Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a communication method and related apparatus. Background Technology

[0002] Event-triggered measurement result reporting refers to a terminal device reporting the corresponding measurement result to the network device when an event occurs. However, if the service beam between the network device and the terminal device changes after the event occurs, and the terminal device continues to report the corresponding measurement result, the validity of this measurement result is low, leading to a waste of reporting resources. Summary of the Invention

[0003] This application provides a communication method and related apparatus for reducing the waste of reporting resources.

[0004] Firstly, this application provides a communication method. This method is executed by a terminal device, or it may be executed by a chip, baseband chip, modem chip, system-on-chip (SoC) chip containing a modem core, system-in-package (SIP) chip, communication module, chip system, processor, logic module, or software within the terminal device. In this application, the term "terminal device" can refer to the terminal device itself, or to the chip, communication module, integrated circuit, processor, logic module, or software within the terminal device used to implement the communication method provided in this application; no specific limitation is made in this application.

[0005] First, the terminal device sends a first uplink signaling to the network device. This first uplink signaling can be used to request the network device to schedule a first uplink resource for the terminal device, wherein the first uplink resource is used to carry the terminal device's event-triggered measurement results and / or to indicate the occurrence of an event; or, the first uplink signaling can be used to notify the network device that the event-triggered measurement results will be carried on the first uplink resource and / or to indicate the occurrence of an event. The terminal device receives beam indication signaling from the network device, which indicates the terminal device's serving beam. If a first condition is met, the terminal device does not send the event-triggered measurement results on the first uplink resource.

[0006] In the above technical solution, if the first condition is met, the terminal device will not send event-triggered measurement results on the first uplink resource. This reduces unnecessary reporting of event-triggered measurement results, improves the efficiency of reporting measurement results, and saves reporting resources.

[0007] Optionally, the first uplink signaling can be replaced with other descriptions, such as the first uplink signaling being used to request the network device to schedule the second uplink signaling, and the second uplink signaling being used to carry the event-triggered measurement results; or, the first uplink signaling being used to instruct the network device that the terminal device needs to report the event-triggered measurement results; or, the first uplink signaling being used to indicate that an event has occurred, which refers to a specific event that triggered the reporting of measurement results; or, the first uplink signaling being used to request the network device to schedule uplink resources to carry the event-triggered measurement results.

[0008] Optionally, the beam indication signaling can be replaced with other descriptions, such as the beam indication signaling being used to indicate the service beam of the switching terminal device, or the beam indication signaling being used to indicate a change in the service beam between the network device and the terminal device, or the beam indication signaling being used to indicate a change in the service beam of the terminal device, or the beam indication signaling being used to indicate that a new beam is used as the service beam.

[0009] In the first aspect described above, the terminal device not sending event-triggered measurement results on the first uplink resource can be replaced with other descriptions. For example, the terminal device does not send event-triggered measurement results, or the terminal device discards event-triggered measurement results, or the terminal device clears event-triggered measurement results, or the terminal device ignores the first scheduling signaling from the network device, wherein the first scheduling signaling is used to indicate or schedule the first uplink resource, or the terminal device does not send event-triggered measurement results on the first uplink resource indicated or scheduled by the first scheduling signaling. Optionally, on the first uplink resource indicated or scheduled by the first scheduling signaling, there is no multiplexing of hybrid automatic repeat request-acknowledgment (HARQ-ACK) messages, transport blocks, or traditional channel state information (CSI) measurement results. The traditional CSI measurement results can also be referred to as non-event-triggered reporting, or traditional CSI reporting, or CSI reporting configured by CSI-ReportConfig, or CSI reporting triggered or configured by network devices, or CSI reporting without event information configured by LTM-CSI-ReportConfig, or CSI reporting without event-related information in CSI-ReportConfig, or CSI reporting that does not contain event information. The naming of these terms is not limited in the embodiments of this application.

[0010] In the first aspect above, the aforementioned event-triggered measurement results can be alternatively described as a measurement result report, an event-triggered report, an event-triggered or UE-initiated measurement result report, an event-triggered or UE-initiated CSI report, a CSI report, an event-triggered or UE-initiated beam measurement result report, a beam measurement result report, an event-triggered or UE-initiated interference measurement report, or an interference measurement report, a measurement report, or an event-related measurement result, which is not limited in this application.

[0011] Based on the first aspect, in one optional implementation, the terminal device sends a first uplink signaling to the network device via a second uplink resource. The first uplink signaling is used to request the network device to schedule the first uplink resource for the terminal device and / or to indicate the occurrence of an event. The first uplink resource is used to carry measurement results triggered by the event. One possible interpretation is that the second uplink resource is a periodic uplink resource (e.g., a PUCCH resource or a PUSCH resource), and the terminal device sends the first uplink signaling on one or more or all of the cycles of the second uplink resource. Next, the network device receives the first uplink signaling and sends a first scheduling signaling to the terminal device; correspondingly, the terminal device receives the first scheduling signaling from the network device. The first scheduling signaling is used to indicate or schedule the first uplink resource. Then, the network device sends a beam indication signaling to the terminal device; correspondingly, the terminal device receives the beam indication signaling from the network device. The first condition in this application includes at least one of the following:

[0012] The terminal device receives beam indication signaling after a first duration following the receipt of the first scheduling signaling and before the first uplink resource;

[0013] The terminal device receives beam indication signaling a first duration after receiving the first scheduling signaling, and the first uplink resource is located a second duration after the terminal device receives the beam indication signaling;

[0014] After sending the first uplink signaling, the terminal device receives beam indication signaling after a first duration following the receipt of the first scheduling signaling and before the first uplink resource.

[0015] After the terminal device sends the first uplink signaling, and after a first duration following the receipt of the first scheduling signaling, it receives the beam indication signaling, and the first uplink resource is located after a second duration following the receipt of the beam indication signaling by the terminal device.

[0016] In this way, when the terminal device receives the first scheduling signaling first and then the beam indication signaling, it can realize that it does not need to send the event-triggered measurement results on the first uplink resource indicated by the first scheduling signaling, thereby reducing the overhead of uplink resources.

[0017] In this process, the network device indicates the first uplink resource, and the terminal device obtains information about the time-domain and frequency-domain resources within the first uplink resource. Therefore, the description "before the first uplink resource" can be replaced with "before the time-domain resources within the first uplink resource," "before the symbol where the first uplink resource is located," or "before the first uplink resource scheduled or indicated by the first scheduling signaling."

[0018] The description of "receiving beam indication signaling" can be replaced with "the symbol where the beam indication signaling is received", "when the beam indication signaling is received", or "the moment the beam indication signaling is received".

[0019] The phrase "after the terminal device receives the first scheduling signaling for a first duration" can be understood as "after the terminal device receives the first scheduling signaling and a first duration has elapsed".

[0020] The phrase "after the second duration after the terminal device receives the beam indication signaling" can be understood as "the moment the terminal device receives the beam indication signaling and after the second duration has elapsed".

[0021] Optionally, the first condition above can be replaced with other descriptions. For example, the first condition may include at least one of the following:

[0022] After receiving the first scheduling signaling, and before receiving the first uplink resource, the terminal device receives the beam indication signaling;

[0023] After receiving the first scheduling signaling, the terminal device receives the beam indication signaling, and the first uplink resource is located after the terminal device receives the beam indication signaling;

[0024] After sending the first uplink signaling, the terminal device receives the beam indication signaling after receiving the first scheduling signaling and before receiving the first uplink resource;

[0025] After sending the first uplink signaling, and after receiving the first scheduling signaling, the terminal device receives the beam indication signaling, and the first uplink resource is located after the time when the terminal device receives the beam indication signaling.

[0026] Based on the first aspect, in one optional implementation, the terminal device sends a first uplink signaling to the network device via a second uplink resource. The first uplink signaling is used to request the network device to schedule the first uplink resource for the terminal device and / or to indicate the occurrence of an event. The first uplink resource is used to carry measurement results triggered by the event. One possible interpretation is that the second uplink resource is a periodic uplink resource (e.g., a PUCCH resource or a PUSCH resource), and the terminal device sends the first uplink signaling on one or more or all of the cycles of the second uplink resource. Next, the network device receives the first uplink signaling and sends beam indication signaling to the terminal device; correspondingly, the terminal device receives the beam indication signaling from the network device. Then, the network device sends a first scheduling signaling to the terminal device; correspondingly, the terminal device receives the first scheduling signaling from the network device. The first scheduling signaling is used to indicate or schedule the first uplink resource. Therefore, the first condition in this application includes at least one of the following:

[0027] The terminal device receives beam indication signaling after the third duration of sending the first uplink signaling and before the fourth duration;

[0028] After a third duration following the transmission of the first uplink signaling, the terminal device receives a beam indication signaling but does not receive the first scheduling signaling.

[0029] The terminal device receives beam indication signaling after a third time interval and before a fourth time interval after sending the first uplink signaling, but does not receive the first scheduling signaling;

[0030] After a third duration of sending the first uplink signaling, the terminal device receives the beam indication signaling, and after a fifth duration of receiving the beam indication signaling, it receives the first scheduling signaling.

[0031] The terminal device receives beam indication signaling after a third duration and before a fourth duration after sending the first uplink signaling, and receives the first scheduling signaling after a fifth duration after receiving the beam indication signaling;

[0032] The terminal device receives beam indication signaling three time intervals after sending the first uplink signaling, and receives the first scheduling signaling five time intervals after receiving the beam indication signaling.

[0033] The terminal device receives beam indication signaling after a third duration and before a fourth duration after sending the first uplink signaling, and receives the first scheduling signaling before a fifth duration after receiving the beam indication signaling.

[0034] The phrase "after the third duration of the first uplink signaling sent by the terminal device and before the fourth duration" can be understood as "after the terminal device has sent the first uplink signaling and experienced the third duration, and before the time when the first uplink signaling was sent plus the fourth duration".

[0035] The phrase "after the terminal device receives the beam indication signaling for the fifth time period" can be understood as "the moment the terminal device receives the beam indication signaling and after the fifth time period has elapsed".

[0036] The phrase "before the terminal device receives the beam indication signaling for the fifth duration" can be understood as "the time when the terminal device receives the beam indication signaling plus the time when the fifth duration is located".

[0037] In this way, when the terminal device receives the beam indication signaling first and then the first scheduling signaling, it can realize that it does not need to send the event-triggered measurement results on the first uplink resource indicated by the first scheduling signaling, thereby reducing the overhead of uplink resources.

[0038] Optionally, the first condition above can be replaced with other descriptions. For example, the first condition may include at least one of the following:

[0039] After sending the first uplink signaling, the terminal device receives the beam indication signaling;

[0040] After sending the first uplink signaling, the terminal device receives the beam indication signaling but does not receive the first scheduling signaling;

[0041] After sending the first uplink signaling, the terminal device receives the beam indication signaling, and after receiving the beam indication signaling, it receives the first scheduling signaling.

[0042] Based on the first aspect, in an optional implementation, if the first condition is met, the terminal device may ignore the first scheduling signaling, thereby avoiding the terminal device from sending event-triggered measurement results on the first uplink resource indicated by the first scheduling signaling.

[0043] Based on the first aspect, in one optional implementation, the terminal device sends a first uplink signaling to the network device via a second uplink resource. The first uplink signaling is used to notify the network device that an event-triggered measurement result will be carried on the first uplink resource and / or to indicate the occurrence of an event. The first uplink resource is used to carry the event-triggered measurement result. Optionally, before the terminal device sends the first uplink signaling to the network device, the network device pre-configures and activates the first uplink resource for the terminal device, or the network device pre-configures an inactive or activated first uplink resource for the terminal device. One possible interpretation is that the second uplink resource is a periodic uplink resource (e.g., a PUCCH resource or a PUSCH resource), and the terminal device sends the first uplink signaling on one or more or all of the cycles of the second uplink resource. The first uplink resource is associated with a specific transmission timing of the second uplink resource. The first uplink signaling can be sent on the second uplink resource only if an event-triggered measurement result exists; alternatively, the terminal device can also send the first uplink signaling on the second uplink resource. This first uplink signaling indicates whether an event-triggered measurement result needs to be sent via the second uplink resource. In other words, the first uplink signaling indicates the existence of an event-triggered measurement result. Next, the network device sends beam indication signaling to the terminal device, and the terminal device receives the beam indication signaling from the network device. Therefore, the first condition in this application includes at least one of the following:

[0044] The terminal device receives beam indication signaling six hours after sending the first uplink signaling and before the first uplink resource;

[0045] The terminal device receives beam indication signaling six hours after sending the first uplink signaling, and the first uplink resource is located seven hours after the terminal device receives the beam indication signaling.

[0046] In this way, the terminal device can choose not to send event-triggered measurement results on the first uplink resource, thereby reducing the overhead of the first uplink resource.

[0047] Optionally, the first condition above can be replaced with other descriptions. For example, the first condition may include at least one of the following:

[0048] After sending the first uplink signaling and before the first uplink resource, the terminal device receives the beam indication signaling;

[0049] After sending the first uplink signaling, the terminal device receives the beam indication signaling, and the first uplink resource is located after the terminal device receives the beam indication signaling.

[0050] Secondly, this application provides a communication method. This method is executed by a terminal device, or it may be executed by a chip, baseband chip, modem chip, SoC chip containing a modem core, SIP chip, communication module, chip system, processor, logic module, or software within the terminal device. In this application, the term "terminal device" can refer to the terminal device itself, or to the chip, communication module, integrated circuit, processor, logic module, or software within the terminal device used to implement the communication method provided in this application; no specific limitation is made in this application.

[0051] The terminal device sends a first uplink signaling message to the network device. Correspondingly, the network device receives the first uplink signaling message from the terminal device. The first uplink signaling message requests the network device to schedule a first uplink resource for the terminal device. This first uplink resource is used to carry event-triggered measurement results from the terminal device and / or to indicate the occurrence of an event; alternatively, the first uplink signaling message notifies the network device that event-triggered measurement results are carried on the first uplink resource and / or to indicate the occurrence of an event. If a second condition is met, the terminal device does not expect to receive the first scheduling signaling message or the beam indication signaling message. The first scheduling signaling message indicates the first uplink resource, and the beam indication signaling message indicates the serving beam of the terminal device.

[0052] In this application, if the second condition is met, the terminal device does not expect to receive the first scheduling signaling or beam indication signaling. This avoids the situation where beam indication signaling is received but the event condition is not met, yet the measurement result is still reported based on the event trigger, or where the measurement result is invalid, thus avoiding a waste of reporting resources.

[0053] Optionally, the first uplink signaling can be replaced with other descriptions, such as the first uplink signaling being used to request the network device to schedule the second uplink signaling, and the second uplink signaling being used to carry the event-triggered measurement results; or, the first uplink signaling being used to instruct the network device that the terminal device needs to report the event-triggered measurement results; or, the first uplink signaling being used to indicate that an event has occurred, which refers to a specific event that triggered the reporting of measurement results; or, the first uplink signaling being used to request the network device to schedule uplink resources to carry the event-triggered measurement results.

[0054] Optionally, the phrase "the terminal device does not expect to receive the first scheduling signaling or beam indication signaling" in this application can be replaced with "the terminal device does not receive the first scheduling signaling or beam indication signaling", or "the terminal device does not parse the first scheduling signaling or beam indication signaling", or "the terminal device ignores the first scheduling signaling or beam indication signaling".

[0055] Based on the second aspect, in one optional implementation, the terminal device sends a first uplink signaling to the network device via a second uplink resource. Then, the network device sends beam indication signaling to the terminal device, and correspondingly, the terminal device receives beam indication signaling from the network device. If a second condition is met, the terminal device does not expect to receive the first scheduling signaling. The second condition includes at least one of the following:

[0056] Before the terminal device receives the beam indication signaling for the eighth time period;

[0057] After the terminal device receives the beam indication signaling for the ninth time period and before the eighth time period;

[0058] Ten hours after the terminal device sends the first uplink signaling and before the eighth hour after receiving the beam indication signaling;

[0059] Nine hours after the terminal device receives the beam indication signaling, and without retransmitting or sending the first uplink signaling to the network device.

[0060] In this way, after receiving the beam indication signaling, the terminal device can avoid receiving the first scheduling signaling, and thus avoid sending event-triggered measurement results on the first uplink resource indicated by the first scheduling signaling.

[0061] Optionally, the second condition above can be replaced with other descriptions. For example, the second condition may include at least one of the following:

[0062] After the terminal device receives the beam indication signaling;

[0063] After the terminal device sends the first uplink signaling, and before it receives the beam indication signaling;

[0064] After the terminal device receives the beam indication signaling, it does not retransmit the first uplink signaling to the network device.

[0065] Based on the second aspect, in one optional implementation, the terminal device sends a first uplink signaling to the network device via a second uplink resource. Then, the network device sends a first scheduling signaling to the terminal device, and correspondingly, the terminal device receives the first scheduling signaling from the network device. If a second condition is met, the terminal device does not expect to receive beam indication signaling. The second condition includes at least one of the following:

[0066] Before the eleventh duration after the terminal device sends the first uplink signaling;

[0067] After the twelfth time period after the terminal device sends the first uplink signaling and before the eleventh time period;

[0068] After the terminal device sends the first uplink signaling, and before the first uplink resource;

[0069] After the terminal device sends the first uplink signaling for twelfth duration, and before the first uplink resource.

[0070] In this way, after receiving the first scheduling signaling, the terminal device can avoid receiving beam indication signaling, thereby preventing beam indication signaling from interfering with the terminal device's reporting of event-triggered measurement results.

[0071] Optionally, the above two conditions can be replaced with other descriptions. For example, the second condition may include at least one of the following:

[0072] After the terminal device sends the first uplink signaling;

[0073] After the terminal device sends the first uplink signaling, and before the first uplink resource.

[0074] In this process, the network device indicates the first uplink resource, and the terminal device obtains information about the time-domain and frequency-domain resources within the first uplink resource. Therefore, the description "before the first uplink resource" can be replaced with "before the time-domain resources within the first uplink resource," "before the symbol where the first uplink resource is located," or "before the first uplink resource scheduled or indicated by the first scheduling signaling."

[0075] The description of "receiving beam indication signaling" can be replaced with "the symbol where the beam indication signaling is received", "when the beam indication signaling is received", or "the moment the beam indication signaling is received".

[0076] The phrase "after the terminal device receives the first scheduling signaling for a first duration" can be understood as "after the terminal device receives the first scheduling signaling and a first duration has elapsed".

[0077] The phrase "after the second duration after the terminal device receives the beam indication signaling" can be understood as "the moment the terminal device receives the beam indication signaling and after the second duration has elapsed".

[0078] Thirdly, this application provides a communication method. This method is executed by a network device, or it may be executed by a chip, baseband chip, modem chip, SoC chip containing a modem core, SIP chip, communication module, chip system, processor, logic module, or software within the network device. In this application, the term "network device" can refer to the network device itself, or to the chip, communication module, integrated circuit, processor, logic module, or software within the network device used to implement the communication method provided in this application; no specific limitation is made in this application.

[0079] The network device receives a first uplink signaling from the terminal device. This first uplink signaling is used to request the network device to schedule first uplink resources for the terminal device and / or to indicate the occurrence of an event; alternatively, the first uplink signaling is used to notify the network device that an event-triggered measurement result is carried on the first uplink resources and / or to indicate the occurrence of an event. The first uplink resources are used to carry the event-triggered measurement result from the terminal device.

[0080] If the third condition is met, the network device will not send the first scheduling signaling or the beam indication signaling, wherein the first scheduling signaling is used to indicate the first uplink resource, and the beam indication signaling is used to indicate the serving beam of the terminal device.

[0081] In this application, by using the third condition, the network device reduces the transmission of the first scheduling signaling or beam indication signaling, thereby reducing unnecessary reporting of event-triggered measurement results, improving the efficiency of reporting measurement results, and saving reporting resources.

[0082] The first uplink signaling can be replaced with other descriptions, such as the first uplink signaling being used to request the network device to schedule the second uplink signaling, and the second uplink signaling being used to carry the event-triggered measurement results; or, the first uplink signaling being used to instruct the network device that the terminal device needs to report the event-triggered measurement results; or, the first uplink signaling being used to indicate that an event has occurred, which refers to a specific event that triggered the reporting of measurement results; or, the first uplink signaling being used to request the network device to schedule uplink resources to carry the event-triggered measurement results.

[0083] Based on the third aspect, in one optional implementation, the terminal device sends a first uplink signaling to the network device via a second uplink resource. Then, the network device sends a beam indication signaling to the terminal device, and correspondingly, the terminal device receives the beam indication signaling from the network device. If a third condition is met, the network device does not send the first scheduling signaling to the terminal device. The third condition includes at least one of the following:

[0084] Before the fifteenth time interval after the network device sends the beam indication signaling;

[0085] After the sixteenth time interval and before the fifteenth time interval following the transmission of beam indication signaling by the network device;

[0086] Seventeen hours after the network device receives the first uplink signaling, and fifteen hours before the beam indication signaling is sent;

[0087] Sixteen hours after the network device sends the beam indication signaling, and no retransmission or first uplink signaling is received from the terminal device.

[0088] The phrase "before the fifteenth time interval after the network device sends the beam indication signaling" can be understood as "before the time when the network device sends the beam indication signaling plus the time when the fifteenth time interval is located".

[0089] The phrase "after the sixteenth time period after the network device sends the beam indication signaling and before the fifteenth time period" can be understood as "after the sixteenth time period has elapsed since the network device sends the beam indication signaling and before the time when the beam indication signaling is sent plus the fifteenth time period".

[0090] The phrase "after the network device receives the first uplink signaling for seventeen hours" can be understood as "after the network device receives the first uplink signaling and seventeen hours have elapsed".

[0091] The phrase "after the sixteenth time period since the network device sent the beam indication signaling and no retransmission or first uplink signaling has been received from the terminal device" can be understood as "at the moment the network device sent the beam indication signaling and after the sixteenth time period, the network device did not retransmit or send the first uplink signaling to the terminal device that received it."

[0092] In this way, after receiving the beam indication signaling, the terminal device can avoid receiving the first scheduling signaling, thereby avoiding the terminal device from sending event-triggered measurement results on the first uplink resource indicated by the first scheduling signaling.

[0093] Optionally, the fifteenth duration can be configured by the network device, determined by the capabilities of the terminal device, or related to any one or more of the provisions in the protocol. For example, the fifteenth duration can be the minimum time interval between beam indication signaling and the first scheduling signaling configured by the network device. The fifteenth duration includes N time units, where N is an integer greater than or equal to 0. For example, this time unit can be an hour, minute, second, millisecond, microsecond, nanosecond, frame, subframe, slot, symbol, sampling time (Ts), or basic time unit (Tc), etc. Regarding the description of the sixteenth and seventeenth durations, the sixteenth duration includes M time units, where M is an integer greater than or equal to 0. Optionally, the sixteenth duration can be related to the time the terminal device processes the beam indication signaling; the seventeenth duration includes X time units, where X is an integer greater than or equal to 0. Optionally, the seventeenth duration can be related to the time the network device processes the first uplink signaling. The rest are similar to the description of the fifteenth duration above, and will not be repeated here.

[0094] Optionally, the third condition above can be replaced with other descriptions. For example, the third condition may include at least one of the following:

[0095] After the network device sends beam indication signaling;

[0096] After the network device receives the first uplink signaling, but before sending the beam indication signaling;

[0097] After the network device sends a beam indication signaling message, it does not receive the first uplink signaling message retransmitted by the terminal device.

[0098] Based on the third aspect, in one optional implementation, the terminal device sends a first uplink signaling to the network device via a second uplink resource. Then, the network device sends a first scheduling signaling to the terminal device, and correspondingly, the terminal device receives the first scheduling signaling from the network device. If a third condition is met, the network device does not send beam indication signaling to the terminal device. The third condition includes at least one of the following:

[0099] Before the network device receives the first uplink signaling for eighteen hours;

[0100] Nineteen hours after the network device receives the first uplink signaling and eighteen hours before the first uplink signaling;

[0101] Nineteen hours after the network device receives the first uplink signaling, and before the first uplink resource.

[0102] The phrase "before the eighteenth hour after the network device receives the first uplink signaling" can be understood as "before the time when the network device receives the first uplink signaling plus the time when the eighteenth hour is located".

[0103] The phrase "after the nineteenth duration and before the eighteenth duration when the network device receives the first uplink signaling" can be understood as "after the network device receives the first uplink signaling and has experienced the nineteenth duration, and before the time when the first uplink signaling is received plus the eighteenth duration".

[0104] The phrase "after the network device receives the first uplink signaling for nineteen hours and before the first uplink resource" can be understood as "at the moment the network device receives the first uplink signaling and after nineteen hours have elapsed".

[0105] In this context, the network device indicates the first uplink resource, and the terminal device obtains information about the time-domain and frequency-domain resources within the first uplink resource. Therefore, the description "before the first uplink resource" can be replaced with "before the time-domain resources in the first uplink resource" or "before the symbol containing the first uplink resource".

[0106] In this way, after receiving the beam indication signaling, the terminal device can avoid receiving the first scheduling signaling, thereby avoiding the terminal device from sending event-triggered measurement results on the first uplink resource indicated by the first scheduling signaling.

[0107] Optionally, the eighteenth duration can be configured by the network device, determined by the capabilities of the terminal device, or related to any one or more of the provisions in the protocol. For example, the eighteenth duration can be the maximum time interval between the first uplink signaling and the first scheduling signaling configured by the network device. For example, the nineteenth duration is related to the duration for the network device to process the first uplink signaling, or to the UE's RF capability for switching uplink and downlink, etc. The eighteenth duration includes N time units, where N is an integer greater than or equal to 0. For example, this time unit can be an hour, minute, second, millisecond, microsecond, nanosecond, frame, subframe, slot, symbol, sampling time (Ts), or basic time unit (Tc), etc. The nineteenth duration includes M time units, and the rest are similar to the description of the eighteenth duration above, and will not be repeated here.

[0108] Optionally, the third condition above can be replaced with other descriptions. For example, the third condition may include at least one of the following:

[0109] Before the network device receives the first uplink signaling;

[0110] After the network device receives the first uplink signaling, and before the first uplink resource.

[0111] In this context, the network device indicates the first uplink resource, and the terminal device obtains information about the time-domain and frequency-domain resources within the first uplink resource. Therefore, the description "before the first uplink resource" can be replaced with "before the time-domain resources in the first uplink resource" or "before the symbol containing the first uplink resource".

[0172] The present application will now be described with reference to the accompanying drawings. The terminology used in the embodiments section is for illustrative purposes only and is not intended to limit the scope of the application. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in this application are equally applicable to similar technical problems.

[0173] First, some of the nouns or terms used in this application will be explained, and these nouns or terms are also part of the content of the invention.

[0174] (1) The terms “system” and “network” in this application are used interchangeably. “Multiple” refers to two or more. “And / or” describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character “ / ” generally indicates that the related objects before and after are in an “or” relationship. “At least one of the following” or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, “at least one of A, B and C” includes A, B, C, AB, AC, BC or ABC. Unless otherwise specified, the ordinal numbers such as “first” and “second” mentioned in this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority or importance of multiple objects. Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0175] (2) In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly via the air interface or sending indirectly via the air interface from other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving directly from YY via the air interface or receiving indirectly from YY via the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0176] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0177] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0178] (3) Configuration and Pre-configuration: In this application, both configuration and pre-configuration are used. Configuration refers to the network device or server sending configuration information or parameter values ​​to the terminal device via messages or signaling, so that the terminal device can determine the communication parameters or resources for transmission based on these values ​​or information. Pre-configuration is similar to configuration; it can be parameter information or parameter values ​​pre-negotiated between the network device / server and the terminal device, parameter information or parameter values ​​specified by standard protocols for use by the base station / network device or terminal device, or parameter information or parameter values ​​pre-stored in the base station / server or terminal device. This application does not limit this.

[0179] It should be understood that these values ​​and parameters can change or be updated.

[0180] (4) In this application, “instruction” may include direct instruction and indirect instruction, and may also include explicit instruction and implicit instruction. When a certain instruction information is used to instruct A, it can be understood that the instruction information carries A, directly instructs A, or indirectly instructs A.

[0181] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a relationship between the other information and the information to be instructed; or it can indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon, for example, by using a pre-agreed (e.g., protocol-predefined) arrangement of various information to indicate specific information, thereby reducing instruction overhead to some extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed, and for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0182] (5) Terminal device: can be a wireless terminal device capable of receiving network device scheduling and instruction information. The wireless terminal device can be a device that provides voice and / or data connectivity to the user, or a handheld device with wireless connection function, or other processing device connected to a wireless modem.

[0183] Terminal devices can communicate with one or more core networks or the Internet via a radio access network (RAN). Terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones), computers, and data cards. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), tablets, and computers with wireless transceiver capabilities. Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station (MS), remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, subscriber station (SS), customer premises equipment (CPE), terminal, user equipment (UE), mobile terminal (MT), etc.

[0184] By way of example and not limitation, the terminal device in this application can also be a wearable device. Wearable devices, also known as wearable smart devices or smart wearable devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0185] Terminals can also be drones, robots, devices in device-to-device (D2D) communication, vehicles to everything (V2X) communication, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in telemedicine or telehealth services, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc.

[0186] Furthermore, terminal devices can also be terminal devices in communication systems evolved from fifth-generation (5G) communication systems (such as 5G Advanced or future communication systems) or in future public land mobile networks (PLMNs). For example, 5G Advanced or 6G networks can further expand the form and function of 5G communication terminals; 6G terminals include, but are not limited to, vehicles, cellular network terminals (integrating satellite terminal functions), drones, and Internet of Things (IoT) devices.

[0187] In this application, the aforementioned terminal device may also receive artificial intelligence (AI) services provided by the network device. Optionally, the terminal device may also have AI processing capabilities.

[0188] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, chip system, module, or control unit in the device or apparatus shown above; this application does not limit the specific application. In this application, when referring to a terminal device, it can refer to the terminal device itself, or to the chip, functional module, or integrated circuit in the terminal device that performs the method provided in this application; this application does not limit the specific application.

[0189] (6) Network equipment: This can be equipment within a wireless network. For example, network equipment can be a radio access network (RAN) node (or device) that connects terminal devices to the wireless network, and can also be called a base station. Currently, some examples of RAN equipment include: base station, evolved NodeB (eNodeB), gNB (gNodeB) in 5G communication systems, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wi-Fi) access point (AP), etc. In addition, in a network structure, network equipment can include central unit (CU) nodes, distributed unit (DU) nodes, or RAN equipment including CU nodes and DU nodes.

[0190] Optionally, RAN nodes can also be macro base stations, micro base stations, indoor stations, relay nodes, donor nodes, or radio controllers in cloud radio access network (CRAN) scenarios. RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0191] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be CUs, DUs, CUs (control plane, CP), CUs (user plane, UP), or radio units (RUs). CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), radio heads (RHs), or remote radio heads (RRHs).

[0192] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open access network (open RAN, O-RAN, or ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0193] Communication between access network devices and terminal devices follows a specific protocol layer structure. This protocol layer may include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer may include at least one of the following: radio resource control (RRC) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, media access control (MAC) layer, or physical (PHY) layer, etc. The user plane protocol layer may include at least one of the following: service data adaptation protocol (SDAP) layer, PDCP layer, RLC layer, MAC layer, or physical layer, etc.

[0194] The correspondence between network elements and their achievable protocol layer functions in the ORAN system can be found in Table 1 below.

[0195] Table 1

[0197] Network devices can be other devices that provide wireless communication functions for terminal devices. The embodiments of this application do not limit the specific technology or form of the network device. For ease of description, this application is not limiting.

[0198] Network equipment may also include core network equipment, such as the Mobility Management Entity (MME), Home Subscriber Server (HSS), Serving Gateway (S-GW), Policy and Charging Rules Function (PCRF), and Public Data Network Gateway (PDN gateway or P-GW) in 4th generation (4G) networks; and access and mobility management function (AMF), user plane function (UPF), or session management function (SMF) in 5G networks. Furthermore, this core network equipment may also include other core network equipment in 5G networks and next-generation networks of 5G networks.

[0199] In this application, the aforementioned network equipment may also have network nodes with AI capabilities, which can provide AI services to terminals or other network equipment. For example, it can be an AI node, computing power node, RAN node with AI capabilities, or core network element with AI capabilities on the network side (access network or core network).

[0200] It should be noted that network devices can be devices or apparatuses with chips, or devices or apparatuses with integrated circuits, or chips, chip systems, modules, or control units in the devices or apparatuses shown above; this application does not impose any specific limitations. In this application, when referring to network devices, it can refer to the network device itself, or to chips, functional modules, or integrated circuits in the network device that perform the methods provided in this application; this application does not impose any specific limitations.

[0201] (7) Beam: A beam is a communication resource. A beam can be a wide beam, a narrow beam, or other types of beams, and the technology used to form a beam can be beamforming technology or other technical means. Beamforming technology can be specifically digital beamforming technology, analog beamforming technology, and hybrid digital / analog beamforming technology. Different beams can be considered as different resources.

[0202] In New Radio (NR) protocols, a beam can be referred to as a spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, quasi-colocation (QCL) information, QCL assumption, or QCL indication, etc. The beam can be indicated by the transmission configuration indicator state (TCI-state) parameter or by the spatial relation parameter. Therefore, in this application, the beam can be replaced by spatial domain filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (including uplink TCI-state and downlink TCI-state), or spatial relation, etc. The above terms are also equivalent to each other. The beam can also be replaced with other beam-related terms, which are not limited herein.

[0203] The beam used to transmit signals can be referred to as a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting. The transmission beam can also be called a downlink beam. In this application, the transmission beam, downlink beam, channel status information reference signal (CSI-RS), TCI State, downlink / joint transmission configuration number state (DLorjointTCI state), synchronization signal and PBCH block (SSB), and tracking reference signal (TRS) can be interchanged.

[0204] The beam used to receive signals can be referred to as a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. The uplink transmit beam can be indicated by any of the following: spatial relation, uplink TCI-state, or sounding reference signal (SRS) resource (indicating the transmit beam using that SRS). The receive beam can also be referred to as the uplink beam. In this application, the receive beam, uplink beam, uplink transmission configuration number state (UL TCI state), DLorjointTCI state, sounding reference signal (SRS), CSI-RS, SSB, and TRS can be interchanged.

[0205] The transmitting beam can refer to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna, while the receiving beam can refer to the distribution of signal strength in different directions in space of a wireless signal received from an antenna.

[0206] Furthermore, the beam can be a wide beam, a narrow beam, or other types of beam. The beamforming technology can be beamforming technology or other technologies. Specifically, beamforming technology can be digital beamforming technology, analog beamforming technology, hybrid digital beamforming technology, or hybrid analog beamforming technology, etc.

[0207] Beams are generally associated with resources. For example, during beam measurement, network devices measure different beams using different resources. The terminal devices provide feedback on the measured resource quality, allowing the network devices to determine the quality of the corresponding beam. During data transmission, beam information is also indicated through its corresponding resources. For instance, network devices use the TCI field in downlink control information (DCI) to indicate the physical downlink shared channel (PDSCH) beam information of the terminal devices.

[0208] In one possible implementation, multiple beams with the same or similar communication characteristics are considered as a single beam. A beam may include one or more antenna ports for transmitting data channels, control channels, and probe signals, etc. The one or more antenna ports forming a beam can also be considered as a set of antenna ports.

[0209] In the embodiments of this application, unless otherwise specified, a beam refers to the transmit beam of a network device. In beam measurement, each beam of a network device corresponds to a resource, and therefore the beam corresponding to that resource can be uniquely identified by the resource index.

[0210] (8) Transmission Configuration Indicator (TCI): Also known as TCI state. In both uplink and downlink transmissions, correct beamforming is required between network devices and terminal devices for proper transmission. In downlink transmission, the network device needs to indicate to the terminal device which downlink transmit beam it is using. The terminal device can then determine a suitable receive beam based on this downlink transmit beam, which is used to receive information from the network device. In uplink transmission, the network device also needs to indicate to the terminal device which uplink transmit beam it is using to send information. The network device can determine the uplink transmit beam with better signal quality for the terminal device. Both uplink and downlink transmit beams can be indicated by their respective TCI states. Specifically, downlink transmit beams can be indicated by downlink TCI states, and uplink transmit beams can be indicated by uplink TCI states.

[0211] In the 3GPP protocol, network devices can indicate the TCI status to terminal devices through the TCI field in the downlink control information (DCI). The TCI field is 3 bits in size and can be represented by 8 different codepoints. Each codepoint value of the TCI field can be associated with an index of a TCI status. This index uniquely identifies a TCI status, which can be either a downlink TCI status or an uplink TCI status. Each codepoint value of the TCI field can also be associated with two TCI status indices, which uniquely identify two TCI statuses, including one downlink TCI status and one uplink TCI status.

[0212] The downlink TCI status includes several parameters that terminal devices can use to determine information related to the downlink transmit beam, thereby determining the appropriate receive beam to receive information from the network device. The TCI status is configured by the network device for each terminal device, and the structure of the downlink TCI status is shown below:

[0213]

[0214] Each TCI state includes its own index (tci-StateId) and two quasi-colocation information (QCL-info) entries. Each QCL-info entry includes a reference signal resource, indicating that the downlink transmission for that TCI state should use the same downlink timing, frequency offset, or receive beam as that reference signal resource. This is determined by the type of the QCL-info entry. The QCL type can have four values: {typeA, typeB, typeC, typeD}. When the QCL type is typeA, typeB, or typeC, the downlink transmission should use the same downlink timing and frequency offset as that reference signal resource. When the QCL type is typeD, the downlink transmission should use the same receive beam as that reference signal resource. Of the two QCL-info entries mentioned above, one is typeD, and the other is typeA, typeB, or typeC. The terminal device can determine which receive beam to use to receive the corresponding downlink transmission by using the typeD QCL-info entry. The specific execution steps are as follows:

[0215] Network devices indicate a specific downlink TCI state to terminal devices via DCI. The terminal device identifies a reference signal resource in the QCL information for this downlink TCI state (type D). The terminal device then uses the receive beam of this reference signal resource as the receive beam for downlink transmission. It should be noted that the receive beam of this reference signal resource is obtained by the terminal device in advance through a beam management process. Through this beam management process, the terminal device can determine which receive beam is optimal for receiving the reference signal resource and select that beam as the receive beam for that reference signal resource.

[0216] The uplink TCI state includes a reference signal resource, which indicates that uplink transmissions using this TCI state should employ the same uplink transmit beam as the reference signal resource. The terminal device can determine which transmit beam to use for uplink transmission by using this reference signal resource. In the uplink TCI state, the reference signal resource is not included in the QCL-info and does not distinguish between QCL types, because it does not need to reference uplink timing and frequency offset information; only the uplink transmit beam needs to be referenced. The structure of the uplink TCI state is as follows:

[0217]

[0218]

[0219] The specific execution steps are as follows:

[0220] Network devices indicate a specific uplink TCI state to terminal devices via DCI. The terminal device then determines the reference signal resource within that uplink TCI state. The terminal device uses the transmission beam of this reference signal resource as its uplink transmission beam. It should be noted that the transmission beam of this reference signal resource is obtained by the terminal device in advance through a beam management process.

[0221] The following describes the configuration, activation, and indication of TCI status.

[0222] TCI-state configuration: Network devices configure multiple TCI-states to terminal devices via RRC signaling. Each of these TCI-states includes a QCL-Info of type type D. Network devices can also configure TCI-states that do not include a QCL-Info of type type D; however, these TCI-states are not used for data transmission beam indication and will not be discussed further here.

[0223] TCI-state activation: After configuring multiple TCI-states on a network device, eight of them need to be activated via the Medium Access Control (MAC) CE. These eight TCI-states correspond one-to-one with the eight values ​​of the TCI field in the DCI. That is, which eight TCI-states correspond to the eight values ​​of the DCI's TCI field is determined by the MAC CE. The MAC CE structure used to activate TCI is as follows: Figure 1As shown. Fields T0 to T(N-2)x8+7 correspond to the TCI-states configured in the first step, with indices from 0 to (N-2)x8+7 respectively. Each field is 1 bit in size and can have a value of 0 or 1. A value of 1 indicates activation of the TCI-state, and a value of 0 indicates deactivation. Theoretically, each MAC CE can have 8 active fields with values ​​of 1, and the rest are all 0. The TCI-states corresponding to these 8 fields with values ​​of 1 are the 8 TCI-states corresponding to the 8 values ​​of the TCI field in the DCI. For example, the minimum value of the TCI field, 000, corresponds to the TCI-state with the smallest active index in the MAC CE, and so on, one-to-one. There are many types of MAC-CEs; besides MAC-CEs used for TCI-state activation, there are many other types for various purposes. This application only relates to MAC-CEs used for TCI-state / TCI-state combination activation. Therefore, unless otherwise specified, the MAC-CEs mentioned in this application refer to this type of MAC-CE.

[0224] TCI Status Indication: Network devices indicate a specific TCI-state through the TCI field in the DCI. For example, if the TCI field value in the DCI sent by the network device to the terminal device is 000, it indicates that the data transmission beam uses the TCI state corresponding to 000. The reference signal contained in the type D QCL-Info within this TCI state is the channel state information-reference signal (CSI-RS) with index #1, indicating that the beam used for data transmission is the same as the receiving beam corresponding to CSI-RS with index #1. The receiving beam corresponding to CSI-RS with index #1 can be determined through beam measurement procedures and is known to the terminal device. Therefore, by using the specific value of the TCI field, the terminal device can determine the beam corresponding to the data transmission beam and thus use the appropriate beam to send or receive data.

[0225] It should be noted that the three descriptions of TCI state, TCI-state, and TCI state in this article can be used interchangeably.

[0226] In this application, the reference signal of type QCLtypeD in the TCI state is the reference signal resource corresponding to the reference signal resource in the QCL information of typeD in the TCI state.

[0227] (9) Spatial relation: The uplink transmission beam is indicated by the spatial relation, which functions similarly to TCI-state and is used to inform the terminal device which transmission beam to use for uplink transmission.

[0228] Spatial relations also need to be configured via RRC signaling. The configuration structure of a spatial relation is shown below.

[0229]

[0230]

[0231] As shown above, a spatial relation includes the spatial relation ID, cell ID, target reference signal resource, path loss measurement reference signal, and power control parameters. The target reference signal resource (which can be one of SRS / SSB / CSI-RS) is used to indicate the corresponding uplink beam. If the uplink transmission uses spatial relation #1, and this spatial relation #1 includes a target reference signal resource #2, it indicates that the transmit beam of this uplink transmission is the transmit / receive beam of the target reference signal. For example, when the target reference signal resource is an uplink resource SRS, it means that the transmit beam used for the uplink transmission is the transmit beam of that SRS (the transmit beam of that SRS is known). Similarly, if the target reference signal resource is a downlink resource such as SSB / CSI-RS, it means that the transmit beam used for the uplink transmission is the receive beam of that SSB / CSI-RS (the receive beam of that SSB / CSI-RS is known).

[0232] Network devices can configure multiple spatial relations for terminal devices. Then, one of these is activated via MAC-CE for the corresponding data transmission. Uplink transmission resources include, but are not limited to, the Physical Uplink Control Channel (PUCCH), the SRS, and the Physical Uplink Shared Channel (PUSCH), all of which require corresponding spatial relations. The spatial relation of the PUCCH is indicated by MAC-CE signaling. The spatial relation of the SRS is also indicated by MAC-CE signaling. During PUSCH transmission, a specific SRS is associated with it, and the spatial relation of that SRS is used for transmission.

[0233] (10) Unified TCI: Unified TCI is a unified beam indication framework that allows network devices to indicate a beam for terminal devices, which can be used simultaneously for multiple channels and / or reference signals. The common beam can be an uplink common beam, a downlink common beam, or an uplink-downlink common beam, which the terminal device can use in subsequent transmissions. That is, the network device can indicate an uplink common beam for the transmission of multiple uplink channels and / or uplink reference signals. It can also indicate a downlink common beam for the transmission of multiple downlink channels and / or downlink reference signals. Alternatively, it can indicate an uplink-downlink common beam for the transmission of multiple uplink channels and / or uplink reference signals, as well as multiple downlink channels and / or downlink reference signals. In other words, the uplink-downlink common beam can be used for both uplink and downlink transmissions.

[0234] Network devices can configure two TCI states for terminal devices: Downlink / Common Transmission Configuration Number state (DLorjointTCI state) and Uplink Transmission Configuration Number state (UL TCI state).

[0235] Specifically, network devices can simultaneously configure joint / DL TCI states (up to 128) and UL TCI states (up to 64) for terminal devices.

[0236] In the serving cell configuration of RRC signaling, the base station can configure the TCI mode currently used by the UE as joint mode or separate mode. In joint mode, it indicates that a joint TCI state can be used for uplink and downlink transmission simultaneously; in separate mode, the base station needs to indicate that the DL TCI state and UL TCI state are used for uplink and downlink transmission respectively.

[0237] When the UE receives the TCI state activation signaling indicated by MAC-CE, the activation signaling includes the TCI state ID. The UE determines which TCI is activated by MAC-CE according to the RRC configuration.

[0238] Figure 2For the TCI state activation signaling in this application, if the RRC configures the UE to joint mode, the TCI state ID is the ID of the joint TCI state; if the RRC configures the UE to separate mode, the UE determines whether the TCI state ID is the ID of the DL TCI state or the ID of the UL TCI state based on the value of the D / L field. (Specifically, 0 is taken as UL TCI, and 1 is taken as DL TCI).

[0239] (11) Resources: In communication protocols, reference signals are configured in the form of resources. Network devices will configure each reference signal to the terminal device in the form of resources. A resource is a configuration information unit, which usually includes parameters related to a reference signal, such as the time-frequency resource location of the reference signal, the number of ports, the time domain type (periodic / semi-static / aperiodic), etc.

[0240] Resources can be either uplink or downlink signal resources. Uplink signals include, but are not limited to, sounding reference signals (SRS) and demodulation reference signals (DMRS). Downlink signals include, but are not limited to, channel state information reference signals (CSI-RS), cell specific reference signals (CS-RS), user equipment specific reference signals (US-RS), demodulation reference signals (DMRS), and synchronization system / physical broadcast channel blocks (SS / PBCH blocks). The SS / PBCH block can be abbreviated as synchronization signal block (SSB).

[0241] (12) Reference signal: The reference signal can be the reference signal of the serving cell. For example, the serving cell can be the primary cell (Pcell), the secondary cell (Scell), or the primary secondary cell (PScell). Among them, the cell with the primary component carrier (PCC) can be called Pcell, and the cell with the secondary component carrier (SCC) can be called Scell.

[0242] The reference signal can be the reference signal of the neighboring cell of the serving cell (such as the reference signal of the cell corresponding to the additional PCI).

[0243] The reference signal can also be a reference signal associated with the handover candidate cell configuration. The handover candidate cell can also be called a candidate cell or a neighboring cell. The handover candidate cell can be the current serving cell or a non-serving cell. The PCI of the handover candidate cell is different from that of the current primary cell (PCell).

[0244] The terminal device can be configured with one or more candidate cells. The configuration of each candidate cell can include the configuration of reference signal resources, which can be SSB or CSI-RS.

[0245] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and the various methods / designs / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various methods / designs / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various methods / designs / implementations within each embodiment can be combined to form new embodiments, methods, or implementations based on their inherent logical relationships. The following descriptions of the embodiments of this application do not constitute a limitation on the scope of protection of this application.

[0246] Next, we will introduce the possible, non-limiting scenarios involved in this application.

[0247] In high-frequency communication scenarios, a major problem is the sharp decrease in signal energy with transmission distance, resulting in short transmission ranges. To overcome this issue, high-frequency communication employs analog beamforming technology. By weighting the antenna array, the signal energy is concentrated within a small angular range, forming a beam-like signal (called an analog beam, or simply a beam), thereby increasing the transmission distance. Both network devices and terminal devices utilize beamforming for transmission. Specific beams are required for both uplink and downlink data transmission.

[0248] Currently, terminal devices and network devices select appropriate beams through a beam management process and communicate using those beams. The beam management process includes: first, coarse beam alignment based on the SSB (Solar Signal Block), and then fine beam adjustment based on the CSI-RS (Cyber-Independent Signaling System). The beam management process can be divided into three stages, which are described below.

[0249] Phase 1: Coarse beam alignment between network devices and terminal devices.

[0250] The base station performs beam scanning. Specifically, for example... Figure 3 As shown, the base station transmits SSBs to the terminal device at different times using beams from different directions. Simultaneously, the terminal device scans and receives beams, meaning it also receives SSBs from network devices at different times using beams from different directions. The terminal device determines the optimal beam for base station signal transmission and the optimal beam for terminal device signal reception based on the received signal strength. The beam used for base station signal transmission is simply called the base station beam, and the beam used for terminal device signal reception is simply called the terminal beam.

[0251] Specifically, the base station beam includes Terminal beams include like Figure 4 As shown, the base station sends SSB resource configuration information and reports resource configuration information to the terminal device. The base station beam includes beams B0 to B5, i.e., M=5. The terminal beam includes beams U0 to U3, i.e., N=4. The base station uses beam B0 to send SSBs to the terminal device through the corresponding SSB resources, uses beam B1 to send SSBs to the terminal device, and so on, using beam B5 to send SSBs to the terminal device. The terminal device measures the SSBs sent by the base station through beams B0 to B5 respectively through beams U0 to U3, and obtains the measurement results. The terminal device can determine the base station beam with better or better signal quality based on the measurement results. The terminal device feeds back the base station beam with better or better signal quality to the network device. It should be noted that in Phase 1, both the base station beam and the terminal beam can be understood as wide beams.

[0252] Phase Two: Base Station Beam Fine-Tuning.

[0253] The base station determines multiple first candidate beams based on the base station beam with the best or best signal quality identified in Phase 1. Each first candidate beam is a narrow beam. Specifically, for example... Figure 5 As shown, the plurality of first candidate beams includes beams S0 to S2. For example, in the first stage described above, beam B3 is determined. This beam B3 is a wide beam, and the base station determines beams S0 to S2 based on beam B3. The terminal device determines the preferred terminal beam as beam U1 through the first stage described above. Figure 6 As shown, the base station sends CSI-RS configuration information to the terminal device. The network device uses beam S0 to send CSI-RS to the terminal device through the corresponding CSI-RS resources, uses beam S1 to send CSI-RS to the terminal device through the corresponding CSI-RS resources, and uses beam S2 to send CSI-RS to the terminal device through the corresponding CSI-RS resources. The terminal device receives the CSI-RS sent by the base station through different beams via beam U1 and obtains the measurement results. The terminal device can determine the candidate beam with better or best signal quality based on the measurement results. The terminal device then feeds back the first candidate beam with better or best signal quality to the network device. For example, as... Figure 7 As shown, the first candidate beam with better or better signal quality is beam S1. The base station uses this first candidate beam with better or better signal quality as the beam for communication with the terminal equipment.

[0254] Phase 3: UE beam fine-tuning.

[0255] The base station uses beam S1 to send CSI-RS to the terminal device, and the terminal device determines the superior terminal beam as beam U1 through Phase 1. Beam U1 is a wide beam. The terminal device determines multiple second candidate beams based on beam U1, such as... Figure 7 As shown, multiple second candidate beams include beams P1 to P4. The terminal device receives the CSI-RS transmitted by the base station through beam S1 via beams P1 to P4 to obtain the measurement results. The terminal device can select one beam from beams P1 to P4 based on the measurement results and use that beam as the beam for communication with network devices.

[0256] Network devices can be configured to allow terminal devices to report measurement results using one of three methods: periodic reporting, semi-persistent reporting, and aperiodic reporting. Semi-persistent reporting is also known as semi-static reporting.

[0257] Periodic Reporting: The network device sends reference signal resource configuration information to the terminal device. This reference signal resource configuration information includes periodic reference signal resources. The network device configures the terminal device with periodic measurement reference signals. The terminal device can periodically measure the reference signals based on this reference signal resource configuration information and periodically report the measurement results. Optionally, the measurement results obtained from the terminal device's periodic measurement reference signals can be carried on physical uplink control channel (PUCCH) resources.

[0258] Semi-persistent reporting: The terminal device periodically measures the reference signal, but reports the measurement results using a semi-persistent reporting method. In one possible implementation, the network device sends reference signal resource configuration information to the terminal device. This information includes periodic reference signal resources. The network device configures the terminal device's periodic measurement reference signal. When the terminal device receives an activation signaling message (e.g., MAC CE, or DCI) from the network device, it can continuously report the measurement results. Alternatively, the network device can send a deactivation command to the terminal device to deactivate its semi-persistent reporting process. In another possible implementation, both the measurement of the reference signal and the reporting of the measurement results are semi-persistent. When the terminal device receives an activation signaling message from the network device, it continuously measures the reference signal and reports the measurement results. When the terminal device receives a deactivation command from the network device, it stops reporting the measurement results. Furthermore, the measurement results can be carried on PUCCH resources or Physical Uplink Shared Channel (PUSCH) resources.

[0259] Aperiodic reporting: When the terminal device receives a trigger command from the network device, it measures a reference signal and reports the measurement result. After completing the reporting, the terminal device stops reporting the measurement result. Optionally, the reference signal can be a periodic reference signal, a semi-persistent reference signal, or an aperiodic reference signal. Optionally, the measurement result is carried on the PUSCH resource.

[0260] Therefore, measurement results are either reported periodically or triggered by network devices sending instruction signals to the terminal devices for semi-continuous or non-periodic reporting. In the above scenario, the reporting timing is entirely determined by the network devices. In Release 19, an event-triggered measurement result reporting mechanism (hereinafter referred to as event-triggered reporting) was introduced to avoid unnecessary measurement result reporting and unnecessary resource waste.

[0261] Event-triggered measurement result reporting refers to a terminal device reporting the corresponding measurement result to the network device when an event occurs. However, if the service beam between the network device and the terminal device changes after the event occurs, and the terminal device continues to report the corresponding measurement result, the validity of this measurement result is low, leading to a waste of reporting resources.

[0262] In view of this, this application provides a communication method and a communication device to reduce the waste of reporting resources. The communication method and related device provided in this application can be applied to various communication systems. For example, 5th generation mobile communication (5G) systems, new radio (NR) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, universal mobile telecommunication system (UMTS), or future communication systems, vehicle to everything (V2X) communication systems, device to device (D2D) communication systems, Internet of Things (IoT) communication systems, industrial Internet (IIoT) communication systems, or satellite communication systems, etc. The wireless communication systems involved in this application also include, but are not limited to, narrow band-internet of things (NB-IoT) systems. The above-mentioned communication systems include at least one network device and at least one terminal device.

[0263] Figure 8 This is a schematic diagram of one possible, non-limiting system used in the communication method and communication device described in this application. Figure 8 As shown, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 10 may also include an Internet 300. The RAN 100 includes at least one RAN device (which can also be understood as the network device described above, such as...). Figure 8 110a and 110b (collectively referred to as 110) and at least one terminal (which can also be understood as the terminal device introduced above, such as...) Figure 8 RAN100 includes RAN devices 120a-120j, collectively referred to as RAN120. RAN100 may also include other RAN devices, such as wireless relay devices and / or wireless backhaul devices. Figure 8(Not shown in the image). Terminal 120 is connected to RAN device 110 wirelessly. RAN device 110 is connected to core network 200 wirelessly or via wired connection. The core network device in core network 200 and RAN device 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions. Terminals and RAN devices can be interconnected via wired or wireless connections.

[0264] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as 4G, 5G mobile communication systems, or future-oriented evolution systems (such as 6G mobile communication systems). RAN 100 can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), an evolved universal terrestrial radio access (E-UTRA) system, or a wireless fidelity (WiFi) system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0265] RAN device 110, sometimes also referred to as access network device, RAN node, RAN entity, or access node, constitutes part of the communication system and is used to help terminals achieve wireless access. Multiple RAN devices 110 in communication system 10 can be nodes of the same type or different types. In some scenarios, the roles of RAN device 110 and terminal 120 are relative, for example... Figure 8 Network element 120i can be a helicopter or a drone, and it can be configured as a mobile base station. For terminals 120j that access RAN 100 through network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN equipment 110 and terminal 120 are sometimes referred to as communication devices, for example... Figure 8 Network elements 110a and 110b can be understood as communication devices with base station functions, while network elements 120a-120j can be understood as communication devices with terminal functions.

[0266] Figure 9 This is a schematic diagram of another possible, non-limiting system used in the communication method and communication device described in this application. Figure 9As shown, the communication method and communication device in this application can be applied to an O-RAN system, which includes a core network, access network equipment, and a UE. Optionally, the O-RAN system may also include... Figure 9 Other components besides those shown are not specifically limited in this application.

[0267] Access network devices can communicate with the core network (CN) via a backhaul link. Access network devices can also communicate with the UE via an air interface. Specifically, the BBU in the access network device communicates with the core network via a backhaul link. The RU in the access network device communicates with at least one UE via an air interface. The BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located.

[0268] A BBU includes at least one CU and at least one DU, and the CU and DU can communicate with each other via at least one midhaul link.

[0269] Please see Figure 10 , Figure 10 This is a diagram showing the network element functional division and protocol layer structure of an O-RAN device. (Example:) Figure 10 As shown, the CU is a logical node that carries the radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of access network equipment. The CU can connect to network nodes such as the core network through interfaces, such as the E2 interface. Optionally, the CU may have some core network functions. The CU (e.g., the PDCP layer and / or higher) connects to the DU (e.g., the radio link control (RLC) layer and lower layers of the DU) through interfaces, such as the F1 interface. Optionally, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the signaling procedures of F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0270] Optional, such as Figure 10As shown, the CU can be divided into CU-CP and CU-UP. CU-CP is a logical node carrying the control plane (control plane part of PDCP, PDCP-C) layer of the RRC layer and Packet Data Convergence Protocol layer, used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be access and mobility function (AMF) network elements, such as the access and mobility management function (AMF) in a 5G system. AMF network elements are responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the user plane (user plane part of PDCP, PDCP-U) layer of the SDAP layer and Packet Data Convergence Protocol layer, used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements in the core network, such as the user plane function (UPF) in a 5G system, are responsible for data forwarding and receiving in terminal devices. The above CU and DU configurations are merely examples. In practical applications, the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or to have only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements. For example, based on latency, functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0271] One possible implementation is, such as Figure 10 As shown, a DU is a logical node that carries the RLC layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0272] One possible implementation is, such as Figure 10 As shown, the RU is a logical node that carries both lower physical layer (PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP transmission reception point (TRP), a remote radiohead (RRH), or other similar entities. In some examples, the Low-PHY includes PHY processing functions such as fast fourier transform (FFT), inverse fast fourier transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link.

[0273] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through the Lower-Layer Split CUS-Plane (LLS-CUS) interface. LLS-CUS may include a Lower-Layer Split control (LLS-C) interface and a Lower-Layer Splituser (LLS-U) interface, providing the control plane (C-Plane) and user plane (U-Plane) respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and RU. The DU and RU exchange management information via a Lower-Layer Split management (LLS-M) interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0274] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0275] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples.

[0276] In this application, the event-triggered measurement result can be described as a measurement result report, an event-triggered report, an event-triggered or UE-initiated measurement result report, an event-triggered or UE-initiated CSI report, a CSI report, an event-triggered or UE-initiated beam measurement result report, a beam measurement result report, an event-triggered or UE-initiated interference measurement report, a measurement report, an event-related measurement result, or an interference measurement report. This application does not limit the description of the event-triggered measurement result.

[0277] In this application, an event refers to an event related to a UE-initiated report, an event related to a measurement result report initiated by the terminal device, an event related to a report (or measurement result) after the terminal device actively performs a measurement, or an event related to specific conditions for a measurement result report initiated by the terminal device. For example, the terminal device may actively perform measurements (such as beam measurement or channel measurement) to obtain measurement results related to the event. When the measurement results meet the event conditions, the terminal device may report the event-related measurement results. As another example, the terminal device may perform measurements based on reference signals according to the configuration of reference signal resources to obtain measurement results related to the event. When the measurement results meet the event conditions, the terminal device may report the event-related measurement results. Yet another example is that the terminal device actively performs measurements and reports the event-related measurement results when specific conditions are met. The event may also be referred to as any of the following: trigger event, specific event, layer 1 (L1) trigger event, channel state information (CSI) measurement reporting trigger event, beam measurement reporting trigger event, L1 CSI reporting trigger event, or L1 beam measurement reporting trigger event, etc. This application does not limit the naming of the event.

[0278] For example, the events mentioned above include, but are not limited to, one or more of the following:

[0279] Event 1: There exists at least one new beam whose signal quality is greater than that of the serving beam, and the difference between the signal quality of the at least one new beam and the signal quality of the serving beam is greater than or equal to a first threshold value.

[0280] Optionally, event 1 above can be described as follows: there exists at least one new beam whose signal quality is greater than or equal to the signal quality of the serving beam, and the difference between the signal quality of the at least one new beam and the signal quality of the serving beam is greater than a first threshold value.

[0281] Event 2: There exists at least one new beam whose signal quality is greater than the second threshold.

[0282] Optionally, event 2 above can be described as: there exists at least one new beam whose signal quality is greater than or equal to the second threshold value.

[0283] Event 3: The signal quality of the serving beam is less than the third threshold, and there is at least one new beam whose signal quality is greater than the fourth threshold, and the fourth threshold is greater than or equal to the third threshold.

[0284] Optionally, event 3 above can be described as follows: the signal quality of the serving beam is less than the third threshold, and there exists at least one new beam whose signal quality is greater than or equal to the fourth threshold, and the fourth threshold is greater than or equal to the third threshold. Alternatively, the signal quality of the serving beam is less than or equal to the third threshold, and there exists at least one new beam whose signal quality is greater than the fourth threshold, and the fourth threshold is greater than or equal to the third threshold. Alternatively, the signal quality of the serving beam is less than or equal to the third threshold, and there exists at least one new beam whose signal quality is greater than or equal to the fourth threshold, and the fourth threshold is greater than the third threshold. Alternatively, the signal quality of the serving beam is less than or equal to the third threshold, and there exists at least one new beam whose signal quality is greater than or equal to the fourth threshold, and the fourth threshold is greater than or equal to the third threshold.

[0285] Event 4: There exists at least one new beam whose signal quality is less than the fifth threshold value in absolute terms of the difference between the signal quality of the new beam and the signal quality of the serving beam.

[0286] Optionally, event 4 above can be described as: there exists at least one new beam whose signal quality is less than or equal to the fifth threshold value, and the absolute value of the difference between the signal quality of the new beam and the signal quality of the serving beam.

[0287] Event 5: The serving beam is not among the K best new beams measured by the terminal device, where K is an integer greater than or equal to 1.

[0300] It should be noted that the units corresponding to the first to eleventh thresholds can be dBm (decibels per milliwatt) or dB (decibels). The first to eleventh thresholds can be configured or indicated by the network device, or specified by the communication protocol; this application does not impose any specific limitations.

[0301] In this application, "high" can specifically mean "greater than" and "low" can specifically mean "less than". Furthermore, "less than" in the examples can be replaced with "less than or equal to", and "greater than" can be replaced with "greater than or equal to", without any specific limitation in this application.

[0313] 201. The terminal device sends the first uplink signaling to the network device.

[0314] The terminal device sends a first uplink signaling message to the network device, and the network device receives the first uplink signaling message from the terminal device. Optionally, the network device configures the terminal device to report measurement results using an event-triggered method. When an event is triggered or at least one event occurs, the terminal device sends the first uplink signaling message to the network device. For example, event triggering can also be referred to as event occurrence, UE triggering, UE initiated, or event condition fulfillment. Event-triggered reporting can also be called UE-triggered reporting or UE-initiated reporting.

[0315] Optionally, the first uplink signaling can be uplink control information (UCI) signaling, MAC CE signaling, or RRC signaling. The first uplink signaling can be carried on a second uplink resource; in other words, the first uplink signaling can be sent through a second uplink resource. The second uplink resource can be a PUCCH resource, a PUSCH resource, a scheduling request resource, or a reporting indication resource. The second uplink resource is used to carry indication information of an event occurrence (e.g., the first uplink signaling in this application), which is used to indicate to the network device that it needs to report event-triggered measurement results and / or that an event has occurred, or to request resources for carrying event-triggered measurement results.

[0316] Optionally, the second uplink resource can be described as a reporting indication resource, PUCCH indication resource, PUSCH indication resource, scheduling request resource, pre-indication resource, pre-notification resource, event-triggered reporting scheduling request resource, UE-triggered reporting scheduling request resource, first channel resource reported by UE or event-triggered, first uplink resource reported by UE or event-triggered, reporting request resource for UE-triggered beam reporting, reporting indication resource for UE-triggered beam reporting, first PUCCH resource for UE-triggered reporting, or UE-triggered reporting scheduling request resource. Optionally, the second uplink resource can be associated with a PUCCH resource, or with a scheduling request ID, or with a scheduling request resource, or a specially configured PUCCH resource; this invention does not limit this.

[0317] This application provides multiple implementations of the first uplink signaling, such as implementation method A and implementation method B described below.

[0318] Implementation Method A: The first uplink signaling can be used to request the network device to schedule first uplink resources for the terminal device, and / or to indicate that an event has occurred, wherein the first uplink resources are used to carry the terminal device's event-triggered measurement results. Optionally, before the terminal device sends the first uplink signaling to the network device (i.e., before step 201), the network device pre-configures the first uplink resources for the terminal device; or, the network device does not configure the first uplink resources for the terminal device.

[0319] Optionally, the above implementation method A is applicable to Figure 12 The indicated event trigger reporting method. Figure 12 The event-triggered reporting method shown can be called the Mode A reporting method. For example... Figure 12 As shown, the reporting method of Mode A includes the following steps 301 to 303.

[0320] 301. The terminal device sends a first uplink signaling message to the network device, the first uplink signaling message being used to request the network device to schedule a first uplink resource for the terminal device, and / or to indicate that an event has occurred. Optionally, at least one event has occurred for the terminal device.

[0321] 302. The network device sends a first scheduling signaling message to the terminal device. The first scheduling signaling message is used to indicate or schedule the first uplink resource.

[0322] Optionally, the first scheduling signaling is uplink scheduling signaling, used to schedule PUSCH for the terminal device. That is, the first uplink resource is the PUSCH resource.

[0323] Optionally, the first scheduling signaling is downlink scheduling signaling, used to schedule PUCCH for the terminal equipment. That is, the first uplink resource is PUCCH resource.

[0324] Optionally, the first scheduling signaling is DCI.

[0325] 303. The terminal device sends an event-triggered measurement result to the network device via the first uplink resource.

[0326] Optionally, in implementation method A, the first uplink resource can be any one of the following: PUCCH resource, PUSCH resource, event-triggered reporting resource, UE-triggered reporting resource, event-triggered channel resource, event-triggered uplink resource, dynamically scheduled PUSCH resource, second channel resource, aperiodic PUSCH resource, semi-persistent PUCCH resource or semi-persistent PUSCH resource, UE-triggered beam reporting reporting resource, or event-triggered beam reporting reporting resource. That is, the measurement result based on event triggering is carried in any of the above first uplink resources, and this application does not limit it.

[0327] Implementation method B: The first uplink signaling is used to notify the network device that the measurement result triggered by the event will be carried in the first uplink resource, and / or to indicate that an event has occurred. Optionally, before the terminal device sends the first uplink signaling to the network device (i.e., before step 201), the network device has pre-configured the first uplink resource for the terminal device. For example, the network device pre-configures and activates the first uplink resource for the terminal device, or the network device pre-configures the first uplink resource for the terminal device that is either inactive or already activated.

[0328] Optionally, implementation method B described above is applicable to Figure 13 The indicated event trigger reporting method. Figure 13 The event-triggered reporting method shown can be called the Mode B reporting method. For example... Figure 13 As shown, the reporting method of Mode B includes the following steps 401 to 402.

[0329] The 401 terminal device sends a first uplink signaling to the network device. The first uplink signaling is used to notify the network device that the event-triggered measurement result will be carried on a first uplink resource, and / or to indicate that an event has occurred. Optionally, at least one event has occurred at the terminal device.

[0330] 402. The terminal device sends an event-triggered measurement result to the network device via the first uplink resource.

[0331] Before sending event-triggered measurement results to the network device, the terminal device can notify the network device via a first uplink signaling. The terminal device will then send the event-triggered measurement results to the network device on a pre-configured first uplink resource. This event-triggered reporting method can be called the Mode B reporting method.

[0332] Optionally, in this scenario, the first uplink resource can be replaced by any of the following: PUCCH resource, PUSCH resource, pre-configured PUSCH resource, pre-configured PUCCH resource, event-triggered reporting resource, UE-triggered reporting resource, UE or event-triggered channel resource, UE or event-triggered uplink resource, periodic PUSCH resource, periodic PUCCH resource, second channel resource, UE-triggered beam reporting resource, or event-triggered beam reporting resource. That is, the event-triggered measurement result is carried in any of the above first uplink resources, and this application does not limit this. For example, the first uplink resource can be a configured grant PUSCH (CG-PUSCH) or periodic PUCCH resource pre-configured by the network device for the terminal device.

[0333] Optionally, the first uplink signaling can be replaced with other descriptions, such as the first uplink signaling being used to request the network device to schedule the second uplink signaling, and the second uplink signaling being used to carry the event-triggered measurement results; or, the first uplink signaling being used to instruct the network device that the terminal device needs to report the event-triggered measurement results; or, the first uplink signaling being used to indicate that an event has occurred, which refers to a specific event that triggered the reporting of measurement results; or, the first uplink signaling being used to request the network device to schedule uplink resources to carry the event-triggered measurement results.

[0334] Optionally, event-triggered measurements may include at least one of the following:

[0335] 1. Service beam index. Optionally, the service beam index can be any of the following:

[0336] The index of the QCL type D reference signal in the TCI state indicated by the network device to the terminal device;

[0337] The network device is the SSB index corresponding to the SSB resource associated with the QCL type D reference signal in the TCI state indicated by the terminal device;

[0338] The index of the QCL type D reference signal in the downlink / common TCI state and uplink TCI state of the current uplink and downlink transmission applications of the terminal device;

[0339] The SSB index of the SSB resource associated with the QCL type D reference signal in the downlink / common TCI state and uplink TCI state of the current uplink and downlink transmission application of the terminal device;

[0340] The index of the reference signal with the best signal quality among the quasi-QCL type D reference signals in one or more TCI states activated by the network device for the terminal device;

[0341] The network device is the index of the reference signal with the worst signal quality among the QCL type D reference signals in one or more TCI states activated by the terminal device;

[0342] The network device configures or indicates an index of one or more reference signals for monitoring the service beam for the terminal device.

[0343] 2. Quality of the serving beam. For example, the RSRP, SINR, L1-RSRP, L1-SINR, SS-RSRP, CSI-RSRP, SS-SINR, and CSI-SINR of the serving beam.

[0344] The serving beam may include one or more beams, and this application does not limit this. The number of serving beams can be determined based on the number of UL / DL / joint TCI states indicated by the network device, such as the UL / DL / joint TCI states indicated by DCI signaling. Alternatively, the number of beams included in the serving beam may be predefined by the protocol or preconfigured by the network device. Or, the maximum number of beams included in the serving beam may be predefined by the protocol or configured by the network device.

[0345] 3. The index of the new beam can also be understood as the index of the reference signal with QCL type type D in the activated TCI-states (excluding the indicated TCI-state), or it can be the index of one or more reference signals (excluding the reference signal corresponding to the serving beam) in the reference signals configured by the network device (such as the reference signal configured by the network device for measurement, or the reference signal configured by the network device for the terminal device to monitor the occurrence of events).

[0346] 4. Quality of the new beam. For example, the RSRP, SINR, L1-RSRP, L1-SINR, SS-RSRP, CSI-RSRP, SS-SINR, and CSI-SINR of the new beam.

[0347] The new beam may include one or more beams, and this application does not limit this. The number of beams included in the new beam may be predefined by the protocol or preconfigured by the network device. Alternatively, the maximum number of beams included in the new beam may be predefined by the protocol or configured by the network device.

[0348] 5. Cell Information #1 can also be understood as which cell the reported event-triggered measurement result corresponds to, or the reference signal resource of which cell the event-triggered measurement result information refers to. For example, Cell Information #1 can be the handover candidate cell identifier, non-serving cell identifier, component carrier (CC) index, or PCI.

[0349] 6. Cell Information #2 can also be understood as the cell whose event reporting configuration corresponds to the event-triggered measurement results. For example, Cell Information #2 can be the handover candidate cell identifier, non-serving cell identifier, component carrier (CC) index, or PCI.

[0350] 7. Reasons why the service beam quality is below a threshold (e.g., the first preset threshold). For example, network equipment beam misalignment, terminal equipment receiving beam misalignment, transmit / receive beam misalignment, etc. "Misalignment" can also be replaced with terms like "expired" or "invalid." Alternatively, it could indicate whether a CSI-RSset measurement with "repetition" set to "on" is triggered to poll the terminal equipment's receiving beam.

[0351] 8. Reference signal resource set index, such as the CSI-RS resource set index, the CSI-IM interference measurement (IM) resource set index, the CSI-SSB resource set index, or a reference signal resource set index configured by the network device for the terminal device to monitor the occurrence of events, used to indicate which reference signal resource set the reported serving beam and / or second beam belongs to.

[0352] 9. Report configuration index, such as CSI report configuration identifier (CSI-ReportConfigId), or event-triggered reporting configuration index.

[0353] 10. Event information, such as an index of the event that occurred, or one or more bits indicating whether the event occurred. For example, event information may consist of J bits. An index used to indicate an event that has occurred. For example, event information includes X bits, each corresponding to one of X events. The c-th bit of the X bits indicates whether the event corresponding to that c-th bit has occurred, where c = 1, 2, ..., X. For instance, if the c-th bit has a value of "0", then the c-th bit indicates that the event corresponding to that c-th bit has occurred; or, if the c-th bit has a value of "1", then the c-th bit indicates that the event corresponding to that c-th bit has occurred.

[0354] 11. Capability Index: Used to determine the maximum number of SRS ports.

[0355] 12. Channel state information, which may include one or more of the following: precoding matrix indication (PMI), rank indication (RI), channel quality information (CQI), and layer indication (LI).

[0356] 202. The network device sends beam indication signaling to the terminal device, and the terminal device receives beam indication signaling from the network device accordingly.

[0357] The network device sends beam indication signaling to the terminal device, which indicates the serving beam of the terminal device. Optionally, this beam indication signaling can be replaced with other descriptions, such as indicating a switch in the serving beam of the terminal device, indicating a change in the serving beam between the network device and the terminal device, indicating a change in the serving beam of the terminal device, or indicating that a new beam is used as the serving beam. For example, the beam indication signaling can indicate a new serving beam or a new TCI state. The beam indication signaling can also be described as beam switching signaling or TCI state indication signaling. For example, the beam indication signaling can be DCI signaling carrying a transmission configuration indication (TCI) field, which indicates TCI state(s) and / or TCI-UL-State(s), corresponding to one or a pair of TCI states activated by the MAC CE signaling. Alternatively, the beam indication signaling can be RRC signaling, used to configure a downlink / common TCI state list (dl-OrJointTCI-StateList) for the terminal device. Optionally, the downlink / common TCI state list includes one or more TCI states; or, the RRC signaling is used to configure a downlink / common TCI state list (dl-OrJointTCI-StateList) and an uplink TCI state list (ul-TCI-StateList) for the terminal device. Optionally, the downlink / common TCI state list contains only one or more TCI states, and the uplink TCI state list contains only one or more UL TCI states. For example, the beam indication signaling can be MAC CE signaling, which is used to activate one or more TCI states in the downlink / common TCI state list, or the MAC CE is used to activate one or more pairs of TCI states, each pair of TCI states containing one downlink TCI state and one uplink TCI state, the downlink TCI state in each pair of TCI states coming from the downlink / common TCI state list, and the uplink TCI state in each pair of TCI states coming from the uplink TCI state list.

[0358] Optionally, the service beam may include one or more of the following:

[0359] 1. The beam corresponding to the QCL type D reference signal in the TCI status indicated by the network device for the terminal device.

[0360] Optionally, the service beam can also be described as a reference signal. In this implementation, the reference signal may optionally be a QCL type D reference signal in the TCI state indicated by the network device to the terminal device.

[0361] Optionally, the service beam can also be described as a service beam measurement resource. In this implementation, the service beam measurement resource can optionally be the reference signal resource corresponding to the QCL type D reference signal in the TCI state indicated by the network device to the terminal device.

[0362] 2. The beam corresponding to the SSB resource associated with the QCL type D reference signal in the TCI state indicated by the network device for the terminal device.

[0363] The SSB resource associated with the QCL type D reference signal in the TCI state indicated by the network device to the terminal device is an SSB resource that has a QCL relationship with the QCL type D reference signal. For example, this SSB resource is the source QCL resource in the QCL chain, and the source QCL resource is an SSB resource. This QCL chain is determined based on the QCL type D reference signal in the TCI state indicated by the network device to the terminal device. For example, the QCL resource corresponding to the QCL type D reference signal in the TCI state indicated by the network device to the terminal device is a CSI-RS resource. The QCL resource corresponding to the QCL type D reference signal in the TCI state corresponding to this CSI-RS resource is a TRS resource. The TCI state corresponding to this CSI-RS resource can be understood as the TCI state used by the network device when sending the CSI-RS corresponding to this CSI-RS resource. The QCL resource corresponding to the QCL type D reference signal in the TCI state corresponding to this TRS resource is an SSB resource. The TCI state corresponding to this TRS resource can be understood as the TCI state used by the network device when sending the TRS corresponding to this TRS resource. Therefore, it can be seen that the QCL resources corresponding to the QCL type D reference signal in the TCI state indicated by the network device to the terminal device (such as CSI-RS resources), the QCL resources corresponding to the QCL type D reference signal in the TCI state corresponding to the CSI-RS resource (such as TRS resources), and the QCL resources corresponding to the QCL type D reference signal in the TCI state corresponding to the TRS resource (such as SSB resources) constitute a QCL chain. The source QCL resource of this QCL chain is the SSB resource, that is, the SSB resource associated with the QCL type D reference signal in the TCI state indicated by the network device to the terminal device is this SSB resource.

[0364] Optionally, the service beam can also be described as a reference signal. In this implementation, the reference signal may optionally be the SSB associated with the QCL type D reference signal in the TCI state indicated by the network device to the terminal device.

[0365] Optionally, the service beam can also be described as a service beam measurement resource. In this implementation, the service beam measurement resource may optionally be the SSB resource associated with the QCL type D reference signal in the TCI state indicated by the network device for the terminal device.

[0367] Optionally, the service beam can also be described as a reference signal. In this implementation, the reference signal can optionally be a QCL type D reference signal in the downlink / common TCI state of the current uplink and downlink transmission application of the terminal device and a reference signal configured in the uplink TCI state.

[0368] Optionally, the service beam can also be described as a service beam measurement resource. In this implementation, the service beam measurement resource can optionally be the QCL resource corresponding to the QCL type D reference signal in the downlink / common TCI state of the current uplink and downlink transmission application of the terminal device, and the resource corresponding to the reference signal configured in the uplink TCI state.

The beam corresponding to the SSB resource associated with the QCL type D reference signal in the downlink / common TCI state of the current uplink and downlink transmission application of the terminal device, and the beam corresponding to the SSB resource associated with the reference signal configured in the uplink TCI state.

[0370] For information on SSB resources associated with QCL type D reference signals, please refer to the aforementioned explanations; they will not be repeated here.

[0371] Optionally, the reference signal corresponding to the service beam can also be described as a reference signal. In this implementation, optionally, the reference signal is the SSB associated with the QCL type D reference signal in the downlink / common TCI state of the current uplink and downlink transmission application of the terminal device and the SSB associated with the reference signal configured in the uplink TCI state.

[0372] Optionally, the reference signal corresponding to the service beam can also be described as a service beam measurement resource. In this implementation, the service beam measurement resource can optionally be the SSB resource associated with the QCL type D reference signal in the downlink / common TCI state of the current uplink and downlink transmission application of the terminal device, and the SSB resource associated with the reference signal configured in the uplink TCI state.

[0373] 5. The beam corresponding to the reference signal with the best signal quality among the QCL type D reference signals in one or more TCI states activated by the network device for the terminal device.

[0374] Optionally, the reference signal corresponding to the service beam can also be described as a reference signal. In this implementation, optionally, the reference signal is the reference signal with the best signal quality among the quasi-QCL type D reference signals in one or more TCI states activated by the network device for the terminal device.

[0375] Optionally, the reference signal corresponding to the serving beam can also be described as a serving beam measurement resource. In this implementation, the serving beam measurement resource can optionally be: the reference signal resource with the best signal quality among one or more TCI states activated by the network device for the terminal device, specifically the quasi-QCL type D reference signal.

[0376] 6. The beam corresponding to the reference signal with the worst signal quality among the QCL type D reference signals in one or more TCI states activated by the network device for the terminal device.

[0377] Optionally, the reference signal corresponding to the service beam can also be described as a reference signal. In this implementation, optionally, the reference signal is the reference signal with the worst signal quality among the QCL type D reference signals in one or more TCI states activated by the network device for the terminal device.

[0378] Optionally, the reference signal corresponding to the serving beam can also be described as a serving beam measurement resource. In this implementation, the serving beam measurement resource can optionally be: the reference signal resource corresponding to the reference signal with the worst signal quality among the QCL type D reference signals in one or more TCI states activated by the network device for the terminal device.

[0379] 7. The network device configures or indicates to the terminal device one or more reference signals corresponding to the monitoring service beam.

[0380] Optionally, the reference signal corresponding to the service beam can also be described as a reference signal. In this implementation, optionally, the reference signal is one or more reference signals configured or indicated by the network device for the terminal device to monitor the service beam.

[0381] Optionally, the reference signal corresponding to the serving beam can also be described as a serving beam measurement resource. In this implementation, the serving beam measurement resource may optionally be one or more reference signal resources configured or indicated by the network device for the terminal device to monitor the serving beam.

[0382] Optionally, the aforementioned reference signal may be SSB, CSI-RS, SRS, TRS, or a road loss reference signal, and this application does not specify the specific reference signal.

[0383] The new beam includes one or more of the following:

[0384] 1. A beam that is different from the serving beam;

[0385] 2. The beam corresponding to the QCL type D reference signal in the TCI state activated by the network device for the terminal device;

[0387] 4. The network device is configured for the terminal device to monitor the reference signal corresponding to one or more new beams.

[0388] Optionally, the aforementioned reference signal may be SSB, CSI-RS, SRS, TRS, or a road loss reference signal, and this application does not specify the specific reference signal.

[0389] 203. If the first condition is met, the terminal device will not send event-triggered measurement results on the first uplink resource.

[0390] If the first condition is met, the terminal device will not transmit event-triggered measurement results on the first uplink resource. Please refer to the following text for details on the first condition. Figures 14 to 16 The relevant information is provided in the text.

[0391] In this application, if the first condition is met, the terminal device will not send event-triggered measurement results on the first uplink resource. This reduces unnecessary reporting of event-triggered measurement results, improves the efficiency of reporting measurement results, and saves reporting resources.

[0392] In this application, the statement that the terminal device does not send event-triggered measurement results on the first uplink resource can be replaced with other descriptions. For example, the terminal device does not send event-triggered measurement results, or the terminal device discards event-triggered measurement results, or the terminal device clears event-triggered measurement results, or the terminal device ignores the first scheduling signaling from the network device, wherein the first scheduling signaling is used to indicate or schedule the first uplink resource. Alternatively, the terminal device does not send event-triggered measurement results on the first uplink resource indicated or scheduled by the first scheduling signaling, or the terminal device does not send the first uplink resource, or the terminal device does not send the first uplink resource indicated or scheduled by the first scheduling signaling. Optionally, the first uplink resource indicated or scheduled by the first scheduling signaling does not have multiplexed hybrid automatic repeat request-acknowledgement (HARQ-ACK) messages, transport blocks, or traditional CSI measurement results. The traditional CSI measurement results can also be referred to as non-event-triggered reporting, or traditional CSI reporting, or CSI reporting configured by CSI-ReportConfig, or CSI reporting triggered or configured by network devices, or CSI reporting without event information configured by LTM-CSI-ReportConfig, or CSI reporting without event-related information in CSI-ReportConfig, or CSI reporting that does not contain event information. The naming of these terms is not limited in the embodiments of this application.

[0393] Optionally, the event-triggered measurement result may be a measurement result indicated by the first uplink signaling, or a measurement result corresponding to the event condition determined by the terminal device when sending the first uplink signaling, or a measurement result of the event indicated by the first scheduling signaling (e.g., DCI), or all event-triggered measurement results. Further, the event-triggered measurement result may be a measurement result triggered by an event related to the serving beam (e.g., any one or more of the aforementioned events 1, 3, 4, 5, 10, and 11), or an event-triggered measurement result may be an event-triggered measurement result of a cell whose beam indication signaling indicates TCI status among all cells, or an event-triggered measurement result related to the serving beam of a cell whose beam indication signaling indicates TCI status among all cells. Specifically, the measurement result indicated by the first uplink signaling can be understood as follows: if the second uplink resource where the first uplink signaling resides is associated with a measurement report triggered by an event, then the measurement result indicated by the first uplink signaling is the measurement report triggered by that event. The measurement result of the event indicated by the first scheduling signaling (e.g., DCI) can be understood as follows: if the first scheduling signaling indicates measurement report information triggered by the event (e.g., event-triggered report configuration index, trigger status index associated with the event-triggered report configuration, CSI request, etc.), then the measurement result of the event indicated by the first scheduling signaling (e.g., DCI) is the measurement report triggered by that event.

[0394] In step 203 of this application, the first condition can be implemented in various ways, which will be illustrated below with some implementation examples. Other implementation methods are also applicable to this application, and this application does not impose any specific limitations.

[0395] Implementation Example 1: Please refer to Figure 14 , Figure 14 This is a possible implementation example diagram for the first condition.

[0396] like Figure 14As shown, the terminal device sends a first uplink signaling to the network device through a second uplink resource. The first uplink signaling is used to request the network device to schedule the first uplink resource for the terminal device. The first uplink resource is used to carry event-triggered measurement results. One possible interpretation is that the second uplink resource is a periodic uplink resource (e.g., a PUCCH resource or PUSCH resource), which includes one or more transmission cycles (or transmission opportunities). The terminal device sends the first uplink signaling during one or more or all of the transmission cycles (or transmission opportunities) of the second uplink resource. Next, the network device receives the first uplink signaling and sends a first scheduling signaling to the terminal device. Correspondingly, the terminal device receives the first scheduling signaling from the network device. The first scheduling signaling is used to indicate or schedule the first uplink resource. Then, the network device sends a beam indication signaling to the terminal device, and correspondingly, the terminal device receives the beam indication signaling from the network device. Therefore, the first condition in this application includes at least one of the following:

[0397] Condition A1: The terminal device receives the beam indication signaling after the first duration of receiving the first scheduling signaling and before the first uplink resource;

[0398] Condition A2: The terminal device receives beam indication signaling after a first duration following the receipt of the first scheduling signaling, and the first uplink resource is located after a second duration following the receipt of the beam indication signaling by the terminal device;

[0399] Condition A3: After sending the first uplink signaling, the terminal device receives beam indication signaling after the first duration of receiving the first scheduling signaling and before the first uplink resource;

[0400] Condition A4: After the terminal device sends the first uplink signaling, and after a first duration following the receipt of the first scheduling signaling, it receives the beam indication signaling, and the first uplink resource is located after a second duration following the receipt of the beam indication signaling by the terminal device.

[0401] In this way, when the terminal device receives the first scheduling signaling first and then the beam indication signaling, it can realize that it does not need to send the event-triggered measurement results on the first uplink resource indicated by the first scheduling signaling, thereby reducing the overhead of uplink resources.

[0402] In this process, the network device indicates the first uplink resource, and the terminal device obtains information about the time-domain and frequency-domain resources within the first uplink resource. Therefore, the description "before the first uplink resource" can be replaced with "before the time-domain resources within the first uplink resource," "before the symbol where the first uplink resource is located," or "before the first uplink resource scheduled or indicated by the first scheduling signaling."

[0403] The description of "receiving beam indication signaling" can be replaced with "the symbol where the beam indication signaling is received", "when the beam indication signaling is received", or "the moment the beam indication signaling is received".

[0404] The phrase "after the terminal device receives the first scheduling signaling for a first duration" can be understood as "after the terminal device receives the first scheduling signaling and a first duration has elapsed".

[0405] The phrase "after the second duration after the terminal device receives the beam indication signaling" can be understood as "the moment the terminal device receives the beam indication signaling and after the second duration has elapsed".

[0406] Optionally, the first scheduling signaling can be DCI signaling, carried on the PDCCH channel. Optionally, the DCI signaling can include a field indicating that the first scheduled uplink resources are used to carry event-triggered measurement results. Alternatively, the DCI signaling can include a CSI request field, where the CSI request indicated in the DCI is associated with an event-triggered trigger state. Each event-triggered trigger state is associated with one or more event-triggered reported configurations, the description of which is provided later. Alternatively, the DCI signaling can include an event-triggered report configuration index field.

[0407] Optionally, the first duration can be configured by the network device, determined by the capabilities of the terminal device, or related to any one or more of the provisions of the communication protocol. For example, the first duration is related to the time it takes for the terminal device to process the first scheduling signaling. The first duration includes N time units, where N is an integer greater than or equal to 0. For example, this time unit can be an hour, minute, second, millisecond, microsecond, nanosecond, frame, subframe, slot, symbol, sampling time (Ts), or basic time unit (Tc), etc. Regarding the description of the second duration, the second duration is related to the time it takes for the terminal device to process beam indication signaling, and the second duration can include M time units, where M is an integer greater than or equal to 0. The rest is similar to the description of the first duration, and will not be repeated here.

[0408] Optionally, assume that the first duration includes 0 time units, and the second duration also includes 0 time units.

[0409] The description of condition A1 can be replaced as: the terminal device receives the beam indication signaling after receiving the first scheduling signaling and before receiving the first uplink resource;

[0410] The description of condition A2 can be replaced as follows: The terminal device receives the beam indication signaling after receiving the first scheduling signaling, and the first uplink resource is located after the terminal device receives the beam indication signaling;

[0411] Then the description of condition A3 can be replaced as: After the terminal device sends the first uplink signaling, after receiving the first scheduling signaling and before receiving the first uplink resource, it receives the beam indication signaling;

[0412] The description of condition A4 can be replaced as follows: After the terminal device sends the first uplink signaling and after receiving the first scheduling signaling, it receives the beam indication signaling, and the first uplink resource is located after the time when the terminal device receives the beam indication signaling.

[0413] The description "after receiving the first scheduling signaling" can be replaced with "after receiving the time-domain resources of the first scheduling signaling" or "after receiving the symbol of the first scheduling signaling".

[0414] The description "after sending the first uplink signaling" can be replaced with "after the time domain resources for sending the first uplink signaling" or "after receiving the symbol for sending the first uplink signaling".

[0415] Implementation Example 2: Please refer to Figure 15 , Figure 15 This is an example diagram of another possible implementation of the first condition.

[0416] like Figure 15 As shown, the terminal device sends a first uplink signaling to the network device through a second uplink resource. The first uplink signaling is used to request the network device to schedule the first uplink resource for the terminal device and / or indicate the occurrence of an event. The first uplink resource is used to carry measurement results triggered by the event. One possible interpretation is that the second uplink resource is a periodic uplink resource (e.g., a PUCCH resource or a PUSCH resource), which includes one or more transmission cycles (or transmission opportunities). The terminal device sends the first uplink signaling during one or more or all of the transmission cycles (or transmission opportunities) of the second uplink resource. Next, the network device receives the first uplink signaling and sends a beam indication signaling to the terminal device. Correspondingly, the terminal device receives the beam indication signaling from the network device. Then, optionally, the network device sends a first scheduling signaling to the terminal device. Correspondingly, the terminal device receives the first scheduling signaling from the network device. The first scheduling signaling is used to indicate or schedule the first uplink resource. Therefore, the first condition in this application includes at least one of the following:

[0417] Condition B1: The terminal device receives beam indication signaling after the third duration of sending the first uplink signaling and before the fourth duration.

[0418] Condition B2: The terminal device receives beam indication signaling after the third duration of sending the first uplink signaling, but does not receive the first scheduling signaling;

[0419] Condition B3: The terminal device receives beam indication signaling after the third time period and before the fourth time period after sending the first uplink signaling, but does not receive the first scheduling signaling;

[0420] Condition B4: The terminal device receives beam indication signaling three hours after sending the first uplink signaling, and receives the first scheduling signaling five hours after receiving the beam indication signaling;

[0421] Condition B5: The terminal device receives beam indication signaling after the third duration and before the fourth duration after sending the first uplink signaling, and receives the first scheduling signaling after the fifth duration after receiving the beam indication signaling;

[0422] Condition B6: The terminal device receives beam indication signaling three time intervals after sending the first uplink signaling, and receives the first scheduling signaling five time intervals after receiving the beam indication signaling.

[0423] Condition B7: The terminal device receives beam indication signaling after a third duration and before a fourth duration after sending the first uplink signaling, and receives the first scheduling signaling before a fifth duration after receiving the beam indication signaling.

[0424] The phrase "after the third duration of the first uplink signaling sent by the terminal device and before the fourth duration" can be understood as "after the terminal device has sent the first uplink signaling and experienced the third duration, and before the time when the first uplink signaling was sent plus the fourth duration".

[0425] The phrase "after the terminal device receives the beam indication signaling for the fifth time period" can be understood as "the moment the terminal device receives the beam indication signaling and after the fifth time period has elapsed".

[0426] The phrase "before the terminal device receives the beam indication signaling for the fifth duration" can be understood as "the time when the terminal device receives the beam indication signaling plus the time when the fifth duration is located".

[0427] Using the above method, under conditions B1-B3, if the terminal device receives the beam indication signaling first, it knows that it does not need to report the event-triggered measurement results, and the terminal can ignore the first scheduling signaling. Under conditions B4-B7, if the terminal device receives the beam indication signaling first and then the first scheduling signaling, it can perceive that it does not need to send the event-triggered measurement results on the first uplink resource indicated by the first scheduling signaling, thereby reducing the uplink resource overhead.

[0428] Optionally, the third duration can be configured by the network device, determined by the capabilities of the terminal device, or related to any one or more of the provisions in the protocol. For example, the third duration is related to the duration of the network device processing the first uplink signaling, or to the UE's RF capability for switching uplink and downlink. The third duration includes N time units, where N is an integer greater than or equal to 0. For example, this time unit can be an hour, minute, second, millisecond, microsecond, nanosecond, frame, subframe, slot, symbol, sampling time (Ts), or basic time unit (Tc), etc. Regarding the description of the fourth and fifth durations, the fifth duration includes M time units, and optionally, the fifth duration is related to the time of the terminal device processing beam indication signaling, etc.; the fourth duration includes X time units, and optionally, the fourth duration can be the maximum time interval between the first uplink signaling and the first scheduling signaling configured by the network device. Optionally, the aforementioned fourth duration is greater than or equal to the third duration. The rest is similar to the description of the aforementioned third duration and will not be repeated here.

[0429] Optionally, assume that the third duration includes 0 time units, the fourth duration includes 0 time units, and the fifth duration includes 0 time units.

[0430] The description of condition B1 can be replaced with: After sending the first uplink signaling, the terminal device receives the beam indication signaling;

[0431] The descriptions of conditions B2 and B3 can be replaced as follows: After sending the first uplink signaling, the terminal device receives the beam indication signaling, but does not receive the first scheduling signaling.

[0432] The description of conditions B4-B7 can be replaced as follows: After sending the first uplink signaling, the terminal device receives the beam indication signaling, and after receiving the beam indication signaling, it receives the first scheduling signaling.

[0433] Optionally, in Implementation Example 1 and Implementation Example 2 above, when the first condition is met, the terminal device can ignore the first scheduling signaling, thereby avoiding the terminal device from sending event-triggered measurement results on the first uplink resource indicated by the first scheduling signaling. Optionally, the first uplink resource scheduled by the first scheduling signaling does not have multiplexing of HARQ-ACK, transport blocks, traditional CSI reports, etc.

[0434] Optionally, in Implementation Examples 1 and Implementation Examples 2 above, if the terminal device does not receive the first scheduling signaling and beam indication signaling within a third and fourth time period after sending the first uplink signaling, the terminal device retransmits the first uplink signaling to the network device until the terminal device receives the first scheduling signaling or reaches the maximum number of retransmissions of the first uplink signaling (the maximum number of retransmissions can be configured by the network device). This can be understood as follows: if the terminal device does not receive the first scheduling signaling and beam indication signaling within a third and fourth time period after sending the first uplink signaling, the terminal device can continue sending the first uplink signaling. That is, the terminal can continuously send up to N first uplink signalings, which are sent during N consecutive transmission opportunities or periods of the second uplink resource. Optionally, N can be the maximum number of retransmissions of the first uplink signaling configured by the network device, and N is a positive integer greater than or equal to. Optionally, the first scheduling signaling and / or beam indication signaling are not received within the time interval of N consecutive second uplink resource transmission opportunities or periods.

[0435] Optionally, in Implementation Examples 1 and Implementation Examples 2 above, if the terminal device does not receive the first scheduling signaling within a third and fourth time period after sending the first uplink signaling, and the terminal device receives beam indication signaling within a third and fourth time period after sending the first uplink signaling, then the terminal device stops retransmitting the first uplink signaling and re-determines whether the event has occurred by measuring the reference signal corresponding to the event. This facilitates the terminal device in determining whether to report the event-triggered measurement results after the beam indication signaling, reducing reporting overhead. Furthermore, it reduces the retransmission of the first uplink signaling by the terminal device, saving reporting resources.

[0436] Optionally, the implementation examples 1 and 2 shown above are applicable to Figure 12 The corresponding Mode A reporting method. This can be understood as the network device configuring the terminal device with the Mode A reporting method, or in other words, the measurement report corresponding to the event-triggered measurement result is configured with the Mode A reporting method.

[0437] Implementation Example 3: Please refer to Figure 16 , Figure 16 This is an example diagram of another possible implementation of the first condition.

[0438] like Figure 16 As shown, the terminal device sends a first uplink signaling to the network device through a second uplink resource. This first uplink signaling notifies the network device that event-triggered measurement results will be carried on the first uplink resource, which is used to carry these results. Optionally, before the terminal device sends the first uplink signaling to the network device, the network device pre-configures and activates the first uplink resource for the terminal device; or, the network device pre-configures the first uplink resource for the terminal device, or pre-configures an inactive or activated first uplink resource for the terminal device. One possible interpretation is that the second uplink resource is a periodic uplink resource (e.g., a PUCCH resource or a PUSCH resource), comprising one or more transmission cycles (or transmission times). The terminal device sends the first uplink signaling during one or more or all of the transmission cycles (or transmission times) of the second uplink resource. The first uplink resource is associated with the second uplink resource; for example, the first uplink resource is associated with a transmission time of the second uplink resource. The first uplink resource can be understood as one or more transmission opportunities on a periodic or semi-persistent PUCCH or PUSCH resource. For example, a network device configures a periodic or semi-persistent reporting resource (PUCCH or PUSCH resource) to carry event-triggered measurement results. When an event occurs, the terminal device sends a first uplink signaling at a transmission opportunity of the second uplink resource. Then, the terminal device can send the event-triggered measurement results at a transmission opportunity of the reporting resource associated with the transmission opportunity of the second uplink resource. This transmission opportunity of the reporting resource is the aforementioned first uplink resource. This transmission opportunity of the reporting resource can be the first transmission opportunity of the reporting resource after the k-th duration of the transmission opportunity of the aforementioned second uplink resource. The k-th duration can be x ms, y time slots, etc., without limitation. The first uplink signaling can be sent on the second uplink resource only if there is an event-triggered measurement result; or, the terminal device can also send the first uplink signaling on the second uplink resource, indicating whether there is an event-triggered measurement result that needs to be sent through the second uplink resource. Next, the network device sends beam indication signaling to the terminal device, and correspondingly, the terminal device receives beam indication signaling from the network device. Therefore, the first condition in this application includes at least one of the following:

[0439] Condition C1: The terminal device receives beam indication signaling six hours after sending the first uplink signaling and before the first uplink resource;

[0440] Condition C2: The terminal device receives a beam indication signaling six hours after sending the first uplink signaling, and the first uplink resource is located seven hours after the terminal device receives the beam indication signaling.

[0441] The first uplink signaling in conditions C1 and C2 above indicates that the second uplink resource has an event-triggered measurement result and / or indicates that an event has occurred.

[0442] In this way, the terminal device can choose not to send event-triggered measurement results on the first uplink resource, thereby reducing the overhead of the uplink resource.

[0443] The phrase "six hours after the terminal device sends the first uplink signaling" can be understood as "the terminal device sending the first uplink signaling and experiencing the sixth hour."

[0444] The phrase "after the terminal device receives the beam indication signaling for the seventh time" can be understood as "the moment the terminal device receives the beam indication signaling and after the seventh time has elapsed".

[0445] Optionally, the sixth duration can be configured by the network device, determined by the capabilities of the terminal device, or related to any one or more of the provisions in the protocol. For example, the sixth duration may be related to the duration of the network device processing the first uplink signaling, or to the UE's RF capabilities for switching uplink and downlink. The sixth duration includes N time units, where N is an integer greater than or equal to 0. For example, this time unit may be an hour, minute, second, millisecond, microsecond, nanosecond, frame, subframe, slot, symbol, sampling time (Ts), or basic time unit (Tc), etc. Regarding the description of the seventh duration, the seventh duration includes M time units, where M is an integer greater than or equal to 0. Optionally, the seventh duration may be related to the time the terminal device processes beam indication signaling. The rest is similar to the description of the sixth duration and will not be repeated here.

[0446] Optionally, assume that the sixth duration includes 0 time units and the seventh duration includes 0 time units.

[0447] The description of condition C1 can be replaced as: The terminal device receives beam indication signaling after sending the first uplink signaling and before the first uplink resource;

[0448] Then the description of condition C2 can be replaced as follows: After the terminal device sends the first uplink signaling, it receives the beam indication signaling, and the first uplink resource is located after the terminal device receives the beam indication signaling.

[0449] Optional, the implementation example three shown above is suitable for... Figure 13The corresponding Mode B reporting method. This can be understood as the network device configuring the terminal device with the Mode B reporting method, or in other words, the measurement report corresponding to the event-triggered measurement result is configured with the Mode B reporting method.

[0450] Optional, Figure 11 The illustrated embodiment also includes step 201a. Step 201a may be performed before step 201.

[0451] 201a. The terminal device sends capability information to the network device. Correspondingly, the network device receives the capability information from the terminal device.

[0452] The capability information includes at least one of the following:

[0453] Does the terminal device support the ability to report events?

[0454] Event-triggered reporting methods supported by the terminal device;

[0455] The terminal device supports the reporting of one or more corresponding events triggered by events.

[0456] The aforementioned event-triggered reports can be event-triggered beam reporting, event-triggered CSI reporting, event-triggered beam measurement result reporting, event-triggered measurement result reporting, event-triggered interference measurement reporting, etc., and are not limited to these. As an example, event triggering or event occurrence can also be referred to as UE triggering or UE-initiated, etc., so event-triggered reporting can also be called UE-triggered reporting or UE-initiated reporting.

[0457] One possible implementation is that whether a terminal device supports event-triggered reporting is indicated by at least one bit. For example, whether a terminal device supports event-triggered reporting can be indicated by 1 bit: if the bit is set to "0", it indicates that the terminal device supports event-triggered reporting; if the bit is set to "1", it indicates that the terminal device does not support event-triggered reporting. It should be understood that the above is merely an illustrative example and is not intended to be limiting.

[0458] Another possible implementation is to indicate whether the terminal device supports event-triggered reporting by reporting whether it does so. For example, if the terminal device does not report that it does not support event-triggered reporting, it can be assumed that the terminal device supports event-triggered reporting. Or, for example, if the terminal device does not report that it supports event-triggered reporting, it can be assumed that the terminal device does not support event-triggered reporting.

[0459] The above is an illustrative example, and the embodiments of this application are not limited thereto. For example, whether a terminal device supports the ability to trigger event reporting can also be indicated by a specific field. If the capability information includes the specific field, it indicates that the terminal device supports the ability to trigger event reporting; if the first indication information does not include the specific field, it indicates that the terminal device does not support the ability to trigger event reporting.

[0460] Optionally, the capability information includes an index of each event supported by the terminal device; or, the capability information includes an index of each event table supported by the terminal device, where an event table includes one or more events; or, the capability information includes the number of events supported by the terminal device.

[0461] Optional, Figure 11 The illustrated embodiment also includes step 201b. Step 201b may be performed before step 201.

[0462] 201b. The network device sends configuration information to the terminal device. Correspondingly, the terminal device receives the configuration information from the network device.

[0463] The network device sends configuration information to the terminal device, which is used to configure one or more events for the terminal device. For a description of the events, please refer to the previous introductions of events 1 to 11, which will not be repeated here.

[0464] Optionally, the configuration information includes the indexes corresponding to the one or more events (such as events 1 to 11 mentioned above). Alternatively, the configuration information includes an event table that includes the indexes corresponding to the one or more events.

[0465] Optionally, the network device sends an activation signaling message to the terminal device. Correspondingly, the terminal device receives the activation signaling message from the network device. This activation signaling message is used to activate some or all of the events in the one or more events.

[0466] Further, optionally, the network device sends a deactivation signaling message to the terminal device. Correspondingly, the terminal device receives the deactivation signaling message from the network device. This deactivation signaling message is used to deactivate some or all of the events in the one or more events.

[0467] It should be noted that, if Figure 11 The illustrated embodiment includes steps 201a and 201b, and there is no fixed execution order between steps 201a and 201b. In this application, step 201a can be executed first, followed by step 201b; or step 201b can be executed first, followed by step 201a; or, depending on the situation, steps 201a and 201b can be executed simultaneously. This application does not limit the specific execution order.

[0468] Optionally, the configuration information can also be used to configure information related to event-triggered reporting. For example, the event-triggered reporting configuration can be a CSI report configuration (CSI-ReportConfig), which configures an indication (e.g., reportConfigType is configured as EventTriggered) to indicate that the report is configured for event-triggered reporting. Alternatively, if the CSI-ReportConfig contains event-related information, such as the event index and the corresponding threshold, it indicates that the report is configured for event-triggered reporting. Or, the event-triggered reporting configuration can be configured through a dedicated information element (IE), such as L1-EventTriggered-CSI-ReportConfig or UEInitiated-CSI-ReportConfig.

[0469] For example, the configuration information includes one or more of the following, or is associated with one or more of the following:

[0470] 1. One or more cell information entries indicating which cell(s) the reference signal resource associated with the report belongs to. Examples include a serving cell index or identifier, which can be a primary cell (Pcell), a secondary cell (Scell), or a primary secondary cell (PScell). A Pcell can also be called a cell on the primary component carrier (PCC), and an Scell ​​can be called a cell on the secondary component carrier (SCC). Another example is an additional PCI, which is the neighboring cell of the serving cell, also known as the physical cell identifier (PCI) of a non-serving cell; it can also be a candidate cell index; a component carrier (CC) index; or a PCI.

[0471] 2. Supports one or more event information entries. These event information entries are used to configure one or more events for the terminal device. For a description of the events, please refer to the relevant introduction in step 201 above; it will not be repeated here. If the configuration information is associated with only one cell, the one or more event information entries correspond to that cell. If the configuration information is associated with multiple cells, one or more event information entries can be configured independently for each cell, or multiple cells can be associated with the same one or more event information entries.

[0472] 3. Reference signal measurement resources corresponding to one or more events. These reference signal measurement resources can be configured individually for each event, or the same reference signal measurement resource can be configured for multiple events. Specific reference signal resources can refer to the reference signals corresponding to the serving beam and the new beam mentioned above. Reference signal resources can be explicitly configured or implicitly determined. Similarly, if this configuration information is associated with only one cell, the reference signal measurement resource corresponds to that cell. If this configuration information is associated with multiple cells, each cell independently configures one or more reference signal measurement resources corresponding to each event.

[0473] 4. Event-triggered reporting resources, equivalent to the first uplink resources of this application, are used to carry the reporting of beam measurement results triggered by the event. Specifically, event-triggered reporting resources can be any one of the following: PUCCH resources, PUSCH resources, pre-configured PUSCH resources, event-triggered reporting resources, UE-triggered reporting resources, event-triggered channel resources, event-triggered uplink resources, dynamically scheduled PUSCH resources, periodic PUCCH resources, aperiodic PUSCH resources, semi-persistent PUCCH resources, or semi-persistent PUSCH resources. Similarly, if this configuration information is associated with one cell, then this reporting resource corresponds to one cell; if this configuration information is associated with multiple cells, only one event-triggered reporting resource can be configured, i.e., each cell corresponds to the same event-triggered reporting resource, or event-triggered reporting resources can be configured separately for each cell.

[0474] 5. A scheduling request resource or reporting indication resource (equivalent to the second uplink resource in this application) is used to carry indication information of an event occurrence (e.g., the first uplink signaling in this application). This indication information is used to indicate to the network device that it is necessary to report event-triggered measurement results and / or that an event has occurred, or to request reporting resources to carry event-triggered measurement results. Similarly, if the configuration information is associated with one cell, the scheduling request or indication resource corresponds to one cell; if the configuration information is associated with multiple cells, only one scheduling request resource or reporting indication resource can be configured, i.e., each cell corresponds to the same scheduling request resource or reporting indication resource, or each cell can be configured with a separate scheduling request resource or reporting indication resource.

[0475] 6. A reporting quantity for one or more events, used to indicate what the event-triggered measurement results reported by the terminal device to the network device should include. The reporting quantity for each event can be network configuration or protocol-defined. The reporting quantity can be one or more of the following: event index, cell index, current beam reference signal index, new beam reference signal index, L1-RSRP, L1-SINR, etc. Optionally, it may also include the number of reports corresponding to the reporting quantity. Optionally, the reporting quantity may include one or more of the event-triggered measurement results described in step 201 of this application.

[0476] 7. Event-triggered reporting methods. For example, the two reporting methods involved in this application will be described below.

[0477] Reporting Method 1 (equivalent to) Figure 12 (Corresponding to Mode A reporting method): The terminal device sends a first uplink signaling message to the network device. This first uplink signaling message requests the network device to schedule a first uplink resource for the terminal device, and this first uplink signaling message is carried on a second uplink resource. After receiving the first uplink signaling message from the terminal device, the network device sends a first scheduling signaling message to the terminal device, and the terminal device receives the first scheduling signaling message from the network device. This first scheduling signaling message is used to indicate or schedule the first uplink resource. Then, the terminal device sends a measurement result carrying an event-triggered measurement to the network device, and the network device receives the event-triggered measurement result from the terminal device. This event-triggered measurement result is carried on the aforementioned first uplink resource.

[0478] It should be noted that this reporting method one applies to the first conditions provided in Implementation Example 1 and Implementation Example 2 in step 203 above.

[0479] Reporting Method Two (equivalent to) Figure 13 (Corresponding Mode B reporting method): The network device pre-configures and activates the first uplink resource for the terminal device, or the network device pre-configures the first uplink resource for the terminal device (either activation-free or already activated). The terminal device sends a first uplink signaling message to the network device. This first uplink signaling message notifies the network device that event-triggered measurement results will be carried on the first uplink resource, and the first uplink signaling message is carried on the second uplink resource. Next, the network device sends a beam indication signaling message to the terminal device, and the terminal device receives the beam indication signaling message from the network device.

[0480] It should be noted that this second reporting method applies to the first condition provided in the implementation example three of step 203 above.

[0481] Please see Figure 17 , Figure 17 This is a schematic diagram illustrating another possible implementation of the communication method in this application. It should be understood that this application uses network devices and terminal devices as examples to illustrate the method, but this application does not limit the execution entities of this interaction. For example, Figure 17 The network device mentioned can also refer to chips, baseband chips, modem chips, system-on-chip (SoC) chips containing modem cores, system-in-package (SIP) chips, communication modules, chip systems, processors, logic modules, or software within network devices. In this application, the term "network device" can refer to the network device itself, or to chips, communication modules, integrated circuits, processors, logic modules, or software within the network device used to implement the communication methods provided in this application; no specific limitation is made in this application. Figure 17 The terminal device mentioned can also refer to chips, baseband chips, modem chips, SoC chips containing modem cores, SIP chips, communication modules, chip systems, processors, logic modules, or software within terminal devices. In this application, the term "terminal device" can refer to the terminal device itself, or to chips, communication modules, integrated circuits, processors, logic modules, or software within the terminal device used to implement the communication method provided in this application; no specific limitation is made in this application.

[0482] like Figure 17 As shown, the communication method of this application includes, but is not limited to, steps 501 to 502.

[0483] 501. The terminal device sends a first uplink signaling message to the network device. Correspondingly, the network device receives the first uplink signaling message from the terminal device.

[0484] The first uplink signaling is used to request the network device to schedule a first uplink resource for the terminal device and / or indicate the occurrence of an event, wherein the first uplink resource is used to carry the event-triggered measurement results of the terminal device; or, the first uplink signaling is used to notify the network device that the event-triggered measurement results are carried in the first uplink resource and / or indicate the occurrence of an event.

[0485] In this application, step 501 is similar to the aforementioned step 201. Please refer to the description of the aforementioned step 201 for details, which will not be repeated here.

[0486] 502. If the second condition is met, the terminal device does not expect to receive the first scheduling signaling or the beam indication signaling. The first scheduling signaling is used to indicate the first uplink resource, and the beam indication signaling is used to indicate the serving beam of the terminal device.

[0487] If the second condition is met, the terminal device does not expect to receive the first scheduling signaling or beam indication signaling. In other words, if the second condition is met, the network device will not send the first scheduling signaling or beam indication signaling to the terminal device.

[0488] Optionally, if the second condition is not met, the terminal device may receive the first scheduling signaling or beam indication signaling. In other words, if the second condition is not met, the network device may send the first scheduling signaling or beam indication signaling to the terminal device.

[0489] In this application, if the second condition is met, the terminal device does not expect to receive the first scheduling signaling or beam indication signaling. This avoids the situation where beam indication signaling is received but the event condition is not met, yet the measurement result is still reported based on the event trigger, or where the measurement result is invalid, thus avoiding a waste of reporting resources.

[0490] Optionally, the phrase "the terminal device does not expect to receive the first scheduling signaling or beam indication signaling" in this application can be replaced with "the terminal device does not receive the first scheduling signaling or beam indication signaling", or "the terminal device does not parse the first scheduling signaling or beam indication signaling", or "the terminal device ignores the first scheduling signaling or beam indication signaling".

[0491] The descriptions of the first scheduling signaling or beam indication signaling in steps 202 and 203, as well as the descriptions associated with the first scheduling signaling and beam indication, also apply to step 502, and will not be repeated here.

[0492] In step 502 of this application, the second condition can be implemented in various ways, which will be illustrated below with some implementation examples. Other implementation methods are also applicable to this application, and this application does not impose any specific limitations.

[0493] Example 4: The terminal device sends a first uplink signaling message to the network device via the second uplink resource. Then, the network device sends a beam indication signaling message to the terminal device, and correspondingly, the terminal device receives the beam indication signaling message from the network device. If a second condition is met, the terminal device does not expect to receive the first scheduling signaling message. The second condition includes at least one of the following:

[0494] Condition D1: The terminal device receives the beam indication signaling before the eighth time interval;

[0495] Condition D2: The terminal device receives the beam indication signaling after the ninth time interval and before the eighth time interval;

[0496] Condition D3: After ten hours of the terminal device sending the first uplink signaling and before eight hours of receiving the beam indication signaling;

[0497] Condition D4: After the terminal device receives the beam indication signaling for the ninth time period, and has not retransmitted or sent the first uplink signaling to the network device.

[0498] The phrase "before the eighth duration of the beam indication signaling received by the terminal device" can be understood as "the time when the terminal device receives the beam indication signaling plus the time when the eighth duration is located".

[0499] The phrase "after the ninth duration of receiving the beam indication signaling and before the eighth duration" can be understood as "the moment when the terminal device receives the beam indication signaling and after the ninth duration has elapsed, and before the moment when the beam indication signaling is received plus the moment when the eighth duration is located".

[0500] The phrase "after the terminal device receives the beam indication signaling for the ninth time" can be understood as "the moment the terminal device receives the beam indication signaling and after the ninth time has elapsed".

[0501] The phrase "after the terminal device receives the beam indication signaling for the ninth time period, and does not retransmit or send the first uplink signaling to the network device" can be understood as "after the terminal device receives the beam indication signaling for the ninth time period, the terminal device does not retransmit or send the first uplink signaling to the network device".

[0502] In this way, after receiving the beam indication signaling, the terminal device can avoid receiving the first scheduling signaling, and thus avoid sending event-triggered measurement results on the first uplink resource indicated by the first scheduling signaling. This avoids resource waste.

[0503] Optionally, the eighth duration can be configured by the network device, determined by the capabilities of the terminal device, or related to any one or more of the provisions in the protocol. For example, the eighth duration can be the minimum time interval between beam indication signaling and the first scheduling signaling configured by the network device. The eighth duration includes N time units, where N is an integer greater than or equal to 0. For example, this time unit can be an hour, minute, second, millisecond, microsecond, nanosecond, frame, subframe, slot, symbol, sampling time (Ts), or basic time unit (Tc), etc. Regarding the description of the ninth and tenth durations, the ninth duration includes M time units, where M is an integer greater than or equal to 0. Optionally, the ninth duration can be related to the time when the terminal device processes the beam indication signaling; the tenth duration includes X time units, where X is an integer greater than or equal to 0. Optionally, the tenth duration can be related to the time when the network device processes the first uplink signaling. The rest are similar to the description of the eighth duration mentioned above, and will not be repeated here.

[0504] Optionally, assume that the eighth duration includes 0 time units, the ninth duration includes 0 time units, and the tenth duration includes 0 time units.

[0505] The descriptions of conditions D1 and D2 can then be replaced with: after the terminal device receives the beam indication signaling;

[0506] Then the description of condition D3 can be replaced as: After the terminal device sends the first uplink signaling, the terminal device receives the beam indication signaling, and after receiving the beam indication signaling;

[0507] The description of condition D4 can be replaced with: After the terminal device receives the beam indication signaling, it does not retransmit or send the first uplink signaling to the network device.

[0508] Example 5: The terminal device sends a first uplink signaling to the network device via a second uplink resource. Then, the network device sends a first scheduling signaling to the terminal device, and correspondingly, the terminal device receives the first scheduling signaling from the network device. If a second condition is met, the terminal device does not expect to receive beam indication signaling. The second condition includes at least one of the following:

[0509] Condition E1: Eleventh time before the terminal device sends the first uplink signaling;

[0510] Condition E2: After the terminal device sends the first uplink signaling for twelfth time interval and before the eleventh time interval;

[0511] Condition E3: After the terminal device sends the first uplink signaling for twelfth time and before the first uplink resource.

[0512] The phrase "before the eleventh duration of the terminal device sending the first uplink signaling" can be understood as "the time before the terminal device sends the first uplink signaling plus the time of the eleventh duration".

[0513] The phrase "after the twelfth duration of the terminal device sending the first uplink signaling and before the eleventh duration" can be understood as "after the terminal device sends the first uplink signaling and after the twelfth duration has elapsed, and before the time when the first uplink signaling was sent plus the time when the eleventh duration is located".

[0514] The phrase "after the twelfth hour since the terminal device sent the first uplink signaling" can be understood as "the moment the terminal device sent the first uplink signaling and after the twelfth hour has elapsed".

[0515] The phrase "after the terminal device sends the first uplink signaling" can be understood as "after the time domain resources for the terminal device to send the first uplink signaling" or "after the terminal device receives the symbol for sending the first uplink signaling".

[0516] In this context, the network device indicates the first uplink resource, and the terminal device obtains information about the time-domain and frequency-domain resources within the first uplink resource. Therefore, the description "before the first uplink resource" can be replaced with "before the time-domain resources in the first uplink resource" or "before the symbol containing the first uplink resource".

[0517] In this way, after receiving the first scheduling signaling, the terminal device can avoid receiving beam indication signaling, thereby preventing beam indication signaling from interfering with the terminal device's reporting of event-triggered measurement results.

[0518] Optionally, the eleventh duration can be configured by the network device, determined by the capabilities of the terminal device, or related to any one or more of the provisions in the protocol. For example, the eleventh duration can be the maximum time interval between the first uplink signaling and the first scheduling signaling configured by the network device. For example, the twelfth duration is related to the duration for the network device to process the first uplink signaling, or to the UE's RF capability for switching uplink and downlink, etc. The eleventh duration includes N time units, where N is an integer greater than or equal to 0. For example, this time unit can be an hour, minute, second, millisecond, microsecond, nanosecond, frame, subframe, slot, symbol, sampling time (Ts), or basic time unit (Tc), etc. The twelfth duration includes M time units, and the rest are similar to the description of the aforementioned eleventh duration, and will not be repeated here.

[0519] Optionally, it is assumed that the eleventh duration includes 0 time units and the twelfth duration includes 0 time units.

[0520] The descriptions of conditions E1 and E2 can then be replaced with: after the terminal device sends the first uplink signaling.

[0521] The description of condition E3 can then be replaced with: after the terminal device sends the first uplink signaling and before the first uplink resource.

[0522] Optional, Figure 17 The illustrated embodiment also includes step 501a. Step 501a may be performed before step 501.

[0523] In this application, step 501a is similar to the aforementioned step 201a. For details, please refer to the description of the aforementioned step 201a, which will not be repeated here.

[0524] Optional, Figure 17 The illustrated embodiment also includes step 501b. Step 501b may be performed before step 501.

[0525] In this application, step 501b is similar to the aforementioned step 201b. For details, please refer to the description of the aforementioned step 201b, which will not be repeated here.

[0526] In one possible implementation, after the thirteenth time period and before the fourteenth time period after the terminal device receives the beam indication signaling, the terminal device performs at least one of the following operations:

[0527] Terminal devices can cancel, clear, or discard measurement results related to the event;

[0528] The terminal device does not send the first uplink signaling, or in other words, the terminal device does not send the second uplink resource;

[0529] The terminal device will reset the counters and timers related to the event to zero, or in other words, the terminal device will re-determine whether the event has occurred, or the terminal device will restart the event determination process.

[0530] The terminal device ignores the first scheduling signaling.

[0531] The phrase "after the thirteenth duration and before the fourteenth duration when the terminal device receives the beam indication signaling" can be understood as "the moment when the terminal device receives the beam indication signaling and after the thirteenth duration has elapsed, and before the moment when the beam indication signaling is received plus the moment when the fourteenth duration is located".

[0532] Optionally, the thirteenth and / or fourteenth durations can be configured by the network device, determined by the capabilities of the terminal device, or related to any one or more of the provisions in the protocol. For example, the thirteenth duration is related to the duration for the terminal device to process beam indication signaling. The fourteenth duration can be the minimum time interval between the beam indication signaling configured by the network device and the first scheduling signaling. The thirteenth duration includes N time units, where N is an integer greater than or equal to 0. For example, this time unit can be an hour, minute, second, millisecond, microsecond, nanosecond, frame, subframe, slot, symbol, sampling time (Ts), or basic time unit (Tc), etc. The fourteenth duration includes M time units, and the rest are similar to the description of the thirteenth duration above, and will not be repeated here.
