be one of the multiple terminal devices. As an example, the first 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 first terminal device belongs may be configured or may change dynamically.

[0072] 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.

[0073] Exemplarily, the plurality of terminal device subgroups may be determined based on the wake-up delay of the main communication module of the terminal device. Exemplarily, the plurality of terminal device subgroups may also be determined based on the service type or service priority of the terminal device. Exemplarily, the plurality of terminal device subgroups may also be related to the sequence of the wake-up signal, which will be described in detail later.

[0074] The network device may provide services for the cell where the first terminal device is located. The network device may be any of the network devices described above, and is not limited here. For example, the network device may be any of the base stations described above.

[0075] 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 paging.

[0076] 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.

[0077] 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.

[0078] In some embodiments, the network device may send a wake-up signal for waking up the second communication module to multiple terminal devices based on beam scanning. That is, the network device may send LP-WUS detected by multiple first communication modules corresponding to multiple terminal devices through multiple beams.

[0079] See also Figure 5 In step S510, the first terminal device receives a first wake-up signal sent by the network device. The first wake-up signal may be the LP-WUS described above or a signal with a similar function to the LP-WUS. For simplicity, the following text takes the LP-WUS as an example for introduction.

[0080] In some embodiments, the first wake-up signal is a LP-WUS. A LP-WUS can be used to indicate whether one or more terminal devices are awakened. Multiple terminal devices awakened by a LP-WUS can belong to a terminal device group or a terminal device subgroup.

[0081] As an example, the first wake-up signal may be used for all terminal devices in the first terminal device subgroup.

[0082] The first terminal device can receive the first wake-up signal through the first communication module, so the first communication module is in an active state. In some embodiments, the first communication module can only be used to receive the first wake-up signal, thereby reducing the power consumption of the first terminal device.

[0083] The first wake-up signal is a wake-up signal corresponding to the first terminal device, that is, the first wake-up signal can be used to indicate whether the first terminal device or some modules in the first terminal device are awakened. Whether the first terminal device or some modules in the first terminal device are awakened can refer to converting the communication module from an off state to an active state, or can refer to triggering the communication module to perform paging detection (or monitoring).

[0084] The first wake-up signal is used to wake up the second communication module in the first terminal device. It should be understood that since the first communication module can be independent of the first terminal device, the awakening of the second communication module can also be referred to as the awakening of the first terminal device. Before receiving the first wake-up signal, the second communication module is in a closed state. The first terminal device can determine whether to wake up the second communication module based on the first wake-up signal. In some embodiments, the first wake-up signal can also be used to wake up other modules in the first terminal device except the second communication module.

[0085] In some embodiments, when the first wake-up signal indicates that the first terminal device needs to be woken up, the first wake-up signal can be used to wake up a communication module of the first terminal device that performs paging detection. For example, the first wake-up signal is used to wake up a main communication module that performs paging detection.

[0086] In some embodiments, the first wake-up signal corresponds to a first sequence, that is, the first wake-up signal is used to carry the first sequence. As an example, the network device may transmit the LP-WUS based on the sequence.

[0087] In some embodiments, the first sequence may be one of a plurality of candidate sequences. Exemplarily, the plurality of candidate sequences may constitute a LP-WUS sequence set. Different LP-WUS sequence sets may be transmitted at different times. Exemplarily, the plurality of candidate sequences may include one or more of the following: a dedicated sequence for the first terminal device; a dedicated sequence for a terminal device group or a terminal device subgroup to which the first terminal device belongs; a common sequence.

[0088] As an example, the multiple candidate sequences including the first sequence may include a dedicated sequence of the first terminal device, or referred to as a specific sequence. As an implementation, the multiple candidate sequences may all include identification (ID) information of the first terminal device.

[0089] As an example, the multiple candidate sequences including the first sequence may include a dedicated sequence of a terminal device subgroup (first terminal device subgroup) to which the first terminal device belongs or a terminal device group (first terminal device group) to which the first terminal device belongs. As an implementation, the multiple candidate sequences may all include ID information of the first terminal device subgroup or the first terminal device group.

[0090] As an example, the multiple candidate sequences including the first sequence may include a common sequence. As an implementation, the common sequence may be used to indicate whether all terminal devices that receive the first wake-up signal are awakened. For example, the common sequence may be configured with one or more wake-up conditions. The terminal devices that meet the one or more wake-up conditions are awakened after receiving the first wake-up signal. Accordingly, the terminal devices that do not meet the one or more wake-up conditions will not be awakened after receiving the first wake-up signal.

[0091] As an example, the first sequence is any one of the multiple candidate sequences mentioned above.

[0092] As an example, the first sequence is a combination of any multiple sequences among the multiple candidate sequences. For example, the first sequence may include a dedicated sequence and a common sequence for the first terminal device. For another example, the first sequence includes a dedicated sequence for the first terminal device, a dedicated sequence for the first terminal device group or the first terminal device subgroup, and a common sequence.

[0093] In some embodiments, the division of multiple terminal device subgroups can be implemented in the form of sequences. Exemplarily, when the first sequence corresponds to the first terminal device subgroup, multiple candidate sequences including the first sequence can correspond to multiple terminal device subgroups including the first terminal device subgroup. It can be seen that when a sequence including multiple wake-up information is divided into multiple candidate sequences, each terminal device can determine the terminal device subgroup in which it is located according to the candidate sequence in which the corresponding wake-up information is located.

[0094] In some embodiments, the payload of the first wake-up signal may be determined according to the first sequence. As an example, the payload of the first wake-up signal may be determined according to the type of the first sequence. As an example, the payload of the first wake-up signal may be determined according to the maximum number of information bits of the first sequence. As an example, the payload of the first wake-up signal may be determined according to the transmission mode of the signal.

[0095] As an example, when the maximum number of information bits of the first sequence is 8 bits, the effective load of the first wake-up signal is 8 bits.

[0096] In some embodiments, the first sequence carried by the first wake-up signal can be used to indicate whether multiple terminal devices or multiple terminal device subgroups are awakened. The payload of the first wake-up signal is used to determine the number of terminal devices or terminal device subgroups that can be indicated.

[0097] The first wake-up signal can be sent and received within the time period indicated by the first wake-up opportunity. Relatively speaking, the network device can send the first wake-up signal at the first wake-up opportunity or at the time domain position corresponding to the first wake-up opportunity. The time domain corresponding to the first wake-up opportunity is mainly for scenarios with long communication delays. The first wake-up opportunity can be one of multiple opportunities for receiving / detecting LP-WUS, so the first wake-up opportunity can also be referred to as the first LP-WUS opportunity (LP-WUSoccasion, LO). Exemplarily, the first wake-up opportunity can be a time among multiple wake-up opportunities for the first terminal device to detect LP-WUS, or it can be one of multiple wake-up opportunities for the first terminal device to detect LP-WUS.

[0098] In some embodiments, the first wake-up opportunity may be one wake-up opportunity or multiple consecutive wake-up opportunities. Exemplarily, within one wake-up opportunity cycle, one or more wake-up opportunities for detecting the first wake-up signal may be configured for the terminal device. Exemplarily, within each wake-up opportunity cycle, each LP-WUS may correspond to one wake-up opportunity, or may support multiple wake-up opportunities with consecutive time domain positions.

[0099] Optionally, the first wake-up opportunity may be a dedicated wake-up opportunity or a public wake-up opportunity of the first terminal device, which is not limited here.

[0100] In some embodiments, the first wake-up occasion may be one of multiple wake-up occasions. The allocation of multiple wake-up occasions may be sent to the terminal device via system information. Exemplarily, the allocation of the wake-up occasion may be notified to the terminal device via a system information block (SIB). As an example, the network device may allocate the wake-up occasion based on the configuration of the paging occasion (PO). For example, the PO and the wake-up occasion may correspond one-to-one, or one wake-up occasion may correspond to multiple POs, or multiple wake-up occasions may correspond to one PO. As an example, the terminal device may monitor the wake-up occasion or detect the LP-WUS according to the timing specified by the network device.

[0101] As an example, considering the limited size of the LP-WUS payload, the wake-up opportunity can be used as an identifier of the terminal device. For example, the wake-up opportunity can be allocated based on frequency division multiplexing (FDMed) or time division multiplexing (TDMed) among multiple terminal device groups.

[0102] The first wake-up occasion may include multiple monitor occasions (MO). In other words, the first wake-up occasion may be divided into multiple MOs. Among them, MO may also be referred to as an LP-WUS monitoring occasion. As an example, a monitoring occasion may be defined as a part of the time domain resources used to transmit LP-WUS. For example, when the time domain resources configured for LP-WUS to be transmitted to LP-WUR are M OFDM symbols, a monitoring occasion may occupy M / 6 OFDM symbols. Based on the above definitions of wake-up occasions and monitoring occasions, it can be determined that the LP-WUS monitoring in the idle / inactive mode is performed periodically in a duty cycle manner. That is, the terminal device may periodically monitor the LP-WUS at the wake-up occasion or one or more monitoring occasions in the wake-up occasion.

[0103] As an example, when one wake-up opportunity includes K monitoring opportunities (K is a positive integer), the network device may use these monitoring opportunities in different ways according to system design and required functions.

[0104] The multiple monitoring opportunities in the first wake-up opportunity can be configured based on a variety of factors. Exemplarily, the multiple monitoring opportunities can be configured based on the division of the terminal device subgroups. Exemplarily, the multiple monitoring opportunities can be configured based on the multiple beams corresponding to the wake-up signal. Exemplarily, the multiple monitoring opportunities can also be configured based on the number of repeated transmissions of the wake-up signal. Figure 6 A schematic description is given.

[0105] In some embodiments, multiple monitoring opportunities can also be configured according to the allocation of multiple POs. That is, multiple monitoring opportunities can directly correspond to multiple POs, for example, POs and monitoring opportunities can correspond one to one, or one monitoring opportunity corresponds to multiple POs, or multiple monitoring opportunities correspond to one PO.

[0106] As an example, the network device may allocate multiple monitoring opportunities in one wake-up opportunity based on the location of the PO. For example, the first monitoring opportunity may be determined according to one or more POs corresponding to the first terminal device.

[0107] In some embodiments, the first wake-up signal may occupy one or more monitoring occasions. Exemplarily, each monitoring occasion may be used to send one LP-WUS. Exemplarily, multiple monitoring occasions are used to send one LP-WUS.

[0108] As an example, the number of monitoring opportunities occupied by one LP-WUS may be determined according to a higher layer configuration.

[0109] The plurality of monitoring occasions are used to send at least one wake-up signal. In some embodiments, the plurality of monitoring occasions may send a wake-up signal repeatedly. In some embodiments, the plurality of monitoring occasions may send a plurality of wake-up signals respectively.

[0110] As an example, when one wake-up signal occupies multiple monitoring opportunities, multiple monitoring opportunities can be used to send one wake-up signal.

[0111] As an example, when one wake-up signal occupies one monitoring opportunity, multiple monitoring opportunities can be used to send multiple wake-up signals.

[0112] In some embodiments, multiple monitoring occasions may respectively send sequences of different wake-up signals. Exemplarily, different LP-WUS sequences (sets) may be transmitted in different LP-WUS monitoring occasions, thereby supporting more terminal device subgroups corresponding to each PO. In other words, the network device may transmit multiple sequences in different LP-WU monitoring occasions at the same wake-up occasion.

[0113] In some embodiments, each of the multiple monitoring opportunities may correspond to one or more terminal device subgroups. For example, each LP-WUS monitoring opportunity is mapped to one or more terminal device subgroups. Each terminal device may selectively monitor the LP-WUS monitoring opportunity based on the division of the terminal device subgroups. Exemplarily, each monitoring opportunity may be mapped to different terminal device subgroups, respectively. Exemplarily, each monitoring opportunity may be mapped to multiple terminal device subgroups, for example, each monitoring opportunity may be mapped to a portion of the entire subgroup, and low false alarms may be achieved by limiting the number of terminal device subgroups mapped to one monitoring opportunity.

[0114] As an example, each monitoring opportunity may indicate one or more subgroups to be triggered.

[0115] As an example, each monitoring opportunity may indicate multiple terminal device subgroups that need to be awakened in the entire terminal device subgroup. As an implementation, when the first monitoring opportunity corresponds to multiple terminal device subgroups including the first terminal device subgroup, the number of terminal device subgroups corresponding to the first monitoring opportunity is determined according to the payload of the first wake-up signal.

[0116] As an example, when a wake-up opportunity includes two monitoring opportunities, one monitoring opportunity can be configured with LP-WUSs corresponding to half of the terminal device subgroups, and the other monitoring opportunity can be configured with LP-WUSs corresponding to the other half of the terminal device subgroups, and other scenarios can be deduced accordingly.

[0117] As an example, each monitoring opportunity can be mapped to a different terminal device subgroup to support low false alarms and trigger multiple terminal devices at the same time. For example, the first monitoring opportunity corresponds to the first terminal device subgroup, and the second monitoring opportunity corresponds to the second terminal device subgroup.

[0118] In some embodiments, the time domain positions of the multiple monitoring opportunities in the first wake-up opportunity are continuous. To facilitate indicating and configuring the multiple monitoring opportunities, the remaining one or more monitoring opportunities may be configured continuously according to the position of the first monitoring opportunity.

[0119] In some embodiments, the time domain positions of the multiple monitoring opportunities are determined based on the time domain position of the first monitoring opportunity in the first wake-up opportunity and the periodicity of the monitoring opportunity. That is, the multiple monitoring opportunities are not designed continuously. The network device can periodically place the remaining one or more monitoring opportunities based on a certain period after the position of the first monitoring opportunity.

[0120] The multiple monitoring opportunities may include the first monitoring opportunity at which the first terminal device receives the first wake-up signal. That is, the first terminal device may receive the first wake-up signal at the first monitoring opportunity. It can be seen that when the first wake-up opportunity is configured to include multiple monitoring opportunities, the first terminal device can selectively detect one or more monitoring opportunities without detecting the entire wake-up opportunity, thereby reducing the power consumption of the terminal device.

[0121] As an example, the first monitoring opportunity may be a timing among multiple monitoring opportunities for the first terminal device to detect LP-WUS, or may be one of multiple monitoring opportunities for the first terminal device to detect LP-WUS.

[0122] In some embodiments, the first monitoring opportunity may be at least one monitoring opportunity among multiple monitoring opportunities. As an example, when the first wake-up signal corresponding to the first monitoring opportunity occupies one monitoring opportunity, the first monitoring opportunity may be one monitoring opportunity. As another example, when the first wake-up signal corresponding to the first monitoring opportunity occupies multiple monitoring opportunities, the first monitoring opportunity may be multiple monitoring opportunities. As an example, when the first wake-up signal corresponding to the first monitoring opportunity is repeatedly sent through multiple monitoring opportunities, the first monitoring opportunity may refer to one or more of the monitoring opportunities.

[0123] In some embodiments, when the first monitoring opportunity includes the first monitoring opportunity in the first wake-up opportunity, the starting time domain position of the first monitoring opportunity is the same as the starting time domain position of the first wake-up opportunity. For example, the first monitoring opportunity is aligned with the starting point of the first wake-up opportunity.

[0124] As an example, the first monitoring opportunity may be the first monitoring opportunity in the first wake-up opportunity.

[0125] As an example, the position of the first monitoring opportunity can be determined according to the positioning method of the first wake-up opportunity. Alternatively, when the first wake-up opportunity includes only one monitoring opportunity, the position of the first monitoring opportunity can be determined according to the positioning method of the single monitoring opportunity.

[0126] The network device may send a first wake-up signal at the first monitoring opportunity or at the time domain position corresponding to the first monitoring opportunity. The time domain corresponding to the first monitoring opportunity is mainly for scenarios with long communication delays. The first monitoring opportunity may be one of multiple monitoring opportunities for the first terminal device to receive / detect LP-WUS, so the first monitoring opportunity is also the first MO.

[0127] In some embodiments, the first monitoring opportunity may be notified to the terminal device by specifying a subgroup of the terminal devices.

[0128] In some embodiments, the first monitoring opportunity is determined according to the index of the PO associated with the first terminal device. That is, the first terminal device can determine the first monitoring opportunity among multiple monitoring opportunities according to the index of the associated PO. Exemplarily, the index of the first monitoring opportunity is determined according to the index of the PO associated with the first terminal device. That is, the index of the first monitoring opportunity among multiple monitoring opportunities can be determined according to the index of one or more POs corresponding to the first terminal device.

[0129] As mentioned above, the network device can send LP-WUS through multiple beams. It can be seen that the first wake-up opportunity for sending LP-WUS corresponds to multiple beams. In order to achieve LP-WUS transmission with fewer resources, the first wake-up opportunity may include multiple monitoring opportunities. For example, multiple beams can be used to divide the first wake-up opportunity into multiple monitoring opportunities. For another example, in each wake-up opportunity, multiple LP-WUS monitoring opportunities can be configured for multi-beam transmission of LP-WUS. In other words, the transmission resources of LP-WUS are further refined to wake up more terminal devices.

[0130] Optionally, the multiple beams may be part or all of the beams of the network device within a beam scanning cycle, which is not limited here.

[0131] As an example, when sending LP-WUS based on the beam scanning mode, the gNB transmits different LP-WUS in different beam directions. Optionally, at least two of the multiple beams transmit different LP-WUS.

[0132] As an example, when sending LP-WUS based on the beam scanning mode, the gNB transmits the same LP-WUS in different beam directions. Optionally, at least two of the multiple beams transmit the same LP-WUS.

[0133] The first wake-up signal may be sent through a first beam among the multiple beams. That is, the first wake-up signal corresponds to the first beam, or the first monitoring opportunity for receiving the first wake-up signal corresponds to the first beam.

[0134] In some embodiments, each beam in the plurality of beams may send a different wake-up signal to a different terminal device subgroup. Exemplarily, when the first terminal device is one of the first terminal device subgroup, the wake-up signals of all terminal devices in the first terminal device subgroup are transmitted via the first beam.

[0135] In some embodiments, multiple wake-up signals including the first wake-up signal may be repeatedly sent through multiple beams or multiple monitoring opportunities to improve coverage. As an example, when at least one wake-up signal sent in multiple monitoring opportunities is the first wake-up signal, the first wake-up signal is repeatedly sent through multiple beams. For example, after K LP-WUS monitoring opportunities are allocated in one wake-up opportunity, the network device may repeat the same information in the K LP-WUS monitoring opportunities.

[0136] In some embodiments, when the at least one wake-up signal includes multiple wake-up signals, the multiple wake-up signals correspond to the multiple beams one by one, that is, each beam in the multiple beams sends a different wake-up signal.

[0137] In some embodiments, the network device may enable beamforming to transmit a sequence-based LP-WUS. In each wake-up opportunity, one or more monitoring opportunities may be configured for each beam. One of the plurality of candidate sequences may be transmitted in the LP-WUS monitoring opportunity of each beam.

[0138] Continue to see Figure 5 In step S520, the first terminal device performs paging detection through the second communication module.

[0139] In some embodiments, the awakened second communication module can perform paging detection on the first paging opportunity. Relatively speaking, the network device can send a paging message corresponding to the first terminal device at the first paging opportunity or at the time domain position corresponding to the first paging opportunity. The time domain corresponding to the first paging opportunity is also for scenarios with longer communication delays.

[0140] As an example, the first paging occasion may be configured by a network device or a higher layer. The first paging occasion may be one or more of a plurality of paging occasions corresponding to the first terminal device. The first terminal device may determine the first paging occasion according to the configuration. After waking up the second communication module, the second communication module may detect a paging message on the first paging occasion.

[0141] As an example, the first paging opportunity can be determined based on the first monitoring opportunity and the configuration parameter. The configuration parameter can be an offset value configured by a higher layer or a calculation parameter specified by the protocol. For example, after the first terminal device receives the first wake-up signal at the first monitoring opportunity, the first paging opportunity can be determined based on the time domain position of the first monitoring opportunity and the configured offset value.

[0142] As an example, the first paging occasion can be determined according to the first monitoring occasion. In this scenario, the first paging occasion can be one of a plurality of dynamically configured paging occasions. That is, the first terminal device can perform paging detection based on the dynamically configured paging occasion.

[0143] As an example, the first terminal device performs paging detection on one or more paging occasions configured by the network device. The first monitoring occasion for receiving the first wake-up signal can be determined based on the one or more paging occasions, which will not be described in detail.

[0144] Combination of the above Figure 5 A method embodiment is introduced in which a first wake-up signal received by a first terminal device at a first monitoring opportunity is sent through a first beam. Based on this method embodiment, the corresponding relationships among a terminal device subgroup, a monitoring opportunity, and a plurality of beams related to sending a wake-up signal are respectively introduced. For example, each wake-up opportunity may be composed of a plurality of monitoring opportunities, so that a wake-up signal of one or more terminal device subgroups is sent through one or more beams. As can be seen from the foregoing, the configuration or design of a plurality of monitoring opportunities may take into account a plurality of factors.

[0145] In some embodiments, the plurality of monitoring occasions included in the wake-up occasion may be determined based on a variety of design factors, which may include beam scanning, repeated transmission of a wake-up signal, grouping of terminal devices, corresponding sequence of wake-up signals, and the like.

[0146] As an example, the structure of the LP-WUS monitoring opportunity included in the wake-up opportunity can correspond to three layers of factors, including beam scanning, repetition, and terminal device subgroup segmentation. At the bottom layer, the monitoring opportunity can correspond to the beam scanning mode, and the network device can design corresponding monitoring opportunities in different beam directions. In addition, the network device can configure time domain repetition for the terminal device so that the terminal device receives and combines LP-WUS from multiple monitoring opportunities to obtain better coverage. Alternatively, the monitoring opportunity can also be used to send different LP-WUS for different terminal device subgroups.

[0147] For ease of understanding, the following Figure 6 The design scheme of LP-WUS monitoring timing is exemplified. Figure 6 The first sequence set and the second sequence set in the LP-WUSMO both include multiple candidate sequences. Multiple candidate sequences can correspond to multiple wake-up signals. The wake-up signals corresponding to the first sequence set and the second sequence set can be sent on multiple different monitoring opportunities (LP-WUSMO). Multiple different monitoring opportunities correspond to different beams, such as beam 0, beam 1, etc. The wake-up signals corresponding to different sequences in the sequence set are sent through different beams. In addition, the wake-up signals of the two sequence sets are repeated twice in the time domain of the monitoring opportunity, that is, the first repetition (1 st repetition) and the second repetition (2 nd repetition).

[0148] like Figure 6 As shown, in the wake-up opportunity, the LP-WUS monitoring opportunity is configured for different beams. In each beam, the LP-WUS monitoring opportunity is configured for LP-WUS repetition. The first sequence set and the second sequence set correspond to the wake-up signals of different terminal device subgroups, respectively. Therefore, the LP-WUS monitoring opportunity is also used to send LP-WUS associated with different terminal device subgroups.

[0149] pass Figure 6 In this manner, the network device can increase the number of terminal device subgroups associated with the LP-WUS in the wake-up occasion without introducing additional paging delay, thereby improving transmission efficiency.

[0150] As can be seen from the foregoing, multiple beams can be used to configure one wake-up opportunity as multiple monitoring opportunities. However, how to determine the number of monitoring opportunities (LP-WUS MO) in each wake-up opportunity is a problem that needs to be solved.

[0151] In some embodiments, the number of monitoring opportunities included in the first wake-up opportunity can be determined based on one or more of the following parameters: the number of beams of multiple beams; the number of repeated transmissions of at least one wake-up signal; the number of monitoring opportunities occupied by a wake-up signal; the number of terminal device subgroups or the number of monitoring opportunities corresponding to each beam in the multiple beams.

[0152] As an embodiment, the number of monitoring opportunities included in the first wake-up opportunity can be determined according to the number of beams of the multiple beams. For example, when the network device sends a wake-up signal through 4 beams within the beam scanning period, the first wake-up opportunity may include 4 monitoring opportunities. The 4 monitoring opportunities may include a first monitoring opportunity for sending a first wake-up signal. The 4 monitoring opportunities can be used to send wake-up signals for 4 terminal device subgroups.

[0153] As an embodiment, the number of monitoring opportunities included in the first wake-up opportunity can be determined based on the number of beams of the multiple beams and the number of monitoring opportunities corresponding to each beam. For example, each wake-up opportunity can be composed of N×K monitoring opportunities, where N is the number of beams corresponding to the LP-WUS, and K is the number of monitoring opportunities corresponding to each beam.

[0154] As an embodiment, the number of monitoring opportunities included in the first wake-up opportunity can be determined based on the number of repeated transmissions of at least one wake-up signal and the number of monitoring opportunities corresponding to each beam. For example, each wake-up opportunity can be composed of N×K monitoring opportunities, where K represents the number of LP-WUS monitoring opportunities corresponding to each beam, and N represents K LP-WUS monitoring opportunities repeated N times, thereby forming an LP-WUS group. For another example, each wake-up opportunity can be composed of N×K monitoring opportunities, where N represents the number of LP-WUS monitoring opportunities corresponding to each beam, and K represents N LP-WUS monitoring opportunities repeated K times, thereby forming an LP-WUS group.

[0155] As a sub-embodiment of the above embodiment, multiple LP-WUS monitoring opportunities in a group correspond to the same beam, and different beams can transmit different information.

[0156] As a sub-embodiment of the above embodiment, different terminal device subgroups may be indicated K times through K LP-WUS monitoring opportunities.

[0157] As a sub-embodiment of the above embodiment, within a group, the LP-WUS monitoring opportunity may be used to transmit the same or different information. Each LP-WUS monitoring opportunity may correspond to each beam or each reference signal.

[0158] As an embodiment, the number of monitoring opportunities included in the first wake-up opportunity can be determined according to the number of monitoring opportunities occupied by a wake-up signal. When a wake-up signal needs to occupy X monitoring opportunities (X is a positive integer), the number of monitoring opportunities included in the first wake-up opportunity can be an integer multiple of X. For example, the number of monitoring opportunities included in the first wake-up opportunity can be one of X, 2X, and 4X. For another example, the monitoring opportunity occupied by a wake-up signal can be included in the K monitoring opportunities corresponding to a beam. In other words, the number of monitoring opportunities occupied by a wake-up signal is less than K.

[0159] As an embodiment, the number of terminal device subgroups corresponding to each beam may be equal to the number of monitoring opportunities corresponding to each beam, or may be an integer multiple of the number of monitoring opportunities corresponding to each beam, or may be a factor of the number of monitoring opportunities corresponding to each beam.

[0160] Combination of the above Figures 1 to 6 , describes in detail the method embodiment of the present application. Figures 7 to 9 , describes the device embodiment of the present application in detail. It should be understood that the description of the device embodiment corresponds to the description of the method embodiment, so the parts not described in detail can refer to the previous method embodiment.

[0161] Figure 7 700 is a schematic block diagram of a device for wireless communication according to an embodiment of the present application. The device 700 may be any of the first terminal devices described above. Figure 7 The illustrated apparatus 700 includes a first communication module 710 and a second communication module 720 .

[0171] Optionally, the first wake-up signal corresponds to a first sequence, and the first sequence is one of multiple candidate sequences, and the multiple candidate sequences include one or more of the following: a dedicated sequence for the first terminal device; a dedicated sequence for the terminal device group or terminal device subgroup to which the first terminal device belongs; and a common sequence.

[0172] Figure 8 800 is a schematic block diagram of another device for wireless communication according to an embodiment of the present application. The device 800 may be any network device described above. Figure 8 The illustrated apparatus 800 includes a sending module 810 and a determining module 820 .

[0173] The sending module 810 may be used to send a first wake-up signal at a first monitoring opportunity, where the first wake-up signal is used to wake up the second communication module of the first terminal device.

[0174] Determination module 820 can be used to determine whether to send a paging message corresponding to the first terminal device; wherein the paging message is detected through the second communication module, the first communication module of the first terminal device is used to receive a first wake-up signal, the first wake-up signal is sent through a first beam among multiple beams, the first wake-up opportunities corresponding to the multiple beams include multiple monitoring opportunities, the multiple monitoring opportunities include a first monitoring opportunity, and the multiple monitoring opportunities are used to send at least one wake-up signal.
