[0050] For example, a communication system 100 used in an embodiment of the present application is shown in FIG1 . The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal or terminal).

[0052] Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0053] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function.

The communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0054] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0055] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0056] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0057] In the embodiments of the present application, "pre-defined" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device or a network device). The present application does not limit the specific implementation method. For example, pre-defined may refer to information defined in a protocol.

[0058] In the embodiments of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0059] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0060] FIG2 is a schematic diagram of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG2 , the method 200 includes at least part of the following:

[0061] S210 , the network device sends a wake-up signal (WUS), where the wake-up signal includes a target sequence and is used to wake up one or more terminal devices.

[0062] Correspondingly, the terminal device receives WUS.

[0063] In some embodiments, the wake-up signal may be received by the terminal device through a wake-up receiver (WUP) (or low-power receiver).

[0064] It should be understood that the present application does not limit the specific implementation method of the wake-up receiver. For example, as shown in Figure 3, the wake-up receiver can be combined with the terminal device and can serve as an additional module of the receiver of the terminal device, or, as shown in Figure 4, the wake-up receiver can also serve as a wake-up function module of the terminal device alone.

[0065] Specifically, as shown in Figure 3, the terminal device includes a first receiver (or low-power receiver, wake-up receiver) and a second receiver (or main receiver), wherein the power consumption of the first receiver is lower than the power consumption of the second receiver, wherein the wake-up signal is received based on the wake-up receiver, and the wake-up signal is used to wake up the main receiver.

[0066] Specifically, as shown in Figure 4, the terminal device includes a second receiver (or main receiver), and the terminal device has an external wake-up receiver. The power consumption of the wake-up receiver is lower than that of the main receiver, wherein the wake-up signal is received based on the wake-up receiver, and the wake-up signal is used to wake up the main receiver.

[0067] In some embodiments, the primary receiver may have strong information processing capabilities, such as supporting large bandwidth (e.g., 100 MHz), high-speed (e.g., 1 Gbps) information reception and processing, and high-complexity waveform detection. For example, the primary receiver may be an LTE terminal receiver, an NR terminal receiver, or other terminal receivers in future standard evolution.

[0068] In some embodiments, the wake-up receiver may have relatively low information processing capabilities, such as only supporting narrowband, low-rate information reception and processing, and low-complexity waveform detection.

[0069] In some embodiments, the wake-up signal being used to wake up the terminal device may refer to: the wake-up signal being used to wake up a main receiver of the terminal device.

[0070] That is to say, the main receiver can be activated based on the wake-up signal, which is beneficial to reducing the power consumption of the terminal device.

[0071] In some embodiments, the terminal device wakes up the main receiver to monitor the PDCCH or paging message.

[0072] In some embodiments, the target sequence may be used to identify a wake-up signal, and / or for synchronization, and / or for carrying wake-up information.

[0073] For example, the target sequence may include a preamble sequence for identifying a wake-up signal or a synchronization sequence for synchronization, and / or a sequence for carrying wake-up information, which is referred to as a wake-up information sequence.

[0074] It should be understood that in the embodiment of the present application, the preamble sequence can also be used for synchronization, and the synchronization sequence can also be used as the preamble sequence.

[0075] In some embodiments of the present application, the wake-up signal can be generated by a low-complexity modulation method, for example, On-Off Keying (OOK), specifically, multi-carrier OOK modulation. Another example is amplitude shift keying (ASK) modulation, specifically, multi-carrier ASK modulation. The modulation principle of OOK is to modulate the amplitude of the carrier signal to non-zero values ​​and zero values, corresponding to On and Off, respectively, to represent information bits. OOK modulation is also known as binary amplitude keying (2Amplitude Shift Keying, 2ASK). As shown in Figure 5, bit 1 is modulated to On and 0 is modulated to Off, where On can be generated by an On waveform generator (On Waveform Generator, On-WG) and Off can be generated by an Off waveform generator (Off Waveform Generator, Off-WG).

[0076] In some embodiments, the downlink signal is generated using a more complex modulation method, such as Orthogonal Frequency Division Multiplexing (OFDM) modulation. As an implementation, the network device can use OOK modulation or ASK modulation on multiple subcarriers of the OFDM signal to obtain a wake-up signal.

[0077] That is to say, the wake-up signal in the embodiment of the present application can adopt a simple modulation waveform, which is beneficial to reducing the complexity of the wake-up receiver in detecting the wake-up signal.

[0078] In some embodiments, the wake-up signal includes wake-up information, and the wake-up information can be carried through a sequence, or can also be carried in other ways. For example, the wake-up signal directly includes the wake-up information itself, or can also include information bits obtained by encoding the wake-up information. The present application is not limited to this.

[0079] The following describes the carrying method of the wake-up information in conjunction with specific embodiments.

[0080] Embodiment 1: The wake-up information is carried through a sequence.

[0081] Embodiment 1-1: The target sequence includes a first sequence and a second sequence, the first sequence is a preamble sequence or a synchronization sequence, and the second sequence is used to carry wake-up information, that is, the second sequence is a wake-up information sequence.

[0082] FIG6 is a schematic diagram of the composition of a wake-up signal provided by an embodiment of the present application, taking the first sequence as a synchronization sequence as an example.

[0083] Embodiment 1-2: The target sequence includes a second sequence, and the second sequence is used to carry wake-up information.

[0084] For example, as shown in FIG7 , the wake-up signal may include only a wake-up information sequence but not a preamble sequence or a synchronization sequence.

[0085] That is, the wake-up information sequence may be used alone as a wake-up signal, or may be used together with a preamble sequence or a synchronization sequence as a wake-up signal.

[0086] In some embodiments, when the terminal device receives a wake-up signal including a wake-up information sequence, it may be determined that the wake-up information is received. Further, the terminal device may wake up the main receiver.

[0087] It should be understood that this application does not limit the number of bits of the wake-up information. For example, the wake-up information carried in the wake-up signal can be at least 1 bit. Carrying this 1-bit information by the second sequence allows the terminal device to perform correlation detection on the second sequence and receive the wake-up information more reliably.

[0088] In some embodiments, the wake-up information carried in the second sequence can be used to wake up one terminal device, or can also be used to wake up multiple terminal devices, such as all terminal devices in a terminal group.

[0089] In some embodiments, the second sequence (ie, the wake-up information sequence) is obtained by scrambling the third sequence (or characteristic sequence) using identification (ID) information of the terminal device or ID information of the terminal group.

[0090] That is to say, the characteristic sequence can be scrambled using the ID information of the terminal device (for example, UE ID) or the ID information of the terminal group to obtain the actual sent sequence, that is, the second sequence, which is carried in the wake-up signal and sent. In this way, the terminal device can determine whether the wake-up signal is sent to itself based on the ID information of the scrambled characteristic sequence.

[0091] In some embodiments, the identification ID information of the terminal device may be the Radio Network Temporary Identity (RNTI) information of the terminal device. For example, for a terminal device in a connected state, the RNTI may be the Cell Radio Network Temporary Identity (C-RNTI), etc.

[0092] In some embodiments, the signature sequence includes M bits, the UE ID includes N bits, and M > N. Any N bits of the M bits are scrambled with the UE ID to obtain an actually transmitted sequence of M bits.

[0093] In some embodiments, the wake-up information sequence may be generated in the following manner:

[0094] Assume that the wake-up information sequence carried by WUS is C k , k = 0, 1, 2, ..., A-1, where A is the total length of the sequence;

[0095] The characteristic sequence is D k ,k=0,1,2,…,A-1;

[0096] UE ID is R k , k=0,1,2,…,15;

[0097] C k =D k , when k=0,1,2,…,A-17;

[0098] C k =(D k +R k )mod 2, when k=A-16,A-15,…,A-1.

[0099] FIG8 is a schematic diagram showing how to generate a wake-up information sequence (denoted as sequence 2) by taking sequence 1 as a characteristic sequence as an example.

[0100] That is, the last 16 bits of the 32-bit sequence 1 are scrambled using the 16-bit RNTI to obtain a new 32-bit sequence 2, which is used as the sequence actually sent, ie, sequence 2.

[0101] In some embodiments, the third sequence is predefined, or configured by the network device, or determined according to a preset rule. In other words, the terminal device and the network device have the same understanding of the third sequence.

[0102] Optionally, when the terminal device is in a connected state, the third sequence may be configured by the network device, for example, via Radio Resource Control (RRC) signaling or system information. Optionally, when the terminal device is in a space state or an inactive state, the third sequence may be determined according to a preset rule.

[0103] In some embodiments, the third sequence is determined by the terminal device from a first set of candidate sequences.

[0104] In some embodiments, the first set of candidate sequences includes at least one candidate third sequence.

[0105] Optionally, each candidate third sequence in the first candidate sequence set corresponds to a number or index. For example, the first candidate sequence set includes 8 candidate third sequences, and the corresponding numbers or indexes may be 0-7 or 1-8.

[0106] In some embodiments, the third sequence is determined from the first candidate sequence set based on the ID information of the terminal device.

[0107] For example, the signature sequence corresponding to the UE can be calculated based on the UE ID. As an example, the UE ID can be used to perform a modulo calculation on the number of sequences in the first candidate sequence set. The result is used to determine the target third sequence. For example, the result can be the number or index of the target third sequence in the first candidate sequence set. This approach facilitates a relatively even distribution of signature sequences corresponding to different terminal devices across the signature sequences in the first candidate sequence set.

[0108] In some embodiments, the first candidate sequence set is configured by a network device or predefined, for example, through RRC signaling or system information.

[0109] In some embodiments, different terminal devices correspond to different third sequences.

[0110] In some embodiments, different terminal groups correspond to different third sequences.

[0111] That is, the third sequence is configured for each terminal device, or the third sequence is configured for each terminal group.

[0112] In other words, different terminal devices or terminal groups can be distinguished according to the third sequence.

[0113] For example, the network device may configure different third sequences for different terminal devices.

[0114] For another example, the network device can configure different third sequences for different terminal groups. Each terminal group uses the same third sequence, and different second sequences are formed by scrambling different UE IDs on the third sequence, corresponding to the wake-up information of different terminal devices.

[0115] In other embodiments, the third sequence corresponding to different terminal devices may be the same. In this case, the third sequence may be scrambled using the ID information of different terminal devices to obtain different second sequences to distinguish different terminal devices. Alternatively, different terminal devices may be distinguished using different preamble sequences or synchronization sequences.

[0116] In other embodiments, the third sequences corresponding to different terminal groups may be the same. In this case, the third sequences may be scrambled using the ID information of the different terminal groups to obtain different second sequences to distinguish the different terminal groups. Alternatively, different terminal groups may be distinguished using different preamble sequences or synchronization sequences.

[0117] In some embodiments, the third sequences used by different terminal devices or terminal groups are generated based on different sequences, or the third sequences used by different terminals or terminal groups are generated based on different cyclic shifts (CS) of the same sequence.

[0118] In some embodiments, the first sequence is predefined, or configured by the network device, or determined according to a preset rule. That is, the terminal device and the network device have the same understanding of the first sequence.

[0119] Optionally, when the terminal device is in a connected state, the first sequence may be configured by the network device, for example, via RRC signaling or system information. Optionally, when the terminal device is in a space state or an inactive state, the first sequence may be determined according to a preset rule.

[0120] For example, the first sequence may adopt a predefined sequence W containing 32 bits.

[0121] W=[1 0 1 0 0 1 0 0 1 0 1 1 1 0 1 1 0 0 0 1 0 1 1 1 0 0 1 1 1 0 0 0].

[0122] In some embodiments, different first sequences may be used for different terminal devices or terminal groups.

[0123] For example, the first sequences used by different terminal devices or terminal groups are generated based on different sequences, or the first sequences used by different terminals or terminal groups are generated based on different cyclic shifts of the same sequence.

[0124] In other embodiments, the same first sequence may be used for different terminal devices or terminal groups. Furthermore, different terminal devices or terminal groups may be distinguished by a second sequence.

[0125] In some embodiments, the first sequence is determined by the terminal device from a second set of candidate sequences.

[0126] In some embodiments, the second set of candidate sequences includes at least one candidate first sequence.

[0127] Optionally, each candidate first sequence in the second candidate sequence set corresponds to a number or index. For example, the second candidate sequence set includes 8 candidate first sequences, and the corresponding numbers or indexes may be 0-7 or 1-8.

[0128] In some embodiments, the first sequence is determined from a second candidate sequence set based on ID information of the terminal device.

[0129] For example, the first sequence corresponding to the UE is calculated based on the UE ID. As an example, the number of sequences in the second candidate sequence set is modulo the UE ID, and the result is used to determine the target first sequence. For example, the result can be the number or index of the target first sequence in the second candidate sequence set. This approach facilitates a relatively even distribution of the first sequences corresponding to different terminal devices to the various first sequences in the second candidate sequence set.

[0130] In some embodiments, the second candidate sequence set is configured by a network device or predefined, for example, through RRC signaling or system information.

[0131] In summary, for Example 1-1, different terminal devices or terminal groups can be distinguished based on the first sequence and / or the second sequence.

[0132] For example, different terminal devices or terminal groups correspond to different preamble sequences or synchronization sequences.

[0133] For another example, different terminal devices or terminal groups correspond to different wake-up information sequences.

[0134] For embodiments 1-2, different terminal devices or terminal groups can be distinguished based on the second sequence.

[0135] In some embodiments, different wake-up information sequences corresponding to different terminal devices or terminal groups can be implemented in the following manner (applicable to Embodiment 1-1 and Embodiment 1-2):

[0136] Different terminal devices or terminal groups correspond to different feature sequences; and / or

[0137] The wake-up information sequences corresponding to different terminal devices or terminal groups are encrypted based on different UE-IDs or terminal group IDs. In this case, the characteristic sequences corresponding to different terminal devices or terminal groups may be the same or different.

[0138] Embodiment 2: The wake-up signal includes wake-up information. In other words, the wake-up signal includes explicit wake-up information.

[0139] In some embodiments, the wake-up signal may include the wake-up information itself, or may include information bits obtained by encoding the wake-up information. Carrying the wake-up information in this manner is beneficial for improving transmission reliability. Optionally, the encoding method may include, but is not limited to, non-return-to-zero (NRZ) encoding, Manchester encoding, unipolar return-to-zero encoding, differential bi-phase (DBP) encoding, differential encoding, pulse interval encoding (PIE), bidirectional space encoding (FMO), Miller encoding, differential encoding, etc.

[0140] For example, in Manchester coding, if the wake-up information is 0, it is coded as 10, or if the wake-up information is 1, it is coded as 01. The wake-up signal carries the coded wake-up information.

[0141] In the following, the wake-up information in the wake-up signal is described as the wake-up information before encoding, but the present application is not limited thereto.

[0142] In some embodiments, the target sequence includes a first sequence, which is a leading sequence or a synchronization sequence, and the wake-up signal also includes target wake-up information, which includes wake-up information of at least one terminal device, or wake-up information of at least one terminal group, or wake-up information of at least one terminal subgroup in a terminal group.

[0143] In some embodiments, a terminal group may include multiple terminal sub-groups, wherein a terminal sub-group may include one or more terminal devices.

[0144] That is, the wake-up signal may indicate wake-up information at the granularity of a terminal device, wake-up information at the granularity of a terminal group, or wake-up information at the granularity of a terminal sub-group.

[0145] FIG9 is a schematic diagram of the composition of another wake-up signal provided by an embodiment of the present application, taking the first sequence as the synchronization sequence as an example.

[0146] As shown in FIG9 , the wake-up signal may include a synchronization sequence and target wake-up information.

[0147] In some embodiments, whether to wake up the at least one terminal device or the at least one terminal group or the at least one terminal sub-group may be indicated by a bitmap.

[0148] For example, the target wake-up information includes multiple bit groups, each bit group corresponds to a terminal device, a terminal group, or a terminal subgroup, and the value of each bit group is used to indicate whether to wake up the corresponding terminal device, terminal group, or terminal subgroup, wherein each bit group includes one or more bits. For example, a bit group includes one bit, and a value of 1 indicates wake-up, and a value of 0 indicates not wake-up.

[0149] As shown in FIG9 , the target wake-up information may include 12 bits, and the 12 bits may correspond to 12 UEs, each bit corresponds to one UE, and the value of each bit is used to indicate whether to wake up the corresponding UE.

[0150] In some embodiments, the wake-up signal further includes check bit information for checking target wake-up information.

[0151] For example, the wake-up signal may also include cyclic redundancy check (CRC) information, which is obtained by performing a CRC calculation on the target wake-up information. By including the CRC information and the target wake-up information in the wake-up signal and transmitting them together, a terminal device that receives the wake-up signal can perform a CRC check on the target wake-up information based on the CRC information to determine whether the received target wake-up information is correct.

[0152] Figure 10 is a schematic diagram of another information composition of a wake-up signal provided by an embodiment of the present application, taking the first sequence as an example of a synchronization sequence. As shown in Figure 10, the wake-up signal may include a synchronization sequence, target wake-up information, and CRC information.

[0153] In some embodiments, the bit position of the wake-up information of each terminal device in the target wake-up information is configured by the network device, or determined according to a preset rule. That is, the terminal device and the network device have a consistent understanding of the bit position of the wake-up information of the terminal device in the target wake-up information.

[0154] For example, the correspondence between the wake-up information of each terminal device and the one or more bits may be configured by a network device, or determined according to a preset rule.

[0155] Optionally, the correspondence between the wake-up information of each terminal device and the one or more bits can be configured through RRC signaling or system information.

[0156] For another example, the bit position occupied by the wake-up information of the at least one terminal device in the target wake-up signal is determined according to the ID information of the at least one terminal device.

[0157] As an example, the number of bits (or number of bit groups) contained in the target wake-up information carried in the wake-up signal is modulo calculated by the UE ID, and the result is used to determine the bit position of the wake-up information corresponding to the UE in the target wake-up information carried in the wake-up signal. For example, the result can be used to represent the bit number or index occupied by the wake-up information corresponding to the UE in the target wake-up information. In this way, the wake-up information corresponding to different terminal devices is more evenly distributed to each bit in the wake-up information carried in the wake-up signal.

[0158] In some embodiments, the bit position of the wake-up information of each terminal group in the at least one terminal group in the target wake-up information is configured by the network device, or determined according to a preset rule. That is, the terminal device and the network device have a consistent understanding of the bit position of the wake-up information of the terminal group in the target wake-up information.

[0159] For example, the wake-up information of each terminal group corresponds to one or more bits in the target wake-up information, and the correspondence between the wake-up information of each terminal group and the one or more bits may be configured by a network device, or determined according to a preset rule.

[0160] Optionally, the correspondence between the wake-up information of each terminal group and the one or more bits may be configured through RRC signaling or system information.

[0161] For another example, the bit position occupied by the wake-up information of the at least one terminal group in the target wake-up signal is determined according to the ID information of the at least one terminal group.

[0162] As an example, the number of bits (or number of bit groups) contained in the target wake-up information carried in the wake-up signal is modulo calculated by the ID of the terminal group, and the result is used to determine the bit position of the wake-up information corresponding to the terminal group in the target wake-up information carried in the wake-up signal. For example, the result can be used to represent the bit number or index occupied by the wake-up information corresponding to the terminal group in the target wake-up information. In this way, the wake-up information corresponding to different terminal groups is more evenly distributed to each bit in the wake-up information carried in the wake-up signal.

[0163] In some embodiments, the bit position of the wake-up information of each terminal subgroup in the target wake-up information is configured by the network device, or determined according to a preset rule. That is, the terminal device and the network device have a consistent understanding of the bit position of the wake-up information of the terminal subgroup in the target wake-up information.

[0164] For example, the wake-up information corresponding to each terminal subgroup corresponds to one or more bits in the target wake-up information. The correspondence between the wake-up information of each terminal subgroup and the one or more bits may be configured by a network device or determined according to a preset rule.

[0165] Optionally, the correspondence between the wake-up information of each terminal subgroup and the one or more bits may be configured through RRC signaling or system information.

[0166] For another example, the bit position occupied by the wake-up information corresponding to each terminal subgroup in the target wake-up information may be determined according to the number or index of the terminal subgroup in the terminal group.

[0167] For example, a terminal group includes 12 terminal subgroups numbered 0 to 11. When the target wakeup information includes 12 bits (B0 to B11), B0 to B11 correspond to the terminal subgroups numbered 0 to 11, respectively.

[0168] Optionally, in this embodiment 2, the first sequence is predefined, or configured by a network device, or determined according to a preset rule, for example, configured through RRC signaling or system information.

[0169] For example, the first sequence may adopt a predefined sequence W containing 32 bits.

[0170] W=[1 0 1 0 0 1 0 0 1 0 1 1 1 0 1 1 0 0 0 1 0 1 1 1 0 0 1 1 1 0 0 0].

[0171] Embodiment 3: The wake-up signal includes implicit wake-up information.

[0172] In this embodiment 3, the terminal device, terminal group or terminal sub-group to be awakened can be implicitly indicated.

[0173] In some embodiments, the wake-up signal includes a first sequence, and ID information of a target terminal, or ID information of a target terminal group, or ID information of a target terminal subgroup.

[0174] Optionally, the target terminal ID information may be used to indicate the target terminal to be awakened, the target terminal group ID information may be used to indicate the target terminal group to be awakened, and the target terminal subgroup ID information may be used to indicate the target terminal subgroup to be awakened.

[0175] In some embodiments, the wake-up signal further includes check bit information for checking the ID information of the target terminal to be awakened, the ID information of the target terminal group, or the ID information of the target terminal subgroup.

[0176] For example, the wake-up signal may also include CRC information, which is obtained by performing a CRC calculation on the ID information of the target terminal, the ID information of the target terminal group, or the ID information of the target terminal subgroup. By including the CRC and the ID information of the target terminal, the ID information of the target terminal group, or the ID information of the target terminal subgroup in the wake-up signal and transmitting them together, a terminal device that receives the wake-up signal can perform a CRC check on the ID information of the target terminal, the ID information of the target terminal group, or the ID information of the target terminal subgroup based on the CRC information to determine whether the received ID information of the target terminal, the ID information of the target terminal group, or the ID information of the target terminal subgroup is correct.

[0177] FIG11 is a schematic diagram of another information composition of a wake-up signal provided in an embodiment of the present application, taking the first sequence as the synchronization sequence as an example.

[0178] As shown in FIG11 , the wake-up signal may include a synchronization sequence, a UE identifier or a UE group identifier, and CRC information.

[0179] Optionally, in this embodiment 3, the first sequence is predefined, or configured by a network device, or determined according to a preset rule, for example, configured through RRC signaling or system information.

[0180] For example, the first sequence may adopt a predefined sequence W containing 32 bits.

[0181] W=[1 0 1 0 0 1 0 0 1 0 1 1 1 0 1 1 0 0 0 1 0 1 1 1 0 0 1 1 1 0 0 0].

[0182] Embodiment 4: Different terminal devices or terminal groups are distinguished by transmission resources.

[0183] In some embodiments, the transmission resources of the wake-up signals corresponding to different terminal devices are different.

[0184] That is to say, the wake-up signals for different terminal devices can be transmitted using different transmission resources.

[0185] In some embodiments, the transmission resources of the wake-up signals corresponding to different terminal groups are different.

[0186] That is, the wake-up signals for different terminal groups may be transmitted using different transmission resources.

[0187] Correspondingly, for different terminal devices or terminal devices belonging to different terminal groups, the wake-up signal can be detected on the corresponding transmission resources.

[0188] In some embodiments, the transmission resource may refer to any transmission resource of a signal, for example, may include time domain resources and / or frequency domain resources, or may also include other transmission resources, such as code domain resources.

[0189] For example, the frequency domain resources of the wake-up signals corresponding to different terminal devices or terminal groups are different.

[0190] For another example, the time-frequency resources of the wake-up signals corresponding to different terminal devices or terminal groups are different.

[0191] In some embodiments, the transmission resources for the wake-up signals corresponding to different terminal devices are configured by the network device or determined according to a preset rule. For example, this can be configured through RRC signaling or system information. In other words, the terminal device and the network device have a consistent understanding of the location of the transmission resources corresponding to the wake-up signal.

[0192] In some embodiments, the transmission resources for the wake-up signals corresponding to different terminal groups are configured by the network device or determined according to a preset rule. For example, this can be configured through RRC signaling or system information. In other words, the terminal device and the network device have a consistent understanding of the location of the transmission resources corresponding to the wake-up signals.

[0193] Taking frequency domain resources as an example, the wake-up signals for different terminal devices or terminal groups can be configured to correspond to different frequency domain resources. Accordingly, different terminal devices or terminal groups detect the wake-up signals on different frequency domain resources to obtain wake-up information. As shown in Figure 12, the wake-up signals corresponding to UE1, UE2, and UE3 are configured on different frequency domain resources. Accordingly, UE1, UE2, and UE3 detect the wake-up signals on different frequency domain resources.

[0194] Taking time-frequency resources as an example, the wake-up signals for different terminal devices or terminal groups can be configured to correspond to different time-frequency resources. Accordingly, different terminal devices or terminal groups detect the wake-up signals on different time-frequency resources to obtain wake-up information. As shown in Figure 13, the wake-up signals for UE1, UE2, and UE3 are configured on different time-frequency resources. Accordingly, UE1, UE2, and UE3 detect the wake-up signals on different time-frequency resources.

[0195] It should be understood that in an embodiment of the present application, the wake-up information of different terminal devices or terminal groups can be distinguished only by transmission resources, or the wake-up information of different terminal devices or terminal groups can be distinguished only by sequences (such as leading sequences or synchronization sequences, or characteristic sequences, etc.), or the wake-up information of different terminal devices or terminal groups can be distinguished by transmission resources and sequences.

[0196] For example, the wake-up signals corresponding to different terminal devices or terminal groups are distinguished by two dimensions: frequency domain resources and characteristic sequences. For example, on the same frequency domain resources, the wake-up signals sent using different third sequences or first sequences correspond to different terminal devices or terminal groups. Optionally, the third sequence may be the third sequence in Example 1, and the first sequence may be the first sequence in Example 2.

[0197] For another example, the wake-up signals corresponding to different terminal devices or terminal groups are distinguished by three dimensions: time domain resources, frequency domain resources, and characteristic sequences. For example, on the same time-frequency resources, the wake-up signals sent using different third sequences or first sequences correspond to different terminal devices or terminal groups. Optionally, the third sequence may be the third sequence in Example 1, and the first sequence may be the first sequence in Example 2.

[0198] In some embodiments, if the wake-up signal transmission resource is targeted at a terminal device or terminal group, the wake-up signal may not include the terminal device ID information or the terminal group ID information. Upon receiving the wake-up signal on the corresponding transmission resource, the terminal device may determine that the wake-up signal contains its own wake-up information. Furthermore, the terminal device may wake up the primary receiver based on this wake-up information.

[0199] In summary, Embodiments 1 to 4 may distinguish different terminal devices or terminal groups by the transmission resources of the wake-up signal, and / or may distinguish different terminal devices or terminal groups by different third sequences or first sequences.

[0200] Optionally, when the terminal device is in a connected state, the transmission resources of the wake-up signals corresponding to different terminal devices may be configured by the network device, for example, via RRC signaling or system information. Optionally, when the terminal device is in a space state or an inactive state, the transmission resources of the wake-up signals corresponding to different terminal devices may be determined according to preset rules.

[0201] Optionally, when the terminal device is in a connected state, the transmission resources of the wake-up signals corresponding to different terminal groups may be configured by the network device, for example, via RRC signaling or system information. Optionally, when the terminal device is in a spaced state or an inactive state, the transmission resources of the wake-up signals corresponding to different terminal groups may be determined according to a preset rule.

[0202] In some embodiments, the transmission resource of the wake-up signal corresponding to the terminal device is determined in a set of candidate wake-up signal transmission resources according to a preset rule.

[0203] In some embodiments, the candidate wake-up signal transmission resource set may include at least one candidate signal transmission resource.

[0204] Optionally, each candidate signal transmission resource in the candidate wake-up signal transmission resource set corresponds to a number or index. For example, the candidate wake-up signal transmission resource set includes 8 candidate signal transmission resources, and the corresponding numbers or indexes may be 0-7 or 1-8.

[0205] In some embodiments, the transmission resources of the wake-up signals corresponding to different terminal devices are determined based on the ID information of the terminal devices.

[0206] For example, the number of transmission resources in the candidate wake-up signal transmission resource set is modulo calculated by the UE ID, and the result is used to determine the location of the target transmission resource. For example, the result can be the number or index of the target transmission resource in the candidate wake-up signal transmission resource set. In this way, the transmission resources of the wake-up signals corresponding to different terminal devices can be more evenly distributed among the transmission resources in the candidate wake-up signal transmission resource set.

[0207] It should be understood that a similar method to the above may be used to determine the transmission resource of the wake-up signal corresponding to the terminal group. For the sake of brevity, details will not be given here.

[0208] In some embodiments, the candidate wake-up signal transmission resource set is configured by a network device or predefined, for example, through RRC signaling or system information.

[0209] Optionally, in some embodiments, the transmission resource used to transmit the wake-up signal may be a dedicated transmission resource. That is, the terminal device can determine that the signal it receives is a wake-up signal based on the transmission resource. In this case, the wake-up signal may also optionally not include a preamble sequence used to identify the wake-up signal.

[0210] It should be understood that Example 4 can be implemented alone, or can be implemented in combination with any one of Examples 1 to 3, and this application does not limit this.

[0211] In some embodiments, Example 4 can be implemented in combination with Example 2. For example, in Example 4, the transmission resources of the wake-up signals corresponding to different terminal groups are different, that is, the terminal group corresponding to the wake-up signal can be determined by the transmission resources. Furthermore, in Example 2, different bits in the target wake-up information in the wake-up signal can correspond to different terminal devices or terminal subgroups, and the wake-up information corresponding to different terminal devices or different terminal subgroups in the terminal group can be determined based on the target wake-up information.

[0212] In some embodiments, Example 4 can also be implemented in combination with Example 3. For example, in Example 4, the transmission resources of the wake-up signals corresponding to different terminal groups are different, that is, the terminal group corresponding to the wake-up signal can be determined by the transmission resources. Furthermore, in Example 3, the wake-up signal can include identification information of the terminal device or terminal subgroup in the terminal group, indicating the terminal device or terminal subgroup to be awakened in the terminal group.

[0213] In summary, in an embodiment of the present application, a network device can send a wake-up signal to a terminal device, wherein the wake-up signal includes a target sequence, and the target sequence is used to identify the wake-up signal and / or for synchronization and / or for carrying wake-up information. Furthermore, the terminal device can wake up a main receiver with higher power consumption based on the wake-up signal to receive signals, which is beneficial to reducing the power consumption of the terminal device.

[0214] In some implementations, the wake-up information may be carried by a sequence. In this case, the wake-up signal may include a preamble sequence or a synchronization sequence, or may not include a preamble sequence or a synchronization sequence.

[0215] In some implementations, the wake-up signal includes a preamble sequence or synchronization sequence and target wake-up information. The target wake-up information may include wake-up information for multiple terminal devices or multiple terminal groups. The bit positions of the wake-up information for different terminal devices or terminal groups in the target wake-up information may be configured by the network device or determined according to a preset rule.

[0216] In some implementations, the wake-up signal may include a preamble sequence or a synchronization sequence and identification information of a terminal device or terminal group to be awakened.

[0217] In some implementations, the wake-up signals of different terminal devices or terminal groups may correspond to different transmission resources, for example, to different frequency domain resources, or to different time-frequency resources.

[0218] In some embodiments, different terminal devices or terminal groups can be distinguished by different leading sequences or synchronization sequences, or different terminal devices or terminal groups can be distinguished by different characteristic sequences, or different terminal devices or terminal groups can be distinguished by scrambling the characteristic sequence using the ID information of the terminal device or the ID information of the terminal group.
