AI Technical Summary
Existing mobile communication systems are insufficient to meet the needs of various communication scenarios in terms of capacity, energy consumption, device cost, spectrum efficiency, and latency. In particular, in terms of UE auxiliary information reporting, the UE's reporting information may be too proactive or not proactive enough, leading to difficulties in network optimization.
Through information exchange between network nodes and terminals, network nodes send configuration information to request specific types of report information and comprehensively compare the received report information to evaluate the rationality of UE auxiliary information, including reporting the UE's current status and preferences, such as battery life, throughput, latency requirements, etc., to assist the network in minimizing drive tests and self-optimizing network optimization.
It enables effective evaluation of UE auxiliary information, helps network nodes optimize resource allocation, improve system performance, reduce unnecessary energy consumption and latency, and enhance the network's self-optimization capabilities.

[0021] Section headings are used in this document for ease of understanding and do not limit the scope of embodiments to the sections into which they are described. Furthermore, although embodiments are described with reference to a 5G example, the disclosed technology can be applicable to wireless systems that utilize protocols other than 5G or 3GPP protocols.
[0022] The development of new generation wireless communications (5G New Radio (NR) communications) is part of a continuous mobile broadband evolution process to meet the requirements of ever-increasing network demand. NR will provide larger throughput to allow more users to be connected at the same time. Other aspects such as energy consumption, device cost, spectrum efficiency, and latency are also important to meet the needs of various communication scenarios.
[0023] Figure 1 An example 5G network architecture 100 is shown. As shown, a fifth generation (5G) network architecture can include a 5G core network (5GC) and a next generation radio access network (NG-RAN). The 5GC can include any of an Access Mobility Function (AMF), a Session Management Function (SMF), and a User Plane Function (UPF). The NG-RAN can include base stations with different radio access technologies (RATs), such as evolved 4G base stations (ng-eNBs), 5G base stations (gNBs). The NG-RAN base stations can be connected to the 5GC through an NG interface, and the NG-RAN base stations can be connected through an Xn interface. Figure 1
[0024] Figure 2 An example signaling procedure for user equipment (UE) assistance information reporting 200 is shown. The purpose of this procedure is for the UE to inform the network about assistance information for power saving or handling overheating, in-device coexistence (IDC) issues, etc. In Figure 2 , a network node 204 can send an RRC reconfiguration message 206 to a UE 202. The UE 202 can send UE assistance information 208 to the network node 204.
[0025] However, the UE can report the UE assistance information more aggressively, or vice versa under certain considerations. For example, the UE can report that its preference for the maximum number of secondary component carriers is 0 (i.e., disabling carrier aggregation) to achieve the ultra-long battery life advertised in the advertisement. As another example, the UE can report that its preference for the maximum number of secondary component carriers is the maximum number of secondary serving cells to achieve the ultra-high throughput performance advertised in the advertisement.
[0026] System overview
[0027] This embodiment can involve evaluation of the UE assistance information. This can assist the network to evaluate whether the UE assistance information reported from the UE is too aggressive or vice versa.
[0028] The UE may report a first report information message to the network. The first report information message may include at least one of the following: average scheduling intervals for both downlink and uplink, average downlink scheduling interval, average uplink scheduling interval, number of physical downlink control channel (PDCCH) receptions per discontinuous reception (DRX) cycle or per configured time period, average percentage of active time in DRX cycles, number of consecutive DRX cycles with an active time percentage exceeding a configured threshold, number of DRX cycles with an active time percentage exceeding a configured threshold within a configured time period, the UE's current temperature, predicted hold-up time (after which the UE may have serious problems if the UE temperature does not decrease), severity of in-device coexistence (IDC) problems, interference measurements related to IDC problems, predicted throughput, predicted latency requirements, predicted time periods during which the UE will not send or receive data, and predicted latency requirements if user preferences are adopted by the network. The remaining battery life is measured; the predicted remaining battery life is calculated in the case where the user preference will not be adopted by the network; the predicted remaining battery life is calculated; the percentage of remaining battery life is calculated; the level of remaining battery life is calculated (e.g., high, medium, low; another example is index 1, 2, ... 10 representing 10%, 20%, ... 100%); the estimated full battery life is calculated after 100% recharge; the average recharge interval of the UE; the percentage of time the remaining battery life is below a configured threshold; UE capability information; UE category; UE type (e.g., ordinary UE, industrial sensor, video surveillance, wearable device); and the received signal strength indication for each cross-link interference (cross-link interference).

[0048] The first configuration information may be included in an existing Radio Resource Control (RRC) reconfiguration message, an existing log-based measurement configuration message, or a new message.
[0049] At 408, UE 402 can report first report information to network 404 based on the received first configuration information.
[0050] Example embodiment 3
[0051] Figure 5 This is a signaling procedure 500 for evaluating UE auxiliary information according to a third example embodiment.
[0052] In 506, UE 502 can report power saving preferences via UE Auxiliary Information Message.
[0053] At 508, network 504 sends the first configuration information to UE502 via a Radio Resource Control (RRC) reconfiguration message.
[0054] The first configuration information may include at least one of the following: information requesting a report of the percentage of remaining battery operating time, information requesting a report of the estimated full battery operating time after a 100% recharge, information requesting a report of the UE's average recharge interval, information requesting a report of the percentage of time the remaining battery operating time is less than a threshold, and / or a configuration threshold (e.g., 20%) used to calculate the percentage of time the remaining battery operating time is less than a configured threshold.

[0056] At 512, using the comprehensive comparison of the received first report information, network 504 can evaluate the received preference regarding power saving. For example, the network may consider the preference regarding power saving to be too aggressive; because the first report information indicates that the UE can have a long remaining battery life, can be recharged frequently, and rarely has less than 20% remaining battery life. The network may not adopt the preference regarding power saving from the UE, or may adopt an alternative approach regarding power saving.
[0057] Example embodiment 4
[0058] Figure 6 This is a signaling flow 600 for evaluating UE assistance information according to a fourth example embodiment. At 606, UE 602 can change its preference to leave the RRC_CONNECTED state via a UE assistance information message report.

[0061] At 612, using the comprehensive comparison of the received first report information, network 604 can evaluate the received preference for transitioning out of the RRC_CONNECTED state. For example, the network may consider the preference for transitioning out of the RRC_CONNECTED state to be too aggressive; because the first report information indicates that the UE may have a long remaining battery life and the predicted period during which the UE will not send or receive data is short. The network may not adopt the preference for transitioning out of the RRC_CONNECTED state from the UE.
[0062] Example embodiment 5

[0067] In 714, UE 702 can report power saving preferences via UE Auxiliary Information Message.
[0068] At 716, by comprehensively comparing the received first report information, network 704 can evaluate the received preference regarding power saving. For example, the network may consider the preference regarding power saving to be too aggressive; because the first report information indicates that the UE can have a long remaining battery life, can be recharged frequently, and rarely has less than 20% remaining battery life. The network may not adopt the preference regarding power saving from the UE, or may adopt a more moderate approach to power saving.
[0069] Example embodiment 6

[0073] At 810, using the comprehensive comparison of the received first report information, network 804 can evaluate the received preference for transitioning out of the RRC_CONNECTED state. For example, the network may consider the preference for transitioning out of the RRC_CONNECTED state to be too aggressive; because the first report information indicates that the UE may have a long remaining battery life and the UE predicts that the duration for which it will not receive or transmit data in the future is short. The network may not adopt the preference for transitioning out of the RRC_CONNECTED state from the UE.
[0074] Example embodiment 7

[0076] In 906, UE 902 can report first report information to the network for the purpose of minimizing drive test (MDT) (i.e., the first report information is the MDT measurement result or a part thereof) or for the purpose of self-optimizing network (SON). The first report information may include at least one of the following: UE capability information, UE category, UE type (e.g., general UE, industrial sensor, video surveillance, wearable device), periodic measurement results and CLI-RSSI resource index for each Cross-Link Interference Received Signal Strength Indication (CLI-RSSI) resource, periodic reference signal received power (RSRP) measurement results and SRS resource index for each Sounding Reference Signal (SRS) resource, event-triggered measurement results (e.g., triggered event I1 (interference becomes higher than the threshold)) and CLI-RSSI resource index for each CLI-RSSI resource, event-triggered RSRP measurement results (e.g., triggered event I1 (interference becomes higher than the threshold)) and SRS resource index for each SRS resource, and a preamble group indication indicating whether preamble group A or preamble group B was used (this indication may be for each random access RA procedure or for each RA attempt within each RA procedure). This indication may be a one-bit indication, where a value of "0" indicates preamble group A and a value of "1" indicates preamble group B, or vice versa. Alternatively, the indication can be enumerated from group A or group B. Alternatively, the indication can be the presence of group B, i.e., the appearance of the indication refers to preamble group B, and the absence of the indication refers to preamble group A, or an indication of whether the PUSCH configuration is used for the physical uplink shared channel PUSCH group of preamble group A or preamble group B (this indication can be for each RA process or for each RA attempt within each RA process).
[0077] This indication can be a one-bit indication, where a value of "0" indicates the PUSCH configuration for preamble group A, and a value of "1" indicates the PUSCH configuration for preamble group B, or vice versa. Alternatively, the indication can be an enumeration of either group A or group B. Alternatively, the indication can be the presence of group B, meaning its presence indicates the PUSCH configuration for preamble group B, and its absence indicates the PUSCH configuration for preamble group A. Alternatively, this indication can be derived from the preamble group indication (if the preamble group indication uses preamble group A, then the PUSCH configuration for preamble group A is used; otherwise, the PUSCH configuration for preamble group B is used), the number of preambles transmitted for each cell in a 4-step RA (or type 1 RA), the number of preambles transmitted for each beam in each cell in a 4-step RA (or type 1 RA), the number of preambles transmitted for each cell in a 2-step RA (or type 2 RA), the number of preambles transmitted for each beam in each cell in a 2-step RA (or type 2 RA), and / or MsgA PUSCH information used to specify the PUSCH resource allocation for MsgA in a 2-step RA.

The number of frequency domain multiplexed PUSCH timings (nrofMsgA-PO-FDM), the number of time domain PUSCH timings in each slot (nrofMsgA-PO-PerSlot), the number of PRBs for each PUSCH timing (nrofPRBs-PerMsgA-PO), the number of slots including one or more PUSCH timings (nrofSlotsMsgA-PUSCH), and / or an index giving the combination of start symbol, length, and mapping type as the start and length indicator for the first msgA PUSCH timing (startSymbolAndLengthMsgA-PO).
[0079] The first report information may be included in existing UE information response messages, existing measurement report messages, or new messages.
[0080] At 908, network 904 can process MDT measurement results. For example, the network can aggregate MDT measurement results for each UE category based on the receiving UE category. As another example, the network can better reduce cross-link interference based on CLI-RSSI and / or SRS-RSRP measurement results from the first reporting information of the MDT measurement results.
[0081] Example embodiment 8

[0122] Conclusion
[0123] The disclosed and other embodiments, modules, and functional operations described in this document may be implemented in digital electronic circuits, or in computer software, firmware, or hardware (including the structures disclosed in this document and their structural equivalents), or combinations thereof. The disclosed and other embodiments may be implemented as one or more computer program products, i.e., one or more modules of computer program instructions encoded on a computer-readable medium for execution by a data processing apparatus or for controlling the operation of a data processing apparatus. The computer-readable medium may be a machine-readable storage device, a machine-readable storage substrate, a memory device, a material composition affecting machine-readable propagation signals, or combinations thereof. The term "data processing apparatus" covers all devices, apparatuses, and machines for processing data, including, for example, a programmable processor, a computer, or multiple processors or computers. In addition to hardware, the apparatus may also include code that creates an execution environment for the computer program under consideration, such as code constituting processor firmware, a protocol stack, a database management system, an operating system, or combinations thereof. The propagated signal is an artificially generated signal, such as an electrical, optical, or electromagnetic signal generated by a machine, which is used to encode information for output to a suitable receiver device.
[0124] Computer programs (also known as programs, software, software applications, scripts, or code) can be written in any form of programming language, including compiled or interpreted languages; and they can be deployed in any form, including as standalone programs, or as modules, components, subroutines, or other units suitable for a computing environment. A computer program does not necessarily correspond to a file in a file system. A program may be stored as a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document); stored in a single file dedicated to the program in question; or stored in multiple coordinating files (e.g., a file storing one or more modules, subroutines, or portions of code). Computer programs can be deployed to execute on one or more computers located at a single point or distributed across multiple points and interconnected via a communication network.
[0125] The processes and logic flows described in this document can be executed by one or more programmable processors, which execute one or more computer programs to perform functions by manipulating input data and generating output. Processes and logic flows can also be executed by dedicated logic circuitry, and the device can also be implemented as dedicated logic circuitry, such as FPGA (field programmable gate array) or ASIC (application-specific integrated circuit).
[0126] Processors suitable for executing computer programs include, for example, both general-purpose and special-purpose microprocessors, and one or more processors of any kind of digital computer. Generally, a processor receives instructions and data from read-only memory or random access memory, or both. The basic components of a computer are a processor (for executing instructions) and one or more memory devices (for storing instructions and data). Generally, a computer will also include data, or be operatively coupled to receive data from or transfer data to one or more mass storage devices for storing data, such as magnetic disks, magneto-optical disks, or optical disks. However, a computer does not necessarily need to have such devices. Computer-readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media, and memory devices, such as semiconductor memory devices (e.g., EPROM, EEPROM, and flash memory devices), magnetic disks (e.g., internal hard disks or removable disks), magneto-optical disks, and CD-ROMs and DVD-ROMs. Processors and memory may be supplemented by or incorporated into dedicated logic circuitry.
