[Modes for carrying out the invention]

[0014] Referring to Figure 1, this figure is a block diagram showing one possible, non-limiting example in which this embodiment may be implemented. A user device (UE) 110, a radio access network (RAN) node 170, and a network element 190 are shown. In the example of Figure 1, the user device (UE) 110 communicates wirelessly with the radio network 100. The UE is a radio device that can access the radio network 100. The UE 110 includes one or more processors 120, one or more memories 125, and one or more transceivers 130, which are interconnected via one or more buses 127. Each of the transceivers 130 includes a receiver Rx132 and a transmitter Tx133. The one or more buses 127 may be an address bus, a data bus, or a control bus, and may include any interconnection mechanism, such as a series of wires on a motherboard or integrated circuit, or optical fibers or other optical communication equipment. One or more transceivers 130 are connected to one or more antennas 128. One or more memories 125 contain computer program code 123. The UE110 comprises a module 140, which may include either or both of parts 140-1 and / or 140-2, and may be implemented in various ways. Module 140 may be implemented in hardware, for example, as module 140-1, which may be implemented as part of one or more processors 120. Module 140-1 may be implemented as an integrated circuit or via other hardware such as a programmable gate array. In another example, module 140 may be implemented as module 140-2, which is implemented as computer program code 123 and executed by one or more processors 120. For example, one or more memories 125 and computer program code 123, together with one or more processors 120, are configured to cause user equipment 110 to perform one or more operations described herein. The UE110 communicates with the RAN node 170 via a radio link 111.

[0015] In this example, RAN node 170 is a base station for radio equipment such as UE 110 to access the radio network 100. RAN node 170 may be, for example, a base station for 5G, also known as New Radio (NR). In 5G, RAN node 170 can be an NG-RAN node, which is defined as either a gNB or an ng-eNB. A gNB is a node that provides termination of the NR user plane and control plane protocols to the UE and is connected to the 5GC (e.g., network element 190) via an NG interface (e.g., connection 131). An ng-eNB is a node that provides termination of the E-UTRA user plane and control plane protocols to the UE and is connected to the 5GC via an NG interface (e.g., connection 131). An NG-RAN node may contain multiple gNBs, which may include a central unit (CU) (gNB-CU) 196 and distributed units (DU) (gNB-DU). DU 195 is shown in this figure. DU 195 may contain a radio unit (RU) or be controlled by connecting to a RU. gNB-CU196 is a logical node that hosts the radio resource control (RRC), SDAP, and PDCP protocols of the gNB, or the RRC and PDCP protocols of the en-gNB, which control the operation of one or more gNB-DUs. gNB-CU196 terminates the F1 interface connected to gNB-DU195. The F1 interface is shown as reference numeral 198, which also indicates links between remote and centralized elements of RAN node 170 (e.g., between gNB-CU196 and gNB-DU195). gNB-DU195 is a logical node that hosts the RLC layer, MAC layer, and PHY layer of the gNB or en-gNB, and its operation is partially controlled by gNB-CU196. A single gNB-CU196 supports one or more cells. A single cell may be supported by one gNB-DU195, or it may be supported / shared by multiple DUs under RAN sharing. The gNB-DU195 terminates the F1 interface 198, which is connected to the gNB-CU196.Note that DU195 is considered to include transceiver 160. For example, it is included as part of RU, but in some cases transceiver 160 may exist as part of a separate RU, for example, under the control of DU195 and connected to DU195. RAN node 170 may be an eNB (Evolved NodeB) base station for LTE (Long-Term Evolution), or other appropriate base station or node.

[0016] RAN node 170 includes one or more processors 152, one or more memories 155, one or more network interfaces (N / WI / F) 161, and one or more transceivers 160, which are interconnected via one or more buses 157. Each of the one or more transceivers 160 includes a receiver Rx162 and a transmitter Tx163. One or more transceivers 160 are connected to one or more antennas 158. One or more memories 155 contain computer program code 153. CU 196 may include a processor 152, one or more memories 155, and a network interface 161. Note that DU 195 may also include its own memory, processor, and other hardware, but these are not shown.

[0017] RAN node 170 includes module 150, which may include either or both of part 150-1 and / or part 150-2, and can be implemented in various ways. Module 150 may be implemented in hardware, for example, as module 150-1 implemented as part of one or more processors 152. Module 150-1 may also be implemented as an integrated circuit or via other hardware such as a programmable gate array. In another example, module 150 may be implemented as module 150-2, which is implemented as computer program code 153 and executed by one or more processors 152. For example, one or more memories 155 and computer program code 153, together with one or more processors 152, are configured to cause RAN node 170 to perform one or more operations described herein. Note that the functionality of module 150 may be distributed between DU195 and CU196, for example, or implemented only in DU195.

[0018] One or more network interfaces 161 communicate over the network via links 176 and 131. Two or more gNBs 170 may communicate using, for example, link 176. Link 176 may be wired, wireless, or both, and may implement, for example, an Xn interface for 5G, an X2 interface for LTE, or an interface suitable for other standards.

[0019] One or more buses 157 may be an address bus, a data bus, or a control bus, and may include a series of wirings on a motherboard or integrated circuit, or any interconnection mechanism such as an optical fiber or other optical communication device, a wireless channel, etc. For example, one or more transceivers 160 may be implemented as a remote radio head (RRH) 195 for LTE or a distributed unit (DU) 195 for gNB implementation in 5G. In this case, other elements of the RAN node 170 may be physically located at different places from the RRH / DU 195. Also, one or more buses 157 may be implemented, for example, as part of an optical fiber cable or other suitable network connection, and can connect other elements of the RAN node 170 (e.g., a central unit (CU), gNB-CU 196) to the RRH / DU 195. Reference numeral 198 indicates these suitable network links.

[0020] The RAN node / gNB may include one or more TRPs to which the methods described herein can be applied. FIG. 1 shows that the RAN node 170 includes two TRPs, namely, TRP51 and TRP52. The RAN node 170 may host or include other TRPs not shown in FIG. 1.

[0021] The relay node in NR is called an integrated access backhaul (IAB) node. The mobile termination part of the IAB node enables a backhaul (parent link) connection. In other words, the mobile termination part is a component that performs UE functions. The distributed unit part of the IAB node enables a so-called access link (child link) connection (specifically, a connection for an access link UE and also a backhaul connection for another IAB node in the case of a multi-hop IAB). In other words, the distributed unit part performs specific base station functions. The IAB scenario may follow a so-called split architecture, in which case the central unit hosts upper layer protocols for the UE and terminates the control plane and user plane interfaces for the 5G core network.

[0022] In this specification, "cell" is described as performing a function, but it is clear that the equipment comprising a cell can perform that function. A cell constitutes part of a base station. That is, there can be multiple cells in each base station. For example, if there are three cells for a single carrier frequency and associated bandwidth, and each cell covers one-third of a 360-degree area, the coverage area of ​​a single base station will be roughly elliptical or circular. Furthermore, each cell corresponds to a single carrier wave, and a base station can use multiple carrier waves. Therefore, if there are three 120-degree cells for each carrier wave, and there are two carrier waves, the base station will have a total of six cells.

[0023] The wireless network 100 has a network element 190 that includes core network functions and provides a connection to an external network such as a telephone network or a data communication network (e.g., the Internet) via a link 181. Such core network functions in 5G include a Location Management Function (LMF), an Access Mobility Management Function (AMF), a User Plane Function (UPF), a Session Management Function (SMF), etc. Core network functions in LTE may include an MME (Mobility Management Entity) / SGW (Service Gateway) function. Also, the core network functions may include a SON (Self-Organizing / Optimizing Network) function. These are merely examples of functions that the network element 190 may support, and it should be noted that it is possible to support functions for both 5G and LTE. The RAN node 170 is connected to the network element 190 via a link 131. The link 131 is implemented as, for example, an NG interface for 5G, an S1 interface for LTE, or an appropriate interface for other standards. The network element 190 includes one or more processors 175, one or more memories 171, and one or more network interfaces (N / W I / F) 180, which are interconnected via one or more buses 185. The one or more memories 171 include computer program code 173. The computer program code 173 may include SON and / or MRO functions 172.

[0024] The wireless network 100 can implement network virtualization. This is the process of integrating hardware and software network resources and network functions into a single software-based management entity, i.e., a virtual network. Network virtualization includes platform virtualization and is often combined with resource virtualization. Network virtualization is classified into external (integrating multiple networks or parts of networks into a virtual unit) and internal (providing network-like functions to a software container on a single system). It should be noted that the virtualized entities generated by network virtualization are still implemented using hardware such as processors 152 and 175 and memory 155 and 171 at some level, and that these virtualized entities produce technical effects.

[0025] Computer-readable memories 125, 155, and 171 are of any type suitable for the local technical environment and can be implemented using any suitable data storage technology, such as semiconductor-based memory devices, flash® memory, magnetic memory devices and systems, optical memory devices and systems, non-temporary memory, temporary memory, fixed memory, and removable memory. Computer-readable memories 125, 155, and 171 can be means for performing storage functions. Processors 120, 152, and 175 are of any type suitable for the local technical environment and, as non-limiting examples, may include one or more general-purpose computers, dedicated computers, microprocessors, digital signal processors (DSPs), and processors based on multi-core processor architectures. Processors 120, 152, and 175 can be means for performing functions to control the UE 110, the RAN node 170, the network element 190, and other functions described herein.

[0026] Generally, various embodiments of the user device 110 include, but are not limited to, mobile phones such as smartphones, tablets, personal digital assistants (PDAs) with wireless communication capabilities, portable computers with wireless communication capabilities, image capture devices such as digital cameras with wireless communication capabilities, game consoles with wireless communication capabilities, music storage and playback devices with wireless communication capabilities, internet devices that enable wireless internet access and browsing, tablets with wireless communication capabilities, head-mounted displays that realize virtual reality / augmented reality / mixed reality, and portable units and terminals that combine these functions. The UE 110 may also be a vehicle such as an automobile, or a UE mounted on a vehicle, a UAV such as a drone, or a UE mounted on a UAV. The user device 110 may be a terminal device such as a mobile phone, mobile device, or sensor device, and this terminal device may be a device used by the user or a device not used by the user.

[0027] UE110, RAN node 170, and / or network element 190 (as well as associated memory, computer program code, modules) may be configured (for example, as part thereof) to implement the methods described herein, namely, methods that include facilitating procedures related to UE-centric BM and / or CSI. Thus, the computer program code 123, module 140-1, module 140-2, and other elements / functions of UE110 shown in Figure 1 may implement user equipment-related embodiments in the examples described herein. Similarly, the computer program code 153, module 150-1, module 150-2, and other elements / features of RAN node 170 shown in Figure 1 may implement gNB / TRP-related embodiments in the embodiments described herein. The computer program code 173 and other elements / features of network element 190 shown in Figure 1 may be configured to implement embodiments related to network elements in the embodiments described herein.

[0028] Having presented the appropriate but not limiting technical background for implementing this embodiment, we will now describe the embodiment in more detail.

[0029] The embodiments described herein relate to the 3GPP® New Radio (NR) physical layer development. NR is also known as the fifth-generation (5G) radio system developed by 3GPP®. More specifically, the methods described herein focus on procedures related to beam management initiated by the UE, which is a promising topic of consideration in MIMO for Rel-19. While the focus is on NR Rel-19, the proposed functionality may be considered as input to future 6G research projects. 6G seeks to introduce a new carrier frequency band of 7–20 GHz, and its operation can be seen as a mixture of FR1 (0–6 GHz) and FR2 (24–70 GHz). That is, in the context of the embodiments described herein, it is likely that in FR3, the UE operates using antenna arrays and analog beamforming components, and beam management procedures for beam alignment of the gNB and UE are implemented.

[0030] Beam management defines a set of functions that help the UE configure the RX beam and TX beam for downlink reception and uplink transmission, respectively. These functions can generally be categorized into the following four groups:

[0031] 1. Beam Instructions: The UE110 assists in properly setting the RX beam and TX beam for DL ​​reception and UL transmission, respectively.

[0032] 2. Beam acquisition, measurement, and reporting: Procedures for providing gNB with information on feasible DL and UL beams to the UE.

[0033] 3. Beam recovery: Used for rapid link reconstruction in response to sudden shielding, i.e., for rapid realignment of the gNB and UE beams.

[0034] 4. Beam tracking and refinement: A series of procedures to refine the beams on the gNB and UE sides.

[0035] With regard to downlink beam management, particularly beam acquisition, measurement, and reporting (item 2 above), the following beam management procedures are supported within one or more TRPs (e.g., TRP51 and / or TRP52) of the serving cell (also shown in Figure 2).

[0036] P-1 (Procedure 1): This procedure enables UE measurements for different TRP transmit beams (e.g., TRP transmit beams 1, 2, 3, and 4 shown in P-1) and is used to assist in the selection of TRP transmit beams and / or one or more UE receive beams. With respect to beamforming in TRP51, the measurement and selection typically involve intra- and inter-TRP Tx beam sweeps from different sets of beams (e.g., TRP Tx beams 1, 2, 3, and 4 shown in P-1). With respect to beamforming in UE110, the measurement and selection typically involve UE Rx beam sweeps from different sets of beams.

[0037] P-2 (Procedure 2): This procedure enables UE measurements for different TRP transmit beams (e.g., TRP transmit beams 1, 2, 3, and 4 shown in P-2) and allows for modification of the transmit beam between / within TRPs while reducing the beamset for beam refinement compared to P-1. Note that P-2 can be a special case of P-1. As shown in Figure 2, TRP transmit beams 1, 2, 3, and 4 shown in P-2 are internal beams of beam 3(210) shown in P-1. Beam 3(210) is shown as a dashed ellipse in P-2.

[0038] P-3 (Step 3): When the UE uses beamforming, it enables UE measurements on the same TRP transmit beam and is used to change the UE receive beam. Therefore, as shown in Figure 2, UE110 can measure the TRP Tx beam 3 (210) and select the UE Rx beam 2 (220) based on the measurement results.

[0039] Regarding downlink beam indication, a quasi-collocation (QCL) indication function is defined. The principle for receiving a specific physical signal or physical channel is as follows: The UE configures, or implicitly determines, a previously received and measured source or reference RS. This RS defines how to set the RX beam for receiving the downlink (target) physical signal or channel to be received. A transmit configuration instruction (TCI) framework is defined to provide the UE110 with QCL characteristics for the target signal to be received. Using the TCI framework, the UE110 may be configured with one or more TCI states to provide one or more source reference signals (RS) for determining the QCL characteristics. Each TCI state includes one or two source RSs that provide the UE with parameters for QCL type A, type B, type C, and / or type D. Different types provide parameters as follows:

[0040] QCL Type A: {Doppler shift, Doppler spread, mean delay, delayed spread}

[0041] QCL Type B: {Doppler shift, Doppler diffusion}

[0042] QCL Type C: {Doppler shift, mean delay}

[0043] QCL Type D: {Spatial reception parameters}

[0044] The reference signals (RS) described herein include the synchronization signal block (SSB), channel status information reference signal (CSI-RS), tracking reference signal (TRS), and demodulation reference signal (DMRS).

[0045] In the uplink, the UE110 is provided with parameters called spatial relation information. This provides the spatial source RS, which the UE uses to determine the uplink transmit beam. The spatial source RS may be DL RS (SSB or CSI-RS) or UL RS (SRS). For each PUCCH and SRS resource, the gNB170 explicitly provides the spatial source. On the other hand, indirect instructions are provided for PUSCH (see 1-2 below).

[0046] 1. A PUSCH scheduled using DCI format 0_0, where the spatial source is identical to a specific PUSCH resource.

[0047] 2. A PUSCH scheduled in DCI format 0_1, where the spatial source is indicated as one or more SRS resources. That is, one SRS resource is indicated in the codebook-based transmission method, and one or more SRS resources are indicated in the non-codebook-based transmission method.

[0048] Rel-16 introduced default spatial relationships for dedicated PUCCHs and / or SRSs (excluding SRSs with usage = "beamManagement" and SRSs with usage = "nonCodeBook" in which the associated CSI-RS is configured). Specifically, if no spatial relationship is configured in FR2, the UE determines the spatial source in the following way: If one or more control resource sets (CORESETs) are configured on the CC, the UE determines the TCI state and / or QCL assumption of the control resource set (CORESET) with the lowest ID. On the other hand, if no CORESETs are configured on the CC, the UE determines the activated TCI state with the lowest ID that is applicable to the PDSCH in the CC's active DL-BWP.

[0049] Furthermore, Rel-16 introduces default spatial relationships for PUSCH scheduled by DCI format 0_0, and UE110 determines the spatial relationships as follows (1-2).

[0050] 1. If no PUCCH resources are configured on an active UL BWP CC, the default spatial relation is the TCI state and / or QCL assumption of the CORESET with the lowest ID, and the default path loss RS is the RS of QCL type D in the same TCI state and / or QCL assumption of the CORESET with the lowest ID.

[0051] 2. In FR2 and in RRC connection mode, if no PUCCH resource is configured on an active UL BWP CC, the default spatial relationship is the TCI state and / or QCL assumption of the CORESET with the lowest ID.

[0052] The default path loss RS is the RS of the same TCI state and / or QCL type D under the QCL assumption of the CORESET with the lowest ID.

[0053] Rel-17 introduces a unified TCI framework, which means that TCI states, which previously provided QCL assumptions for receiving DL signals and channels, will also be used to provide spatial sources for transmitting UL signals and channels, determining the UL TX spatial filter. Furthermore, the unified TCI framework defines the concept of "indicated TCI states," which means that one or more of the configured TCI states (e.g., in the case of multi-TRP) can simultaneously be indicated as one or more TCI states. An indicated TCI state may be a joint DL / UL TCI state, or a separate DL TCI state and a separate UL TCI state. Each indicated TCI state provides a QCL source (DL) for the downlink signal and channel set and a spatial source (UL) for the uplink signal and channel set. In Rel-17, for a UE, there may be one indicated joint DL / UL state, or one indicated DL TCI state and one indicated UL state.

[0054] Rel-18 extends the unified TCI framework to allow for multiple designated DL and UL TCI states.

[0055] Rel-15 supports both non-group-based and group-based beam reporting schemes for UEs in TS38.214. The network can be configured to report up to four CRIs and / or beams along with their L1-RSRP values ​​(via PUCCH or PUSCH). Group-based reporting is intended to provide the network with information about network-side beams (characterized by a reference signal) that the UE can receive simultaneously (including when using one or more spatial filters, i.e., panels).

[0056] In communications design, there is significant interest in supporting UE-initiated CSI reporting and beam switching. This not only significantly reduces the overall delay of these operations but also lowers the overhead of UL reporting.

[0057] Potential proposals in Rel-19 include the following (items 1-4 immediately following):

[0058] 1. Beam and / or channel state feedback update initiated by the UE.

[0059] 2. Accelerated beam acquisition: Addresses the increased L1 measurement load due to multi-cell, L1 and / or L2 mobility, etc. High-speed beam acquisition is possible using SSB correlation information. Reporting overhead can be reduced with UE-triggered reporting.

[0060] 3. Beam operations initiated by the UE contribute to the enhancement of FR2 operations. For example, beam selection in UE events (when the UE requests a "best" beam not associated with the DL RS) or when the UE initiates or triggers beam measurement and reporting.

[0061] 4. L1 beam measurement and / or reporting triggered by the UE or event trigger.

[0062] As mentioned above, a strong candidate in the discussions regarding MIMO for Rel-19 is the objective of UE-initiated CSI reporting and / or updates, including beam reporting and beam / TCI state switching.

[0063] A key aspect that needs to be defined in such UE-driven operations is the conditions and procedures that the UE must follow to determine and / or detect the need for CSI or beam reporting and / or updates and / or beam switching. Therefore, the embodiments described herein focus primarily on these aspects, with particular emphasis on the corresponding conditions / events.

[0064] In relation to the embodiments described herein, “best beam” is a beam having a higher L1-RSRP (compared to other beams), and “beat beam pair” is a beam pair in which the first beam and / or second beam have the highest L1-RSRP (compared to other pairs).

[0065] In the solutions described herein.

[0066] The UE110 receives a configuration for determining or detecting at least one event or condition, which is at least partially based on a reference signal such as the optimal beam or preferred beam, TCI status, and / or downlink reference signal.

[0067] The UE110 determines whether at least one condition or event has been met or occurred, based on the optimal or suitable beam, TCI status, and / or a reference signal such as the downlink reference signal. The UE110 may then provide the gNB170 with information related to this at least one condition or event.

[0068] This at least one condition or event includes one or more of the following (1-7):

[0069] 1. A change in at least one of N optimal or preferred beams, or CRIs (CSI-RS resource indicators or SSB resource indicators). These N beams or CRIs correspond to the beams or CRIs selected and reported to gNB170 if UE110 is configured. The number of beams (represented by N) may be 1 or more. If group-based beam reporting is configured in Rel-17 or Rel-18 (or even Rel-15), at least one condition or event includes a change in at least one of N optimal beam pairs, preferred beam pairs, or CRIs indicating a CSI-RS resource pair. These pairs may correspond to the pairs selected and reported to gNB170 if UE110 is configured.

[0070] 2. If the optimal beam or preferred beam, or at least one of the N optimal beams or preferred beams, has an L1-RSRP or L1-SINR or other CSI quantity below or above the threshold. If a group-based beam report for Rel-17 or Rel-18 is configured, at least one condition or event includes the L1-RSRP, L1-SINR, or other CSI quantity of the optimal beam pair, preferred beam pair, or at least one of the N optimal beam pairs or preferred beam pairs being below or above the threshold.

[0071] 3. If the average value of L1-RSRP or other CSI quantities (e.g., one or more of N optimal beams or CRIs, preferred beams or CRIs) changes significantly above a certain value, or falls below or above a threshold.

[0072] 4. If the RS measurement corresponding to the currently indicated TCI state changes compared to either Option 1 or Option 2. Option 1 is the RS measurement corresponding to any of the activated TCI states. Option 2 is the RS measurement in the pool of RS configured for measurement (the measurement can generally be L1-RSRP, L1-SINR, CQI, or other physical layer measurements).

[0073] 5. In one or more of the indicated TCI states or active TCI states, the corresponding CSI value (e.g., L1-RSRP or a set of L1-RSRPs) is higher or lower than the threshold.

[0074] 6. If, for one or more of the indicated TCI states, active TCI states, UL TCI states, or joint TCI states, the corresponding one or more MPE values ​​fall below or exceed the threshold.

[0075] 7. If at least one preferred ability set index or UE panel is changed.

[0076] Any of the above conditions or events may be defined as valid if they are met over a predetermined or set period. This period is represented by a timer, and the UE may start or restart the timer if at least one of the above conditions or events is met or occurs. The UE may then consider the condition or event valid only if the condition is met until the timer expires. Alternatively, any of the above conditions or events may be defined as valid if they are met consecutively a predetermined number of times. This number is set, for example, via RRC or indicated via MAC CE or DCI. Alternatively, any of the above conditions or events may be defined as valid if they are met a predetermined number of times within a certain period.

[0077] The above conditions and events may be defined for each group or set of CSI-RS resources, TCI states, beams, and reference signals (SSB, CSI-RS, TRS, DMRS, etc.). Each group or set of CSI-RS resources, TCI states, beams, and reference signals may correspond to or be associated with CORESETPoolIndex, PCI, SRS resource sets, TRP, etc. Measurements related to any of the above conditions or events may be performed based on the DMRS of DL channels such as PDSCH and PDCCH. In this case, the UE may be configured to perform measurements based on at least one of the following: PDCCH or PDSCH corresponding to or scheduled by one or more CORESETs, PDCCH or PDSCH corresponding to or scheduled by one or more search space sets, PDSCH compatible with one or more PDSCH configurations, PDCCH compatible with one or more PDCCH configurations, PDSCH or PDCCH that supports or are scheduled by one or more DCI formats, PDCCH or PDSCH on one or more carriers or BWP (bandwidth portion), PDSCH corresponding to a predetermined MCS (Modulation Coding Scheme) value, PDSCH corresponding to a specific time domain and / or frequency domain assignment, A PDCCH with a specific aggregation level.

[0078] The above conditions may be defined or set jointly or separately for DL ​​and UL.

[0079] When a reference to Layer 1 (L1) is made, Layer 3 (L3) may also apply. For example, at least one condition may be that the optimal beam or preferred beam, or at least one of N optimal beams or preferred beams, has an L3-RSRP or L3-SINR that is below or above a threshold.

[0080] A beam may correspond to, or be represented by, a spatial filter, UL beam, DL beam, TCI status, quasi-colocation information, reference signals (SSB, CSI-RS), SRS resources, SRS resource indicators, or SRS resource sets.

[0081] The UE110 may receive at least one configuration, for example via RRC or MAC CE, to determine or detect at least one of the above conditions or events.

[0082] The proposed thresholds, values, periods, timers, offsets, counts, etc. (above or below) can be set or instructed to the UE, either alone or as part of other configurations, via RRC, MAC CE, and / or DCI.

[0083] The UE110 can provide the network with information regarding any of the above conditions / events. This information may instruct the gNB170 to perform one of the above events. Specifically, it may instruct the gNB170 to perform an event and / or change that has occurred. Alternatively, this information may trigger or initiate a CSI or beam report, or a TCI state switch.

[0084] Referring to Figure 3, examples of UE operation include the following:

[0085] 310: Receives a configuration for determining at least one event or state based at least in part on the measured optimal and / or preferred beam, TCI state, and / or reference signal. In 310, UE110 receives a configuration for determining or detecting at least one of the following conditions or events: at least one change in N optimal or preferred beams (or CRI), at least one change in N optimal or preferred beam pairs, and at least one indicated or active TCI state, where the corresponding L1-RSRP is below a threshold.

[0086] 320: Determine that at least one condition or event has been met or occurred. In 320, the UE110 determines whether the corresponding L1-RSRP has fallen below a threshold for at least one change among the N optimal or suitable beams or CRIs, at least one change among the N optimal or suitable beam pairs, and at least one indicated or active TCI state.

[0087] 330: Sends information related to at least one condition or event to gNB170. In 330, UE110 provides gNB170 with information related to at least one of the above conditions or events.

[0088] Figure 4 shows an embodiment of the solution described herein that may be performed by user equipment. In 410, UE110 receives a configuration for determining or detecting the following event, including a timer value: a change in the optimal beam or preferred beam. In 420, UE110 determines the change in the optimal beam or preferred beam (or CRI). In 430, UE110 starts or restarts the timer. In 440, UE110 determines whether the change in the optimal beam or preferred beam (or CRI) is still valid. In 440, if UE110 determines that the change in the optimal beam or preferred beam (or CRI) is still not valid (e.g., "No"), the process proceeds to 450. In 440, if UE110 determines that the change in the optimal beam or preferred beam (or CRI) is still valid (e.g., "Yes"), the process proceeds to 460. In 450, UE stops or pauses the timer. In 460, UE determines whether the timer has expired. In step 460, if the UE determines that the timer has not expired (e.g., "No"), the process proceeds to step 440. In step 460, if the UE determines that the timer has expired (e.g., "Yes"), the process proceeds to step 470. In step 470, the UE110 provides the gNB170 with information related to the state or event.
