For example, "A and / or B" can mean: only A, only B, and A and B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0038] The method provided in the embodiments of the present disclosure can be applicable to scenarios where multiple communication systems coexist. The communication system can be a fifth-generation (5G) communication system, a wireless local area network (WLAN) system, a third-generation partnership project (3GPP)-related communication system, a future-evolved communication system (such as a sixth-generation (6G) communication system), or a system that integrates multiple systems, and the embodiments of the present disclosure are not limited to this.

[0039] The method provided by the embodiments of the present disclosure is applicable to network-side devices and terminal-side devices in a new generation communication system in which multiple communication systems coexist. For ease of description, the new generation communication system is referred to as the first communication system, and the old generation communication system is referred to as the second communication system.

[0040] As an example, the first communication system in the embodiment of the present disclosure is a 6G communication system, and the second communication system is a 5G communication system.

[0041] In the embodiments of the present disclosure, the network architecture of a communication network (including but not limited to third generation (3G), 4G, 5G, and future mobile communication networks) may include at least a first node and a second node. In this example, the first node may be a terminal-side device (e.g., including but not limited to a terminal), and the second node may be a network-side device (e.g., including but not limited to a base station).

[0042] For example, taking the first node as a terminal and the second node as a base station, as shown in FIG1 , a schematic diagram of a first communication system provided by an embodiment of the present disclosure is shown. The first communication system includes a terminal 110 and a base station 120. The terminal 110 is in communication with the base station 120.

[0043] In some embodiments, there may be one or more base stations 120 and one or more terminals 110, and the embodiments of the present disclosure do not limit the number.

[0044] In some embodiments, the base station 120 may provide network services of different standards for the terminal 110. For example, the base station 120 may provide the terminal 110 with long term evolution (LTE) network services, new radio (NR) network services, and the like.

[0045] The terminal 110 is configured to determine a first transmission resource based on a signaling instruction from the base station 120, and communicate with the base station 120 based on the first transmission resource. The first transmission resource and a second transmission resource of the second communication system share a shared spectrum.

[0046] In some embodiments, the first transmission resource and the second transmission resource share the shared spectrum in a time division manner; or, the first transmission resource and the second transmission resource share the shared spectrum in a frequency division manner.

[0047] In some embodiments, the terminal 110 can also determine the time slots / symbols occupied by the first transmission resource, the time slots / symbols that the first transmission resource needs to avoid, the frequency domain allocation ratio of the first transmission resource and the second transmission resource on the shared spectrum, etc. based on the signaling instructions of the base station 120.

[0048] In some embodiments, the terminal 110 may also reuse the cell configuration of the second communication system based on the signaling instruction of the base station 120; or, add the cell configuration of the first communication system on the basis of the cell configuration of the second communication system; or, use an independent cell configuration.

[0049] Exemplarily, the terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal may sometimes also be referred to as a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent or UE device, etc., and the embodiments of the present disclosure do not limit this.

[0050] The base station 120 may dynamically allocate spectrum resources (ie, first transmission resources) to the terminal 110 and communicate with the terminal 110 based on the first transmission resources.

[0051] In some embodiments, the base station 120 can send a signaling indication to the terminal to instruct the terminal 110 to determine the time slots / symbols occupied by the first transmission resource, the time slots / symbols that the first transmission resource needs to avoid, the frequency domain allocation ratio of the first transmission resource and the second transmission resource on the shared spectrum, etc.

[0052] In some embodiments, the base station 120 may also send an indication regarding the cell configuration to the terminal 110, so that the terminal 110 reuses the cell configuration of the second communication system based on the signaling indication; or, adds the cell configuration of the first communication system on the basis of the cell configuration of the second communication system; or, uses an independent cell configuration.

[0053] Exemplarily, the base station can be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station device in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, wireless remote stations, reconfigurable intelligent surfaces (RISs), routers, relays, wireless fidelity (WIFI) devices and other network side devices.

[0054] It should be noted that the above scenarios are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Ordinary technicians in this field can know that with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0055] In communication systems, driven by the ever-increasing demand for data transmission and the need for higher transmission rates, lower transmission latency, and more reliable connections, communication technologies are developing rapidly and are poised for widespread adoption. As the next generation of mobile communication technology, 6G communication technology is expected to provide even higher data rates, lower transmission latency, and wider coverage. Because 6G communication systems require wider spectrum bandwidths and higher transmission rates, they also place greater demands on spectrum resources. However, with the development of communication systems and the growing demand for wireless communications, spectrum resources are becoming increasingly scarce worldwide, potentially posing challenges to the deployment and development of 6G communication systems.

[0056] Traditional technologies such as multi-system compatibility and dynamic spectrum sharing have played a crucial role in the smooth evolution of 4G to 5G communication systems, ensuring their deployment and development. Similarly, 6G communication systems will coexist with other communication systems for a long time to come, sharing their spectrum resources. Therefore, ensuring compatibility between 5G and 6G communication systems and ensuring that 6G can smoothly share spectrum resources with other systems is crucial to ensuring the deployment and development of 6G communication systems and achieving a smooth evolution from 5G to 6G.

[0057] To address the above issues, see Figure 2, which is a flow chart of a wireless communication method provided by an embodiment of the present disclosure. As shown in Figure 2, the wireless communication method provided by an embodiment of the present disclosure is applied to a first node, including the following steps:

[0058] S101: Determine a first transmission resource of a first communication system.

[0059] The first transmission resource and the second transmission resource of the second communication system share a shared spectrum.

[0060] In some embodiments, the first transmission resource is used for communication between a first node (eg, a terminal) and a second node (eg, a base station) in a first communication system, and the second transmission resource is used for communication between communication nodes in a second communication system.

[0061] In some embodiments, the first transmission resource and the second transmission resource do not overlap.

[0062] As an example, the first transmission resource and the second transmission resource share the shared spectrum in a time-division manner. For example, as shown in FIG3 , which is a schematic diagram of a shared spectrum, the first transmission resource and the second transmission resource are time-divisioned on the shared spectrum. During the period t1-t2, the first transmission resource uses all of the spectrum.

[0063] As another example, the first transmission resource and the second transmission resource share a shared spectrum in a frequency division manner. For example, in the shared spectrum shown in FIG4 , during the period t1-t2, the first transmission resource and the second transmission resource occupy different frequency domains on the shared spectrum. In addition, as shown in FIG4 , in addition to the shared spectrum, the first communication system may also occupy other frequency domain resources on the spectrum (that is, if the first communication system is in frequency division duplex (FDD) mode, the first communication system may occupy a frequency band at a frequency band position other than the frequency band occupied by the shared spectrum).

[0064] In some embodiments, the first communication system may use multiple frequency bands, and the multiple frequency bands include the frequency band where the above-mentioned shared spectrum is located.

[0065] In some embodiments, if the second communication system uses a time division duplex (TDD) mode, for example, the second communication system uses the N78 frequency band (or the N79 frequency band), then the uplink and downlink transmissions in the second communication system share the N78 frequency band in a time-division manner within the spectrum resources. In this case, the first communication system also uses the TDD mode, that is, the uplink and downlink transmissions in the first communication system share the N78 frequency band.

[0066] In some embodiments, if the second communication system adopts the FDD mode, then in the second communication system, uplink transmission and downlink transmission use different frequency bands. For example, in the second communication system, the frequency band used for uplink transmission is the 700MHz frequency band, and the frequency band used for downlink transmission is the 800MHz frequency band. In this case, the first communication system also adopts the FDD mode, that is, in the first communication system, uplink transmission and downlink transmission use different frequency bands. The frequency band used for uplink transmission of the first communication system is the same as the frequency band used for uplink transmission of the second communication system; or, the frequency band used for downlink transmission of the first communication system is the same as the frequency band used for downlink transmission of the second communication system.

[0067] It is understandable that if the first communication system uses a different operating mode from the second communication system (for example, the first communication system uses the TDD mode and the second communication system uses the FDD mode), this may result in waste of frequency band resources or frequency interference. Therefore, in order to maximize the utilization of frequency band resources and avoid spectrum conflicts, the first communication system and the second communication system in the embodiment of the present disclosure use the same operating mode to ensure that the two systems can coordinate and coexist on the shared spectrum and effectively utilize the resources of the shared spectrum, thereby reducing unnecessary interference.

[0068] S102: Communicate with a second node in the first communication system based on the first transmission resource.

[0069] In some embodiments, after determining the first transmission resource, the first node may establish a connection with the second node and communicate based on the location of the first transmission resource on the shared spectrum.

[0070] It should be noted that when the first node and the second node communicate, data transmission can be unidirectional or bidirectional, which is not limited in the embodiments of the present disclosure.

[0071] Based on the wireless communication method provided in the embodiment of the present disclosure, the first transmission resource shares a shared spectrum with the second transmission resource of the second communication system, so that the first communication system (e.g., a 6G communication system) can obtain more spectrum resources to meet the first communication system's demand for spectrum resources. In addition, based on the first transmission resource and the second transmission resource sharing a shared spectrum, the first node communicates with the second node in the first communication system based on the first transmission resource, thereby avoiding conflicts between the first communication system and the second communication system, and ensuring the smooth deployment and sustainable development of the first communication system during the transition period of coexistence of the first communication system and the second communication system.

[0072] Not only that, the first transmission resource can effectively utilize the idle or available resources in the shared spectrum by sharing the shared spectrum with the second transmission resource of the second communication system, improve the utilization efficiency of the shared spectrum, maximize the utilization of the shared spectrum resources, and avoid waste of resources.

[0073] In some embodiments, the first transmission resource and the second transmission resource share a shared spectrum in a time-division manner, and the above method further includes: receiving a first signaling.

[0074] The first signaling is used to indicate the time slot occupied by the first transmission resource.

[0075] In some embodiments, the time slots occupied by the first transmission resource include at least one of the following: a first type time slot and a second type time slot. All symbols in the first type time slot are used to transmit signals of the first communication system. For example, as shown in FIG5 , the time slots occupied by the shaded portions of the first type time slots in the figure are first type time slots, in which all symbols are used to transmit signals of the first communication system. Furthermore, no signals or channels of the second communication system are transmitted in these time slots.

[0076] Some symbols in the second type of time slot are used to transmit signals of the first communication system, and another part of the symbols are used to transmit signals of other communication systems. For example, as shown in Figure 6, in the second type of time slot, the shaded symbols are used to transmit signals of the first communication system, and the other symbols except the shaded symbols are used to transmit signals of other communication systems.

[0077] It can be understood that, considering that there may be symbols occupied by the second communication system in the shared spectrum, in the method provided in the embodiment of the present disclosure, the first communication system only occupies part of the symbols on the second type of time slot, which can avoid interference with the second transmission resources in the second communication system.

[0078] In some embodiments, the second type time slot satisfies at least one of the following:

[0079] a. The second type of time slot includes symbols for transmitting common signals of the second communication system. For example, the common signals may be synchronization signal blocks (SSBs) or repetition and spreading (RS) signals.

[0080] b. The second type of time slot includes symbols used to transmit a control channel of the second communication system. Exemplarily, the second type of time slot includes symbols used to transmit a physical downlink control channel (PDCCH) of the second communication system.

[0081] c. The second type of time slot includes symbols used to transmit a demodulation reference signal (DMRS) of the second communication system.

[0082] d. The second type of time slot includes symbols used to transmit a shared channel of the first communication system. Exemplarily, the shared channel of the first communication system includes a physical downlink shared channel (PDSCH) of the first communication system and a physical uplink shared channel (PUSCH) of the first communication system.

[0083] In some embodiments, if the first node supports a first communication system and a second communication system, and the first communication system and the second communication system can be time-division multiplexed at the symbol level, the shared channel of the first communication system may occupy certain symbols, such as symbols 4-14 within a second type of time slot. In other words, in the second type of time slot, the shared channel of the first communication system will transmit data on these symbols. The configuration parameters of the second type of time slot are configured based on the subcarrier spacing and frame structure of the second communication system.

[0084] It can be understood that the reason why the shared channel of the first communication system only occupies some specific symbols and does not occupy other symbols in the second type of time slot is to avoid data transmission on the symbols already occupied by the second transmission resource and the symbols occupied by the cell-specific reference signals (CRS), and to avoid mutual interference and conflict between the first transmission resource and the second transmission resource.

[0085] e. The second type time slot does not include symbols used to transmit a shared channel of the second communication system. Exemplarily, the shared channel of the second communication system includes a PDSCH channel of the second communication system and a PUSCH channel of the second communication system.

[0086] f. The second type time slot includes a symbol for transmitting a common reference symbol (CRS) of a third communication system. Exemplarily, the third communication system may be a long term evolution (LTE) system in a 4G network.

[0087] g. The second type of time slot does not include symbols used to transmit a control channel of the second communication system. Exemplarily, the second type of time slot does not include symbols used to transmit a physical uplink control channel (PUCCH) of the second communication system.

[0088] h. The second type of time slot does not include a random access channel occasion (RO) of the second communication system.

[0089] In some embodiments, when the time slots occupied by the first transmission resource include second-type time slots, the first signaling is further used to indicate symbols in the second-type time slots used to transmit signals of the first communication system. Exemplarily, the first signaling indicates that the symbols in the second-type time slots used to transmit signals of the first communication system are symbols 4-14.

[0090] In some embodiments, the first signaling is carried in broadcast information of the second communication system; or, the first signaling is carried in control signaling of the first communication system.

[0091] As an example, the second node carries the first signaling in broadcast information of the second communication system. The broadcast information may indicate whether the first transmission resource of the first communication system occupies a time slot in the shared spectrum. Furthermore, the second node may also indicate the type of the time slot occupied by the first transmission resource through the broadcast information of the second communication system, for example, indicating whether the time slot occupied by the first transmission resource is a first type time slot and / or a second type time slot.

[0092] In some embodiments, if the first signaling is carried in the broadcast information of the second communication system, except for the time slot or subframe where the broadcast information is located, the signals / channels of the second communication system (including uplink signals, downlink signals, uplink channels and downlink channels) are not transmitted in other time slots or subframes occupied by the second communication system.

[0093] As another example, the second node carries the first signaling in control signaling of the first communication system (e.g., a media access control (MAC) control element (CE)). The control signaling may indicate the type of the time slot occupied by the first transmission resource, for example, indicating that the time slot occupied by the first transmission resource is a first type time slot and / or a second type time slot. Furthermore, the second node may also indicate, through control signaling, the symbol occupied by the first transmission resource in a certain first type time slot.

[0094] As another example, the second node may also indicate the time slot and time slot type occupied by the first transmission resource in the PDCCH of the first communication system. Further, the second node may also indicate the symbol occupied by the first transmission resource in a first type time slot through the PDCCH of the first communication system.

[0095] It can be understood that in the method provided by the embodiment of the present disclosure, the first signaling is carried in the broadcast information of the second communication system or in the control signaling of the first communication system, and additional information can be carried in the existing broadcast information or control signaling, thereby reducing the demand for additional spectrum resources, avoiding the waste of resources caused by opening new channels for a small amount of signaling data, and reducing the operating costs of the communication system.

[0096] In some embodiments, the first transmission resource and the second transmission resource share a shared spectrum in a frequency division manner, and the above method further includes: receiving a second signaling.

[0097] The second signaling is used to indicate a frequency domain allocation ratio between the first transmission resource and the second transmission resource on the shared spectrum.

[0098] For example, if there is a total of 100 MHz of frequency domain resources, and the second signaling indicates that the first transmission resource and the second transmission resource are in a time slot of the shared spectrum, with a frequency domain allocation ratio of 1:1, then the first transmission resource occupies half of the 100 MHz frequency domain resource in the time slot, and the second transmission resource occupies the other half of the 100 MHz frequency domain resource in the time slot. In addition, the first communication system may also use other spectrum resources in addition to the shared spectrum. For example, the TDD subband of the first communication system uses 200 MHz frequency domain resources in some time slots.

[0099] In some embodiments, the shared spectrum serves as a secondary carrier of the first communication system, and the second signaling is carried in the signaling of the primary carrier of the first communication system; or, the shared spectrum serves as the primary carrier of the first communication system, and the second signaling is carried in the broadcast information of the second communication system.

[0100] As an example, if the shared spectrum serves as a secondary carrier of the first communication system, the second signaling is carried in the signaling of the primary carrier of the first communication system (e.g., downlink control information (DCI)). The second node may indicate, based on the DCI, a frequency domain allocation ratio of the first transmission resource and the second transmission resource on the shared spectrum; or, based on the DCI, the second node may indicate the allocation of frequency domain resources for the first transmission resource and the second transmission resource in ascending order of the physical resource block (PRB) number.

[0101] As another example, the second node can indicate the frequency domain allocation ratio of the first transmission resource and the second transmission resource on the shared spectrum based on a new MAC CE (i.e., different from the MAC CE of the second communication system); or, the second node can also indicate, based on the MAC CE, the allocation of frequency domain resources to the first transmission resource and the second transmission resource in order of PRB numbers from low to high.

[0102] In some embodiments, the second node sends the second signaling to the first node at a time granularity of 1 ms or 1 time slot.

[0103] It is understood that in the methods provided by the embodiments of the present disclosure, using shared spectrum as a secondary carrier for the first communication system can increase additional spectrum resources without affecting the normal communication services of the primary carrier, thereby improving the overall communication capacity of the first communication system. Carrying the secondary signaling within the signaling of the primary carrier can ensure the priority transmission and processing of critical control information, while simultaneously transmitting additional data streams through the secondary carrier, achieving more efficient data management and distribution.

[0104] On the contrary, if the shared spectrum is used as the main carrier and the second signaling is carried in the broadcast information of the second communication system, the first communication system and the second communication system can share signaling information, reduce the redundancy of signaling transmission and achieve better integration and coordination between different communication systems.

[0105] In some embodiments, on the shared spectrum, the cell configuration of the first communication system is the same as the cell configuration of the second communication system. That is, on the shared spectrum, it is assumed that the cell configuration of the first communication system is the same as the cell configuration of the second communication system.

[0106] In some embodiments, the above method further includes: receiving third signaling.

[0107] The third signaling is used to instruct the cell configuration of the first communication system to reuse the cell configuration of the second communication system.

[0108] In some embodiments, the shared spectrum serves as a secondary carrier of the first communication system, and the third signaling is carried in the signaling of the primary carrier of the first communication system; alternatively, the shared spectrum serves as the primary carrier of the first communication system, and the third signaling is carried in the broadcast information of the second communication system. For example, if the shared spectrum serves as a secondary carrier of the first communication system, the third signaling can be carried in the radio resource control (RRC) signaling of the primary carrier of the first communication system.

[0109] In some embodiments, the third signaling includes a bit, and the first node determines whether the cell configuration of the first communication system reuses the cell configuration of the second communication system based on the value of the bit. Exemplarily, a value of 1 indicates that the cell configuration of the first communication system reuses the cell configuration of the second communication system, and a value of 0 indicates that the cell configuration of the first communication system does not reuse the cell configuration of the second communication system.

[0110] Exemplarily, if the value of the bit in the third signaling is 1, the first node determines that the cell configuration of the first communication system reuses the cell configuration of the second communication system (for example, TDD uplink (UL)-downlink (DL) configuration, subcarrier spacing configuration, etc.). As an example, the TDD UL-DL configuration of the first communication system is the same as the TDD UL-DL configuration of the second communication system, and the time slot occupied by the first transmission resource starts from the starting point of the configuration period of the TDD UL-DL. For example, the time slot occupied by the first transmission resource is allocated to the first transmission resource at the starting point of the TDD UL-DL configuration period of 2.5 milliseconds or 5 milliseconds. Exemplarily, as shown in Figure 7, the configuration period of the TDD UL-DL of the second transmission resource in the second communication system is DDDUU, then the time slot occupied by the first transmission resource starts from the starting point of a period, and the order of the symbols in the time slot is also DDDUU. As another example, the TDD UL-DL configuration of the first communication system and the TDD UL-DL configuration of the second communication system may also be different, that is, the time slot occupied by the first transmission resource can start from any time slot. In addition, as shown in Figure 7, in addition to the shared spectrum, the first communication system can also occupy other frequency domain resources on the spectrum (that is, if the first communication system is FDD, the first communication system can occupy a frequency band at a frequency band position other than the frequency band occupied by the shared spectrum).

[0111] In some embodiments, on a shared spectrum, the cell configuration of the first communication system is independent of the cell configuration of the second communication system.

[0112] Exemplarily, if the first transmission resource and the second transmission resource are time-divided on the shared spectrum, or the time slot occupied by the first transmission resource is a first type time slot (the first transmission resource uses the entire spectrum resource in the first type time slot), the first communication system can use an independent cell configuration (e.g., an SSB configuration, an RS configuration). For example, if the shared spectrum serves as a secondary carrier of the first communication system, the second node instructs the first communication system to use an independent cell configuration through signaling of the primary carrier of the first communication system.

[0113] Regarding the SSB configuration, in some embodiments, on a shared spectrum, the synchronization signal block SSB configuration of the first communication system is independent of the SSB configuration of the second communication system.

[0114] In some embodiments, as shown in FIG8 , the time-frequency resource position occupied by the synchronization signal block SSB of the first communication system is different from the time-frequency resource position occupied by the SSB of the second communication system.

[0115] In some embodiments, in addition to being the same as the cell configuration of the second communication system, reusing the cell configuration of the second communication system, or being independent of the cell configuration of the second communication system, the cell configuration of the first communication system may also add a new cell configuration based on the cell configuration of the second communication system. For example, a new SSB (e.g., a new structure SSB) is configured based on the SSB of the second communication system. Exemplarily, the time-frequency resource positions occupied by the new structure SSB are different from the time-frequency resource positions occupied by the SSB of the second communication system. At this time, the first communication system can use the SSB of the second communication system and the SSB of the new structure to transmit data.

[0116] In some embodiments, if the first communication system and the second communication system use the same SSB, for example, SSB index 1, the first communication system and the second communication system should send the same maximum burst interval (MBI) information on the SSB, and the first signaling mentioned in the above-mentioned disclosed embodiment can be carried in the broadcast message in the SSB.

[0117] In some embodiments, an SSB includes at least one of the following: a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH). For example, taking an SSB with a period of 20 ms as an example, the transmission mode of the SSB at each symbol position is as follows: the first symbol is empty, the second to fifth symbols contain the PSS and SSS, the sixth to seventh symbols are empty, and the eighth to eleventh symbols contain the PBCH.

[0118] In some embodiments, for example, if each SSB includes only two symbols, there are 2 symbols between every two SSBs.

[0119] In some embodiments, on a shared spectrum, the first node receives an SSB beam at the time domain position of the SSB of the second communication system, and may also receive an SSB beam at the time domain position of the SSB of the first communication system.

[0120] It can be understood that in the method provided by the embodiment of the present disclosure, on the shared spectrum, the first node can configure a specific SSB index to receive the SSB beam at a specified position, that is, the first node can choose to receive the beam at a specific SSB index position, and the beam may include legacy SSB (old SSB) and other possible new SSB beams. In this way, the first node can communicate based on the first communication system or the second communication system, which helps to provide better compatibility.

[0121] Furthermore, during downlink beam scanning, the SSB index includes both the SSB index of the first communication system and the SSB index of the second communication system. The first node can find the optimal receiving beam by scanning the entire SSB index range. Similarly, a similar approach can be adopted during uplink beam scanning.

[0122] For RS configuration, the first and second communication systems can adopt different configuration methods to share and manage RS. For example, in TDD mode, the first and second communication systems can use the same RS configuration; in FDD (frequency division duplex) mode, RS resources can be allocated to the first and second communication systems based on different frequency bands and bandwidth configurations. For example, for the first communication system, RS resources can be configured to suit the bandwidth of the first communication system; for the second communication system, RS resources can be configured to suit the bandwidth of the first communication system.

[0123] It is understandable that the first communication system and the second communication system can flexibly configure RS resources as needed to achieve collaborative work between different systems and ensure normal communication of devices in different environments, thereby improving system efficiency and performance and promoting a smooth transition between different communication systems.

[0124] In some embodiments, the method further includes: receiving fourth signaling, wherein the fourth signaling is used to indicate the third transmission resource.

[0125] In some embodiments, the third transmission resource does not support communication between the first node and the second node, that is, the first node cannot communicate with the second node using the third transmission resource.

[0126] In some embodiments, the third transmission resource includes at least one of the following: a time slot that does not support communication between the first node and the second node, or a symbol that does not support communication between the first node and the second node. For example, the third transmission resource may be a time slot or symbol that is already occupied by the second transmission resource.

[0127] In some embodiments, the method further includes receiving fifth signaling. The fifth signaling is used to indicate at least one of the following: time slots to be avoided by the first transmission resource, and symbols to be avoided by the first transmission resource. For example, the fifth signaling may indicate that the first transmission resource avoids time slots, channels, or symbols occupied by the second transmission resource within one or more time slots. Alternatively, the fifth signaling may indicate that the first transmission resource avoids time slots, channels, or symbols occupied by the second transmission resource within one or more cycles.

[0128] In some embodiments, the second node may further send a signaling instruction to the first node, instructing the first node's first transmission resource to avoid some RBs. For example, the first transmission resource may be instructed to avoid 20 RBs and four consecutive symbols occupied by SSB. For example, as shown in FIG9 , the first transmission resource may avoid RBs occupied by SSB in the frequency domain; in the time domain, the first transmission resource may avoid four consecutive symbols among the symbols occupied by SSB.

[0129] In some embodiments, if the shared spectrum is configured with the signal or channel of the second communication system, when the shared channel of the first communication system is mapped on the RE (Resource Element), the first transmission resource of the first node can also avoid the signal or channel of the second communication system based on the signaling instruction of the second node.

[0130] In some embodiments, the above method further includes: sending capability information.

[0131] The capability information is used to indicate whether the first node supports avoiding the second transmission resource for rate matching when performing resource element mapping.

[0132] In some embodiments, based on the capability information of the first node, the second node may determine the contents of a time domain resource allocation table (TDRA table) of the first communication system. The TDRA table is used to indicate the starting symbol, the number of available symbols, or the available symbol length of the first communication system in a time slot.

[0133] In some embodiments, the TDRA table may further indicate the position of the collision symbol. On the collision symbol, the first communication system cannot perform data transmission, for example, cannot perform PDSCH transmission or PUSCH transmission.

[0134] As an example, based on the capability information of the first node, if the first node does not support rate matching by avoiding the second transmission resource when performing resource element mapping, the second node determines that the TDRA table of the first communication system adopts the TDRA table of the second communication system, and performs a puncturing operation after performing RE mapping.

[0135] As another example, if the first node supports avoiding the second transmission resource for rate matching when performing resource element mapping, the second node determines that the TDRA table of the first communication system is independent of the TDRA table of the second communication system, that is, the first communication system adopts a new TDRA table.

[0136] Illustratively, the following Table 1 is an example of the first communication system adopting a new TDRA table.

[0137] Table 1 TDRA table

[0138] Among them, a, b, x1, x2, etc. are all natural numbers.

[0139] For example, as shown in the first row of Table 1, in a time slot, the first communication system uses the ath symbol as the starting symbol, the available symbol length is less than x1, and the x1th symbol is a collision symbol. In a time slot, the first communication system may also use the x1+bth symbol as the second starting symbol, and the available symbol length is not limited.

[0140] It should be noted that the above Table 1 is only an example given in the embodiment of the present disclosure. In actual implementation, the TDRA table may contain more or fewer parameters than those in the above Table 1, and the embodiment of the present disclosure does not limit this.

[0141] Exemplarily, as shown in Table 2 below, it is another example of the first communication system adopting a new TDRA table.

[0142] Table 2 TDRA table

[0143] Among them, a1, a2, a3, a4, x1, x2, x3, x4, L, etc. are all natural numbers.

[0144] For example, as shown in the first row of Table 2, in a time slot, the first communication system uses the a1th symbol as the starting symbol, the available symbol length is L (for example, the length used to transmit PDSCH / PUSCH is L symbols), and the L symbols do not include collision symbols. At the same time, the x1th symbol is a collision symbol.

[0145] It should be noted that the above Table 2 is only an example given in the embodiment of the present disclosure. In actual implementation, the TDRA table may contain more or fewer parameters than those in the above Table 2, and the embodiment of the present disclosure does not limit this.

[0146] Illustratively, as shown in Table 3 below, it is another example of the first communication system adopting a new TDRA table.

[0147] Table 3 TDRA table

[0148] The meaning of the examples in Table 3 can be referred to the examples in Table 1 and Table 2 above, and will not be repeated in this disclosure.

[0149] In some embodiments, as shown in Table 1, Table 2 or Table 3 above, row index=1 may indicate that the symbol positions allocated for transmitting PDSCH or for transmitting PUSCH are the 1st to 3rd symbols, or the 5th to 12th symbols.

[0150] It should be noted that the above Table 3 is only an example given in the embodiment of the present disclosure. In actual implementation, the TDRA table may contain more or fewer parameters than those in the above Table 3, and the embodiment of the present disclosure does not limit this.

[0151] In some embodiments, the above method further includes: receiving a physical downlink control channel PDCCH sent by the second node on the first spectrum.

[0152] The PDCCH is used to schedule a first transmission resource on a shared spectrum; the first spectrum does not overlap with the shared spectrum.

[0153] In some embodiments, if the resources available for PDCCH scheduling are insufficient, the first node may schedule PDCCH resources across carriers. PDCCH cross-carrier scheduling includes two modes: primary carrier scheduling and secondary carrier scheduling. In primary carrier scheduling mode, PDCCH can be transmitted using resources in the primary carrier or resources in the secondary carrier. In secondary carrier scheduling mode, PDCCH can be transmitted using resources in the secondary carrier.

[0154] In some embodiments, the first transmission resource of the first communication system does not overlap the control channel of the second transmission resource of the second communication system. The first transmission resource may begin transmitting the PDCCH of the first communication system after the control region of the second transmission resource (e.g., after the first three orthogonal frequency division multiplexing (OFDM) symbols of the shared spectrum). In other words, starting from the fourth OFDM symbol, the PDCCH of the first communication system may be transmitted.

[0155] In some embodiments, the first communication system may directly use the third OFDM symbol and the fourth OFDM symbol in the shared spectrum to transmit the PDCCH of the first communication system.

[0156] It can be understood that in the method provided by the embodiment of the present disclosure, the first transmission resource and the second transmission resource can provide a wider bandwidth for the first communication system (such as a 6G communication system) by sharing the shared spectrum, thereby significantly increasing the capacity of the first communication system. In addition, the shared spectrum provides more spectrum resources for the first communication system, which can improve the coverage and quality of the first communication system. Not only that, based on the shared spectrum, the first communication system and the second communication system can coexist and do not interfere with each other during communication, which ensures the deployment and development of the first communication system and is conducive to system upgrades and network upgrades.

[0157] Referring to Figure 10, which is a flow chart of a wireless communication method provided by an embodiment of the present disclosure, as shown in Figure 10, the wireless communication method provided by an embodiment of the present disclosure is applied to a second node, including the following steps:

[0158] S201. Communicate with a first node in a first communication system based on a first transmission resource.

[0159] The first transmission resource and the second transmission resource of the second communication system share a shared spectrum.

[0161] In some embodiments, the example implementation of the above S201 can refer to the example description in the above steps S101-S102, and the embodiments of the present disclosure will not be repeated here.

[0162] It can be understood that based on the wireless communication method provided by the embodiment of the present disclosure, the first transmission resource shares a shared spectrum with the second transmission resource of the second communication system, so that the first communication system (e.g., a 6G communication system) can obtain more spectrum resources and meet the first communication system's demand for spectrum resources. In addition, on the basis of the first transmission resource and the second transmission resource sharing a shared spectrum, the second node communicates with the first node in the first communication system based on the first transmission resource, thereby avoiding conflicts between the first communication system and the second communication system, and ensuring the smooth deployment and sustainable development of the first communication system during the transition period of coexistence of the first communication system and the second communication system.

[0163] Moreover, the first transmission resource can improve the utilization efficiency of the shared spectrum by sharing the shared spectrum with the second transmission resource of the second communication system, maximize the utilization of the shared spectrum resources, and avoid waste of resources.

[0172] In some embodiments, the above method further includes: sending a third signaling to the first node.

[0173] The third signaling is used to instruct the cell configuration of the first communication system to reuse the cell configuration of the second communication system.
