[0029] In a first aspect, an embodiment of the present disclosure proposes a communication method, which includes: a terminal receives first information sent by a network device, where the first information is used to indicate beam information corresponding to multiple time instances.
[0030] In the above embodiment, by receiving the first information, the first information indicates the beam information corresponding to multiple time instances, thereby achieving simultaneous indication of the beam information of multiple time instances, saving signaling, reducing latency, and improving communication efficiency.
[0031] In combination with some embodiments of the first aspect, in some embodiments, the first information is also used to indicate at least one of the following: the number of time instances N, where N is a positive integer; M time values, where one time value represents the application time of the beam information corresponding to one time instance in the multiple time instances, where the application time includes a start time or an end time, and M is a positive integer less than or equal to N; L time interval values, where one time interval value represents the time interval between the application times of different beam information, where the application time includes a start time or an end time, and L is a positive integer less than or equal to N.
[0032] In the above embodiment, by indicating at least one of the numerical value N, M time values, and L time interval values, it is possible to indicate the application time of multiple time instances in a variety of ways, so as to simultaneously indicate the application time of beams of multiple time instances, save resource consumption, and improve communication efficiency.

[0034] In the above embodiment, multiple sets of parameters can be preconfigured by first signaling, where each set of parameters includes one or more of a numerical value N, M time values, and L time interval values, and one of the sets of parameters is activated by second signaling. This enables faster indication of beam application times at multiple time instances.

[0036] In the above embodiment, beam information for multiple time instances can be configured using the first information. The beam information corresponding to each time instance includes a set of beam information, each of which includes information about one or more beams.

The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 .

[0109] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0110] In the disclosed embodiments, in NR, especially when the communication frequency band is in frequency range 2, since the high-frequency channel attenuates rapidly, beam-based transmission and reception are required to ensure coverage.
[0111] In some traditional beam management processes, network equipment configures a set of reference signal resources for beam measurement. The terminal measures the reference signal resources in this set and reports the IDs of some of the stronger reference signal resources, along with the corresponding layer 1 reference signal received power (L1-RSRP) and / or layer 1 signal to interference plus noise ratio (L1-SINR), to the network equipment.
[0112] In related art, it is assumed that the reference signal resource set configured by a network device includes X reference signal resources, each of which corresponds to a different transmit beam of the network device. For each reference signal resource, the terminal needs to use all receive beams to measure the reference signal. This results in obtaining the beam measurement qualities corresponding to all receive beams. In some cases, one or more best beam measurement qualities and / or the beam identifier corresponding to the best beam measurement quality can be determined. Therefore, the number of beam pairs that the terminal needs to measure is G*H. Here, G represents the number of transmit beams of the network device, and H represents the number of receive beams of the terminal.
[0113] In some embodiments, an AI model and / or AI function is provided to implement beam prediction, wherein an AI function can be considered as one or more AI models that implement the same function and purpose.
[0114] In some embodiments, the AI model used for beam prediction can be referred to as a beam prediction model. Of course, it can also be referred to as a beam prediction AI model, a prediction AI model, a predicted beam model, etc. This disclosure does not limit the names of such AI models.
[0115] In some implementations, when the beam prediction model uses spatial prediction, the terminal measures the L1-RSRP of set B and inputs the measured value into the beam prediction model. The beam prediction model can predict the L1-RSRP of the best beam and / or beam pair in set A, and / or the identifier of the best beam and / or beam pair in set A.
[0116] The relationship between set B and set A includes the following two types:
[0117] The first relationship is that 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 some of them, for example, set B contains 8 of the 32 reference signal resources.
[0118] The second relationship is that 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 signal resources cover a 120-degree direction). Set B contains another Y reference signal resources, for example, Y = 8. These Y reference signal resources also cover a 120-degree direction, that is, the beam direction of each reference signal resource in set B covers the beam directions of multiple reference signal resources in set A. It can be understood that the relationship between the 32 / Y reference signal resources in set A and the one reference signal resource in set B is QCL Type D.
[0119] It should be understood that the examples of the first and second relationships described above only describe the transmit beam case. When considering beam pairs consisting of transmit and receive beams, the terminal's receive beams must also be considered. For example, if there are 32 transmit beams and 4 receive beams, then set A consists of 32*4 beam pairs, and set B can consist of 32 beam pairs, 16 beam pairs, and so on.
[0120] In some embodiments, if the performance of the beam prediction model does not need to be monitored, assuming that the AI model has been trained in advance, the network device only needs to periodically send the reference signal on the reference resource of set B (for example, the first period). The terminal then measures the L1-RSRP of the reference signal on the reference signal resource in set B and inputs it into the beam prediction model. This outputs the L1-RSRP corresponding to the reference signal resource of set A or the strongest one or more reference signal resource IDs among the 32 reference signal resources in set A.
[0121] In some embodiments, if it is necessary to monitor the performance of the beam prediction model, the network device is required to periodically send the reference signal on the reference signal resource of set A (for example, the second period). Then the terminal needs to measure the L1-RSRP of the reference signal on the reference signal resource of set B. For the terminal side model, the terminal inputs the measured L1-RSRP of the reference signal on the reference signal resource of set B into the beam prediction model, obtains the predicted beam information, and reports it to the network device; for the network side model, the terminal reports the measured L1-RSRP and / or identifier of the reference signal on the reference signal resource of set B to the network device, and the network device inputs the L1-RSRP and / or identifier of the reference signal on the reference signal resource of set B into the beam prediction model to obtain the predicted beam information. At the same time, the terminal also measures the L1-RSRP of the reference signals on all reference signal resources in set A, and reports the measured L1-RSRP and / or identifier of the reference signals on all reference signal resources in set A, and / or the L1-RSRP and / or identifier of the best L beams / beam pairs as the beam information obtained by the traditional method to the base station.
[0122] In various embodiments of the present disclosure, the terms "terminal-side model" and "AI model deployed on the terminal" can be used interchangeably. The terms "network device-side model" and "AI model deployed on the network device" can be used interchangeably.
[0123] In some implementations, when the beam prediction model uses time-domain prediction, the terminal measures the L1-RSRP at historical time set B and inputs this into the beam prediction model to predict the L1-RSRP at future time value set A. In addition to the two aforementioned relationships between set B and set A, there is another relationship in which set B and set A are identical.
[0124] When beam measurement is performed using the related art method, the base station also needs to transmit reference signals for future time values. The terminal measures the reference signals for future time values and reports the measured beam information to the network device. Specifically, the terminal needs to measure and report the beam information for all beams and / or beam pairs in set A to the network device.
[0125] In some embodiments, the beam information of a time instance can be indicated, for example, by a medium access control element (MAC CE) or downlink control information (DCI). However, for time-domain beam prediction, if the AI model can predict the beam information of multiple time instances, then the beam information of each time instance is indicated separately through MAC CE or DCI, resulting in excessive signaling consumption and large latency.
[0126] FIG2 is a schematic diagram illustrating an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to a communication method for use in a communication system 100, the method comprising:
[0127] Step S2101 , the network device 102 sends first information to the terminal 101 .
[0128] In some embodiments, the terminal 101 receives first information sent by the network device 102 .
[0129] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.
[0130] 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.
[0131] 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", and "parameter" can be used interchangeably.
[0132] In some embodiments, the first information is used to indicate beam information corresponding to multiple time instances.
[0133] In some embodiments, a time instance can be a predicted time instance. For example, in time-domain beam prediction, an AI model outputs beam information for multiple time instances, and this time instance is a predicted time instance. A time instance can also be a measured time instance. For example, a terminal actually measures beam information for multiple time instances and sends it to a network device, and this time instance is a measured time instance. The multiple time instances can include measured time instances and / or predicted time instances.
[0134] In some embodiments, the beam information includes one or more of a transmission configuration indication (TCI) state and spatial relationship information (spacingrelationinfo). The TCI state includes at least one of the following: a joint TCI state; a downlink TCI state; and an uplink TCI state.
[0135] In some embodiments, terms such as "uplink", "uplink", "physical uplink" can be interchangeable with each other, and terms such as "downlink", "downlink", "physical downlink" can be interchangeable with each other, and terms such as "side", "sidelink", "side communication", "sidelink communication", "direct connection", "direct link", "direct communication", "direct link communication" can be interchangeable with each other.
[0136] In some embodiments, the terms "downlink control information (DCI)", "downlink (DL) assignment", "DL DCI", "uplink (UL) grant", "UL DCI" and the like may be used interchangeably.
[0137] In some embodiments, the terms "precoding", "precoder", "weight", "precoding weight", "quasi-co-location (QCL)", "transmission configuration indication (TCI) state", "spatial relation", "spatial domain filter", "transmission power", "phase rotation", "antenna port", "antenna port group", "layer", "the number of layers", "rank", "resource", "resource set", "resource group", "beam", "beam width", "beam angular degree", "antenna", "antenna element", "panel" and the like can be used interchangeably.
[0138] In some embodiments, the combined TCI state may also be referred to as an uplink and downlink combined TCI state. The combined TCI state may be used for both uplink and downlink transmissions.
[0139] In some embodiments, the first information is further used to indicate at least one of the following: the number N of time instances, where N is a positive integer; M time values, where each time value represents an application time (application time) of the beam information corresponding to a time instance among the multiple time instances. The application time includes a start time or an end time, where M is a positive integer less than or equal to N; and L time interval values, where each time interval value represents a time interval between application times of different beam information, where the application time includes a start time or an end time, where L is a positive integer less than or equal to N.
[0140] In some embodiments, the first information may be used to indicate the number N of time instances, where N is a positive integer.
[0141] For example, the network device may indicate the number of time instances N to the terminal, and the terminal may determine the time interval value between each time instance by itself, thereby determining the application time of each time instance. The application time of the time instance represents the time when the beam information corresponding to the time instance is applied. The application time may be the start time, that is, the start time of applying the beam information corresponding to the time instance. The application time may also be the end time, that is, the end time of applying the beam information of the time instance. For example, the number of time instances is N, and the start time of the beam information corresponding to the first time instance may be determined by the terminal. For example, it may be determined based on the time when the first information is received, or the time after a preset time offset after the first information is received. The start time of the beam information corresponding to the second time instance may be the time after the start time of the beam information corresponding to the first time instance passes the time interval value, and the start time of the beam information corresponding to the Nth time instance may be the time after the start time of the beam information corresponding to the first time instance passes the (N-1) time interval value. The time interval value may be determined based on preconfiguration or predefinition. The time interval values between two different adjacent time instances may be the same or different.
[0142] In some embodiments, the first information may be used to indicate M time values.
[0143] For example, the network device can indicate M time values to the terminal. Each time value represents the start time or end time of the beam information corresponding to a time instance in multiple time instances. Among them, M is a positive integer less than or equal to N. For example, when the time value represents the start time of the beam information corresponding to the time instance, the start time of the first time instance can be determined based on the time when the first information is received, or the time after a preset time offset after the first information is received. That is, the start time of the first time instance does not need to be indicated. In this case, M is less than N. When the time value represents the end time of the beam information corresponding to the time instance, the end time of the beam information corresponding to the first time instance needs to be indicated. The end time of the beam information corresponding to the last time instance may also not be indicated. If the end time of the beam information corresponding to the last time instance is indicated, that is, the end time of the beam information corresponding to each time instance needs to be indicated. In this case, M is equal to N. If the end time of the beam information corresponding to the last time instance does not need to be indicated, for example, the end time of the beam information corresponding to the last time instance is the start time of the beam information corresponding to the first time instance indicated by the next first information, in this case, M is less than N.
[0144] In some embodiments, the first information may be used to indicate L time interval values, where L is a positive integer less than or equal to N.
[0145] For example, the network device may indicate L time interval values to the terminal. Each time interval value represents the time interval between application times of beam information corresponding to different time instances.
[0146] In some embodiments, the time interval value may be a start time and a time interval between the start times. For example, the start time of the beam information corresponding to the first time instance may be determined by the terminal. For example, the terminal determines the start time of the beam information corresponding to the first time instance based on the time when the first information is received, or the time after a preset time offset after receiving the first information. The start time of the beam information corresponding to the second time instance may be determined based on the start time of the beam information corresponding to the first time instance, and the time interval value between the first time instance and the second time instance in the L time interval values. The start time of the beam information corresponding to the Nth time instance may be determined based on the start time of the beam information corresponding to the (N-1)th time instance, and the time interval value between the (N-1)th time instance and the Nth time instance in the L time interval values. At this time, the N time instances correspond to a total of (N-1) time interval values, that is, L is less than N. The time interval values between two different adjacent time instances may be the same or different.
[0147] In some embodiments, the time interval value can be the end time and the time interval between the end times. For example, the start time of the beam information corresponding to the first time instance can be determined by the terminal, and the end time can be configured by the network device or determined based on predefined rules. The end time of the beam information corresponding to the second time instance can be determined based on the end time of the beam information corresponding to the first time instance, and the time interval value between the first time instance and the second time instance in the L time interval values. The end time of the beam information of the Nth time instance can be determined based on the end time of the beam information corresponding to the (N-1)th time instance, and the time interval value between the (N-1)th time instance and the Nth time instance in the L time interval values. At this time, the N time instances correspond to a total of (N-1) time interval values, that is, L is less than N. The time interval values between two different adjacent time instances may be the same or different.
[0148] In some embodiments, the time interval value may be the time interval between the start time and the end time. For example, the start time of the beam information corresponding to the first time instance may be determined by the terminal. The end time of the first time instance may be determined based on the start time of the beam information corresponding to the first time instance and the time interval value between the start time and the end time of the beam information corresponding to the first time instance in the L time interval values. The start time of the beam information corresponding to the Nth time instance may be determined based on the end time of the beam information corresponding to the (N-1)th time instance. The end time of the Nth time instance may be determined based on the start time of the beam information corresponding to the Nth time instance and the time interval value between the start time and the end time of the beam information corresponding to the Nth time instance in the L time interval values. At this time, the N time instances correspond to a total of N time interval values, that is, L is equal to N. The time interval values between two different adjacent time instances may be the same or different.
[0149] In some embodiments, the time interval value may be the time interval between the end time and the start time. The end time of the beam information corresponding to the first time instance is the same as the start time of the beam information corresponding to the second time instance. For example, the time interval value may be the time interval between the end time of the beam information corresponding to the first time instance and the start time of the beam information corresponding to the third time instance. The time interval value may also be considered as the time interval between the start time and the end time of the beam information corresponding to the second time instance.
[0150] For example, the start time of the beam information corresponding to the first time instance can be determined by the terminal, and the end time can be configured by the network device or determined based on predefined rules. The start time of the beam information corresponding to the second time instance can be determined based on the end time of the beam information corresponding to the first time instance. The end time of the beam information corresponding to the second time instance can be determined based on the end time corresponding to the first time instance, and the time interval value between the end time of the beam information corresponding to the first time instance and the start time of the beam information corresponding to the third time instance in the L time interval values. The end time of the beam information corresponding to the (N-1)th time instance can be determined based on the end time of the beam information corresponding to the (N-2)th time instance, and the time interval value between the end time of the beam information corresponding to the (N-2)th time instance and the start time of the beam information corresponding to the Nth time instance in the L time interval values. The start time of the beam information corresponding to the Nth time instance is determined based on the end time of the beam information corresponding to the (N-1)th time instance. The end time of the beam information corresponding to the Nth time instance can be determined by the terminal, or can be configured by the network device or determined based on predefined rules. In this case, N time instances correspond to (N-2) time interval values in total, that is, L is less than N. Two different adjacent time interval values may be the same or different.
[0151] In some embodiments, the first information may be radio resource control (RRC), where RRC is used to configure M time values. Alternatively, RRC is used to configure N number of time instances and L time interval values.
[0152] In some embodiments, RRC is used to configure M time values.
[0153] In some embodiments, RRC is used to configure the number N of time instances and L time interval values. The time interval value may be at least one of the time interval value between a start time and a start time, the time interval value between an end time and an end time, the time interval value between a start time and an end time, and the time interval value between an end time and a start time. For example, the network device may indicate the number N of time instances and the time interval value between each time instance to the terminal, thereby determining the application time of each time instance. The terminal does not need to independently determine the time interval value between each time instance.
[0154] In some embodiments, the first information may indicate M time values and L time interval values. For example, the M time values may be the start time of the beam information corresponding to the first time instance, and the L time interval values may be the time interval values of the start time of the beam information corresponding to each time instance. For another example, the M time values may be the start time and end time of the beam information corresponding to the first time instance, and the L time interval values may be the time interval values of the end time of the beam information corresponding to each time instance. For another example, the M time values may be the start time of the beam information corresponding to the first time instance. The L time intervals may be the time interval values between the start time and the end time. For another example, the M time values may be the start time and end time of the beam information corresponding to the first time instance and the end time of the beam information corresponding to the Nth time instance, and the L time interval values may be the time interval values between the end time and the start time.
[0155] In some embodiments, the first information may indicate a number N of time instances, M time values, and L time interval values.
[0156] In some embodiments, the first information is configured based on first signaling and second signaling. The first signaling is used to pre-configure multiple sets of parameters, each of which includes one or more of the number of time instances (N), M time values, and L time interval values. The second signaling is used to activate one or more of the multiple sets of parameters.
[0157] In some embodiments, the multiple groups of parameters may include, for example, group A parameters and group B parameters. Group A parameters include M time values, and group B parameters include N number of time instances and L time interval values. The second signaling may be used to activate group A parameters, group B parameters, or both.
[0158] Of course, the above-mentioned group A parameters and group B parameters are merely exemplary. For example, group C parameters may also be included, where group C parameters include M time values and L time interval values, or group C parameters also include M time values, or group C parameters also include N number of time instances and L time interval values. This disclosure does not list all of these examples, and the above-mentioned exemplary examples are not limiting.
[0159] In some embodiments, the first signaling may be used to configure L time interval values. The second signaling is used to configure the number N of time instances.
[0160] In some embodiments, the first signaling may be RRC and the second signaling may be MAC CE.
[0161] In some embodiments, one time instance corresponds to a set of beam information, wherein the set of beam information includes information of one or more beams.
[0162] In some embodiments, the beam information includes at least one of the following: first beam information of multiple time instances corresponding to a code point; second beam information of one time instance corresponding to a code point; third beam information of multiple time instances corresponding to multiple code points, and at least one code point among the multiple code points corresponds to multiple time instances; fourth beam information of multiple time instances corresponding to multiple code points, and at least one code point among the multiple code points corresponds to one time instance.
[0163] In some embodiments, one code point corresponds to K time instances, each of the K time instances corresponds to H pieces of first beam information, and the H pieces of first beam information represent information about H first beams. K is determined based on the third signaling. K is an integer greater than 1. The number H of first beam information corresponding to different time instances can be the same or different.
[0164] In some embodiments, the third signaling may be RRC.
[0165] In some embodiments, the first information is also used to determine at least one of the following: the code point corresponding to the first beam information; the position of the time instance corresponding to the first beam information in K time instances; the number H of first beams corresponding to each time instance; the position of the first beam information in H first beam information.
[0166] In some embodiments, the first information may be a MAC CE.
[0167] In some embodiments, the first information may be used to activate beam information of multiple time instances corresponding to one code point.
[0168] In some embodiments, the position of the time instance corresponding to the first beam information in the K time instances may be determined according to the bit position of the first information corresponding to the first beam information.
[0169] In some embodiments, the first information may include multiple subscripts corresponding to the first beam information. Different subscripts are used to determine the code point corresponding to the first beam information, the position of the time instance corresponding to the first beam information in the K time instances, the position of the first beam information in the H first beam information, etc. For example, the beam information may be a TCI state, and the first subscript of the TCI is used to indicate the code point corresponding to the TCI. The second subscript indicates the time instance to which the TCI corresponds. The third subscript indicates the TCI state in the corresponding time instance. For example, the first TCI state or the second TCI state. The first information may also include a first identifier, for example, the first identifier may be called a Pi identifier, which is used to determine the number of first beams corresponding to each time instance.
[0170] For example, the beam information may be a TCI state, and the beam information of multiple time instances corresponding to a code point indicated by the first information may be shown in Table 1. Table 1 also includes a Pi identifier.
[0171] Table 1 represents the beam information of multiple time instances corresponding to the 0th code point. Among them, P0, P1, and P2 represent the first identifier in the fourth signaling, that is, the Pi identifier. For example, P0 represents the number of beam information corresponding to the 0th time instance. P1 represents the number of beam information corresponding to the 1st time instance. P2 represents the number of beam information corresponding to the 2nd time instance. TCI0,0,0 and TCI0,0,1 represent the two TCI states of the 0th time instance corresponding to the 0th code point. Among them, TCI0,0,0 represents the 0th TCI state of the 0th time instance corresponding to the 0th code point. TCI0,0,1 represents the 1st TCIstate of the 0th time instance corresponding to the 0th code point. TCI0,1,0 and TCI0,1,1 represent the two TCI states corresponding to the 1st time instance. Among them, TCI0,1,0 represents the 0th TCI state of the 1st time instance corresponding to the 0th code point. TCI0,1,1 represents the first TCI state of the first time instance corresponding to the 0th code point. TCI0,2,0 and TCI0,2,1 represent the two TCI states corresponding to the 2nd time instance. Among them, TCI0,2,0 represents the 0th TCI state of the 2nd time instance corresponding to the 0th code point. TCI0,2,1 represents the first TCI state of the 2nd time instance corresponding to the 0th code point. Among them, the number of beam information corresponding to each time instance is not limited to the two in Table 1, and can be 0, 1, 2, 3, 4, or even more. The multiple beam information corresponding to each time instance can also correspond to different transmission and receiving points (TRP) or different control resource set pool indexes (CORESETPoolIndex) or different cells. For example, a TRP identifier can be added, the 0th time instance corresponds to TPR0, and the 1st time instance corresponds to TRP1.
[0172] In some embodiments, one code point corresponds to K time instances, each of the K time instances corresponds to H first beam information, and the H first beam information represents information corresponding to the H first beams. K may be determined based on the fourth signaling. K is an integer greater than 1.
[0173] In some embodiments, the fourth signaling may be a MAC CE.
[0174] In some embodiments, the first information is also used to determine at least one of the following: the code point corresponding to the first beam information; the position of the time instance corresponding to the first beam information in K time instances; whether the first beam information corresponding to each time instance appears; the number H of first beams corresponding to each time instance; the position of the first beam information in H first beam information.
[0175] For example, the first information configures the beam information corresponding to the first time instance and indicates, through a bit field, whether the beam information corresponding to other time instances appears. For example, the first information may include a second identifier, which may also be referred to as an Ni identifier. The second identifier may indicate whether the first beam information corresponding to the time instance appears. The number of time instances K may be determined based on the number of time instances in which the beam information appears.
[0176] In some embodiments, if the beam information corresponding to the time instance determined by the first information does not appear, the beam information corresponding to the time instance is indicated based on other first information.
[0177] In some embodiments, if the beam information corresponding to the time instance determined by the first information does not appear, the beam information corresponding to the time instance is determined based on the beam information corresponding to the most recent time instance before the time instance indicated by the first information.
[0178] For example, the beam information may be a TCI state, and the first beam information of multiple time instances corresponding to a code point indicated by the first information may be shown in Table 2. Table 2 also includes a Pi identifier and a Ni identifier.
[0179] Table 2 shows the beam information of multiple time instances corresponding to the 0th code point. Among them, N0, N1, and N2 represent the second identifier in the first information, that is, the Ni identifier. For example, N0 indicates whether the beam information of the 0th time instance appears. N1 indicates whether the beam information of the 1st time instance appears. N2 indicates whether the beam information of the 2nd time instance appears. Except for some minor differences, P0, P1, P2 and TCI0,0,0, TCI0,0,1 in Table 2 have the same meaning as those in Table 1, and the present disclosure will not repeat them here. The minor differences include: in Table 2, if Ni indicates that the beam information corresponding to the time instance appears, Pi is an integer greater than 0; if Ni indicates that the beam information corresponding to the time instance does not appear, Pi is equal to 0 or Pi does not appear either. .
[0180] In some embodiments, a code point corresponds to a time instance, a time instance corresponds to P second beam information, and the P second beam information represents the information corresponding to the P second beams; the first information is also used to determine at least one of the following: the code point corresponding to the second beam information; the number P of second beams corresponding to one code point; the position of the second beam information in the P second beam information.
[0181] In some embodiments, the first information may be used to activate a beam at a time instance corresponding to a code point.
[0182] The first information may include multiple subscripts corresponding to the first beam information. Different subscripts are used to determine the code point corresponding to the first beam information, the position of the first beam information in the H first beam information, etc. For example, the beam information may be a TCI state, and the first subscript of the TCI is used to indicate the code point corresponding to the TCI. The second subscript indicates the TCI state number of the code point corresponding to the TCI. The first information may also include a first identifier, for example, the first identifier may be called a Pi identifier, which is used to determine the number of first beams corresponding to each time instance.
[0183] In some embodiments, since a code point corresponds to a time instance, the first information can determine the time instance corresponding to the second beam information by determining the code point corresponding to the second beam information. That is, the first information does not need to separately determine the time instance corresponding to the second beam information.
[0184] For example, the beam information may be a TCI state, and the beam information of a time instance corresponding to a code point indicated by the first information may be shown in Table 3. Table 3 also includes a Pi identifier.
[0185] Table 3 shows the beam information of a time instance corresponding to each code point. Among them, P0, P1, and P2 have the same meanings as P0, P1, and P2 in Table 1, and are not repeated here in this disclosure. TCI0,0 and TCI0,1 represent the TCI state corresponding to the 0th code point. TCI0,0 represents the 0th TCI state of the 0th code point. TCI0,1 represents the 1st TCI state of the 0th code point. TCI1,0 and TCI1,1 represent the TCI state corresponding to the 1st code point. TCI1,0 represents the 0th TCI state of the 1st code point. TCI1,1 represents the 1st TCI state of the 1st code point. TCI2,0 and TCI2,1 represent the TCI state corresponding to the 2nd code point. TCI2,0 represents the 0th TCI state of the 2nd code point. TCI2,1 represents the 1st TCI state of the 2nd code point.
[0186] In some embodiments, a position of the code point corresponding to the third beam information in the plurality of code points is based on a fifth signaling indication.
[0187] For example, the fifth signaling may be DCI.
[0188] In some embodiments, the first information includes third beam information for multiple time instances corresponding to multiple code points. At least one code point among the multiple code points corresponds to third beam information for multiple time instances. The first information can activate beam information for one or more time instances corresponding to each of the multiple code points. Each of the multiple code points corresponds to one or more time instances. When a code point corresponds to multiple time instances, for example, the 0th code point corresponds to Q time instances, and each of the Q time instances corresponds to W third beam information; the 1st code point corresponds to T time instances, and each of the T time instances corresponds to V third beam information. The fifth signaling is used to indicate the position of the code point corresponding to the third beam information among the multiple code points, that is, to indicate the code point to which the third beam information corresponds. The first information can be used to determine at least one of the following: the position of the time instance corresponding to the third beam information among the multiple time instances of its corresponding code point, the number of third beams corresponding to each time instance, and the position of the third beam information among the multiple third beam information. For example, for the 0th code point, the first information is used to determine at least one of the following: the position of the time instance corresponding to the third beam information in the Q time instances; the number W of third beams corresponding to each time instance; and the position of the third beam information in the W third beam information. For another example, for the 1st code point, the first information is used to determine at least one of the following: the position of the time instance corresponding to the third beam information in the T time instances; the number V of third beams corresponding to each time instance; and the position of the third beam information in the V third beam information. When a code point corresponds to a time instance, for example, the 0th code point corresponds to Z third beam information, the first information is used to determine at least one of the following: the number Z of third beam information corresponding to each code point; and the position of the third beam information in the Z third beam information.
[0189] In some embodiments, the first information includes third beam information for multiple time instances corresponding to multiple code points, where the number of code points may be multiple, and the number of bits of the fifth signaling is determined based on the number of code points, and the number of bits of the fifth signaling is greater than a first threshold. For example, the number of code points may be greater than 8, and accordingly, the number of bits of the fifth signaling needs to be greater than 3.
[0190] In some embodiments, the first information includes fourth beam information for multiple time instances corresponding to multiple code points, with at least one of the multiple code points corresponding to the fourth beam information for one time instance. The first information can activate the beam information for one time instance corresponding to each of the multiple code points. For example, the 0th code point corresponds to X pieces of fourth beam information; the 1st code point corresponds to Y pieces of fourth beam information. The fifth signaling is used to determine the position of the code point corresponding to the fourth beam information among the multiple code points, that is, to determine the code point to which the fourth beam information corresponds. The first information is also used to determine at least one of the following: the number of fourth beam information corresponding to each code point; the position of the fourth beam information within the multiple pieces of fourth beam information corresponding to that code point. For example, for the 0th code point, the first information is also used to determine at least one of the following: the number X of fourth beam information; the position of the fourth beam information within the X pieces of fourth beam information. For another example, for the 1st code point, the first information is also used to determine at least one of the following: the number Y of fourth beam information; the position of the fourth beam information within the Y pieces of fourth beam information. The number N of time instances corresponding to the fourth beam information is configured based on at least one of the first signaling, the second signaling, the third signaling, the first information, and the fifth signaling. The number of time instances corresponding to the fourth beam information is the same as the number of code points corresponding to the fourth beam information.
[0191] In some embodiments, N may be configured based on the first signaling or the third signaling, for example, the first signaling or the third signaling includes N. N may also be determined based on the second signaling or the fourth signaling, for example, by a bit field in the fourth signaling.
[0192] In some embodiments, N can be indicated based on the fifth signaling. For example, it can be indicated via an indication field in the fifth signaling. For example, the fifth signaling includes a first indication field that indicates the value of N. Alternatively, the value of N can be obtained by counting the code points indicated by the fifth signaling. Since each time instance corresponds to one code point, if the beam information corresponding to the time instance does not appear, the code point corresponding to the time instance is not counted.
[0193] In some embodiments, if N indicated by the fifth signaling is smaller than N determined by the first signaling, the second signaling, the third signaling, or the fourth signaling, it can be considered that the beam information corresponding to the time instances other than the N time instances indicated by the fifth signaling does not appear.
[0194] In some embodiments, if the number of time instances corresponding to the fourth beam information is determined based on the second signaling or the fourth signaling, the fourth signaling can also be used to determine whether the fourth beam information corresponding to each time instance appears. The number of time instances, N, is determined based on the number of time instances in which the fourth beam information appears. For example, if the number of time instances determined based on the first signaling or the third signaling is N+i, and the bit field in the fourth signaling indicates that the beam information corresponding to i of the time instances does not appear, the actual number of time instances indicated is N.
[0195] For example, the fourth beam information may be shown in Table 4. Table 4 also includes a Pi identifier and a Ni identifier.
[0196] The meanings of N0, N1, N2, P0, P1, and P2 in Table 4 can refer to N0, N1, N2, P0, P1, and P2 in the above Table 2, and the meanings of TCI0,0, and TCI0,1 can refer to TCI0,0, and TCI0,1 in Table 3, etc., and the present disclosure will not repeat them here.
[0197] In some embodiments, the name of the first information is not limited and may be, for example, "indication information", "beam information", etc.

[0227] In some embodiments, the above method may include the method of the above embodiments related to the communication system 100, the terminal 101, the network device 102, etc., which will not be repeated here.
[0228] The present disclosure also provides a communication method as follows:
[0229] In some embodiments, a terminal receives first information, where the first information is used to indicate beam information corresponding to multiple time instances, wherein the beam information includes TCI state, joint / DL TCI state, UL TCI state, and spationrelationinfo.
[0230] In some embodiments, how the application time corresponding to the beam information is indicated.
[0231] Method 1: Based on RRC configuration.
[0232] In some embodiments, RRC configures multiple application times corresponding to beams, and can directly give N time values, or RRC configures the value of N and the time interval value (time gap) between each two times.
[0233] Method 2: Based on RRC configuration or MAC CE activation.
[0234] In some embodiments, RRC configures multiple groups of parameters (the method includes any one of method 1), and MAC CE activates one of the groups.
[0235] In some embodiments, RRC gives the time gap and MAC CE indicates the value of N
[0236] In some embodiments, how the beams at multiple time points are indicated.
[0237] In some embodiments, a point in time may be equivalent to an instance in time.
[0238] Method 1: MAC CE
[0239] In some embodiments, the beams corresponding to N time points of a codepoint are activated.
[0240] In some embodiments, for example, each time point corresponds to one or more beams, and the beams may be DL TCI state, joint TCI state, or UL TCI state.
[0241] In some embodiments, if the RRC determines the N value, then the codepoint corresponds to at least N TCI states, that is, each time point corresponds to at least one TCI state, and the time point is determined according to the bit position of the MAC CE corresponding to the TCI state. The MAC CE also needs to indicate whether each time point corresponds to one or more TCI states.
[0242] In some embodiments, as shown in Table 1, TCI has three subscripts. The first subscript indicates the codepoint number, the second subscript indicates the time point, and the third subscript indicates whether the codepoint corresponds to the first or second TCI state at the time point.
[0243] In some embodiments, the Pi identifier corresponds to several TCI states, and / or when it corresponds to one, whether it is a DL or UL TCI state
[0244] In some embodiments, if the MAC CE determines the N value, the TCI state at the first time point must exist, and whether the TCI state exists at subsequent time points needs to be indicated by a bit field, thereby determining the value of N.
[0245] In some embodiments, as shown in Table 2, compared to Table 1, the main difference is the addition of a Ni field, which indicates whether the TCI state corresponding to the time value is indicated. If not indicated, there are two interpretations: one is that the subsequent MAC CE will indicate the next time; if not, only the most recent MAC CE will continue to indicate it; the other is that the TCI state at the subsequent time point remains unchanged.
[0246] In some embodiments, a beam corresponding to one time point of N codepoints may be activated, where the first codepoint corresponds to the first time point, the second codepoint corresponds to the second time point, and so on, as shown in Table 3.
[0247] Method 2: MAC CE+DCI.
[0248] Method 2-1:
[0249] In some embodiments, the MAC CE may activate one or more TCI states corresponding to multiple time points for one codepoint in the same manner as in method 1.
[0250] In some embodiments, the DCI indicates the codepoint, but since there are many beam combinations corresponding to different time points, the current 3-bit DCI may need to be increased.
[0251] Method 2-2:
[0252] In some embodiments, a MAC CE activates one or more TCI states corresponding to a codepoint at a time point.
[0253] In some embodiments, as shown in Table 3 below, each TCI has only two subscripts: the first corresponding to the codepoint, and the second corresponding to the TCI state of the codepoint. The MAC CE determines the N value similarly to Table 2, except that the TCI state subscripts are similar to those in Table 3.
[0254] In some embodiments, the DCI indicates a codepoint, and each time point corresponds to a codepoint, that is, the DCI needs to have N codepoint bit values.
[0255] In some embodiments, the value of N included in the DCI may be determined by RRC configuration or MAC CE.
[0256] In some embodiments, the value of N included in the DCI is indicated by a certain field of the DCI. If the value of N indicated in the DCI is smaller than the value of N determined by the RRC or MAC CE, it means that the beam information at the subsequent time point is not indicated.
[0257] 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.

Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. 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 ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
