AI Technical Summary
Existing wireless communication systems face challenges in determining the priority of Channel State Information (CSI) reports for User Equipment (UE) initiated beam reports, which can lead to inefficient resource allocation and increased overhead.
The proposed solution involves determining the priority of CSI reports for UE initiated beam reports by considering the priority of network initiated CSI reports, the events that trigger the UE initiated beam report, and the type of CSI reports. This is achieved through specific configurations and rules, such as configuring priorities via RRC signaling or using predetermined rules based on event types.
This approach allows for more efficient prioritization of CSI reports, reducing resource overhead and improving the overall performance of UE initiated beam reports in wireless communication systems.

[0038] Aspects of the present disclosure are described in the context of a wireless communications system.
[0039] Figure 1 illustrates an example of a wireless communications system 100 in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more NE 102, one or more UE 104, and a core network (CN) 106. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE (Long Term Evoluation) network or an LTE-Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a New Radio (NR) network, such as a 5G network, a 5G-Advanced (5G-A) network, or a 5G ultrawideband (5G-UWB) network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi) , IEEE 802.16 (WiMAX) , IEEE 802.20, etc. The wireless communications system 100 may support radio access technologies beyond 5G, for example, 6G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA) , frequency division multiple access (FDMA) , or code division multiple access (CDMA) , etc.
[0040] The one or more NE 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the NE 102 described herein may be or include or may be referred to as a network node, a base station, a network element, a network function, a network entity, a radio access network (RAN) , a NodeB, an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. An NE 102 and a UE 104 may communicate via a communication link 110, which may be a wireless or wired connection. For example, an NE 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface.
[0041] An NE 102 may provide a geographic coverage area for which the NE 102 may support services for one or more UEs 104 within the geographic coverage area. For example, an NE 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc. ) according to one or multiple radio access technologies. In some implementations, an NE 102 may be moveable, for example, a satellite associated with a non-terrestrial network (NTN) . In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies may overlap, but the different geographic coverage areas may be associated with different NE 102.
[0042] The one or more UE 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a remote unit, a mobile device, a wireless device, a remote device, a subscriber device, a transmitter device, a receiver device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an Internet-of-Things (IoT) device, an Internet-of-Everything (IoE) device, or machine-type communication (C) device, among other examples.
[0043] A UE 104 may be able to support wireless communication directly with other UEs 104 over a communication link. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link 114 may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.
[0044] An NE 102 may support communications with the CN 106, or with another NE 102, or both. For example, an NE 102 may interface with other NE 102 or the CN 106 through one or more backhaul links 116 (e.g., S1, N2, or another network interface) . The network entities 102 may communicate with each other over the backhaul links 116 (e.g., via an X2, Xn, or another network interface) . In some implementations, the NE 102 may communicate with each other directly. In some other implementations, the NE 102 may communicate with each other or indirectly (e.g., via the CN 106) . In some implementations, one or more NE 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC) . An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs) .
[0045] The CN 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The CN 106 may be an evolved packet core (EPC) , or a 5G core (5GC) , which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management functions (AMF) ) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as registration management, mobility management, connection management, access authentication / authorization etc. for the one or more UEs 104 served by the one or more NE 102 associated with the CN 106.
[0046] The CN 106 may communicate with a packet data network 108 over one or more backhaul links (e.g., via an S1, N2, or another network interface) . The packet data network 108 may include an application server 118. In some implementations, one or more UEs 104 may communicate with the application server 118. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the CN 106 via an NE 102. The CN 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server 118 using the established session (e.g., the established PDU session) . The PDU session may be an example of a logical connection between the UE 104 and the CN 106 (e.g., one or more network functions of the CN 106) .
[0047] In the wireless communications system 100, the NEs 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) ) to perform various operations (e.g., wireless communications) . In some implementations, the NEs 102 and the UEs 104 may support different resource structures. For example, the NEs 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the NEs 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the NEs 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures) . The NEs 102 and the UEs 104 may support various frame structures based on one or more numerologies.
[0048] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.
[0049] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames) . Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.
[0050] Additionally or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g., Orthogonal Frequency Division Multiplexing (OFDM) symbols) . In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing) , a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., μ=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.
[0051] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz –7.125 GHz) , FR2 (24.25 GHz –52.6 GHz) , FR3 (7.125 GHz –24.25 GHz) , FR4 (52.6 GHz –114.25 GHz) , FR4a or FR4-1 (52.6 GHz –71 GHz) , and FR5 (114.25 GHz –300 GHz) . In some implementations, the NEs 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the NEs 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data) . In some implementations, FR2 may be used by the NEs 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.
[0052] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies) . For example, FR1 may be associated with a first numerology (e.g., μ=0) , which includes 15 kHz subcarrier spacing; a second numerology (e.g., μ=1) , which includes 30 kHz subcarrier spacing; and a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies) . For example, FR2 may be associated with a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., μ=3) , which includes 120 kHz subcarrier spacing.

[0079] This disclosure relates to UE initiated (UEI) beam report (BR) .
[0080] Traditionally, beam report (e.g., CSI report with L1-RSRP reporting) was initiated at network side, e.g., by gNB. UEI BR is being specified in NR Release 19 for UL resource overhead reduction. For example, the UE shall only trigger beam report when the condition for some specified event (s) is satisfied to avoid frequent periodic or semi-persistent beam reporting.
[0081] The examples of specified events are as follows:
[0082] Event-1: Quality, such as layer 1 reference signal received power (L1-RSRP) , of the current beam is worse than a certain threshold.
[0083] Event-2: Quality, such as L1-RSRP, of at least one new beam becomes a threshold value better than the current beam.
[0084] Event-3: Quality, such as L1-RSRP, of at least one new beam becomes a threshold value better than the reference signal (RS) derived from the activated transmission configuration indication (TCI) state with the worst quality.
[0085] Event-4: Quality, such as L1-RSRP, of at least one new beam becomes a threshold value better than the RS derived from the activated TCI state with the best quality.
[0086] If the condition of an event (e.g., any of Event-1, Event-2, Event-3, Event-4) or any combination of the events is satisfied (step 0) , UE may initiate (or trigger) a beam report (i.e., UEI BR) . Two different modes are specified to support UEI BR.
[0087] Mode#A: dynamically scheduling uplink control information (UCI) by gNB. Three steps A1, A2 and A3 are included in UEI BR for mode#Ain addition to step 0, as shown in Figure 5.
[0088] Step A1: UE transmits, to gNB, a first Physical Uplink Control Channel (PUCCH) to request a resource for a second UL channel to carry UL beam report. A scheduling request (SR) for UEI beam report (referred as UEI beam report SR hereinafter) is carried on the first PUCCH.
[0089] Step A2: gNB sends, to UE, a UL grant (e.g., a resource for a second UL channel) for UEI BR where the UL grant is contained in a downlink control information (DCI) , in response to receiving the UEI BR SR. UE detects the DCI.
[0090] Step A3: UE transmits, to gNB, the UEI BR in the second UL channel. Note that although either PUSCH or PUCCH can be the second UL channel, Figure 5 only shows PUSCH as the example of the second UL channel in step A3.
[0091] Mode#B: UCI in pre-configured resource (s) for the second UL channel. Two steps B1 and B2 are included in UEI BR for mode#B in addition to step 0, as shown in Figure 6.
[0092] Step B1: UE transmits, to gNB, a first PUCCH (with one or multiple bits) carrying a UEI beam report notification that notifies gNB of UEI BR to be carried on a second UL channel.
[0093] Step B2: UE transmits, to gNB, the UEI BR in the second UL channel (e.g., PUSCH or PUCCH) . Note that although either PUSCH or PUCCH can be the second UL channel, Figure 6 only shows PUSCH as the example of the second UL channel in step B2.
[0094] Note that the notification in step B1 is in a separate reporting instance from the UEI BR in step B2. It means that step B1 and step B2 are performed at different time instances with different resources.
[0095] This disclosure targets the priority of CSI reports, especially, of CSI reports for UE initiated beam report.
[0096] Before describing the invention, a brief summary of conventional priority rules for CSI reports is described.
[0097] Traditionally, CSI reports include CSI reports for LTM (L1 / L2 Triggered Mobility) (e.g., configured with LTM-CSI-ReportConfig IE) and CSI reports for non-LTM (i.e., legacy CSI reports) (e.g., configured with CSI-ReportConfig IE) .
[0098] CSI reports are associated with a priority value PriiCSI (y, k, c, s) =2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s ( [Equation 1] ) , where
[0099] y=0 for aperiodic (AP) CSI reports to be carried on PUSCH, y=1 for semi-persistent (SP) CSI reports to be carried on PUSCH, y=2 for semi-persistent CSI reports to be carried on PUCCH, and y=3 for periodic CSI reports to be carried on PUCCH;
[0100] k=0 for CSI reports carrying L1-RSRP (layer 1 reference signal receiving power) or L1-SINR (layer 1 signal to interference noise ratio) , and k=1 for CSI reports not carrying L1-RSRP or L1-SINR;
[0101] c is the serving cell index and Ncells is the value of the maximum number of serving cells (e.g., higher layer parameter maxNrofServingCells) , and for a CSI report configured with LTM-CSI-ReportConfig, c is the serving cell index value where the report configuration is configured;
[0102] s is the report configuration index (e.g., reportConfigID) , and Ms is the value of the maximum number of CSI report configurations (e.g., higher layer parameter maxNrofCSI-ReportConfigurations) , and for a CSI report configured with LTM-CSI-ReportConfig, s is the LTM CSI report configuration index (e.g., LTM-CSI-ReportConfigID) and Ms is the value of the maximum number of LTM CSI report configurations (e.g., higher layer parameter maxNrofLTM-CSI-ReportConfigurations) .
[0103] A first CSI report is said to have a higher priority than a second CSI report if the PriiCSI (y, k, c, s) value associated with the first CSI report is lower than the PriiCSI (y, k, c, s) value associated with the second CSI report.
[0104] Two CSI reports are said to collide if the time occupancy of the physical channels (e.g., PUSCH or PUCCH) scheduled to carry the CSI reports overlap in at least one OFDM symbol and are transmitted on the same carrier. When a UE is configured to transmit two collided CSI reports, if y values are different between the two CSI reports, the CSI report with higher PriiCSI (y, k, c, s) value shall not be sent by the UE except for the case when one of the y value is 2 and the other y value is 3; otherwise, the two CSI reports are multiplexed or either is dropped based on the priority values.
[0105] In NR Release 19, there may be three types of CSI reports. A first type is CSI report for LTM (configured by LTM-CSI-ReportConfig) . A second type is CSI report for non-LTM without AI operation (configured by CSI-ReportConfig) , which can be referred to as legacy CSI report. A third type is CSI report for non-LTM with AI operation (which may be configured by AI-CSI-ReportConfig) . Each type of the CSI report may include network (e.g., gNB) initiated CSI report and UE initiated CSI report. All types of CSI reports can be configured for a UE in a BWP of a serving cell. For a first example, CSI report for LTM and CSI report for non-LTM without AI operation can be configured for the UE in a BWP of a serving cell. For a second example, CSI report for LTM, CSI report for non-LTM without AI operation and CSI report for non-LTM with AI operation can be configured for the UE in a BWP of a serving cell.
[0106] As described above, UE initiated CSI report can be triggered by any or any combination of events (e.g., Event-1, Event-2, Event-3, Event-4) .
[0107] It thus can be seen that the priority of CSI report for UE initiated beam report can be determined by at least one of the following factors: (1) a priority of the network initiated CSI reports, i.e., the priority between the CSI reports for UE initiated beam report and the network initiated CSI reports; (2) events that trigger the UE initiated beam report; (3) the type of the CSI reports.
[0108] A first embodiment relates to determining the priority of the CSI reports for UE initiated beam report by considering a priority of the network initiated CSI reports, i.e., the priority between the CSI reports for UE initiated beam report and the network initiated CSI reports.
[0109] As can be seen from the summary of the conventional priority rules for CSI reports (e.g., different values of the parameter y) , network initiated CSI reports include (from higher priority to lower priority) : AP CSI reports to be carried on PUSCH (y=0) , SP CSI reports to be carried on PUSCH (y=1) , SP CSI reports to be carried on PUCCH (y=2) , and periodic CSI reports to be carried on PUCCH (y=3) .
[0110] The first embodiment proposes that the priority of a CSI report for UE initiated beam report can be higher than or the same as any of the priorities of different network initiated CSI reports. Incidentally, the priority order among the network initiated CSI reports remains unchanged. As a whole, there are eight options for the priority of the CSI reports for UE initiated beam report:
[0111] Option#1: the same as the priority of AP CSI reports to be carried on PUSCH.
[0112] Option#2: higher than the priority of AP CSI reports to be carried on PUSCH.
[0113] Option#3: the same as the priority of SP CSI reports to be carried on PUSCH.
[0114] Option#4: higher than the priority of SP CSI reports to be carried on PUSCH and lower than the priority of AP CSI reports to be carried on PUSCH.
[0115] Option#5: the same as the priority of SP CSI reports to be carried on PUCCH.
[0116] Option#6: higher than the priority of SP CSI reports to be carried on PUCCH and lower than the priority of SP CSI reports to be carried on PUSCH.
[0117] Option#7: the same as the priority of periodic CSI reports to be carried on PUCCH.
[0118] Option#8: higher than the priority of periodic CSI reports to be carried on PUCCH and lower than the priority of SP CSI reports to be carried on PUCCH.
[0119] Depending on mode#A or mode#B being configured and PUSCH or PUCCH carrying the CSI report for UEI BR, the CSI reports for UEI BR can have four cases.
[0120] Case#A1: mode#Ais configured and the CSI report for UEI BR is carried on PUSCH scheduled by a DCI carried on PDCCH (Physical Downlink Control Channel) .
[0121] Case#A2: mode#Ais configured and the CSI report for UEI BR is carried on PUCCH scheduled by a DCI carried on PDCCH.
[0122] Case#B1: mode#B is configured and the CSI report for UEI BR is carried on CG-PUSCH (configured grant PUSCH) .
[0123] Case#B2: mode#B is configured and the CSI report for UEI BR is carried on PUCCH.
[0124] The priority of the CSI reports for UE initiated beam report for each of Case#A1, Case#A2, Case#B1 and Case#B2 is proposed as follows.
[0125] For Case#A1, Option#1 (with the priority the same as the priority of AP CSI reports to be carried on PUSCH) or Option#2 (with the priority higher than the priority of AP CSI reports to be carried on PUSCH) can be determined.
[0126] For example, in Option#1 for Case#A1, the CSI reports are associated with a priority value PriiCSI (y, k, c, s) =2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s, where y=0 for AP CSI reports to be carried on PUSCH and for CSI reports for UEI BR carried on PUSCH with mode#A; y=1 for SP CSI reports to be carried on PUSCH, y=2 for SP CSI reports to be carried on PUCCH, and y=3 for periodic CSI reports to be carried on PUCCH; the parameters k, c, Ncells, s, Ms and their values are the same as in [Equation 1] .
[0127] For example, in Option#2 for Case#A1, the CSI reports are associated with a priority value PriiCSI (z, y, k, c, s) =8·Ncells·Ms·z+2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s, where z=0 for CSI reports for UEI BR carried on PUSCH with mode#A, z=1 for network initiated CSI reports (e.g., CSI report configured with CSI-ReportConfig for periodic, semi-persistent and aperiodic reports) ; y=0 for AP CSI reports to be carried on PUSCH; y=1 for SP CSI reports to be carried on PUSCH, y=2 for SP CSI reports to be carried on PUCCH, and y=3 for periodic CSI reports to be carried on PUCCH; the parameters k, c, Ncells, s, Ms and their values are the same as in [Equation 1] .

[0150] A second embodiment relates to determining the priority of the CSI reports for UE initiated beam report by considering events that trigger the UE initiated beam report.
[0151] Variable events (e.g., event-1, event-2, event-3, event-4) may be specified for different purpose. More than one event may be configured for a UE in a BWP of a serving cell by a dedicated RRC (Radio Resource Control) configuration. For example, a dedicated RRC information element (e.g., UE-Initiated-BeamReportConfig IE) may be configured for UE initiated beam report with different events. In this condition, CSI reports for UE initiated beam report triggered by different events may be determined to be reported in a same slot while the UE can only report one CSI report for one beam in the same slot. A priority is needed for the UE to determine to report the CSI report for UE initiated beam report triggered by which events. Different options are proposed in the second embodiment.
[0152] Option#21: The priority is configured by the RRC signaling. For example, a priority is configured by RRC signaling within UE-Initiated-BeamReportConfig IE. For example, if event-1, event-2 and event-3 are configured for the UE in a BWP of a serving cell, the priority “event-1 > event-2 > event-3” may be configured by RRC signaling within UE-Initiated-BeamReportConfig IE. It means that the priority of the CSI report for UEI BR triggered by event-1 is higher than the priority of the CSI report for UEI BR triggered by event-2; and the priority of the CSI report for UEI BR triggered by event-2 is higher than the priority of the CSI report for UEI BR triggered by event-3.
[0153] Option#22: The priority is determined by UE implementation. For example, if the conditions for two or more events are satisfied in a same slot but the UE can only trigger the beam report corresponding to one event, the UE determines to report the CSI report for UEI BR triggered by which event based on UE implementation. In this case, event related information is needed to be indicated to let the network (e.g., gNB) know which event triggers the beam report. For example, an event ID is included in the reported CSI report for UEI BR to let the network (e.g., gNB) know the event (e.g., event-1, event-2, event-3, or event-4) that triggers the CSI report for UEI BR.
[0154] Option#23: The priority is determined by a predetermined rule, e.g., a specified priority rule. For example, the predetermined rule may be event-1 > event-2 > event-3 >event-4. It means that the priority of the CSI report for UEI BR triggered by event-1 is higher than the priority of the CSI report for UEI BR triggered by event-2; the priority of the CSI report for UEI BR triggered by event-2 is higher than the priority of the CSI report for UEI BR triggered by event-3; and the priority of the CSI report for UEI BR triggered by event-3 is higher than the priority of the CSI report for UEI BR triggered by event-4. For another example, the predetermined rule may be event-1 > event-2 = event-4 > event-3. It means that the priority of the priority of the CSI report for UEI BR triggered by event-1 is higher than the priority of the CSI report for UEI BR triggered by event-2 or event-4; the priority of the CSI report for UEI BR triggered by event-2 is the same as the priority of the CSI report for UEI BR triggered by event-4; and the priority of the CSI report for UEI BR triggered by event-2 or event-4 is higher than the priority of the CSI report for UEI BR triggered by event-3.
[0155] A third embodiment relates to determining the priority of the CSI reports for UE initiated beam report by considering the type of the CSI report.
[0156] As mentioned earlier, there are three types of CSI reports in NR Release 19: CSI report for LTM; CSI report for non-LTM without AI operation; and CSI report for non-LTM with AI operation.
[0157] According to the third embodiment, when CSI report for LTM and CSI report for non-LTM without AI operation are configured for the UE in a BWP of a serving cell, the priority of any CSI report for LTM (e.g., for UEI BR) is higher than the priority of all CSI reports for non-LTM without AI operation (e.g., for UEI BR) . It means that the PriiCSI (y, k, c, s) value is not considered in the priority of different types of CSI reports. In particular, the priority of the CSI report for LTM is higher than the priority of CSI reports for non-LTM without AI operation irrespective of PriiCSI (y, k, c, s) value.
[0158] When CSI report for LTM, CSI report for non-LTM without AI operation and CSI report for non-LTM with AI operation are configured for the UE in a BWP of a serving cell, the priority of any CSI report for LTM is higher than the priority of all CSI reports for non-LTM without AI operation (e.g., for UEI BR) ; and the priority of any CSI report for non-LTM without AI operation (e.g., for UEI BR) is higher than the priority of all CSI reports for non-LTM with AI operation. It means that the PriiCSI (y, k, c, s) value is not considered in the priority of different types of CSI reports. In particular, the priority of the CSI report for LTM is higher than the priority of CSI reports for non-LTM without AI operation irrespective of PriiCSI (y, k, c, s) value; and the priority of the CSI report for non-LTM without AI operation is higher than the priority of CSI reports for non-LTM with AI operation irrespective of PriiCSI (y, k, c, s) value.
[0159] A fourth embodiment relates to determining the priority of the CSI reports for UE initiated beam report by considering two or more of a priority of the network initiated CSI reports, events that trigger the UE initiated beam report, and the type of the CSI report.
[0160] The first embodiment, which describes determining the priority of the CSI reports for UE initiated beam report by considering a priority of the network initiated CSI reports, assumes that the events that trigger the UE initiated beam report are not considered in determining the priority of the CSI reports for UE initiated beam report or only one event is configured in the BWP of a serving cell for a CSI report type.
[0161] A first sub-embodiment of the fourth embodiment relates to determining the priority of the CSI reports for UE initiated beam report by considering a priority of the network initiated CSI reports, and events that trigger the UE initiated beam report.
[0162] For a first example, for Case#A1 (i.e., mode#Ais configured and the CSI report for UEI BR is carried on PUSCH) , it is proposed that the priority order (from higher to lower) is: CSI reports for UE initiated beam report carried on PUSCH with mode#Atriggered by event-1 > AP CSI reports to be carried on PUSCH > CSI reports for UE initiated beam report carried on PUSCH with mode#Atriggered by event-2 or event-4 > SP CSI reports to be carried on PUSCH > CSI reports for UE initiated beam report carried on PUSCH with mode#Atriggered by event-3 > SP CSI reports to be carried on PUCCH >periodic CSI reports to be carried on PUCCH.
[0163] For a second example, for Case#A2 (i.e., mode#Ais configured and the CSI report for UEI BR is carried on PUCCH) , it is proposed that the priority order (from higher to lower) is: AP CSI reports to be carried on PUSCH > CSI reports for UE initiated beam report carried on PUCCH with mode#Atriggered by event-1 > SP CSI reports to be carried on PUSCH > CSI reports for UE initiated beam report carried on PUCCH with mode#Atriggered by event-2 or event-4 > SP CSI reports to be carried on PUCCH > CSI reports for UE initiated beam report carried on PUCCH with mode#Atriggered by event-3 > periodic CSI reports to be carried on PUCCH.
[0164] For a third example, for Case#B1 (i.e., mode#B is configured and the CSI report for UEI BR is carried on PUSCH) , it is proposed that the priority order (from higher to lower) is: AP CSI reports to be carried on PUSCH > CSI reports for UE initiated beam report carried on PUSCH with mode#B triggered by event-1 > SP CSI reports to be carried on PUSCH > CSI reports for UE initiated beam report carried on PUSCH with mode#B triggered by event-2 or event-4 > SP CSI reports to be carried on PUCCH > CSI reports for UE initiated beam report carried on PUSCH with mode#B triggered by event-3 > periodic CSI reports to be carried on PUCCH.
[0165] For a fourth example, for Case#B2 (i.e., mode#B is configured and the CSI report for UEI BR is carried on PUCCH) , it is proposed that the priority order (from higher to lower) is: AP CSI reports to be carried on PUSCH > SP CSI reports to be carried on PUSCH > SP CSI reports to be carried on PUCCH > CSI reports for UE initiated beam report carried on PUCCH with mode#B triggered by event-1 > CSI reports for UE initiated beam report carried on PUCCH with mode#B triggered by event-2 or event-4 > CSI reports for UE initiated beam report carried on PUCCH with mode#B triggered by event-3 >periodic CSI reports to be carried on PUCCH.
[0166] A second sub-embodiment of the fourth embodiment relates to determining the priority of the CSI reports for UE initiated beam report by considering a priority of the network initiated CSI reports, and the type of the CSI report.
[0167] For example, it is proposed that the priority order (from higher to lower) is: CSI reports for LTM for UE initiated beam report carried on PUSCH > AP CSI reports for LTM to be carried on PUSCH > SP CSI reports for LTM to be carried on PUSCH > CSI reports for LTM for UE initiated beam report carried on PUCCH > SP CSI reports for LTM to be carried on PUCCH > periodic CSI reports for LTM to be carried on PUCCH > CSI reports for non-LTM without AI operation for UE initiated beam report carried on PUSCH > AP CSI reports for non-LTM without AI operation to be carried on PUSCH > SP CSI reports for non-LTM without AI operation to be carried on PUSCH > CSI reports for non-LTM without AI operation for UE initiated beam report carried on PUCCH > SP CSI reports for non-LTM without AI operation to be carried on PUCCH > periodic CSI reports for non-LTM without AI operation to be carried on PUCCH > CSI reports for non-LTM with AI operation for UE initiated beam report carried on PUSCH > AP CSI reports for non-LTM with AI operation to be carried on PUSCH > SP CSI reports for non-LTM with AI operation to be carried on PUSCH > CSI reports for non-LTM with AI operation for UE initiated beam report carried on PUCCH > SP CSI reports for non-LTM with AI operation to be carried on PUCCH > periodic CSI reports for non-LTM with AI operation to be carried on PUCCH.
[0168] Any CSI report for LTM has a higher priority than all CSI reports for non-LTM without AI operation irrespective of PriiCSI (y, k, c, s) value; and any CSI report for non-LTM without AI operation has a higher priority than all CSI reports for non-LTM with AI operation irrespective of PriiCSI (y, k, c, s) value. On the other hand, within each type of CSI report (CSI report for LTM, CSI report for non-LTM without AI operation, CSI report for non-LTM with AI operation) , the priority can be separately determined.
[0169] To support this example, the following priority value equation is proposed:
[0170] PriiCSI (z, y, k, c, s) =12·Ncells·Ms·z+2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s, where
[0171] z=0 for CSI reports for LTM, z=1 for CSI reports for non-LTM without AI operation, and z=2 for CSI reports for non-LTM with AI operation;
[0172] y=0 for CSI reports for UE initiated beam report carried on PUSCH, y=1 for AP CSI reports to be carried on PUSCH, y=2 for SP CSI reports to be carried on PUSCH, y=3 for CSI reports for UE initiated beam report carried on PUCCH, y=4 for SP CSI reports to be carried on PUCCH, and y=5 for periodic CSI reports to be carried on PUCCH;
[0173] k=0 for CSI reports carrying L1-RSRP or L1-SINR and k=1 for CSI reports not carrying L1-RSRP or L1-SINR;
[0174] c is the serving cell index and Ncells is the value of the higher layer parameter maxNrofServingCells;
[0175] s is the report configuration index (e.g., reportConfigID) ;
[0176] where is the maximum number of configurations for the CSI report for LTM; is the maximum number of configurations for CSI report for non-LTM without AI operation; and is the maximum number of configurations for CSI report for non-LTM with AI operation.
[0177] In summary, the CSI reports for LTM have a higher priority than any CSI report for non-LTM without AI operation irrespective of PriiCSI (y, k, c, s) value; and all CSI report for non-LTM without AI operation have a higher priority than any CSI report for non-LTM with AI operation irrespective of PriiCSI (y, k, c, s) value. Within each type of CSI report (CSI report for LTM, CSI report for non-LTM without AI operation, CSI report for non-LTM with AI operation) , a first CSI report is said to have a higher priority than a second CSI report if the PriiCSI (z, y, k, c, s) value associated with the first CSI report is lower than the PriiCSI (z, y, k, c, s) value associated with the second CSI report.
[0178] A third sub-embodiment of the fourth embodiment relates to determining the priority of the CSI reports for UE initiated beam report by considering events that trigger the UE initiated beam report, and the type of the CSI report.
[0179] The third sub-embodiment of the fourth embodiment can be regarded as a combination of the second embodiment and the third embodiment.
[0180] In particular, any CSI report for LTM has a higher priority than all CSI reports for non-LTM without AI operation irrespective of PriiCSI (y, k, c, s) value; and any CSI report for non-LTM without AI operation has a higher priority than all CSI reports for non-LTM with AI operation irrespective of PriiCSI (y, k, c, s) value; and within each type of CSI report (CSI report for LTM, CSI report for non-LTM without AI operation, CSI report for non-LTM with AI operation) , the priority is determined by considering different events that trigger the UE initiated beam report (e.g., by the priority order described in any of Option#21 or Option#22 or Option#23 of the second embodiment) .
[0181] A fourth sub-embodiment of the fourth embodiment relates to determining the priority of the CSI reports for UE initiated beam report by considering a priority of the network initiated CSI reports, events that trigger the UE initiated beam report, and the type of the CSI report.
[0182] The fourth sub-embodiment of the fourth embodiment can be regarded as a combination of the first sub-embodiment of the fourth embodiment and the third embodiment (or a combination of the first embodiment, the second embodiment and the third embodiment) .
[0183] In particular, any CSI report for LTM has a higher priority than all CSI reports for non-LTM without AI operation irrespective of PriiCSI (y, k, c, s) value; and any CSI report for non-LTM without AI operation has a higher priority than all CSI reports for non-LTM with AI operation irrespective of PriiCSI (y, k, c, s) value; and within each type of CSI report (CSI report for LTM, CSI report for non-LTM without AI operation, CSI report for non-LTM with AI operation) , the priority is determined by considering a priority of the network initiated CSI reports, and events that trigger the UE initiated beam report (e.g., according to the priority order described in any of the first example, the second example, the third example and the fourth example in the first sub-embodiment of the fourth embodiment) .
[0184] The above (first, second, third and fourth) embodiments describe the invention mainly from UE’s point of view. The base station (e.g., gNB) can perform the same determination of the priority with the same manner as the UE. The only differences are the option#21 in the second embodiment, in which the priority is configured by RRC signaling from the base station, and the option#22 in the second embodiment, in which the priority is determined by UE implementation. It means that, for option#21, the priority is always configured by RRC signaling from the base station, while for option#22, the priority is always determined by UE implementation (and an event ID is included in the reported CSI report to the base station) . That is, when the base station receives the CSI report including an event ID, the base station knows the event that triggers the CSI report.
[0185] Figure 7 illustrates a flowchart of a method 700 in accordance with aspects of the present disclosure. The operations of the method may be implemented by a UE as described herein. In some implementations, the UE may execute a set of instructions to control the function elements of the UE to perform the described functions.

[0187] In some embodiment, the priority of CSI reports for UE initiated beam report is determined by considering a priority of network initiated CSI reports.
[0188] When mode#Ais configured for the UE initiated beam report and the CSI report for UE initiated beam report is carried on PUSCH, the priority of the CSI reports for UE initiated beam report is the same as the priority of AP CSI reports to be carried on PUSCH, or higher than the priority of AP CSI reports to be carried on PUSCH.
