For ease of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is generally multiple, and one or more terminal devices 10 may be distributed in each cell managed by an access network device 20.

Access network equipment 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different wireless access technologies, the names of devices that provide access network equipment functions may vary. For example, in 5G NR systems, they are referred to as gNodeBs or gNBs. As communication technologies evolve, the term "access network equipment" may change. For ease of description, in the embodiments of this application, the aforementioned devices that provide wireless communication capabilities for terminal device 10 are collectively referred to as access network equipment.

[0048] Before introducing the technical solutions of this application, we first introduce and explain some of the background technologies involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0049] 1. Network Energy Saving Background

[0050] Network energy conservation is crucial for environmental sustainability, reducing environmental impact (e.g., greenhouse gas emissions), and saving operating costs. As 5G becomes increasingly widespread across various industries and geographic regions, it will require very high data rates to handle more advanced services and applications (such as XR (Extended Reality)). This will require denser network deployments, using more antennas, greater bandwidth, and more frequency bands. Given the environmental impact of 5G, new, controlled solutions are needed to enhance network energy conservation.

[0051] Energy consumption has become a key component of operators' operational expenditures (OPEX). According to a report by the GSMA (Global System for Mobile communications Association), energy costs for mobile networks account for approximately 23% of total OPEX. Most of this energy consumption comes from the radio access network, more specifically, the active antenna unit (AAU), with data centers and fiber optic transmission contributing to a smaller share. The power consumption of a single radio access can be divided into two parts: the dynamic part includes only the power consumption when data is being sent or received; the static part includes the power consumption required to maintain the necessary operations of the radio access equipment at all times, including when no data is being sent or received.

[0052] Therefore, based on the above objectives, it is necessary to research and develop network energy consumption models, KPIs (Key Performance Indicators), and evaluation methods on the network device side to determine and study network energy-saving technologies in the target deployment scenario. Among them, the power consumption model on the terminal device side that has been defined can be used as a reference. This research should focus on how to achieve more efficient dynamic operation and / or semi-static operation, and consider one or more network energy-saving technologies applied to the time domain, frequency domain, spatial domain, and power domain, combined with potential terminal device feedback support, potential terminal device auxiliary information, and information exchange or coordination between network interfaces to achieve more fine-grained data transmission and / or reception adaptation.

[0053] It is worth noting that this study not only evaluates potential network energy savings but also assesses and balances the impact on network and user performance by observing key performance indicators (KPIs) such as spectrum efficiency, capacity, user perceived throughput (UPT), latency, UE power consumption, complexity, handover performance, call drop rate, initial access performance, and SLA security-related KPIs. This study should avoid significantly impacting these KPIs.

[0054] 2. Network energy-saving technology

[0055] In a network energy-saving system, network devices can enter sleep mode (or energy-saving mode) when the traffic load is light or no traffic load in order to save energy. Table 1 shows a schematic diagram of a network device energy consumption model.

[0056] Table 1 Network equipment energy consumption model reference

[0057]

[0058]

[0059] However, when a network device enters sleep mode, if a terminal device receives incoming traffic, it cannot communicate with the network device in a timely manner. Consequently, the terminal device's traffic may be unable to transmit for an extended period. To address this issue, the network device can configure a gNB wakeup signal (gNB-WUS) resource for the terminal device. This resource allows the network device to detect wakeup requests from the terminal device even when the device is in or enters sleep mode. When traffic arrives from the terminal device, the gNB-WUS resource can be used to send a wakeup request to the network device, allowing the network device to be informed of the terminal device's transmission requirements.

[0060] In this application, the "sleep mode" involved is also referred to as "energy-saving mode", "energy-saving state", "sleep state", "sleep mode state", "sleep energy-saving mode" or "sleep energy-saving state" and other names, but those skilled in the art can understand its meaning.

[0061] Please refer to Figure 2, which shows a flowchart of a wireless communication method provided by an embodiment of the present application. The method can be performed by a terminal device. The method may include at least one of the following steps:

[0062] Step 210: The terminal device monitors and / or receives a first downlink channel or signal within a first time period.

[0063] In some embodiments, the terminal device determines a first time period and monitors and / or receives a first downlink channel or signal during the first time period. For details on how the terminal device determines the first time period, please refer to the description in the following embodiments.

[0064] In some embodiments, the first downlink channel or signal includes at least one of the following: PDCCH (Physical Downlink Control Channel), SSB (Synchronization Signal / PBCH block), CSI-RS (Channel State Information Reference Signal), downlink PRS (Positioning Reference Signal), TRS (Tracking Reference Signal), UE-WUS (UE wakeup signal), and PDSCH (Physical Downlink Shared Channel).

[0065] In some embodiments, the UE-WUS includes a signal sent by a network device to a terminal device to wake up the terminal device. For example, when the terminal device detects the UE-WUS on a UE-WUS resource, it may detect the PDCCH on a PDCCH search space associated with the UE-WUS.

[0066] In some embodiments, the above-mentioned PDCCH includes at least one of the following: a terminal device-specific PDCCH and a public PDCCH.

[0067] In some embodiments, the PDCCH includes: a PDCCH carrying HARQ-ACK (Hybrid Automatic Repeat request-Acknowledgement) information. Optionally, the HARQ-ACK information is ACK (Acknowledgement) information.

[0068] In some embodiments, the PDSCH includes: a PDSCH carrying HARQ-ACK information. For example, MACCE (MAC Control Element, Media Access Layer Control Element) information carried in the PDSCH is used to indicate HARQ-ACK information. Optionally, the HARQ-ACK information is ACK information.

[0069] Optionally, the above-mentioned HARQ-ACK information is HARQ feedback information for the first uplink channel or signal sent by the terminal device.

[0070] In some embodiments, the first downlink channel or signal includes a PDCCH, and the terminal device monitors and / or receives the first downlink channel or signal within a first time period, including: the terminal device monitors a PDCCH candidate within the first time period.

[0071] In some embodiments, the method further includes: the terminal device sending a first uplink channel or signal within a first time period. Optionally, after the terminal device sends the first uplink channel or signal within the first time period, the terminal device monitors and / or receives the first downlink channel or signal within the first time period.

[0072] In some embodiments, the first uplink channel or signal includes at least one of the following: PUCCH (Physical Uplink Control Channel), SRS (Sounding Reference Signal) (for example, SRS for MIMO (Multiple Input Multiple Output) measurement and / or SRS for uplink positioning), PUSCH (Physical Uplink Shared Channel), and PRACH (Physical Random Access Channel).

[0073] In some embodiments, the first uplink channel or signal includes: a network device wake-up signal (also known as a base station wake-up signal, gNB-WUS).

[0074] Optionally, the gNB-WUS includes a signal sent by the terminal device to the network device to wake up the network device. For example, the terminal device sends the gNB-WUS to the network device using uplink resources configured by the network device for the terminal device to send the gNB-WUS. Thereafter, the terminal device monitors and / or receives a first downlink channel or signal within a first time period.

[0075] In some embodiments, the PUSCH includes at least one of the following: a pre-configured CG-PUSCH (Configured grant-PUSCH, configured grant-PUSCH), a PUSCH scheduled by DCI (Downlink Control Information, downlink control information).

[0076] In some embodiments, the terminal device monitoring and / or receiving a first downlink channel or signal within a first time period includes: the terminal device monitoring and / or receiving a first downlink channel or signal on a first cell within the first time period; or the terminal device monitoring and / or receiving a first downlink channel or signal corresponding to the first cell within the first time period. The first cell is a serving cell of the terminal device. Optionally, the first cell includes one cell, or the first cell includes multiple cells.

[0077] The technical solution provided by the embodiment of the present application is that, for a network device that can be configured in sleep mode, the terminal device can determine a suitable time period and monitor and / or receive the downlink channel or signal of the network device during this time period, thereby avoiding the disadvantage that the network device cannot serve the terminal device for a long time in sleep mode, resulting in too large a communication transmission delay of the terminal device, thereby improving the transmission performance between the terminal device and the network device.

[0078] The determination of the first time period includes at least one of the following situations.

[0079] Case 1:

[0080] In some embodiments, the first time period is determined according to the time domain position of the first uplink resource.

[0081] In some embodiments, the starting position of the first time period is determined according to the time domain position of the first uplink resource.

[0082] In some embodiments, the first uplink resource includes a network device wake-up signal resource used by the terminal device to transmit a network device wake-up signal. For example, the first uplink resource includes an uplink resource configured by the network device for the terminal device to transmit a gNB-WUS.

[0083] In some embodiments, before the terminal device monitors and / or receives the first downlink channel or signal within the first time period, or before the terminal device determines the first time period, the method further includes: the terminal device sending the first uplink channel or signal via the first uplink resource. For example, the terminal device sends the first uplink channel or signal to the network device via the first uplink resource.

[0084] In some embodiments, the first uplink channel or signal includes a network device wake-up signal. For example, the terminal device transmits the gNB-WUS to the network device using uplink resources configured by the network device for transmitting the gNB-WUS.

[0085] In some embodiments, after the terminal device sends the first uplink channel or signal through the first uplink resource, the method further includes: the terminal device determines the starting position of the first time period according to the time domain position of the first uplink resource.

[0086] Exemplarily, the starting position of the first time period is the ending position of the first uplink resource.

[0087] Exemplarily, the starting position of the first time period is the ending position of the time unit where the first uplink resource is located.

[0088] Exemplarily, there is a first offset value between the start position of the first time period and the end position of the first uplink resource. For example, the start position of the first time period is the time domain position after the end position of the first uplink resource is offset backward by the first offset value.

[0089] Exemplarily, there is a first offset value between the start position of the first time period and the end position of the time unit where the first uplink resource is located. For example, the start position of the first time period is the time domain position after the end position of the time unit where the first uplink resource is located is offset backward by the first offset value.

[0090] Exemplarily, the starting position of the first time period is the starting position of the first downlink resource after the first uplink resource. For example, the starting position of the first time period is the starting position of the first downlink resource after the first uplink resource.

[0091] Exemplarily, the starting position of the first time period is the starting position of the time unit where the first downlink resource after the first uplink resource is located. For example, the starting position of the first time period is the starting position of the time unit where the first downlink resource after the first uplink resource is located.

[0092] Exemplarily, the starting position of the first time period is the starting position of the first downlink resource after the first uplink resource and after the first offset value. For example, the starting position of the first time period is the starting position of the first downlink resource after the first uplink resource is offset backward by the first offset value.

[0093] Exemplarily, the starting position of the first time period is the starting position of the time unit where the first downlink resource is located after the first uplink resource and after the first offset value. For example, the starting position of the first time period is the starting position of the time unit where the first downlink resource is located after the first uplink resource is offset backward by the first offset value.

[0094] In some embodiments, the first downlink resource includes resources corresponding to the PDCCH search space and / or terminal device wake-up signal resources (such as UE-WUS resources). Optionally, the terminal device wake-up signal resource includes at least one of the following: a terminal device wake-up signal resource dedicated to the terminal device, and a public terminal device wake-up signal resource.

[0095] As an example but not limitation, the first downlink resource is a resource corresponding to the first PDCCH search space after the first uplink resource, or the first downlink resource is the first UE-WUS resource after the first uplink resource.

[0096] In addition, in an embodiment of the present application, a time unit includes at least one of a time slot, a subframe, a symbol, or a sub-time slot. A sub-time slot includes an integer number of symbols. Optionally, the symbol includes an OFDM (Orthogonal Frequency Division Multiplexing) symbol determined based on a subcarrier spacing, where the subcarrier spacing may be predefined or configured by a network device.

[0097] In some embodiments, the first offset value is predefined. For example, the first offset value is predefined by a protocol, or the first offset value is determined based on a parameter predefined by the protocol. For another example, the first offset value is determined based on a processing time of the network device.

[0098] In some embodiments, the first offset value is configured by the network device, or the first offset value is determined based on a configuration parameter of the network device.

[0099] In some embodiments, the first offset value is a positive number, or in other words, the first offset value is a positive offset value.

[0100] In some embodiments, the first offset value may be 0.

[0101] In some embodiments, the first uplink resource is associated with a sleep mode of the network device. For example, the first uplink resource includes a gNB-WUS resource corresponding to the sleep mode of the network device.

[0102] In some embodiments, the first downlink resource is a downlink resource in a third time period corresponding to the sleep mode of the network device.

[0103] In some embodiments, the third time period includes: a time period during which the network device is in sleep mode. Optionally, the time period during which the network device is in sleep mode includes: a time period corresponding to the network device's sleep period after entering sleep mode. Optionally, the time period during which the network device is in sleep mode includes: a time period corresponding to the network device's transition time to enter sleep mode, a time period corresponding to the network device's transition time to exit sleep mode, and a time period corresponding to the network device's sleep period after entering sleep mode.

[0104] In some embodiments, the third time period includes: a time period corresponding to a transition time when the network device is in sleep mode. Optionally, the time period corresponding to a transition time when the network device is in sleep mode includes: a time period corresponding to a transition time when the network device enters sleep mode, and / or a time period corresponding to a transition time when the network device leaves sleep mode.

[0105] For scenario 1, determining a first time period for monitoring and / or receiving the first downlink channel or signal, or determining the starting position of the first time period, is implemented based on the time domain location of the first uplink resource. For example, for a network device in sleep mode, if the terminal device is configured with a network device wake-up signal resource (such as a gNB-WUS resource), the terminal device can determine the first time period for monitoring and / or receiving the first downlink channel or signal, or determine the starting position of the first time period, based on the time domain location of the network device wake-up signal resource.

[0106] Exemplarily, the terminal device can use gNB-WUS resources to send a gNB-WUS signal to the network device. Within a first time period after sending the gNB-WUS signal, the terminal device monitors and / or receives a first downlink channel or signal, thereby waking up the network device when the terminal device has a transmission requirement. After being awakened, the network device provides services to the terminal device, thereby avoiding the disadvantage that the network device cannot serve the terminal device for a long time in sleep mode, resulting in a large communication transmission delay of the terminal device, and improving the transmission performance between the terminal device and the network device.

[0107] In some embodiments, the time domain resources of the first time period are determined based on the time domain position of the first uplink resource. For example, the starting position and ending position of the first time period are determined based on the time domain position of the first uplink resource. Based on the starting position and ending position of the first time period, the position of the first time period in the time domain can be known. Alternatively, the starting position and duration of the first time period are determined based on the time domain position of the first uplink resource. Based on the starting position and duration of the first time period, the position of the first time period in the time domain can also be known.

[0108] Case 2:

[0109] In some embodiments, the first time period is determined according to the time domain position of the first downlink resource.

[0110] In some embodiments, the starting position of the first time period is determined according to the time domain position of the first downlink resource.

[0111] In some embodiments, the first downlink resource is a downlink resource in a third time period corresponding to the sleep mode of the network device.

[0112] For example, the first downlink resource is the first downlink resource in the third time period corresponding to the sleep mode of the network device.

[0113] In some embodiments, the third time period includes: a time period during which the network device is in sleep mode. Optionally, the time period during which the network device is in sleep mode includes: a time period corresponding to the network device's sleep period after entering sleep mode. Optionally, the time period during which the network device is in sleep mode includes: a time period corresponding to the network device's transition time to enter sleep mode, a time period corresponding to the network device's transition time to exit sleep mode, and a time period corresponding to the network device's sleep period after entering sleep mode.

[0114] In some embodiments, the third time period includes: a time period corresponding to a transition time when the network device is in sleep mode. Optionally, the time period corresponding to a transition time when the network device is in sleep mode includes: a time period corresponding to a transition time when the network device enters sleep mode, and / or a time period corresponding to a transition time when the network device leaves sleep mode.

[0115] In some embodiments, the starting position of the first time period is determined based on the time domain position of the first downlink resource within the time period when the network device is in sleep mode; or, the starting position of the first time period is determined based on the time domain position of the first downlink resource within the time period corresponding to the transition time when the network device is in sleep mode; or, the starting position of the first time period is determined based on the time domain position of the first downlink resource within the time period corresponding to the transition time when the network device enters sleep mode.

[0116] For example, the first downlink resource is the first downlink resource in the time period when the network device is in the sleep mode; or, the first downlink resource is the first downlink resource in the time period corresponding to the transition time when the network device is in the sleep mode.

[0117] In some embodiments, before the terminal device monitors and / or receives the first downlink channel or signal within the first time period, the method further includes: the terminal device determining a starting position of the first time period. For example, the terminal device determines the starting position of the first time period based on a starting position of the first downlink resource.

[0118] Exemplarily, the starting position of the first time period is the starting position of the first downlink resource.

[0119] Exemplarily, the starting position of the first time period is the starting position of the time unit where the first downlink resource is located.

[0120] Exemplarily, the starting position of the first time period is the starting position of the first downlink resource after the starting position of the third time period is shifted by the second offset value. For example, the starting position of the first time period is the starting position of the first downlink resource after the starting position of the third time period is shifted backward by the second offset value.

[0121] Exemplarily, the starting position of the first time period is the starting position of the time unit where the first downlink resource is located after the starting position of the third time period is shifted by the second offset value. For example, the starting position of the first time period is the starting position of the time unit where the first downlink resource is located after the starting position of the third time period is shifted backward by the second offset value.

[0122] In some embodiments, the second offset value is predefined. For example, the second offset value is predefined by a protocol, or the second offset value is determined based on a parameter predefined by the protocol. For another example, the second offset value is determined based on a processing time of the network device.

[0123] In some embodiments, the second offset value is configured by the network device, or the second offset value is determined based on a configuration parameter of the network device.

[0124] In some embodiments, the second offset value is a positive number, or in other words, the second offset value is a positive offset value.

[0125] In some embodiments, the second offset value may be 0.

[0126] In some embodiments, the first downlink resource includes resources corresponding to the PDCCH search space and / or terminal device wake-up signal resources (such as UE-WUS resources). Optionally, the terminal device wake-up signal resource includes at least one of the following: a terminal device wake-up signal resource dedicated to the terminal device, and a public terminal device wake-up signal resource.

[0127] In case 2, the first time period for monitoring and / or receiving the first downlink channel or signal, or the starting position of the first time period, is determined based on the time domain position of the first downlink resource. This ensures that the terminal device successfully receives the first downlink channel or signal sent by the network device using the first downlink resource, thereby improving the success rate and reliability of downlink reception.

[0128] For example, for a network device with a sleep mode, the first downlink resource may include the downlink resource in the third time period corresponding to the sleep mode of the network device, so that the terminal device can receive the downlink channel or signal sent by the network device after waking up from the sleep mode as much as possible.

[0129] In some embodiments, the time domain resources of the first time period are determined based on the time domain position of the first downlink resource. For example, the starting position and ending position of the first time period are determined based on the time domain position of the first downlink resource. Based on the starting position and ending position of the first time period, the position occupied by the first time period in the time domain can be known. Alternatively, the starting position and duration of the first time period are determined based on the time domain position of the first downlink resource. Based on the starting position and duration of the first time period, the position occupied by the first time period in the time domain can also be known.

[0130] Case 3:

[0131] In some embodiments, the first time period is determined according to a third time period corresponding to a sleep mode of the network device.

[0132] In some embodiments, the third time period includes: a time period during which the network device is in sleep mode. Optionally, the time period during which the network device is in sleep mode includes: a time period corresponding to the network device's sleep period after entering sleep mode. Optionally, the time period during which the network device is in sleep mode includes: a time period corresponding to the network device's transition time to enter sleep mode, a time period corresponding to the network device's transition time to exit sleep mode, and a time period corresponding to the network device's sleep period after entering sleep mode.

[0133] In some embodiments, the third time period includes: a time period corresponding to a transition time when the network device is in sleep mode. Optionally, the time period corresponding to a transition time when the network device is in sleep mode includes: a time period corresponding to a transition time when the network device enters sleep mode, and / or a time period corresponding to a transition time when the network device leaves sleep mode.

[0134] In some embodiments, the starting position of the first time period is the starting position of the third time period; or, there is a second offset value between the starting position of the first time period and the starting position of the third time period.

[0135] For example, the third time period includes the time period corresponding to the transition time of the network device entering sleep mode; the starting position of the first time period is the starting position of the time period corresponding to the transition time of the network device entering sleep mode; or, there is a second offset value between the starting position of the first time period and the starting position of the time period corresponding to the transition time of the network device entering sleep mode.

[0136] In some embodiments, before the terminal device monitors and / or receives the first downlink channel or signal within the first time period, the method further includes: the terminal device determines the starting position of the first time period. For example, the terminal device determines the starting position of the first time period based on the third time period corresponding to the sleep mode of the network device. For example, the terminal device determines the starting position of the third time period as the starting position of the first time period. Alternatively, the terminal device shifts the starting position of the third time period backward by the time domain position of the second offset value, and determines it as the starting position of the first time period.

[0137] In some embodiments, the second offset value is predefined. For example, the second offset value is predefined by a protocol, or the second offset value is determined based on a parameter predefined by the protocol. For another example, the second offset value is determined based on a processing time of the network device.

[0138] In some embodiments, the second offset value is configured by the network device, or the second offset value is determined based on a configuration parameter of the network device.

[0139] In some embodiments, the second offset value is a positive number, or in other words, the second offset value is a positive offset value.

[0140] In some embodiments, the second offset value may be 0.

[0141] In case 3, a first time period for monitoring and / or receiving the first downlink channel or signal, or a starting position of the first time period, is determined based on a third time period corresponding to the sleep mode of the network device. Thus, for a network device in sleep mode, the terminal device can, as far as possible, receive downlink channels or signals sent by the network device after waking from sleep mode.

[0142] For the third time period mentioned in at least one of the above scenarios 1, 2, and 3, the length of the third time period is determined based on at least one of: configuration parameters of the network device, communication transmission requirements of the network device, and communication transmission requirements of the terminal device. For example, the network device preconfigures the length of the third time period, and when the network device or the terminal device has communication transmission requirements, the length of the third time period can be extended or shortened based on the communication transmission requirements.

[0143] In some embodiments, the communication transmission requirements of the network device include at least one of the following: downlink service transmission of the network device to at least one terminal device, uplink service transmission of the network device to at least one terminal device, paging message transmission of the network device, system message transmission of the network device, SSB transmission of the network device, downlink reference signal transmission of the network device, PRACH detection of the network device, and uplink reference signal transmission of the network device.

[0144] In some embodiments, the communication transmission requirements of the terminal device include at least one of the following: downlink service transmission of the terminal device, uplink service transmission of the terminal device, paging message transmission of the terminal device, system message transmission requested by the terminal device, SSB transmission requested by the terminal device, downlink reference signal transmission of the terminal device, PRACH transmission of the terminal device, and uplink reference signal transmission of the terminal device.

[0145] For the first time period mentioned in at least one of the above cases 1, 2 and 3, the length of the first time period may be determined as follows.

[0146] In some embodiments, the length of the first time period is determined based on the length of the first timer, wherein the start or restart moment of the first timer is the moment corresponding to the starting position of the first time period. Optionally, the length of the above-mentioned first timer and / or the first time period can be configured by the network device. Optionally, the length of the first timer is configured through at least one of a system message, RRC signaling, and MACCE. As an example and not a limitation, the terminal device is configured with the first timer and / or the length of the first timer. After the terminal device sends a gNB-WUS to the network device on the first uplink resource, the terminal device starts the first timer from the starting position of the first downlink resource after the first uplink resource, and monitors and / or receives the first downlink channel or signal during the running time of the first timer, wherein the running time of the first timer is the length of the first timer.

[0147] In some embodiments, the length of the first time period is determined based on the length of the first window, wherein the starting position of the first window is the starting position of the first time period. Optionally, the above-mentioned first window and / or the length of the first window can be configured by the network device. Optionally, the length of the first window is configured through at least one of a system message, RRC signaling, and MACCE. As an example and not a limitation, the terminal device is configured with the first window and / or the length of the first window. After the terminal device sends the gNB-WUS to the network device on the first uplink resource, the terminal device starts the first window from the starting position of the first downlink resource after the first uplink resource, and monitors and / or receives the first downlink channel or signal within the length of the first window.

[0148] In some embodiments, the length of the first time period is determined based on a configuration parameter of the network device. For example, the configuration parameter sent by the network device to the terminal device may explicitly or implicitly indicate the length of the first time period. Optionally, the length of the first time period is configured via at least one of a system message, RRC signaling, and a MACCE. By way of example and not limitation, the network device configures, for the terminal device, the length of a third time period corresponding to the network device entering the first sleep mode, and the length of the first time period is determined based on the length of the third time period.

[0149] In some embodiments, the length of the first time period is predefined or determined based on predefined parameters.

[0150] In some embodiments, for at least one of the above-mentioned cases 1, 2 and 3, the method further includes: the terminal device receives indication information that the network device is operating in sleep mode; or, the terminal device is configured to have the first cell operating in sleep mode; or, the network device operates in sleep mode.

[0154] For example, during a first time period, the terminal device monitors PDCCH candidates corresponding to a PDCCH search space. When the terminal device detects a PDCCH in the PDCCH search space, the terminal device may communicate with the network device, such as receiving downlink data and / or transmitting uplink data; or the terminal device may assume that the network device has entered a downlink active state operating mode and / or an uplink active state operating mode.

[0155] Optionally, after the first time period ends, the terminal device does not monitor the terminal device wake-up signal, and / or the terminal device does not monitor the PDCCH candidates corresponding to the PDCCH search space.

[0156] In some embodiments, if the terminal device is configured with a terminal device wake-up signal resource, the terminal device monitors the terminal device wake-up signal within the first time period.

[0165] In some embodiments, if the terminal device is not configured with a terminal device wake-up signal resource, the terminal device monitors PDCCH candidates corresponding to the PDCCH search space during a first time period. For example, if the terminal device is not configured with a UE-WUS resource, the terminal device monitors PDCCH candidates corresponding to the PDCCH search space during the first time period.

[0166] Optionally, during the first time period, the terminal device monitors PDCCH candidates corresponding to the PDCCH search space, including: when the terminal device detects the PDCCH in the PDCCH search space, the terminal device may communicate with the network device, for example, receive downlink data and / or transmit uplink data; or the terminal device may assume that the network device enters a downlink active state working mode and / or enters an uplink active state working mode. Optionally, after the first time period ends, the terminal device no longer monitors the PDCCH candidates in the PDCCH search space.

[0167] Optionally, after the first time period ends, the terminal device does not monitor the PDCCH candidates corresponding to the PDCCH search space.

For example, during the first time period, when the first UE-WUS resource is located before the first PDCCH search space in the time domain, the terminal device monitors the UE-WUS resource.

[0172] In some embodiments, the terminal device monitors the terminal device wake-up signal, including:

[0178] In some embodiments, during a first time period, if a time domain position of a resource corresponding to a first PDCCH search space is before a time domain position of a first terminal device wake-up signal resource, the terminal device monitors the PDCCH candidate corresponding to the PDCCH search space. For example, during the first time period, when the first PDCCH search space is before a first UE-WUS resource in the time domain, the terminal device monitors the PDCCH search space before the first UE-WUS resource.

[0179] Optionally, within the first time period, before the time domain position of the first terminal device wake-up signal resource, the terminal device monitors the PDCCH candidates corresponding to the PDCCH search space.

[0185] Optionally, after the first time period ends, the terminal device does not monitor the terminal device wake-up signal, and / or the terminal device does not monitor the PDCCH candidates corresponding to the PDCCH search space.

[0186] In this embodiment, when the terminal device is configured with UE-WUS resources and PDCCH search space, the terminal device monitors the terminal device wake-up signal and the resources that appear earlier in the time domain position in the PDCCH candidates corresponding to the PDCCH search space, so that the downlink transmission requirements of the network device can be known as early as possible, reducing transmission delay.

[0239] For details not described in detail in the network device side embodiment, please refer to the above method embodiment on the terminal device side.

[0240] The technical solution of this application is introduced and explained below through several exemplary embodiments.

[0241] In an exemplary embodiment, a terminal device is configured with gNB-WUS resources for sending gNB-WUS messages to a network device. For ease of description, this embodiment uses an FDD (Frequency Division Duplexing) system as an example (i.e., the terminal device is configured with an uplink carrier and a downlink carrier). However, it should be understood that this embodiment is also applicable to a TDD (Time Division Duplexing) system, and this application is not limited thereto.

[0242] As shown in Figure 4, a terminal device is configured with a gNB-WUS resource on an uplink carrier and a PDCCH search space on a downlink carrier. When a terminal device sends a gNB-WUS on a gNB-WUS resource (for example, when the terminal device requires downlink synchronization or uplink service transmission, the terminal device may send a gNB-WUS on the gNB-WUS to wake up the network), the terminal device may start a first timer starting from the start of the first PDCCH search space after sending the gNB-WUS. During the first timer, the terminal device monitors the PDCCH search space.

[0243] Optionally, the gNB-WUS resource from which the terminal device sends the gNB-WUS is a valid gNB-WUS resource. For example, the gNB-WUS resource is a gNB-WUS resource when the network device is in sleep mode.

[0244] Optionally, the PDCCH search space includes a terminal device-specific PDCCH search space and / or a public PDCCH search space.

[0245] Optionally, the PDCCH search space includes a search space associated with a specific RNTI (Radio Network Temporary Identifier). For example, the PDCCH search space includes a search space associated with a C-RNTI (Cell-Radio Network Temporary Identifier) ​​or a CS-RNTI (Configured Scheduling Radio Network Temporary Identifier) ​​or an MCSC-RNTI (Modulation and Coding Scheme Cell-Radio Network Temporary Identifier).

[0246] In some cases, if the terminal device receives a PDCCH sent by a network device within the PDCCH search space within the running time of the first timer, then the terminal device can communicate with the network device, such as receiving downlink data and / or sending uplink data; or, the terminal device can assume that the network device enters a downlink activated state working mode and / or enters an uplink activated state working mode.

[0247] Optionally, if the terminal device receives a PDCCH sent by the network device in the PDCCH search space within the running time of the first timer, the first timer may be restarted or the running time of the first timer may be extended.

[0248] In some cases, if the terminal device does not receive the PDCCH sent by the network device in the PDCCH search space within the running time of the first timer, the terminal device may send the gNB-WUS again using the gNB-WUS resources after the running time of the first timer expires.

[0249] Optionally, after the running time of the first timer ends, the terminal device no longer monitors the PDCCH search space.

[0250] Optionally, the gNB-WUS resources within the first timer running time are invalid gNB-WUS resources; or, the terminal device cannot send gNB-WUS through the gNB-WUS resources within the first timer running time.

[0251] In this embodiment, when the network device is in sleep mode, the terminal device can send a wake-up signal to the network device through the gNB-WUS resource, so that the network device can be informed of the transmission requirements of the terminal device, thereby avoiding the disadvantage that the network device cannot serve the terminal device for a long time in sleep mode, resulting in a large communication transmission delay of the terminal device.

[0252] In another exemplary embodiment, the terminal device is configured with UE-WUS resources, which are used by the network device to send the UE-WUS to the terminal device. For ease of description, this embodiment takes an FDD system as an example (i.e., the terminal device is configured with an uplink carrier and a downlink carrier). It should be understood that this embodiment can also be applied to a TDD system, and this application is not limited to this.

[0253] As shown in Figure 5, the terminal device is configured with UE-WUS resources and PDCCH search space on the downlink carrier. The terminal device obtains first time period information (in this example, the first time period information can be first window information, for example, the first window can be a time window for the network device to decide to enter the sleep mode state, and the terminal device can obtain the first window information based on the configuration information of the network device). During the first time period, the terminal device listens to the UE-WUS on the UE-WUS resource (in this example, if the network device wakes up from the sleep mode state, the terminal device can be awakened by sending the UE-WUS on the UE-WUS resource).

[0254] Optionally, the UE-WUS resource is a public UE-WUS resource. For example, the network device may wake up a group of terminal devices or wake up all terminal devices in the cell by sending a UE-WUS on the UE-WUS resource.

[0255] Optionally, the UE-WUS resource is a UE-WUS resource dedicated to the terminal device. For example, the network device can wake up the terminal device by sending a UE-WUS on the UE-WUS resource.

[0256] In some cases, if the terminal device monitors the UE-WUS on the UE-WUS resources within the first window, then the terminal device monitors the PDCCH search space associated with the UE-WUS resources; and / or, if the terminal device does not monitor the UE-WUS on the UE-WUS resources within the first window, then the terminal device does not monitor the PDCCH search space associated with the UE-WUS resources.

[0257] Further optionally, if the terminal device receives a PDCCH sent by a network device within the PDCCH search space, the terminal device can communicate with the network device, such as receiving downlink data and / or sending uplink data; or, the terminal device can assume that the network device enters a downlink activated state working mode and / or enters an uplink activated state working mode.

[0258] Optionally, the PDCCH search space includes a terminal device-specific PDCCH search space and / or a public PDCCH search space.

[0259] Optionally, the PDCCH search space includes a search space associated with a specific RNTI, for example, the PDCCH search space includes a search space associated with a C-RNTI, a CS-RNTI, or a MCSC-RNTI.

[0260] Optionally, if the terminal device receives a PDCCH sent by the network device within the PDCCH search space within the first window, the length of the first window may be extended.

[0261] Optionally, after the first window ends, the terminal device no longer monitors the UE-WUS resource.

[0262] Optionally, the UE-WUS resources used by the network device to send the UE-WUS are valid UE-WUS resources; or, the UE-WUS resources within the first window are valid UE-WUS resources.

[0263] Optionally, the UE-WUS resources outside the first window are invalid UE-WUS resources; or, the terminal device does not monitor the UE-WUS resources after the end of the first window.

[0264] In this embodiment, when the network device wakes up from the sleep mode, the network device can wake up the terminal device by sending UE-WUS on the UE-WUS resource, so that the terminal device can perform downlink and / or uplink transmission with the network device, thereby avoiding the disadvantage that the network device cannot serve the terminal device for a long time in the sleep mode, resulting in too large a communication transmission delay of the terminal device.

[0265] In another exemplary embodiment, a terminal device is configured with gNB-WUS resources and UE-WUS resources. The gNB-WUS resources are used by the terminal device to send gNB-WUS messages to the network device, and the UE-WUS resources are used by the network device to send UE-WUS messages to the terminal device. For ease of description, this embodiment uses an FDD system as an example (i.e., the terminal device is configured with an uplink carrier and a downlink carrier). It should be understood that this embodiment can also be applied to a TDD system, and this application is not limited to this.

[0266] As shown in Figure 6, a terminal device is configured with gNB-WUS resources on an uplink carrier and UE-WUS resources and a PDCCH search space on a downlink carrier. When a terminal device sends a gNB-WUS on a gNB-WUS resource (for example, when the terminal device requires downlink synchronization or uplink service transmission, the terminal device may send a gNB-WUS on the gNB-WUS to wake up the network), the terminal device may start a first timer. During the first timer's duration, the terminal device monitors the downlink channel or signal.

[0267] In some cases, the terminal device may start a first timer from the starting position of the first UE-WUS resource after sending the gNB-WUS. During the running time of the first timer, the terminal device monitors the UE-WUS resource, as shown in Figure 6.

[0268] Optionally, if the terminal device detects UE-WUS on the UE-WUS resources within the running time of the first timer, then the terminal device detects the PDCCH search space associated with the UE-WUS resources; and / or, if the terminal device does not detect UE-WUS on the UE-WUS resources within the running time of the first timer, then the terminal device does not detect the PDCCH search space associated with the UE-WUS resources.

[0269] In some cases, the terminal device may start a first timer from the starting position of the UE-WUS resource or PDCCH search space that appears first after sending the gNB-WUS. During the running time of the first timer, the terminal device listens to the UE-WUS resource or PDCCH candidate, for example, the terminal device listens to the UE-WUS resource and the resource that appears first in the PDCCH search space.

[0270] As an example but not a limitation, as shown in Figure 7, if the first UE-WUS resource is located before the first PDCCH search space, the start time of the first timer is the starting time of the first UE-WUS resource, and the terminal device preferentially monitors the UE-WUS resource during the running time of the first timer.

[0271] Optionally, if the terminal device detects UE-WUS on the UE-WUS resources within the running time of the first timer, then the terminal device detects the PDCCH search space associated with the UE-WUS resources; and / or, if the terminal device does not detect UE-WUS on the UE-WUS resources within the running time of the first timer, then the terminal device does not detect the PDCCH search space associated with the UE-WUS resources.

[0272] As an example and not a limitation, as shown in FIG8 , if the first PDCCH search space is located before the first UE-WUS resource, the start time of the first timer is the start time of the first PDCCH search space, and the terminal device first monitors the PDCCH candidate within the running time of the first timer. Optionally, the terminal device monitors the PDCCH search space within a time period from the running time of the first timer to the starting position of the first UE-WUS resource.

[0273] Optionally, the terminal device starts from the first UE-WUS resource and preferentially monitors the UE-WUS resource during the running time of the first timer.

[0274] Optionally, if the terminal device detects UE-WUS on the UE-WUS resources within the running time of the first timer, then the terminal device detects the PDCCH search space associated with the UE-WUS resources; and / or, if the terminal device does not detect UE-WUS on the UE-WUS resources within the running time of the first timer, then the terminal device does not detect the PDCCH search space associated with the UE-WUS resources.

[0275] Optionally, the gNB-WUS resource from which the terminal device sends the gNB-WUS is a valid gNB-WUS resource. For example, the gNB-WUS resource is a gNB-WUS resource when the network device is in sleep mode.

[0276] Optionally, the PDCCH search space includes a terminal device-specific PDCCH search space and / or a public PDCCH search space.

[0277] Optionally, the PDCCH search space includes a search space associated with a specific RNTI, for example, the PDCCH search space includes a search space associated with a C-RNTI, a CS-RNTI, or a MCSC-RNTI.

[0278] In some cases, if the terminal device receives a PDCCH sent by a network device within the PDCCH search space within the running time of the first timer, then the terminal device can communicate with the network device, such as receiving downlink data and / or sending uplink data; or, the terminal device can assume that the network device enters a downlink activated state working mode and / or enters an uplink activated state working mode.

[0279] Optionally, if the terminal device receives a PDCCH sent by the network device in the PDCCH search space within the running time of the first timer, the first timer may be restarted or the running time of the first timer may be extended.

[0280] In some cases, if the terminal device does not receive the PDCCH sent by the network device in the PDCCH search space within the running time of the first timer, or the terminal device does not receive the UE-WUS sent by the network device on the UE-WUS resources within the running time of the first timer, then the terminal device may send the gNB-WUS again through the gNB-WUS resources after the running time of the first timer ends.

[0281] Optionally, after the running time of the first timer ends, the terminal device no longer monitors the UE-WUS resource, and / or the terminal device no longer monitors the PDCCH search space.

[0282] Optionally, the gNB-WUS resources within the first timer running time are invalid gNB-WUS resources; or, the terminal device cannot send gNB-WUS through the gNB-WUS resources within the first timer running time.

[0283] Optionally, the UE-WUS resources used by the network device to send the UE-WUS are valid UE-WUS resources; or, the UE-WUS resources within the running time of the first timer are valid UE-WUS resources.

[0284] Optionally, the UE-WUS resources after the first timer running time ends are invalid UE-WUS resources; or, the terminal device does not monitor the UE-WUS resources after the first timer running time ends.

[0285] In this embodiment, when the terminal device is configured with gNB-WUS resources and UE-WUS resources, the network device can enter an activated state based on the gNB-WUS of at least one terminal device, and can then provide services for terminal devices with business needs in the system, including the at least one terminal device, thereby avoiding the disadvantage that the network device cannot serve the terminal device for a long time in the sleep mode, resulting in too large a communication transmission delay for the terminal device.
