[0031] This disclosure provides a method, apparatus, and storage medium for determining frequency domain location.

[0032] In a first aspect, embodiments of this disclosure propose a method for determining frequency domain location, the method being executed by a terminal, the method comprising:

[0033] Receive non-cell defined synchronization signal block (NCD-SSB);

[0034] Based on the NCD-SSB, the frequency domain location of the first cell definition synchronization signal block CD-SSB and the frequency domain location of the second CD-SSB are determined. The first CD-SSB belongs to the first access network, and the second CD-SSB belongs to the second access network.

[0035] In the above embodiments, after receiving the NCD-SSB, the terminal can determine the frequency domain position of the CD-SSB of the first access network and the frequency domain position of the CD-SSB of the second access network based on the NCD-SSB. This ensures that the terminal can distinguish the frequency domain position of the CD-SSB of different access networks based on the decoded NCD-SSB, without having to make the distinction at the NCD-SSB level. Instead, the distinction is made at the CD-SSB level, which can save the resource consumption of the NCD-SSB level. Furthermore, distinguishing the CD-SSB level can also ensure more stable communication between the terminal and the network device.

[0036] In conjunction with some embodiments of the first aspect, in some embodiments, determining the frequency domain position of the first CD-SSB and the frequency domain position of the second CD-SSB based on the NCD-SSB includes:

[0037] A first offset value and a second offset value are determined based on the NCD-SSB, wherein the second offset value is greater than the first offset value;

[0038] The frequency domain position of the first CD-SSB is determined based on the first offset value;

[0039] The frequency domain position of the second CD-SSB is determined based on the second offset value.

[0040] In the above embodiments, the frequency domain position of CD-SSB in different access networks is determined by different offset values, which realizes that the resources of different CD-SSBs in different access networks can be distinguished by the same NCD-SSB, thus saving the resource consumption of NCD-SSB.

[0041] In conjunction with some embodiments of the first aspect, in some embodiments, determining the first offset value and the second offset value based on the NCD-SSB includes:

[0042] The first offset value and the second offset value are determined based on the first correspondence relationship;

[0043] The first correspondence includes at least two of the following: subcarrier offset, intermediate variable value, first offset value, and second offset value.

[0044] The NCD-SSB includes at least one of the subcarrier offset, control resource set index, and search space index, and the intermediate variable value is determined based on the control resource set index and / or the search space index.

[0045] In the above embodiments, the subcarrier offsets in the NCD-SSB correspond to different offset values ​​in the correspondence relationship. Therefore, based on the first correspondence relationship, the offset values ​​corresponding to different access networks can be determined. Furthermore, based on the offset values, the frequency domain position of the CD-SSB of different access networks can be determined. The correspondence relationship is used to indicate the correlation between different parameters. The corresponding parameters can be determined by looking up the correspondence relationship, which saves resource consumption and improves resource utilization.

[0046] In conjunction with some embodiments of the first aspect, in some embodiments, the difference between the first offset value and the second offset value is the third offset value;

[0047] The absolute value of the third offset value is greater than or equal to the maximum value of the absolute value of the first offset value.

[0048] In the above embodiments, by setting the difference between the first offset value and the second offset value, it is ensured that there is a difference between the first offset value and the second offset value, and that there is no overlap between the first offset value and the second offset value, thereby preventing the situation where the resources of CD-SSBs of different access networks overlap.

[0049] In conjunction with some embodiments of the first aspect, in some embodiments, the NCD-SSB further includes an access network identifier, which is used to indicate the access network to which the NCD-SSB belongs.

[0050] In the above embodiments, different NCD-SSBs can be distinguished by the access network identifier, thus realizing the differentiation of NCD-SSBs.

[0051] In conjunction with some embodiments of the first aspect, in some embodiments, the first offset value is determined based on the product of a first value and a third value, wherein the first value is used to indicate a first identifier of the first access network;

[0052] The second offset value is determined based on the product of the second value and the third value, the second value being used to indicate the second identifier of the second access network, and the first value being less than the second value.

[0053] In the above embodiments, by using the different access network identifiers corresponding to different access networks, the offset values ​​corresponding to different access networks are determined, and then the frequency domain positions of CD-SSBs of different access networks are determined based on the different offset values, ensuring that there is no overlap between the first offset value and the second offset value, thereby preventing the situation where the resources of CD-SSBs of different access networks overlap.

[0054] In conjunction with some embodiments of the first aspect, in some embodiments, the positive and negative values ​​of the first offset value and / or the positive and negative values ​​of the second offset value are determined based on the subcarrier offset and segmentation parameters.

[0055] In the above embodiments, the positive or negative value of the offset can be determined by the subcarrier offset and the segmentation parameter. Distinction is achieved through the mapping relationship between positive and negative offset values ​​and different subcarrier offsets, expanding the types of frequency domain positions of different CD-SSBs determined based on different offset values. That is, the frequency domain GSCN value of the CD-SSB can be greater than or less than the GSCN value of the corresponding nCD-SSB. The aforementioned mapping relationship can include that when the subcarrier offset value is greater than the segmentation parameter, the offset value is negative; when the subcarrier offset value is less than the segmentation parameter, the offset value is positive.

[0056] In conjunction with some embodiments of the first aspect, in some embodiments, determining the first offset value and the second offset value based on the NCD-SSB includes:

[0057] The first offset value is determined based on the second correspondence;

[0058] The second offset value is determined based on the third correspondence;

[0059] The second correspondence includes at least two of the following: subcarrier offset, intermediate variable value, and first offset value.

[0060] The third correspondence includes at least two of the following: subcarrier offset, intermediate variable value, and second offset value.

[0061] The NCD-SSB includes at least one of the subcarrier offset, control resource set index, and search space index, and the intermediate variable value is determined based on the control resource set index and / or the search space index.

[0062] In the above embodiments, different access networks correspond to different correspondences. Therefore, after determining the offset values ​​of different access networks based on different correspondences, the frequency domain positions of CD-SSBs of different access networks can be determined based on different offset values. Since the correspondences are different, the determined first offset value and the second offset value are different. This not only ensures that there is no overlap between the first offset value and the second offset value, but also prevents the resources of CD-SSBs of different access networks from overlapping. Furthermore, the correspondences can save computational resources and improve resource utilization.

[0063] In conjunction with some embodiments of the first aspect, in some embodiments, the difference between the subcarrier offsets of the second correspondence and the third correspondence at the same frequency domain position is a fourth value, which is determined based on the access network identifier of the second access network and a fifth value.

[0064] In conjunction with some embodiments of the first aspect, in some embodiments, determining the first offset value and the second offset value based on the NCD-SSB includes:

[0065] The first offset value is determined based on the fourth correspondence relationship;

[0066] The second offset value is determined based on the fifth correspondence;

[0067] The fourth correspondence includes at least two of the following: subcarrier offset, intermediate variable value, and first offset value.

[0068] The fifth correspondence includes at least two of the following: subcarrier offset, intermediate variable value, and second offset value.

[0069] The NCD-SSB includes the subcarrier offset, and the intermediate variable values ​​included in the fourth correspondence are determined based on a first formula. The first formula is used to calculate the sum of a first product and a second product. The first product is the product of a first coefficient and the control resource set index included in the NCD-SSB, and the second product is the product of a second coefficient and the search space index included in the NCD-SSB.

[0070] The intermediate variable values ​​included in the fifth correspondence are determined based on the second formula, which is used to calculate the sum of the third product and the fourth product. The third product is the product of the third coefficient and the control resource set index included in the NCD-SSB, and the fourth product is the product of the fourth coefficient and the search space index included in the NCD-SSB.

[0071] In the above embodiments, different offset values ​​are calculated by different calculation formulas determined by different correspondences, and the frequency domain positions of CD-SSBs of different access networks are distinguished by different offset values.

[0072] In conjunction with some embodiments of the first aspect, in some embodiments, receiving the NCD-SSB includes: receiving a first NCD-SSB from a first access network and a second NCD-SSB from a second access network;

[0073] The first NCD-SSB is used to determine the frequency domain position of the first CD-SSB, and the second NCD-SSB is used to determine the frequency domain position of the second CD-SSB.

[0074] In the above embodiments, different NCD-SSBs can be distinguished by the access network identifier, thereby ensuring that the CD-SSB of different access networks can be determined based on the different NCD-SSBs. By distinguishing the NCD-SSBs, it is guaranteed that different CD-SSBs can be distinguished in the future, reducing the number of blind detections by the terminal and saving resource consumption.

[0078] The frequency domain positions of the first NCD-SSB and the second NCD-SSB are different, and the synchronization grids of the CD-SSB corresponding to the first NCD-SSB and the CD-SSB corresponding to the second NCD-SSB are the same.

[0079] In the above embodiments, the synchronization grid of CD-SSB is defined as whether the frequency domain position of NCD-SSB is the same, which ensures that the synchronization grid of CD-SSB is distinguishable, and ensures that CD-SSB of different access networks can be accurately distinguished, thereby reducing the number of blind detections by the terminal and saving resource consumption.

[0163] Figure 1 is an exemplary schematic diagram of the architecture of a communication system provided according to an embodiment of the present disclosure.

[0164] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0165] In some embodiments, terminal 101 includes, for example, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home, but is not limited thereto.

[0166] In some embodiments, the access network device 102 may be a node or device that connects a terminal to a wireless network. The access network device may include at least one of the following in a 5G communication system: an evolved Node B (eNB), a next-generation eNB (ng-eNB), a next-generation Node B (gNB), a node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open RAN, a cloud RAN, a base station in other communication systems, and an access node in a Wi-Fi system, but is not limited thereto.

[0167] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. 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.

[0168] 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.

[0169] 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 the evolved packet core (EPC), 5G core network (5GCN), and next-generation core (NGC).

[0170] 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.

[0171] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​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.

[0172] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), Super 3G, IMT-Advanced, 4th Generation Mobile Communication System (4G), 5th Generation Mobile Communication System (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, ultra-wideband (UWB), Bluetooth (a registered trademark), public land mobile network (PLMN) networks, device-to-device (D2D) systems, machine-to-machine (M2M) systems, internet of things (IoT) systems, vehicle-to-everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0173] In some embodiments of a 5G system, to ensure a user's initial access to a cell and acquisition of time and frequency synchronization, the network needs to send a synchronization information block (SSB) and a system information block 1 (SIB1) to enable the terminal to complete downlink synchronization and cell information acquisition. SIB1, as information carried on the physical downlink shared channel (PDSCH), needs to carry related control messages through the (type 0) physical downlink control channel (PDCCH).

[0174] The time-frequency resources of type 0PDCCH are determined through the control resource set (Coreset) 0 and the search space (Search Space) 0. For example, the UE determines them by decoding k in the master indication block (MIB). ssb The frequency domain location of the Channel Raster common resource block (CRB) is obtained. The UE decodes pdcch-ConfigSIB1 in the MIB, obtaining the index of controlResourceSetZero in the index table using the high four bits and the index of searchSpaceZero using the low four bits. Based on the offset (RBs) indicated by the corresponding index, the time-frequency domain location of Coreset 0 / SS0 is obtained. The UE then decodes subCarrierSpacingCommon and carrier bandwidth related information in the MIB to obtain the appropriate table.

[0175] In some embodiments, SSBs include CD-SSB and NCD-SSB. CD-SSB is used for access and requires the indication of the corresponding type 0PDCCH and SIB1 information. NCD-SSB itself does not carry network access information, but it will indicate the nearest CD-SSB according to the following rules:

[0176] Rule 1: The GSCN of the most recent SSB (cd-SSB) containing Coreset is GSCN for NCD-SSB This is the offset value of GSCN.

[0177] Rule 2: The GSCN value of the most recent SSB (cd-SSB) containing the Coreset is not located in Within the range, among which, and They are determined by the control resource set 0 (controlResourceSetZero) and search space 0 (searchSpaceZero) in pdch-configsib1, respectively.

[0178] Figure 2 is an interactive schematic diagram illustrating a method for determining frequency domain location according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a method for determining frequency domain location, the method including:

[0179] Step S2101: The network device sends an NCD-SSB.

[0180] In some embodiments, the terminal receives the NCD-SSB. It should be noted that step S2101 above can also involve the network device sending the NCD-SSB to the terminal, and correspondingly, the terminal receives the NCD-SSB sent by the network device.

[0181] In some embodiments, the network device schedules time-domain resources and / or frequency-domain resources for the terminal to send NCD-SSBs. Subsequently, the network device sends NCD-SSBs based on the scheduled time-domain resources and / or frequency-domain resources, and the terminal receives NCD-SSBs based on the scheduled time-domain resources and / or frequency-domain resources.

[0182] It should be noted that the NCD-SSB sent by the network device in this embodiment can be a public SSB, or it can be understood that the NCD-SSB is applicable to both the first access network and the second access network. The first access network and the second access network are different. In some embodiments, the first access network is a 5G access network and the second access network is a 6G access network. Alternatively, the first access network and the second access network can be other types of access networks, which are not limited in this embodiment.

[0183] In other embodiments, the NCD-SSB sent by the network device in this disclosure may be two different NCD-SSBs.

[0184] Optionally, the network device transmitting the NCD-SSB may further include transmitting the NCD-SSB of the first access network and the NCD-SSB of the second access network. Correspondingly, the terminal receiving the NCD-SSB includes receiving the NCD-SSB of the first access network and the NCD-SSB of the second access network.

[0185] Optionally, the control resource set index included in the first NCD-SSB is the same as the control resource set index included in the second NCD-SSB.

[0186] Optionally, the search space index included in the first NCD-SSB is the same as the search space index included in the second NCD-SSB.

[0187] Optionally, the frequency domain position of the first NCD-SSB is the same as that of the second NCD-SSB, but the synchronization grids of the CD-SSBs corresponding to the first and second NCD-SSBs are different.

[0188] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transmit,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0189] In step S2102, the terminal determines the frequency domain position of the first CD-SSB and the frequency domain position of the second CD-SSB based on the NCD-SSB.

[0190] In some embodiments, the first CD-SSB belongs to the first access network, and the second CD-SSB belongs to the second access network. In this embodiment of the present disclosure, the terminal can determine the frequency domain location of different CD-SSBs in the first and second access networks based on the NCD-SSB, thus realizing the differentiation of the frequency domain location of CD-SSBs in different access networks based on the NCD-SSB.

[0191] In some embodiments, the terminal determines a first offset value and a second offset value based on the NCD-SSB, determines the frequency domain position of the first CD-SSB based on the first offset value, and determines the frequency domain position of the second CD-SSB based on the second offset value. The second offset value is greater than the first offset value.

[0192] For example, both the first offset value and the second offset value are offset based on the frequency domain position of the NCD-SSB, so that the frequency domain position of the CD-SSB after offset is different.

[0193] In this embodiment of the disclosure, the terminal determines two different first offset values ​​and second offset values ​​based on the NCD-SSB, ensuring that the first CD-SSB and second CD-SSB of different access networks can be determined based on the different first offset values ​​and second offset values.

[0194] Optionally, the terminal determines the first offset value and the second offset value based on the first correspondence relationship. The first correspondence relationship includes a correspondence between subcarrier offset, intermediate variable value, and at least two of the first and second offset values. The NCD-SSB includes at least one of subcarrier offset, control resource set index, and search space index. The intermediate variable value is determined based on the control resource set index and search space index. In this embodiment, since the first correspondence relationship includes at least two of the subcarrier offset, intermediate variable value, first offset value, and second offset value, and the NCD-SSB includes subcarrier offset, the first and second offset values ​​can be determined based on the subcarrier offset included in the NCD-SSB and the first correspondence relationship. It should be noted that if the first offset value can be determined, the first correspondence relationship includes at least the correspondence between the subcarrier offset and the first offset value. If the second offset value can be determined, the first correspondence relationship includes at least the correspondence between the subcarrier offset and the second offset value.

[0195] For example, the first correspondence includes the correspondence between subcarrier offset, intermediate variable value, first offset value and second offset value. See Table 1, which gives the intermediate variable value, first offset value and second offset value corresponding to different subcarrier offsets.

[0196] Table 1

[0197] It should be noted that the terminal can determine the type of NCD-SSB based on the subcarrier offsets included in the NCD-SSB. For example, it can determine whether the subcarrier offset falls within a threshold range, thereby determining which frequency band and access network's SSB the NCD-SSB belongs to. The minimum value of this threshold range is specified by the network device or communication protocol. The maximum value of this threshold range varies depending on the FR frequency band, is used for different access networks, and is also specified by the network device or communication protocol.

[0198] In some embodiments, the difference between the first offset value K1 and the second offset value K2 is the third offset value K3. In some embodiments, the absolute value of the third offset value K3 is greater than or equal to the maximum absolute value of the first offset value K1. For example, if the maximum absolute value of the first offset value K1 is 768, then the absolute value of the third offset value K3 should be greater than or equal to 768.

[0199] In some embodiments, the first offset value K1 is calculated using the following formula: K1=(-1)^{floor(k ssb / 27)}{mod(768+(k ssb -27)*256+Var i ,768)+1}, where k ssbFor subcarrier offset, Var i For intermediate variable values, floor(.) rounds down, and mod(.) is the modulo function. i The following formula is used to determine it: X*f(controlResourceSetZero)+Y*g(searchspaceZero), where X and Y are constants.

[0200] In some embodiments, the second offset value K2 is calculated using the following formula: K2=(-1)^{floor(kssb / 27)}{mod(768+K3+(k ssb -27)*256+Var i K2 = (-1)^{floor(kssb / 27)}{mod(768+768+(k ssb -27)*256+Var i ,768)+1}.

[0201] Based on the first offset value and the second offset value given in the above embodiments, the parameter values ​​shown in Table 1 can be obtained.

[0202] It should be noted that in the above embodiment, the positive and negative values ​​of the parameter are implemented using (-1)^{floor(kssb / 27)} as an example. In another embodiment, 27 in the above embodiment is actually a segmentation parameter, which is used to specify on which subcarrier offset the positive and negative values ​​of the first offset value or the second offset value are adjusted.

[0203] In some embodiments, the positive and negative values ​​of the first offset value K1 and / or the second offset value K2 are determined based on the subcarrier offset and the segmentation parameter. Alternatively, it can be understood that the segmentation parameter actually segments the subcarrier offset values, thereby ensuring that the first offset value K1 and the second offset value K2 are positive in some parts of the subcarrier offset, and negative in other parts of the subcarrier offset.

[0204] Optionally, the first offset value K1 is expressed by the following formula: K1=(-1)^{floor(k ssb / P)}{mod(768+(k ssb -P)*256+Var i,768)+1}, where P is the segmentation parameter. Optionally, the second offset value K2 is calculated using the following formula: K2=(-1)^{floor(kssb / P)}{mod(768+K+(k ssb -P)*256+Var i ,768)+1},P is the segmentation parameter.

[0205] In some embodiments, the NCD-SSB further includes an access network identifier, which indicates the access network to which the NCD-SSB belongs. Optionally, the access network identifier is a MIB identifier. For example, the MIB identifier is represented using bits from the System Minimum Information (MIB).

[0206] Optionally, since the NCD-SSB includes an access network identifier, and the access network identifier can indicate the identifier of different access networks through different values, the first offset value and the second offset value can be determined based on the access network identifier.

[0207] Optionally, the first offset value is determined based on the product of a first value and a third value, where the first value is used to indicate the first identifier of the first access network. In this embodiment of the disclosure, the first identifier of the first access network is indicated by the first value, therefore the first offset value can be determined based on the product of the first value and the third value. The third value is 768, or it can be any other value; this embodiment of the disclosure does not limit this.

[0208] Optionally, the second offset value is determined based on the product of a second value and a third value, where the second value indicates the second identifier of the second access network, and the first value is less than the second value. In this embodiment, the second identifier of the second access network is indicated by the second value, therefore the first offset value can be determined based on the product of the second value and the third value. The third value is 768, or it can be any other value; this embodiment does not limit the specific value.

[0209] For example, the first offset value and the second offset value are represented by the following formula: (-1)^{floor(k ssb / 27)}{mod(768*M+(k ssb -27)*256+Var i ,768)+1}. Where M represents the MIB indication, or it can also represent the access network identifier. When M is 1, the above formula yields the first offset value; when M is 2, the above formula yields the second offset value.

[0210] In some embodiments, the positive and negative values ​​of the first offset value and / or the positive and negative values ​​of the second offset value are determined based on the subcarrier offset and segmentation parameters. Optionally, based on the above embodiments, the first offset value and the second offset value are expressed by the following formula: (-1)^{floor(k ssb / P)}{mod(768*M+(k ssb -P)*256+Var i ,768)+1}。 P is the segmentation parameter. Wherein, when M is 1, the above formula yields the first offset value, and when M is 2, the above formula yields the second offset value.

[0211] In some embodiments, the terminal may also determine the first offset value based on the second correspondence and the second offset value based on the third correspondence.

[0212] The second correspondence includes at least two of the following: subcarrier offset, intermediate variable value, and first offset value; the third correspondence includes at least two of the following: subcarrier offset, intermediate variable value, and second offset value; the NCD-SSB includes at least one of the following: subcarrier offset, control resource set index, and search space index, and the intermediate variable value is determined based on the control resource set index and the search space index.

[0213] In this embodiment of the disclosure, the different subcarrier offsets included in the second correspondence correspond to at least one of different intermediate variable values ​​and a first offset value. Therefore, based on the subcarrier offsets included in the NCD-SSB, at least one of the corresponding intermediate variable values ​​and a first offset value can be determined. Furthermore, the different subcarrier offsets included in the third correspondence correspond to at least one of different intermediate variable values ​​and a second offset value. Therefore, based on the subcarrier offsets included in the NCD-SSB, at least one of the corresponding intermediate variable values ​​and a second offset value can be determined.

[0214] It should be noted that the subcarrier offsets included in the second correspondence are different from those included in the third correspondence, but there is a correlation between the subcarrier offsets included in the second correspondence and those included in the third correspondence.

[0215] Optionally, the difference between the subcarrier offsets at the same frequency domain position in the second and third correspondences is a fourth value, which is determined based on the access network identifier of the second access network and a fifth value. For example, the access network identifier of the second access network is 1, and the fifth value is 1. Optionally, the second offset value in the third correspondence is expressed by the following formula: k ssb,6G =k ssb,5G +M*offset. Where M represents the access network identifier of the second access network, with a value of 1, and offset is the fifth value, with a value of 1.

[0216] For example, the second correspondence includes different subcarrier offsets corresponding to different intermediate variable values ​​and first offset values, while the third correspondence includes different subcarrier offsets corresponding to different intermediate variable values ​​and second offset values. Referring to Table 2, the second correspondence includes subcarrier offsets of 24 and 27, while the third correspondence includes subcarrier offsets of 25 and 28.

[0217] Table 2

[0218] In some embodiments, the terminal determines a first offset value based on a fourth correspondence and a second offset value based on a fifth correspondence. The fourth correspondence includes at least two of the following: subcarrier offset, intermediate variable value, and first offset value; the fifth correspondence includes at least two of the following: subcarrier offset, intermediate variable value, and second offset value; and NCD-SSB includes subcarrier offset.

[0219] Furthermore, the intermediate variable values ​​included in the fourth correspondence are determined based on the first formula. The first formula calculates the sum of the first product and the second product. The first product is the product of the first coefficient and the index of the control resource set included in the NCD-SSB, and the second product is the product of the second coefficient and the index of the search space included in the NCD-SSB. For example, if the first coefficient is 16, the index of the control resource set included in the NCD-SSB is represented by `controlResourceSetZero`, the second coefficient is 1, and the index of the search space included in the NCD-SSB is represented by `searchSpaceZero`, then the intermediate variable value included in the fourth correspondence is 16 × `controlResourceSetZero` + `searchSpaceZero`.

[0220] The intermediate variable values ​​included in the fifth correspondence are determined based on the second formula. The second formula calculates the sum of the third and fourth products. The third product is the product of the third coefficient and the index of the control resource set included in the NCD-SSB, and the fourth product is the product of the fourth coefficient and the index of the search space included in the NCD-SSB. For example, if the third coefficient is 1, the index of the control resource set included in the NCD-SSB is represented by `controlResourceSetZero`, the fourth coefficient is 16, and the index of the search space included in the NCD-SSB is represented by `searchSpaceZero`, then the intermediate variable value included in the fifth correspondence is (`controlResourceSetZero + 16 × searchSpaceZero + 1`) mod 255. It should be noted that the 1 in the intermediate variable value included in the fifth correspondence is used to distinguish the overlap of intermediate variables and offset values ​​corresponding to code points with the same configuration, such as (0,0) and (15,15), thus preventing the fourth and fifth correspondences from having the same code point, which would make it impossible to distinguish the CD-SSB.

[0221] In some embodiments, the terminal determines a first range and a second range based on the NCD-SSB, determines the frequency domain location of the first CD-SSB based on the first range, and determines the frequency domain location of the second CD-SSB based on the second range. The first range does not include the frequency domain location of the first CD-SSB of the first access network, and the second range does not include the frequency domain location of the second CD-SSB of the second access network.

[0222] Optionally, the terminal can determine the frequency band and access network type of its FR based on the subcarrier offset of the received NCD-SSB, and can also determine the starting frequency domain position and ending frequency domain position based on the values ​​of the control resource set index and search space index included in the NCD-SSB, respectively.

[0223] In this embodiment of the present disclosure, the terminal can determine a first range excluding the frequency domain location of the first CD-SSB and a second range excluding the frequency domain location of the second CD-SSB. The first CD-SSB belongs to the first access network and the second CD-SSB belongs to the second access network. Therefore, the first CD-SSB and the second CD-SSB can be distinguished by the determined first range and the second range, thereby realizing the differentiation of the frequency domain location of CD-SSBs of different access networks and ensuring the accuracy of the determined frequency domain location of CD-SSBs of different access networks.

[0224] Optionally, the terminal determines a first start frequency domain position and a first end frequency domain position based on the NCD-SSB, and determines a first range based on the frequency domain position of the NCD-SSB and the first start frequency domain position and the first end frequency domain position; and the terminal can also determine a second start frequency domain position and a second end frequency domain position based on the NCD-SSB, and determine a second range based on the frequency domain position of the NCD-SSB and the second start frequency domain position and the second end frequency domain position.

[0225] In this embodiment of the disclosure, the first range has a start position and an end position, and the second range also has a start position and an end position. Therefore, the terminal can determine the first start frequency domain position and the first end frequency domain position of the first range, and the second start frequency domain position and the second end frequency domain position of the second range, thereby determining the first range and the second range.

[0226] Optionally, the difference between the first starting frequency domain position and the second starting frequency domain position is a sixth value, and the difference between the first ending frequency domain position and the second ending frequency domain position is a seventh value. It should be noted that the sixth value and the seventh value can be the same or different, and this embodiment does not limit this.

[0227] Optionally, the method for determining the first starting frequency domain position is different from the method for determining the second starting frequency domain position, and the method for determining the first ending frequency domain position is different from the method for determining the second ending frequency domain position.

[0228] For example, the first starting frequency domain position is the product of the fifth coefficient and the control resource set index, and the second starting frequency domain position is the product of the sixth coefficient and the control resource set index. As another example, the first ending frequency domain position is the product of the seventh coefficient and the search space index, and the second ending frequency domain position is the product of the eighth coefficient and the search space index.

[0229] For example, the first starting frequency domain position is the product of the fifth coefficient and the control resource set index; the second starting frequency domain position is the sum of the first starting frequency domain position and the sixth value; the first ending frequency domain position is the product of the seventh coefficient and the search space index; and the second ending frequency domain position is the sum of the first ending frequency domain position and the seventh value.

[0230] For example, the second range is represented by the following formula: Offect1 is the sixth value, and offect2 is the seventh value.

[0231] Optionally, the network device transmitting the NCD-SSB may further include transmitting the NCD-SSB of the first access network and the NCD-SSB of the second access network. Correspondingly, the terminal receiving the NCD-SSB includes receiving the NCD-SSB of the first access network and the NCD-SSB of the second access network.

[0232] Optionally, the NCD-SSB of the first access network is used to determine the frequency domain location of the first CD-SSB, and the NCD-SSB of the second access network is used to determine the frequency domain location of the second CD-SSB.

[0233] In some embodiments, the control resource set index included in the first NCD-SSB is the same as the control resource set index included in the second NCD-SSB.

[0234] In some embodiments, the search space index included in the first NCD-SSB is the same as the search space index included in the second NCD-SSB.

[0235] In some embodiments, the frequency domain position of the first NCD-SSB is the same as that of the second NCD-SSB, but the synchronization grids of the CD-SSBs corresponding to the first NCD-SSB and the second NCD-SSB are different.

[0236] In some embodiments, the frequency domain position of the first NCD-SSB is different from that of the second NCD-SSB, and the synchronization grid of the CD-SSB corresponding to the first NCD-SSB and the CD-SSB corresponding to the second NCD-SSB is the same.

[0237] In this embodiment of the disclosure, if the NCD-SSB can directly distinguish the access network, then when determining the frequency domain position of the CD-SSB based on the NCD-SSB, the frequency domain position of the CD-SSB of the corresponding access network can be determined directly based on the NCD-SSB of different access networks, ensuring that the determined CD-SSB corresponds to different access networks.

[0238] In step S2103, the network device sends CD-SSB based on the frequency domain location of CD-SSB in different access networks.

[0352] Figure 4 is a flowchart illustrating a method for determining a frequency domain location according to an embodiment of the present disclosure. As shown in Figure 4, the present disclosure relates to a method for determining a frequency domain location, the method including:

[0353] Step S4101: Define the GSCN offset values ​​that are different from the common NCD SSB for 5G RAT and 6G RAT to determine the corresponding CD SSB position.

[0354] In some embodiments, the common NCD SSB is applicable to 5G or 6G. Additionally, the GSCN offset includes two values: a first offset value and a second offset value as described in the above embodiments. The first offset value belongs to the 5G RAT, and the second offset value belongs to the 6G RAT.

[0355] In some embodiments, step S4101 is similar to steps S2101-S2102 in the above embodiments.

[0356] Example 0:

[0357] For a given ncd SSB, different Global Synchronization Channel Number (GSCN) offsets are configured for 5G RAT and 6G RAT, wherein the GSCN offset is similar to the first offset value and the second offset value in the foregoing embodiments.

[0358] Optionally, the decision condition of ncd SSB still uses the value range of kssb: Condition 1: kmin < kssb ≤ kmax for FRX, {X=1,2,3,...}, it is determined as a first type of ncd SSB; marking the sequence number of this SSB as i, the PBCH content of this SSBi includes the following information:

[0359] (1)Kssb

[0360] (2) Value of {Coreset / SearchSpace 0}, wherein the intermediate variable Vari is obtained by the following formula X*f(controlResourceSetZero)+Y*g(searchspaceZero).

[0361] In some embodiments, obtaining the with different values from According to the table, a method for obtaining is as follows:

[0362] Embodiment 0-0 Based on the foregoing formula, a method for obtaining is as follows:

[0363] Optionally, the foregoing conversion is characterized in that Noffset,6G is obtained by adding an offset to Noffset,5G, and this offset is characterized by being the maximum value (note: this value can ensure that when the 5G and 6G ncd SSB GSCN references overlap, the cd SSBs indicated by the GSCN offsets of 5G and 6G do not overlap at all).

[0364] Optionally, the foregoing conversion is further characterized in that there is a kssb, and there is a segmentation parameter Pthres for splitting kssb, for example, the value is Pthres, which is used to determine the offset of 6G RAT.

[0365] Wherein, Embodiment 0-1

[0366] Based on the above formula, one way to obtain The method is as follows:

[0367] Optionally, the aforementioned transformation feature lies in the use of MIB indication in the offset, in short:

[0368] 5G MIB indication = 1

[0369] 6G MIB indication = 2

[0370] Examples 0-2, without adding 6G specific The premise is that the network knows for certain that within a certain frequency band, only a portion of... Used

[0371] In this example, only kssb = 24 / 27 corresponds to this. If it is used, then the corresponding 6G GSCN used value can be 25 / 28, in addition to the values ​​shown in 0-1 and 0-2 above. In addition to the distinctions already made, we can add the following distinction k ssb,6G =k ssb,5G +MIB indication*offset

[0372] In this example, MIB indication = 1 (6G), offset = 1 (the value of offset is fixed).

[0373] Examples 0-3, formula differences

[0374] 5G: 16×controlResourceSetZero+searchSpaceZero

[0375] 6G: (controlResourceSetZero+16×searchSpaceZero+1)mod 255

[0376] To prevent the overlap of code points with the same configuration, such as (0,0) and (15,15),

[0377] Examples 0-4,

[0378] In some embodiments, the network ensures that the corresponding kssb and controlResourceSetZero, searchSpaceZero information of the ncd SSB sent on different sync rasters for 5G and 6G are the same.

[0379] In some embodiments, the UE ensures that the corresponding kssb and controlResourceSetZero, searchSpaceZero information of the ncd SSB received on different sync rasters for 5G and 6G are the same.

[0380] In some embodiments, the network ensures that the corresponding cd SSB rasters of the ncd SSBs sent on different sync rasters for 5G and 6G are different.

[0381] In some embodiments, the UE ensures that the corresponding CD SSB raster is different on the ncd SSB received on different sync rasters for 5G and 6G.

[0382] Example 1:

[0383] In some embodiments, the decision condition for ncd SSB still uses the range of values ​​for kssb:

[0384] Condition 2: kssb = X for FRX, {X = 1, 2, 3, ...}, is determined to be a second-class NCD SSB; let the index of this SSB be i, and the PBCH content of this SSB contains the following information:

[0385] (1)Kssb.

[0386] (2) The values ​​of Coreset / SearchSpace 0 correspond to respectively and

[0387] in, The range in the MIB indication where there is no cd SSB corresponding to the RAT SSB.

[0388] Optionally, and The above formula can be used.
