Communication method and system, and related device

Abstract

Embodiments of the present application provide a communication method and system, and a related device. The method comprises: receiving a first segment of a wake-up signal in a first MO (monitoring occasion) of the wake-up signal; determining, on the basis of the first segment or information related to the first segment, whether a segment corresponding to UE is present in a second MO of the wake-up signal, the second MO being located after the first MO in time domain. Thus, during the process in which a network device sends one or more segments of a wake-up signal to UE, the UE can determine, on the basis of a first segment or information related to the first segment, whether a segment corresponding to the UE is present in a second MO of the wake-up signal. In addition, when no segment of the wake-up signal corresponding to the UE is present, the UE can, in the second MO, skip performing the process of monitoring for the segments of the wake-up signal. Thus, the number of MOs used for the UE to monitor the signal can be reduced, so that energy consumption of the UE can be reduced in the second MO (and in the subsequent MOs), thereby achieving energy saving.

Description

Communication method, system and related device

[0001] The present application claims priority to a Chinese patent application No. 202411392424.7, filed on September 30, 2024, entitled "Communication method, system and related device", and to a Chinese patent application No. 202411845031.7, filed on December 12, 2024, entitled "Communication method, system and related device", the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a communication method, system and related device. BACKGROUND

[0003] With the continuous development of mobile communication technology, the power consumption management of user equipment (UE) has gradually become an important issue of increasing concern. Under normal circumstances, the UE can enter a sleep state, at which time the UE can not need to listen to a physical downlink control channel (PDCCH) subframe, thereby reducing the power consumption of the UE. If the UE is awakened, the UE can enter a working state from the sleep state and start listening to the PDCCH subframe to perform corresponding services.

[0004] In actual application scenarios, a base station can wake up a UE by sending a wake-up signal to the UE, which can be a low-power wake-up signal (LP-WUS) or the like. The UE can receive the wake-up signal through its own low-power wake-up receiver (LP-WUR) and determine whether to trigger the main receiver (MR) in the UE to start listening to the PDCCH subframe based on the wake-up signal, so that the UE enters a working state.

[0005] However, this implementation of waking up the UE to start listening to the PDCCH subframe still causes the UE's energy consumption to remain at a high level. SUMMARY

[0006] The present application provides a communication method, system and related device, which aims to segment the load carried by the LP-WUS and instruct the UE whether to receive the next segment when the UE receives the segment, thereby effectively reducing the power consumption of the UE.

[0007] In order to achieve the above purpose, the present application provides the following technical solutions:

[0008] In a first aspect, the present disclosure provides a method for communication, which is applied to a user equipment (UE). The method comprises: receiving a first segment of a wake-up signal (e.g., a LP-WUS) in a first monitoring occasion of the wake-up signal; and determining whether there is a segment corresponding to the UE in a second monitoring occasion of the wake-up signal according to the first segment or information related to the first segment, the second monitoring occasion being located after the first monitoring occasion in time domain.

[0009] Thus, since the UE can determine whether there is a segment corresponding to the UE in a second monitoring occasion of the wake-up signal according to the first segment or information related to the first segment in the process of sending one or more segments of the wake-up signal by the network device to the UE, the UE can not perform the process of monitoring the segments of the wake-up signal in the second monitoring occasion in the case that there is no segment of the wake-up signal corresponding to the UE, so as to reduce the number of monitoring occasions used by the UE when monitoring the signal, thereby reducing the energy consumption of the UE in the second monitoring occasion (and subsequent monitoring occasions) and achieving energy saving.

[0010] In a possible implementation, the method further comprises: if the UE determines that there is no segment corresponding to the UE in the second monitoring occasion of the wake-up signal according to the first segment or information related to the first segment, the UE does not monitor the segments of the wake-up signal in the second monitoring occasion. Thus, the UE can not perform the process of monitoring the segments of the wake-up signal in the second monitoring occasion in the case that there is no segment of the wake-up signal corresponding to the UE, so as to reduce the number of monitoring occasions used by the UE when monitoring the signal, thereby reducing the energy consumption of the UE in the second monitoring occasion (and subsequent monitoring occasions) and achieving energy saving.

[0011] In a possible implementation, the first segment carries an identifier of the first segment. Thus, the UE can obtain the identifier of the first segment according to the first segment, and then the UE can determine whether the identifier of the first segment is consistent with an identifier of a segment corresponding to a set to which the UE belongs. In the case that the identifier of the first segment is consistent with the identifier of the segment corresponding to the set to which the UE belongs, the UE does not need to continue to receive the segments of the wake-up signal in subsequent MOs (including the second MO and other MOs) of the monitoring period, so as to reduce the energy consumption of the UE and achieve energy saving.

[0012] Further, the wake-up signal comprises a plurality of segments, and the sequence arrangement between the identities of the plurality of segments. In this way, the UE can determine whether the identity of the first segment is sequentially after the identity of the segment corresponding to the set to which the UE belongs. In the case that the identity of the first segment is sequentially after the identity of the segment corresponding to the set to which the UE belongs, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the monitoring period, thereby reducing the capability consumption of the UE and achieving energy saving.

[0013] In a possible implementation, the information related to the first segment comprises an end symbol received in the first monitoring occasion, and the end symbol is used to indicate that the first segment is the last segment transmitted by the network device in the monitoring period of the wake-up signal. In this way, the UE can determine whether to continue to receive the segments of the wake-up signal in the second MO according to whether the end symbol is received in the first MO. That is, in the case that the UE receives the end symbol in the first MO, the UE can determine that there is no segment of the wake-up signal corresponding to the UE in the second MO (the network device will not transmit the segment of the wake-up signal in the second MO, and the first segment is the last segment transmitted by the network device in the wake-up period), so that the UE does not monitor the segments of the wake-up signal in the second MO, thereby reducing the capability consumption of the UE and achieving energy saving.

[0014] In a possible implementation, the end symbol is received. Then, when determining whether there is a segment corresponding to the UE in the second monitoring occasion of the wake-up signal according to the information related to the first segment, the determination can be specifically according to the end symbol.

[0015] In a possible implementation, the first segment carries an end symbol, and the end symbol is used to indicate that the first segment is the last segment transmitted by the network device in the monitoring period. In this way, the UE can determine whether to continue to receive the segments of the wake-up signal in the second MO according to whether the end symbol is carried in the first segment. That is, in the case that the end symbol is carried in the first segment, the UE can determine that there is no segment of the wake-up signal corresponding to the UE in the second MO (the network device will not transmit the segment of the wake-up signal in the second MO, and the first segment is the last segment transmitted by the network device in the wake-up period), so that the UE does not monitor the segments of the wake-up signal in the second MO, thereby reducing the capability consumption of the UE and achieving energy saving.

[0016] In a possible implementation, the information related to the first segment includes a target number, the target number being a number of segments sent by the network device in the listening period of the wake-up signal, and the first segment being one of the segments sent by the network device in the listening period of the wake-up signal. In this way, in a case where the number of segments of the wake-up signal received by the UE in the listening period reaches the target number, and the first segment is the last segment sent by the network device in the listening period, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period, so as to reduce the capability consumption of the UE and save energy.

[0017] In a possible implementation, the first segment carries the target number. In this way, the UE can obtain the target number according to the first segment, and in a case where the number of segments of the wake-up signal received by the UE in the listening period reaches the target number, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period, so as to reduce the capability consumption of the UE and save energy.

[0018] In a possible implementation, the information related to the first segment includes a low-power synchronization signal (LPSS). In this way, the UE can obtain the target number by receiving the low-power synchronization signal (LPSS), and in a case where the number of segments of the wake-up signal received by the UE in the listening period reaches the target number, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period, so as to reduce the capability consumption of the UE and save energy.

[0019] In a possible implementation, the identification of the first segment or the information related to the first segment includes at least one of a superposition sequence corresponding to the first segment, a preamble sequence of the first segment, scrambling information corresponding to the first segment, and a target field in the first segment. In this way, the UE can obtain the identification of the first segment or the information related to the first segment by at least one of parsing the superposition sequence corresponding to the first segment, the preamble sequence of the first segment, the scrambling information corresponding to the first segment, and a newly defined field in the first segment, and in a case where the number of segments of the wake-up signal received by the UE in the listening period reaches the target number, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period, so as to reduce the capability consumption of the UE and save energy.

[0020] For example, the information related to the first segment can be an end symbol or a target number, where the end symbol is used to indicate that the first segment is the last segment sent by the network device in the listening period of the wake-up signal, and the target number is a number of segments sent by the network device in the listening period of the wake-up signal.

[0021] In a possible implementation, the segments of the wake-up signal correspond to a plurality of superposition sequences, the identification of the first segment or the information related to the first segment is carried in a first superposition sequence in the plurality of superposition sequences; or, the segments of the wake-up signal correspond to a plurality of preamble sequences, the identification of the first segment or the information related to the first segment is carried in a first preamble sequence in the plurality of preamble sequences; or, the segments of the wake-up signal correspond to a plurality of scrambling information, the identification of the first segment or the information related to the first segment is carried in a first scrambling information in the plurality of scrambling information. In this way, the UE can obtain the identification of the first segment or the information related to the first segment according to a mapping relationship between the identification of the first segment or the information related to the first segment and the first superposition sequence in the plurality of superposition sequences, or according to a mapping relationship between the identification of the first segment or the information related to the first segment and the first preamble sequence in the plurality of preamble sequences, or according to a mapping relationship between the identification of the first segment or the information related to the first segment and the first scrambling information in the plurality of scrambling information. Further, the UE can determine whether to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period according to the identification of the first segment or the information related to the first segment, so as to reduce the capability consumption of the UE and save energy.

[0022] In a possible implementation, the information related to the first segment includes a time domain offset, the time domain offset is used to indicate a time length between a time when the UE receives the first segment and a starting time of the first listening occasion. In this way, different sizes of the time domain offset can be mapped to different information, and the UE can determine whether to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period according to the time domain offset, so as to reduce the capability consumption of the UE and save energy.

[0023] In a possible implementation, the wake-up signal includes target bits, a number of the target bits is used to indicate that the wake-up signal includes a plurality of segments, the first segment is one of the plurality of segments, each bit in the target bits corresponds to a UE in a set, and a value of each bit is used to indicate whether the UE in the set performs a target operation. In this way, the UE determines that the wake-up signal includes a plurality of segments and a segment corresponding to the UE in the plurality of segments according to the number of the target bits, and further, the UE can determine whether there is a segment of the wake-up signal corresponding to the UE in the subsequent listening occasion according to the first segment or the information related to the first segment (whether the UE does not receive the segment corresponding to the UE), and in the case that there is no segment of the wake-up signal corresponding to the UE, the UE can not perform the process of listening to the segments of the wake-up signal in the second listening occasion, so as to reduce the capability consumption of the UE and save energy.

[0024] In a possible implementation, the method further includes: receiving indication information, the indication information being used to indicate that the wake-up signal includes multiple segments and a segment corresponding to the UE in the multiple segments. In this way, the UE determines, through the indication information, that the wake-up signal includes multiple segments and a segment corresponding to the UE in the multiple segments, and then the UE can determine, in combination with the first segment or information related to the first segment, whether there is a segment of the wake-up signal corresponding to the UE in a subsequent monitoring occasion (whether the UE does not receive the segment corresponding to the UE), and in the case where there is no segment of the wake-up signal corresponding to the UE, the UE can not perform the process of monitoring the segment of the wake-up signal in the second monitoring occasion, thereby reducing the capability consumption of the UE and achieving energy saving.

[0025] In a second aspect, the present application provides a communication method, the method being applied to a network device, and the method includes: generating a first segment of a wake-up signal; and transmitting the first segment of the wake-up signal in a first monitoring occasion of the wake-up signal, the first segment or information related to the first segment being used to indicate whether there is a segment corresponding to a UE in a second monitoring occasion of the wake-up signal, the second monitoring occasion being located after the first monitoring occasion in the time domain.

[0026] In this way, the UE receiving the first segment can determine, according to the first segment or information related to the first segment, whether there is a segment of the wake-up signal corresponding to the UE in a subsequent monitoring occasion, and in the case where there is no segment of the wake-up signal corresponding to the UE, the UE can not perform the process of monitoring the segment of the wake-up signal in the second monitoring occasion, thereby reducing the number of monitoring occasions used by the UE when monitoring the signal, and thus reducing the energy consumption of the UE in the second monitoring occasion (and subsequent monitoring occasions) and achieving energy saving.

[0027] In a possible implementation, the first segment carries an identifier of the first segment. In this way, the UE receiving the first segment can obtain the identifier of the first segment according to the first segment, and then the UE can determine whether the identifier of the first segment is consistent with an identifier of a segment corresponding to a set to which the UE belongs. In the case where the identifier of the first segment is consistent with the identifier of the segment corresponding to the set to which the UE belongs, the UE does not need to continue to receive the segment of the wake-up signal in subsequent MOs (including the second MO and other MOs) of the monitoring period, thereby reducing the capability consumption of the UE and achieving energy saving.

[0028] Further, the wake-up signal comprises a plurality of segments, and the sequence arrangement between the identities of the plurality of segments. Thus, the UE receiving the first segment can determine whether the identity of the first segment is behind the identity of the segment corresponding to the set to which the UE belongs in sequence. In the case that the identity of the first segment is behind the identity of the segment corresponding to the set to which the UE belongs in sequence, the UE receiving the first segment does not need to continue receiving the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period, so as to reduce the capability consumption of the UE and save energy.

[0029] In a possible implementation, the information related to the first segment comprises an end symbol sent in the first listening occasion, and the end symbol is used to indicate that the first segment is the last segment sent by the network device in the listening period of the wake-up signal. Thus, the UE receiving the first segment can determine whether to continue receiving the segments of the wake-up signal in the second MO according to whether the end symbol is received in the first MO, that is, in the case that the UE receives the end symbol in the first MO, the UE can determine that there is no segment of the wake-up signal corresponding to the UE in the second MO (the network device will not send the segment of the wake-up signal in the second MO, and the first segment is the last segment sent by the network device in the wake-up period), so that the UE does not listen to the segments of the wake-up signal in the second MO, so as to reduce the capability consumption of the UE and save energy.

[0030] In a possible implementation, the network device can also send the end symbol. Thus, when the UE determines whether there is a segment corresponding to the UE in the second listening occasion of the wake-up signal according to the information related to the first segment, the UE can determine whether there is a segment corresponding to the UE in the second listening occasion of the wake-up signal according to the end symbol.

[0031] In a possible implementation, the first segment carries the end symbol, and the end symbol is used to indicate that the first segment is the last segment sent by the network device in the listening period. Thus, the UE receiving the first segment can determine whether to continue receiving the segments of the wake-up signal in the second MO according to whether the end symbol is carried in the first segment, that is, in the case that the end symbol is carried in the first segment, the UE can determine that there is no segment of the wake-up signal corresponding to the UE in the second MO (the network device will not send the segment of the wake-up signal in the second MO, and the first segment is the last segment sent by the network device in the wake-up period), so that the UE does not listen to the segments of the wake-up signal in the second MO, so as to reduce the capability consumption of the UE and save energy.

[0032] In a possible implementation, the information related to the first segment includes a target number, the target number being a number of segments of the wake-up signal that the network device transmits in the listening period, and the first segment being one of the segments of the wake-up signal that the network device transmits in the listening period. In this way, in a case where the number of segments of the wake-up signal that the UE has received in the listening period reaches the target number, and the first segment is the last segment of the wake-up signal that the network device transmits in the listening period, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period, so as to reduce the capability consumption of the UE and save energy.

[0033] In a possible implementation, the first segment carries the target number. In this way, the UE that receives the first segment can obtain the target number according to the first segment, and in a case where the number of segments of the wake-up signal that the UE has received in the listening period reaches the target number, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period, so as to reduce the capability consumption of the UE and save energy.

[0034] In a possible implementation, the information related to the first segment includes a low-power synchronization signal (LPSS). In this way, the UE that receives the first segment can obtain the target number by receiving the low-power synchronization signal (LPSS), and in a case where the number of segments of the wake-up signal that the UE has received in the listening period reaches the target number, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period, so as to reduce the capability consumption of the UE and save energy.

[0035] In a possible implementation, the identification of the first segment or the information related to the first segment includes at least one of a superposition sequence corresponding to the first segment, a preamble sequence of the first segment, scrambling information corresponding to the first segment, and a target field in the first segment. In this way, the UE that receives the first segment can obtain the identification of the first segment or the information related to the first segment by analyzing at least one of the superposition sequence corresponding to the first segment, the preamble sequence of the first segment, the scrambling information corresponding to the first segment, and a newly defined field in the first segment, and the UE can determine whether to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period according to the identification of the first segment or the information related to the first segment, so as to reduce the capability consumption of the UE and save energy.

[0036] Exemplarily, the information related to the first segment can be an end symbol or a target number, wherein the end symbol is used to indicate that the first segment is the last segment sent by the network device in the listening period of the wake-up signal, and the target number is the number of segments sent by the network device in the listening period of the wake-up signal.

[0037] In a possible implementation, the segments of the wake-up signal correspond to a plurality of superposition sequences, the identification of the first segment or the information related to the first segment is carried in a first superposition sequence in the plurality of superposition sequences; or the segments of the wake-up signal correspond to a plurality of preamble sequences, the identification of the first segment or the information related to the first segment is carried in a first preamble sequence in the plurality of preamble sequences; or the segments of the wake-up signal correspond to a plurality of scrambling information, the identification of the first segment or the information related to the first segment is carried in a first scrambling information in the plurality of scrambling information. In this way, the UE can obtain the identification of the first segment or the information related to the first segment according to a mapping relationship between the identification of the first segment or the information related to the first segment and the first superposition sequence in the plurality of superposition sequences, or according to a mapping relationship between the identification of the first segment or the information related to the first segment and the first preamble sequence in the plurality of preamble sequences, or according to a mapping relationship between the identification of the first segment or the information related to the first segment and the first scrambling information in the plurality of scrambling information. Further, the UE can determine whether to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period according to the identification of the first segment or the information related to the first segment, so as to reduce the capability consumption of the UE and achieve energy saving.

[0038] In a possible implementation, the information related to the first segment includes a time domain offset, and the time domain offset is used to indicate a time length between a time when the UE receives the first segment and a starting time of the first listening occasion. In this way, different sizes of the time domain offset can map different information, and the UE receiving the first segment can determine whether to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period according to the time domain offset, so as to reduce the capability consumption of the UE and achieve energy saving.

[0039] In a possible implementation, the wake-up signal includes target bits, a quantity of the target bits is used to indicate that the wake-up signal includes a plurality of segments, the first segment is one of the plurality of segments, and each of the target bits corresponds to a UE in a set, and a value of each of the target bits is used to indicate whether the UE in the set performs a target operation. In this way, the UE receiving the first segment determines, according to the quantity of the target bits, that the wake-up signal includes the plurality of segments and a segment corresponding to the UE in the plurality of segments, and then the UE can determine, according to the first segment or information related to the first segment, whether there is the segment of the wake-up signal corresponding to the UE in a subsequent monitoring occasion (whether the UE does not receive the segment corresponding to the UE), and in a case where there is not the segment of the wake-up signal corresponding to the UE, the UE does not perform a process of monitoring the segment of the wake-up signal in a second monitoring occasion, thereby reducing the capability consumption of the UE and achieving energy saving.

The network device can also be a wireless controller in a cloud radio access network (cloud radio access network, CRAN) scenario, a centralized unit (centralized unit, CU), and / or a distributed unit (distributed unit, DU). The network device can communicate with the UE, or communicate with the UE through the relay station. The UE can communicate with multiple network devices of different technologies, for example, the UE can communicate with a network device supporting an LTE network, and can also communicate with a network device supporting a 5G network, and can also communicate with a network device supporting an LTE network and a network device of a 5G network in dual connectivity.

[0073] In the embodiments provided by the present application, the UE can be various forms, for example, a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a vehicle-mounted terminal device, a wireless terminal in self driving, a wireless terminal in remote medical treatment, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a wearable terminal device, and the like.

[0074] FIG. 1 is an example of a communication system architecture suitable for embodiments of the present application. The naming of network devices included in FIG. 1 is only a name, and the name does not constitute a limitation on the function of the network device itself. In 5G networks and future other networks, the above network devices can also be other names, and the embodiments of the present application do not make specific limitations thereon. For example, in a 6G network, part or all of the above network elements can continue to use the terminology in 5G, or may be other names, etc., which are uniformly described herein, and the following will not be described again.

[0075] In actual application scenarios, the UE can enter a sleep state to save the power consumption of the UE. In the sleep state, the UE can not listen to the PDCCH subframe, and when it is necessary to listen, the UE is woken up from the sleep state to listen to the PDCCH subframe to perform corresponding services. In actual application scenarios, the network device can wake up the UE by sending a wake-up signal to the UE.

[0076] FIG. 2 is a schematic diagram of a UE listening to a wake-up signal through a low power receiver. As shown in FIG. 2, the UE can include a main receiver (MR) and a low power receiver (LR). The low power receiver can be a low power wake up receiver (LP-WUR). In a case where a network device wakes up a UE in a sleep state, the network device can send a wake-up signal to the UE, which can be a LP-WUS or the like. This approach is suitable for power-sensitive, static, mobility-limited, and low-speed mobile UEs. The UE can receive the wake-up signal using the LP-WUR. Since the LP-WUR has much lower power consumption than the main receiver MR, listening to the wake-up signal by the LP-WUR and waking up the MR to start listening to a PDCCH subframe when the wake-up signal is detected can greatly reduce the power consumption of the UE and achieve the purpose of power saving.

[0077] FIG. 3a is a schematic diagram of a UE listening to a wake-up signal in a wake-up signal coverage. As shown in FIG. 3a, the ellipse represents an area on the ground, and the circular area in the ellipse is used to indicate the coverage of the wake-up signal. UEs in other areas outside the circular area usually have difficulty in accurately identifying signals sent by the network device. If the UE is in the wake-up signal coverage, the network device can enable the UE to listen to the wake-up signal. For example, the UE can use the LP-WUR to listen to the wake-up signal, and the MR can be in a sleep state. In other words, the UE can listen to the wake-up signal through the LP-WUR while the MR is in a sleep state. If the wake-up signal listened to by the UE contains relevant information of the UE (for example, identification information of the UE), the wake-up signal triggers the MR of the UE to listen to the PDCCH; otherwise, if the wake-up signal does not contain relevant information of the UE (for example, identification information of the UE), the UE does not start listening to the PDCCH.

[0078] Referring to FIG. 3b, a schematic diagram of a structure of a wake-up signal is shown. The wake-up signal is composed of a payload, wherein the payload of the wake-up signal is used to carry relevant information of the UE. The UE can receive one or more subcarriers of the wake-up signal in a frequency band dedicated to the wake-up signal, so that the UE demodulates the wake-up signal according to the one or more subcarriers, and determines whether to wake up the UE according to the payload of the wake-up signal.

[0079] Alternatively, referring to FIG. 3c, another structure of a wake-up signal provided by an embodiment of the present application is shown. The wake-up signal is composed of a payload and a cyclic redundancy check (CRC), wherein the CRC is used to check the payload of the wake-up signal. Specifically, the UE can check the payload according to the CRC of the wake-up signal, and if the result of the check is correct, the UE can determine whether to wake up the UE according to the payload of the wake-up signal.

[0080] Alternatively, referring to FIG. 3d, another structure of a wake-up signal provided by an embodiment of the present application is shown. The wake-up signal is composed of a payload and a preamble sequence, wherein the preamble sequence is the starting part of the wake-up signal, and the preamble sequence is a specific sequence dedicated to the wake-up signal, used to identify the signal as a wake-up signal. Specifically, the UE can determine whether the signal is a wake-up signal according to the preamble sequence of the signal, and then, if the signal is a wake-up signal, the UE can determine whether to wake up the UE according to the payload.

[0081] Alternatively, referring to FIG. 3e, another structure of a wake-up signal provided by an embodiment of the present application is shown. The wake-up signal is composed of a payload, a preamble sequence and a CRC, which can be referred to the related description of FIG. 3c and FIG. 3d above, and will not be described again.

[0082] In actual application scenarios, if the network device sends multiple different LP-WUSs using different code points for each UE in the coverage of the signal, each LP-WUS is used to wake up one or a group of UEs, which makes each UE will listen to whether there is a LP-WUS used to wake up the UE in all monitoring occasions (MO) in each listening period, thereby causing the energy consumption of the UE to be at a high level. The code point refers to the encoding of a character, and different code points can be used to indicate different characters, so that the UE can determine whether to wake up the UE according to the LP-WUS by receiving the code point information carried by the LP-WUS.

[0083] To this end, the present application proposes that, in the communication system shown in FIG. 1, the network device can segment the entire payload required to be carried by the LP-WUS, each segment carrying information of part of the payload, the payload information carried by each segment being used to wake up part of the UEs within the signal coverage of the network device, and different segments being used to wake up different UEs. In this way, the network device can send different segments of the wake-up signal in different MOs included in each listening period. Correspondingly, the UE within the signal coverage of the network device can listen to the segment of the LP-WUS corresponding to the UE in one or more MOs in the listening period, so as to determine whether to wake up the MR to start listening to the PDCCH subframe by using the payload information carried in the listened segment.

[0084] It can be understood that, if the UE listens to the segments of the LP-WUS in all MOs in a listening period, this will cause the energy consumption of the UE to be at a high level.

[0085] To this end, the UE can reduce the energy consumption by listening to the segments of the LP-WUS in part of the MOs.

[0086] In a specific implementation, the UE can receive a first segment of the LP-WUS in a first MO of the LP-WUS, wherein the first MO is one of the MOs included in a listening period, and the first MO is followed by a second MO (and even a third MO, etc.) in the listening period. Moreover, the UE can also determine, according to the first segment or information related to the first segment, whether there is a segment corresponding to the UE in the second MO of the LP-WUS (the payload in the segment is used to indicate whether to wake up the UE). For example, the information related to the first segment can be information carried in the first segment, information sent by the network device to the UE alone, or a time domain offset, etc., wherein the time domain offset is used to indicate the time length between the time when the UE receives the first segment and the start time of the first MO. In this way, if the UE determines, according to the first segment or the information related to the first segment, that there is no segment corresponding to the UE in the second MO of the LP-WUS, the UE can not listen to the segments of the LP-WUS in the second MO, for example, the LR in the UE can enter a sleep state in the second MO (and subsequent MOs) in the current listening period.

[0087] Since in the process that the network device transmits one or more segments of the LP-WUS to the UE in the signal coverage range, the UE can determine whether there is a segment of the LP-WUS corresponding to the UE in one or more MOs after the first MO according to the first segment or information related to the first segment, and in the case that there is no segment of the LP-WUS corresponding to the UE, the UE does not perform the process of listening to the segment of the LP-WUS in the second MO, so that the number of MOs used by the UE to listen to the signal can be reduced, thereby reducing the energy consumption of the UE in the second MO (and subsequent listening occasions), and energy saving is achieved.

[0088] In order to make the technical solutions of the present application clearer and easier to understand, the following will be exemplarily described in combination with FIG. 4, taking the application to the communication system shown in FIG. 1 as an example.

[0089] Referring to FIG. 4, a communication method provided by an embodiment of the present application is shown. As shown in FIG. 4, the flow of the communication method includes the following steps:

[0090] S401: A network device generates a first segment of a wake-up signal.

[0091] The wake-up signal can be the above-mentioned LP-WUS, or other types of wake-up signals, which are not limited.

[0092] Generally, after the network device wakes up the UE through the wake-up signal (specifically, a segment of the wake-up signal), the UE can perform a target operation. Exemplarily, if the UE is in a connected (RRC-connected) state (a communication connection has been established between the UE and the network device), the target operation performed by the UE can be an operation of listening to a PDCCH subframe. In addition, if the UE is in an idle (RRC-idle) state or an inactive (RRC-inactive) state, the target operation performed by the UE can be an operation of listening to a paging message in a paging occasion (PO), etc. In the present embodiment, the target operation performed by the UE after being woken up is not limited.

[0093] In actual application scenarios, the number of UEs located in the signal coverage range of the network device can be large, which makes the wake-up signal need to carry more payload information to indicate whether each UE needs to be woken up. However, the payload information that can be carried by the wake-up signal sent by the network device at a time is limited, therefore, the network device can segment the entire payload required to be carried by the wake-up signal, so that each segment of the wake-up signal can carry part of the entire payload, and different segments of the wake-up signal can be used to wake up different UEs.

[0094] Based on this, the network device can generate a first segment of the wake-up signal, where the first segment carries part of the total payload required to be carried by the wake-up signal, and the first segment is used to wake up one or more UEs corresponding to the part of the payload carried by the first segment.

[0095] Exemplarily, the total payload required to be carried by the wake-up signal can be a plurality of bits, which are referred to as target bits below for the convenience of description and differentiation. Each of the target bits corresponds to a UE in a set. Exemplarily, a plurality of UEs in the signal coverage of the network device can be divided into one or more sets, and each set includes at least one UE. For example, the network device can cluster the plurality of UEs in the signal coverage according to the geographical positions of the UEs (for example, by using an aggregation algorithm to cluster the plurality of UEs), thereby obtaining a plurality of sets, where the UEs in each set are close to each other in geographical position, and the UEs in different sets are far from each other in geographical position. The set to which a UE belongs can be a subgroup, a group, or another set including at least one UE in the communication network, which is not limited.

[0096] The value of each of the target bits can be used to indicate whether the UEs in a set perform a target operation. For example, if the value of one of the target bits is "1", it can be used to indicate that each UE in the set corresponding to the bit performs the target operation (for example, indicating each UE to start monitoring a PDCCH subframe); if the value of the bit is "0", it can be used to indicate that each UE in the set does not perform the target operation (for example, indicating each UE to continue to maintain a sleep state), which is not limited.

[0097] For the target bits required to be carried by the wake-up signal, the network device can generate a plurality of segments of the wake-up signal, each segment of the wake-up signal carries part of the target bits, and the number of the part of the target bits that can be carried by each segment does not exceed the upper limit of the number of bits that can be carried by the wake-up signal that can be sent by the network device at a time.

[0098] In a specific implementation, the network device can determine the number of segments of the wake-up signal to be generated according to the segment threshold, that is, determine the number of segments of the target bits. For example, if the number of bits included in the target bits is not higher than the segment threshold, the total number of segments of the wake-up signal to be generated by the network device is 1; if the number of bits included in the target bits is higher than the segment threshold and not higher than twice the segment threshold, the total number of segments of the wake-up signal to be generated by the network device is 2; if the number of bits included in the target bits is higher than twice the segment threshold and not higher than three times the segment threshold, the total number of segments of the wake-up signal to be generated by the network device is 3, and so on. It should be noted that the segment threshold can be equal to or less than the number of bits that can be carried by a signal sent by the network device at a time, and the number of bits (that is, part of the target bits) carried by different segments of the wake-up signal can be equal or not equal.

[0099] For example, FIG. 5 is a schematic diagram of segmenting the payload carried by the wake-up signal according to an embodiment of the present application. As shown in FIG. 5, the number of target bits is 16, and the segment threshold is 4. Based on this, the network device divides the target bits into 4 segments, and each segment includes 4 bits. For example, segment 2 includes bits 5 to 8 in the target bits. Accordingly, the total number of segments of the wake-up signal generated by the network device is 4. The value of each bit is used to indicate whether the UEs in a set perform a target operation. For example, the value of the 7th bit is "1", which is used to indicate that the UEs in a set corresponding to the 7th bit perform a target operation.

[0100] In addition, the network device can segment the target bits based on other segmenting rules, and the number of bits included in different segments of the target bits can be equal or not equal, which is not limited herein.

[0101] For example, the network device can indicate to the UE that the wake-up signal includes multiple segments, and indicate to the UE the segment corresponding to the UE in the multiple segments. In this embodiment, the following examples are provided in which the network device indicates to the UE that the wake-up signal includes multiple segments, and indicates to the UE the segment corresponding to the UE in the multiple segments.

[0102] In a first possible implementation example, the network device can explicitly indicate to the UE. Specifically, the network device can send indication information to the UE, where the indication information is used to indicate to the UE that the wake-up signal includes multiple segments and the segment corresponding to the UE in the multiple segments.

[0103] Exemplarily, the indication information can comprise a correspondence between the identity of each segment of the wake-up signal and a set comprising at least one UE, so that the UE determines the segment corresponding to the UE in the plurality of segments according to the correspondence. For example, referring to FIG. 5, the indication information can comprise a correspondence between segment 2 and a set corresponding to bit 7, so that the UE in the set corresponding to bit 7 determines, according to the indication information, that the corresponding segment is segment 2 (i.e., the identity of the segment is “2”).

[0104] Alternatively, the indication information can comprise the identity of each segment of the wake-up signal and the number of bits contained in each segment, so that the UE determines the segment corresponding to the UE in the plurality of segments according to the identity of each segment and the number of bits contained in each segment. For example, referring to FIG. 5, the indication information can comprise a correspondence between the identity of each segment and the number of bits contained in each segment, i.e., the identity of the four segments of segment 1 (i.e., the identity of the segment is “1”, and the rest of the segments are similar), segment 2, segment 3, and segment 4, and the number of bits contained in each segment is 4. Assuming that the set to which the UE belongs corresponds to bit 7 (i.e., the 7th bit in the entire payload), since the bit number “7” of bit 7 is greater than the number of bits “4” contained in the first segment (segment 1), and the bit number “7” is less than the sum “8” of the number of bits contained in the first segment and the second segment (i.e., segment 2), the UE in the set corresponding to bit 7 can determine, according to the indication information, that the corresponding segment of the UE is segment 2.

[0105] In addition, there can be several different implementation manners for the network device to send the indication information to the UE.

[0106] In a first implementation manner, the UE can establish a radio resource control (RRC) connection with the network device, i.e., the UE is in a connected state, so that the network device can send an RRC message to the UE, and the RRC message carries the indication information. Correspondingly, the UE can parse the indication information from the received RRC message.

[0107] In a second implementation manner, the UE can be in an idle state (RRC-idle state) or an inactive state (RRC-inactive state). At this time, the network device can broadcast a system information block 1 (SIB1), and the SIB1 can carry the indication information. Correspondingly, the UE can parse the indication information from the system message of the received SIB1.

[0108] In a third implementation manner, the UE can be in an RRC-connected state. The network device can send a medium access control-control element (MAC-CE) message to the UE, and the MAC-CE message can carry the indication information. Accordingly, the UE can parse the indication information from the received MAC-CE message.

[0109] In a fourth implementation manner, the UE can be in an RRC-connected state or an RRC-inactive state. The network device can send a downlink control information (DCI) message to the UE, and the DCI message can carry the indication information. Accordingly, the UE can parse the indication information from the received DCI message.

[0110] It should be noted that the implementation manner of sending the indication information by the network device to the UE is only some exemplary description, and the network device can also send the indication information to the UE in other manners, which is not limited.

[0111] In a second possible implementation example, the network device can implicitly indicate the UE.

[0112] Specifically, the segmentation rule of the target bits can be synchronized between the network device and the UE, so that the network device can determine, according to the segmentation rule of the target bits and the number of the target bits, that the wake-up signal includes multiple segments and a segment corresponding to the UE in the multiple segments. Meanwhile, the UE can also determine, according to the same segmentation rule of the target bits and the number of the target bits, that the wake-up signal includes multiple segments and a segment corresponding to the UE in the multiple segments.

[0113] For example, referring to FIG. 5, the network device and the UE can segment the target bits according to the segmentation threshold. Based on this, since the segmentation threshold is 4 and the number of the target bits is 16, the network device and the UE can divide the target bits into 4 segments, wherein bit 7 belongs to the second segment, and the UE in a set corresponding to bit 7 can determine that it corresponds to the second segment.

[0114] For example, the network device can previously send the number of the target bits and the segmentation rule of the target bits to the UE. For brevity, the related description of sending the indication information by the network device to the UE is not repeated here.

[0115] It should be noted that the network device can also indicate to the UE that the wake-up signal contains multiple segments or indicate to the UE the segment corresponding to the UE through other implementation examples, which are not limited.

[0116] S402: The network device sends a first segment of the wake-up signal to the UE in a first MO, where the first MO is one of multiple MOs included in one listening period, and the multiple MOs further include a second MO, which is located after the first MO in the time domain.

[0117] For example, the UE can listen to the MO to receive the segment of the wake-up signal sent by the network device. One listening period can include multiple MOs, for example, referring to FIG. 6, one listening period can include a first MO and a second MO, and the second MO is located after the first MO in the time domain. In actual application scenarios, more than 3 (including 3) MOs can also be included in one listening period, which are not limited.

[0118] The network device can send the first segment of the wake-up signal to the UE in the first MO, and correspondingly, the UE can receive the first segment of the wake-up signal sent by the network device in the first MO. For example, referring to FIG. 6, which is a schematic diagram of the network device transmitting the segment of the wake-up signal in the MO in the listening period according to an embodiment of the present application. The network device can send segment 2 (i.e., the first segment described above) in FIG. 5 to the UE in the first MO, and correspondingly, the UE can listen to the signal in the first MO to receive the segment 2. It should be noted that the starting time of the network device sending the segment of the wake-up signal to the UE can be the starting time of the first MO, or other time in the first MO, which is not limited.

[0119] Optionally, the network device can repeatedly send the first segment of the wake-up signal in multiple MOs. For example, the network device can adjust the number of MOs for sending the segment corresponding to the UE according to the capability of the UE receiving the wake-up signal. For example, if the channel quality between the UE and the network device is worse, the capability of the UE receiving the segment of the wake-up signal is lower, and correspondingly, the number of MOs for sending the segment corresponding to the UE is higher. The network device can also adjust the number of MOs for sending the segment according to the number of bits carried by the segment, for example, the more the number of bits of the segment, the more the number of sets that the segment needs to indicate, and correspondingly, the number of MOs for sending the segment is higher.

[0120] S403: The UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the first segment, where the first segment carries an identifier of the first segment.

[0121] S404: In a case where the identifier of the first segment indicates that there is no segment of the wake-up signal corresponding to the UE in the second MO, the UE does not listen to the segments of the wake-up signal in the second MO.

[0122] In the process that the network device sends one or more segments of the wake-up signal to the UE, the UE can continuously listen to the segments of the wake-up signal sent by the network device in the MO through the LR. However, there can be no segment of the wake-up signal corresponding to the UE in the subsequent MO, and the UE continues to receive the segments of the wake-up signal in the subsequent MO can cause the UE to have a high energy consumption level.

[0123] Therefore, after the UE receives the first segment of the wake-up signal in the first MO, the UE can determine, according to the first segment or information related to the first segment, whether there is a segment corresponding to the UE in a second MO of the wake-up signal located in the time domain after the first MO. Further, if the UE determines, according to the first segment or information related to the first segment, that there is no segment corresponding to the UE in the second MO of the wake-up signal, the UE does not listen to the segments of the wake-up signal in the second MO.

[0124] In this way, the number of MOs used by the UE to listen to the signal is reduced, so that the energy consumption of the UE in the second MO and subsequent MOs can be reduced, and energy saving is achieved.

[0125] Exemplarily, in the process that the network device sends one or more segments of the wake-up signal to the UE, the UE can continuously listen to the segments of the wake-up signal sent by the network device in the MO through the LR, at this time the LR of the UE is in the running state. However, if the UE determines, according to the first segment or information related to the first segment, that there is no segment corresponding to the UE in the second MO of the wake-up signal, the LR can enter the sleep state from the running state, and accordingly, the LR of the UE can not continue to listen to the segments of the wake-up signal sent by the network device in the second MO.

[0126] In this embodiment, the first segment can include an identifier of the first segment. Then, the UE can determine whether the identifier of the first segment is consistent with the identifier of the segment corresponding to the set to which the UE belongs, and in a case where the identifier of the first segment is consistent with the identifier of the segment corresponding to the set to which the UE belongs, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MOs (including the second MO and other MOs) of the listening period, so as to reduce the energy consumption of the UE.

[0127] It should be noted that, if the identifier of the first segment is consistent with the identifier of the segment corresponding to the set to which the UE belongs, that is, the first segment is the segment of the wake-up signal corresponding to the UE, the UE can determine whether to perform a target operation according to a segment rule of the wake-up signal, by using part of bits of a target bit carried by the segment.

[0128] For example, referring to FIG. 5, it is assumed that the identifier of the first segment is 2 (i.e., the first segment is segment 2 shown in FIG. 5) and the payload carried by the first segment is "0010". For the 1st bit in the segment (i.e., bit 5 in FIG. 5), since the value of the bit is "0", the UEs in the set corresponding to the bit can determine not to perform the target operation. For the 2nd bit in the segment (i.e., bit 6 in FIG. 5), since the value of the bit is "0", the UEs in the set corresponding to the bit can determine not to perform the target operation. For the 3rd bit in the segment (i.e., bit 7 in FIG. 5), since the value of the bit is "1", the UEs in the set corresponding to the bit can determine to perform the target operation. For the 4th bit in the segment (i.e., bit 8 in FIG. 5), since the value of the bit is "0", the UEs in the set corresponding to the bit can determine not to perform the target operation.

[0129] Further, the network device can not need to send all the segments of the wake-up signal to the UE. Specifically, a segment of the wake-up signal carries part of the target bits, and the value of each bit carried by the segment is used to indicate whether the UEs in a set perform the target operation. Therefore, if the UEs in the set corresponding to each bit carried by the segment do not perform the target operation, the network device can not need to send the segment. In this way, in the case where the identifiers of the segments included in the wake-up signal are arranged in ascending order, if the identifier of the first segment is greater than the identifier of the segment corresponding to the set to which the UE belongs, the segment corresponding to the UE is not sent by the network device, i.e., the UEs in the set corresponding to each bit carried by the segment do not perform the target operation, and further, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MOs of the monitoring period, thereby reducing the capability consumption of the UE. Alternatively, in the case where the identifiers of the segments included in the wake-up signal are arranged in descending order, if the identifier of the first segment is less than the identifier of the segment corresponding to the set to which the UE belongs, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MOs of the monitoring period.

[0130] For example, referring to FIG. 5, in the case where the identifiers of the segments included in the wake-up signal are arranged in ascending order, if the UEs in the set corresponding to bit 3 receive segment 2, since the identifier of the segment corresponding to the UEs in the set is "1" which is less than the identifier "2" of the received segment, the UEs in the set can determine that segment 1 is not sent by the network device, i.e., the UEs in the set corresponding to each bit carried by segment 1 do not perform the target operation, and further, the UEs in the set do not need to continue to receive the segments of the wake-up signal in the subsequent MOs.

[0131] In this embodiment, the following implementation examples in which the identifier of the first segment is included in the first segment are provided.

[0132] In a first implementation example, the identification of the first segment can be included in an overlaid sequence corresponding to the first segment. For example, the network device can modulate the segments of the wake-up signal with different overlaid sequences, e.g., the network device can modulate different overlaid sequences onto the carriers of the segments of the wake-up signal. The sequence used to modulate the segments of the wake-up signal can be referred to as an overlaid sequence. This modulation can also be referred to as superimposing the sequence on the segments of the wake-up signal.

[0133] The segments of the wake-up signal can correspond to a plurality of overlaid sequences, and the overlaid sequence superimposed on the first segment can be a first overlaid sequence among the plurality of overlaid sequences. In this way, superimposing different overlaid sequences can be used to carry information, i.e., the identification of the first segment can be included in the first overlaid sequence corresponding to the first segment. For example, the network device can map the value of the identification of the first segment to the first overlaid sequence, and superimpose the first overlaid sequence on the first segment, so that the UE determines the value of the identification corresponding to the first overlaid sequence according to the first overlaid sequence superimposed on the first segment, i.e., the value of the identification of the first segment, using the mapping relationship between the overlaid sequence and the value of the identification.

[0134] In a second implementation example, the identification of the first segment can be included in a preamble sequence of the first segment. For example, the structure of the first segment of the wake-up signal can be the structure shown in FIG. 3d or FIG. 3e, i.e., the first segment of the wake-up signal includes a preamble sequence. FIG. 7 is a schematic diagram of a preamble sequence of a segment of a wake-up signal according to an embodiment of the present application. As shown in FIG. 7, the preamble sequence is the starting portion in the segment of the wake-up signal (located before the payload of the segment), and the segment of the wake-up signal can use a plurality of preamble sequences, so that different preamble sequences can be used to carry different information. Then, the preamble sequence of the first segment can be a first preamble sequence among the plurality of preamble sequences, and the identification of the first segment can be included in the first preamble sequence of the first segment. For example, the network device can map the value of the identification of the first segment to the first preamble sequence, and carry the first preamble sequence in the starting portion of the first segment, so that the UE determines the value of the identification corresponding to the first preamble sequence according to the first preamble sequence of the first segment, i.e., the value of the identification of the first segment, using the mapping relationship between the preamble sequence and the value of the identification.

[0135] In addition, in combination with the first implementation example, the network device can also superimpose different superimposed sequences on the segmented preamble sequence, and the identifier of the first segment can also be included in the first superimposed sequence corresponding to the preamble sequence of the first segment. For example, the network device can map the value of the identifier of the first segment to the first superimposed sequence, and superimpose the first superimposed sequence on the preamble sequence of the first segment, so that the UE determines the value of the identifier corresponding to the first superimposed sequence according to the first superimposed sequence superimposed on the preamble sequence of the first segment, and determines the value of the identifier of the first segment according to the mapping relationship between the superimposed sequence and the value of the identifier.

[0136] Alternatively, the identifier of the first segment can be included in part of the bits in the preamble sequence of the segment of the wake-up signal, and the specific implementation manner in which the identifier of the first segment is included in the preamble sequence is not limited in this embodiment.

[0137] In the third implementation example, the identifier of the first segment can be included in the scrambling information corresponding to the first segment. For example, the structure of the first segment of the wake-up signal can be the structure shown in FIG. 3c or FIG. 3e, the identifier of the first segment can be included in the scrambling information of the CRC of the first segment, or the identifier of the first segment can be included in the scrambling information of the data part of the first segment. For example, the segments of the wake-up signal can correspond to multiple scrambling information, and the scrambling information of the first segment can be the first scrambling information in the multiple scrambling information. The network device can perform XOR calculation on the CRC of the first segment and the first scrambling information to obtain the scrambled CRC, and then the UE can perform CRC calculation on the data part of the first segment, and perform XOR calculation on the calculated CRC and the scrambled CRC to obtain the first scrambling information. Alternatively, the network device can perform XOR calculation on the data part of the first segment and the first scrambling information to obtain the scrambled data, and then the UE performs XOR operation on the scrambled data and the multiple scrambling information respectively, and performs CRC calculation on the results of the XOR operation, and compares the calculated CRC with the CRC in the first segment, so that the UE can determine the first scrambling information. Based on this, different scrambling information can be used to carry information, that is, the identifier of the first segment can be included in the first scrambling information corresponding to the first segment. For example, the network device can map the value of the identifier of the first segment to the first scrambling information, and scramble the first segment by using the first scrambling information, so that the UE determines the value of the identifier corresponding to the first scrambling information according to the first scrambling information corresponding to the first segment, and determines the value of the identifier of the first segment according to the mapping relationship between the scrambling information and the value of the identifier.

[0138] In a fourth implementation example, referring to FIG. 8, a schematic diagram of a target field in a segment of a wake-up signal is shown. The identity of the first segment can be included in the target field in the first segment. For example, based on the LP-WUS defined in the 3GPP Release 18 communication standard or other existing communication standards, the network device can add a target field in the first segment of the LP-WUS, wherein the identity of the first segment is included in the target field, so that the UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the target field of the first segment.

[0139] In addition, the identity of the first segment can also be carried in the first segment according to other implementation manners, which are not limited.

[0140] In the embodiment described above in FIG. 4, the first segment includes the identity of the first segment, and the UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the identity of the first segment in the first segment. In other embodiments, the UE can determine whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to information related to the first segment, wherein the information related to the first segment can be a time domain offset, and the time domain offset can be used to indicate the identity of the first segment.

[0141] The following is an exemplary description taking the application to the communication system shown in FIG. 1 as an example.

[0142] Referring to FIG. 9, a communication method provided by an embodiment of the present application is shown. As shown in FIG. 9, the flow of the communication method includes the following steps:

[0143] S901: The network device generates a first segment of a wake-up signal.

[0144] In this embodiment, the specific implementation of step S901 can be described with reference to the related description of step S401 in the embodiment shown in FIG. 4, and for brevity, it will not be repeated here.

[0145] S902: The network device determines a time domain offset, wherein the time domain offset is used to indicate the time length between the time when the UE receives the first segment and the starting time of the first MO, and the time domain offset is also used to indicate whether there is a segment of the wake-up signal corresponding to the UE in the second MO.

[0146] FIG. 10 is a schematic diagram of a time domain offset according to an embodiment of the present application. As shown in FIG. 10, the network device can not send the first segment of the wake-up signal to the terminal at the starting moment of the first MO, and thus the network device can map the identifier of the first segment to a time domain offset, where the time domain offset is used to indicate the time length between the moment when the terminal receives the first segment and the starting moment of the first MO.

[0147] In actual application scenarios, the time domain offset can be represented by the time length between the moment when the terminal receives the first segment and the starting moment of the first MO, or can be represented by the number of slots, the number of frames, the number of symbols, etc. between the two moments, which is not limited, so that different sizes of time domain offsets can indicate different segment identifiers, which enables the terminal to determine the identifier of the segment according to the time domain offset, and further determine whether there is a segment of the wake-up signal corresponding to the terminal in the second MO according to the identifier of the segment.

[0148] S903: The network device sends, according to the time domain offset, a first segment of the wake-up signal to the terminal in the first MO, where the first MO is one of the MOs included in a listening period, and the MOs further include the second MO, and the second MO is located after the first MO in the time domain.

[0149] In this embodiment, the specific implementation of step S903 can be described with reference to the related description of step S402 in the embodiment of FIG. 4 described above. For brevity, the description is not repeated here. In the first MO, the network device can delay sending the first segment of the wake-up signal for a period of time, and the time length of the delay is the time length indicated by the time domain offset.

[0150] S904: The terminal determines, according to the time domain offset, whether there is a segment corresponding to the terminal in the second MO of the wake-up signal, where the time domain offset is used to indicate the identifier of the first segment.

[0151] S905: In the case where the identifier of the first segment indicates that there is no segment of the wake-up signal corresponding to the terminal in the second MO, the terminal does not listen to the segment of the wake-up signal in the second MO.

[0152] After the UE receives the first segment of the wake-up signal in the first MO, the UE can determine the identity of the first segment according to the time domain offset, and in this embodiment, the identity of the first segment can be used not only to distinguish segments, but also to indicate whether there is a segment of the wake-up signal corresponding to the UE in the second MO after the first MO in the time domain. Furthermore, the UE can determine whether to continue receiving segments of the wake-up signal in the second MO according to the identity of the first segment, that is, in the case where the identity of the first segment indicates that there is no segment of the wake-up signal corresponding to the UE in the second MO, the UE does not listen to the segments of the wake-up signal in the second MO. The specific implementation of the UE determining that there is no segment of the wake-up signal corresponding to the UE in the second MO according to the identity of the first segment can be referred to the description of the related part in the embodiment shown in FIG. 4, and will not be described here.

[0153] In this way, the UE can not listen to signals in the second MO and subsequent MOs according to the identity of the first segment, which can reduce the number of MOs used by the UE to listen to signals, thereby reducing the energy consumption of the UE and achieving energy saving.

[0154] In a further possible implementation, different time domain offsets can be used to carry different information. For example, the network device can establish a mapping relationship between the identity of the segment and the time domain offset, and different sizes of the time domain offset are mapped to different segment identities. The value of the segment identity can be the value of the time domain offset, or can be the ratio of the time domain offset to a fixed time slot or time frame, etc. Furthermore, the UE can determine the time domain offset according to the time length between the time when the first segment is received and the starting time of the first MO, and then determine the identity of the first segment according to the correspondence between the time domain offset and the segment identity. For example, if the time domain offset is represented by the number of time slots, segment 1 shown in FIG. 5 can be mapped to a time domain offset of 1 time slot, segment 2 can be mapped to a time domain offset of 2 time slots, etc.

[0155] In this embodiment, for other implementation modes of steps S904 and S905, refer to the description of the related part of steps S403 and S404 in the embodiment shown in FIG. 4, and will not be described here for brevity.

[0156] In the embodiment described in FIG. 9, the UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the time domain offset, and the time domain offset is used to indicate the identity of the first segment. In other embodiments, the information related to the first segment can be an end symbol, and the end symbol is carried in the first segment. Furthermore, the UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the end symbol.

[0157] The following will be described by taking the application to the communication system shown in FIG. 1 as an example.

[0158] Referring to FIG. 11, a communication method provided by an embodiment of the present application is shown. As shown in FIG. 11, the flow of the communication method includes the following steps:

[0159] S1101: The network device generates a first segment of the wake-up signal.

[0160] In the embodiment, the specific implementation of step S1101 can be described with reference to the related part of step S401 in the embodiment shown in FIG. 4, and will not be described here for brevity.

[0161] S1102: The network device sends the first segment of the wake-up signal to the UE in the first MO, wherein the first MO is one of a plurality of MOs included in a listening period, and the plurality of MOs further include a second MO, and the second MO is located after the first MO in the time domain.

[0162] In the embodiment, the specific implementation of step S1102 can be described with reference to the related part of step S402 in the embodiment shown in FIG. 4, and will not be described here for brevity.

[0163] S1103: The UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the end symbol, wherein the end symbol is carried in the first segment, and the end symbol is used to indicate that the first segment is the last segment sent by the network device in the listening period of the wake-up signal.

[0164] S1104: In the case that the end symbol indicates that there is no segment of the wake-up signal corresponding to the UE in the second MO, the UE does not listen to the segment of the wake-up signal in the second MO.

[0165] The UE can determine whether to continue receiving the segment of the wake-up signal in the second MO according to whether the end symbol is contained in the received segment of the wake-up signal, that is, in the case that the first segment includes the end symbol, the UE can determine that there is no segment of the wake-up signal corresponding to the UE in the second MO (the network device will not send the segment of the wake-up signal in the second MO, and the first segment is the last segment sent by the network device in the listening period), so that the UE does not listen to the segment of the wake-up signal in the second MO.

[0166] In this way, the network device and the UE can use the end symbol to reduce the number of MOs used by the UE to listen to the signal, so as to reduce the energy consumption of the UE in the second MO and subsequent MOs, and achieve energy saving.

[0167] For example, referring to FIG. 5, the network device does not need to send the segment 1 and the segment 4, because if the UEs in the set corresponding to each bit carried by the segment do not perform the target operation, the network device does not need to send the segment. If the UEs in the set corresponding to the bit 14 receive the segment 3, because the segment 3 contains the end symbol, the UEs in the set can determine that the segment 3 is the last segment sent by the network device in the listening period, and further, the UEs in the set can determine that the segment 4 will not be sent by the network device, i.e., the UEs in the set corresponding to each bit carried by the segment 4 do not perform the target operation, and therefore, the UEs in the set do not need to continue to receive the segments of the wake-up signal in the subsequent MO.

[0168] It should be noted that the end symbol can be carried in the first preamble sequence of the first segment, wherein the first preamble sequence can be a specific preamble sequence of the multiple preamble sequences corresponding to the segments of the wake-up signal. For example, if the first segment is the last segment sent by the network device in the listening period, the first preamble sequence carried by the first segment is the specific preamble sequence corresponding to the end symbol. Thus, the UEs can parse the first preamble sequence from the first segment, and determine that the first segment is the last segment sent by the network device in the listening period by using the first preamble sequence. In actual application scenarios, if the segment received by the UEs is not the last segment sent by the network device in the listening period, the preamble sequence parsed from the received segment can be used to indicate that the segment is not the last segment, i.e., the network device will continue to send the next segment of the wake-up signal in the listening period.

[0169] Alternatively, the end symbol can be carried in the first superposition sequence of the first segment, wherein the first superposition sequence can be a specific superposition sequence of the multiple superposition sequences corresponding to the segments of the wake-up signal. That is, part of the superposition sequences can be used to indicate that the segment of the wake-up signal currently received by the UEs is the last segment sent by the network device in the listening period, and another part of the superposition sequences can be used to indicate that the segment of the wake-up signal currently received by the UEs is not the last segment.

[0170] Alternatively, the end symbol can be carried in the first scrambling information of the first segment, wherein the first scrambling information can be a specific scrambling information of the multiple scrambling information corresponding to the segments of the wake-up signal. That is, part of the scrambling information can be used to indicate that the segment of the wake-up signal currently received by the UEs is the last segment sent by the network device in the listening period, and another part of the scrambling information can be used to indicate that the segment of the wake-up signal currently received by the UEs is not the last segment.

[0171] Alternatively, the end marker can be carried in a target field in the first segment (segment of the wake-up signal defined in the R18 communication standard or other existing communication standard).

[0172] In addition, the end marker can also be carried in the first segment according to other implementation manners, which are not limited.

[0173] In this embodiment, for other implementation manners of steps S1103 and S1104, please refer to the description of the related parts of steps S403 and S404 in the embodiment of FIG. 4, which will not be repeated here for brevity.

[0174] In the embodiment of FIG. 11, the UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the end marker carried in the first segment. In other embodiments, the UE can determine whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to information related to the first segment, wherein the information related to the first segment can be the end marker, and the end marker is sent by the network device to the UE separately and is not carried in the first segment.

[0175] Next, with reference to FIG. 12, a communication method provided by an embodiment of the present application is described by way of example.

[0176] Referring to FIG. 12, a communication method provided by an embodiment of the present application is shown. As shown in FIG. 12, the flow of the communication method includes the following steps:

[0177] S1201: The network device generates a first segment of a wake-up signal.

[0178] In this embodiment, for the specific implementation manner of step S1201, please refer to the description of the related parts of step S401 in the embodiment of FIG. 4, which will not be repeated here for brevity.

[0179] S1202: The network device sends the first segment of the wake-up signal to the UE in the first MO, wherein the first MO is one of a plurality of MOs included in a listening period, and the plurality of MOs further includes a second MO, and the second MO is located after the first MO in the time domain.

[0180] In this embodiment, for the specific implementation manner of step S1202, please refer to the description of the related parts of step S402 in the embodiment of FIG. 4, which will not be repeated here for brevity.

[0181] S1203: The network device sends an end marker in the first MO.

[0182] The network device can send an end symbol to the UE, where the end symbol is used to indicate that the first segment is the last segment sent by the network device in the listening period of the wake-up signal.

[0183] Based on this, if the UE receives the end symbol in the first MO, the UE does not need to continue to receive the segments of the wake-up signal in the second MO and subsequent MOs of the listening period, which reduces the capability consumption of the UE and achieves energy saving.

[0184] Specifically, as shown in FIG. 13, which is a schematic diagram of a network device sending an end symbol in a first MO according to an embodiment of the present application, the network device can send a first segment in a part of the time period of the first MO, and send an end symbol in another part of the time period of the first MO.

[0185] S1204: The UE receives the end symbol in the first MO, and determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the end symbol.

[0186] S1205: In a case where the end symbol indicates that there is no segment of the wake-up signal corresponding to the UE in the second MO, the UE does not listen to the segments of the wake-up signal in the second MO.

[0187] In this embodiment, the specific implementation of steps S1204 and S1205 can be described with reference to the related description of steps S1103 and S1104 in the embodiment of FIG. 4 described above. For brevity, the description is not repeated here.

[0188] In addition, the first segment can also carry an identifier of the first segment, and then the UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the identifier of the first segment and the end symbol. The identifier of the first segment can be carried in a superposition sequence corresponding to the first segment, a preamble sequence of the first segment, scrambling information corresponding to the first segment, or a target field in the first segment (a segment of the wake-up signal defined in the R18 communication standard or other existing communication standards).

[0189] Alternatively, the identifier of the first segment can be carried in a time domain offset.

[0190] Alternatively, the identifier of the first segment can be carried in the end symbol. In a specific implementation, the network device can send different end symbols to the UE, and the end symbol of the first segment can be a first end symbol of the different end symbols. The different end symbols can be used to carry information, that is, the identifier of the first segment can be carried in the end symbol sent by the network device to the UE. For example, the network device can map the value of the identifier of the first segment to the first end symbol, and send the first end symbol to the UE, so that the UE determines the value of the identifier corresponding to the first end symbol, that is, the value of the identifier of the first segment, according to the mapping relationship between the end symbol and the value of the identifier according to the first end symbol received in the first MO.

[0191] Alternatively, the identifier of the first segment can be carried according to other implementation manners, which are not limited herein.

[0192] In addition, the end symbol can also be carried in the time domain offset, so that the UE parses the end symbol according to the time domain offset of the first segment. For example, the UE can determine the time domain offset according to the time length between the time when the first segment is received and the starting time of the first MO, and then determine the end symbol according to the mapping relationship between the time domain offset and the end symbol. For example, if the time domain offset is represented by the number of time slots, the end symbol can be mapped with the time domain offset of 4 time slots, so that when the UE determines that the time domain offset of the first segment is 4 time slots, it determines that the first segment currently received is the last segment sent by the network device in the listening period, so that the UE can determine the segment in which the UE does not listen to the wake-up signal in the second MO.

[0193] In the embodiment described in the above FIG. 12, the UE can determine whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the end symbol, and the end symbol is sent by the network device to the UE separately. In other embodiments, the UE can determine whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the target number, wherein the target number is the number of segments of the wake-up signal to be sent by the network device in the listening period.

[0194] In the following, the application is exemplarily described by taking the application to the communication system shown in FIG. 1 as an example.

[0195] Referring to FIG. 14, a communication method provided by an embodiment of the present application is shown. As shown in FIG. 14, the flow of the communication method includes the following steps:

[0196] S1401: The network device generates a first segment of a wake-up signal.

[0197] In the embodiment, the specific implementation of step S1401 can be described with reference to the related description of step S401 in the embodiment of FIG. 4 described above, and will not be described here for brevity.

[0198] S1402: The network device sends a first segment of the wake-up signal to the UE in a first MO, where the first MO is one of a plurality of MOs included in a listening period, and the plurality of MOs further includes a second MO, which is located after the first MO in the time domain.

[0199] In this embodiment, the specific implementation of step S1402 can be described with reference to the related description of step S402 in the embodiment of FIG. 4. For brevity, the description is omitted here.

[0200] S1403: The UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to a target number, where the target number is carried in the first segment, and the target number is the total number (quantity) of segments of the wake-up signal to be sent by the network device in the listening period.

[0201] S1404: In a case where the number of segments of the wake-up signal received by the UE in the listening period reaches the target number, the UE does not listen to the segments of the wake-up signal in the second MO.

[0202] The UE can determine whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the first segment, where the first segment can include a target number, and the target number is the number of segments of the wake-up signal to be sent by the network device in the listening period. Furthermore, in a case where the number of segments of the wake-up signal received by the UE in the listening period reaches the target number, and the first segment is the last segment sent by the network device in the listening period, the UE does not need to continue to receive the segments of the wake-up signal in the subsequent MO of the listening period, thereby reducing the capability consumption of the UE.

[0203] For example, referring to FIG. 5. Since the network device does not need to send the segment if the UE in the set corresponding to each bit carried by the segment does not perform the target operation, the network device does not need to send segment 1 and segment 4, and the number of segments of the wake-up signal to be sent by the network device in the listening period is 2, that is, the target number is 2. Furthermore, if the UE in the set corresponding to bit 14 receives segment 3, and the number of segments of the wake-up signal received by the UE in the listening period reaches the target number 2, the UE in the set can determine that segment 3 is the last segment sent by the network device in the listening period. Furthermore, the UE in the set can determine that segment 4 will not be sent by the network device, that is, the UE in the set corresponding to each bit carried by segment 4 does not perform the target operation, and therefore, the UE in the set does not need to continue to receive the segments of the wake-up signal in the subsequent MO.

[0204] It should be noted that the target quantity can be carried in a first superposition sequence of the first segment, where the first superposition sequence can be a specific superposition sequence of multiple superposition sequences corresponding to the segment of the wake-up signal.

[0205] Alternatively, the target quantity can be carried in a first preamble sequence of the first segment, where the first preamble sequence can be a specific preamble sequence of multiple preamble sequences corresponding to the segment of the wake-up signal.

[0206] Alternatively, the target quantity can be carried in first scrambling information of the first segment, where the first scrambling information can be a specific scrambling information of multiple scrambling information corresponding to the segment of the wake-up signal.

[0207] Alternatively, the target quantity can be carried in a target field in the first segment (the segment of the wake-up signal defined in the R18 communication standard or other existing communication standards).

[0208] In addition, the target quantity can also be carried in the first segment according to other implementation manners, which is not limited.

[0209] In this embodiment, for other implementation manners of steps S1403 and S1404, please refer to the description of the related part of steps S403 and S404 in the embodiment shown in FIG. 4, which will not be repeated here for brevity.

[0210] In addition, the UE can determine whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the identification of the first segment and the target quantity, and the identification of the first segment and the target quantity are carried based on different carrying manners. The following is an exemplary description.

[0211] The identification of the first segment can be carried in a superposition sequence corresponding to the first segment, a preamble sequence of the first segment, scrambling information corresponding to the first segment, or a target field in the first segment (the segment of the wake-up signal defined in the R18 communication standard or other existing communication standards).

[0212] Alternatively, the identification of the first segment can be carried in a time domain offset.

[0213] Alternatively, the identification of the first segment can be carried according to other implementation manners, which is not limited.

[0214] In addition, the target number can also be carried in the time domain offset, so that the UE determines the target number according to the time domain offset of the first segment. For example, the UE can determine the time domain offset according to the time length between the time when the first segment is received and the starting time of the first MO, and then according to the mapping relationship between the time domain offset and the target number, the UE can determine the target number. For example, if the time domain offset is represented by the number of slots, the target number 1 can be mapped to the time domain offset of 1 slot, the target number 2 can be mapped to the time domain offset of 2 slots, and so on. Thus, when the UE determines that the time domain offset is 1 slot, it determines that the number of segments of the wake-up signal sent by the network device in the current monitoring period is 1, and when the UE determines that the time domain offset is 2 slots, it determines that the number of segments of the wake-up signal sent by the network device in the current monitoring period is 2.

[0215] In the embodiment described in FIG. 14, the UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the target number. In other embodiments, the UE can determine whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to a signal sent by the network device alone, for example, a low-power synchronization signal (LPSS), and the target number is carried in the LPSS.

[0216] The following will be described in conjunction with FIG. 15, taking the application to the communication system shown in FIG. 1 as an example.

[0217] Referring to FIG. 15, a communication method provided by an embodiment of the present application is shown. As shown in FIG. 15, the flow of the communication method includes the following steps:

[0218] S1501: The network device sends an LPSS to the UE, wherein the target number is carried in the LPSS, and the target number is the total number of segments of the wake-up signal to be sent by the network device in the monitoring period.

[0219] The network device can send information related to the first segment to the UE, where the information related to the first segment can be the LPSS, and the target quantity carried in the LPSS is the number of segments of the wake-up signal to be sent by the network device in the listening period. Moreover, the target quantity can be used to indicate whether there is a segment of the wake-up signal corresponding to the UE in the second MO. Based on this, after receiving the LPSS, the UE can parse the LPSS to obtain the target quantity, and in the case that the number of segments of the wake-up signal received by the UE in the listening period reaches the target quantity, at this time the first segment is the last segment sent by the network device in the listening period, the UE does not need to continue to receive the segment of the wake-up signal in the subsequent MO of the listening period, thereby reducing the capability consumption of the UE.

[0220] In this embodiment, the following implementation examples of carrying the target quantity in the LPSS are provided.

[0221] In the first implementation example, the network device can send a sequence of different kinds of LPSS to the UE, and the sequence of different kinds of LPSS can be used to carry information, that is, the target quantity can be carried in the first sequence of LPSS in the sequence of multiple LPSS sent by the network device to the UE. For example, the network device can map the value of the target quantity to the first sequence of LPSS, and send the first sequence of LPSS to the UE, so that the UE determines the value of the target quantity according to the first sequence of LPSS and the mapping relationship between the sequence of LPSS and the value of the target quantity.

[0222] In the second implementation example, the network device can send a sequence of shifted LPSS obtained by cyclically shifting the sequence of LPSS by different numbers of moving bits to the wake-up signal, and the sequence of LPSS with different numbers of moving bits can be used to carry information, that is, the target quantity can be carried in the first sequence of LPSS obtained by cyclically shifting the sequence of LPSS by the first number of moving bits and sent by the network device to the UE. For example, the network device can map the value of the target quantity to the first number of moving bits, and send the first sequence of LPSS obtained by cyclically shifting the sequence of LPSS by the first number of moving bits to the UE, so that the UE determines the first number of moving bits according to the first sequence of LPSS, and further determines the value of the target quantity.

[0223] In addition, the target quantity can also be carried in the LPSS by other implementation manners, which are not limited.

[0224] S1502: The UE determines the target quantity according to the received LPSS.

[0225] S1503: The network device generates the first segment of the wake-up signal.

[0226] In the embodiment, the specific implementation of step S1503 can be described with reference to the related description of step S401 in the embodiment of FIG. 4, and details are not described herein for brevity.

[0227] S1504: The network device sends, to the UE, a first segment of the wake-up signal in a first MO, where the first MO is one of a plurality of MOs included in a listening period, and the plurality of MOs further include a second MO, which is located after the first MO in the time domain.

[0228] In the embodiment, the specific implementation of step S1504 can be described with reference to the related description of step S402 in the embodiment of FIG. 4, and details are not described herein for brevity.

[0229] S1505: In a case where the number of segments of the wake-up signal that have been received within the listening period reaches a target number, the UE does not listen to the segments of the wake-up signal in the second MO.

[0230] In the embodiment, other implementations of step S1504 and step S1505 can be described with reference to the related description of step S1403 and step S1404 in the embodiment of FIG. 14, and details are not described herein for brevity.

[0231] In the embodiment of FIG. 15, it is assumed that the UE determines, according to the LPS, whether there is a segment corresponding to the UE in the second MO of the wake-up signal, and the target number is carried in the LPS. In other embodiments, the network device can jointly encode the identifier of the first segment and the target number, and the UE can determine, according to a result of the joint encoding, whether there is a segment corresponding to the UE in the second MO of the wake-up signal, and the joint encoding of the identifier of the first segment and the target number is carried in the first segment.

[0232] The following describes an example of application to the communication system of FIG. 1 with reference to FIG. 16.

[0233] Referring to FIG. 16, a communication method provided in an embodiment of the present application is shown. As shown in FIG. 16, the flow of the communication method includes the following steps:

[0234] S1601: The network device generates a first segment of a wake-up signal.

[0235] In the embodiment, the specific implementation of step S1601 can be described with reference to the related description of step S401 in the embodiment of FIG. 4, and details are not described herein for brevity.

[0236] S1602: The network device sends a first segment of the wake-up signal to the UE in a first MO, where the first MO is one of a plurality of MOs included in a listening period, and the plurality of MOs further includes a second MO, which is located after the first MO in the time domain.

[0237] In this embodiment, the specific implementation of step S1602 can be described with reference to the related description of step S402 in the embodiment of FIG. 4. For brevity, the description is not repeated here.

[0238] S1603: The UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the identification of the first segment and the result of the joint encoding of the target number.

[0239] S1604: In the case where the result of the joint encoding indicates that there is no segment of the wake-up signal corresponding to the UE in the second MO, the UE does not listen to the segment of the wake-up signal in the second MO.

[0240] The UE can determine the result of the joint encoding of the identification of the first segment and the target number according to the first segment, and then obtain the identification of the first segment and the target number by parsing. The UE determines whether there is a segment corresponding to the UE in the second MO of the wake-up signal according to the identification of the first segment and the target number. The target number is the number of segments of the wake-up signal to be sent by the network device in the listening period.

[0241] In this way, the number of MOs used by the UE when listening to the signal is reduced, thereby reducing the energy consumption of the UE in the second MO and subsequent MOs, and achieving energy saving.

[0242] Specifically, the network device can jointly encode the identification of the first segment and the target number, that is, the network device uniquely maps all possible value conditions of the identification of the first segment and the target number to one value of the result of the joint encoding, and sends the result of the joint encoding to the UE, so that the UE determines the values of the target number and the identification of the first segment according to the value of the result of the joint encoding, and uses the mapping relationship between the result of the joint encoding and the target number and the identification of the first segment.

[0243] For example, for the four wake-up signal segments shown in FIG. 5, the ten possible combinations of the first segment identifier and the target number include "1 and 1", "1 and 2", "2 and 2", "1 and 3", "2 and 3", "3 and 3", "1 and 4", "2 and 4", "3 and 4", and "4 and 4". Thus, the combination of the first segment identifier and the target number can be mapped to the first value of the ten possible values of the jointly encoded result, and then the UE can determine the value of the target number and the first segment identifier according to the first value and the mapping relationship between the jointly encoded result and the target number and the first segment identifier. For example, the combination of the first segment identifier and the target number "1 and 1" can be mapped to the value "1" of the jointly encoded result, and the combination of the first segment identifier and the target number "1 and 2" can be mapped to the value "2" of the jointly encoded result.

[0244] In addition, the network device can use other ways to jointly encode the first segment identifier and the target number, which is not limited.

[0245] For example, the jointly encoded result of the first segment identifier and the target number can be carried in the superposition sequence corresponding to the first segment, the preamble sequence of the first segment, the scrambling information corresponding to the first segment, or the target field in the first segment (segment of the wake-up signal defined in the R18 communication standard or other existing communication standards).

[0246] Alternatively, the jointly encoded result can be carried in the time domain offset.

[0247] Alternatively, the jointly encoded result can be carried in the information indication signal.

[0248] Alternatively, the jointly encoded result can be carried according to other implementation manners, which is not limited.

[0249] It should be noted that the execution order of the plurality of steps in the method embodiments shown in FIGS. 4, 9, 11, 12, 14, 15, and 16 is only an example, and is not used to limit the execution order of the plurality of steps in other embodiments. The execution order of the plurality of steps can also be in other order, which is not limited.
