[0045] 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 also include at least some of the following contents.

[0046] 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.

[0047] To reduce the power consumption of terminal devices, some communication systems have introduced low-power wake-up modules and LP-WUS. LP-WUS can be simply referred to as a wake-up signal (WUS). The low-power wake-up module is also called a low-power wake-up receiver (LP-WUR). For example, when the terminal device is idle, it can turn off the main communication module / main receiver (MR) or put it into deep sleep mode, and only listen for LP-WUS through the LP-WUR, thereby reducing the power consumption of the terminal device. Compared to MR, LP-WUR can also be simply referred to as a low-power receiver (LR). When the MR is woken up, the terminal device can enter the radio resource control (RRC) connected state.

[0048] As an example, to reduce the power consumption of terminal devices due to periodic paging message checks, the NR system introduced LP-WUS.

[0049] The LP-WUR of a terminal device can be continuously activated to receive LP-WUS. Therefore, LP-WUR can operate independently of the 5G device; that is, the 5G device can be deactivated while LP-WUR is active and searching for potential LP-WUS. In some scenarios, the time when a terminal device listens for LP-WUS may overlap with the monitoring period of the reduced-power physical downlink control channel (PDCCH). When multiple terminal devices simultaneously listen for LP-WUS, false wake-ups may occur. To ensure the low-power performance of the terminal device, it is necessary to consider how to embed LP-WUS into the relevant communication system (e.g., NR system).

[0050] LP-WUR can support one or more modulation / multiple access methods. An LP-WUR can replace a specific modulation method with an LP-WUR based on that modulation method. For example, an LP-WUR can only support orthogonal frequency division multiplexing (OFDM). Another example is that an LP-WUR can only support on-off keying (OOK). Yet another example is that an LP-WUR can support both OFDM and OOK. OOK modulation allows the receiver to achieve low-power envelope / energy detection. OOK is also a special case of amplitude shift keying (ASK). OOK has only two amplitudes, ON and OFF.

[0051] In some embodiments, the LP-WUR of the terminal device can be classified into different types based on the supported modulation schemes. For example, when the LP-WUR only supports OFDM, the LP-WUR type is an OFDM-only receiver type. This type of receiver can obtain wake-up information from the superimposed OFDM symbols. As another example, when the LP-WUR only supports OOK, the LP-WUR type is an OOK-only receiver type. Furthermore, when the LP-WUR supports both OFDM and OOK, the LP-WUR type is a receiver type based on both OFDM and OOK.

[0052] Communication systems can support terminal devices with low-power receiver types. For example, NR systems can support different LP-WUS types. Since NR systems are based on OFDM transmission, they can support only OFDM-based receiver types, or they can support both OFDM-based and OOK-based receiver types. Taking the NR system as an example again, when the NR system only supports OFDM-based receiver types, LP-WUS transmission in the system is only for OFDM-based receivers; this can be referred to as Case A. When the NR system supports both OFDM-based and OOK-based receiver types, LP-WUS transmission in the system is for both OFDM-based and OOK-based receivers; this can be referred to as Case B. Therefore, LP-WUS transmission has two scenarios, and network devices can switch between Case A and Case B depending on the type of the target WUR.

[0053] In case A, the network device determines the complete information bits configured for the OFDM-based receiver and sends LP-WUS for a duration determined by the number of OFDM symbols X required to transmit the complete information bits, where X is a positive integer.

[0054] In case B, the network device determines the complete information bits for the OOK-based receiver configuration and transmits LP-WUS for a duration determined by the number of OFDM symbols Y required to transmit the complete information bits, where Y is a positive integer.

[0055] Assuming the information bits of WUS are carried by overlapping OFDM sequences, the duration of WUS may be short in both case A and case B. However, the duration of WUS may differ between OFDM and OOK receivers.

[0056] As an example, a network device (e.g., a gNB) can enable LP-WUS functionality for terminal devices in a cell that have an LP-WUS type. In an NR system, the network device may only serve OFDM-based receivers. The information the network device can provide differs for terminal devices in different RRC states. For example, for IDLE / INACTIVE mode, the network device can send LP-WUS for OFDM-based receivers only. Similarly, for CONNECTED RRC mode, the network device can provide LP-WUS configuration for OFDM-based receivers only.

[0057] In the example above, the LP-WUS configuration can include conditions for the receiver to enter / exit the LP-WUS listening state.

[0058] As another example, network devices can enable LP-WUS functionality for terminal devices in a cell that have two LP-WUR types. In case A, for terminal devices in idle / inactive mode, LP-WUS transmissions within a given time period will only page OFDM-based receivers. In case B, for terminal devices in connected mode, the network device configures LP-WUS separately for OFDM-based and OOK-based receivers. For example, the network device can use different WUS monitor occasions (MO) and / or different codepoints to configure LP-WUS for different receivers.

[0059] In the example above, when LP-WUS is only for OFDM-based receivers, the duration of LP-WUS transmission can be determined by the unchannel-coded information bits, the number of overlapping OFDM sequences per OOK ON chip, and the repetition factor, without depending on the OOK ON-OFF mode for OOK receivers.

[0060] The above section described scenarios where network devices transmit WUS based on different conditions. When a communication system includes multiple types of LP-WUS, it is unknown to the terminal device whether the network device performs LP-WUS transmission based on condition A or condition B. For example, for an idle / inactive terminal device, the network device may not need to indicate which condition is used for WUS transmission. Similarly, when the network device performs block-level repetition of overlaid OFDM sequences over Y symbols based on condition B, the terminal device may not know the duration of the LP-WUS.

[0061] Since network devices may switch between LP-WUS transmission modes, how terminal devices should receive LP-WUS signals is a problem that needs to be considered.

[0062] Furthermore, different types of LP-WURs can receive different synchronization signals. Some receiver types can receive traditional synchronization signal blocks (SSBs), namely the primary synchronization signal (PSS) and secondary synchronization signal (SSS). For terminal devices with these types of receivers, traditional PSS / SSS can be used for synchronization and radio resource management (RRM). However, other types of receivers cannot receive traditional PSS / SSS. For terminal devices with these types of receivers, low-power synchronization signals (LP-SS) are required to complete synchronization and RRM. LP-SS can be transmitted based on OOK-1 and / or OOK-4 waveforms with or without superimposed OFDM sequences. Therefore, when a communication system includes multiple different types of LP-WURs, how network devices configure the transmission of synchronization signals is also a consideration.

[0063] It should be understood that SSB in the embodiments of this application also represents the synchronization signal / physical broadcast channel block (SS / PBCH block).

[0064] 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 based on configuration information to determine whether it has been woken up. This configuration information is related to the modulation scheme supported by the low-power receiver of the terminal device (i.e., the type of the terminal device); that is, different receiver types correspond to different configuration information. Therefore, network devices can send different configuration information based on the type of low-power receiver possessed by the terminal device, which not only facilitates the terminal device in receiving the wake-up signal according to its own receiver type but also reduces the transmission overhead of the wake-up signal.

[0065] To facilitate understanding, the following will be combined with... Figure 2 The methods proposed in the embodiments of this application will be described in detail. Figure 2 It is presented from the perspective of the interaction between terminal devices and network devices.

[0066] The terminal device can be any type of communication terminal capable of receiving a wake-up signal, and is not limited thereto. The terminal device can determine whether it has been woken up by receiving a wake-up signal. In some embodiments, the terminal device can be in an idle state or an inactive state. For example, the terminal device can be a UE in RRC idle (RRC_IDLE) / RRC inactive (RRC_INACTIVE) mode.

[0067] As an example, when determining whether to wake up based on the wake-up signal, the terminal device will have a certain wake-up delay. The wake-up delay of the terminal device is related to the transmission period of the synchronization signal. Taking the SSB period (SSBperiodicity) as an example, the wake-up delay of the terminal device can be defined as the three UE capabilities shown in Table 1.

[0068] Table 1

[0069]

[0070] In some embodiments, the 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.

[0071] The terminal device may include a first communication module and a second communication module. For example, the terminal device may include two independent communication modules to save power. The first and second communication modules in the terminal device may be integrated together, but the operating state and / or shutdown state of the two communication modules can be set separately. The first and second communication modules may be in different states. For example, when the second communication module is in the shutdown state, the first communication module may be in an active state of searching for wake-up signals.

[0072] In some embodiments, the first communication module and the second communication module perform different functions to reduce the power consumption of the terminal device. The first communication module receives a first wake-up signal for waking up the second communication module, which then performs paging detection.

[0073] 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 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.

[0074] The terminal device includes a low-power receiver for receiving signals in a low-power state. The low-power receiver may be a first communication module, or may include a first communication module. The low-power receiver may be an LP-WUR or a receiver with similar functionality to an LP-WUR.

[0075] As an example, the low-power receiver included in the terminal device can be replaced with an LP-WUR and monitoring of the LP-WUS can be implemented.

[0076] As an example, a terminal device may include one or more low-power receivers. When a terminal device includes multiple low-power receivers, the types of the multiple low-power receivers may be the same or different, and this is not limited here.

[0077] Terminal devices can be classified based on the modulation schemes supported by low-power receivers. Modulation schemes can be replaced with waveforms. For ease of classification and explanation, OFDM in the following text can be replaced with OFDM waveforms, or OFDM modulation. It should be noted that OFDM modulation differs from binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), and quadrature amplitude modulation (QAM).

[0078] Low-power receivers in different terminal devices can support multiple modulation schemes or multiple waveforms. For example, a low-power receiver can support either a first modulation scheme or a second modulation scheme. Or, a low-power receiver can support either a first waveform or a second waveform.

[0079] Taking the waveform / modulation method including the first modulation method and the second modulation method as an example, when the low-power receiver of the terminal device only supports the first modulation method, the terminal device is a first type of terminal device; when the low-power receiver of the terminal device only supports the second modulation method, or supports both the first and second modulation methods, the terminal device is a second type of terminal device.

[0080] As one embodiment, the first modulation scheme is OFDM, and the second modulation scheme is OOK. Alternatively, the first waveform is an OFDM waveform, and the second waveform is an OOK waveform. When the terminal device is a type 1 terminal device, the low-power receiver included in the terminal device only supports OFDM; when the terminal device is a type 2 terminal device, the low-power receiver included in the terminal device supports both OFDM and OOK, or only OOK. A low-power receiver that only supports OFDM is an OFDM-based receiver. A low-power receiver that only supports OOK is an OOK-based receiver. A low-power receiver that supports both OFDM and OOK is a hybrid receiver based on both OFDM and OOK.

[0081] As another embodiment, the first modulation / waveform mode is OFDM, and the second modulation mode is a modulation mode different from OFDM and OOK.

[0082] As an example, for the same wake-up signal, the time-frequency resources occupied by the first modulation scheme are smaller than those occupied by the second modulation scheme. For instance, for the same wake-up signal, the number of OFDM symbols occupied by the first modulation scheme is smaller than the number of OFDM symbols occupied by the second modulation scheme.

[0083] 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.

[0084] 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 to wake up a terminal device in a low-power state. For example, the network device may send configuration information to the terminal device to instruct the terminal device to receive LP-WUS. This configuration information may support different types of low-power receivers. For example, the network device may send SSB or LP-SS to facilitate synchronization of the terminal device. For example, the network device may send a paging message.

[0085] As an example, LP-WUS transmissions performed by network devices can be switched between Case A and Case B as described above. For instance, when terminal devices in a cell have different types of LP-WUS, the network device can transmit LP-WUS on all 32 OFDM symbols (Case B) to support terminal devices in the cell with OOK-based LP-WUS. However, when the network device does not have sufficient resources to support OOK-based LP-WUS, the handover between Case A and Case B can be achieved by enabling LP-WUS operation under Case A only for terminal devices with OFDM-based LP-WUS.

[0086] 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.

[0087] 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.

[0088] See Figure 2 In step S210, the terminal device receives a first wake-up signal sent by the network device. The first wake-up signal can be the LP-WUS mentioned above or a signal with similar functionality to LP-WUS. The wake-up signal can also be called a wake-up sequence.

[0089] As an example, the first wake-up signal can be repeatedly transmitted based on a repetition factor K, where K is a positive integer. The terminal device can receive at least one of the K first wake-up signals. For example, the transmission of the first wake-up signal can begin from the first MO in the wake-up signal transmission cycle, and multiple first wake-up signals can be transmitted using consecutive MOs.

[0090] As an example, the terminal device receives the first wake-up signal on the transmission resource of the first wake-up signal. The transmission resource of the first wake-up signal is the monitoring time (MO) of the first wake-up signal. The terminal device can receive or detect the wake-up signal on the MO to determine whether it has been woken up. For example, the terminal device can monitor and / or detect the first wake-up signal on one or more candidate MOs. The MO of the wake-up signal can also be referred to as the monitoring time or monitoring moment of the wake-up signal.

[0091] Terminal devices receive wake-up signals via low-power receivers. Wake-up signals can also be classified based on the modulation schemes supported by the low-power receiver. For example, when the terminal device's low-power receiver only supports the first modulation scheme, the wake-up signal corresponding to the terminal device belongs to the first type of wake-up signal; when the terminal device's low-power receiver only supports the second modulation scheme, or supports both the first and second modulation schemes, the wake-up signal corresponding to the terminal device is a second type of wake-up signal.

[0092] As an example, based on different modulation schemes, the time-frequency resources occupied by the first type of wake-up signal are smaller than those occupied by the second type of wake-up signal. For instance, the number of OFDM symbols occupied by the first type of wake-up signal is less than that occupied by the second type of wake-up signal. Therefore, when sending the same wake-up information, the transmission overhead of the first type of wake-up signal is relatively smaller.

[0093] As an example, a Type I wake-up signal can be used for a Type I terminal device with an LP-WUR that only supports OFDM. The Type I wake-up signal is modulated based on OFDM. It is transmitted by transmitting a superimposed OFDM sequence.

[0094] In the example above, the first wake-up signal can be repeatedly transmitted based on superimposed (overlapping) OFDM sequences. When repeating transmissions, the network device can configure a specific number of repetitions (i.e., a repetition factor). The repetition mode of the first wake-up signal includes one of the following: repeating the set of all overlapping OFDM sequences for a code point; repeating each overlapping OFDM sequence in the set of overlapping OFDM sequences.

[0095] As an example, the second type of wake-up signal can be used for a second type of terminal device with LP-WUR that supports both OFDM and OOK. The modulation of the second type of wake-up signal accommodates both OFDM and OOK methods.

[0096] As an example, the MO that monitors the wake-up signal can transmit the wake-up signal via one or more OOK chips.

[0097] The first wake-up signal can be any one or more signals received by the terminal device for waking up the terminal device. The first wake-up signal received by the terminal device can be a first-type wake-up signal or a second-type wake-up signal. For example, the first wake-up signal can be LP-WUS for an OFDM-based receiver, i.e., a first-type wake-up signal. As another example, the first wake-up signal can be LP-WUS for both OFDM-based and OOK-based receivers, i.e., a second-type wake-up signal.

[0098] As an example, when the first wake-up signal is for an OFDM-based LP-WUR, it allows for a shorter LP-WUS transmission duration. For network devices, the shorter duration reduces LP-WUS overhead. For terminal devices with an OFDM-based LP-WUR, energy saving can be achieved through early termination (early stop). Taking a first wake-up signal with a code block length of 32 as an example, after applying Manchester encoding, the number of OFDM symbols required for the network device to transmit the first wake-up signal is 32. In this case, an OOK-based LP-WUR must monitor all OFDM symbols to obtain wake-up information. However, for an OFDM-based LP-WUR, wake-up information can be obtained and LP-WUS monitoring can be terminated after monitoring only 2-3 OFDM symbols. Even if two superimposed OFDM sequences are received to improve reception performance, the terminal device can still determine the wake-up status by monitoring only 4-6 OFDM symbols.

[0099] The terminal device receives a first wake-up signal based on configuration information. This configuration information relates to the modulation scheme supported by the low-power receiver receiving the wake-up signal. Alternatively, it can be related to the type of the first wake-up signal, the type of the terminal device, or the type of the low-power receiver. For example, different types of wake-up signals can be configured with different configuration information. Furthermore, different types of terminal devices may correspond to different configuration information.

[0100] In some embodiments, the configuration information is either first configuration information or second configuration information. The first configuration information is used to configure parameters for a first type of wake-up signal for a first type of terminal device. The second configuration information is used to configure parameters for a second type of wake-up signal for a second type of terminal device. As mentioned above, the low-power receiver of the first type of terminal device only supports the first modulation scheme. The low-power receiver of the second type of terminal device supports both the first and second modulation schemes, or only the second modulation scheme.

[0101] Terminal devices can determine configuration information in various ways. In some embodiments, the configuration information can be determined based on predefined or pre-configured information. In some embodiments, the terminal device can receive configuration information sent by a network device. This configuration information can be sent via semi-static configuration or via dynamic configuration. The configuration information can be carried in at least one of the following: RRC signaling; system information block (SIB); dedicated parameters; first synchronization signal.

[0102] In some embodiments, configuration information can be determined through predefined or preconfigured information. This preconfiguration information can be implicitly indicated through configuration parameters related to LP-WUS, without the need for additional RRC signaling. For example, the terminal device can determine the LP-WUR type corresponding to the first wake-up signal by listening to the MO of the wake-up signal, the code point associated with the wake-up signal, or a combination of both. That is, based on the rules preconfigured by the protocol, the terminal device can determine the LP-WUR type corresponding to the configuration information based on the MO and / or code point.

[0103] As an implementation approach, MOs can be divided into two categories: OFDM-only MOs and mixed MOs that support both OFDM and other modulations. Configuration information can indicate the indices for different MO types. For example, a network device can configure an "OFDM-only MO" with index A ∈ {0, 2, 4} and a "mixed MO" with index B ∈ {1, 3, 5}.

[0104] As another implementation, the code point parameter can be carried in the header field of the corresponding LP-WUS sequence, so that the terminal device can determine the supported receiver type based on the parameter. For example, the code point parameter that only supports OFDM is codepointForOfdmOnly; the code point parameter that supports OFDM and other modulation mixtures is codepointForMixed.

[0105] In some embodiments, the terminal device can receive configuration information from the network device in idle / inactive mode. This configuration information can be carried in a first synchronization signal. That is, the terminal device can receive a first synchronization signal sent by the network device. In addition to synchronization, the first synchronization signal can also carry configuration information for a wake-up signal. When the terminal device is a first type of terminal device, the first synchronization signal is an SSB; when the terminal device is a second type of terminal device, the first synchronization signal includes LP-SS. For example, a terminal device with an OFDM-based LP-WUR supports SSB-based RRM measurement and can use SSB for synchronization. As another example, LP-SS is used for an OOK-based LP-WUR.

[0106] As an example, the first synchronization signal may carry configuration information of the first wake-up signal so that the terminal device can receive the wake-up signal.

[0107] In some embodiments, the terminal device can receive configuration information from the network device in RRC connection mode. For example, the configuration information can be carried in RRC signaling, broadcast information, or dedicated parameters.

[0108] As an example, network devices can broadcast this configuration information via an SIB. An SIB is at least one SIB associated with LP-WUS.

[0109] As an example, network devices can send first or second configuration information via RRC signaling. RRC can send configuration information to terminal devices based on new parameters. For instance, RRC signaling can indicate wake-up signal configuration information based on a first information element (IE). The first IE can include one or more of the following parameters: numMO, offsetMO, numMOperPeriodicity, LP-WUS_num_overlaidSeq_CONNECTED, WUS-PDCCHMonitoringTimer, WUS_available_slot_IDLE / INACTIVE, and WUS_available_symbol_IDLE / INACTIVE.

[0110] Optionally, the first IE may also include the parameter MOPeriodicity. Additionally, the parameter offsetMO may also be represented as MOoffset.

[0111] Optionally, the parameter MOPeriodicity can be used to indicate the LP-WUS cycle. Network devices can be configured with two LP-WUS cycle cycles, for example, a long LP-WUS cycle and a short LP-WUS cycle. In this case, the MOPeriodicity parameter does not need to be a fixed value. The system can also support switching between long and short LP-WUS cycles. This switching design can be the same as the connected-discontinuous reception (C-DRX) mechanism, including medium access control (MAC) control element (CE) control and timing control. As an example, the network device can determine the LP-WUS monitoring timing (MO) based on any one LP-WUS cycle. As another example, the network device can be configured to use which LP-WUS cycle based on the current service scenario. Terminal devices can send auxiliary information to the network device to indicate whether to disable the LP-WUS function or whether the LP-WUS function can be re-enabled.

[0112] In the example above, the first IE is WUS-MOCONNECTED. The terminal device can be provided with parameters relative to the system frame with system frame number (SFN) 0 by WUS-MOCONNECTED. The first IE can indicate the periodicity of the MO starting from SFN0, the time offset of the periodic MO, so that the terminal device can determine the candidate MO for the first wake-up signal.

[0113] In the example above, the new RRC parameter can also instruct the terminal device to terminate the LP-WUS detection of overlapping OFDM sequences in advance, which will be explained in conjunction with Table 2 below.

[0114] Optionally, the serving cell where the terminal device resides can indicate the MO (Motion Occurrence) using a bitmap to facilitate WUS (Warehouse United States) detection by the terminal device. For example, each cell on the primary cell (Pcell) / primary secondary cell (PScell) can provide a bitmap to the terminal device via the parameter WUS_available_slot_IDLE / INACTIVE configured in RRC signaling. This bitmap corresponds to a set of continuously repeating time units and indicates the subset of time units available for the terminal device to monitor WUS within that set. A time unit can include one to four time slots. A set of time units can be {10, 20, or 40} time units. The first symbol of a set of time units every 40 milliseconds / P period is the first symbol in the frame number mod4 = 0, where P is the duration of the set of time units in milliseconds. Furthermore, the parameter WUS_available_symbol_IDLE / INACTIVE can also provide the terminal device with an indication of the symbol within each time unit of the subset of time units for WUS monitoring.

[0115] Optionally, if WUS_available_slot_IDLE / INACTIVE is not provided to the terminal device, the terminal device may assume that all time units are available for monitoring WUS. If WUS_available_symbol_IDLE / INACTIVE is not provided to the terminal device, the terminal device may assume that all symbols in the time unit used for monitoring WUS by the terminal device are available for monitoring WUS. The terminal device may assume that a symbol is not available for monitoring WUS when the following occurs:

[0116] This symbol is represented as uplink common by the time division duplex (TDD) UL DL configuration;

[0117] This symbol, represented by ssb-PositionsInBurst in SIB1, is used for SS / PBCH block transmission, and SS / PBCH block transmission will overlap with WUS transmission in frequency.

[0118] The symbol PDCCH-ConfigSIB1 represents PDCCH transmission, and the control resource set (CORESET) 0 of PDCCH transmission will overlap with WUS transmission in frequency.

[0119] In some embodiments, the network device may switch between first configuration information and second configuration information based on a first condition. The terminal device may receive either the first configuration information or the second configuration information based on its own type. When the first terminal device is a first-type terminal device, the terminal device receives the first configuration information. When the first terminal device is a second-type terminal device, the terminal device receives the second configuration information.

[0120] In certain scenarios, since the second type of wake-up signal configured by the second configuration information can be used for both the first and second type of terminal devices, the first condition is mainly used to determine the transmission conditions of the first configuration information. That is, the first configuration information is transmitted based on the first condition. The first condition is at least one of the following: the size of the transmission resources for the current wake-up signal is lower than a set threshold; it is not currently necessary to configure the parameters of the second type of wake-up signal for the second type of terminal device; the currently transmitted paging group corresponds to the first modulation scheme.

[0121] As an example, the network device can select the transmission rules for the first configuration information. For instance, the network device may send the first configuration information only for OFDM-LP-WUR. In this case, the first condition (trigger condition) is that there is no active / registered OOK-UE in the cell.

[0122] As an example, it is not currently necessary to configure the parameters of the second type of wake-up signal for the second type of terminal devices. This can be understood as meaning that terminal devices registered or active in the cell where the terminal device is located do not belong to the second type of terminal devices.

[0123] As an example, if the transmission resource size for the current wake-up signal is lower than a set threshold, it indicates that the current transmission resources are relatively scarce. In situations of resource scarcity, network devices can prioritize sending first configuration information to send a first-type wake-up signal that consumes fewer resources.

[0124] As an example, the transmission of the first configuration information can be determined based on the paging group configuration. For instance, when the first wake-up signal is only used for paging OFDM-UEs, or when the corresponding paging group contains only OFDM-UEs, the network device can send the first configuration information.

[0125] As an example, the configuration parameters in the configuration information are related to the paging configuration and the state of the terminal device. When the terminal device is in the RRC idle / inactive state, the MO period is aligned with the default paging cycle by taking the least common multiple. When the terminal device is in the RRC state, moPeriodicityShort can be aligned with the C-DRX OnDuration and InactivityTimer, and can also be expanded once based on the conflictWithDRXHandling parameter if necessary.

[0126] In the example above, paging groups can also be divided based on the modulation scheme targeted by LP-WUR. For example, the MME / AMF side can maintain WUR-Type-aware paging groups, including OFDM-groups, OOK-groups, and hybrid groups. Network devices can then select different configuration information scenarios (Scenario A or Scenario B) and determine the code points and corresponding durations (X or Y).

[0127] The configuration information is used to indicate the configuration parameters of the first wake-up signal so that the terminal device can receive the first wake-up signal. The configuration parameters of the first wake-up signal include at least one of the following: the type of the first wake-up signal; the transmission resources corresponding to the first wake-up signal; the code point corresponding to the first wake-up signal; the parameters of the synchronization signal associated with the first wake-up signal; and the entry / exit conditions for the terminal device to monitor the first wake-up signal.

[0128] In some embodiments, the configuration information may indicate the type of low-power receiver corresponding to the first wake-up signal, or directly indicate the type of the first wake-up signal. When the configuration information is first configuration information, the first wake-up signal indicated by the configuration parameters is a first type of wake-up signal. When the configuration information is second configuration information, the first wake-up signal indicated by the configuration parameters is a second type of wake-up signal.

[0129] In some embodiments, the transmission resources of the first wake-up signal include one or more candidate MOs corresponding to the first wake-up signal. The MO can also be referred to as the LP-WUS timing. The one or more candidate MOs can be determined based on one or more of the following parameters: MO periodicity; MO offset; MO start time; and MO window length.

[0130] For example, the length of the MO window can be expressed in any of the following time units: milliseconds, number of time slots, or number of symbols. The length of the MO window needs to meet the transmission requirements of the wake-up signal. For example, when the MO is used to transmit a first type of wake-up signal, the MO window needs to include at least X (e.g., 2-3 or 4-6) available downlink (DL) symbols, where X is a positive integer. Similarly, when the MO is used to transmit a second type of wake-up signal, the MO window needs to include at least Y (e.g., 32) available downlink symbols, where Y is a positive integer.

[0131] For example, each candidate MO can be determined based on the start time of the MO and the length of the MO window. For instance, the i-th candidate MO among multiple candidate MOs is denoted as MO. i time, MO i =[t i ,t i +L MO], where i is a positive integer, t i for MO i The starting position of the window (i.e., the start time of the i-th MO), L MO This is the length of the MO window. Therefore, MO... i Window from t i Start, to t i +L MO End or at t i +L MO End before. Optional, t i It is usually taken on the boundary of a time slot or OFDM symbol.

[0132] For example, for MO i , t i It can be determined based on the period and offset of MO. The system reference time is t. ref For example, t i It can be represented as: t i =t ref +MO offset+i×MO periodicity. t ref For example, the position where SFN=0 is the starting point.

[0133] For example, within a MO cycle, the start time of a candidate MO can be calculated using the MO cycle and the number of candidate MOs in each cycle. S candidate MOs (equally spaced or defined patterns) can be generated within each cycle, where S is a positive integer. The interval between adjacent candidate MOs is in milliseconds / slots / symbols. The MO cycle length can be, for example, 40 / 80 / 160 milliseconds, etc. Assume the start time or beginning time t of the p-th cycle... per For: t per =t ref +p×P, where P is the period of MO (ms / slot). Under the equal-interval scheme, the interval Δ between adjacent candidate MOs within one period is: Rounding down ensures alignment to the selected time granularity. Based on this interval, the m-th candidate MO within the p-th period is: t MO =t per (p)+O+m×Δ, m=0,1,2,...,S-1. O is the MO offset, representing the time offset within one period, used to shift the candidate MO to the expected phase.

[0134] As an example, network devices can avoid conflicts by verifying MO windows. For instance, a network device can verify the window of candidate MOs based on any of the methods described above to determine whether the MO transmitting the first wake-up signal is experiencing a resource conflict.

[0135] As an example, when the transmission resources of the first wake-up signal conflict with other transmission resources, adjustments need to be made to the first wake-up signal or its transmission resources to avoid the conflict. For example, if MO i If any symbol within the window overlaps with the symbol set of the LP-SS, then the MO of the transmitted first wake-up signal... i Discard according to the rules, or transmit the first wake-up signal based on the first adjustment method.

[0136] In some embodiments, the resource that conflicts with the transmission resource of the wake-up signal is a first resource. When the transmission resource of the first wake-up signal overlaps with or conflicts with the first resource, the first resource cannot be used to transmit the wake-up signal. The first resource can be used to transmit one or more of the following: synchronization signals, control information, uplink (UL) data, or uplink information. For example, the first resource can be used to transmit SSB or LP-SS. Also, the first resource can belong to CORESET#0. That is, the first resource can be used to transmit PDCCH. Furthermore, the first resource may include uplink symbols for uplink transmission.

[0137] As an example, if CORESET#0 and LP-WUS overlap in the frequency domain, OFDM symbols configured for the Type-0 common search space (CSS) are considered unusable for LP-WUS transmission.

[0138] As an example, when the first resource is used to transmit LP-SS, its location can be determined based on the relevant parameters of the LP-SS. If the LP-SS overlaps (including partially overlaps) with available symbols in the LP-WUS MO for LP-WUS transmission in the time domain, the terminal device will not detect LP-WUS in that MO (i.e., the MO is discarded). Depending on the signal design, the length of each LP-SS transmission can be up to 8 OFDM symbols, and the duration of a single LP-SS burst transmission can be up to the frame level. For example, 8 beam transmissions in frequency range 1 (FR1) occupy a total of 8 time slots.

[0139] As an example, if the terminal device cannot perform full-duplex communication during the specified LP-WUS timing period, the N before the UL symbol... Rx-Tx N after the UL symbol Tx-Rx Symbols within this range cannot be used in LP-WUS. Furthermore, for unpaired spectrum, at least N prior to the effective random access channel occasion (RO). gap Symbols are not available for use in LP-WUS. Here, N represents the number of symbols.Rx-Tx N Tx-Rx and N gap The value can be determined based on higher-level signaling or pre-configuration information. For example, UL symbols / time slots configured based on TDD UL DL Configuration Common in relevant protocols are considered unsuitable for transmitting LP-WUS.

[0140] As an example, LP-WUS is not monitored when the end device transmits within a UL symbol. For TDD, semi-static rules can be formulated to resolve conflicts between LP-WUS transmissions and potential UL transmissions by network devices. For example, LP-WUS may not be transmitted within any UL symbol. The timing of the UL symbol can be determined by either logical time or physical time.

[0141] In some embodiments, when the transmission resources of the first wake-up signal at least partially overlap with the first resource, the transmission of the first wake-up signal is adjusted. Adjusting the transmission of the first wake-up signal includes adjusting the size of the first wake-up signal, adjusting the transmission resources of the first wake-up signal, and abandoning the transmission of the first wake-up signal. For example, when the first wake-up signal is a first type of wake-up signal, and the transmission resources of the first wake-up signal partially or completely overlap with the first resource, the network device abandons transmitting the first wake-up signal on that transmission resource, and the terminal device abandons receiving the first wake-up signal on that transmission resource. As another example, when the first wake-up signal is a second type of wake-up signal, and the transmission resources of the first wake-up signal partially or completely overlap with the first resource, the network device and the terminal device transmit the first wake-up signal based on a first adjustment method.

[0142] As an example, the first adjustment method includes at least one of the following adjustment methods: reducing the repetition factor of the first wake-up signal; adjusting the transmission resource to a spare resource within the same MO; adjusting the transmission resource from the current MO to the next MO; adjusting the first wake-up signal from a second type of wake-up signal to a first type of wake-up signal; and abandoning the transmission of the first wake-up signal.

[0143] Optionally, when a resource conflict occurs, the repetition factor K of the first wake-up signal only guarantees the necessary repetition. Preferably, K = 1.

[0144] Optionally, adjusting transmission resources to spare resources within the same MO may include time-domain shifting. For example, shifting the symbol transmitting the first wake-up signal to a spare, non-disabled OFDM symbol within the same MO.

[0145] Optionally, adjusting the transmission resource from the current MO to the next MO includes shifting the MO transmitting the first wake-up signal to the next MO.

[0146] Optionally, when the first wake-up signal is changed from a second type of wake-up signal to a first type of wake-up signal, the second configuration information is changed to the first configuration information. For example, the current situation B is downgraded to situation A, that is, only X symbols of OFDM (OFDM-only) are supported.

[0147] Optionally, the transmission of the first wake-up signal can be abandoned, that is, the current WUS can be abandoned. It should be noted that abandoning the transmission of the current WUS is only feasible when there is no OOK-UE to be paging or when the policy allows it.

[0148] Optionally, when the first adjustment method includes multiple adjustment methods, the multiple adjustment methods can sequentially perform rollback processing on the first wake-up signal based on a first order. As an example, when the transmission resource of the first wake-up signal overlaps with the first resource, one implementation of the first order is as follows: First, reduce the repetition factor of the first wake-up signal; second, adjust the transmission resource to a spare resource within the same MO; third, adjust the transmission resource from the current MO to the next MO; fourth, adjust the first wake-up signal from a second type of wake-up signal to a first type of wake-up signal; finally, abandon the transmission of the first wake-up signal.

[0149] To facilitate understanding, the following will be combined with... Figure 3 The following is an example of how to handle the situation where the transmission resources of the first wake-up signal overlap with the first resource. Figure 3 The method shown is executed by the network device, and the terminal device can also receive the first wake-up signal based on this processing method.

[0150] See Figure 3 In step S310, it is determined whether the transmission resources of the first wake-up signal overlap with the first resource. If yes, then step S330 is executed; if no, then step S320 is executed.

[0151] In step S320, the first wake-up signal is sent normally. The network device sends the first wake-up signal through this transmission resource.

[0152] In step S330, it is determined whether the first wake-up signal is a second type of wake-up signal. If yes, step S350 is executed; otherwise, step S340 is executed. In some cases, the network device may also determine the type of the first wake-up signal first, and then determine whether a resource conflict has occurred.

[0153] In step S340, the transmission of the first wake-up signal is abandoned. The network device abandons the transmission of this first wake-up signal.

[0154] In step S350, the repetition factor of the first wake-up signal is reduced. After reducing the repetition factor, it can be determined again whether the resources overlap.

[0155] In step S360, if the resources still overlap, the transmission resources of the first wake-up signal are adjusted to spare resources within the same MO. After adjusting the transmission resources, it can be determined again whether the adjusted transmission resources overlap with the first resource.

[0156] In step S370, if the resources still overlap, the transmission resource of the first wake-up signal is adjusted from the current MO to the next MO. After adjusting the transmission resource, it can be determined again whether the adjusted transmission resource overlaps with the first resource.

[0157] In step S380, if the resources still overlap, the first wake-up signal is changed from a second type of wake-up signal to a first type of wake-up signal. As mentioned above, the first type of wake-up signal occupies relatively less time-frequency resources, so resource overlap can be avoided by adjusting the type. After adjusting the type of the first wake-up signal, it can be determined again whether the transmission resources occupied by the first wake-up signal overlap with the first resource.

[0158] In step S390, if the resources still overlap, the transmission of the first wake-up signal is abandoned. The network device abandons the transmission of this first wake-up signal.

[0159] exist Figure 3 In this process, the first order is to adjust from step S350 to step S390 sequentially. For example, step S350 is executed first, and if there is no overlap, step S360 is executed, and so on. When the first adjustment method includes at least two of the adjustment methods from step S350 to step S390, the at least two adjustment methods can be executed with reference to the order from step S350 to step S390.

[0160] In some embodiments, the code point corresponding to the first wake-up signal can be indicated by the code point parameters detected by the terminal device. Different types of terminal devices handle the same code point parameters differently. For the first type of terminal device (e.g., OFDM-UE), listening begins within the configured MO. If codepointForOfdmOnly is detected, wake-up is completed after listening to xSymbolsForFullInfo or earlyStopMinSymbols. If codepointForMixed is detected, some symbols can be monitored first according to preset rules (e.g., 2-3 or 4-6 symbols based on the early stop strategy). If this fails, listening continues until Y is detected or invalidation is determined. For the second type of terminal device (e.g., OOK-UE), listening begins only when codepointForMixed or codepointForOokOn is detected, and wake-up is completed after listening to ySymbolsForFullInfo.

[0161] In some embodiments, parameters of the first synchronization signal associated with the first wake-up signal include a configuration threshold for the first synchronization signal and / or the quality of the first synchronization signal. The configuration threshold for the first synchronization signal can be indicated by the parameter LP-SSConfig.ThresholdOfdm. The quality of the first synchronization signal is, for example, the reference signal received power (RSRP) of the synchronization signal.

[0162] In some embodiments, the entry / exit conditions for the terminal device to monitor the first wake-up signal are also related to the type of low-power receiver. When the first type of terminal device only supports OFDM and the second type of terminal device supports both OFDM and OOK, the terminal device supporting OFDM can receive both the first and second types of wake-up signals. Therefore, the terminal device supporting OFDM can monitor the wake-up signal normally according to the configuration information without setting entry conditions. However, for the terminal device supporting OOK, it is necessary to enter the monitoring of the wake-up signal after meeting certain conditions. The conditions for the LP-WUR supporting OOK to enter the wake-up signal monitoring can be at least one of the following: within the configured MO window, the relevant peak value is greater than LP-SSConfig.ThresholdOfdm ​​and / or the RSRP of the received synchronization signal is greater than rsrpThresholdOfdm ​​for L consecutive times; within the MO window, the ON-chip duty cycle matches the energy threshold ≥ L times.

[0163] As an example, the conditions for LP-WUR to exit wake-up signal monitoring can be applied to different types of LP-WUR. The exit condition is at least one of the following: the failure count for the corresponding wake-up signal type is greater than a certain set value; or no PDCCH is received within a subsequent period after an early stop. When the exit condition is met, the terminal device can return to low power.

[0164] In some embodiments, for terminal devices in idle / inactive mode, the configuration information may specify the LP-WUS procedure and configuration, and may also indicate LP-WUS-triggered paging monitoring. The configuration information includes at least the LP-WUS monitoring configuration, sub-packets and entry / exit conditions, and LP-SS with a period of Tms for LP-WUS, used for synchronization of certain terminal devices and / or for specifying RRM for the serving cell.

[0165] In some embodiments, the configuration information may be proprietary LP-WUS configuration. This proprietary configuration may include one or more of the following: the receiver types supported by LP-WUS and the selection criteria; the receiver types that trigger / start LP-WUS monitoring; the principles of the early stop (early termination) policy for LP-WUS monitoring on the terminal device; and the monitoring limit of the terminal device.

[0166] As an example, the configuration information can indicate different thresholds for different receiver types through a list, so that the same LP-WUS presents different "entry probabilities" to terminal devices with different types of LP-WURs, achieving the effect of "emphasizing a certain type".

[0167] As an example, the terminal device can execute an early stop policy based on parameters indicated by higher-layer signaling. For instance, the terminal device can determine whether to terminate LP-WUS detection early based on RRC parameters.

[0168] As an example, examples and meanings of RRC parameters can be found in Table 2.

[0169] Table 2

[0170]

[0171]

[0172] In Table 2, M refers to the number of OOK symbols carried in each OFDM symbol.

[0173] As shown in Table 2, LP-WUS can transmit based on superimposed OFDM sequences. As mentioned earlier, LP-WUS can perform repeated transmissions. The parameters for repeated transmissions based on superimposed OFDM sequences can be found in Table 3.

[0174] Table 3

[0175]

[0176] In addition, the system can also configure other RRC parameters, such as LP-WUS_Mvalue_CONNECTED.

[0177] The aforementioned RRC parameters can support configuration for each cell group on the Pcell / PScell. For example, the system can configure LP-WUS with secondary DRX on a PCell with secondary DRX. LP-WUS with secondary DRX means that the terminal device periodically monitors LP-WUS before the duration or outside the active time. Typically, when LP-WUS is detected, the terminal device starts either drx-onDurationTimer or WUS-PDCCHMonitoringTimer in both DRX groups. If a secondary DRX group is configured, the terminal device only monitors LP-WUS when neither DRX group is in DRX active time. If a secondary DRX group is configured, the WUS-PDCCHMonitoringTimer configuration for the secondary DRX group can be the same as or different from the default DRX group configuration. For example, the WUS-PDCCH monitoring timer configuration for the secondary DRX group can be smaller than the default DRX group configuration.

[0178] For the RRC parameter WUS-PDCCHMonitoringTimer, a separate parameter can be defined / configured for each DRX group. The RRC parameter NumOfMO_Monitoring takes integer values. For the RRC parameter LP-WUS_TCI_state_CONNECTED, this parameter is configured on the Pcell / Pscell by BWP, and the configured CORESET#ID should be within the CORESET set configured for BWP.

[0179] If the system is configured with LP-SS and both SSB-based and LP-SS-based thresholds are configured for RRM measurements, then the terminal device decides which threshold to use.

[0180] If the system is configured with LP-SS overlay sequence, the terminal device can support all M values ​​of LP-SS, such as {1,2,4}, when performing LP-SS-based RRM measurements in idle / inactive mode.

[0181] In some embodiments, the terminal device can determine whether the type of the first wake-up signal matches the type of the terminal device based on configuration information, and then receive the first wake-up signal. When the type of the first wake-up signal matches the type of the terminal device, the terminal device receives and detects the first wake-up signal. When the type of the first wake-up signal does not match the type of the terminal device, the terminal device may receive and detect the first wake-up signal, or it may choose not to receive the first wake-up signal.

[0182] In some embodiments, configuration information is used by the terminal device to determine the type of the first wake-up signal. After determining the type of the first wake-up signal based on the configuration information, the terminal device may receive the first wake-up signal in one of the following ways: when the terminal device is a first type of terminal device and the first wake-up signal is a first type of wake-up signal, the terminal device receives all sequences of the first wake-up signal; when the terminal device is a first type of terminal device and the first wake-up signal is a second type of wake-up signal, the terminal device receives the first wake-up signal based on an early-stop policy; when the terminal device is a second type of terminal device and the first wake-up signal is a second type of wake-up signal, the terminal device receives all sequences of the first wake-up signal; when the terminal device is a second type of terminal device and the first wake-up signal is a first type of wake-up signal, the terminal device abandons receiving the first wake-up signal.

[0183] As an example, when the terminal device is a type 1 terminal device and the first wake-up signal is a type 1 wake-up signal, the time-frequency resources occupied by the first wake-up signal are determined based on the first modulation scheme. Since the first modulation scheme occupies relatively few time-frequency resources, the transmission duration of the first wake-up signal is short. Even if the terminal device receives the entire sequence of the first wake-up signal, it does not require a long time.

[0184] As an example, when the terminal device is a type 1 terminal device and the first wake-up signal is a type 2 wake-up signal, the time-frequency resources occupied by the second wake-up signal are determined based on the second modulation scheme. Since the first modulation scheme occupies relatively more time-frequency resources, the transmission duration of the first wake-up signal is longer. The terminal device can receive a portion of the first wake-up signal sequence based on an early-stop strategy to reduce resource consumption.

[0185] As an example, when the terminal device is a type 2 terminal device and the first wake-up signal is a type 2 wake-up signal, due to the limited low-power receiver capability of the terminal device, the terminal device needs to receive all sequences of the first wake-up signal to determine the first wake-up signal.

[0186] As an example, when the terminal device is a type 2 terminal device and the first wake-up signal is a type 1 wake-up signal, the terminal device cannot receive the first wake-up signal because the capabilities of the low-power receiver of the terminal device are not matched with the first wake-up signal.

[0187] In the above embodiments, the information carried by the first wake-up signal can be indicated based on a sequence. All sequences of the first wake-up signal refer to the complete sequence associated with the first wake-up signal.

[0188] The terminal device can determine whether it needs to be woken up based on the configuration information and / or the detection result of the first wake-up signal. The first wake-up signal can be used by the terminal device to determine whether the wake-up signal is related to itself. The configuration information can be used to determine whether the type of the first wake-up signal matches.

[0189] In some embodiments, the terminal device can determine whether the first wake-up signal is a wake-up signal for itself, thereby determining whether to be woken up. As one implementation, the first wake-up signal may carry an identifier of the terminal device to indicate the terminal device to which the wake-up signal is targeted. As one implementation, the first wake-up signal may carry the type of the terminal device to be woken up. As one implementation, the first wake-up signal may also carry information related to supporting other functions.

[0190] As an example, the first wake-up signal is one or more LP-WUS received by the terminal device, which can be replaced by the first LP-WUS.

[0191] As an example, the identity (ID) of a terminal device can be the ID of the terminal device itself, or the ID of the terminal device group or terminal device subgroup to which the terminal device belongs. Therefore, the ID of a terminal device is not necessarily the same as the ID of the terminal device itself.

[0192] The above text combined Figure 2 and Figure 3 This paper introduces several implementation methods for terminal devices to receive wake-up signals based on configuration information related to the modulation scheme of low-power receivers. The terminal device can monitor the wake-up signal based on one or more MOs indicated by the configuration information.

[0193] As mentioned above, the terminal device also needs to receive the first synchronization signal sent by the network device and measure the first synchronization signal. The following section will combine... Figure 4 and Figure 5 An embodiment of a method for a terminal device to receive a first synchronization signal and perform measurements will be described. Figure 4 A flowchart illustrating the method is shown. Figure 5 This illustrates a scenario where MO resources overlap with synchronization signals.

[0194] Figure 4 The method shown is also presented from the perspective of the interaction between terminal devices and network devices. For the sake of brevity, Figure 2 The terms already explained in the text will not be repeated. Figure 4 The method shown includes step S410, which is described below.

[0195] See Figure 4 In step S410, the terminal device receives a first synchronization signal sent by the network device. The type of the first synchronization signal is related to the type or modulation method of the low-power receiver of the terminal device. When the first terminal device is a type 1 terminal device, the first synchronization signal can be SSB; when the first terminal device is a type 2 terminal device, the first synchronization signal can be LP-SS. The following explanation uses LP-SS as an example.

[0196] In some embodiments, LP-SS can be configured based on higher-layer signaling. For example, higher-layer parameters related to LP-WUS can configure relevant LP-SS parameters. Furthermore, for LP-WUS operations in idle / inactive states, when higher-layer parameters enable LP-WUS functionality, relevant LP-SS parameters need to be configured. However, configuring relevant LP-SS parameters is not mandatory.

[0197] In some scenarios, LP-SS parameters must be configured for OOK-based LP-WURs to enable LP-WUS operations in idle / inactive states. In other scenarios, LP-SS parameters are configured only when configuring LP-SS. Therefore, these parameters are not mandatory when the network device enables LP-WUS functionality. If the network device only supports OFDM-based LP-WUS, LP-SS transmission is unnecessary and offers no benefit to either the network or the terminal. If only OFDM-based LP-WURs are supported, LP-SS parameters can be specified to be configured only when configuring LP-SS transmission; when the network device supports OOK-based LP-WURs, the LP-SS parameters are configured. Thus, in this case, the additional LP-SS configuration can indicate whether the network device supports only OFDM-based LP-WURs or both OFDM-based and OOK-based LP-WURs. Alternatively, the absence of LP-SS configuration parameters may implicitly indicate that LP-SS is not transmitted, therefore only OFDM-based LP-WURs are supported in the cell. It should be noted that this does not consider cases where network devices support LP-WUR based on OOK but are not configured or transmit LP-SS related parameters.

[0198] As an example, relevant parameters for LP-SS may include: LP-SS_Binary_Seq, LP-SS_Binary_Seq_Length, and LP-SS_periodicityoffset. Network devices can configure these parameters to instruct LP-SS transmission.

[0199] As an example, if the system is configured with LP-SS, the periodicity configuration of LP-SS can be determined based on a set of candidate values, such as {160ms, 320ms}. SFN0 can configure a time offset for the first LP-SS opportunity. If the period is 160ms, the candidate values ​​for the time offset are {0, 1, ..., 159}ms. If the period is 320ms, the candidate values ​​for the time offset are {0, 1, ..., 319}ms. The terminal device can determine the LP-SS opportunity based on one or two start symbol positions within the configured time slot. The candidate value range for each start symbol position is, for example, {0, 1, ..., 10}. If only one candidate value is configured, there is one LP-SS opportunity in one time slot. If two candidate values ​​are configured, there are two LP-SS opportunities in one time slot. For example, the terminal device can determine the first LP-SS based on the periodicity / offset configuration of LP-SS. Starting with the first LP-SS opportunity, LP-SS opportunities will appear in that time slot and the next (ceil(M1 / N)-1)DL time slot, where M1 is the number of SSBs determined based on the SSB location burst (InBurst) in SIB1, and N is the number of LP-SS opportunities in a time slot. The terminal device expects the time slot used for the first LP-SS opportunity to be a DL time slot. Specifically, a time slot is considered a DL time slot if all symbols in a given time slot are represented as DL symbols in the tdd UL DL Configuration Common.

[0200] In some embodiments, the network device can ensure that the transmissions of LP-SS and SSB of SIB1, and LP-SS and PDCCH, do not overlap in the time and frequency domains, and ensure that LP-SS symbols and UL symbols do not overlap in the time domain, and that the time interval (including valid RO) between LP-SS and UL symbols is equal to or greater than a predefined value. For example, in long burst / multi-beam scenarios, the non-overlap guarantee of LP-SS can be implemented in both the time and frequency domains. In the time domain, the network device can pre-add the entire burst window of LP-SS (which may be "frame-level", multi-beam serial, or ≤8 symbols / beam in a single transmission) to the prohibited transmission resource list; or, the network device can set a G_UL interval (including valid RO) between LP-SS and UL symbols, otherwise the symbol is considered unavailable. If LP-SS must cover a frame area, all MOs in that area can be automatically disabled / discarded. In the frequency domain, the network device can preferentially place LP-SS in resource block (RB) bands that do not intersect with the CORESET#0 and SSB frequency domains. If there is a risk of co-frequency between LP-SS and PDCCH (not CORESET#0), CORESET-free symbol / physical resource blocks (physical RB, PRB) should be selected first.

[0201] As an example, network devices can reuse the method for determining LP-WUS timing for LP-SS transmission resources. For instance, LP-SS resources may not be available for LP-SS transmission when they overlap with SSB or PDCCH transmissions of SIB1 in both the time and frequency domains, or when LP-SS symbols overlap with UL symbols, or when LP-SS symbols are within the time slot of UL symbols (including valid ROs).

[0202] As an example, there is no limit to the maximum frequency bandwidth covering LP-SS or SSB. For instance, the frequency resources for LP-SS can be outside the initial DL bandwidth part (BWP), or within the DL bandwidth part.

[0203] In some embodiments, the transmission resources of the first wake-up signal and the transmission resources of the first synchronization signal need to satisfy a certain relationship so that the terminal device can receive the synchronization signal and the wake-up signal successively. For example, the frequency domain resources of the first wake-up signal and the first synchronization signal belong to the same frequency band or bandwidth portion. Also, the time interval between the time domain resources of the first wake-up signal and the first synchronization signal is within a set range.

[0204] As an example, the frequency domain resources of both LP-WUS and LP-SS / SSB can be within the DL bandwidth. If the terminal device's MR and LP-WUR use a shared radio frequency (RF) module, transmitting LP-WUS / LP-SS within the initial DL BWP can significantly simplify terminal device implementation and signal design. Based on this approach, the terminal device avoids RF frequency tuning when switching between MR and LP-WUR operations, or before and after receiving SSB. Taking LP-SS as an example, whether the frequency bandwidth of LP-WUS / LP-SS is entirely within the initial DL BWP largely determines the implementation complexity of the terminal device.

[0205] As an example, the frequency domain resources for both LP-WUS and LP-SS / SSB can also be outside the DL bandwidth portion. There is no limit to the maximum frequency bandwidth that can be covered for LP-WUS and LP-SS / SSB. Taking LP-SS as an example, new terminal device capabilities can be defined to support LP-WUS / LP-SS frequency resources outside the initial DL BWP. If RF tuning is required when the LP-WUS / LP-SS frequency resources exceed the initial DL BWP, then the RF tuning time also needs to be defined. During RF tuning, the terminal device cannot receive LP-WUS. Therefore, the available symbols for LP-WUS transmission should exclude the RF tuning time.

[0206] As an example, if the resources configured for LP-WUS and SSB overlap in the time domain, these overlapping resources are not used for LP-WUS transmission. If LP-WUS and SSB are far apart in frequency, the LP-WUR of the end device may not be able to receive both simultaneously. In this case, the end device may not receive LP-WUS in the SSB symbol, similar to the case where SSB and LP-WUS resources overlap in the time domain. Alternatively, if the edge-to-edge frequency bandwidth of LP-WUS and SSB is greater than a threshold, the LP-WUR cannot receive both signals simultaneously within its RF bandwidth. In this case, the network device may also allow the LP-WUR to receive LP-WUS instead of SSB; otherwise, the end device might miss the LP-WUS transmitted by the network device. This also provides more OFDM symbols for LP-WUS transmission, which is particularly useful when LP-WUS duration is long.

[0207] In the example above, when the time-domain resources of the first wake-up signal and the first synchronization signal overlap and their frequency-domain resources are far apart, the LP-WUR of the terminal device cannot simultaneously receive both signals. To address this issue, the network device can be configured to include at least one synchronization signal within a discontinuous reception cycle, and the time-domain resources of this synchronization signal do not overlap with the time-domain resources of the first wake-up signal. This non-overlapping of time-domain resources can be achieved by limiting the minimum interval between the SSBs of adjacent discontinuous reception cycles.

[0208] For example, in order to prioritize the monitoring of LP-WUS by terminal equipment and ensure that OFDM-based LP-WUR can receive at least one SSB in each iDRX cycle, and that at least one SSB in each beam does not overlap with LP-WUS MO in time.

[0209] For example, in each idle / inactive DRX cycle, if the terminal device detects that the LP-WUS in the LP-WUS MO overlaps with the SSB in time but not in frequency domain, and no SSB is received, the minimum interval between SSBs in two iDRX cycles can be limited. In this way, the terminal device can also better track channel changes in the time domain.

[0210] To facilitate understanding, the following will be combined with... Figure 5 An example is provided. See [link to example]. Figure 5 The frequency domain resources of LP-WUS MO and SSB are all within the RF bandwidth of the terminal device. Figure 5 The two SSBs are located in two corresponding iDRX cycles. For example... Figure 5 As shown, the network device can ensure that at least one of the two SSBs does not overlap with any LP-WUS MO (including time-domain or frequency-domain overlap).

[0211] As an example, network devices can be configured to ensure that the interval between two SSBs within two iDRX cycles is not less than a threshold, so as to ensure that at least one SSB does not overlap with LP-WUS MO in the time domain.

[0212] The preceding text described an embodiment of a method for a terminal device to receive a first wake-up signal after measuring a synchronization signal. As mentioned earlier, the wake-up signal can be transmitted using an OOK chip. Determining the OOK chip corresponding to the wake-up signal is a crucial consideration. The following section uses the first wake-up signal as an example to illustrate the method for determining the OOK chip for transmitting the wake-up signal.

[0213] In some embodiments, the first wake-up signal is transmitted via a first chip. The first chip can be used to transmit overlapping OFDM sequences. To achieve fast LP-WUS detection, the network device needs to configure the necessary number of repetitions for the overlapping OFDM sequences. It should be noted that configuring excessive repetitions beyond the required amount may delay the terminal device's complete detection of LP-WUS. Excessive repetition of overlapping OFDM sequences may force the network device to transmit LP-WUS in additional MOs, thus unnecessarily consuming more energy. Therefore, the network device only explicitly allows repetition of overlapping OFDM sequences when necessary. For example, if a single transmission of the set of two overlapping OFDM sequences carrying code point values ​​is sufficient to cover LP-WUS in the cell, repeated transmission is unnecessary.

[0214] As an example, the first chip can be one or more chips to enable the transmission of the first wake-up signal. When the first chip is used to transmit overlapping OFDM sequences, the starting point t0 of the first chip is not in the prohibited transmission resource list.

[0215] As an example, the first chip is an OOK chip. In RRC connection mode, the network device can configure a first OOK-On-chip, i.e., the first chip. The OOK-On-chip can transmit overlapping OFDM sequences in the MO used for either a Type I wake-up signal or a Type II wake-up signal. For example, the network device can send overlapping OFDM sequences to the terminal device starting from the first chip.

[0216] As an example, a network device can configure different chip sets for different terminal devices. For instance, different terminal devices can be configured with different subsets of OOK-On-chips for overlapping OFDM sequences in the MO of OOK LP-WUS. Alternatively, for multiple terminal devices, the network device can configure non-overlapping subsets of ON-chips / slot offsets for each terminal device. The network device can be configured based on the terminal device's ID.

[0217] As an example, when repetitive transmission of the first wake-up signal is enabled, the network device configures a corresponding number of repetitions (repetition factor) and repetition mode for the first wake-up signal. Optionally, the repetition mode can be configured to indicate that the set of all overlapping OFDM sequences of a code point is repeated, or it can be configured that each individual overlapping OFDM sequence in the set is repeated first.

[0218] In some embodiments, the terminal device may receive a first wake-up signal based on the index of a first chip. The index of the first chip is the position number of the ON chip assigned to the terminal device by the network device in a single MO. The initial value of the index of the first chip can be 0.

[0219] As an example, the index of the first chip is determined based on one or more of the following: the ID of the terminal device; the number of repetitions of the first wake-up signal; the total number of chips corresponding to one MO; and the index of the MO corresponding to the first wake-up signal.

[0220] As an example, the index of the first chip can be one of the following:

[0221] chip index =(hash(UE) ID )+K)mod L;

[0222] chip index =(hash(UE) ID )+a·MO index +K)mod L;

[0223] Among them, UE ID This represents the terminal device ID, K represents the repetition factor of the first wake-up signal, L represents the total number of chips corresponding to one MO, and a and L are coprime numbers. index This represents the index of the MO corresponding to the first wake-up signal.

[0224] Optionally, the index of the first chip is determined based on the terminal device ID, K, and L, which can avoid conflicts between the same symbol / the same PRB.

[0225] Optionally, the fact that a and L are coprime means that a and L are coprime, which can effectively reduce collisions.

[0226] Optionally, L can be understood as the "bucket number" in the modulo operation. That is, the total number of allocable chip positions within a given bucket. Based on L, the range of the ON chip index is [0, L-1].

[0227] Optionally, for the repetition factor K, the network device is configured only with the minimum K required to meet the target false positive / false negative rate. Excessive repetition should be prohibited unless absolutely necessary to avoid delays in full detection and increased probability of conflicts with PDCCH / SSB caused by excessive repetition.

[0228] The above describes the method of transmitting the first wake-up signal based on the OOK chip. If the terminal device receives the first wake-up signal indicating that the terminal device needs to be woken up, the terminal device can activate the main communication module to detect the PDDCH.

[0229] In some embodiments, the terminal device begins monitoring the first wake-up signal based on the first MO within a configured time slot. The terminal device should begin monitoring WUS at the first WUS monitoring moment (MO) within the first time slot no earlier than the second time slot, wherein the drx-onDurationTimer will start at the time provided by timeOffsetCONNECTED and monitor multiple MOs (numMO).

[0230] As an example, constraints no earlier than the second time slot are determined based on an observation window. For instance, within the first cycle after the current RRCReconfig takes effect, the first monitored MO must satisfy: slotindex(t MO )≥1. In other words, at least one time slot should be reserved for startup protection to avoid placing the first monitoring in the 0th time slot at the beginning of the observation window.

[0231] As an example, the terminal device can report results for multiple time slots. It should be understood that the terminal device does not need to monitor WUS before the time slot in which drx-onDurationTimer begins. Furthermore, the terminal device does not need to monitor WUS within the reported number of time slots before the time slot in which drx-onDurationTimer will start. For example, the terminal device might report S slots for which WUS monitoring is not required. skip During the remaining time, the terminal device can select multiple candidate MOs to listen to.

[0232] In some embodiments, after the terminal device determines it has been woken up based on the first wake-up signal, it can continue monitoring the PDCCH. As an example, the terminal device can first identify the first MO being monitored, then begin monitoring the WUS, and continue monitoring the PDCCH. For instance, the terminal device can first select from the candidate set {t} MO Select the slot from (p,m) that satisfies "guard≥1slot". MO,1 Then let t on =t MO,1 +T off This is to monitor subsequent events within the same period. Where t...on It is the duration of continuous listening, T off It is the time of timeOffsetCONNECTED. The terminal device can be in the set {t} MO Select the earliest multiple values ​​from (p,m)}, but exclude those falling within the interval [t]. pmon_start -S skip ×T slot ,t pmon_start The MO (terminal device does not need to listen) of ] t pmon_start This refers to the start time of PDCCH monitoring after WUS is triggered, i.e., the start time of the WUS-PDCCHMonitoringTimer. Alternatively, the terminal device can determine t before determining the first MO by aligning timeOffsetCONNECTED to the start of the cycle, etc. pmon_start Then find the earliest multiple listenable MOs before it, while removing S. skip The MO in the window. Then, consider the earliest listening time as t. MO,1 And backtrack / verify using the following formula: t pmon_start =t MO,1 +T off .

[0233] As an example, when the terminal device decides to enter PDCCH listening based on the detected first wake-up signal, it can... pmon_start Start WUS-PDCCHMonitoringTimer (length can be T) mon The drx-onDurationtimer also starts at the same time or immediately after it. The two timers can be started together. Within a cycle, the interval between the MO (Mobile Originator) and the start of PDCCH monitoring, where the last wake-up signal actually listened to by the terminal device is located, is the minimum interval between MO and PDCCH monitoring.

[0234] As an example, the terminal device can be provided with the periodicity, periodic MO, and time offset relative to the start of a system frame with SFN0 by WUS-MOCONNECTED, so that the terminal device can determine one or more candidate MOs (WUS monitoring opportunities). The terminal device reports the duration of the time slot in milliseconds. When transmitting superimposed OFDM sequences via OOK chips, the minimum interval between MO and PDCCH listening is related to the number of OFDM symbols N1 used for the sequence index bearer and the number of sequence candidates L1 (the number of optional superimposed sequences on each OOK "ON" symbol). For example, when LP-WUS_num_overlaidSeq_CONNECTED>k is configured for the terminal device, and k>1, the time interval between the 2N1 / log2(L1)th OOK symbol of the last MO of multiple MOs in each cycle and the time slot where WUS-PDCCHMonitoringTimer will start is not less than the number of reported time slots; or, the time interval between the last OOK symbol of the last MO of each cycle and the time slot where WUS-PDCCHMonitoringTimer will start is not less than the number of reported time slots. Optionally, specifying the OOK symbol and t pmon_start Distance ≥ S skip ×T slot .

[0235] It should be noted that if k is not configured or k=1, the specified OOK symbol can be any OOK symbol used to send the wake-up signal. For example, checking the last OOK symbol of the last MO up to t. pmon_start Distance ≥ S skip ×T slot Optionally, the terminal device will only initiate the process at t if it detects a valid WUS in one or more of the monitored MOs. MO,1 +T off Start WUS-PDCCHMonitoringTimer and drx-onDurationtimer. Alternatively, regardless of whether WUS is detected, in t MO,1 +T off Start the WUS-PDCCHMonitoringTimer; however, if WUS is not detected, the terminal device can use a very short PDCCH monitoring window (T). mon (Very small) to listen to PDCCH.

[0236] As another example, if the terminal device determines to listen to the PDCCH based on the detected first wake-up signal, the terminal device can also simply start the drx-onDurationTimer.

[0237] As another example, if the terminal device determines to monitor the PDCCH based on the detected first wake-up signal, the terminal device can monitor based on the number of MOs per cycle after the time provided by timeOffsetCONNECTED. For example, the terminal device can determine when to start the WUS-PDCCHMonitoringTimer based on the start time of the first MO.

[0238] The above describes the process by which a terminal device is woken up based on a first wake-up signal and listens to the PDCCH. If the terminal device receives the first wake-up signal and finds that it does not need to be woken up, it may also need to receive and detect a second wake-up signal. The terminal device can receive the second wake-up signal after the first wake-up signal has been detected, or it can receive the second wake-up signal at the same time as detecting the first wake-up signal.

[0239] In some embodiments, after the terminal device receives a first wake-up signal according to configuration information, the terminal device may detect the first wake-up signal; and / or, the terminal device may receive a second wake-up signal according to configuration information. The reception time of the second wake-up signal overlaps with the detection time of the first wake-up signal, or the reception time of the second wake-up signal does not overlap with the detection time of the first wake-up signal.

[0240] As an example, after receiving an LP-WUS waveform at any MO, the low-power receiver of the terminal device requires a certain amount of time to perform LP-WUS detection processing. This low-power receiver may or may not support parallel processing of LP-WUS detection and waveform reception.

[0241] In some embodiments, whether the terminal device can process LP-WUS reception and detection in parallel depends on the capabilities and configuration of the terminal device. For example, if the terminal device's LP-WUS can be received and detected simultaneously within a single MO, parallel processing of reception and detection can be achieved. In this case, the terminal device does not need to operate MR and LR simultaneously, but only a simple implementation is required.

[0242] As an example, network devices can configure gaps between MOs to ensure sufficient time for LP-WUS processes and beam switching. To limit resource overhead, network devices can configure a common gap between two LP-WUS MOs and determine the start time position of subsequent LP-WUS MOs based on the previous LP-WUS MO.

[0243] The following is combined Figures 6 to 8 The relevant processes and time relationships are illustrated with examples.
