[0039] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0040] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. 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 in the embodiments of this application are also applicable to similar technical problems.

[0041] 1) Communication system scenario

[0042] Communication system scenarios can include terrestrial networks (TN) and non-terrestrial networks (NTN). NTN typically uses satellite communication to provide services to terrestrial users. Current NTN systems include New Radio (NR)-NTN and Internet of Things (IoT)-NTN systems, and other NTN systems may be included in the future.

[0043] For example, Figure 1A is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. As shown in Figure 1A, the communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal device, terminal device). The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminal devices located within that coverage area.

[0044] Figure 1A exemplarily illustrates a network device and two terminal devices. In some embodiments, the communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area. This application does not limit this.

[0045] For example, Figure 1B is a schematic diagram of another communication system architecture provided in an embodiment of this application. Referring to Figure 1B, it includes a terminal device 120 and a satellite 130, which can communicate wirelessly. The network formed between the terminal device 120 and the satellite 130 can also be called an NTN. In the communication system architecture shown in Figure 1B, the satellite 130 can function as a base station, and the terminal device 120 and the satellite 130 can communicate directly. In this system architecture, the satellite 130 can be referred to as a network device. In some embodiments of this application, the communication system may include multiple network devices, and the coverage area of ​​each network device may include other numbers of terminal devices; this application does not limit this aspect.

[0046] For example, Figure 1C is a schematic diagram of another communication system architecture provided in an embodiment of this application. Referring to Figure 1C, it includes a terminal device 120, a satellite 130, and a base station 140. Wireless communication is possible between the terminal device 120 and the satellite 130, and communication is possible between the satellite 130 and the base station 140. The network formed between the terminal device 120, the satellite 130, and the base station 140 can also be called an NTN. In the architecture of the communication system shown in Figure 1C, the satellite 130 may not have the function of a base station, and communication between the terminal device 120 and the base station 140 needs to be relayed through the satellite 130. In this system architecture, the base station 140 can be referred to as a network device. In some embodiments of this application, the communication system may include multiple network devices, and the coverage area of ​​each network device may include other numbers of terminal devices; this application does not limit this.

[0047] In future communication systems such as Beyond Fifth Generation (B5G) and 6th Generation (6G), there may also be Distributed Multiple-In Multiple-Out (DMIMO, also known as distributed antenna systems) and / or Massive Multiple-In Multiple-Out (MMIMO, also known as massive antenna matrix systems) scenarios. In some cases, Distributed MIMO and / or Massive MIMO may also support cell-free or UE-centric network deployment scenarios. It should be understood that the above scenarios also apply to TN and / or NTN.

[0048] 2) 5G Radio Resource Control (RRC) Status

[0049] Currently, with people's pursuit of speed, latency, high-speed mobility, and energy efficiency, as well as the diversity and complexity of services in future life, the 3GPP international standards organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC).

[0050] eMBB still aims to provide users with multimedia content, services, and data, and its demand is growing rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, its capabilities and needs vary considerably. Therefore, generalizations cannot be made; a detailed analysis based on the specific deployment scenario is necessary. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance. Typical characteristics of mMTC include high connection density, small data volume, latency-insensitive services, low module cost, and long module lifespan.

[0051] NR can also be deployed independently. In 5G network environments, to reduce air interface signaling and quickly restore wireless connections and data services, a new RRC state, namely the RRC_INACTIVE state, is set. This state is different from the RRC_IDLE and RRC_ACTIVE states.

[0052] RRC_IDLE: Mobility is UE-based cell selection reselection, paging is initiated by the CN, and the paging area is configured by the CN. There is no UE AS context on the base station side. There is no RRC connection.

[0053] RRC_CONNECTED: An RRC connection exists, and the base station and UE share an Access Stratum (AS) context. The network knows the UE's location at the cell level. Mobility is network-controlled. Unicast data can be transmitted between the UE and the base station.

[0054] RRC_INACTIVE: Mobility is based on UE cell selection reselection, there is a connection between the Core Network (CN) and the NR, the UE AS context exists on a certain base station, paging is triggered by the Radio Access Network (RAN), the paging area based on the RAN is managed by the RAN, and the network side knows the UE's location at the RAN-based paging area level.

[0055] 3) 5G terminal energy-saving project

[0056] Terminal power-saving technologies include optimizing power consumption in idle / inactive and connected modes. The 5G UE power-saving project has proposed different improvement schemes in the following versions:

[0057] R16:

[0058] For connected mode, a Wake-Up Signal (WUS) is introduced to indicate when the UE starts discontinuous reception (DRX) on-duration, thereby reducing unnecessary physical downlink control channel (PDCCH) monitoring.

[0059] For Carrier Aggregation (CA), SCell dormancy is introduced to reduce PDCCH monitoring on SCells.

[0060] R17:

[0061] For idle / inactive modes, an early paging indication (PEI) is introduced to indicate whether the UE needs to monitor paging, thereby reducing unnecessary paging monitoring.

[0062] For connection mode, PDCCH skipping and Search Space Set Group (SSSG) switching are introduced to reduce unnecessary PDCCH monitoring for the UE.

[0063] R18, R19:

[0064] TR 38.869 summarizes the research results of R18 LP-WUS, which assumes that the UE has a low-power radio (LR) and a main radio (MR). Compared with WUS in R16 and PEI in R17, low-power WUS is more energy-efficient, as it uses a single, lower-power receiver, i.e., it does not use a main transceiver. The main transceiver is only activated after the terminal receives LP-WUS to listen for downlink signals, thus achieving energy saving.

[0065] Please refer to Figure 2, which illustrates the working principle of LP-WUS in the 5G system involved in this application; as shown in Figure 2, for idle / inactive mode, MR paging monitoring can be triggered by LP-WUS. For connected mode, MR PDCCH monitoring can be triggered by LP-WUS.

[0066] Through these technologies, the 5G UE power saving project aims to enable terminals to reduce power consumption as much as possible and extend battery life without affecting performance and service quality.

[0067] 4) 5G network energy-saving projects

[0068] To reduce the energy consumption of 5G networks, wireless communication systems need to implement energy-saving technologies in the time, frequency, space, and power domains. These technologies include the following:

[0069] R18:

[0070] Enhanced adaptive Channel State Information (CSI) in both the spatial and power domains allows network devices to adjust beamforming and transmit power based on channel conditions and data transmission requirements, thereby improving energy efficiency.

[0071] The time-domain Discontinuous Transmission (DTX) / DRX mechanism allows network devices to dynamically adjust cell status based on traffic load and coverage requirements, enabling inactive cells to enter low-power mode and reducing static power consumption.

[0072] Cross-band CA SSB-less SCell operation allows network devices to avoid sending SSB signals in secondary cells, reducing signaling overhead and power consumption, while ensuring the connection performance and reliability of the primary cell.

[0073] R19:

[0074] In connected mode, UEs configured with CA can perform on-demand transmission of SSB SCells. Network devices can dynamically determine whether to send SSB signals, as well as the time slots and periods of transmission, based on the UE's location and speed, further improving the energy efficiency of cross-band CA.

[0075] In idle / inactive mode, the system information block (SIB) 1 is transmitted on demand. The network device can dynamically decide whether to send the SIB1 signal, as well as the time slot and period of transmission, based on the UE's mobility and service type, thereby reducing the scanning and search overhead in idle mode.

[0076] Through these technologies, 5G network energy-saving projects aim to reduce energy consumption, lower operating costs, and improve environmental sustainability as much as possible without affecting coverage and capacity.

[0077] In next-generation networks, a major research direction is achieving joint energy saving for terminals and network devices. Please refer to Figure 3, which illustrates the working principle of LP-WUS in the 6G system involved in this application embodiment. As shown in Figure 3, the terminal and network sides each have a low-power receiver (LR) and a low-power receiver (MR). The LR operating mode can be understood as a low-power receiver mode (only receiving function), where the terminal and / or network device consumes less power but can only perform simpler functions. The MR can be understood as a high-power or full-function mode (including transmit and receive functions), where the terminal and / or network device consumes more power but can perform more complex functions. The design goal is to enable the terminal and network devices to flexibly switch between these two modes. To achieve this goal, the terminal and network operate in a "low-power / low-power mode" in power-saving mode, and activate a "big core mode or high-power / high-power mode" by sending an "indication message" from one side to the other.

[0078] In some embodiments, a network energy-saving pattern can be configured so that the terminal's transmission and reception are matched with the network energy-saving pattern, thereby minimizing the power consumption of both the terminal and the network. Please refer to Figure 4, which illustrates a schematic diagram of an energy-saving mode related to this application. As shown in Figure 4, the network may periodically wake up at specific times to receive or transmit corresponding uplink or downlink signals / data. Through reasonable configuration or scheduling, the UE can receive or transmit data during the network's periodic wake-up periods, thus minimizing network and / or terminal power consumption.

[0079] However, this periodic wake-up pattern also presents a problem: for the terminal, the arrival of uplink services is unpredictable. Generally, for non-urgent services, the terminal can wait for the next network wake-up cycle to send uplink data based on the network-configured pattern. However, for urgent or latency-sensitive services, the periodic pattern can lead to unmet service quality requirements.

[0080] Please refer to Figure 5, which shows a flowchart of a wireless communication method provided in an embodiment of this application. This method can be executed by a terminal device, wherein the terminal device can be terminal device 120 in the aforementioned network architecture, or a terminal device in other network architectures; this application is not limited in this regard. The method may include at least some of the following steps:

[0081] Step 510: Receive wake-up configuration information sent by the network device.

[0082] In some embodiments, the terminal device may receive wake-up configuration information sent by the network device via broadcast; for example, the terminal device may detect and receive the SSB sent by the network device and obtain the wake-up configuration information carried in the SSB.

[0083] In some embodiments, the terminal device may receive wake-up configuration information sent by the network device during random access. For example, the terminal device may receive wake-up configuration information sent by the network device through random access messages (such as Msg.2 or Msg4).

[0084] In some embodiments, the terminal device can receive wake-up configuration information sent by the network device in RRC connected state. For example, the terminal device can receive wake-up configuration information sent by the network device through RRC signaling.

[0085] Step 520: Based on the wake-up configuration information, send an uplink wake-up signal to the network device when the network device is in power-saving mode; the uplink wake-up signal is a sequence-based signal.

[0086] In some embodiments, the aforementioned uplink wake-up signal may be a signal consisting of a sequence of 0s and 1s.

[0087] In some embodiments, the aforementioned uplink wake-up signal is used to trigger the network device to exit the power-saving state and / or enter the receiving state.

[0088] The energy-saving state of the aforementioned network equipment can refer to the state in which the network equipment transmits and receives signals through a low-power receiver. For example, the energy-saving state of the network equipment means that the main radio of the network equipment is turned off and a low-power receiver is used for reception. The energy-saving state of the network equipment can also be referred to as low-power state / running in low-power mode / sleep state / non-wake-up state, etc.

[0089] The receiving status of the aforementioned network device can refer to the state in which the network device transmits and receives signals through the main transceiver; the receiving status of the aforementioned network device can also be referred to as non-energy-saving state / high-power state / running in high-power mode / wake-up state / non-sleep state, etc.

[0090] In this embodiment of the application, when the network device is in an energy-saving state, if the terminal device needs to communicate with the network device, such as when data with high timeliness needs to be transmitted, it can send an uplink wake-up signal to the network device according to the above wake-up configuration information to wake up the network device and thus communicate with the network device.

[0091] The solution provided in this application allows network devices to be set to energy-saving and non-energy-saving states, and to indicate wake-up configuration information to terminal devices. When the network device is in energy-saving state, the terminal device can send a sequence-based uplink wake-up signal to the network device to wake it up, based on the wake-up configuration information. In this solution, the energy-saving state of the network device can improve its energy-saving effect. The network device can instruct the terminal device to wake it up using a sequence-based signal when it is in energy-saving state, ensuring the flexibility and controllability of the terminal device in waking up the network device. At the same time, the power consumption required for the detection and reception of sequence-based signals is relatively small, which can ensure the energy-saving effect of the network device. Therefore, the above solution can balance the energy-saving effect and communication performance of the network device, improving the communication efficiency of the system.

[0092] Please refer to Figure 6, which shows a flowchart of a wireless communication method provided in an embodiment of this application. This method can be executed by a network device, wherein the network device can be network device 110, satellite 130, or base station 140 in the aforementioned network architecture, or other communication devices; this application is not limited in this regard. The method may include at least some of the following steps:

[0093] Step 610: Send wake-up configuration information to the terminal device; the wake-up configuration information is used to instruct the terminal device to send an uplink wake-up signal to the network device when the network device is in power-saving mode; the uplink wake-up signal is a sequence-based signal.

[0094] In some embodiments, a network device may send wake-up configuration information to a terminal device via broadcast; for example, the network device may send an SSB, which carries the wake-up configuration information.

[0095] In some embodiments, the network device may send wake-up configuration information to the terminal device during random access. For example, the network device may send wake-up configuration information through random access messages (such as Msg.2 or Msg4).

[0096] In some embodiments, the network device can send wake-up configuration information to the terminal device when the terminal device is in RRC connected state. For example, the network device can send wake-up configuration information to the terminal device through RRC signaling.

[0097] In summary, the solution provided by this application allows network devices to be set to energy-saving and non-energy-saving states, and to indicate wake-up configuration information to terminal devices. When the network device is in energy-saving state, the terminal device can send a sequence-based uplink wake-up signal to the network device to wake it up, based on the wake-up configuration information. In this solution, the energy-saving state of the network device can improve its energy-saving effect. The network device can instruct the terminal device to wake it up using a sequence-based signal when it is in energy-saving state, ensuring the flexibility and controllability of the terminal device in waking up the network device. Furthermore, the power consumption required for detecting and receiving sequence-based signals is relatively low, ensuring the energy-saving effect of the network device. Therefore, this solution can balance the energy-saving effect and communication performance of the network device, improving the communication efficiency of the system.

[0098] Based on the schemes shown in Figures 5 and 6, please refer to Figure 7, which shows a schematic diagram of a network device wake-up according to an embodiment of this application.

[0099] As shown in part (a) of Figure 7, when the network device is in the transmit / receive state, it can send wake-up configuration information 710 to the terminal device. The wake-up configuration information 710 indicates that the terminal device can wake up the network device when the network device is in the power-saving state later.

[0100] As shown in part (b) of Figure 7, after the network device enters the power saving state, the terminal device receives uplink data 720 that needs to be sent. At this time, the terminal device can send an uplink wake-up signal 730 to the network device according to the wake-up configuration information 710 mentioned above. After the low-power transceiver of the network device receives the uplink wake-up signal 730, it triggers the main transceiver to wake up.

[0101] As shown in part (c) of Figure 7, the low-power receiver of the network device receives the uplink wake-up signal 730, wakes up the master transceiver, and the master transceiver receives the uplink data 720 transmitted by the terminal device.

[0102] Based on the schemes shown in Figures 5 and 6, please refer to Figure 8, which illustrates a flowchart of a wireless communication method provided in an embodiment of this application. This method can be interactively executed by a terminal device and a network device. The terminal device can be terminal device 120 in the aforementioned network architecture, or other communication devices. The network device can be network device 110, satellite 130, or base station 140 in the aforementioned network architecture, or other communication devices. This method may include at least some of the following steps:

[0103] Step 810: The network device sends wake-up configuration information to the terminal device; the terminal device receives the wake-up configuration information.

[0104] In some embodiments, the network device may send wake-up configuration information to the terminal device via at least one of broadcast, random access message, and RRC message.

[0105] For example, a network device can carry complete wake-up configuration information in at least one of the following messages: SSB, random access message, and RRC message. Alternatively, a network device can carry partial information from the wake-up configuration information in at least two of the following messages: SSB, random access message, and RRC message.

[0106] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, the wake-up configuration information is used to configure at least one of the following information:

[0107] 1) Configuration information for the wake-up cycle of network devices.

[0108] The aforementioned wake-up cycle refers to the cycle in which network devices enter power-saving mode and transmit / receive mode. In other words, the aforementioned network devices can periodically enter power-saving mode and non-power-saving mode.

[0109] The configuration information for the wake-up cycle of the aforementioned network devices can be used to configure relevant information about the wake-up cycle of the network devices, such as the start time, end time period, and cycle duration.

[0110] 2) Configuration information for the transmission of uplink wake-up signals.

[0111] The configuration information for the transmission of the uplink wake-up signal can be used to configure the transmission method of the uplink wake-up signal, such as how to transmit it and when to transmit it.

[0112] 3) Configuration information for the triggering conditions of the uplink wake-up signal.

[0113] The triggering conditions mentioned above refer to the conditions that the terminal device must meet to send an uplink wake-up signal.

[0114] The configuration information for the triggering conditions of the aforementioned uplink wake-up signal can be used to configure the conditions that allow the terminal device to send the uplink wake-up signal. In other words, the terminal device can send the uplink wake-up signal when the triggering conditions indicated by the configuration information for the aforementioned triggering conditions are met.

[0115] In the scheme shown in the embodiments of this application, on the one hand, the network device can configure the wake-up cycle of the network device to the terminal device, so that the terminal device can clearly know which time periods the network device is in energy-saving state, and thus send the uplink wake-up signal within the accurate time period; on the other hand, the network device can configure the transmission-related information of the uplink wake-up signal to the terminal device, so that the network device and the terminal device can clearly define the transmission method of the uplink wake-up signal, ensuring the accuracy and efficiency of the uplink wake-up signal transmission; furthermore, the network device can configure the transmission conditions of the uplink wake-up signal to the terminal device, so that the terminal device executes the transmission of the uplink wake-up signal when the conditions are met, avoiding unnecessary wake-ups of the network device and ensuring the energy-saving effect of the network device.

[0116] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, the configuration information of the wake-up period of the network device is used to indicate at least one of the following:

[0117] The time period during which network equipment is in energy-saving mode;

[0118] The time period during which the network device is in the sending and receiving state.

[0119] In some embodiments, a wake-up cycle of a network device can be divided into one or more power-saving time periods and one or more transmit / receive time periods, wherein the power-saving time period may be the time period during which the network device is in power-saving mode, and the transmit / receive time period may be the time period during which the network device is in transmit / receive mode.

[0120] In this embodiment, the configuration information of the wake-up cycle of the network device may include or indicate the start time of the wake-up cycle, the cycle length, the time domain offset of the start time of the aforementioned energy-saving time period relative to the start time of the wake-up cycle, the duration of the energy-saving time period, the time domain offset of the start time of the aforementioned transmit / receive time period relative to the start time of the wake-up cycle, and the duration of the transmit / receive time period, etc. This allows the terminal device to determine, through the configuration information of the wake-up cycle of the network device, which time periods the network device is / may be in energy-saving state and which time periods it is / may be in wake-up state. The terminal device can send an uplink wake-up signal during the time periods when the network device is / may be in energy-saving state, thereby ensuring that the uplink wake-up signal is sent within the accurate time period and avoiding the transmission of invalid uplink wake-up signals.

[0121] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, the configuration information for the transmission of the uplink wake-up signal includes at least one of the following: transmission resources for the uplink wake-up signal; signal type of the uplink wake-up signal.

[0122] In the embodiments of this application, the transmission resources of the aforementioned uplink wake-up signal may include at least one of frequency domain resources, time domain resources, time-frequency resource set, and transmission timing / transmission opportunity.

[0123] In this embodiment, the signal type of the uplink wake-up signal may include at least one of the following: LP-WUS wake-up signal types (such as Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK)), On-Off Keying (OOK), or Orthogonal Frequency Division Multiplexing (OFDM) overlaid with OOK wake-up signal types. For example, the uplink wake-up signal may be a sequence signal, and its type may be a sequence type and / or a modulation type.

[0124] For example, to achieve power saving in low-power receivers, these receivers require lower complexity. Therefore, the waveform of the uplink wake-up signal can be a waveform like ASK or FSK, which can be detected by receivers with low complexity. The ASK waveform typically uses the OOK signal. In some embodiments, to utilize an OFDM transmitter to generate the uplink wake-up signal and reduce additional hardware overhead, the OOK signal is generated using multi-carrier (MC) modulation, hence the name MC-OOK signal. The MC-OOK signal can be generated using existing multi-carrier modulation such as OFDM modulation, maintaining good compatibility with OFDM systems and reducing the transmitter complexity introduced by implementing the uplink wake-up signal.

[0125] The waveform of the aforementioned uplink wake-up signal can be an MC-ASK waveform. Taking K as the number of IDFT points and N as the number of subcarriers used to transmit the WUS signal as an example, the MC-ASK waveform can be generated in the following ways:

[0126] OOK-1: Each OFDM symbol carries 1 bit. The output signal corresponding to the subcarrier carrying the uplink wake-up signal after modulation and IDFT transformation is OOK=1, and the output signal corresponding to the subcarrier carrying the uplink wake-up signal having zero power is OOK=0.

[0127] OOK-2: Each OFDM symbol carries M bits in the frequency domain. The N subcarriers carrying the uplink wake-up signal are divided into M segments, each carrying 1 bit of information. In each segment, the output signal corresponding to all subcarriers being modulated is OOK = 1, and the output signal corresponding to all subcarriers being at zero power is OOK = 0.

[0128] OOK-3: Each OFDM symbol carries 1 bit. The N subcarriers carrying the uplink wake-up signal are divided into M segments. In each of the M segments, when one subcarrier in each segment is modulated and the other subcarriers are at zero power, the corresponding output signal is OOK = 1. When all subcarriers in all segments are at zero power, the corresponding output signal is OOK = 0.

[0129] OOK-4: Each OFDM symbol carries M bits in the time domain. N subcarriers carrying the uplink wake-up signal are generated through DFT, and M bits are represented by S sampling points. The S sampling points are transformed by DFT to form S subcarriers. The S subcarriers are truncated and processed to form N subcarriers, which are then transformed by IDFT to generate the OOK signal.

[0130] In addition to the MC-ASK waveform, the uplink wake-up signal can also use the MC-FSK waveform, which can include the following methods:

[0131] FSK-1: The N subcarriers carrying the uplink wake-up signal are divided into M pairs of segments. In each OFDM symbol, one segment in each pair is modulated, and the other segment is at zero power.

[0132] FSK-2: The N subcarriers carrying the uplink wake-up signal are divided into 2M segments. In each OFDM symbol, one segment of the 2M segments is modulated, and the other segments are at zero power.

[0133] In this embodiment, the network device can indicate the transmission resources and / or signal type of the uplink wake-up signal to the terminal device through wake-up configuration information, thereby enabling the terminal device to transmit the uplink wake-up signal on the accurate resources, and / or enabling the terminal device to transmit the uplink wake-up signal with the accurate signal type. The network device can receive the specified type of uplink wake-up signal on the corresponding transmission resources, ensuring the controllability of the uplink wake-up signal transmission, thereby ensuring the transmission efficiency and accuracy of the uplink wake-up signal.

[0134] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, the configuration information of the uplink wake-up signal triggering condition is used to indicate at least one of the following:

[0135] 1) The data type of the uplink data that triggers the uplink wake-up signal.

[0136] In some embodiments, the data type of the aforementioned uplink data can be classified according to the service or latency requirements corresponding to the uplink data.

[0137] For example, when categorizing data by business function, the data types of the aforementioned uplink data can be divided into audio and video data, XR data, IoT data, eMBB data, mMTC data, URLLC data, and so on.

[0138] For example, when classifying data according to latency requirements, the data types of the aforementioned upstream data can be divided into latency-sensitive data and non-latency-sensitive data, etc.

[0139] In some embodiments, the configuration information of the triggering condition of the wake-up signal can explicitly indicate the data type of the uplink data that triggers the uplink wake-up signal. For example, the configuration information of the triggering condition of the wake-up signal can carry an indicator bit of the data type of the uplink data that triggers the uplink wake-up signal.

[0140] In some embodiments, the configuration information of the triggering condition of the wake-up signal can implicitly indicate the data type of the uplink data that triggers the uplink wake-up signal. For example, the data type of the uplink data that triggers the uplink wake-up signal can be associated with at least one of the scrambling code sequence of the signal in which the configuration information of the triggering condition of the wake-up signal is located and the resource location.

[0141] 2) The logical channel where the uplink data that triggered the uplink wake-up signal is located.

[0142] For example, data of different types (such as different latency-sensitive data) can be mapped to different logical channels; in the embodiments of this application, the configuration information of the triggering condition of the uplink wake-up signal can indicate the logical channel where the uplink data that triggers the uplink wake-up signal is located.

[0143] In some embodiments, the configuration information of the triggering condition of the wake-up signal can display an indication of the logical channel where the uplink data that triggers the uplink wake-up signal is located. For example, the configuration information of the triggering condition of the wake-up signal can carry an indication bit of the logical channel where the uplink data that triggers the uplink wake-up signal is located.

[0144] In some embodiments, the configuration information of the triggering condition of the wake-up signal can implicitly indicate the logical channel where the uplink data that triggers the uplink wake-up signal is located. For example, the logical channel where the uplink data that triggers the uplink wake-up signal is located can be associated with at least one of the scrambling code sequence of the signal and the resource location of the signal in which the configuration information of the triggering condition of the wake-up signal is located.

[0145] 3) The latency requirement of the uplink data that triggers the uplink wake-up signal.

[0146] In this embodiment of the application, the urgency of uplink data transmission varies depending on the latency requirements. Accordingly, uplink data with lower latency requirements may not trigger the uplink wake-up signal, while uplink data with higher latency requirements may trigger the uplink wake-up signal. The network device can indicate the latency requirements of the uplink data that triggers the uplink wake-up signal to the terminal device through the configuration information of the triggering conditions of the uplink wake-up signal.

[0147] In some embodiments, the configuration information of the triggering condition of the wake-up signal can display an indication of the delay requirement of the uplink data that triggers the uplink wake-up signal. For example, the configuration information of the triggering condition of the wake-up signal can carry an indication bit of the delay requirement of the uplink data that triggers the uplink wake-up signal.

[0148] In some embodiments, the configuration information of the triggering condition of the wake-up signal can implicitly indicate the latency requirement of the uplink data that triggers the uplink wake-up signal. For example, the latency requirement of the uplink data that triggers the uplink wake-up signal can be associated with at least one of the scrambling code sequence of the signal in which the configuration information of the triggering condition of the wake-up signal is located and the resource location.

[0149] 4) Measurement conditions for triggering the uplink wake-up signal.

[0150] In this embodiment, whether the uplink wake-up signal is triggered can also be associated with the measurement conditions (also known as measurement results / channel conditions) obtained by the terminal device measuring the channel. For example, when the channel conditions between the terminal device and the network device are good, the uplink wake-up signal can be triggered; when the channel conditions between the terminal device and the network device are poor, the uplink wake-up signal may not be triggered. Accordingly, the network device can indicate the measurement conditions for triggering the uplink wake-up signal to the terminal device through the configuration information of the uplink wake-up signal trigger conditions.

[0151] In some embodiments, the configuration information of the triggering condition of the wake-up signal can display an indication of the measurement conditions for triggering the uplink wake-up signal. For example, the configuration information of the triggering condition of the wake-up signal can carry an indication bit and / or parameter field of the measurement conditions for triggering the uplink wake-up signal.

[0152] In this embodiment of the application, the network device can indicate the conditions for triggering the uplink wake-up signal to the terminal device through wake-up configuration information, so that the terminal device can transmit the uplink wake-up signal when the above conditions are met, ensuring the accuracy and effectiveness of the uplink wake-up signal transmission, avoiding unnecessary wake-ups of the network device, and thus ensuring the energy-saving effect of the network device.

[0153] Based on the solutions shown in any one or more embodiments of the above-described embodiments of this application, in some embodiments, when the configuration information of the triggering condition of the uplink wake-up signal is used to indicate the latency requirement of the uplink data that triggers the uplink wake-up signal, the configuration information of the triggering condition of the uplink wake-up signal includes at least one of the following information:

[0154] 1) First delay threshold: The first delay threshold is used to compare with the delay requirements of the uplink data in the terminal device to determine whether to trigger the uplink wake-up signal.

[0155] In some embodiments, when the latency requirement of uplink data in the terminal device is not greater than or less than the first latency threshold mentioned above, it indicates that the uplink data in the terminal device needs to be transmitted in a timely manner. In this case, it is considered that the terminal device meets the triggering conditions of the uplink wake-up signal.

[0156] In some embodiments, when the latency requirement of uplink data in the terminal device is greater than the first latency threshold mentioned above, it indicates that the uplink data in the terminal device can be transmitted with an appropriate delay. In this case, it is considered that the terminal device does not meet the triggering conditions of the uplink wake-up signal.

[0157] 2) Second delay threshold: The second delay threshold is used to compare with the duration of the next time the network device enters the receiving state to determine whether to trigger the uplink wake-up signal.

[0158] In some embodiments, if the duration of the next time the network device enters the receiving state is not greater than or less than the second delay threshold mentioned above, it indicates that the network device is about to enter the receiving state. The uplink data in the terminal device can be delayed until the network device enters the receiving state again. In this case, it is considered that the terminal device does not meet the triggering conditions of the uplink wake-up signal.

[0159] In some embodiments, if the duration of the next time the network device enters the receiving state is greater than the second delay threshold mentioned above, it indicates that the network device still needs a long time to enter the receiving state, and the uplink data in the terminal device may not be delayed until the network device enters the receiving state again. In this case, it is considered that the terminal device meets the triggering conditions of the uplink wake-up signal.

[0160] In this embodiment of the application, the network device can indicate to the terminal device a first delay threshold that is compared with the delay requirement of the uplink data in the terminal device, and / or a second delay threshold that is compared with the duration of the next time the network device enters the receiving state, through wake-up configuration information, so that the terminal device can accurately determine whether to trigger the uplink wake-up signal, thereby ensuring the energy-saving effect of the network device as much as possible while ensuring transmission efficiency.

[0161] Based on the solutions shown in any one or more embodiments of the above-described embodiments of this application, in some embodiments, when the configuration information for the triggering condition of the uplink wake-up signal is used to indicate the measurement conditions for triggering the uplink wake-up signal, the configuration information for the triggering condition of the uplink wake-up signal includes at least one of the following:

[0162] 1) Downlink signal quality threshold: The downlink signal quality threshold is used to compare with the downlink signal quality measured by the terminal equipment to determine whether to trigger the uplink wake-up signal.

[0163] In some embodiments, the downlink signal quality threshold may include at least one of the following thresholds:

[0164] Reference Signal Receiving Power (RSRP) threshold, Received Signal Strength Indication (RSSI) threshold, Signal to Interference plus Noise Ratio (SINR) threshold, and Reference Signal Receiving Quality (RSRQ) threshold.

[0165] In some embodiments, if the signal quality measured most recently by the terminal device is not greater than or less than the aforementioned downlink signal quality threshold, it indicates that the channel conditions of the terminal device are poor. In this case, it can be determined that the terminal device does not meet the triggering conditions for the uplink wake-up signal.

[0166] In some embodiments, if the signal quality measured most recently by the terminal device is greater than the downlink signal quality threshold mentioned above, it indicates that the channel conditions of the terminal device are good. In this case, it can be determined that the terminal device does not meet the triggering conditions of the uplink wake-up signal.

[0167] 2) Downlink path loss threshold: The downlink path loss threshold is used to compare with the downlink path loss measured by the terminal equipment to determine whether to trigger the uplink wake-up signal.

[0168] The aforementioned downlink path loss can refer to the downlink path loss from the network device to the terminal device.

[0169] In some embodiments, if the downlink path loss measured most recently by the terminal device is not greater than or less than the aforementioned downlink path loss threshold, it indicates that the channel conditions of the terminal device are good. In this case, it can be determined that the terminal device meets the triggering conditions for the uplink wake-up signal.

[0170] In some embodiments, if the downlink path loss measured most recently by the terminal device is greater than the downlink path loss threshold, it indicates that the channel conditions of the terminal device are poor. In this case, it can be determined that the terminal device does not meet the triggering conditions of the uplink wake-up signal.

[0171] In this embodiment of the application, the network device can indicate downlink signal quality threshold and / or downlink path loss threshold to the terminal device through wake-up configuration information, so that the terminal device can compare the most recent measurement result with the downlink signal quality threshold and / or downlink path loss threshold to accurately determine whether to trigger the uplink wake-up signal, thereby ensuring the energy-saving effect of the network device as much as possible while ensuring transmission efficiency.

[0172] Step 820: Network devices enter power-saving mode.

[0173] In some embodiments, network devices may periodically enter or exit power-saving state according to the aforementioned wake-up cycle.

[0174] For example, please refer to Figure 9, which shows a schematic diagram of the wake-up cycle involved in the embodiments of this application. As shown in Figure 9, when a wake-up cycle arrives (corresponding to time T1 in Figure 9), the network device enters a power-saving state, shuts down the main transceiver and starts the low-power receiver, and listens for uplink wake-up signals through the low-power receiver; after a certain period of time (corresponding to time T2 in Figure 9), the network device exits the power-saving state, starts the main transceiver to communicate with the terminal device, for example, sending SSB, receiving random access messages sent by the terminal device, sending random access messages to the terminal device, establishing an RRC connection with the terminal device and transmitting data (such as sending downlink control signaling, receiving uplink control signaling, sending downlink data, receiving uplink data), etc.; after another certain period of time (corresponding to time T3 in Figure 9), the next wake-up cycle arrives, and the network device enters the power-saving state again.

[0175] Step 830: The terminal device sends an uplink wake-up signal to the network device when the network device is in power-saving mode, based on the wake-up configuration information; the uplink wake-up signal is a sequence-based signal.

[0176] In some embodiments, the terminal device can determine whether the network device is currently in a power-saving state based on the above wake-up cycle. For example, taking Figure 9 as an example, if the terminal device determines that the network device may be in a power-saving state during the time period between T0 and T1, then when uplink data arrives at the terminal device, the terminal device can send an uplink wake-up signal to the network device based on the wake-up configuration information.

[0177] In some embodiments, when uplink data arrives in the terminal device, the terminal device can determine the transmission resources and signal type of the uplink wake-up signal according to the transmission configuration information of the uplink wake-up signal in the wake-up configuration information, and send the uplink wake-up signal according to the transmission resources and signal type of the uplink wake-up signal.

[0178] In some embodiments, when uplink data arrives at the terminal device, the terminal device can determine whether it meets the triggering conditions for the uplink wake-up signal based on the configuration information of the triggering conditions for the uplink wake-up signal in the wake-up configuration information. If it is determined that the triggering conditions for the uplink wake-up signal are met, the uplink wake-up signal can be sent.

[0179] In some embodiments, when uplink data arrives at the terminal device, the terminal device can first determine whether it meets the triggering conditions of the uplink wake-up signal according to the configuration information of the triggering conditions of the uplink wake-up signal in the wake-up configuration information. If it is determined that the triggering conditions of the uplink wake-up signal are met, the terminal device can then determine the transmission resources and signal type of the uplink wake-up signal according to the transmission configuration information of the uplink wake-up signal in the wake-up configuration information, and send the uplink wake-up signal according to the transmission resources and signal type of the uplink wake-up signal.

[0180] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, the uplink wake-up signal is used to indicate at least one of the following information:

[0181] 1) Uplink data has arrived at the terminal device.

[0182] 2) Data type of upstream data.

[0183] In some embodiments, the aforementioned uplink wake-up signal may implicitly indicate the data type of the uplink data. For example, different uplink wake-up signal sequences, uplink wake-up signal modulation schemes, and / or transmission resources where the uplink wake-up signal is located may be associated with different data types of uplink data.

[0184] In some embodiments, the aforementioned uplink wake-up signal can explicitly indicate the data type of the uplink data. For example, the uplink wake-up signal can carry an indicator bit indicating the data type of the uplink data.

[0185] 3) The amount of data uploaded.

[0186] In some embodiments, the aforementioned uplink wake-up signal can implicitly indicate the amount of uplink data. For example, different uplink wake-up signal sequences, uplink wake-up signal modulation schemes, and / or transmission resources where the uplink wake-up signal is located can be associated with different ranges of uplink data amounts.

[0187] In some embodiments, the aforementioned uplink wake-up signal can explicitly indicate the amount of uplink data. For example, the uplink wake-up signal can carry an indicator bit for the amount of uplink data.

[0188] In this embodiment of the application, in addition to waking up the network device through the aforementioned uplink wake-up signal, the terminal device can also use the aforementioned uplink wake-up signal to indicate that uplink data has arrived in the terminal device, including information such as the data type and data volume. This enables the network device to accurately schedule uplink resources for the terminal device and receive uplink data, ensuring the efficiency of data transmission.

[0189] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, the data type of uplink data is associated with at least one of the following: the signal sequence of the uplink wake-up signal; the resource location where the uplink wake-up signal is located; and the logical channel where the uplink wake-up signal is located.

[0190] In this embodiment, when the terminal device sends the aforementioned uplink wake-up signal, it can select the signal sequence of the uplink wake-up signal, the resource location of the uplink wake-up signal, and / or the logical channel of the uplink wake-up signal according to the data type of the uplink data to be uploaded. When the network device receives the aforementioned uplink wake-up signal, it can determine the data type of the uplink data through the signal sequence of the uplink wake-up signal, the resource location of the uplink wake-up signal, and / or the logical channel of the uplink wake-up signal. This can reduce the data volume of the uplink wake-up signal, save channel resources, improve the transmission efficiency of the uplink wake-up signal, and improve the energy-saving effect of the network device.

[0191] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, the wireless communication method shown in the embodiments of this application may further include the following steps:

[0192] Step 840: After completing the uplink wake-up signal transmission, start the timer.

[0193] In this embodiment of the application, after the terminal device sends the aforementioned uplink wake-up signal, it can start a timer.

[0194] In some embodiments, the duration of the timer can be predetermined by a protocol or indicated by a network device. For example, the duration of the timer can be indicated by the network device through the wake-up configuration information; for example, the wake-up configuration information can carry an indication bit for the duration; or for example, the duration can be associated with the scrambling sequence of the wake-up configuration information, the resource location, etc.

[0195] In some embodiments, the timing duration of the timer is associated with at least one of the following: the data type of the uplink data, the logical channel, and the delay requirement.

[0196] Step 850: During the timer's running period, listen for uplink scheduling information.

[0197] In this embodiment of the application, after receiving the uplink wake-up signal, the network device can wake up the master transceiver and send uplink scheduling information to the terminal device. During the running period of the timer, the terminal device listens to the uplink scheduling information sent by the network device. For example, the uplink scheduling information may indicate the time-frequency resources used for transmitting uplink data. After listening to the uplink scheduling information, the terminal device can transmit the uplink data on the resources indicated by the uplink scheduling information.

[0198] In the solution shown in the embodiments of this application, after the uplink wake-up signal is sent, the terminal device can listen to the uplink scheduling information within the timer's duration, without having to continuously listen to the uplink scheduling information, thereby saving the terminal device's energy consumption.

[0199] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, the wireless communication method shown in the embodiments of this application may further include the following steps:

[0200] Step 860: When the network device is in power-saving mode, uplink data arrives at the terminal device, and the triggering conditions for the uplink wake-up signal are not met, the uplink data is sent when the network device enters the transmit / receive state again.

[0201] In some embodiments, if uplink data arrives at the terminal device while the network device is in power-saving mode and the triggering conditions for the uplink wake-up signal are not met, it indicates that the uplink data can be transmitted with an appropriate delay. In this case, the terminal device can send uplink data when the network device enters the transmit / receive state again.

[0202] Correspondingly, when the network device is in power-saving mode, uplink data arrives at the terminal device, and the triggering conditions for the uplink wake-up signal are not met, the network device can receive the uplink data sent by the terminal device when it enters the transmit / receive state again.

[0203] For example, the terminal device can use the aforementioned wake-up cycle to determine the time period during which the network device enters the transmit / receive state each time, and send the aforementioned uplink data the next time the network device enters the transmit / receive state.

[0204] In the solution shown in the embodiments of this application, when the network device is in energy-saving mode and uplink data arrives at the terminal device but the triggering conditions of the uplink wake-up signal are not met, the terminal device can delay the uplink data until the network device enters the next transmit / receive state before sending it, thereby avoiding unnecessary wake-up of the network device and ensuring the energy-saving effect of the network device.

[0205] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, please refer to FIG10, which shows a schematic diagram of a network device wake-up according to an embodiment of this application.

[0206] As shown in part (a) of Figure 10, when the network device is in the transmit / receive state, it can send wake-up configuration information 1010 to the terminal device. The wake-up configuration information 1010 is used to configure at least one of the following: the wake-up period of the network device, the transmission method of the uplink wake-up signal (such as transmission resources, signal type, etc.), and the triggering condition of the uplink wake-up signal.

[0207] As shown in part (b) of Figure 10, after the network device enters the power-saving state, the terminal device receives uplink data 1020 that needs to be sent. At this time, according to the wake-up configuration information 1010 mentioned above, if the terminal device determines that the triggering conditions of the uplink wake-up signal are met, it can send an uplink wake-up signal 1030 to the network device. The network device can send uplink scheduling information 1040 to the terminal device, and the terminal device sends uplink data 1020 to the network device according to the uplink scheduling information 1040.

[0208] As shown in part (c) of Figure 10, according to the wake-up configuration information 1010, if the terminal device determines that the triggering conditions of the uplink wake-up signal are not met, it can wait for the network device to enter the transmit / receive state again to send uplink data 1020.

[0209] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, the wireless communication method shown in the embodiments of this application may further include the following steps:

[0210] Step 870: When the network device is in power-saving mode, uplink data arrives at the terminal device, and the triggering conditions for the uplink wake-up signal are not met, execute the random access procedure.

[0211] In some embodiments, if uplink data arrives at the terminal device while the network device is in power-saving mode and the triggering conditions for the uplink wake-up signal are not met, the terminal device is not allowed to wake up the network device. In this case, if the terminal device needs to transmit uplink data immediately, it can initiate a random access procedure to trigger the reconstruction procedure of the connection between the terminal device and the network, thereby reconstructing the connection between the terminal device and the network device as soon as possible and sending the aforementioned uplink data.

[0212] Correspondingly, when the network device is in energy-saving mode, uplink data arrives at the terminal device, and the triggering conditions for the uplink wake-up signal are not met, the network device can receive the random access message sent by the terminal device and execute the connection reconstruction process according to the random access message.

[0213] In the solution shown in the embodiments of this application, when the network device is in energy-saving mode, and uplink data arrives at the terminal device but the triggering conditions of the uplink wake-up signal are not met, the terminal device can trigger connection reconstruction through a random access procedure to ensure that the uplink data can be transmitted in a timely manner and improve the data transmission effect of the terminal device.

[0214] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, please refer to FIG11, which shows a schematic diagram of a network device wake-up according to an embodiment of this application.

[0215] As shown in part (a) of Figure 11, when the network device is in the transmit / receive state, it can send wake-up configuration information 1110 to the terminal device. The wake-up configuration information 1110 is used to configure at least one of the following: the wake-up period of the network device, the transmission method of the uplink wake-up signal (such as transmission resources, signal type, etc.), and the triggering condition of the uplink wake-up signal.

[0216] As shown in part (b) of Figure 11, after the network device enters the power-saving state, the terminal device receives uplink data 1120 that needs to be sent. At this time, according to the wake-up configuration information 1110 mentioned above, if the terminal device determines that the triggering conditions of the uplink wake-up signal are met, it can send an uplink wake-up signal 1130 to the network device. The network device can send uplink scheduling information 1140 to the terminal device, and the terminal device sends uplink data 1120 to the network device according to the uplink scheduling information 1140.

[0217] As shown in part (c) of Figure 11, according to the wake-up configuration information 1110 above, if the terminal device determines that the triggering conditions of the uplink wake-up signal are not met, it can initiate a random access procedure to trigger connection reconstruction. After the connection reconstruction is completed, the terminal device can send uplink data 1120.

[0218] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, the wireless communication method shown in the embodiments of this application may further include the following steps:

[0219] Step 880: When the network device is in power-saving mode, uplink data arrives at the terminal device, and the triggering conditions of the uplink wake-up signal are not met, and when the terminal device has candidate cell configuration, lower the handover threshold of Conditional Handover (CHO).

[0220] In some embodiments, if uplink data arrives at the terminal device while the network device is in power-saving mode, and the triggering conditions for the uplink wake-up signal are not met, the terminal device is not allowed to wake up the network device. In this case, if the terminal device needs to transmit uplink data as soon as possible, the handover threshold of the conditional handover CHO (such as the RSRP threshold for triggering cell handover, etc.) can be lowered so that the terminal device can switch to an adjacent cell as soon as possible, for example, to the cell corresponding to an adjacent terminal device that has not entered power-saving mode. After the cell handover is completed, the terminal device can send the aforementioned uplink data.

[0221] In the solution shown in the embodiments of this application, when the network device is in power-saving mode, and uplink data arrives at the terminal device but the triggering conditions of the uplink wake-up signal are not met, the terminal device can trigger cell handover as soon as possible by lowering the handover threshold of the conditional handover CHO, so as to ensure that the uplink data can be transmitted in a timely manner and improve the data transmission effect of the terminal device.

[0222] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, in some embodiments, please refer to FIG12, which shows a schematic diagram of a network device wake-up according to an embodiment of this application.

[0223] As shown in part (a) of Figure 12, when the network device is in the transmit / receive state, it can send wake-up configuration information 1210 to the terminal device. The wake-up configuration information 1210 is used to configure at least one of the following: the wake-up period of the network device, the transmission mode of the uplink wake-up signal (such as transmission resources, signal type, etc.), and the triggering condition of the uplink wake-up signal.

[0224] As shown in part (b) of Figure 12, after the network device enters the power-saving state, the terminal device receives uplink data 1220 that needs to be sent. At this time, according to the wake-up configuration information 1210 mentioned above, if the terminal device determines that the triggering conditions of the uplink wake-up signal are met, it can send an uplink wake-up signal 1230 to the network device. The network device can send uplink scheduling information 1240 to the terminal device, and the terminal device sends uplink data 1220 to the network device according to the uplink scheduling information 1240.

[0225] As shown in part (c) of Figure 12, according to the wake-up configuration information 1210, if the terminal device determines that the triggering conditions of the uplink wake-up signal are not met, it can lower the handover threshold of the conditional handover (CHO). If the handover is triggered after lowering the CHO handover threshold, the terminal device can initiate the handover. After the handover is completed, the terminal device can send uplink data 1220.

[0226] Based on the solutions shown in any one or more embodiments of the above embodiments of this application, the UE determines whether to trigger the transmission of an uplink wake-up signal according to the characteristics of the arriving service. This wake-up signal is used to notify the network whether to schedule uplink data from the terminal, for example:

[0227] S1, the UE receives network configuration information, which instructs the UE to include the following:

[0228] 1) Indicates the wake-up cycle of the terminal network, that is, during which time periods the network is in the sending / receiving state and during which time periods the network is in the power-saving state, for example:

[0229] ① When the network is in the transmit / receive state, it can transmit downlink data and receive uplink data;

[0230] ② When the network is in power-saving mode, the network's low-power receiver is in working mode, which means that the network can receive wake-up signals from the terminal.

[0231] 2) Instruct the terminal on the corresponding wake-up signal configuration, that is, on which uplink resources the UE can send uplink wake-up signals. Specifically, the following information can be indicated:

[0232] ①When the network is in power-saving mode, the UE can send uplink wake-up signals using time and frequency resources;

[0233] ② The type of wake-up signal, such as a wake-up signal type similar to LP-WUS, or a wake-up signal type based on OOK or OFDM superimposed with OOK, which is a sequence signal.

[0234] 3) Indicate which service types the UE can use to trigger the wake-up signal, for example:

[0235] ① You can configure one or more logical channels to trigger the sending of wake-up signals;

[0236] ② It can also be configured to trigger the sending of a wake-up signal when the UE meets certain characteristic measurement conditions; the satisfaction of the measurement conditions means that the terminal is in a suitable coverage area, so that the network's low-power receiver can correctly receive the uplink wake-up signal sent by the UE.

[0237] S2, the UE performs downlink reception and uplink transmission based on network configuration information; when the UE is in the network's non-wake-up cycle, the UE decides whether to trigger the transmission of an uplink wake-up signal according to the configured conditions, specifically:

[0238] 1) The UE has new uplink data arriving. This uplink data is either emergency data or latency-sensitive data that meets the configuration. Specifically, the network configures the logical channel where this data is located as a logical channel that can trigger an uplink wake-up signal.

[0239] 2) The UE can also determine that the uplink wake-up signal triggering conditions can be met based on the uplink data latency requirement. If the uplink data latency requirement is less than a certain configured latency threshold, and / or the time interval between the current time and the next time the network enters the wake-up cycle is greater than a time threshold.

[0240] 3) The UE measures the downlink channel quality. For example, the UE can determine whether the uplink wake-up signal is within the network's reception range based on the downlink path loss and a pre-configured path loss threshold. If the downlink path loss measurement meets the threshold, the uplink wake-up signal is within the reception range of the network's low-power receiver.

[0241] 4) The UE determines whether one or more of the above conditions are met. If they are met, then:

[0242] ① Based on network configuration, trigger the sending of uplink wake-up signals;

[0243] ② This uplink wake-up signal is used to indicate to the network that the UE has new data that matches the configuration.

[0244] ③ The uplink wake-up signal can also indicate the type of uplink data, such as the sequence of different uplink wake-up signals, and the correspondence between time-frequency resource locations and logical channels;

[0245] ④After the UE sends the uplink wake-up signal, it starts a timer to receive uplink scheduling information. During the timer period, it listens for uplink scheduling.

[0246] 5) If the UE determines that the uplink wake-up signal triggering condition is not met, then:

[0247] ①The UE waits for the next network wake-up cycle to send uplink data;

[0248] ②The UE can trigger a random access procedure to initiate a reconstruction procedure during the network non-wake-up period based on network configuration. This random access procedure can indicate to the UE that new data has arrived during the network non-wake-up period.

[0249] Alternatively, when the UE has candidate cells configured, the UE can lower the threshold for CHO (Conditional Handover) execution conditions to allow the UE to switch to other cells as much as possible. For example, if the base station only has LR enabled, it may not be able to receive preamble. When there is a long interval between Cell-DTX / DRX off, the UE can try to initiate random access to other cells (cells that are in active time or have not entered Cell DTX / DRX mode).

[0250] The above embodiments of this application disclose a method for a terminal to send an uplink wake-up signal. Introducing an uplink wake-up signal allows the UE to send one during the network's non-wake-up period. This wake-up signal indicates that an urgent or latency-sensitive service has arrived during the network's non-wake-up period. Therefore, the network can decide whether to allocate uplink resources during this non-wake-up period to ensure the UE can promptly send latency-sensitive or urgent services, thereby meeting service requirements.
