[0001] This application relates to, but is not limited to, the field of communications, and particularly to a data transmission method, terminal equipment, network equipment, computer-readable storage medium, and computer program product. Background Technology

[0002] Currently, for the UE-initiated beam management process when the user equipment (UE) is operating in a carrier aggregation (CA) scenario, the relevant technology uses one bit of the first physical uplink control channel (PUCCH) to indicate to the second physical uplink shared channel (PUSCH) that there is at least one event of at least one component carrier (CC) to trigger the UE to initiate beam reporting (UEIBR).

[0003] However, if the relevant network or device cannot determine exactly how many events were triggered on how many CCs, then the relevant network or device will allocate resources to the second PUSCH based on the maximum payload size. That is, the allocated resources must be able to carry the payload required when all events on all CCs are triggered simultaneously, thus resulting in resource waste. Summary of the Invention

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0039] Before explaining this application, the following explanation is given regarding UE-initiated beam reporting in related technologies:

[0040] Channel State Information (CSI) Reporting: The CSI feedback reporting framework is a crucial component of 5G NR, allowing the UE to report channel state information to the gNB for effective beam management and resource scheduling. Beam management refers to beamforming technology, which adjusts the amplitude and phase of the antenna to concentrate signal energy into a narrow beam in a specific direction, thereby enhancing coverage and reducing interference. The beam management process mainly includes: First, scanning, where the gNB transmits multiple beams in different spatial directions, and the UE listens to / scans these beams in different receiving spaces. The UE evaluates the received signal quality of each beam, including metrics such as Reference Signal Receiving Power (RSRP) and Signal-to-Interference-plus-Noise Ratio (SINR); then, the UE reports the beam quality and decision information to the gNB. The network can then adjust the current beam based on the beam measurement results reported by the UE.

[0041] It should be noted that the CSI feedback process consists of two main steps: first, CSI resource configuration, where the gNB configures the UE to send a Channel State Information Reference Signal (CSI-RS) and / or a Synchronization Signal / Physical Broadcast Channel block (SS / PBCH block / SSB); second, CSI report configuration, where the UE measures the CSI-RS and / or SSB, and then reports the CSI to the gNB according to the configuration.

[0042] In traditional beam management procedures, existing standards primarily focus on L1 layer beam measurement and reporting configured by the gNB. Specifically, the gNB can configure or activate periodic or semi-persistent (P / SP) beam reporting, for example, reporting N optimal beams and their corresponding L1 RSRP values. Furthermore, the gNB can also trigger aperiodic (AP) beam reporting to quickly acquire the optimal beam for data or control channel transmission. However, such frequent beam reporting configuration undoubtedly increases the uplink reporting burden and control signaling overhead. If the beam reporting configuration or triggering frequency is low, the UE's beam reports may become outdated, and the gNB may not be able to continuously obtain the optimal beam, leading to a significant degradation in performance and coverage, as well as increased beam measurement reporting latency.

[0043] Considering the significant overhead and latency of traditional CSI measurement and reporting configuration frameworks, this paper proposes to further enhance the UE-initiated / event-driven beam management process to reduce beam management overhead and / or latency. By enhancing the UE-initiated / event-driven beam management approach, if the UE has a better and more timely understanding of beam quality changes, the UE-initiated beam reporting process will obtain more timely beam reports while reducing reporting overhead. If the UE determines, for example, that the current beam quality has deteriorated, the UE can trigger a beam report without requiring network configuration or frequent reporting.

[0044] Based on the discussion of User Equipment (UE)-initiated beam management in 3rd Generation Partnership Project (3GPP) Release 19 (R19), the Radio Access Network (RAN) 1#116bis meeting agreed to implement UE-initiated beam reporting (UEIBR) through the following modes based on uplink control information (UCI): Mode A (gNB dynamically scheduling UCI) and Mode B (UCI in pre-configured resource(s) for second UL channel).

[0045] Here, during the beam report transmission procedure for UE-initiated / event-driven beamreporting, the following modes are supported:

[0046] Mode A:

[0047] Step 1: The UE sends a first PUCCH (one-bit / multi-bit) to request resources for a second UL channel to carry beam reports.

[0048] FFS: Request format, e.g., SR or a new UCI type.

[0049] Step 2: The UE detects the DCI format and indicates that resource UL channel 1 carries a beam report.

[0050] Step 3: Send a beam report in the second UL channel.

[0051] FFS: Details on the second UL channel, e.g., whether the second UL channel is PUCCH, PUSCH, or both.

[0052] Mode A represents a basic UE capability (i.e., all UEs supporting UE-initiated / event-driven beam reporting should support this feature).

[0053] Mode B:

[0054] Step 1: The UE transmits a first PUCCH (one-bit / multi-bit) notifying a second UL channel to carry beam report;

[0055] FFS: Notification format, e.g., SR or a new UCI type;

[0056] Step 2: The UE transmits the beam report in the second UL channel 1.

[0057] FFS: Details on the second UL channel, e.g., whether the second UL channel is PUCCH, PUSCH or both.

[0058] The notification in step 1 is in a separate reporting instance from the beamreport in step 2;

[0059] FFS: Whether the UE receives acknowledgment information with response to each step for all modes. For the above procedures, cross-CC beamreporting is supported in both modes.

[0060] It should be noted that, for UEs operating in CA scenarios, there may be situations where one or more CCs among multiple CCs simultaneously meet the first condition, triggering a report. Furthermore, current standardization discussions may aim to support a maximum of three events: the current serving beam quality is below a threshold; at least one new beam quality is above a threshold compared to the current serving beam quality; at least one new beam quality is above a threshold compared to the Mth best quality in the active TCI state. Therefore, it is possible for multiple CCs and multiple events to simultaneously meet the first condition, triggering a report.

[0061] Considering CCs operating in different frequency bands, high-frequency CCs will frequently meet the first condition; while low-frequency CCs are more stable, and not many CCs will simultaneously meet the first condition. Considering multiple CCs operating in similar frequency bands, multiple CCs will simultaneously meet the first condition. Furthermore, when multiple CCs are configured in a CC list, their indicated TCI states are identical, and any new beams meeting the first condition will also be identical. To address these two scenarios, related technologies use a bit from the first PUCCH to indicate to the second PUSCH that at least one event from at least one CC triggers the UE to initiate beam reporting (UE-initiated beam reporting, UEIBR).

[0062] Figure 2 This is a flowchart illustrating a data transmission method provided in an embodiment of this application, as shown below. Figure 2 As shown, this method is applied to Figure 1 In the communication system 100 shown, the method includes:

[0063] Step 201: On the transmission occasion of the first physical uplink control channel and / or the second physical uplink channel, the terminal device sends the first information.

[0064] The first information includes information corresponding to the first event in the component carrier, and the first event is used to trigger or instruct the terminal device to report.

[0065] In this application embodiment, the reporting timing may refer to the time slot in which the first PUCCH and / or the second physical uplink channel resources are to be transmitted (or located).

[0066] In this embodiment, the first event includes one or more of the following: the quality measurement of the current serving beam is less than a first threshold; the quality measurement of at least one new beam is higher than the quality measurement of the current serving beam and higher than a second threshold; the quality measurement of at least one new beam is higher than the Mth best quality measurement in the active TCI state and higher than a third threshold. Here, the first threshold, the second threshold, and the third threshold can be absolute thresholds; an absolute threshold refers to the minimum signal value required for normal communication between the terminal device and the network device.

[0067] In this embodiment of the application, beam quality is evaluated by one or more of RSRP, Reference Signal Receiving Quality (RSRQ), and SINR.

[0068] In this embodiment of the application, the information corresponding to the first event includes the CSI information corresponding to the first event, or the specific triggering condition content corresponding to the first event, or the beam information corresponding to the first event, or the CC information corresponding to the first event; that is, in this application, the terminal device reports the specific information of the event triggered on each CC at the reporting time of the first physical uplink control channel and / or the second physical uplink channel.

[0069] Here, CSI information includes the Channel State Indicator Reference Signal Resource Indicator (CSI-RSresource indicator, CRI) / Synchronization Data Block ID (SSB ID) corresponding to each event, and its corresponding Layer 1 (L1)-RSRP / L1-SINR.

[0070] Based on this, assume that each of the M CCs has at least one event triggered, where CC#m has N events. m If a number of events are triggered, then there are a total of An event is triggered, and the CSI information corresponding to each event is defined as the first information.

[0071] In this embodiment of the application, the second physical uplink channel includes the second PUCCH and the second PUSCH.

[0072] It should be noted that PUCCH (i.e., the first PUCCH or the second PUCCH) is used to carry UCI, meaning that UCI is sent on the PUCCH resource. PUSCH is used to carry data.

[0073] Here, UCI includes at least one of the following: Hybrid Automatic Repeat reQuest ACK (HARQ-ACK) information, channel state information (CSI), and scheduling request (SR) information.

[0074] It should be noted that in CA scenarios, PUCCH is transmitted on the primary component carrier (PCC) or primary cell (PCell). When the CA scenario is configured to transmit PUCCH on secondary component carriers (SCC) or secondary cells (SCell), the aggregated carriers can be divided into two PUCCH carrier groups. Each PUCCH carrier group has a designated carrier for PUCCH transmission. The carrier group containing the PCC (or PCell) is the primary PUCCH carrier group, and PUCCH is transmitted on the PCC (or PCell). The secondary PUCCH carrier groups all contain SCCs (or SCells). Higher-layer signaling configures one of the SCCs (or SCells) to transmit PUCCH, which is called PUCCHSCell. The HARQ-ACK of all downlink transmissions (including PDSCH and PDCCH requiring HARQ-ACK feedback) on all carriers in each carrier group is transmitted in the PUCCH on the designated carrier.

[0075] Step 202: The network device receives the first information.

[0076] It should be noted that the first message can be sent directly by the terminal device or by a third-party device connected to the terminal device.

[0077] This application provides a data transmission method, comprising: a terminal device sending first information at reporting times on a first physical uplink control channel and / or a second physical uplink channel; wherein the first information includes information corresponding to a first event in a component carrier, the first event being used to trigger or instruct the terminal device to report; and a network device receiving the first information. In other words, this application proposes a data transmission method in a cross-carrier scenario. By sending specific information corresponding to multiple events on multiple component carriers at multiple reporting times on the first physical uplink control channel and / or the second physical uplink channel, the network device can accurately understand the number of events triggered on each component carrier. Therefore, the network device can configure resources according to the actual number, solving the problem of resource waste in related technologies.

[0078] In this embodiment of the application, for the first information sent by the terminal device, the component carrier corresponding to the first information in each reporting time is different, and / or the first event supported or occurred by the component carrier corresponding to the first information in each reporting time is different.

[0079] For example, the first information in timing 1 includes information corresponding to event 1 and event 2 supported or transmitted by component carrier 1; the first information in timing 2 includes information corresponding to component carrier 2; and the first information in timing 3 includes information corresponding to event 3 supported or transmitted by component carrier 1.

[0080] In this embodiment of the application, for the first information sent by the terminal device, information corresponding to one or more first events is transmitted at each reporting time.

[0081] For example, the first information in timing 4 includes information corresponding to events 1 and 2 supported or transmitted by component carrier 1, or the first information in timing 5 includes information corresponding to component carrier 4.

[0082] In practical applications, the first physical uplink control channel and / or the second physical uplink channel may correspond to multiple reporting opportunities. Based on this, step 201, sending the first information during the reporting opportunities of the first PUCCH and / or the second physical uplink channel, can be achieved through the following steps:

[0083] At the Kth reporting opportunities of the first PUCCH and / or the second physical uplink channel, or at the Kth available reporting opportunities, send K sets of first information.

[0084] Where K is a positive integer.

[0085] It should be noted that if each of the M CCs has at least one event triggered, then among the M CCs, CC#m contains event#{i=1,…,N}. m When a PUCCH is triggered (m = 1, ..., M), these events are divided into K event groups; then the terminal can send the CSI information corresponding to these K event groups on K transmission occasions after the first PUCCH or on K available transmission occasions.

[0086] In this embodiment of the application, K groups of first information are information corresponding to one component carrier or one group of component carriers; each group of first information includes information corresponding to all triggered first events in one component carrier or one group of component carriers.

[0087] It should be noted that if each of the M CCs has at least one event triggered, the CSI information corresponding to one CC or one CC group is considered as one group of CSI information. Each group of CSI information contains the CSI information corresponding to all the triggered events in that CC or CC group, for a total of K groups. Then the terminal can send these K groups of corresponding CSI information on K transmission occasions or K available transmission occasions after the first PUCCH.

[0088] In the case of CC groups, M CCs can be divided into A CC groups. The grouping method can be configured in advance according to RRC. A is less than or equal to M, and each CC can only belong to one CC group. The CCs in each group do not overlap.

[0089] For example, in a CA scenario, the CA includes multiple CCs, namely CC1, CC2, CC3, CC4, CC5, and CC6. CC1 and CC2 are grouped into the same CC group, CC3 and CC4 into the same CC group, and CC5 and CC6 into the same CC group. During the three reporting opportunities of the first PUCCH and / or the second physical uplink channel, or during the three available reporting opportunities, information corresponding to all triggered events of the CCs in the three CC groups is reported three times. Specifically, the first report is for all triggered events corresponding to CC1 and CC2; the second report is for all triggered events corresponding to CC5 and CC6; and the third report is for all triggered events corresponding to CC3. (Here, why is there no report of relevant information for CC4? Because there are no corresponding triggered events in CC4.)

[0090] For example, in a CA scenario, the CA includes multiple CCs, namely CC1, CC2, CC3, CC4, CC5 and CC6; during the six reporting opportunities of the first PUCCH and / or the second physical uplink channel, or the six available reporting opportunities, information corresponding to all the triggered events in CC1, CC2, CC3, CC4, CC5 and CC6 are reported six times respectively.

[0091] In this embodiment of the application, K groups of first information are information corresponding to the same first event as a group, and the component carriers corresponding to each group of first information belong to the same component carrier or different component carriers.

[0092] It should be noted that if each of the M CCs has at least one event triggered, the CSI information corresponding to one type of event in the M CCs is considered as one group. The event type corresponding to each group of CSI information is the same, and the CC corresponding to each group of CSI information can belong to one CC or multiple CCs. Similarly, the terminal can send these K groups of corresponding CSI information on K transmission occasions after the first PUCCH or on K available transmission occasions.

[0093] For example, in a CA scenario, the CA includes multiple CCs, namely CC1, CC2, CC3, CC4, CC5, and CC6; CC1 supports or occurs events corresponding to the first type, CC2 supports or occurs events corresponding to the first type, CC3 supports or occurs events corresponding to the third type, CC4 supports or occurs events corresponding to the second type, CC5 supports or occurs events corresponding to the second type, and CC6 supports or occurs events corresponding to the third type. CC1 and CC2 are grouped into the same CC group, CC3 and CC6 are grouped into the same CC group, and CC4 and CC5 are grouped into the same CC group. Therefore, during the three reporting opportunities of the first PUCCH and / or the second physical uplink channel, or the three available reporting opportunities, the three... Report the information corresponding to the triggered events of the CCs in the three CC groups. The CCs corresponding to the first information in each group belong to the same CC or different CCs. For example, the first report reports the information corresponding to all the triggered events of CC3 and CC6 (the first report means that the information corresponding to all the triggered events belongs to different CCs); the second report reports the information corresponding to all the triggered events of CC4 and CC5 (the second report means that the information corresponding to all the triggered events belongs to different CCs); the third report reports the information corresponding to all the triggered events of CC1; (here, there is no corresponding triggered event in CC2, the third report means that the information corresponding to all the triggered events belongs to the same CC).

[0094] Based on this, if the first information in group K includes For each first event, the terminal device will divide the S first events into K groups; S is a positive integer; here, the division can be based on the event type.

[0095] Here, the S first events can also be divided by the following steps: sort the S first events in a predefined order to obtain a list of first events, and divide the S first events into K groups according to the list of first events; wherein, the predefined order includes priority according to component carrier index or priority according to first event index.

[0096] Here, the S first events can also be divided by the following steps: the S first events are divided into K groups according to the order of component carrier index priority or first event index priority.

[0097] It should be noted that, assuming each of the M CCs has at least one event triggered, and CC#m has N events... m If a number of events are triggered, then there are a total of When an event is triggered, the S events can be divided into K groups; the terminal can send the corresponding CSI information for these K groups on K transmission occasions after the first PUCCH or on K available transmission occasions.

[0098] For example, dividing S events into K groups can be achieved through the following steps:

[0099] Sort the S events in a predefined order to form an event list {event#1, ..., event#S}. Divide all the sorted events into K groups (i.e., before (after)). There are in the group There are 1 event, and the remaining ones are 10. There are in the group (one event);

[0100] Based on this, the S events are sorted in a predefined order as follows:

[0101] The first method: prioritizes the CC index, that is, {the first CC of the first event type, the second CC of the first event type, ..., the G1st CC of the first event type, the first CC of the second event type, ..., the G2nd CC of the second event type, ..., the first CC of the I-th event type, ..., the G1st CC of the I-th event type}. I One CC};

[0102] Wherein, assuming that the i-th event type contains G i The event is triggered on a CC (i = 1, ..., I). The i-th event type refers to the event type with the smallest or largest index among all the event types that the event type satisfies; or the g-th CC with the i-th event type refers to the CC with the smallest or largest index among all the CCs where the i-th event type is triggered.

[0103] The second method: prioritizes the event index, i.e., {the first event of the 1st CC, the second event of the 1st CC, ..., the N1st event of the 1st CC, the first event of the 2nd CC, ..., the N2nd event of the 2nd CC, ..., the first event of the Mth CC, ..., the N1st event of the Mth CC}. M One event};

[0104] Wherein, the m-th CC refers to the CC with the smallest or largest CC index among all CCs where at least one event has been triggered; or, the n-th event in the m-th CC refers to the event with the smallest or largest index associated with the event among the events triggered on the m-th CC.

[0105] For example, in M ​​= 4 CCs, CC#m contains event#{i = 1, ..., N}. M When events are triggered (m = 1, ..., M), they are divided into K = 4 event groups, and events within the same CC are grouped into the same event group. The terminal then sends the CSI information corresponding to the events in the first event group (corresponding to the first CC) on the first transmission occasion or the first available transmission occasion after the first PUCCH; it sends the CSI information corresponding to the events in the second event group (corresponding to the second CC) on the second transmission occasion or the second available transmission occasion, and so on, until the Kth event group (corresponding to the Kth CC) is sent on the Kth available transmission occasion.

[0106] For example, in M ​​= 4 CCs, CC#m contains event#{i = 1, ..., N}. MIf an event is triggered (m = 1, ..., M), then the CCs triggered by event #1 are CCs #{1, 2, 3}, those triggered by event #2 are CCs #{2, 3, 4}, and those triggered by event #3 are CCs #{3, 4}. All events on all CCs are then divided into three groups, each corresponding to one event type: Group 1: {event #1 on CC #1, event #1 on CC #2, event #1 on CC #3}, Group 2: {event #2 on CC #2, event #2 on CC #3, event #2 on CC #4}, and Group 3: {event #3 on CC #3, event #3 on CC #4}. The terminal then sends the CSI information corresponding to the events in Group 1 on the first transmission occasion or the first available transmission occasion after the first PUCCH, and on the second transmission occasion or the second available transmission occasion. On the first transmission occasion, send the CSI information corresponding to the event in group 2, ..., on the third transmission occasion or the third available transmission occasion, send the CSI information corresponding to the event in group 3.

[0107] For example, in M ​​= 4 CCs, CC#m contains event#{i = 1, ..., N}. MWhen triggered (m = 1, ..., M), CC#1 has event#1, CC#2 has event#{1, 2}, CC#3 has event#{2, 3}, and CC#4 has event#{2, 3}. Following the order of method 2 in the lower branch 3, the order is: {event#1 on CC#1, event#1 on CC#2, event#2 on CC#2, event#2 on CC#3, event#3 on CC#3, event#2 on CC#4, event#3 on CC#4}. Assuming it can be divided into K = 4 groups, group 1: {event#1 on CC#1, event#1 on CC#2}, group 2: {event#2 on CC#2, event#2 on CC#3}, group 3: {event#3 on CC#3, event#2 on CC#4}, group 4: {event#3 on CC#4}. Then, the terminal's first transmission after the first PUCCH... On the first available transmission occasion, CSI information corresponding to the event in group 1 is sent; on the second available transmission occasion, CSI information corresponding to the event in group 2 is sent; ... on the fourth available transmission occasion, CSI information corresponding to the event in group 4 is sent.

[0108] In one embodiment, the first information includes one or more of the following:

[0109] Component carrier index (CC Index); Here, the CC index can be indicated in the form of a bitmap, where bit = 0 indicates that no event was triggered on the CC, and bit = 1 indicates that at least one event was triggered on the CC;

[0110] The number of component carriers; at least one event is triggered on the CC here;

[0111] Component carrier group index;

[0112] The number of component carrier groups;

[0113] First event index;

[0114] The number of first events;

[0115] The association between a component carrier or a group of component carriers and the first event; such as the event index triggered on a certain CC or CC group;

[0116] The number corresponding to K is the number of transmission occasions K or the number of groups K.

[0117] It should be noted that since the number of groups is equal to the number of CCs or CC groups, the UE can report only the number of CCs or CC groups, or only the number of transmission occasions K.

[0118] It should be noted that since the number of groups is equal to the number of event types, the UE can report only the number of event types or only the number K of transmission occasions.

[0119] Regarding K, this application can determine it through the following steps: The network device sends second information; wherein the second information includes one or more of the following: the number of uplink control information payloads that the configured second physical uplink channel can carry; the number of component carriers or component carrier groups; and the number of first events. The terminal device receives the second information and determines K based on the second information.

[0120] In some embodiments, the method provided in this application includes the following:

[0121] By sending the content of a CSI report over multiple transmission occasions, a large amount of CSI report information can be sent through a PUSCH with a limited payload. However, extending the transmission time may lead to excessive transmission delay and invalidation of the transmitted CSI content. Therefore, a UCI discarding mechanism can be used, combined with the number of UCI payloads that the second PUSCH can carry in K transmission occasions configured by the base station. This ensures that as much effective CSI content as possible is transmitted, preventing excessive transmission delay, while also maximizing the transmission of CSI.

[0122] Specifically, firstly, multiple CSIs are arranged sequentially according to their priority from highest to lowest, with lower-priority CSIs placed after the bits corresponding to higher-priority CSIs. When the maximum payload size that the PUSCH can carry in K transmission occurrences is less than the payload size of the information reported by the terminal, the terminal needs to discard lower-priority CSIs according to their priority (the terminal device determines the priority of the first information and discards part of the first information based on the priority) until the payload size of the reported information does not exceed the carrying capacity of the PUSCH.

[0123] The granularity of the discarded event includes one of the following: CC; first event type; first event in the component carrier (event on CC).

[0124] In some embodiments, if the granularity of discarding is CC, the first information such as CSI information corresponding to multiple events on multiple CCs each corresponds to a priority. The first information such as CSI information corresponding to different events with the same CC index has the same priority. The terminal device will discard all first information such as CSI information with the same priority.

[0125] In some embodiments, if the granularity of the discard is event type, the first information such as CSI information corresponding to multiple events on multiple CCs each corresponds to a priority. The first information such as CSI information corresponding to the same event type on different CCs has the same priority. The terminal device will discard all first information such as CSI information with the same priority.

[0126] The CSI priority value calculation formula includes a factor of the event that triggers the terminal to report beams, that is, the terminal device determines the priority of the first information based on the first factor; wherein the first factor is related to the event used to trigger or instruct the terminal device to report.

[0127] In some embodiments, if the granularity of the discarded event is an event on a CC, the first information such as CSI information corresponding to multiple events on multiple CCs each corresponds to a priority, and the first information such as CSI information corresponding to events with different event types has different priorities; the first information such as CSI information corresponding to events with different CC indices has different priorities.

[0128] The CSI priority value calculation formula includes a factor of the event that triggers the terminal to report beams, that is, the terminal device determines the priority of the first information based on the first factor; wherein the first factor is related to the event used to trigger or instruct the terminal device to report.

[0129] It should be noted that the first information sent on the K reporting occasions or K available reporting occasions is the first information after the data has been discarded. For example, the content of the CSI report transmitted in K transmission occasions is the CSI content after the data has been discarded.
