[0016] In legacy beam management procedures, the network may configure / activate frequent periodic or semi-persistent beam reporting (e.g., N best beams) or trigger frequent aperiodic beam reporting to acquire the best / preferred beam for data / control transmissions. However, this may result in large UL reporting overhead and control signaling overhead. At the same time, if less frequent beam reporting is configured, the network could not always acquire the ‘best / preferred’ beam (s) as the beam reporting by the UE may be outdated, thus leading to performance degradation. Given that UE has better and more timely knowledge of downlink (DL) beam quality and DL beam quality variations, the UE-initiated beam reporting (UEIBR) procedure can lead to more timely beam reports with reduced reporting overhead.
[0017] UEIBR procedure may be triggered based on the detection or occurrence of an event. The UE may measure and compare the reference signals associated with the current and another DL beams (e.g., new beam) . An event (Event-2) may be detected when the quality of at least one new beam is better than that of the current beam. The current beam may be the activated downlink (DL) beam that the network uses for DL communication with the UE. The new beam may be a configured beam that UE monitors as a candidate beam for beam switching. The quality of a beam may be based on a measurement of the layer 1-reference signal received power (L1-RSRP) or signal-to-interference-and-noise ratio (SINR) . The quality of the new beam may be considered to be better than that of the current beam when the quality of the new beam is a threshold value better than that of the current beam. For example, the difference between the quality of the new beam and the current beam’s quality is larger than the threshold. In some instances, an event (Event-1) may be detected when the quality of the current beam falls below a threshold.
[0018] UEIBR operation may include two transmissions: a first transmission for scheduling requests or sending a notification to the network and a second transmission to carry the report. The second transmission may be paired with the first transmission such that the resources or transmission occasion of the second transmission may be determined based on the transmission occasion or resources of the first transmission. In a carrier aggregation operation, the first and second transmissions of UEIBR may be scheduled on different component carriers (CCs) . UE may inform the network whether it supports the transmission of UEIBR-related measurements or transmissions on different CCs. The network may apply restrictions or requirements for UEIBR operation.
[0019] To trigger UEIBR operation, UE may perform measurements on the reference signal associated with the current beam or the new beam. In some examples, UEIBR is triggered when the number of detected events exceeds a threshold. However, measurement resources, e.g., reference signals, may change. For example, radio resource control (RRC) signaling may reconfigure reference signals of current or new beams. In some embodiments, the event evaluation procedure is reset upon detecting a change in measurement resources.
[0020] In some examples, UE may support UE-initiated and network (NW) -initiated (or NW-triggered) reports. In some embodiments, downlink (DL) control signaling is provided to allow both UE-initiated and NW-initiated beam reports.
[0021] In some instances, UE may schedule transmission of UE-initiated beam report and other uplink control information (UCI) , e.g., hybrid automatic repeat request-acknowledgment (HARQ-ACK) or periodic or semi-persistent channel state information (CSI) , on the transmission occasion for second transmission of UEIBR. In some embodiments, multiplexing procedure and prioritization criteria is described to enable transmission of UE-initiated beam report and other UCIs.
[0022] Finally, the 3GPP TSs introduce quasi-co-location (QCL) relationships between different reference signals or beams. QCL relationship may indicate that certain characteristics of these signals or beams are closely related or identical. In some embodiments, measurement resource configuration, and report encoding for Event-1 measurement and detection is provided. For example, UE may use a reference signal that is in QCL relation with the reference signal of the current beam to perform the measurement for UEIBR triggering event detection, e.g., Event-1.

[0033] FIG. 1 illustrates a network environment 100 in accordance with some embodiments. The network environment 100 may include a UE 104 communicatively coupled with a base station 108 of a radio access network (RAN) 110. The UE 104 and the base station 108 may communicate over air interfaces compatible with 3GPP TSs, such as those that define a Fifth Generation (5G) new radio (NR) system or a later system. The base station 108 may provide user plane and control plane protocol terminations toward the UE 104.
[0034] The network environment 100 may further include a core network 112. For example, the core network 112 may comprise a 5th Generation Core network (5GC) or a later generation core network. The core network 112 may be coupled to the base station 108 via a fiber optic or wireless backhaul. The core network 112 may provide functions for the UE 104 via the base station 108. These functions may include managing subscriber profile information, subscriber location, authentication of services, or switching functions for voice and data sessions.
[0035] The network environment 100 may further include a data network 120. Data network 120 may include a system of interconnected nodes that facilitate data transmission between UE 104 and various application servers and other service providers. The base station 108 and the core network 112 may route application data between the UE 104 and external data network 120 or application servers. These application servers host web applications, cloud storage, and multimedia streaming services, which communicate with the UE 104 via standardized protocols and interfaces defined by 3GPP, ensuring secure and efficient data exchange.
[0036] The frequency resources may be partitioned into component carriers (CCs) . Component carriers are individual frequency bands within the radio spectrum that are aggregated to form a larger bandwidth, thereby enhancing data throughput. Each component carrier can have a bandwidth, for example, a CC may have a bandwidth ranging from 1.4 Mega Hertz (MHz) and up to 100 MHz. In a carrier aggregation scenario, multiple CCs are combined, allowing the UE 104 to utilize a broader bandwidth than what a single carrier would provide.
[0037] The primary cell (PCell) is the main cell within a carrier aggregation setup, responsible for handling the primary control and signaling functions for the UE 104. The PCell is typically the cell that the UE 104 initially connects to, and it remains active throughout the connection. PCell may provide control channels and reference signals for the UE 104. In the context of carrier aggregation or dual connectivity, PCell may also be referred to as the primary serving cell (PSCell) .
[0038] Secondary cells (SCells) are additional cells that can be added to the UE’s connection to increase the available bandwidth and improve data throughput. SCells are used primarily for data transmission and are activated or deactivated based on the network’s resource management decisions.
[0039] Special cell (SpCell) or the primary cell within the SCell group in an NR dual connectivity or carrier aggregation may provide similar functionalities to the PCell but within the secondary cell context.
[0040] SCell group and SpCell groups may refer to the grouping of SCells and the management of their configurations. The configuration of these groups allows for efficient resource utilization and enhanced performance through coordinated scheduling and management of multiple carriers. SCells and SpCells may be configured dynamically by network 102 based on various factors such as the UE’s capability, network load, or quality of service requirements.
[0041] The configuration parameters and operational states of these cells are communicated to UE 104 via radio resource control (RRC) signaling.
[0042]
[0043] UE 104 may perform UE-initiated beam reporting (UEIBR) operation. In performing UEIBR, UE 104 may autonomously measure and report beam quality information to network 102. The reporting may allow network 102 to perform beam management, including beam selection and switching. UE 104 may perform event-driven UE-initiated beam management, e.g., UEIBR. UE 104 may periodically perform event evaluation operations. Event evaluation may be performed at time instances, and each time instance may be referred to as an event evaluation instance (EEI) . Once an event is detected, a beam report transmission procedure may be triggered, e.g., a UEIBR operation. UE 104 may support the following modes for UEIBR operations: Mode A or Mode B.
[0044] UE 104 may support Mode A UEIBR operation. In Mode A, UE 104 may perform two transmissions, a first and a second transmissions. The first transmission may include a flag of one or more bits to request one or more uplink (UL) resources for the second transmission. UE 104 may receive control or configuration information from network 102. The control or configuration information may include UL scheduling information, such as time and frequency resources for the second transmission. UE 104 may generate a beam report and transmit the beam report via the second transmission.
[0045] In some instances, the first transmission is a first physical uplink control channel (PUCCH) . The first PUCCH may carry one-bit UL control information (UCI) to request UL resources. The mechanism is similar to the UL scheduling request (SR) described in the 3GPP TSs. The UE may detect the downlink (DL) control information (DCI) format. The CI may indicate UL resources for the second transmission. The second transmission may be via a physical uplink shared channel (PUSCH) .
[0046] UE 104 may support Mode B UEIBR operation. In Mode B, UE 104 may be configured with resources (e.g., transmission occasions) for a second transmission. Therefore, UE 104 may not need to request resources for the second transmission. Consequently, UE 104 may not need to monitor or receive DL control or configuration information to determine the resources for the second transmission. UE 104 may generate and send the first transmission to notify network 102 of the second transmission, including a beam report. The notification may allow network 102 to only monitor UL resources associated with the first transmission that includes a notification. In some instances, there is a deterministic or one-to-one mapping between the resources of the first transmission and those of the second transmission. Therefore, from the resources of the first transmission, UE 104 and network 102 may determine the resources of the second transmission. UE may send a beam report via the second transmission of UEIBR operations.
[0047] The transmission occasions associated with the first transmission of the UEIBR operation may be scheduled on a first CC, and the transmission occasion (s) associated with the second transmission of the UEIBR operation may be scheduled on a second CC. In some embodiments, UE 104 may generate and transmit UE capability report to network 102. UE capability report may indicate whether UE 104 supports transmission occasions of the first and second transmission of the UEIBR on different CCs or CC groups.
[0048] UE 104 may perform an event evaluation procedure to monitor events that trigger UEIBR operations. The event evaluation procedure may include performing measurements on reference signals of the current beam and the new beam and determining whether an event (e.g., Event-1 or Event-2) is detected. In some instances, network 102 may change the resources of the reference signals associated with the event evaluation procedure. UE 104 may reset the event evaluation procedure.
[0049] In Mode A of UEIBR operation, the resources for the second transmission of UEIBR operation may be allocated by downlink control information (DCI) . Network 102 may use DCI to schedule the NW-initiated beam report and UE-initiated beam report. In some embodiments, network 102 may use a CSI request field in DCI for resource indication and scheduling of the NW-initiated and UE-initiated beam reports.
[0050] In some instances, other UCIs (e.g., HARQ-ACK, periodic CSI report, or semi-persistent CSI report) may be carried with a UE-initiated beam report using the second transmission of the UEIBR operation. Some embodiments describe conditions for multiplexing the UE-initiated beam report with other UCIs. Prioritization rules are also described to resolve collision and multiplex UE-initiated beam reports with other UCIs.
[0051] In some embodiments, measurement resource configuration and report encoding for Event-1 measurement and detection are provided. For example, UE 104 may use a reference signal that is in QCL relation with the reference signal of the current beam to perform the measurement for UEIBR triggering event detection, e.g., Event-1. Different approaches are described for the UE-initiated beam report when Event-1 is triggered.
[0052] FIG. 2 illustrates carrier aggregation configurations 200 in accordance with some embodiments. Carrier aggregation configurations 200 include Case 1 and Case 2 for the CC location of the first and second transmission of the UEIBR operation.
[0053] The first transmission (or the transmission occasions of the first transmission) and the second transmission (or the transmission occasions of the second transmission) may be on the same CC or different CCs.
[0054] In one example, the first transmission of the UEIBR operation is a PUCCH transmission, and the second transmission of the UEIBR operation is a PUSCH transmission. The PUCCH may be transmitted on a PCell or a PUCCH SCell (in case of carrier aggregation with PUCCH SCell configured) or PSCell (in case of Evolved Universal Terrestrial Radio Access Network-Dual Connectivity (EN-DC) or NR-DC) ) . PUCCH SCell may be referred to as an SCell that is configured with a PUCCH.
[0055] In some instances, the CC where the first transmission is transmitted is termed as first-transmission-CC. The CC where the second transmission is transmitted may be referred to as second-transmission-CC. A group of SCells whose PUCCG signaling is associated with the PUCCH on the PUCCH SCell may be referred to as the PUCCH-SCell group, and a group of cells whose PUCCH signaling is associated with the PUCCH on a SpCell may be called SpCell group.
[0056] In some embodiments, first-transmission-CC and second-transmission-CC may be on the same CC or CC group. For example, first-transmission-CC and second-transmission-CC may be in the PUCCH-SCell group or SpCell group. This is motivated by the fact that CCs in the PUCCH SCell group or SpCell group may be implemented by separate hardware and can not have timely cross-talk.
[0057] UE 104 may expect that the first transmission is configured for transmission on a first CC, the second transmission is configured for transmission on a second CC, and that the first CC and the second CC are the same. UE 104 may not expect the first CC to be different from the second CC.
[0058] In some embodiments, the first-transmission-CC and the second-transmission-CC may be in the same or different cell groups. For example, the first transmission CC may be in the PCCH-SCell group, the second transmission CC may be in the SpCell group, and vice versa.
[0059] Case 1 and Case 2 are examples of carrier aggregation where four CCs are configured, CC0–CC3. CC0 is the SpCell. CC0 and CC1 are in the SpCell group. CC2 is a PUCCH-SCell, and CC2 and CC3 are in a PUCCH-SCell group.
[0060] In case 1, the first transmission is on CC0, and its paired second transmission (e.g., the second transmission corresponding to the first transmission) is on CC1. In Case 1, first-transmission-CC, CC0, and second-transmission-CC, CC1, are both in the same cell group, e.g., SpCell.
[0061] In case 1, another first transmission is also allocated on CC2, and its paired second transmission is allocated on CC3. Therefore, the first-transmission-CC, CC2, and second-transmission-CC, CC3, are also both in the same cell group, e.g., the PUCCH-SCell group.
[0062] In case 2, the first transmission is on CC0, and its corresponding second transmission is on CC2. Therefore, the first and second transmissions are on different cell groups, one in the SpCell group and the other in the PUCCH-SCell group.
[0063] In some embodiment, UE 104 may generate and transmit a UE capability report to network 102. The UE capability report may indicate whether the first-transmission-CC and the second-transmission-CC in different cell groups or different CCs are supported by the UE 104.
[0064] FIG. 3 illustrates timing diagram 300 for event evaluation procedure resetting for user equipment (UE) -initiated beam reporting (UEIBR) operation in accordance with some embodiments.
[0065] The UE 104 may measure the reference signal (RS) associated with the quality of a beam (and compare it with the quality of the current beam) at event evaluation instances (EEIs) . For example, EEI i-1, i, 0, 1, 2, or 3 in FIG 3.
[0066] At each EEI, UE 104 may evaluate whether an Event-1 or an Event-2 is detected. In some instances, UE 104 may count the number of detected UEIBR-triggering events. UE 104 may trigger UEIBR operation when the number of detected events (e.g., Event-1 or Event-2) is larger than a threshold. The value of the threshold may be configured by network 102. In some instances, UE 104 may trigger the UEIBR operation when the number of consecutive detected events is larger than a threshold. In another example, UE 104 may determine an event evaluation window, count the number of detected events within the event evaluation window, and trigger the UEIBR operation if the number of detected events within the event evaluation window exceeds the threshold. UE 104 may implement a counter to count the number of detected events. In another example, UE 104 may implement a counter to count the number of EEIs within an event evaluation window, e.g., counter value i-1, i, 0, 1, 2, 3, in FIG. 3. The value of the counter may be the same as the index of EEIs.
[0067] In some embodiments, UE 104 may reset the evaluation procedure when UE 104 detects a condition. Resetting the evaluation procedure may include resetting the counter associated with the evaluation procedure, e.g., the counter that is counting the number of detected events or the counter that is counting the EEIs. When the UE 104 resets an evaluation procedure, the event evaluation window associated with the evaluation procedure may also be reset and determined for the new instance of the evaluation procedure. UE 104 may resent the evaluation procedure when UE 104 detects a condition. For example, at T310, UE 104 may detect a condition and reset the evaluation procedure.
[0068] UE 104 may reset the evaluation procedure when UE 104 detects one or more of the following conditions. A first condition may be detected when a configuration for a measurement reference signal associated with the evaluation procedure is provided. For example, a first condition is met when a reconfiguration provides a new configuration of a reference signal of the new beam or the current beam. Network 102 may send an RRC reconfiguration to change the current beam or the reference signal of the current beam used for event evaluation. The reconfiguration of the active current beam or the reference signal of the current beam may trigger resetting the evaluation procedure. In another example, network 102 may reconfigure UE 102 and change the candidate new beam or reconfigure the reference signal of the new beam associated with the evaluation procedure. The reconfiguration of the new beam or the new beam’s reference signal may trigger the evaluation procedure’s resetting.
[0069] A second condition may be detected when the indicated transmission configuration indicator (TCI) -state is changed. TCI may define a quasi-co-location (QCL) relationship between a source and a target reference signal. The beam configuration may indicate a reference signal associated with the beam. The configuration may also include a TCI state field that determines one or more reference signals (referred to as QCL reference signals) that are in QCL relationship with the beam’s configured reference signal. In some embodiments, UE 104 may use the QCL reference signals to perform measurements associated with the evaluation procedure. UE 104 may reset an evaluation procedure when the TCI state of the current beam or the new beam is changed. For example, when the QCL source reference signal of the new TCI-state is different from that of the previous TCI-state.
[0070] In some embodiments, Network 102 may configure UE 104 with different schemes for measurement resource determination for the current beam in Event-1. In scheme 1, the reference signal for the current beam is the QCL reference signal in the indicated TCI state. In Scheme 2, the reference signal for the current beam is the synchronization signal block (SSB) , which is QCL-ed with the QCL reference signal in the indicated TCI state.
[0071] UE 104 may generate a UEIBR report when event-1 has triggered the UEIBR operation. In some embodiments, UE 104 may use an absolute measurement report, referred to as option 1. UEIBR report may include a 7-bit field to report the measurement report. For example, UE 104 may use an absolute L1-RSRP report defined by a 7-bit value. The 7-bit value may determine the absolute L1-RSRP report in the range [-140, -44] decibel milliwatt (dBm) with 1 decibel (dB) step size.
[0072] In another embodiment, UE 104 may use differential reporting. The UEIBR report may include a 4-bit field to report the differential report with reference to the threshold, which is referred to as option 2. The threshold may be configured, e.g., by RRC signaling. In some examples, the threshold may be the same as that of Event-1. For example, UE 104 may use a differential L1-RSRP reporting. The differential value may be defined by a 4-bit value with 2 dB step size with respect to a reference value, e.g., the threshold.
[0073] In some embodiment, UE 104 may be configured to use option 1 or option 2 for reporting for Event-1. For example, Network 102 may use RRC signaling to configure UE 104 with option 1 or option 2 reporting. In some instances, network 102 may use CSI report configuration in RRC signaling to configure UE 104.
[0074] A third condition may be detected when UE 104 receives a UL grant that allocates the resources for a second transmission in response to a first transmission. For example, at T330, UE 104 may receive a UL grant associated with the first transmission at T320. UE 104 may reset the evaluation procedure at T330. In some instances, this condition may be applicable to Moda A only. Once the UE 104 receives a UL grant, it indicates that the evaluation procedure has triggered a UEIBR operation, and a new evaluation procedure may start to monitor for triggering the next instance of the UEIBR operation. In some embodiments, UE 104 may reset the evaluation operation after the second transmission of the UEIBR.
[0075] FIG. 4 illustrates a signaling diagram 400 for resource indication of UEIBR operation in accordance with some embodiments. Signaling diagram 400 is an example of signaling that indicates the resources for the second transmission of UEIBR in Mode A.
[0076] UE 104 performs event evaluation during the event evaluation window EEW1. UE 104 may detect one or more UEIBR operation-triggering events, e.g., Event-1 or Event-2. At 410, UE 104 may generate and send the first transmission of UEIBR operation, e.g., a scheduling request. At 420, UE may receive an UL grant from network 102. In response to the first transmission of UEIBR operation, network 102 may generate and transmit the UL grant to UE 104. The UL grant may be a downlink control information (DCI) , e.g., DCI format 0_1 or 0_2.
[0077] The UL grant may determine the resources for the second transmission of the UEIBR operation. At T430, UE 104 may generate and transmit the UEIBR report using the resources allocated by the L grant for the second transmission.
[0078] In some embodiments, the UL grant includes the UEIBR dedicated field (Alt. 1 in Table 1 of FIG. 4) . The UEIBR dedicated field in the UL grant may indicate the resources for the second transmission of the UEIBR operation in Mode A. The dedicated field may be a dedicated CSI request codepoint associated with a UE-initiated beam report configuration. For example, network 102 may use RRC signaling to configure UE 104, including a configuration that indicates the association between a dedicated CSI request codepoint and a UE-initiated beam report configuration (s) . Once UE 104 receives the dedicated CSI request field in the UL grant, e.g., DCI format, UE 104 may transmit the corresponding UE-initiated report in the resources indicated by the dedicated CSI request field.
[0079] In some embodiments, the UL grant may include a field associated with both a UEIBR report and a network (NW) -initiated beam report, e.g., a network-initiated CSI report configuration., e.g., Alt. 2 in Table 1 in FIG. 4. UE 104 may apply a mapping order to determine which report can be transmitted in the indicated resources. Mapping may resolve the collision when both the NW-initiated beam report and the UEIBR report are scheduled to use the same resources, e.g., time or frequency resources.
[0080] In some embodiments, the mapping order may be predefined, e.g., by the 3GPP TSs. For example, UE 104 may first map the NW-initiated beam report and then the UEIBR report. In another example, UE 104 may first map the UEIBER report and then the NW-initiated beam report.
[0081] In some embodiments, UE 104 may determine the mapping order based on the report ID value associated with each report. For example, a report with a larger report ID (compared to the other report ID) may be mapped first. In one example, the UEIBR report may have a report ID that is greater than that of the network-initiated beam report. In this case, UE 104 may map the UEIBR first. In another example, UE 104 may first map a report associated with a smaller report ID (compared to the other report ID) .
[0082] Table 1 is an example of using a dedicated CSI request codepoint (Alt. 1) for resource indication of UEIBR report or a CSI request codepoint for resource indication for UEIBR and NW-initiated beam reports.
[0083] The codepoints “00” and “01” may be only used for legacy NW-initiated beam reports. In one example, Alt. 1, codepoint “10” is used as a dedicated resource indication. In this case, the codepoint “10” may not triggered by the legacy NW-initiated beam report and may only be used for the UEIBR report. In another example, Alt. 2, codepoint “10” is used for legacy NW-initiated beam and UEIBR reports. In this case, codepoint “10” may indicate a second set of aperiodic (AP) -CSI reports. Codepoint “10” may also indicate UEIBR associated with CSI report configuration with identifier (ID) #1.
[0084] FIG. 5 illustrates a multiplexing operation 500 for uplink control information multiplexing. The multiplexing operation 500 is an example of generating the report for the second transmission of the UEIBR operation in Mode B.
[0085] In some embodiments, when the UEIBR is in MODE B, the second transmission may be scheduled on a Type-1 PUSCH transmission occasion configured by RRC signaling. Type-1 PUSCH may be a configured grant (CG) that allows UE 104 to transmit the UL transmission without a UL grant or DCI triggering.
[0086] In some instances, Type-1 PUSCH may be transparent to a medium access control (MAC) layer and may not be used for UL-shared channels (UL-SCH) .
[0087] In some instances, UE 104 may schedule uplink control information (UCI) such as (HARQ-ACK, periodic CSI report, or semi-persistent CSI report) to be transmitted at the same time as the UE-initiated beam report.
[0088] In some embodiments, UE 104 may determine one report and transmit that report only. UE 104 may determine the report based on the priority of the report. In some instances, the priority is a relative priority and may be predefined, e.g., in the 3GPP TSs. For example, UEIBR may have a higher priority than the periodic CSI report, or HARQ-ACK may have a higher priority than the aperiodic (AP) -CSI report. In one example, the priority may be absolute, e. s., based on a priority index associated with a report. Network 102 may configure the priority index associated with each report. For example, network 102 may use RRC signaling to configure the priority index of each report. In one example, UEIBR may be associated with a priority index that is greater than that of HARQ-ACK. UE 104 may determine and select the report with the highest priority (relative or absolute) .
[0089] In some embodiments, UE 104 may multiplex two or more reports in one report transmitted by the second transmission of UEIBR operation. In some instances, UE 104 may multiplex UEIBR with other UCIs when the UEIBR is triggered and included in the report. In this case, if the UEIBR report is not ready or the UEIBR is not triggered, other UCIs may not be transmitted using the resources allocated for the second transmission of the UEIBR operation.
[0090] In some instances, UE 104 may multiplex other UCIs even when no UEIBR event is triggered, or no UEIBR report is available. UE 104 may multiplex other UCIs in the report and transmit on the transmission occasion associated with the UEIBR operation. In this case, the report may be generated and transmitted without a UEIBR report.
[0091] When multiplexing, UE 104 may include as many reports as the resources’ capacity. For example, UE 104 may determine the number of bits that can be transmitted via the second transmission and may select the as many bits of UEIBR and other UCI reports that the resources can carry. If there are excess reports that cannot be carried, UE 104 may drop those reports. UE 104 may start loading the report based on the priority order of the reports and load the report until no additional bits can be included. UE 104 may drop the unloaded or partially loaded reports.
[0092] In the example in FIG. 5, UEIBR has the highest priority, followed by HARQ-ACK, followed by the AP-CSI report, and the periodic CSI report has the lowest priority. UE 104 may multiplex UEIBR and HARQ-ACK in the report and determine that no additional report can be included in the multiplexed report. UE 104 may transmit the report, including the UEIBR and HARQ-ACK. UE 104 may drop the untransmitted reports, e.g., the AP-CSI and periodic CSI reports.
[0093] In some embodiments, the highest priority value may be assigned to the UEIBR report. In this case, the UEIBR report may be prioritized over other UCI types, e.g., priority of UEIBR report> priority of HARQ-ACK> priority of NW-configured CSI reports. That is, the priority of the UEIBR report is greater than that of HARQ-ACK, and the priority of HARQ-ACK is greater than the priority of NW-configured CSI reports (e.g., AC-CSI report or periodic CSI report) .
[0094] In some embodiments, the priority rule may be defined as priority of HARQ-ACK> priority of UEIBR report> priority of NW-configured CSI report. That is, the priority of HARQ-ACK is greater than that of UEIBR report, and the priority of UEIBR report is greater than that of NW-configured CSI reports (e.g., AP-CSI report or periodic CSI report) .
[0095] In some embodiments, the priority of UEIBR may be determined based on the content of the UEIBR report. For example, when the UEIBR report includes L1-RSRP quantity, the UEIBR report may be associated with the priority of L1-RSRP quantity, e.g., as defined in the 3GPP TSs.
[0096] FIG. 6 illustrates an operation flow / algorithmic structure 600 in accordance with some embodiments. The operation flow / algorithmic structure 600 is related to the configuration of the first and second transmission of UEIBR operation in carrier aggregation. The operation flow / algorithmic structure 600 may be performed or implemented by a UE such as, for example, the UE 104 or UE 1200; or components thereof, for example, baseband processor circuitry 1204A.
[0097] The operation flow / algorithmic structure 600 may include, at 610, generating a UE capability report associated with the UEIBR operation. The UE capability report may include information to indicate that the UE 104 supports the first transmission of the UEIBR operation to be transmitted on a first component carrier (CC) and a second transmission associated with the first transmission of the UEIBR operation to be transmitted on a second CC.
[0098] UE 104 may receive and process a configuration including a first configured CC associated with the first transmission and a second configured CC associated with the second transmission. UE 104 may determine an expectation that the first configured CC is the same as the second configured CC. UE 104 may determine a first configured CC group associated with the first transmission or first CC and a second configured CC group associated with the second transmission or second CC. UE 104 may determine an expectation that the first configured CC group is the same as the second configured CC group.
[0099] The operation flow / algorithmic structure 600 may include, at 620, generating a first signal for transmission on the first CC. UE 104 may detect a UEIBR triggering event and initiate a UEIBR operation. UE 104 may generate a first signal for the first transmission of UEIBR on the first CC. The first signal may be a scheduling request (in the case of UEIBR Mode A or a notification in the case of UEIBR Mode B) .
[0100] The operation flow / algorithmic structure 600 may include, at 630, generating a second signal for transmission on the second CC. UE 104 may determine the transmission occasion associated with the second transmission and generate a report to be transmitted to network 102 via the second transmission of the UEIBR.
[0101] In generating the report, UE 104 may multiplex the UEIBR report with other UCI reports. UE 104 may determine the UCIs and UEIBR report to be included in the report based on thier priorities.
[0102] FIG. 7 illustrates an operational flow / algorithmic structure 700 in accordance with some embodiments. The operation flow / algorithmic structure 700 is related to the configuration of the first and second transmission of UEIBR operation in carrier aggregation. The operation flow / algorithmic structure 700 may be performed or implemented by a base station such as for example, the network 102, the base station 108, or the base station 1300; or components thereof, for example, baseband processor circuitry 1304A.
[0103] The operation flow / algorithmic structure 700 may include, at 710, processing a UE capability report associated with a UEIBR operation. Network 102 may receive a UE capability report from UE 104. The UE capability may include information indicating whether a first transmission of UEIBR operation on a first CC and a second transmission of UEIBR operation on a second CC is supported.
[0104] The operation flow / algorithmic structure 700 may include, at 720, generating a configuration. Network 102 may generate a configuration that includes an indication that the first transmission of the UEIBR operation is to be transmitted on the first CC or the second transmission associated with the UEIBR operation is to be transmitted on the second CC.
[0105] In some embodiments, the first CC is the same as the second CC. In some embodiments, the first CC is in a first CC group, and the second CC is in a second CC group, and the first and second CC groups are the same.
[0106] FIG. 8 illustrates an operation flow / algorithmic structure 800 in accordance with some embodiments. The operation flow / algorithmic structure 800 is related to the event evaluation procedure reset for the UEIBR operation. The operation flow / algorithmic structure 800 may be performed or implemented by a UE such as, for example, the UE 104 or UE 1200; or components thereof, for example, baseband processor circuitry 1204A.
[0107] The operation flow / algorithmic structure 800 may include, at 810, performing an evaluation procedure. UE 104 may evaluate events, e.g., Event-1 or Event-2, in EEIs. UE 104 may trigger UEIBR based on the evaluation procedure. Event evaluation may include measuring the reference signal of the current beam in an EEI and comparing it against a threshold. The EEI may be referred to as a valid EEI if the measurement of the current beam is less than the threshold. For example, the measurement may be an L1-RSRP or SINR. In some embodiments, UE 104 may measure a reference signal of a new beam in an EEI and compare the measurement against that of the current beam. The EEI may be referred to as a valid EEI when the difference between the measurement of the new beam and that of the current beam is larger than a threshold.
[0108] UE 104 may trigger a UEIBR operation when the number of valid EEIs is larger than or equal to a threshold. In one example, UE 104 may count the number of valid EEIs until it reaches or exceeds the threshold. In another example, UE 104 may count the number of valid EEIs within an evaluation window. If the number of valid EEIs does not reach or exceed the threshold, UE 104 may reset the counter used for counting the number of valid EEIs.
[0109] The operation flow / algorithmic structure 800 may include, at 820, detecting a condition. UE 104 may detect a condition. In one example, the condition may be a configuration for a reference signal associated with the evaluation procedure. UE 104 may detect that a new configuration of a reference signal associated with the evaluation procedure is received. For example, UE 104 may receive a reconfiguration signal that reconfigures the reference signal of the new beam or the current beam’s reference signal.
[0110] In another example, the condition may be a change of the TCI associated with the evaluation procedure. For example, UE 104 may receive a configuration that changes the TCI state associated with the reference signal of the new beam or changes the TCI state associated with the reference signal of the current beam.
[0111] In another example, the condition may be receiving an uplink grant associated with the UEIBR operation. The receipt of the UL grant may indicate that the evaluation procedure has detected UEIBR-triggering events and has triggered UEIBR.
[0112] The operation flow / algorithmic structure 800 may include, at 830, resetting the evaluation procedure. UE 104 may reset the evaluation procedure. Resetting may include terminating the procedure and starting a new procedure. In one example, resetting may include resetting a counter of the evaluation procedure, e.g., a counter that counts the number of EEIs or a counter that counts the number of valid EEIs.
[0113] FIG. 9 illustrates an operation flow / algorithmic structure 900 in accordance with some embodiments. The operation flow / algorithmic structure 900 is related to UEIBR resource indication in Mode A. The operation flow / algorithmic structure 900 may be performed or implemented by a UE such as, for example, the UE 104 or UE 1200; or components thereof, for example, baseband processor circuitry 1204A.

The UL grant may be a DCI format, e.g., DCI format 0_1 or DCI format 0_2. UL grant may include a dedicated field associated with the resources for transmission of UEIBR operation, e.g., the first transmission or the second transmission. In some instances, the UL grant may include a field indicating resources for the UE-initiated beam report and the network-initiated beam report. In some examples, a CSI request codepoint is the field used to indicate the resources for the UE-initiated beam report or the NW-initiated beam report.
[0116] The operation flow / algorithmic structure 900 may include, at 930, determining the resource for a transmission occasion associated with the UEIBR operation. UE 104 may determine the resources for the UEIBR operation based on the UL grant. For example, the dedicated field in the UL grant may determine the resources for the second transmission of the UEIBR operation.
[0117] In another example, a field in the UL grant may determine resources for NW-initiated and UE-initiated beam reports. UE 104 may apply a mapping order rule to determine which report is mapped first. In one example, the UEIBR report is mapped first. In another example, the NW-initiated beam report is mapped first. In other examples, UE 104 may determine the mapping based on an ID associated with the reports. For example, UE 104 may determine the mapping order based on the report ID.

[0126] In some embodiments, UE 104 may multiplex the UCI only when there are UEIBR reports available. If a UEIBR operation is not triggered or no UEIBR report is available, UE 104 may not transmit a report on the resources associated with the UEIBR report (e.g., second transmission) . In some embodiments, UE 104 may multiplex the UCI even when there are no UEIBR reports available.

[0138] The processors 1204 may include processor circuitry such as, for example, baseband processor circuitry (BB) 1204A, central processor unit circuitry (CPU) 1204B, and graphics processor unit circuitry (GPU) 1204C. The processors 1204 may include any type of circuitry, or processor circuitry that executes or otherwise operates computer-executable instructions, such as program code, software modules, or functional processes from memory / storage 1212 to cause the UE 1200 to perform operations as described herein. The processors 1204 may also include interface circuitry 1204D to communicatively couple the processor circuitry with one or more other components of the UE 1200.
[0139] In some embodiments, the baseband processor circuitry 1204A may access a communication protocol stack 1236 in the memory / storage 1212 to communicate over a 3GPP-compatible network.

[0144] In the receive path, the RFEM may receive a radiated signal from an air interface via antenna 1226 and proceed to filter and amplify (with a low-noise amplifier) the signal. The signal may be provided to a receiver of the transceiver that down-converts the RF signal into a baseband signal that is provided to the baseband processor of the processors 1204.
[0145] In the transmit path, the transmitter of the transceiver up-converts the baseband signal received from the baseband processor and provides the RF signal to the RFEM. The RFEM may amplify the RF signal through a power amplifier prior to the signal being radiated across the air interface via the antenna 1226.
