[0062] This disclosure is not exhaustive, but merely illustrative of some embodiments, and is not intended to limit the scope of protection of this disclosure. Unless otherwise specified, each step in a particular embodiment can be implemented as an independent embodiment, and the steps can be arbitrarily combined. For example, a solution after removing some steps in a particular embodiment can also be implemented as an independent embodiment, and the order of the steps in a particular embodiment can be arbitrarily interchanged.

The description of the descriptive objects is found in the claims or the context of the embodiments, and the use of prefixes should not constitute unnecessary restrictions. For example, if the descriptive object is a "field," the ordinal numbers preceding "field" in "first field" and "second field" do not restrict the position or order of the "fields." "First" and "second" do not restrict whether the "fields" they modify are in the same message, nor do they restrict the order of "first field" and "second field."

Furthermore, the number of descriptive objects is not limited by ordinal numbers and can be one or more. For example, in "first device," the number of "devices" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different. For example, if the object being described is "device", then "first device" and "second device" can be the same device or different devices, and their types can be the same or different.

[0075] In some embodiments, "network" can be interpreted as devices included in the network, such as access network devices, core network devices, etc.

[0076] In some embodiments, "access network device (AN device)" may also be referred to as "radio access network device (RAN device)," "base station (BS)," "radio base station," or "fixed station." In some embodiments, it may also be understood as "node," "access point," "transmission point (TP)," "reception point (RP)," "transmission / reception point (TRP)," "panel," "antenna panel," "antenna array," "cell," "macro cell," "small cell," "femto cell," "pico cell," "sector," "cell group," "serving cell," "carrier," "component carrier," or "bandwidth part (BWP)."

[0078] In some embodiments, the acquisition of data, information, etc., may comply with the laws and regulations of the country where the location is situated.

[0079] In some embodiments, data, information, etc., may be obtained with the user's consent.

[0080] Furthermore, each element, each row, or each column in the table of this disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment.

[0081] In some embodiments, a key difference between LTE and NR systems is that the PBCH in LTE systems is located in the middle of the carrier bandwidth, while in NR systems the PBCH can be located at any position in the carrier bandwidth.

[0082] In some embodiments, during the initial deployment of 5G systems, the existing 4G systems will be gradually replaced, with 5G systems deployed on the original 4G spectrum. This results in scenarios where 5G and 4G systems coexist on the same spectrum. Dynamic spectrum sharing is a technology that ensures the gradual migration of 4G deployments to 5G deployments using existing spectrum, while effectively and dynamically sharing frequency resources when 4G and 5G systems are deployed on the same spectrum. To address the interference issues caused by LTE's PBCH and CRS to NR system transmission when 4G and 5G systems coexist, 5G systems define symbol-level rate-matching for data channel transmission (specifically for LTE's PBCH).

[0083] In some embodiments, in a 5G system, the essential core information of the system, the Master Information Block (MIB), is transmitted through a Synchronization Signal Block (SSB). The specific information bits in the MIB are as follows:

[0084] In other words, the necessary system information, including system frame structure and subcarrier spacing, can be obtained through the MIB in the SSB. The potential location of the PDCCH control resource set (CORESER) #0 of the System Information Block (SIB1) in terms of time and frequency resources is indicated by pdcch-ConfigSIB1 (Remaining Minimum System Information (RMSI) - Physical Downlink Control Channel (PDCCH) - Configuration).

[0085] The pdcch-ConfigSIB1 indicates the time-frequency position of the terminal search type (Type) 0-PDCCH (CORESER#0). pdcch-ConfigSIB1 (e.g., 8-bit information) indicates the time-frequency mapping of CORESET#0. For example, the first 4 bits indicate the common search space for the frequency range of Type 0-PDCCH, and the following 4 bits indicate the time position of Type 0-PDCCH. The mapping is shown in Tables 1 and 2. Table 1 shows the CORESET resource block and time slot symbol set for setting the Type 0 PDCCH search space for a frequency band with a minimum channel bandwidth of 5 MHz or 10 MHz, or a frequency band with a minimum channel bandwidth of 3 MHz and a channel bandwidth greater than 3 MHz, when the SCS of {SS / PBCH block, PDCCH} is {15, 15} kHz. Table 2 shows the PDCCH monitoring timing parameters for the Type 0 PDCCH Common Search Space (CSS) set—SS / PBCH blocks, CORESET multiplexing mode 1, and frequency range (FR1). The SS / PBCH blocks are the synchronization signal and PBCH blocks, which can be abbreviated as SSB.

[0086] Table 1

[0087] Table 2

[0088] Table 1 can be Table 13-1 (TS 38.213-table 13-1) defined in the protocol, and Table 2 can be Table 13-11 (TS 38.213-table 13-11) defined in the protocol.

[0089] In some embodiments, the deployment of 6G systems on existing 5G spectrum may involve spectrum coexistence and sharing between 5G and 6G systems. Figure 1a is a schematic diagram of spectrum coexistence. Figure 1a takes the spectrum coexistence of 5G and 6G systems as an example. As shown in Figure 1a, for the deployment of 6G systems on existing 5G spectrum, for example, on FR1, the spectrum below 3 GHz is co-existent for LTE, NR, and 6G systems. From 3 GHz to 6 GHz, it is co-existent for NR and 6G. On FR2, FR2-1, i.e., 24.25–52.6 GHz, is co-existent for 6G and NR.

[0090] However, in spectrum coexistence scenarios, if different communication protocols transmit PBCH separately, it may cause interference to data transmission and incur significant resource overhead. Furthermore, spectrum coexistence between different communication protocols may be partial, meaning that a dedicated portion of the spectrum may not be coexisting.

[0091] In some embodiments, interference between LTE PBCH and NR system transmissions is primarily mitigated by employing a symbol-level rate-matching scheme to eliminate LTE PBCH interference on the NR system. The parameters defining the rate-matching mode are shown in Table 3.

[0092] Table 3

[0093] This disclosure provides a communication method in which a terminal receives first system information. This first system information is used by terminals supporting a first communication protocol and terminals supporting a second protocol. In other words, by sharing system information across different communication protocols, interference can be avoided, thereby improving communication efficiency.

[0095] As shown in Figure 1b, the communication system 100 includes a terminal 101 and a network device 102.

In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0100] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0101] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0102] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0103] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1b, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1b are illustrative. The communication system may include all or some of the main bodies in FIG1b, or it may include other main bodies outside of FIG1b. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0105] Figure 2a is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. As shown in Figure 2a, this embodiment of the present disclosure relates to a communication method for a communication system 100, the method including:

[0106] In step S2101, terminal 101 receives the first system information sent by network device 102.

[0107] In some embodiments, network device 102 transmits first system information. For example, network device 102 may transmit the first system information in a broadcast manner. For example, the network device may not transmit the first system information unidirectionally to the terminal, but rather broadcast the first system information at a certain frequency location, allowing the terminal to obtain the system information by searching for that frequency location. This disclosure is not limited thereto; for example, in some embodiments, the network device may also transmit the first system information unidirectionally to the terminal.

[0108] In some embodiments, the first system information is used by terminals supporting a first communication protocol and terminals supporting a second communication protocol. In other words, the first system information can be system information shared by terminals supporting the first communication protocol and terminals supporting the second communication protocol. Sharing system information across different communication protocols avoids interference and improves communication efficiency.

[0109] In some embodiments, the first communication protocol is later than the second communication protocol, which can also be understood as the first communication protocol being a newer version of the second communication protocol. For example, the first communication protocol could be 6G, and the second communication protocol could be 5G. 6G is later than 5G, or it can be understood as 6G being a newer version of the communication protocol than 5G. It is understood that this embodiment uses 5G and 6G as examples, but is not limited to them.

[0110] In some embodiments, the first system information may be a MIB, but is not limited thereto.

[0111] In some embodiments, the first system information may be carried in a shared SSB (Service Buffer) between the first and second communication protocols. That is, the first and second communication protocols may share the same SSB to further avoid interference.

[0112] In some embodiments, different CORESET#0 may be defined for the first communication protocol and the second communication protocol.

[0113] For example, taking 5G and 6G as examples, Figure 2b is a schematic diagram illustrating the determination of 5G CORESET#0 and / or 6G CORESET#0 based on MIB according to an embodiment of the present disclosure. As shown in Figure 2b, the first system information can be a MIB, which can be carried by a PBCH (or SSB on the PBCH) shared by 5G and 6G. The MIB can be used to indicate the resource location of at least one of 5G CORESET#0 and / or 6G CORESET#0.

[0114] It is understood that the specific implementation of determining the resource location of CORESET#0 corresponding to the first communication protocol based on the first system information and / or determining the resource location of CORESET#0 corresponding to the second communication protocol based on the first system information can refer to the embodiments of steps S2103 and S2104 of this disclosure, and will not be repeated here.

[0115] Step S2102: Determine whether the communication scenario is a scenario in which the first communication protocol and the second communication protocol share the spectrum based on the first indication information.

[0116] In some embodiments, since the first communication protocol is later than the second communication protocol, the first system information may be system information shared by the second communication protocol to the first communication protocol. If the communication scenario involves the first and second communication protocols sharing spectrum, the second communication protocol may share the system information; if the communication scenario does not involve the first and second communication protocols sharing spectrum, the second communication protocol may not share the system information. That is, if the communication scenario involves the first and second communication protocols sharing spectrum, the first system information may be used for terminals supporting the first communication protocol to access cells using the first communication protocol, and for terminals supporting the second communication protocol to access cells using the second communication protocol. If the communication scenario does not involve the first and second communication protocols sharing spectrum, the first system information may be used only for accessing cells using the second communication protocol. For terminals supporting the first communication protocol, they may switch to the second communication protocol standard and access cells using the second communication protocol. Alternatively, they may receive second system information, which may be used for accessing cells using the first communication protocol. For example, the second system information may be dedicated to terminals supporting the first communication protocol.

[0117] Therefore, the first system information may include first indication information to determine whether the communication scenario involves the first and second communication protocols sharing the same spectrum. This facilitates the terminal supporting the first communication protocol to take further communication measures, such as switching to the second communication protocol or searching for other frequency locations to obtain the second system information, thereby improving communication efficiency.

[0118] In some embodiments, the first indication information is used to indicate whether the communication scenario involves a first communication protocol and a second communication protocol sharing a spectrum. That is, the first indication information can explicitly indicate whether the communication scenario involves a first communication protocol and a second communication protocol sharing a spectrum. For example, the first indication information can be N bits (or redundant N bits) reserved in the first system information. A first value for N bits indicates that the communication scenario involves a first communication protocol and a second communication protocol sharing a spectrum. A second value for N bits indicates that the communication scenario does not involve a first communication protocol and a second communication protocol sharing a spectrum. Exemplarily, N can be 1, the first value can be 1, and the second value can be 0, but this disclosure is not limited to this.

[0119] In some embodiments, the first indication information is used to indicate whether the cell corresponding to the first system information is prohibited from access. When the first indication information indicates that the cell is prohibited from access, the communication scenario is a scenario where the first communication protocol and the second communication protocol share the spectrum; when the first indication information indicates that the cell is not prohibited from access, the communication scenario is not a scenario where the first communication protocol and the second communication protocol share the spectrum. That is, the first indication information can implicitly indicate whether the communication scenario is a scenario where the first communication protocol and the second communication protocol share the spectrum. For example, the first indication information can be a cell prohibition parameter (cellBarred). When the value of cellBarred is barred (prohibited), it is determined that the communication scenario is a scenario where the first communication protocol and the second communication protocol share the spectrum; when the value of cellBarred is notBarred (not prohibited), it is determined that the communication scenario is not a scenario where the first communication protocol and the second communication protocol share the spectrum.

[0120] Step S2103: If the communication scenario is a scenario where the first communication protocol and the second communication protocol share the spectrum, the terminal 101 determines the resource location of the control resource set corresponding to the first communication protocol.

[0121] In some embodiments, if the communication scenario is a scenario where the first communication protocol and the second communication protocol share the spectrum, the terminal 101 determines the resource location of the control resource set corresponding to the first communication protocol.

[0122] Optionally, the first system information includes second indication information, and determining the resource location of the control resource set corresponding to the first communication protocol includes:

[0123] The resource location of the control resource set corresponding to the second communication protocol is determined based on the mapping relationship between the second indication information and the second communication protocol.

[0124] The frequency position of the control resource set corresponding to the first communication protocol is determined based on the frequency position and offset value of the control resource set corresponding to the second communication protocol.

[0125] Optionally, the first system information includes second indication information, and determining the resource location of the control resource set corresponding to the first communication protocol includes:

[0126] The resource location of the control resource set corresponding to the first communication protocol is determined based on the mapping relationship between the second indication information and the first communication protocol.

[0127] The first communication protocol and the second communication protocol have different mapping relationships.

[0128] In some embodiments, the second indication information is a configuration index of a control resource set, and the mapping relationship is a mapping relationship between the configuration index of the control resource set and the resource location of the control resource set. The resource location may include at least one of time-domain resource location and frequency-domain resource location. For example, the second indication information can be used together with the mapping relationship of the first communication protocol to determine the resource location of the control resource set corresponding to the first communication protocol. Alternatively, it can be used together with the mapping relationship of the second communication protocol to determine the resource location of the control resource set corresponding to the second communication protocol.

[0129] Optionally, the protocol predefines a mapping relationship corresponding to the second communication protocol. The terminal can determine the resource location of the control resource set corresponding to the second communication protocol based on the second indication information and the mapping relationship. For example, suppose the mapping relationship between configuration index and resource location in the second communication protocol includes: configuration index #0 maps to resource location #2-0, configuration index #1 maps to resource location #2-1, and configuration index #2 maps to resource location #2-2. When the second indication information is configuration index #0, resource location #2-0 can be determined from the mapping relationship corresponding to the second communication protocol; when the second indication information is configuration index #2, resource location #2-2 can be determined from the mapping relationship corresponding to the second communication protocol. This disclosure does not provide examples for each case. After determining the resource location corresponding to the second communication protocol, the resource location of the control resource set of the first communication protocol can be determined based on the resource location and offset value of the control resource set corresponding to the second communication protocol. For example, the resource location of CORESET #0 corresponding to the second communication protocol = the resource location of CORESET #0 corresponding to the first communication protocol + offset value.

[0130] Optionally, the protocol predefines a mapping relationship corresponding to the first communication protocol. The terminal can determine the resource location of the control resource set corresponding to the first communication protocol based on the second indication information and the mapping relationship corresponding to the first communication protocol. For example, suppose the mapping relationship between configuration index and resource location in the first communication protocol includes: configuration index #0 maps to resource location #1-0, configuration index #1 maps to resource location #1-1, and configuration index #2 maps to resource location #1-2. When the second indication information is configuration index #0, resource location #1-0 can be determined from the mapping relationship corresponding to the first communication protocol; when the second indication information is configuration index #2, resource location #1-2 can be determined from the mapping relationship corresponding to the first communication protocol. This disclosure does not provide examples of all such instances.

[0131] Optionally, if the protocol predefines a mapping relationship between a first communication protocol and a second communication protocol, the second indication information may include a configuration index. However, based on the mapping relationship between the configuration index and different communication protocols, different frequency domain locations can be determined to avoid interference. For example, the first indication information includes configuration index #0. Based on the mapping relationship between configuration index #0 and the second communication protocol, resource location #2-0 can be determined, and based on the mapping relationship between configuration index #0 and the first communication protocol, resource location #1-0 can be determined, so as to facilitate communication operations such as random access at their respective resource locations and avoid interference.

[0132] Optionally, if the protocol predefines a mapping relationship between the first and second communication protocols, the second indication information may include two configuration indices, corresponding to the first and second communication protocols respectively.

[0133] Of course, this disclosure uses two communication protocols as an example, but is not limited to this. For example, in the case of three communication protocols, similarly, the resource location corresponding to the third communication protocol can be determined based on the resource location and offset value corresponding to the first or second communication protocol. This offset value can be the same as or different from the offset value in the above embodiments. As another example, a mapping relationship corresponding to the third communication protocol can be predefined, and the first indication information can include three configuration indices to facilitate the determination of the resource locations corresponding to the three communication protocols respectively. This disclosure does not provide further examples.

[0134] In some embodiments, the second instruction information may be pdcch-ConfigSIB1, but is not limited thereto.

[0135] In some embodiments, the offset value may be predefined in the protocol, but is not limited to this. For example, the offset value may also be configured by the network device.

[0136] In some embodiments, the resource location can be a time-domain resource location, and the unit of the offset value can be milliseconds (ms), slots, and symbols. etc., but not limited to this.

[0137] For example, the unit of the offset value of the time-domain resource location can be ms. Taking 5G and 6G as examples, Figure 2c is a schematic diagram of the resource locations of 5G CORESET#0 and 6G CORESET#0 according to an embodiment of this disclosure. As shown in Figure 2c, SFN represents the frame number, the offset value is 10ms, the diagonal filling is 5G CORESET#0, and the dotted filling is 6G CORESET#0. 5G CORESET#0 and 6G CORESET#0 are 10ms apart in the time domain. That is, if the time domain location of 5G CORESET#0 is determined, adding 10ms can determine the time domain location of 6G CORESET#0.

[0138] For example, the unit of the offset value of the time-domain resource location can be a time slot. Taking 5G and 6G as examples, the time-domain location of 6G can be determined based on Formula 1.

[0139] In Formula 1, Indicates the location of the time slot for 6G transmission. This indicates the location of the 5G transmission time slots. Figure 2d is a schematic diagram of the resource locations of 5G CORESET#0 and 6G CORESET#0 according to an embodiment of this disclosure. As shown in Figure 2c, SFN represents the frame number, and the offset value is n time slots. The diagonal filling represents 5G CORESET#0, and the dotted filling represents 6G CORESET#0. 5G CORESET#0 and 6G CORESET#0 are separated by n time slots in the time domain. That is, if the time domain location of 5G CORESET#0 is determined, adding n time slots can determine the time domain location of 6G CORESET#0.

[0140] In some embodiments, the resource location can be a frequency domain resource location.

[0141] For example, if the time-domain resource locations of the first communication protocol and the second communication protocol are the same, the location of CORESET#0 of the first communication protocol and the location of CORESET#0 of the second communication protocol can be distinguished by the frequency-domain resource locations.

[0142] For example, the offset value of the frequency domain resource location can be in units of Physical Resource Blocks (PRBs). Taking 5G and 6G as examples, Figure 2e is a schematic diagram of the resource locations of 5G CORESET#0 and 6G CORESET#0 according to an embodiment of this disclosure. As shown in Figure 2e, the horizontal axis represents the time domain resource location, the vertical axis represents the frequency domain resource location, and the offset value is 24 resource blocks (RBs). The diagonal filling represents 5G CORESET#0, and the dotted filling represents 6G CORESET#0. As shown in Figure 2b, 5G CORESET#0 and 6G CORESET#0 occupy different frequency domain resource locations on the same time domain resource location. The blank filling part can be the resource location of a shared SSB for 5G and 6G. The shared SSB can be used to carry first system information. That is, the shared SSB can be the same as the frequency domain location of 5G CORESET#0, but different in the time domain, but this disclosure does not limit this.

[0143] For example, the time-domain resource locations of the first communication protocol and the second communication protocol are different, and the frequency-domain resource locations are also different.

[0144] For example, taking 5G and 6G as examples, Figure 2f is a schematic diagram of the resource locations of 5G CORESET#0 and 6G CORESET#0 according to an embodiment of this disclosure. As shown in Figure 2f, the horizontal axis represents the time-domain resource location, and the vertical axis represents the frequency-domain resource location. The time-domain locations of 5G CORESET#0 and 6G CORESET#0 are different, with an interval of t-offset value, and their frequency-domain locations are also different, with an interval of f-offset value. Here, t-offset value t is the offset value of the time-domain resource location, and f-offset value is the offset value of the frequency-domain resource location. The blank areas can represent the resource locations of SSBs shared by 5G and 6G, and these shared SSBs can be used to carry first system information. That is, the shared SSB can occupy a portion of the frequency-domain location of 5G CORESET#0, and is different from the time-domain resource locations of both 5G CORESET#0 and 6G CORESET#0.

[0145] In step S2104, if the communication scenario is not a scenario where the first communication protocol and the second communication protocol share the spectrum, the terminal 101 determines the resource location of the control resource set corresponding to the second communication protocol or receives the second system information.

[0146] Optionally, if the communication scenario is not one where the first and second communication protocols share the same spectrum, terminal 101 determines the resource location of the control resource set corresponding to the second communication protocol. For example, if the terminal switches to the second communication protocol and determines the resource location of the control resource set corresponding to the second communication protocol to access the cell of the second communication protocol, please refer to the embodiment of step S2102 for details, which will not be repeated in this disclosure.

[0147] Optionally, if the communication scenario is not one where the first and second communication protocols share the same spectrum, terminal 101 receives the second system information. For example, if the communication scenario is not one where the first and second communication protocols share the same spectrum, terminal 101 can receive the second system information by searching for other frequency locations. The first system information can be system information dedicated to the first communication protocol, so that the terminal can access the cell of the first communication protocol.

[0148] In some embodiments, the network device may send second system information, for example, by broadcasting. For instance, instead of sending the second system information unidirectionally to the terminal, the network device broadcasts the second system information at a certain frequency location, allowing the terminal to obtain the system information by searching that frequency location if it determines that the communication scenario is not a scenario where the first and second communication protocols share the same spectrum. This disclosure is not limited to this; for example, in some embodiments, the network device may also send the second system information unidirectionally to the terminal.

[0149] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2104. The order of implementation is not limited. For example, step S2101 may be implemented as a standalone embodiment, but is not limited thereto.

[0150] In some embodiments, step S2102 is optional and may be omitted or replaced in different embodiments.

[0151] In some embodiments, steps S2103 and S2104 are optional. In some cases, if the terminal determines that the communication scenario is one in which the first communication protocol and the second communication protocol share the spectrum, step S2103 can be executed, and step S2104 can be omitted. In some cases, if the terminal determines that the communication scenario is not one in which the first communication protocol and the second communication protocol share the spectrum, step S2104 can be executed, and step S2103 can be omitted.

[0152] In some embodiments, other alternative implementations may be described before or after the specification corresponding to FIG2a.

[0174] Figure 5 is a schematic diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 5, this embodiment of the present disclosure relates to a communication method, which includes:

[0175] In step S5101, terminal 101 receives the first system information sent by network device 102.

[0176] In some embodiments, the above methods may include the methods of the embodiments related to the communication system 100, terminal 101, and network device 102, which will not be described again here.

[0177] This disclosure provides a communication method as follows:

[0178] In some embodiments, on 5G and 6G dynamic spectrum sharing frequencies, 5G and 6G systems share SSB and MIB information indications.

[0179] In some embodiments, for 6G terminals, a redundant 1-bit information in the MIB indicates that the current system is a 5G / 6G compatible dynamic spectrum sharing spectrum. Simultaneously, the location of 6Gcoreset#0 is determined using a standard-predefined mapping relationship for the 6Gcoreset#0 frequency resource. In some embodiments, the mapping relationship for the 6Gcoreset#0 resource can be determined by a standard-predefined fixed offset relative to the 5G CORESET#0 resource mapping. That is, using pdcch-ConfigSIB1, the frequency and resource location of the CORESET#0 corresponding to the 5G terminal are determined using the existing 5G resource mapping relationship, while the location of 6Gcoreset#0 is determined using a standard-predefined offset value.

[0180] In some embodiments, the standard predefined offset value can be a fixed offset in the time domain, a fixed offset in the frequency resource, or different offsets in both time and frequency.

[0181] In some embodiments, the mapping relationship of the 6Gcoreset#0 resource can also be a standard predefined time-domain and frequency-domain location mapping relationship, which is indicated by pdcch-ConfigSIB1.

[0182] In some embodiments, on a shared spectrum for 5G and 6G, the network uses a common SSB to indicate MIB information for both 5G and 6G terminals.

[0183] In some embodiments, the MIB information shared by 5G terminals and 6G terminals includes systemFrameNumber, subCarrierSpacingCommon, ssb-SubcarrierOffset, dmrs-TypeA-Position, cellBarred, and intraFreqReselection information.

[0184] In some embodiments, the 6G terminal confirms that it is currently a 5G / 6G spectrum coexistence scenario by using 1 bit of spare or cellBarred.

[0185] In some embodiments, if the 6G terminal detects a spectrum coexistence scenario, it continues to perform 6GCORESET#0 detection.

[0186] In some embodiments, if it is indicated that the current scenario is not a 5G / 6G spectrum coexistence scenario, the 6G terminal may fall back to 5G mode and continue the detection of 5G CORESET#0. Alternatively, the 6G terminal may perform a frequency search to select a potential 6G cell.

[0187] In some embodiments, the 6G terminal uses pdcch-ConfigSIB1 to indicate the frequency and time domain positions based on the existing 5G CORESET#0 mapping, and simultaneously obtains the 6GCORESET#0 position using a predefined offset. For example, the standard predefined offset of 6GCORESET#0 relative to 5G CORESET#0 in the time domain. The same spectral position determines the time-frequency domain position of 6GCORESET#0. For instance, 5G coreset#0SFNc indicates that its 5G coreset#0 is transmitted in an even or odd frame (indicated by the existing pdcch-ConfigSIB1 mapping method), while the time domain position offset of 6GCORESET#0 is 10ms or... Alternatively, it can be transmitted in a slot. That is, 5G coreset#0 and 6G coreset#0 are transmitted in even / odd frames or odd / even frames respectively; 5G coreset#0 and 5G coreset#0 are transmitted at 10ms intervals in the same slot and frequency resource location.

[0188] In some embodiments, 5G coreset#0n0 represents the slot location for 5G coreset#0 transmission, which is indicated using the existing pdcch-ConfigSIB1 mapping method. Where n_offset is the offset of the time domain position of the standard predefined 6Gcorset#0 relative to the 5G coreset#0, in slot units.

[0189] In some embodiments, the standard predefines the frequency domain offset of 6GCORESET#0 relative to 5G CORESET#0 and the time domain position is the same to determine the time frequency domain position of 6GCORESET#0. For example, the starting position of the frequency domain of 6Gcoreset#0 is 5G coreset#0. The offset is measured in PRBs and is a predefined standard offset. Indicates the frequency domain location of 6G. This indicates the frequency domain location of 5G.

[0190] In some embodiments, the standard predefines the frequency domain offset of 6GCORESET#0 relative to 5G CORESET#0 and the time domain offset to determine the position of 6GCORESET#0.

[0191] In some embodiments, on a shared spectrum for 5G and 6G, the network uses a common SSB to indicate MIB information for both 5G and 6G terminals.

[0192] In some embodiments, the MIB information shared by 5G terminals and 6G terminals includes systemFrameNumber, subCarrierSpacingCommon, ssb-SubcarrierOffset, dmrs-TypeA-Position, cellBarred, and intraFreqReselection information.

[0193] In some embodiments, the 6G terminal confirms that it is currently a 5G / 6G spectrum coexistence scenario by using 1 bit of spare or cellBarred.

[0194] In some embodiments, if the 6G terminal detects a spectrum coexistence scenario, it continues to perform 6GCORESET#0 detection.

[0195] In some embodiments, if it is indicated that the current scenario is not a 5G / 6G spectrum coexistence scenario, the 6G terminal may fall back to 5G mode and continue 5G CORESET#0 detection. Alternatively, the 6G terminal may perform a frequency search to select a potential 6G cell.

[0196] In some embodiments, the 6G terminal directly obtains the position of 6Gcoreset#0 in the time and frequency domain through the pdcch-ConfigSIB1 instruction. Here, a new time and frequency resource mapping relationship is defined for the 6G terminal in the standard, such as mapping 6Gcoreset#0 to the same slot and frequency position, but staggering it from 5G coreset#0 in the specific symbol position.

[0197] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0198] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0199] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
