Description

Methods and apparatus for sending and receiving uplink reports Technical Field

[0001] The embodiments of this application relate to the field of communication technology. Background Technology

[0002] 5G NR supports Channel State Information (CSI) reporting. For example, a CSI report may include at least one of the following: CSI-RS Resource Indicator (CRI), SSB Resource Indicator (SSBRI), Layer 1 Reference Signal Received Power (L1-RSRP), and Layer 1 Signal-to-Interference-plus-Noise Ratio (L1-SINR), i.e., beam-related reporting. The terminal device sends beam reports to the network device, which can then perform beam management based on these reports, for example, indicating a better beam for the terminal device.

[0003] When a terminal device sends a CSI report is determined by the network device; that is, the report is scheduled by the network device. The network device can be configured to send periodic CSI reports, thus the terminal device sends CSI reports periodically; the network device can be configured to send semi-persistent CSI reports, which the terminal device sends periodically after being activated by the network device; the network device can be configured to send a non-periodic CSI reports, which the terminal device sends once after being triggered by the network device. The CSI report includes measurement results specific to the serving cell.

[0004] Version 17 (Rel-17) adds support for Inter Cell Beam Management (ICBM). In ICBM, CSI reports can include measurement results for non-serving cells, allowing network devices to instruct terminal devices to use the beam of a non-serving cell without the terminal device switching to the non-serving cell.

[0005] Rel-18 supports Layer 1 / L2 Triggered Mobility (LTM), and adds support for LTM CSI reports. In LTM, terminal devices can send LTM CSI reports. Rel-18 LTM CSI reports include SSBRI and L1-RSRP. Unlike traditional CSI reports, LTM CSI reports include measurement results for candidate cells. Network devices can use this information to determine the beam to use in the candidate cell for the terminal device and indicate the beam to the terminal device before handover, enabling the terminal device to quickly apply the appropriate beam for data transmission after handover. In other words, in LTM, the terminal device hands over to a candidate cell and uses the candidate cell's beam after handover. Similarly, terminal devices can send LTM CSI reports periodically, semi-persistently, or aperiodically. LTM CSI reports are also part of the network device scheduling reports.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application.

[0007] Summary of the Invention

[0008] The inventors have discovered that event-triggered reporting (also known as event-driven reporting or terminal device-initiated reporting) will be introduced in the upcoming Rel-19. More specifically, further enhancements to CSI and LTM CSI reports will be introduced, supporting event-triggered CSI and event-triggered LTM CSI reports. Event-triggered CSI and event-triggered LTM CSI reports correspond to traditional CSI and LTM CSI reports, respectively. For simplicity, the term "event-triggered report" will be used uniformly in the following description; that is, the event-triggered report in the embodiments of this application can be either an event-triggered CSI report or an event-triggered LTM CSI report.

[0009] Unlike traditional reporting, event-triggered reporting determines when the terminal device sends a report, i.e., it's triggered by an event. In other words, the terminal device only sends reports when necessary, allowing for more timely reporting. Furthermore, by avoiding unnecessary reporting, reporting overhead is reduced. How to support event-triggered reporting is a problem that needs to be solved.

[0010] To address at least one of the above-mentioned problems, embodiments of this application provide a method and apparatus for sending and receiving uplink reports.

When a terminal device has both event-triggered reports and network scheduling reports to send, the terminal device selects one report to send. This avoids ambiguity between the terminal device and the network device regarding which reports to actually send, thereby achieving timely and reliable transmission of uplink reports.

[0079] Figure 1 is a schematic diagram of a communication system according to an embodiment of this application, illustrating the case of a terminal device and a network device as examples. As shown in Figure 1, the communication system 100 may include a network device 101 and terminal devices 102 and 103. For simplicity, Figure 1 only illustrates the case of two terminal devices and one network device, but the embodiments of this application are not limited to this.

[0080] In this embodiment of the application, network device 101 and terminal devices 102 and 103 can transmit existing services or services that can be implemented in the future. For example, these services may include, but are not limited to: enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0081] It is worth noting that Figure 1 shows that both terminal devices 102 and 103 are within the coverage area of ​​network device 101, but this application is not limited to this. Both terminal devices 102 and 103 may be outside the coverage area of ​​network device 101, or one terminal device 102 may be within the coverage area of ​​network device 101 while the other terminal device 103 may be outside the coverage area of ​​network device 101.

[0082] In the embodiments of this application, the signaling may be, for example, Radio Resource Control (RRC) signaling; for example, referred to as an RRC message, including MIB, system information, dedicated RRC messages; or referred to as an RRC information element. The signaling may also be, for example, Medium Access Control (MAC) signaling; or referred to as a MAC control element. However, this application is not limited to these.

[0083] In the following description, without confusion, the terms "PDCCH" and "Physical Downlink Control Channel" or "Downlink Control Information" are used interchangeably, as are the terms "PDSCH" and "Physical Downlink Data Channel" or "Downlink Data". Furthermore, transmitting or receiving a PDCCH can be understood as transmitting or receiving downlink control information carried by the PDCCH; transmitting or receiving a PDSCH can be understood as transmitting or receiving downlink data carried by the PDSCH.

[0084] The terms "PUCCH" and "Physical Uplink Control Channel" or "Uplink Control Information" are interchangeable, as are the terms "PUSCH" and "Physical Uplink Data Channel" or "Uplink Data." Furthermore, transmitting or receiving a PUCCH can be understood as transmitting or receiving downlink control information carried by the PUCCH; transmitting or receiving a PUSCH can be understood as transmitting or receiving downlink data carried by the PUSCH.

[0085] The terms "PRACH" and "Physical Random Access Channel" or "Random Access Information" are interchangeable. Furthermore, transmitting or receiving PRACH can be understood as transmitting or receiving random access information carried by the PRACH. In the embodiments of this application, the terms "indication," "activation," and "trigger" are interchangeable, or can be used in combination.

[0086] Terminal devices need to send event-triggered reports on certain time-frequency resources. The determination of resources requires corresponding information exchange. For example, the terminal device may send a first message to request dynamically scheduled resources or to notify whether semi-statically configured resources are actually being used.

[0087] Figure 2 is a schematic diagram of an event-triggered report according to an embodiment of this application. As shown in Figure 2, the first resource used to send the first message is a pre-configured (RRC signaling configured) periodic physical uplink control channel (PUCCH) resource (only one period is shown), and the second resource used to send the event-triggered report is a DCI (downlink control information) scheduled resource.

[0088] As shown in Figure 2, the terminal device measures one or more reference signals (RS1 to RS4). After detecting an event that triggers a report, it requests the resources needed to send the report (i.e., requests the second resource) from the network device by sending a first message. After receiving the DCI (Direct Access Control Information), it sends the report on the second resource scheduled by the DCI. The report is carried by the UCI (Upper Uplink Control Information), which is multiplexed and transmitted in the Physical Uplink Shared Channel (PUSCH) indicated by the DCI. Not shown in Figure 2, the DCI can also schedule the PUCCH, allowing the UCI to be sent via the PUCCH. The report can be carried by either the PUSCH or the PUCCH; the first message is carried by the PUCCH. Here, "resources" refers to time-frequency resources.

[0089] This application does not limit the events that trigger the report. For example, the event could be that the measurement result (L1-RSRP) of a new beam (one of RS1 to RS4) is higher than the measurement result of the current beam by a certain value, or that the measurement result of the current beam is lower than a certain value. This application does not limit the content of the report. For example, the report includes a reference signal index and the L1-RSRP measured based on that reference signal; the report may include one or more reference signal indices and L1-RSRPs. The report is used to report beam information, and its purpose is to report the beam and the measurement results for that beam. The report can also be replaced by a beam report.

[0090] Figure 3 is another schematic diagram of an event-triggered report according to an embodiment of this application. As shown in Figure 3, the first resource used to send the first message is a pre-configured periodic PUCCH resource (only one period is shown), and the second resource used to send the report (PUSCH or PUCCH, with PUSCH as an example in the figure) is a pre-configured periodic resource (only one period is shown). There is an association between the first resource and the second resource, for example, one first resource is associated with one second resource.

[0091] As shown in Figure 3, the terminal device measures one or more reference signals (RS1 to RS4). After detecting an event that triggers a report, it notifies the network device that a report is being transmitted on the second resource associated with the first message (first resource) by sending a first message. Thus, without receiving DCI, the report can be sent directly on the associated second resource.

[0092] Conversely, if the terminal device does not detect an event, it can refrain from sending the first message. This notifies the network device that no report transmission exists on the second resource associated with the first message, allowing the network device to schedule other terminal devices to transmit on the second resource, thus avoiding waste of the pre-configured second resource in a semi-static manner. Without loss of generality, if the terminal device does not detect an event, it can also send the first message, but the content of this first message will differ from the previous one. In this case, the first message will notify the network device that no report transmission exists on the second resource associated with the first message.

[0093] When a terminal device needs to send multiple reports, how to send these reports is a problem that needs to be solved. These multiple reports may include multiple event-triggered reports, or they may include event-triggered reports and network scheduling reports. The following examples illustrate the situation where a terminal device needs to send multiple reports.

[0094] First aspect of the embodiments

[0095] This application provides a method for sending uplink reports, described from the perspective of the terminal device.

[0096] Figure 4 is a schematic diagram of an uplink report transmission method according to an embodiment of this application. As shown in Figure 4, the method includes:

[0097] 401, The terminal device determines that the first report meets the first triggering condition;

[0098] 402, the terminal device sends a first physical uplink control channel (PUCCH);

[0099] 403, the terminal device determines a first uplink channel based on the received first downlink control information (DCI), wherein the first uplink channel is indicated by the first DCI, or the terminal device determines the first uplink channel based on the first PUCCH, wherein the first uplink channel is associated with the first PUCCH;

[0100] 404. Before the terminal device sends the first uplink channel, if it is determined that the second report meets the second triggering condition, the terminal device determines one report from the first report and the second report, and sends the determined report on the first uplink channel.

[0101] In the embodiments of this application, "event-triggered report" is also known as "event-triggered report". "Event-triggered" can be replaced with "UE-initiated" or "event-driven". This application is not limited thereto.

[0102] In the embodiments of this application, "before sending the first uplink channel" means, for example, "within the time period no earlier than determining that the first report satisfies the first triggering condition and earlier than sending the first uplink channel," but this application is not limited thereto.

[0103] In this embodiment, the terminal device may also send a first report under the following circumstances: the second report does not exist, the second report does not meet the second triggering condition, or the second report does not meet the second triggering condition before sending the first uplink channel, etc. That is, when the condition "the terminal device determines that the second report meets the second triggering condition before sending the first uplink channel" is not met, the terminal device sends a first report on the first uplink channel. This application is not limited thereto.

[0104] It is worth noting that Figure 4 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 4 above.

[0105] Figure 5 is an example diagram of multiple uplink reports according to an embodiment of this application. For example, as shown in Figure 5, the terminal device measures the reference signal (SSB or CSI-RS) in the first measurement reference signal set, and determines that report x (first report) meets the first triggering condition based on the measurement result (L1-RSRP). The terminal device sends a PUCCH (first PUCCH, which can carry one or more bits of information) on the most recent PUCCH transmission timing (transmission timing k), that is, notifies the network device that it has a report to send and requests the network device for resources to send the report. The PUCCH transmission timing is configured by RRC signaling. After receiving the PUCCH at PUCCH transmission timing k, the network device sends a DCI (first DCI) to indicate the resources for sending the report to the terminal device, that is, to indicate the resources where the uplink channel (first uplink channel) is located. The terminal device receives the DCI and determines the resource location of the uplink channel. The DCI can be an uplink DCI (e.g., DCI format 0_1 ​​or 0_2) or a downlink DCI (e.g., DCI format 0_1 ​​or 0_2). 1_1 or 1_2), the uplink channel can be PUSCH or PUCCH; the terminal device sends a report x on the uplink channel, the report content includes the index of the measurement reference signal and the L1-RSRP of the measurement reference signal.

[0106] A report meeting the trigger condition indicates that the event associated with the report meets the trigger condition; it can also be referred to as an event meeting the trigger condition. For example, a report is associated with an event. When the event meets the trigger condition, the report associated with that event becomes a report meeting the trigger condition (the triggered report), and the terminal device sends the report associated with that event. This application does not limit the definition of an event. For example, an event (the trigger condition of an event) is defined as: the measurement result of at least one new beam is higher than the measurement result of the current beam by a certain threshold value (or the number of times it exceeds a certain threshold value exceeds a certain number); for example, the measurement of the new beam refers to the measurement of the reference signal in the measurement reference signal set, and the measurement of the current beam refers to the measurement of the source reference signal (or the SSB quasi-co-addressable with the source reference signal) of the currently applied TCI state (downlink TCI state or joint TCI state); for example, the measurement result can be L1-RSRP or filtered L1-RSRP. The threshold value can be configured by RRC signaling; for example, independent threshold values ​​can be configured for CSI-RS-based measurements and SSB-based measurements respectively.

[0107] The process from generating the triggered report x to sending the triggered report x has been described above. However, the terminal device may generate multiple triggered reports. For example, the terminal device determines that the second report meets the second trigger condition during a period not earlier than determining that the first report meets the first trigger condition and earlier than sending the first uplink channel. More specifically, the report x becomes a report that meets the first trigger condition at time t1, and the terminal device starts to send the report on the uplink channel at time t2. During the period from t1 ≤ t < t2, the report y (the second report) may become a report that meets the second trigger condition. The terminal device has one opportunity to send a report (one uplink channel), but the terminal device has two triggered reports (report x and report y) that need to be sent. At this time, it is necessary to clarify the behavior of the terminal device.

[0108] In this embodiment, the terminal device selects one report from report x and report y to send on the uplink channel. By selecting one report, the terminal device consistently sends only one report on the uplink channel. The terminal device indicates which report is being sent in the sent report, or the network device indicates which report to send via DCI; therefore, selecting one report for transmission does not cause any ambiguity on the network device side. This embodiment does not limit the reasons for generating the first report that meets the first triggering condition and the second report that meets the second triggering condition. For example, multiple events are defined, with report x associated with a first event and report y associated with a second event. When the first event meets its trigger condition, report x meets the first trigger condition; when the second event meets its trigger condition, report y meets the second trigger condition. For example, the first event is defined as: the measurement result of at least one new beam is higher than the measurement result of the current beam by a certain threshold; the second event is defined as: the measurement result of the current beam is lower than a certain threshold. The threshold values ​​can be configured by RRC signaling, for example, configuring independent threshold values ​​for CSI-RS-based measurements and SSB-based measurements respectively. For example, although only one event is defined (e.g., the first event), the set of measurement reference signals associated with report x is the SSB set (measurements are performed for SSBs and...). The measurement reference signal set associated with report y is the CSI-RS set (measurements and reports are performed on CSI-RS). This can generate more than one triggered report (i.e., triggered report x and triggered report y). More specifically, when the measurement result based on SSB satisfies the condition that the measurement result of at least one new beam is higher than the measurement result of the current beam by a certain threshold, report x becomes a report that satisfies the first triggering condition. When the measurement result based on CSI-RS satisfies the condition that the measurement result of at least one new beam is higher than the measurement result of the current beam by a certain threshold, report y becomes a report that satisfies the second triggering condition. For example, a report can also be associated with multiple different events. When multiple events satisfy their respective triggering conditions, the report becomes a triggered report. In the embodiments of this application, "report" can also be replaced with "event". For example, report x is replaced with event x, and report y is replaced with event y.

[0109] Figure 6 is another example diagram of multiple uplink reports according to an embodiment of this application. For example, the difference between Figure 6 and Figure 5 is that the uplink channel is obtained in a different way. In Figure 5, the resource location of the uplink channel is indicated by the DCI (i.e., the terminal device determines the uplink channel according to the DCI). In Figure 6, the resource location of the uplink channel is configured by RRC signaling, and each PUCCH transmission opportunity is associated with an uplink channel (i.e., the terminal device determines the uplink channel according to the PUCCH).

[0110] When a terminal device sends a PUCCH at a PUCCH transmission time, it is equivalent to notifying the network device that a report sent by the terminal device exists on the uplink channel associated with that PUCCH transmission time (i.e., the transmitted PUCCH). Otherwise, if the terminal device does not send a PUCCH at a PUCCH transmission time, it is equivalent to notifying the network device that no report sent by the terminal device exists on the uplink channel associated with that PUCCH transmission time. The network device can then use the resources of that uplink channel for transmission with other terminal devices, thus avoiding resource waste. After sending a PUCCH at PUCCH transmission time k, the terminal device gains the opportunity to send a report on the uplink channel associated with PUCCH transmission time k. When the terminal device has two triggered reports (report x and report y) to send, the terminal device selects one of reports x and report y to send on the uplink channel.

[0111] Figure 7 is another example diagram of multiple uplink reports according to an embodiment of this application, and Figure 8 is another example diagram of multiple uplink reports according to an embodiment of this application. For example, Figures 7 and 8 provide additional examples of the moment when report y meets the second triggering condition, and the terminal device selects report y to be transmitted on the uplink channel.

[0112] This section assumes the uplink channel is indicated by DCI (i.e., the terminal device determines the uplink channel based on DCI, referred to as Case A). Similarly, this can be extended to the case where the uplink channel is configured by RRC signaling and associated with the PUCCH transmission timing (i.e., the terminal device determines the uplink channel based on PUCCH, referred to as Case B). The terminal device operates in either Case A or Case B. For example, whether the terminal device operates in Case A or Case B can be configured by RRC; for example, the terminal device reports capability information, which includes information on whether the terminal device can operate in Case A and / or Case B. The network device configures the terminal device to operate in Case A or Case B based on the reported capability information. Unless otherwise specified, the embodiments applicable to Case A also apply to Case B. For simplicity, the following embodiments only use Case A as an example.

[0113] In some embodiments, the terminal device determines a report associated with the first PUCCH; after determining that the second report satisfies the second triggering condition, the terminal device sends a second PUCCH, and the terminal device determines a report associated with the second PUCCH.

[0114] For example, once a report meets the triggering conditions, the terminal device will send a PUCCH at the PUCCH transmission time. If only one triggered report exists before a PUCCH, then the PUCCH is associated with that report. However, multiple triggered reports may exist before a PUCCH, in which case it is necessary to specify which report the PUCCH is associated with to avoid missing sending a PUCCH for a particular triggered report.

[0115] Figure 9 is another example diagram of multiple uplink reports according to an embodiment of this application. As shown in Figure 9, before PUCCH transmission timing k, two reports (report x and report y) meet the triggering conditions. The terminal device sends a first PUCCH at PUCCH transmission timing k, considering the first PUCCH to be associated with report x. The terminal device considers that it has initiated a resource request for report x by sending the first PUCCH, that is, it sends a PUCCH for report x at PUCCH transmission timing k. At this time, the terminal device has not yet initiated a resource request for report y. The terminal device sends a second PUCCH at PUCCH transmission timing k+1, considering the second PUCCH to be associated with report y. The terminal device considers that it has initiated a resource request for report y by sending the second PUCCH, that is, it sends a PUCCH for report y at PUCCH transmission timing k+1. Thus, the terminal device has initiated resource requests for all triggered reports. The network device receives the two resource requests and can send two DCIs sequentially to indicate the two uplink channels respectively. The terminal device can complete the transmission of the two reports sequentially on the two uplink channels. Figure 9 only shows the case where the terminal device obtains the uplink channel for the first time. The terminal device selects one of reports, x and y, to send on the uplink channel.

[0116] Figure 10 is another example diagram of multiple uplink reports in an embodiment of this application. The difference between Figure 10 and Figure 9 is that the terminal device considers the first PUCCH sent at PUCCH transmission time k to be associated with report y, and considers the second PUCCH sent at PUCCH transmission time k+1 to be associated with report x.

[0117] For example, a report associated with a PUCCH can be replaced with a pending PUCCH associated with the PUCCH. A pending PUCCH can also be replaced with a pending SR. Each triggered report triggers a pending PUCCH. The terminal device can send a pending PUCCH when it encounters a PUCCH transmission opportunity. A triggered report is associated with a PUCCH sent during a PUCCH transmission opportunity via a pending PUCCH. Since a triggered report triggers a pending PUCCH, in this embodiment, a "report that meets the triggering conditions" can also be replaced with "pending PUCCH" or "pending SR".

[0118] In some embodiments, the terminal device determines a report in the first report and the second report based on at least one of the following: the priority of the first report and the second report; the chronological order of the first report and the second report; the first DCI; the first PUCCH; and the second PUCCH.

[0119] For example, when a terminal device needs to select one report from report x and report y to send, the terminal device makes the selection based on the report's priority. For example, the terminal device selects the report with higher priority, so that the high-priority report can be sent quickly. This application embodiment does not limit how the report priority is defined. For example, a report reporting CSI-RS (measurement reference signal is CSI-RS) takes precedence over a report reporting SSB (measurement reference signal is SSB), or a report reporting SSB takes precedence over a report reporting CSI-RS; for example, the smaller the report ID, the higher the report's priority; the report ID can also be replaced by the report configuration ID, which is configured for each report by RRC signaling; the report ID can also be replaced by the event ID; for example, the smaller the cell ID of the report, the higher the report's priority; the cell where the report is located can be the cell providing the report configuration.

[0120] For example, when a terminal device needs to select one report from report x and report y to send, the terminal device selects the report based on the order in which the trigger conditions are met in time. For example, the terminal device selects the report that meets the trigger conditions first in time, so that the report that triggers first is sent first.

[0121] Figure 11 is another example diagram of multiple uplink reports according to an embodiment of this application, and Figure 12 is another example diagram of multiple uplink reports according to an embodiment of this application. For example, when the terminal device determines the first uplink channel based on the first PUCCH, the terminal device determines which report to send on the first uplink channel based on the first PUCCH. In this case, the first PUCCH is associated with the first uplink channel. As mentioned above, the first PUCCH is also associated with a report. The report sent by the terminal device on the first uplink channel is the report associated with the first PUCCH. As shown in Figure 11, the report sent by the terminal device on the first uplink channel is report x. As shown in Figure 12, the report sent by the terminal device on the first uplink channel is report y.

[0122] For example, when a terminal device needs to select one report to send between report x and report y, the terminal device makes the selection based on the DCI. For instance, the DCI may explicitly or implicitly indicate which report the terminal device should choose. For example, the PUCCH sent by the terminal device includes multiple bits, which, in addition to carrying information requesting resources, may also carry information to determine the report payload size (i.e., the number of bits sent on the uplink channel). The network device can allocate uplink channel resources of appropriate size to the report based on the payload size information in the PUCCH. Since the payload sizes of reports x and y may be different, the network device indicates in the DCI which report the uplink channel is used to send. For example, if report x uses a first SR configuration and report y uses a second SR configuration, the network device indicates in the DCI which report the uplink channel is used to send.

[0123] For example, when a terminal device needs to select one report to send between report x and report y, the terminal device makes the selection based on the DCI, the first PUCCH, and the second PUCCH. If the terminal device determines that the DCI is associated with the first PUCCH based on the DCI, it selects the report associated with the first PUCCH; otherwise, if the terminal device determines that the DCI is associated with the second PUCCH based on the DCI, it selects the report associated with the second PUCCH. This application embodiment does not limit how the DCI is associated with which sent PUCCH. For example, the DCI indicates which PUCCH it is associated with.

[0124] In some embodiments, the terminal device determines the report associated with the first PUCCH in the first report and the second report prior to the first PUCCH based on at least one of the following: the priority of the first report and the second report; the chronological order of the first report and the second report.

[0125] For example, as shown in Figure 9, the terminal device sends the first PUCCH at PUCCH transmission time k. Since report x is earlier than report y in time, it is assumed that the first PUCCH is associated with report x. Based on the principle of first-come, first-served, it initiates a resource request for report x first.

[0126] For example, as shown in Figure 10, although report x is earlier than report y in time, report y has a higher priority. Therefore, the first PUCCH is considered to be associated with report y, and a resource request is initiated for report y first, that is, the report with higher priority is served first.

[0127] In some embodiments, the terminal device determines a first timer for a report associated with the first PUCCH; and / or, the terminal device determines a second timer for a report associated with the second PUCCH; and / or, the terminal device determines a first counter and a first maximum number of transmissions for a report associated with the first PUCCH; and / or, the terminal device determines a second counter and a second maximum number of transmissions for a report associated with the second PUCCH.

[0128] Figure 13 is another example diagram of multiple uplink reports according to an embodiment of this application. Based on Figure 9, the first timer and the second timer are schematically illustrated, and the similarities to Figure 9 will not be repeated. The terminal device sends a first PUCCH and a second PUCCH, and the terminal device determines a timer for each report associated with a PUCCH. After a report meets the triggering condition, the terminal device should avoid sending resource requests (PUCCHs) for the same report multiple times. For example, if the terminal device sends a first PUCCH for report x at PUCCH transmission time k, then a period of waiting for the network device to respond should be allowed. It is unnecessary to continuously send PUCCHs for report x at PUCCH transmission times k+1 and k+2, as this would waste power unnecessarily and cause additional interference to other devices. Therefore, when sending the first PUCCH, the terminal device can start a first timer (timer x). During the timer's operation, it is not allowed to send PUCCHs for report x again; that is, the terminal device will not send PUCCHs for report x at PUCCH transmission times k+1 and k+2. In other words, when the first timer is running, the terminal device does not send a PUCCH for the report associated with the first PUCCH.

[0129] However, the terminal device can send PUCCHs for reports other than report x on PUCCH transmission times k+1 and k+2. For example, the terminal device can send a PUCCH (second PUCCH) for report y on PUCCH transmission time k+1. In other words, report y is not affected by timer x, but is controlled by timer y (second timer). Timer y is used in the same way as timer x. In other words, when the second timer is running, the terminal device does not send PUCCHs for reports associated with the second PUCCH. By using independent timers for different reports, resource requests can be initiated more promptly. Otherwise, if report x and report y share timer x, the terminal device cannot initiate a resource request for report y on PUCCH transmission times k+1 and k+2, but can only initiate a resource request for report y on PUCCH transmission time k+3 (when timer x has stopped), which introduces unnecessary delays for the transmission of report y. Similarly, the use of timers can be extended to the situation in Figure 10. The terminal device sends a PUCCH for report y at PUCCH transmission time k and uses timer y for report y. The terminal device sends a PUCCH for report x at PUCCH transmission time k+1 and uses timer x for report x.

[0130] For example, as shown in Figure 13, a terminal device sends a PUCCH, but the PUCCH may not be successfully received by the network device. For instance, the network device may not receive the PUCCH sent by the terminal device at PUCCH transmission time k. The network device sends a DCI not because it received the PUCCH at PUCCH transmission time k, but because it received the PUCCH at PUCCH transmission time k+1. Therefore, the terminal device can use a counter to record the number of PUCCH transmissions and retransmit the PUCCH if the maximum number of transmissions has not been reached. Different reports use independent counters to record the number of PUCCH transmissions for each report. Different reports can use independent maximum transmission counts, or they can use the same maximum transmission count. For example, when a report meets a trigger condition, the counter used by that report is set to 0.

[0131] For example, if the PUCCH transmission reaches the maximum number of transmissions, the terminal device will perform a random access procedure, which means that the PUCCH cannot be reliably transmitted and the terminal device needs to re-establish the uplink connection.

[0132] In some embodiments, the terminal device sends the first PUCCH at a first transmission occasion and sends the second PUCCH at a second transmission occasion; wherein the first transmission occasion and the second transmission occasion are provided by the same RRC configuration, or the first transmission occasion and the second transmission occasion are provided by two different RRC configurations.

[0133] For example, some transmission occasions are used to send PUCCH (including initial and retransmission of PUCCH) for report x, and some transmission occasions are used to send PUCCH (including initial and retransmission of PUCCH) for report y. The transmission occasions available for report x and report y can be provided by the same RRC configuration. For example, report x and report y share multiple SR occasions provided by the same SR configuration (Scheduling Request configuration). When a report meets the triggering conditions, it can be sent on the most recent SR occasion (SR is also a type of PUCCH). Alternatively, the transmission occasions available for report x and report y can be provided by two RRC configurations. For example, report x uses a first SR configuration, and report y uses a second SR configuration; that is, different reports use independent SR configurations. An SR configuration is also an RRC configuration, therefore an RRC configuration can also be replaced with an SR configuration.

[0134] For example, report x and report y share the same SR configuration, but report x and report y use independent timers.

[0135] For example, report x and report y share the same SR configuration, but report x and report y use independent counters and / or independent maximum transmission counts.

[0136] For example, when report x and report y share the same SR configuration, the terminal device selects one of report x and report y to send on the uplink channel, and / or determines the report associated with the PUCCH to be sent at the PUCCH transmission time.

[0137] For example, if report x uses the first SR configuration and report y uses the second SR configuration, the network device can determine which report the terminal device needs to send by receiving the PUCCH at the time of transmission belonging to which SR configuration. If the network device receives the PUCCH at the time of transmission belonging to both SR configurations, it is assumed that the terminal device needs to send two reports. For example, the network device can instruct the terminal device in the DCI which report to send.

[0138] In some embodiments, if the first timer does not run during the first transmission timing and / or the first counter is less than the first maximum number of transmissions, the terminal device sends the first PUCCH during the first transmission timing and starts the first timer; and / or

[0139] If the second timer does not run during the second transmission opportunity and / or the second counter is less than the second maximum number of transmissions, the terminal device sends the second PUCCH during the second transmission opportunity and starts the second timer; and / or

[0140] If the first timer does not run during the first transmission opportunity and / or the first counter is less than the first maximum number of transmissions, the terminal device sends the first PUCCH during the first transmission opportunity and increments the first counter by one; and / or

[0141] If the second timer does not run during the second transmission opportunity and / or the second counter is less than the second maximum number of transmissions, the terminal device sends the second PUCCH during the second transmission opportunity and increments the second counter by one.

[0142] For example, as shown in Figure 13, reports x and y use timer x and timer y respectively. Report x uses counter x and maximum transmission count x, and report y uses counter y and maximum transmission count y. The PUCCH transmission timing k is associated with report x. If timer x does not run at PUCCH transmission timing k and the value of counter x is less than the maximum transmission count x, then the terminal device sends a first PUCCH at PUCCH transmission timing k, initiates a resource request for report x, starts timer x, and increments the value of counter x. The PUCCH transmission timing k+1 is associated with report y. If timer y does not run at PUCCH transmission timing k+1 and the value of counter y is less than the maximum transmission count y, then the terminal device sends a second PUCCH at PUCCH transmission timing k+1, initiates a resource request for report y, starts timer y, and increments the value of counter y.

[0143] In some embodiments, when the terminal device sends a report that meets the trigger condition on the first uplink channel, the terminal device cancels the report that meets the trigger condition, and / or resets or stops the timer determined for the report that meets the trigger condition.

[0144] For example, as shown in Figure 13, a terminal device sends a report that meets the triggering conditions on the uplink channel, namely report x or report y. The terminal device then cancels the report that meets the triggering conditions. Taking the terminal device sending report x as an example, "canceling the report that meets the triggering conditions" means that the terminal device will no longer send a PUCCH for report x at the PUCCH transmission time, that is, report x will no longer trigger PUCCH transmission. This is because the network device sending the DCI indicating the uplink channel has already indicated that the network device knows that the terminal device has sent a report. Therefore, after the terminal device sends report x on the uplink channel, it does not need to send a PUCCH for report x again.

[0145] For example, as shown in Figure 13, a terminal device sends a report that meets a trigger condition on the uplink channel. Taking the terminal device sending report x as an example, the terminal device resets or stops the timer x used by report x. This allows the terminal device to send a PUCCH for report x when the trigger condition is met again. Otherwise, if timer x continues to run, the terminal device cannot send a PUCCH for report x during the running of timer x. "Resetting" and "stopping" achieve different effects. Assuming timer x is set to x milliseconds, if timer x is reset, the remaining timer time is still x milliseconds. When report x meets the trigger condition again, the terminal device sends a PUCCH and starts timer x. The terminal device can only send a PUCCH retransmission after x milliseconds, meaning the frequency at which the terminal device sends a PUCCH for report x is fixed. If timer x is stopped, the remaining timer x is less than x milliseconds. When report x meets the trigger condition again, the terminal device sends a PUCCH and starts timer x again. The terminal device can send a PUCCH retransmission after less than x milliseconds, meaning the frequency at which the terminal device sends a PUCCH for report x gradually increases, allowing it to send PUCCH for report x more frequently.

[0146] For example, report x uses the first SR configuration, and report y uses the second SR configuration. If the terminal device sends a report that meets the trigger condition on the first uplink channel, the terminal device cancels the report that meets the trigger condition, and / or resets the timer determined for the report that meets the trigger condition.

[0147] For example, if report x and report y share the same SR configuration, and the terminal device sends a report that meets the trigger condition on the first uplink channel, the terminal device cancels the report that meets the trigger condition, and / or resets the timer determined by the report that meets the trigger condition.

[0148] In some embodiments, when the terminal device determines the first uplink channel based on the first PUCCH, the terminal device sends a report on the first uplink channel that meets the triggering conditions; upon receiving a response message or upon receiving a positive feedback message, the terminal device cancels the report that meets the triggering conditions, and / or resets or stops the timer determined for the report that meets the triggering conditions.

[0149] For example, as shown in Figure 11, the terminal device determines the first uplink channel based on the first PUCCH. Taking sending report x as an example, after report x meets the first triggering condition, the terminal device sends the first PUCCH at PUCCH transmission time k and sends report x on the uplink channel associated with the first PUCCH. If the network device fails to receive the first PUCCH, the network device will not receive report x on the uplink channel. If the terminal device cancels report x after sending it, even though the network device has not received report x, the terminal device will not retransmit the PUCCH for report x, thus losing the opportunity to retransmit report x.

[0150] To support PUCCH retransmission, the terminal device does not immediately cancel report x after sending it. Instead, it receives a response from the network device. If the terminal device receives a response, it cancels report x; otherwise, it does not cancel report x, thus allowing it to still retransmit PUCCH for report x, meaning report x can still trigger PUCCH transmission. Similarly, if the terminal device receives a response from the network device, it resets or stops timer x; otherwise, it does not reset or stop timer x. The terminal device's behavior depends on whether a response is received. Likewise, the terminal device's behavior can also depend on whether the received feedback is positive or negative, which will not be elaborated further.

[0151] In some embodiments, when the terminal device determines the first uplink channel based on the first PUCCH, the terminal device sends a report that the triggering condition is met on the first uplink channel; the terminal device receives a second DCI and sends the report that the triggering condition is met on a second uplink channel indicated by the second DCI.

[0152] For example, as shown in Figure 11, the terminal device determines the first uplink channel (case B) based on the first PUCCH. This means that, unlike case A, it does not need to send a report that meets the triggering conditions on the uplink channel (first uplink channel) according to the instruction of the DCI (first DCI). Taking sending report x as an example, after the terminal device sends report x on the uplink channel, if it receives a DCI (second DCI), it can resend report x on the second uplink channel indicated by the second DCI. That is, the terminal device is instructed by the network device to retransmit report x.

[0153] Although the terminal device does not need to receive the first DCI before the first uplink channel as in case A, it can receive the second DCI after the first uplink channel and send retransmissions of reports that meet the triggering conditions on the second uplink channel indicated by the second DCI. That is, the network device can schedule the retransmission of reports through the second DCI. For example, the second DCI can use the same format as the first DCI.

[0154] For example, as shown in Figure 11, after the terminal device sends report x on the first uplink channel, if it receives a positive feedback message, it cancels report x. If it receives a second DCI, it sends report x again on the second uplink channel indicated by the second DCI.

[0155] In some embodiments, if the terminal device determines that the second report meets the second triggering condition, and the terminal device determines that it has an available uplink channel, then the terminal device sends the second report on the uplink channel.

[0156] For example, when the second report meets the second triggering condition, if the terminal device finds an available uplink channel, it can choose not to send a second PUCCH but instead send the second report directly on the uplink channel. That is, the terminal device does not need to send a PUCCH for every triggered report. The available uplink channel may be obtained because the first report meets the first triggering condition, but if the second report meets the second triggering condition before the uplink channel is established, the terminal device sends the second report directly on the uplink channel without sending the first report; in other words, the second report preempts the first report, which is sent first. Since the first report has not yet been sent, the terminal device will not cancel the first report and will still send the first PUCCH for the first report later, meaning there is still an opportunity to send the first report later. For example, the above applies when the first and second reports share the same SR configuration.

[0157] In some embodiments, the second report has a higher priority than the first report.

[0158] For example, a second report is allowed to preempt the first report from being sent first only if the second report has a higher priority than the first report.

[0159] In some embodiments, when the terminal device determines the first uplink channel based on the first PUCCH, if the terminal device sends the first PUCCH no later than the time it determines that the second report satisfies the second triggering condition, then the terminal device determines that it already has an available uplink channel; or...

[0160] If the terminal device determines the first uplink channel based on the first DCI, and the terminal device receives the first DCI no later than the moment it determines that the second report satisfies the second triggering condition, then the terminal device determines that it already has an available uplink channel.

[0161] Figure 14 is another example diagram of multiple uplink reports according to an embodiment of this application. For example, as shown in Figure 14, the terminal device determines a first uplink channel (case B) based on a first PUCCH. Report x meets a first triggering condition, and the terminal device sends a first PUCCH for report x at PUCCH transmission time k. When report y (second report) meets a second triggering condition, the terminal device considers that there is already an available uplink channel. This uplink channel is the uplink channel associated with the first PUCCH. This is because the terminal device has already sent the first PUCCH before report y becomes a report that meets the triggering condition, and the uplink channel associated with the first PUCCH is the available uplink channel. Therefore, the terminal device sends report y on the uplink channel associated with the first PUCCH.

[0162] For example, as shown in Figure 8, the terminal device determines the first uplink channel based on the first DCI (case A). Report x meets the first triggering condition. The terminal device sends the first PUCCH for report x at the PUCCH transmission timing k. When report y (second report) meets the second triggering condition, the terminal device has already received the DCI indicating the uplink channel. Therefore, it believes that there is an available uplink channel. Thus, the terminal device sends report y on the uplink channel indicated by the DCI.

[0163] In some embodiments, the terminal device transmits an aperiodic CSI report or an aperiodic LTM CSI report or a third report that meets the triggering conditions on the third uplink channel;

[0164] Wherein, when the terminal device is configured with an uplink carrier, the first uplink channel and the third uplink channel occupy a first symbol set and a second symbol set that do not overlap in the time domain, respectively.

[0165] For example, a terminal device sends a report r (the triggered first report or the triggered second report) that meets the triggering conditions on an uplink channel r (the first uplink channel) indicated by DCI r (the first DCI) or associated with PUCCH r (the first PUCCH). The terminal device also sends a traditional aperiodic CSI report or a traditional aperiodic LTM CSI report (the third report) on an uplink channel s (the third uplink channel) indicated by DCI s (the third DCI). Alternatively, it sends a report s (the third report) that meets the triggering conditions on an uplink channel s (the third uplink channel) indicated by DCI s (the third DCI) or associated with PUCCH s (the third PUCCH). Uplink channels r and s do not overlap in the time domain, meaning reports r and s do not overlap in the time domain. This also applies to the case where report r is always the event-triggered first report, for example, when there is no second report. In this case, reports r and s also do not overlap in the time domain.

[0166] For example, a terminal device does not expect two reports scheduled by two DCIs to overlap in the time domain, where one report is an event-triggered report r and the other is an event-triggered report s; or, one report is an event-triggered report r and the other is a traditional aperiodic CSI report s; or, one report is an event-triggered report r and the other is a traditional aperiodic LTM CSI report s. This is equivalent to: for a terminal device, only one of the following exists at a given transmission time: an aperiodic CSI report, an aperiodic LTM CSI report, and a report that meets the triggering conditions. The above also applies to the case where report r is always the first event-triggered report, for example, when there is no second report. In this case, reports r and s also do not overlap in the time domain.

[0167] In some embodiments, the terminal device transmits at least one of an aperiodic CSI report, a semi-persistent CSI report, or a periodic CSI report on the fourth uplink channel; wherein, when the first uplink channel and the fourth uplink channel overlap in the time domain, the terminal device transmits a report that meets the triggering condition on the first uplink channel; or...

[0168] The terminal device transmits at least one of an aperiodic LTM CSI report, a semi-persistent LTM CSI report, or a periodic LTM CSI report on the fourth uplink channel; wherein, when the first uplink channel and the fourth uplink channel overlap in the time domain, the terminal device transmits at least one of an aperiodic LTM CSI report, a semi-persistent LTM CSI report, or a periodic LTM CSI report on the fourth uplink channel.

[0169] For example, a terminal device sends a report r (the triggered first report or the triggered second report) that meets the triggering conditions on an uplink channel r (the first uplink channel) indicated by DCI r (the first DCI) or associated with PUCCH r (the first PUCCH). The terminal device also needs to simultaneously send a traditional CSI report h on an uplink channel h (the fourth uplink channel). Traditional CSI reports include aperiodic CSI reports sent on PUSCH, semi-persistent CSI reports sent on PUSCH or PUCCH, or periodic CSI reports sent on PUCCH. In this case, the terminal device only sends report r and not the traditional CSI report h; that is, the event-triggered report takes precedence over the traditional CSI report. Here, "sending a traditional CSI report" means that the information sent only includes traditional CSI reports (which may also include multiple traditional CSI reports multiplexed together), but not traditional LTM CSI reports. For example, the above terminal device behavior occurs when the terminal device is configured with an uplink carrier. The above also applies to the case where report r is always the event-triggered first report, for example, when there is no second report. In this scenario, the terminal device only sends report r and does not send the traditional CSI report h.

[0170] For example, if a terminal device sends a report r that meets the triggering conditions on the uplink channel r indicated by DCI r or associated with PUCCH r, the terminal device also needs to simultaneously send a traditional LTM CSI report h on the uplink channel h. The traditional LTM CSI report includes an aperiodic LTM CSI report sent on PUSCH, a semi-persistent LTM CSI report sent on PUSCH or PUCCH, or a periodic LTM CSI report sent on PUCCH. In this case, the terminal device only sends the traditional LTM CSI report h and not the report r; that is, the traditional LTM CSI report takes precedence over the event-triggered report. Here, "sending a traditional LTM CSI report" means that the information sent includes a traditional LTM CSI report (which may also include multiple traditional LTM CSI reports multiplexed together). Optionally, the information sent may also include a traditional CSI report (which may also include multiple traditional CSI reports multiplexed together). For example, traditional LTM CSI reports and traditional CSI reports can be multiplexed together for transmission, so the information sent includes both traditional LTM CSI reports and traditional CSI reports. For example, the above-described terminal device behavior occurs when the terminal device is configured with an uplink carrier. This also applies to the case where report r is always the first report triggered by the event, for example, when there is no second report. In this case, the terminal device only sends the traditional LTM CSI report h and does not send report r.

[0171] The above embodiments are merely illustrative examples of the embodiments of this application, but this application is not limited thereto, and appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined. The embodiments of this application are illustrated using two reports as an example, but can be extended to cases with more than two reports, which will not be elaborated further.

[0172] Through the embodiments of this application, when a terminal device has multiple event-triggered reports to send, the terminal device selects one event-triggered report to send. When the terminal device has both an event-triggered report and a network scheduling report to send, the terminal device selects one report to send. This avoids ambiguity between the terminal device and the network device regarding which reports are actually sent, thereby achieving timely and reliable report transmission.

[0173] Second aspect of the embodiments

[0174] This application provides a method for sending an uplink report, described from the perspective of a terminal device. Descriptions identical to those in the first aspect of the embodiment are omitted. Figure 15 is a schematic diagram of the uplink report sending method according to an embodiment of this application. As shown in Figure 15, the method includes:

[0175] 1501, The terminal device determines that the first report meets the first triggering condition;

[0176] 1502, the terminal device sends the first PUCCH;

[0177] 1503, the terminal device determines a first uplink channel based on the received first DCI, wherein the first uplink channel is indicated by the first DCI; or, the terminal device determines a first uplink channel based on the first PUCCH, wherein the first uplink channel is associated with the first PUCCH;

[0178] 1504, before the terminal device sends the first uplink channel, if it is determined that the second report meets the second triggering condition, the terminal device sends the first report and the second report on the first uplink channel.

[0179] It is worth noting that Figure 15 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 15 above.

[0180] Figure 16 is another example diagram of multiple uplink reports according to an embodiment of this application. For example, as with Figure 5, Figure 16 assumes two reports (report x and report y) to be sent before the uplink channel. The terminal device can select one of reports x and report y to send on the uplink channel according to Figure 5, or the terminal device can send both reports x and report y on the uplink channel according to Figure 16, i.e., one uplink channel carries two reports. In other words, the actions of the terminal device include: sending report x, or sending report y, or sending both reports x and report y.

[0181] The difference between Figure 16 and Figure 5 is that the terminal device has an additional option: it can send report x and report y on a single uplink channel. When the terminal device selects to send either report x or report y, the previously described embodiments also apply and will not be repeated. The following description only addresses the behavior when the terminal device selects to send both report x and report y. This application uses two reports as an example for illustration, but it can be extended to cases with more than two reports, which will not be elaborated upon further.

[0182] In some embodiments, the terminal device transmits the first report and the second report on the first uplink channel when the following condition is met: the terminal device determines the first report and the second report as reports associated with the first PUCCH, wherein the first report and the second report are earlier than the first PUCCH.

[0183] For example, under certain conditions, the terminal device transmits the first report and the second report on a single uplink channel, as shown in Figure 16. Reports x and y satisfy the first and second triggering conditions, respectively. The terminal device transmits a PUCCH (the first PUCCH) only once at PUCCH transmission time k, instead of sending a PUCCH for each report. This is because the terminal device can receive the DCI in response to the first PUCCH, simultaneously transmitting reports x and y on the uplink channel indicated by the DCI (the first uplink channel). Therefore, the terminal device does not need to send a second PUCCH for report y, but only needs to send a PUCCH once for both reports. The terminal device identifies the first report and the second report as reports associated with the first PUCCH.

[0184] In some embodiments, the terminal device transmits first information on the first uplink channel or the first PUCCH, wherein the first information includes the number of reports transmitted on the first uplink channel.

[0185] For example, the terminal device can autonomously determine whether to send one or two reports. To avoid ambiguity between the network device and the terminal device regarding the number of reports sent, the terminal device notifies the network device of the number of reports sent (the first information). As shown in Figure 16, the terminal device can send the first information on the first uplink channel, meaning the sent report includes the first information; or, the terminal device can send the first information on the first PUCCH, meaning the first PUCCH includes multiple bits, thereby enabling it to carry and indicate the first information.

[0186] In some embodiments, the terminal device transmits payload size information in the first part of the first uplink channel (CSI part 1), and transmits the first information, the second information, and the third information in the second part of the first uplink channel (CSI part 2); or,

[0187] The terminal device transmits payload size information on the first PUCCH and transmits the first information, the second information, and the third information on the first uplink channel; or...

[0188] The terminal device transmits the first information on the first PUCCH, transmits the second information in the first part CSI (CSI part 1) of the first uplink channel, and transmits the third information in the second part CSI (CSI part 2) of the first uplink channel;

[0189] The second information includes the report ID information and / or the number of reports (quantity) of each sent report; the third information includes the report quantity information of each sent report; and the payload size information includes the total number of bits of the first information, the second information, and the third information.

[0190] Figure 17 is an example diagram of the information in an embodiment of this application. For example, as shown in Figure 17, the content (i.e., the reporting content) of one or two reports sent by the terminal device on the uplink channel includes first information, second information, and third information. The first information includes the number of reports; the second information includes the report ID of each report, which can also be replaced by an event ID or a report configuration ID. A report ID identifies a report configuration. The network device can know which report the terminal device sent based on the report ID, and also know all the configuration information of that report. For example, the configuration information includes a set of measurement reference signals. Since the reference signal index is an index of the reference signals in the set of measurement reference signals, the network device can know the bit width of the reference signal index based on the report configuration, i.e., the bit width of the reference signal index depends on the report ID; the second information includes the report ID of each report. The second information also includes the number of reports for each report. For example, the number of reports includes L1-RSRP and reference signal index. For each reported reference signal index, a corresponding L1-RSRP measurement result is reported. Since the number of reference signals that meet the triggering conditions is variable, the terminal device can independently determine how many reports to report, i.e. how many beams to report, when only reporting reference signals that meet the triggering conditions. This makes the number of bits in each report variable. Therefore, the number of reports needs to be notified to the network device. The third information includes the number of reports for each report, i.e., the reference signal index and L1-RSRP of each report.

[0191] Figure 18 is another example diagram of the information in an embodiment of this application. For example, the difference between Figure 18 and Figure 17 is that the second information does not include the number of reports for each report. The number of reports is not determined autonomously by the terminal device, but configured by the network device and included in the report configuration. For example, if the network device configures the terminal device to send N reports, then the terminal device always sends N reports (not just reporting reference signals that meet the triggering conditions). Some of the reports that do not meet the triggering conditions can simply be padding bits, so that the number of bits in each report is fixed.

[0192] For both Figure 17 and Figure 18, the number of reports, report ID, number of reports, and the bit width of L1-RSRP are fixed or known to both the network device and the terminal device. The bit width of the reference signal index depends on the report ID, the number of bits for the second information depends on the first information, and the number of bits for the third information depends on the first and second information. Therefore, the network device can only obtain the second information after obtaining the first information, and the third information can only be obtained after obtaining the first and second information. To enable the network device to obtain the first, second, and third information sequentially, the format of the reported content can be determined as follows.

[0193] Method 1: The terminal device transmits payload size information in CSI part 1 on the first uplink channel, and transmits first, second, and third information in CSI part 2 on the first uplink channel. The payload size represents the total number of bits in the first, second, and third information. After the network device decodes the payload size information (whose bit width is fixed), it can decode the bits of the first, second, and third information, and then correctly interpret the bits of each part according to the bit mapping order in Figure 17 or Figure 18. The definition of the first uplink channel is the same as before.

[0194] Method 2: The terminal device sends payload size information on the first PUCCH and sends first, second, and third information on the first uplink channel. The network device obtains the payload size based on the first PUCCH and then correctly interprets the bits received on the first uplink channel according to the bit mapping order in Figure 17 or Figure 18. The definition of the first PUCCH is the same as before.

[0195] Method 3: The terminal device sends the first information on the first PUCCH, the second information in CSI part 1 on the first uplink channel, and the third information in CSI part 2 on the first uplink channel. The network device obtains the first information based on the first PUCCH, and from the first information, it can know the number of bits of the second information (CSI part 1). Therefore, it interprets the second information according to the bit mapping order in Figure 17 or Figure 18. Then, based on the first and second information, it can know the number of bits of the third information (CSI part 2), and thus interpret the third information according to the bit mapping order in Figure 17 or Figure 18.

[0196] In some embodiments, if the terminal device determines a report in the first report and the second report, and transmits the determined report on the first uplink channel, the terminal device transmits the determined report and padding bit information on the first uplink channel.

[0197] For example, the terminal device always determines the number of bits Q to be transmitted on the uplink channel according to the maximum number of reports. When only a portion of the reports are transmitted, some bits in Q can simply be padding bits, which makes the value of Q always fixed. For example, the Q bits can be determined according to the bit mapping order in Figure 17 or Figure 18, assuming that the number of reports equals the maximum number of reports. When a report is not transmitted, padding bits are used as placeholders, and the network device can correctly interpret the information corresponding to each part of the bits according to this mapping order.

[0198] In some embodiments, if the terminal device determines that the first report and the second report are reports associated with the first PUCCH, the terminal device determines a third timer for the report associated with the first PUCCH; and / or, the terminal device determines a third counter and a third maximum number of transmissions for the report associated with the first PUCCH.

[0199] For example, as shown in Figure 16, the terminal device sends a PUCCH (first PUCCH) only once for reports x and y. That is, the reports associated with the first PUCCH include reports x and y. The terminal device determines a third timer for the reports associated with the first PUCCH. The third timer is used in the same way as the first and second timers.

[0200] For example, as shown in Figure 16, the reports associated with the first PUCCH include report x and report y. The terminal device determines a third counter and a third maximum number of transmissions for the reports associated with the first PUCCH. The third counter and the third maximum number of transmissions are used in the same way as the first counter (or second counter) and the first maximum number of transmissions (or second maximum number of transmissions).

[0201] In some embodiments, the terminal device determines the third timer for the report associated with the first PUCCH based on a first timer associated with the first report and a second timer associated with the second report; and / or,

[0202] The terminal device determines the third counter for the report associated with the first PUCCH based on the first counter associated with the first report and the second counter associated with the second report; and / or

[0203] The terminal device determines the third maximum number of transmissions for the report associated with the first PUCCH based on the first maximum number of transmissions associated with the first report and the second maximum number of transmissions associated with the second report.

[0204] For example, the terminal device determines a third timer for reports (report x and report y) associated with the first PUCCH. Since report x and report y are associated with timer x (first timer) and timer y (second timer) respectively, the value of the third timer can be the maximum value of the first timer value and the second timer value, or the minimum value of the first timer value and the second timer value.

[0205] For example, the terminal device determines a third counter and a third maximum transmission count for reports (report x and report y) associated with the first PUCCH. The value of the third counter can be the maximum value of the first counter and the second counter, or the minimum value of the first counter and the second counter. The value of the third maximum transmission count can be the maximum value of the first maximum transmission count and the second maximum transmission count, or the minimum value of the first maximum transmission count and the second maximum transmission count.

[0206] The above embodiments are merely illustrative examples of embodiments of this application, but this application is not limited thereto, and appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0207] Through the embodiments of this application, when a terminal device has multiple event-triggered reports to send, the terminal device selects one or more event-triggered reports to send. This avoids ambiguity between the terminal device and network device regarding which reports are actually sent, thereby achieving timely and reliable report transmission.

[0208] Third aspect of the embodiments

[0209] This application provides a method for receiving uplink reports, described from the perspective of a network device. The embodiments of the third aspect can be combined with the embodiments of the first and second aspects, and the content identical to that in the embodiments of the first and second aspects will not be repeated.

[0211] 1901, the network device receives a first PUCCH sent by the terminal device; wherein the terminal device determines that the first report meets the first triggering condition;

[0212] 1902, the network device determines a first uplink channel, wherein the first uplink channel is determined according to a first DCI, and the first uplink channel is indicated by the first DCI; or, the first uplink channel is determined according to a first PUCCH, and the first uplink channel is associated with the first PUCCH;

[0213] 1903, the network device receives a report on the first uplink channel; wherein, before the terminal device sends the report on the first uplink channel, if it is determined that the second report meets the second triggering condition, the terminal device determines one report from the first report and the second report, and sends the determined report on the first uplink channel, or the terminal device sends the first report and the second report on the first uplink channel.

[0214] It is worth noting that Figure 19 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 19 above.

[0215] In some embodiments, the network device may send the first DCI to the terminal device and determine the first uplink channel based on the first DCI. In other embodiments, the network device may determine the first uplink channel based on the association between the first PUCCH and the first uplink channel.

[0216] In some embodiments, the network device may also send configuration information to the terminal device to configure the terminal device to perform event-triggered reporting. For example, the first triggering condition and / or the second triggering condition can be configured by the network device, and this application is not limited thereto; for example, they can also be predefined or defaulted.

[0217] The above embodiments are merely illustrative examples of embodiments of this application, but this application is not limited thereto, and appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0218] Through the embodiments of this application, when a terminal device has multiple event-triggered reports to send, the terminal device selects one or more event-triggered reports to send. When the terminal device has both event-triggered reports and network scheduling reports to send, the terminal device selects one or more reports to send. This avoids ambiguity between the terminal device and the network device regarding which reports are actually sent, thereby achieving timely and reliable report transmission.

[0219] Fourth aspect of the embodiment

[0220] This application provides an uplink report sending device. This device may be, for example, a terminal device, or one or more components or parts configured within the terminal device; details identical to those in the first and second aspects will not be repeated.

[0221] Figure 20 is a schematic diagram of an uplink report sending apparatus according to an embodiment of this application. As shown in Figure 20, the uplink report sending apparatus 2000 includes a processing unit 2001 and a sending unit 2002.

[0255] In some embodiments, the transmitting unit 2002 transmits an aperiodic CSI report or an aperiodic LTM CSI report or a third report that meets the triggering conditions on the third uplink channel;
