The present application does not limit the protocol type.

[0069] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0070] To facilitate a better understanding of the embodiments of the present application, the terminal energy saving based on the physical downlink control channel (PDCCH) related to the present application is described.

[0071] The evolution of 5G has placed higher demands on terminal energy conservation. For example, for the discontinuous reception (DRX) mechanism, during each activation period (On Duration), the terminal device needs to continuously detect the PDCCH to determine whether the base station has scheduled data transmission to it. The DRX mechanism includes configuring a DRX cycle for terminal devices in the RRC connected (RRC_CONNECTED) state. A DRX cycle consists of an "activation period (On Duration)" and an "opportunity for DRX" period. During the "On Duration" period, the terminal device monitors and receives downlink channels and signals including the PDCCH; during the "Opportunity for DRX" period, the terminal device does not receive downlink channels and signals such as the PDCCH to reduce power consumption.

[0072] When there is no data transmission, power consumption can be reduced by stopping the reception of PDCCH (PDCCH blind detection will be stopped at this time), thereby improving battery life. The basic mechanism of DRX is to configure a DRX cycle for the terminal device in the RRC connected state. As shown in Figure 2, the DRX cycle consists of an "activation period (On Duration)" and a "sleep period (Opportunity for DRX)": during the "On Duration" time, the terminal device monitors and receives PDCCH (activation period); during the "Opportunity for DRX" time, the terminal device does not receive PDCCH to reduce power consumption (sleep period). In addition, the transmission of paging messages is also a DRX mechanism in the RRC idle state. At this time, the DRX cycle is the period of the paging message. As can be seen from Figure 2, in the time domain, time is divided into continuous DRX cycles.

[0073] However, for most terminals, there may be no need to receive data transmission for a long time, but it is still necessary to maintain a regular wake-up mechanism to monitor possible downlink transmission. For such terminals, there is room for further optimization of power saving. Furthermore, an energy-saving signal is introduced for energy saving of terminals in the RRC_CONNECTED state to achieve further energy saving. The energy-saving signal is used in conjunction with the DRX mechanism, and the terminal receives an indication of the energy-saving signal before the DRX ON duration. When the terminal has data transmission in a DRX cycle, the energy-saving signal "wakes up" the terminal to monitor the PDCCH during the DRX On duration; otherwise, when the terminal has no data transmission in a DRX cycle, the energy-saving signal does not "wake up" the terminal, and the terminal does not need to monitor the PDCCH during the DRX On duration. Among them, the energy-saving signal is carried on the PDCCH channel and is carried through DCI format 2_6. The process of indicating whether the terminal monitors the PDCCH during the DRX On Duration through the energy-saving signal is shown in Figure 3.

[0074] Energy saving has been optimized for the process of receiving paging messages by terminals in the RRC idle state / RRC deactivated state, and similar energy-saving signals have been introduced. When receiving paging messages via DRX, there is a paging occasion (PO) within a DRX cycle. The terminal only receives paging messages during the PO and does not receive paging messages outside of the PO to achieve power saving. The paging radio frame (PF) indicates the system frame number on which the paging message should appear, and the PO indicates the possible time of appearance. A PF frame may include one or more POs. During each DRX cycle or paging cycle, the terminal only needs to monitor its own PO. The terminal calculates its corresponding PF and the position of the PO in the PF based on its own identifier (ID). Figure 4 shows the position of the PF within a paging DRX cycle and the position of the PO in the PF.

[0075] However, in actual situations, the probability of a UE being paged may not be high. The UE periodically detects the PDCCH at the corresponding PO, but fails to detect the paging indication information sent to itself, which results in a waste of power. In some embodiments, the energy-saving signal may also be referred to as a paging early indication (PEI), which is used to indicate whether the UE receives the paging PDCCH at the target PO before the target PO arrives. The energy-saving signal is carried on the PDCCH channel and is carried through DCI format 2_7. As shown in Figure 5, a energy-saving signal indicates whether UEs of one or more paging subgroups receive paging on the corresponding PF or PO.

[0076] Energy conservation for UEs in the RRC_CONNECTED state continues to be enhanced, with an enhanced solution for search space set group switching. This solution also includes a power-saving solution called PDCCH skipping, which allows users to skip PDCCH detection when necessary. Control information related to search space set group switching and PDCCH skipping is also carried on the PDCCH.

[0077] To facilitate understanding of the technical solutions of the embodiments of the present application, the terminal energy saving based on waking up the receiver related to the present application is explained.

[0078] To further save power in the terminal, a wake-up receiver is introduced to receive the wake-up signal. The wake-up receiver features extremely low cost, extremely low complexity, and extremely low power consumption. It primarily receives the wake-up signal through envelope detection. Therefore, the wake-up signal (WUS) received by the wake-up receiver differs from the modulation method and waveform of the signal carried by the PDCCH. The wake-up signal primarily consists of an envelope signal modulated by amplitude shift keying (ASK) on the carrier signal. The demodulation of the envelope signal is also primarily based on the energy provided by the wireless RF signal to drive a low-power circuit, so it can be passive. The wake-up receiver can also be powered by the terminal. Regardless of the power supply method, the wake-up receiver significantly reduces power consumption compared to the terminal's traditional receiver. The wake-up receiver can be integrated with the terminal as an additional module to the terminal receiver, or it can serve as a standalone wake-up function module for the terminal.

[0079] A system block diagram of a wake-up receiver in an embodiment of the present application can be shown in FIG6 . The wake-up receiver receives a wake-up signal and, if the terminal needs to turn on the main receiver, can instruct the terminal to do so, for example, by instructing the terminal to turn on the main receiver through a backscatter signal. Otherwise, the terminal's main receiver can be in a disabled state. It should be noted that the main receiver in FIG6 can also be referred to as a main transceiver.

[0080] In some embodiments, the wake-up receiver may also receive narrow bandwidth cellular network signals (eg, NR signals).

[0081] The wake-up receiver (WUR) does not need to be turned on and off to save power like a traditional receiver. Instead, it can be activated by the wake-up signal (WUS) at any time and receive wake-up information. The wake-up signal is mainly an envelope signal that performs ASK modulation on the carrier signal. For example, the wake-up signal (WUS) uses on-off keying (OOK) modulation. The modulation principle of OOK is to modulate the amplitude of the carrier signal to non-zero and zero values, corresponding to on (On) and off (Off), respectively, to represent the information bit. OOK is also known as binary amplitude shift keying (2ASK). As shown in Figure 7, bit 1 is modulated to on and 0 is modulated to off.

[0082] To facilitate understanding of the technical solutions of the embodiments of the present application, the problems solved by the present application are described below.

[0083] Waking up the UE's main receiver through a wake-up receiver can further save power. Before the UE's wake-up receiver receives the wake-up signal, it needs to obtain the relevant configuration of the wake-up signal to determine whether to enable the wake-up receiver and receive the wake-up signal. However, in the NR system, the required information for configuring the UE wake-up signal is a problem that needs to be solved.

[0084] Based on the above problems, this application proposes a terminal energy-saving solution, which clarifies the specific parameters contained in the relevant configuration of the wake-up signal, so that the terminal device can use the wake-up receiver to receive the wake-up signal based on the relevant configuration of the wake-up signal.

[0085] The technical solution of this application is described in detail below through specific embodiments.

[0086] FIG8 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG8 , the wireless communication method 200 may include at least part of the following contents:

[0087] S210: The network device sends first information; wherein the first information includes at least one of the following: power information of the wake-up signal, spatial information of the wake-up signal, transmission parameters of the wake-up signal, and time-frequency resource information of the wake-up signal; wherein the first information is used by the terminal device to receive the wake-up signal using the wake-up receiver;

[0088] S220: The terminal device receives the first information.

[0089] In an embodiment of the present application, the wake-up receiver has low energy consumption, such as less than a preset value. The wake-up receiver can obtain energy from the terminal device to which it belongs, or similarly to a zero-power device, obtain energy for communication, information collection, and processing through energy harvesting. Specifically, for example, the wake-up receiver can obtain energy through wireless power supply methods such as wireless radio frequency signals, solar energy, pressure, or temperature.

[0090] In the embodiment of the present application, the wake-up receiver may also be referred to as a low-power receiver or a zero-power receiver, or similar names, which is not limited in the present application.

[0091] In some embodiments, the wake-up signal may also be a power supply signal for waking up the receiver.

[0092] In some embodiments, the terminal device may include a wake-up receiver and a main transceiver (specifically, similar to the main receiver in Figure 6). The main transceiver may be a traditional transceiver (used to transmit and receive cellular network signals and channels). Unlike the main transceiver, the wake-up receiver is a receiver with extremely low or even zero power consumption. It uses similar technologies to Radio Frequency Identification (RFID), including passive, envelope detection, and energy harvesting. The wake-up receiver can be combined with the terminal device as an additional module to the main transceiver of the terminal device, or it can be a separate functional module of the terminal device.

[0093] It's important to note that the wake-up receiver features extremely low cost, complexity, and power consumption. It primarily receives signals through envelope detection. Demodulation of the envelope signal is also primarily accomplished by using low-power circuits powered by the RF signal, making it passive. Regardless of the power supply method, the wake-up receiver significantly reduces power consumption compared to the terminal device's main transceiver.

[0094] In some embodiments, the wake-up receiver may receive a wake-up signal and wake up the master transceiver based on the received wake-up signal. For example, the wake-up receiver may send a wake-up signal to the master transceiver to wake up the master transceiver.

[0095] In some embodiments, the wake-up receiver may use a first transmission mode to perform channel sensing, and the main transceiver may use a second transmission mode to perform channel sensing. Specifically, under the same conditions, such as when both are used for channel sensing, the energy consumption of the first transmission mode is less than the energy consumption of the second transmission mode. The wake-up receiver can be activated and provided with energy by a wireless radio frequency signal to drive the wake-up receiver to perform channel sensing, and further send indication information to the main transceiver when the result of the wake-up receiver sensing is that the channel is idle, which can be used to wake up or turn on the main transceiver to further occupy the channel and transmit and receive data.

[0096] In some embodiments, the terminal device may also receive other signals by waking up the receiver, such as receiving narrow-bandwidth cellular network signals (such as NR signals) by waking up the receiver.

[0097] In some embodiments, the first information may include relevant configurations of one or more wake-up signals, which is not limited in this embodiment of the present application.

[0098] In some embodiments, the first information may also be used by the terminal device to determine whether to use a wake-up receiver to receive a wake-up signal.

[0099] In some embodiments, the terminal device sends first indication information, where the first indication information is used to indicate whether the terminal device uses the wake-up receiver to receive the wake-up signal.

[0100] In some embodiments, the first information is carried by one of the following: system message, public radio resource control (RRC) signaling, dedicated RRC signaling, media access control layer control element (MAC CE), and physical layer signaling.

[0101] The technical solution of this application is described below through specific examples.

[0102] Example 1: When the first information includes at least power information of the wake-up signal, the power information of the wake-up signal includes but is not limited to at least one of the following:

[0103] The power corresponding to the high-level modulated resource elements in the amplitude modulation in the subcarrier set carrying the wake-up signal, the average power of the resource elements carrying the wake-up signal, the power offset value between the power of the wake-up signal and the first reference power, the ratio of the power of the wake-up signal to the first reference power, and the absolute power of the wake-up signal.

[0104] It should be noted that in the downlink power allocation of the NR system, the allocation of energy per resource element (EPRE) is constant, but there may be a certain power offset between the EPREs of different channels or signals. The EPRE of different channels or signals is generally set based on the power of the secondary synchronization signal (SSS) in the synchronization signal block (SSB) as the reference power. The power of SSS is indicated by the parameter ss-PBCH-BlockPower configured by high-level signaling. The transmission power of SSS is defined as the linear average power of the power of all resource elements (RE) carrying SSS within the working bandwidth. The EPRE of the Channel State Information Reference Signal (CSI-RS) configured by the network can be obtained by the EPRE of the SSS of the SSB with which it is quasi-co-located (QCL) and the power offset parameter powerControlOffsetSS configured by the higher layer, where powerControlOffsetSS indicates the power offset between the EPRE of the CSI-RS and the EPRE of the SSS. The power offset between the EPRE of the Physical Downlink Shared Channel (PDSCH) and the EPRE of the CSI-RS is indicated by the power offset parameter powerControlOffset configured by the higher layer. The ratio between the EPRE of the Physical Downlink Shared Channel Demodulation Reference Signal (PDSCH DMRS) and the EPRE of the PDSCH, and the ratio between the EPRE of the Physical Downlink Control Channel (PDCCH) and the EPRE of the CSI-RS are also specified in the standard. The EPRE information of the downlink channel or signal can be used by the UE to perform channel estimation, channel state information (CSI) reporting, link recovery, power control, and other processes based on the power information.

[0105] It should be noted that SSB can also be called synchronization signal / physical broadcast channel block (SS / PBCH block).

[0106] In Example 1, for the wake-up signal, the network device can set the power of the wake-up signal according to the cell size and / or the coverage requirement of the wake-up signal, and notify the terminal device. The power information of the wake-up signal helps the wake-up receiver to receive the wake-up signal. The terminal device can also determine the coverage performance of the wake-up signal based on the power information of the wake-up signal, thereby determining the reception performance of the wake-up signal (such as whether the reception of the wake-up signal is reliable), and further decide whether to use the wake-up receiver to receive the wake-up signal.

[0107] In some implementations of Example 1, the first reference power is an EPRE of a first cellular network signal having a QCL relationship with the wake-up signal.

[0108] In some implementations of Example 1, the first reference power is an EPRE of a first cellular network signal, or the first reference power is an EPRE of a first cellular network channel.

[0109] In some implementations of Example 1, the first cellular network signal includes but is not limited to at least one of the following: SSB, CSI-RS, Physical Downlink Control Channel Demodulation Reference Signal (PDCCH DMRS), Physical Downlink Shared Channel Demodulation Reference Signal (PDSCH DMRS).

[0110] In some implementations of Example 1, the first cellular network channel includes but is not limited to at least one of the following: PDCCH, PDSCH.

[0111] In some implementations of Example 1, the first reference power is agreed upon by a protocol, or the first reference power is configured by a network device.

[0112] In some implementations of Example 1, the power information of the wake-up signal is determined based on at least one of the following: a cell size, and a coverage requirement of the wake-up signal.

[0113] For the wake-up signal transmitted in the NR system, a more convenient method is to use an orthogonal frequency-division multiplexing (OFDM) modulation module to realize the waveform of the wake-up signal. The downlink signal can generate an NR signal and a wake-up signal through the same Fast Fourier Transform (FFT) / Inverse Fast Fourier Transform (IFFT) operation. Among them, the amplitude of the subcarriers in the subcarrier set carrying the wake-up signal is set to generate a wake-up signal, including an On waveform and an Off waveform. Specifically, the amplitude of some subcarriers in the subcarrier set carrying the wake-up signal is set to a non-zero value, which can generate an On waveform, and all subcarriers in the subcarrier set carrying the wake-up signal are set to zero value, which can generate an Off signal.

[0114] Specifically, the power of the wake-up signal can be expressed as the power corresponding to the RE in the On waveform or the high-level modulated RE in the amplitude modulation, or the average power of the RE carrying the wake-up signal. The power of the wake-up signal may have a certain power offset or ratio with the EPRE of the NR signal. For example, the power of the wake-up signal has a certain power offset with the power of the SSS. For example, the power offset can be -3dB, 0dB, 3dB, 6dB, etc.

[0115] Specifically, the power of the wake-up signal may have a certain power offset or ratio with the EPRE of other channels or signals, such as CSI-RS EPRE, PDSCH EPRE, PDSCH DMRS EPRE, PDCCH EPRE, and PDCCH DMRS EPRE.

[0116] For example, the power offset configuration signaling of the wake-up signal may be as shown in the following example.

[0117] WUS Resource::={

[0118] powerControlOffsetSS ENUMERATED{db-3,db0,db3,db6}

[0119] …

[0120] }

[0121] In some implementations of Example 1, the absolute power of the wake-up signal, such as the power of the SSB configured by ss-PBCH-BlockPower, ranges from (-60, ..., 50) dBm.

[0122] In some implementations of Example 1, the terminal device determines the reception performance of the wake-up signal based on the power information of the wake-up signal.

[0123] In some implementations of Example 1, the terminal device determines the reception performance of the wake-up signal based on the power information of the wake-up signal and the first measurement result.

[0124] In some implementations of Example 1, the terminal device determines the path loss of the wake-up signal based on the power information of the wake-up signal and the first measurement result.

[0125] Optionally, the first measurement result includes at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), and signal to interference plus noise ratio (SINR).

[0126] In Example 1, the first measurement result is a measurement result obtained by measuring by the master transceiver, or the first measurement result is a measurement result obtained by measuring by the wake-up receiver.

[0127] For example, the first measurement result is the measurement result of the cellular network signal, or the first measurement result is the measurement result obtained after the terminal device uses the main transceiver to measure the wake-up signal, or the first measurement result is the measurement result obtained after the terminal device uses the main transceiver to measure the cellular network signal that is transmitted with the same waveform as the wake-up signal, or the first measurement result is the measurement result obtained after the terminal device uses the wake-up receiver to measure the wake-up signal, or the first measurement result is the measurement result obtained after the terminal device uses the wake-up receiver to measure the cellular network signal that is transmitted with the same waveform as the wake-up signal.

[0128] In some implementations of Example 1, the terminal device sends the first measurement result. Specifically, for example, when the first measurement result is less than or equal to a first threshold, the terminal device sends the first measurement result.

[0129] Optionally, the first threshold is agreed upon by a protocol, or the first threshold is configured by a network device.

[0130] In Example 1, the network device can indicate the power offset parameter of the wake-up signal to the terminal device. The terminal device can use the power offset parameter to determine the reception performance of the wake-up signal. For example, the reception performance of the wake-up signal can be determined by combining the measurement results of the NR signal and the power offset parameter of the wake-up signal, and further determine whether to use the wake-up receiver to receive the wake-up signal. Optionally, the main transceiver directly measures the wake-up signal or a signal transmitted using the same waveform as the wake-up signal to obtain measurement results, such as the RSRP, RSRQ, SINR, etc. of the measurement signal. Optionally, the terminal device can feed back the measurement results to the network, so that the network or terminal determines not to receive the wake-up signal through the wake-up receiver, but to receive the relevant energy-saving signal through the PDCCH to achieve energy saving; otherwise, the wake-up signal is received through the wake-up receiver. Specifically, the terminal device can perform measurements while the main transceiver is operating and feedback the relevant information to the network device. Specifically, the terminal device can provide feedback based on a measurement threshold. When the measurement result falls below the measurement threshold, the feedback of the measurement result is triggered. Furthermore, if the wake-up receiver's capabilities allow for signal power measurement, the wake-up receiver can directly measure the received power of the wake-up signal or a signal transmitted using the same waveform as the wake-up signal, thereby determining whether to use the wake-up receiver to receive the wake-up signal. Furthermore, because the power of the wake-up signal and the CSI-RS EPRE can have a certain power offset, the network device can also estimate the wake-up signal reception performance based on the CSI report obtained from the terminal device's CSI-RS measurement results, thereby determining whether the terminal device receives the wake-up signal through the wake-up receiver.

[0131] Example 2: When the first information includes at least spatial information of the wake-up signal, the spatial information of the wake-up signal includes but is not limited to at least one of the following:

[0132] The Transmission Configuration Indicator (TCI) state associated with the wake-up signal, the resource index of the CSI-RS having a QCL relationship with the wake-up signal, the index of the SSB having a QCL relationship with the wake-up signal, the SSB index corresponding to the wake-up signal, and the first corresponding relationship;

[0133] The first corresponding relationship includes a mapping relationship between multiple wake-up signals and indexes of multiple SSBs, and the multiple wake-up signals at least include the wake-up signal.

[0134] In some implementations of Example 2, in the first corresponding relationship, wake-up signals in different time domains, frequency domains, or code domains correspond to different SSB indexes.

[0135] It should be noted that in NR systems, because the frequency band used is higher than that of LTE, the path loss of wireless signal transmission increases, and the wireless signal coverage decreases. In this case, using beamforming technology to form beams through the base station's multi-antenna system to increase the gain of the wireless signal and compensate for the path loss is a feasible method. Beams are directional, and a narrow beam can only cover part of the cell and cannot cover all users in the cell. As shown in Figure 9, the base station can send signals using four beams in different directions. For beam B2, only UE1 is covered, and UE2 is not covered.

[0136] Common channels and signals in the NR system, such as synchronization signals and broadcast channels, need to cover the entire cell through multi-beam scanning to facilitate reception by UEs within the cell. For UE-specific channels and signals, the base station will use beam management to send channels and signals to the UE using appropriate beams. In the NR system, the QCL relationship with the CSI-RS or SSB is used to define the spatial information of a channel or signal. For example, in the configuration information of the control resource set (CORESET) of the PDCCH and the reference signal, the resource index (index) of the CSI-RS or the index (index) of the SSB with a QCL relationship is defined through the QCL information therein to indicate the spatial information of the channel or signal.

[0137] In Example 2, in the configuration of the wake-up signal, in addition to configuring the resources of the wake-up signal, the spatial information of the wake-up signal also needs to be configured. Specifically, the spatial information of the wake-up signal can be configured by defining the QCL relationship between the wake-up signal and the NR signal or channel, such as having a QCL relationship with the CSI-RS or SSB. Specifically, the spatial information of the wake-up signal can also be indicated by the TCI state. In particular, when the terminal device is in the RRC deactivation (RRC_INACTIVE) or RRC idle (RRC_IDLE) state, the base station does not maintain the beam used by the terminal device. At this time, the downlink common channel or signal is sent in a beam scanning manner, such as PDCCH. By defining the correspondence between the monitoring time of the PDCCH and the SSB index, the beam direction adopted by the PDCCH sent at different monitoring times, that is, its spatial information, is determined. For the wake-up signal, by defining the correspondence between the wake-up signal in different time domains, frequency domains or code domains and the NR channel or signal, such as the SSB index, the multi-beam transmission of the wake-up signal can be defined. In this way, the spatial information of the wake-up signal is not indicated by explicit configuration information. Instead, according to predefined rules, wake-up signals in different time domains, frequency domains, or code domains correspond to different spatial information.

[0138] Specifically, as shown in FIG10 , WUS1 and WUS2 are wake-up signals configured by the network, wherein WUS1 and SSB1 have a QCL relationship, and WUS2 and SSB2 have a QCL relationship.

[0139] Example 3: When the first information includes at least a transmission parameter of a wake-up signal, the transmission parameter of the wake-up signal includes but is not limited to at least one of the following:

[0140] The modulation order of the wake-up signal, the coding mode of the wake-up signal, the coding rate of the wake-up signal, the transmission rate of the wake-up signal, and the symbol length of the wake-up signal.

[0141] Specifically, the wake-up signal sent by the network device can have different modulation orders, coding schemes, coding rates, information rates, and symbol lengths, resulting in different transmission performance and affecting the reception performance of the wake-up signal. The network device indicates the modulation order, coding scheme, coding rate, information rate, and symbol length of the wake-up signal. This not only facilitates the wake-up signal reception by the wake-up receiver of the terminal device, but also allows the device to use these parameters to estimate the reception performance of the wake-up signal, thereby determining whether to use the wake-up receiver to receive the wake-up signal and providing feedback to the network.

[0142] In Example 4, the first information further includes multiple sets of wake-up signal transmission parameters, where each set of the multiple sets of wake-up signal transmission parameters includes, but is not limited to, at least one of the following: modulation order, coding scheme, coding rate, transmission rate, symbol length, resource size, and power information. The network can select a specific transmission parameter combination based on the multiple sets of transmission parameters to meet different coverage requirements.

[0143] In some implementations of Example 4, the terminal device receives the wake-up signal using the wake-up receiver based on the multiple sets of wake-up signal transmission parameters. Specifically, for example, when receiving the wake-up signal, the terminal device may receive the wake-up signal based on the multiple sets of wake-up signal transmission parameters. That is, each time the terminal device receives the wake-up signal, the terminal device may receive the wake-up signal based on the multiple sets of wake-up signal transmission parameters.

[0144] In some implementations of Example 4, the terminal device receives the wake-up signal using the wake-up receiver according to a set of wake-up signal transmission parameters associated with the wake-up signal among the multiple sets of wake-up signal transmission parameters.

[0145] In some implementations of Example 4, the set of wake-up signal transmission parameters associated with the wake-up signal are obtained by the terminal device via the main transceiver, or the set of wake-up signal transmission parameters associated with the wake-up signal are obtained by the terminal device via the wake-up receiver. In other words, the network device can explicitly indicate the set of wake-up signal transmission parameters associated with the wake-up signal.

[0146] In some implementations of Example 4, the set of wake-up signal transmission parameters associated with the wake-up signal is determined based on the resource location of the wake-up signal, or based on a characteristic sequence in the wake-up signal. In other words, the network device can implicitly indicate the set of wake-up signal transmission parameters associated with the wake-up signal.

[0147] Optionally, the characteristic sequence is used by the wake-up receiver to synchronize or identify the wake-up signal, for example, by identifying the characteristic sequence through correlation reception.

[0148] For example, the network may indicate the transmission parameters through an NR channel or through a wake-up signal. For example, while the UE's main receiver is on, the network may receive a configuration of the transmission parameters for the wake-up signal sent by the network. While the UE's main receiver is off, the network may receive the wake-up signal through the wake-up receiver based on the transmission parameters.

[0149] Example 5: When the first information includes at least time-frequency resource information of the wake-up signal, the time-frequency resource information of the wake-up signal includes but is not limited to at least one of the following:

[0150] Frequency domain information of the wake-up signal, and time domain information of the wake-up signal.

[0151] In some implementations of Example 5, the frequency domain information of the wake-up signal includes at least one of the following: a frequency domain reference point associated with the wake-up signal, a frequency domain offset associated with the wake-up signal, a frequency domain bandwidth associated with the wake-up signal, a frequency domain range associated with the wake-up signal, a subcarrier spacing associated with the wake-up signal, and a reference subcarrier spacing associated with the wake-up signal.

[0152] It should be noted that in the NR system, the frequency domain position of the carrier on which the terminal device operates is configured by the network. The starting point of the frequency domain position of the carrier is based on a frequency domain reference point (point A) and a frequency domain offset. Combined with the size of the frequency domain bandwidth of the carrier configured by the network, the terminal device can obtain the frequency domain position of the carrier. Within the bandwidth of the carrier, the network device further configures the frequency domain position of the bandwidth part (Band Width Part, BWP), as shown in Figure 11.

[0153] In some implementations, the wake-up receiver is independent of the main transceiver, and its operating frequency domain position can be independent of the operating frequency domain position of the terminal's main transceiver. For example, the wake-up receiver can operate in a different frequency band from the main transceiver. In particular, for the problem of small coverage of the wake-up signal, the wake-up signal can be configured in a relatively low frequency band to improve coverage. From the perspective of the operator's cell deployment, the NR signal and the wake-up signal sent by the network are configured as close as possible to the frequency domain range, that is, within the range of the authorized spectrum obtained by the operator. The same operator may not obtain the right to use different frequency bands at the same time.

[0154] Based on the above considerations, the frequency domain location of the wake-up signal can be configured flexibly, but it does not necessarily have a necessary correlation with the frequency domain location of the main transceiver. Therefore, the frequency domain location of the wake-up signal can have its own independent configuration, including but not limited to: frequency domain reference point, frequency domain offset, frequency domain bandwidth, reference subcarrier spacing, etc. Among them, the frequency domain location of the wake-up signal can be the frequency domain bandwidth where the wake-up signal is located, and the frequency domain bandwidth can also include the frequency domain resources of multiple frequency-divided wake-up signals.

[0155] In some implementations, the reference subcarrier spacing may be used to calculate an actual frequency domain size corresponding to a frequency domain offset or a frequency domain bandwidth expressed in terms of the number of physical resource blocks (PRBs).

[0156] In some implementations, the frequency domain bandwidth of the wake-up signal includes frequency domain resources of multiple wake-up signals that are frequency-divided from the wake-up signal.

[0157] In some implementations, the frequency domain reference point of the wake-up signal is the starting point of the frequency domain position of the carrier associated with the wake-up signal, or the frequency domain reference point of the wake-up signal is the starting point of the frequency domain position of the BWP associated with the wake-up signal.

[0158] For example, in the configuration of the frequency domain position where the wake-up signal is located, the frequency domain reference point can reuse the reference point A (Point A) of the NR system, or it can be configured separately, such as reference point B (Point B), as shown in Figure 12.

[0159] Specifically, the frequency domain reference point can also be the starting point of the frequency domain position of the configured carrier. In this case, the frequency domain position of the wake-up signal can be within the frequency domain bandwidth of the carrier or outside the frequency domain bandwidth of the carrier. Furthermore, in the configuration of the frequency domain position of the wake-up signal, the frequency domain reference point can also be the starting point of the frequency domain position of the configured BWP. The BWP can be BWP#0 or a BWP with a non-zero BWP identifier, as shown in Figures 13 and 14.

[0160] In some implementations, the frequency domain bandwidth associated with the wake-up signal belongs to multiple frequency domain bandwidths, wherein the multiple frequency domain bandwidths are determined based on the type of the wake-up receiver and / or the capabilities of the wake-up receiver; or, the frequency domain range associated with the wake-up signal belongs to multiple frequency domain ranges, wherein the multiple frequency domain ranges are determined based on the type of the wake-up receiver and / or the capabilities of the wake-up receiver.

[0161] Specifically, due to the extremely low complexity of the wake-up receiver, its operating frequency band may be relatively inflexible, or even fixed to a few frequency ranges and bandwidths, depending on the type and capabilities of the wake-up receiver. In this case, the network may only need to configure the frequency domain location of the wake-up signal by indicating one or more of a limited number of frequency ranges and bandwidths. The terminal device can report the type or capabilities of the wake-up receiver to the network to facilitate relevant configuration.

[0162] In some implementations, when the wake-up signal is transmitted using multiple carriers, the frequency domain information of the wake-up signal includes the subcarrier spacing associated with the wake-up signal. For example, if the frequency domain location of the wake-up signal is within the first BWP, the subcarrier spacing used to transmit the wake-up signal is the same as the subcarrier spacing configured for the first BWP.

[0163] In some implementations, the frequency domain location occupied by the wake-up signal is located in a licensed spectrum, or the frequency domain location occupied by the wake-up signal is located in an unlicensed spectrum.

[0164] In some implementations of Example 5, the time domain information of the wake-up signal includes but is not limited to at least one of the following:

[0165] The radio frame associated with the wake-up signal, the subframe associated with the wake-up signal, the time slot associated with the wake-up signal, the symbol associated with the wake-up signal, and the time domain length corresponding to the wake-up signal.

[0166] For example, the time domain length corresponding to the wake-up signal can be limited by an upper limit value and a lower limit value, and the upper limit value and the lower limit value can be determined based on the capabilities of the terminal device.

[0167] It should be noted that although the wake-up receiver can operate with extremely low power consumption and receive the wake-up signal at any time, the network can still configure the time domain location of the wake-up signal so that the wake-up receiver of the terminal device can receive it at the corresponding time domain location. At the same time, different wake-up signals can also be time-division multiplexed, and different time domain locations can correspond to different spatial information. For example, the time domain location can be used as an implicit way to indicate the spatial information of the wake-up signal.

[0168] For example, the time slot associated with the wake-up signal and the symbol associated with the wake-up signal can be based on a reference subcarrier spacing. The subcarrier spacing used by the wake-up signal can also be the subcarrier spacing of the BWP configuration where the frequency domain position of the wake-up signal is located, that is, the wake-up signal and the NR signal use the same subcarrier spacing within the BWP.

[0169] Therefore, in the embodiments of the present application, it is clarified that the configuration related to the wake-up signal may include at least one of the following: power information of the wake-up signal, spatial information of the wake-up signal, transmission parameters of the wake-up signal, and time-frequency resource information of the wake-up signal. Thus, the terminal device can use the wake-up receiver to receive the wake-up signal based on the configuration related to the wake-up signal.

The following text, in combination with Figures 15 to 19, describes in detail the device embodiment of the present application. It should be understood that the device embodiment and the method embodiment correspond to each other, and similar descriptions can refer to the method embodiment.
