[0040] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0041] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0042] 1) Communication system scenario

[0043] Communication system scenarios can include terrestrial networks (TN) and non-terrestrial networks (NTN). NTN typically uses satellite communication to provide services to terrestrial users. Current NTN systems include New Radio (NR)-NTN and Internet of Things (IoT)-NTN systems, and other NTN systems may be included in the future.

[0044] For example, Figure 1A is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. As shown in Figure 1A, the communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal device, terminal device). The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminal devices located within that coverage area.

[0045] Figure 1A exemplarily illustrates a network device and two terminal devices. In some embodiments of this application, the communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area. This application does not limit this aspect.

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

[0047] For example, Figure 1C is a schematic diagram of another communication system architecture provided in an embodiment of this application. Referring to Figure 1C, it includes a terminal device 120, a satellite 130, and a base station 140. Wireless communication is possible between the terminal device 120 and the satellite 130, and communication is possible between the satellite 130 and the base station 140. The network formed between the terminal device 120, the satellite 130, and the base station 140 can also be called an NTN. In the communication system architecture shown in Figure 1C, the satellite 130 may not have the function of a base station, and communication between the terminal device 120 and the base station 140 requires relaying through the satellite 130. In this system architecture, the base station 140 can be referred to as a network device. In some embodiments of this application, the communication system may include multiple network devices, and the coverage area of ​​each network device may include other numbers of terminal devices; this application does not limit this.

[0048] In future communication systems such as Beyond Fifth Generation (B5G) and 6th Generation (6G), there may also be Distributed Multiple-In Multiple-Out (DMIMO, also known as distributed antenna systems) and / or Massive Multiple-In Multiple-Out (MMIMO, also known as massive antenna matrix systems) scenarios. In some cases, Distributed MIMO and / or Massive MIMO may also support cell-free or UE-centric network deployment scenarios. It should be understood that the above scenarios also apply to TN and / or NTN.

[0049] It is understandable that with the development of communication technology, due to the scarcity of spectrum resources, whether it is a TN network or an NTN network, or whether it is a network deployment scenario centered on base stations or a network deployment scenario centered on terminals, there may be situations where 5G networks and 6G networks need to share spectrum.

[0050] 2) Network energy saving background

[0051] Network energy saving (NES) is of great significance for environmental sustainability, reducing environmental impact (reducing greenhouse gas emissions), and saving operating costs. Energy consumption has become a key part of operators' operating expenses (OPEX). Energy costs for mobile networks account for approximately 23% of total operating costs. Most energy consumption comes from the radio access network, more specifically from the active antenna unit (AAU), with data centers and fiber optic transmission accounting for a smaller share. The power consumption of a single radio access can be divided into two parts: the dynamic part includes only the power consumption when data is being transmitted or received; the static part includes the power consumption at all times necessary for the operation of the radio access equipment, including power consumption when no data is being transmitted or received.

[0052] With the increasing prevalence of 5G in various industrial and geographical regions, there is a need to support very high data transmission rates to handle more advanced services and applications (such as XR). Network deployments are becoming denser, using more antennas, larger bandwidths, and more frequency bands. Considering the environmental impact of 5G, it is necessary to develop controlled, new solutions to enhance network energy efficiency. Therefore, based on the above objectives, network energy consumption models and evaluation methods on the network device side have been researched and developed in 5G networks to identify and study network energy-saving technologies in target deployment scenarios. The already defined power consumption model on the terminal device side is used as a reference. This research should focus on how to achieve more efficient dynamic and / or semi-static operation, and consider one or more network energy-saving technologies applied to the time, frequency, spatial, and power domains, combined with potential terminal device feedback support, potential terminal device auxiliary information, and information exchange or coordination technologies between network interfaces, to achieve more granular adaptive data transmission and / or reception.

[0053] It is worth noting that this study not only assesses potential network energy-saving gains, but also needs to evaluate and balance the impact on network and user performance by observing KPIs such as spectral efficiency, capacity, User Perceived Throughput (UPT), latency, UE power consumption, complexity, handover performance, call drop rate, initial access performance, and SLA security-related KPIs. This study should avoid having a significant impact on the aforementioned KPIs.

[0054] With the development of communication technology, research on 6G communication technology has begun. Considering the importance of network energy saving, possible network energy saving solutions need to be considered from the initial design stage of 6G communication technology.

[0055] 3) Initial Access in 5G NR Systems

[0056] In New Radio (NR) systems, the initial access process for terminal devices can be completed by detecting the Synchronization Signal / PBCH Block (SSB or SS / PBCH block) on the Sync Raster. The SSB is transmitted through a Discovery Burst Transmission Window or an SSB transmission opportunity window. These windows occur periodically, and the period can be configured by the network device using higher-layer parameters. During the initial access process, the terminal device attempts to search for SSBs based on their predefined possible time-frequency locations, and obtains time and frequency synchronization, radio frame timing, and cell ID from the detected SSBs.

[0057] One primary function of the SSB index is to allow the UE to obtain system timing information. Besides this, the SSB index also serves another function: indicating the quasi-co-location (QCL) relationship between SSBs, or in other words, indicating beam direction. QCL refers to the fact that the large-scale parameters of the channel experienced by a symbol on one antenna port can be inferred from the channel experienced by a symbol on another antenna port. These large-scale parameters can include delay spread, average delay, Doppler spread, Doppler shift, and spatial reception parameters. Specifically, in a 5G NR system, SSBs carried by different beams constitute an SSB burst set. Different SSB indices correspond to the time-domain location information of different SSBs within the burst set, and also to the specific SSB transmission beam information. SSBs with the same SSB index can be considered to have a QCL relationship; or, in other words, SSBs with the same SSB index experience the same or similar large-scale parameters of the channel. The UE can assume that the network device uses the same beam to transmit these SSBs; there is no QCL relationship between SSBs corresponding to different SSB indices, because they may come from different transmission beams of the network device and have experienced different channel transmission characteristics.

[0058] Upon detecting an SSB, the terminal device can determine the configuration of the Common Search Space (CSS) set for the Type 0 Physical Downlink Control Channel (Type 0-PDCCH) through the Master Information Block (MIB) message in the SSB. The terminal device can receive network device scheduling of System Information Block (SIB) 1 messages by listening to the Type 0-PDCCH CSS set. Both the MIB and SIB1 messages include system configuration information for the serving cell. Furthermore, the terminal device can receive network device scheduling of other system messages besides SIB1 messages by listening to the Type 0A-PDCCH CSS set, receive network device scheduling of paging messages by listening to the Type 2-PDCCH CSS set, and receive Paging Early Indication (PEI) information for paging messages sent by the network device by listening to the Type 2A-PDCCH CSS set.

[0059] The terminal device can also obtain the resource configuration of the Physical Random Access Channel (PRACH) Occasion (RO) during the random access process based on the received cell system message SIB1. RO is the time-frequency resource carrying the random access preamble. If two-step RACH transmission is supported, the resource configuration during the random access process also includes the Physical Uplink Shared Channel (PUSCH) resource configuration, also known as the PUSCH Occasion (PO). In the two-step RACH, message A (MsgA) includes the MsgA Preamble and the MsgA PUSCH; RO is the time-frequency resource used to carry the MsgA Preamble, and PO is the time-frequency resource used to carry the MsgA PUSCH.

[0060] A key feature of NR systems is their support for downlink multi-beaming. Before communication between network devices and terminal devices, the network devices need to know the beam the terminal device is on in order to set the appropriate beam direction during subsequent data transmission. Because of the mapping relationship between SSBs and ROs, the terminal device can select the RO associated with the downlink receive beam to send PRACH or Msg A during the random access procedure. After detecting PRACH or Msg A, the network device can determine the appropriate downlink receive beam direction for the terminal device.

[0061] Understandably, given the scarcity of spectrum resources, in certain scenarios—such as when 5G and 6G network equipment belong to the same operator, equipment vendor, or are located at the same site, or even are the same network equipment; or when spectrum is scarce; or when there is a load imbalance in the network (e.g., fewer users on the 5G network and more on the 6G network; or vice versa)—it may be necessary for 5G and 6G networks to share spectrum resources for communication transmission. In scenarios involving shared spectrum resources, reducing the power consumption of network equipment and avoiding or mitigating interference in communication signal transmission between the two networks sharing spectrum resources to improve the effectiveness and reliability of information transmission are problems that need to be addressed.

[0062] Please refer to Figure 2, which shows a flowchart of a wireless communication method provided in an embodiment of this application. This method can be interactively executed by a terminal device and a first network device. The terminal device can be terminal device 120 in the aforementioned network architecture, or a terminal device in other network architectures. The first network device can be network device 110, satellite 130, or base station 140 in the aforementioned network architecture, or a network device in other network architectures; this application is not limited in this regard. The method may include at least some of the following steps:

[0063] Step 210: The first network device in the first network transmits a first downlink channel or signal on the first downlink time domain resource; the terminal device receives the first downlink channel or signal transmitted by the first network device in the first network on the first downlink time domain resource.

[0064] In this embodiment of the application, the first downlink channel or signal may be a channel or signal periodically transmitted by the first network.

[0065] For example, the first downlink channel or signal may be a broadcast signal, synchronization signal, or synchronization signal block of the first network, etc. Alternatively, the first downlink channel or signal may also be a new channel or signal.

[0066] In this embodiment of the application, the terminal device may attempt to receive the first downlink channel or signal on the first downlink time domain resource by means of blind detection.

[0067] Step 220: The terminal device sends a first uplink channel or signal through the first uplink time domain resource. The first uplink channel or signal carries request information, which is used to request system configuration information of the second network.

[0068] The system configuration information can be used for terminal devices to access the second network and communicate with the second network devices in the second network.

[0069] The first downlink channel or signal can be used to instruct the terminal device to request system configuration information of the second network; that is, when the terminal device receives the first downlink channel or signal in the first network, it can send a request to obtain system configuration information of the second network.

[0070] In this embodiment, the terminal device does not directly detect or search for wireless signals carrying system configuration information of the second network. Instead, when it needs to access the second network, it actively requests the system configuration information of the second network upon receiving the first downlink channel or signal of the first network. Accordingly, the network devices in the second network do not need to periodically broadcast the system configuration information of the second network. Instead, they only need to send the system configuration information of the second network when the terminal device initiates a request. This can significantly reduce the power consumption required for transmitting the system configuration information of the second network and improve the energy-saving effect of the network devices.

[0071] In summary, the solution shown in the embodiments of this application allows the terminal device to send a request message to request system configuration information of the second network when it receives the first downlink channel or signal in the first network, provided that the terminal device supports two wireless networks simultaneously. This solution eliminates the need for the network device of the second network to continuously or periodically send system configuration information, thereby significantly reducing the power consumption of the network device of the second network.

[0072] Based on the scheme shown in Figure 2, please refer to Figure 3, which illustrates a flowchart of a wireless communication method provided in an embodiment of this application. This method can be interactively executed by a terminal device, a first network device, and a second network device. The terminal device can be terminal device 120 in the aforementioned network architecture, or a terminal device in other network architectures. The first and second network devices can be network device 110, satellite 130, or base station 140 in the aforementioned network architecture, or network devices in other network architectures; this application does not limit this. The method may include at least some of the following steps:

[0073] Step 310: The first network device in the first network transmits a first downlink channel or signal on the first downlink time domain resource; the terminal device receives the first downlink channel or signal transmitted by the first network device in the first network on the first downlink time domain resource.

[0074] Step 320: The terminal device sends a first uplink channel or signal through the first uplink time domain resource. The first uplink channel or signal carries request information, which is used to request system configuration information of the second network.

[0075] Step 330: The second network device in the second network obtains the request information.

[0076] In this embodiment, when the second network device receives a request from the terminal device, if it determines that it will send system configuration information to the terminal device, it can send the system configuration information of the second network to the terminal device. Alternatively, when the second network device receives a request from the terminal device, it can send a response to the terminal device, which indicates whether the second network device should send the system configuration information of the second network to the terminal device. If it determines that it will send system configuration information to the terminal device, it can then send the system configuration information of the second network to the terminal device.

[0077] Accordingly, after sending the request information, the terminal device can perform a receiving operation on the resource where the second network device may send system configuration information. If the second network device sends system configuration information, the terminal device can receive the system configuration information. Alternatively, after sending the request information, the terminal device can listen for the response information sent by the second network device. If, based on the received response information, it is determined that the second network device will send system configuration information for the second network, the terminal device can receive the system configuration information on the resource where the second network device may send system configuration information.

[0078] In summary, the solution shown in the embodiments of this application allows the terminal device to send a request message to request system configuration information of the second network when it receives the first downlink channel or signal in the first network, provided that the terminal device supports two wireless networks simultaneously. This solution eliminates the need for the network device of the second network to continuously or periodically send system configuration information, thereby significantly reducing the power consumption of the network device of the second network.

[0079] Based on the scheme shown in Figure 3, please refer to Figure 4, which shows a framework diagram of a network access process provided in an embodiment of this application; as shown in Figure 4, the first network device 41 corresponds to the first network, and the second network device 42 corresponds to the second network; wherein, the first network and the second network are two different networks; the terminal device 43 supports both the first network and the second network.

[0080] S1, in the network architecture shown in Figure 4, the first network device 41 periodically transmits the first downlink channel or signal (e.g., periodically transmits the SSB of the first network); while the second network device 42 does not periodically transmit the system configuration information of the second network.

[0081] S2, when the terminal device needs to access the second network, it detects the first downlink channel or signal on resources where the first downlink channel or signal may exist.

[0082] S3, upon receiving the first downlink channel or signal, the terminal device sends a first uplink channel or signal carrying request information.

[0083] S4. After obtaining the request information, the second network device 42 sends system configuration information to the terminal device.

[0084] S5. After receiving the system configuration information, the terminal device accesses the second network according to the system configuration information.

[0085] Based on the scheme shown in Figure 2 or Figure 3 above, please refer to Figure 5, which shows a flowchart of a wireless communication method provided in an embodiment of this application. This method can be interactively executed by a terminal device, a first network device, and a second network device. The terminal device can be terminal device 120 in the aforementioned network architecture, or a terminal device in other network architectures. The first and second network devices can be network device 110, satellite 130, or base station 140 in the aforementioned network architecture, or network devices in other network architectures; this application does not limit this. The method may include at least some of the following steps:

[0086] Step 510: The first network device in the first network transmits a first downlink channel or signal on the first downlink time domain resource; the terminal device receives the first downlink channel or signal transmitted by the first network device in the first network on the first downlink time domain resource.

[0087] In some embodiments, the first downlink channel or signal includes at least one of the following: a synchronization signal, an SSB, a physical downlink control channel (PDCCH) of a scheduling system message block (SIB), and a physical downlink shared channel (PDSCH) carrying the SIB.

[0088] In this embodiment, the synchronization signal, SSB, physical downlink control channel PDCCH of scheduling system message block SIB, physical downlink shared channel PDSCH carrying SIB, etc. in the first network can be used to instruct the terminal device to obtain time-domain synchronization, frequency-domain synchronization, or system configuration information of the second network. This eliminates the need for the first network to instruct the terminal device to obtain the system configuration information of the second network through dedicated channels or signals, thereby saving the resources of the first network device.

[0089] Optionally, the first downlink channel or signal may also be a new downlink channel or signal other than a synchronization signal, SSB, physical downlink control channel PDCCH of scheduling system message block SIB, or physical downlink shared channel PDSCH carrying SIB.

[0090] Step 520: The terminal device sends a first uplink channel or signal through the first uplink time domain resource. The first uplink channel or signal carries request information, which is used to request system configuration information of the second network.

[0091] In some embodiments, the first uplink time domain resource is the uplink time domain resource in the first network, and sending the first uplink channel or signal through the first uplink time domain resource includes: sending the first uplink channel or signal to the first network device through the first uplink time domain resource; that is, the first uplink channel or signal is a channel or signal sent by the terminal device to the first network device through the first uplink time domain resource; in this embodiment, the terminal device can send the first uplink channel or signal carrying request information to the first network device through the uplink time domain resource in the first network, and this process does not need to be performed through the second network, thereby saving the resources of the network devices in the second network.

[0092] Alternatively, the first uplink time domain resource is the uplink time domain resource in the second network, and sending the first uplink channel or signal through the first uplink time domain resource includes: sending the first uplink channel or signal to the second network device through the first uplink time domain resource; that is, the first uplink channel or signal is the channel or signal sent by the terminal device to the second network device through the first uplink time domain resource; wherein, the second network device is a network device in the second network; in this embodiment of the application, the terminal device can send the first uplink channel or signal carrying request information to the second network device through the uplink time domain resource in the second network, and this process does not need to be performed through the first network, thereby saving the resources of the network devices in the first network.

[0093] or,

[0094] The first uplink time domain resource is the uplink time domain resource in the first network. Sending the first uplink channel or signal through the first uplink time domain resource includes: sending the first uplink channel or signal to the second network device through the first uplink time domain resource; that is, the first uplink channel or signal is a channel or signal sent by the terminal device to the second network device through the first uplink time domain resource. In this embodiment, the terminal device can send a first uplink channel or signal carrying request information to the second network device through the uplink time domain resource in the first network. This process can reuse resources in the first network to communicate with network devices in the second network, thereby improving the flexibility of uplink time domain resources between the two networks. Optionally, in this case, the first network device and the second network device are the same network device, or the first network device and the second network device are network devices from the same equipment vendor, or the first network device and the second network device are co-located network devices.

[0095] Alternatively, the first uplink time domain resource is the uplink time domain resource in the second network, and sending the first uplink channel or signal through the first uplink time domain resource includes: sending the first uplink channel or signal to the first network device through the first uplink time domain resource; that is, the first uplink channel or signal is a channel or signal sent by the terminal device to the first network device through the first uplink time domain resource. In this embodiment, the terminal device can send a first uplink channel or signal carrying request information to the first network device through the uplink time domain resource in the second network. This process can reuse resources in the second network to communicate with network devices in the first network, thereby improving the flexibility of uplink time domain resources between the two networks. Optionally, in this case, the first network device and the second network device are the same network device, or the first network device and the second network device are network devices from the same equipment vendor, or the first network device and the second network device are co-located network devices.

[0096] In some embodiments, the first downlink time-domain resource and the first uplink time-domain resource are associated; and / or,

[0097] The first downlink channel or signal and the first uplink channel or signal have a quasi-co-address (QCL) relationship.

[0098] The first downlink time domain resource and the first uplink time domain resource are related, which may include the following situations:

[0099] There is a correlation between the time domain position of the first downlink time domain resource and the time domain position of the first uplink time domain resource; and / or, there is a correlation between the frequency domain position of the first downlink time domain resource (e.g., the frequency domain position occupied by the first downlink channel or signal transmitted on the first downlink time domain resource) and the frequency domain position of the first uplink time domain resource (e.g., the frequency domain position occupied by the first uplink channel or signal transmitted on the first uplink time domain resource).

[0100] For example, the time domain position of the first downlink time domain resource has a first offset value with the time domain position of the first uplink time domain resource; and / or, the frequency domain position of the first downlink time domain resource has a second offset value with the frequency domain position of the first uplink time domain resource.

[0101] In this embodiment of the application, when there is a preset association between the first downlink time domain resource and the first uplink time domain resource, the terminal device can determine the first uplink time domain resource based on the first downlink time domain resource through the association, thereby simplifying resource scheduling and improving communication efficiency.

[0102] Furthermore, in this embodiment of the application, when there is a quasi-co-located (QCL) relationship between the first downlink channel or signal and the first uplink channel or signal, the terminal device can determine the beam corresponding to the first uplink channel or signal based on the beam corresponding to the first downlink channel or signal through the association relationship and the beam correspondence between the downlink and uplink transmissions, thereby simplifying the execution logic of beam control and improving communication efficiency.

[0103] In some embodiments, the method further includes:

[0104] The first network device sends a first indication message, and correspondingly, the terminal device receives the first indication message sent by the first network device; the first indication message is used to indicate one or more of the following information:

[0105] Whether the first network and the second network share downlink spectrum resources;

[0106] Whether the first downlink channel or signal is used to assist the terminal device in accessing the second network;

[0107] Whether to allow terminal devices to access the second network through the first network;

[0108] The cell identifier of the second network;

[0109] The offset value between the time unit of the first network and the time unit of the second network; optionally, the time unit here may include a downlink time unit and / or an uplink time unit;

[0110] The relationship between the first downlink time domain resource and the first uplink time domain resource.

[0111] For example, the first indication information may carry an explicit identifier, which may be used to indicate whether the first network and the second network share downlink spectrum resources, and / or, the identifier may be used to indicate whether the first downlink channel or signal is used to assist the terminal device in accessing the second network, and / or, the identifier may be used to indicate whether the terminal device is allowed to access the second network through the first network.

[0112] Alternatively, the first indication information may also implicitly indicate whether the first network and the second network share downlink spectrum resources, whether the first downlink channel or signal is used to assist the terminal device in accessing the second network, and / or whether the terminal device is allowed to access the second network through the first network. For example, when the first indication information carries the cell identifier of the second network, the offset value between the time units of the first network and the second network, and / or the association between the first downlink time domain resources and the first uplink time domain resources, it can indicate that the first network and the second network share downlink spectrum resources, the first downlink channel or signal is used to assist the terminal device in accessing the second network, and / or that the terminal device is allowed to access the second network through the first network. Conversely, when the first indication information does not carry the cell identifier of the second network, the offset value between the time units of the first network and the second network, and / or the association between the first downlink time domain resources and the first uplink time domain resources, it can indicate that the first network and the second network do not share downlink spectrum resources, the first downlink channel or signal is not used to assist the terminal device in accessing the second network, and / or that the terminal device is not allowed to access the second network through the first network.

[0113] In the scheme shown in the embodiments of this application, the first network device can send first indication information to the terminal device to assist the terminal device in determining whether to obtain the system configuration information of the second network through the first network, and how to obtain the system configuration information of the second network through the first network, thereby ensuring the accuracy and success rate of the terminal device obtaining the system configuration information of the second network through the first network, thereby improving communication efficiency.

[0114] In some embodiments, the first indication information is carried in one or more of the following messages: SSB, MIB, Physical Broadcast Channel (PBCH), system message, and Radio Resource Control (RRC) message.

[0115] In some embodiments, the terminal device transmits a first uplink channel or signal through a first uplink time domain resource, including: transmitting the first uplink channel or signal through the first uplink time domain resource based on the first downlink channel or signal.

[0116] For example, the terminal device may determine downlink synchronization and / or uplink synchronization based on a first downlink channel or signal, and transmit the first uplink channel or signal based on the downlink synchronization and / or uplink synchronization. The downlink synchronization and / or uplink synchronization may be uplink synchronization and / or uplink synchronization between the terminal device and a first network, or it may be uplink synchronization and / or uplink synchronization between the terminal device and a second network.

[0117] For example, the terminal device can determine the time-domain position and / or frequency-domain position of the first uplink channel or signal based on the time-domain position and / or frequency-domain position of the first downlink channel or signal, and then transmit the first uplink channel or signal at the determined time-domain position and / or frequency-domain position.

[0118] In the solution shown in the embodiments of this application, the terminal device can perform the subsequent steps of sending the first uplink channel or signal through the first downlink channel or signal, which simplifies the control logic for sending the first uplink channel or signal and improves communication efficiency.

[0119] In some embodiments, the first uplink channel or signal includes at least one of the following: Uplink-Wake Up Signal (UL-WUS), Physical Random Access Channel (PRACH), Physical Uplink Control Channel (PUCCH), and Sounding Reference Signal (SRS).

[0120] In this embodiment, the terminal device can request system configuration information of the second network by reusing signals such as PRACH, PUCCH, and SRS, which can simplify the system design. Alternatively, a new signal, such as UL-WUS, can be introduced to request system configuration information of the second network, thereby improving the utilization rate of signaling resources in the communication system.

[0121] In some embodiments, the first uplink time domain resource is configured by the first network device. In this case, the resources for the terminal device to obtain the system configuration information of the second network can be configured by the first network device. On the one hand, this ensures the flexibility of resource configuration when the terminal device obtains the system configuration information of the second network and reduces the transmission interference caused by the first uplink signal or channel sent by the terminal device. On the other hand, it can simplify the configuration operation of the network devices in the second network and improve the energy-saving effect of the network devices in the second network.

[0122] Alternatively, the first uplink time domain resource is configured by the second network device. In this case, the resources for the terminal device to obtain the system configuration information of the second network can be configured by the second network device. On the one hand, this ensures the flexibility of resource configuration when the terminal device obtains the system configuration information of the second network and reduces the transmission interference caused by the first uplink signal or channel sent by the terminal device. On the other hand, it simplifies the configuration operation of the network devices in the first network and improves the energy-saving effect of the network devices in the first network.

[0123] Alternatively, the first uplink time domain resource is a predefined resource; in this case, the resources for the terminal device to obtain the system configuration information of the second network do not need to be configured by the network device, which can simplify the configuration operation of the network devices in the first network and the second network and improve the energy-saving effect of the network devices in the first network and the second network.

[0124] Step 530: The first network device or the second network device obtains the request information.

[0125] Specifically, when the terminal device sends the first uplink channel or signal to the first network device through the first uplink time domain resource, the first network device can obtain the request information from the first uplink channel or signal.

[0126] Alternatively, when the terminal device sends the first uplink channel or signal to the first network device through the first uplink time domain resource, the first network device can obtain request information from the first uplink channel or signal and send the request information to the second network device.

[0127] Alternatively, when the terminal device sends the first uplink channel or signal to the second network device through the first uplink time domain resource, the second network device can obtain the request information from the first uplink channel or signal.

[0128] Alternatively, when the terminal device sends the first uplink channel or signal to the second network device through the first uplink time domain resource, the second network device can obtain the request information from the first uplink channel or signal and send the request information to the first network device.

[0129] Step 540: The first network device or the second network device transmits a second downlink channel or signal on the second downlink time domain resources; the terminal device receives the second downlink channel or signal on the second downlink time domain resources.

[0130] The second downlink channel or signal is used to obtain system configuration information of the second network.

[0131] In this embodiment of the application, after the first network device or the second network device obtains the request information, if it determines to send the system configuration information of the second network to the terminal device, it can send the second downlink channel or signal on the second downlink time domain resources. Correspondingly, the terminal device can attempt to receive (e.g., blindly detect) the second downlink channel or signal on the second downlink time domain resources.

[0132] In some embodiments, after receiving the request information, the first network device or the second network device may send response information to the terminal device. This response information indicates whether to send system configuration information of the second network. Optionally, if the response information indicates that the system configuration information of the second network should be sent, the first network device or the second network device will send the system configuration information of the second network. Optionally, if the response information indicates that the system configuration information of the second network should not be sent, the first network device or the second network device will not send the system configuration information of the second network.

[0133] In some embodiments, the system configuration information of the second network includes one or more of the following:

[0134] The second network includes synchronization signals or synchronization signal blocks, mobility management-related configuration information, paging configuration information of cells in the second network, and uplink access configuration information of cells in the second network.

[0135] In some embodiments, the request information is used to request one or more of the following:

[0136] The second network includes synchronization signals or synchronization signal blocks, mobility management-related configuration information, paging configuration information of cells in the second network, and uplink access configuration information of cells in the second network.

[0137] In some embodiments, when the request information is used to request a synchronization signal or synchronization signal block in the second network, the second network device sends the synchronization signal or synchronization signal block in the second network; that is, the system configuration information of the second network includes at least the synchronization signal or synchronization signal block of the cell in the second network. Alternatively, when the request information is used to request a synchronization signal or synchronization signal block in the second network, the second network device may send response information to the terminal device, the response information indicating whether to send the synchronization signal or synchronization signal block in the second network. Optionally, if the response information indicates that the synchronization signal or synchronization signal block in the second network should be sent, the second network device sends the synchronization signal or synchronization signal block in the second network. Optionally, if the response information indicates that the synchronization signal or synchronization signal block in the second network should not be sent, the second network device does not send the synchronization signal or synchronization signal block in the second network.

[0138] In some embodiments, when the request information is used to request the mobility management-related configuration information, the system configuration information of the second network includes at least the mobility management-related configuration information. Optionally, the system configuration information of the second network may also include paging configuration information of cells in the second network and / or uplink access configuration information of cells in the second network.

[0139] When the request information is used to request paging configuration information of a cell in the second network, the system configuration information of the second network includes at least the paging configuration information of the cell in the second network. Optionally, the system configuration information of the second network may also include mobility management-related configuration information and / or uplink access configuration information of the cell in the second network.

[0140] When the request information is used to request uplink access configuration information of a cell in the second network, the system configuration information of the second network includes at least the uplink access configuration information of the cell in the second network. Optionally, the system configuration information of the second network may also include mobility management-related configuration information and / or mobility management-related configuration information.

[0141] In some embodiments, when the request information is used to request a synchronization signal or synchronization signal block of a cell in the second network, the system configuration information of the second network includes the synchronization signal or synchronization signal block of the cell in the second network, the mobility management-related configuration information, the paging configuration information of the cell in the second network, and the uplink access configuration information of the cell in the second network; or,

[0142] When the request information is used to request mobility management-related configuration information, the system configuration information of the second network includes the mobility management-related configuration information, the paging configuration information of the cells in the second network, and the uplink access configuration information of the cells in the second network; or,

[0143] When the request information is used to request paging configuration information of a cell in the second network, the system configuration information of the second network includes the paging configuration information and the uplink access configuration information of the cell in the second network; or,

[0144] When the request information is used to request paging configuration information of a cell in the second network, the system configuration information of the second network includes the mobility management-related configuration information and the paging configuration information of the cell in the second network.

[0145] The solution described in the embodiments of this application allows the first network device or the second network device to determine which system configuration information of the second network to send to the terminal device based on the configuration information requested by the terminal device, thereby improving the flexibility of system configuration information transmission.

[0146] In some embodiments, the second downlink time domain resource is a downlink time domain resource in the first network, and the first network device transmits a second downlink channel or signal on the second downlink time domain resource; correspondingly, the terminal device receives the second downlink channel or signal on the second downlink time domain resource, including: the terminal device receives the second downlink channel or signal transmitted by the first network device on the second downlink time domain resource.

[0147] Alternatively, the second downlink time domain resource is a downlink time domain resource in the second network, and the second network device transmits a second downlink channel or signal on the second downlink time domain resource; correspondingly, the terminal device receives the second downlink channel or signal on the second downlink time domain resource, including: the terminal device receives the second downlink channel or signal transmitted by the second network device on the second downlink time domain resource;

[0148] Alternatively, the second downlink time domain resource is the downlink time domain resource in the first network, and the second network device transmits a second downlink channel or signal on the second downlink time domain resource; correspondingly, the terminal device receives the second downlink channel or signal on the second downlink time domain resource, including: the terminal device receives the second downlink channel or signal transmitted by the second network device on the second downlink time domain resource;

[0149] Alternatively, the second downlink time domain resource is a downlink time domain resource in the second network, and the first network device transmits a second downlink channel or signal on the second downlink time domain resource; correspondingly, the terminal device receives the second downlink channel or signal on the second downlink time domain resource, including: the terminal device receives the second downlink channel or signal transmitted by the first network device on the second downlink time domain resource.

[0150] In some embodiments, the first downlink time-domain resource and the second downlink time-domain resource are associated; and / or,

[0151] There is a QCL relationship between the first downlink channel or signal and the second downlink channel or signal.

[0152] The first downlink time-domain resource and the second downlink time-domain resource are associated, which may include the following situations:

[0153] There is a correlation between the time domain position of the first downlink time domain resource and the time domain position of the second downlink time domain resource; and / or, there is a correlation between the frequency domain position of the first downlink time domain resource (e.g., the frequency domain position occupied by the first downlink channel or signal transmitted on the first downlink time domain resource) and the frequency domain position of the second downlink time domain resource (e.g., the frequency domain position occupied by the second downlink channel or signal transmitted on the second downlink time domain resource).

[0154] For example, there is a third offset value between the time domain position of the first downlink time domain resource and the time domain position of the second downlink time domain resource; and / or, there is a fourth offset value between the frequency domain position of the first downlink time domain resource and the frequency domain position of the second downlink time domain resource.

[0155] In this embodiment of the application, when there is a preset association relationship between the first downlink time domain resource and the second downlink time domain resource, the terminal device can determine the second downlink time domain resource based on the first downlink time domain resource through the association relationship, thereby simplifying resource scheduling and improving communication efficiency.

[0156] Furthermore, in this embodiment of the application, when there is a quasi-co-located (QCL) relationship between the first downlink channel or signal and the second downlink channel or signal, the terminal device can determine the beam corresponding to the second downlink channel or signal based on the beam corresponding to the first downlink channel or signal through the association relationship, thereby simplifying the execution logic of beam control and improving communication efficiency.

[0157] In some embodiments, the first uplink time-domain resource and the second downlink time-domain resource are associated; and / or,

[0158] There is a QCL relationship between the first uplink channel or signal and the second downlink channel or signal.

[0159] The first uplink time domain resource and the second downlink time domain resource are related, which may include the following situations:

[0160] There is a correlation between the time domain position of the first uplink time domain resource and the time domain position of the second downlink time domain resource; and / or, there is a correlation between the frequency domain position of the first uplink time domain resource (e.g., the frequency domain position occupied by the first uplink channel or signal transmitted on the first uplink time domain resource) and the frequency domain position of the second downlink time domain resource (e.g., the frequency domain position occupied by the second downlink channel or signal transmitted on the second downlink time domain resource).

[0161] For example, there is a fifth offset value between the time domain position of the first uplink time domain resource and the time domain position of the second downlink time domain resource; and / or, there is a sixth offset value between the frequency domain position of the first uplink time domain resource and the frequency domain position of the second downlink time domain resource.

[0162] In this embodiment of the application, when there is a preset association between the first uplink time domain resource and the second downlink time domain resource, the terminal device can determine the second downlink time domain resource based on the first uplink time domain resource through the association, thereby simplifying resource scheduling and improving communication efficiency.

[0163] Furthermore, in this embodiment of the application, when there is a quasi-co-located (QCL) relationship between the first uplink channel or signal and the second downlink channel or signal, the terminal device can determine the beam corresponding to the second downlink channel or signal based on the beam corresponding to the first uplink channel or signal through the association relationship and the correspondence between the uplink and downlink transmission beams, thereby simplifying the execution logic of beam control and improving communication efficiency.

[0164] In some embodiments, the second downlink channel or signal includes at least one of the following: a PDCCH that schedules system configuration information of the second network, and a PDSCH that carries system configuration information of the second network.

[0165] For example, if the second downlink channel or signal contains a PDCCH that schedules the system configuration information of the second network, after receiving the second downlink channel or signal, the terminal device determines the downlink resource where the system configuration information of the second network is located according to the PDCCH, and receives the system configuration information of the second network on the corresponding downlink resource.

[0166] For example, if the second downlink channel or signal contains a PDSCH carrying system configuration information of the second network, the terminal device, after receiving the second downlink channel or signal, obtains the system configuration information of the second network from the PDSCH.

[0167] For example, if the second downlink channel or signal contains a PDCCH that schedules the system configuration information of the second network and a PDSCH that carries the system configuration information of the second network, after receiving the PDCCH, the terminal device determines the downlink resource where the PDSCH is located based on the PDCCH, receives the PDSCH on the corresponding downlink resource, and obtains the system configuration information of the second network from the PDSCH.

[0168] In some embodiments, the second downlink time domain resource is configured by the first network device. In this case, the resources for the terminal device to receive the system configuration information of the second network can be configured by the first network device. On the one hand, this ensures the flexibility of resource configuration when the terminal device obtains the system configuration information of the second network and reduces the transmission interference caused by sending the system configuration information of the second network to the terminal device. On the other hand, it can simplify the configuration operation of network devices in the second network and improve the energy-saving effect of network devices in the second network.

[0169] Alternatively, the second downlink time domain resource is configured by the second network device. In this case, the resources for the terminal device to receive the system configuration information of the second network can be configured by the second network device. On the one hand, this ensures the flexibility of resource configuration when the terminal device obtains the system configuration information of the second network and reduces the transmission interference caused by sending the system configuration information of the second network to the terminal device. On the other hand, it can simplify the configuration operation of the network devices in the first network and improve the energy-saving effect of the network devices in the first network.

[0170] Alternatively, the second downlink time domain resource is a predefined resource; in this case, the resources for the terminal device to obtain the system configuration information of the second network do not need to be configured by the network device, which can simplify the configuration operation of the network devices in the first network and the second network and improve the energy-saving effect of the network devices in the first network and the second network.

[0171] Step 550: The terminal device accesses the second network according to the system configuration information of the second network.

[0172] In some embodiments, the terminal device accesses the second network based on the system configuration information of the second network, including one or more of the following:

[0173] When the system configuration information of the second network includes mobility management-related configuration information, the terminal device performs mobility measurement on the cells of the second network according to the mobility management-related configuration information;

[0174] When the system configuration information of the second network includes the paging configuration information of the cells in the second network, the terminal device listens for paging messages in the second network according to the paging configuration information of the cells in the second network;

[0175] When the system configuration information of the second network includes at least the uplink access configuration information of the cells in the second network, the terminal device initiates uplink access to the cells in the second network according to the uplink access configuration information of the cells in the second network.

[0176] In this embodiment, the terminal device can obtain the configuration information required for mobility measurement, paging monitoring and / or uplink access to the second network through the first network, without the network devices in the second network needing to continuously send the configuration related to mobility measurement, paging monitoring and / or uplink access, thereby reducing the power consumption of the network devices in the second network.

[0177] In some embodiments, the method further includes:

[0178] A first network device schedules the terminal device to perform a first uplink transmission and / or a first downlink transmission using resources in the first network; correspondingly, the terminal device performs a first uplink transmission and / or a first downlink transmission using resources in the first network according to the scheduling of the first network device; and / or,

[0179] The second network device schedules the terminal device to perform a second uplink transmission and / or a second downlink transmission through resources in the second network; correspondingly, according to the scheduling of the second network device, the terminal device performs a second uplink transmission and / or a second downlink transmission through resources in the second network.

[0180] In this embodiment, the terminal device can simultaneously support the first network and the second network, and can perform corresponding uplink and / or downlink transmissions on the resources of the two networks respectively according to the scheduling of the first network device and the second network device, thereby ensuring the flexibility of the terminal device in performing transmissions in different networks, reducing transmission interference between different networks, and improving the transmission efficiency of the entire system.

[0181] In some embodiments, when the first downlink transmission is performed and the first downlink transmission corresponds to a first Hybrid Automatic Repeat ReQuest-ACK (HARQ-ACK) message, the method further includes:

[0182] The first HARQ-ACK information is transmitted through resources in the first network; that is, the first HARQ-ACK information is transmitted through resources in the first network; and / or,

[0183] The first HARQ-ACK information is transmitted through resources in the second network; that is, the first HARQ-ACK information is transmitted through resources in the second network.

[0184] In this embodiment, the HARQ-ACK information corresponding to the first downlink transmission in the first network can be transmitted through resources in the first network and / or the second network, which can improve the effect of resource reuse between different networks.

[0185] In some embodiments, when the second downlink transmission is performed and the second downlink transmission corresponds to second HARQ-ACK information, the method further includes:

[0186] The second HARQ-ACK information is transmitted through resources in the first network; that is, the second HARQ-ACK information is transmitted through resources in the first network; and / or,

[0187] The second HARQ-ACK information is transmitted through resources in the second network; that is, the second HARQ-ACK information is transmitted through resources in the second network.

[0188] In this embodiment, the HARQ-ACK information corresponding to the second downlink transmission in the second network can be transmitted through resources in the first network and / or the second network, which can improve the effect of resource reuse between different networks.

[0189] In some embodiments, when performing the first downlink transmission and the second downlink transmission, and the first downlink transmission corresponds to first HARQ-ACK information and the second downlink transmission corresponds to second HARQ-ACK information, the method further includes:

[0190] The first HARQ-ACK information and the second HARQ-ACK information are transmitted through different channels respectively; that is, the first HARQ-ACK information and the second HARQ-ACK information are transmitted through different channels respectively.

[0191] Alternatively, the first HARQ-ACK information and the second HARQ-ACK information can be transmitted through the same channel; that is, the first HARQ-ACK information and the second HARQ-ACK information can be transmitted through the same channel.

[0192] In this embodiment, the HARQ-ACK information corresponding to downlink transmissions in different networks can be transmitted through different channels, thereby ensuring the flexibility of HARQ-ACK information transmission across different networks. Alternatively, the HARQ-ACK information corresponding to downlink transmissions in different networks can also be transmitted through the same channel, thereby improving the channel multiplexing effect between different networks.

[0193] In some embodiments, when the first HARQ-ACK information and the second HARQ-ACK information are transmitted through the same channel, or in other words, when the first HARQ-ACK information and the second HARQ-ACK information are transmitted through the same channel, the first HARQ-ACK information and the second HARQ-ACK information are encoded independently; or, the first HARQ-ACK information and the second HARQ-ACK information are jointly encoded.

[0194] In the embodiments of this application, when the downlink transmissions in different networks correspond to HARQ-ACK information transmitted through the same channel, the HARQ-ACK information in different networks can be encoded independently, thereby ensuring the flexibility of HARQ-ACK information encoding in different networks; or, the HARQ-ACK information in different networks can also be jointly encoded, thereby simplifying the complexity of HARQ-ACK information encoding and decoding in different networks and improving the reception efficiency of HARQ-ACK information in different networks.

[0195] In some embodiments, the association between the first downlink time domain resource and the first uplink time domain resource, the association between the first downlink time domain resource and the second downlink time domain resource, and / or the association between the first uplink time domain resource and the second downlink time domain resource can be determined by the configuration information of the first network device; or...

[0196] The association between the first downlink time domain resource and the first uplink time domain resource, the association between the first downlink time domain resource and the second downlink time domain resource, and / or the association between the first uplink time domain resource and the second downlink time domain resource can be determined by the configuration information of the second network device; or...

[0197] The association between the first downlink time domain resource and the first uplink time domain resource, the association between the first downlink time domain resource and the second downlink time domain resource, and / or the association between the first uplink time domain resource and the second downlink time domain resource can be determined by predefined rules.

[0198] In some embodiments, the first network is a 5G network, and the second network is a 6G network; or...

[0199] The first network is a 6G network, and the second network is a 5G network; or,

[0200] The first network is a TN network, and the second network is an NTN network; or,

[0201] The first network is an NTN network, and the second network is a TN network.

[0202] In some embodiments, the first network device and the second network device are the same network device; or, the first network device and the second network device are different network devices.

[0203] In some embodiments, the first network device and the second network device are co-located network devices; or, the first network device and the second network device are non-co-located network devices.

[0204] In some embodiments, the first network device and the second network device are network devices of the same operator or the same equipment vendor; or, the first network device and the second network device are network devices of different operators or different equipment vendors.

[0205] In some embodiments, where the first network device and the second network device are the same network device, the first network device can provide services to both the first network and the second network. For example, in the case where 5G and 6G networks share spectrum resources, the first network device can provide services to both the 5G and 6G networks simultaneously.

[0206] In some embodiments, when the first network device and the second network device are the same network device, the latency of information interaction between the first network and the second network can be considered to be very small, for example, 0.

[0207] It is understandable that even when the first network and the second network share a site, the first network device and the second network device can be different network devices because different networks have different requirements for their corresponding network devices. In some embodiments, when the first network device and the second network device are different network devices, it can be assumed that the information interaction between the first network and the second network is carried out through the interface between the network devices.

[0208] In some embodiments, the first network and the second network share downlink spectrum resources; and / or, the first network and the second network share uplink spectrum resources.

[0209] In this embodiment of the application, when downlink spectrum resources and / or uplink spectrum resources are shared between the first network and the second network, the terminal device can request to obtain the system configuration information of the second network through the first downlink channel or signal sent by the network device in the first network. This can reduce the transmission interference caused by the access of the terminal device when the two networks share spectrum resources, and improve the communication efficiency of the system.

[0210] Based on the solutions shown in the above embodiments, the solution involved in this application can be considered when different networks share at least downlink spectrum resources. For example, when 5G networks and 6G networks share at least downlink spectrum resources, the common channel or signal (e.g., SSB) that is continuously transmitted in the 5G network can be used to assist the initial access of terminal devices in the 6G network. In the solution involved in this application, the 6G network is a network that supports network energy saving, and the configuration such as system messages in the network is not continuously transmitted. When a terminal device wants to access the 6G network, it needs to initiate a request to the network device through an uplink channel or signal (e.g., UL-WUS, uplink wake-up signal) to transmit a synchronization signal or synchronization signal block or system message configuration (e.g., on-demand SS / SSB / SI). After detecting the request signal of the terminal device, the network device sends the 6G network's synchronization signal or synchronization signal block or system message configuration to the terminal device based on the request.

[0211] In some embodiments, the terminal device is a terminal device that supports operation in a first network and a second network.

[0213] In some embodiments, the downlink frequency domain resources used by the first network to provide services and the downlink frequency domain resources used by the second network to provide services at least partially overlap. For example, the first network and the second network use the same downlink frequency domain resources and different time domain resources to provide services to terminal devices in the first network and the second network, respectively. It should be noted that in this case, the downlink frequency domain resources corresponding to the first downlink time domain resources and the downlink frequency domain resources corresponding to the second downlink time domain resources can completely overlap, partially overlap, or not overlap at all; this application does not limit this.

[0220] In some embodiments, the second downlink transmission corresponds to the second HARQ-ACK information, which can be transmitted through the second cell or through the first cell.

[0221] In some embodiments, the first downlink transmission corresponds to the first HARQ-ACK information, and the second downlink transmission corresponds to the second HARQ-ACK information. The first HARQ-ACK information and the second HARQ-ACK information can be transmitted through independent channels; or, the first HARQ-ACK information and the second HARQ-ACK information can be transmitted through the same channel.

[0222] In some embodiments, if the first HARQ-ACK information and the second HARQ-ACK information are transmitted through the same channel, then the first HARQ-ACK information and the second HARQ-ACK information may be encoded independently; or, the first HARQ-ACK information and the second HARQ-ACK information may be jointly encoded.

[0223] In some embodiments, the terminal device sends a request message including one of the following:

[0224] The terminal device sends a request message to the first network device through the first uplink time domain resources of the first cell;

[0225] The terminal device sends a request message to the first network device through the first uplink time domain resources of the second cell;

[0226] The terminal device sends a request message to the second network device through the first uplink time domain resources of the second cell;

[0227] The terminal device sends a request message to the second network device through the first uplink time domain resources of the first cell.

[0228] In some embodiments, the first cell is a cell in a first network, and the second cell is a cell in a second network.

[0229] In some embodiments, if a first network device receives the request information, and the first network device and the second network device are not the same network device, then the first network device forwards the received request information to the second network device. Alternatively, the second network device obtains the request information sent by the terminal device through the first network device.

[0230] In some embodiments, the second network device obtains the request information including one of the following:

[0231] The second network device receives the request information sent by the terminal device through the second uplink time domain resources of the second cell;

[0232] The second network device receives the request information sent by the terminal device through the first uplink time domain resource of the first cell;

[0239] In some embodiments, the system configuration information sent by the second network device includes at least the system configuration information requested by the terminal device.

[0240] As an example, the request information includes instruction information, which is used to indicate mobility management-related configuration information, and the system configuration information includes mobility management-related configuration information.

[0241] As another example, the request information includes indication information for indicating the paging configuration information of the second cell, and the system configuration information includes the paging configuration information of the second cell and the uplink access configuration information of the second cell.

[0242] As another example, the request information includes indication information for indicating the second SSB of the second cell, and the system configuration information includes the second SSB of the second cell.

[0243] In some embodiments, the terminal device receives first indication information sent by the first network device, wherein the first indication information is used to determine at least one of the following: whether the spectrum where the first downlink time domain resource is located supports sharing by multiple networks, whether the first SSB in the first network can be used to assist the terminal device in accessing the second network, and whether the terminal device that supports the second network can access the second network by accessing the first network.

[0244] In some embodiments, the first indication information is carried in at least one of the following: SSB, MIB, PBCH, system message, and RRC message.

[0245] In some embodiments, the first downlink time domain resource is associated with the first uplink time domain resource; and / or, the first downlink time domain resource is associated with the second uplink time domain resource.

[0246] In some embodiments, the association relationship can be used to determine the QCL relationship between the first SSB and the uplink channel or signal carrying request information; and / or, the QCL relationship between the first SSB and the downlink channel or signal carrying system configuration information; and / or, the QCL relationship between the uplink channel or signal carrying request information and the downlink channel or signal carrying system configuration information; and / or, the QCL relationship between the first SSB and the second SSB.

[0247] Understandably, quasi-co-location (QCL) refers to the idea that the large-scale parameters of the channel experienced by a symbol at one antenna port can be inferred from the channel experienced by a symbol at another antenna port. These large-scale parameters can include delay spread, average delay, Doppler spread, Doppler shift, average gain, and spatial reception parameters, among others.

[0248] As an example, the definitions of different QCL type configurations are as follows:

[0249] 'QCL-TypeA': {Doppler shift, Doppler spread, average delay, delay spread};

[0250] 'QCL-TypeB': {Doppler shift, Doppler spread};

[0251] 'QCL-TypeC': {Doppler shift, average delay};

[0252] 'QCL-TypeD': {Spatial Rx parameter}.

[0253] In some embodiments, the association is predefined by the protocol, or the association is configured by a first network device, or the association is configured by a second network device.

[0254] The above solution is described below through two examples.

[0255] Example 1

[0256] Please refer to Figure 6, which illustrates a resource diagram related to an exemplary embodiment of this application. As shown in Figure 6, a first network device in a 5G network transmits a first SSB transmission opportunity on a first time-domain resource (e.g., time-domain resources allocated to 5G network transmission in downlink spectrum shared by 5G and 6G). The first SSB transmission opportunity is associated with a first uplink wake-up signal (UL-WUS) transmission opportunity in a 6G network. The uplink spectrum resource of 6G can be a shared uplink spectrum resource (e.g., uplink spectrum shared by 5G and 6G) ​​or a non-shared uplink spectrum resource (e.g., uplink spectrum dedicated to 6G), and is not limited here.

[0257] The first network device sends a first indication message, which is used to determine at least one of the following: whether the current spectrum resources support sharing by multiple networks, whether the current 5G network supports auxiliary 6G network access, and whether the current 5G network supports 6G terminal device access.

[0258] The first indication information is carried in at least one of the following: SSB, MIB, PBCH, system message, or RRC message.

[0259] The UL-WUS resources included in the first UL-WUS transmission opportunity may be predefined, configured in a 5G network such as the first network device, configured in a 6G network such as the second network device, or determined based on the location of the first SSB transmission opportunity or the SSB resources transmitted in the first SSB transmission opportunity. As an example, the first indication information is used to configure the UL-WUS resources.

[0260] The association between the first SSB transmission opportunity and the first UL-WUS transmission opportunity can be predefined, configured in a 5G network (e.g., a first network device), or configured in a 6G network (e.g., a second network device). As an example, the first indication information is used to configure the association between the first SSB transmission opportunity and the first UL-WUS transmission opportunity. For example, SSB0 in the first SSB transmission opportunity is associated with UL-WUS resource 0 in the first UL-WUS transmission opportunity, and SSB1 in the first SSB transmission opportunity is associated with UL-WUS resource 1 in the first UL-WUS transmission opportunity.

[0261] The terminal device is designed to operate in both 5G and 6G networks. When searching for frequency bands where 5G and 6G networks may be deployed, the terminal device can always detect the network using the initial access method in the 5G network. After accessing the 5G network, the terminal device can determine whether the SSB in the 5G network can be used to assist access to the 6G system based on the received first indication information. Assuming the first indication information configures UL-WUS resources in the 6G network, the terminal device can also determine the association between the first SSB transmission opportunity and the first UL-WUS transmission opportunity in the 5G network according to predefined rules. When the terminal device detects SSB0 in the first SSB transmission opportunity, it can determine the location of the UL-WUS0 associated with SSB0 in the first UL-WUS transmission opportunity based on the association. Further, the terminal device can send a request signal on UL-WUS0 to request a second network device in the 6G network to send a 6G system message. After detecting the request signal on UL-WUS0, the second network device can send a 6G system message to the terminal device through 6G downlink time domain resources.

[0262] Terminal devices can operate in either 5G or 6G networks. For example, when a terminal device needs downlink transmission, a first network device can schedule downlink transmission for the terminal device using 5G downlink time domain resources, while a second network device can schedule downlink transmission for the terminal device using 6G downlink time domain resources.

[0263] Example 2

[0264] Please refer to Figure 7, which illustrates a resource diagram related to another exemplary embodiment of this application. As shown in Figure 7, a first network device in a 5G network transmits a first SSB transmission opportunity on a first time domain resource (e.g., time domain resources allocated to 5G network transmission in the downlink spectrum shared by 5G and 6G), wherein the first SSB transmission opportunity is associated with a first PRACH transmission opportunity in the 5G network.

[0265] The first network device sends a first indication message, which is used to determine at least one of the following: whether the current spectrum resources support sharing by multiple networks, whether the current 5G network supports auxiliary 6G network access, and whether the current 5G network supports 6G terminal device access.

[0266] The first indication information is carried in at least one of the following: SSB, MIB, PBCH, system message, or RRC message.

[0267] The first network device is configured with a first RO set, which is used to support assisted 6G network access. When a terminal device transmits PRACH to the first or second network device through resources in the first RO set, it can be considered that the terminal device has sent a request message to the network device. The association between the first SSB transmission opportunity and the first RO set is the same as the mapping relationship between SSB transmission opportunities and RO resources in a 5G network.

[0268] The terminal device is designed to operate in both 5G and 6G networks. When searching for frequency bands where 5G and 6G networks may be deployed, the terminal device can always detect the network using the initial access method in the 5G network. After the terminal device accesses the 5G network, it can determine whether a Service Streaming Bus (SSB) in the 5G network can be used to assist access to the 6G system based on the received first indication information. Assuming the first indication information configures a first set of ROs supporting assisted 6G network access, when the terminal device detects SSB0 in the first SSB transmission opportunity, it can determine the location of the RO0 associated with SSB0 in the first RO set based on the association relationship. Further, the terminal device can send a request signal (PRACH) on RO0 to request a second network device in the 6G network to send a 6G system message. After detecting the request signal on RO0, the second network device can send the 6G system message to the terminal device using 6G downlink time domain resources. Alternatively, after the first network device detects the request signal on RO0, it can forward the request signal to the second network device. After the second network device obtains the request signal, it can send a 6G system message to the terminal device through 6G downlink time domain resources.

[0269] Terminal devices can operate in either 5G or 6G networks. For example, when a terminal device needs downlink transmission, a first network device can schedule downlink transmission for the terminal device using 5G downlink time domain resources, while a second network device can schedule downlink transmission for the terminal device using 6G downlink time domain resources.

[0270] To address the scarcity of spectrum resources, 5G and 6G networks may share the same spectrum. The solution provided in this application allows a 6G terminal device to initially receive a Service Serving Block (SSB) from the 5G network device upon initial access. Based on the SSB sent by the 5G network device, the 6G terminal device then initiates a request signal for system configuration information from the 6G network device. This enables the 6G network to also provide services to the terminal device, thereby avoiding or mitigating interference in communication signal transmission between the two networks sharing spectrum resources, thus improving the effectiveness and reliability of information transmission. Furthermore, the system configuration information in the 6G network does not need to be continuously transmitted; it is only transmitted based on the terminal device's request, resulting in network energy savings.
