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

The access network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with access network device functions may be different, for example, in the 5G NR system, they are called gNodeB or gNB.

[0046] Before introducing the technical solution of this application, some background technical knowledge involved in this application is first introduced and explained. The following related technologies can be combined arbitrarily with the technical solution of the embodiment of this application as optional solutions, and they all belong to the protection scope of the embodiment of this application. The embodiment of this application includes at least part of the following contents.

[0047] 1. Network energy saving background

[0048] Network energy saving is of great significance to environmental sustainability, reducing environmental impact (reducing greenhouse gas emissions), and saving operating costs. As 5G becomes more popular in various industries and geographical areas, it is necessary to support very high data transmission rates to handle more advanced services and applications (such as XR (Extended Reality)), and network deployment becomes denser, using more antennas, larger bandwidth and more frequency bands. Considering the impact of 5G on the environment, controlled and new solutions need to be developed to enhance network energy saving.

[0049] Energy consumption has become a key part of the operator's operational expenditure (OPEX). According to a report by the GSMA (Global System for Mobile communications Association), the energy cost of mobile networks accounts for about 23% of the total operating cost. Most of the energy consumption comes from the radio access network, more specifically, from the active antenna unit (AAU), among which data centers and fiber transmission account for a smaller share. The power consumption of a radio access can be divided into two parts: the dynamic part only includes the power consumption when data is being sent or received; the static part includes the power consumption for the necessary operation of the radio access equipment at all times, including the power consumption when no data is being sent or received.

[0050] Therefore, based on the above purposes, it is necessary to study and develop network energy consumption models, KPIs (Key Performance Indicators), evaluation methods, etc. on the network equipment side to determine and study network energy-saving technologies in target deployment scenarios. Among them, the power consumption model on the terminal device side that has been defined can be used as a reference. The 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 in 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.

[0051] It is worth noting that the study not only evaluates the potential network energy-saving gains, but also needs to evaluate and balance the impact on network and user performance by observing KPIs such as spectrum efficiency, capacity, user perceived throughput (UPT), latency, UE power consumption, complexity, handover performance, call drop rate, initial access performance, SLA security-related KPIs, etc. The study should avoid having a significant impact on the above KPIs.

[0052] 2. Network energy-saving technology

[0053] In a network energy-saving system, in order to save energy, the network device can enter a sleep mode state (or the network device enters an energy-saving mode) when the service load is relatively light or there is no service load. Table 1 shows a schematic diagram of a network device energy consumption model.

[0054] Table 1 Network equipment energy consumption model reference

[0055]

[0056]

[0057] However, when the network device enters the sleep mode state, if the terminal device has business arriving, it cannot communicate with the network device in time, so the terminal device's business may not be transmitted for a long time. To solve this problem, one possible implementation method is that the network device configures a base station wake-up signal (gNBwakeupsignal, gNB-WUS) resource for the terminal device. Even if the network device is in sleep mode, it may detect whether the terminal device has sent a wake-up request on this resource. When the terminal device has business arriving, a wake-up request can be sent 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.

[0058] 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.

[0059] Please refer to Figure 2, which shows a flow chart of a wireless communication method provided by an embodiment of the present application. The method can be applied to the network architecture shown in Figure 1 above. The method may include at least one of the following steps:

[0060] Step 210: The network device sends first configuration information to the terminal device, where the first configuration information is used to determine a wake-up signal resource, where the wake-up signal resource includes a resource used to send a wake-up signal to the network device.

[0061] Correspondingly, the terminal device receives the first configuration information.

[0062] In some embodiments, the wake-up signal is a signal for waking up a network device. For a network device that supports configuring a sleep mode, it can configure a wake-up signal resource for a terminal device. The terminal device can send a wake-up signal to the network device through the wake-up signal resource. If the network device receives the wake-up signal, the transmission requirement of the terminal device can be known. The wake-up signal can be called a network device wake-up signal, or a base station wake-up signal, or a gNB-WUS. The wake-up signal resource can be called a network device wake-up signal resource, or a base station wake-up signal resource, or a gNB-WUS resource.

[0063] Step 220: The terminal device determines a first wake-up signal resource according to the first configuration information. The first wake-up signal resource includes a wake-up signal resource that can be used by the terminal device.

[0064] The terminal device determines the wake-up signal resource available to it according to the first configuration information. In the embodiment of the present application, the wake-up signal resource available to it determined by the terminal device according to the first configuration information is referred to as the first wake-up signal resource.

[0065] In some embodiments, the terminal device uses the first wake-up signal resource to send a wake-up signal to the network device. For example, when the terminal device needs to wake up the network device, such as for uplink transmission or synchronization, the terminal device can use the first wake-up signal resource to send a wake-up signal to the network device.

[0066] In some embodiments, the first configuration information is used to determine the wake-up signal resource, including: the first configuration information is used to determine at least one group of wake-up signal resources, wherein the at least one group of wake-up signal resources includes the first wake-up signal resource. Optionally, the first wake-up signal resource includes some or all of the resources in the at least one group of wake-up signal resources.

[0067] In some embodiments, the terminal device determines the first wake-up signal resource based on the first configuration information, including: the terminal device determines at least one group of wake-up signal resources based on the first configuration information; the terminal device determines the first wake-up signal resource based on the at least one group of wake-up signal resources, and the first wake-up signal resource includes part or all of the wake-up signal resources in the above-mentioned at least one group of wake-up signal resources.

[0068] Optionally, a group of wake-up signal resources corresponds to one or more wake-up signal resource configurations.

[0069] It should be understood that in the embodiment of the present application, different wake-up signal resources include at least one of the following situations:

[0070] The time domain location of the wake-up signal resources is different;

[0071] The frequency domain location of the wake-up signal resource is different;

[0072] The sequence associated with the wake-up signal resources is different.

[0073] In an embodiment of the present application, the terminal device can obtain the wake-up signal resource configured for it by the network device, and then determine the first wake-up signal resource that can be used according to its own needs. When the network device is in sleep mode, the terminal device can use the above-mentioned first wake-up signal resource to send a wake-up signal to the network device. After the network device is awakened, it provides services for the terminal device, thereby avoiding the network device being unable to serve the terminal device for a long time in sleep mode, resulting in the disadvantage that the communication transmission delay of the terminal device is too large, thereby improving the transmission performance between the terminal device and the network device.

[0074] In some embodiments, the first configuration information is carried by at least one of the following information: system message, RRC (Radio Resource Control) signaling, MAC CE (MAC Control Element), and DCI (Downlink Control Information).

[0075] Exemplarily, when the terminal device is an idle or inactive terminal device, the first configuration information is carried via a system message.

[0076] Exemplarily, when the terminal device is a terminal device in a connected state, the first configuration information is carried by at least one of RRC signaling, MAC CE, and DCI. For example, the first configuration information is carried by RRC signaling; or, the first configuration information is carried by RRC signaling and DCI; or, the first configuration information is carried by MACCE; or, the first configuration information is carried by RRC signaling and MACCE.

[0077] In some embodiments, the first configuration information is carried by RRC signaling, and the RRC signaling is used to indicate at least one group of wake-up signal resources. The first configuration information is used to determine the wake-up signal resources, wherein the wake-up signal resources include at least one group of wake-up signal resources. When the terminal device receives the RRC signaling carrying the first configuration information, the terminal device can determine at least one group of wake-up signal resources based on the first configuration information carried in the RRC signaling. Subsequently, the terminal device can determine the first wake-up signal resource based on the at least one group of wake-up signal resources. Among them, the first wake-up signal resource includes some or all of the resources in the at least one group of wake-up signal resources.

[0078] In some embodiments, the first configuration information is carried by RRC signaling and DCI, and the RRC signaling is used to indicate at least one group of wake-up signal resources, and the DCI is used to indicate activation or deactivation of one or more groups of wake-up signal resources in at least one group of wake-up signal resources. The first configuration information is used to determine the wake-up signal resources, wherein the wake-up signal resources include one or more groups of wake-up signal resources activated in at least one group of wake-up signal resources. When the terminal device receives the RRC signaling carrying the first configuration information, the terminal device can determine at least one group of wake-up signal resources based on the first configuration information carried in the RRC signaling; further, when the terminal device receives the DCI carrying the first configuration information, the terminal device can determine one or more groups of wake-up signal resources activated in the at least one group of wake-up signal resources based on the first configuration information carried in the DCI. Subsequently, the terminal device can determine the first wake-up signal resource based on the activated one or more groups of wake-up signal resources. Among them, the first wake-up signal resource includes some or all of the resources in the activated one or more groups of wake-up signal resources.

[0079] In some embodiments, the first configuration information is carried by a MAC CE, and the MAC CE is used to indicate at least one group of wake-up signal resources. The first configuration information is used to determine the wake-up signal resources, wherein the wake-up signal resources include at least one group of wake-up signal resources. When the terminal device receives the MAC CE carrying the first configuration information, the terminal device can determine at least one group of wake-up signal resources based on the first configuration information carried in the MAC CE. Subsequently, the terminal device can determine the first wake-up signal resource based on the at least one group of wake-up signal resources. The first wake-up signal resource includes some or all of the resources in the at least one group of wake-up signal resources. Optionally, the first wake-up signal resource includes the wake-up signal resource after the MAC CE takes effect.

[0080] In some embodiments, the first configuration information is carried by RRC signaling and MAC CE, and the RRC signaling is used to indicate at least one group of wake-up signal resources, and the MAC CE is used to indicate activation or deactivation of one or more groups of wake-up signal resources in the at least one group of wake-up signal resources. The first configuration information is used to determine the wake-up signal resources, wherein the wake-up signal resources include one or more groups of wake-up signal resources activated in the at least one group of wake-up signal resources. When the terminal device receives the RRC signaling carrying the first configuration information, the terminal device can determine at least one group of wake-up signal resources based on the first configuration information carried in the RRC signaling; further, when the terminal device receives the MAC CE carrying the first configuration information, the terminal device can determine one or more groups of wake-up signal resources activated in the at least one group of wake-up signal resources based on the first configuration information carried in the MAC CE. Subsequently, the terminal device can determine the first wake-up signal resource based on the activated one or more groups of wake-up signal resources. Among them, the first wake-up signal resource includes some or all of the resources in the activated one or more groups of wake-up signal resources. Optionally, the first wake-up signal resource includes the wake-up signal resource after the MAC CE takes effect.

[0081] In some embodiments, the at least one group of wake-up signal resources includes multiple groups of wake-up signal resources, and different groups of wake-up signal resources have at least one of the following characteristics:

[0082] (1) At least one wake-up signal resource included in different groups of wake-up signal resources is different;

[0083] Exemplarily, the wake-up signal resources included in different groups of wake-up signal resources are different.

[0084] (2) Different groups of wake-up signal resources have different priorities;

[0085] Exemplarily, the multiple groups of wake-up signal resources include a first group of wake-up signal resources and a second group of wake-up signal resources, wherein the first group of wake-up signal resources corresponds to a first priority, the second group of wake-up signal resources corresponds to a second priority, and the first priority is higher than the second priority. The terminal device can select the wake-up signal resources of the corresponding group based on different priorities to send a wake-up signal to the network device.

[0086] Optionally, the priority is associated with at least one of the request channel, purpose and service type. The terminal device can determine the associated priority according to at least one of the request channel, purpose and service type, and then select the wake-up signal resource of the group corresponding to the priority to send the wake-up signal to the network device.

[0087] (3) Different groups of wake-up signal resources correspond to different request channels;

[0088] (4) Different groups of wake-up signal resources correspond to different purposes;

[0089] (5) Different groups of wake-up signal resources correspond to different service types;

[0090] Exemplarily, the multiple groups of wake-up signal resources include a first group of wake-up signal resources and a second group of wake-up signal resources, wherein the first group of wake-up signal resources corresponds to requesting an uplink channel or signal transmission, and the second group of wake-up signal resources corresponds to requesting a downlink channel or signal transmission. The terminal device can select the corresponding group of wake-up signal resources to send a wake-up signal to the network device based on different request channels or purposes or service types.

[0091] For example, when a terminal device has uplink services to be transmitted, the terminal device selects resources from the first group of wake-up signal resources corresponding to the requested uplink channel or signal transmission to send a wake-up signal to the network device; correspondingly, the network device receives the wake-up signal based on the first group of wake-up signal resources, and then learns that the terminal device has an uplink transmission requirement, thereby allocating uplink resources for the uplink channel or signal transmission to the terminal device.

[0092] For another example, when a terminal device has a synchronization requirement, the terminal device selects resources in the second group of wake-up signal resources corresponding to the requested downlink channel or signal transmission to send a wake-up signal to the network device; correspondingly, the network device receives the wake-up signal based on the second group of wake-up signal resources, and then it can be known that the terminal device has a synchronization requirement, thereby sending a downlink channel or signal for synchronization to the terminal device, such as sending SSB (Synchronization Signal and PBCH block) or CSI-RS (Channel State Information Reference Signal) to the terminal device.

[0093] Optionally, different priorities are associated with different request channels; or, different priorities are associated with different purposes; or, different priorities are associated with different service types.

[0094] Exemplarily, the multiple groups of wake-up signal resources include a first group of wake-up signal resources and a second group of wake-up signal resources, wherein the first group of wake-up signal resources corresponds to requesting uplink channel or signal transmission, and the first group of wake-up signal resources are associated with a first priority, and the second group of wake-up signal resources corresponds to requesting downlink channel or signal transmission, and the second group of wake-up signal resources are associated with a second priority. Optionally, the first priority is higher than the second priority; or, the first priority is lower than the second priority.

[0095] For example, when the terminal device has a synchronization requirement, the terminal device selects resources in the second group of wake-up signal resources corresponding to the requested downlink channel or signal transmission to send a wake-up signal to the network device; when the terminal device has uplink services to be transmitted, the terminal device selects resources in the first group of wake-up signal resources corresponding to the requested uplink channel or signal transmission to send a wake-up signal to the network device; since if the terminal device is not synchronized, it is impossible to transmit uplink services to the network device, it can be assumed that the priority of synchronization is higher than the priority of uplink service transmission, or, in other words, the second priority associated with the second group of wake-up signal resources is higher than the first priority associated with the first group of wake-up signal resources.

[0096] (6) Different groups of wake-up signal resources are associated with different terminal devices.

[0097] Exemplarily, the multiple groups of wake-up signal resources include wake-up signal resources of multiple terminal devices, and different terminal devices determine the wake-up signal resources that they can use from the multiple groups of wake-up signal resources according to the configuration information of the network device.
