[0001] The present application claims priority to the Chinese patent application No. 202411093212.9, filed on August 8, 2024, entitled "Information processing method, communication apparatus, storage medium and program product", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to an information processing method, a communication apparatus, a storage medium and a program product. BACKGROUND

[0003] In a new radio (NR) system, a network device can periodically broadcast a system information block (SIB) 1 to provide some necessary system information for a terminal, such as information related to cell access and information related to cell selection.

[0004] At present, in order to achieve energy saving, the network device can not periodically broadcast the SIB1. In this case, the terminal can not receive the SIB1. SUMMARY

[0005] The present application provides an information processing method, a communication apparatus, a storage medium and a program product, which are used to solve the problem that the terminal cannot receive the SIB1 in the prior art.

[0006] In a first aspect, the present application provides an information processing method applied to a terminal, comprising: obtaining first information, wherein the first information is used to indicate configuration information of a first wake-up signal (WUS) obtained by the terminal, and the first WUS is used to request a first system information block (SIB) 1; and obtaining the configuration information of the first WUS based on the first information.

[0007] In the method, the first information can be obtained by the terminal from a first communication apparatus.

[0008] The terminal can be a terminal device as a finished product, such as a complete mobile phone; the terminal can also be a device (for example, a chip, a chip system, a communication module, or a modem, a component, or a circuit) in the terminal device, which can be installed in the finished product terminal; the terminal can also be a device that can be matched with the terminal device, and can also be a logic module or software that can realize all or part of the functions of the terminal device. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices.

[0009] The first communication apparatus can be a network device as a final product, such as a base station; the first communication apparatus can also be an apparatus (for example, a chip, a chip system, a communication module, or a modem, a component, or a circuit) in a network device, which can be installed in a final product network device; the first communication apparatus can also be an apparatus that can be used in matching with a network device, and can also be a logic module or software that can realize all or part of the functions of a network device. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices.

[0010] As an example, the configuration information of the first WUS can be the configuration information of the updated WUS.

[0011] In the method, the terminal can obtain the configuration information of the updated WUS, and subsequently, the terminal can send a WUS to the first communication apparatus based on the configuration information of the updated WUS to request a SIB1, so as to avoid the problem that the terminal cannot receive the SIB1 due to the terminal not receiving the configuration information of the updated WUS.

[0012] In some possible implementation manners, the obtaining the first information includes: receiving a short message, the short message indicating the first information.

[0013] In the implementation manner, when the first information is indicated by the short message, the short message can be received by the terminal in the connected state or the terminal in the non-connected state, and then the configuration information of the first WUS is obtained based on the first information, which is beneficial to guarantee the reliability of the terminal in the connected state or the terminal in the non-connected state receiving the first information.

[0014] In some possible implementation manners, the short message contains a first bit, and the first information is used to indicate whether the configuration information of the first wake-up signal WUS obtained by the terminal includes: the first bit indicating whether the configuration information of the second WUS is updated.

[0015] In the implementation manner, the configuration information of the second WUS can be the configuration information of the WUS before the update.

[0016] In the implementation manner, whether the configuration information of the second WUS is updated can be indicated by the value of the first bit. For example, when the value of the first bit is 1, it can be indicated that the configuration information of the second WUS is updated; when the value of the first bit is 0, it can be indicated that the configuration information of the second WUS is not updated. For another example, when the value of the first bit is 0, it can be indicated that the configuration information of the second WUS is updated; when the value of the first bit is 1, it can be indicated that the configuration information of the second WUS is not updated.

[0017] In the implementation, the first bit in the short message is used to indicate whether the configuration information of the second WUS is updated, so that no additional information is needed to indicate the update, thereby saving the transmission overhead of the system.

[0018] In some possible implementations, the first bit is any bit or the first bit in the short message except the first four bits.

[0019] In the implementation, any bit in the short message except the first four bits is a remaining bit in the short message. When the remaining bit in the short message is used to indicate whether the configuration information of the second WUS is updated, the confusion can be avoided, thereby ensuring the accuracy of the terminal in determining whether the configuration information of the second WUS is updated.

[0020] In the implementation, the first bit in the short message can also be used to indicate that the system information is updated. By multiplexing the first bit in the short message, the transmission overhead of the system can be saved.

[0021] In some possible implementations, the obtaining, based on the first information, of the configuration information of the first WUS includes: in a case where the first bit indicates that the configuration information of the second WUS is updated, receiving the configuration information of the first WUS.

[0022] In the implementation, the configuration information of the first WUS can be actively sent by the first communication device.

[0023] Optionally, after the first communication device sends the short message to the terminal, the first communication device can send the configuration information of the first WUS to the terminal. Correspondingly, the terminal can receive the configuration information of the first WUS.

[0024] In the implementation, the terminal can receive the configuration information of the first WUS in a case where the configuration information of the second WUS is updated. Subsequently, the terminal can request the SIB1 according to the configuration information of the first WUS, so that the terminal can avoid failing to receive the SIB1.

[0025] In some possible implementations, the first information is used to instruct the terminal to obtain the configuration information of the first wake-up signal (WUS), and the first information indicates the validity time of the configuration information of the second WUS.

[0026] In the implementation manner, the terminal can determine whether the configuration information of the second WUS is expired based on the valid time of the configuration information of the second WUS, or in other words, the terminal can determine whether the configuration information of the second WUS is updated based on the valid time of the configuration information of the second WUS. In this way, the terminal can not send the second WUS to the first communication device in the case that the valid time of the configuration information of the second WUS is expired, thereby avoiding the problem of wasting some unnecessary resources.

[0027] In some possible implementation manners, the obtaining the configuration information of the first WUS based on the first information comprises: in the case that it is determined based on the first information that the valid time of the configuration information of the second WUS is about to expire, sending a second WUS based on the configuration information of the second WUS, the second WUS being used for requesting a second SIB1; and receiving the second SIB1, the second SIB1 indicating the configuration information of the first WUS.

[0028] In the implementation manner, the terminal can request the second SIB1 through the second WUS in the case that the valid time of the configuration information of the second WUS is about to expire, so that the terminal can obtain the updated configuration information of the WUS based on the second SIB1, thereby avoiding the problem that the terminal cannot receive the SIB1 due to the expiration of the valid time of the configuration information of the second WUS.

[0029] In some possible implementation manners, the method further comprises: sending the first WUS based on the configuration information of the first WUS; and receiving the first SIB1.

[0030] In the implementation manner, the configuration information of the first WUS can comprise a sending condition of the first WUS. The terminal can determine whether to send the first WUS to the first communication device based on the sending condition of the first WUS. In the case that the sending condition of the first WUS is met, the terminal can send the first WUS to the first communication device.

[0031] In the implementation manner, the configuration information of the first WUS can be the updated configuration information of the WUS. The terminal requests the SIB1 based on the updated configuration information of the WUS, which is beneficial to guarantee the reliability of the terminal in obtaining the SIB1.

[0032] In some possible implementation manners, the method further comprises: obtaining second information, the second information indicating a first time window, the first time window being used for transmitting the first SIB1.

[0033] The receiving the first SIB1 comprises: receiving the first SIB1 in the first time window.

[0034] In this implementation, the terminal can receive the first SIB1 in the first time window instead of directly receiving the first SIB1, which can reduce the time length for the terminal to receive the first SIB1 and help reduce the transmission overhead of the first communication device when sending the first SIB1.

[0035] In some possible implementation, the first information is sent by the first communication device, the first communication device is in a state of on-demand broadcasting of the SIB1, the first communication device does not periodically broadcast the SIB1, or the first communication device is in an energy saving state.

[0036] This implementation can be applied to a scenario where the terminal camps in the coverage of the first communication device and the state of the first communication device broadcasting the SIB1 changes.

[0037] In this scenario, the configuration information of the first WUS can be the configuration information of the WUS before the update or the configuration information of the WUS that has not been updated.

[0038] In this implementation, the first communication device can also send the configuration information of the first WUS to the terminal in the case where the state of the first communication device broadcasting the SIB1 changes. This can avoid the problem that the terminal cannot receive the configuration information of the first WUS when the state of the first communication device broadcasting the SIB1 changes, and the terminal cannot receive the SIB1.

[0039] In some possible implementation, the first information indicates one or more of the following information: the first communication device enters a state of on-demand broadcasting of a system information block (SIB1), the first communication device no longer periodically broadcasts the SIB1, or the first communication device enters an energy saving state.

[0040] In this implementation, the terminal can determine that the state of the first communication device broadcasting the SIB1 changes based on the first information, so that the terminal determines that the configuration information of the first WUS can be received, which helps to ensure the reliability of the terminal receiving the configuration information of the first WUS.

[0041] Optionally, this implementation can also be applied to a scenario where a terminal in a connected state performs cell switching.

[0042] In some possible implementation, the first information further indicates that a communication device accessed by the terminal is switched from a second communication device to the first communication device. The method further includes: accessing the first communication device based on the first information.

[0043] In this implementation, the second communication device is a communication device currently accessed by the terminal.

[0044] In this implementation, the terminal can determine the state of the first communication device broadcasting SIB1 based on the first information, and then access the first communication device based on the state of the first communication device broadcasting SIB1, thereby avoiding the situation that the terminal cannot access the first communication device, and facilitating to ensure the reliability of the terminal accessing the first communication device.

[0045] In some possible implementation, the first information further indicates SIB1 of the first communication device. The accessing the first communication device based on the first information comprises accessing the first communication device based on the SIB1 of the first communication device.

[0046] In this implementation, in the case that the first communication device enters the state of broadcasting SIB1 on demand, or the first communication device no longer periodically broadcasts SIB1, or the first communication device enters the energy saving state, the terminal can access the first communication device based on the SIB1 of the first communication device, thereby facilitating to ensure the reliability of the terminal accessing the first communication device.

[0047] In a second aspect, the present application provides an information processing method, which comprises: obtaining third information, the third information indicating one or more of the following information: the first communication device entering the state of broadcasting system information block (SIB1) on demand, the first communication device no longer periodically broadcasting the SIB1, or the first communication device entering the energy saving state; obtaining configuration information of WUS, the configuration information of WUS containing the valid time of the configuration information of WUS; sending WUS based on the configuration information of WUS, the WUS being used for requesting SIB1; and receiving SIB1.

[0048] The method can be applied to the scenario that the state of the first communication device broadcasting SIB1 to which the terminal camps changes.

[0049] In the method, in the case that the state of the first communication device broadcasting SIB1 changes, the first communication device can send the configuration information of WUS to the terminal. In this way, the problem that the terminal cannot receive the configuration information of WUS when the state of the first communication device broadcasting SIB1 changes, and thus the terminal cannot receive SIB1, can be avoided.

[0059] In some possible implementation manners, the first RRC message includes a dedicated SIB request message.

[0121] The technical solutions of the present application can be applied to a fifth generation (5th generation, 5G) communication system, such as a 5G NR communication system, or to various communication systems evolved after 5G, such as future communication network systems. The method provided by the embodiments of the present application can also be applied to a wireless fidelity (wireless WiFi) system, a long range Internet of Things (long range, LoRa) system, or a vehicle Internet of Things system. The method provided by the embodiments of the present application can also be applied to a satellite communication system, or a non-terrestrial network (non-terrestrial networks, NTN) communication system. The satellite communication system can be integrated with the above communication systems, which is not limited in the present application.

[0122] In the following, the embodiments of the present application are described in detail with reference to the drawings.

[0123] To make the present application more comprehensible, first, a communication system applicable to the embodiments of the present application is described in combination with FIG. 1. As shown in FIG. 1, the communication system includes a wireless access network 100. The wireless access network 100 can include at least one network device (for example, 110a and 110b in FIG. 1) and at least one terminal (for example, 120a to 120j in FIG. 1).

[0124] In the communication system, the network device can include a wireless access network (RAN) device, and the terminal can be connected to the wireless access network device in a wireless manner. The wireless access network device is connected to the core network device in a wireless or wired manner. The core network device and the wireless access network device can be independent and different physical devices, or the functions of the core network device and the logical functions of the wireless access network device can be integrated on the same physical device. The terminal and the terminal, and the wireless access network device and the wireless access network device can be connected to each other in a wired or wireless manner. FIG. 1 is only a schematic diagram, and the communication system can also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG. 1.

[0125] The wireless access network device can be a device with wireless transceiving function. The wireless access network device can be a device providing wireless communication function service, which is usually located at the network side, including but not limited to: a next-generation base station (gNodeB, gNB) in a 5G communication system, a base station in a future mobile communication system or an access node in a WiFi system, an evolved node B (eNB) in a long term evolution (LTE) system, a radio network controller (RNC), a home base station (for example, a home evolved NodeB or a home Node B, HNB), a baseband unit (BBU), a transmission reception point (TRP), a transmitting point (TP), etc.

[0126] The radio access network device serves a cell, and a user equipment uses a transmission resource of the cell to communicate with a base station. The cell can be a cell corresponding to the base station. The cell can belong to a macro base station or a base station corresponding to a small cell. The small cell can include a metro cell, a micro cell, a pico cell, a femto cell, and the like.

[0127] The radio access network device can also be a device that plays a base station role in device to device (D2D) communication, vehicle networking communication, unmanned aerial vehicle communication, and machine communication. Optionally, the radio access network device can be a satellite, a macro base station, a micro base station or an indoor station, a relay node or a donor node, a device providing wireless communication services for a user equipment, a wireless controller in a cloud radio access network (CRAN) scenario, a server, a relay station, a vehicle or a vehicle-mounted device, a wearable device, and a network device in a future evolved network, and the like. For example, the radio access network device in vehicle to everything (V2X) technology can be a road side unit (RSU).

[0128] In another possible scenario, a plurality of radio access network devices cooperate to assist a terminal to implement wireless access, and different radio access network devices respectively implement part of the functions of a base station. For example, in the open radio access network (O-RAN) system architecture shown in FIG. 2, a radio access network device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a BBU. The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It can be understood that the radio access network device can be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU can be divided into a network device in the radio access network device, or the CU can be divided into a network device in the core network device, which is not limited here.

[0129] In addition, the O-RAN system architecture can also include an O-RAN intelligent controller (RIC). The RIC includes a near-real-time RIC (near-RT RIC) and a non-real-time RIC (Non-RT RIC). The near-real-time RIC is used for model training and inference. For example, an artificial intelligence (AI) model is trained, and inference is performed using the AI model. The near-real-time RIC can obtain network side and / or terminal side information from a RAN node (such as a CU, a CU-CP, a CU-UP, a DU, and / or a RU) and / or a terminal. The information can be used as training data or inference data. Optionally, the near-real-time RIC can deliver inference results to the RAN node and / or the terminal. Optionally, the CU and the DU, and / or the DU and the RU can interact with the inference results. For example, the near-real-time RIC delivers the inference results to the DU, and the DU sends them to the RU. The near-real-time intelligent management of the RAN is implemented. Through data collection and related operations on the E2 interface, near-real-time control and optimization of modules and resources of the O-RAN are implemented.

[0130] The non-real-time RIC is used for model training and inference. For example, it is used for training an AI model, and inference is performed using the model. The non-real-time RIC can obtain network-side and / or terminal-side information from the RAN node (e.g., CU, CU-CP, CU-UP, DU, and / or RU) and / or the terminal. This information can be used as training data or inference data, and the inference result can be delivered to the RAN node and / or the terminal. Alternatively, the inference result can be exchanged between the CU and the DU, and / or between the DU and the RU, for example, the non-real-time RIC delivers the inference result to the DU, which then sends it to the RU.

[0131] The near-real-time RIC and the non-real-time RIC can also be separately provided as a network element. Alternatively, the near-real-time RIC and the non-real-time RIC can also be part of other devices, for example, the near-real-time RIC is provided in the RAN node (e.g., CU, DU), and the non-real-time RIC is provided in the operation administration and maintenance (OAM) server, the cloud server, the core network device, or other network devices.

[0132] In different systems, the CU (or CU-CP and CU-UP), DU, or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the O-RAN system as shown in FIG. 3, the CU can also be referred to as an O-RAN central unit (O-CU) (or open CU), the DU can also be referred to as an O-RAN distributed unit (O-DU), the CU-CP can also be referred to as an O-RAN central unit control plane (O-CU-CP), the CU-UP can also be referred to as an O-RAN central unit user plane (O-CU-UP), and the RU can also be referred to as an O-RAN radio unit (O-RU).

[0133] Among them, the O-CU is used to implement the radio resource control (RRC) layer, the packet data convergence protocol (PDCP) layer, and the service data adaptation protocol (SDAP) layer in the 3GPP standard and other control functions.

[0134] The O-CU-CP is similar to the CU-CP in the NR system, and is configured to implement the functions of the RRC layer and the control plane functions of the PDCP layer. It belongs to the O-CU.

[0135] The O-CU-UP is similar to the CU-UP in the NR system, and is configured to implement the functions of the SDAP layer and the user plane functions of the PDCP layer. It belongs to the O-CU.

[0136] The O-DU is based on low-layer function splitting, and is configured to implement the radio link control (RLC) layer, the media access control (MAC) layer, and the higher physical layer (Higher PHY) in the 3GPP standard. The higher physical layer functions include one or more of the following: forward error correction (FEC) encoding / decoding, scrambling / descrambling, or modulation / demodulation.

[0137] The O-RU is based on low-layer function splitting, and is configured to implement the lower physical layer (Lower PHY) functions and the radio frequency (RF) functions in the 3GPP standard. The lower physical layer functions include one or more of the following: fast fourier transform (FFT) transform / inverse fast fourier transformation (iFFT) transform, digital beamforming, or extraction and filtering of a physical random access channel (PRACH). It is similar to the transmission reception point (TRP) or the remote radio head (RRH) in the 3GPP, but includes low physical layer functions such as FFT / iFFT or PRACH extraction.

[0138] For the convenience of description, the CU, CU-CP, CU-UP, DU, and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0139] In the embodiments of the present application, the form of the radio access network device is not limited, and the device for implementing the function of the radio access network device can be a radio access network device; or can be a device capable of supporting the radio access network device to implement the function, such as a chip system. The device can be installed in the radio access network device or used with the radio access network device. Hereinafter, the radio access network device will be taken as a base station for example.

[0140] In the present application, the terminal can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., or a device for providing voice or data connectivity to a user, and can also be an Internet of Things device. For example, the terminal device includes a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, the terminal device can be: a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile internet device (MID), a wearable device (such as a smart watch, a smart bracelet, a pedometer, smart glasses, etc.), a vehicle-mounted device (such as a car, a bicycle, an electric vehicle, an airplane, a ship, a train, a high-speed rail, etc.), a satellite terminal, a virtual reality (VR) device, an augmented reality (AR) device, a smart point of sale (POS) machine, a customer-premises equipment (CPE), a light terminal device (light UE), a reduced capability user equipment (REDCAP UE), a wireless terminal in industrial control, a smart home device (such as a refrigerator, a television, an air conditioner, an electric meter, etc.), a smart robot, a mechanical arm, a workshop device, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home, a flight device (such as a smart robot, a hot air balloon, a drone, an airplane), etc. The terminal device can also be a vehicle device, such as a whole vehicle device, a vehicle-mounted module, a vehicle-mounted chip, an on board unit (OBU), or a telematics box (T-BOX), etc. The terminal device can also be other devices with terminal functions, for example, the terminal device can also be a device with terminal function in D2D communication.

[0141] In the embodiments of the present application, the device for implementing the function of the terminal can be a terminal, or a device capable of supporting the terminal to implement the function, such as a chip system, or a communication module, or a modem, etc., which can be installed in the terminal. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices. The embodiments of the present application do not limit the specific technology and specific equipment form adopted by the terminal.

[0142] In the present application, the base station and the terminal can be fixed in position, or can be movable. The base station and the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; and can also be deployed on aircraft, balloons and satellites in the air. The embodiments of the present application do not limit the application scenarios of the base station and the terminal.

[0143] The roles of the base station and the terminal can be relative, for example, the helicopter or the unmanned aerial vehicle 120i in FIG. 1 can be configured as a mobile base station, and for those terminals 120j accessing the wireless access network 100 through 120i, the terminal 120i is a base station; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate through a wireless air interface protocol. Of course, 110a and 120i can also communicate through a base station-to-base station interface protocol, at this time, relative to 110a, 120i is also a base station. Therefore, the base station and the terminal can be collectively referred to as a communication device, and 110a, 110b and 120a-120j in FIG. 1 can be referred to as communication devices with their respective corresponding functions, such as a communication device with a base station function, or a communication device with a terminal function.

[0144] The base station and the terminal, the base station and the base station, and the terminal and the terminal can communicate through a licensed spectrum, or through an unlicensed spectrum, or through both the licensed spectrum and the unlicensed spectrum. The base station and the terminal, and the terminal and the terminal can communicate through a sub-6G (sub 6G) spectrum, or through a spectrum above 6G, or through both the sub-6G spectrum and the spectrum above 6G. The embodiments of the present application do not limit the spectrum resources used between the wireless access network devices and the terminal.

[0145] It should be noted that the network device in the embodiments of the present application can also be referred to as a communication apparatus. The communication apparatus can be a network device (such as a base station) as an end product; the network device can also be a device (for example, a chip, a chip system, a communication module, or a modem, a component, or a circuit) in the network device, which can be installed in the end product network device; the network device can also be a device that can be used in conjunction with the network device, and can also be a logic module or software that can implement all or part of the functions of the network device. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices.

[0146] It should be noted that the terminal in the embodiments of the present application can be a terminal device as an end product, such as a mobile phone complete machine; the terminal device can also be a device (for example, a chip, a chip system, a communication module, or a modem, a component, or a circuit) in the terminal device, which can be installed in the end product terminal; the terminal can also be a device that can be used in conjunction with the terminal device, and can also be a logic module or software that can implement all or part of the functions of the terminal device. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices.

[0147] In a communication system, a network device can periodically broadcast SIB1. SIB1 is a signal that the network device has been broadcasting, and its function is to provide necessary system information for a cell, including information related to cell access and information related to cell selection. The terminal searches for the SSB signal by searching for the frequency point where the synchronization signal and the PBCH block (SSB) are located, and after finding the SSB signal, the cell is found. The terminal can obtain the time-frequency resource information of the PDCCH scheduling SIB1 according to the MIB information carried in the SSB, and the terminal can obtain the information of the PDCCH based on this information. After the terminal obtains the information of the PDCCH, the terminal can obtain the related information of the PDSCH carrying SIB1 scheduled by the PDCCH. Therefore, the terminal can receive SIB1 on the corresponding PDSCH, and obtain the necessary system information.

[0148] In the embodiments of the present application, SIB1 can also be referred to as remaining minimum system information (RMSI).

[0149] In one possible implementation, the terminal needs to acquire the information of SIB1 first. After the terminal acquires the information of SIB1, the terminal keeps the information of SIB1. However, the protocol stipulates that the terminal should delete any stored version of SIB after 3 hours from the time when the terminal successfully confirms the validity of SIB; that is, the validity period of SIB is 3 hours. The protocol can be applicable to any SIB, that is, the validity period of SIB1 is 3 hours. In the implementation, SIB1 is periodically broadcast, so after the SIB1 storage time of the terminal expires, the terminal can automatically reacquire SIB1 from the periodically broadcast SIB1 of the network device.

[0150] In addition, when the system information of the network device changes, the network device sends a broadcast to notify all terminals that the system information has changed. The terminal receives a short message transmission of a paging radio network temporary identifier (P-RNTI) scrambled downlink control information (DCI) to receive an indication of a system information (SI) modification and / or a public warning system (PWS) notification.

[0151] The short message can be transmitted on the PDCCH using P-RNTI scrambling, and a paging message is sent using the short message field in DCI format 1_0.

[0152] There are eight bits in the short message, and four bits have been used.

[0153] The first bit is used to indicate system information change. If the value of the first bit is 1, it can indicate that a modification of the broadcast control channel (BCCH) occurs except for SIB6, SIB7, SIB8, and positioning system information blocks (posSIBs).

[0154] The second bit is used to notify the earthquake and tsunami warning system (ETWS) and the commercial mobile alert system (CMAS). If the value of the second bit is 1, it can indicate one ETWS primary notification and / or one ETWS secondary notification and / or one CMAS notification.

[0155] The third bit is used for stopping paging monitoring, the bit is only used for spectrum channel access operation, and the terminal exists when the number of PDCCH monitoring opportunities (nrofPDCCH-MonitoringOccasionPerSSB-InPO) associated with each SSB is configured. If the value of the third bit is 1, it indicates that the terminal can stop monitoring the PDCCH occasion.

[0156] The fourth bit is used for system information modification. If the value of the fourth bit is 1, it indicates the BCCH modification except SIB6, SIB7, SIB8 and posSIBs. The indication is only applicable to the terminal using the idle state (IDLE) extended discontinuous reception (eDRX) period longer than the BCCH modification period.

[0157] The fifth bit to the eighth bit are idle bits.

[0158] At present, in order to achieve the purpose of energy saving, some network devices can not periodically broadcast SIB1. In this case, when the idle state terminal or the deactivated state terminal needs to obtain SIB1, it can send a wake up signal (WUS) to the network device based on the configuration information of the WUS, and the network device broadcasts SIB1 after receiving the WUS. However, it is found in use that the terminal often cannot receive SIB1.

[0159] It is found through research that the reason why the terminal cannot receive SIB1 is that the idle state terminal or the deactivated state terminal cannot determine whether the configuration information of the WUS is expired. If the configuration information of the WUS is expired, the terminal sends a WUS to the network device based on the configuration information of the WUS, so that the WUS received by the network device is illegal, and the network device will not broadcast SIB based on the WUS, resulting in that the terminal cannot receive SIB1.

[0160] In addition, the method is applicable to the idle state terminal or the deactivated state terminal. For the connected state terminal, there is no solution to obtain SIB1.

[0161] Therefore, the present application provides a technical solution to solve the problem that the terminal cannot receive SIB1 in the prior art.

[0162] In the technical solution of the present application, the terminal can obtain first information, the first information can be used to obtain the configuration information of the first WUS, and the first WUS is used to request the first SIB1; the terminal can obtain the configuration information of the first WUS based on the first information.

[0163] The terminal can be a terminal device as a final product, such as a mobile phone complete machine; the terminal can also be a device (for example, a chip, a chip system, a communication module, or a modem, a component, or a circuit) in the terminal device, which can be installed in the final product terminal; the terminal can also be a device that can be matched with the terminal device, and can also be a logic module or software that can realize all or part of the function of the terminal device. In the embodiment of the application, the chip system can be composed of a chip, or can include a chip and other discrete devices. In the following, the embodiment of the application can be exemplified by the terminal.

[0164] In the technical solution, the first information can be obtained by the terminal from the first communication device.

[0165] The first communication device can be a network device as a final product, such as a base station; the first communication device can also be a device (for example, a chip, a chip system, a communication module, or a modem, a component, or a circuit) in the network device, which can be installed in the final product network device; the first communication device can also be a device that can be matched with the network device, and can also be a logic module or software that can realize all or part of the function of the network device. In the embodiment of the application, the chip system can be composed of a chip, or can include a chip and other discrete devices. In the following, the embodiment of the application can be exemplified by the first communication device.

[0166] As an example, the configuration information of the first WUS can be the configuration information of the updated WUS.

[0167] In the method, the terminal can obtain the configuration information of the updated WUS, and subsequently, the terminal can send the WUS to the first communication device based on the configuration information of the updated WUS to request the SIB1, so as to avoid the problem that the terminal cannot receive the SIB1 due to the fact that the terminal cannot receive the configuration information of the updated WUS.

[0168] In a possible implementation, when the configuration information of the second WUS expires, the first communication device can send the first information to the terminal to indicate that the configuration information of the second WUS is updated.

[0169] The configuration information of the second WUS is the configuration information of the WUS before the update.

[0170] In addition, the first communication device can also send the configuration information of the first WUS to the terminal to provide the terminal with the configuration information of the updated WUS, so as to avoid the case that the SIB1 cannot be subsequently received due to the expiration of the configuration information of the second WUS.

[0171] In another possible implementation, the first information can indicate the validity time of the configuration information of the second WUS.

[0172] In this implementation, the terminal can determine whether the validity time of the configuration information of the second WUS is about to expire based on the first information.

[0173] As an example, assuming that the time interval between the current time and the end time of the validity time of the configuration information of the second WUS is less than or equal to the preset interval, the terminal can determine that the validity time of the configuration information of the second WUS is about to expire.

[0174] In this implementation, in the case where it is determined that the validity time of the configuration information of the second WUS is about to expire, the terminal can send the second WUS to the first communication device based on the configuration information of the second WUS to request the second SIB1. In this way, after receiving the second WUS, the first communication device can send the second SIB1 to the terminal in response to the second WUS, and the second SIB1 can indicate the configuration information of the first WUS.

[0175] In this implementation, the terminal can request the configuration information of the first WUS through the second WUS before the validity time of the configuration information of the second WUS is about to expire, which can avoid the case where the SIB1 cannot be received subsequently due to the expiration of the configuration information of the second WUS.

[0176] In the embodiments of the present application, when the network device does not periodically broadcast the SIB1, it indicates that the network device is in an energy saving state. The energy saving state can also be described as an on-demand SIB1 state, an SIB1 state broadcast on demand, a non-periodic SIB1 state, a non-SIB1 state, etc. In the embodiments of the present application, the network device in the energy saving state can also be referred to as an energy saving base station or an energy saving cell (NES cell), etc. The embodiments of the present application can be applied to a multi-carrier scenario as shown in (a) of FIG. 4 or a single-carrier scenario as shown in (b) of FIG. 4.

[0177] In the multi-carrier scenario as shown in (a) of FIG. 4, an energy saving cell and a cooperating cell can be included. The cooperating cell is a cell with normal functions, and in addition, it is a cell that helps the energy saving cell broadcast the WUS configuration. In this case, the energy saving cell can only send the SSB, which is conducive to the terminal discovering the energy saving cell and measuring the signal quality of the energy saving cell, so that the terminal can determine whether to select / reselect to the energy saving cell and determine whether to send the WUS to trigger the energy saving cell to send the SIB1.

[0178] In the embodiments of the present application, the cooperating cell can also be referred to as an auxiliary cell.

[0179] In the single carrier scenario as shown in (b) of FIG. 4, the energy saving cell can be included without the cooperation cell. The configuration information of the WUS can be broadcasted for the energy saving cell, for example, can be pre-configured or carried in the MIB, in which case the terminal can obtain the WUS configuration information in one cell and trigger the energy saving cell to send the SIB1 by sending the WUS, without the participation of the cooperation cell.

[0180] Next, the present application will further introduce the scheme of the present application in combination with FIG. 5 to FIG. 16.

[0181] FIG. 5 is a flow diagram of an information processing method provided by an embodiment of the present application.

[0182] S501, the terminal obtains first information, the first information being used for indicating the terminal to obtain configuration information of a first WUS, the first WUS being used for requesting a first SIB1.

[0183] In the method, the terminal can be a non-connected state terminal, or can be a connected state terminal.

[0184] Optionally, the first information can be sent by a first communication device. The first communication device can be a network device as shown in any one of FIG. 1 to FIG. 4.

[0185] In the method, the configuration information of the first WUS can include one or more of the following information: a valid time of the configuration information of the first WUS, a root sequence index of a preamble of the first WUS, a time-frequency resource of sending of the first WUS, a sending repetition number of the first WUS, a preamble index of the preamble of the first WUS, a starting index of the preamble of the first WUS (ra-PreambleStartIndex), a mask index of an SSB opportunity used by the first WUS (ra-ssb-OccasionMaskIndex), or, a sending condition of the first WUS.

[0186] The valid time of the configuration information of the first WUS can be used to confirm whether the valid time of the configuration information of the first WUS is expired, or can be used to confirm whether the configuration information of the first WUS is changed. After the terminal receives the time information, the terminal can determine whether the configuration information of the first WUS is expired based on the time information.

[0187] As an example, the valid time of the configuration information of the first WUS can be indicated by an absolute time. For example, the absolute time can be a time interval between a valid starting moment and a valid ending moment of the configuration information of the first WUS.

[0188] In this example, the configuration information of the first WUS can comprise a valid start time and a valid end time of the configuration information of the first WUS.

[0189] As another example, the valid time of the configuration information of the first WUS can be indicated by a valid start time and a duration.

[0190] In this example, the configuration information of the first WUS can comprise a valid start time and a duration of the configuration information of the first WUS.

[0191] As yet another example, the valid time of the configuration information of the first WUS can be indicated by a start system frame number to an end system frame number.

[0192] In this example, the configuration information of the first WUS can comprise a start system frame number and an end system frame number of the configuration information of the first WUS.

[0193] As yet another example, the valid time of the configuration information of the first WUS can be indicated by a start system frame number and a duration.

[0194] In this example, the configuration information of the first WUS can comprise a valid system frame number and a duration of the configuration information of the first WUS.

[0195] Optionally, the duration can be indicated by a number of frames.

[0196] In a possible implementation, the sending condition of the first WUS can be that a reference signal receiving power (RSRP) received by the terminal reaches a preset threshold.

[0197] Optionally, the threshold can be a threshold satisfied for cell reselection.

[0198] In the method, the configuration information of the first WUS can be the configuration information of the updated WUS.

[0199] In the method, the first communication device can be in a state of on-demand broadcasting of SIB1, that is, the first communication device does not periodically broadcast the SIB1, or the first communication device is in an energy saving state.

[0200] The method can be applied in a multi-carrier scenario and a single-carrier scenario. In the multi-carrier scenario, the first communication device can send the configuration information of the WUS to the terminal through another communication device. In the single-carrier scenario, the first communication device does not need to send the configuration information of the WUS to the terminal through another communication device.

[0201] In a possible implementation, the first communication device can send a short message to the terminal, the short message being used to indicate the first information.

[0202] In this implementation, when the first information is indicated by the short message, the terminal in the connected state or the terminal in the non-connected state can receive the short message, and then obtain the configuration information of the first WUS based on the first information, which is beneficial to guarantee the reliability of the terminal in the connected state or the terminal in the non-connected state receiving the first information.

[0203] The first bit in the short message can be included.

[0204] In this implementation, the first information used to indicate the terminal to obtain the configuration information of the first WUS can include that the first bit can be used to indicate whether the configuration information of the second WUS is updated. The configuration information of the second WUS can be the configuration information of the WUS before the update.

[0205] In this implementation, whether the configuration information of the second WUS is updated can be indicated by the value of the first bit. For example, when the value of the first bit is 1, it can be indicated that the configuration information of the second WUS is updated; when the value of the first bit is 0, it can be indicated that the configuration information of the second WUS is not updated. For another example, when the value of the first bit is 0, it can be indicated that the configuration information of the second WUS is updated; when the value of the first bit is 1, it can be indicated that the configuration information of the second WUS is not updated.

[0206] Optionally, in some embodiments, when the configuration information of the second WUS is not updated, the first communication device can not indicate, i.e., can not indicate by the first bit.

[0207] In this method, the first communication device can previously send the configuration information of the second WUS to the terminal. The information included in the configuration information of the second WUS can be similar to the information included in the aforementioned configuration information of the first WUS, which will not be described herein again.

[0208] Whether the configuration information of the second WUS is updated is indicated by the first bit in the short message, so that it is not necessary to indicate by additional information, which is beneficial to save the transmission overhead of the system.

[0209] As an example, the first bit can be any one bit in the short message except the first four bits.

[0210] In this example, any bit in the short message except the first four bits is a remaining bit in the short message. By indicating whether the configuration information of the second WUS is updated through the remaining bit in the short message, confusion can be avoided, and the accuracy of the terminal determining whether the configuration information of the second WUS is updated can be ensured.

[0211] As another example, the first bit can be the first bit in the short message.

[0212] In this example, the first bit in the short message can also be used to indicate that the system information is updated. For example, the configuration information of the WUS is carried in the SIB1. By using the first bit to indicate that the system information is updated, the terminal can reacquire the system information, and then acquire the updated configuration information of the WUS in the existing system information.

[0213] In this example, by multiplexing the first bit in the short message, the transmission overhead of the system can be saved.

[0214] In another possible implementation, the first information used to instruct the terminal to acquire the configuration information of the first WUS can include that the first information can indicate the validity time of the configuration information of the second WUS.

[0215] In this implementation, the configuration information of the second WUS can be the configuration information of the WUS before the update.

[0216] As an example, the first information can include the configuration information of the second WUS, and the configuration information of the second WUS includes the validity time of the configuration information of the second WUS.

[0217] Optionally, the indication manner of the validity time of the configuration information of the second WUS is similar to the validity time of the configuration information of the first WUS, which will not be described here.

[0218] In this implementation, the terminal can determine whether the configuration information of the second WUS is expired based on the validity time of the configuration information of the second WUS, or in other words, the terminal can determine whether the configuration information of the second WUS is updated based on the validity time of the configuration information of the second WUS. In this way, the terminal can not send the second WUS to the first communication device in the case that the validity time of the configuration information of the second WUS expires, avoiding the problem of wasting some unnecessary resources.

[0219] S502, the terminal acquires the configuration information of the first WUS based on the first information.

[0220] In a possible implementation, the first communication device can send a short message to the terminal, and the short message is used to indicate the first information.

[0221] The short message can include a first bit, which can indicate whether the configuration information of the second WUS is updated. The configuration information of the second WUS can be the configuration information of the WUS before the update.

[0222] In the implementation, when the first bit indicates that the configuration information of the second WUS is updated, the terminal can receive the configuration information of the first WUS.

[0223] In the implementation, the configuration information of the first WUS can be actively sent by the first communication device.

[0224] Optionally, after the first communication device sends the short message to the terminal, the first communication device can send the configuration information of the first WUS to the terminal. Correspondingly, the terminal can receive the configuration information of the first WUS.

[0225] In the implementation, the terminal can receive the configuration information of the first WUS when the configuration information of the second WUS is updated. Subsequently, the terminal can request the SIB1 according to the configuration information of the first WUS, so as to avoid the situation that the terminal cannot receive the SIB1.

[0226] In another possible implementation, the first information indicates the validity time of the configuration information of the second WUS.

[0227] In the implementation, when the terminal determines that the validity time of the configuration information of the second WUS is about to expire based on the first information, the terminal can send the second WUS to the first communication device based on the configuration information of the second WUS, and the second WUS can be used to request the second SIB1. After receiving the second WUS, the first communication device can send the second SIB1 to the terminal in response to the second WUS, and the second SIB1 can indicate the configuration information of the first WUS.

[0228] Optionally, the configuration information of the first WUS can be carried in the second SIB1.

[0229] Optionally, the configuration information of the first WUS can also be carried in other SIB information or other messages, which are not limited in the application.

[0230] In the implementation, when the validity time of the configuration information of the second WUS is about to expire, the terminal can request the second SIB1 through the second WUS, so that the terminal can obtain the updated configuration information of the WUS based on the second SIB1, and avoid the problem that the terminal cannot receive the SIB1 due to the expiration of the validity time of the configuration information of the second WUS.

[0231] Optionally, after receiving the configuration information of the first WUS, the terminal can send the first WUS to the first communication device based on the configuration information of the first WUS, the first WUS being used to request the first SIB1. Correspondingly, after receiving the first WUS, the first communication device can send the first SIB1 to the terminal in response to the first WUS. Correspondingly, the terminal receives the first SIB1.

[0232] In the method, the configuration information of the first WUS can include a transmission condition of the first WUS. The terminal can determine whether to send the first WUS to the first communication device based on the transmission condition of the first WUS. In the case where the transmission condition of the first WUS is met, the terminal can send the first WUS to the first communication device.

[0233] In the implementation, the configuration information of the first WUS can be the configuration information of the updated WUS. The terminal requests the SIB1 based on the configuration information of the updated WUS, which is conducive to ensuring the reliability of the terminal in acquiring the SIB1.

[0234] Optionally, the first communication device can further send second information to the terminal, the second information being used to indicate a first time window, the first time window being used to transmit the first SIB1. In this way, after receiving the second information, the terminal can receive the first SIB1 within the first time window.

[0235] As an example, the first time window can be indicated by an absolute time. For example, the absolute time can be a time interval between a start time and an end time of the first time window.

[0236] As another example, the first time window can be indicated by a valid start time and a duration.

[0237] As yet another example, the first time window can be indicated by a start system frame number and an end system frame number.

[0238] As yet another example, the first time window can be indicated by a start system frame number and a duration. Optionally, the duration can be indicated by a frame number.

[0239] In a possible implementation, the first time window can also be described by other names, such as a transmission duration, a transmission length, etc., which are not limited in the present application.

[0240] In a possible implementation, in some embodiments, the second information can be the configuration information of the WUS. For example, the second information can be the configuration information of the first WUS. As another example, the second information can be the configuration information of the second WUS.

[0241] In a possible implementation, in a multi-carrier scenario, the first communication apparatus can further send, through another communication apparatus, the second information to the terminal.

[0242] In a possible implementation, in some embodiments, the second information can be carried in a random access response (RAR) message.

[0243] In this implementation, the terminal can receive the first SIB1 within the first time window instead of receiving the first SIB1 directly, which can reduce the time length for the terminal to receive the first SIB1, reduce power consumption of the terminal, and facilitate reduction of transmission overhead of the first communication apparatus when sending the first SIB1.

[0244] Optionally, in some scenarios, the terminal can be camped in the coverage of the first communication apparatus, and the state of the first communication apparatus broadcasting the SIB1 can change, for example, the first communication apparatus can switch from periodically broadcasting the SIB1 to on-demand broadcasting of the SIB1.

[0245] In this scenario, the configuration information of the first WUS can be the configuration information of the WUS before the update or the configuration information of the WUS that has not been updated.

[0246] In this scenario, when the first communication apparatus decides to switch from periodically broadcasting the SIB1 to on-demand broadcasting of the SIB1, the first communication apparatus can send a short message to the terminal, where the short message is used to indicate that the system message is updated.

[0247] In this scenario, in the case where the state of the first communication apparatus broadcasting the SIB1 changes, the first communication apparatus can send the configuration information of the first WUS to the terminal. In this way, the problem that the terminal cannot receive the configuration information of the first WUS when the state of the first communication apparatus broadcasting the SIB1 changes can be avoided, and the terminal cannot receive the SIB1.

[0248] In a possible implementation, the first communication apparatus can further send first information to the terminal, where the first information indicates one or more of the following information: the first communication apparatus enters the state of on-demand broadcasting of the SIB1, the first communication apparatus no longer periodically broadcasts the SIB1, or the first communication apparatus enters the energy saving state.

[0249] In this method, after the terminal receives the first information, the terminal can determine, based on the first information, that the state of the first communication apparatus broadcasting the SIB1 changes, so that the terminal determines that the configuration information of the first WUS can be received, which facilitates guarantee of the reliability of the terminal receiving the configuration information of the first WUS.

[0250] In the method, after the first communication device sends the first information, the first communication device can further send configuration information of the first WUS to the terminal. Correspondingly, the terminal can receive the configuration information of the first WUS.

[0251] Optionally, the configuration information of the first WUS can be broadcast by the first communication device, or can be carried in the first information or a system message.

[0252] Optionally, in another scenario, the terminal in the connected state can switch from a second communication device to a first communication device. The second communication device is a communication device currently accessed by the terminal, and the first communication device is a communication device to be accessed by the terminal, or in other words, the first communication device can be a first communication device to which the terminal wants to switch.

[0253] In this scenario, the terminal in the connected state can obtain the first information, and the first information can indicate that the communication device accessed by the terminal is switched from the second communication device to the first communication device. In this way, the terminal can determine that the switching can be performed based on the first information, and then access the first communication device.

[0254] In the method, the first information can further indicate one or more of the following information: the first communication device enters a state of on-demand broadcasting of SIB1, the first communication device no longer periodically broadcasts SIB1, or the first communication device enters an energy saving state.

[0255] In the method, the terminal can determine the state of broadcasting SIB1 by the first communication device based on the first information, and then access the first communication device based on the state of broadcasting SIB1 by the first communication device, so as to avoid a situation that the terminal cannot access the first communication device.

[0256] Optionally, the first information can further indicate SIB1 of the first communication device. In this way, in the case that the first communication device enters a state of on-demand broadcasting of SIB1, or the first communication device no longer periodically broadcasts SIB1, or the first communication device enters an energy saving state, the terminal can access the first communication device based on the SIB1 of the first communication device, which is beneficial to guarantee the reliability of the terminal accessing the first communication device.

[0257] Optionally, the first information can be carried in an RRC reconfiguration (RRCReconfiguration) message. The RRC reconfiguration message can be sent by the second communication device to the terminal, and the second communication device can previously obtain the state of broadcasting SIB1 by the first communication device and the SIB1 of the first communication device from the first communication device.

[0258] Next, the present application will introduce a method for a terminal to obtain configuration information of a first WUS by taking the configuration information of the first WUS as updated configuration information of a WUS in a multi-carrier scenario.

[0259] In a possible implementation, when the first communication device indicates that the configuration information of the WUS is updated through a short message, the method in which the terminal acquires the configuration information of the first WUS can be as shown in FIG. 6.

[0265] In the method, the terminal can be camped on the other communication device.

[0266] In the method, the second WUS can be used to request the second SIB1.

[0267] In a possible implementation, the other communication device can send the configuration information of the second WUS to the terminal in a broadcast manner.

[0268] In a possible implementation, the configuration information of the second WUS can include a transmission condition of the second WUS.

[0269] The terminal can determine whether the transmission condition of the second WUS is met, and in the case where the transmission condition of the second WUS is met, the terminal can send the second WUS to the first communication device. Correspondingly, after receiving the second WUS, the first communication device can send the second SIB1 to the terminal in response to the second WUS.

[0270] In a possible implementation, before the first communication device sends the second SIB1 to the terminal, the first communication device can also send a RAR message to the terminal, where the RAR message is used to indicate that the first communication device determines to send the second SIB1 to the terminal.

[0271] In a possible implementation, the first communication device can also send information indicating a second time window to the terminal, where the second time window is used for transmission of the second SIB1. In this way, after receiving the information, the terminal can receive the second SIB1 in the second time window.

[0272] Correspondingly, the terminal can camp on the first communication device based on the received second SIB1.

[0273] S603, the first communication device sends a short message to the terminal, the short message containing a first bit indicating whether the configuration information of the second WUS is updated. Correspondingly, the terminal receives the short message.

[0274] In the method, whether the configuration information of the second WUS is updated can be indicated by the value of the first bit. For example, when the value of the first bit is 1, it can be indicated that the configuration information of the second WUS is updated; when the value of the first bit is 0, it can be indicated that the configuration information of the second WUS is not updated. For example, when the value of the first bit is 0, it can be indicated that the configuration information of the second WUS is updated; when the value of the first bit is 1, it can be indicated that the configuration information of the second WUS is not updated.

[0275] Optionally, in some embodiments, when the configuration information of the second WUS is not updated, the first communication device can not indicate, i.e. can not indicate through the first bit.

[0276] Optionally, the first bit can be any bit or the first bit in the short message except the first four bits.

[0277] In the method, when the first bit in the short message indicates that the configuration information of the second WUS is updated, the short message can indicate the first information, the first information being used to instruct the terminal to acquire the configuration information of the first WUS. The configuration information of the first WUS can be the updated WUS configuration information.

[0278] S604, when the first bit indicates that the configuration information of the second WUS is updated, the first communication device sends the configuration information of the first WUS to the terminal. Correspondingly, the terminal receives the configuration information of the first WUS.

[0279] Optionally, when the terminal camps on other communication devices, the first communication device can send the configuration information of the first WUS to the terminal through the other communication devices.

[0280] Optionally, when the terminal camps on the first communication device, the first communication device can not need to send the configuration information of the first WUS to the terminal through other communication devices, but directly send the configuration information of the first WUS to the terminal.

[0281] Optionally, the configuration information of the first WUS can be carried in the SIB1, or can be carried in other SIBs, or can be carried in other information, which is not limited in the application.

[0282] In a possible implementation, the first communication apparatus can not send the configuration information of the first WUS to the terminal, but can send the configuration information of the partial WUS to the terminal, the configuration information of the partial WUS being the part of the configuration information of the first WUS that is changed compared with the configuration information of the second WUS, which is beneficial to saving system transmission overhead.

[0283] In another possible implementation, when the terminal determines whether the configuration information of the WUS is expired or updated based on the validity time of the configuration information of the WUS, the method in which the terminal obtains the configuration information of the first WUS can be as shown in FIG. 7.

[0284] S701, the first communication apparatus sends the configuration information of the second WUS to another communication apparatus. Correspondingly, the other communication apparatus receives the configuration information of the second WUS.

[0285] In the method, the first communication apparatus is in a state of on-demand broadcasting of the SIB1, or the first communication apparatus does not periodically broadcast the SIB1, or the first communication apparatus is in an energy saving state.

[0286] In the method, the other communication apparatus can be a cooperating cell of the first communication apparatus.

[0287] The configuration information of the second WUS can be the configuration information of the WUS before the update.

[0288] S702, the other communication apparatus sends the configuration information of the second WUS to the terminal. Correspondingly, the terminal receives the configuration information of the second WUS.

[0289] In the method, the terminal can be camped on the other communication apparatus.

[0290] In the method, the second WUS can be used to request the second SIB1.

[0291] Optionally, the other communication apparatus can send the configuration information of the second WUS to the terminal in a broadcast manner.

[0292] Optionally, the configuration information of the second WUS can include a sending condition of the second WUS.

[0293] The terminal can determine whether the sending condition of the second WUS is met, and in the case where the sending condition of the second WUS is met, the terminal can send the second WUS to the first communication apparatus. Correspondingly, after receiving the second WUS, the first communication apparatus can send the second SIB1 to the terminal in response to the second WUS.

[0294] Optionally, before the first communication device sends the second SIB1 to the terminal, the first communication device can also send a RAR message to the terminal, where the RAR message is used to indicate that the first communication device determines to send the second SIB1 to the terminal.

[0295] Optionally, the first communication device can also send information used to indicate a second time window to the terminal, where the second time window is used to transmit the second SIB1. In this way, after the terminal receives the information, the terminal can receive the second SIB1 within the second time window.

[0296] Correspondingly, the terminal can camp on the first communication device based on the received second SIB1.

[0297] S703, the first communication device sends first information to the terminal, where the first information indicates a valid time of configuration information of the second WUS. Correspondingly, the terminal receives the first information.

[0298] Optionally, the first information can be the configuration information of the second WUS, and the configuration information of the second WUS can carry the valid time of the configuration information of the second WUS.

[0299] The valid time of the configuration information of the second WUS can refer to the description of the valid time of the configuration information of the first WUS in the foregoing embodiments, which will not be described here again.

[0300] S704, when the terminal determines that the valid time of the configuration information of the second WUS is about to expire, the terminal sends a second WUS to the first communication device based on the configuration information of the second WUS, where the second WUS is used to request the second SIB1. Correspondingly, the first communication device receives the second WUS.

[0301] As an example, assuming that a time interval between a current time and an end time of the valid time of the configuration information of the second WUS is less than or equal to a preset interval, the terminal can determine that the valid time of the configuration information of the second WUS is about to expire.

[0302] S705, the first communication device sends the second SIB1 to the terminal, where the second SIB1 indicates the configuration information of the first WUS. Correspondingly, the terminal receives the configuration information of the first WUS.

[0303] Optionally, in some embodiments, the first communication device can not need to send the configuration information of the first WUS to the terminal, but can send part of the configuration information of the WUS to the terminal, where the part of the configuration information of the WUS can be the part of the configuration information of the first WUS that is changed compared with the configuration information of the second WUS, which is beneficial to saving system transmission overhead.

[0304] Optionally, the method shown in FIG. 7 can also be applicable to the case where the configuration information of the WUS is updated.

[0305] Optionally, the method shown in Fig. 6 or Fig. 7 can also be applied to a single carrier scenario. The difference is that, in the single carrier scenario, the first communication device does not need to send the configuration information of the WUS to the terminal through the other communication device.

[0306] Optionally, in some scenarios, the first communication device in which the terminal is located can be switched from a state of periodically broadcasting SIB1 to a state of on-demand broadcasting SIB1. In this case, the method for the terminal to obtain the configuration information of the WUS can be as shown in Fig. 8.

[0307] S801, the first communication device decides to enter a state of on-demand broadcasting SIB1.

[0308] In the method, the first communication device is the communication device in which the terminal is located. The terminal can be a terminal in an unconnected state or a terminal in a connected state.

[0309] Optionally, in the case where the load of the first communication device is relatively small, the first communication device has a demand for reducing power consumption, and in this case, the first communication device can decide to enter the state of on-demand broadcasting SIB1.

[0310] S802, the first communication device sends a short message to the terminal, and the short message is used to indicate that the system information is updated. Correspondingly, the terminal receives the short message.

[0311] In the method, the short message can indicate that the system information is updated through a first bit.

[0312] Optionally, the short message can also be used to indicate that the configuration information of the WUS is changed.

[0313] As an example, the short message can indicate that the configuration information of the WUS is changed through a first bit. The first bit can be any bit or the first bit in the short message except for the first four bits.

[0314] S803, the first communication device sends third information to the terminal, and the third information indicates one or more of the following information: the first communication device enters the state of on-demand broadcasting SIB1, the first communication device no longer periodically broadcasts SIB1, or the first communication device enters an energy saving state. Correspondingly, the terminal receives the third information.

[0315] In the method, the third information can be used by the terminal to obtain the configuration information of the WUS.

[0316] Optionally, the third information can be a condition for the terminal to obtain the configuration information of the WUS. For example, after the terminal receives the third information, the terminal is instructed to obtain the configuration information of the WUS.

[0317] S804, the first communication device sends configuration information of the WUS to the terminal, and the configuration information of the WUS can include a valid time of the configuration information of the WUS. Correspondingly, the terminal receives the configuration information of the WUS.

[0318] In the method, the information included in the configuration information of the WUS can refer to the content in the configuration information of the first WUS in the foregoing embodiments, which will not be described herein.

[0319] Optionally, the first communication device can send the configuration information of the WUS to the terminal in a broadcast manner. Correspondingly, the terminal can receive the configuration information of the WUS broadcast by the first communication device.

[0320] Optionally, the configuration information of the WUS can be broadcast in SIB1, and the SIB1 can be SIB1 periodically broadcast before the first communication device enters the energy saving state. For example, the configuration information of the WUS can be carried in random access channel (RACH) configuration in the SIB1.

[0321] Optionally, the configuration information of the WUS can also be carried in other SIBs or other messages.

[0322] S805, the terminal sends a WUS to the first communication device based on the configuration information of the WUS, and the WUS is used to request SIB1. Correspondingly, the first communication device receives the WUS.

[0323] Optionally, the configuration information of the WUS can include a sending condition of the WUS. When the terminal determines that the sending condition of the WUS is met, the terminal sends the WUS to the first communication device based on the configuration information of the WUS.

[0324] As an example, it is assumed that the sending condition of the WUS is that the RSRP received by the terminal reaches a preset threshold. When the RSRP received by the terminal reaches the preset threshold, the terminal can send the WUS to the first communication device based on the configuration information of the WUS.

[0325] S806, the first communication device sends SIB1 to the terminal in response to the WUS. Correspondingly, the terminal receives the SIB1.

[0326] Optionally, in some embodiments, the method can not include S805 and S806.

[0327] Optionally, in some embodiments, S802 to S804 can be executed synchronously. Optionally, at least two of the short message, the third information and the configuration information of the WUS can be sent in the same signaling.

[0328] Optionally, in some embodiments, the execution order of S802 to S804 can not be limited. For example, S804 can be located before S802, or can be located before S803. For another example, S803 can be located before S802.

[0329] In the method, in a case where a state of the first communication device broadcasting the SIB1 changes, the first communication device can send configuration information of the WUS to the terminal. In this way, the problem that the terminal cannot receive the configuration information of the WUS and cannot receive the SIB1 can be avoided when the state of the first communication device broadcasting the SIB1 changes.

[0330] It can be understood that the embodiment shown in FIG. 8 is described by taking a single carrier scenario as an example. In a multi-carrier scenario, the first communication device can send the configuration information of the WUS to the terminal through another communication device. The other communication device can be a coordinated cell of the first communication device.

[0331] For example, the first communication device can send the configuration information of the WUS to the other communication device first. After the other communication device receives the configuration information of the WUS, the other communication device can send the configuration information of the WUS to the terminal.

[0332] In this example, the first communication device can send indication information to the terminal, and the indication information is used to indicate information of the other communication device.

[0333] Optionally, the indication information can include identification information and frequency point information of the other communication device. For example, the identification information of the other communication device can be a physical cell identity (PCI) or a cell global identifier (CGI). In this way, the terminal can search for the other communication device based on the identification information and the frequency point information of the other communication device, and receive the configuration information of the WUS sent by the other communication device.

[0334] In the multi-carrier scenario, the first communication device can also send the SIB1 to the terminal through the other communication device.

[0335] For example, the first communication device can send the SIB1 of the first communication device to the other communication device first. In a case where the terminal needs to request the SIB1, the terminal can send a WUS to the other communication device. After the other communication device receives the WUS, the other communication device can send the SIB1 of the first communication device to the terminal.

[0336] In this example, the first communication device can also send indication information to the terminal, and the indication information is used to indicate information of the other communication device.

[0337] Optionally, the indication information may include the identification information and frequency information of the other communication device. For example, the identification information of the other communication device may be PCI or CGI. Thus, the terminal can send a WUS to the other communication device based on its identification information and frequency information to request SIB1 from the first communication device.

[0338] In this example, the terminal can send WUS to the other communication device based on the WUS configuration information. Optionally, the WUS configuration information can be configured by the other communication device to the terminal.

[0339] In the technical solution of this application, for a connected terminal, the connected terminal can also request SIB1 from a communication device in an energy-saving state to satisfy the connected terminal's need to obtain SIB1.

[0340] Figure 9 is a schematic flowchart of a method for a terminal in a connected state to request SIB1 according to an embodiment of this application.

[0341] S901, the first communication device sends fourth information to the terminal, the fourth information indicating the configuration information of WUS. Accordingly, the terminal can receive the configuration information of WUS.

[0342] In this method, the first communication device is the communication device to which the terminal is connected.

[0343] Optionally, in some embodiments, the fourth information may be SIB1, which may carry WUS configuration information.

[0344] In one scenario, where the cell where the terminal is camped is always in an energy-saving state, the SIB1 can be the SIB1 broadcast by the first communication device when the non-connected terminal requests SIB1 through WUS.

[0345] In another scenario, when the cell where the terminal is camped changes from periodically broadcasting SIB1 to on-demand broadcasting SIB1, the SIB1 can be the SIB1 broadcast by the first communication device during periodic broadcasting.

[0346] Optionally, in other embodiments, the fourth information may be an RRC message, which may carry WUS configuration information.
