[0034] The technical solutions of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0035] It should be noted that in this disclosure, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0036] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0037] In the description of this disclosure, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "more than one" means two or more.

[0038] In wireless communication systems, UEs need to listen to the physical downlink control channel (PDCCH) to receive critical control information from the network, such as downlink and uplink resource allocation and power control commands.

[0039] Currently, in order to effectively manage power consumption and ensure timely response to network commands, UEs need to determine when to listen to the PDCCH and when to start the relevant timers according to specific rules.

[0040] For example, the UE can trigger the PDCCH listening or timer start based on a pre-configured DRX cycle.

[0041] However, as the power management requirements of the UE change, the DRX cycle pre-configured in the UE is difficult to synchronize with the changes in power management requirements, which reduces the power management efficiency of the UE.

[0042] Therefore, how to improve power management efficiency has become a technical problem that urgently needs to be solved.

[0043] To address the aforementioned technical problems, this disclosure provides a communication method applicable to low-power wake-up scenarios. In low-power wake-up scenarios, instead of listening to low-power wake-up signals at each designated monitoring point as the trigger for the physical downlink control channel (PHC) or starting a timer, the method utilizes this information. This allows the network side to flexibly distribute low-power wake-up signals at one or more designated monitoring points to manage terminal wake-up without reconfiguring the PHC monitoring timings. This synchronizes changes in terminal power management requirements, improves power management efficiency, and enhances terminal energy efficiency.

[0044] In this embodiment of the invention, the network architecture of the mobile communication network (including but not limited to second-generation mobile communication technology (2G), third-generation mobile communication technology (3G), fourth-generation mobile communication technology (4G), fifth-generation mobile communication technology (5G), and future mobile communication networks (such as the evolution of the fifth-generation mobile communication technology (5G-A), sixth-generation mobile communication technology (6G)), and seventh-generation mobile communication technology (7G)) may include at least a first communication node and a second communication node, which may be referred to as the first node and the second node, respectively.

[0045] For example, as shown in FIG1, an architecture diagram of a communication system provided in an embodiment of the present disclosure is provided. The communication system may include: a first node 101 and a second node 102.

[0046] The second node 102 can configure one or more time-frequency domain positions for the first node 101 as monitoring occasions (MOs) to instruct the first node 101 to listen for low power wake-up signals (LP-WUS) sent by the second node 102 on these one or more MOs, thereby managing the first node 101's PDCCH listening or timer startup on these one or more MOs.

[0047] Optionally, the first node 101 can independently configure one or more time-frequency domain resources (MOs) and send one or more MOs configured by the first node 101 to the second node 102, so that the second node 102 can manage the first node 101's PDCCH listening or timer startup by sending LP-WUS on these one or more MOs.

[0048] In this embodiment of the disclosure, the first node 101 can listen to the LP-WUS sent by the second node 102 on one or more MOs configured by the second node 102. If the first node 101 listens to the LP-WUS sent by the second node 102 on a certain MO, the first node 101 can listen to the PDCCH or start a timer on that MO based on the LP-WUS being listened to.

[0049] Similarly, if the first node 101 does not listen to the LP-WUS sent by the second node 102 on a certain MO, the first node 101 may not listen to the PDCCH or start the timer on that MO.

[0050] In this way, without reconfiguring the monitoring timing, the second node 102 can manage the wake-up of the terminal side by flexibly issuing LP-WUS in one or more specified MOs to synchronize the changes in the power management requirements of the first node 101 and improve power management efficiency.

[0051] It should be noted that the first node 101 can be a user equipment node, such as a passive IoT device, tag, or terminal. The second node 102 can be a network equipment node, such as a base station, auxiliary node, or intermediate node.

[0052] In this context, a base station (BS) can be a base station in LTE, Long Term Evolution Advanced (LTEA) or an evolved Node B (eNB or eNodeB), a base station device (gNB) in a 5G network, or a base station in a future communication system. Base stations can include various macro base stations, micro base stations, femtocell base stations, wireless remote extensions, reconfigurable intelligent surfaces (RISS), routers, relay stations, transmission and reception points (TRPs), receivers, access points (APs), wireless fidelity (Wi-Fi) devices, and other network-side equipment. A base station can sometimes also be referred to as a reader or reader used for communication with terminals.

[0053] A terminal can be a device with wireless transceiver capabilities. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminals, augmented reality (AR) terminals, wireless terminals in industrial control, wireless terminals in self-driving vehicles, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, and so on. The embodiments of this disclosure do not limit the application scenarios. A terminal may also be referred to as a user, user equipment (UE), A-IoT device, access terminal, UE unit, UE station, mobile station, mobile station, remote station, transmitter, remote terminal, mobile device, UE terminal, wireless communication device, UE agent, or UE device, etc., and the embodiments of this disclosure do not limit this to these terms.

[0054] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices included in Figure 1 and the names of each device are not limited. In addition to the devices shown in Figure 1, the communication system may also include other devices, such as core network devices.

[0055] The application scenarios of the embodiments disclosed herein are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.

[0056] Figure 2 shows a flowchart of a communication method. As shown in Figure 2, the communication method is applied to the first node and includes: S201-S202.

[0057] In S201, a low-power wake-up signal is listened for at least one monitoring opportunity.

[0058] LP-WUS is used to trigger the listening of PDCCH or the start of the timer.

[0059] In other words, the information carried by LP-WUS is used to wake up the receiver to trigger PDCCH listening or timer startup.

[0060] In this embodiment of the disclosure, at least one MO can be a low-power wake-up signal occasion (LP-WUS occasion, LO), which is used to indicate the duration or time window during which LP-WUS may occur (i.e., the second node may send LP-WUS).

[0061] Alternatively, at least one MO can be determined based on the first configuration information.

[0062] In some embodiments, the first configuration information may include at least one of the following 1.1-1.5:

[0063] 1.1. MO quantity;

[0064] 1.2. MO interval;

[0065] 1.3. A duration or time window containing at least one MO;

[0066] 1.4 The offset between the starting MO and the paging frame or reference time point in at least one MO;

[0067] 1.5. Cycle.

[0068] The MO interval is based on milliseconds (ms), slots, subframes, or frames and is used to describe the interval between two MOs.

[0069] The periods shown in 1.5 are the periods of LO, LP-WUS, MO, and a window.

[0070] The MO spacing shown in 1.2 can be determined by the high-level parameters corresponding to the gap, or by the offset of the starting position of the MO and LO, the beam index, or the associated SSB.

[0071] The time window or duration shown in 1.3 can be determined based on a period of time, or it can be determined based on at least one of the number of slots, the number of MOs, and the number of symbols.

[0072] In other words, the first node can determine at least one MO based on at least one of the information shown in 1.1-1.5 above.

[0073] It should be noted that the first timer includes a duration-on timer for the duration of connected discontinuous reception (C-DRX), while the second timer is another timer triggered by LP-WUS, which is different from the duration-on timer.

[0074] In some embodiments, there is an offset between the starting MO and the first timer or the second timer in at least one MO.

[0075] In S202, the monitoring of the physical downlink control channel or the start of the timer is determined based on the low-power wake-up signal.

[0076] Understandably, in low-power wake-up scenarios, listening for low-power wake-up signals at one or more designated monitoring points serves as the listening stimulus for the physical downlink control channel or the start stimulus for the timer, rather than listening or starting the timer at every physical downlink control channel timing point. This allows the network side to manage terminal-side wake-up by flexibly issuing low-power wake-up signals at one or more designated monitoring points without needing to reconfigure the physical downlink control channel monitoring timings. This synchronizes changes in the terminal-side power management requirements and improves power management efficiency.

[0077] In some embodiments, the information carried by LP-WUS may be contained in at least one of the following 2.1-2.4:

[0078] 2.1 On / off keying on, OOK-ON symbol;

[0079] 2.2. On / off keying off (OOK-OFF) symbol;

[0080] 2.3. Sequence;

[0081] 2.4. The sequence on the OOK-ON symbol.

[0082] In other words, the information carried by LP-WUS can be carried on an on-off keying (OOK) symbol, on a sequence, or on an OOK symbol combining a sequence. This expands the information carrying methods of LP-WUS, making it easier for different types of WUR receivers to receive the signal.

[0083] The number of bits of information carried by the sequence can be the same or different on different symbols; and the symbol can include any of the following: orthogonal frequency division multiplexing (OFDM) symbol, on / off keying OOK symbol, OOK-ON symbol.

[0084] In other words, by flexibly changing the number of bits of information carried on different symbols, the information carried by sequences of different lengths can be flexibly distributed across these symbols.

[0085] It should be noted that the information carried by a sequence can include the number of information bits and information indicating subgroups. Generally speaking, the information indicating subgroups requires a certain number of information bits.

[0086] In addition, a sequence can be a scrambled sequence, an overlaid sequence, a ZC sequence, an M sequence, a Gold sequence, or an OFDM sequence.

[0087] Optionally, the sequence can be mapped to 5 or 6 bits of LP-WUS information; or, the sequence can be mapped to 5 or 6 bits of LP-WUS information encoded by Reed-Muller (RM).

[0088] It should be noted that the RM encoding method or process can be determined according to the technical specification (TS) 38.212 in the relevant technology.

[0089] In some embodiments, the above sequence may satisfy at least one of the following 3.1-3.3:

[0090] 3.1 The sequence corresponding to the position or index of the first type of symbol carries information about the first number of bits, and the sequence corresponding to the position or index of the second type of symbol carries information about the second number of bits;

[0091] 3.2. Carry 5 or 6 bits of sequence information on 3 symbols;

[0092] 3.3. Carry 5 or 6 bits of sequence information on 2 symbols.

[0093] In other words, the number of bits of information carried by the sequence corresponding to different types of symbols is also different. That is, the number of bits of information carried by the sequence corresponding to some symbols is the same, while the number of bits of information carried by the sequence corresponding to some symbols is different, and the number of bits of information carried by the sequence jointly carried by different numbers of symbols can also be different.

[0094] In some embodiments, the sequence corresponding to the position or index of the first type of symbol carries information about the first number of bits, and the sequence corresponding to the position or index of the second type of symbol carries information about the second number of bits, and the first number of bits and the second number of bits satisfy at least one of the following:

[0095] The first bit has 4 bits, and the second bit has 1 bit.

[0096] The first bit has 3 bits, and the second bit has 2 bits;

[0097] The first bit has 2 bits, and the second bit has 3 bits;

[0098] The first bit has 2 bits, and the second bit has 1 bit.

[0099] For example, to carry 5 bits of information, the i-th OOK-ON symbol carries 3 bits of information through a sequence, and the (i+1)-th OOK-ON symbol carries 2 bits of information through a sequence. The i-th OOK-ON symbol determines the position of the first type of symbol, and the (i+1)-th OOK-ON symbol determines the position of the second type of symbol.

[0100] For example, to carry 5 bits of information, the i-th and i+1-th OOK-ON symbols carry 2 bits of information through a sequence, and the (i+2)-th OOK-ON symbol carries 1 bit of information through a sequence. The i-th or i+1-th OOK-ON symbol determines the position of the first type of symbol, and the (i+2)-th OOK-ON symbol determines the position of the second type of symbol. The i-th symbol can also be described by an index value; the index of the OOK-ON symbol can be determined by the OFDM symbol index.

[0101] In some embodiments, the information carried by the above sequence may be determined according to at least one of the following 4.1-4.9:

[0102] 4.1 The number of OOK-ON symbols;

[0103] 4.2 The location or index of the OOK-ON symbol;

[0104] 4.3 Number of OFDM symbols;

[0105] 4.4 Location or index of OFDM symbols;

[0106] 4.5 The number of OOK-ON symbols at the position of the OFDM symbol;

[0107] 4.6 Number of Paging Opportunities (POs) associated with the Locator (LO);

[0108] 4.7 The maximum number of subgroups for each PO;

[0109] 4.8. Bit information after RM encoding;

[0110] 4.9 Number of OOK symbols contained in OFDM symbols.

[0111] Among them, for the maximum number of subgroups for each PO shown in 4.7 above, when the maximum number of subgroups for each PO is 31, the sequence can carry 5 or 6 bits of information;

[0112] Alternatively, if the maximum number of subgroups per PO is 15, the sequence can carry 5 or 6 bits of information.

[0113] The length of the bit information after RM encoding as shown in 4.8 above can be 6 or 8.

[0114] The number of POs associated with the LO shown in 4.6 above can be the number of POs included in a paging frame (PF);

[0115] Alternatively, the number of POs associated with an LO can be 1, 2, or 4.

[0116] In some embodiments, the maximum number of subgroups, or the maximum number of subgroups per PO, is determined based on higher-level parameters.

[0117] In some embodiments, a subgroup represents at least one UE, and there may be multiple UEs corresponding to the subgroup.

[0118] In some embodiments, the OOK-ON symbol can be described as a chip or an OOK chip.

[0119] In some embodiments, the LO may be associated with at least one PO.

[0120] In other words, a LO can be associated with one or more POs, and thus a single LO can be used to manage the wake-up of subgroups under one or more POs at once.

[0121] In some embodiments, the number of OOK symbols contained in an OFDM symbol is called the M value of the OOK signal, which can be determined according to higher-layer parameters. The M value is typically at least one of 1, 2, and 4. For example, M = 4 indicates that the number of OOK symbols or the number of OOK chips contained in an OFDM symbol is 4.

[0122] In some embodiments, the state indicated by LP-WUS includes at least one of the following 5.1-5.4:

[0123] 5.1 Indicates the first state of all subgroups under a PO;

[0124] 5.2 Indicates the second state of a subgroup under one or more POs;

[0125] 5.3 Indicates the third state of all subgroups under all POs;

[0126] 5.4 Indicates the fourth state of all subgroups under multiple POs.

[0127] In other words, LP-WUS can manage wake-up of subgroups under one or more POs by indicating different states.

[0128] It should be noted that the state indicated by LP-WUS can also be described as the state contained in LP-WUS. These states are indicated by LP-WUS or correspond to information carried by LP-WUS. Furthermore, the state indicated or contained by LP-WUS represents the states that LP-WUS may include, and does not mean that LP-WUS will indicate multiple states in a single transmission. Generally, one LP-WUS transmission carries or indicates one state, and different LP-WUS transmissions may carry or indicate different states.

[0129] In some embodiments, the state indicated by LP-WUS mainly refers to a value or index of the information carried by LP-WUS, such as the value of at least one binary bit or a decimal value, or the state indicated by LP-WUS may correspond to at least one subgroup. When the UE (i.e., the first node) detects the subgroup corresponding to the state and determines that it belongs to that subgroup, the UE will be woken up to listen to the PDCCH or trigger a timer.

[0130] Where the LO is associated with a PO, the state indicated by LP-WUS can satisfy at least one of the following 6.1-6.4:

[0131] 6.1 The states indicated by LP-WUS include any number of second states in the set {32,16,8,4};

[0132] 6.2 The states indicated by LP-WUS include at least one first state and / or any number of second states in the set {31,15,7,3};

[0133] 6.3 The states indicated by LP-WUS include one third state or any number of second states in the set {31,15,7,3};

[0134] 6.4 The states indicated by LP-WUS on the first MO in at least one MO include one third state and X second states, and the states indicated by LP-WUS on the second MO in at least one MO include one first state and X second states, where X is a positive integer.

[0135] Alternatively, when the LO is associated with multiple POs, the state indicated by LP-WUS can satisfy at least one of the following 7.1-7.3:

[0136] 7.1 The state indicated by LP-WUS on the first MO in at least one MO includes a second state or a fourth state, and the state indicated by LP-WUS on the second MO in at least one MO includes a second state;

[0137] 7.2 The state indicated by LP-WUS on the first MO in at least one MO includes a second state or a fourth state, and the state indicated by LP-WUS on the second MO in at least one MO includes a first state or a second state;

[0138] 7.3 The states indicated by LP-WUS on all MOs in at least one MO include the second state or the fourth state.

[0139] In other words, as the number of POs associated with LO changes, the types and number of states indicated by LP-WUS also change.

[0140] Optionally, when LP-WUS indicates a second state, the number of second states corresponding to different POs in the states indicated by LP-WUS can be the same or different.

[0141] In other words, by setting the same number of second states for different Product Objects (POs) in the states indicated by LP-WUS, the design of state management can be simplified. Conversely, by setting different numbers of second states for different POs in the states indicated by LP-WUS, the remaining states of LP-WUS can be fully utilized for indication.

[0142] In some embodiments, if the first node detects that the LP-WUS contains any of the first, third, and fourth states, the first node may stop monitoring the MO in the LO or not monitor the remaining MO in the LO.

[0143] In other words, the state indicated by LP-WUS can be used to manage the receiver's detection of MO, thereby enabling better management of the receiver's power consumption.

[0144] In some embodiments, during the process of determining the listening or timer start of the physical downlink control channel based on the low-power wake-up signal (i.e., S202), the first node can determine the listening or timer start of the PDCCH based on the second configuration information and LP-WUS, that is, the listening or timer start of the PDCCH is determined based on the second configuration information and LP-WUS.

[0145] The second configuration information may include a list, a set, or a bitmap.

[0146] Alternatively, the second configuration information can be used to configure the identification information of the first node. The first node can determine whether to listen to the PDCCH or start the timer if it detects that LP-WUS contains the identification information configured by the second configuration information.

[0147] It should be noted that the identification information can be an index, a radio network temporary identifier (RNTI), or a binary or decimal value.

[0148] In other words, the second configuration information allows for targeted management of the LP-WUS target. Only receivers configured with the second configuration information or with the same identifier information as the second configuration information can respond to LP-WUS to trigger PDCCH listening or timer startup.

[0149] In some embodiments, the second configuration information may be determined based on the capabilities of the first node, such as the first node's ability to detect the number of codepoints.

[0150] The size of the list in the second configuration information can be determined based on the first node's ability to detect the number of codepoints.

[0151] Alternatively, the size of the set in the second configuration information can be determined based on the first node's ability to detect the number of codepoints;

[0152] The size of the bitmap in the second configuration information can be determined based on the first node's ability to detect the number of codepoints.

[0153] In other words, the second configuration information is configured based on the unique capabilities of each receiver, thus distinguishing receivers with different capabilities and enabling targeted management of the LP-WUS target.

[0154] In some embodiments, the MO in the LO may satisfy at least one of the following 8.1-8.8:

[0155] 8.1. A LO contains MOs associated with SSBs;

[0156] 8.2. An LO contains an MO associated with an SSB beam index or the actual transmitted SSB;

[0157] 8.3 The number of MOs contained in an LO is determined by the number of beam indices, the number of synchronization signal blocks (SSBs) associated with LP-WUS, the number of SSBs actually transmitted, and at least one of the parameters F, which are 1, 2, or 4.

[0158] 8.4 The number of MOs contained in a LO is determined by the product of the actual number of SSBs transmitted and the parameter F;

[0159] 8.5 The number of MOs contained in a LO is determined by the product of the number of SSB beam indices and parameter F;

[0160] 8.6 At least one MO is continuous in the time domain, including continuity at the time slot level and / or continuity at the symbol level;

[0161] 8.7 At least one MO has a time-domain gap between two adjacent MOs;

[0162] 8.8 At least one MO has a time-domain gap between two adjacent MOs, and the two adjacent MOs are associated with different beam indices.

[0163] In other words, by using LP-WUS as a low-power synchronization signal (LP-SS) for measurement on at least one MO, the dependence on SSB can be reduced and the power gain can be improved (i.e., power consumption is reduced and energy efficiency is improved).

[0164] In some embodiments, the SSB may be based on a primary synchronization signal (PSS), a secondary synchronization signal (SSS), or a physical broadcast channel (PBCH), or it may be based on two synchronization signals, or one synchronization signal and one PBCH. Its form may change in future wireless communication systems, but it will at least include one synchronization signal.

[0165] Wherein, the association of at least one MO with SSB may include at least one of the following 9.1-9.5:

[0166] 9.1 The index of MO is associated with the first index b, 0 ≤ b < B, where B is the number of SSBs;

[0167] 9.2 The index of MO is associated with the first sequence number k, 1≤k≤B, where B is the number of SSBs;

[0168] 9.3 The index of MO is associated with the second index f, 0 ≤ f < F;

[0169] 9.4. The index of MO is associated with the first index b and the second index f, 0≤b<B, 0≤f<F;

[0170] 9.5. The index of MO is associated with the first index k and the second index f, 1≤k≤B, 0≤f<F.

[0171] It should be noted that the number of SSBs can include: the total number of SSBs, the actual number of SSBs transmitted, the number of SSB beam indices, and the actual number of SSB beam indices transmitted. The number of SSBs can be determined based on the position of the synchronization signal block in the burst set (SSB - PositionsInBurst in SIB1) in system information block type 1 (SIB1).

[0172] In addition, at least one MO may also satisfy at least one of the following 10.1-10.4:

[0173] 10.1 At least one index (b*F+f) in a MO corresponds to an MO that is associated with the SSB index b;

[0174] 10.2 At least one MO corresponds to an index (f*B+b) that is associated with an SSB index b;

[0175] 10.3 At least one MO is associated with the (f*B+k)th MO and the kth SSB;

[0176] 10.4 At least one MO is associated with the ((k-1)*F+f+1)th MO and the kth SSB.

[0177] In other words, multiple MOs are associated with multiple SSBs through indexes or locations, so that multiple MOs correspond one-to-one with multiple SSBs.

[0178] It should be noted that the above SSB can be the actual transmitted SSB; or, the index of the above SSB corresponds to the sequence number of the transmitted SSB; or, the index of the above SSB corresponds to the SSB beam index.

[0179] The following describes, with reference to specific embodiments, the LP-WUS subgroup indication via overlaid sequence in idle mode.

[0180] In some embodiments, the first node determines the information or number of information bits of the overlaid sequence on OOK-ON based on the information bit number or the maximum number of packets encoded by RM.

[0181] It should be noted that during LP-WUS transmission, the number of OOK symbols for each OFDM symbol is determined based on the M value.

[0182] The OOK symbol can include both OOK-ON and OOK-OFF. The OOK-ON symbol can carry overlaid sequence / OFDM sequence / ZC sequence. Each OOK-ON carries n bits of information and requires 2... n A sequence. The UE (i.e., the first node) determines the information carried by LP-WUS based on the detected sequence. The OOK-OFF symbol does not carry a sequence.

[0183] The above sequence can directly map information bits, or it can map information bits after they have been encoded using RM codes.

[0184] For example, a sequence can be mapped to the original information bits.

[0185] In some embodiments, the number of overlaid sequences configured for each OOK-ON is 2, 4, 8, or 16, corresponding to 1, 2, 3, or 4 bits of information. The subgroup identifier (ID) has a 5-bit indication, requiring 5, 3, 2, or 2 OOK-ON symbols respectively.

[0186] Assume that each OOK-ON is configured with X overlaid sequences, carrying log2(X) bits of information in each OOK-ON. In this case, the LP-WUS signal has a total of Y OOK-ON symbols. Combining the aforementioned 5 or 6 bits of information, the first OOK-ON can carry the least significant bit (LSB) of log2(X) from the 5 or 6 bits. The information carried is shown in Table 1 below.

[0187] Table 1. Information Carrying Method of OOK-ON Symbol

[0188] For example, if LP-WUS carries 5-bit or 6-bit information.

[0189] When M=1, and the number of overlaid sequences is 16, an OOK-ON carries 4 bits or one of the 16 sequences. If LP-WUS is 5 or 6 bits of information, the first OOK-ON carries the last 4 bits, the second OOK-ON carries the most significant 1 or 2 bits, the third OOK-ON carries the last 4 bits, the fourth OOK-ON carries the most significant 1 or 2 bits, and so on, in a loop.

[0190] Alternatively, an OOK-ON carries 4 bits or one of 16 sequences. In this case, if LP-WUS is 5-bit or 6-bit information, the first OOK-ON carries the last 4 bits, the second OOK-ON carries the most significant bit, the third OOK-ON carries the last 4 bits, the fourth OOK-ON carries the most significant bit, and so on, in a loop.

[0191] For M=1, when the number of overlaid sequences is 8, an OOK-ON carries 3 bits or one of the 8 sequences. If LP-WUS is 5 or 6 bits of information, then the first OOK-ON carries the last 3 bits, the second OOK-ON carries the most significant 2 or 3 bits, the third OOK-ON carries the last 3 bits, the fourth OOK-ON carries the most significant 2 or 3 bits, and so on, in a loop.

[0192] For M=1, when the number of overlaid sequences is 4, each OOK-ON carries 2 bits or one of the 4 sequences. If LP-WUS is 5 or 6 bits of information, then the first OOK-ON carries the last 2 bits, the second OOK-ON carries the third and fourth bits from the end, and the third OOK-ON carries the most significant 1 or 2 bits. The fourth OOK-ON carries the last 2 bits, the fifth OOK-ON carries the third and fourth bits from the end, and the sixth OOK-ON carries the most significant 1 or 2 bits, and so on, in a loop.

[0193] Generally speaking, the above method can be summarized as follows: when the maximum number of bits carried by an OOK-ON is X, or the number of sequences is 2... X LP-WUS contains Y bits of information, and there are two ways to carry this information:

[0194] Method 1: OOK-ON should carry X bits of information as much as possible, with the remaining information carried on individual OOK-ON symbols.

[0195] Divide the Y-bit information into Group, assuming i = 1 to H, where H is the number of OOK-ON symbols in LP-WUS, then the number of bits carried by the i-th OOK symbol is based on... Group confirmed.

[0196] For example, the The first OOK-ON symbol carries X bits, the second Each OOK-ON symbol carries

[0197] When i satisfies Each OOK-ON carries X bits, where n is an integer greater than or equal to 1;

[0198] When i satisfies Each OOK-ON carries what

[0199] For example, as shown in Figure 3, one method of carrying information in symbols is illustrated. For M=4, each OOK-ON symbol carries approximately 2 bits of information, some OOK-ON symbols carry the remaining 1 bit of information, while OOK-OFF symbols carry no information.

[0200] For example, as shown in Figure 4, another method of carrying information in symbols is illustrated. In this method, for M=2, each OOK-ON symbol carries at least 3 bits of information, some OOK-ON symbols carry the remaining 2 bits, while OOK-OFF symbols carry no information.

[0201] For example, as shown in Figure 5, another method of carrying information in symbols is illustrated. In this method, for M=1, each OOK-ON symbol carries approximately 4 bits of information, some OOK-ON symbols carry the remaining 1 bit of information, while OOK-OFF symbols carry no information.

[0202] Method 2: OOK-ON carries m bits of information, with a maximum capacity of X bits, where m ≤ X.

[0203] Divide the Y-bit information into Group, assuming i = 1 to H, where H is the number of OOK-ON symbols in LP-WUS, then the number of bits carried by the i-th OOK symbol is based on... Group confirmed.

[0204] For example, the The first OOK-ON symbol carries m bits, the second Each OOK-ON symbol carries Bit.

[0205] When i satisfies Each OOK-ON carries m bits, where n is an integer greater than or equal to 1.

[0206] When i satisfies Each OOK-ON carries what Bit.

[0207] For example, for M=2, when the number of overlaid sequences is 8 or 4, the information carrying method is similar to that described above. For M=4, when the number of overlaid sequences is 4, the information carrying method is similar to that described above.

[0208] For example, as shown in Figure 6, another method of carrying information in symbols is illustrated. In this method, for M=1 (or 2 or 4), each OOK-ON symbol carries as many m bits of information as possible, some OOK-ON symbols carry the remaining p bits of information, while OOK-OFF symbols do not carry any information.

[0209] It should be noted that in some scenarios, such as when the sequence carries raw bit information, m may not be equal to p. In other scenarios, such as when the sequence carries RM-encoded information, m can be equal to p.

[0210] In some embodiments, the number of bits carried by LP-WUS is determined based on the configured maximum number of subgroups.

[0211] For example, when the configuration supports a maximum of 31 groups, LP-WUS contains 5 bits or 6 bits.

[0212] When the configuration supports a maximum of 15 groups, LP-WUS contains 4 bits or 5 bits.

[0213] When the configuration supports a maximum of 7 groups, LP-WUS contains 3 bits or 4 bits.

[0214] In addition, the number of bits carried by LP-WUS is determined by whether the LO is associated with multiple POs.

[0215] For example, when the number of POs associated with the LO is 4, the number of bits carried by LP-WUS is 5 or 6 bits.

[0216] Generally speaking, the number of bits carried by LP-WUS is determined by at least one of the following: the maximum number of subgroups configured for each PO and the number of POs associated with the LO.

[0217] The following describes, with reference to specific embodiments, the LP-WUS subgroup indication via OOK in idle mode.

[0218] In some embodiments, a base station (i.e., a second node) can be configured to associate / correspond to one or more POs.

[0219] Example 1: When a LO is associated with at least one PO, the status indicated by LP-WUS includes:

[0220] First state: All subgroups under a single PO;

[0221] Second state: a subgroup under one (or more) POs;

[0222] The third state: all subgroups under all POs, such as all POs within a paging period.

[0223] For example, the indication method of LP-WUS may include:

[0224] Method 1: When there is no first state, the LP-WUS indication includes 32, 16, 8, or 4 second states;

[0225] Method 2: When there is a first state, the LP-WUS indication includes 31, 15, 7, and 3 second states;

[0226] Method 3: When there is a third state, the LP-WUS indication includes 1 third state, 31, 15, 7, or 3 second states;

[0227] Method 4: At the first MO position, the LP-WUS indication includes 1 third state and X second states. At the second MO position, the LP-WUS indication includes 1 first state and X second states. X+1 equals a power of 2.

[0228] When LP-WUS specifies a value, a single transmission can only indicate one value, corresponding to a first state, a second state, or a third state. For example, it could be 31, one of 15 second states.

[0229] It should be noted that the third state supported by methods 3 and 4 is beneficial for the network to perform full wake-up and save overhead. Methods 1 or 2 are simpler.

[0230] Example 2: When a LO is associated with at least one PO, Figure 7 shows an association diagram of LO and PO. In this diagram, a paging frame (PF) in a discontinuous transmission cycle (DTX Cycle) can include multiple POs (such as POs #0 to #9), and a LO includes 4 MOs. The first two MOs are associated with the third PO, and the last two MOs are associated with the fourth PO.

[0231] The states indicated by LP-WUS include at least one of the following:

[0232] First state: All subgroups of a PO;

[0233] Second state: A subgroup of (one or more) POs;

[0234] Fourth state: Subgroups owned by multiple POs.

[0235] For example, the indication method of LP-WUS may include:

[0236] Method 1: In the first MO position, LP-WUS includes (UE detection) the second or fourth state. In the second MO position, LP-WUS includes the second state.

[0237] Method 2: At the first MO position, LP-WUS contains a second or fourth state; at the second MO position, LP-WUS contains a first or second state.

[0238] For example, the LP-WUS of the first MO in a LO contains a fourth state or a second state, while the LP-WUS of other MOs in a LO contains a second state.

[0239] For example, the LP-WUS of the first MO in a LO contains a fourth state or a second state, while the LP-WUS of other MOs in a LO contains a second state or a first state.

[0240] The position of the first MO is determined based on the LO period, offset, and the position of the MO within the LO. The position of the MO within the LO can be determined by a parameter, for example, this parameter indicates that the nth MO in the LO is the first MO.

[0241] Alternatively, the position of the first MO can be determined based on the second period or the second offset, where the first period is the period of the LO and the first offset is the offset of the LO.

[0242] Method 3: At all MO positions of the LO, LP-WUS includes a second or fourth state.

[0243] Methods 1, 2, and 3 mentioned above are mainly used to determine the location of wake-up for all subgroups, i.e., the detection of the fourth state.

[0244] In some embodiments, in an LPWUS, when indicating a subgroup, the method of indication (i.e., indicating a second state) includes:

[0245] Method 1: Among the multiple POs associated with LP-WUS, the number of second states under different POs is the same. Each PO has m second states and n POs, satisfying m*n<=31 or 32, where m and n are integers. m is determined according to configuration parameters or according to the number of groups for each PO.

[0246] For example, m second states are one subgroup indications for the first PO;

[0247] Alternatively, when there are m second states, the one subgroup indication is used for the second PO;

[0248] This process continues until there are n POs. n can be 2, 4, or 8.

[0249] Method 2: Among the multiple associated POs, the number of second states varies depending on the PO. Assume the number of second states corresponding to the i-th PO is m. i .at this time Or 2s-1, where s is a positive integer such as 5, 4, 3, 2.

[0250] For example, if a LO is associated with two POs, the states indicated by LP-WUS include:

[0251] One indication of all subgroups, i.e., a fourth state;

[0252] The second state of the 15 first POs;

[0253] The second state of 16 second POs.

[0254] Based on the above methods of indicating "all subgroup" and "one subgroup," the following example illustrates this:

[0255] Example 1: When there are multiple associated POs, the LP-WUS monitored on an MO includes the following states: the number of second states under each PO is the same (single wake-up of a PO), one state indicates the fourth state (full wake-up), and the remaining states indicate the third state (per PO wake-up).

[0256] When a LO is associated with multiple POs, the states corresponding to all subgroup wake-ups of these multiple POs are fixed as all 1s or all 0s. The number of groups indicated under each PO is fixed, and the remaining states are used to configure all subgroup wake-ups at the per PO level.

[0257] For example, the status indicated by LP-WUS includes:

[0258] (1) A status is used to indicate the wake-up of all subgroups of all POs;

[0259] (2) The number of groups configured for each PO is M, and the number of POs is N, where N<=4 and M*N<=32;

[0260] For example, 1 bit indicates the PO index, and 4 bits indicate the subgroup ID. Optionally, the subgroup ID ranges from 0 to 6, with a total of 30 states.

[0261] Alternatively, 2 bits indicate the PO index and 3 bits indicate the subgroup ID. Optionally, the subgroup ID ranges from 0 to 6, with a total of 28 states.

[0262] Alternatively, a LO can be associated with a PO, with 5 bits indicating the subgroup ID. Optionally, the subgroup ID ranges from 0 to 30, for a total of 31 states.

[0263] (3) Use the remaining state to indicate the wake-up of all subgroups per PO when one LO is associated with multiple POs.

[0264] For example, 1 bit indicates the PO index, and 4 bits indicate the subgroup ID. The subgroup ID can optionally range from 0 to 6.

[0265] Alternatively, assuming 5 bits of information and 32 states, two states are used for the purpose of one state indicating the wake-up of all subgroups of all POs, and the other state indicating the wake-up of all subgroups under a specific PO.

[0266] Example 2: When there are multiple associated Product Objects (POs), the first Mobile Object (MO) listens for full wake-up and single-group wake-up, while the second MO listens for wake-up and single-group wake-up per PO.

[0267] (1) In the first MO, a state is used to indicate full wake-up.

[0268] For example, 31, 15, or 7 states are used for a single wake-up when multiple POs have the same subgroup index;

[0269] For example, 15 or 7 states are used to indicate a single-group wake-up of a subgroup index under a PO.

[0270] (2) In the second MO, use 1, 2 or 4 status indicators per PO to wake up.

[0271] For example, 15 or 7 states are used to indicate a single wake-up of a subgroup index under a PO;

[0272] For example, one state is used for per PO wake-up, while 31, 15, or 7 states are used for single-group wake-up of multiple POs with the same subgroup index.

[0273] Example 3: Assuming the number of POs is 2, then the states included in LP-WUS are:

[0274] (1) A status is used to indicate all subgroups under all POs;

[0275] (2) Two states are used to indicate all subgroups under the first PO or the second PO;

[0276] (3) 29 states are used to indicate a single subgroup under a single PO, of which N states are used to indicate a subgroup under the first PO and 29-N states are used to indicate a subgroup under the second PO.

[0277] Alternatively, assuming the number of POs is 4, the included states are:

[0278] (1) A status is used to indicate all subgroups under all POs;

[0279] (2) Four states are used to indicate all subgroups under the first PO or the second PO;

[0280] (3) 27 states are used to indicate a single subgroup under a single PO, of which N states are used to indicate a subgroup under the first PO and 27-N states are used to indicate a subgroup under the second PO.

[0281] Based on the examples above, the general approach can be summarized as follows:

[0282] When a LO is associated with X POs, a status indicates all subgroups under all POs;

[0283] Alternatively, X states indicate all subgroups under the xth PO.

[0284] Alternatively, 32-1-N*(X-1) states are used to indicate a single subgroup under a single PO. In the first (X-1) POs, the number of subgroups corresponding to each PO is N, and the number of subgroups corresponding to the last PO is 32-1-N*(X-1).

[0285] The above method belongs to one of the following implementations. The indication state of LP-WUS includes at least one of the following:

[0286] First state: All subgroups of a PO;

[0287] Second state: A subgroup of (one or more) POs;

[0288] Fourth state: Subgroups owned by multiple POs.

[0289] Below is a specific implementation of further grouping the MOs of a LO. The UE determines the MO locations it needs to monitor based on its subgroup ID, UE ID, or PO location. Specifically:

[0290] K LP-WUS MOs for a beam are divided into G groups, where G is equal to the number of POs in a PF. The UE associated with the nth PO detects the MO(s) in the nth group, such as R*M MOs per group; or M MOs per group.

[0291] Specifically, when a UE associated with the nth PO (PO index corresponding to n-1) detects the MO(s) of the nth group, the information carried by its LP-WUS includes the wake-up of all groups under that PO, and an indication of one of the subgroups in the all subgroups under that PO. At this time, the LP-WUS is 5 bits.

[0292] For example, when G>1, some specific implementations are as follows when G=2:

[0293] Method 1: As shown in Figure 8, this illustrates another association diagram between LO and PO. In this case, different MOs are associated with different POs. The shaded areas represent the POs and MOs monitored by UE1, and the blank areas represent the POs and MOs monitored by UE2. The LP-WUS detected by UE1 / UE2 on the MO may contain indications of all subgroups of the PO, or one of the M subgroups.

[0294] At this point, for the network (i.e., the second node), if all UEs (i.e., the first node) need to be woken up, N POs will require N LP-WUS, which will result in a large network overhead.

[0295] Method 2: As shown in Figure 9, another relationship diagram between LO and PO is illustrated. The MO with shaded and blank areas is a common MO that can simultaneously associate with both the shaded and blank POs.

[0296] At this time, LP-WUS can wake up all subgroups of multiple associated POs. The UE only needs to listen at a specific MO location, instead of needing to detect at a location for each PO, which can save network overhead and avoid excessive detection by the UE.

[0297] In some embodiments, LP-WUS carries the monitoring of all groups of wake-up for all POs at the first MO of the LO, or at a MO location configured by the base station.

[0298] For example, the LP-WUS of this MO does not support wake-up of all groups under a PO.

[0299] Alternatively, on the LP-WUS of the MO, a specific group wake-up under a PO can be supported, which contains at least one of the PO index information and subgroup index information.

[0300] Alternatively, LP-WUS on other MOs may carry or support wake-up for all groups under a PO.

[0301] It should be noted that Method 2 is an improvement on Method 1. Its main feature is that a first MO is defined to monitor the full wake-up of multiple POs or all POs (all subgroups). For the UE, it does not detect this full wake-up state on the second MO.

[0302] The following describes LP-WUS's indication via connected mode, using specific embodiments as an example.

[0303] Instruction Method 1: The UE (i.e., the first node) is configured with a set or a list containing up to eight elements, each element corresponding to a value of the LP-WUS instruction.

[0304] For example, for a UE with the first capability, the set contains at most one element, which corresponds to a value of LP-WUS.

[0305] Alternatively, for a UE with a second capability, the set contains a maximum of two elements, each corresponding to a value of LP-WUS.

[0306] Alternatively, for a UE with third-party capabilities, the set contains a maximum of four elements, each corresponding to a value of LP-WUS.

[0307] Alternatively, for a UE with the fourth capability, the set contains up to 8 elements, each corresponding to a value of LP-WUS.

[0308] Indication Method 2: 32-bit bitmap, where 1 bit corresponds to a specific value.

[0309] For example, the first bit corresponds to the value 0, the second bit corresponds to the value 1 indicating whether it is indicated, and the third bit indicates whether the value 3 is indicated.

[0310] For example, if the payload of LP-WUS is 5 bits or the number of information bits it carries, then the value range of LP-WUS or the element is less than or equal to 32. For example, the value range of the element is 0 to 31 or 1 to 32, corresponding to the value range of LP-WUS of 0 to 31.

[0311] Alternatively, if the LP-WUS payload is 6 bits, then the LP-WUS OR element value range is less than or equal to 64. For example, if the element value range is 0 to 63 or 1 to 64, the corresponding LP-WUS value range is 0 to 63.

[0312] Alternatively, the LP-WUS payload may be X-bit, with a range of less than or equal to 2. X .

[0313] The above configuration is more suitable for specific UE settings, and each UE can be configured with its own set of values.

[0314] It should be noted that to save on signaling overhead, the configuration of Radio Resource Control (RRC) signaling needs to be considered. In this case, the value of LP-WUS is best bound to the UE-ID. For example, the LP-WUS indication should include at least one of the following:

[0315] (1) One value corresponds to all UEs being woken up;

[0316] (2) One or more UEs corresponding to a value are woken up.

[0317] The definition of MO will be introduced below with reference to specific embodiments.

[0318] One MO is defined on X symbols, the UE (i.e., the first node) monitors one or more MOs, and one LO contains at least one MO.

[0319] The relationship between MOs is explained below with specific examples:

[0320] Example 1: When there are multiple beams or multiple repetitions, the repetition is based on M slots. There is a gap when switching beam indexes or adding repetitions.

[0321] For example, as shown in Figure 10, the MO corresponding to repetition 1 under beam 1 occupies the complete first slot and half of the second slot out of the two slots.

[0322] Similarly, under beam 1, repetition 2 corresponds to MO occupying the complete first slot and half of the second slot out of the two slots.

[0323] The MO corresponding to repetition 1 under beam 2 occupies the complete first slot and half of the second slot out of the two slots.

[0324] The MO corresponding to repetition 2 under beam 2 occupies the first complete slot and half of the second slot out of the two slots.

[0325] It should be noted that repetition 1 under beam 1 and repetition 1 under beam 2 can be the same or different.

[0326] In this way, the time domain is discrete, which has time domain diversity gain, but may cause resource fragmentation.

[0327] Example 2: When there are multiple beams or multiple repetitions, the repetition is based on X symbols. There is no gap when the beam index is switched or repetition is added.

[0328] For example, as shown in Figure 11, the MO corresponding to repetition 1 under beam 1 occupies the complete first slot and half of the second slot out of the two slots, while the MO corresponding to repetition 2 under beam 1 occupies the remaining part of the previous slot and occupies the other complete slot. That is, the MO corresponding to repetition 1 under beam 1 and the MO corresponding to repetition 2 under beam 1 together occupy three slots.

[0329] Similarly, the MO corresponding to repetition 1 under beam 2 occupies the complete first slot and half of the second slot out of the two slots, while the MO corresponding to repetition 2 under beam 2 occupies the remaining part of the previous slot and the other complete slot. That is, the MO corresponding to repetition 1 under beam 2 and the MO corresponding to repetition 2 under beam 2 together occupy three slots.

[0330] It should be noted that resource continuity at this point can prevent resource fragmentation.

[0331] In some embodiments, beam1 or beam2 is associated with different SSB indexes.

[0332] Example 3: Repeated multiple times based on X symbols, with gaps in the transition between multiple beams.

[0333] For example, referring to Figure 11 above, as shown in Figure 12, the MO corresponding to beam 1 is not continuous with the MO corresponding to beam 2.

[0334] In some embodiments, when there are no repetitions, or when the number of repetitions R = F, the following characteristics exist:

[0335] Feature 1: The number of MOs satisfies the following: One LO contains K MOs, K = B * F, where B is the number of beam indexes, the number of associated SSBs, or the number of associated actual transmitted SSBs, and F takes at least one of 1, 2, or 4, determined by higher-layer parameters, which affect the flexibility of network scheduling.

[0336] Feature 2: The association between LP-WUS and SSB satisfies:

[0337] (1) The MO with index or serial number [b*F+f] corresponds to the SSB with index or serial number b, where f ranges from 0 to F-1 and b ranges from 0 to B-1.

[0338] When b = 0, the beam directions on the F MOs (Metal Oxides) corresponding to m ranges from 0 to F-1 are consistent, and the beam indices are also consistent. When b = 1, f ranges from 0 to F-1, and the corresponding MO is F+f. The MOs from number F to F+F-1 correspond to beam indices with b = 1. The effect achieved in this case is that each beam has consecutive MOs.

[0339] (2) The MO with index or sequence number [f*B+b] corresponds to index or sequence number bSSB. The value of m ranges from 0 to F-1, and the value of b ranges from 0 to B-1.

[0340] When f = 0, b ranges from 0 to B-1, and the MO index also ranges from 0 to B-1. In this case, B consecutive MOs have different beam indices. When m = 1, the MO index is B+b. In this case, B MOs still correspond to B SSBs or B beam indices. The effect achieved here is that the MOs corresponding to each beam are not consecutive, with an interval of B (B-1 MOs in between).

[0341] (3) The (f*B+k)th MO is associated with the kth SSB; the value of k ranges from 1 to B.

[0342] (4) The ((k-1)*F+f+1)th MO is associated with the kth SSB. The value of k ranges from 1 to B.

[0343] (5) When considering repetition, assume the number of repetitions is R, where r represents the r-th repetition, and 0 ≤ r <R。

[0344] It should be noted that if F = R, the calculation method of (1) or (2) above can be used, replacing F with R and f with r.

[0345] Feature 3: The MO position satisfies:

[0346] (1) MO is continuous in the time domain: slot level continuous (preferred), or symbol level continuous.

[0347] For example, K MOs are slot-level consecutive, meaning one MO is defined on M slots, and the K MOs are slot-level consecutive. There may be symbol-level gaps in between.

[0348] For example, as shown in Figure 13, the MO distribution of 28 symbols in two time slots is illustrated. The two MOs are distributed across two consecutive slots, but the symbols have a time gap and are not consecutive. Specifically, one MO is distributed across the last 12 symbols of the first slot, and the other MO is also distributed across the last 12 symbols of the second slot, occupying the same number of subcarriers or physical resource blocks (RBs).

[0349] For example, K MOs are based on symbol continuity. That is, the ending symbols and starting symbols of different MOs are continuous.

[0350] (2) F MOs are continuous in the time domain, and there is a gap between each F MOs.

[0351] For example, taking F as 4, as shown in Figure 14, there is a gap between every 4 MOs, that is, there is a gap between a group of MOs with b=0 (i.e., 4 MOs) and a group of MOs with b=1.

[0352] (3) B MOs are continuous in the time domain, and there is a gap between each B MOs.

[0353] (4) The above gap is the base station configuration or the default value.

[0354] In other embodiments, the MO has the following characteristics:

[0355] Feature 1: The number of MOs satisfies the following: One LO contains K MOs, K = B * F * R, where B is the number of beam indexes, the number of associated SSBs, or the number of associated actual transmitted SSBs, F takes at least one of 1, 2, or 4, determined by higher-layer parameters, which affects the flexibility of network scheduling, and R is the number of repetitions.

[0356] Feature 2: The association with SSB satisfies:

[0357] (1) The [f*B*R+r*B+b]th MO corresponds to the bth SSB. The effect is to switch beams first, then repeat, and then loop.

[0358] (2) The [b*B*R+f*R+r]th MO corresponds to the bth SSB. At this time, repeat first, then loop, then switch beam.

[0359] In some embodiments, the parameters configured as described above may include at least one of the following:

[0360] 1. Number of repetitions

[0361] 2. The number of beams is determined based on the cell-defining SSB (CD-SSB) of the transmission cell.

[0362] 3. Parameter, which is used to determine F

[0363] 4. gap.

[0364] In some embodiments, an MO is defined based on the following:

[0365] Method 1: Number of slots and number of symbols;

[0366] Method 2: The number of slots and bitmap indicators determine the symbol under the corresponding slot;

[0367] Method 3: Number of start and continuation symbols.

[0368] In summary, the Low Power Wake-up Signal (LP-WUS) is used to save power for the UE. In connected mode, LP-WUS can be used to wake up one or more UEs to listen to the PDCCH or trigger a timer. In idle mode, LP-WUS can wake up one or more groups of UEs to listen to the paging PDCCH. Simultaneously, in idle mode, LP-SS can also be used for measurement, thereby reducing reliance on the SSB and improving power efficiency.

[0369] In other words, the main purpose of this disclosure is to achieve power saving through the design of LP-WUS, including the design of connected LP-WUS and idle / inactive LP-WUS.

[0373] It should be noted that the descriptions of MO and LP-WUS in the above embodiments can be referred to, and will not be repeated here.

[0374] The following describes the communication method provided in the above embodiment, taking the interaction between the first node and the second node as an example, as shown in Figure 16, including: S1601-S1603.

[0375] In S1601, the second node sends a low-power wake-up signal to the first node at at least one monitoring opportunity.

[0376] In S1602, the first node listens for a low-power wake-up signal at at least one monitoring opportunity.

[0377] In S1603, the first node determines whether to listen to the physical downlink control channel or start the timer based on the low-power wake-up signal.

For example, each function can be divided into a separate functional module, or two or more functions can be integrated into one functional module. The integrated module can be implemented in hardware or software. It should be noted that the module division in this disclosure embodiment is illustrative and only represents one logical functional division. In actual implementation, there may be other division methods. The following description uses the example of dividing each functional module according to each function.
