Description

Technical Field

[0001] This disclosure relates to a method for processing uplink (UL) transmissions in a communication apparatus and to user equipment (UE). Background Technology

[0002] In traditional beam management procedures, networks can configure / initiate frequent periodic or semi-persistent beam reporting or trigger frequent aperiodic beam reporting to acquire the best / preferred beam for data / control transmissions in a timely manner. However, this significantly leads to substantial UL reporting overhead and control signaling overhead. Furthermore, if less frequent beam reporting is configured, the network may not always acquire the best / preferred beam because UE beam reports may become outdated, resulting in performance degradation. Therefore, implementing beam reporting procedures in a more efficient manner is a key challenge. Summary of the Invention

[0068] Reference will now be made in detail to exemplary embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

[0069] Figure 1According to one embodiment of this disclosure, a framework 100 for UE-initiated / event-driven UL transmission based on trigger mode A is described. If the report transmission mode is configured as trigger mode A, a second UL channel to be transmitted from the network to the UE can be scheduled by the network (e.g., a base station, cell, or gNB), wherein the second UL channel may include a physical uplink shared channel (PUSCH). Specifically, the UE may receive a configuration for UE-initiated / event-driven UL transmission (e.g., channel state information (CSI) report configuration) from the network. The configuration may include an event type, one or more resources for the physical uplink control channel (PUCCH), or information on a set of reference signals (e.g., a set of reference signals for one or more candidate beams). The UE may perform one or more channel measurements based on the configuration and may evaluate one or more execution conditions for triggering the UL transmission according to the configuration. The UE may decide whether to transmit one or more second UL channels based on the measurements. If one or more conditions for triggering UL transmission are met, the UE may transmit a first PUCCH to the network to request one or more resources for one or more second UL channels for UL transmission, wherein the first PUCCH contains at least one bit of data / information. After the first PUCCH ends, the UE may detect a downlink control information (DCI) format from the network, wherein the DCI format may indicate one or more resources for the second UL channels. The UE may receive a physical downlink control channel (PDCCH) and obtain the DCI from the PDCCH after the first PUCCH ends. The UE may transmit the second UL channels through the resources indicated by the DCI, wherein the second UL channels may contain one or more measurement reports (e.g., CSI reports), one or more configuration-related information (e.g., CSI report configuration), or information related to one or more triggering events.

[0070] Figure 2According to one embodiment of this disclosure, a framework 200 for UE-initiated / event-driven UL transmission based on trigger mode B is described. If the report transmission mode is configured as trigger mode B, a second UL channel may be transmitted via one or more pre-configured resources, wherein the second UL channel may contain a configured grant PUSCH (CG-PUSCH). Specifically, the UE may receive a configuration (e.g., CSI report configuration) for UE-initiated / event-driven UL transmission from the network. The configuration may contain information about the event type, one or more resources for the PUCCH, or a set of reference signals. The UE may perform one or more channel measurements based on the configuration and may evaluate one or more execution conditions for triggering UL transmission based on the configuration. The UE may decide whether to transmit one or more second UL channels based on the measurements. If one or more conditions for triggering UL transmission are met, the UE may transmit a first physical uplink control channel (PUCCH) to the network to request one or more resources for one or more second UL channels for UL transmission, wherein the first PUCCH contains at least one bit of data / information. After the first PUCCH ends, the UE may transmit a second UL channel via pre-configured resources, wherein the second UL channel may carry information related to the triggering event. In one example, the second UL channel may contain one or more measurement reports (e.g., CSI reports), one or more configuration-related information (e.g., CSI report configuration), or one or more triggering events-related information.

[0071] In one embodiment, the UE may be configured with one or more triggering events for UE-initiated / event-driven UL transmissions. The triggering events may be associated with one or more event types. For example, for beam management, the quality of beams within the same serving cell may be considered. The triggering events may include: the quality of the current beam (e.g., layer 1 reference signal received power (L1-RSRP)) being worse than a threshold; the quality of at least one new beam (e.g., L1-RSRP) becoming better than the current beam by a threshold value (or offset); the quality of at least one new beam (e.g., L1-RSRP) becoming better than RS by a threshold value, wherein RS is derived from the transmission configuration indicator (TCI) state initiated with the worst quality; and / or the quality of at least one new beam (e.g., L1-RSRP) becoming better than RS by a threshold value, wherein RS is derived from the TCI state initiated with the best quality.

[0072] For example, for L1 / L2 triggered mobility (LTM), the beam quality of different cells can be considered. Triggering events may include: the serving cell's beamforming is worse than an absolute threshold; the candidate cell's beamforming is better than the serving cell's beamforming by an offset (or threshold value); the candidate cell's beamforming is better than an absolute threshold; and / or the serving cell's beamforming is worse than absolute threshold #1 and the candidate cell's beamforming is better than absolute threshold #2, where absolute threshold #1 and absolute threshold #2 may be the same or different.

[0073] In one embodiment, the current beam may include at least one reference signal (e.g., a Synchronization / Physical Broadcast Channel (PBCH) Block (SSB) and / or a Channel State Information Reference Signal (CSI-RS)). The reference signal (RS) may be configured by the gNB (e.g., via higher-layer signals) or determined based on the TCI state of at least one control resource set (CORESET) used to monitor the PDCCH. The reference signal may be implicitly derived from the RS in the indicated TCI state. For example, the current beam may be the RS corresponding to the indicated TCI state, or the current beam may be an SSB, wherein the SSB may be quasi-co-located (QCLed) with the RS corresponding to the indicated TCI state. The TCI state may be indicated by code points included in the TCI field of DCI format 1_1 / 1_2 with / without downlink (DL) allocation. The UE can be configured with dl-OrJointTCI-StateList or ul-TCI-StateList (for example, for unifying the TCI framework).

[0074] The serving cell beam can be: the current beam; one of the current beams with the best quality (e.g., RSRP (e.g., L1-RSRP), reference signal received quality (RSRQ), and / or signal to interference plus noise ration (SINR)); and / or one of the current beams with the worst quality (e.g., L1-RSRP, RSRQ, and / or SINR).

[0075] The beam of a candidate cell may be selected from at least one reference signal (e.g., SSB and / or CSI-RS) configured by the gNB. For example, the beam of a candidate cell may include: one of at least one reference signal with the best quality (e.g., L1-RSRP, RSRQ and / or SINR); and / or one of at least one reference signal with the worst quality (e.g., L1-RSRP, RSRQ and / or SINR).

[0076] Figure 3 A schematic diagram 300 illustrating an indicator for identifying radio link quality is shown according to an embodiment of this disclosure. A UE (e.g., a lower or physical layer) can access the radio link quality of a serving beam / cell and / or a set of candidate beams / cells. For example, the UE can access the radio link quality relative to one or more periodic RSs (e.g., synchronization signals (SS), PBCH, and / or CSI-RS) and one or more thresholds and / or hysteresis parameters. The UE can receive an indicator (e.g., from a lower layer to a higher layer of the UE) indicating that at least one first condition for a candidate beam / cell has been met. At least one first condition (e.g., corresponding to a configuration event) can be met based on the following events: (For example, For comparison Large offset (or threshold); and / or (For example, For comparison (small offset) and / or (For example, For comparison Large offsets), where the aforementioned offsets or thresholds can be configured from the network to the UE via higher-layer signals.

[0077] or ,in For the measurement results of the serving cell / beam (e.g., L1-RSRP, RSRQ and / or SINR), and Based on at least one offset (e.g., cell-specific offset or RS-specific offset) and / or hysteresis parameter (e.g., The offset determined by ( ). For example, It can be the sum of at least one offset and / or hysteresis parameter.

[0078] or ,in For the measurement results of candidate cells / beams (e.g., L1-RSRP, RSRQ, and / or SINR), and Based on at least one offset (e.g., cell-specific offset or RS-specific offset) and / or hysteresis parameter (e.g.) The offset determined by ( ). For example, It can be the sum of at least one offset and / or hysteresis parameter.

[0079] or ,in For the measurement results of the serving cell / beam (e.g., L1-RSRP, RSRQ and / or SINR), and Based on at least one offset (e.g., cell-specific offset or RS-specific offset) and / or hysteresis parameter (e.g., The offset determined by ( ). For example, It can be the sum of at least one offset and / or hysteresis parameter.

[0080] or ,in For the measurement results of candidate cells / beams (e.g., L1-RSRP, RSRQ, and / or SINR), and Based on at least one offset (e.g., cell-specific offset or RS-specific offset) and / or hysteresis parameter (e.g., The offset determined by ( ). For example, It can be the sum of at least one offset and / or hysteresis parameter.

[0081] Thresh1, Thresh2, or at least one of the aforementioned offset or hysteresis parameters (e.g., or It can be configured by higher-level signals from the network (cell-specific or UE-specific).

[0082] It should be noted that in this document, a candidate beam or candidate cell can be considered as a new beam for a new cell. A serving beam or serving cell can be considered as the current beam or current cell, and vice versa. Beams can be associated with reference signals (e.g., CSI-RS and / or SS / PBCH).

[0083] Figure 4 A schematic diagram 400 illustrating indicators for identifying radio link quality is shown according to an embodiment of this disclosure. Reported instances of indicators for candidate cells (e.g., the time interval between two indicators) can be determined based on the period of a reference signal. For example, ,in This indicates the period of the reference signal (e.g., SS / PBCH) of the serving cell, and Indicates the period of the reference signal (e.g., SS / PBCH) of the candidate cell.

[0084] Figure 5 A schematic diagram 500 illustrates the execution conditions of a first UL transmission according to an embodiment of this disclosure. Figure 6 A schematic diagram 600 illustrates the execution conditions of a first UL transmission according to an embodiment of this disclosure. If the first counter / quantity Cn is greater than or equal to a first value... The UE can execute / trigger the first UL transmission (e.g., the first PUCCH) after the first timer expires. That is, if the first counter / quantity Cn is greater than or equal to [a certain value] during the time window / period... The UE can transmit the first UL transmission (the expiration time of the first timer can be equal to the time window), and if the first counter / quantity Cn is less than during the time window / period... The UE may not transmit the first UL transmission, wherein the first timer and / or threshold can be configured to the UE from the network via higher-layer signals. In other words, if the first counter / quantity Cn is greater than or equal to Furthermore, the UE can transmit the first UL transmission before the first timer expires.

[0085] When the first timer is not running (i.e., the corresponding time window has not yet started), the value of the first counter / quantity Cn can be set to 0 or an initial value. After receiving an indication, the UE can increment the first counter / quantity Cn. For example, the UE can increment the first counter / quantity from 0 to 1 (or set the first counter / quantity to 1) after receiving an indication. When the first counter / quantity Cn is equal to 1 or after receiving an indication, the first timer can be set to a value. (For example, the first timer or corresponding time window may be started or restarted.) The first counter / quantity Cn may indicate how many instances (e.g., consecutive instances) of an indicator (e.g., from a lower layer), where the indicator indicates that at least one first condition (e.g., the condition corresponds to an event type configured to the UE) of at least one candidate cell / beam has been met. The UE may reset the first counter / quantity Cn (e.g., set it to 0) after the first timer (or corresponding time window) expires or after triggering the first UL transmission.

[0086] For example, suppose It equals 5. (Refer to...) Figure 5 Because the first counter / quantity Cn = 5 becomes greater than or equal to 5 during the time window. The UE can decide to trigger a UL transmission (e.g., the first PUSCH). See reference... Figure 6 Since the first counter / quantity Cn = 3 is less than 3 during the time window... The UE can decide not to trigger UL transmission.

[0087] This disclosure is intended to discuss stop conditions (used for: stopping transmission on the second UL channel; or conditions for resetting counters / quantities / timers), configuration of event-triggered UL transmissions, and resources for event-driven UL transmissions (TX) (handling of multiple triggering events / configurations and collisions), such as Figure 7 As shown, where Figure 7 A schematic diagram 700 illustrating the configuration of UL transmission is shown according to an embodiment of this disclosure.

[0088] Figure 8 A schematic diagram 800 illustrating a stop condition is provided according to an embodiment of this disclosure. After the UE transmits a first PUCCH to request one or more resources for one or more second UL channels (e.g., CG-PUSCH, PUCCH, or PUSCH), the UE may execute / trigger one or more second UL transmissions. When a stop condition (e.g., a condition corresponding to an event type configured to the UE) is met, the UE may stop the transmission of the second UL channels, and the UE may reset a first counter / quantity Cn and / or a first timer. For example, the UE may increment the value of the counter / quantity Kn after a second UL channel transmission. If the counter / quantity Kn becomes greater than or equal to a preset value (e.g., 5), the UE may determine that the stop condition has been met. The UE may stop the transmission of the second UL channels accordingly. That is, the UE may stop the transmission of the second UL channels after reaching the required number of transmissions for the second UL channels.

[0089] Figure 9 A schematic diagram 900 illustrating a stop condition is provided according to an embodiment of this disclosure. In trigger mode A, the second UL channel is scheduled by the gNB. The UE can detect the DCI format (or medium access control (MAC) control element (CE)) indicating the second UL channel resource. The second UL channel can be a valid CG-PUSCH / PUCCH or a PUSCH scheduled by the DCI, wherein the DCI can indicate to the UE whether the CG-PUSCH / PUCCH is valid. The DCI can indicate that the uplink shared channel (UL-SCH) is not transmitted on the PUSCH / CG-PUSCH. The second UL channel can be a PUCCH initiated by the DCI (or MAC-CE). The UE can transmit the second UL channel via the resource indicated by the DCI. If at least one stop condition is met, the UE can decide to stop UL transmission.

[0090] Figure 10A schematic diagram 1000 illustrating a stop condition is provided according to an embodiment of this disclosure. In trigger mode B, the second UL channel is transmitted via pre-configured resources. The second UL channel may be a PUSCH, CG-PUSCH, or PUCCH. The UE may transmit the second UL channel via resources pre-configured to the UE. If at least one stop condition is met, the UE may decide to stop UL transmission.

[0091] In one embodiment, the UE may determine that a stop condition (e.g., a stop condition for a first UL channel or a second UL channel) has been met based on the following event: the UE receives an indicator for updating at least one beam (e.g., via MAC-CE), wherein the indicator may be an activation / deactivation of a TCI state for a UE-specific PDCCH or a UE-specific PDSCH TCI state, wherein the UE may transmit a hybrid automatic repeat request corresponding to the indicator. After receiving a HARQ (HARQ) request acknowledgment (ACK), the UE stops UL transmission; the UE receives an indicator indicating the TCI state (e.g., via DCI format 1_1 / 1_2 with / without DL allocation) (e.g., when the UE is configured with unifiedTCI-StateType, dl-OrJointTCI-StateList and / or ul-TCI-StateList for unified TCI state operation, where unifiedTCI-StateType can indicate the unified TCI state type as dl-OrJointTCI-StateList or ul-TCI-StateList), wherein the indicated TCI state may be different from the previously indicated TCI state; the UE receives a PDCCH command for initiating a random access procedure (e.g., via DCI format 1_0), wherein the cell indicator field in the PDCCH command can indicate a candidate cell (e.g., the cell corresponding to the execution condition that triggers UL transmission); and / or the UE receives a cell handover command (e.g., via MAC-CE in PDSCH), wherein the UE may stop UL transmission after transmitting a HARQ-ACK corresponding to the indicator (e.g., PDSCH). In one embodiment, the UE may reset the counter / quantity or set the value of the counter / quantity to 0 when receiving an indicator, wherein the counter / quantity may include counter / quantity Kn, first counter / quantity Cn or second counter / quantity Cm, which will be described in the following paragraphs.

[0092] In one embodiment, if the UE receives an indication to stop transmission on the second UL channel, the UE may determine that the stop condition has been met. The UE may determine that the stop condition has been met based on the following events: if the second UL channel is a CG-PUSCH, the UE may receive a DCI indicating that the CG-PUSCH verification has been released; if the second UL channel is a PUCCH, the UE may receive a DCI or MAC-CE indicating that the PUCCH verification has been released; and / or if the second UL channel is a PUSCH scheduled by the DCI, the UE may determine the number of transmissions on the second UL channel (e.g., based on higher-layer configurations, such as the pusch-AggregationFactor or fields in the DCI, such as time domain resource allocation (TDRA)). The UE may stop transmission on the second UL channel after the number of transmissions on the second UL channel has been reached.

[0093] In one embodiment, when the UE is configured with cell discontinuous reception (DRX) and the transmission timing of the second UL channel is within the duration of cell DRX shutdown: the UE may stop the transmission of the second UL channel, or the UE may continue to transmit the second UL channel (e.g., according to gNB configuration).

[0094] Figure 11 A schematic diagram 1100 illustrating a stop condition according to an embodiment of this disclosure states that the stop condition occurs if the number of transmissions in the second UL channel (e.g., the value of a counter / quantity Kn) or the transmission timing is greater than or equal to a pre-configured value. (For example, =5), the UE can determine that the stopping condition has been met. The UE can report that the quality of the new beam (e.g., the first new beam or the second new beam) has become better than the current beam by a threshold value by transmitting a second UL channel to the network. The UE can increment a counter / quantity Kn after transmitting the second UL channel. For example, suppose... =5. The UE can report the quality of the first new beam to the network four times, and the counter / quantity Kn can increase from 1 to 4. Then, if there is a state update (e.g., the quality of the second new beam becomes better than the current beam), the UE can report the quality of the second new beam to the network, and the counter / quantity Kn can increase to 5. Since the counter / quantity Kn becomes equal to... The UE may decide to stop UL transmission, and the UE may reset the first counter / quantity Cn accordingly.

[0095] Figure 12 A schematic diagram 1200 illustrating a stop condition according to an embodiment of this disclosure. If in There is no state update during (or after) the transmission period, and the transmission period of the second UL channel is greater than or equal to [the specified duration]. (For example, = 5), the UE can determine that the stopping condition has been met. The UE can report that the quality of a new beam (e.g., a first or second new beam) has become better than the current beam by a threshold value by transmitting a second UL channel to the network. The UE can increment a counter / quantity Kn after transmitting the second UL channel. If there is a state update (e.g., the quality of another new beam becomes better than the current beam), the UE can reset the counter / quantity Kn. For example, suppose... = 5. The UE can report the quality of the first new beam to the network four times, and the counter / quantity Kn can increase from 1 to 4. Then, due to a state update, the UE can reset the counter / quantity Kn, and then the UE can report the quality of the second new beam to the network and increase the counter / quantity Kn accordingly. After the UE reports the quality of the second new beam five times, the counter / quantity Kn can increase to 5. Since the counter / quantity Kn becomes equal to... And in If there is no state update during the transmission period, the UE may decide to stop UL transmission, and the UE may reset the first counter / quantity Cn accordingly. When the second UL channel is transmitted due to the first new beam / cell satisfying the trigger event, if no other beam / cell (e.g., the second new beam) satisfies the trigger event, the UE may stop transmitting the second UL channel. For example, after the UE reports the quality of the first new beam four times (i.e., Kn = 4), if the second new beam does not satisfy the trigger event, the UE may stop transmitting the second UL channel.

[0096] Figure 13 A flowchart illustrating the transmission of the second UL channel is described according to an embodiment of this disclosure. Figure 14 A schematic diagram 1400 illustrating the stopping conditions according to an embodiment of this disclosure is shown. (Refer to...) Figure 13 and Figure 14 In step S1301, the UE may receive configuration (e.g., CSI report configuration) for UE-initiated / event-driven UL transmission from the network. In step S1302, the UE may perform measurements (e.g., channel measurements) according to the configuration. In step S1303, the UE may determine, based on the measurement results, that at least one condition for triggering the UL transmission has been met. The at least one condition for triggering the UL transmission may be similar to... Figure 5 At least one condition mentioned in the above. In step S1304, the UE may start or restart the second timer or reset the second counter / quantity Cm in response to determining that at least one second condition has been met. In step S1305, the UE may perform a measurement according to the configuration. When the UE receives an indication that at least one second condition has been met, the UE may increment the second counter / quantity Cm by 1. At least one second condition may be similar to Figure 3At least one first condition mentioned in the above. In step S1306, the UE may determine that the second timer expires. After the second timer expires, in step S1307, the UE may determine whether the second counter / quantity Cm is greater than or equal to If the second counter / quantity Cm is greater than or equal to The UE can determine that at least one condition for triggering the second UL channel transmission has been met. Accordingly, the UE can perform the second UL channel transmission, and the UE can again execute step S1304 to restart the second timer or reset the second counter / quantity. If the second Cm is less than... The UE can decide that the stop condition has been met, and if there is a second UL channel to transmit, the UE can stop transmitting the second UL channel, as shown in step S1308.

[0097] Specifically, if the second counter / quantity Cm is greater than or equal to the threshold, the UE can execute / trigger the second UL channel transmission (e.g., PUSCH, CG-PUSCH, or PUCCH) after the second timer expires. In other words, if the second counter / quantity Cm is greater than or equal to the threshold within the time window / period (the expiration time of the second timer can be equal to the time window), then... The UE can transmit through the second UL channel, and if the second counter / quantity Cm is less than [a certain value] within the time window / period. The UE may not transmit a second UL channel, wherein the second timer and / or threshold may be configured from the network to the UE via a higher-layer signal.

[0098] When the second timer is not running (i.e., the corresponding time window has not yet started), the value of the second counter / quantity Cm can be set to 0 or the initial value. After receiving the indicator, the UE can increment the second counter / quantity Cm. For example, the UE can increment the second counter / quantity from 0 to 1 after receiving the indicator. When the second counter / quantity Cm is equal to 1 or after receiving the indicator, the second timer can be set to a value. (For example, the second timer may be started or restarted.) The second counter / quantity Cm may indicate how many instances (e.g., consecutive instances) of an indicator (e.g., from a lower layer) have been met, where the indicator indicates that at least one second condition (e.g., a condition corresponding to an event type configured to the UE) for at least one candidate cell / beam has been met. The UE may reset the second counter / quantity Cn (e.g., set it to 0) after the second timer (or corresponding time window) expires or after triggering the second UL transmission.

[0099] In one embodiment, after determining that at least one second condition has not been met, the UE may reset the first counter / quantity Cn and / or the second counter / quantity Cm.

[0100] Figure 15A schematic diagram 1500 illustrating a stop condition is provided according to an embodiment of this disclosure. In one embodiment, the UE may start or restart a second timer or reset a second counter / quantity Cm after receiving an offset T from an indicator, wherein the indicator may indicate that at least one condition for triggering UL transmission has been met.

[0101] In one embodiment, the UE may stop the transmission of the second UL channel based on the following events: the number of second UL channel transmissions (Kn) is greater than or equal to a pre-configured value Kmax; the time period used for transmitting the second UL channel is greater than or equal to a pre-configured value (e.g., 5 milliseconds or a time slot); and / or the second counter / number Cm is less than a second value after the second timer expires. (or equal to 0). Otherwise, the UE may transmit a second UL channel and start or restart the second timer after the second timer expires. The second counter / quantity Cm may represent how many (e.g., consecutive) instances of an indicator (e.g., from a lower layer) indicating that at least one second condition of at least one candidate cell / beam has been met. The UE may start or restart the second timer based on the following event (e.g., set to). One or more conditions used to trigger UL transmission have been met (e.g., after the first timer expires and / or the first counter / quantity Cn is greater than or equal to a first value). (After); after transmitting the first PUCCH; upon receiving the DCI indicating the second UL channel resources; and / or during the first (or Xth) transmission of the second UL channel, where X is a positive integer. The UE may reset the second counter / quantity Cm (e.g., set it to 0) when the second timer starts or restarts.

[0102] "The second counter / quantity Cm is less than the second value after the second timer expires." The condition "(or equal to 0)" can be expressed as: "The second counter / quantity Cm is in the time period or time window (e.g., (The value within) is less than the second value (or equal to 0).

[0103] In one embodiment, at least one first condition and at least one second condition are the same.

[0104] In one embodiment, at least one first condition and at least one second condition correspond to different sets of offset values ​​and / or different sets of hysteresis parameters.

[0105] In one embodiment, the UE may report its ability to support this mechanism (e.g., the aforementioned stop condition). The same concept may be applied to embodiments disclosed later.

[0109] Figure 19 A flowchart illustrating the second UL channel transmission in trigger mode A is provided according to an embodiment of this disclosure. Figure 20 A schematic diagram 2000 illustrating a stopping condition according to an embodiment of this disclosure. (Refer to...) Figure 19 and Figure 20 In step S1901, the UE may receive configuration (e.g., CSI report configuration) for UE-initiated / event-driven UL transmission from the network. In step S1902, the UE may perform measurements (e.g., channel measurements) according to the configuration. In step S1903, the UE may determine, based on the measurement results, that at least one condition for triggering the UL transmission has been met. In step S1904, the UE may start or restart a second timer or reset a second counter / quantity Cm in response to determining that at least one second condition has been met. In step S1905, the UE may perform measurements according to the configuration. When the UE receives an indicator indicating that at least one second condition has been met, the UE may increment the second counter / quantity Cm by 1. In step S1906, the UE may determine that the second timer has expired. After the second timer expires, in step S1907, the UE may determine whether the second counter / quantity Cm is greater than or equal to... If the second counter / quantity Cm is greater than or equal to The UE can determine that at least one condition for triggering the transmission of the second UL channel has been met. Therefore, the UE can perform the transmission of the second UL channel, and the UE can repeat step S1904 to restart the second timer or reset the second counter / quantity.

[0110] If the second Cm is less than In step S1908, the UE may decide whether to receive an indicator for transmitting the second UL channel (before the second timer expires). The indicator may contain information for transmitting the second UL channel during the second timer (e.g., The UE schedules the DCI for the second UL channel before the timer expires. If the UE receives the DCI during the time window (i.e., before the second timer expires), the UE can execute step S1909. If the UE does not receive the DCI, the UE can execute step S1910. In step S1909, the UE can transmit the second UL channel during at least one transmission opportunity, and then the UE can stop transmitting the second UL channel after at least one transmission opportunity. In step S1910, the UE can stop transmitting the first PUCCH. In other words, if the UE receives the DCI (e.g., before the second timer expires), the UE can perform the transmission of the second UL channel during at least one transmission opportunity, even if one or more stop conditions are met. Otherwise, due to the satisfaction of one or more stop conditions, the UE can stop transmitting the first PUCCH used to request the second UL channel.

In step S2102, the UE may perform measurements (e.g., channel measurements) according to the configuration. In step S2103, the UE may determine, based on the measurement results, that at least one condition for triggering UL transmission has been met. In step S2104, the UE may start or restart a second timer or reset a second counter / quantity Cm (e.g., in response to determining that at least one second condition has been met). In step S2105, the UE may perform measurements according to the configuration. When the UE receives an indicator indicating that at least one second condition has been met during the time window corresponding to the second timer, the UE may restart the second timer. In step S2106, the UE may determine whether the second timer has expired. If the second timer has not expired, the UE may repeat step S2105 to continuously monitor whether one or more second conditions have been met. If the second timer expires, the UE may execute step S2107. In step S2107, the UE may determine that the stop condition has been met and may stop transmitting the second UL channel.

[0113] like Figure 22 As shown, the value of the second timer can change over time from... Decrease. However, if the UE receives an indicator before the second timer expires, the UE can reset the value of the second timer to [value missing]. In one embodiment, the UE may restart the second timer after receiving an indicator following the fulfillment of one or more conditions for triggering UL transmission (e.g., transmission of the second UL channel).

The UE may start the second timer during or after the transmission of the first PUCCH (e.g., set to...). When the UE receives an indicator (e.g., from a lower layer) indicating that at least one second condition of a candidate cell has been met, the UE may restart the second timer (e.g., reset it to...). ).

Figure 27 and Figure 28 In step S2801, the UE may receive configuration (e.g., CSI report configuration) for UE-initiated / event-driven UL transmission from the network. In step S2802, the UE may perform measurements (e.g., channel measurements) according to the configuration. In step S2803, the UE may determine, based on the measurement results, that at least one condition for triggering the UL transmission has been met. In step S2804, the UE may start or restart a second timer in response to determining that at least one second condition has been met. In step S2805, the UE may perform measurements according to the configuration. When the UE receives an indicator indicating that at least one second condition has been met, the UE may restart the second timer. In step S2806, the UE may determine whether the second timer has expired. If the second timer has not expired, the UE may repeat step S2805 to continuously monitor whether one or more second conditions have been met. If the second timer expires, the UE may execute step S2807.

[0120] In step S2807, the UE may decide whether to receive an indicator for transmitting the second UL channel (before the second timer expires). The indicator may contain a DCI for scheduling the second UL channel (e.g., before the second timer expires). If the UE receives the DCI during the time window (i.e., before the second timer expires), the UE may execute step S2808. If the UE does not receive the DCI, the UE may execute step S2809. In step S2808, the UE may transmit the second UL channel during at least one transmission opportunity, and then the UE may stop transmitting the second UL channel after at least one transmission opportunity. In step S2809, the UE may stop transmitting the first PUCCH. In other words, if the UE receives the DCI (e.g., before the second timer expires), the UE may perform the transmission of the second UL channel during at least one transmission opportunity, even if one or more stop conditions are met. Otherwise, due to the satisfaction of one or more stop conditions, the UE may stop transmitting the first PUCCH used to request the second UL channel.

The first PUCCH may be associated with one or more CSI reporting configurations (or one or more trigger event configurations). Furthermore, each of the CSI reporting configurations (or trigger event configurations) may be associated with a different second UL channel. The resources of the first PUCCH may be indicated by an ID (e.g., scheduling request ID), where the ID may be indicated by a configuration (e.g., CSI reporting configuration).

[0137] Figure 33A schematic diagram 3300 illustrating a first PUCCH and a second UL channel is provided according to an embodiment of this disclosure. Different first PUCCHs may be associated with different CSI reporting configurations (or different trigger event configurations). Furthermore, each of the CSI reporting configurations (or trigger event configurations) may be associated with a different second UL channel. The resources of the first PUCCH may be indicated by an ID (e.g., scheduling request ID), where the ID may be indicated by a configuration (e.g., a CSI reporting configuration). For example, a configuration (such as CSI reporting configuration #1 or trigger event configuration #1) may indicate first PUCCH #1, and another configuration (such as CSI reporting configuration #2 or trigger event configuration #2) may indicate first PUCCH #2. Each configuration may be applied to the transmission of the corresponding second UL channel (e.g., within a cell group). For example, CSI reporting configuration #1 or trigger event configuration #1 may be applied to the transmission of second UL channel #1, and CSI reporting configuration #2 or trigger event configuration #2 may be applied to the transmission of second UL channel #2.

[0138] Figure 34 A schematic diagram 3400 illustrating a first PUCCH and a second UL channel (e.g., for CSI reporting) according to an embodiment of this disclosure is shown. The first PUCCH may be associated with one or more CSI reporting configurations (or one or more trigger event configurations). Furthermore, each of the CSI reporting configurations (or trigger event configurations) may be associated with the same second UL channel. In one example, Figure 34 The CSI report configuration (or trigger event configuration) described herein may be within the same cell group. The resources of the first PUCCH may be indicated by an ID (e.g., scheduling request ID), where the ID may be indicated by a configuration (e.g., CSI report configuration). In this case, each of the CSI report configurations may be configured with the same ID for the first PUCCH. The first PUCCH (or CSI report) may contain at least one of the following: an indication of a request for resources for the second UL channel; at least one cell ID; at least one configuration ID (e.g., trigger event configuration, CSI report configuration, or LTM CSI report configuration); at least one RS ID; at least one RSRP (e.g., L1-RSRP); at least one differential RSRP (e.g., L1-RSRP); and / or at least one event ID. For example, the CSI report configuration may contain at least one event type or at least one event ID. One or more configurations associated with the first PUCCH may be applied to the transmission of the second UL channel (e.g., within the cell group). For example, CSI report configuration #1, trigger event configuration #1, CSI report configuration #2 and / or trigger event configuration #2 can be applied to the same second UL channel transmission.

[0139] Figure 35 A schematic diagram 3500 illustrating a first PUCCH and a second UL channel (e.g., for CSI reporting) according to an embodiment of this disclosure is shown. Different first PUCCHs may be associated with different CSI reporting configurations (or different trigger event configurations). Furthermore, each of the CSI reporting configurations (or trigger event configurations) may be associated with the same second UL channel. The resources of the first PUCCH may be indicated by an ID (e.g., scheduling request ID), where the ID may be indicated by a configuration (e.g., CSI reporting configuration). For example, a configuration (such as CSI reporting configuration #1 or trigger event configuration #1) may indicate first PUCCH #1, and another configuration (such as CSI reporting configuration #2 or trigger event configuration #2) may indicate first PUCCH #2. One or more configurations, each associated with one or more first PUCCHs, may be applied to the transmission of the second UL channel (e.g., in a cell group). For example, CSI reporting configuration #1, trigger event configuration #1, CSI reporting configuration #2, and / or trigger event configuration #2 may be applied to the transmission of the same second UL channel.

[0140] Figure 36 A schematic diagram 3600 illustrates collision handling for first PUCCHs with different configurations according to an embodiment of this disclosure. The UE can receive multiple CSI report configurations, each indicating a corresponding event type. When multiple events / configurations all meet the conditions (or event types) for a UE-initiated / event-driven UL report, the UE can prioritize one event / configuration and transmit the corresponding first PUCCH (or information in the first PUCCH) based on the following information: cell index / ID; configuration index / ID; and / or event index / ID (or event type). For example, an event triggered by the primary cell (PCell) or a cell with a smaller ID may have a higher priority than other cells. For example, a smaller configuration / event ID or a predefined event ID / type may have a higher priority. Figure 36 As shown, the priority of the first PUCCH corresponding to cell #1 can be higher than the priority of the first PUCCH corresponding to cell #2. If a first PUCCH is configured for multiple CSI report configurations (e.g., configurations for event-driven UL transmissions), then the first PUCCH corresponding to cell #1 can be the same as the first PUCCH corresponding to cell #2.

[0141] Figure 37A schematic diagram 3700 illustrates collision handling for a first PUCCH corresponding to different configurations according to an embodiment of this disclosure. The UE can receive multiple CSI report configurations, each indicating a corresponding event type. When all multiple events / configurations satisfy the conditions (or event types) for a UE-initiated / event-driven UL report, the UE can transmit information related to the multiple events / configurations via the first PUCCH. For example, the first PUCCH may contain information related to configuration #1 (e.g., the ID of configuration #1) and configuration #2 (e.g., the ID of configuration #2).

[0142] In one embodiment, when the UE is configured in trigger mode B and the report configuration type is configured, for example, as CSI report configuration, as PUSCH upper half-persistent, the second UL channel may be CG-PUSCH (or half-persistent PUSCH). The UE may receive a higher-layer configuration (or higher-layer signal) from the network and determine the PUSCH resources based on the higher-layer configuration (e.g., ConfiguredGrantConfig). The trigger event configuration or CSI report configuration may be associated with the higher-layer configuration. The trigger event configuration or CSI report configuration may indicate the ID of the higher-layer configuration. In other examples, the higher-layer configuration may indicate the ID of the trigger event configuration or the ID of the CSI report configuration. The higher-layer configuration may provide at least one of the following information for determining PUSCH resources: time-domain resource allocation; frequency-domain resource allocation; modulation order; target code rate and / or transport block (TB) size; PUSCH period; and / or PUSCH time-domain offset.

[0143] If the second UL channel is a PUSCH such as CG-PUSCH (e.g., configured by gNB), the higher-layer configuration may configure the following information to the UE: the ID of the higher-layer configuration (e.g., ConfiguredGrantConfig); at least one CSI report configuration ID; time-domain resource allocation; frequency-domain resource allocation; modulation order, target code rate and / or TB size; PUSCH period; and / or PUSCH time-domain offset.

[0144] In one embodiment, the UE may determine the payload size (e.g., number of bits) and resources (e.g., time / frequency resources and / or periodicity) of the second UL channel based on the DCI (e.g., trigger mode A) for scheduling the second UL channel. For example, the DCI may indicate at least one of the following for determining the payload size: a trigger event configuration ID or a CSI report configuration ID; a trigger event ID; and / or a cell ID. In one embodiment, the UE may determine the payload size and resources of the second UL channel based on the fact that the trigger event configuration (or CSI report configuration) for transmitting the first PUCCH condition has been satisfied (e.g., trigger mode B). For example, suppose a configuration (e.g., trigger event configuration or CSI report configuration) ID in the first PUCCH corresponds to a second UL channel. The UE may determine the payload size and resources of the second UL channel based on the configuration corresponding to the configuration ID.

[0145] In one embodiment, the UE may determine the payload size (e.g., number of bits) of the second UL channel based on one or more trigger event configurations (e.g., all trigger event configurations configured for the UE). In other words, the UE may determine the payload size of the second UL channel based on the set of CSI report configurations associated with the first PUCCH or the second UL channel. For example, the UE may determine the payload size as the maximum payload size in the configurations. For example, suppose one or more configurations configured for the UE (e.g., trigger event configurations or CSI report configurations) correspond to a second UL channel. The UE may determine the maximum payload size among all configurations as the payload size of the second UL channel.

[0146] Figure 38 A schematic diagram 3800 illustrating the scheduling of a second UL channel according to an embodiment of this disclosure is provided. In one embodiment, the first transmission opportunity of the second UL channel may not be earlier than a period of time (e.g., T≥0) after the UE transmits the first PUCCH (or after the first PUCCH ends), where the period T may be the number of symbols determined by the UE based on the subcarrier spacing (e.g., the subcarrier spacing of the second UL channel). In other words, the second UL channel may be the first of the available transmission opportunities after a period T from the end of the first PUCCH. The UE may be configured to trigger mode B.

[0147] Alternatively, suppose the UE is configured in trigger mode B and the report type on the PUCCH is configured by a configuration (e.g., CSI report configuration) to be periodic or semi-persistent. If the second UL channel is a PUCCH, the UE can determine the PUCCH resource or transmission period based on the configuration (e.g., CSI report configuration).

[0148] In one embodiment, the first PUCCH and the second UL channel can be transmitted on the same serving cell. In another embodiment, the first PUCCH and the second UL channel can be transmitted on different serving cells. For example, if the second UL channel is a PUSCH, the UE can transmit the first PUCCH and the second UL channel via different serving cells.

[0149] In one embodiment, the second UL channel can be transmitted on different serving cells at different transmission times. For example, if the second UL channel is a PUCCH and the UE is configured with a PUCCH switching secondary cell (PUCCH-sSCell) (e.g., for PUCCH cell handover), the UE can transmit the second UL channel on different serving cells at different transmission times.

[0150] In one embodiment, the UE may report its capabilities to the network to indicate whether the UE supports trigger mode A and / or trigger mode B for UE-initiated reporting or event-driven reporting.

[0151] In one embodiment, the UE may report its capabilities to the network to indicate whether the UE supports periodic PUCCH, semi-persistent scheduling (SPS) PUCCH, SPS PUSCH, and / or dynamic PUSCH as a second UL channel.

[0152] Figure 39 A schematic diagram 3900 illustrates collision handling of uplink control information (UCI) corresponding to different configurations in a second UL channel according to an embodiment of this disclosure. When multiple events corresponding to different configurations (e.g., CSI reporting configuration) satisfy one or more conditions (or event types) for UE-initiated / event-driven UL reporting, the UE can determine at least one event or configuration for UL reporting (e.g., measurement reporting) via the second UL channel. The UE can select at least one event or configuration based on a cell index, a configuration (e.g., CSI reporting configuration) index / ID, and / or an event ID / type. In one embodiment, a cell corresponding to one or more events triggered for a PCell or a cell with a smaller cell ID may have a higher priority than other cells. In one embodiment, a smaller configuration / event ID or a predefined event ID / type may have a higher priority.

[0153] For example, the UE can decide that the priority of the second UL channel of cell #1 is higher than the priority of the second UL channel of cell #2 because the ID of cell #1 is lower than the ID of cell #2. Therefore, the UE can transmit the second UL channel of cell #1 first. After the stop condition of cell #1 is met, the UE can transmit the second UL channel of cell #2.

[0154] In one embodiment, if one or more lower priority events or configurations still satisfy one or more conditions for triggering an event, then one or more lower priority events or configurations may be transmitted by the second UL channel after the stop conditions of one or more priority events or configurations are satisfied.

[0155] In one embodiment, the UE may be configured with at least one triggering event for UE-initiated / event-driven reporting. The triggering event may include: the current beam quality (e.g., L1-RSRP) being worse than a certain threshold; at least one new beam quality (e.g., L1-RSRP) becoming better than the current beam by a threshold value (or offset); at least one new beam quality (e.g., L1-RSRP) becoming better than RS by a threshold value, where RS is derived from the initiation TCI state with the worst quality; and / or at least one new beam quality (e.g., L1-RSRP) becoming better than RS by a threshold value, where RS is derived from the initiation TCI state with the best quality. In one embodiment, multiple triggering events may be associated with the same or different timers. For example, the UE may receive an indicator indicating a triggering event and may start or restart a timer (e.g., a first timer or a second timer) in response to the indicator, where the timer may include timer #1 and timer #2. If the UE determines that the indicator indicates the L1-RSRP of the new beam becomes better than the current beam by a threshold value, the UE may start or restart timer #1. If the UE determines that the indicator indicates that the L1-RSRP of the current beam is less than a certain threshold, the UE can start or restart timer #2.

[0156] In one embodiment, the UE may be configured (e.g., configured by CSI reporting) to have at least one event for UE-initiated / event-driven reporting (e.g., the current beam quality is worse than a certain threshold, or at least one new beam quality becomes better than the current beam by a threshold value).

[0157] The UE can determine the payload size and / or set of fields used for reporting based on the configuration (e.g., CSI fields such as the number of reports (the number of CSI reports configured to be associated with UE-initiated / event-driven reporting of a cell / cell group), the number of beams / cells in the report). If any of at least one event satisfies the reporting conditions, the same set of fields can be used (e.g., transmitted via a second UL channel). For example, up to two events can be configured in the configuration (e.g., CSI reporting configuration).

[0158] In one embodiment, the UE may be configured with both Event-1 (e.g., the current beam quality is worse than a certain threshold) and Event-2 (e.g., at least one new beam quality becomes better than the current beam by a threshold value (or offset)) for UE-initiated / event-driven reporting. The UE may determine the payload size and / or set of fields (e.g., CSI) used for reporting (e.g., the number of reports or the number of beams / cells reported). If either Event-1 or Event-2 satisfies the reporting conditions, the set of fields may be used.

[0159] Figure 40 A schematic diagram illustrating the CSI field in CSI report 400 is provided according to an embodiment of this disclosure. The CSI field in CSI report 400 may include: a cell ID; an event / configuration ID (e.g., a CSI report configuration ID); one or more RS IDs (e.g., RS#1, RS#2, RS#L×M), where each RS ID corresponds to a reference signal satisfying an event; one or more measurement reports (e.g., (differential) RSRP (e.g., L1-RSRP), RSRQ, or SINR, such as RSRP / RSRQ / SINR#1, differential RSRP (e.g., L1-RSRP) / RSRQ / SINR#2, differential RSRP (e.g., L1-RSRP) / RSRQ / SINR#L×M); and / or one or more capacity indices (e.g., capacity index #1, capacity index #L×M). RS may include an SS / PBCH block resource indicator (SSBRI) or a CSI-RS resource indicator (CRI). L is the number of reported cells, where L can be a fixed value (e.g., 1) or provided by a higher-level configuration (e.g., CSI reporting configuration or LTM CSI reporting configuration). M is the number of RS and RSRP (e.g., L1-RSRP) / RSRQ / SINR / capacity index pairs reported per cell, where M can be a fixed value or configured by a higher-level configuration (e.g., CSI reporting configuration or LTM CSI reporting configuration).

[0160] In one embodiment, a maximum of one event-triggered configuration (or CSI reporting configuration) can be configured in a cell. For example, an event-triggered configuration can be configured in a cell based on UE capabilities reported by the UE.

[0161] In one embodiment, a maximum of one event-triggered configuration (or CSI reporting configuration) can be configured in a cell group. For example, an event-triggered configuration can be configured in a cell group based on the UE capabilities reported by the UE.

[0162] In one embodiment, multiple event-triggered configurations (or CSI reporting configurations) corresponding to a single purpose can be configured (within a cell group). When a UE is configured with more than one event-triggered configuration (e.g., for one or more serving cells respectively), the multiple event-triggered configurations can correspond to the same purpose (e.g., for beam management). For example, multiple triggering configurations can be configured in a cell group based on the UE capabilities reported by the UE. The UE capability report may include the maximum number of cells that can be configured in the same time period.

[0163] In one embodiment, multiple event triggering configurations (or CSI reporting configurations) corresponding to multiple purposes can be configured (within a cell group). When a UE has multiple event triggering configurations configured for multiple serving cells (e.g., two event triggering configurations), the multiple event triggering configurations can correspond to different purposes (e.g., for beam management and LTM respectively). For example, multiple triggering configurations can be configured in a cell group based on the UE capabilities reported by the UE.

[0164] In one embodiment, multiple event-triggered configurations can be configured (within the cell). For example, multiple event-triggered configurations can be configured within the cell based on UE capabilities reported by the UE.

[0165] In one embodiment, multiple event triggering configurations corresponding to multiple purposes can be configured (within the cell). When the UE has multiple event triggering configurations configured for the serving cell (e.g., two event triggering configurations), the multiple event triggering configurations can correspond to different purposes (e.g., beam management and LTM respectively). For example, multiple event triggering configurations corresponding to multiple purposes can be configured in the cell based on the UE capabilities reported by the UE.

[0166] In one embodiment, a single trigger event can be configured in a configuration (e.g., a CSI report configuration). For example, a single trigger event can be configured in the configuration based on the UE capabilities reported by the UE.

[0167] In one embodiment, multiple triggering events can be configured in a configuration (e.g., a CSI report configuration). For example, multiple triggering events can be configured in the configuration based on the UE capabilities reported by the UE.

[0168] In one embodiment, the UE can report whether it supports an event-triggered configuration type (or event type, CSI report configuration type) and one or more corresponding values ​​(e.g., in the case of configuring a configuration type) for UE-initiated / event-driven reporting capabilities. For example, parameters reporting a first event-triggered configuration type (e.g., beam management) capability may include: the maximum number of candidate beams in the serving cell. For example, parameters reporting a second event-triggered configuration type (e.g., LTM) capability may include: the maximum number of candidate cells; and / or the maximum number of beams in the candidate cells.

[0169] In one embodiment, the UE can report whether it supports the ability to combine different event-triggered configuration types (or multiple event types, or different CSI reporting configuration types) and one or more corresponding values ​​(e.g., in the case of configuring multiple configuration types) for UE-initiated / event-driven reporting. For example, parameters for reporting the capability of a first event-triggered configuration type (e.g., beam management) may include: the maximum number of candidate beams. For example, parameters for reporting the capability of a second event-triggered configuration type (e.g., LTM) may include: the maximum number of candidate cells; and / or the maximum number of beams in the candidate cells.

[0170] In one embodiment, the UE can report the capability to support multiple event-triggered configurations (or multiple event types, multiple CSI reporting configurations) of the same configuration type and corresponding values ​​(e.g., in the case of multiple configuration types). For example, parameters reporting the capability of a first event-triggered configuration type (e.g., beam management) may include: the maximum number of supported configurations / cells; and / or the maximum number of candidate beams in the configuration. For example, parameters reporting the capability of a second event-triggered configuration type (e.g., LTM) may include: the maximum number of candidate cells; and / or the maximum number of beams in the candidate cells. For the second event-triggered configuration type (e.g., LTM): the maximum number of supported configurations / cells; the maximum number of candidate cells in the configuration; and / or the maximum number of beams in the candidate cells in the configuration.

[0171] In one embodiment, when the first PUCCH and PUSCH collide within the same time period: the UE may discard the first PUCCH; and / or the UE may transmit a MAC-CE via the PUSCH. The MAC-CE can be used to request a second UL channel resource for UL transmission. The MAC-CE may contain at least one of the following: a cell ID; a configuration ID; and / or at least one event ID.

[0172] In one embodiment, when the second UL channel carrying the CSI corresponds to a triggering event, and if the second UL channel and the PUCCH carrying the second UCI collide within the same time period: the UE may transmit the CSI and the second UCI (e.g., HARQ ACK or a CSI containing at least one of RSRP (e.g., L1-RSRP), RSRQ, or SINR) on the second UL channel; the UE may transmit the CSI on the second UL channel and discard the PUCCH carrying the second UCI (e.g., containing at least one of rank indicator (RI), channel quality indicator (CQI), and precoding matrix indicator (PMI) or containing at least one of RSRP (e.g., L1-RSRP), RSRQ, or SINR); the UE may transmit the PUCCH carrying the second UCI (e.g., scheduling request (SR) or HARQ ACK) and discard the second UL channel; and / or if the second UL channel and the PUCCH correspond to different priority indices, the UE may transmit the channel with the higher priority index.

[0173] In one embodiment, when the second UL channel carrying the CSI corresponds to a triggering event, and if the second UL channel and the PUSCH collide within the same time period: the UE may multiplex the CSI in the PUSCH and discard the second UL channel, wherein an indicator may be multiplexed in the PUSCH along with the UL signal, wherein the indicator may indicate whether the UL signal is multiplexed in the PUSCH; the UE may transmit the second UL channel and discard the PUSCH; the UE may transmit the PUSCH and discard the second UL channel; and / or if the PUSCH and the second UL channel correspond to different priority indices, the UE may transmit the one with the higher priority index of the PUSCH and the second UL channel.

[0174] In one embodiment, the UE may indicate a beam failure of the serving cell via a second UL channel for link recovery. For example, the UE may indicate at least one of the following: the serving cell's cell ID; a first predetermined value (e.g., all zeros) for the serving cell's current / serving beam quality (e.g., RSRP (e.g., L1-RSRP), RSRQ, or SINR); identification of the serving cell's reference signal (e.g., SSBRI or CRI), where the reference signal may also be one of the RSs configured in candidateBeamRSList for link recovery; and / or a second predetermined value (e.g., all 1s) for the reference signal quality (e.g., RSRP (e.g., L1-RSRP), RSRQ, or SINR). For example, the beam failure indication for link recovery may have a higher priority than other triggering events. A triggering event configuration may be configured for UEs in a cell group.

In step S411, a first channel state information (CSI) report configuration is received from the network, wherein the first CSI report configuration includes at least one of an event type, resources of the physical uplink control channel (PUCCH), or a set of reference signals. In step S412, at least one measurement is performed on the set of reference signals according to the first CSI report configuration. In step S413, a decision is made on whether to transmit the PUCCH based on the at least one measurement.

[0176] Figure 42 A flowchart illustrating a method for processing UL transmissions by a communication apparatus according to an embodiment of this disclosure is provided, wherein the method may be applicable to a UE or a base station. In step S421, a first channel state information (CSI) report configuration is received from the network, wherein the first CSI report configuration includes at least one of an event type, resources of a physical uplink control channel (PUCCH), or a set of reference signals. In step S422, at least one measurement is performed on the set of reference signals according to the first CSI report configuration. In step S423, if the value is greater than or equal to a first threshold and a timer has not expired (e.g., within a time period), the PUCCH is transmitted, wherein the first threshold or timer is configured by a higher-layer signal.

[0177] Figure 43A schematic diagram of a communication device is illustrated according to an embodiment of this disclosure, wherein the communication device may be implemented as a UE or base station (e.g., a network or node) as described above. Communication device 430 may include a processor 431, a storage medium 432, and a transceiver 433. Processor 431 is coupled to storage medium 432 and transceiver 433. Processor 431 may be configured to at least implement as described above. Figure 1-42 The methods described herein, as well as their exemplary embodiments and alternative variations.

[0178] Processor 431 can be implemented using programmable units, such as microprocessors, microcontrollers, digital signal processors (DSPs), field-programmable gate arrays (FPGAs), etc. The functions of processor 431 can also be implemented using discrete electronic devices or ICs. It should be noted that the functions of processor 431 can be implemented in hardware or software.

[0179] Storage medium 432 may be, for example, any type of fixed or removable random access memory (RAM), read-only memory (ROM), flash memory, hard disk drive (HDD), solid-state drive (SSD), or similar element, or a combination thereof, configured to record multiple modules or various applications that can be executed by processor 431.

[0180] Transceiver 433 can be configured to transmit and receive signals in radio frequency. Transceiver 433 can also perform operations such as low-noise amplification, impedance matching, frequency mixing, up- or down-frequency conversion, filtering, and amplification. Transceiver 433 may include one or more digital-to-analog (D / A) converters or analog-to-digital (A / D) converters configured to convert from analog signal format to digital signal format during uplink signal processing and from digital signal format to analog signal format during downlink signal processing. Transceiver 433 may include an antenna array containing one or more antennas for transmitting and receiving omnidirectional or directional antenna beams.

[0181] In this disclosure, the first PUCCH is not limited to a PUCCH. For example, the first PUCCH may be a sounding reference signal (SRS) or a physical random-access channel (PRACH).

[0182] In this disclosure, the serving cell may be a PCell or a primary secondary cell (PSCell), but is not limited to these.

[0183] In this disclosure, the term "SS / PBCH" may be replaced by "SSB" and vice versa.

[0184] In this disclosure, "setting the first timer to" This indicates that the UE can start or restart the first timer, and the first timer is configured as follows: The same concept can be applied to other timers.

[0185] In this disclosure, the term "A / B" means "A and / or B".

[0186] In this disclosure, combinations of embodiments should not be excluded.

[0187] Based on the above, the disclosed UE can decide whether to perform UL transmission based on CSI report configuration. The UE can determine the number of trigger events based on timers and counters, and initiate a beam reporting procedure based on the number of trigger events. Given that the UE has better and more timely knowledge of beam quality changes, a UE-initiated beam reporting procedure or an event-driven beam reporting procedure executed by the UE can result in more timely beam reporting while reducing reporting overhead. Under this procedure, 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 triggering frequent reports.

[0188] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
