Communication method, terminal device and network device
[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on February 8, 2024, with application number 202410177949.2 and invention name “A communication method, terminal equipment and network equipment”, the entire contents of which are incorporated by reference into this application. Technical Field
[0002] The present application relates to the field of communications, and in particular to a communication method, terminal equipment, and network equipment. Background Art
[0003] When a terminal device (such as a UE) is in an inactive state or an idle state, the network can establish a connection with the UE and communicate with it through paging.
[0004] Currently, the UE can monitor the paging message through a main receiving module (MR) configured therein, and then establish an RRC connection with the access network device after monitoring the paging message, and switch to a connected state.
[0005] When the UE uses the MR to monitor the paging message, a large power consumption overhead will occur due to the long time the MR is awakened. Summary of the Invention
[0006] The present application provides a communication method, terminal equipment, and network equipment, which enable both the UE and the network to accurately and reasonably determine whether to use the LR to monitor paging messages.
[0007] To achieve the above technical objectives, this application adopts the following technical solutions:
[0008] In a first aspect, a communication method is provided, which is applied to a terminal device. The method includes: receiving first configuration information, the first configuration information including first indication information or first time information. The first indication information is used to enable the terminal device to determine whether to monitor a wake-up message WUS. The first time information is used by the terminal device to determine whether to monitor the wake-up message. The wake-up message is used to wake up a main receiving module MR of the terminal device. Based on the first configuration information, the LR is started to monitor the wake-up message. Alternatively, based on the first configuration information, the MR is started to monitor a paging message.
[0009] In this way, the terminal can determine whether to start the LP-WUS solution based on the received information (such as the first indication information or the first time information), and monitor the MR through the LR, thereby saving the power consumption of the MR always being awake, or not start the LP-WUS and directly perform paging monitoring through the MR.
[0010] Optionally, the first configuration information includes the first indication information, and starting the LR to monitor the wake-up information according to the first configuration information includes: starting the LR to monitor the wake-up information when the MR startup time is less than the paging cycle. The paging cycle is determined based on at least one monitoring cycle configured for the terminal device.
[0011] Optionally, starting the MR to monitor the paging message according to the first configuration information includes: starting the MR to monitor the paging message when the startup time of the MR is greater than the paging cycle.
[0012] This example solution provides an implementation of the solution when the UE receives the first indication information. In this example, the UE can trigger the determination of whether to monitor WUS, that is, whether to activate the LP-WUS solution, based on the network's enable indication. In this implementation, the UE can specifically determine whether to monitor WUS based on the startup time of its own MR and the selected monitoring period (such as the paging period).
[0013] Optionally, the method further includes: determining the paging cycle from at least one listening cycle configured for the terminal device. The at least one listening cycle configured for the terminal device includes at least one of the following: a cell default DRX cycle, a UE-specific DRX cycle, an eDRX cycle in an idle state, an inactive DRX or eDRX cycle.

In this example, the UE can trigger a decision based on the network's enable indication and the received first time information (e.g., Tmax) to determine whether to monitor for WUS, i.e., whether to initiate the LP-WUS solution. In this implementation, the UE can specifically determine whether to monitor for WUS based on its own MR startup time and Tmax.
[0018] Optionally, before receiving the first configuration information, the method further includes: sending first capability information, where the first capability information includes MR startup time.

[0020] Optionally, after sending the first capability information, the method further includes: receiving first RRC connection release information.
[0021] Optionally, the first RRC connection release information includes the first configuration information.

[0143] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.
[0144] First, some of the nouns involved in the embodiments of this application are explained.
[0145] (1) Terminal: This term may also be referred to as user equipment (UE), user terminal, mobile station (MS), or mobile terminal (MT). A terminal may be a mobile phone or a wearable device (such as a smartwatch). It may also be referred to as simply a terminal.
[0146] In some embodiments of the present application, the terminal device may be configured with an application processor (AP) and a modem (also called a baseband processor, abbreviated as MD).
[0147] The AP can support the terminal device's interface display capabilities. The AP can also execute corresponding responses based on user operations received on the terminal device's interface. In addition, the MD can support the terminal device's digital processing capabilities.
[0148] In some embodiments, a main receiver (MR) may be configured in the terminal. The MR's operating states include awake and asleep. When the MR is awake, it supports the terminal's reception of wireless signals (e.g., paging messages). Correspondingly, if the terminal needs to receive wireless signals while the MR is asleep, it must first change the MR's state from asleep to awake.
[0149] In some other embodiments, the terminal may also be configured with a low-power receiver (LR). The LR is used to detect a wake-up signal for the MR using low power consumption. After the LR receives the wake-up signal, the terminal may begin changing the MR's state from sleep to awake. The wake-up signal may also be referred to as a WUS.
[0150] (2) LTE: This can be understood as the wireless access network of the 4G network. In the LTE network (commonly known as the 4G network), due to the evolutionary relationship, the access network part is called the Evolved UMTS Terrestrial Radio Access Network (E-UTRAN). In this application, the meaning of LTE is the same as that of E-UTRAN, both referring to the access network part of the 4G network. Terminal devices can access LTE through 4G base stations (such as eNBs).
[0151] (3) NR: It can be understood as the radio access network of the 5G network. In the 5G network, the access network part is called the Next Generation Radio Access Network (NG-RAN or NG RAN). In this application, the meaning of NR is the same as that of NG-RAN (or NG RAN), both referring to the access network part of the 5G network. Terminal devices can access LTE through 5G base stations (such as gNB). In this application, the 5G network can also be referred to as the NR network.
[0152] It's understandable that both LTE and NR are access networks. The access network uses wired or wireless connections and communication technologies to connect end users to the core network (also known as the backbone) in a step-by-step manner, establishing connectivity. The access network is the edge of the network, the part closest to users and often referred to as the "last mile."
[0153] In the embodiments of the present application, an access network device (such as an eNB in a 5G network, a gNB in a 4G network, etc.) of an access network may correspond to one or more cells. Each cell corresponds to a portion of the coverage area of the access network device. The collection of coverage areas of one or more cells of an access network device may constitute the complete coverage area of the access network device.
[0154] (4) Core Network: Its main functions are to provide user connections, user management, and service delivery. It serves as a bearer network and provides an interface to external networks. Establishing user connections includes functions such as mobility management (MM), call management (CM), switching / routing, and recording notifications (combined with intelligent network services to complete connections to intelligent network peripheral devices).
[0155] It's understandable that the core network of a 4G network is the Evolved Packet Core (EPC). The EPC network is the core network of a 4G mobile communications network. It falls within the core network category and provides traditional mobile network capabilities, such as user subscription data storage, mobility management, and data exchange, while also providing users with an ultra-high-speed Internet experience. The core network of a 5G network is the 5G Core (abbreviated as 5GC). 5GC uses general-purpose network function virtualization equipment to replace the dedicated communication equipment of 4G networks.
[0156] It should be noted that, in some embodiments, the core network can be obtained by integrating EPC and 5GC. That is to say, the core network can include both network elements in EPC and network elements in 5GC. For example, the core network may include access and mobility management function (AMF) network element, mobility management entity (MME) network element, serving gateway (SGW) network element, packet data network gateway (PGW) network element, session management function (SMF) network element, user plane function (UPF) network element, unified data management function (UDM) network element and home subscriber server (HSS) network element, etc.
[0157] In some embodiments of the present application, the core network may include converged network elements obtained from network elements in the EPC and network elements in the 5GC. For example, SMF+PGW-C, UPF+PGW-U, UDM+HSS, etc. Among them, PGW-C is the control plane node of the PGW network element, and PGW-U is the user plane node of the PGW network element.
[0158] (5) Terminal status. Take the case of a terminal communicating in a 5G network as an example. The terminal may also be referred to as an NR UE. The Radio Resource Control (RRC) status of an NR UE may include: IDLE mode, Connected mode, and Inactive mode.
[0159] When the RRC state of the terminal is in the idle state mode, the terminal can be said to be in the idle state. When the RRC state of the terminal is in the connected state mode, the terminal can be said to be in the connected state. When the RRC state of the terminal is in the inactive state mode, the terminal can be said to be in the inactive state.
[0160] When the terminal is in the idle state, the RRC connection with all access network devices is disconnected. When the terminal is in the connected state, an RRC connection is established with at least one access network device, and the terminal can communicate with the core network through this access network device. When the terminal is in the inactive state, the RRC connection between the terminal and the access network device is suspended. If the terminal needs to communicate with the access network device, it needs to restore the RRC connection to the connected state.
[0161] When the terminal is idle or inactive, the MR in the terminal can be in a dormant state. If a LR is configured in the terminal, the LR can be awake when the terminal is idle or inactive to monitor wake-up information for the MR. Alternatively, when the terminal is idle or inactive, the LR can enter an awake state at a corresponding time based on the terminal configuration or network configuration to monitor wake-up information for the MR.
[0162] (6) Paging. When in idle or inactive state, the terminal can monitor paging messages at paging occasions (PO) according to the configured monitoring period to receive downlink triggered services. The network can configure the monitoring period for the terminal through DRX configuration or eDRX configuration.
[0163] Take the case where the terminal is in an idle or inactive state as an example.
[0164] In some embodiments, before a PO arrives, the terminal may start a MR so that when a PO arrives, the terminal may monitor a paging message through the MR.
[0165] When LR is configured in the terminal, before the PO arrives, the terminal can start MR according to the WUS received from the LR.
[0166] In other embodiments, when the PO arrives, the MR may not be started yet or is completely started. In this way, after the MR is completely started (the working state is switched to the awake state), the terminal can monitor the paging message through the MR.
[0167] As an example, refer to FIG1 , which is a schematic diagram of a communication architecture provided in an embodiment of the present application.
[0168] In the example shown in Figure 1, during communication, a terminal can establish an RRC connection with an access network device. The access network device can also establish a communication connection with a core network device. Thus, when performing uplink services, the terminal can transmit information to the access network device via the RRC connection, which in turn allows the access network to transmit the information to the corresponding core network device. Correspondingly, when performing downlink services, the core network device can send downlink service data to the access network device. Based on the downlink service data, the access network device can transmit relevant data and information to the terminal via the RRC connection.
[0169] For example, if the terminal currently accesses a 5G network, the corresponding access network equipment may include a 5G base station (eNB). The core network equipment may include various core network devices corresponding to the 5G network, such as the AMF and MME in the 5G network.
[0170] For example, the terminal currently accesses a 4G network. The corresponding access network equipment may include a 4G base station (gNB). The core network equipment may include various core network devices corresponding to the 4G network, such as the AMF and MME in the 4G network.
[0171] Each network element in the core network can also be called a functional entity, which can be a network element implemented on dedicated hardware, a software instance running on dedicated hardware, or an instance of a virtualized function on an appropriate platform.
[0172] It should be understood that the names of all network elements in this application are only examples. In future communications, such as 6G, they may also be called other names, or, in future communications, such as 6G, the network elements involved in this application may also be replaced by other entities or devices with the same functions, etc., and this application does not limit this. A unified explanation is given here and will not be repeated later. Optionally, the various network elements in the embodiments of the present application may be communication devices, or chips or chip systems that can be operated in the communication devices, etc., and this embodiment of the present application does not limit this.
[0173] It is understandable that the core network in the network architecture shown in Figure 1 may also include other devices, network elements, network entities, or network subsystems, such as a Policy Control Function (PCF) network element, and this application does not limit this. It should be noted that this application does not limit the distribution method of each network element in the core network. The specific distribution method can be referred to relevant technical documents, and this application does not elaborate on this.
[0174] 2 , which illustrates the logical interaction of the network configuring a listening period for the UE after a communication connection is established between the UE and the network.
[0175] As shown in Figure 2, in this example, the UE can establish an RRC connection with an access network device (such as an eNB). The access network device can also establish a communication connection with a core network device (such as a 5GC).
[0176] In this way, the UE can communicate and interact with the core network device through the RRC connection with the access network device.
[0177] In some embodiments, as shown in S201 of Figure 2 , the access network device may send a cell default DRX configuration message to the UE. The cell default DRX configuration message may carry information about a cell default DRX cycle corresponding to the cell accessed by the UE.
[0178] Thus, the UE can obtain the default DRX cycle of the cell. In some implementations, the default DRX cycle of the cell can be configured in the range of 320ms to 2.56s.
[0179] In other embodiments, as shown in S202 of FIG. 2 , the core network device may perform UE-specific DRX negotiation with the UE through the access network device. Thus, the core network device may send a UE-specific DRX configuration message to the UE through the access network device. The UE-specific DRX configuration message may include information about a UE-specific DRX cycle.
[0180] Thus, the UE can obtain the UE-specific DRX cycle. In some implementations, the UE-specific DRX cycle can be configured in the range of 2.56s to 2.91h.
[0181] In other embodiments, as shown in S203 of FIG2 , the core network device may perform idle eDRX negotiation with the UE through the access network device. Thus, the core network device may send an idle eDRX configuration message to the UE through the access network device. The idle eDRX configuration message may carry information about an idle eDRX cycle (IDEL eDRX cycle).
[0182] Thus, the UE can obtain the eDRX cycle in the idle state. In some implementations, the eDRX cycle in the idle state can be configured in the range of 320ms to 2.56s.
[0183] In other embodiments, as shown in S204 of Figure 2, the access network device may send an inactive listening cycle configuration message to the UE. The inactive listening cycle configuration message may carry information about the inactive DRX or eDRX cycle (Cell default (e) DRX cycle) configured by the access network device for the UE.
[0184] Thus, the UE can obtain the inactive DRX or eDRX cycle. In some implementations, the inactive DRX or eDRX cycle can be configured in the range of 320ms to 10.24s.
[0185] In some implementations, S204 may be performed before the UE disconnects the RRC connection with the access network device of the current access cell. Thus, the network can configure a reasonable monitoring period for the UE that is about to enter the inactive state through S204.
[0186] Therefore, as shown in FIG. 2 , after completing S204 , the UE may release the RRC connection with the access network device, and then enter an inactive state or an idle state.
[0187] It should be noted that at least four ways of configuring a listening period for a UE are provided in FIG2 . In a specific implementation, the network may configure one or more listening periods for a UE by one or more of steps S201 to S204 in FIG2 .
[0188] For example, the network may configure the above four listening periods to the UE through S201 to S204 respectively, and thus the UE may store the configured four listening periods respectively.
[0189] Under existing protocol regulations, when a UE monitors paging messages, it can select one of the four stored monitoring periods based on actual circumstances and perform MR wakeup and paging message monitoring based on the selected monitoring period. In the following examples, the selected monitoring period may also be referred to as the paging period for monitoring paging, or simply the paging period.
[0190] For example, according to the protocol content of 38.204, the UE may select the shortest listening cycle among all configured listening cycles as the paging cycle.
[0191] For another example, the UE may determine the paging cycle according to a configured policy.
[0192] Based on this, the UE can use the activated MR to monitor paging messages when a PO arrives according to the monitoring period. Alternatively, after a PO arrives, the UE can wait for the MR to be activated and use the activated MR to monitor paging messages.
[0193] For example, refer to FIG3 , which is a schematic diagram of a logical interaction of inter-device communication provided in an embodiment of the present application.
[0194] As shown in Figure 3, the process may include:
[0195] S301. The core network device sends a paging message to the access network device.
[0196] Exemplarily, the paging message may include a paging message. The paging message may be used to instruct the access network device to perform paging on the UE.
[0197] In some embodiments, the paging message may include the listening period that the core network device has configured for the UE.
[0198] 2 , taking the case where the core network device has configured a UE-specific DRX cycle for the UE as an example, the paging message may include information about the UE-specific DRX configuration cycle.
[0199] For example, if the core network device has configured an eDRX cycle in the idle state for the UE, the paging message may include information about the eDRX cycle in the idle state.
[0200] The paging message may also carry the device identifier of the UE that needs to be paged.
[0201] S302: The access network device synchronizes monitoring period configuration.
[0202] Exemplarily, the access network device may initiate paging to the UE according to the paging message.
[0203] Since the paging monitoring of the UE is actually performed within the monitoring period, the access network device can synchronize the monitoring period configuration with the UE before initiating paging.
[0204] It can be understood that, taking the case where the UE is configured with four monitoring periods as shown in FIG. 2 as an example.
[0205] In this way, the access network device can know the default DRX cycle of the cell configured by the access network device for the UE, and the inactive DRX or eDRX cycle.
[0206] The access network device may also determine the UE-specific DRX cycle configured by the core network device for the UE and the eDRX cycle in the idle state according to the paging message from the core network.
[0207] Therefore, the access network device can achieve synchronization with the listening period configuration of the UE according to the various listening periods that have been configured for the UE and the same listening period selection policy as the UE.
[0208] Exemplarily, the access network device may select the listening cycle with the shortest duration among all listening cycles configured for the UE as the paging cycle.
[0209] In this way, the access network device can perform paging to the UE according to the paging cycle.
[0210] S303: The access network device sends paging scheduling PDCCH information to the UE.
[0211] Exemplarily, the access network device may send paging scheduling PDCCH information to the UE when the PO corresponding to the paging cycle arrives.
[0212] In some embodiments, the paging scheduling PDCCH information may include downlink control information (DCI).
[0213] The DCI may include PDSCH scheduling information. The PDSCH scheduling information may include the time-frequency position of the PDSCH in the paging message sent by the access network device.
[0214] S304: The UE monitors the paging scheduling PDCCH information and determines the PDSCH scheduling information indicated by the DCI.
[0215] Illustratively, the UE may start the MR to monitor the paging message according to a monitoring period determined by itself.
[0216] After the MR is started, the UE can monitor the paging scheduling PDCCH information through the MR.
[0217] In this way, the UE can determine the PDSCH scheduling information indicated therein according to the paging scheduling PDCCH information.
[0218] S305: The UE determines that the paging message includes its own device identifier.
[0219] Exemplarily, the UE may determine the time-frequency position of the device identifier of the device to be paged by the network according to the PDSCH scheduling information.
[0220] Correspondingly, the UE can obtain the device identifier of the device that the network wants to page from the time-frequency position.
[0221] The UE can determine that the network needs to communicate with the UE based on the monitored device identifiers, including its own device identifier, and then complete the paging process and perform subsequent network access to communicate with the network according to the accessed network.
[0222] S306: The UE sends an RRC establishment request to the access network device. Exemplarily, the RRC establishment request may include an RRC Connection Request.
[0223] S307: The access network device sends an RRC connection setup complete message to the UE. Exemplarily, the RRC connection setup complete message may include RRC Connection Setup Complete.
[0224] In this way, through S306 to S307, the UE can re-establish a connection with the access network device. Based on this, the core network device can transmit downlink service data and information to the UE through the access network device, thereby realizing downlink service functions.
[0225] In other embodiments of the present application, in order to distinguish between a paging message sent by a core network device to an access network device and a paging message sent by the access network device during paging of a UE, in the description of this application, a paging message sent by a core network device to an access network device may also be referred to as a paging indication, such as a first paging indication. The paging message sent by the access network device during paging of a UE may include a first paging message, etc.
[0226] It should be noted that, in the implementation of the solution shown in FIG3 , the network side carries the device identifier of the UE to be paged in the paging message so that the UE can determine whether it has accessed the network.
[0227] In other implementations, the network and the UE may also perform paging of the UE in combination with the device group identifier indicated by the PEI.
[0228] It is understandable that, in the implementation of the solution shown in FIG3 , if the UE needs to monitor the paging scheduling PDCCH information in a timely manner, the MR of the UE needs to be able to complete startup earlier.
[0229] For example, the UE may start the MR before the PO arrives.
[0230] However, although this can ensure that the UE can monitor the paging scheduling PDCCH information in time, the MR is in an awake state for a long time to monitor the paging information, which will bring about a large power consumption overhead.
[0231] To this end, a LR can be further configured in the UE. The LR can have lower operating power consumption. The MR is activated only when the UE can receive a WUS through the LR.
[0232] For example, the access network device may send a WUS to the UE in advance before initiating paging. Correspondingly, the UE may wake up the MR when receiving the WUS via the LR.
[0233] In this way, the UE can wake up the MR earlier and monitor the paging scheduling PDCCH information.
[0234] As an example, refer to FIG4 , which is a schematic diagram of a timing comparison of a UE performing various operations.
[0235] In the example of FIG. 4 , the PO may arrive at a time 42 , and later at a time 44 , depending on the selected listening period.
[0236] The UE may activate the LR and start monitoring the WUS before time 41. The UE may monitor the WUS at time 41 before time 42. Therefore, the UE may start MR from this time 41.
[0237] It is understandable that it takes a certain amount of time for an MR to switch from a sleep state to a wake-up state. In the following examples, the time it takes for an MR to switch from a sleep state to a wake-up state is referred to as the MR startup time.
[0238] Thus, after time 41, the MR startup time has elapsed, and at time 43, after time 42, the MR completes startup and enters the awake state. Then, after time 43, the UE can monitor the paging scheduling PDCCH information through the MR. For example, at time 43, the UE monitors the paging scheduling PDCCH information through the MR.
[0239] 3 , after monitoring the paging scheduling PDCCH information, the UE can complete network access according to S304 to S307 . Thus, after completing network access, the UE can receive downlink service data and information from the core network from the access network device.
[0240] 4 , in this example, after receiving the WUS at time 41 and after the MR activation time has elapsed, at time 43, the UE can complete the MR activation and subsequent reception of the paging scheduling PDCCH information within the listening period corresponding to the PO at time 42.
[0241] In this way, the UE can start receiving downlink service data and information from the network during the monitoring period from time 42 to time 44. At the same time, due to the existence of the LR monitoring mechanism, the MR is in a sleep state before time 41, which can save corresponding power consumption.
[0242] It should be noted that, in the configuration of the LR monitoring mechanism, the MR startup time is taken as 400ms or 800ms as an example.
[0243] Corresponding to the configuration mechanism of the listening period provided in Figure 2, if the UE / base station paging cycle is short (e.g., less than the MR startup time), the UE will only start the MR when it detects a WUS, which may result in the MR not being able to complete startup within a listening period. Corresponding to the example in Figure 4, in this scenario, the moment 43 when the MR completes startup may be postponed until after the next PO arrives 44.
[0244] 2 , taking the MR startup time of 800 ms as an example, when the selected monitoring period is 320 ms, 640 ms, etc., the MR startup time may be longer than the monitoring period.
[0245] Then, the UE cannot monitor the paging scheduling PDCCH information through the activated MR during the monitoring period between time 42 and time 44. This will obviously delay the subsequent establishment of the RRC connection between the UE and the access network device, and further lead to delayed reception of downlink service data and information.
[0246] In this case, if the MR is always awake, the UE can monitor the paging scheduling PDCCH information earlier. Therefore, during the monitoring period between time 42 and time 44, the UE can access the access network device, thus ensuring timely reception of downlink service data and information.
[0247] Based on this, the technical solution provided in the embodiments of the present application enables the UE and network equipment (such as access network equipment) to flexibly select whether to use the LR monitoring mechanism. This allows the UE to reasonably achieve power savings based on the LR mechanism, while also avoiding delayed downlink data and information reception due to a long MR startup time or a short selected monitoring period.
[0248] The following describes the solution provided by the embodiment of the present application in detail with reference to the accompanying drawings. The solution shown in FIG4 , in which the LR receives a WUS and wakes up the MR to monitor the paging signal, is referred to as the LP-WUS solution.
[0249] Referring to Figure 5, there is shown a schematic diagram of a process interaction of a communication method provided in an embodiment of the present application. In this example, base station 51 may be a 4G base station, a 5G base station, or a base station of another network standard. The core network device may be a core network device corresponding to base station 51. As shown in Figure 5, the solution may include:
[0250] S501: A UE sends capability information 52 to a base station 51. The capability information 52 may include information about the time it takes to start a MR for the UE. In this embodiment of the present application, the capability information 52 may be included in the first capability information.
[0251] Exemplarily, the capability information 52 may include UECapabilityInformation information.
[0252] Optionally, the capability information 52 may also carry a capability identifier indicating whether the UE supports the LP-WUS solution. For example, the capability identifier may be configured to indicate that the UE supports the LP-WUS solution, or the capability identifier may be configured to indicate that the UE does not support the LP-WUS solution.
[0253] In the following implementation, the UE supporting the LP-WUS solution is taken as an example.
[0254] Optionally, before executing S501, the UE may also establish an RRC connection with the base station 51, and the base station 51 may also establish a communication connection with the core network device. In this way, the UE can register with the core network device through the RRC connection with the base station 51, thereby enabling communication interaction between the UE and the core network device through the base station 51. During this process, the UE may be in a connected state.
[0255] Optionally, before the UE executes S501, the base station 51 may also send a
[0256] The UECapabilityEnquiry instruction is used to instruct the UE to report capability information. Correspondingly, the UE can send the capability information 52 to the base station 51.
[0257] S502: The base station 51 sends RRC connection release information to the UE.
[0258] Exemplarily, the RRC connection release information may include RRC Connection Release information. The base station 51 may instruct the UE to disconnect the current RRC connection through the RRC connection release information.
[0259] Correspondingly, after receiving the RRC connection release information, the UE may disconnect the RRC connection with the base station 51. In this example, after disconnecting the RRC connection with the base station 51, the UE may switch from the connected state to the idle state.
[0260] S503: The base station 51 sends capability information 53 to the core network device. In the embodiment of the present application, the capability information 53 may be included in the second capability information.
[0261] Exemplarily, the base station 51 may forward the capability information 52 from the UE to the core network device.
[0262] For example, the base station 51 may generate capability information 53 according to the received capability information 52. The capability information 53 may carry the information of the UE's MR startup time acquired in S501.
[0263] In some embodiments, the base station 51 may carry the UE's MR startup time information and the UE's representation (such as a device ID) in the capability information 53 and send it to the core network device. This allows the core network or device to store the corresponding relationship between the device ID and the MR startup time, thereby correctly maintaining the UE and the corresponding capability information.
[0264] Optionally, after the base station 51 disconnects the RRC connection with the UE, the base station 51 deletes the acquired capability information 52 .
[0265] In this way, through the solution shown in Figure 5, the UE can report the MR startup time information to the base station when reporting capabilities, and the base station then reports it to the core network device. The core network device (such as the AMF in the core network device) can store the corresponding relationship between the obtained device ID and the MR startup time.
[0266] Based on this, when the core network equipment needs to page the UE and provide downlink services, the MR startup time can be sent to the base station, so that the base station can flexibly choose whether to use the LP-WUS solution in conjunction with the UE based on the MR startup time.
[0267] For example, referring to FIG6 , which is a schematic diagram of an interaction flow of another communication method provided in an embodiment of the present application, the solution may include:
[0268] S601: A base station 61 sends low power consumption configuration information 62 to a UE. In the embodiment of the present application, the low power consumption configuration information 62 may be included in first configuration information.
[0269] Exemplarily, the base station 61 may send the low power configuration information 62 to all UEs within the coverage of the cell of the base station 61 in a broadcasting manner. In this example, it is assumed that the UE is currently located within the coverage of the cell of the base station 61.
[0270] It is understandable that the base station 61 and the base station 51 shown in FIG. 5 may be the same base station or different base stations.
[0271] In some embodiments, the low power configuration information 62 may include indication information A. The indication information A may enable the UE to perform a preset determination of the LP-WUS solution. The preset determination mechanism will be described in detail later.
[0272] It will be understood that in the embodiments of the present application, "enable" may correspond to "enable." Enabling a function of the UE may also correspond to turning on a switch corresponding to the function in the UE, so that the UE provides the function. In some embodiments, indication information A enables the UE to perform a preset determination of the LP-WUS scheme, which may correspond to the UE performing a preset determination of the LP-WUS scheme upon receiving indication information A.
[0273] In some embodiments, the indication information A may also be referred to as first indication information. The first indication information may be used to enable the UE to determine whether to monitor the WUS.
[0274] In some other embodiments, the low power configuration information 62 may further include LP-WUS configuration information. The LP-WUS configuration information may include at least one of the following: a time-frequency position corresponding to the WUS, coding information corresponding to the WUS, and a signal strength condition.
[0275] The time-frequency position corresponding to the WUS is used to indicate the time-frequency position of the WUS in the data packet when the base station 61 sends the WUS. The coding information corresponding to the WUS is used to indicate the coding method and decoding method of the WUS when the base station 61 sends the WUS.
[0276] The signal strength condition corresponds to a signal condition indicating that the LP-WUS scheme can be executed.
[0277] Exemplarily, the signal strength condition may include a signal strength threshold. Upon receiving the signal strength condition, the UE may measure the current downlink communication channel. The UE may determine that the signal conditions for executing the LP-WUS solution are met when the measured signal strength of the current downlink communication channel is greater than the strength threshold indicated by the signal strength condition.
[0278] S602 : The UE receives low power consumption configuration information 62 .
[0279] In some embodiments, taking the low power consumption configuration information 62 including indication information A as an example, the UE may trigger the execution of the following S603 according to the received indication information A.
[0280] In some embodiments, for example, the low power configuration information 62 includes a signal strength condition. The UE may perform measurements of the corresponding downlink communication channel based on the received signal strength condition. Optionally, the UE may trigger execution of S603 below when the signal strength of the current downlink communication channel exceeds a strength threshold indicated by the signal strength condition.
[0281] S603: The UE determines whether the MR startup time is less than the paging cycle. In this example, S603 corresponds to the preset determination of whether the indication information A involved in S601 corresponds to the enabled LP-WUS solution.
[0282] Exemplarily, before executing S603 , the UE may determine a paging cycle according to one or more configured DRX cycles and / or eDRX cycles.
[0283] For example, taking the case where the UE is configured with a cell default DRX cycle, a UE-specific DRX cycle, an eDRX cycle in an idle state, an inactive DRX, or an eDRX cycle, the configured one or more DRX cycles and / or eDRX cycles may include at least one of the following: a cell default DRX cycle, a UE-specific DRX cycle, an eDRX cycle in an idle state, an inactive DRX, or an eDRX cycle.
[0284] The UE may use the shortest cycle among the configured DRX cycles or eDRX cycles as the paging cycle.
[0285] For another example, the UE may determine the paging cycle according to a configured policy.
[0286] In this example, the UE may also perform subsequent processing according to whether the MR startup time is less than the paging cycle.
[0287] For example, the UE may jump to execute S604a when the MR startup time is less than the paging cycle; the UE may jump to execute S604b when the MR startup time is not less than (eg, greater than) the paging cycle.
[0288] S604a: The UE starts LR and monitors WUS.
[0289] For example, when the MR startup time is less than the paging cycle, the UE may determine to use the LP-WUS solution to monitor the paging message, thereby saving the power consumption of the MR when it is in the awake state for a long time.
[0290] In some embodiments, the UE may activate the LR and begin to monitor the WUS via the low power receiver.
[0291] Optionally, the UE may monitor the WUS according to information such as the time-frequency position corresponding to the WUS and the coding information corresponding to the WUS in the low power configuration information 62 .
[0292] S604b: The UE starts the MR and monitors the paging message.
[0293] Exemplarily, when the time taken to start the MR is not less than (eg, greater than) the paging cycle, the UE may not use the LP-WUS solution and may directly use the MR to monitor the paging message.
[0294] It is understandable that if the MR startup time is not less than the paging cycle, it indicates that the MR startup time is relatively short, and the UE is more time-sensitive when monitoring paging messages. In this way, the UE can directly start the MR to complete the MR startup as soon as possible and receive the paging message sent by the base station in a timely manner.
[0295] S605: The core network device sends a paging message 63 to the base station 61. The paging message 63 may be included in a first paging indication.
[0296] In some embodiments, the paging message 63 may carry the UE's MR startup time.
[0297] In other embodiments, the paging message 63 may also carry the DRX cycle or eDRX cycle that the core network device has configured for the UE. For example, the paging message 63 may include the UE-specific DRX cycle and / or the eDRX cycle in the idle state that the core network device has configured for the UE.
[0298] S606. The base station 61 synchronizes the paging cycle configuration.
[0299] Exemplarily, the base station 61 may adopt the same strategy as the UE to determine the paging cycle from one or more DRX cycles and / or eDRX cycles configured for the UE. The one or more configured DRX cycles and / or eDRX cycles may include at least one of the following: a cell default DRX cycle, a UE-specific DRX cycle, an eDRX cycle in an idle state, an inactive DRX cycle, or an eDRX cycle.
[0300] For example, the base station 61 may determine the DRX cycle or eDRX cycle with the shortest duration configured for the UE as the paging cycle. In another example, the UE may determine the paging cycle according to a configured policy.
[0301] S607: The base station 61 determines whether the MR startup time is less than the paging cycle.
[0302] For example, the base station 61 may use a processing mechanism similar to S603 in the UE to determine whether the MR startup time is less than the paging cycle. Based on this, the base station 61 may trigger subsequent processing according to the determination result.
[0303] In some embodiments, the base station 61 may perform paging on the UE using the LP-WUS solution when the MR startup time is less than the paging cycle. For example, the base station 61 may perform S608a.
[0304] In some embodiments, the base station 61 may directly page the UE without using the LP-WUS solution if the MR startup time is not less than (eg, equal to or greater than) the paging cycle. For example, the base station 61 may execute S608b.
[0305] The following describes each of these steps. Taking the case where the MR startup time is less than the paging cycle as an example, the solution may further include S608a to S611a.
[0306] S608a: The base station 61 sends LP wake-up information 64 to the UE.
[0307] Exemplarily, the LP wake-up information 64 may include WUS information. The LP wake-up information 64 may be used to instruct the UE to start MR.
[0308] S609a: The UE starts the MR and monitors the paging message.
[0309] For example, the UE can determine that a paging message is coming via the LR based on the WUS included in the received LP wakeup information 64. Accordingly, the UE can start the MR so that the MR receives the paging message from the access network device after the MR is started.
[0310] S610a: The base station 61 sends paging scheduling PDCCH information 65 to the UE.
[0311] Exemplarily, the paging scheduling PDCCH information 65 may be sent to the UE by the base station 61 as part of a paging message sent by the access network device to the UE. In some embodiments, the paging scheduling PDCCH information 65 may be included in the first paging message.
[0312] In combination with the above description, the paging scheduling PDCCH information 65 may include DCI information, which is used to indicate the time-frequency position of the PDSCH in the data packet.
[0313] The corresponding UE can determine whether its own device ID is included according to the PDSCH indicated by the PDCCH information 65.
[0314] For example, if the PDSCH indicated by PDCCH information 65 carries the UE's own device ID, the UE can determine that the core network device needs to send downlink service data or information to the UE. In this way, the UE can execute the following S611a to access the network.
[0315] S611a: The UE establishes an RRC connection with the base station 61.
[0316] Thus, the UE can switch from the idle state to the connected state. In this way, the UE can obtain downlink service data or information sent by the core network device through the base station 61, thereby successfully completing the UE paging.
[0317] For example, the specific implementation of S611a can refer to S306-S307 in FIG3 , which will not be described in detail here.
[0318] In this way, when both the UE and the base station 61 determine that the LP-WUS solution can be used, the base station 61 and the UE can use the LP-WUS solution to successfully implement UE paging while saving power consumption caused by long-term MR wake-up.
[0319] In some other embodiments, taking the case where the time taken to start the MR is not less than the paging cycle as an example, the solution may further include S608b to S609b.
[0320] S608b: The base station 61 sends the UE paging scheduling PDCCH information 66. In combination with the above description of the access network device sending a paging message to the UE, in this example, the paging scheduling PDCCH message 66 may be included in the first paging message.
[0321] S609b: The UE establishes an RRC connection with the base station 61.
[0322] For example, the execution process of S608b to S609b may refer to the description of S303 to S307 in FIG. 3 , and their specific implementations may refer to each other.
[0323] It is understood that if the UE and base station 61 determine not to use the LP-WUS solution, base station 61 can directly initiate paging to the UE. Accordingly, since the UE's MR is awake, it can promptly receive the paging message sent by base station 61. This avoids downlink service delays caused by a short MR startup time and the use of the LP-WUS solution.
[0324] Figures 5 and 6 above provide an implementation of an embodiment of the present application. In Figure 6, the base station 61 carries indication information A in the low power configuration information 62, and the preset judgment includes judging whether the MR startup time is less than the paging cycle.
[0325] In other embodiments, the low power consumption configuration information configured by the access network device to the UE may also carry other information, and the corresponding preset judgment may also be implemented in other ways.
[0326] For example, refer to FIG7 , which is a schematic diagram of an interaction flow of another communication method provided in an embodiment of the present application. In the solution shown in FIG7 , the UE has reported the MR startup time to the network in the manner shown in FIG5 . The corresponding core network device also stores the UE's MR startup time.
[0327] As shown in Figure 7, the solution may include:
[0328] S701. A base station 71 sends low power consumption configuration information 72 to a UE. In some embodiments, the low power consumption configuration information 72 may be included in first configuration information.
[0329] Exemplarily, the base station 71 may send the low power configuration information 72 to all UEs within the cell coverage of the base station 71 in the form of broadcast. The base station 71 may be the same base station as the base station 51 shown in FIG5 or the base station 61 shown in FIG6, or may be a different base station.
[0330] In some embodiments, the low power configuration information 72 may include time information Tmax. The time information Tmax may indicate the maximum MR startup time supported by the network that can use LP-WUS. The time information Tmax may be pre-configured in the base station 71. The time information Tmax may correspond to the first time information.
[0331] In other embodiments, the low-power configuration information 72 may also include LP-WUS configuration information. The LP-WUS configuration information may include at least one of the following: the time-frequency position corresponding to the WUS, the encoding information corresponding to the WUS, and the signal strength condition. For details on this part, refer to the description of the low-power configuration information 62 in S601.
[0332] S702: The UE receives low power consumption configuration information 72. The execution of this process may refer to S602 in FIG6 .
[0333] In some embodiments, the UE may directly execute S703 after receiving the low power configuration information 72. In other embodiments, the UE may execute S703 after receiving the low power configuration information 72 and determining that the signal strength condition is satisfied (e.g., the signal strength of the downlink communication channel is greater than a strength threshold).
[0334] S703: The UE determines whether the MR startup time is less than Tmax. In this example, S703 corresponds to the preset judgment of the LP-WUS solution in this example.
[0335] Exemplarily, the UE may perform subsequent processing according to the relationship between the MR startup time and Tmax.
[0336] For example, the UE may jump to execute S704a when the MR startup time is less than Tmax; the UE may jump to execute S704b when the MR startup time is not less than (eg, greater than) the paging cycle.
[0337] S704a: The UE starts LR and monitors WUS.
[0338] For example, when the MR startup time is less than Tmax, the UE may determine to use the LP-WUS solution to monitor the paging message, thereby saving the power consumption of the MR when it is in the awake state for a long time.
[0339] S704b: The UE starts the MR and monitors the paging message.
[0340] Exemplarily, when the time consumed to start the MR is not less than (such as greater than) Tmax, the UE may not use the LP-WUS solution and may directly use the MR to monitor the paging message.
[0341] In this way, the UE can flexibly determine whether to use the LP-WUS solution for paging monitoring based on preset judgment, combined with its own MR startup time and the network's support capability for the LP-WUS solution.
[0342] Based on this, the network and UE can also implement subsequent solutions to implement UE paging under different mechanisms.
[0343] S705: The core network device sends a paging message 73 to the base station 71. The execution of this process may refer to S605 in Figure 6. The paging message 73 may correspond to the paging message 63 in S605.
[0344] S706: The base station 71 synchronizes the paging cycle configuration. The execution of this process may refer to S606 in FIG6 .
[0345] S707: The base station 71 determines whether the MR activation time is less than Tmax. It is understood that the base station 71 may receive a paging message 73 from the core network device in S705. The paging message 73 may include the UE's MR activation time.
[0346] In this way, similar to the preset judgment mechanism within the UE in S703, the base station 71 can also perform similar judgments to be consistent with the UE.
[0347] The base station 71 may perform paging on the UE through the LP-WUS solution when the MR startup time is less than Tmax. For example, the base station 71 may perform S708a.
[0348] In some embodiments, the base station 71 may directly page the UE without using the LP-WUS solution if the MR startup time is not less than (eg, equal to or greater than) Tmax. For example, the base station 71 may execute S708b.
[0349] Take the case where the MR startup time is less than Tmax as an example.
[0350] S708a: The base station 71 sends LP wake-up information 74 to the UE.
[0351] S709a: The UE starts the MR and monitors the paging message.
[0352] S710a: The base station 71 sends paging scheduling PDCCH information 75 to the UE.
[0353] S711a , the UE establishes an RRC connection with the base station 71 .
[0354] For example, the execution process of S708a-S711a may refer to the execution process of S608a-S611a in Figure 6. Based on this, the UE and the network can use the LP-WUS solution to smoothly implement UE paging while saving the power consumption overhead caused by long-term MR wake-up.
[0355] For example, the MR startup time is not less than Tmax. This solution may also include:
[0356] S708b: The base station 71 sends paging scheduling PDCCH information 76 to the UE.
[0357] S709b: The UE establishes an RRC connection with the base station 71.
[0358] For example, the execution process of S708b-S709b can refer to the execution process of S608b-S609b in Figure 6. Based on this, the UE and the network can directly monitor paging through the MR without using the LP-WUS solution. This avoids the delay of downlink services caused by the short MR startup time and the use of the LP-WUS solution.
[0359] It can be understood that in the above embodiments of the present application, based on the mechanism of the UE actively reporting the MR startup time as shown in FIG5 , the network can be aware of the UE's MR startup time.
[0360] Based on the solutions shown in FIG6 and FIG7 , two different preset judgment mechanisms are provided respectively, so that the UE and the network can reasonably and flexibly choose to use the LP-WUS solution or the MR direct monitoring to perform the UE paging process.
[0361] In addition, as shown in the descriptions of Figures 6 and 7, a possible implementation mechanism is provided: when the low-power configuration information includes a signal strength condition, the UE can trigger subsequent steps for using the LP-WUS scheme to monitor the paging signal when the signal strength of the current downlink communication channel is greater than the strength threshold indicated by the signal strength condition.
[0362] In the subsequent embodiments, the signal strength of the current downlink communication channel meeting the signal strength condition is taken as an example, and no further details are given.
[0363] In the implementation of the above solution, as shown in Figure 5, after the UE reports the MR startup time through capability information, it can disconnect the RRC connection with the access network device and then enter the idle state. When the UE enters the idle state, the access network device can release the relevant information (such as capability information) of the UE that has disconnected the RRC connection. In this way, in order to ensure that capability information such as MR startup time can be known by the network side (such as the core network), as shown in Figure 5, the access network device can transmit the capability information including the MR startup time to the core network device (such as AMF) for storage. Correspondingly, in the implementation of the solution as shown in Figure 6 or Figure 7, when the core network device sends a paging message, it can also send the MR startup time of the UE that needs to be paged to the access network device. In this way, the access network device can also know the MR startup time of the UE. This supports the preset judgment of the network side as shown in Figure 6 or Figure 7.
[0364] In other implementations, after reporting the MR initiation time and receiving the RRC connection release information from the base station, the UE may enter an inactive state. In this case, the access network equipment may continue to retain the information reported by the UE, such as the MR initiation time. For this scenario, embodiments of the present application also provide a communication method that enables the UE and the network to reasonably and flexibly choose whether to page the UE using the LP-WUS solution.
[0365] For example, referring to FIG8 , which is a schematic diagram of an interaction flow of another communication method provided in an embodiment of the present application, the solution may include:
[0366] S801. A UE sends information about a time consumption for MR startup to a base station 81. The information about a time consumption for MR startup may be included in first capability information.
[0367] Similar to the description in S501 in Figure 5, in this example, the UE may establish an RRC connection with the base station 81 before executing S801. In this way, the UE may execute S801 when it is in a connected state.
[0368] For example, in some embodiments, the UE may send the information about the MR startup time to the base station 81 in the form of capability information reporting. For example, the UE may carry the information about the MR startup time in the UECapabilityInformation information and send it to the base station 81.
[0369] Optionally, before sending UECapabilityInformation to the base station, the UE may receive a UECapabilityEnquiry instruction from the base station 81. In response to the UECapabilityEnquiry instruction, the UE may send UECapabilityInformation carrying the MR startup time to the base station 81.
[0370] In other embodiments, the UE may also send information about the MR startup time to the base station 81 by reporting auxiliary information. For example, after receiving the RRC Reconfiguration sent by the base station 81, the UE may send UE Assistance Information (UAI) carrying the MR startup time to the base station 81.
[0371] In this way, the access network device can know how long it takes to start the MR of the UE.
[0372] S802. The base station 81 sends RRC connection release information to the UE.
[0373] In some embodiments, the RRC connection release information may include LP-WUS configuration information. The LP-WUS configuration information may include at least one of the following: a time-frequency position of WUS transmission, coding information, and a signal strength condition.
[0374] For the description of the time-frequency position, coding information, and signal strength conditions sent by the WUS, reference may be made to the example in S601.
[0375] In some other embodiments, the RRC connection release information may further include a DRX or eDRX cycle when the UE is in an inactive state.
[0376] In this example, since the UE is about to switch from the connected state to the inactive state, the base station 81 may configure the DRX or eDRX cycle for the UE in the inactive state. This allows the UE to monitor paging messages based on the DRX or eDRX cycle in the inactive state and other configured DRX or eDRX cycles.
[0377] In conjunction with the example in FIG5 , in the example shown in FIG8 , the UE can switch to an inactive state after receiving the RRC connection release information. The corresponding access network device (e.g., base station 81) does not delete the relevant information of the UE (e.g., MR startup time). Therefore, base station 81 can store the MR startup time of the UE on its own, without having to report the UE capability information or auxiliary information, such as the MR startup time, to the core network for storage.
[0378] In conjunction with the examples in Figure 6 or Figure 7, in some embodiments of the present application, after the UE switches to the inactive state, the UE and the network can determine whether to page the UE according to the LP-WUS scheme in the manner as shown in Figure 6 or Figure 7.
[0379] For example, after the UE enters the inactive state, the UE and the network may determine whether to perform paging of the UE according to the LP-WUS solution in the manner shown in FIG6 .
[0380] The access network device (such as base station 81) can send low-power configuration information carrying indication information A to the UE in the form of broadcast. Correspondingly, the UE can judge whether the MR startup time is less than the paging cycle based on the indication information A. The UE can also start the MR as shown in S604a based on the judgment result, without using the LP-WUS scheme, and directly monitor the paging message; or, based on the judgment result, start the LR to monitor the WUS according to the LP-WUS scheme as shown in S604b. In addition, after receiving the paging message from the core network device, the base station 81 can also implement the scheme shown in S605-S611a or S605-S609b shown in Figure 6, and adopt a consistent scheme with the UE (such as using the LP-WUS scheme or not using the LP-WUS scheme) to achieve UE paging and network access.
[0381] In other embodiments, after the UE enters the inactive state, the UE and the network may also determine whether to perform paging of the UE according to the LP-WUS solution in the manner shown in FIG7 , thereby achieving reasonable access of the UE. Specific implementation is described in reference to FIG7 and will not be repeated here.
[0382] It can be understood that in the implementation of the solution provided in Figure 6 or Figure 7, the access network device can send low-power configuration information to the UE in the form of broadcasting, so as to instruct the UE to determine whether the LP-WUS solution needs to be used based on whether the MR startup time is less than the paging cycle, or based on whether the MR startup time is less than Tmax.
[0383] It should be noted that in other embodiments of the present application, based on the solution shown in Figure 8, when the base station 81 executes S802, that is, sends RRC connection release information to the UE, it can also send low power configuration information to the UE through the RRC connection release information.
[0384] Exemplarily, in this example, the RRC connection release information sent by the base station 81 to the UE may include at least one of the following: the time-frequency position, coding information, and signal strength conditions sent by the WUS; the DRX or eDRX cycle when the UE is in an inactive state; and low power configuration information 82.
[0385] The low power configuration information 82 may include any of the following:
[0386] Indication information A, time information Tmax.
[0387] For example, when the UE sends RRC connection release information, the low power configuration information 82 carried includes indication information A.
[0388] In this way, the UE can switch to the inactive state based on the received RRC connection release information. The UE can also execute S603-S604a or S603-S604b as shown in Figure 6 based on the indication information A. Correspondingly, after base station 81 receives the paging message from the core network device, base station 81 and the UE can also refer to S605-S611a or S605-S609b in Figure 6 respectively to execute paging for the UE and access the network.
[0389] For example, when the UE sends the RRC connection release information, the low power configuration information 82 carried includes the time information Tmax.
[0390] In this way, the UE can switch to the inactive state based on the received RRC connection release information. The UE can also execute S703-S704a or S703-S704b as shown in Figure 7 based on the time information Tmax. Correspondingly, after base station 81 receives the paging message from the core network device, base station 81 and the UE can also refer to S705-S711a or S705-S709b as shown in Figure 7 respectively to perform paging for the UE and access the network.
[0391] In this way, through the implementation and description of the solution shown in FIG8 , the UE and the network can reasonably and flexibly determine whether to use the LP-WUS solution for UE paging when the UE is in an inactive state.
[0392] In other embodiments of the present application, a communication method is provided that enables the UE and the network to reasonably and flexibly determine whether to use the LP-WUS scheme for UE paging. Based on this scheme, the UE does not need to report the MR initiation time to the network. The network and the UE can each determine whether to use the LP-WUS scheme for UE paging by configuring time information Tmin (or second time information).
[0393] For example, referring to FIG9 , which is a schematic diagram of an interaction flow of another communication method provided in an embodiment of the present application, the solution may include:
[0394] S901. A base station 91 sends low power consumption configuration information 92 to a UE. In some embodiments, the low power consumption configuration information 92 may be included in first configuration information.
[0395] Exemplarily, the base station 91 may send the low power configuration information 92 to all UEs within the coverage of the cell of the base station 91 in a broadcasting manner. In this example, it is assumed that the UE is currently located within the coverage of the cell of the base station 91.
[0396] In other embodiments, the low power configuration information 92 may also be transmitted to the UE via other means. For example, the base station 91 sends the low power configuration information 92 to the UE via an RRC connection release message.
[0397] In some embodiments, the low power configuration information 92 may include time information Tmin. This time information Tmin may be pre-configured in the base station 91, or may be configured by a core network device to the base station 91. This time information Tmin may be used to indicate the minimum paging cycle for the UE to monitor paging using the LP-WUS solution.
[0398] In other embodiments, the low power configuration information 92 may further include at least one of the following: a time-frequency position corresponding to the WUS, coding information corresponding to the WUS, and a signal strength condition.
[0399] The time-frequency position corresponding to the WUS is used to indicate the time-frequency position of the WUS in the data packet when the base station 91 sends the WUS. The coding information corresponding to the WUS is used to indicate the coding method and decoding method of the WUS when the base station 91 sends the WUS.
[0400] Similar to the description in FIG. 6 , the signal strength condition corresponds to a signal condition indicating that the LP-WUS scheme can be executed.
[0401] Exemplarily, the signal strength condition may include a signal strength threshold. Upon receiving the signal strength condition, the UE may measure the current downlink communication channel. The UE may determine that the signal conditions for executing the LP-WUS solution are met when the measured signal strength of the current downlink communication channel is greater than the strength threshold indicated by the signal strength condition.
[0402] S902 : The UE receives low power consumption configuration information 92 .
[0403] In some embodiments, taking the low power configuration information 92 including the time information Tmin as an example, the UE may trigger the execution of the following S903 according to the received time information Tmin.
[0404] In some embodiments, for example, the low power configuration information 92 includes a signal strength condition. The UE may perform measurements of the corresponding downlink communication channel based on the received signal strength condition. Optionally, the UE may trigger execution of S903 below when the signal strength of the current downlink communication channel exceeds a strength threshold indicated by the signal strength condition.
[0405] S903: The UE determines whether the paging cycle is greater than Tmin.
[0406] Exemplarily, before executing S903 , the UE may determine a paging cycle according to one or more configured DRX cycles and / or eDRX cycles.
[0407] In some embodiments, the UE may use the shortest duration of each configured DRX cycle or eDRX cycle as the paging cycle. The configured one or more DRX cycles and / or eDRX cycles may include at least one of the following: a cell default DRX cycle, a UE-specific DRX cycle, an idle state eDRX cycle, an inactive state DRX, or an eDRX cycle.
[0408] In other embodiments, the UE may determine the paging cycle according to a configured policy.
[0409] In this example, the UE may also perform subsequent processing according to whether the paging cycle is greater than Tmin.
[0410] For example, when the paging cycle is greater than Tmin, the UE may jump to execute S904a; when the paging cycle is not greater than (eg, less than or equal to) Tmin, the UE may jump to execute S904b.
[0411] S904a: The UE starts LR and monitors WUS.
[0412] For example, when the paging cycle is greater than Tmin, the UE may determine to use the LP-WUS solution to monitor paging messages, thereby saving the power consumption of the MR when it is in the awake state for a long time.
[0413] In some embodiments, the UE may activate the LR and begin to monitor the WUS via the low power receiver.
[0414] Optionally, the UE may monitor the WUS according to information such as the time-frequency position corresponding to the WUS and the coding information corresponding to the WUS in the low power configuration information 92 .
[0415] S904b: The UE starts the MR and monitors the paging message.
[0416] Exemplarily, when the paging cycle is not greater than (eg, less than or equal to) Tmin, the UE may not use the LP-WUS solution and may directly use the MR to monitor the paging message.
[0417] It is understandable that if the MR startup time is not less than the paging cycle, it indicates that the MR startup time is relatively short, and the UE is more time-sensitive when monitoring paging messages. In this way, the UE can directly start the MR to complete the MR startup as soon as possible and receive the paging message sent by the base station in a timely manner.
[0418] S905 . The core network device sends a paging message 93 to the base station 91 .
[0419] In some embodiments, the paging message 93 may also carry the DRX cycle or eDRX cycle that the core network device has configured for the UE. For example, the paging message 93 may include the UE-specific DRX cycle and / or the eDRX cycle in the idle state that the core network device has configured for the UE.
[0420] S906. The base station 91 synchronizes the paging cycle configuration.
[0421] Exemplarily, the base station 91 may adopt the same strategy as the UE to determine the paging cycle from one or more DRX cycles and / or eDRX cycles configured for the UE. The one or more configured DRX cycles and / or eDRX cycles may include at least one of the following: a cell default DRX cycle, a UE-specific DRX cycle, an eDRX cycle in an idle state, an inactive DRX cycle, or an eDRX cycle.
[0422] For example, the base station 91 may determine the DRX cycle or eDRX cycle with the shortest duration configured for the UE as the paging cycle. In another example, the UE may determine the paging cycle according to a configured policy.
[0423] S907: The base station 91 determines whether the paging cycle is greater than Tmin.
[0424] For example, the base station 91 may use a processing mechanism similar to that in S903 in the UE to determine whether the paging cycle is greater than Tmin. Based on this, the base station 91 may trigger subsequent processing according to the determination result.
[0425] In some embodiments, the base station 91 may perform paging on the UE using the LP-WUS scheme when the paging cycle is greater than Tmin. For example, the base station 91 may perform S908a.
[0426] In some embodiments, the base station 91 may directly page the UE without using the LP-WUS scheme when the paging cycle is not greater than (eg, less than or equal to) Tmin. For example, the base station 91 may execute S908b.
[0427] The following describes each of these steps. Taking the paging cycle as an example, the paging cycle is greater than Tmin. The solution may also include S908a to S911a.
[0428] S908a: The base station 91 sends LP wake-up information 94 to the UE.
[0429] Exemplarily, the LP wake-up information 94 may include WUS information. The LP wake-up information 94 may be used to instruct the UE to start MR.
[0430] S909a: The UE starts the MR and monitors the paging message.
[0431] For example, the UE can determine that a paging message is coming via the LR based on the WUS included in the received LP wake-up information 94. Accordingly, the UE can start the MR so that the MR receives a paging message (such as paging scheduling PDCCH information) from the access network device after completing the startup.
[0432] S910a: The base station 91 sends paging scheduling PDCCH information 95 to the UE.
[0433] Exemplarily, the paging scheduling PDCCH information 95 may be sent by the base station 91 to the UE as part of a paging message sent by the access network device to the UE.
[0434] In combination with the above description, the paging scheduling PDCCH information 95 may include DCI information, which is used to indicate the time-frequency position of the PDSCH in the data packet.
[0435] The corresponding UE can determine whether its own device ID is included according to the PDSCH indicated by the PDCCH information 95.
[0436] For example, if the PDSCH indicated by PDCCH information 95 carries the UE's own device ID, the UE can determine that the core network device needs to send downlink service data or information to the UE. In this way, the UE can execute the following S911a to access the network.
[0437] S911a : The UE establishes an RRC connection with the base station 91 .
[0438] Thus, the UE can switch to the connected state and continue to work. In this way, the UE can obtain the downlink service data or information sent by the core network device through the base station 91, thereby successfully completing the UE paging.
[0439] For example, the specific implementation of S911a can refer to S306-S307 in FIG3 , which will not be described in detail here.
[0440] In this way, when both the UE and the base station 91 determine that the LP-WUS solution can be used, the base station 91 and the UE can use the LP-WUS solution to successfully implement UE paging while saving power consumption caused by long-term MR wake-up.
[0441] In some other embodiments, taking the paging cycle as not greater than (such as less than or equal to) Tmin as an example, the solution may further include S908b to S909b.
[0442] S908b: The base station 91 sends paging scheduling PDCCH information 96 to the UE.
[0443] S909b: The UE establishes an RRC connection with the base station 91.
[0444] For example, the execution process of S908b to S909b may refer to the description of S303 to S307 in FIG. 3 , and their specific implementations may refer to each other.
[0445] It should be noted that, in the implementation of the solution shown in FIG9 , the base station 91 may be the same as any base station provided in the aforementioned embodiments, or may be different from any base station provided in any of the aforementioned embodiments.
[0446] Therefore, based on the implementation of the solution shown in Figure 9, compared with the solution descriptions related to Figures 6, 7, or 8, the UE does not need to disclose the MR startup time to the network. This solution implementation is not limited to the UE being in an idle state or inactive state.
[0447] In the implementation of the solution shown in FIG9 , the UE and the network side can respectively determine whether to use the LP-WUS solution for UE paging in a reasonable and flexible manner through the time information Tmin and the monitoring period (ie, paging period) actually selected by the UE.
[0448] In each of the above embodiments, the UE and the network may synchronously determine whether the LP-WUS solution needs to be used according to a preset judgment.
[0449] The preset judgment may include: judging whether the MR startup time is less than the paging cycle as shown in FIG6 , or judging whether the MR startup time is less than Tmax as shown in FIG7 , or judging whether the paging cycle is greater than Tmin as shown in FIG9 .
[0450] In other embodiments of the present application, after determining whether to use the LP-WUS solution, the network may notify the UE in the form of an indication message, so that the UE can perform paging monitoring according to the LP-WUS solution or directly initiate MR to perform paging monitoring based on the received indication message.
[0451] For example, referring to FIG10 , there is provided a schematic diagram of an interaction flow of a communication method according to an embodiment of the present application. As shown in FIG10 , the solution may include:
[0452] S1001. A core network device sends DRX assistance information 1002 to a base station 1001. In the embodiment of the present application, the DRX assistance information 1002 may be included in first DRX assistance information.
[0453] Exemplarily, the DRX assistance information 1002 may include information about the monitoring period that the core network device (such as AMF) has configured for the UE. The information about the monitoring period that has been configured for the UE may include: a UE-specific DRX period and / or an eDRX period in an idle state.
[0454] In some embodiments, the AMF may carry the DRX assistance information 1002 in the INITIAL CONTEXT SETUP REQUEST and send it to the base station 1001.
[0455] In some embodiments, before S1001, the UE has already accessed the network through base station 1001. For example, the UE has established an RRC connection with base station 1001. In another example, base station 1001 has established a communication connection with a core network device (such as AMF). In this way, the UE can register with the core network device through base station 1001 to achieve network access.
[0456] S1002. Base station 1001 synchronizes monitoring period configuration.
[0457] Exemplarily, the process of configuring the synchronous listening cycle may include: the base station 1001 may determine the paging cycle according to the listening cycle that has been configured for the UE.
[0458] It can be understood that the monitoring period that has been configured for the UE may include: the monitoring period configured for the UE by the core network device (such as the UE-specific DRX cycle and / or the eDRX cycle in the idle state), and / or the monitoring period configured for the UE by the access network device (such as the cell default DRX cycle and / or the inactive DRX or eDRX cycle).
[0459] In some embodiments, the base station 1001 may select the shortest duration from all configured listening cycles as the paging cycle. In other embodiments, the base station 1001 may determine the paging cycle according to a configured policy.
[0460] S1003. Base station 1001 sends RRC connection release information to the UE. The RRC connection release information may carry indication information B. In some embodiments, the indication information B may be included in the first configuration information.
[0461] Exemplarily, base station 1001 may determine whether to use the LP-WUS solution for UE paging based on the paging cycle. Base station 1001 may also send indication information B to the UE if it is determined to use the LP-WUS solution for UE paging. Indication information B instructs the UE to monitor paging messages using the LP-WUS solution.
[0462] In this example, the UE switches from the connected state to the inactive state according to the RRC connection release information sent by base station 1001. In this way, base station 1001 can include the indication information B in the RRC connection release information. This allows the UE to know that after entering the inactive state, it can use the LP-WUS solution to monitor paging messages.
[0463] It should be noted that, in different implementations, the specific implementation of the indication information B may be different.
[0464] In some implementations, the indication information B may correspond to a preset first field. For example, when the first field is configured to a first value (e.g., 1), it indicates that the LP-WUS solution is used. Thus, the base station 1001 may configure the first field to the first value in the RRC connection release information.
[0465] In some other implementations, indication information B may correspond to at least part of the LP-WUS configuration information. In conjunction with the foregoing description, the LP-WUS configuration information may include at least one of the following: the time-frequency position corresponding to the WUS, the coding information corresponding to the WUS, and the signal strength condition. Thus, when base station 1001 determines to use the LP-WUS solution for UE paging, it may include the LP-WUS configuration information in the RRC connection release message.
[0466] It is understandable that after receiving the RRC connection release information, the UE may switch the current connection state to an inactive state.
[0467] In addition, the UE may also determine to use the LP-WUS solution to perform paging monitoring after entering the inactive state according to the indication information B carried in the received RRC connection release information.
[0468] Exemplarily, the solution may include:
[0469] S1004: The UE starts the LR and monitors the WUS. In this way, the UE can start the MR when the LR receives the WUS later.
[0470] After that, when the base station 1001 receives a paging message from the core network device, it can page the UE through the LP-WUS solution. Exemplarily, the solution may include:
[0471] S1005. The core network device sends a paging message 1003 to the base station 1001.
[0472] S1006. The base station 1001 sends LP wake-up information 1004 to the UE.
[0473] S1007. The UE starts the MR and monitors the paging message.
[0474] S1008. The base station 1001 sends paging scheduling PDCCH information 1005 to the UE.
[0475] S1009. UE establishes an RRC connection with base station 1001.
[0476] It is understood that the execution process of S1005 to S1009 can refer to the implementation of the solution for using the LP-WUS solution for UE paging in the aforementioned embodiment. In the implementation of this solution shown in Figure 10, since base station 1001 has already determined that the LP-WUS solution needs to be used for paging, after receiving paging message 1003, base station 1001 does not need to perform steps such as determining the paging cycle and determining whether to use the LP-WUS solution. Accordingly, base station 1001 can directly perform paging for the UE using the LP-WUS solution.
[0477] In the solution provided in FIG10 above, the base station 1001 determines that the LP-WUS solution needs to be used to perform paging on the UE. In other embodiments, as shown in FIG11, a solution implementation is provided in which the access network device determines not to use the LP-WUS solution to perform paging on the UE.
[0478] Exemplarily, as shown in FIG11 , the solution may include:
[0479] S1101. A core network device sends DRX assistance information 1102 to a base station 1101. In the embodiment of the present application, the DRX assistance information 1102 may be included in first DRX assistance information.
[0480] S1102. The base station 1101 synchronizes the monitoring cycle configuration.
[0481] The execution of the above S1101 to S1102 may refer to S1001 and S1002 in FIG. 10 , respectively.
[0482] S1103. Base station 1101 sends an RRC connection release message to the UE. The RRC connection release message may carry indication information C. The indication information C indicates that the LP-WUS solution is not used. In some embodiments, the indication information C may be included in the first configuration information.
[0483] In this example, it is continued to be taken that the UE switches from the connected state to the inactive state according to the RRC connection release information sent by the base station 1101.
[0484] In this way, the base station 1101 may carry the indication information C in the RRC connection release information, so that the UE can know that after entering the inactive state, the LP-WUS solution is not used to monitor the paging message.
[0485] In conjunction with the description in S1003, in some implementations, the indication information C may correspond to a preset first field. For example, when the first field is configured to the second value (e.g., 0), it indicates that the LP-WUS solution is not used. Thus, the base station 1101 may configure the first field to the second value in the RRC connection release information.
[0486] In addition, in other embodiments of the present application, the function of carrying the indication information C in the RRC connection release information can also be implemented in other ways.
[0487] Exemplarily, the base station 1101 may instruct the UE not to use the LP-WUS solution for paging monitoring by not carrying the LP-WUS configuration information in the RRC connection release information.
[0488] In the example shown in FIG11 , after receiving the RRC connection release information, the UE may switch the current connection state to an inactive state.
[0489] In addition, the UE may also determine not to use the LP-WUS solution for paging monitoring after entering the inactive state according to the indication information C carried in the received RRC connection release information. For example, the UE may directly perform paging monitoring through the MR.
[0490] Exemplarily, the solution may include:
[0491] S1104. The UE starts the MR and monitors the paging message.
[0492] S1105 . The core network device sends a paging message 1103 to the base station 1101 .
[0493] S1106 . The base station 1101 sends paging scheduling PDCCH information 1104 to the UE.
[0494] S1107. The UE establishes an RRC connection with the base station 1101.
[0495] It is understood that the execution process of S1104 to S1107 can refer to the implementation of the solution for UE paging without using the LP-WUS solution in the aforementioned embodiment. In the implementation of the solution shown in Figure 11, since base station 1101 has already determined that it is not necessary to use the LP-WUS solution for paging, after receiving paging message 1103, base station 1101 does not need to perform steps such as determining the paging cycle and determining whether to use the LP-WUS solution. Accordingly, base station 1101 can directly send a paging message to the UE to facilitate the subsequent RRC connection with the UE.
[0496] In the examples of Figures 10 and 11 above, the UE switches from a connected state to an inactive state to perform paging monitoring. In this way, the access network device can carry corresponding indication information in the RRC connection release information to configure the UE to use the LP-WUS solution for paging monitoring, or to configure the UE not to use the LP-WUS solution for paging monitoring.
[0497] In other cases, the UE can enter the idle state from the connected state based on the received RRC connection release information. For this scenario, the embodiments of the present application also provide a corresponding solution implementation, so that the access network device can also indicate to the UE whether to use the LP-WUS solution or not. This allows both the access network device and the UE to perform subsequent paging based on the result determined by the access network device.
[0498] For example, referring to FIG12 , which is a schematic diagram of an interaction flow of another communication method provided in an embodiment of the present application, the solution may include:
[0499] S1201. A core network device sends DRX assistance information 1202 to a base station 1201. In the embodiment of the present application, the DRX assistance information 1202 may be included in second DRX assistance information.
[0500] Exemplarily, the DRX assistance information 1202 may include network DRX capability information. In this example, the network DRX capability information may correspond to the DRX capability information of the core network device, for example, the DRX capability information of the AMF.
[0501] In some embodiments, the DRX assistance information 1202 may include: a minimum value of the monitoring period supported by the AMF, and / or a maximum value of the monitoring period supported by the AMF. The monitoring period supported by the AMF may include a UE-specific DRX period configured by the AMF for the UE and / or an eDRX period in the idle state.
[0502] In other embodiments, the DRX auxiliary information 1202 may include: the minimum value of all listening periods that the core network device (such as AMF) has configured for the UE, and / or the maximum value of all listening periods that the core network device (such as AMF) has configured for the UE.
[0503] In other embodiments, the DRX auxiliary information 1202 may also include: the minimum value and / or maximum value of the listening period supported by the AMF, and the minimum value and / or maximum value of all listening periods that the core network device (such as AMF) has configured for the UE.
[0504] In the following example, the DRX auxiliary information 1202 includes the minimum value of the listening period supported by the AMF and / or the minimum value of all listening periods that the core network device (such as AMF) has configured for the UE.
[0505] It can be understood that in different implementations, when the core network device configures a monitoring period for the UE, the monitoring period configured by the core network device for the UE will not be less than the value of the monitoring period carried in the DRX auxiliary information 1202.
[0506] In some embodiments, the DRX assistance information 1202 may be carried in an AMF CONFIGURATION UPDATE. For example, the AMF may send the AMF CONFIGURATION UPDATE carrying the DRX assistance information 1202 to the base station 1201 during an NG interface update procedure associated with the UE.
[0507] In some embodiments of the present application, the execution of S1201 may be performed when the UE establishes an RRC connection with the base station 1201 and is in a connected state. In other embodiments of the present application, the execution of S1201 may also be performed after the UE enters an idle state.
[0508] Correspondingly, the base station 1201 may determine whether it is necessary to use the LP-WUS solution to perform UE paging according to the obtained DRX assistance information 1202 .
[0509] In the example as shown in Figure 12, the base station 1201 determines to use the LP-WUS scheme for UE paging based on the minimum value of the listening period supported by the AMF carried in the obtained DRX auxiliary information 1202, and / or the minimum value of all listening periods that the core network device (such as AMF) has configured for the UE.
[0510] S1202. Base station 1201 sends a broadcast message to the UE. The broadcast message may include indication information D. The indication information D may be used to instruct the UE to use the LP-WUS scheme for paging monitoring. For example, the indication information D may be used to instruct the UE to monitor WUS. In some embodiments, the indication information D may be included in the first configuration information.
[0511] In this example, when the UE is in the idle state, the base station 1201 can send the broadcast message carrying the indication information D to all UEs within the cell coverage of the base station 1201 in the form of broadcast. In this example, it is taken as an example that the UE is currently located within the coverage of the cell of the base station 1201.
[0512] Combined with the description of the indication information B in Figure 10. In this example, the specific implementation of the indication information D may also have different forms.
[0513] In some implementations, the indication information D may correspond to a preset second field. For example, when the second field is configured as a first value (such as 1), it indicates that the LP-WUS solution is used.
[0514] In some other implementations, the indication information D may correspond to at least part of the LP-WUS configuration information. The LP-WUS configuration information may include at least one of the following: the time-frequency position corresponding to the WUS, the coding information corresponding to the WUS, and the signal strength condition. Thus, when base station 1201 determines to use the LP-WUS scheme for UE paging, it may include the LP-WUS configuration information in a broadcast message.
[0515] Thus, the UE within the coverage of the base station 1201 can obtain the indication information D through the broadcast message. Correspondingly, the UE can determine to use the LP-WUS solution to perform paging monitoring based on the received indication information D.
[0516] Exemplarily, the solution may include:
[0517] S1203: The UE starts the LR and monitors the WUS. In this way, the UE can start the MR when the LR receives the WUS later.
[0518] After that, when the base station 1201 receives a paging message from the core network device, it can page the UE through the LP-WUS solution. Exemplarily, the solution may include:
[0519] S1204 . The core network device sends a paging message 1203 to the base station 1301 .
[0520] S1205. The base station 1201 sends LP wake-up information 1204 to the UE.
[0521] S1206: The UE starts the MR and monitors the paging message.
[0522] S1207. The base station 1201 sends paging scheduling PDCCH information 1205 to the UE.
[0523] S1208. The UE establishes an RRC connection with the base station 1201.
[0524] It is understood that the execution process of S1203 to S1208 can be implemented by referring to the solution for using the LP-WUS solution for UE paging in the aforementioned embodiment, for example, referring to the execution process of S1004 to S1009 in FIG10 .
[0525] It should be noted that, in some embodiments, before executing S1203, the UE may also determine, based on the signal strength condition carried in the broadcast message, that the signal strength condition is met and then execute S1203.
[0526] In the solution provided in FIG12 above, the base station 1201 determines that the LP-WUS solution needs to be used to perform paging on the UE. In other embodiments, as shown in FIG13, a solution implementation is provided in which the access network device determines not to use the LP-WUS solution to perform paging on the UE.
[0527] Exemplarily, as shown in FIG13 , the solution may include:
[0528] S1301. A core network device sends DRX assistance information 1302 to a base station 1301. In the embodiment of the present application, the DRX assistance information 1302 may be included in the second DRX assistance information.
[0529] The execution of the above S1301 may refer to S1201 in FIG. 12 .

In some embodiments, the indication information E may be included in the first configuration information.
[0531] 11 , in some implementations of this example, the broadcast message carrying the indication information E may include: in the broadcast message, the second field is configured as the second value, thereby indicating that the LP-WUS solution is not used.
[0532] In some other implementations, the broadcast message may carry the indication information E by not carrying the LP-WUS configuration information in the broadcast message.
[0533] S1303: The UE starts the MR and monitors the paging message.
[0534] In this way, the UE can monitor the paging message directly through the activated MR without using the LP-WUS solution.
[0535] Exemplarily, the solution may further include:

[0540] Therefore, through the solution provided in Figures 12 and 13, when the UE enters the idle state from the connected state, it can use the LP-WUS solution to monitor the paging message under the instruction of the network (such as the access network device), or it can not use the LP-WUS solution to monitor the paging message.
[0541] Among them, the access network device can determine whether it is necessary to use the LP-WUS solution to page the UE based on the DRX auxiliary information (such as DRX auxiliary information 1202 or DRX auxiliary information 1302) obtained from the core network device (such as AMF).
[0542] It should be pointed out that, in combination with Figures 12 and 13, the base station configures the UE whether to use the LP-WUS scheme in the form of broadcasting. In the scheme implementation shown in Figure 10 or 11, when the UE switches from a connected state to an inactive state, the base station can also use the example shown in Figure 12 or 13 to send the relevant configuration of whether to use the LP-WUS scheme to the UE in the form of broadcasting.
[0543] Therefore, through the detailed description of the above embodiments, the UE and network equipment (such as access network equipment and / or core network equipment) can reasonably and flexibly determine whether to use the LP-WUS solution to paging the UE.
[0544] In some embodiments of the present application, both the above-mentioned indication information B and indication information D can instruct the UE to monitor the WUS. The indication information B and indication information D can be the same or have different implementation forms. In some description forms, both indication information B and indication information D can be included in the second indication information.
[0545] Indication information C is similar to indication information E.
