[0035] Traditional communication systems typically support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication but also, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, or vehicle-to-everything (V2X) communication. The embodiments of this application can also be applied to these communication systems.

[0037] The communication system in this application embodiment can be applied to unlicensed spectrum, wherein unlicensed spectrum can also be considered as shared spectrum; or, the communication system in this application embodiment can also be applied to licensed spectrum, wherein licensed spectrum can also be considered as non-shared spectrum.

[0038] Communication system scenarios include non-terrestrial network (NTN) systems and terrestrial network (TN) systems. NTN typically uses satellite communication to provide communication services to terrestrial users. Current NTN systems include NR-NTN and IoT-NTN (Internet of Things NTN) systems, and other NTN systems may be included in the future.

[0039] For example, Figure 1 is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. As shown in Figure 1, the communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120. The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminal devices located within that coverage area.

Wireless communication is possible between the terminal device 301 and the satellite 302, and communication is possible between the satellite 302 and the base station 303. The network formed between the terminal device 301, the satellite 302, and the base station 303 can also be called an NTN. In the architecture of the communication system shown in Figure 3, the satellite 302 may not have the function of a base station, and communication between the terminal device 301 and the base station 303 requires relaying through the satellite 302. In this system architecture, the base station 303 can be referred to as a network device. In some embodiments of this application, the communication system may include multiple base stations 303, each base station 303 can communicate with one or more satellites 302, and the coverage area of ​​each satellite 302 may include other numbers of terminal devices; this application does not limit this aspect.

[0043] In future communication systems such as B5G (Beyond 5G) or 6G, there may also be distributed multiple-input multiple-output (MIMO, also known as distributed antenna system) scenarios and / or massive multiple-input multiple-output (MIMO, also known as massive antenna matrix system) scenarios. In some cases, distributed MIMO and / or massive MIMO can 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.

[0044] For example, Figure 4 is a schematic diagram of another communication system architecture provided in an embodiment of this application. This system architecture includes distributed antenna ports (or distributed antenna port clusters), and / or a central processing unit (CPU), and / or a switch module. As shown in Figure 4, the communication system may include multiple distributed antenna ports (or distributed antenna port clusters), and different distributed antenna ports (or distributed antenna port clusters) are connected to the CPU through a switch module. The terminal device selects a suitable distributed antenna port (or distributed antenna port cluster) to serve it based on its geographical location.

In some embodiments of this application, the communication system may include other numbers of CPUs, and / or other numbers of switch modules, and / or other numbers of distributed antenna ports (or distributed antenna port clusters), and / or other numbers of terminal devices. This application does not limit the specific number of terminal devices.

[0045] For example, Figure 5 is a schematic diagram of another communication system architecture provided in an embodiment of this application. Referring to Figure 5, it includes a terminal device 501 and a satellite cluster 502, which can communicate wirelessly. The network formed between the terminal device 501 and the satellite cluster 502 can also be called an NTN. In the architecture of the communication system shown in Figure 5, at least one satellite in the satellite cluster 502 (e.g., a satellite located at the center) can have the function of a base station, and the terminal device 501 and the satellite cluster 502 can communicate directly. In this system architecture, a satellite with base station function can be referred to as a network device. In some embodiments of this application, the communication system may include multiple satellite clusters, and / or each satellite cluster includes one or more network devices, and / or the coverage area of ​​each satellite cluster or each network device may include other numbers of terminal devices; this application does not limit this.

Referring to Figure 6, the system includes a terminal device 601, a satellite cluster 602, and a base station 603. Wireless communication is possible between the terminal device 601 and the satellite cluster 602, and communication is possible between the satellite cluster 602 and the base station 603. The network formed between the terminal device 601, the satellite cluster 602, and the base station 603 can also be called an NTN. In the communication system architecture shown in Figure 6, the satellite cluster 602 may not have the function of a base station; communication between the terminal device 601 and the base station 603 requires relaying through the satellite cluster 602. In this system architecture, the base station can be referred to as a network device. In some embodiments of this application, the communication system may include multiple satellite clusters, and / or one network device may be associated with one or more satellite clusters, and / or may include multiple network devices, and / or the coverage area of ​​each network device may include other numbers of terminal devices. This application does not limit this aspect.

[0047] The terminal device mentioned in the embodiments of this application may refer to UE (User Equipment), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, user agent, or user device. Optionally, the terminal device 10 may also be a cellular phone, cordless phone, SIP (Session Initiation Protocol) phone, WLL (Wireless Local Loop) station, PDA (Personal Digital Assistant), handheld device with wireless communication function, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in 5GS (5th Generation System), or terminal device in the future evolved PLMN (Public Land Mobile Network), etc., and the embodiments of this application are not limited thereto. For ease of description, the devices mentioned above are collectively referred to as terminal devices. In the embodiments of this application, "terminal device" and "UE" are usually used interchangeably, but those skilled in the art will understand that they can express the same meaning.

[0048] The network devices mentioned in this application embodiment can be access network devices, located on the ground or on a satellite. An access network device is a device deployed in an access network to provide wireless communication functions for terminal devices. Access network devices can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the names of devices with access network device functions may differ; for example, in a 5G NR system, they are called gNodeB or gNB. As communication technologies evolve, the name "access network device" may change. For ease of description, in this application embodiment, the aforementioned devices providing wireless communication functions for terminal devices are collectively referred to as access network devices. Optionally, a communication relationship can be established between the terminal device and the core network device through the access network device.

[0049] The "5G NR system" in this application embodiment can also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in this application embodiment can be applied to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (such as 6G systems), as well as other communication systems such as NB-IoT (Narrow Band Internet of Things) systems. This application does not limit these applications.

[0050] In this embodiment, the network device can provide services to a cell. The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0051] Before introducing the technical solution of this application, some related technical knowledge involved in this application will be introduced and explained. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0052] 1. Initial Access in a 5G NR System

[0053] In 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. The detected SSBs provide time and frequency synchronization, radio frame timing, and a Cell ID (Identity Document).

[0054] 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.

[0055] After detecting an SSB, the terminal device can determine the configuration of the Type0-PDCCH (Physical Downlink Control Channel) CSS (Cyclic Shift Sounding) set through the MIB (Master Information Block) message in the SSB. The terminal device can receive the network device's scheduling of SIB (System Information Block) 1 messages by listening to the Type0-PDCCH CSS set. Both the MIB and SIB1 messages include the serving cell's system configuration information. Furthermore, the terminal device can receive the network device's scheduling of other system messages besides SIB1 messages by listening to the Type0A-PDCCH CSS set, receive the network device's scheduling of paging messages by listening to the Type2-PDCCH CSS set, and receive the Paging Early Indication (PEI) information for paging messages sent by the network device by listening to the Type2A-PDCCH CSS set.

[0056] The terminal device can also obtain the resource configuration for PRACH (Physical Random Access Channel) transmission opportunities (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 (also known as PRACH). If two-step RACH (Random Access Channel) transmission is supported, the resource configuration during the random access process also includes PUSCH resource configuration, also known as PUSCH transmission opportunities (PO). In the two-step RACH, message A (MsgA) includes PRACH and MsgA PUSCH; RO is the time-frequency resource used to carry PRACH, and PO is the time-frequency resource used to carry MsgA PUSCH.

[0057] A key feature of the NR system is its support for downlink multi-beaming, where different SSBs are associated with different beams. Before a terminal device initiates random access, it measures and evaluates the signal quality of the cell and the signal strength of each SSB within it. If the detected SSB signal strength exceeds a threshold, the strongest or relatively strong SSB is identified. For example, if the terminal device determines SSB#1 as the strongest SSB, it determines the corresponding PRACH transmission opportunity for SSB#1 as RO#1 based on the mapping relationship between SSBs and ROs, and transmits the PRACH on RO#1. If the network device successfully receives the PRACH, it can determine the SSB selected by the terminal device based on the resource information from the successful reception. For instance, the network device can determine that the PRACH is associated with SSB#1 based on the association relationship, and thus determine the beam information for subsequent communication based on SSB#1.

[0058] The four-step random access procedure (also known as the Type-1 Random Access Procedure or the first type of random access procedure) may include the following steps:

[0059] The first step is for the terminal device to send a PRACH (also known as Msg1) to the network device on the RO of the uplink initial BWP (Bandwidth Part).

[0060] The second step involves the network device, upon detecting Msg1, sending a PDCCH scrambled with RA-RNTI (Radio Network Temporary Identifier) ​​to the terminal device via resources in the Type1-PDCCH common search space (CSS) on the downlink initial BWP. The PDSCH (Physical Downlink Shared Channel) scheduled by this PDCCH may include the Random Access Response (RAR, also known as Msg2) corresponding to the PRACH sent by the terminal device. Correspondingly, the terminal device uses RA-RNTI to detect the PDCCH on the Type1-PDCCH CSS on the downlink initial BWP, and upon detection, determines whether the PDSCH scheduled by this PDCCH includes the RAR sent by the network device. The RAR may include information such as the uplink grant, timing advance command (TA command), and temporary RNTI (TC-RNTI) from message 3 (Msg3). The Type1-PDCCH CSS is configured by the network device through system messages and / or higher-layer parameters.

[0061] Third, after receiving the RAR, the terminal device sends a PUSCH on the uplink resources indicated by the RAR, which carries message 3 (Msg3). This step supports HARQ retransmission. If the network device does not receive Msg3 correctly, it can use a PDCCH with TC-RNTI scrambling to schedule a retransmission of Msg3.

[0062] In the fourth step, the network device sends a PDSCH to the terminal device. This PDSCH carries message 4 (Msg4), which includes a contention resolution message. This step supports HARQ (Hybrid Automatic Repeat reQuest) retransmission. If the terminal device does not correctly receive Msg4, the network device can use a PDCCH with TC-RNTI scrambling to schedule the retransmission of Msg4. If the terminal device correctly receives Msg4 and determines that it is its message, it sends an ACK message back to the network device, indicating that the random access procedure for the terminal device is successful. Otherwise, the random access procedure fails, and the terminal device needs to initiate the random access procedure again from the first step.

[0063] A two-step random access procedure (also known as a Type-2 Random Access Procedure or Type II Random Access Procedure) may include the following steps:

[0064] The first step is for the terminal device to send message A (MsgA) to the network device on the RO and PO of the uplink initial BWP, or in other words, for the terminal device to send PRACH and MsgA PUSCH to the network device on the RO and PO of the uplink initial BWP.

[0065] In the second step, after detecting MsgA, the network device sends a MsgB-RNTI-scrambled PDCCH to the terminal device through resources in the Type1-PDCCH common search space (CSS) on the downlink initial BWP. The PDSCH scheduled for this PDCCH may include the random access response (also known as MsgB) corresponding to MsgA sent by the terminal device. If the network device only detects MsgA PRACH and does not receive MsgA PUSCH, the PDSCH scheduled for this PDCCH may include the fallback RAR corresponding to MsgA PRACH sent by the terminal device. Accordingly, the terminal device uses MsgB-RNTI to detect PDCCH on the Type1-PDCCH CSS on the downlink initial BWP, and after detecting PDCCH, determines whether it includes a success RAR or a fallback RAR sent by the network device based on the PDSCH scheduled for this PDCCH. If the terminal device correctly receives the success RAR, the terminal device sends ACK information back to the network device, and the random access procedure of the terminal device is successful. Alternatively, if the terminal device receives a rollback RAR, it sends Msg3 on the uplink resources indicated by the rollback RAR, and the two-step random access procedure falls back to a four-step random access procedure. Alternatively, if the terminal device does not receive any RAR, the random access procedure fails, and the terminal device needs to initiate the random access procedure again from step one.

[0066] Because spectrum resources are scarce, in some scenarios, such as when 5G (Fifth Generation Mobile Networks) and 6G network equipment are located at the same site or even the same network device, it may be necessary for 5G and 6G networks to share spectrum resources for communication transmission. In scenarios where spectrum resources are shared, how to avoid or mitigate interference in communication signal transmission between the two networks sharing spectrum resources to improve the effectiveness and reliability of information transmission remains unclear.

[0067] Please refer to Figure 7, which shows a flowchart of a wireless communication method provided in an embodiment of this application, which is performed by a terminal device. The method includes the following step 710.

[0068] Step 710: The terminal device receives first configuration information from the first network device. The first configuration information is used to determine the first uplink resource in the first cell. The first uplink resource is used by the first terminal device, which has the ability to work in the second network, to send the first uplink channel or signal. The first cell is a cell in the first network, and the first network device is a network device in the first cell.

[0069] Accordingly, the first network device sends the first configuration information to the terminal device.

[0070] In some embodiments, the first network device is a network device of a first cell, and the first cell is a cell in a first network. In some embodiments, the second network device is a network device of a second cell, and the second cell is a cell in a second network.

[0071] In some embodiments, the first network device and the second network device are the same network device. For example, when the first network and the second network share a site, the first network device can provide services to both the first and second networks. For instance, the first network device can simultaneously provide services to both 5G and 6G networks. As another example, the first network device can simultaneously provide services to both NTN (Non-Terrestrial Network) and TN (Terrestrial Network) networks.

[0072] In some embodiments, the first network device and the second network device are different network devices. For example, the first network device provides services for a 5G network, and the second network device provides services for a 6G network; information exchange between the first and second network devices is performed through an interface between the network devices. For example, the first network device provides services for an NTN network, and the second network device provides services for a TN network; information exchange between the first and second network devices is performed through an interface between the network devices.

[0073] In some embodiments, the first network and the second network share spectrum resources. In some embodiments, the first network and the second network share uplink spectrum resources and / or downlink spectrum resources.

[0074] In some embodiments, there is an overlap between the spectrum resources used by the first network to provide services and the spectrum resources used by the second network to provide services.

[0075] In some embodiments, the downlink frequency domain resources used by the first network to provide services partially or completely overlap with the downlink frequency domain resources used by the second network to provide services. For example, as shown in FIG8(a), frequency domain resource 810 is the downlink frequency domain resource used by the first network to provide services, and frequency domain resource 820 is the downlink frequency domain resource used by the second network to provide services, with frequency domain resource 810 and frequency domain resource 820 partially overlapping; as shown in FIG8(b), 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 are both frequency domain resource 830.

[0076] In some embodiments, the uplink frequency domain resources used by the first network to provide services and the uplink frequency domain resources used by the second network to provide services partially or completely overlap. For example, as shown in FIG8(a), frequency domain resource 810 is the uplink frequency domain resource used by the first network to provide services, and frequency domain resource 820 is the uplink frequency domain resource used by the second network to provide services, with frequency domain resources 810 and 820 partially overlapping; as shown in FIG8(b), the uplink frequency domain resources used by the first network to provide services and the uplink frequency domain resources used by the second network to provide services are both frequency domain resource 830.

[0077] In some embodiments, the downlink frequency domain resources used by the first network to provide services and the uplink frequency domain resources used by the second network to provide services partially or completely overlap. For example, as shown in FIG8(a), frequency domain resource 810 is the downlink frequency domain resource used by the first network to provide services, and frequency domain resource 820 is the uplink frequency domain resource used by the second network to provide services, with frequency domain resources 810 and 820 partially overlapping; as shown in FIG8(b), the downlink frequency domain resources used by the first network to provide services and the uplink frequency domain resources used by the second network to provide services are both frequency domain resource 830.

[0078] In some embodiments, the uplink 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 partially or completely overlap. For example, as shown in FIG8(a), frequency domain resource 810 is the uplink frequency domain resource used by the first network to provide services, and frequency domain resource 820 is the downlink frequency domain resource used by the second network to provide services, with frequency domain resources 810 and 820 partially overlapping; as shown in FIG8(b), the uplink 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 are both frequency domain resource 830.

[0079] In some embodiments, the spectrum resources used by the first network to provide services belong to the same frequency band as the spectrum resources used by the second network to provide services, but the two do not overlap.

[0080] 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 belong to the same frequency band, and 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 do not overlap. For example, the downlink frequency domain resources used by the first network to provide services are a first downlink BWP, and the downlink frequency domain resources used by the second network to provide services are a second downlink BWP. The first downlink BWP and the second downlink BWP do not overlap at all in the frequency domain. For example, as shown in FIG9, frequency domain resource 910 is the downlink frequency domain resource used by the first network to provide services, and frequency domain resource 920 is the downlink frequency domain resource used by the second network to provide services. Both frequency domain resources 910 and 920 belong to frequency band 900, and there is no overlap between frequency domain resources 910 and 920.

[0081] In some embodiments, the uplink frequency domain resources used by the first network to provide services and the uplink frequency domain resources used by the second network to provide services belong to the same frequency band, and the uplink frequency domain resources used by the first network to provide services and the uplink frequency domain resources used by the second network to provide services do not overlap. For example, the uplink frequency domain resources used by the first network to provide services are a first uplink BWP, and the uplink frequency domain resources used by the second network to provide services are a second uplink BWP. The first uplink BWP and the second uplink BWP do not overlap at all in the frequency domain. For example, as shown in FIG9, frequency domain resource 910 is the uplink frequency domain resource used by the first network to provide services, and frequency domain resource 920 is the uplink frequency domain resource used by the second network to provide services. Both frequency domain resources 910 and 920 belong to frequency band 900, and there is no overlap between frequency domain resources 910 and 920.

[0082] In some embodiments, the downlink frequency domain resources used by the first network to provide services and the uplink frequency domain resources used by the second network to provide services belong to the same frequency band, and the downlink frequency domain resources used by the first network to provide services and the uplink frequency domain resources used by the second network to provide services do not overlap. For example, the downlink frequency domain resources used by the first network to provide services are a first downlink BWP, and the uplink frequency domain resources used by the second network to provide services are a second uplink BWP. The first downlink BWP and the second uplink BWP do not overlap at all in the frequency domain. For example, as shown in FIG9, frequency domain resource 910 is the downlink frequency domain resource used by the first network to provide services, and frequency domain resource 920 is the uplink frequency domain resource used by the second network to provide services. Both frequency domain resources 910 and 920 belong to frequency band 900, and there is no overlap between frequency domain resources 910 and 920.

[0083] In some embodiments, the uplink 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 belong to the same frequency band, and the uplink 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 do not overlap. For example, the uplink frequency domain resources used by the first network to provide services are a first uplink BWP, and the downlink frequency domain resources used by the second network to provide services are a second downlink BWP. The first uplink BWP and the second downlink BWP do not overlap at all in the frequency domain. For example, as shown in FIG9, frequency domain resource 910 is the uplink frequency domain resource used by the first network to provide services, and frequency domain resource 920 is the downlink frequency domain resource used by the second network to provide services. Both frequency domain resources 910 and 920 belong to frequency band 900, and there is no overlap between frequency domain resources 910 and 920.

[0084] In some embodiments, the first network is a 5G network and the second network is a 6G network.

[0085] In some embodiments, the first network is a TN network and the second network is an NTN network.

[0086] In some embodiments, the terminal device has the capability to operate in a first network and / or a second network. In some embodiments, the terminal device has the capability to operate in a first network. In some embodiments, the terminal device has the capability to operate in a second network. In some embodiments, the terminal device has the capability to operate in both a first network and a second network.

[0087] In some embodiments, the first configuration information is used to configure a first uplink resource set in a first cell. The first uplink resource set is used by a terminal device capable of operating in a second network to transmit a first uplink channel or signal. The first uplink resource set includes one or more first uplink resources.

[0088] In some embodiments, the first configuration information is used to configure the first uplink resource in the first cell.

[0089] In some embodiments, the first configuration information is a first system message. In some embodiments, the first configuration information is first RRC configuration information.

[0090] In some embodiments, the method further includes step 720 (not shown in the figure).

[0091] Step 720: The terminal device sends a first uplink channel or signal through the first uplink resource. The first uplink channel or signal is used to determine that the terminal device has the ability to work in the second network.

[0092] Accordingly, the first network device receives the first uplink channel or signal through the first uplink resource.

[0093] In some embodiments, a first indication information is carried in the first uplink channel or signal, the first indication information being used to indicate that the terminal device has the capability to operate in the second network.

[0094] In some embodiments, the first uplink resource is used to implicitly indicate that the terminal device has the capability to operate in the second network, or the first uplink channel or signal is used to implicitly indicate that the terminal device has the capability to operate in the second network. For example, the terminal device can only transmit the first uplink channel or signal through the first uplink resource if it has the capability to operate in the second network; correspondingly, after receiving the first uplink channel or signal through the first uplink resource, the first network device can determine that the terminal device has the capability to operate in the second network.

[0095] In some embodiments, the method further includes step 730 (not shown in the figure).

[0096] Step 730: The terminal device receives second configuration information sent by the first network device. The second configuration information is used to configure the second network.

[0097] Accordingly, the first network device sends the second configuration information.

[0098] In some embodiments, the first network device sends second configuration information to the terminal device when it determines that the terminal device has the capability to operate in the second network.

[0099] In some embodiments, the second configuration information is used to configure at least one of the following: system messages of the second cell in the second network, cell list in the second network, paging configuration messages in the second network, RNTI of the terminal device in the second network, and cell handover configuration messages.

[0100] In some embodiments, the cell handover configuration message is used to hand over the terminal device to a cell in the second network. In some embodiments, the paging configuration message in the second network can be a paging configuration message for a second cell in the second network.

[0101] In some embodiments, after receiving the second configuration information, the terminal device may also perform at least one of the following steps 1 to 5.

[0102] Step 1: The terminal device sends an ACK message. Correspondingly, the first network device receives the ACK message.

[0103] Step 2: The terminal device accesses the second cell in the second network according to the second configuration information.

[0104] In some embodiments, when the second configuration information is used to configure the system messages of the second cell in the second network, the terminal device accesses the second cell in the second network according to the system messages of the second cell.

[0105] Step 3: The terminal device performs mobility management on the cells in the second network according to the second configuration information.

[0106] In some embodiments, when the second configuration information is used to configure a cell list in the second network, the terminal device performs mobility management on the cells in the second network based on the cell list in the second network.

[0107] Step 4: The terminal device listens for paging messages in the second network according to the second configuration information.

[0108] In some embodiments, when the second configuration information is used to configure paging configuration messages in the second network, the terminal device listens for paging messages in the second network according to the paging configuration message.

[0109] In some embodiments, when the second configuration information is used to configure the paging configuration message of the second cell in the second network, the terminal device listens for the paging message in the second cell according to the paging configuration message.

[0110] Step 5: The terminal device switches to the second network according to the second configuration information.

[0111] In some embodiments, when the second configuration information is used to configure the cell handover configuration message, the terminal device switches to a cell in the second network according to the cell handover configuration message.

[0112] In some embodiments, the method further includes step 740 (not shown in the figure).

[0113] Step 740: The terminal device receives third configuration information sent by the first network device. The third configuration information is used to determine whether the first terminal device supports reporting a first capability, wherein the first capability includes the ability to work in the second network.

[0114] Accordingly, the first network device sends the third configuration information.

[0115] It is understood that step 740 may be performed before step 710, or step 740 may be performed after step 710, or steps 740 and 710 may be performed simultaneously; this application does not limit this.

[0116] In some embodiments, the third configuration information is used to determine whether the first terminal device is supported in reporting the first capability, including: the third configuration information is used to determine whether the first terminal device is supported in accessing the first cell in the first network; or, the third configuration information is used to determine whether the first terminal device is supported in accessing the second network through the first network; or, the third configuration information is used to determine whether the first network device supports switching the first terminal device from the first network to the second network.

[0117] For example, the third configuration information is used to indicate whether access to the second network by the first terminal device through the first cell in the first network is supported. For example, the third configuration information is used to indicate whether switching of the first terminal device, which is capable of operating in the second network, from the first cell in the first network to the second cell in the second network is supported.

[0118] In some embodiments, the third configuration information is used to determine whether the first terminal device is supported in reporting the first capability, including: when the first network device sends the third configuration information, the third configuration information is used to indicate that the first terminal device is supported in reporting the first capability; and / or, when the first network device does not send the third configuration information, the third configuration information is used to indicate that the first terminal device is not supported in reporting the first capability.

[0119] In some embodiments, the third configuration information is used to determine whether the first terminal device is supported in reporting the first capability, including: when the third configuration information indicates that the first terminal device is supported in reporting the first capability, or indicates that the first terminal device is true, or indicates a preset value such as 1; and / or, when the third configuration information indicates that the first terminal device is disabled, indicates that the first terminal device is false, or indicates another preset value such as 0, the third configuration information is used to indicate that the first terminal device is not supported in reporting the first capability.

[0120] In some embodiments, the third configuration information is carried in the main message block (MIB) or the system message block (SIB). For example, the first network is a 5G network, the second network is a 6G network, and the first terminal device is capable of operating in the 6G network. The third configuration information includes 1 bit, which is carried in the MIB or SIB1 transmitted on the first cell in the 5G network. When this bit indicates 1, or when the bit is carried in the MIB or SIB1, it indicates that the first terminal device can access the 6G network through the first cell; or, when this bit indicates 0, or when the bit is not carried in the MIB or SIB1, it indicates that the first terminal device cannot access the 6G network through the first cell.

[0121] The technical solution provided in this application embodiment allows a first network device to configure a first uplink resource for a first terminal device capable of operating in a second network. This enables the first terminal device to send a first uplink channel or signal to the first network device. When accessing the first network, the terminal device reports to the first network device an indication that it is capable of operating in the second network. This allows the first network device to decide whether to switch the terminal device to the second network to obtain better communication efficiency. This avoids or reduces interference in communication signal transmission between two networks sharing spectrum resources, thereby improving the effectiveness and reliability of information transmission. It also reduces the resources required for initial access of terminal devices capable of operating in the second network, improving the utilization rate of communication resources.

[0122] In some embodiments, the first uplink channel or signal is an uplink channel or signal transmitted during a random access process between a terminal device and a first network device. Exemplarily, the first uplink channel or signal is used to carry Msg1, or Msg3, or MsgA. It is understood that the random access process may or may not be based on PRACH. Therefore, exemplarily, in the case where the random access process is not based on PRACH (e.g., RACH-less), the first uplink resource may be a pre-configured uplink resource in the random access process, and the first uplink channel or signal may be a CG-PUSCH transmitted on the pre-configured grant (CG) uplink resource in that random access process; or, the first uplink resource may be a dynamically scheduled uplink resource, such as one allocated by DCI, in the random access process, and the first uplink channel or signal may be a PUSCH transmitted on the DCI-allocated uplink resource in that random access process.

[0123] In some embodiments, the first uplink channel or signal is an uplink channel or signal transmitted on pre-configured authorized uplink resources. For example, the first uplink channel or signal is a CG-PUSCH. In some embodiments, the first uplink channel or signal is an uplink channel or signal transmitted on dynamically scheduled uplink resources. For example, the first uplink channel or signal is a DCI-scheduled PUSCH.

[0124] In some embodiments, the first configuration information is used to configure a first uplink resource set, which includes one or more first uplink resources.

[0125] In some embodiments, the first configuration information is further used to configure a second uplink resource set, which includes one or more second uplink resources. The second uplink resources are used for a second terminal device that does not have the ability to work in the second network to access the first network.

[0126] In some embodiments, the terminal device has the capability to operate in a second network, including one of the following:

[0127] The terminal device has the capability to operate in a second network;

[0128] The terminal device has the capability to operate in the second network, and the terminal device requests the second network;

[0129] The terminal device requests access to the second network.

[0130] In some embodiments, the terminal device does not have the ability to operate in a second network, including one of the following:

[0131] The terminal device does not have the capability to operate in a second network;

[0132] The terminal device has the capability to operate in the second network, but the terminal device does not request access to the second network;

[0133] The terminal device does not request access to the second network;

[0134] The terminal device requests access to the first network.

[0135] In some embodiments, if the terminal device is capable of operating in the second network and wants to access the second network, the terminal device sends a first uplink channel or signal to the first network device through the first uplink resource, and the first network device sends second configuration information to the terminal device. That is, the terminal device only selects the first uplink resource to send the first uplink channel or signal when it is capable of operating in the second network and wants to access it, indicating that the terminal device is requesting the first network device to configure it for the second network. Correspondingly, after receiving the first uplink channel or signal through the first uplink resource, the first network device sends the second configuration information to the terminal device.

[0136] In some embodiments, if a terminal device is capable of operating in a second network but does not wish to access the second network, the terminal device sends a first uplink channel or signal to the first network device through the second uplink resources, and the first network device does not send the second configuration information to the terminal device. That is, even if the terminal device is capable of operating in a second network, it can still choose to send the first uplink channel or signal using the second uplink resources if it does not wish to access the second network.

[0137] In some embodiments, if the terminal device has the capability to operate in a second network, it sends a first uplink channel or signal to the first network device through the first uplink resource. After receiving the first uplink channel or signal through the first uplink resource, the first network device may send second configuration information to the terminal device or may not send the second configuration information. That is, as long as the terminal device has the capability to operate in a second network, it should select the first uplink resource to send the first uplink channel or signal, thereby reporting this capability to the base station. After the terminal device reports its capability, whether to configure the second network for the terminal device is determined by the first network device.

[0138] In some embodiments, if the terminal device does not have the capability to operate in the second network, the terminal device sends a first uplink channel or signal to the first network device through the second uplink resource, and the first network device does not send the second configuration information to the terminal device.

[0139] The following will provide exemplary descriptions of the first uplink channel or signal used to carry Msg1, MsgA and Msg3, and the first uplink signal or signal including PUSCH.

[0140] 1. The first uplink channel or signal is used to carry Msg1

[0141] In some embodiments, the first uplink channel or signal is an uplink channel or signal in a first type of random access procedure. In some embodiments, in a first type of random access procedure, the first uplink channel or signal includes a first PRACH. In some embodiments, the first type of random access procedure is a four-step random access procedure.

[0142] In some embodiments, the first configuration information is used to configure a first uplink resource set, which includes one or more first uplink resources. In some embodiments, the first uplink resource set includes a first random access resource set, which includes one or more first uplink resources, such as a first PRACH resource.

[0143] In some embodiments, the first configuration information is used to configure a random access resource set, such as a RO set, in the first cell. This random access resource set includes a first random access resource set, such as a first RO set, which is used by terminal devices capable of operating in the second network to transmit a first uplink channel or signal. The first uplink resource is a resource in the first random access resource set. In other words, the first network device configures a first random access resource set specifically for terminal devices capable of operating in the second network to initiate random access.

[0144] In some embodiments, the first configuration information is a first system message. In some embodiments, the first configuration information is first RRC configuration information.

[0145] In some embodiments, the first uplink resource includes PRACH resources, for example, the first uplink resource includes a first PRACH resource, and the first uplink channel or signal includes a first PRACH.

[0146] In some embodiments, the first configuration information is used to configure a first random access resource set in a first cell, the first random access resource set including one or more first uplink resources. In some embodiments, the first configuration information is used to configure at least one of the following: time-domain resources of ROs in the first random access resource set, frequency-domain resources of ROs in the first random access resource set, and sequence resources of PRACHs in the first random access resource set.

[0147] In some embodiments, the first configuration information is further used to configure a second uplink resource set, which includes one or more second uplink resources. In some embodiments, the second uplink resource set includes a second random access resource set, which includes one or more second uplink resources, such as a second PRACH resource.

[0148] In some embodiments, the first configuration information is used to configure a second random access resource set in the first cell, such as a second RO set, which is used for terminal devices that do not have the ability to operate in the second network to send uplink channels or signals.

[0149] In some embodiments, PRACH resources include at least one of the following:

[0150] RO's temporal resources;

[0151] RO's frequency domain resources;

[0152] PRACH sequence resources.

[0153] In some embodiments, the sequence resource of PRACH is the identifier of the PRACH sequence.

[0154] During the four-step random access process, the first network device can configure a first uplink resource and a second uplink resource for the terminal device. The first uplink resource is used for the terminal device that has the ability to work in the second network to send a first uplink channel or signal, and the second uplink resource is used for the terminal device that does not have the ability to work in the second network to send a first uplink channel or signal.

[0155] In some embodiments, the first configuration information is used to configure a first uplink resource set and a second uplink resource set. The first uplink resource set includes one or more first uplink resources, and the second uplink resource set includes one or more second uplink resources. In some embodiments, the first uplink resources are used by terminal devices capable of operating in a second network to transmit uplink channels or signals. In some embodiments, the second uplink resources are used by terminal devices not capable of operating in a second network to transmit uplink channels or signals.

[0156] For example, the first uplink resource set is a first RO set, which includes a first PRACH resource; the second uplink resource set is a second RO set, which includes a second PRACH resource.

[0157] In some embodiments, when a terminal device sends a first PRACH to a first network device via a first PRACH resource in a first RO set, the first network device, upon receiving the first PRACH, can determine that the terminal device has the capability to operate in the second network. In some embodiments, when a terminal device sends a second PRACH to a first network device via a second PRACH resource in a second RO set, the first network device, upon receiving the second PRACH, can determine that the terminal device does not have the capability to operate in the second network.

[0158] In some embodiments, the terminal device sends a first PRACH via a first uplink resource. Correspondingly, the first network device detects the first PRACH via the first uplink resource.

[0159] In some embodiments, the first network device sends a first PDSCH and / or a first DCI to the terminal device. The first DCI is used to schedule the first PDSCH, and the first PDSCH is used to carry response information. For example, the first PDSCH is used to carry RAR. Accordingly, the terminal device receives the first PDSCH and / or the first DCI.

[0160] It is understandable that the response information is the response information corresponding to the first uplink channel or signal.

[0161] For example, the first DCI is a RA-RNTI scrambling DCI, and the first PDSCH carries the RAR corresponding to the first PRACH.

[0162] In some embodiments, if the terminal device transmits a first uplink channel or signal through a first uplink resource, the terminal device receives a first PDSCH and / or a first DCI, and determines second configuration information through the first PDSCH and / or the first DCI. In some embodiments, during a first type of random access process, if the first uplink channel or signal includes a first PRACH, the first PDSCH is used to carry response information, which includes RAR.

[0163] In some embodiments, the terminal device receives second configuration information sent by the first network device through a second downlink resource in the first cell. The second configuration information is used to configure the second network. For example, the terminal device receives a first PDSCH and / or a first DCI through this second downlink resource.

[0164] In some embodiments, during a first type of random access process, the terminal device receives a first PDSCH and / or a first DCI. The first PDSCH is used to carry response information and / or second configuration information, and the first DCI is used to schedule the first PDSCH. The first DCI may or may not include the second configuration information. The response information includes RAR.

[0165] For example, the terminal device receives a first DCI and a first PDSCH scheduled by the first DCI. The first PDSCH is used to carry response information. The first DCI includes second configuration information, and the first PDSCH does not carry the second configuration information; or, the first DCI does not include the second configuration information, and the first PDSCH is used to carry the second configuration information; or, the first DCI includes part of the second configuration information, and the first PDSCH is used to carry another part of the second configuration information.

[0166] In some embodiments, the first PDSCH is used to carry response information and second configuration information, which can be implemented as follows: the first PDSCH is used to carry response information, and the response information includes the second configuration information; or, the first PDSCH is used to carry second configuration information, and the second configuration information includes response information; or, the first PDSCH is used to carry response information and second configuration information respectively.

[0167] In other words, during the first type of random access process, after sending the first PRACH, the terminal device can receive the second configuration information through the first PDSCH carrying the RAR and / or the first DCI carrying the first PDSCH of the RAR.

[0168] In some embodiments, during a first type of random access process, the terminal device receives a second PDSCH and / or a second DCI. The second PDSCH is used to carry message 4 and / or second configuration information, and the second DCI is used to schedule the second PDSCH. The second DCI may or may not include the second configuration information.

[0169] For example, the terminal device receives the second DCI and the second PDSCH scheduled by the second DCI. The second PDSCH is used to carry message 4, wherein the second DCI includes the second configuration information and the second PDSCH does not carry the second configuration information; or, the second DCI does not include the second configuration information and the second PDSCH is used to carry the second configuration information; or, the second DCI includes part of the information in the second configuration information and the second PDSCH is used to carry another part of the information in the second configuration information.

[0170] In some embodiments, the second PDSCH is used to carry message 4 and the second configuration information. This can be implemented as follows: the second PDSCH is used to carry message 4, and message 4 includes the second configuration information; or, the second PDSCH is used to carry the second configuration information, and the second configuration information includes message 4; or, the second PDSCH is used to carry message 4 and the second configuration information respectively.

[0171] In other words, during the first type of random access process, after sending the first PRACH, the terminal device can receive the second configuration information through the second DCI carrying message 4 and / or scheduling the second PDSCH.

[0172] In some embodiments, during the first type of random access process, the behavior of the terminal device includes at least one of the following:

[0173] Receive the first DCI, the first DCI is used to schedule the first PDSCH, the first PDSCH is used to carry response information, and the first DCI includes the second configuration information;

[0174] Receive the first PDSCH, which is used to carry response information and second configuration information;

[0175] Receive the second DCI, the second DCI is used to schedule the second PDSCH, the second PDSCH is used to carry message 4, and the second DCI includes the second configuration information;

[0176] Receive the second PDSCH, which is used to carry message 4 and the second configuration information;

[0177] Receive the fifth PDSCH, which is used to carry the second configuration information;

[0178] Receive the fifth DCI, which includes the second configuration information.

[0179] The response information includes RAR.

[0180] In some embodiments, the fifth DCI may schedule the fifth PDSCH or may not schedule the PDSCH.

[0181] In some embodiments, the fifth PDSCH can be the PDSCH of the fifth DCI scheduling or the SPS (Semi-Persistent Scheduling) PDSCH.

[0182] In other words, during the first type of random access process, after sending the first PRACH, the terminal device can receive the second configuration information through the first PDSCH carrying the RAR and / or the first DCI carrying the first PDSCH of the RAR, or through the second PDSCH carrying message 4 and / or the second DCI carrying the second PDSCH of message 4, or through the fifth PDSCH and / or the fifth DCI after the random access process ends, or through one or more combinations of the above methods. This application does not limit this.

[0183] Using the above method, the terminal device can send a first uplink channel or signal to the first network device via Msg1, and the first network device can decide whether to switch the terminal device to the second network to obtain better communication efficiency. This can avoid or reduce interference in the transmission of communication signals between two networks sharing spectrum resources, thereby improving the effectiveness and reliability of information transmission. At the same time, it can also reduce the resources required for the initial access of terminal devices capable of working in the second network, and improve the utilization rate of communication resources.

[0184] II. The first uplink channel or signal is used to carry MsgA

[0185] In some embodiments, the first uplink channel or signal is an uplink channel or signal in a second type of random access procedure. In some embodiments, in a second type of random access procedure, the first uplink channel or signal includes a first PRACH and / or a first PUSCH. In some embodiments, the second type of random access procedure is a two-step random access procedure.

[0186] In some embodiments, the first configuration information is used to configure a first uplink resource set, which includes one or more first uplink resources. In some embodiments, the first uplink resource set includes a first random access resource set, which includes one or more first uplink resources. For example, the first uplink resources include a first PRACH resource and / or a first PUSCH resource.

[0187] In some embodiments, the first configuration information is used to configure a set of random access resources in the first cell, such as a set of ROs and / or a set of POs. This set of random access resources includes a first random access resource set, such as a first set of ROs and / or a first set of POs, which is used by terminal devices capable of operating in the second network to access the first network. The first uplink resource is a resource in the first random access resource set. In some embodiments, the first random access resource set may be a set of random access resources configured by the first network device specifically for terminal devices capable of operating in the second network to initiate random access, or it may be a set of random access resources configured by the first network device for terminal devices in the first cell to initiate random access.

[0188] In some embodiments, the first configuration information is a first system message. In some embodiments, the first configuration information is first RRC configuration information.

[0189] In some embodiments, the first uplink resource includes PRACH resources and / or PUSCH resources. For example, the first uplink resource includes first PRACH resources and / or first PUSCH resources, and the first uplink channel or signal includes first PRACH and / or first PUSCH, wherein the first PUSCH is used to carry message A (MsgA).

[0190] In some embodiments, the first configuration information is used to configure the first random access resource set in the first cell, including at least one of the following: the first configuration information is used to configure the time domain resources of RO in the first random access resource set, the first configuration information is used to configure the frequency domain resources of RO in the first random access resource set, the first configuration information is used to configure the sequence resources of PRACH in the first random access resource set, the first configuration information is used to configure the time domain resources of PO in the first random access resource set, the first configuration information is used to configure the frequency domain resources of PO in the first random access resource set, and the first configuration information is used to configure the DMRS resources of PO in the first random access resource set.

[0191] In some embodiments, the first configuration information is further used to configure a second uplink resource set, which includes one or more second uplink resources. In some embodiments, the second uplink resource set includes a second random access resource set, which includes one or more second uplink resources. For example, the second uplink resources include a second PRACH resource and / or a second PUSCH resource.

[0192] In some embodiments, the first configuration information is used to configure a second random access resource set in a first cell, which includes a second random access resource set. For example, this may include a second RO set and / or a second PO set. This second random access resource set is used by terminal devices that do not have the capability to operate in a second network to transmit uplink channels or signals.

[0193] In some embodiments, PRACH resources include at least one of the following:

[0194] RO's temporal resources;

[0195] RO's frequency domain resources;

[0196] PRACH sequence resources.

[0197] In some embodiments, the sequence resource of PRACH is the identifier of the PRACH sequence.

[0198] In some embodiments, PUSCH resources include at least one of the following:

[0199] PO's temporal resources;

[0200] PO's frequency domain resources;

[0201] PO's DMRS (Demodulation Reference Signal) resources.

[0202] During the two-step random access process, the first network device can configure first uplink resources and second uplink resources for the terminal device. The first uplink resources are used for terminal devices capable of operating in the second network to send a first uplink channel or signal, and the second uplink resources are used for terminal devices not capable of operating in the second network to send a first uplink channel or signal. Alternatively, the first network device can configure only the first uplink resources for the terminal device. The PUSCH resource within the first uplink resources is used to carry message A, which includes first indication information indicating that the terminal device is capable of operating in the second network.

[0203] In some embodiments, during the two-step random access process, if the first network device detects the first PRACH and receives the first PUSCH, the first network device sends a success RAR to the terminal device; or, if the first network device detects the first PRACH but does not receive the first PUSCH, the first network device sends a fallback RAR to the terminal device.

[0204] (1) The first configuration information is used to determine the first uplink resource and the second uplink resource.

[0205] In some embodiments, the second uplink resource set includes a second random access resource set, which includes one or more second uplink resources. In some embodiments, the second uplink resources are used for terminal devices that do not have the capability to operate in the second network to access the first network.

[0206] In some embodiments, the second uplink resource includes PRACH resources and / or PUSCH resources.

[0207] In some embodiments, the first configuration information is used to configure a first uplink resource set and a second uplink resource set. The first uplink resource set includes one or more first uplink resources, and the second uplink resource set includes one or more second uplink resources. In some embodiments, the first uplink resources are used by terminal devices capable of operating in a second network to transmit uplink channels or signals. In some embodiments, the second uplink resources are used by terminal devices not capable of operating in a second network to transmit uplink channels or signals.

[0208] For example, the first uplink resource set includes a first RO set and / or a first PO set, the first RO set includes a first PRACH resource, and the first PO set includes a first PUSCH resource; the second uplink resource set includes a second RO set and / or a second PO set, the second RO set includes a second PRACH resource, and the second PO set includes a second PUSCH resource.

[0209] In some embodiments, the terminal device sends a first PRACH and / or a first PUSCH to the first network device via the first uplink resource. Correspondingly, the first network device detects the first PRACH and / or the first PUSCH via the first uplink resource. It is understood that only terminal devices capable of operating in the second network can send the first PRACH and / or the first PUSCH to the first network device via the first uplink resource. Therefore, when the first network device receives the first PRACH and / or the first PUSCH via the first uplink resource, it can determine that the terminal device is capable of operating in the second network.

[0210] In some embodiments, the first network device sends second configuration information to the terminal device. Accordingly, the terminal device receives the second configuration information.

[0211] In some embodiments, when the first uplink channel or signal includes a first PRACH and / or a first PUSCH, the response information includes a successful RAR or a fallback RAR. As previously mentioned, when the first network device receives only the first PRACH, the response information includes a fallback RAR. As another example, when the first network device receives both the first PRACH and the first PUSCH, the response information includes a successful RAR.

[0212] (1-1) The first network device successfully sends a RAR to the terminal device.

[0213] In some embodiments, the terminal device sends a first PRACH and a first PUSCH to the first network device via a first uplink resource. Accordingly, the first network device detects the first PRACH and receives the first PUSCH via the first uplink resource.

[0214] In some embodiments, the first network device sends a third PDSCH and / or a third DCI to the terminal device. The third DCI is used to schedule the third PDSCH, and the third PDSCH is used to carry response information. For example, the response information is a successful RAR. Accordingly, the terminal device receives the third PDSCH and / or the third DCI.

[0215] Understandably, in this case, the first network device successfully receives the first PUSCH, so the response information can be the response information corresponding to the first uplink channel or signal (i.e., the first PUSCH).

[0216] For example, the third DCI is the DCI of MsgB-RNTI scrambling, and the third PDSCH carries the successful RAR corresponding to the first PUSCH.

[0217] For example, the third DCI is a DCI with C-RNTI scrambling, and the third PDSCH carries the success RAR corresponding to the first PUSCH. For instance, the first PUSCH sent by the terminal device carries the terminal device's C-RNTI. When the first network device receives the first PUSCH, it can schedule the PDSCH through the DCI with C-RNTI scrambling to respond to the terminal device.

[0218] In some embodiments, the terminal device receives second configuration information sent by the first network device through second downlink resources in the first cell. The second configuration information is used to configure the second network. For example, the terminal device receives a third PDSCH and / or a third DCI through this second downlink resource.

[0219] In some embodiments, during the second type of random access process, the terminal device receives a third PDSCH, which carries response information and / or second configuration information; and / or, the terminal device receives a third DCI, which is used to schedule the third PDSCH, and the third DCI may or may not include the second configuration information. The response information includes a successful RAR.

[0220] For example, the terminal device receives a third DCI and a third PDSCH scheduled by the third DCI. The third PDSCH is used to carry response information. The third DCI includes second configuration information, and the third PDSCH does not carry the second configuration information; or, the third DCI does not include the second configuration information, and the third PDSCH is used to carry the second configuration information; or, the third DCI includes part of the second configuration information, and the third PDSCH is used to carry another part of the second configuration information.

[0221] In some embodiments, the third PDSCH is used to carry response information and second configuration information. This can be implemented such that the third PDSCH carries response information, and the response information includes the second configuration information; or, the third PDSCH carries the second configuration information, and the second configuration information includes the response information; or, the third PDSCH carries both response information and second configuration information respectively.

[0222] In other words, during the second type of random access process, after sending the first PRACH and the first PUSCH, the terminal device can receive the second configuration information through the third DCI carrying the third PDSCH and / or scheduling the third PDSCH.

[0223] In some embodiments, during the second type of random access process, the behavior of the terminal device includes at least one of the following:

[0224] Receive the third DCI, the third DCI is used to schedule the third PDSCH, the third PDSCH is used to carry response information, and the third DCI includes the second configuration information;

[0225] Receive the third PDSCH, which is used to carry response information and second configuration information;

[0226] Receive the fifth PDSCH, which is used to carry the second configuration information;

[0227] Receive the fifth DCI, which includes the second configuration information.

[0228] The response information includes a successful RAR.

[0229] In some embodiments, the fifth DCI may schedule the fifth PDSCH or may not schedule the PDSCH.

[0230] In some embodiments, the fifth PDSCH may be the PDSCH of the fifth DCI scheduler or the SPS PDSCH.

[0231] In other words, during the second type of random access process, after sending the first PRACH and the first PUSCH, the terminal device can receive the second configuration information through the third DCI that carries the successful RAR and / or schedules the third PDSCH, or through the fifth PDSCH and / or the fifth DCI after the random access process ends, or through one or more of the above combinations. This application does not limit this.

[0232] (1-2) The first network device sends a rollback RAR to the terminal device.

[0233] In some embodiments, the terminal device sends a first PRACH and / or a first PUSCH to the first network device via a first uplink resource. Correspondingly, the first network device detects the first PRACH and / or receives the first PUSCH via the first uplink resource.

[0234] In some embodiments, the first network device sends a fourth PDSCH and / or a fourth DCI to the terminal device. The fourth DCI is used to schedule the fourth PDSCH, and the fourth PDSCH is used to carry response information. For example, the response information is a rollback RAR. Accordingly, the terminal device receives the fourth PDSCH and / or the fourth DCI. It is understood that, since different uplink resources are used to distinguish whether the terminal device has the ability to operate in the second network, if the first network device detects the first PRACH through the first uplink resource, even if the first network device does not receive the first PUSCH, it can still determine that the terminal device has the ability to operate in the second network based on the first uplink resource.

[0235] For example, the fourth DCI is the DCI of MsgB-RNTI scrambling, and the fourth PDSCH carries the back-off RAR corresponding to the first PRACH.

[0236] In some embodiments, the terminal device receives second configuration information sent by the first network device through second downlink resources in the first cell. The second configuration information is used to configure the second network. For example, the terminal device receives a fourth PDSCH and / or a fourth DCI through this second downlink resource.

[0237] In some embodiments, during the second type of random access process, the terminal device receives a fourth PDSCH, which carries response information and / or second configuration information; and / or, the terminal device receives a fourth DCI, which is used to schedule the fourth PDSCH and carries response information. The fourth DCI may or may not include the second configuration information. The response information includes a rollback RAR.

[0238] For example, the terminal device receives a fourth DCI and a fourth PDSCH scheduled by the fourth DCI. The fourth PDSCH is used to carry response information. The fourth DCI includes second configuration information, and the fourth PDSCH does not carry the second configuration information; or, the fourth DCI does not include the second configuration information, and the fourth PDSCH is used to carry the second configuration information; or, the fourth DCI includes part of the second configuration information, and the fourth PDSCH is used to carry another part of the second configuration information.

[0239] In some embodiments, the fourth PDSCH is used to carry response information and second configuration information. This can be implemented such that the fourth PDSCH carries response information, and the response information includes the second configuration information; or, the fourth PDSCH carries the second configuration information, and the second configuration information includes the response information; or, the fourth PDSCH carries both response information and second configuration information respectively.

[0240] In other words, during the second type of random access process, after sending the first PRACH and / or the first PUSCH, the terminal device can receive the second configuration information through the fourth DCI carrying the fourth PDSCH and / or scheduling the fourth PDSCH.

[0241] In some embodiments, during the second type of random access process, the terminal device receives a second PDSCH and / or a second DCI. The second PDSCH is used to carry message 4 and / or second configuration information, and the second DCI is used to schedule the second PDSCH. The second DCI may or may not include the second configuration information.

[0242] For example, the terminal device receives the second DCI and the second PDSCH scheduled by the second DCI. The second PDSCH is used to carry message 4, wherein the second DCI includes the second configuration information and the second PDSCH does not carry the second configuration information; or, the second DCI does not include the second configuration information and the second PDSCH is used to carry the second configuration information; or, the second DCI includes part of the information in the second configuration information and the second PDSCH is used to carry another part of the information in the second configuration information.

[0243] In some embodiments, the second PDSCH is used to carry message 4 and the second configuration information. This can be implemented as follows: the second PDSCH is used to carry message 4, and message 4 includes the second configuration information; or, the second PDSCH is used to carry the second configuration information, and the second configuration information includes message 4; or, the second PDSCH is used to carry message 4 and the second configuration information respectively.

[0244] In other words, during the second type of random access process, after sending the first PRACH and / or the first PUSCH, the terminal device can receive the second configuration information through the second DCI carrying message 4 and / or scheduling the second PDSCH.

[0245] In some embodiments, during the second type of random access process, the behavior of the terminal device includes at least one of the following:

[0246] Receive the fourth DCI, the fourth DCI is used to schedule the fourth PDSCH, the fourth PDSCH is used to carry response information, and the fourth DCI includes the second configuration information;

[0247] Receive the fourth PDSCH, which is used to carry response information and second configuration information;

[0248] Receive the second DCI, the second DCI is used to schedule the second PDSCH, the second PDSCH is used to carry message 4, and the second DCI includes the second configuration information;

[0249] Receive the second PDSCH, which is used to carry message 4 and the second configuration information;

[0250] Receive the fifth PDSCH, which is used to carry the second configuration information;

[0251] Receive the fifth DCI, which includes the second configuration information.

[0252] The response information includes rollback to RAR.

[0253] Optionally, the fifth DCI may schedule the fifth PDSCH, or it may not schedule the PDSCH.

[0254] Optionally, the fifth PDSCH can be the PDSCH of the fifth DCI schedule or the semi-persistent schedule SPS PDSCH.

[0255] In other words, during the second type of random access process, after sending the first PRACH and / or the first PUSCH, the terminal device can receive the second configuration information through the fourth DCI carrying the fourth PDSCH and / or scheduling the fourth PDSCH, or through the second PDSCH carrying message 4 and / or scheduling the second DCI carrying message 4, or through the fifth PDSCH and / or the fifth DCI after the random access process ends, or through one or more combinations of the above methods. This application does not limit this.

[0256] (2) The first configuration information is only used to determine the first uplink resource.

[0257] In some embodiments, the terminal device sends a first PRACH and / or a first PUSCH to a first network device. The first PUSCH is used to carry message A, which includes first indication information. The first indication information is used to indicate that the terminal device has the ability to work in a second network.

[0258] In some embodiments, the first configuration information is used to configure a first uplink resource set. The first uplink resource set includes one or more first uplink resources. In some embodiments, regardless of whether the terminal device has the capability to operate in the second network, it can send uplink channels or signals to the first network device through the first uplink resources. Therefore, the first network device cannot determine whether the terminal device has the capability to operate in the second network based on the resources used by the terminal device to send uplink channels or signals; it also needs to use the first indication information to determine this.

[0259] In some embodiments, the first uplink resource includes PRACH resources and / or PUSCH resources. Exemplarily, the first uplink resource includes a first PRACH resource and / or a first PUSCH resource.

[0260] For example, the first uplink resource set includes a first random access resource set, which includes a first RO set and / or a first PO set. The first RO set includes a first PRACH resource, and the first PO set includes a first PUSCH resource.

[0261] In some embodiments, the terminal device sends a first PRACH and / or a first PUSCH to the first network device via a first uplink resource. Correspondingly, the first network device detects the first PRACH and / or the first PUSCH via the first uplink resource. In some embodiments, the first PUSCH carries first indication information, which indicates that the terminal device has the capability to operate in the second network. In some embodiments, if the first network device receives the first PUSCH, the first network device can determine that the terminal device has the capability to operate in the second network, and the first network device sends a successful RAR to the terminal device, the successful RAR carrying second configuration information. In some embodiments, if the first network device does not receive the first PUSCH, the first network device can determine that the terminal device does not have the capability to operate in the second network, and the first network device sends a fallback RAR to the terminal device, the fallback RAR not carrying the second configuration information.

[0262] (2-1) The first network device successfully sends a RAR to the terminal device.

[0263] In some embodiments, the terminal device sends a first PRACH and a first PUSCH to the first network device via a first uplink resource. Accordingly, the first network device detects the first PRACH and receives the first PUSCH via the first uplink resource.

[0264] In some embodiments, the first network device sends a third PDSCH and / or a third DCI to the terminal device. The third DCI is used to schedule the third PDSCH, and the third PDSCH is used to carry response information. For example, the response information is a successful RAR. Accordingly, the terminal device receives the third PDSCH and / or the third DCI.

[0265] In some embodiments, after sending the first PRACH and / or the first PUSCH, the terminal device can receive the second configuration information via a third DCI carrying a third PDSCH with a successful RAR and / or a third PDSCH with a scheduled third PDSCH. For details on this part, please refer to the description in (1-1) above; this application will not repeat it further here.

[0266] (2-2) The first network device sends a rollback RAR to the terminal device.

[0267] In some embodiments, the terminal device sends a first PRACH and / or a first PUSCH to the first network device via a first uplink resource. Correspondingly, the first network device detects the first PRACH and / or receives the first PUSCH via the first uplink resource.

[0268] In some embodiments, the first network device sends a fourth PDSCH and / or a fourth DCI to the terminal device. The fourth DCI is used to schedule the fourth PDSCH, and the fourth PDSCH carries response information. For example, the response information is a rollback RAR. Accordingly, the terminal device receives the fourth PDSCH and / or the fourth DCI. In some embodiments, if the first PUSCH carries first indication information, and the first network device does not receive the first PUSCH, the first network device cannot determine whether the terminal device has the capability to operate in the second network. Therefore, the rollback RAR or the DCI that schedules the rollback RAR does not include the second configuration information.

[0269] In some embodiments, during the second type of random access process, the terminal device receives a fourth DCI, which is used to schedule a fourth PDSCH. The fourth PDSCH is used to carry response information, which includes a rollback RAR. The rollback RAR is used to schedule a second PUSCH, which is used to carry message 3. Message 3 includes first indication information.

[0270] For example, the fourth DCI is the DCI with MsgB-RNTI scrambling, and the fourth PDSCH carries the backoff RAR corresponding to the first PRACH. The uplink grant included in the backoff RAR is used to determine the transmission resources of the second PUSCH.

[0271] In some embodiments, the uplink grant included in the rollback RAR is used to determine a second uplink resource in the first cell, and the message 3 (i.e., the second PUSCH) sent by the terminal device to the first network device through the second uplink resource includes first indication information. The terminal device receives second configuration information sent by the first network device through the second downlink resource in the first cell, including: the terminal device receiving a second PDSCH carrying message 4 through the second downlink resource, the message 4 including the second configuration information; or, the terminal device receiving a second DCI for scheduling the second PDSCH carrying message 4 through the second downlink resource, the second DCI including the second configuration information.

[0272] In some embodiments, the terminal device sends a second PUSCH to the first network device. The second PUSCH carries message 3, which includes first indication information. Accordingly, the first network device receives the second PUSCH.

[0273] For example, the terminal device receives a second PUSCH carrying a rollback RAR and / or a second DCI for scheduling a second PDSCH, and sends message 3 to the first network device through the second PUSCH scheduled by the rollback RAR. Message 3 includes first indication information.

[0274] In some embodiments, after receiving the second PUSCH, the first network device determines that the terminal device is capable of operating in the second network. In some embodiments, after receiving the second PUSCH, the first network device sends a second PDSCH and / or a second DCI. Accordingly, the terminal device receives the second PDSCH and / or the second DCI.

[0275] In some embodiments, the terminal device receives second configuration information sent by the first network device through a second downlink resource in the first cell. The second configuration information is used to configure the second network. For example, the terminal device receives a second PDSCH and / or a second DCI through this second downlink resource.

[0276] In some embodiments, during the second type of random access process, the terminal device receives a second PDSCH, which is used to carry message 4 and second configuration information; and / or, the terminal device receives a second DCI, which is used to schedule the second PDSCH, which is used to carry message 4, and the second DCI may or may not include the second configuration information.

[0277] For example, the terminal device receives the second DCI and the second PDSCH scheduled by the second DCI. The second PDSCH is used to carry message 4, wherein the second DCI includes the second configuration information and the second PDSCH does not carry the second configuration information; or, the second DCI does not include the second configuration information and the second PDSCH is used to carry the second configuration information; or, the second DCI includes part of the information in the second configuration information and the second PDSCH is used to carry another part of the information in the second configuration information.

[0278] In some embodiments, the second PDSCH is used to carry message 4 and the second configuration information. This can be implemented as follows: the second PDSCH is used to carry message 4, which includes the second configuration information; or, the second PDSCH is used to carry the second configuration information, which includes message 4; or, the second PDSCH is used to carry message 4 and the second configuration information respectively.

[0279] In other words, during the second type of random access process, after sending the first PRACH and / or the first PUSCH, the terminal device can receive the second configuration information through the second DCI carrying message 4 and / or scheduling the second PDSCH.

[0280] In some embodiments, during the second type of random access process, the behavior of the terminal device includes at least one of the following:

[0281] Receive the second DCI, the second DCI is used to schedule the second PDSCH, the second PDSCH is used to carry message 4, and the second DCI includes the second configuration information;

[0282] Receive the second PDSCH, which is used to carry message 4 and the second configuration information;

[0283] Receive the fifth PDSCH, which is used to carry the second configuration information;

[0284] Receive the fifth DCI, which includes the second configuration information.

[0285] Optionally, the fifth DCI may schedule the fifth PDSCH, or it may not schedule the PDSCH.

[0286] Optionally, the fifth PDSCH can be the PDSCH scheduled by the fifth DCI or the SPS PDSCH.

[0287] In other words, during the second type of random access process, after sending the first PRACH and / or the first PUSCH, the terminal device can receive the second configuration information through the second PDSCH carrying message 4 and / or the second DCI scheduling the second PDSCH, or it can receive the second configuration information through the fifth PDSCH and / or the fifth DCI after the random access process ends, or it can receive the second configuration information through one or more of the above combinations. This application does not limit this.

[0288] Using the above method, the terminal device can send a first uplink channel or signal to the first network device via MsgA, and the first network device can decide whether to switch the terminal device to the second network to obtain better communication efficiency. This can avoid or reduce interference in the transmission of communication signals between two networks sharing spectrum resources, thereby improving the effectiveness and reliability of information transmission. At the same time, it can also reduce the resources required for initial access of terminal devices capable of working in the second network, thereby improving the utilization rate of communication resources.

[0289] III. The first uplink channel or signal is used to carry Msg3

[0290] In some embodiments, the first uplink channel or signal includes a second PUSCH, which carries message 3 in the random access process. Message 3 includes first indication information, which indicates that the terminal device has the capability to operate in the second network.

[0291] During the four-step random access process, the first network device may configure only one set of random access resources for the terminal device. The PRACH resources in this set can be used by either the first terminal device, which is capable of operating in the second network, to send PRACH messages, or by the second terminal device, which is not capable of operating in the second network. However, after receiving the RAR for the PRACH sent by the first network device, the first terminal device may carry first indication information in the RAR scheduling message 3 to indicate that it has the capability to operate in the second network.

[0292] In some embodiments, the first configuration information is used to determine a first uplink resource in a first cell, wherein the first uplink resource is a second PUSCH resource used for transmitting a second PUSCH.

[0293] For example, the first configuration information is used to indicate the time domain location and frequency domain location of the first uplink resource.

[0294] In some embodiments, the terminal device receives first configuration information sent by the first network device through a first downlink resource in the first cell. For example, the terminal device receives a first PDSCH and / or a first DCI through the first downlink resource. The first PDSCH carries the first configuration information; and / or the first DCI includes the first configuration information.

[0295] In some embodiments, during a first type of random access process, the terminal device receives a first PDSCH and / or a first DCI. The first PDSCH is used to carry response information and / or first configuration information, and the first DCI is used to schedule the first PDSCH. The first DCI may or may not include the first configuration information. The response information includes RAR.

[0296] For example, the terminal device receives a first DCI and a first PDSCH scheduled by the first DCI. The first PDSCH is used to carry response information. The first DCI includes first configuration information, and the first PDSCH does not carry the first configuration information; or, the first DCI does not include the first configuration information, and the first PDSCH is used to carry the first configuration information; or, the first DCI includes part of the information in the first configuration information, and the first PDSCH is used to carry another part of the information in the first configuration information.

[0297] In some embodiments, the first PDSCH is used to carry response information and first configuration information. This can be implemented such that the first PDSCH carries response information, and the response information includes the first configuration information; or, the first PDSCH carries the first configuration information, and the first configuration information includes the response information; or, the first PDSCH carries response information and first configuration information respectively.

[0298] In other words, during the first type of random access process, after sending the first PRACH, the terminal device can receive the first configuration information through the first PDSCH carrying the RAR and / or the first DCI carrying the first PDSCH of the RAR.

[0299] In some embodiments, the first configuration information is carried in the RAR. For example, the first configuration information is an uplink grant (UL grant) carried in the RAR.

[0300] In some embodiments, the first uplink resource is a second PUSCH resource used to transmit the second PUSCH.

[0301] In some embodiments, the terminal device sends a second PUSCH via a second PUSCH resource. The second PUSCH carries message 3, which includes first indication information indicating that the terminal device has the capability to operate in the second network. Accordingly, the first network device receives the second PUSCH.

[0302] In some embodiments, the terminal device receives a second PDSCH and / or a second DCI. The second PDSCH is used to carry message 4 and / or second configuration information, and the second DCI is used to schedule the second PDSCH. The second DCI may or may not include the second configuration information.

[0303] For example, the terminal device receives the second DCI and the second PDSCH scheduled by the second DCI. The second PDSCH is used to carry message 4, wherein the second DCI includes the second configuration information and the second PDSCH does not carry the second configuration information; or, the second DCI does not include the second configuration information and the second PDSCH is used to carry the second configuration information; or, the second DCI includes part of the information in the second configuration information and the second PDSCH is used to carry another part of the information in the second configuration information.

[0304] In some embodiments, the second PDSCH is used to carry message 4 and the second configuration information. This can be implemented as follows: the second PDSCH is used to carry message 4, and message 4 includes the second configuration information; or, the second PDSCH is used to carry the second configuration information, and the second configuration information includes message 4; or, the second PDSCH is used to carry message 4 and the second configuration information respectively.

[0305] In other words, during the first type of random access process, after the terminal device sends the second PUSCH carrying message 3, it can receive the second configuration information through the second PDSCH carrying message 4 and / or the second DCI that schedules the second PDSCH carrying message 4.

[0306] In some embodiments, the behavior of the terminal device includes at least one of the following:

[0307] Receive the second DCI, the second DCI is used to schedule the second PDSCH, the second PDSCH is used to carry message 4, and the second DCI includes the second configuration information;

[0308] Receive the second PDSCH, which is used to carry message 4 and the second configuration information;

[0309] Receive the fifth PDSCH, which is used to carry the second configuration information;

[0310] Receive the fifth DCI, which includes the second configuration information.

[0311] In some embodiments, the fifth DCI may schedule the fifth PDSCH or may not schedule the PDSCH.

[0312] In some embodiments, the fifth PDSCH can be the PDSCH of the fifth DCI scheduling or the SPS (Semi-Persistent Scheduling) PDSCH.

[0313] In other words, during the first type of random access process, after the terminal device sends the second PUSCH carrying message 3, it can receive the second configuration information through the second PDSCH carrying message 4 and / or the second DCI that schedules the second PDSCH carrying message 4, or through the fifth PDSCH and / or the fifth DCI after the random access process ends, or through one or more of the above combinations. This application does not limit this.

[0314] Using the above method, the terminal device can send a first uplink channel or signal to the first network device via Msg3, and the first network device can decide whether to switch the terminal device to the second network to obtain better communication efficiency. This can avoid or reduce interference in the transmission of communication signals between two networks sharing spectrum resources, thereby improving the effectiveness and reliability of information transmission. At the same time, it can also reduce the resources required for the initial access of terminal devices capable of working in the second network, and improve the utilization rate of communication resources.

[0315] IV. The first uplink channel or signal includes PUSCH

[0316] In some embodiments, a terminal device may report its ability to operate in a second network to a first network device via PUSCH.

[0317] In some embodiments, the above-mentioned PUSCH includes DCI-scheduled PUSCH and / or CG-PUSCH.

[0318] In some embodiments, the first configuration information is used to configure a third PUSCH resource set, which includes one or more third PUSCH resources. For example, the first configuration information is CG-PUSCH configuration information, and the third PUSCH resource set includes multiple CG-PUSCH resources configured by the first configuration information.

[0319] In some embodiments, the terminal device sends a third PUSCH through a third PUSCH resource in a third PUSCH resource set. The third PUSCH carries first indication information, which indicates that the terminal device has the capability to operate in the second network. Accordingly, the first network device receives the third PUSCH.

[0320] In some embodiments, the first uplink resource is the fourth PUSCH resource, which is determined based on the first configuration information and the DCI carrying the uplink grant. In some embodiments, the DCI information is used to schedule the fourth PUSCH. Exemplarily, the first configuration information is used to configure one or more candidate time-domain resources in a candidate time-domain resource set for PUSCH transmission, and the DCI information is used to indicate which one or more candidate time-domain resources in the candidate time-domain resource set are the fourth PUSCH resources.

[0321] In some embodiments, the terminal device sends a fourth PUSCH via a fourth PUSCH resource. The fourth PUSCH carries first indication information, which indicates that the terminal device has the capability to operate in the second network. Correspondingly, the first network device receives the fourth PUSCH via the fourth PUSCH resource.

[0322] In some embodiments, the terminal device receives second configuration information from a first network device, the second configuration information being used to configure a second network. Accordingly, the first network device sends the second configuration information.

[0323] In some embodiments, the terminal device receives second configuration information sent by the first network device through second downlink resources in the first cell. In some embodiments, the terminal device receives a fifth PDSCH and / or a fifth DCI, wherein the fifth PDSCH is used to carry the second configuration information, and / or the fifth DCI includes the second configuration information.

[0324] In some embodiments, the terminal device receives a fifth PDSCH and / or a fifth DCI through the second downlink resource, wherein the fifth PDSCH is used to carry second configuration information, and / or the fifth DCI includes the second configuration information.

[0325] For example, the terminal device receives a fifth DCI and a fifth PDSCH scheduled by the fifth DCI, wherein the fifth DCI includes second configuration information and the fifth PDSCH does not carry the second configuration information; or, the fifth DCI does not include the second configuration information and the fifth PDSCH is used to carry the second configuration information; or, the fifth DCI includes part of the information in the second configuration information and the fifth PDSCH is used to carry another part of the information in the second configuration information.

[0326] In some embodiments, the fifth DCI may schedule the fifth PDSCH or may not schedule the PDSCH.

[0327] In some embodiments, the fifth PDSCH can be the PDSCH of the fifth DCI scheduling or the SPS (Semi-Persistent Scheduling) PDSCH.

[0328] In other words, terminal devices in the first network that are in a connected or inactive state can receive the second configuration information through the fifth PDSCH and / or the fifth DCI.

[0329] Using the above method, the terminal device can send a first uplink channel or signal to the first network device via PUSCH, and the first network device can decide whether to switch the terminal device to the second network to obtain better communication efficiency. This can avoid or reduce interference in the transmission of communication signals between two networks sharing spectrum resources, thereby improving the effectiveness and reliability of information transmission. At the same time, it can also reduce the resources required for initial access of terminal devices capable of working in the second network, thereby improving the utilization rate of communication resources.

[0330] In some embodiments, the second configuration information mentioned in the above embodiments can be determined based on PDSCH, DCI, or both. It should be noted that if the PDSCH carries all the information of the second configuration information, then the DCI used to schedule the PDSCH may not include the second configuration information; conversely, if the DCI used to schedule the PDSCH includes all the information of the second configuration information, then the PDSCH may not carry the second configuration information. In some embodiments, the PDSCH can be any one of the first PDSCH, the second PDSCH, and the third PDSCH, and the DCI is the DCI used to schedule the PDSCH.

[0331] When the PDSCH is the fourth PDSCH, it is also necessary to consider whether the first network device can determine whether the terminal device has the ability to work in the second network through the first uplink resources used by the terminal device. If the first network device can determine whether the terminal device has the ability to work in the second network through the first uplink resources used by the terminal device, then the fourth PDSCH and the fourth DCI used to schedule the fourth PDSCH are also subject to the above description.

[0332] In some embodiments, the response information mentioned in the above embodiments may also include the identification information of the terminal device.

[0333] In some embodiments, the response information includes at least one of the following: a first RNTI, which is the RNTI of the terminal device in the first network; a second RNTI, which is the RNTI of the terminal device in the second network; and a sequence identifier of the first PRACH.

[0334] In some embodiments, the response information includes an RNTI. The PDSCH and / or DCI also include second indication information, which indicates whether the RNTI is a first RNTI or a second RNTI.

[0335] In some embodiments, the response information can be any one of RAR, successful RAR, and rollback RAR; PDSCH can be any one of first PDSCH, third PDSCH, and fourth PDSCH; and DCI can be any one of first DCI, third DCI, and fourth DCI.

[0336] For example, the response information is a RAR, which includes a first RNTI and a second RNTI. Alternatively, the RAR includes an RNTI, and the RAR, or the PDSCH used to carry the RAR, or the DCI used to schedule the PDSCH carrying the RAR includes second indication information, which indicates whether the RNTI is the first RNTI or the second RNTI. The PDSCH can be the first PDSCH, and the DCI can be the first DCI.

[0337] For example, the response information is a successful RAR, which includes a first RNTI and a second RNTI. Alternatively, a successful RAR may include one RNTI, and the successful RAR may also include a second indication information in the PDSCH used to carry the successful RAR, or in the DCI used to schedule the PDSCH carrying the successful RAR. This second indication information indicates whether the RNTI is the first or the second RNTI. The PDSCH may be a third PDSCH, and the DCI may be a third DCI.

[0338] For example, the response information is a rollback RAR, which includes a first RNTI and a second RNTI. Alternatively, the rollback RAR includes one RNTI while the RAR is rolled back, or the PDSCH used to carry the rollback RAR, or the DCI used to schedule the PDSCH carrying the rollback RAR, includes second indication information, which indicates whether the RNTI is the first RNTI or the second RNTI. The PDSCH can be a fourth PDSCH, and the DCI can be a fourth DCI.

[0339] In some embodiments, after receiving the second configuration information, the terminal device may also perform at least one of the following actions:

[0340] Access the second cell in the second network according to the second configuration information;

[0341] Mobility management is performed on cells in the second network based on the second configuration information;

[0342] Listen for paging messages in the second network according to the second configuration information;

[0343] Switch to the second network based on the second configuration information.

[0344] In some embodiments, after receiving the second configuration information, the terminal device can access the second network according to the second configuration information. In some embodiments, after receiving the second configuration information, the terminal device can perform mobility management on cells in the second network according to the second configuration information. In some embodiments, if the terminal device does not receive the second configuration information, then the terminal device can access the first network.

[0345] In some embodiments, after receiving the second configuration information, the terminal device sends an ACK message to the first network device. Correspondingly, the first network device sends an ACK message.

[0346] In some embodiments, the first network may be a 5G network and the second network may be a 6G network, or the first network may be a 6G network and the second network may be a 5G network. In some embodiments, the first network may be a TN network and the second network may be an NTN network, or the first network may be an NTN network and the second network may be a TN network. Please refer to Figure 10. The following will exemplify the wireless communication method provided in the embodiments of this application, taking a 5G network as the first network and a 6G network as the second network.

[0347] The base station (first network device) serves as both a base station in the 5G network and a base station in the 6G network. The base station transmits SSB and SIB1 in the 5G network through the first downlink spectrum resources, and configures RO resources for the 5G network through SIB1.

[0348] In some embodiments, the RO resources include a first RO set (a first random access resource set) and a second RO set (a second random access resource set). The first RO set is used by UEs with 6G terminal capabilities to initiate random access procedures, and the second RO set is used by UEs without 6G terminal capabilities to initiate random access procedures. A 6G UE (terminal device) can send a first PRACH to the base station through the PRACH resources in the first RO set. When the base station detects the first PRACH, it can determine that the UE has 6G network operational capabilities by transmitting the corresponding first RO set through the first PRACH. Accordingly, the base station can send second configuration information to the UE through a RAR message, message 4, or subsequent scheduling. The second configuration information may include a 6G SIB or handover information for a 6G cell configured for the UE. When the UE receives the second configuration information, it can consider that it has accessed the 6G network. Alternatively, the base station may not send the second configuration information to the UE, in which case the UE can consider that it has accessed the 5G network.

[0349] In some embodiments, UEs with 6G terminal capabilities and UEs without 6G terminal capabilities correspond to the same RO set, meaning that terminal devices with different capabilities cannot be distinguished by the RO set. However, during the four-step random access process, a UE with 6G terminal capabilities can carry its 6G terminal capability information in message 3 after receiving the RAR response from the network device. After receiving message 3, the base station can send second configuration information to the UE in message 4 or in subsequent scheduling. Alternatively, during the two-step random access process, a UE with 6G terminal capabilities can carry its 6G terminal capability information in the PUSCH carrying message A. After receiving message A, the base station can send second configuration information to the UE in message B or in subsequent scheduling. When the UE receives the second configuration information, it can consider that it has accessed the 6G network. Alternatively, the base station may not send the second configuration information to the UE, in which case the UE can consider that it has accessed the 5G network.
