For any path in multipath propagation, the time and phase of the beam reaching the terminal's receiving antenna array are equally spaced.

[0109] In some embodiments, for a terminal in a near-field communication scenario, the electromagnetic waves received by the terminal are spherical waves. Figure 1D is a schematic diagram of near-field beam propagation according to an embodiment of the present disclosure. As shown in Figure 1D, in a near-field communication scenario, the beam targeted at the terminal is a three-dimensional (3D) beam that surrounds the target terminal. For any path in multipath propagation, the time and phase of the beam arriving at the terminal's receiving antenna array are no longer equidistant.

[0110] That is, for far-field terminals, the directions from multiple antenna ports of a network device (e.g., a base station) to the terminal are the same. For near-field terminals, the beam directions from different antenna ports of a network device (e.g., a base station) to the terminal may be different.

[0111] For near-field or far-field communication scenarios, it is assumed that the network device has 32 transmission beam directions. For far-field communication scenarios, it is only necessary to send 32 reference signal resources based on 32 beam directions at any one port. For near-field communication scenarios, the first beam direction (one of the 32 beam directions) sent by the network device at the first port and the direction of the first beam sent by the network device at the second port have different received signal strengths reaching the terminal. Therefore, the network device needs to send 32 beam directions separately on each port.

[0112] If traditional beam management is used, network equipment needs to send reference signals for beam measurement in a single-port manner. The terminal's scanning time will increase exponentially with the increase in the number of ports, resulting in a large amount of resource overhead.

[0113] Therefore, it is necessary to propose a multi-port reference signal resource configuration method to reduce the resource overhead of the terminal.

[0114] FIG2 is an interactive diagram of a resource configuration method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to a resource configuration method for a communication system 100, the method comprising:

[0115] Step S2101 : The network device 102 sends first configuration information to the terminal 101 .

[0116] In some embodiments, the terminal 101 receives first configuration information sent by the network device 102, where the first configuration information is used to configure reference signal resources corresponding to multiple ports.

[0117] Exemplarily, the first configuration information includes reference signal resource configuration information, and the first configuration information configures the reference signal resources of multiple ports through the included reference signal resource configuration information.

[0118] It should be noted that a multi-port reference signal resource refers to a reference signal resource with a port number greater than or equal to 2.

[0119] It is understandable that, through the reference signal resource configuration information in the first configuration information, the reference signal resources of multiple ports can be configured for the terminal 101, thereby enabling the terminal 101 to perform measurements based on the configured reference signal resources of multiple ports and obtain corresponding measurement reports. For example, the terminal 101 measures the Layer 1 Reference Signal Received Power (L1-RSRP) of the reference signal resources of the multiple ports and / or measures the Layer 1 Signal-to-noise And Interference Ratio (L1-SINR) of the reference signal resources of the multiple ports, thereby obtaining corresponding measurement reports.

[0120] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0121] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0122] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0123] In some embodiments, the terms "synchronization signal (SS)", "synchronization signal block (SSB)", "reference signal (RS)" and the like can be used interchangeably.

[0124] Step S2102 , the terminal 101 sends a measurement report to the network device 102 .

[0125] In some embodiments, before the terminal 101 sends the measurement report to the network device 102, the terminal 101 also determines the measurement report.

[0126] Exemplarily, the terminal 101 obtains a measurement report by measuring the multi-port reference signal resource configured by the reference signal resource configuration information (for example, measuring its L1-RSRP or L1-SINR).

[0127] In some embodiments, the measurement report includes at least one of the following: a reference signal resource identifier and port information; a quality parameter and port information; a reference signal resource identifier, a quality parameter and port information.

[0128] The port information may include, for example, a port identifier or a port group identifier of the reference signal resource, etc. That is, the port information is used to identify information of each port of a reference signal resource having multiple ports.

[0129] The reference signal resources include: Channel Status Information-Reference Signal (CSI-RS) and / or Synchronization Signal and PBCH block (SSB).

[0130] Based on this, the measurement report can also be understood as including at least one of the following: reference signal resource identifier and port identifier; reference signal resource identifier and port group identifier; quality parameter and port identifier; quality parameter and port group identifier; reference signal resource identifier, quality parameter and port identifier; reference signal resource identifier, quality parameter and port group identifier.

[0131] In some embodiments, the quality parameter is a quality parameter corresponding to a reference signal resource identifier and a port identifier.

[0132] In some embodiments, the quality parameter is a quality parameter corresponding to a reference signal resource identifier and a port group identifier.

[0133] In some embodiments, the quality parameter is a quality parameter corresponding to a port identifier.

[0134] In some embodiments, the quality parameter is a quality parameter corresponding to the port group identifier.

[0135] In some embodiments, the quality parameter comprises L1-RSRP or L1-SINR.

[0136] In some embodiments, the terms "port identification", "port index", "port index" and the like can be used interchangeably.

[0137] In some embodiments, terms such as “port group identifier”, “port group index”, and “port group index” can be used interchangeably.

[0138] It should be noted that there is a correspondence between ports and port groups. For example, a port group can be understood as a collection of multiple ports.

[0139] In some embodiments, the correspondence between the ports and the port groups may be determined in the following manners: based on a default rule, or through second configuration information.

[0140] In some embodiments, the correspondence relationship (correspondence relationship between ports and port groups) determined based on the default rule may be at least one of the following 1) to 3):

[0141] 1) The port group corresponding to each port group identifier includes N ports with consecutive port identifiers (where N is an integer greater than or equal to 2).

[0142] Exemplarily, the reference signal resource has eight ports, namely: port 0#, port 1#, port 2#, port 3#, port 4#, port 5#, port 6#, and port 7#. If the port groups are determined based on the continuity of the port identifiers, the eight ports are divided into two port groups. For example, the reference signal resource may have two port groups, port group A# and port group B#. Port group A# includes the following ports: port 0#, port 1#, port 2#, and port 3#. Port group B# includes the following ports: port 4#, port 5#, port 6#, and port 7#.

[0143] 2) The port group corresponding to each port group identifier includes N ports with equally spaced port identifiers.

[0144] Exemplarily, the reference signal resource has eight ports, namely: port 0#, port 1#, port 2#, port 3#, port 4#, port 5#, port 6#, and port 7#. If the port group is determined based on the method of equally spaced port identifiers (for example, the interval is 1), the eight ports are determined as two port groups. For example, the reference signal resource may have two port groups, port group A# and port group B#. The ports in port group A# are: port 0#, port 2#, port 4#, and port 6#. The ports in port group B# are: port 1#, port 3#, port 5#, and port 7#.

[0145] 3) Determine, based on the protocol, the port identifiers contained in each port group in the port group corresponding to the port group identifier.

[0146] Exemplarily, the reference signal resource has eight ports, namely: port 0#, port 1#, port 2#, port 3#, port 4#, port 5#, port 6#, and port 7#. If the port group is determined based on a protocol-determined method (for example, the protocol predetermines that multiple ports are divided into the same port group), for example, the reference signal resource may have two port groups, port group A# and port group B#. The ports in port group A# are: port 0#, port 1#, port 4#, and port 5#. The ports in port group B# are: port 2#, port 3#, port 6#, and port 7#.

[0147] In some embodiments, the correspondence relationship (correspondence relationship between ports and port groups) determined based on the second configuration information may be at least one of the following: the number of ports included in each port group; and port identifiers of ports included in each port group.

[0148] It should be noted that the second configuration information may be the first configuration information, or may be other configuration information except the first configuration information.

[0149] In some embodiments, if the port identifiers of the ports included in the port group corresponding to each port group identifier are continuous, the number of ports included in each port group can be configured through the second configuration information to achieve configuration of the port group, wherein the starting port identifier is determined by default.

[0150] Exemplarily, the reference signal resource has eight ports, namely: port 0#, port 1#, port 2#, port 3#, port 4#, port 5#, port 6#, and port 7#. If it is known that the port identifiers of the ports included in each port group are consecutive, the starting port identifier of port group A is port 0#. If the second configuration information configures the number of ports included in group A to be 3, then the ports included in port group A are: port 0#, port 1#, and port 2#.

[0151] In some embodiments, if the port identifiers included in the port group corresponding to each port group identifier are non-consecutive, the port identifiers in each port group are directly indicated by the second configuration information.

[0152] Exemplarily, the reference signal resource has eight ports, namely: port 0#, port 1#, port 2#, port 3#, port 4#, port 5#, port 6#, and port 7#. If it is known that the port identifiers of the ports included in each port group are non-consecutive, the second configuration information can indicate that the ports of port group A are: port 2#, port 4#, and port 5# (or other combinations, etc.).

[0153] Thus, the correspondence between the port identifier and the port group identifier in the port information and how the correspondence between the two is determined can be clarified.

[0154] In some embodiments, terminal 101 needs to measure a reference signal resource having multiple ports to obtain a quality parameter.

[0155] Optionally, the terminal 101 measures each port of the multi-port reference signal resource separately to obtain a corresponding quality parameter, where the quality parameter may be, for example, L1-RSRP and / or L1-SINR.

[0156] For example, if the ports corresponding to reference signal resource A are port 1# and port 2#, the terminal needs to measure port 1# and / or port 2# to obtain the quality parameter corresponding to port 1# of the reference signal resource and the quality parameter corresponding to port 2# of the reference signal resource, respectively.

[0157] It is understandable that if terminal 101 is in a far-field communication scenario, since the beam directed to terminal 101 in the far-field communication scenario is a two-dimensional directional beam directed toward terminal 101, the time and phase of the beams transmitted by each port of the reference signal resource arriving at the receiving antenna array of terminal 101 are equally spaced. Therefore, in this case, a corresponding measurement report can be obtained by measuring the quality parameters corresponding to one (or some) of the multiple ports. This can reduce the signaling overhead generated during the measurement process.

[0158] It can be understood that, taking the measurement of the L1-SINR of a multi-port reference signal resource as an example, by measuring the L1-SINR of the multi-port reference signal resource and sending the corresponding measurement report in combination with the port information to the network device 102, the network device 102 can obtain the L1-SINR corresponding to each port through the measurement report, and then select the port that meets the requirements (for example, the strongest L1-SINR) to configure the terminal 101, so that the terminal 101 and the network device 102 can communicate and transmit based on the QCL assumption corresponding to the port, thereby ensuring the communication quality.

[0159] In some embodiments, the form of the measurement report may include: a non-group based beam report and / or a group-based beam report, wherein the group-based beam report includes at least one beam group.

[0160] Taking the measurement report based on the beam group as an example, the beam group needs to meet certain conditions so that the network device 102 can determine the measurement results corresponding to different ports of the reference signal resource with multiple ports based on the measurement report of the beam group.

[0161] Optionally, the beam groups meet the following condition: each beam group includes at least two different identifier combinations. In other words, the beam group needs to include at least two different identifier combinations to reflect different ports or port groups of reference signal resources of multiple ports, and thus reflect the measurement results corresponding to different ports or port groups.

[0162] Exemplarily, each beam group includes at least two different identification combinations, including at least one of the following -1) to -6):

[0163] 1) At least two reference signal resource identifiers in a beam group are different, and at least two port group identifiers in the beam group are different. For example, a beam group contains two multi-port reference signal resources, reference signal resource #A and reference signal resource #B. Reference signal resource #A has two ports and its corresponding port group identifier is #1. Reference signal resource #B has two ports and its corresponding port group identifier is #2. Obviously, port group identifier #1 and port group identifier #2 are two different identifiers.

[0164] 2) At least two reference signal resource identifiers in the beam group are different, and at least two port identifiers in the beam group are different. For example, the beam group contains two multi-port reference signal resources, reference signal resource #A and reference signal resource #B. Reference signal resource #A has two ports, identified as #A1 and #A2, and reference signal resource #B has two ports, identified as #B1 and #B2. Obviously, these port identifiers are different.

[0165] 3) At least two reference signal resource identifiers in the beam group are identical, and the port identifiers of these two reference signal resources are different. Alternatively, the beam group contains one reference signal resource identifier and two port identifiers. For example, the beam group contains two multi-port reference signal resources, but both have the same identifier, A. Alternatively, the beam group contains one multi-port reference signal resource, A, where one port of this reference signal resource is identified as #A1 and the other as #A2. Clearly, these port identifiers are different.

[0166] 4) At least two reference signal resource identifiers in the beam group are identical, and the port group identifiers of these two reference signal resources are different. Alternatively, the beam group contains one reference signal resource identifier and two port identifiers. For example, there are two multi-port reference signal resources in the beam group, but both have the same identifier, A. Alternatively, there is one multi-port reference signal resource A in the beam group, where one port group identifier of this reference signal resource is #1 and the other port group identifier is #2. Clearly, these identifier groups are different.

[0167] -5) At least two port identifiers in the beam group are different. For example, the reference signal resource identifiers in the beam group can be one or more, and if at least two port identifiers are different, it is also considered that the beam group includes at least two different identifier combinations.

[0168] -6) At least two port group identifiers in the beam group are different. For example, the reference signal resource identifiers in the beam group can be one or more, and if at least two port group identifiers are different, it is also considered that the beam group includes at least two different identifier combinations.

[0169] It is understandable that for cases -5) and -6), since different reference signal resources correspond to the same port with the same beam direction, and the same port cannot point to different beam directions at the same time, in some cases, it is not necessary to consider whether the reference signal resource identifiers are the same, and it is sufficient to directly consider whether the port identifiers or port group identifiers included in the beam group are the same.

[0170] Through the above embodiment, the network device 102 can determine the measurement result corresponding to each port of the multi-port reference signal resource based on the measurement report reported by the terminal 101, and then configure a port for communication transmission for the terminal 101. For example, the port with the strongest signal strength can be determined based on the quality parameter measurement result corresponding to each port of each multi-port reference signal resource, and the port can be configured to the terminal 101 for subsequent communication transmission.

[0171] Step S2103, the network device 102 sends TCI configuration information to the terminal 101.

[0172] In some embodiments, the terminal 101 receives transmission configuration indicator (TCI) configuration information sent by the network device 102 .

[0173] In some embodiments, the TCI configuration information is used to configure a Transmission Configuration Indicator State (TCI state), wherein the TCI state is used to indicate a reference signal resource identifier and port information corresponding to a quasi co-location (QCL).

[0174] It is understandable that when the reference signal resource is configured as a multi-port, the measurement results corresponding to each port may be different (for example, in the near-field communication scenario, the signal strength of the reference signal corresponding to each port reaching the terminal is different). If the TCI status still only indicates the reference signal resource identifier corresponding to the QCL, it is impossible to determine the reference signal resource corresponding to the QCL (that is, it is impossible to determine which port of the multi-port reference signal resource the reference signal resource corresponding to the QCL comes from). Therefore, for multi-port reference signal resources, it is necessary to clearly indicate the port information corresponding to the reference signal resource through the TCI status.

[0175] In some embodiments, the port information indicated by the TCI status may be the port information determined by the network device 102 based on the measurement report in step S2102, for example, the port information with the best determined reference signal quality parameter.

[0176] It is understandable that each QCL type corresponds to a reference signal resource identifier, and the traditional TCI state can correspond to the following four QCL types:

[0177] -Type A: Type A can represent Doppler shift, Doppler spread, average delay, and delay spread.

[0178] -Type B: Type B can represent Doppler shift and Doppler spread.

[0179] -Type C: Type C can indicate Doppler shift and average delay.

[0180] -Type D: Type D may indicate a spatial Rx parameter.

[0181] It should be noted that each of the four QCL types mentioned above can correspond to a reference signal resource identifier, but none of them corresponds to port information. Therefore, the TCI status is required to indicate the reference signal resource and port information corresponding to the QCL. The reference signal resource identifier and port information corresponding to the QCL indicated by the TCI status can be implemented in the following two ways:

[0182] -a) This is achieved by reusing existing QCL types.

[0183] -b) Implemented by adding a new QCL type.

[0184] For case -a), since each existing QCL type can correspond to a reference signal resource identifier, the TCI state only needs to reuse the existing QCL type and indicate the port information at the same time.

[0185] Exemplarily, the TCI state can indicate the reference signal resource identifier and port information corresponding to the QCL in the following manner: the TCI state indicates the reference signal resource identifier corresponding to the first type of QCL and the port information corresponding to the first type of QCL, wherein the first type of QCL is a Type D QCL (i.e., a QCL representing spatial reception parameters).

[0186] Based on this, by reusing existing QCL types, the resource overhead caused by new signaling can be avoided.

[0187] For case -b), a new QCL type can be added to represent the port information, and the resource identifier of the existing QCL type and the port information corresponding to the new QCL type can be simultaneously indicated through the TCI status.

[0188] Exemplarily, the TCI state can indicate the reference signal resource identifier and port information corresponding to the QCL in the following manner: the TCI state indicates the reference signal resource identifier corresponding to the first type (Type D) QCL and the port information corresponding to the second type QCL, wherein the first type of QCL is a Type D QCL, and the second type of QCL is different from the first type of QCL.

[0189] Optionally, the reference signal resource identifier corresponds to the second type of QCL.

[0190] It can be understood that the second type of QCL is a newly added QCL type used to represent port information.

[0191] In some embodiments, the second type QCL represents at least one of: a first distance; a port identifier; a port group identifier.

[0192] Optionally, the first distance is determined based on port information.

[0193] It can be understood that in a scenario where communication transmissions are performed on the same port (i.e., based on the same direction), there may be multiple terminals, such as terminal #1, terminal 2#, terminal #3, and so on. However, in the same direction, the distances from the port to different terminals may be different. For example, the distance from the port to terminal #1 is a, the distance from the port to terminal #2 is b, and the distance from the port to terminal #3 is c, where the relationship between a, b, and c is: a < b < c. Without distance indication, when the network device sends a beam in the direction of terminal #3, since terminal #1 and terminal #2 are closer to the network device than terminal #3 in this direction, the network device may interfere with terminal #1 and terminal #2 during the process of sending the beam to terminal #3. Therefore, by indicating the distance, the network device can directly send the beam to terminal #3 in this direction, thereby reducing the interference caused to terminal #1 and terminal #2.

[0194] In some embodiments, the port identifier may be, for example, an anchor port identifier.

[0195] In some embodiments, the port group identifier may be, for example, an anchor port group identifier.

[0196] It should be noted that if the communication scenario is a far - field communication scenario, based on the description of the far - field communication scenario in the above - mentioned related embodiments, since in the far - field communication scenario, the directions and the distances from each port of the multi - port reference signal resource to the terminal are the same. Therefore, in a far - field communication scenario, the TCI state may not need to indicate port information.

[0197] In some embodiments, terms such as "certain", "preseted", "preset", "set", "indicated", "a certain", "any", "first", etc. can be replaced with each other. "Specific A", "Preseted A", "Preset A", "Set A", "Indicated A", "A certain A", "Any A", "First A" can be interpreted as A pre - specified in a protocol, etc., or can be interpreted as A obtained through setting, configuration, or indication, etc., or can be interpreted as specific A, a certain A, any A, or first A, etc., but is not limited thereto.

[0283] Figure 5 is an interactive diagram of a resource configuration method according to an embodiment of the present disclosure. As shown in Figure 5, the embodiment of the present disclosure relates to a resource configuration method, which includes:

[0284] Step S5101, send TCI configuration information.

[0285] In some embodiments, the TCI configuration information is used to configure the TCI state, and the TCI state is used to indicate the reference signal resource identifier and port information corresponding to the QCL.

[0286] The optional implementation of step S5101 can refer to the optional implementation of step S2101, step S2102, step S2103 in Figure 2, and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0287] In some embodiments, the above method may also include the methods described in the above embodiments such as the communication system side, the terminal side, and the network device side, which will not be repeated here.

[0288] In some embodiments, the embodiments of the present disclosure also propose a communication method, in which the reference signal resources used for beam measurement can be configured as multiple ports, and when the beam measurement results are reported, not only the reference signal resource identifier is reported, but also the port index or port group index (used to indicate the distance from each port or port group to the terminal) is reported, so that the base station can more accurately know which port can provide the best performance for transmission to the terminal.

[0289] In some embodiments, the terminal receives TCI state configuration information, where the TCI state configuration information includes at least one TCI state, and the at least one TCI state indicates a reference signal resource identifier and a port identifier or a port group identifier corresponding to the QCL information.

[0290] It is understandable that the traditional TCI state can correspond to the following four QCL types, each of which corresponds to a reference signal resource identifier:

[0291] -Type A: Type A can represent Doppler shift, Doppler spread, average delay, and delay spread.

[0292] -Type B: Type B can represent Doppler shift and Doppler spread.

[0293] -Type C: Type C can indicate Doppler shift and average delay.

[0294] -Type D: Type D may indicate a spatial Rx parameter.

[0295] In some embodiments, the port identifier / port group identifier proposed in the present invention may correspond to the traditional Type D, i.e., QCL Type D corresponds to a reference signal resource identifier and a port or port group identifier; or a new Type E may be introduced. Type E is defined as indicating: distance, port identifier, or port group identifier.

[0296] It is understandable that a Type E is added to indicate a port or port group identifier, and the reference signal resource corresponding to the port or port group identifier is the reference signal resource indicated by Type D.

[0297] In some embodiments, the port / port group identifier is optional in the TCI state configuration information, for example, it only appears for near-field UEs but not for far-field UEs.

[0298] In some embodiments, the terminal receives first configuration information, the first configuration information including reference signal resource configuration information, and the reference signal resource corresponds to multiple ports; the terminal performs measurement based on the reference signal resource configuration information, obtains a measurement report, and sends the measurement report to the network device, wherein the measurement report includes at least one of a reference signal resource identifier, L1-RSRP / L1-SINR, a port identifier, and a port group identifier.

[0299] In some embodiments, when the measurement report includes a port group identifier, a method for determining a correspondence between the port group identifier and the port identifier is as follows:

[0300] Determined based on default rules and / or based on configuration information indication.

[0301] Optionally, the determination is based on a default rule, for example: each port group includes N consecutive ports; each port group includes N ports that are equally spaced; or the ports included in the port group are specified by a protocol.

[0302] For example, if determined by default rules, reference signal resources or / channels may not occupy all ports in each port group. For example, a port group includes ports 0, 1, and 2, while reference signals and channels may only occupy port 0, or port 0 and port 1.

[0303] In some embodiments, based on the configuration information indication, for example: if the included ports are continuous: the number of ports included in each port group is configured, where the starting port index is determined by default; if not continuous, the port identifier (index) identifier of the port included in each port group is directly indicated.

[0304] In some embodiments, the measurement report includes a group based beam report or a non-group based beam report.

[0305] Optionally, the measurement report for a beam group includes at least one beam group, and each beam group includes at least two different identification combinations, for example:

[0306] -1) The identifier combination includes a reference signal resource identifier and a port identifier or a port group identifier. If any one of them is different, the identifier combination is different.

[0307] -2) The reference signal resource identifiers corresponding to the identifier combinations included in the beam group can be the same.

[0308] -3) The port or port group identifiers corresponding to the identifier combinations contained in the beam group cannot be the same.

[0309] It should be noted that, for -3), since the beam directions of the same port corresponding to different reference signal resources are the same, and the same port cannot point to different beam directions at the same time, the port or port group identifiers corresponding to the required identification combination cannot be the same.

[0310] In some embodiments, the reference signal resource includes a CSI-RS, or an SSB.

[0311] In some embodiments, the TCI state configuration information is RRC, MAC CE and / or DCI.

[0312] Based on this, the present disclosure proposes that the TCI status not only indicates the reference signal resource identifier, but also indicates the port / port group index to report the distance from the port / port group to the terminal, so that the base station can select the appropriate port / port group for transmission to the terminal.

[0313] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0314] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits.

All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

In addition, 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), a deep learning processing unit (DPU), etc.
