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.

[0162] In some embodiments, a core network device can be a single device comprising one or more network elements, or it can be multiple devices or a group of devices, each comprising all or part of one or more network elements. Network elements can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC). Alternatively, a core network device refers to a network element with a specific function, such as an Access Management Function (AMF) or a Service Management Function (SMF).

[0163] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0164] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to a part thereof, but are not limited thereto.

[0165] The entities shown in Figure 1 are illustrative. The communication system may include all or some of the entities in Figure 1, or it may include other entities outside of Figure 1. The number and form of each entity are arbitrary. The connection relationship between the entities is illustrative. The entities may not be connected to each other or may be connected in any way. The connection may be direct or indirect, wired or wireless.

In order to know the power information of the terminal in a timely manner, the network device 102 will make the terminal 101 report PHR periodically or in the form of event triggering. The above reporting method will cause the terminal 101 to report PHR information more frequently, resulting in additional resource waste, especially in the application of AI technology.

[0168] With the continuous development of wireless communication technology, deploying AI technology on the base station side has become the evolutionary direction of cellular mobile communication. In scenarios where AI technology is applied, PHR prediction can be performed based on AI. However, frequent PHR reporting by terminal 101 can lead to unnecessary resource waste. Therefore, it is necessary to enhance or improve the traditional PHR reporting methods and systems.

[0169] Figure 2 is an interactive schematic diagram illustrating a method for sending and receiving indication information according to an embodiment of the present disclosure. As shown in Figure 2, this disclosure relates to a method for sending and receiving indication information, the method comprising:

[0170] In step S2101, network device 102 sends first instruction information to terminal 101.

[0171] In some embodiments, the first indication information can be sent via a Radio Resource Control (RRC) message.

[0172] In some embodiments, the first indication information is used to instruct terminal 101 to disable the reporting of Power Headroom Report (PHR).

[0173] Optionally, the first instruction information may instruct terminal 101 to cancel the reporting of one or more specific PHRs, or instruct terminal 101 to cancel the reporting of all PHRs.

[0174] In some embodiments, the PHR indicated by the first indication information includes some or all of the PHRs that have been configured or defined by the terminal 101. In this embodiment, the first indication information is used to instruct the terminal 101 to cancel some or all of the configured or defined PHRs.

[0175] Optionally, the PHR that has been configured or defined on terminal 101 is an existing PHR, which can be referred to in the relevant protocol description. For example, the PHR that has been configured or defined on terminal 101 includes: PHR reporting by terminal 101 in the form of periodic or event-triggered reporting.

[0176] In some embodiments, the PHR configured or defined by terminal 101 includes at least one of the following:

[0177] Periodic PHR;

[0178] The PHR is based on the first event, where the first event is some or all of all the events that trigger the PHR.

[0179] Optionally, network device 102 can configure terminal 101 to periodically report PHR, and can configure the period for sending PHR.

[0180] Optionally, PHR can also be event-triggered or condition-triggered, where the triggering event or triggering condition can include various factors, such as: changes in path loss exceeding a set value, RRC reconfiguration, the existence of a new transmission, etc. All possible triggering events or triggering conditions can be defined through protocol definitions or network configuration.

[0181] Optionally, the first event can be some or all of all triggering events. In one example, the first event is a specific triggering event, and the first indication information can instruct the terminal to cancel a PHR triggered based on a specific event, such as an RRC reconfiguration; or, for example, a new transmission occurring. In another example, the first event is all triggering events, and the first indication information can instruct the terminal to cancel all PHRs triggered based on these events.

[0182] In some examples, the first instruction information may instruct terminal 101 to cancel the reporting of some PHRs. For example, instructing terminal 101 to cancel the reporting of periodic PHRs, and / or instructing terminal 101 to cancel the reporting of all event-triggered PHRs. Another example is instructing terminal 101 to cancel the reporting of periodic PHRs, and / or instructing terminal 101 to cancel the reporting of PHRs triggered by a first event. Yet another example is instructing terminal 101 to cancel the reporting of some or all event-triggered PHRs.

[0183] In some embodiments, for the PHR cancelled as described above, the type of the PHR is at least one of the following:

[0184] Type 1: PHR corresponding to the uplink shared channel (SCH);

[0185] Type 2: PHR corresponding to the uplink control channel (SCH) and physical uplink control channel (PUCCH) in multi-connection state;

[0186] Type 3: PHR corresponding to the probe reference signal SRS.

[0187] In this embodiment, the PHR that can be canceled from being reported via the first instruction information can be any one or more of the above PHR types.

[0188] In Type 1, PHR is the difference between the nominal UE maximum transmit power and the estimated power of UL-SCH transmission in each activated serving cell. The nominal UE maximum transmit power can be determined based on the maximum configured power.

[0189] In Type 2, PHR is the difference between the nominal maximum transmit power of the UE and the estimated power of the UL-SCH and PUCCH transmit power on a special cell (SpCell) of another MAC entity (such as an e-UTRA MAC entity only in EN-DC, NE-DC, and NGEN-DC scenarios).

[0190] In Type 3, PHR is the difference between the nominal maximum transmit power of the UE and the estimated transmit power of the SRS for each active serving cell.

[0191] In some embodiments, network device 102 may send one or more first indication messages, wherein each first indication message is used to indicate the cancellation of a PHR report.

[0192] Optionally, network device 102 sends multiple RRC messages, each carrying a first indication information. Each RRC message or each first indication information corresponds to a PHR, so that each RRC message can indicate whether to cancel the reporting of the corresponding PHR through its carried first indication information. For example, the first indication information carried by the first RRC message indicates whether to cancel the reporting of periodic PHRs, the first indication information carried by the second RRC message indicates whether to cancel the reporting of all event-triggered PHRs, and the first indication information carried by the third RRC message indicates whether to cancel the reporting of PHRs triggered by a first event.

[0193] Optionally, network device 102 can carry multiple first indication messages by sending a single RRC message, and the time domain locations of the multiple first indication messages can be different. Each first indication message can be used to indicate the cancellation of the reporting of a corresponding PHR.

[0194] In some embodiments, the first indication information includes one or more fields, wherein each field is used to indicate the cancellation of the reporting of at least one PHR.

[0195] Optionally, network device 102 may send the first indication information via an RRC message such as RRC configuration information. The first indication information includes different fields to indicate whether to cancel the corresponding PHR reporting.

[0196] In one example, the first indication information includes at least one of a first field, a second field, and a third field; wherein the first field is used to indicate the cancellation of all PHR reporting, the second field is used to indicate the cancellation of periodic PHR reporting, and the third field is used to indicate the cancellation of PHR reporting triggered by the first event.

[0197] In this example, the first field could be the `disablePHRreprorting` field added to the RRC configuration information, used to indicate the cancellation of all PHR reporting. The second field could be the `disablephr-PeriodicTimer` field added to the RRC configuration information, used to indicate the cancellation of periodic PHR reporting. The third field could be the `disablenewtransmission` field added to the RRC configuration information, used to indicate the cancellation of PHR reporting triggered by the first event, where the first event is the existence of a new transmission.

[0198] In some embodiments, the first indication information includes an information field, which, when corresponding to different values, is used to indicate the cancellation of the reporting of at least one PHR.

[0199] Optionally, network device 102 may send the first indication information via an RRC message, such as in RRC configuration information.

[0200] Optionally, the information field may include one or more bits.

[0201] In one example, the information field satisfies one of the following:

[0202] When the information field is set to the first value, it indicates that all PHR reports should be cancelled.

[0203] The information field is set to the second value, indicating that periodic PHR reporting should be cancelled;

[0204] The information field is set to the third value, indicating that the reporting of the PHR triggered by the first event is cancelled;

[0205] The information field is the fourth value, indicating the cancellation of periodic and first-event triggered PHR reporting.

[0206] In this example, the information field consists of 2 bits. Referring to Table 1-1, the first value can be 00, the second value can be 01, the third value can be 10, and the fourth value can be 11. The first event can be RRC reconfiguration.

[0207] Table 1-1

[0208] In some embodiments, terminal 101 receives first indication information sent by network device 102 to learn about the cancellation of some or all PHR reports.

[0209] In step S2102, network device 102 predicts PHR based on an AI model.

[0210] In some embodiments, network device 102 can pre-train the AI ​​model to obtain a converged AI model, and then predict the PHR based on the AI ​​model. In related technologies, the PHR of a terminal is calculated based on base station resource allocation information and the terminal's own algorithm. In this embodiment of the present disclosure, network device 102 can predict the PHR of the terminal through the AI ​​model to reduce the reporting of terminal PHR, thereby reducing unnecessary signaling overhead and resource waste.

[0211] In some embodiments, the input to the AI ​​model can be historical data, i.e., the network device 102 obtains the predicted PHR based on the historical data input by the AI ​​model.

[0212] Optionally, historical data may include historical PHRs reported by different terminals 101. Each terminal 101 may report historical PHRs under different channel conditions and / or historical PHRs under different allocated resources. The allocated resources may be, for example, allocated resource blocks (RBs), or, for example, a number of different allocated RBs.

[0213] Optionally, the historical data may also include the reference signal received power (RSRP) or reference signal received quality (RSRQ) reported by the terminal 101.

[0214] In some embodiments, network device 102 can obtain a predicted PHR based on scheduling requirements, such as when network device 102 needs to perform closed-loop power control or allocate reasonable channel resources, it can predict the PHR based on AI models and historical data.

[0215] In step S2103, network device 102 sends a second instruction message to terminal 101.

[0216] In some embodiments, the second instruction information is used to instruct terminal 101 to restart PHR reporting.

[0217] In some embodiments, network device 102 may send the second indication information via RRC message or Downlink Control Information (DCI).

[0218] In some embodiments, when the network device 102 determines that the uplink channel quality of the terminal 101 is lower than a quality threshold, it executes step S2103, sending second indication information to the terminal 101 whose uplink channel quality is lower than the quality threshold. The network device 102 can obtain the uplink channel quality based on the reception of uplink signals.

[0219] In some embodiments, network device 102 may issue a second instruction message when there is a need to calibrate an AI model.

[0220] Optionally, the second indication information can be used to instruct terminal 101 to perform low-density PHR reporting. For example, in order to achieve calibration on the network device 102 side within a certain period of time, terminal 101 may be allowed to perform low-density PHR reporting. Here, "low density" refers to a reporting density lower than that of existing protocols or configured PHR reporting.

[0221] In some embodiments, network device 102 is configured to re-report relevant parameters of PHR.

[0222] In one example, network device 102 configures or instructs terminal 101 to re-report relevant parameters of the PHR by sending new signaling. This new signaling can be sent synchronously with the second instruction information, or before or after the second instruction information is sent.

[0223] In another example, network device 102 configures or instructs terminal 101 to re-report relevant parameters of PHR via second instruction information.

[0224] The second instruction information includes at least one of the following:

[0225] Restart the corresponding reporting cycle for PHR reporting;

[0226] Restart PHR reporting for the corresponding number of reporting times.

[0227] In this example, network device 102 can be configured or indicated to report a number greater than or equal to 1. When the configured or indicated reporting number is equal to 1, the restarted PHR reporting is a one-time event; that is, after terminal 101 performs one re-reporting of the PHR, it will not report the PHR again until network device 102 issues another command to start reporting the PHR. When the configured or indicated reporting number is greater than 1, terminal 101 can stop reporting the PHR after the corresponding number of re-reportings until network device 102 issues another command to start reporting the PHR.

[0228] In this example, network device 102 can configure or indicate that the reporting period is greater than a period threshold. This period threshold can be determined based on a PHR reporting period defined or configured in the protocol, i.e., based on the existing PHR period. For example, the period threshold is a PHR period configured by network device 102. In related technologies, terminal 101 can report PHRs based on this PHR period. In this embodiment of the present disclosure, the periodic PHR reporting corresponding to this PHR period can be canceled based on the first indication information. Optionally, network device 102 can set a longer reporting period by adjusting the phr-PeriodicTimer parameter in the relevant PHR reporting. When the reporting period is greater than the period threshold, terminal 101 can perform low-density PHR reporting.

[0229] In some embodiments, relevant parameters for re-reporting PHR are defined or preset through the protocol.

[0230] In one example, the reporting cycle and / or number of reports corresponding to restarting PHR reporting are defined by the protocol or preset by the terminal.

[0231] In this example, the terminal may have a preset low-density reporting mode or low-density reporting capability for re-reporting PHR. The parameters corresponding to the low-density reporting mode or low-density reporting capability can be defined by the protocol or preset by the terminal. When the terminal 101 receives a request from the base station to activate the PHR low-density reporting mode, such as when it receives the second indication information, the terminal 101 can re-report according to the preset low-density reporting mode, that is, re-report according to the reporting cycle and / or reporting number of the low-density reporting mode.

[0232] In this example, the reporting cycle and / or number of reports for the low-density reporting mode may include:

[0233] The number of reports is greater than or equal to 1. When the number of reports is equal to 1, the restarted PHR report is a one-time event; that is, after terminal 101 re-reports the PHR, it will not report the PHR again until network device 102 issues another command to start reporting the PHR. When the number of reports is greater than 1, such as N, terminal 101 can re-report the PHR N times and then stop reporting the PHR until network device 102 issues another command to start reporting the PHR.

[0234] The reporting period is greater than the period threshold. This period threshold can refer to the PHR reporting period that has been defined or configured in the protocol. If the reporting period is greater than the period threshold, a longer reporting period can be started during the re-reporting of PHR, resulting in low-density reporting.

[0235] In some embodiments, terminal 101 receives a second indication message sent by network device 102 to know when to re-report PHR.

[0236] In step S2104, terminal 101 re-reports PHR to network device 102 based on the second instruction information.

[0237] In some embodiments, terminal 101 re-reports PHR based on the indication of the second indication information and the reporting period and / or reporting number configured or indicated in the second indication information.

[0238] In some embodiments, the terminal 101 re-reports the PHR based on the instruction of the second instruction information and the reporting period and / or reporting number defined by the protocol or preset by the terminal.

[0239] In some embodiments, network device 102 receives the PHR re-reported by the terminal and may execute step S2105.

[0240] In step S2105, network device 102 calibrates the AI ​​model based on the re-reported PHR.

[0241] In some embodiments, the PHR predicted by the AI ​​model may be biased. To ensure the accuracy of the AI ​​model prediction, the network device 102 may perform some calibration.

[0242] In some embodiments, network device 102 can use the PHR re-reported by terminal 101 as the true value to calibrate the AI ​​model. For example, based on the difference between the PHR predicted by the AI ​​model and the true value, such as when the predicted value is large compared to the actual value, network device 102 can adjust the parameters of the AI ​​model to improve the reliability of the AI ​​model.

[0243] In some embodiments, network device 102 may perform AI model calibration at certain time intervals, or perform AI model calibration at appropriate times according to scheduling needs and scenario changes.

[0316] In some embodiments, other optional implementations may be described before or after the specification corresponding to FIG4c.

[0317] In this embodiment of the disclosure, the base station can disable the existing PHR reporting conditions of the terminal through signaling, and can indicate different conditions for canceling PHR reporting through multiple signaling messages or bit information. Furthermore, when the base station predicts the terminal's power margin PHR based on AI, it can allow the terminal to perform low-density reporting in order to obtain calibration within a certain time. To facilitate understanding of this embodiment of the disclosure, some examples are listed below:

[0318] Example 1:

[0319] The base station can cancel the existing PHR reporting conditions of the terminal through signaling.

[0320] In one embodiment, the base station can send a signaling message to the terminal, such as sending a relevant message via RRC, to allow the terminal to cancel the periodic reporting of PHR and / or event-triggered reporting.

[0321] In another embodiment, multiple messages can be sent to instruct the cancellation of periodic reporting of terminal PHR, and to instruct the cancellation of some or all event-triggered reporting.

[0322] For example, in one embodiment, the base station adds the following to the RRC configuration information:

[0323] disable PHRreprorting, and or

[0324] disablephr-PeriodicTimer, and or

[0325] Information such as disablenewtransmission can be used to cancel the corresponding triggering conditions.

[0326] Example 2:

[0327] The base station can cancel the existing PHR reporting conditions of the terminal through signaling.

[0328] In one embodiment, the conditions for canceling PHR reporting can be indicated using bit information. As shown in Table 1-2, the conditions for canceling PHR reporting can be indicated using 2 bits of information.

[0329] Table 1-2

[0330] Example 3:

[0331] When the base station predicts the power headroom (PHR) of the terminal based on AI, it allows the terminal to report at a low density in order to obtain calibration on the base station side within a certain period of time.

[0332] In one embodiment, when a base station detects that the uplink channel quality of a terminal is lower than a certain value, it can instruct the terminal to perform low-density PHR reporting via signaling.

[0333] In one embodiment, based on Example 1 or Example 2, the base station can also request the terminal to restart PHR reporting via signaling. This PHR reporting can be a one-time event, or the base station can define a reporting period and number of times N. After completing N reports according to the defined reporting period, no further reporting is performed until the terminal receives the next signaling from the base station requesting the restart of PHR reporting.

[0334] In another embodiment, based on Example 1 or Example 2, the base station may also utilize the phr-PeriodicTimer in the existing PHR reporting to set a longer reporting period.

[0335] Example 4:

[0336] The terminal has a preset low-density reporting mode. When it receives a request from the base station to activate the PHR low-density reporting mode, it reports according to the preset low-density reporting mode. The low-density reporting mode may include:

[0337] Report once, or

[0338] The terminal completes N reports according to the established reporting cycle. After completing all reports, no further reports are made until the terminal receives a signal from the base station requesting the next PHR reporting.

[0339] The reporting cycle has been lengthy.

[0340] Example 5:

[0341] The PHR that is canceled or restarted in the above example can be applied to the following three types:

[0342] In Type 1, PHR is the difference between the nominal maximum transmit power of the UE in each active serving cell and the estimated power of the UL-SCH transmission. This type is for the uplink shared channel.

[0343] In Type 2, PHR is the difference between the nominal maximum transmit power of the UE and the estimated power transmitted on the UL-SCH and PUCCH on the SpCell of another MAC entity (such as an e-UTRA MAC entity only in EN-DC, NE-DC, and NGEN-DC scenarios). This type targets the uplink shared channel and control channel in multi-connectivity states.
