AI Technical Summary
In new air communication, high-frequency channels attenuate rapidly, resulting in insufficient coverage. Existing technologies require a large amount of resources for beam measurement of non-serving cells, which increases the complexity of terminal measurement and resource overhead.
The second value of the non-serving cell is determined based on the first value of the serving cell, and a report is sent to the network equipment. This reduces the overhead of beam measurement reference signal resources and the complexity of terminal measurement for the non-serving cell. An AI model is used for beam prediction.
It effectively reduces the overhead of beam measurement resources and the complexity of terminal measurement in non-serving cells, thereby improving communication efficiency.

[0078] During beam management, the base station configures a set of reference signal resources for beam measurement. The terminal measures the reference signal resources in this set and then reports the identifiers (IDs) of the X strongest reference signal resources, along with their corresponding Layer 1 reference signal received power (L1-RSRP) and / or Layer 1 signal to interference plus noise ratio (L1-SINR). The problem with traditional methods is that the base station's configured set contains M reference signal resources, each corresponding to a different transmitted beam. Therefore, for each reference signal resource, the terminal needs to use all received beams to measure it, obtain the beam measurement quality for each received beam, and determine the best beam measurement quality. Thus, the number of beam pairs the terminal needs to measure is M*N, where M is the number of transmitted beams from the base station and N is the number of received beams from the terminal.
[0079] The following explains the specific processes by which beam information is output by artificial intelligence (AI) models and obtained by traditional methods.
[0080] The principle of beam prediction based on AI models is as follows:
[0081] For spatial prediction: The L1-RSRP of the terminal measurement set B (which may also include beam or beam pair IDs) is input into the AI model to predict the L1-RSRP of set A (set A) or the optimal beam ID of set A. The relationship between set B and set A includes the following two types:
[0082] First, set B is a subset of set A. For example, if set A contains 32 reference signal resources (each reference signal resource corresponds to a beam direction), then set B contains N of those reference signal resources, such as N=8. The above only considers the transmit beams. If beam pairs are considered, the terminal's receive beams also need to be taken into account. For example, if there are 32 transmit beams and the terminal has 4 receive beams, then set A would have 32*4 beam pairs; set B could have 32 beam pairs, 16 beam pairs, etc. Here, * stands for multiplication.
[0083] Second, set B is a wide beam, and set A is a narrow beam. For example, set A contains 32 reference signal resources (each reference signal resource corresponds to a beam direction, and the 32 reference signals cover a 120-degree direction). Set B contains another N reference signal resources, for example, N=8, and these N reference signals also cover a 120-degree direction. That is, the beam direction of each reference signal in set B covers the beam directions of multiple reference signal resources in set A. This can be understood as the 32 / N reference signal resources in set A and the same reference signal resource in set B having a quasi-co-location (QCL) type (Type D) relationship.
[0084] If monitoring the performance of the AI model is not required, assuming that the AI model has been pre-trained, the network device only needs to periodically send the reference signal of set B (e.g., in the first cycle). Then, the terminal measures the L1-RSRP of the reference signal in set B and inputs it into the AI model. The model can then output the L1-RSRP of all beams or beam pairs in set A, or output the IDs of the K strongest reference signals or beam pairs among the 32 reference signals in set A.
[0085] If monitoring AI model performance is required, in addition to sending set B, the network device is also required to periodically send reference signals for set A (e.g., the second period, which is longer than the first period; whether it's a multiple of the first period or by how much longer is not restricted here). The terminal then only measures the result of set B and inputs it into the AI model to obtain the predicted beam information, which is then reported to the network device. Simultaneously, the L1-RSRP of all reference signals in set A is measured, and the beam information is obtained and reported to the network device. Of course, if set B is a subset of set A, it's equivalent to the terminal only needing to measure all beams or beam pairs in set A.
[0086] For time-domain prediction, the terminal measures the L1-RSRP of historical time set B and inputs it into the AI model to predict the L1-RSRP or optimal beam ID of future time set A. Besides the two relationships mentioned above, there is another possibility: set B and set A are the same.
[0087] If beam prediction is based on an AI model, then the reference signal for future moments does not need to be sent; that is, beam information can be obtained based on the output of the AI model and reported to the network equipment.
[0088] If beam prediction is performed using methods from related technologies, reference signals for future timeframes also need to be transmitted for performance monitoring. The terminal measures the reference signals for future timeframes and obtains beam information, which is then reported to the base station. Therefore, during model performance monitoring, for co-spatial beam prediction, network devices need to periodically transmit the transmitted beams in set B and set A, and the terminal needs to measure all beams or beam pairs in set B and set A.
[0089] However, currently, AI-based beam prediction is only supported within the same serving cell. For example, if a serving cell contains a total of 32 transmit beams, spatial beam prediction involves the terminal measuring only 8 transmit beams to predict the prediction results for all transmit beams. Temporal beam prediction involves the terminal measuring at least a portion of the 32 transmit beams from historical times to predict the prediction results for all transmit beams in the future. However, in beam-based communication systems, when a terminal is in an area where multiple cells overlap in coverage, the base station will also configure the terminal to perform beam measurements on neighboring cells to obtain their beam measurement results. This is involved in inter-cell beam management and L1-L2 triggered mobility projects. For example, the reference signal resources for neighboring cell measurements include the Synchronization Signal Block (SSB) and the Channel State Information Reference Signal (CSI-RS).
[0090] Therefore, this disclosure provides a communication method that determines a second value corresponding to one or more non-serving cells based on a first value corresponding to a serving cell, and sends a report to a network device containing the second value. This enables the determination of the second value of a non-serving cell using the first value of the serving cell, thereby reducing resource overhead associated with non-serving cells, such as reducing beam measurement reference signal resource overhead for non-serving cells, reducing the number of beams or beam pairs, and reducing the complexity of terminal measurements.
[0091] Figure 1 is a schematic diagram of a communication system architecture according to an embodiment of the present disclosure.
[0092] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.
[0093] In some embodiments, terminal 101 includes, but is not limited to, 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.
[0094] In some embodiments, network device 102 may include at least one of access network device and core network device.
[0095] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.
[0096] 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.
[0097] 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.

[0102] 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:
[0103] In step S2101, terminal 101 sends second information to network device 102.
[0104] In some embodiments, network device 102 receives second information sent by terminal 101.
[0105] In some embodiments, the second information is used to instruct the terminal to support determining a second value corresponding to one or more non-serving cells based on a first value corresponding to a serving cell. Alternatively, the second information may be used to instruct the terminal to have the capability to determine a second value corresponding to one or more non-serving cells based on a first value corresponding to a serving cell. For example, the terminal may deploy an AI model (the AI model can be replaced by an AI function, or an ML function, or an ML model; this embodiment uses an AI model as an example for illustration, but is not limited thereto), input the first value corresponding to the serving cell into the AI model, and the AI model outputs the second value of the non-serving cell. Therefore, it can be considered that the terminal supports determining a second value corresponding to one or more non-serving cells based on the first value corresponding to the serving cell, or that the terminal has the capability to determine a second value corresponding to one or more non-serving cells based on the first value corresponding to the serving cell.
[0106] In some embodiments, the first value corresponding to a serving cell can be a first value corresponding to one serving cell or a first value corresponding to multiple serving cells. For example, if there are multiple first values corresponding to multiple serving cells, and each serving cell corresponds to one or more non-serving cells, the terminal can determine the second value of the first or multiple non-serving cells corresponding to that serving cell based on the first value corresponding to each serving cell.
[0107] In some embodiments, the serving cell may also be referred to as the terminal's serving cell or the cell where the terminal is currently residing.
[0108] In some embodiments, a non-serving cell may also be referred to as a neighboring cell of the serving cell.
[0109] In some embodiments, this disclosure refers to a non-serving cell corresponding to a serving cell as a first non-serving cell. The terminal may support determining a second value corresponding to a second non-serving cell based on a first value corresponding to the serving cell. The second non-serving cell may be part or all of the first non-serving cells. For example, the terminal has M non-serving cells corresponding to its serving cell, meaning there are M first non-serving cells. The terminal may support determining a second value corresponding to N of the M first non-serving cells based on the first value corresponding to the serving cell. This disclosure refers to these N first non-serving cells as second non-serving cells, where M is greater than or equal to N, meaning the second non-serving cells are part or all of the first non-serving cells. Here, M and N are integers, where M is a positive integer and N is a positive or equal integer.
[0110] In some embodiments, the first value may be a measured value, or a measurement result, a first result, etc., which is not limited in this disclosure. The measured value or measurement result can be understood as a value or result obtained by actually measuring the reference signal. The second value may be a predicted value, or a prediction result, a second result, etc., which is not limited in this disclosure. The predicted value or prediction result can be understood as a predicted value or result, for example, a value or result output by an AI model, i.e., a value or result not obtained by actual measurement. Exemplarily, the second information can be used to instruct the terminal to support measurements based on the serving cell and to determine predicted values for non-serving cells.
[0111] In some embodiments, the first value includes quality information corresponding to the first reference signal resource. The first reference signal resource refers to each reference signal resource in the first reference signal resource set corresponding to the serving cell. That is, the first value includes the quality information of each reference signal resource in the reference signal resource set corresponding to the serving cell. In this disclosure, the reference signal resource set corresponding to the terminal's serving cell is referred to as the first reference signal resource set, and each reference signal resource in the first reference signal resource set is referred to as the first reference signal resource. For example, the terminal can perform actual measurements on the reference signals on the first reference signal resources to obtain the quality information corresponding to the first reference signal resources, and the first value may include this quality information. The quality information may include, but is not limited to, at least one of the following: Layer 1 reference signal received power (L1-RSRP); Layer 1 signal to interference plus noise ratio (L1-SINR); Layer 3 reference signal received power (L3-RSRP); Layer 3 reference signal received quality (L3-RSRQ); Layer 3 received signal strength indication (L3-RSSI); and Channel State Information (CSI). CSI may include, but is not limited to, Precoding Matrix Indicator (PMI), Rank Indication (RI), and Channel Quality Indicator (CQI).
[0112] Optionally, the first value can be a first beam value, a beam measurement value, a first beam result, or a beam measurement result, etc. For example, when the first value includes at least one of L1-RSRP and L1-SINR corresponding to the first reference signal resource, the first value can be a first beam value, etc.
[0113] Optionally, the first value can be a first Radio Resource Management (RRM) value, an RRM measurement value, a first RRM result, or an RRM measurement result, etc. For example, when the first value includes at least one of L3-RSRP, L3-RSRQ, and L3-RSSI corresponding to the first reference signal resource, the first value can be a first RRM value, etc.
[0114] Optionally, the first value can be a first layer 3 value, a layer 3 measurement value, a first layer 3 result, or a layer 3 measurement result, etc. For example, when the first value includes at least one of L3-RSRP, L3-RSRQ, and L3-RSSI corresponding to the first reference signal resource, the first value can be a first layer 3 result.
[0115] Optionally, the first value can be a first CSI value, a CSI measurement value, a first CSI result, or a CSI measurement result, etc. For example, when the first value includes the CSI corresponding to the first reference signal resource, the first value can be the first CSI value, etc.
[0116] In some embodiments, the second value includes at least one of the following: quality information corresponding to the second reference signal resource; identifiers of the K reference signal resources with the best quality information in the second reference signal resource set; and identifiers of the second non-serving cells corresponding to the Q reference signal resources with the best quality information in the second reference signal resource set, where K and Q are positive integers. The second reference signal resource is at least one reference signal resource in the second reference signal resource set, and the second reference signal resource set is the reference signal resource set corresponding to each of the at least one second non-serving cells. This disclosure refers to the reference signal resource set corresponding to each of the at least one second non-serving cells as the second reference signal resource set, and the at least one reference signal resource in the second reference signal resource set as the second reference signal resource. The quality information can be referred to in the above embodiments, and will not be repeated here.
[0117] Optionally, the terminal may determine the quality information (i.e. the quality information corresponding to the second reference signal resource) of at least one reference signal resource in the reference signal resource set corresponding to each of the at least one second non-serving cells, based on the first value corresponding to the serving cell.
[0118] For example, there are M first non-serving cells, of which N are second non-serving cells. For details, please refer to the above embodiment, which will not be repeated here. Assume that at least one second non-serving cell is X second non-serving cells, where X is greater than 1 and less than or equal to N. Each of the X second non-serving cells corresponds to a set of reference signal resources, i.e., X sets of reference signal resources. Each set of reference signal resources includes at least one reference signal resource, i.e., at least X reference signal resources. Therefore, at least one reference signal resource in the set of reference signal resources corresponding to each of the at least one second non-serving cell is one of these at least X reference signal resources. The second value determined by the terminal may include the quality information of these at least X reference signal resources.
[0119] Optionally, the terminal can determine, based on the first value corresponding to the serving cell, the identifiers of the K reference signal resources with the best quality information in the reference signal resource set corresponding to each of the at least one second non-serving cell (i.e., the identifiers of the K reference signal resources with the best quality information in the second reference signal resource set). The K reference signal resources with the best quality information can be understood as the reference signal resources corresponding to the K largest quality information values, sorted from largest to smallest.
[0120] For example, there are M first non-serving cells, of which N are second non-serving cells. Assume at least one second non-serving cell is X second non-serving cells, where X is greater than 1 and less than or equal to N. Each of the X second non-serving cells corresponds to a set of reference signal resources, i.e., X sets of reference signal resources. For details, please refer to the above embodiment; further explanation is unnecessary.
[0121] For example, each of the X sets of reference signal resources contains K reference signal resources with optimal quality information. That is, there are X*K reference signal resources with optimal quality information, and the second value determined by the terminal may include the identifiers of these X*K reference signal resources with optimal quality information. Of course, the number of reference signal resources with optimal quality information may differ in different sets of reference signal resources. For example, reference signal resource set 1 may include K1 reference signal resources with optimal quality information, reference signal resource set 2 may include K2 reference signal resources with optimal quality information, and so on, and reference signal resource set X may include K... X The best quality reference signal resource. Then the second value determined by the terminal can include K1 + K2 + ... + K X The identifier of the best reference signal resource for quality information.
[0122] For example, there are K reference signal resources with optimal quality information in the X sets of reference signal resources. That is, among all the reference signal resources in the X sets of reference signal resources, there are K reference signal resources with optimal quality information, and the second value determined by the terminal may include the identifier of the K reference signal resources with optimal quality information. Among the K reference signal resources with optimal quality information, each reference signal resource may correspond to a different set of reference signal resources, or some reference signal resources may correspond to the same set of reference signal resources. For example, reference signal resource set 1 may have one reference signal resource among the K reference signal resources with optimal quality information, reference signal resource set 2 may have two reference signal resources among the K reference signal resources with optimal quality information, and reference signal resource set 3 may have no reference signal resources among the K reference signal resources with optimal quality information. This disclosure does not limit this.
[0123] For example, X and K can be the same value, and each of the X sets of reference signal resources can include one reference signal resource with the best quality information, so there are a total of X reference signal resources with the best quality information in the X sets of reference signal resources. The second value determined by the terminal can include the identifiers of the X reference signal resources with the best quality information.
[0124] Optionally, the terminal can determine, based on the first value corresponding to the serving cell, the identifiers of the Q reference signal resources with the best quality information in the reference signal resource set corresponding to each of the at least one second non-serving cell (i.e., the identifiers of the Q reference signal resources with the best quality information in the second reference signal resource set). For example, there are M first non-serving cells, of which there are N second non-serving cells. For details, please refer to the above embodiments, which will not be repeated here. Assume that there are X second non-serving cells, where X is greater than 1 and less than or equal to N. Each of the X second non-serving cells corresponds to a reference signal resource set, i.e., X reference signal resource sets. There are a total of Q reference signal resources with the best quality information in the X reference signal resource sets, meaning that among all the reference signal resources in the X reference signal resource sets, there are Q reference signal resources with the best quality information. Among the Q best-quality reference signal resources, each reference signal resource may correspond to a different set of reference signal resources, i.e., different second non-serving cells, or some reference signal resources may correspond to the same set of reference signal resources, i.e., the same second non-serving cell. That is, the number of second non-serving cells corresponding to each of the Q best-quality reference signal resources may be less than or equal to Q. The second value determined by the terminal may include the identifiers of these less than or equal to Q second non-serving cells. The sizes of Q and K can be the same or different; this disclosure does not impose any limitation.
[0125] Optionally, the second value can be a second beam value, a beam prediction value, a second beam result, or a beam prediction result, etc. For example, when the second value includes at least one of L1-RSRP and L1-SINR corresponding to the second reference signal resource, the second value can be called a second beam value, etc.
[0126] Optionally, the second value can be a second Radio Resource Management (RRM) value, an RRM prediction value, a second RRM result, or an RRM prediction result, etc. For example, when the second value includes at least one of L3-RSRP, L3-RSRQ, and L3-RSSI corresponding to the second reference signal resource, the second value can be a second RRM value, etc.
[0127] Optionally, the second value can be a second layer 3 value, a layer 3 prediction value, a second layer 3 result, or a layer 3 prediction result, etc. For example, when the second value includes at least one of L3-RSRP, L3-RSRQ, and L3-RSSI corresponding to the second reference signal resource, the second value can be a second layer 3 result.
[0128] Optionally, the second value can be a second CSI value, a CSI prediction value, a second CSI result, or a CSI prediction result, etc. For example, when the second value includes the CSI corresponding to the second reference signal resource, the second value can be the second CSI value, etc.
[0129] In some embodiments, the terminal determines the second value corresponding to the second non-serving cell based on the first value of the serving cell, which may include the following exemplary cases:
[0130] Scenario 1: The output of the AI model may include at least one of the following quality information for each reference signal resource set corresponding to each second non-serving cell: L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, CSI (PMI, RI, CQI, etc.). Based on this output, the terminal can determine the reference signal resource with the best quality information and the second non-serving cell corresponding to the reference signal resource with the best quality information. In this disclosure, the reference signal resource with the best quality information is referred to as the strongest reference signal resource, and the second non-serving cell corresponding to the reference signal resource with the best quality information is referred to as the strongest second non-serving cell. The terminal can determine the strongest second non-serving cell identifier and the strongest reference signal resource identifier through all the quality information output by the model. Therefore, regardless of whether the network device requires the terminal to report the strongest second non-serving cell identifier, the strongest reference signal resource identifier, or quality information, the terminal can obtain them.
[0131] Scenario 2: The AI model's output may not include quality information. For example, it might include the probability that each second non-serving cell is the strongest second non-serving cell. In this case, the terminal, based on the model's output, can only obtain the identifier of the strongest second non-serving cell, i.e., the second non-serving cell with the highest probability. It cannot obtain the identifier of the strongest reference signal resource or quality information.
[0132] Scenario 3: The AI model's output may not include quality information. For example, it might include the probability that the quality information for each reference signal resource in each second non-serving cell is the highest. In this case, the terminal, based on the model's output, can only obtain the identifier of the strongest reference signal resource, and further, the identifier of the strongest second non-serving cell corresponding to the strongest reference signal resource. It cannot obtain quality information.
[0133] It is understood that the above situations are all exemplary and this disclosure does not limit them.
[0134] In some embodiments, the reference signal resources (including but not limited to the first reference signal resources and the second reference signal resources) may be SSB or CSI-RS.
[0135] In some embodiments, the network device receives second information, and based on the second information, it can determine that the terminal supports determining a second value corresponding to one or more non-serving cells based on a first value corresponding to the serving cell. This allows the network device to reduce or eliminate the need to configure resources for measuring non-serving cells for the terminal; for example, resources may be reference signal resources, signaling resources, etc. Measuring non-serving cells may include, but is not limited to, beam measurement, L3 measurement, RRM measurement, CSI measurement, etc., of the serving cell.
[0136] In some embodiments, the second information may be capability information, and this disclosure does not limit the name of the second information.
[0137] It is understood that step S2101 is optional. For example, the network device may default to the terminal supporting the determination of one or more second values corresponding to non-serving cells based on the first value corresponding to the serving cell. Alternatively, the protocol may specify that the terminal supports the determination of one or more second values corresponding to non-serving cells based on the first value corresponding to the serving cell. Alternatively, in some embodiments, second information may be sent; in other embodiments, since the second information has already been sent, it may not be sent again. That is, the terminal may send the second information once, and then not send it again in subsequent processes of determining one or more second values corresponding to non-serving cells based on the first value corresponding to the serving cell. In any one or more of the above situations, step S2101 may be omitted. However, this disclosure only provides examples of omitting step S2101 and is not limited to this.
[0138] In step S2102, network device 102 sends fourth information to terminal 101.
[0139] In some embodiments, terminal 101 receives fourth information sent by network device 102.
[0140] In some embodiments, the fourth information is used to indicate the first non-serving cell. For example, the network device may indicate to the terminal which non-serving cells (i.e., the first non-serving cells) correspond to the serving cell, thereby facilitating the terminal to determine the second non-serving cell from the first non-serving cells, that is, to determine which first non-serving cells the terminal supports based on the first value of the serving cell and to determine its second value.
[0141] In some embodiments, the fourth information may include at least one of the following: the number of the first non-serving cell in the list; the physical cell identifier of the first non-serving cell; and the globally unique identifier of the first non-serving cell.
[0142] Optionally, the fourth information may include the number of the first non-serving cell in the list. For example, the coverage area of a network device may be divided into one or more cells. The network device may store a table containing the first non-serving cells corresponding to one or more cells within the network device's coverage area when they become the serving cells of a terminal. That is, the table includes the correspondence between cell identifiers and first non-serving cell identifiers within the network device's coverage area. The network device can determine the number of the first non-serving cell from the table based on the terminal's serving cell. For example, the table stored by the network device may be Table 1. As shown in Table 1, assuming the network device's coverage area can be divided into three cells, identified as cell #1, cell #2, and cell #3, when cell #1 becomes the serving cell of the terminal, the first non-serving cells include first non-serving cell #1-1 and first non-serving cell #1-2; when cell #2 becomes the serving cell of the terminal, the first non-serving cells include first non-serving cell #2-1 and first non-serving cell #2-2; and when cell #3 becomes the serving cell of the terminal, the first non-serving cells are first non-serving cell #3-1 and first non-serving cell #3-2. If the serving cell of the terminal is cell #1, the network device can send the numbers "#1-1" and "#1-2" to the terminal via the fourth information. If the serving cell of the terminal is cell #2, the network device can send the numbers "#2-1" and "#2-2" to the terminal via the fourth information. If the serving cell of the terminal is cell #3, the network device can send the numbers "#3-1" and "#3-2" to the terminal via the fourth information. Upon receiving the fourth information, the terminal can determine which cell the first non-serving cell is based on its number. For example, the terminal can store the correspondence between the number and the identifier of the first non-serving cell, thereby determining the identifier of the first non-serving cell based on the number, and further determining the PCI of the first non-serving cell. The identifier of the first non-serving cell can be a Physical Cell Identifier (PCI) or a globally unique cell ID; this disclosure does not limit the specific identifier.
[0143] Table 1
[0144] Optionally, the fourth information may include the PCI of the first non-serving cell.
[0145] Optionally, the fourth information may include the cell global ID of the first non-serving cell.
[0146] In some embodiments, the name of the fourth information is not limited, and it may be, for example, "instruction information".
[0147] It is understandable that step S2102 is optional. For example, if the terminal can determine which first non-serving cells correspond to the serving cell on its own, without requiring the network device to indicate this via the fourth information, then step S2102 can be omitted. Alternatively, one purpose of the network device indicating which first non-serving cells are present is to facilitate the terminal's determination of the second non-serving cells and to indicate the second non-serving cells to the network device. If the network device can determine the second non-serving cell corresponding to the terminal's serving cell on its own—for example, if the protocol specifies the second non-serving cell corresponding to the terminal's serving cell—then the terminal does not need to indicate the second non-serving cell to the network device, and consequently, the network device does not need to indicate the first serving cell corresponding to the serving cell to the terminal. In this case, step S2102 can be omitted.
[0148] In step S2103, terminal 101 sends third information to network device 102.
[0149] In some embodiments, network device 102 receives third information sent by terminal 101.
[0150] In some embodiments, the third information is used to indicate a second non-serving cell. The terminal can indicate the second non-serving cell to the network device, that is, indicate which non-serving cells the terminal supports in determining its predicted value based on a first value of the serving cell. For example, different serving cells result in different second non-serving cells. Furthermore, due to different cell or base station deployments in different locations, the distribution of neighboring cells is also different. For example, in cities, suburbs, shopping malls, stadiums, etc., due to different population densities, cell or base station deployments are different, and consequently, the distribution of neighboring cells is also different. Exemplarily, FIG2b is a schematic diagram illustrating the distribution of a serving cell and a first non-serving cell according to an embodiment of this disclosure. As shown in FIG2b, the serving cell is a hexagonal box filled with diagonal stripes in the middle, and the first non-serving cell is a hexagonal box filled with dots. The first non-serving cells are distributed around the serving cells. FIG2b is merely exemplary; for example, in other exemplary embodiments, small cells may also exist within the hexagonal boxes filled with diagonal stripes. Therefore, when the terminal is in different serving cells, the third information can indicate the second non-serving cell corresponding to the serving cell.
[0151] For example, each first non-serving cell corresponds to a different location, and the required AI model is also different. For some first non-serving cells, the terminal may not have prepared the required AI model, or even if it has, it may be unable to run the AI model due to insufficient power. This indicates that the terminal does not support determining the second value corresponding to the first non-serving cell based on the first value corresponding to the serving cell; that is, the first non-serving cell cannot be used as a second non-serving cell, or the AI model corresponding to that first non-serving cell is not applicable. Conversely, for some first non-serving cells, the terminal may have prepared the required AI model, or it may have prepared the required AI model and be able to run it due to sufficient power. This indicates that the terminal supports determining the second value corresponding to the first non-serving cell based on the first value corresponding to the serving cell; that is, the first non-serving cell can be used as a second non-serving cell, or the AI model corresponding to that first non-serving cell is applicable. The terminal can indicate the second non-serving cell to the network device through third information.
[0152] For example, even if different first non-serving cells are in the same location, the required information configuration may differ. This information configuration is used to improve the performance of the AI model. For instance, if the terminal does not receive the required information configuration for some first non-serving cells, it means that the terminal does not support determining the second value corresponding to the first non-serving cell based on the first value corresponding to the serving cell; that is, the first non-serving cell cannot be used as a second non-serving cell. If the terminal has received the required information configuration for some first non-serving cells, it means that the terminal supports determining the second value corresponding to the first non-serving cell based on the first value corresponding to the serving cell; that is, the first non-serving cell can be used as a second non-serving cell. The terminal can indicate the second non-serving cell to the network device through third information.
[0153] For example, based on third information, network devices can determine which non-serving cells the terminal supports based on the first value of the serving cell and determine its second value. For those non-serving cells that the terminal does not support (i.e., cells other than the second non-serving cell in the first non-serving cell, assuming to be the third non-serving cell), network devices can configure resources for the terminal to measure the third non-serving cell.
[0154] For example, if a network device configures a terminal to measure resources of a third non-serving cell, the terminal can measure the third non-serving cell to obtain a fifth value. The fifth value may include quality information corresponding to the third reference signal resource, the identifiers of the H reference signal resources with the best quality information in the third reference signal resource set, and the identifiers of the third non-serving cells corresponding to the L reference signal resources with the best quality information in the third reference signal resource set. H and L are positive integers, and their values can be the same or different. The third reference signal resource is at least one reference signal resource in the third reference signal resource set, and the third reference signal resource set is the set of reference signal resources corresponding to each non-serving cell in at least one third non-serving cell. When the terminal sends a report to the network device, the report may include either a second or a fifth value. The second and fifth values are essentially quality information or identifiers, and the network device may not be able to determine which values are predicted and which are measured. Therefore, the terminal can associate the reported quantities (i.e., quality information and / or identifiers) with the identifiers of the second non-serving cells in the report so that the network device can determine which reported quantities are predicted and the others are measured. Alternatively, even without establishing a correlation, if the reported quantity includes the identifiers of the non-serving cells corresponding to the Q+L reference signal resources with the best quality information, the network device can also determine which are the identifiers of the second non-serving cells and which are the identifiers of the third non-serving cells. For example, if there are N second non-serving cells, the terminal indicates these N second non-serving cells through third information (for example, the third information may include the number of the second non-serving cell, and the network device can determine the identifier of the second non-serving cell based on this number; or, for example, the third information may include the identifier of the second non-serving cell; see the embodiments below for specific implementation details). That is, the network device can determine the identifiers of the N second non-serving cells based on the third information. When the terminal sends the second and fifth values to the network device in the report, assuming the second value includes the identifiers of the second non-serving cells corresponding to the Q reference signal resources with the best quality information (i.e., the identifiers of the Q second non-serving cells), and the fifth value includes the identifiers of the third non-serving cells corresponding to the L reference signal resources with the best quality information (i.e., the identifiers of the L third non-serving cells), the network device only sees L+Q identifiers in the report. However, since the network device has already identified the identifiers of the N second non-serving cells, some of the L+Q identifiers belong to the N second non-serving cell identifiers. That is, some of the L+Q identifiers are the same as some of the N second non-serving cell identifiers. These are the Q second non-serving cell identifiers. In other words, the network device can determine which of the L+Q identifiers are the Q second non-serving cell identifiers, and the rest are the L third non-serving cell identifiers.
[0155] In some embodiments, the third information includes at least one of the following: the number of the second non-serving cell in the list; the physical cell identifier of the second non-serving cell; and the globally unique identifier of the second non-serving cell.
[0156] Optionally, the third information may include the number of the second non-serving cell in the list.
[0157] For example, if a terminal receives a fourth message from a network device, and this fourth message includes the number of the first non-serving cell in the list, the terminal can determine the second non-serving cell from it. That is, it can identify some or all of the first non-serving cells as the second non-serving cell, and use the number of the first non-serving cell as the number of the second non-serving cell. This number is then included in the third message and sent to the network device. For instance, if the fourth message sent by the network device to the terminal includes first non-serving cell #1 and first non-serving cell #2, and if the terminal determines that it supports the first value based on the serving cell and determines the second value corresponding to first non-serving cell #1, but does not support the first value based on the serving cell and determines the second value corresponding to first non-serving cell #2, then the terminal can include the number "#1" in the third message and send it to the network device.
[0158] For example, the terminal can store a table containing the correspondence between serving cell identifiers and second non-serving cell identifiers. The terminal can determine the number of the second non-serving cell from the table based on its current serving cell and include this number in the third information before sending it to the network device. For instance, the table stored by the terminal could be Table 2. As shown in Table 2, if the terminal's current serving cell is serving cell #1, then the second non-serving cells include second non-serving cell #1,1, second non-serving cell #1,2, second non-serving cell #1,3, etc., and the third information can include the numbers "#1,1", "#1,2", "#1,3", etc. If the terminal's current serving cell is serving cell #2, then the second non-serving cells include second non-serving cell #2,1, second non-serving cell #2,2, second non-serving cell #2,3, etc., and the third information can include the numbers "#2,1", "#2,2", "#2,3", etc. If the terminal's current serving cell is serving cell #3, then the second non-serving cells include second non-serving cells #3,1, #3,2, #3,3, etc. The third information may include numbers such as "#3,1", "#3,2", and "#3,3". The ellipsis in Table 2 indicates "etc.", meaning that the serving cells are not limited to those listed in the table and may include other serving cells. Similarly, the second non-serving cells corresponding to each serving cell are not limited to those listed in the table and may also include other second non-serving cells.
[0159] Table 2
[0160] It is understood that Tables 1 and 2 of this disclosure are exemplary and are not intended to limit the scope of the disclosure.
[0161] In some embodiments, the third information includes multiple bits, wherein each bit corresponds to a first non-serving cell. If the bit displays a third value, it indicates that the first non-serving cell corresponding to the bit is a second non-serving cell. If the bit displays a fourth value, it indicates that the first non-serving cell corresponding to the bit is a cell other than the second non-serving cell among the first non-serving cells.
[0162] For example, the third value can be 1, and the fourth value can be 0. Assuming the serving cell corresponds to three first non-serving cells, the second information can include three bits, which, from left to right, correspond to first non-serving cell 1, first non-serving cell 2, and first non-serving cell 3, respectively. If the three bits are 001, it indicates that first non-serving cell 3 is a second non-serving cell. If the three bits are 010, it indicates that first non-serving cell 2 is a second non-serving cell. If the three bits are 101, it indicates that first non-serving cell 1 and first non-serving cell 3 are second non-serving cells. If the three bits are 111, it indicates that all three first non-serving cells are second non-serving cells. This disclosure does not provide a complete list, nor does it limit the number of first non-serving cells, the number of bits, or which first non-serving cell is a second non-serving cell.
[0163] In some embodiments, if the terminal receives the fourth information, it may send the third information including multiple bits to the network device. If the fourth information is not received, the terminal may send the third information including at least one of the following: the number of the second non-serving cell in the list, the physical cell identifier of the second non-serving cell, and the globally unique identifier of the second non-serving cell to the network device.
[0164] In some embodiments, the name of the third information is not limited, and it may be, for example, "reported information" or "instruction information".
[0165] In some embodiments, the second and third information can be contained in the same message, meaning they can be sent to the network device simultaneously. Alternatively, the second and third information can be contained in different messages, meaning they can be sent to the network device at different times.
[0166] It is understood that step S2103 is optional. For example, if the network device can determine the second non-serving cell corresponding to the serving cell of the terminal on its own, for example, if the protocol can specify the second non-serving cell corresponding to the serving cell of the terminal, then step S2103 is optional.
[0167] In step S2104, network device 102 sends first information to terminal 101.
[0168] In some embodiments, the terminal receives first information sent by the network device.
[0169] In some embodiments, the first information is used to configure the first reference signal resources, which are each reference signal resource in the first reference signal resource set corresponding to the serving cell. For details, please refer to the above embodiments, which will not be repeated here.
[0170] In some embodiments, the terminal may obtain a first value based on a first reference signal resource. For example, the terminal may measure a reference signal on the first reference signal resource to obtain the first value.
[0171] In some embodiments, the network device configures a first reference signal resource to the terminal via first information, so that the terminal can measure the reference signal on the first reference signal resource and obtain a first value.
[0172] In some embodiments, the name of the first information is not limited, and it may be, for example, "configuration information".
[0173] In step S2105, terminal 101 measures the reference signal on the first reference signal resource to obtain the first value corresponding to the serving cell.
[0174] In some embodiments, the terminal may measure the reference signal on the first reference signal resource to obtain a first value corresponding to the serving cell. A detailed description of the first value can be found in the above embodiments, and will not be repeated here.
[0175] In step S2106, terminal 101 determines a second value corresponding to one or more non-serving cells based on the first value corresponding to the serving cell.
[0176] In some embodiments, the terminal can determine a second value corresponding to one or more non-serving cells based on a first value corresponding to the serving cell. For example, the terminal can deploy an AI model (the AI model can be replaced by an AI function, or an ML function, or an ML model; this embodiment uses an AI model as an example for illustration, but is not limited thereto), input the first value corresponding to the serving cell into the AI model, and the AI model outputs the second value of the non-serving cell.
[0177] In some embodiments, the AI model deployed on the terminal can be pre-trained by the terminal or trained by a network device and sent to the terminal. For example, the terminal or network device can train the AI model based on training data, which may include the input data of the AI model and the output data to be learned from the actual output results of the AI model. That is, the input data is input into the AI model, and the parameters are adjusted so that the actual output results tend to the output data. For example, the input data may be measurement values obtained from measuring a reference serving cell, which may include quality information corresponding to the reference signal resources of the reference serving cell. The output data may be measurement values obtained from measuring a reference non-serving cell corresponding to the reference serving cell, which may include quality information corresponding to the reference signal resources of the reference non-serving cell, the probability that the reference non-serving cell is the strongest non-serving cell, the probability that the quality information corresponding to the reference signal resources of the reference non-serving cell is the highest, etc. Of course, this disclosure does not limit the training process.
[0178] In step S2107, terminal 101 sends a report to network device 102.
[0179] In some embodiments, network device 102 receives a report sent by terminal 101.
[0180] In some embodiments, the report includes at least one of the second values.
[0181] In some embodiments, the report includes at least one of the first values.
[0182] In some embodiments, for a third non-serving cell (i.e., a cell other than the second non-serving cell in the first non-serving cells), since the terminal does not support determining the second value of the third non-serving cell based on the first value of the serving cell, the network device can configure the resources required for measurement of the third serving cell. The terminal can measure the third serving cell to obtain a fifth value; for details, please refer to the above embodiments, which will not be repeated here. The report may also include the fifth value.
[0183] In some embodiments, the report may also be referred to as a first report, a beam report, an L3 report, an RRM report, a CSI report, etc. For example, when the second or fifth value includes at least one of L1-RSRP and L1-SINR, the first report may be called a beam report. When the second or fifth value includes at least one of L3-RSRP, L3-RSRQ, and L3-RSSI, the first report may be called an RRM report or a Layer 3 report. When the first value includes the CSI corresponding to the first reference signal resource, the first report may be called a CSI report.

For example, steps S2106 and S2107 may be implemented as separate embodiments, step S2101 may be implemented as an independent embodiment, steps S2101 and S2103 may be implemented as separate embodiments, and steps S2101 to S2103 and step S2104 may be implemented as separate embodiments, but are not limited thereto.

[0258] Figure 5 is a schematic diagram illustrating the communication method interaction according to an embodiment of the present disclosure. As shown in Figure 5, the embodiments of the present disclosure relate to a communication method, which includes:
[0259] In step S5101, terminal 101 determines a second value corresponding to one or more non-serving cells based on the first value corresponding to the serving cell.
[0260] In step S5102, terminal 101 sends a report to network device 102.
[0261] 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.
[0262] This disclosure provides a communication method as follows:
[0263] In some embodiments, the terminal reports second information, which is used to instruct the terminal to obtain the (beam) prediction value of the non-serving cell (or neighboring cell) based on the (beam) measurement value of the serving cell.
[0264] In some embodiments, the terminal reports third information, which is used to indicate the non-serving cells supported by the terminal.
[0265] In step 1), the terminal first reports its ability to obtain beam prediction values for non-serving cells based on beam measurement values from the serving cell. In step 2), the terminal determines, based on its current serving cell, which non-serving cells it can obtain beam prediction values for.
[0266] In some embodiments, considering cell deployment, a terminal may have many neighboring cells within the coverage area of a serving cell. The specific neighboring cell beam prediction values that the terminal's AI / ML functions / models can support need to be communicated to the network. This is because each neighboring cell has a different location, and consequently, different AI / ML functions / models. Even if they are the same, some configuration information may be required to improve the performance of the AI / ML functions / models. Therefore, when a terminal connects to a new serving cell, it needs to report to the current serving cell which neighboring cells it can obtain beam prediction values for. In other words, the terminal may maintain a table showing which neighboring cells the terminal can support for beam prediction in different serving cells. For example, Table 2 shows that the neighboring cells differ depending on the terminal's serving cell, and the distribution of neighboring cells also varies due to different cell or base station deployments in different locations. For example, in some areas, the cell distribution is as shown in Figure 2b. The cell represented by the diagonally filled hexagonal square has only six neighboring cells. However, in other areas, the cell distribution is different: for instance, the cell represented by the diagonally filled hexagonal square may contain small cells. When all terminals are in different serving cells, the network equipment needs to be informed which neighboring cells the terminal can predict. Of course, some neighboring cells may be the same for different serving cells.
[0267] In some embodiments, the third information includes at least one of the following:
[0268] The non-serving cell's number in the list (the corresponding PCI terminal and network are also known, for example, the network device has already sent the corresponding relationship to the terminal);
[0269] PCI for non-serving cells;
[0270] The globally unique identifier for a non-serving cell is its cell global ID;
[0271] Each non-serving cell corresponds to X bits (the first value of the X bit indicates support; the second value indicates non-support; for example, '0' indicates non-support and '1' indicates support).
[0272] In some embodiments, before sending the third information, the terminal receives a fourth information sent by the network device. The fourth information is used to instruct the terminal to report which non-serving cells' beam prediction is supported by the terminal-side AI / ML function / model.
[0273] In some embodiments, the fourth information provides the identifiers of some non-serving cells, the identifiers including at least one of the first three items in (iii), and then the terminal reports the third information, which may be the fourth item in (iii).
[0274] In some embodiments, if no fourth message is received before the third message, the third message sent by the terminal may be at least one of the first three items in (iii).
[0275] In some embodiments, the measured values include at least one of the following corresponding to each reference signal resource in the reference signal resource set corresponding to the serving cell: L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, CSI (PMI, RI, CQI, etc.).
[0276] To broaden the scope, the "beam measurement value" in section (a) can be replaced with "measurement value". Here, L1-RSRP and L1-SINR correspond to beam measurement values; L3-RSRP, L3-RSRQ, and L3-RSSI correspond to RRM or L3 measurement values; and CSI (PMI, RI, CQI, etc.) correspond to CSI measurement values.
[0277] In some embodiments, the reference signal resource may be an SSB or a CSI-RS.
[0278] In some embodiments, the predicted value includes at least one of the following corresponding to at least one reference signal resource in the reference signal resource set corresponding to the non-serving cell.
[0279] Top Q non-serving cell identifiers;
[0280] At least one of the following is included in the second reference signal resource set of at least one non-serving cell: L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, CSI (PMI, RI, CQI, etc.);
[0281] At least one of the top K reference signal resource identifiers in the second reference signal resource set of each non-serving cell;
[0282] Top K refers to the top K reference signal resources when sorted from strongest to weakest based on at least one of the following: L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, CSI (PMI, RI, CQI, etc.).
[0283] For example:
[0284] Case 1: The most comprehensive model output is at least one of the following measurements corresponding to each of the second reference signal resource sets for each non-serving cell: L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, and CSI (PMI, RI, CQI, etc.). Based on this output, the terminal can obtain the strongest reference signal resource corresponding to the strongest measurement, and the strongest non-serving cell corresponding to the strongest reference signal resource. In other words, the terminal can obtain the strongest non-serving cell identifier and the strongest reference signal resource identifier through all the measurements output by the model. Therefore, regardless of whether the network device requires the terminal to report the strongest non-serving cell identifier, the strongest reference signal resource identifier, or a measurement, the terminal can obtain it.
[0285] Case 2: Another model's output may not include the predicted values of measurements corresponding to each reference signal resource. For example, it might include the probability that each non-serving cell is the strongest non-serving cell. In this case, the terminal, based on the model output, can only obtain the identifier of the strongest non-serving cell, i.e., the non-serving cell with the highest probability. It cannot obtain the identifier of the strongest reference signal resource, nor the predicted values of the measurements corresponding to the reference signal resource.
[0286] Case 3: In another model, the output may not include the predicted value of the measurement corresponding to each reference signal resource. For example, it may include the probability that the measurement corresponding to each reference signal resource of each non-serving cell is the highest. In this case, the terminal can only obtain the identifier of the strongest reference signal resource based on the model output, and further, the identifier of the strongest non-serving cell corresponding to the strongest reference signal resource. It cannot obtain the predicted value of the measurement corresponding to the reference signal resource.
[0287] In some embodiments, the terminal sends a first report, which includes at least one of the predicted values.
[0288] 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.
[0289] 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.
[0290] 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.
