[0004] However, in the case of a short wake-up period, frequent awakening of the receiver will increase the energy consumption of the communication device, while in the case of a long wake-up period, some service signals may not be monitored in time. Therefore, how to reduce the energy consumption of the communication device for monitoring service signals to reduce the power consumption during communication services has become an urgent technical problem to be solved.

[0028] Next, the technical solutions in the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present disclosure belong to the scope of protection of the present disclosure.

[0029] It should be noted that in this disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or having more advantages than other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0030] 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 quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0031] In the description of this disclosure, unless otherwise specified, " / " means "or". For example, A / B may represent A or B. The "and / or" herein is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition,

[0032] "At least one" means one or more, and "a plurality" means two or more.

[0033] In recent years, with the development of communication technologies, the scale of communication systems has become increasingly large, the service interactions between communication devices have become increasingly frequent, and the demand for energy consumption management of communication devices has also increased.

[0034] Currently, to meet the demand for energy consumption management of communication devices, the sleep management of the receiver (or receiving module) of the communication device can be performed, and the receiver is periodically awakened to reduce the energy consumption of monitoring service signals.

[0035] For example, physical downlink control channel skipping (PDCCH skipping) in related energy-saving technologies, downlink control information with cyclic redundancy check scrambled by power saving radio network tempory identity (PS-RNTI) (DCP) (standard (format) 2-6), connected-mode discontinuous reception (DRX).

[0036] Among them, in the DRX mechanism, there is I-DRX or enhanced discontinuous reception (eDRX) in the idle state, and C-DRX in the connected state. PDCCH skipping means that the downlink control information (DCI) is used to instruct the UE to skip the PDCCH monitoring for a period of time during the active time of C-DRX, so as to save power consumption. The DCP mainly refers to using a specific DCI to indicate whether C-DRX needs to be woken up. If there is no service, the UE does not need to wake up and monitor at the duration-on position of C-DRX, so as to save energy.

[0037] However, in the case of a short wake-up period, frequent wake-up of the receiver will increase the energy consumption of the communication device. If the wake-up period is long, some service signals may not be monitored in time. Therefore, how to reduce the energy consumption of the communication device for monitoring service signals to reduce the power consumption during communication services has become a technical problem to be solved urgently.

[0038] Based on this, to solve the above technical problems, the embodiments of the present disclosure provide a processing method based on low-power signals. A separate receiver (i.e., a low-power wake-up receiver (LP-WUR)) is set in the communication device to receive low-power signals, and the main receiver (i.e., the receiver for service signals or service channels) is woken up based on the low-power signals for data transmission and data reception (signal monitoring). When the LP-WUR of the communication device does not detect a low-power signal, the main receiver is controlled to be in a deep sleep state. That is to say, the communication device can manage the sleep of the receiver for service signals or service channels by monitoring a new waveform signal (i.e., a low-power signal) different from the current new radio (NR). The monitored new waveform signal is only used to indicate whether to be woken up, so that the new waveform signal is relatively simple and the monitoring energy consumption thereof is also low. In this way, the energy consumption of the communication device for monitoring service signals can be reduced, and the power saving gain (PSG) and latency gain of the communication device can be improved.

[0039] In the embodiments of the present disclosure, the network architecture of a mobile communication network (including but not limited to 3G, 4G, 5G, and future mobile communication networks (such as the evolution of the fifth-generation mobile communication technology (5G-A), the sixth-generation mobile communication technology (6G))) may at least include a first communication node and a second communication node. It should be understood that, in this example, in the downlink, the first communication node may be a terminal-side device (such as including but not limited to a terminal), and the second communication node may be a network-side device (such as including but not limited to a base station). Of course, in the uplink, the first communication node may also be a network-side device, and the second communication node may also be a terminal-side device. In device-to-device communication between two communication nodes, both the first communication node and the second communication node may be a base station or a terminal. The first communication node and the second communication node may be abbreviated as the first node and the second node respectively.

[0040] Exemplarily, taking the first node as a terminal and the second node as a base station as an example, as Figure 1 shown, a communication system provided by an embodiment of the present disclosure includes a base station 101 and a terminal 102. The number of terminals 102 may be one or more, and the quantity is not limited.

[0041] Among them, the terminal 102 may receive a low-power signal different from the service signal sent by the base station 101, enter the wake-up state, and monitor the service signal.

[0042] In some embodiments, the terminal 102 may receive a low-power signal from the base station 101 through the LP-WUR, and the LP-WUR may be used to receive low-power synchronization signals (LP-SS) / low-power wake-up signals (LP-WUS). Among them, the low-power signal may include LP-SS (i.e., the first low-power signal) and LP-WUS (i.e., the second low-power signal).

[0043] It should be noted that the base station (BS) can be a base station in LTE (Long-Term Evolution), LTE-A (Long-Term Evolution Advanced), or an evolved Node B (eNB or eNodeB), a base station device in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, remote radio heads, reconfigurable intelligent surfaces (RISs), routers, relays, transmit receive points (TRPs), wireless fidelity (WIFI) devices, and other network-side devices.

[0044] The terminal can be a device with wireless transceiver functions. The terminal can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, and so on. The embodiments of the present disclosure do not limit the application scenarios. Sometimes, the terminal can also be referred to as a user, a user equipment (UE), an access terminal, a UE unit, a UE station, a mobile station, a mobile device, a remote station, a remote terminal, a mobile device, a UE terminal, a wireless communication device, a UE agent, or a UE device, etc. The embodiments of the present disclosure do not limit this.

[0045] It should be noted that Figure 1 is only an exemplary framework diagram, Figure 1 the number of devices included in it, and the names of each device are not restricted, and in addition to Figure 1 the devices shown, the communication system may also include other devices, such as core network devices.

[0046] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are for more clearly explaining the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those of ordinary skill in the art can know that with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0047] Figure 2 A flowchart showing a method for processing a low-power signal is shown, as Figure 2 shown. The method for processing a low-power signal is applied to a first node (hereinafter, UE is used as an example for illustration), and includes: S201 - S203.

[0048] S201. Determine the relevant parameters of the low-power signal.

[0049] As a possible implementation manner, the UE can determine the relevant parameters of the low-power signal through at least one of the following four methods (Method 1 to Method 4):

[0050] Method 1: Determine the relevant parameters of the low-power signal according to a predefined method;

[0051] Method 2: Determine the relevant parameters of the low-power signal according to high-layer signaling configuration, system information block (SIB), and radio resource control (RRC) signaling;

[0052] Method 3: Determine the relevant parameters of the low-power signal according to DCI or a media access control control element (MAC CE);

[0053] Method 4: Determine the relevant parameters of the low-power signal according to RRC signaling and DCI.

[0054] Optionally, the relevant parameters of the determined low-power signal may include at least one of the following: activation or deactivation indication; wake-up or non-wake-up indication; resources or locations of the physical uplink control channel (PUCCH); function indication (used to determine whether it is for activation / deactivation indication or to determine the configuration parameters indicating the low-power signal); monitoring period, offset, monitoring duration, number of repetitions, transmission configuration indicator state (TCI state), quasi co-location (QCL) information, frequency hopping indication, time-domain resources of the monitoring occasion, and frequency-domain resources of the monitoring occasion.

[0055] Optionally, when determining the relevant parameters of the low-power signal according to DCI, at least one of the fields of the frequency domain resource allocation (FDRA) field, time domain resource allocation (TDRA) field, modulation and coding scheme (MCS) field, hybrid automatic repeat request (HARQ) field, redundancy version (RV) field, physical antenna port(s) field, demodulation reference signal (DMRS) sequence initialization field, and new data indicator (NDI) does not exist or is used to indicate the relevant parameters of the low-power signal.

[0056] It should be noted that after configuring LP-WUS and activating the monitoring of LP-WUS, as time goes by, it is possible that its configuration for LP-WUS is no longer used. For example, the number of resources can no longer match the channel, resulting in transmission failure or resource waste. Embodiments of the present disclosure can adapt to channel conditions by dynamically changing the configuration of LP-WUS.

[0057] The following introduces, with specific examples, how the UE dynamically determines the relevant parameters of the low-power signal according to DCI.

[0058] 1. Indicate LP-WUS in the group DCI.

[0059] The Group DCI includes DCI formats of the 2-X series, or its search space type is the common search space (CSS) (or common), or it is scrambled with a specific radio network temporary identity (RNTI1), such as INT-RNTI, SFI-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, TPC-SRS-RNTI, CI-RNTI, or cellDTRX-RNTI and, for the C-RNTI, MCS-C-RNTI, CS-RNTI(s), or PS-RNTI that are only applicable to the primary cell, or a new RNTI. It is a type 3-based common search space (CSS).

[0060] After the RRC configures LP-WUS, the UE starts to monitor LP-WUS only when it detects the activation signaling of the DCI. The activated DCI format is DCI format 2-6 or group-specific DCI. For example, when specific LP-WUS higher-layer parameters are configured, DCI format 2-6 or group-specific DCI is used to activate the monitoring of LP-WUS or deactivate the monitoring of LP-WUS.

[0061] The structure of its DCI is: block number 1, block number 2,..., block number N.

[0062] The content included in its DCI or block is:

[0063] (1) Activation / deactivation, or wake up or not wake up

[0064] Among them, 1 bit is used for the activation / deactivation, or wake up or not wake up of the primary cell (PCell) and the primary secondary cell (PSCell). X bits are for the activation / deactivation, or wake up or not wake up of the SCell. M bits are for all serving cells or serving cell groups.

[0065] (2) The 1 bit is used to indicate a function, such as for activation / deactivation, or for modifying or indicating the parameters of LP-WUS. It is used to indicate whether it is for all serving cells, or to indicate for specific SCell group(s).

[0066] (3) Modifying or indicating the parameters of LP-WUS includes at least one of the following: LP-WUS, LP-WUS occasion (LO) monitoring period, offset, LP-WUS monitoring duration, number of repetitions, TCI state information, QCL information, hopping indication, time-domain resources of the monitoring occasion, frequency-domain resources of the monitoring occasion, PUCCH resources or configurations.

[0067] Optionally, after receiving the activation DCI of LP-WUS, if successfully received, an acknowledgment (ACK) is fed back, and the UE starts to monitor LP-WUS. If the reception fails, a NACK is fed back and the UE does not activate the monitoring of LP-WUS.

[0068] 2. Indicate LP-WUS in the scheduling DCI.

[0069] The scheduling DCI includes DCI format of 0-X, 1-X series, or its search space type is USS, or is scrambled with a specific RNTI, such as C-RNTI, MCS-C-RNTI, SP-CSI-RNTI, CS-RNTI(s), SL-RNTI, SL-CS-RNTI, SLSemi-Persistent Scheduling V-RNTI, or NCR-RNTI.

[0070] Activation / deactivation is performed in the uplink DCI, for example, activation or deactivation is performed in the 0-X series DCI format, or for modifying or indicating the parameters of LP-WUS, or indicating the parameters of LP-WUS. When activating or deactivating with DCI, this DCI does not perform data scheduling. That is, FDRA, TDRA, MCS, HARQ, RV, antenna port(s), DMRS sequence initialization, and the NDI field do not exist or are multiplexed.

[0071] Deactivation is performed in the uplink DCI or downlink DCI, or for function indication, or for modifying or indicating the parameters of LP-WUS. For example, in DCI format 0-1, 0-3, 1-1, 1-3.

[0072] It should be noted that the relevant parameters of the low-power signal may include the beam information of the low-power signal.

[0073] In some embodiments, the beam information of the low-power signal is determined by the UE based on at least one of the index of the monitoring occasion, the number of beams, the number of repetitions, and the constant C, or the UE determines it according to the association relationship, or the UE determines it according to the high-layer configuration.

[0074] As a possible implementation, during the process in which the UE determines the beam information of the low-power signal based on at least one of the index of the monitoring occasion, the number of beams, the number of repetitions, and the constant C, the UE determines the beam information at least according to imodN or where i is the index of the monitoring occasion, N is the number of beams, and K is determined by the number of repetitions or the constant C.

[0075] Optionally, during the process in which the UE determines the beam information of the low-power signal according to the association relationship, the UE may have an association relationship when the low-power signal and the synchronization signal block (SSB) have the same number of beams.

[0076] Optionally, during the process in which the UE determines the beam information of the low-power signal according to the high-layer configuration, the UE may configure the beam information or the TCI state information according to the RRC, DCI, or MAC CE.

[0077] Among them, the UE configures the beam information or the TCI-state information according to the RRC to satisfy at least one of the following: the RRC signaling is used to configure the monitoring space or the frequency domain space of at least one low-power signal, and each monitoring space or frequency domain space is associated with or indicates the beam information or the TCI state information; use bits or X bits for indication, H is the number of beam information or TCI state in the set or list, and X is determined by the high-layer parameter, including at least one of {1, 2, 3, 4, 5} bit.

[0078] In the embodiments of the present disclosure, the low-power signal may include a first low-power signal and / or a second low-power signal. Among them, the first low-power signal may be LP-SS / PSS / SSS / SSB, and the second low-power signal may be LP-WUS.

[0079] The following combines specific examples to illustrate the UE's determination of the beam information of the low-power signal.

[0080] In some embodiments, the beam direction of the idle / inactive state LP-WUS / LP-SS is determined.

[0081] Optionally, the beam direction of LP-SS can be determined separately. In one LO, or among N*K LP-WUS monitoring occasions (MO), where N is the number of beams.

[0082] Assume the number of any one MO is i, then 0 <= i <= N*K - 1.

[0083] Assume the beam index is m, then m is greater than or equal to 0, less than or equal to N - 1, and is an integer.

[0084] It should be noted that there is an association relationship between m and i above. When LP-WUS has no repetition (i.e., repeated transmission), K = 1, i = m. When LP-WUS has repetition, then K is the number of repetitions.

[0085] If K > 1, m = i mod N, corresponding to beam switching first, and then repetition.

[0086] If K > 1, Corresponding to repetition first, and then beam switching.

[0087] Among them, LP-WUS and LP-SS have the same number of beam am, and are determined by the same parameters, or separate parameters.

[0088] Optionally, for an OFDM receiver, or an OOK receiver, the beam direction of the received signal is also determined according to the number i of MO.

[0089] Optionally, in a window, assume there are N*K MO, where K = R*C, R is the number of repetitions, and C is a coefficient, constant, or used to determine all monitoring occasions within a window.

[0090] When LP-WUS has no repetition, K = C, and at this time, according to m = i mod N, m can be determined, that is, the beam index;

[0091] When LP-WUS has repetition,

[0092] m = i mod N, corresponding to beam switching first, and then repetition.

[0093] Corresponding to repetition first, and then beam switching.

[0094] In some other embodiments, for the determination of the beam direction of connected-state LP-WUS.

[0095] As a possible implementation, determine the beam direction according to RRC signaling.

[0096] For example, for LP-WUS, new RRC parameters (tci-StatesLPWUS-ToAddList) are defined.

[0097] As another example, multiple monitoring spaces and frequency domain spaces for LP-WUS can be configured. Each monitoring space and frequency domain space has an identity (ID), or the monitoring space or frequency domain space is configured with a TCI state. Among them, the configuration of the monitoring space further includes: period, offset, number of symbols per occasion, symbol position, monitoring space ID, associated frequency domain space ID, duration of the period, LP-WUS monitoring type (such as UE specific or group specific). The configuration of the frequency domain space further includes: frequency domain resources, frequency domain space ID, TCI state.

[0098] As another possible implementation, the beam direction is determined according to the DCI indication.

[0099] For example, through bits indicate one of the TCI states, where H is the number of entries of the TCI states, as shown in Table 1.

[0100] Table 1

[0101]

[0102] As another example, it is indicated by X bits, where X is determined according to the configuration of the higher layer parameters. When X = 2, there are 4 TCI states, and the DCI indicates one of them.

[0103] This indication is indicated in the scheduling DCI or the group DCI, and the group DCI is based on type 3 CSS or is for at least one UE.

[0104] Optionally, the beam direction is determined based on the association with other reference signals or the QCL relationship. Such as the channel state information reference signal (CSI-RS), SSB.

[0105] S202. Process the low-power signal based on the relevant parameters of the low-power signal.

[0106] In the embodiments of the present disclosure, the UE can detect, monitor, and receive the low-power signal from the base station based on the relevant parameters of the low-power signal.

[0107] As a possible implementation, the relevant parameters of the low-power signal include at least one of the following.

[0108] Activation or deactivation indication;

[0109] Wake-up or non-wake-up indication;

[0110] Resources or locations of PUCCH;

[0111] Function indication, used to determine whether it is for activation / deactivation indication, or to determine the configuration parameters for indicating the low-power signal;

[0112] Monitoring period, offset, monitoring duration, number of repetitions, TCI state, QCL information, hopping indication, time-domain resources of monitoring occasion, frequency-domain resources of monitoring occasion.

[0113] In some embodiments, the low-power signal includes a first low-power signal or a second low-power signal. The relevant parameters of the first low-power signal include: at least 1 period, a specific sequence, OOK resources, at least one offset, and the number of beams including at least one of {1, 2, 4, 8}; the relevant parameters of the second low-power signal include: the number of load bits not exceeding 16, 24, 32, or 48, OOK resources, at least one offset, and the number of beams including at least one of {1, 2, 4, 8}.

[0114] S203. Process the signal or channel based on the low-power signal.

[0115] In the embodiments of the present disclosure, the UE may process the signal or channel in response to the second low-power signal. Among them, the second low-power signal is used to wake up and trigger the processing of the signal or channel.

[0116] Optionally, the UE may also process the signal or channel based on the first low-power signal. For example, based on the measurement of the first low-power signal, it is determined whether to monitor the second low-power signal.

[0117] Optionally, the UE may also determine whether to perform signal or channel processing according to the processing of the low-power signal. For example, when the UE does not receive the second low-power signal, the UE does not monitor the PDCCH, does not monitor the PO, and does not perform measurement relaxation.

[0118] As a possible implementation, for the UE to process the signal or channel based on the low-power signal, it may include at least one of the following:

[0119] Determine the PDCCH occasion based on the low-power signal;

[0120] Monitor the PDCCH based on the low-power signal;

[0121] Initiate a physical random access channel (PRACH) based on a low-power signal;

[0122] Transmit PUCCH based on a low-power signal;

[0123] Deactivate the monitoring of the low-power signal based on the low-power signal;

[0124] Determine a search space based on a low-power signal;

[0125] Determine a PDCCH candidate based on a low-power signal.

[0126] The following introduces the signal or channel processing by the above UE based on a low-power signal with specific examples.

[0127] When LP-WUS is enabled, the UE has the right to terminate / stop / deactivate the monitoring of LP-WUS, or feedback the reception situation of LP-WUS. Including:

[0128] (1) Transmit or feedback PUCCH.

[0129] According to the PUCCH resources configured in the activation DCI, the UE performs PUCCH feedback or transmission according to this configuration, which is used to determine whether LP-WUS is successfully received and to tell the base station that the UE terminates / stops / deactivates the monitoring of LP-WUS.

[0130] Determine whether LP-WUS is successfully received according to the PUCCH feedback for scheduling PDSCH, which is used to tell the base station that the UE terminates / stops / deactivates the monitoring of LP-WUS. The UE side will not continue to monitor LP-WUS.

[0131] Determine the feedback resources for the feedback that is only negative acknowledgment (NACK-Only).

[0132] (2) Transmit PRACH.

[0133] According to the specifically configured PRACH resources, after transmitting the specified PRACH, it can be used to inform the base station that the UE terminates / stops / deactivates the monitoring of LP-WUS. The UE side will not continue to monitor LP-WUS.

[0134] (3) Determine the PDCCH occasion, perform the monitoring of PDCCH, determine the search space, and determine the PDCCH candidate

[0135] Based on the received low-power signal, for example, based on the measurement of LP-SS or LP-WUS or LP-SS, RSRP, RSRQ, determine whether to monitor the PDCCH of paging, and determine that its search space is Type1A-PDCCH CSS set, Type2-PDCCH CSSset, or Type2A-PDCCH CSS set, type 3CSS.

[0136] Based on the received low-power signal, determine on which PDCCH occasions to monitor and on which PDCCH candidates to detect.

[0137] Based on the received low-power signal, determine the ID of the search space where the PDCCH to be monitored is located.

[0138] Optionally, if monitoring LP-WUS is based on a window, the window may overlap with the PDCCH monitoring occasions of the paging occasion (PO). The corresponding UE behaviors include:

[0139] 1. Monitor LP-WUS during the window. If there is no LP-WUS indication to wake up, do not monitor the PO.

[0140] 2. Monitor LP-WUS during the window. The window is defined on valid occasions. The valid occasion includes the downlink gap (slot) / symbol, excluding the uplink (UL) slots / flexible symbols / slots, and excluding the PDCCH monitoring occasions of the PO.

[0141] 3. At the timing position where the window overlaps with the PDCCH monitoring occasion of the PO, do not need to monitor LP-WUS. Or whether to monitor LP-WUS depends on the UE implementation.

[0142] It should be noted that this related UE behavior occurs at least once within the window. Whether to skip monitoring I-DRX during the window or not to monitor the PDCCH during the I-DRX period, or whether to skip monitoring LP-WUS during the I-DRX duration or to monitor LP-WUS.

[0143] Such as Figure 3As shown, it shows the positional relationship between the paging time window (PTW) and the LP-WUS window in the eDRX cycle relative to the monitoring moment.

[0144] Optionally, the UE satisfies that the reference signal received power (RSRP), reference signal receiving quality (RSRQ), or measurement result or parameter based on the SSB / secondary synchronization signals (SSS) / primary synchronization signals (PSS) is greater than at least one threshold, and the UE satisfies that the RSRP, RSRQ, or measurement result or parameter based on the LP-SS is greater than at least one threshold. At this time, the UE performs measurement relaxation and monitors the LP-WUS or may monitor the LP-WUS.

[0145] The UE satisfies that the RSRP, RSRQ, or measurement result or parameter based on the LP-SS is greater than at least one threshold, and the UE satisfies the condition of measurement relaxation. At this time, the UE performs measurement relaxation and monitors the LP-WUS.

[0146] The UE satisfies that the RSRP, RSRQ, or measurement result or parameter based on the SSB / SSS / PSSS is greater than at least one threshold, and the UE satisfies the condition of measurement relaxation. At this time, the UE performs measurement relaxation and monitors the LP-WUS.

[0147] Similarly, the UE does not satisfy that the RSRP, RSRQ, or parameter based on the SSB / SSS / PSS is greater than at least one threshold, and the UE satisfies that the RSRP, RSRQ, or parameter based on the LP-SS is greater than at least one threshold. At this time, the UE exits measurement relaxation and monitors the PO.

[0148] It can be understood that by setting a separate receiver (i.e., LP-WUR) in the communication device to receive low-power signals, and based on the low-power signals to wake up the main receiver (i.e., the receiver for traffic signals or traffic channels) for data transmission and data reception (signal monitoring), and when the LP-WUR of the communication device does not detect low-power signals, the main receiver is controlled to be in a deep sleep state. That is to say, the communication device can manage the sleep of the receiver for traffic signals or traffic channels by monitoring a new waveform signal different from the current NR (i.e., the low-power signal), and the monitored new waveform signal is only used to indicate whether to be woken up, so that the new waveform signal is relatively simple and the monitoring energy consumption thereof is also relatively low. In this way, the energy consumption of the communication device for traffic signal monitoring can be reduced, and the PSG and delay gain of the communication device can be improved.

[0149] It should be noted that LP-WUS mainly uses group wake-up, and the UE wakes up based on group wake-up to monitor the PO. If the base station wants to wake up all UEs in the cell, the efficiency based on group wake-up is too low and the overhead is large. Therefore, the embodiments of the present disclosure carry cell-specific wake-up information or full wake-up information through LP-SS or LP-WUS, which can save overhead or enable the UE to receive the wake-up message faster.

[0150] In some embodiments, the first low-power signal is used for synchronization or measurement, and the first low-power signal satisfies at least one of the following: at least 1 period is configured, the first low-power signal is based on a specific sequence, based on OOK modulation or OOK resources, at least one offset is configured, and the configured number of beams includes at least one of {1, 2, 4, 8}; the second low-power signal is used for wake-up, triggering the processing of signals or channels, and indicating packet information, and the second low-power signal satisfies at least one of the following: the number of load bits does not exceed 16, 24, 32, or 48, based on OOK modulation or OOK resources, at least one offset is configured, or the configured number of beams includes at least one of {1, 2, 4, 8}.

[0151] Among them, the packet information includes cell specific or common, group specific or UE specific packets, that is, packets for all UEs, at least one group of UEs, at least one UE, or packets for one or more UEs, one group or multiple groups, with each group containing one or more UEs. The indication of the packet information may be embodied as an ID, an index, or a value.

[0152] The number of payload bits is the number of information-carrying bits after removing the cyclic redundancy check (CRC). For example, for the second lowest power consumption signal, the number of payload bits refers to the number of bits after removing the CRC, which does not exceed 16, 24, 32, or 48.

[0153] In some embodiments, OOK modulation refers to binary on-off keying (OOK), also known as binary amplitude shift keying (2ASK), which controls the turning on and off of a sine carrier with a unipolar non-return-to-zero code sequence. For example, the definition of a multi-subcarrier OOK-ON symbol is a symbol with multi-carrier signal transmission, and the definition of a multi-subcarrier OOK-OFF symbol is a symbol without multi-carrier signal transmission.

[0154] The OOK resource is defined based on OOK symbols (including OOK-ON symbols and OOK-OFF symbols), and the time domain length of its OOK symbols is determined by at least one of the CP length, M value, and SCS. The M value is based on the code rate of Manchester coding, or is determined according to the OFDM symbol length or OOK symbol length, or is determined according to the number of OOK symbols.

[0155] Optionally, the low power consumption signal carries full wake-up information, which includes at least one of the following:

[0156] The indication information or wake-up information of all packets;

[0157] The indication information or wake-up information of all packets based on the low power consumption signal;

[0158] The indication information or wake-up information of all packets based on the time domain position or frequency domain position of the low power consumption signal;

[0159] The indication information or wake-up information of all packets based on at least one PO, at least one PF, or at least one cell or area;

[0160] The indication information or wake-up information of all packets based on the maximum number of packets.

[0161] Among them, the indication information of the packet mainly refers to indicating the packet information, such as at least one group ID or a UE ID or ID or RNTI or value. The wake-up information mainly refers to having a common wake-up. Regardless of which group ID the UE is, when receiving the common wake-up, it will wake up, or will monitor the PDCCH, and will perform corresponding signal or channel processing according to the wake-up information of the low power consumption signal.

[0162] As a possible implementation, at least one cycle can be configured for the first low-power signal, which may include: the cycle of signal transmission, the monitoring cycle for detecting the first low-power signal, or the measurement cycle for measurement. Among them, the configuration of the cycle for the first low-power signal can include high-layer configuration, base station configuration, or pre-configuration and predefined.

[0163] It should be noted that the first low-power signal carries full wake-up information based on a specific sequence. The specific sequence is the complementary sequence corresponding to a sequence; or, the specific sequence is one of at least two configured sequences; or, the specific sequence is one of a pair of sequences in a configured multiple pairs of sequences, and the two sequences in a pair of sequences are complementary sequences; the specific sequence is a binary sequence or a sequence based on pseudo-random noise (PN) sequence or ZC sequence (a special pseudo-random sequence) or maximum length (m) sequence or gold sequence (formed by combining two m sequences according to specific rules). Among them, the binary sequence is a sequence containing only two elements. For example, a sequence containing 0, 1 or a sequence containing -1, 1.

[0164] In the embodiments of the present disclosure, the second low-power signal carries full wake-up information, including at least one of the following: the payload of the second low-power signal includes first indication information for indicating full wake-up information; the monitoring position of the second low-power signal is determined at least according to a cycle or an offset; the sequence of the second low-power signal on at least one OOK resource is a sequence with a specific phase or a specific spreading sequence or a sequence based on specific scrambling.

[0165] Optionally, the first indication information indicates all 0s or all 1s or a certain value. Among them, a certain value may be a binary value (such as 1010101001). Or a decimal value (such as 16), or a hexadecimal value (such as FF).

[0166] In the embodiments of the present disclosure, the low-power signal further includes a preamble sequence part, and satisfies at least one of the following: the preamble sequence part is before the second low-power signal; the sequence included in the preamble sequence part is the same as the sequence included in the first low-power signal; the length of the sequence included in the preamble sequence part is the same as or different from the sequence included in the first low-power signal; the preamble sequence part indicates carrying full wake-up information or packet information.

[0167] In some embodiments, when the value of M is the same or the OOK symbol length is the same, the lengths of the sequences included in the preamble sequence part and the first low-power signal are the same, and the value of M is related to the number of OOK symbols in one OFDM symbol. For example, if there are 4 OOK symbols in one OFDM symbol, then M = 4. Or the value of M is related to the OFDM symbol length L1 or the OOK symbol length L2. For example, based on M = L1 / L2 or (L1 - CP length) / L2, or taking the floor or quotient of M = L1 / L2 or (L1 - CP length) / L2.

[0168] In some embodiments, when the full wake-up information is for all terminals in a cell, it can also be referred to as cell specific wake-up information. The following takes the full wake-up information as cell specific wake-up information as an example for illustration.

[0169] The following introduces the use of LP-SS or LP-WUS to carry cell specific wake-up information in combination with specific examples.

[0170] 1. Use LP-SS to carry cell specific wake-up information.

[0171] Among them, based on LP-SS, there are at least 2 cycles. One is the transmission cycle of the signal, one is the monitoring cycle of the WUR, and there is also a measurement cycle. Among them, the transmission cycle of the signal represents the cycle when the signal is sent from the communication node. Based on the reference time point, an offset may also be configured; the monitoring cycle of the LP-WUR represents the time interval of every other cycle when the UE needs to monitor. This LP-SS contains cell specific wake-up information; the measurement cycle means that when the UE measures based on LP-SS, at least one measurement cycle needs to be measured once to facilitate determining the UE in the serving cell; when both the measurement cycle and the WUR monitoring cycle are configured, the smallest value is used as the standard. The configuration methods include: independent configuration, or a coefficient C is configured for the WUR cycle, representing how many transmission cycles to monitor once.

[0172] Optionally, when the WUR monitoring cycle is configured, it means that there is cell specific wake-up information that needs to be detected.

[0173] For example, in a cell, at least one, a pair, or 2 pairs of binary LP-SS sequences are configured.

[0174] Among them, when a cell configures one sequence, its complementary sequence is used for cell specific wake-up (for example, the complementary sequence of 101010 is 010101);

[0175] When a cell configures at least two sequences, one of the sequences is used for cell specific wake-up, or the other is not used for wake-up.

[0176] When a cell configures at least one pair of sequences, one of the pair of sequences is used for cell specific wake-up, and the pair of sequences is complementary.

[0177] It should be noted that complementarity includes full complementarity or partial complementarity. Among them, full complementarity means a sequence of length N, and all N positions are complementary. Partial complementarity means a sequence of length N, and M (M <= N) positions are complementary, and N - M positions are the same. Or M = M1 + M2, where M1 corresponds to the first M1 positions and M2 corresponds to the last M2 positions.

[0178] Optionally, the LP-SS sequence of the cell can also be obtained based on a predefined rule:

[0179] (1) Define a set or list of LP-SS sequences, and obtain the LP-SS sequence of the cell based on the Cell ID. Such as CellID mod X, where X is the number of sequences in the sequence or list.

[0180] For example, the Cell IDs of multiple cells are (1, 2, 3, 4, 5) respectively. If the number of sequences in the sequence or list is 3 (i.e., sequence 0, sequence 1, and sequence 2), then the LP-SS sequence corresponding to the cell with Cell ID 1 is sequence 1 (1 mod 3 = 1), the LP-SS sequence corresponding to the cell with Cell ID 2 is sequence 2 (2 mod 3 = 2), the LP-SS sequence corresponding to the cell with Cell ID 3 is sequence 0 (3 mod 3 = 0), the LP-SS sequence corresponding to the cell with Cell ID 4 is sequence 1 (4 mod 3 = 1), and the LP-SS sequence corresponding to the cell with Cell ID 5 is sequence 2 (5 mod 3 = 2).

[0181] (2) Obtain the LP-SS sequence of the cell based on part of the cell ID, such as the multi-bit value of the LSB or MSB, and then mod X, where X is the number of sequences in the sequence or list.

[0182] Optionally, the sequence of LP-SS can also be used for the preamble part of LP-WUS.

[0183] 2. Use LP-WUS to carry cell specific wake-up information.

[0184] Among them, based on LP-WUS, a first LP-WUS is defined, that is, the cell specific LP-WUS, which is configured with a first period, a first offset. The LP-WUS carries a first piece of information, that is, wake-up for all UEs, or deactivates the monitoring of LP-WUS. The first LP-WUS is associated with a first PO. Based on LP-WUS, a second LP-WUS is defined, the group specific LP-WUS, that is, it is configured with a second period, a second offset. The LP-WUS carries a second piece of information, that is, the information of the subgroup, or the wake-up information. The second LP-WUS is associated with a second PO.

[0185] Optionally, when both are configured, the first period is greater than, less than or equal to the second period, and the first PO includes the second PO.

[0186] It should be noted that for different WUR types, how to make LP-WUS carry cell specific wake-up information is a problem that needs to be solved. Some specific solutions (Method A and Method B) are provided below:

[0187] Method A: Indicate cell specific wake-up through the payload of LP-WUS.

[0188] For an on-off keying (OOK) receiver, the payload part in LP-WUS indicates all 0s, or all 1s, or a certain value. When taking a certain value at a certain codepoint, it indicates cell specific wake-up.

[0189] For an OOK receiver, a specific OOK ON-OFF pattern / sequence indicates cell specific wake-up.

[0190] For an orthogonal frequency division multiplexing (OFDM) receiver, a specific sequence is used to indicate cell specific wake-up. This sequence is based on a ZC sequence, or an m-sequence, a gold sequence, a PN sequence.

[0191] This sequence is carried on at least one OOK-ON symbol or one OFDM symbol. On the OFDM symbol or OOK-ON symbol of the first LP-WUS.

[0192] For an OFDM receiver, based on a specific phase, a spreading sequence, and a scrambling method, it is used to represent the cell-specific wake-up.

[0193] Method B: The cell-specific wake-up is indicated by a preamble, and the preamble is before the payload.

[0194] For an OOK receiver: The preamble contains at least one sequence of the OOK on-off pattern. For example, 1010101010. One sequence is used to indicate the cell-specific wake-up. Or the preamble is based on a sequence, and the cell-specific wake-up is the complementary sequence of this sequence. For example, 0101010101.

[0195] For an OFDM receiver: Similar to the LP-WUS payload.

[0196] For an OFDM receiver: A specific sequence is used to indicate the cell-specific wake-up. This sequence is based on a ZC sequence, or an m-sequence, a gold sequence, a PN sequence. This sequence is carried on at least one OOK-ON symbol or one OFDM symbol. On the OFDM symbol or OOK-ON symbol of the first LP-WUS.

[0197] For an OFDM receiver: Based on a specific phase, a spreading sequence, and a scrambling method, it is used to represent the cell-specific wake-up.

[0198] It should be noted that in the face of the problem of how LP-WUS indicates a packet, the embodiments of the present disclosure adopt a flexible and configurable indication method, which is beneficial for the base station to configure different LP-WUS packet methods and wake-up methods according to needs in different network load situations.

[0199] In some embodiments, the second low-power signal includes at least one of the following: a first part, a second part, a third part, and padding bits. The first part is used to indicate control information, where the control information includes the number of packets, the number of bit blocks, the wake-up type or the triggered PDCCH monitoring type, the payload size, the format, the pattern, the repetition count, or the indication method; the second part is used to indicate packet information or wake-up information; the third part is used to indicate packet information or wake-up information based on the second part (for example, there are multiple groups including Group 100 and Group 103. If the second part is used to indicate Group 100, the third part indicates Group 103 by indicating the group number difference of 3 between Group 103 and Group 100). The wake-up type includes group wake-up or full wake-up (i.e., the PDCCH monitoring type includes the first PDCCH monitoring or the second PDCCH monitoring).

[0200] In a possible implementation, the second low-power signal includes at least one bit block, and each bit block contains at least 1 bit; or the second low-power signal includes x bits. The indication method for the bit block or x bits is a bitmap method or a code point method.

[0201] In some embodiments, when the control information represents a format or a pattern, the definition of the format or the pattern is based on the value of M, the number of bits carrying information, the repetition count, the sequence type, the sequence length, or the number of sequences, or based on the bit block or x bits.

[0202] In some embodiments, when the control information represents an indication method, the control information is used to interpret the meaning of other bits or other fields. Different values of the control information will interpret the meaning of the corresponding other bits or other fields.

[0203] It should be noted that the code point method means that one value corresponds to at least one packet or UE information, and the wake-up information of at least one packet or UE information. UE information includes UE identification information, RNTI information, etc.

[0204] Optionally, the indication method is determined according to at least one of high-layer configuration, the number of POs, the maximum number of packets, and the payload size of the second low-power signal.

[0205] In the embodiments of the present disclosure, for the determination of the bit block or x bits in the above second low-power signal, the UE can determine the corresponding sequence or sequence set based on the OOK resource position corresponding to the bit block or x bits; or, the sequences or sequence sets determined based on the OOK resource positions of multiple bit blocks or multiple x bits are the same or have a subset relationship. The OOK resource position includes the symbol position of OOK-ON, the symbol position of OOK-OFF, and the time domain or frequency domain resources corresponding to its OOK symbol.

[0206] The content carried by LP-WUS is introduced below with specific examples.

[0207] 1. In the connected state, bit blocks / code points are used for LP-WUS.

[0208] LP-WUS has a total of X bits, where x1 bits correspond to a code point value, or a value, or a block.

[0209] Suppose there are N x1 bits, satisfying X = N * x1 or or x1 < X. At this time, the x1 bits carry identification information, group ID information, and index information, and their quantity is determined according to the configuration of higher-layer parameters.

[0210] If carrier aggregation (CA) is not considered in the x1 bits at this time, then by default it is applied to all Scells. If CA is considered, then in addition to the x1 bits, each block also considers including some bits s to indicate the SCell group with bitmap, and whether there are these bits depends on the configuration of higher-layer parameters.

[0211] Exemplarily, as Figure 4 shown, it shows the arrangement of the content carried by LP-WUS.

[0212] Optionally, there are also x0 bits used to indicate whether to activate the first timer or the second timer. It may also not exist. Or the x0 bits are used to indicate whether the following bits are the C-RNTI, or the configured identification information, group ID information, and index information.

[0213] When the total number of bits in all blocks is less than the LP-WUS payload size configured by RRC, padding bits are required.

[0214] Optionally, the bit block includes x1 bits for one group or for one UE. The x1 bits are determined according to a higher layer parameter, such as 1, 2, 3, 4, or 5 bits. Each bit corresponds to one SCell group(s) or a UE. The bits from the most significant bit (MSB) to the least significant bit (LSB) correspond to the first to the last SCell group(s) or UE, which are in descending or ascending order.

[0215] Optionally, the position or starting position of the bit block can be determined by a higher layer parameter, and the range indicated by this parameter is 0 to X - 1.

[0216] Similarly, the following LP-WUS payload structure in the idle state can also be considered in the connected state.

[0217] 2. In the idle / inactive state, the number of packets indicated by LP-WUS can be configured by the base station.

[0218] (1) The number of packets that LP-WUS supports for wake-up.

[0219] When the maximum number of groups corresponding to each PO configured by the higher layer is 8, LP-WUS uses 8 bits to indicate the corresponding 8 packets. And LP-WUS can also use 16 bits to correspond to a total of 16 groups of 2 POs, or use 24 bits to correspond to 24 groups of 3 POs.

[0220] When the maximum number of groups corresponding to each PO configured by the higher layer is 16, LP-WUS satisfies any of the following characteristics:

[0222] Characteristic 2: LP-WUS uses 8 bits to indicate 2, 4, 6, 8, 10, 12, 14, or 16 subgroups in 16 groups, that is, each bit corresponds to 2 subgroups, and every 8 bits correspond to one PO.

[0223] Characteristic 3: LP-WUS uses 16 bits to indicate 1 to 7 groups or 9 to 16 groups in 16 groups of one PO. Or use 16 bits to indicate 1, 2, 3, 4, 32, 31, 30, 29 groups in 32 groups of 2 POs. Preferably 1, 2, 3, 4, 32.

[0224] Feature 4: When LP-WUS uses 24 bits to indicate 32 groups of 2 POs, it supports 1 to 8 and 32 groups of wake-up.

[0254] (4) The LP-WUS uses 24 bits to indicate at least one group among two POs, and supports the LP-WUS to indicate 1 to 2,2048 groups.

[0255] When the maximum number of groups corresponding to each PO configured by the upper layer is 2048:

[0256] (1) The LP-WUS uses 16 bits to indicate at least one group in one PO, and supports the LP-WUS to indicate 1 to 2,048 groups.

[0257] (2) The LP-WUS uses 16 bits to indicate at least one group among two POs, and supports the LP-WUS to indicate 1 to 4,096 groups.

[0258] (3) The LP-WUS uses 24 bits to indicate at least one group in one PO, and supports the LP-WUS to indicate 1 to 2,2048 groups.

[0259] (4) The LP-WUS uses 24 bits to indicate at least one group among two POs, and supports the LP-WUS to indicate 1 to 4,096 groups.

[0260] When the maximum number of groups corresponding to each PO configured by the upper layer is 4096:

[0261] (1) The LP-WUS uses 16 bits to indicate at least one group in one PO, and supports the LP-WUS to indicate 1 to 4,096 groups.

[0262] (2) The LP-WUS uses 16 bits to indicate at least one group among two POs, and supports the LP-WUS to indicate 1 to 8,192 groups.

[0263] (3) The LP-WUS uses 24 bits to indicate at least one group in one PO, and supports the LP-WUS to indicate 1 to 4,096 groups.

[0264] (4) The LP-WUS uses 24 bits to indicate at least one group among two POs, and supports the LP-WUS to indicate 1 to 8,192 groups.

[0265] That is to say, the supported number of groups:

[0266] When the number of POs M corresponding to the maximum number of groups N* configured by the upper layer <= the number of groups X determined by the payload size of LP-WUS, such as 2^X, the bitmap method is used. In this case, the supported number of groups is 1 to M*N;

[0267] When the number of POs M corresponding to the maximum number of groups N* configured by the upper layer > the number of groups X determined by the payload size of LP-WUS, such as 2^X, the codepoint method is used.

[0268] The number of groups indicated by LP-WUS is determined as follows:

[0269] The supported number of groups includes or and M*N groups.

[0270] (2) Method for LP-WUS to indicate grouping:

[0271] When the number of POs M corresponding to the maximum number of groups N* configured by the upper layer <= the number of groups X determined by the payload size of LP-WUS, such as 2^X, the bitmap method is used.

[0272] When the number of POs M corresponding to the maximum number of groups N* configured by the upper layer > the number of groups X determined by the payload size of LP-WUS, such as 2^X, and log2(M*N) < X, the codepoint method is used.

[0273] Assume Then the LP-WUS of X bits contains the indication of n group IDs

[0274] Exemplarily, as Figure 5 shown, it shows the arrangement of bits corresponding to different subgroup IDs in LP-WUS.

[0275] Optionally, the following parts may be included in the remaining bits:

[0276] (1) Based on a group ID of x1 bits, increase or decrease the offset of the group ID to obtain the third grouping ID. Assume this field is the second field of the group ID and has x2 bits. The first field is the field corresponding to x1 bits. The second field may or may not exist.

[0277] (2) When the payload of the first field and the second field together is less than X bits, additional padding bits are required.

[0278] It should be noted that the above satisfies n * x1 + x2 + padding bits = X, where n >= 1.

[0279] It should be noted that there is a potential problem with padding bits. It may not be clear to the UE where the padding bits are. Special designs are required, such as consecutive multiple OOK off symbols + ON - OFF patterns, or specific sequences that vary according to length / number of bits.

[0280] (3) Cell - specific LP - WUS for wake - up or variable - length LP - WUS:

[0281] In addition, there may be another field, x0 bits, in the lP - WUS. The x0 bits are used to indicate whether it is a group - specific wake - up or a cell - specific wake - up. The special design of the padding bits can also be achieved. That is, different preambles of the padding bits are used to indicate whether it is group - specific or cell - specific.

[0282] Use the preamble of the LP - WUS to indicate whether it is a group - specific wake - up or a cell - specific wake - up, as well as the payload size of the LP - WUS, or the format of the LP - WUS.

[0283] Exemplarily, as Figure 6 shown, it shows the arrangement of the x0 bits in the LP - WUS.

[0284] It should be noted that if only legacy C-DRX-based PDCCH monitoring is supported, there is a PSG but no latency gain. If only using LP-WUS to trigger a new active time or PDCCH monitoring is supported, the legacy C-DRX active time still needs to wake up, in which case there is a latency gain but no PSG. And only one of the above two can be applied through high-layer configuration, which makes it impossible to balance the latency gain and PSG. Embodiments of the present disclosure determine whether the triggered PDCCH monitoring is the first PDCCH monitoring or the second PDCCH monitoring based on LP-WUS or a predefined rule, which helps to flexibly switch between different PDCCH monitorings or different active times, and then combines the above two and flexibly switches one of the methods, which helps to obtain both PSG and latency gain.

[0285] In some embodiments, the above UE processing signals or channels based on low-power signals may further include: the UE determines that the triggered PDCCH monitoring is the first PDCCH monitoring or the second PDCCH monitoring based on the low-power signal.

[0286] Among them, the first PDCCH monitoring is based on a first monitoring duration, a first timer, a first inactive timer, a first retransmission timer, or a first offset. The second PDCCH monitoring is based on a C-DRX cycle, a second timer, a second inactive timer, a second retransmission timer, or a second offset.

[0287] As a possible implementation, for the UE to determine that the triggered PDCCH monitoring is the first PDCCH monitoring or the second PDCCH monitoring based on the low-power signal, it may be at least one of the following:

[0288] (1) The UE determines that the triggered PDCCH monitoring is the first PDCCH monitoring or the second PDCCH monitoring based on the indication of the low-power signal; or,

[0289] (2) The UE determines that the triggered PDCCH monitoring is the first PDCCH monitoring or the second PDCCH monitoring based on the position of the low-power signal;

[0290] (3) The UE determines that the triggered PDCCH monitoring is the first PDCCH monitoring or the second PDCCH monitoring based on a predefined rule and the low-power signal.

[0291] In the embodiments of the present disclosure, for the UE to determine that the triggered PDCCH monitoring is the first PDCCH monitoring or the second PDCCH monitoring based on predefined rules and low-power signals or the location of the low-power signals, it may include at least one of the following:

[0292] (1) The UE determines to trigger the second PDCCH monitoring when a low-power signal is received within the first time period. The first time period is a period of time before the second PDCCH monitoring, or a period of time before the start of the second timer, or a period of time before the second offset;

[0293] (2) When a low-power signal is received during a non-first time period, the UE determines to trigger the first PDCCH monitoring. The non-first time period is other time except the first time period, or other time except the first time period within a cycle;

[0294] (3) When a low-power signal is received after the first time node, the UE determines to trigger the second PDCCH monitoring. The first time node is before the second PDCCH monitoring, before the start of the second timer, or before the second offset;

[0295] (4) When a low-power signal is received before the first time node, the UE determines to trigger the first PDCCH monitoring. The first time node is periodic, or based on the C-DRX cycle, or within a C-DRX cycle.

[0296] It should be noted that in the embodiments of the present disclosure, the second low-power signal is determined based on higher-layer signaling to trigger the first PDCCH monitoring or the second PDCCH monitoring.

[0297] The following introduces the flexible switching of different PDCCH monitorings in combination with specific examples.

[0298] Trigger legacy C-DRX related timer or PDCCH monitoring based on LP-WUS, RRC signaling or predefined rules.

[0299] Method 1: Trigger the first PDCCH monitoring or the second PDCCH monitoring with LP-WUS.

[0300] Method 2: Configure LP-WUS with RRC signaling to trigger the first PDCCH monitoring or the second PDCCH monitoring

[0301] Method 3: Based on predefined rules, trigger the first PDCCH monitoring or the second PDCCH monitoring after receiving LP-WUS.

[0302] Among them, the first PDCCH monitoring is triggered by the first timer, and the second PDCCH monitoring is triggered by the second timer. The first PDCCH monitoring is performed during the first active time, and the second PDCCH monitoring is performed during the second active time. The first PDCCH monitoring is triggered based on LP-WUS, or based on the first timer, or based on PDCCH monitoring for a period of time / a window / a certain number of PDCCH occasions. The second PDCCH monitoring is triggered based on C-DRX related timers (the second timer). The start times of the first timer and the second timer are configured separately or differently. The durations of the second timer and the second timer duration are configured separately or differently.

[0303] The above Method 1 and Method 3 are specifically described below.

[0304] Method 1: Use 1 bit of LP-WUS for indication. For example, '0' indicates triggering the first PDCCH monitoring, and '1' indicates triggering the second PDCCH monitoring. This 1 bit satisfies the following characteristics:

[0305] (1) This 1 bit is the MSG, the first bit, or this 1 bit is the LSB, the last bit, or the MSB or LSB of the block.

[0306] (2) This 1 bit acts on one or more UEs, one or more groups.

[0307] (3) In LP-WUS, one bit block includes 1 bit + bitmap.

[0308] (4) In LP-WUS, LP-WUS includes one bit and X bits corresponding to at least one code point.

[0309] Optionally, trigger the first PDCCH monitoring with the first code point of LP-WUS, and repeatedly trigger the second PDCCH monitoring with the second code point of LP-WUS.

[0310] Method 3: Based on predefined rules, upon receiving an LP-WUS, trigger the first PDCCH monitoring or the second PDCCH monitoring. The predefined rules are mainly based on the time-domain position.

[0311] Among them, the predefined rules include:

[0312] (1) The LP-WUS received within a period of time before the offset is used to trigger the second PDCCH monitoring, or the LP-WUS received at the LO, monitoring occasion in other time-domain positions is used to trigger the first PDCCH monitoring.

[0313] (2) The LP-WUS received within a period of time before the start of the duration-on timer is used to trigger the second PDCCH monitoring, or the LP-WUS received at the LO, monitoring occasion in other time-domain positions is used to trigger the first PDCCH monitoring.

[0314] Exemplarily, as Figure 7 shown, it shows the triggering mechanism for the first PDCCH monitoring or the second PDCCH monitoring.

[0315] It should be noted that for Methods 1-3 in the above embodiments, Method 1 and Method 3 are more flexible than Method 2.

[0316] It should be noted that in some embodiments, monitoring, detecting, and receiving are equivalent or can be mutually replaced.
