[0002] To reduce power consumption in terminal devices due to periodic paging message detection, some communication systems have introduced low-power wake-up signals (LP-WUS). For example, terminal devices can receive LP-WUS signals sent by network devices through a low-power wake-up module independent of the main communication module. Therefore, how terminal devices perform paging detection based on LP-WUS is a problem that needs to be considered.

[0048] To facilitate understanding, some related technical knowledge involved in the embodiments of this application is first introduced. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0049] With the development of mobile communication technology, the application areas of the Internet of Things (IoT) are gradually expanding. However, without the support of an external power source, 5G IoT devices are difficult to implement in practice. This is because 5G devices in cellular networks consume tens of milliwatts of power even when they are not transmitting or receiving any data. This idle power consumption is due to the fact that 5G devices must perform periodic measurements and check for potential paging messages.

[0050] To reduce the power consumption of terminal devices, NR systems introduce a low-power wake-up module (LP-WUS). The LP-WUS module is also known as a low-power wake-up receiver (LP-WUR) or a low-power wake-up radio (LP-WUR). For example, when the terminal device is idle, it can turn off its main communication module / receiver or put it into deep sleep mode, listening for LP-WUS only through the LP-WUR, thereby reducing the terminal device's power consumption. The terminal device's main communication module / receiver can also be called the main radio (MR), and correspondingly, the LP-WUS module can be simply referred to as LR. When the MR is woken up, the terminal device can enter radio resource control (RRC) connected state. The terminal device's LP-WUR can then be continuously turned on to receive LP-WUS. Therefore, the LP-WUR can operate independently of the 5G device; that is, the 5G device can be turned off while the LP-WUR is active and searching for potential LP-WUS. To ensure low power consumption performance of terminal devices, LP-WUS needs to be embedded into relevant communication systems (e.g., NR systems).

[0051] In some embodiments, LP-WUS can support bandwidths 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 together as a single module. LP-WUR can support various receiver architectures. The following description uses the three receiver architectures shown in Figures 2 to 4 as examples to illustrate LP-WUR.

[0052] Figure 2 is a schematic diagram of an LP-WUR based on radio frequency (RF) envelope detection. The receiver architecture shown in Figure 2 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 digital BB processing 208.

[0053] In the architecture shown in Figure 2, the RF signal is directly converted into a baseband signal via an RF envelope detector. Relatively low power consumption can be achieved due to the absence of a local oscillator (LO) and phase-locked loop (PLL). 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, 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 conventional NR signals and / or other LP WUS from adjacent subcarriers, and to support frequency band and / or carrier tuning.

[0054] Figure 3 shows a schematic architecture of an LP-WUR based on heterodyne architecture with intermediate frequency (IF) envelope detection. The receiver architecture shown in Figure 3 includes a matching network 301, an RF BPF 302, an RF LNA 303, a mixer 304, a receiver-over-frequency (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 processor 312.

[0055] In the architecture shown in Figure 3, the RF signal is converted to an intermediate frequency (IF) signal by an RF mixer with a LO. The IF signal is then converted to a baseband signal via IF envelope detection. Depending on the design, there may be one or more IF stages, achieving lower power consumption by relaxing the accuracy and stability requirements of the LO. This architecture can employ a 1-bit or multi-bit ADC. A high-Q matching network and / or an RF BPF and / or an IF BPF (and / or a BB LPF) can be used to suppress adjacent channel interference or interference from conventional NR signals and / or other LP WUS from adjacent subcarriers. Optionally, the architecture can incorporate components to improve sensitivity, such as an RF LNA and / or an IF AMP and / or a BB AMP. Optionally, the architecture can achieve band and / or carrier tuning by tuning the LO frequency.

[0056] Figure 4 shows a schematic architecture of an LP-WUR based on a homodyne or zero-IF architecture with baseband (BB) envelope detection. The receiver architecture shown in Figure 4 includes a matching network 401, an RF BPF 402, an RF LNA 403, a mixer 404, a receiver-on-a-band (LO) 405, a BB AMP 406, a BB LPF / BPF 407, a 1-bit or multi-bit ADC 408, and a digital BB processor 409.

[0057] In the architecture shown in Figure 4, band and / or carrier tuning can be achieved by tuning the LO frequency. Using a BB BPF / LPF instead of a high-Q matching network and / or an RF BPF allows for more effective and simpler suppression of adjacent channel interference or interference from conventional NR signals and / or other LP WUS on adjacent subcarriers. An RF LNA can be applied to improve sensitivity. Baseband envelope detection (not shown in the figure) can be performed in the analog domain (before the ADC) or the digital domain (after the ADC).

[0058] The above text, with reference to Figures 2 to 4, introduces various LP-WUR architectures. All LP-WUR architectures are applicable to on-off keying (OOK) modulation. Some architectures are also applicable to other modulations, such as frequency-shift keying (FSK).

[0059] OOK is a well-known modulation scheme. OOK allows low-power receivers to implement 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 typically span multiple subcarriers.

[0060] In some embodiments, in an OFDM-based MC-OOK system, network nodes can use coded bits to perform multicarrier amplitude shift keying (MC-ASK) waveform generation to generate a low-power wake-up signal (LP-WUS).

[0061] The preceding text introduced various 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 it performs paging detection are issues that need to be addressed. For example, in NR paging, the Paging Early Indication (PEI) mechanism and the LP-WUS mechanism are two energy-saving mechanisms used in idle / inactive modes; how to combine these two mechanisms for paging is a problem that needs to be considered.

[0062] As an example, a basic UE group sharing a single PO can be formed by selecting the paging frame (PF) and paging occasion (PO) using the UE identity (ID) identifier. If separate subgroups are configured, the PEI in release 17 (R17) can indicate which subgroup is triggered within the group sharing the same PO. However, this subgroup design for R17 PEI is not suitable for LP-WUS. This is because the PEI cycle is relatively long, and PEIs are typically designed to include information from multiple POs. However, LP-WUS can be transmitted more frequently than PEI and PO; therefore, multiple LP-WUS connections may correspond to a single PO.

[0063] Based on this, embodiments of this application propose a method for wireless communication. Through this method, a terminal device (e.g., a UE) can receive a first wake-up signal for waking up a second communication module via a first communication module, and perform paging detection via the second communication module. The first timing for receiving the first wake-up signal is determined based on the wake-up device group associated with the wake-up signal to which the terminal device belongs, while the second timing for performing paging detection is determined based on the paging device group or PO group associated with paging detection. Therefore, this method proposes a new terminal device grouping mechanism suitable for LP-WUS. Paging based on joint grouping of LP-WUS and paging messages can reduce the probability that the network device instructs the terminal device to listen to the paging physical downlink control channel (PDCCH) when not paging.

[0064] To facilitate understanding, the method proposed in the embodiments of this application will be described in detail below with reference to Figure 5. Figure 5 is presented from the perspective of the interaction between the first terminal device and the network device.

[0065] The first terminal device can be any type of communication terminal capable of receiving a wake-up signal, and is not limited thereto. In some embodiments, the first terminal device may be in an idle state or an inactive state. For example, the first terminal device may be a UE in RRC idle (RRC_IDLE) / RRC inactive (RRC_INACTIVE) mode. In some embodiments, the first terminal device may be in a connected state.

[0066] In some embodiments, the first terminal device is a communication terminal in the Internet of Things (IoT). The serving cell where the terminal device is located can be an NTN cell or a terrestrial network (TN) cell.

[0067] 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. Exemplarily, the first and second communication modules 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.

[0068] As an example, the first communication module and the second communication module can be in different states. For instance, when the second communication module is in the off state, the first communication module can be in an active state of searching for wake-up signals.

[0069] In some embodiments, the first communication module and the second communication module 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, while the second communication module performs paging detection.

[0070] As an example, the first communication module is a low-power / low-energy signal receiving module, and the second communication module is the main communication module of the first terminal device. For example, the first communication module can be LP-WUR or belongs to LP-WUR, and the second communication module belongs to MR.

[0071] As an example, the first communication module can adopt any of the receiver architectures described above, such as any of those shown in Figures 2 to 4.

[0072] In some embodiments, the first terminal device may include a module with the LP-WUR or similar functions described above to monitor LP-WUS.

[0073] In some embodiments, the first terminal device may be one of any group or subgroup of terminal devices, as will be described below in conjunction with Figures 6-9.

[0074] Network devices can provide services to the cell where the terminal device is located. The network device can be any of the network devices described above, without limitation. For example, the network device can be any of the base stations described above.

[0075] In some embodiments, the network device may be a communication device that supports LP-WUS functionality. For example, the network device may periodically send LP-WUS signals to wake up terminal devices. For example, the network device may implement energy-saving configurations associated with LP-WUS and the Point of Purchase (PO).

[0076] As an example, the cell served by the network device is an NTN cell. Exemplarily, the network device can be a satellite in the NTN that covers the area where the terminal device is located, or it can be a ground gateway or ground network device in the NTN that communicates with the satellite.

[0077] In some embodiments, terminal devices and network devices can be relative terms. For example, a relay device can also be referred to as a terminal device relative to a network device. For example, a relay device can also be referred to as a network device relative to a terminal device.

[0078] Referring to 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 can be the LP-WUS described above or a signal with similar functionality to LP-WUS.

[0079] The first terminal device can receive the first wake-up signal through the first communication module, therefore, the first communication module is in an active state.

[0080] The first wake-up signal is the 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 have been woken up. Whether the first terminal device or some modules in the first terminal device have been woken up can refer to changing the communication module from a closed state to an active state, or it can refer to triggering the communication module to perform paging detection (or monitoring).

[0081] 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 operate independently of the first terminal device, waking up the second communication module can also be referred to as waking up the first terminal device. Before receiving the first wake-up signal, the second communication module is in a disabled 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 besides the second communication module.

[0082] In some embodiments, the first wake-up signal is used to carry first information, that is, the first wake-up signal carries first information. Exemplarily, the first information may include the ID of the first terminal device to indicate the user to whom the wake-up signal is targeted. Exemplarily, the first information may include an indication of whether the second communication module has been woken up. Exemplarily, the first information may also include relevant information supporting other functions.

[0083] As an example, the ID of the first terminal device can be the ID of the terminal device itself, the ID of the terminal device group to which the first terminal device belongs, or the ID of the terminal device subgroup to which the first terminal device belongs. In the embodiments of this application, the ID of the first terminal device can also be referred to as the ID corresponding to the first terminal device, in order to distinguish it from the ID of the terminal device itself.

[0084] As an example, an indication of whether the second communication module is awakened includes whether the second communication module is triggered to perform paging detection.

[0085] As an example, other features include system information (SI) changes, earthquake and tsunami warning systems (ETWS), or commercial mobile alert services (CMAS).

[0086] As an example, the LP-WUS payload may include an indication of a subgroup or PO group that is the same terminal device group as the PEI subgroup. This subgroup indication can be represented using up to 3 bits (when indicating an index) or 8 bits (when representing an index bitmap). Additionally, orthogonal terminal device subgroups may be introduced, which can receive wake-up signals at different times.

[0087] In some embodiments, the maximum number of information bits carried by LP-WUS is limited. As mentioned earlier, LP-WUS supports a bandwidth of 5-20 MHz. Furthermore, the spectral efficiency supported by LP-WUS cannot match the scenarios of paging PDCCH or PEI. Compared to PDCCH-based signals, spectral efficiency limits the maximum number of information bits that LP-WUS can carry. Therefore, it also limits the maximum number of terminal device subgroups indicated by LP-WUS. For example, the maximum number of terminal device subgroups associated with a certain LP-WUS reception time can be 8.

[0088] As an example, the maximum number of bits for the first piece of information is X bits, where X does not exceed 8 bits or 16 bits.

[0089] As an example, the maximum number of device subgroups associated with the first terminal device is related to the maximum number of bits in the first information. In other words, the maximum number of bits in the first information can be determined based on the maximum number of device subgroups corresponding to the PO associated with the first terminal device. The maximum number of bits in the first information can be replaced with the maximum number of bits in the first wake-up signal. The PO associated with the first terminal device can be replaced with one or more POs corresponding to the first terminal device.

[0090] As an example, the maximum number of device subgroups of the PO associated with the first terminal device can be indicated by the PEI.

[0091] Taking the first device point (PO) as an example, when the first PO is associated with multiple device subgroups, all terminal devices in those subgroups will perform paging detection on the first PO. The maximum number of device subgroups is the maximum number of device subgroups corresponding to the first PO.

[0092] For example, LP-WUS can represent information about one or more device subgroups out of N device subgroups using bitmaps or code points. As one possible implementation, the maximum number of device subgroups (Y) per PO and the maximum number of information bits (Z) per LP-WUS can be configured at a higher level or indicated via PEI.

[0093] As an example, Y can support integer values ​​such as 8, 16, 32, 64, 128, etc.

[0094] As an example, Y and Z can have a one-to-one correspondence. The correspondence between Y and Z is as follows:

[0095] Option 1: Y = 8, Z = 3;

[0096] Option 2: Y = 16, Z = 4;

[0097] Option 3: Y = 32, Z = 5;

[0098] Option 4: Y = 64, Z = 6 or 7;

[0099] Option 5: Y = 256, Z = 8.

[0100] Taking LP-WUS as an example, for RRC_IDLE / RRC_INACTIVE modes, the information carried by LP-WUS may include: an identifier (UE group ID or UE subgroup ID); an indication of whether paging monitoring is triggered; and, if the payload size allows, information to support other functions.

[0101] Taking LP-WUS as an example, in connected mode, the information carried by LP-WUS may include: information about the user from LP-WUS; and instructions to wake up PDCCH monitoring.

[0102] In some embodiments, the first information can be carried in a variety of ways, which will be described later in conjunction with bitmaps and various encoding methods.

[0103] The first terminal device may receive the first wake-up signal at a first opportune moment. The network device may send the first wake-up signal at the first opportune moment or at the time domain location corresponding to the first opportune moment. The time domain corresponding to the first opportune moment is mainly for scenarios with long communication latency. The first opportune moment may be one of multiple opportune moments for receiving / detecting LP-WUS; therefore, the first opportune moment may also be called the first LP-WUS occasion (LO). For example, the first opportune moment is the opportune moment among multiple opportune moments used by the first terminal device to detect LP-WUS.

[0104] In some embodiments, the first timing can be one LO or multiple LOs. For example, within one LO cycle, one or more LOs for detecting the first wake-up signal can be configured for the first terminal device. For example, within each LO cycle, each LP-WUS can correspond to one LO, or multiple LOs can be supported.

[0105] As an example, the first timing signal can be either a dedicated LO (Local Opening Signal) or a common LO (Public Locator). When the first timing signal is a common LO, after the first communication module receives a wake-up signal on the common LO, it temporarily does not wake up the second communication module, but continues to detect the first wake-up signal and / or PEI (Personal Interface) corresponding to the first terminal device. Upon detecting the first wake-up signal or the corresponding PEI, the second communication module is woken up.

[0106] Multiple timings, including the first timing, can be configured in various ways to facilitate determination by the first terminal device. In some embodiments, the first timing can be configured based on the allocation of multiple point locations (POs). Exemplarily, multiple location locations (LOs), including the first timing, can be allocated based on the location of the PO and a configured offset. In some embodiments, the first timing can be configured for one or more LOs in a specified manner.

[0107] In some embodiments, the first timing is determined based on the index of the PO associated with the first terminal device. That is, the first terminal device can determine the first timing among multiple timings based on the index of the associated PO. For example, the index of the first timing is determined based on the index of the PO associated with the first terminal device. When the first timing is the first LO among a plurality of LOs, the first terminal device can determine the index of the first LO that can receive the first wake-up signal among the plurality of LOs based on the index of its associated PO.

[0108] As an example, the index of the first timing point can be the index of the first timing point among all timing points within a period, or it can be the index of the first timing point among all timing points within a specified number of periods.

[0109] As an example, a network device can configure the periodicity of LOs and the number of LOs within a LO cycle. The first terminal device can determine the LO index based on its PO index. For instance, after configuring the periodicity of LOs and the number of LOs within a LO cycle in a gNB, the index i of the first LO associated with the first terminal device in a LO cycle... LO It can be:

[0110] i LO =[(UE_ID mod N)*Ns+i_s] mod N LO ;

[0111] Where UE_ID represents the ID of the first terminal device, N LO It is the number of LOs within a LO cycle, i_s is the PO index corresponding to the first terminal device, and N and Ns are the paging-related parameters broadcast by the gNB (see the formula for calculating the PO index specified in protocol TS 38.304).

[0112] In the example above, gNB does not need to configure the relationship between the offset and different POs; it only needs to configure the quantity N. LO Assuming the LO period equals the period of the DRX (idle DRX, i-DRX) in idle mode, if N LO If the number of POs equals the number of LOs in one i-DRX cycle, then it indicates a one-to-one mapping relationship between LOs and POs; if N LO This is equivalent to half the number of POs in an i-DRX cycle, which means that there is a one-to-two mapping relationship between LOs and POs.

[0113] In some embodiments, the first timing is one of multiple timings (LOs) configured according to the PO. That is, multiple LOs including the first timing are associated with multiple POs. One LO can be mapped to one or more POs. When a first terminal device detects the identifier of a PO in the configured first timing (LO), the first terminal device needs to monitor at least the associated PO based on the mapping. This ensures that the first terminal device can receive paging messages in a specific PO based on the intent of the network device. Thus, through the association between LOs and POs, the terminal device needs to monitor at least the POs associated with the LP-WUS context, where LP-WUS is the signal received by the terminal device indicating wake-up. For the LP-WUS monitoring procedure, determining the location of the PO to be monitored based on the received LO is crucial.

[0114] As an example, there is a one-to-one correspondence between PO and LO, or one LO corresponds to multiple POs, or multiple LOs correspond to one PO.

[0115] As an example, based on the location of the PO and the configured offset, the LO is assigned, and the terminal device can monitor the PO by receiving the LO.

[0116] As an example, multiple LOs are used for terminal devices to receive LP-WUS, so the period of the LOs can also be called the period of LP-WUS.

[0117] As an example, multiple timing points correspond one-to-one with multiple point outputs (POs), and the period of these multiple timing points is the same as the period of discontinuous reception (DRX). In other words, one download location (LO) is associated with one PO, and the LO's period can be the same as the DRX period.

[0118] It should be understood that, from the perspective of the end device, when the LO period can be configured separately from the DRX period, multiple LOs can be mapped to a single PO, thereby allowing for more frequent LP-WUS monitoring opportunities. Furthermore, maintaining the same DRX period allows the end device to receive LP-WUS more frequently without shortening the DRX period.

[0119] In some embodiments, multiple timings including a first timing are configured according to a specified manner. That is, the terminal device can periodically monitor LP-WUS based on a specified location. LP-WUS monitoring is performed periodically in a duty cycle manner. Duty cycle monitoring may lead to a high collision probability, meaning the LO may not have sufficient resources to transmit the required number of LP WUS. To address this issue, it is not necessary to restrict the one-to-one mapping between the LO and PO. Therefore, configuring the LO independently of the PO is also an optional approach. As an example, multiple timings including a first timing can be determined based on the location of the synchronization signal. Exemplarily, network devices or standards can define a configuration similar to the PO for the LO. Exemplarily, when the first timing corresponds to a first reference synchronization signal, the time domain location of the first timing can be determined based on the time domain location of the first reference synchronization signal. This time domain location can be a start location or an end location.

[0120] Optionally, the first reference synchronization signal may be a synchronization signal block (SSB) for reference or a synchronization signal and physical broadcast channel block (SSB).

[0121] Optionally, the first reference synchronization signal can also be a low-power synchronization signal (LP-SS).

[0122] As an example, the first timing for the first terminal device to detect LP-WUS can be determined according to the following formula:

[0123] Where X represents the offset of the first reference synchronization signal, LO offset T represents the offset of the first timing point. LO This indicates the first period corresponding to the first timing, UE_ID represents the ID of the first terminal device, and N LO This indicates the number of opportunities within the first cycle.

[0124] Optionally, the first cycle is the LO cycle. As mentioned above, the LO cycle can be the same as the DRX cycle, or it can be configured separately.

[0125] Optionally, the number of opportunities within the first cycle can be the number of LOs in each LO cycle or the number of LOs in the current LO cycle.

[0126] Optionally, the offset of the first timing is the offset of the first timing relative to the reference signal, which can be configured by the network device. For example, the reference SSB / LP-SS in each i-DRX cycle or LO cycle can also be configured via the gNB. offset It is the LO offset of the first terminal device, which can be determined by the ID of the first terminal device, its group, or its subgroup.

[0127] It should be understood that if sending public information via public LO is supported, the method for determining the first timing can be modified accordingly.

[0128] To facilitate understanding, the formula for determining the first timing is illustrated below with reference to Figure 6. Figure 6 shows two LO cycles, each LO cycle showing two LP-SS / SSBs and one LO (i.e., the first timing). It can be seen that multiple LOs, including the first timing, can be periodically configured based on LO cycles. As shown in any LO cycle of Figure 6, the second LP-SS / SSB is the first synchronization reference signal used for reference; therefore, the offset X of the first synchronization reference signal is one LP-SS / SSB cycle. The time-domain position of the first timing is the sum of the time-domain position of the first synchronization reference signal and the offset, i.e., X + LO. offset .

[0129] The configuration method for the first timing has been described above with reference to Figure 6. The ID of the first terminal device can be the ID of the group or subgroup to which the first terminal device belongs. Therefore, the first timing corresponding to the first terminal device can be determined based on the group or subgroup to which the first terminal device belongs. It should be noted that, provided there is no conflict, the "group" and corresponding "subgroup" to which the first terminal device belongs can be interchanged.

[0130] Since the first timing is used for the first terminal device to receive the first wake-up signal, the group of terminal devices used to determine the first timing is called the first wake-up device group. The wake-up device group can also be called a wake-up group. Therefore, the first wake-up device group is divided based on the wake-up signal. All terminal devices in the first wake-up device group correspond to the same wake-up signal reception timing, i.e., the first timing.

[0131] In some embodiments, the first terminal device is one of a plurality of terminal devices. When the plurality of terminal devices are divided into a plurality of wake-up device groups including a first wake-up device group, the plurality of wake-up device groups are divided according to one or more of the following information: wake-up latency of the plurality of terminal devices; ID of the plurality of terminal devices; and number of wake-up device groups of different types in the plurality of wake-up device groups.

[0132] As an example, the wake-up latency of a terminal device, also known as wake-up duration, is used to determine the wake-up time. This wake-up latency also represents the wake-up duration of the second communication module within the terminal device. By assigning terminal devices with different wake-up latencies to different wake-up device groups or subgroups, it is possible to handle terminal devices with different wake-up requirements more efficiently, while minimizing the impact on the false alarm rate.

[0133] As an example, the wake-up latency of a terminal device can include the minimum wake-up latency of the terminal device. The wake-up latency of a terminal device may be multiple parameters, among which the shortest wake-up latency is the minimum wake-up latency. Network devices can group terminal devices based on the minimum wake-up latency of all terminal devices, or they can group them based on the maximum or average wake-up latency of all terminal devices.

[0134] It should be understood that different terminal devices can have different wake-up latencies, primarily due to factors such as hardware characteristics, power optimization strategies, network conditions, and the design goals of the terminal device itself. For example, different terminal devices have different processor speeds, resulting in varying wake-up latencies: high-performance processors may enter an active state faster than low-performance processors. Memory and storage speeds also affect wake-up latency: high-speed memory can speed up recovery from a low-power state. Some terminal devices may employ stricter battery management strategies to extend battery life, potentially leading to longer wake-up latencies. Different terminal devices may support different levels of low-power modes; deeper low-power modes (e.g., longer sleep times) may require more time to wake up. Base stations (eNB or gNB) may configure different wake-up times and DRX cycles for different terminal devices based on network load and coverage. In areas with weak signals, terminal devices may require more time for signal synchronization and recovery, resulting in longer wake-up latencies.

[0135] As one implementation method, network devices can receive wake-up delay reports sent by terminal devices for grouping. Network devices can set multiple wake-up delay value ranges, and terminal devices can determine their wake-up device group based on the corresponding wake-up delay value range.

[0136] As an example, the terminal device ID can be combined with the terminal device's wake-up latency to facilitate grouping terminal devices that have not reported wake-up latency. Exemplarily, wake-up device subgroups formed based on wake-up latency reports occupy a portion of the total number of wake-up device subgroups, with the remaining subgroups used to group other terminal devices. For example, if the total number of wake-up device subgroups is configured to 16, and the number of subgroups assigned to terminal devices with longer wake-up latency is set to 4, then the remaining 12 subgroups can be used to group multiple terminal devices based on their identifiers. Exemplarily, among the terminal devices that reported wake-up latency, those with longer wake-up latency can be assigned to a separate wake-up device subgroup, while those with shorter wake-up latency are grouped together with other devices. In these examples, the number of subgroups of either type can be configured individually.

[0137] As an example, multiple wake-up device groups can be categorized into several different types. These different types of wake-up device groups can include device groups dedicated to terminal devices with longer wake-up latency, or they can include device groups of terminal devices that do not report wake-up latency.

[0138] As an example, multiple wake-up device groups can be grouped based on various information mentioned above. For instance, a network device can assign terminal devices reporting wake-up latency exceeding a specific threshold to a separate wake-up device group. The number of such wake-up device groups can be configured individually by the network, allowing for flexibility in network design and optimization.

[0139] In some embodiments, due to the characteristics of the OOK LP-WUS architecture, the spectral efficiency of LP-WUS is much lower than that of PDCCH. Network devices can also configure multiple wake-up signal (WUS) monitoring times (MOs) for different LOs associated with different wake-up device groups. As an implementation, PEI and / or PO can be associated with MOs, rather than having POs associated with LOs.

[0140] Multiple WUS monitoring times (MOs) can also be configured for different WUS transmission times (LOs) associated with different UE subgroups. Associate the PEI and / or PO with the MO, instead of associating the PO with the LO.

[0141] Referring again to Figure 5, in step S520, the first terminal device performs paging detection at a second opportune moment. The first terminal device can perform this paging detection via a second communication module. For example, the second communication module after wake-up is used to perform paging detection at the second opportune moment. Conversely, the network device can send paging information corresponding to the first terminal device at the second opportune moment or at the corresponding time domain location. The time domain corresponding to the second opportune moment also addresses scenarios with long communication delays. This paging information may include the paging message and / or PEI corresponding to the first terminal device.

[0142] The paging detection performed by the first terminal device can be either directly detecting the paging message at the PO or detecting the PEI used to indicate the PO. Therefore, the second timing can be either detecting the PO of the paging message or detecting the PEI. For example, when LP-WUS and PEI are used together, the second timing can be used to detect the PEI. For example, when LP-WUS and PEI are used together, the second timing can be used to detect the paging message. For example, when the communication system does not use the PEI mechanism, the second timing is used to detect the paging message.

[0143] In some embodiments, when the second timing is used to detect paging messages, the second timing is one of a plurality of POs corresponding to the first terminal device. The first terminal device can determine the location of the PO based on the wake-up delay of the second communication module. In this case, the nearest PO after the wake-up time is selected for monitoring. Based on the determination of the wake-up time, terminal devices monitoring the same LO can identify different POs for paging detection. Furthermore, by supporting terminal devices with different wake-up delays, it is beneficial to locate the POs more accurately.

[0144] In one implementation, the time-domain positions of multiple Page Points (POs) corresponding to the first terminal device can be determined based on the wake-up delay of the first terminal device. The first terminal device can monitor paging messages on the calculated POs to wait for receiving paging messages.

[0145] For example, the position of any PO in the time domain among multiple POs can be determined based on the wake-up delay of the first terminal device and the time domain position of the previous PO. The time domain position of the previous PO can be determined based on the records of the first terminal device or based on system parameters.

[0146] As an example, the wake-up delay remains constant each time the first terminal device performs a paging detection.

[0147] As an example, the wake-up latency of the first terminal device changes each time it performs a paging detection. In order to support terminal devices with different wake-up latencies in effectively monitoring the Page Object (PO) to detect paging messages, the time-domain location of the next PO needs to take into account the change in wake-up latency.

[0148] As one implementation, multiple POs may include a second timing T when the first terminal device is currently performing paging detection. po And the third timing T for the next paging detection next_po The third opportunity T next_po The time-domain location can be represented as:

[0149] T next_po =T wakeup +(T po ―(T wakeup modT po ));

[0150] Among them, T wakeup This indicates the wake-up delay for the first terminal device to perform the next paging detection.

[0151] Optionally, when the first terminal devices have the same wake-up delay, T wakeup Unchanged. The first terminal device can record T after initially receiving the wake-up signal. wakeup Then calculate the time-domain location of the next nearest PO.

[0152] Optionally, when the first terminal devices have different wake-up delays, the first terminal device can determine the wake-up delay T′ based on the current wake-up delay. wakeup and wake-up latency difference Δt wakeup Calculate the adjusted wake-up latency. For example, T wakeup =T′ wakeup +Δt wakeup By calculating the adjusted wake-up latency and dynamically adjusting the monitoring point (PO) time according to different wake-up latency, it can be ensured that each terminal device can monitor the PO at the most appropriate time. This mechanism optimizes the power consumption of terminal devices while efficiently processing paging requests.

[0153] In some embodiments, it may also be beneficial for the first terminal device to monitor other POs besides the relevant PO. For example, if paging load is high, monitoring multiple POs may be helpful. Also, monitoring other POs can prevent POs that need to be monitored from being missed.

[0154] As an example, a network device can configure a window for paging detection for a first terminal device. Within this window, the first terminal device can monitor additional point of sale (PO) for a certain duration after detecting a LO. That is, the first terminal device can perform paging detection at a fourth opportune moment within the first time window. This fourth opportune moment can be a PO unrelated to the first terminal device.

[0155] Optionally, the first time window can be a time window based on LP-WUS reception. This time window has the following characteristics: the first terminal device only monitors existing POs within this time window; the first terminal device switches to sleep mode at the end of the window.

[0156] Optionally, the length of the first time window is determined based on one or more of the following factors: the number of paging requests that the first terminal device is about to make, the number of time slots / frames configured in the system information block (SIB), the cell load, the coverage area of ​​the terminal device, etc.

[0157] Optionally, the network device can determine the specific duration and number of additional POs to be monitored based on the configuration and capabilities of the end devices.

[0158] In some embodiments, the second timing can be determined based on the first wake-up device group. After the first terminal device determines its wake-up device group, it can directly determine the second timing for the first terminal device to perform paging detection based on the association between LO and PO or PO group.

[0159] In some embodiments, the second timing can be determined based on the first paging device group to which the first terminal device belongs or the first PO group to which the first terminal device corresponds. For example, the first terminal device can determine the first timing based on the first wake-up device group it belongs to, and then determine the second timing based on the first paging device group it belongs to or the corresponding first PO group.

[0160] As an example, the first PO group can be the group to which the PO corresponding to the first terminal device belongs. The first PO group is one of multiple PO groups. Multiple PO groups can be grouped according to the time-domain location of multiple POs or the configuration of network devices. For example, multiple POs located within one LO period belong to one PO group. Alternatively, multiple POs located within different LO periods belong to one PO group. Furthermore, the network device can directly configure multiple POs corresponding to a certain terminal device group to form one PO group.

[0161] In some embodiments, the second timing can be determined based on the first wake-up device group and the first paging device group or the first PO group to which the first terminal device belongs, in order to achieve finer sub-grouping granularity of PEI / PO or to divide the terminal devices into subgroups with different terminal device sets. The paging device group can also be called a paging group. Through finer grouping, network devices can more accurately instruct terminal devices to perform paging detection, thus reducing the probability of monitoring the paging PDCCH when not paging.

[0162] All terminal devices in the first paging device group are associated with the same PEI and / or PO. That is, the first paging device group is divided according to the paging configuration of the terminal devices. When all terminal devices in the first paging device group are associated with the same PEI, the division method of the first paging device group is, for example, the division method of the PEI subgroup in NR. When all terminal devices in the first paging device group are associated with the same PO, the division method of the first paging device group can be based on the PO configuration.

[0163] As an example, having all terminal devices associated with the same Pager Point (PO) can be replaced with having all terminal devices associated with the same group of POs. Multiple POs in this group can be configured consecutively or periodically. All terminal devices in the first paging device group will perform paging detection on all POs in that group.

[0164] As an example, when the second timing is determined based on the first wake-up device group and the first PO group, the first terminal device can first determine the LO (first timing) based on the first wake-up device group it belongs to, and then determine one or more POs to perform paging detection in the cycle of that LO based on the first PO group.

[0165] In some embodiments, the terminal devices in the first wake-up device group are partially the same as those in the first paging device group or the first PO group. That is, the division of the first wake-up device group and the first paging device group or the first PO group is independent of each other. Exemplarily, the first wake-up device group and the first paging device group are determined based on different factors. Exemplarily, the first wake-up device group and the first PO group corresponding to the first terminal device are different types of groups.

[0166] Taking PEI-based grouping as an example, multiple wake-up device groups belonging to the first wake-up device group and multiple paging device groups belonging to the first paging device group can be grouped differently based on LP-WUS and PEI, respectively. Multiple wake-up device groups can also be called LP-WUS grouping, and multiple paging device groups can also be called PEI grouping. For ease of understanding, the following uses UE1 to UE9 as examples, showing grouping based on LP-WUS and PEI.

[0167] Referring to the example in Table 1, the terminal device groups based on RAN-based PEI are P1, P2, and P3, while the groups based on LP-WUS are L1, L2, and L3. P1, P2, and P3 are multiple paging device groups including the first paging device group, and L1, L2, and L3 are multiple wake-up device groups including the first wake-up device group. Joint grouping of terminal devices using LP-WUS and PEI nearly doubles the grouping granularity of the terminal devices. When the terminal device supports monitoring the PEI after receiving an LP-WUS wake-up indication, the grouping granularity of the terminal device can be further improved. That is, each LO corresponds to a different wake-up device group, and different wake-up device groups monitor different corresponding LP-WUS LOs.

[0168] Table 1

[0169] As shown in Table 1, UE1 to UE9 can be divided into 6 different subgroups, namely P1={UE1,UE4,UE7}, P2={UE2,UE5,UE8}, P3={UE3,UE6,UE9}, L1={UE1,UE2,UE3}, L2={UE4,UE5,UE6}, and L3={UE7,UE8,UE9}.

[0170] In some embodiments, the terminal devices in the first wake-up device group are all identical to those in the first paging device group. Exemplarily, the same grouping is used for LP-WUS and PEI, as shown in Table 2. That is, the LP-WUS groups L1, L2, and L3 are determined based on the RAN PEI groups P1, P2, and P3. With the same grouping, energy-saving efficiency is further improved. Through joint grouping between LP-WUS and PEI, the terminal devices can monitor the PEI group after receiving a wake-up indication from the LP-WUS group.

[0171] Table 2

[0172] It should be understood that the PEI-based groupings in Tables 1 and 2 can also be replaced with PO-based groupings. For example, when the system does not use PEI, the first paging device group to which the first terminal device belongs can be determined based on the relevant information of the PO associated with the first terminal device.

[0173] The above sections, in conjunction with Tables 1 and 2, introduced various methods for splitting joint packets based on LP-WUS and PEI. Joint paging based on LP-WUS and PEI helps to further reduce the probability that the network instructs terminal devices to monitor the paging PDCCH when not paging. The following sections, in conjunction with Figures 7 to 9, provide an exemplary illustration of the method for terminal devices to perform paging detection based on this joint packet. Each LP-WUS in Figures 7 to 9 supports one LO. The PO group associated with an LO can be the PO within the period of the LO. Here, the first terminal device is UE1, and the first timing corresponding to the first wake-up signal is LO1. The first communication module in the first terminal device is LR, used to receive LP-WUS; the second communication module is MR, used to detect PEI and / or detect paging messages on PO. The LP-WUS-based and PEI-based packets are different in Figure 7, while the LP-WUS-based and PEI-based packets are the same in Figures 8 and 9.

[0174] Referring to Figure 7, LO1 is only used by terminal devices in the L1 group to monitor LP-WUS. Other terminal devices, even if paging occurs, must wait for LO2 or another LO group to monitor WUS, thus increasing the probability of PEI monitoring. For example, UE4, UE5, and UE6 can monitor WUS in LO2, while UE7, UE8, and UE9 must wait for LO3. When LO and PEI groups are handled separately, the overlap of the two groups allows for more accurate detection indication.

[0175] As shown in Figure 7, terminal devices UE1, UE2, and UE3 in group L1 can all receive the PEI and determine the subsequent PO within the period of LO1. Furthermore, UE1 can detect the paging message based on the first PO after the PEI in its P1 group, UE2 can detect the paging message based on the second PO after the PEI in its P2 group, and so on.

[0176] Referring to Figure 8, when LO grouping and PEI / PO grouping are performed separately, and both groups are identical, more precise instructions are given only based on users in a specific terminal device group. As shown in Figure 8, terminal devices UE1, UE2, and UE3 belonging to the L1 / P1 group can receive the PEI and determine the subsequent PO instruction in the LO1 cycle. The remaining terminal device groups can continue to detect PEI or paging messages in subsequent LO cycles. For example, if one LP-WUS corresponds to multiple LOs or multiple MOs, the remaining LOs or MOs in this cycle can be used to receive paging instructions, that is, PEI and MO can be matched one-to-one.

[0177] As shown in Figure 8, terminal devices UE1, UE2, and UE3 in group L1 can detect paging messages on the first PO after PEI in the LO1 cycle of their respective P1 group. Terminal devices UE4, UE5, and UE6 in group L2 can detect paging messages on the second PO after PEI in the LO2 cycle of their respective P2 group, and so on.

[0178] Comparing Figures 8 and 9, it can be seen that the PEI in Figure 9 only appears within the cycle of LO1; subsequent consecutive cycles only contain PO (without PEI). In scenarios where the PEI remains constant or the PEI change time is longer than the LO cycle, the paging device group that receives subsequent PEI indications or the PO group associated with the first LO can receive them within the first LO cycle. Other paging device groups or PO groups associated with other LOs can detect POs in subsequent LO cycles without needing to read PEI information again.

[0179] As one implementation shown in Figure 9, since the wake-up device group and the paging device group are grouped in the same way, the terminal device can determine its paging device group after determining the wake-up device group, thereby determining the PO for paging detection. As shown in Figure 9, after receiving the wake-up signal at LO2, the terminal devices UE4, UE5, and UE6 in the L2 group do not need to read the PEI information. These terminal devices can determine that they belong to the P2 group based on the L2 group, and thus detect the paging message on the second PO within the LO2 cycle, and so on.

[0180] The preceding sections, with reference to Figures 5 to 9, introduced a method for more refined indication of paging detection based on joint grouping. In this method, joint grouping based on LP-WUS and PEI can reduce the false detection rate of paging messages by the terminal device while achieving energy savings. As shown in Figure 9, in scenarios using the PEI mechanism, the terminal device does not necessarily need to detect PEI after receiving LP-WUS. In the embodiments of this application, the first terminal device can determine whether to listen for PEI based on various factors.

[0181] In some embodiments, the first terminal device may determine whether to listen to the PEI corresponding to the first terminal device based on the wake-up delay of the second communication module. The PEI corresponding to the first terminal device corresponds to one or more reception times (i.e., LO) of the first wake-up signal. For example, if the wake-up delay of the second communication module is long, the PEI will arrive before the wake-up, and listening to that PEI may not be necessary.

[0182] As an example, after receiving the first wake-up signal at the first opportune moment, the first terminal device can determine whether to wake up the second communication module based on its wake-up delay. In some scenarios, waking up the second communication module can replace listening to the PEI corresponding to the first terminal device. In other scenarios, waking up the second communication module can replace listening to the paging message corresponding to the first terminal device on the PO.

[0183] As an example, the time interval between the LO (first timing) and MR (second communication module) wake-up can be used to control whether the terminal device is allowed to monitor the PEI. If the first terminal device needs to monitor the PEI after receiving the LP-WUS indicating wake-up, this time interval should not be less than the minimum time interval for the first terminal device to wake up the MR. That is, if the time interval between the LO and the PEI is not greater than the minimum wake-up delay in the first terminal device's capability report, then monitoring the PEI is not required after receiving the LP-WUS indicating wake-up.

[0184] As an example, the first timing point can be the first time the first terminal device receives LP-WUS. When the time interval between the first timing point and the PEI corresponding to the first terminal device is greater than the minimum wake-up delay of the second communication module, the first terminal device listens to that PEI. Alternatively, when the time interval between the first timing point and the PEI corresponding to the first terminal device is less than or equal to the minimum wake-up delay of the second communication module, the first terminal device does not listen to that PEI.

[0185] In some embodiments, the first terminal device can determine whether to listen to the PEI corresponding to the first terminal device based on the position of the first wake-up time among multiple wake-up time periods. As shown in FIG9, when the first wake-up device group is one of multiple wake-up device groups (L1 to L3), the multiple wake-up device groups correspond to multiple wake-up time periods respectively. After receiving the first wake-up signal at the first wake-up time, the first terminal device can determine whether to listen to the PEI corresponding to the first terminal device based on the position of the first wake-up time among multiple wake-up time periods. For example, if the first wake-up time is LO1 in FIG9, the first terminal device needs to listen to the PEI; if the first wake-up time is LO2 or LO3 in FIG9, the first terminal device does not need to listen to the PEI.

[0186] As an example, when the first timing is the first of a plurality of timings, the first terminal device listens to the PEI corresponding to the first terminal device. Alternatively, when the first timing is any of the plurality of timings other than the first timing, the first terminal device does not listen to the PEI corresponding to the first terminal device.

[0187] In some embodiments, the first terminal device listening to its corresponding PEI can be replaced by the second communication module listening to the PEI corresponding to the first terminal device. That is, when it is necessary to listen to the PEI, the second communication module has been activated.

[0188] In some embodiments, the first terminal device listening to its corresponding PEI can be replaced by the first communication module listening to the PEI corresponding to the first terminal device. That is, when it is necessary to listen to the PEI, the second communication module does not need to be woken up. Instead, it is woken up only when it is necessary to monitor the PO.

[0189] As mentioned above, network devices group terminal devices based on their wake-up delay reports. Therefore, the first terminal device needs to report its wake-up delay information to the network device so that the network device can determine the wake-up device group to which the first terminal device belongs based on the wake-up delay. In other words, the network device can effectively group the first terminal device using wake-up delay information reported by multiple terminal devices.

[0190] In some embodiments, the first terminal device can report its wake-up latency information to the network device through capability reporting. For example, the first terminal device can send its capability information to the network device. The capability information reported by the first terminal device can be used to indicate the minimum wake-up latency of the second communication module. The minimum wake-up latency can represent the wake-up-related capabilities of the first terminal device.

[0191] As an example, the capability information reported by the first terminal device can directly include the minimum wake-up latency of the second communication module.

[0192] As an example, the first terminal device can report whether it supports the LP-WUS function. For instance, the network device can specify a reference value for the wake-up latency, and terminal devices that support the LP-WUS function can achieve a wake-up latency equal to or less than this reference value.

[0193] As an example, the first terminal device can report one (e.g., 2, 3, 4, etc.) or multiple (e.g., a combination of multiple integers) wake-up delay values ​​from M candidate values ​​via capability reporting. The minimum wake-up delay can be the minimum interval between the first communication module performing LP-WUS reception and the second communication module (MR) starting PDCCH monitoring.

[0194] As one embodiment of the above example, the first terminal device can select the minimum wake-up delay from M candidate values ​​according to actual communication needs, and report it to the network device through a capability report. Each of the M candidate values ​​can represent the wake-up delay of the first terminal device.

[0195] As one embodiment of the above example, the first terminal device can report M candidate values ​​through the capability report, and the network device selects one value from the M candidate values ​​according to the configuration of the PO, and instructs the first terminal device through the first wake-up signal.

[0196] Optionally, the capability information reported by the first terminal device may also include an offset reference between LO and PO. The offset value between LO and PO can be configured by the network device. The network device can correctly determine the individual offset between the LO and PO corresponding to the first terminal device based on the capability report of the first terminal device.

[0197] As an example, when the single offset is configured by the network device, this parameter depends on the first terminal device's ability to monitor LP-WUS. If the first terminal device has sufficient time to monitor LP-WUS, it can monitor paging messages on the PO based on the LP-WUS and the indication of the single offset to save power. If the first terminal device does not have sufficient time to be woken up, it can monitor paging messages on the PO as a legacy behavior.

[0198] As an example, in the capability information reported by the first terminal device, the first terminal device can report a minimum time offset value for each subcarrier spacing (SCS). For example, different SCSs can have different minimum time offset values. The network device can configure an offset value based on the capability information reported by the first terminal device.

[0199] As an example, in RRC idle / inactive mode, it is possible to support the wake-up of terminal devices with different MR ramp rise times and different sleep states. For example, the time offset value configured in the network device can ensure that a terminal device with a longer ramp rise time can be woken up after the minimum time offset, so that a terminal device with a shorter rise time can also open its MR within that minimum time offset.

[0200] As mentioned earlier, the first information can be carried in various ways. Taking the symbols generated by LP-WUS OOK as an example, the first information can be designed using two methods: bitmaps and code point values. In other words, the first information can indicate whether the second communication module has been woken up using either a bitmap or code point values. The following section will use the LP-WUS design as an example to illustrate this.

[0201] In some embodiments, for bitmap-based LP-WUS, a single bit can indicate whether the second communication module needs to be woken up by the first terminal device or all terminal devices in a device subgroup. Exemplarily, in an N-bit bitmap sequence, each bit can represent the wake-up state of a terminal device subgroup. As one implementation, by initializing the bitmap, a bitmap of length N with an initial state of all 0s (or all 1s) can be generated to indicate that none of the terminal devices need to be woken up. The bits at corresponding positions are set to 1 (or 0) according to the list of terminal devices to be woken up. Each terminal device subgroup is assigned a unique identifier (ID) ranging from 0 to N-1. After receiving the bitmap signal within a specified time window, the first terminal device can decode the bitmap based on its own ID. If the bit at the corresponding position is 1 (or 0), the first terminal device can enter the wake-up state.

[0202] For N-bit bitmap-based LP-WUS, whether the first terminal device needs to wake up is determined solely by the bits associated with its subgroup, regardless of the values ​​of the other N-1 bits. However, to detect a single bit associated with its subgroup, the first communication module also needs to detect the other N-1 bits. If any of the other N-1 bits is not detected correctly, the cyclic redundancy check (CRC) will fail, and LP-WUS will delete the entire bitmap. This is the main reason why bitmap-based LP-WUS may have a higher false negative rate.

[0203] In some embodiments, the code point-based LP-WUS can be used to indicate information about at least a certain number of device subgroups. Exemplarily, all the information carried by the LP-WUS can be used to determine whether a first terminal device or a second communication module needs to be woken up. The code point-based LP-WUS can be implemented by sequence selection or encoded bit blocks. In generating the code point-based LP-WUS using CRC bit blocks, the subgroup ID of the first terminal device is first mapped to a bit block in an encoded sequence or binary number of that subgroup index. Then, a polynomial CRC sequence, i.e., each row of the matrix, is applied to generate the OOK symbol of the LP-WUS. The generated sequence may not have the same good autocorrelation / cross-correlation properties as Gold, M, or Walsh sequences.

[0204] As an example, the encoding method can be any of the following: one-hot encoding, binary encoding, Gray code, Huffman encoding, waveform coding, differential coding, etc. The specific encoding method chosen depends on the application requirements and environmental conditions. Combining CRC with LP-WUS generation based on code point values ​​can effectively improve the reliability and accuracy of the wake-up signal.

[0205] As an example, one-hot encoding combined with CRC is used to generate LP-WUS based on code point values. Taking the subgroup IDs and corresponding one-hot codes in Table 3 as an example, only one bit in the encoding has a value of 1, and the rest have values ​​of 0. As shown in Table 1, assuming there are 8 subgroup IDs (0 to 7) in Table 3, each subgroup ID is represented by an 8-bit vector. Only the bit at the corresponding subgroup ID position is 1, and all other bits are 0. The CRC bit is a check bit calculated based on the original data, used to ensure that no errors occur during data transmission. In use, the one-hot encoded data is appended with the corresponding CRC check bit. The one-hot encoding and the calculated CRC bit are combined to form the final bit block, and the base station transmits these generated bit blocks through the control channel.

[0206] Table 3

[0207] As an example, binary encoding is used, such as having 8 subgroup IDs (0 to 7), with each subgroup ID represented by 3 bits of binary.

[0208] As an example, using Gray code, each subgroup ID is represented by a 3-bit Gray code.

[0209] As an example, Manchester encoding is used in a sequence-based (or bitmap-based) LP-WUS design. Manchester decoding is performed bit-by-bit. Specifically, the second communication module first calculates two energy values ​​based on the first and second halves of the received Manchester-encoded OOK symbol, using the left half energy (E... a Subtract the energy on the right (E) bThe power increment per bit is obtained by using a two-stage LP-WUS detection process. The absolute value of this power increment is essentially the reference signal received power (RSRP). Then, detection or comparison is performed to determine whether the received waveform contains a valid wake-up signal or a sequence associated with the first terminal device or its subgroup. Through this two-stage LP-WUS detection process, Manchester encoding does not affect the properties of the underlying WUS sequence.

[0210] Comparing bitmap-based and code point-value-based designs, the main difference lies in whether LP-WUS includes interference information unrelated to the wake-up information of the first terminal device. Taking Manchester encoding as an example, for bitmap-based LP-WUS, it is difficult to detect the symbol of each bit energy increment as 1 or 0, requiring CRC verification of the entire LP-WUS hard-detected 0 / 1 bit sequence. For sequence-based LP-WUS, each bit increment energy value of the entire sequence is associated with the target sequence associated with the first terminal device, and the correlation result is compared with the sequence detection threshold.
