If the name of the core network equipment mentioned in the embodiments of this application changes in subsequent protocol versions (e.g., 6G), it is also within the scope of protection of this application.

[0074] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0075] A low-power receiver, also known as an LP-WUR or near-zero power wake-up radio (AZP-WUR), operates on the principle that the receiver comprises a first module and a second module, as shown in Figure 2. The first module is the main communication module, used for transmitting and receiving mobile communication data. The second module is a low-power receiver module (also called a low-power wake-up receiver module), used to receive the wake-up signal. In power-saving mode, the terminal activates the low-power receiver module to listen for LP-WUR and disables the main communication module. When downlink data arrives, the network sends a wake-up signal to the terminal. Upon detecting the wake-up signal through the low-power receiver module, the terminal triggers the main communication module to switch from off to on via a series of checks. At this time, the low-power receiver module transitions from an active state to a shutdown or sleep state. The low-power receiver module can be continuously or intermittently activated, and when activated, it can receive the low-power wake-up signal.

[0076] To reduce receiving activity in standby mode and effectively shut down the radio frequency (RF) and modem modules, thereby significantly reducing power consumption during communication reception, this can be achieved by introducing a near-zero power receiver into the terminal's receiver module. This near-zero power receiver eliminates the need for complex RF module signal detection (such as amplification, filtering, quantization, etc.) and modem signal processing, performing only passive matched filtering and low-power signal processing.

[0077] On the base station side, by triggering a wake-up signal on demand, the receiver with near-zero power can be activated, thereby triggering a series of processes inside the terminal, such as turning on the radio frequency transceiver and baseband processing modules.

[0078] These wake-up signals are typically simple on-off keying signals, the time-domain representation of which is shown in Figure 3. The receiver can detect the wake-up signal through simple energy detection and subsequent sequence detection and recognition. Furthermore, while the terminal activates its low-power wake-up receiver to receive the wake-up signal, the main receiver module can maintain a low power consumption level, thus saving power by receiving the wake-up signal. The reception of low-power wake-up signals can be applied to terminals in Radio Resource Control (RRC) idle / inactive states, as well as terminals in RRC connected states, thereby achieving terminal energy saving.

[0079] In communication systems, to adapt to different coverage targets, the original information bits need to be expanded through encoding, rate matching, and other methods to occupy more resources and achieve suitable coverage. For information bits with a length greater than 2, Reed Muller (RM) encoding can be used, the principle of which is as follows:

[0080] When the length of the input information bits is K, 3≤K≤11, the encoding method is as follows: Where i = 0, 1, ..., N-1, N = 32, M i,k The sequence is shown below:

[0081] Due to power limitations, OOK receivers require very low computational complexity at the receiver end. Therefore, based on the computational complexity at the receiver end, the detection methods of OOK receivers can be divided into single sequence detection and maximum likelihood detection (ML detection).

[0082] ML detection correlates the received signal with all candidate codepoints, then determines the received codepoint based on the correlation value, and compares the maximum correlation value with a detection threshold. After passing the detection threshold, the detected codepoint is compared with the target codepoint. If they match, the detection is successful. This detection method has high computational complexity, but it can effectively guarantee the performance of the false alarm rate (FAR) from noise and the FAR from non-target codepoints through the two steps of detection threshold and target codepoint comparison. It also requires only a very low detection threshold (determined by the noise level) and has good missed detection rate (MDR) performance.

[0083] For single sequence detection, the receiver only needs to correlate the received signal with the target codepoint and then compare the correlation value with the detection threshold. If the detection threshold is passed, the detection is successful. This detection method has low computational complexity. However, for FAR (First-Ahead Ranging), the detection threshold must be determined to guarantee performance, especially for FAR from non-target codepoints. Since the non-target codepoint and target codepoint are not orthogonal sequences, the Hamming distance between them is determined by the rules of RM (Random Access Detection) coding. Therefore, the correlation value between the non-target codepoint and the target codepoint will be relatively high. To ensure FAR performance, a higher detection threshold also needs to be determined. However, this will lead to a decrease in MDR (Mean-Depth Detection) performance. When the output bits of the RM code are 32 bits, the Hamming distance between the output bits of the RM code can reach half the length of the output bits, which is 16 bits. This can guarantee good FAR and MDR performance. However, when the output bits are less than 32 bits, the Hamming distance between the RM code bits obtained by rate matching will be less than half the length of the output bits, resulting in a higher detection threshold and thus worsening FAR and MDR performance.

[0084] To address the aforementioned problems, this invention proposes a communication method that, based on the length of the indication information or information bits, employs an appropriate encoding or mapping method to ensure that a low-computational-complexity OOK receiver (a receiver employing single sequence detection) exhibits good FAR and MDR performance, thereby improving the detection performance of the OOK receiver.

[0085] The communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0086] This application provides a communication method, as shown in FIG4, including:

[0087] Step 101: The network-side device acquires the first information carried by the wake-up signal;

[0088] Step 102: The network-side device maps the first information into a first bit sequence according to the second information. The first bit sequence is used to generate the wake-up signal. The second information includes at least one of the following: the length of the first bit sequence, first indication information, and the bit length of the first information.

[0089] In the embodiments of this application, the first bit sequence can be generated using the first information by adopting an appropriate encoding method or mapping method according to the length of the first bit sequence, the first indication information and / or the bit length of the first information, thereby generating a wake-up signal. This can ensure that the OOK receiver with low computational complexity has good FAR performance and MDR performance, and improve the detection performance of the OOK receiver.

[0090] In some embodiments, the network-side device maps the first information to a first bit sequence based on the second information in any of the following ways:

[0091] The network-side device encodes the first information to generate the first bit sequence;

[0092] The network-side device maps the first information to a first bit sequence group to obtain the first bit sequence.

[0093] In this embodiment, the network-side device can generate the first bit sequence according to the second information using an appropriate encoding or mapping method, which can ensure that the OOK receiver with low computational complexity has good FAR and MDR performance and improve the detection performance of the OOK receiver.

[0094] In some embodiments, the length of the first bit sequence can be directly configured by the network-side device.

[0095] Alternatively, the length of the first bit sequence can be indirectly calculated from the time-domain resources (MO duration and the number of available symbols in the MO), rate, and Manchester coding rate configured by the network-side device. For example, if the configured time-domain resources are 14 symbols, the rate is 2 (one symbol transmits 2 chips), and the Manchester coding rate is 1 / 2 (meaning one bit in the first bit sequence will be encoded as 2 chips), then the length of the first bit sequence is: number of symbols * rate * Manchester coding rate = 14 * 2 * 1 / 2 = 28 bits.

[0096] Alternatively, the network-side device can configure the bit length of the first information and the coding rate used to map the first information to the first bit sequence, and then calculate the length of the first bit sequence. For example, if the configured bit length of the first information is 5 bits, RM code is used, and the coding rate used to map the first information to the first bit sequence is r = 5 / 20, then the length of the first bit sequence is 5 / r = 20 bits.

[0097] In some embodiments, the network-side device encodes the first information to generate the first bit sequence, including:

[0098] The network-side device encodes the first information using at least one of the following encoding methods, and generates the first bit sequence based on the encoded first information:

[0099] Reed-Muller encoding, simplex encoding, and repetition encoding.

[0100] In some embodiments, generating the first bit sequence based on the encoded first information includes:

[0101] Perform at least one of the following operations on the encoded first information to obtain the first bit sequence:

[0102] Sequence inversion, rate matching, repetition.

[0103] In this embodiment, if the bit length of the encoded first information is different from the length of the first bit sequence contained in the second information, a first bit sequence with the same length as the first bit sequence contained in the second information can be generated through operations such as sequence inversion, rate matching, and / or repetition. This can ensure that the OOK receiver with low computational complexity has good FAR and MDR performance, and improve the detection performance of the OOK receiver.

[0104] In some embodiments, the bit length of the encoded first information is L, the length of the first bit sequence indicated by the second information is M, and L is greater than M. Rate matching is performed on the encoded first information to obtain the first bit sequence, including any of the following methods:

[0105] The first bit sequence is obtained by extracting the first M bits from the encoded first information;

[0106] The first bit sequence is obtained by extracting the last M bits from the encoded first information;

[0107] The first bit sequence is obtained by extracting the middle M bits from the encoded first information;

[0108] The first bit sequence is obtained by extracting M bits from the encoded first information according to preset rules.

[0109] In this embodiment, when the length of the first bit sequence differs from the bit length of the encoded first information, rate matching can be performed on the encoded first information to obtain the first bit sequence. For example, if the length of the first bit sequence is 20 and the length of the first information after RM encoding is 32, 20 bits can be sequentially extracted from the head of the 32-bit encoded first information to obtain the first bit sequence, or 20 bits can be extracted from the tail of the 32-bit encoded first information in reverse order to obtain the first bit sequence, or 20 bits can be extracted from the middle position of the 32-bit encoded first information to obtain the first bit sequence (for example, extracting 20 bits starting from 32-20+1=13 bits); or 20 bits can be extracted from the 32-bit encoded first information according to a specific pattern to obtain the first bit sequence, where the pattern is indicated by the network-side device or predefined by the protocol.

[0110] In this embodiment, if the bit length L of the encoded first information is different from the length M of the first bit sequence contained in the second information, a first bit sequence of length M can be generated by rate matching. This can ensure that the OOK receiver with low computational complexity has good FAR and MDR performance, and improve the detection performance of the OOK receiver.

[0111] In some embodiments, the method for rate matching of the encoded first information is determined by at least one of the following: system information indication, protocol predefined, bit length of the first information, and length of the first bit sequence. For example, when the length of the first bit sequence is less than or equal to 16, the first bit sequence can be extracted sequentially from the beginning of the encoded first information; when the length of the first bit sequence is greater than 16, the first bit sequence can be extracted from the end or middle of the encoded first information.

[0112] In some embodiments, the first indication information explicitly or implicitly indicates the method of mapping the first information to the first bit sequence. In this embodiment, the first indication information can indicate a suitable encoding or mapping method to generate the first bit sequence, which can ensure that the OOK receiver with low computational complexity has good FAR and MDR performance, thereby improving the detection performance of the OOK receiver.

[0113] In some embodiments, when the second information includes the first indication information, the network-side device maps the first information to a first bit sequence group, or encodes the first information using an encoding method other than Reed-Muller encoding to obtain the first bit sequence;

[0114] If the second information does not include the first indication information, the network-side device performs Reed-Muller encoding on the first information according to the second information to generate the first bit sequence.

[0115] In this embodiment, the first indication information can indicate a suitable encoding or mapping method to generate the first bit sequence, which can ensure that the OOK receiver with low computational complexity has good FAR and MDR performance and improve the detection performance of the OOK receiver.

[0116] In some embodiments, the network-side device mapping the first information into a first bit sequence based on the second information includes:

[0117] When the bit length of the first information is less than or equal to a first preset value, the network-side device repeatedly encodes the first information to generate the first bit sequence;

[0118] If the length of the first bit sequence is greater than or equal to a second preset value, the network-side device performs Reed-Muller encoding on the first information to generate the first bit sequence.

[0119] The values ​​of the first and second preset values ​​can be pre-configured or defined by the protocol. For example, when the bit length of the first information is 1 or 2, the first information can be mapped to the target bit sequence (i.e., the first bit sequence) using repetitive encoding. When the bit length of the first information is 3 to 11 and the length of the first bit sequence is 32, the first information can be mapped to the target bit sequence using RM encoding; or, even when the length of the first bit sequence is not 32, it is still possible to instruct the use of RM encoding to map the first information to the target bit sequence.

[0120] In this embodiment, the bit length of the first information and the length of the first bit sequence can indicate a suitable encoding method to generate the first bit sequence, which can ensure that the OOK receiver with low computational complexity has good FAR and MDR performance and improve the detection performance of the OOK receiver.

[0121] In some embodiments, the network-side device mapping the first information to a first bit sequence based on the second information includes any of the following:

[0122] The length of the first bit sequence is 2 n At that time, using the Hadamard sequence to generate 2 n *2 n The first bit sequence group of dimension, the first information with a bit length less than or equal to n is directly mapped to the first bit sequence group to obtain the first bit sequence, where n is a positive integer greater than 1;

[0123] The length of the first bit sequence is 2 n At that time, using the Hadamard sequence to generate 2 n+1 *2 n The first bit sequence group of dimension is directly mapped to the first bit sequence group, where the bit length is less than or equal to n+1, to obtain the first bit sequence, where n is a positive integer greater than 1.

[0124] For example, when the length of the first bit sequence is 8, an 8x8 dimensional Hadamard sequence group or a 16x8 dimensional Hadamard sequence group can be generated. An 8x8 dimensional Hadamard sequence group is shown below:

[0125] The first piece of information with a bit length less than or equal to 3 bits can be mapped to an 8x8 dimensional sequence group. For example, if the first piece of information is [0 0 0], the corresponding sequence index is 1, and the target bit sequence is retrieved from the 8x8 dimensional sequence group based on the sequence index; if the first piece of information is [1 1 1], the corresponding sequence index is 8, and the target bit sequence is retrieved from the 8x8 dimensional sequence group based on the sequence index. When the bit length of the first piece of information is 3 bits, the sequence index corresponding to the first piece of information can be mapped one-to-one with the bit sequences in the 8x8 dimensional sequence group.

[0126] When the bit length of the first information is 4 bits, there are 16 sequence indices corresponding to the first information. However, the 8*8 dimension sequence group only has 8 bit sequences. The 8*8 dimension sequence group can be transformed into a 16*8 dimension sequence group through inversion and concatenation operations. Specifically,

[0127] Inverting H1 yields the sequence group.

[0128] Concatenating H1 and H2 yields a 16*8 dimensional sequence group. The target bit sequence can then be extracted from this 16*8 dimensional sequence group based on the sequence index corresponding to the first piece of information.

[0129] Similarly, when the length of the first bit sequence is 16, a 16*16 dimensional Hadamard sequence group or a 32*16 dimensional Hadamard sequence group can be generated. The 16*16 dimensional Hadamard sequence group is shown below:

[0130] The first piece of information with a bit length less than or equal to 4 bits can be mapped to a 16*16 dimensional sequence group. For example, if the first piece of information is [0 0 0 0], the corresponding sequence index is 1, and the target bit sequence is retrieved from the 16*16 dimensional sequence group based on the sequence index; if the first piece of information is [1 1 1 1], the corresponding sequence index is 16, and the target bit sequence is retrieved from the 16*16 dimensional sequence group based on the sequence index. When the bit length of the first piece of information is 4 bits, the sequence index corresponding to the first piece of information can be mapped one-to-one with the bit sequences in the 16*16 dimensional sequence group.

[0131] When the bit length of the first information is 5 bits, there are 32 sequence indices corresponding to the first information. However, the 16*16 dimension sequence group only contains 16 bit sequences. The 16*16 dimension sequence group can be transformed into a 32*16 dimension sequence group through inversion and concatenation operations. Specifically, the sequence group is obtained by inverting H1:

[0132] Concatenating H1 and H2 yields a 32*16 dimensional sequence group. The target bit sequence can then be extracted from this 32*16 dimensional sequence group based on the sequence index corresponding to the first piece of information.

[0133] In this embodiment, the length of the first bit sequence can indicate a suitable mapping method for generating the first bit sequence, which can ensure that the OOK receiver with low computational complexity has good FAR and MDR performance, thereby improving the detection performance of the OOK receiver.

[0134] In some embodiments, the second information may be network-side device configuration or protocol predefined.

[0135] This application provides a communication method, as shown in Figure 5, including:

[0136] Step 201: When the terminal detects a wake-up signal, the terminal begins listening to the physical channel at a first moment. The first moment is determined based on a first time interval, and the start time of the first time interval is at least one of the following:

[0137] The end time of N repeated transmissions of the overlaid OFDM sequence of the wake-up signal monitored by the terminal, where N is a positive integer;

[0138] The end time of the wake-up signal listening time (MO) at which the wake-up signal is detected by the terminal;

[0139] The end time of the wake-up signal listening window or the set of wake-up signals MO in which the wake-up signal is detected by the terminal;

[0140] The specific location in the wake-up signal transmission corresponding to the wake-up signal detected by the terminal.

[0141] In the embodiments of this application, for a specific terminal, such as a terminal with the ability to detect low-power signals based on OFDM waveforms, physical channel monitoring can be started at an appropriate first moment, without having to wait until the entire WUS transmission is completed, which can reduce the latency of physical channel monitoring.

[0142] In some embodiments, the first moment is the end moment of the first time interval. More specifically, it is the end moment of the time unit containing the end moment of the first time interval.

[0143] Furthermore, the physical signals include the Physical Downlink Control Channel (PDCCH) and the Physical Downlink Shared Channel (PDSCH). Optionally, the Physical Downlink Control Channel includes the Paging PDCCH.

[0144] Furthermore, N is the maximum number of repeated transmissions configured on the network side, or N is the number of repeated transmissions of the wake-up signal actually sent by the network side, or N is the number of repetitions required for the terminal to successfully detect the wake-up signal.

[0145] Furthermore, the WUS listening window is a WUS listening window within a WUS cycle, and the WUS MOs in the WUS MO set are for the same PDCCH listening. For example, the WUS MOs in the WUS MO set are associated with the same PDCCH listening timer. The terminal listens for the PDCCH during the execution of the PDCCH listening timer.

[0146] In some embodiments, the specific position is the end position of the Kth on / off key high-level chip OOK ON in the wake-up signal transmission, where K is a positive integer.

[0147] In some embodiments, K is the number of OOK ON chips required for M repeated transmissions of the overlaid OFDM sequence.

[0148] In some embodiments, the start time of the first time interval is associated with the type of the terminal. This allows for selecting an appropriate first time to begin physical channel monitoring based on the terminal type, eliminating the need to wait until the entire WUS transmission is complete and reducing physical channel monitoring latency.

[0149] In some embodiments, when the terminal is a terminal capable of detecting low-power signals based on OFDM waveforms, the start time of the first time interval includes one or more.

[0150] In some embodiments, when the terminal is a terminal capable of detecting low-power signals based on OFDM waveforms, the start time of the first time interval includes:

[0151] The end time of N repeated transmissions of the overlaid OFDM sequence of the wake-up signal monitored by the terminal, or a specific position in the transmission of the wake-up signal corresponding to the wake-up signal monitored by the terminal.

[0152] The end time of the wake-up signal MO in which the wake-up signal is located, or the end time of the wake-up signal listening window or the set of wake-up signals MO in which the wake-up signal is located, as monitored by the terminal.

[0153] In the case that the terminal is a terminal with the ability to detect low-power signals based on OFDM waveforms, the start time of the first time interval can be multiple, and different types of physical channels can be monitored at different start times.

[0154] In some embodiments, when the terminal is a terminal capable of detecting low-power signals based on OOK waveforms, the start time of the first time interval is any one of the following:

[0155] The end time of the wake-up signal MO, which is the wake-up signal monitored by the terminal;

[0156] The end time of the wake-up signal listening window or the set of wake-up signals MO that the terminal listens to.

[0157] In one specific embodiment, in the connected state, a terminal is a terminal with low-power signal detection capability based on Orthogonal Frequency Division Multiplexing (OFDM) waveforms. Upon receiving a wake-up signal, the terminal resumes or begins PDCCH monitoring at the first instant. The LP-WUS waveform is an OOK superimposed overlaid OFDM sequence. The network-side configured overlaid OFDM sequence has eight sequences, each capable of carrying 3 bits of information. The LP-WUS information bits are 5 bits. In some embodiments, as shown in Figure 8, the network-side configuration or protocol stipulates that the start position of the first time interval or the reference point of the first time interval is the end position of the fourth OOK ON chip in the LP-WUS.

[0158] In this embodiment, a terminal with an OFDM low-power receiver does not need to wait for the entire WUS transmission to finish before starting PDCCH listening (in Figure 8, PDCCH listening is achieved by starting a PDCCH listening timer, during which the terminal performs PDCCH listening). This further reduces the PDCCH listening latency for terminals with OFDM low-power receivers.

[0159] In another specific embodiment, in the connected state, one type of terminal is a terminal with low-power signal detection capability based on OFDM waveform. Upon receiving a wake-up signal, the terminal resumes or begins PDCCH monitoring at the first instant. The start position or reference point of the first time interval is the end time of N repeated transmissions of the overlaid OFDM sequence of the wake-up signal that the terminal has detected. N can be the maximum number of repeated transmissions configured by the network side, or N can be the number of repeated transmissions of the wake-up signal actually sent by the network side. For example, the network side sends N = 3 repeated transmissions of the overlaid OFDM sequence. After receiving these 3 repeated transmissions of the overlaid OFDM sequence, the terminal starts the first time interval and resumes PDCCH monitoring after the first time interval.

[0160] In another embodiment, the physical channel is the paging PDCCH. In 6G, the network side can flexibly configure the LP-WUS monitoring resources. In addition, the network side can configure additional or dynamically allocated paging occupancy (PO) for the paged or woken-up terminal, so that the terminal can start listening for paging at the first moment based on the first time interval given in the above embodiment, without waiting for the paging occupancy determined by the terminal ID, thereby reducing the latency of listening for paging.

[0161] In the RRC idle / inactive state, when the terminal detects the wake-up signal, the terminal begins paging the PDCCH at the first instant; the first instant can be determined based on a first time interval, the starting position of which is:

[0162] The terminal detects the end time of N repeated transmissions of the overlaid OFDM sequence of the wake-up signal, or the terminal detects the end time of the WUS MO where the wake-up signal is located, or...

[0163] The terminal detects the end time of the WUS listening window or the WUS MO set where the wake-up signal is located, or

[0164] The specific position in the wake-up signal transmission corresponding to the wake-up signal detected by the terminal. For example, the end position of the Kth OOK ON chip in WUS. Optionally, K is the maximum number of OOK ON chips that can carry an overlaid OFDM sequence.

[0165] It should be noted that the first moment is the end of the first time interval or the end of the time unit in which the end moment is located.

[0166] The value and definition of the first time interval in the RRC idle / inactive state can differ from those in the connected state. In the RRC idle / inactive state, the first time interval is greater than or equal to the wake-up latency required for the terminal to apply LP-WUS in the RRC idle / inactive state.

[0167] In some embodiments, when the terminal is a first type of terminal (the first type of terminal is a terminal with the ability to detect low-power signals based on OFDM waveforms), the starting position of the first time interval associated with the first type of terminal includes a starting position 1 and a starting position 2. The starting position 1 is the end time when the terminal listens to the MO where the wake-up signal is located, or the end time when the terminal listens to the WUS listening window or WUS MO set where the wake-up signal is located; the starting position 2 is the end time when the terminal listens to the N repeated transmissions of the overlaid OFDM sequence of the wake-up signal, or a specific position in the transmission of the wake-up signal corresponding to the wake-up signal listened to by the terminal.

[0168] Further, as shown in Figure 9, the first type of terminal listens for a first specific type of PDCCH during the PDCCH listening after the first time interval determined at start position 1, such as listening for a terminal-specific PDCCH or listening for PDCCH in a specific search space; while during the PDCCH listening after the first time interval determined at start position 2, it listens for a second specific type of PDCCH or listens for PDCCH without specifying the PDCCH listening type. For example, the second specific type of PDCCH includes group common PDCCH, or includes both group common PDCCH and the first specific type of PDCCH.

[0169] In this way, the terminal only listens to the first specific type of PDCCH in the PDCCH listening time determined by the first time interval starting from the starting position 1, which can reduce the number of blind detections of some PDCCHs.

[0170] In some embodiments, the terminal is a second type of terminal (a second type of terminal is a terminal capable of detecting low-power signals based on OOK waveforms). The start position of the first time interval associated with the second type of terminal is the end time of the MO in which the wake-up signal is detected by the terminal; or, the end time of the WUS listening window or WUS MO set in which the wake-up signal is detected by the terminal.

[0171] It is understandable that starting position 2 is also the starting position of the first time interval associated with the second type of terminal. That is to say, both the first type of terminal and the second type of terminal will start PDCCH listening after the first time interval starting from starting position 2.

[0172] This application provides a communication method, as shown in FIG6, including:

[0173] Step 301: The terminal obtains the list of the first parameter, the second parameter, and the first offset configured on the network side;

[0174] Step 302: If the first parameter is less than the second parameter, the terminal applies the target first offset from the first offset list;

[0175] Wherein, the first parameter is the number of paging opportunities (POs) associated with or indicated by a low-power wake-up signal (LO), the second parameter is the number of POs associated with a paging frame (PF), and the first offset is the frame offset between the LO and the target PO or the target PF.

[0176] In this embodiment, the terminal can determine the first offset of the target it is associated with, thereby determining the start time of the wireless frame where the LO determined by the first offset of the target is located. This avoids the problem of inconsistent understanding between the terminal and the network-side device regarding the LO associated with the terminal, thereby improving the transmission reliability of the low-power wake-up signal.

[0177] It should be noted that a single LO can include one or more LP-WUS MOs.

[0178] In some embodiments, the target PO is the PO associated with or indicated by the LO; the target PF is the PF where the PO associated with or indicated by the LO is located.

[0179] Furthermore, the target PF is the first PF among the PFs containing the PO associated with or indicated by the LO. An LO can be associated with one or more consecutive POs.

[0180] Optionally, an LO can be associated with some or all of the POs in a PF.

[0181] Optionally, an LO can be associated with all POs in up to two consecutive PFs.

[0182] In some embodiments, the target first offset is determined based on at least one of the following: the PO index i associated with the terminal. s The first parameter is POtoLO association, and the second parameter is Ns.

[0183] In some embodiments, the target first offset is the (floor(i)th offset in the first offset list. s / POtoLO association)+1) offsets, or, the index of the target first offset in the first offset list is: (floor(i s / POtoLO association), the index starts from 0.

[0184] In some embodiments, the number of first offsets included in the first offset list is determined based on at least one of the following: the first parameter POtoLO association, and the second parameter Ns.

[0185] In some embodiments, the number of first offsets included in the first offset list is N. s / POtoLO association.

[0186] In some embodiments, the target first offset is N contained in the first offset list. s / POtoLO association, the first offset of the (floor(i)th) s / POtoLO association)+1) offsets.

[0187] In some embodiments, the communication method further includes:

[0188] The terminal determines the starting position of the radio frame containing the LO associated with the terminal based on the first offset of the target.

[0189] In some embodiments, the terminal determines the starting position of the first LP-WUS listening opportunity (LP-WUS MO) of the associated LO based on a second offset;

[0190] Wherein, the second offset is the time interval between the start position of the radio frame where the LO associated with the terminal is located and the start position of the first LP-WUS MO of the LO associated with the terminal.

[0191] Optionally, the second offset is a symbol- or time-slot-level offset.

[0192] Optionally, when the second offset is a slot-level offset, the value range of the second offset is {0, 10*2^μ}. Here, μ is related to the value of the subcarrier spacing (SCS).

[0193] In some embodiments, the value of the first offset is greater than or equal to 8 radio frames.

[0194] In some embodiments, the first offset ranges from {8, ..., 154}.

[0195] In some embodiments, the target PF is the PF where the PO associated with or indicated by the LO is located, and the first offset list contains the target first offset.

[0196] In other embodiments, the first offset may also be the offset between the start position of the radio frame containing the LO and the start position of the first LP-WUS MO of the LO. Furthermore, this first offset can be applied to any one or more of the embodiments described above.

[0197] For example, the communication method in this embodiment includes the following steps:

[0198] The terminal obtains the first parameter, second parameter, and first offset list configured on the network side;

[0199] If the first parameter is less than the second parameter, the terminal applies the target first offset from the first offset list;

[0200] Wherein, the first parameter is the number of paging opportunities (POs) associated with or indicated by a low-power wake-up signal (LO), the second parameter is the number of POs associated with a paging frame (PF), and the first offset is the offset between the start position of the radio frame in which the LO is located and the start position of the first LP-WUS MO of the LO. Further, when the first parameter is less than the second parameter, N s / POtoLO association: LOs share the same network-side device configuration and the frame-level offset between the LO and the PF associated with the LO.

[0201] This application provides a communication method, as shown in FIG7, including:

[0202] Step 401: The network-side device configures at least one of the following parameters: a first parameter, a second parameter, and a first offset list;

[0203] Wherein, the first parameter is the number of paging opportunities (POs) associated with or indicated by a low-power wake-up signal (LO), the second parameter is the number of POs associated with a paging frame (PF), and the first offset is the frame offset between the LO and the target PO or the target PF.

[0204] In some embodiments, as shown in Figure 10, the network-side device configures a PF with 4 POs, where PO1 and PO2 are associated with LO1; and PO3 and PO4 are associated with LO2. That is, the first parameter POtoLO association = 2, and the second parameter Ns = 4. Therefore, the number of first offsets included in the first offset list is: N s / POtoLO association = 2. As shown in Figure 10, the first offset is determined relative to the starting position of PF. Furthermore, terminal 1 is associated with PO3, meaning that the index i of PO3 associated with terminal 1 in PF... s=2. According to the first offset list configured on the network side, terminal 1 applies the (floor(i)th offset from the first offset list. s ( / POtoLO association)+1) = 2 first offsets (that is, the target first offset of terminal 1 is the first offset 2 in the figure). That is, terminal 1 determines the LO2 it needs to monitor, and the frame start position of the radio frame containing LO2, based on the second first offset in the first offset list. Further, the network side configures a second offset. The terminal determines the start position of the first LP-WUS MO of LO2 based on the second offset. The start position of this second offset is the frame start position of the radio frame containing LO2.

[0205] Optionally, the network side also needs to configure a second offset. The second offset is the time interval between the start position of the radio frame containing the LO associated with the terminal and the start position of the first LP-WUS MO of that LO, as shown in Figure 10, where the second offset 1 and the second offset 2 correspond to LO1 and LO2, respectively.

[0206] Furthermore, at least one first offset in the first offset list can have the same or different values. If at least one first offset has the same value, the starting position of the different first LP-WUS MO for different LOs needs to be determined by corresponding second offsets with different values.

[0207] It should be noted that in the above embodiments, the network side configures one first offset for a PO group, meaning one PO is associated with one LO. In other embodiments, the network side can configure two first offsets for a PO group, meaning one PO is associated with two LOs. In these embodiments, the network side needs to configure two sets of first offset lists. However, the terminal only listens to one of the two LOs, meaning that for the terminal, it will only apply one first offset from one first offset list, which is the target first offset.

[0208] The communication method provided in this application can be executed by a communication device. This application uses the example of a communication device executing the communication method to illustrate the communication device provided in this application.
