[0058] Before introducing the technical solution of this application, some background technical knowledge involved in this application will be introduced and explained. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents:

[0059] 1) Terminal energy saving based on wake-up receiver

[0060] To further conserve power in User Equipment (UE), the 3GPP R18 standard considers introducing a Wake-Up Receiver (WUR) to receive a Low Power Wake-Up Signal (LP-WUS). The WUR features extremely low cost, low complexity, and extremely low power consumption, primarily receiving the wake-up signal through envelope detection. Therefore, the LP-WUS received by the WUR differs from the signals carried by the Physical Downlink Control Channel (PDCCH) as defined in existing 3GPP R16 and R17 standards in terms of modulation methods and waveforms. The wake-up signal is mainly an envelope signal modulated by Amplitude Shift Keying (ASK) on the carrier signal. Demodulation of the envelope signal is also primarily achieved by driving low-power circuitry powered by the radio frequency signal, thus it can be passive. The WUR can also be powered by the terminal itself; regardless of the power supply method, this receiver significantly reduces power consumption compared to traditional UE receivers. The wake-up receiver can be integrated with the UE as an additional module of the UE receiver, or it can stand alone as a wake-up function module of the UE.

[0061] Figure 2 shows a block diagram of the receiver system involved in this application. As shown in Figure 2, the wake-up receiver receives a wake-up signal. If the UE needs to turn on the receiver, it can instruct the UE to turn on the main receiver. Otherwise, the UE's main receiver can be in a turned-off state.

[0062] 2) Wake-up signal generation method based on wake-up receiver

[0063] To achieve power saving in the wake-up receiver, the receiver needs to have low complexity. Therefore, the wake-up signal waveform uses waveforms such as ASK and Frequency Shift Keying (FSK), which can be detected by receivers with low complexity. ASK waveforms typically use On-Off Keying (OOK) signals. Furthermore, in existing Orthogonal Frequency Division Multiplexing (OFDM) systems, to utilize existing OFDM transmitters to generate the wake-up signal and reduce additional hardware overhead, the OOK signal is generated through multi-carrier (MC) modulation, hence the name MC-OOK signal. MC-OOK signal generation can utilize existing multi-carrier modulation (such as OFDM modulation) to generate the OOK signal, maintaining good compatibility with existing OFDM systems and reducing the transmitter complexity introduced by implementing the WUR signal.

[0064] The 3GPP R18 standard discusses several main methods for generating WUS signals:

[0065] The MC-ASK waveform is generated using several methods, where K is the number of points in the Inverse Discrete Fourier Transform (IDFT), and N is the number of subcarriers used to transmit the WUS signal:

[0066] ①OOK-1: Each OFDM symbol carries 1 bit. The output signal corresponding to the LP-WUS subcarrier after modulation and IDFT transformation is OOK=1, and the output signal corresponding to the LP-WUS subcarrier having zero power is OOK=0. Figure 3 shows a schematic diagram of an LP-WUS generation process involved in this application.

[0067] ②OOK-2: Each OFDM symbol carries M bits in the frequency domain. The N subcarriers carrying LP-WUS are divided into M segments, each carrying 1 bit of information. In each segment, the output signal corresponding to all subcarriers being modulated is OOK = 1, and the output signal corresponding to all subcarriers having zero power is OOK = 0. Taking M = 2 as an example, Figure 4 shows a schematic diagram of another LP-WUS generation process involved in this application.

[0068] ③OOK-3: Each OFDM symbol carries 1 bit, and the N subcarriers carrying LP-WUS are divided into M segments. In each of the M segments, when one subcarrier in each segment is modulated and the other subcarriers are at zero power, the corresponding output signal is OOK = 1; when all subcarriers in all segments are at zero power, the corresponding output signal is OOK = 0. Figure 5 shows a schematic diagram of another LP-WUS generation process involved in this application.

[0069] ④OOK-4: Each OFDM symbol carries M bits in the time domain. The N subcarriers carrying LP-WUS are generated through Discrete Fourier Transform (DFT). M bits are represented by S sampling points. These S sampling points are then transformed by the DFT to form S subcarriers. These S subcarriers are truncated to form N subcarriers, which are then transformed by the IDFT to generate the OOK signal. Taking M=4 as an example, Figure 6 shows another schematic diagram of the LP-WUS generation process involved in this application.

[0070] In addition to MC-ASK waveforms, LP-WUS can also use MC-FSK waveforms, mainly including the following methods:

[0071] ①FSK-1: N subcarriers carrying LP-WUS are divided into M pairs of segments. In each OFDM symbol, one segment in each pair is modulated and the other segment is at zero power.

[0072] ②FSK-2: The N subcarriers carrying LP-WUS are divided into 2 M Each segment, in each OFDM symbol, 2 M One segment of the data is modulated, while the other segments are at zero power.

[0073] 3) Public PUCCH resources

[0074] During the initial access phase of the UE, such as in random access, it is necessary to send Hybrid Automatic Repeat Request (HARQ) feedback information for Msg4 or MsgB via the Common Physical Uplink Control Channel (PUCCH). Since there is no dedicated PUCCH resource set configured for the UE at this time, a predefined approach is used. The predefined PUCCH resource set is only used for HARQ feedback information; therefore, the PUCCH resources in the predefined PUCCH resource set only need to carry 1-2 bits of HARQ feedback information, i.e., only PUCCH format 0 and PUCCH format 1. The base station configures a common PUCCH resource set for the UE before all Radio Resource Control (RRC) is established via System Information Block (SIB) 1. The frequency domain location of the PUCCH resource is located at both ends of the initial uplink bandwidth (BWP). The frequency domain location of the PUCCH is determined by a frequency domain offset from the bandwidth edge. This avoids the PUCCH occupying the middle of the bandwidth, causing frequency domain fragmentation. Otherwise, the network cannot schedule the Physical Uplink Shared Channel (PUSCH) transmission on contiguous frequency domain resources within the initial uplink BWP, resulting in the PUSCH not obtaining sufficient scheduling resources. Figure 7 shows a schematic diagram of the frequency domain resource location of the PUCCH involved in this application. As shown in Figure 7, the frequency domain location of the PUCCH is determined by subtracting a frequency domain offset from the high-frequency edge of the initial uplink BWP bandwidth, or adding a frequency domain offset to the low-frequency edge, thus ensuring the largest possible contiguous bandwidth in the middle of the initial uplink BWP.

[0075] In the 3GPP R18 standard, LP-WUS was introduced. In order to be compatible with existing systems and make full use of resources, when terminal equipment uses WUR to receive WUS, the WUS signal sent by the network equipment should preferably be compatible with the existing OFDM transmitter and be able to be reused in the frequency band with the existing NR signal, rather than using a separate frequency band resource for the transmission of WUS signal.

[0076] The primary application scenario for LP-WUS is to indicate whether a UE in an RRC idle / inactive state needs to activate its primary receiver to receive paging messages. Since UEs in RRC idle / inactive states typically operate in the initial BWP, its initial downlink BWP is mainly used to transmit system messages, paging messages, and downlink messages (Message, Msg) for random access, while the initial uplink BWP is mainly used to transmit uplink Msg messages for initial access. As a downlink signal, how LP-WUS can coexist with other signals in the initial downlink BWP is a problem that needs to be solved.

[0077] In existing technologies, during the cell search phase, the initial downlink BWP is determined by the bandwidth of the control resource set (CORESET) #0 carried by the Physical Broadcast Channel (PBCH). After obtaining system messages, the initial downlink BWP can be indicated through system messages. The initial downlink BWP can carry PDCCH, Physical Downlink Shared Channel (PDSCH), Synchronization Signal Block (SSB), etc. The bandwidth of PDCCH is determined by CORESET, and PDCCH can schedule the frequency domain resources of PDSCH to carry system messages, paging messages, etc. Since system messages and paging messages are common messages, scheduling as much frequency domain resources as possible is beneficial to the payload and coverage carried by PDSCH. Therefore, avoiding frequency domain resource fragmentation is necessary.

[0078] Please refer to Figure 8, which shows a flowchart of a resource determination method provided in an embodiment of this application. This method can be interactively executed by a terminal device and a network device. The terminal device can be terminal device 120 or terminal device 130 in the network architecture shown in Figure 1, and the network device can be network device 110 in the network architecture shown in Figure 1. The method may include the following steps:

[0079] Step 801: The network device determines the wake-up frequency domain resource based on the frequency domain offset. The frequency domain offset is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located.

[0080] In other words, network devices can determine the wake-up frequency domain resource based on the frequency domain offset, which is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located.

[0081] Specifically, the frequency domain offset can be the offset between the wake-up frequency domain resource and either side of the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located, or the offset between the two sides of the frequency domain bandwidth edge of the wake-up frequency domain resource and the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located.

[0082] For example, the aforementioned wake-up frequency domain resource can be a frequency domain resource corresponding to a continuous frequency domain resource interval. In this case, the aforementioned frequency domain offset can be the offset between an interval endpoint of the frequency domain resource interval and the frequency domain bandwidth edge on either side of the downlink BWP.

[0083] For example, the aforementioned wake-up frequency domain resources may include frequency domain resources corresponding to two or more consecutive frequency domain resource intervals. In this case, the aforementioned frequency domain offset may include the offset between an endpoint of each frequency domain resource interval and the frequency domain bandwidth edge on either side of the downlink BWP.

[0084] For example, the aforementioned wake-up frequency domain resources may include frequency domain resources corresponding to two consecutive frequency domain resource intervals. Frequency domain resource interval 1 is closer to the low-frequency point in the downlink BWP, and frequency domain resource interval 2 is closer to the high-frequency point in the downlink BWP. The aforementioned frequency domain offset may include the offset between an interval endpoint of frequency domain resource interval 1 (e.g., the interval endpoint with a high frequency point) and the frequency domain bandwidth edge on the side of the low-frequency point in the downlink BWP, and the offset between an interval endpoint of frequency domain resource interval 2 (e.g., the interval endpoint with a high frequency point) and the frequency domain bandwidth edge on the side of the high-frequency point in the downlink BWP.

[0085] Step 802: The terminal device determines the wake-up frequency domain resource based on the frequency domain offset. The frequency domain offset is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion BWP where the wake-up frequency domain resource is located.

[0086] In other words, the terminal device can determine the wake-up frequency domain resource based on the frequency domain offset, which is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located.

[0087] Step 803: According to the wake-up frequency domain resources, the network device sends a wake-up signal; correspondingly, the terminal device can receive the wake-up signal through the first receiver, and the wake-up signal is used to wake up the second receiver of the terminal device.

[0088] In other words, the network device sends a wake-up signal according to the wake-up frequency domain resource, and the terminal device chooses whether to receive the wake-up signal. If it receives the signal, it receives the wake-up signal through the first receiver according to the wake-up frequency domain resource. The wake-up signal is used to wake up the second receiver of the terminal device.

[0089] In this embodiment of the application, the wake-up signal may be LP-WUS, and the downlink bandwidth portion BWP may be the initial downlink BWP.

[0090] In the above scheme, the network device can determine whether to carry LP-WUS on one or both sides of the frequency domain resources of the downlink BWP. Correspondingly, the terminal device can receive LP-WUS on one or both sides of the frequency domain resources of the downlink BWP. This method can avoid the fragmentation of frequency domain resources within the initial downlink BWP and reduce the impact on the resource usage of existing NR signals within the initial downlink BWP.

[0091] In addition to the initial downlink BWP, the method of this application embodiment can also be used if the LP-WUS signal is transmitted in a non-initial downlink BWP. For example, when the UE is in the RRC-connected state, in the downlink BWP configured by the network device through RRC signaling, the terminal device and the network device can also determine the frequency domain location of the wake-up frequency domain resource of the LP-WUS signal according to the above method.

[0092] In summary, the solution shown in this application embodiment can determine the wake-up frequency domain resources for the network device to send wake-up signals and the terminal device to receive wake-up signals based on the frequency domain offset. The frequency domain offset is the offset between the wake-up frequency domain resources and the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resources are located. This enables the network device and the terminal device to accurately transmit and receive wake-up signals, improves the efficiency of wake-up signal transmission and reception, and further improves the energy-saving effect of the system.

[0093] Furthermore, LP-WUS can be carried on one or both sides of the frequency domain resources of the downlink BWP. When the wake-up signal is multiplexed with the existing NR signal, it can avoid the fragmentation of the frequency domain resources of the downlink bandwidth BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth BWP, and not affect the use of the frequency domain resources of the existing downlink signal, thus ensuring the transmission performance of the existing downlink signal.

[0094] Based on the scheme shown in Figure 8 above, please refer to Figure 9, which shows a flowchart of a resource determination method provided in an embodiment of this application. This method can be interactively executed by a terminal device and a network device. The terminal device can be terminal device 120 or terminal device 130 in the network architecture shown in Figure 1, and the network device can be network device 110 in the network architecture shown in Figure 1. The method can include the following steps:

[0095] Step 901: The network device sends resource indication information to the terminal device. Correspondingly, the terminal receives the resource indication information, which is used to indicate the frequency domain offset.

[0096] In other words, the aforementioned frequency domain offset can be indicated by resource indication information, which is sent by the network device.

[0097] In other words, the resource indication information sent by the network device can be used to indicate the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink BWP where the wake-up frequency domain resource is located.

[0098] For example, network devices can use system messages, RRC messages, or Medium Access Control-Control Element (MAC-CE) signals to indicate the frequency domain offset of LP-WUS wake-up frequency domain resources from the high-frequency edge or the low-frequency edge.

[0099] Among them, system messages can indicate the frequency domain offset of the start or end point of LP-WUS wake-up frequency domain resources from the high / low frequency edge.

[0100] In this embodiment, the wake-up frequency domain resource of the wake-up signal can be determined based on the offset between the wake-up frequency domain resource indicated by the resource indication information and the downlink BWP where the wake-up frequency domain resource is located. This enables accurate transmission and reception of the wake-up signal between the network device and the terminal device, improves the efficiency of wake-up signal transmission and reception, and further enhances the energy-saving effect of the system.

[0101] In this embodiment of the application, the wake-up signal may be LP-WUS, and the downlink bandwidth portion BWP may be the initial downlink BWP.

[0102] It should be noted that, for downlink BWP (such as the initial downlink BWP), in order to avoid fragmentation of frequency domain resources, the wake-up frequency domain resources of LP-WUS can be set at one or both ends of the downlink BWP, or at a frequency domain position close to one or both ends of the downlink BWP.

[0103] In other words, the frequency domain resources used to carry LP-WUS on one or both sides of the downlink BWP can be determined by the resource indication information sent by the network device. This method can avoid the fragmentation of frequency domain resources within the initial downlink BWP and reduce the impact on the resource usage of existing NR signals within the initial downlink BWP.

[0104] In addition to the initial downlink BWP, the method of this application embodiment can also be used if the LP-WUS signal is transmitted in a non-initial downlink BWP. For example, when the UE is in the RRC-connected state, the wake-up frequency domain resource location of the LP-WUS signal can also be determined according to the above method in the downlink BWP configured by the network device through RRC signaling.

[0105] The solution shown in this application embodiment can indicate the frequency domain offset by the resource indication information sent by the network device, so as to determine the wake-up frequency domain resources of the wake-up signal, avoid the fragmentation of the frequency domain resources of the downlink bandwidth portion BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion BWP, not affect the use of the frequency domain resources of the existing downlink signal, and ensure the transmission performance of the existing downlink signal.

[0106] Step 902: The network device determines the wake-up frequency domain resource based on the frequency domain offset. The frequency domain offset is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located.

[0107] In other words, network devices can determine the wake-up frequency domain resource based on the frequency domain offset, which is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located.

[0108] Specifically, the frequency domain offset can be the offset between the wake-up frequency domain resource and either side of the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located, or the offset between the two sides of the frequency domain bandwidth edge of the wake-up frequency domain resource and the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located.

[0109] Step 903: The terminal device determines the wake-up frequency domain resource based on the frequency domain offset. The frequency domain offset is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion BWP where the wake-up frequency domain resource is located.

[0110] In other words, the terminal device can also determine the wake-up frequency domain resource based on the frequency domain offset, which is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located.

[0111] Step 904: According to the wake-up frequency domain resources, the network device sends a wake-up signal; correspondingly, the terminal device can receive the wake-up signal through the first receiver, and the wake-up signal is used to wake up the second receiver of the terminal device.

[0112] Among them, the terminal device can receive the wake-up signal on the wake-up frequency domain resources through the first receiver.

[0113] In other words, the network device sends a wake-up signal based on the wake-up frequency domain resource. The terminal device can choose whether to receive the wake-up signal. If it does, it receives the wake-up signal through the first receiver based on the wake-up frequency domain resource. The wake-up signal is used to wake up the second receiver of the terminal device.

[0114] In some embodiments, the resource indication information is also used to indicate the bandwidth of the wake-up frequency domain resource.

[0115] In other words, the resource indication information sent by network devices can be used not only to indicate the frequency domain offset, but also to indicate the bandwidth of the wake-up frequency domain resources.

[0116] This application embodiment further clarifies that the resource indication information sent by the network device can also be used to indicate the bandwidth of the wake-up frequency domain resources, which can improve the flexibility of indicating the wake-up frequency domain resources in this application embodiment.

[0117] In other embodiments, the bandwidth of the aforementioned wake-up frequency domain resources can be predefined by the protocol; or, the bandwidth of the aforementioned wake-up frequency domain resources can also be configured by the network device through other signaling prior to the resource indication information. For example, the network device can configure the bandwidth of the wake-up frequency domain resources to the terminal device through system messages, and subsequently indicate the frequency domain offset of the aforementioned wake-up frequency domain resources through RRC messages or MAC CE.

[0118] In some embodiments, the frequency domain offset is different in different time periods.

[0119] In other words, the offset between the wake-up frequency domain resource mentioned above and the frequency domain bandwidth edge of the downlink BWP where the wake-up frequency domain resource is located can be different in different time periods. The network device can instruct the terminal device to use different frequency domain offsets to determine the wake-up frequency domain resource in different time periods.

[0120] Since the signals transmitted by the initial downlink BWP at different times can be different, their bandwidths and frequency domain positions in the initial downlink BWP can also be different.

[0121] For example, in time period T a Send SSB signal within time period T b The bandwidths of the PDCCH, SSB, and PDCCH signals transmitted within the time period T differ, as do the frequency domain positions of the SSB and PDCCH signals in the initial downlink BWP. b Within this time period T, the frequency offset needs to be determined based on the SSB signal; b Within this timeframe, the frequency offset needs to be determined based on the PDCCH signal. Therefore, during the time period T... a and time period T b Within a network device, the frequency offset indicated by the resource indication information can be different.

[0122] The embodiments of this application further clarify the correlation between the above-mentioned offset and time period, which can improve the accuracy and flexibility of indicating wake-up frequency domain resources in the technical solution of the embodiments of this application.

[0123] Based on the scheme shown in Figure 8 above, please refer to Figure 10, which shows a flowchart of a resource determination method provided in an embodiment of this application. This method can be interactively executed by a terminal device and a network device. The terminal device can be terminal device 120 or terminal device 130 in the network architecture shown in Figure 1, and the network device can be network device 110 in the network architecture shown in Figure 1. The method can include the following steps:

[0124] Step 1001: The network device determines the wake-up frequency domain resource based on the frequency domain offset. The frequency domain offset is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located. The frequency domain offset is determined based on specified information.

[0125] In other words, network devices can determine the wake-up frequency domain resource based on the frequency domain offset, which is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located. This frequency domain offset can be determined by the network device based on specified information.

[0126] Specifically, the frequency domain offset can be the offset between the wake-up frequency domain resource and either side of the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located, or the offset between the two sides of the frequency domain bandwidth edge of the wake-up frequency domain resource and the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located.

[0127] Step 1002: The terminal device determines the wake-up frequency domain resource based on the frequency domain offset. The frequency domain offset is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion BWP where the wake-up frequency domain resource is located. The frequency domain offset is determined based on specified information.

[0128] In other words, the terminal device can determine the wake-up frequency domain resource based on the frequency domain offset. This frequency domain offset is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located. This frequency domain offset can be determined by the terminal device based on specified information.

[0129] Specifically, the frequency domain offset can be the offset between the wake-up frequency domain resource and either side of the frequency domain bandwidth edge of the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located, or the offset between the two sides of the frequency domain bandwidth edge of the wake-up frequency domain resource and the downlink bandwidth portion (BWP) where the wake-up frequency domain resource is located.

[0130] Step 1003: According to the wake-up frequency domain resources, the network device sends a wake-up signal; correspondingly, the terminal device can receive the wake-up signal through the first receiver, and the wake-up signal is used to wake up the second receiver of the terminal device.

[0131] In other words, the network device sends a wake-up signal according to the wake-up frequency domain resource. The terminal device can choose whether to receive the wake-up signal. If it receives it, it receives the wake-up signal through the first receiver according to the wake-up frequency domain resource. The wake-up signal is used to wake up the second receiver of the terminal device.

[0132] In the embodiments of this application, the wake-up signal can be LP-WUS, and the downlink bandwidth portion BWP can be the initial downlink BWP or a non-initial downlink BWP.

[0133] It should be noted that, for the initial downlink BWP, in order to avoid fragmentation of frequency domain resources, the wake-up frequency domain resources of LP-WUS can be set at both ends of the initial downlink BWP.

[0134] In other words, the terminal device can determine whether to carry LP-WUS on one or both sides of the frequency domain resources of the initial downlink BWP based on specified information. This method can avoid the fragmentation of frequency domain resources within the initial downlink BWP and reduce the impact on the resource usage of existing NR signals within the initial downlink BWP.

[0135] In addition to the initial downlink BWP, the method of this application embodiment can also be used if the LP-WUS signal is transmitted in a non-initial downlink BWP. For example, when the UE is in the RRC-connected state, the wake-up frequency domain resource location of the LP-WUS signal can also be determined according to the above method in the downlink BWP configured by the network device through RRC signaling.

[0136] The scheme shown in this application embodiment can determine the frequency domain offset based on specified information, and determine the wake-up frequency domain resources of the wake-up signal based on the frequency domain offset. At the same time, the wake-up frequency domain resources can be located at / close to one or both ends of the downlink BWP, avoiding the fragmentation of the frequency domain resources of the downlink bandwidth portion of the BWP, ensuring that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion of the BWP, not affecting the use of the frequency domain resources of the existing downlink signal, and ensuring the transmission performance of the existing downlink signal.

[0137] In some embodiments, the specified information includes one or more of the following:

[0138] The bandwidth of the downlink BWP where the frequency domain resource is located is activated;

[0139] The position of the SSB in the downlink BWP where the wake-up frequency domain resource is located;

[0140] The position of CORESET's bandwidth within the downlink BWP where the wake-up frequency domain resource is located;

[0141] Time-domain plot of SSB;

[0142] Time-domain plot of PDCCH;

[0143] Reusable patterns for SSB and PDCCH.

[0144] In other words, the specified information can be one or more of the following:

[0145] ① Initial downlink BWP bandwidth

[0146] Based on the bandwidth, terminal devices and / or network devices can calculate the frequency domain offset of wake-up frequency domain resources according to a certain formula.

[0147] The terminal device and / or network device can preset or configure a bandwidth ratio, for example, the bandwidth ratio range can be set to 8%-12%. The frequency domain offset of the wake-up frequency domain resources is the product of the initial downlink BWP bandwidth and the bandwidth ratio. For example: if the initial downlink BWP bandwidth is 20MHz and the preset or configured bandwidth ratio is 10%, then the frequency domain offset of the wake-up frequency domain resources is 20MHz * 10% = 2MHz.

[0148] ②The position of SSB in the initial downlink BWP

[0149] In this embodiment, the frequency domain position of the SSB can be determined from the frequency domain distance of the edge based on the position of the SSB in the initial downlink BWP. Then, the frequency domain offset is determined based on the frequency domain distance. During this process, the frequency domain offset is controlled to ensure that the wake-up frequency domain resources do not overlap with the SSB in the frequency domain.

[0150] The SSB can be located in one of the preset synchronization grids, and its position in the initial downlink BWP can be flexibly set. For example, the SSB occupies a frequency domain bandwidth of 20 resource blocks centered on the synchronization grid. The position of the frequency domain bandwidth occupied by the SSB in the BWP determines the distance of the SSB from the edge of the BWP. This scheme can limit the frequency domain offset of the wake-up frequency domain resources to not be greater than the frequency domain distance of the frequency domain bandwidth occupied by the SSB from the edge of the BWP.

[0151] Furthermore, the frequency offset can be determined based on this frequency domain distance to ensure that the wake-up frequency domain resources do not overlap with the SSB in the frequency domain.

[0152] ③ The position of CORESET bandwidth in the initial downlink BWP

[0153] In this embodiment, the frequency domain position of CORESET can be determined from the frequency domain distance of the edge based on the position of CORESET in the initial downlink BWP, and the frequency domain offset can be determined based on the frequency domain distance to ensure that there is no frequency domain overlap with CORESET.

[0154] The frequency domain resources contained in the CORESET are indicated by the SSB or configured by system messages. The frequency domain location of the CORESET is also relatively flexible in the initial downlink BWP. Using the above scheme, based on the determined position of the CORESET's bandwidth in the initial downlink BWP, the distance of the CORESET from the BWP edge can be determined. This allows us to limit the frequency domain offset of the wake-up frequency domain resources from exceeding the frequency domain distance between the CORESET's occupied frequency domain bandwidth and the BWP edge.

[0155] Furthermore, the frequency offset can be determined based on this frequency domain distance to ensure that the wake-up frequency domain resources do not overlap with CORESET in the frequency domain.

[0156] ④ Time-domain plot of SSB or PDCCH

[0157] In this scheme, the time-domain resources transmitted by the SSB are indicated by system messages, while the listening timing and frequency-domain resources of the PDCCH are determined by the search space information indicated by system messages. Based on the time-domain pattern, different frequency-domain offsets can be determined at different times using this method.

[0158] Among them, the time-domain pattern of PDCCH is the periodic listening time, that is, the time when PDCCH may be sent. At this time, it is necessary to consider the difference in frequency domain offset of wake-up frequency domain resources when there is no PDCCH transmission and when there is PDCCH transmission. Accordingly, the method for calculating frequency domain offset can be different in these two cases.

[0159] Furthermore, during the time periods when there is no PDCCH transmission and when there is PDCCH transmission, the corresponding frequency domain offset needs to be determined separately to ensure that the wake-up frequency domain resources do not overlap with the PDCCH frequency domain.

[0160] ⑤ Multiplexing patterns of SSB and PDCCH

[0161] The multiplexing patterns of SSB and PDCCH can include time division, frequency division, and time-frequency division. Among them, frequency division and time-frequency division need to take into account the bandwidth of SSB and PDCCH after frequency domain superposition and their positions in the initial downlink BWP, determine the frequency domain position of the bandwidth after frequency domain superposition from the edge, determine the frequency domain offset based on the frequency domain distance, and ensure that it does not overlap with the transmission frequency domain of the bandwidth after frequency domain superposition.

[0162] The embodiments of this application further clarify the types of specified information, including one or more of the following: the bandwidth of the downlink BWP where the wake-up frequency domain resource is located, the position of the SSB in the downlink BWP where the wake-up frequency domain resource is located, the position of the CORESET bandwidth in the downlink BWP where the wake-up frequency domain resource is located, the time domain pattern of the SSB, the time domain pattern of the PDCCH, and the multiplexing time domain pattern of the SSB and PDCCH, which can improve the flexibility of the technical solution of the embodiments of this application.

[0163] In other words, the scheme shown in the embodiments of this application can determine the frequency domain offset of the frequency domain resources of LP-WUS from the frequency domain edge of the initial downlink BWP according to preset rules; the preset rules can determine the frequency domain offset based on one or more of the above information.

[0164] In some embodiments, the frequency domain offset is associated with the frequency domain position of the SSB in the downlink BWP where the wake-up frequency domain resource is located; and the wake-up frequency domain resource does not overlap with the frequency domain resource of the SSB in the downlink BWP.

[0165] In other words, the aforementioned frequency domain offset is related to the frequency domain position of the SSB in the downlink BWP where the wake-up frequency domain resource is located.

[0166] The frequency domain offset is the offset between the wake-up frequency domain resource and the edge of the frequency domain bandwidth of the downlink bandwidth portion BWP where the wake-up frequency domain resource is located. It does not overlap with the frequency domain resources of SSB in the downlink BWP, so as to avoid fragmentation of the frequency domain resources of the downlink bandwidth portion BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion BWP, not affect the use of the frequency domain resources of the existing SSB signal, and ensure the transmission performance of the SSB signal.

[0167] In some embodiments, the frequency domain offset is associated with the frequency domain position of the PDCCH in the downlink BWP where the wake-up frequency domain resource is located; and the wake-up frequency domain resource does not overlap with the frequency domain resource of the PDCCH in the downlink BWP.

[0168] In other words, the aforementioned frequency domain offset is related to the frequency domain position of the PDCCH in the downlink BWP where the wake-up frequency domain resource is located.

[0169] The frequency domain offset is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion BWP where the wake-up frequency domain resource is located. It does not overlap with the frequency domain resources of PDCCH in the downlink BWP, so as to avoid fragmentation of the frequency domain resources of the downlink bandwidth portion BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion BWP, and not affect the use of the frequency domain resources of the existing PDCCH signal, thus ensuring the transmission performance of the PDCCH signal.

[0170] In some embodiments, the frequency domain offset is associated with the frequency domain position of CORESET in the downlink BWP where the wake-up frequency domain resource is located; and the wake-up frequency domain resource does not overlap with the frequency domain resource of CORESET in the downlink BWP.

[0171] In other words, the aforementioned frequency domain offset is related to the frequency domain position of CORESET in the downlink BWP where the wake-up frequency domain resource is located.

[0172] The frequency domain offset is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion BWP where the wake-up frequency domain resource is located. It does not overlap with the frequency domain resources of CORESET in the downlink BWP, so as to avoid fragmentation of the frequency domain resources of the downlink bandwidth portion BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion BWP, and not affect the use of the frequency domain resources of the existing CORESET signal, thus ensuring the transmission performance of the CORESET signal.

[0173] In some embodiments, the frequency domain offset is associated with the bandwidth of the downlink BWP where the wake-up frequency domain resource is located.

[0174] In other words, the frequency domain offset mentioned above is related to the bandwidth of the downlink BWP where the wake-up frequency domain resource is located, and the frequency domain offset is the offset between the wake-up frequency domain resource and the edge of the frequency domain bandwidth of the downlink bandwidth portion BWP where the wake-up frequency domain resource is located, so as to avoid the fragmentation of the frequency domain resources of the downlink bandwidth portion BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion BWP, not affect the use of the frequency domain resources of the existing signal, and ensure the transmission performance of the existing signal.

[0175] Specifically, based on the bandwidth of the initial downlink BWP, for example, if the initial downlink BWP width is 40MHz, the offset of the wake-up frequency domain resource can be calculated as 4MHz according to a certain formula.

[0176] In some embodiments, the frequency domain offset is associated with the location of other signals transmitted in the downlink BWP where the wake-up frequency domain resource is located; other signals are signals other than the wake-up signal.

[0177] In other words, the frequency domain offset mentioned above is related to the position of other signals transmitted in the downlink BWP where the wake-up frequency domain resource is located. These other signals refer to signals other than the wake-up signal, such as SSB, PDCCH, PDSCH, or paging signal.

[0178] In other words, the frequency domain offset is the offset between the wake-up frequency domain resource and the edge of the frequency domain bandwidth of the downlink bandwidth portion BWP where the wake-up frequency domain resource is located. It does not overlap with the position of other signals transmitted in the downlink BWP where the wake-up frequency domain resource is located, so as to avoid fragmentation of the frequency domain resources of the downlink bandwidth portion BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion BWP, not affect the use of the frequency domain resources of other existing signals, and ensure the transmission performance of other signals.

[0179] Specifically, the frequency domain offset can be the offset of the wake-up frequency domain resource from the high / low frequency edge. The offset of the wake-up frequency domain resource from the high frequency edge and the offset of the wake-up frequency domain resource from the low frequency edge can be the same or different.

[0180] Specifically, the frequency domain offset can be the offset of the start / end point of the wake-up frequency domain resource from the high / low frequency edge. The offset of the start / end point of the wake-up frequency domain resource from the high frequency edge and the offset of the start / end point of the wake-up frequency domain resource from the low frequency edge can be the same or different.

[0181] For example, the frequency domain offset of LP-WUS's wake-up frequency domain resources from the low-frequency edge is... The frequency domain offset of LP-WUS's wake-up frequency domain resources from the high-frequency edge is: Figure 11 shows a schematic diagram of the wake-up frequency domain resource location of an LP-WUS according to an embodiment of this application. As shown in Figure 11, the frequency domain resources gradually increase from bottom to top, and the starting frequency of the wake-up frequency domain resources is lower than the ending frequency. At this time, the frequency domain offsets of the starting point of the LP-WUS wake-up frequency domain resources from the low frequency edge and the high frequency edge are respectively... and Therefore, the starting points of LP-WUS wake-up frequency domain resources within BWP are respectively located at... and Furthermore, the frequency domain resources between the wake-up frequency domain resources of the two LP-WUS segments are used to transmit PDCCH, PDSCH and / or SSB.

[0182] In some embodiments, the frequency domain offset is associated with the multiplexing pattern of SSB and PDCCH in the downlink BWP.

[0183] In other words, the frequency domain offset mentioned above is related to the multiplexing pattern of SSB and PDCCH in the downlink BWP. The multiplexing pattern of SSB and PDCCH can include time division, frequency division and time-frequency division.

[0184] It should be noted that the frequency domain offset is the offset between the wake-up frequency domain resource and the edge of the frequency domain bandwidth of the downlink bandwidth portion BWP where the wake-up frequency domain resource is located. It does not overlap with the multiplexing pattern of SSB and PDCCH in the downlink BWP, so as to avoid fragmentation of the frequency domain resources of the downlink bandwidth portion BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion BWP, and not affect the use of the frequency domain resources of the existing SSB and PDCCH signals, thus ensuring the transmission performance of SSB and PDCCH signals.

[0185] In some embodiments, when the signals transmitted in the downlink BWP include SSB and PDCCH during the first time period indicated by the multiplexing pattern, the frequency domain offset during the first time period is associated with the frequency domain resources of SSB and PDCCH during the first time period; and the wake-up frequency domain resources during the first time period do not overlap with the frequency domain resources of SSB and PDCCH during the first time period.

[0186] In other words, in the time-division case, it is necessary to consider the position of the frequency domain resources of SSB and PDCCH in the initial downlink BWP within the same time period, and within the same time period, the frequency domain offset does not overlap with the frequency domain resources of SSB and PDCCH, so as to avoid fragmentation of the frequency domain resources of the downlink bandwidth portion of the BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion of the BWP, not affect the use of the frequency domain resources of the existing SSB and PDCCH signals, and ensure the transmission performance of SSB and PDCCH signals.

[0187] Taking the multiplexing pattern 1 of SSB and PDCCH as an example, the time-division multiplexing of SSB and PDCCH results in different distances from the frequency domain resources of SSB and PDCCH to the frequency domain bandwidth edge of the initial downlink BWP due to the different bandwidth and frequency domain position of their CORESETs at different times. Specifically, the time domain resources transmitted by SSB are indicated by system messages, while the listening timing and frequency domain resources of PDCCH are determined by the search space information indicated by system messages.

[0188] Figure 12 illustrates another schematic diagram of the wake-up frequency domain resource location of LP-WUS according to an embodiment of this application. As shown in Figure 12, the frequency domain offset of the LP-WUS resource from the frequency domain bandwidth edge of the initial downlink BWP is different during the transmission time of SSB and the transmission time of PDCCH. The time interval T1 includes the transmission time of SSB, and within T1, the wake-up frequency domain resources of LP-WUS do not overlap with the SSB frequency domain resources. The time interval T2 includes the transmission time of PDCCH, and within T2, the wake-up frequency domain resources of LP-WUS do not overlap with the PDCCH frequency domain resources. The wake-up frequency domain resources of LP-WUS can be different or the same within T1 and T2.

[0189] In other words, the frequency domain offset can be different at different times. For example, since the signals transmitted by the initial downlink BWP can be different at different times, their bandwidth and frequency domain position in the initial downlink BWP are also different. Taking the multiplexing pattern of SSB and PDCCH as an example, the time-division multiplexing of SSB and PDCCH results in different distances of their frequency domain resources from the edge of the initial downlink BWP at different times due to the different bandwidth and frequency domain position of the CORESET of SSB and PDCCH. Among them, the time domain resources transmitted by SSB can be indicated by system messages, and the listening time and frequency domain resources of PDCCH can be determined by the search space information indicated by system messages. As shown in Figure 12, the frequency domain offset of WUS resources from the edge of the initial downlink BWP is different at the transmission time of SSB and the transmission time of PDCCH.

[0190] In some embodiments, where the multiplexing pattern indicates the frequency domain positions of the SSB and PDCCH in the downlink BWP, the frequency domain offset is associated with the frequency domain positions of the SSB and PDCCH in the downlink BWP, and the wake-up frequency domain resources do not overlap with the frequency domain resources of the SSB and PDCCH.

[0191] In other words, under frequency division and time-frequency division, it is necessary to consider the bandwidth of the SSB and PDCCH after frequency domain superposition and their positions in the initial downlink BWP. The frequency domain position of the bandwidth after frequency domain superposition is determined from the frequency domain distance of the edge. The frequency domain offset is determined based on the frequency domain distance to ensure that it does not overlap with the transmission frequency domain of the bandwidth after frequency domain superposition. This avoids the fragmentation of the frequency domain resources of the downlink bandwidth portion of the BWP, ensures that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion of the BWP, does not affect the use of the frequency domain resources of the existing SSB and PDCCH signals, and ensures the transmission performance of the SSB and PDCCH signals.

[0192] Taking the SSB and PDCCH multiplexing pattern 2 as an example, in the frequency division multiplexing of SSB and PDCCH, the network device transmits SSB and PDCCH on different bandwidths within the same time interval. Figure 13 shows another schematic diagram of the wake-up frequency domain resource location of LP-WUS according to an embodiment of this application. As shown in Figure 13, when the multiplexing pattern indicates the frequency domain position of SSB and PDCCH in the downlink BWP, the frequency domain offset of LP-WUS resources from the edge of the frequency domain bandwidth of the initial downlink BWP can ensure that the wake-up frequency domain resources of LP-WUS do not overlap with the bandwidth after the frequency domain superposition of SSB and PDCCH.

[0193] In some embodiments, the frequency domain offset is associated with a first time-domain pattern of the SSB in the downlink BWP.

[0194] In other words, the aforementioned frequency domain offset is related to the time domain pattern of the SSB in the downlink BWP.

[0195] It should be noted that the frequency domain offset is the offset between the wake-up frequency domain resource and the edge of the frequency domain bandwidth of the downlink bandwidth portion BWP where the wake-up frequency domain resource is located, and it does not overlap with the time domain pattern of the SSB in the downlink BWP, so as to avoid fragmentation of the frequency domain resources of the downlink bandwidth portion BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion BWP, not affect the use of the frequency domain resources of the existing SSB signal, and ensure the transmission performance of the SSB signal.

[0196] In some embodiments, where the signal transmitted in the downlink BWP includes an SSB during the second time period indicated by the first time-domain pattern,

[0197] The frequency domain offset within the second time period is associated with the frequency domain resources of the SSB within the second time period; and the wake-up frequency domain resources within the second time period do not overlap with the frequency domain resources of the SSB within the second time period.

[0198] In other words, when the signal transmitted in the downlink BWP includes SSB during the second time period indicated by the first time-domain pattern, the frequency domain offset is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion of the BWP where the wake-up frequency domain resource is located. It does not overlap with the frequency domain resources of the SSB during the second time period, so as to avoid fragmentation of the frequency domain resources of the downlink bandwidth portion of the BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion of the BWP, not affect the use of the frequency domain resources of the existing SSB signal, and ensure the transmission performance of the SSB signal.

[0199] Taking the first time-domain pattern of SSB as an example, Figure 14 shows another schematic diagram of the wake-up frequency domain resource location of LP-WUS involved in the embodiment of this application. As shown in Figure 14, the first time-domain pattern indicates that the initial downlink BWP contains SSB during the second time period, and the frequency domain resources where SSB is located are different at different times during the second time period. During the entire second time period, the frequency domain offset of LP-WUS resources from the frequency domain bandwidth edge of the initial downlink BWP can ensure that LP-WUS resources do not overlap with the frequency domain resources where SSB is located during the entire second time period.

[0200] In some embodiments, the frequency domain offset is associated with a second time-domain pattern of the PDCCH in the downlink BWP.

[0201] In other words, the aforementioned frequency domain offset is related to the time domain pattern of the PDCCH in the downlink BWP.

[0202] It should be noted that the frequency domain offset is the offset between the wake-up frequency domain resource and the edge of the frequency domain bandwidth of the downlink bandwidth portion BWP where the wake-up frequency domain resource is located, and it does not overlap with the time domain pattern of the PDCCH in the downlink BWP, so as to avoid fragmentation of the frequency domain resources of the downlink bandwidth portion BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion BWP, not affect the use of the frequency domain resources of the existing PDCCH signal, and ensure the transmission performance of the PDCCH signal.

[0203] In some embodiments, when the signal transmitted in the downlink BWP includes PDCCH during the third time period indicated by the second time-domain pattern, the frequency domain offset during the third time period is associated with the frequency domain resources of PDCCH during the third time period; and the wake-up frequency domain resources during the third time period do not overlap with the frequency domain resources of PDCCH during the third time period.

[0204] In other words, when the signal transmitted in the downlink BWP includes PDCCH during the third time period indicated by the second time-domain pattern, the frequency domain offset is the offset between the wake-up frequency domain resource and the frequency domain bandwidth edge of the downlink bandwidth portion of the BWP where the wake-up frequency domain resource is located. Furthermore, the frequency domain resources of PDCCH in the third time period do not overlap, in order to avoid fragmentation of the frequency domain resources of the downlink bandwidth portion of the BWP, ensure that there is as large a continuous bandwidth as possible in the middle of the downlink bandwidth portion of the BWP, not affect the use of the frequency domain resources of the existing PDCCH signal, and ensure the transmission performance of the PDCCH signal.

[0205] Taking the second time-domain pattern of PDCCH as an example, Figure 15 shows another schematic diagram of the wake-up frequency domain resource location of LP-WUS involved in the embodiment of this application. As shown in Figure 15, the second time-domain pattern indicates that the initial downlink BWP contains PDCCH in the third time period, and the frequency domain resources where PDCCH is located are different at different times in the third time period. In the entire third time period, the frequency domain offset of LP-WUS resources from the frequency domain bandwidth edge of the initial downlink BWP can ensure that LP-WUS resources do not overlap with the frequency domain resources where PDCCH is located in the entire third time period.
