[0080] Figure 1 An example of a network 100 suitable for use with the examples of this disclosure is schematically illustrated. The network (also referred to as an NW) includes multiple network nodes, including: a terminal node 110 (also referred to as a user equipment UE), an access node 120 (also referred to as a radio access network RAN ​​node or base station), and one or more core network nodes 130. Terminal node 110 and access node 120 communicate with each other. In some, but not all, examples, one or more core network nodes 130 may communicate with each other. In some, but not all, examples, one or more access nodes 120 may communicate with each other.

[0081] In this example, network 100 is a wireless telecommunications network, i.e., RAN, in which at least some of the terminal nodes 110 and access nodes 120 communicate with each other using radio wave transmission / reception.

[0082] RAN 100 may be a cellular network comprising multiple cells 122, each cell being served by access node 120. Access node 120 includes a cellular radio transceiver. Terminal node 110 includes a cellular radio transceiver.

[0083] In the specific example shown, network 100 could be a new radio NR network of the 3rd Generation Partnership Project (3GPP) and its fifth-generation 5G technology. In other examples, network 100 could be a network other than 5G, such as a next-generation (i.e., sixth-generation 6G) wireless network currently under development (i.e., an NR network and its evolution into 5G technology).

[0084] The interface between terminal node 110 and access node 120 is radio interface 124 (e.g., Uu interface). The interface between access node 120 and one or more core network nodes 130 is backhaul interface 128 (e.g., S1 and / or next-generation NG interface).

[0085] Depending on the specific deployment scenario, access node 120 can be a RAN node such as an NG-RAN node. NG-RAN nodes can be gNodeBs or gNBs that provide NG user plane and control plane protocol termination to the UE. The gNB connects to the 5G core (5GC) via the NG interface, and more specifically, to the Access and Mobility Management Function (AMF) via the NG control plane NG-C interface, and to the User Plane Function (UPF) via the NG user plane NG-U interface. Access nodes 120 can interconnect with each other via Xn interface 126.

[0086] Cellular network 100 can be configured to operate in licensed or unlicensed frequency bands (especially: unlicensed frequency bands that rely on transmitting equipment to sense radio resources / mediums before transmission begins, such as via the Listen-After-Speak (LBT) process; and the 60 GHz unlicensed frequency band that may require beamforming to achieve the desired coverage).

[0087] Access node 120 can be deployed in NG standalone operation / scenario. Access node 120 can be deployed in NG non-standalone operation / scenario. Access node 120 can be deployed in carrier aggregation (CA) operation / scenario. Access node 120 can be deployed in dual-connectivity DC operation / scenario (i.e., multi-radio access technology - dual-connectivity MR-DC).

[0088] In this non-standalone / dual-connectivity deployment, access nodes 120 can interconnect with each other via X2 or Xn interfaces and connect to the Evolved Packet Core (EPC) via the S1 interface or to the 5GC via the NG interface.

[0089] Terminal node 110 is a user-side network element in the network that terminates the radio link. They are devices that allow access to network services. Terminal node 110 may be referred to as User Equipment (UE), mobile terminal, or mobile station. The term 'User Equipment' can be used to specify a mobile device that includes components for authentication / encryption, such as smart cards (such as Subscriber Identity Modules (SIMs)). The SIM / SIM card can be a memory chip, module, or Universal Subscriber Identity Module (USIM).

[0090] In some examples, the term 'user equipment' can be used to specify a location / location tag, a super / smart tag, or a mobile device that includes a circuitry system for authentication / encryption, such as a software SIM, embedded as part of the user equipment. The functionality of terminal node 110 can also be performed by the mobile terminal MT portion of the integrated access and backhaul IAB node.

[0091] Access node 120 is a network element in the network responsible for radio transmission and reception with terminal node 110 in one or more cells 122. Access node 120 is the network terminal of the radio link. Access node 120 can be implemented as a single network device or with a split architecture that uses different functional split architectures and different interfaces to decompose / distribute across two or more RAN nodes (such as central unit CU, distributed unit DU, remote radio head end RRH).

[0092] In the case where the access node 120 has a decomposed (split) architecture, the access node 120 may include one or more distributed units gNB-DU and centralized units gNB-CU ( Figure 1 (Not shown in the diagram). The gNB-CU is a logical node configured to host the Radio Resource Connection (RRC) layer and other layers of the access node 120. The gNB-CU controls the operation of one or more gNB-DUs. The gNB-DU is a logical node configured to host the Radio Link Control (RLC) protocol layer, Media Access Control (MAC) layer, and Physical PHY layer of the access node 120. The gNB-DU can communicate with the RRC layer hosted by the gNB-CU via a dedicated interface (e.g., an F1 interface). One gNB-DU can support one or more cells 122. A gNB or gNB-DU can host one or more Transmitter Receiver Points (TRPs). gNB-DU functionality can also be performed by the DU portion of the IAB node.

[0093] In the following description, the network will be referred to as NW 100, the access node / RAN node 120 will be referred to as gNB 120, and the terminal node 110 will be referred to as UE 110.

[0094] Before describing the example implementation in detail, we will now discuss the evolution of duplex operation in the new radio NR (referred to as subband non-overlapping full-duplex SBFD) and a new type of cross-link interference CLI (referred to as UE to UE CLI) that may emerge under SBFD deployment.

[0095] In Time Division Duplex (TDD), time-domain resources are split between the downlink and uplink. Allocating a limited duration for the uplink in TDD leads to reduced coverage, increased latency, and decreased capacity. A proposed approach is to provide both downlink and uplink simultaneously at the gNB side within the traditional TDD band, also known as full-duplex, or more specifically, SBFD.

[0096] Therefore, transmission time slots can have non-overlapping downlink (DL) subbands and uplink (UL) subbands. These time slots are called SBFD time slots. However, there can also be time slots where the entire frequency band is used for either DL or UL, i.e., non-SBFD time slots.

[0097] SBFD introduces a new type of cross-link interference CLI from non-overlapping frequency resources, called co-channel inter-subband CLI: •gNB self-interference • Intra-cell UE-to-UE co-channel subband CLI • Inter-cell UE-to-UE co-channel subband CLI (from non-overlapping frequency resources) • gNB-to-gNB co-channel subband CLI (from non-overlapping frequency resources)

[0098] The system may also be affected by co-channel CLI transmissions on overlapping frequency resources: • GNB-to-GNB inter-channel CLI from overlapping frequency resources • UE-to-UE inter-channel CLI from overlapping frequency resources

[0099] In 5G Advanced Release 18 (3GPP TR 38.858), flexible duplexing was investigated, introducing the use of SBFD time slots, encompassing both downlink (DL) and uplink (UL) transmission opportunities. As a non-limiting example, an enhanced radio frame configuration could consist of one DL time slot, followed by three SBFD time slots and one UL time slot. SBFD time slots can include resources for DL ​​transmission, UL reception, and protection resources (i.e., unused resources). This time slot format with concurrent DL and UL transmission opportunities can also be referred to as an X-slot.

[0100] Next, we will discuss CLI measurements.

[0101] Version 16 introduces a UE-to-UE CLI measurement framework to support dynamic time division duplex (TDD). Two new measurements are standardized: Probe Reference Signal Received Power (SRS-RSRP) and Cross-Link Interference Reference Signal Strength Indicator (CLI-RSSI).

[0102] Regarding SRS-RSRP measurements, the gNB configures a resource set for the attacker UE in the information element SRS-Config (see TS 38.331) (e.g., causing the attacker UE to send appropriately configured SRS at specific periods for measurement by the victim UE). Regarding CLI-RSSI measurements, the gNB also configures the victim UE to measure the received power within predefined resources to evaluate the CLI. In both cases (i.e., for each measurement of SRS-RSRP and CLI-RSSI), the measurement performed by the victim UE is configured in a measurement object MeasObjectCLI, which may contain indications of the SRS configuration used by the attacker UE to send the SRS (e.g., resources, periods, etc.) and / or the resources to be used in the CLI-RSSI measurement.

[0103] The victim UE can be configured to periodically report CLI measurements, or this can be triggered by an I1 event. TS38.331 specifies: For event I1, the measurement report event is based on CLI measurement results, which can be based on SRS-RSRP or CLI- It is derived from RSSI. Event I1: The interference becomes higher than the absolute threshold.

[0104] Note that the SRS-RSRP measurement requirements in TS 38.133 are for the SRS transmission period T. SRS As defined, no other parameters are used to configure the period during which the UE needs to measure SRS-RSRP. Therefore, after being configured, the UE will measure CLI at the same period that the gNB configures the attacker UE to send SRS. An example of the minimum requirement is as follows: Table 9.7.2.5-1 Measurement period T SRS_RSRP_measurement_period

[0105] The problem of UE-to-UE CLI can occur in dynamic TDD deployments, where cells may choose TDD frame configurations in an inconsistent manner. CLIs can exist in a deployment if a given time slot is selected for opposite link directions with two or more gNBs. In this case, the CLI is generated at the neighboring cell, and therefore we often refer to it as an inter-cell UE-to-UE CLI.

[0106] In SBFD operations, CLI can be caused not only by UEs between cells, but also by UEs within the same cell, depending on the leakage of transmissions in the UL subband of the attacker UE into the DL subband of another UE.

[0107] One method for performing inter-UE subband CLI measurements (hereinafter referred to as CLI measurements) is to have the victim UE measure the RSRP of the attacker UE within the UL subband, hereinafter referred to as CLI-RSRP.

[0108] Figure 2 The illustration schematically depicts attacker UE 1102, which has been configured by the network to send SRS at a given period. The network configures victim UE 1 and UE 2 to perform measurements on the same SRS resources to execute corresponding CLI-RSRP measurements. Victim UE 2 (located closer to the attacker UE than victim UE 1) may experience a higher CLI rate than victim UE 1. However, under the conventional / current procedure for measuring CLI, both UEs perform CLI measurements at the same period. The performance of this CLI measurement affects the UE's power consumption.

[0109] After gNB configuration measurements, the victim UE needs to perform measurements continuously at the same interval as the attacker UE sending SRS. This is to enable the victim UE to report its corresponding measurements according to the minimum requirements defined in RAN4 of TS 38.133. This will affect the UE's power consumption. Such reporting of CLI measurements will affect the UE's power consumption.

[0110] With periodic reporting configured, the gNB will acquire CLI measurement reports and can evaluate the CLI at the UE. With UE reporting configured to trigger reporting, the UE will only report it when event I1 occurs. Therefore, even if the CLI measurement never exceeds the threshold for event I1, the UE will continue to measure SRS, wasting power, even if it is not reported to the network. The performance of this CLI measurement affects the UE's power consumption.

[0111] Furthermore, scheduling limitations exist in TS 38.133 during CLI measurements. The network cannot assume that a UE has the capability to simultaneously measure CLI and receive PDCCH, PDSCH, or CSI-RS unless the UE reports to the network that it supports CLI-SRS-RSRP-FDM_DL capabilities. This may inevitably impact DL throughput. During CLI measurements, it is expected that no UE will send PUCCH / PUSCH / SRS. Therefore, the network needs to consider this when deciding how to configure a UE to perform CLI measurements on certain resources and on which resources to schedule the UE.

[0112] The various examples disclosed herein seek to address power consumption issues at the UE when performing UE-to-UE CLI SRS-RSRP measurements (hereinafter referred to as CLI-RSRP measurements), as well as reporting and scheduling limitations of the UE when performing such measurements.

[0113] Figure 3 A flowchart illustrating an example of method 300 according to this disclosure is schematically shown.

[0114] Figure 3 The component box is functional, and the described functionality can be performed by a single physical entity (as referenced). Figure 7 The described functions can also be implemented by computer programs (as described in the reference). Figure 8 (as described). Figure 3 This can be seen as illustrating multiple methods because Figure 3 This can be viewed as an illustration of one or more actions performed by multiple actors / entities (e.g., (victim) UE 110 and gNB 120). Therefore, Figure 3 It can be viewed as a diagram illustrating multiple individual methods performed by each corresponding individual executor / entity among multiple executors / entities.

[0115] Figure 3 The boxes shown can represent actions in a method, functions performed by a device, and / or instruction / code portions in a computer program.

[0116] In box 301, the gNB determines the configuration information, which is used to configure the UE: Measure UE-to-UE cross-link interference CLI, and / or Report one or more UE-to-UE CLI measurements to the RAN node.

[0117] The configuration information can configure the UE as follows: Measure the UE to the UE CLI at a specified measurement period, and / or Report UE measurements to the UE CLI at a specified reporting period.

[0118] The measurement cycle can be configured independently of the reporting cycle.

[0119] UE-to-UE CLI measurements may include one or more of the following, or a combination thereof: Measurement of a reference signal transmitted by a second UE (e.g., an attacker UE); Detection Reference Signal (SRS) and Reference Signal Received Power (RSRP) Measurement; and CLI-RSRP measurement.

[0120] In box 302, gNB sends configuration information 303 to UE 110.

[0121] In block 304, the gNB determines information including standard information that indicates one or more standards used to enable the UE to determine whether to operate in a first operating mode or a second operating mode. Therefore, this standard information indicating one or more standards can be used by the UE to enable the UE to determine whether to switch between the first and second operating modes, for example, if the UE determines that its current operating mode does not correspond to an operating mode determined based on standards.

[0122] The UE's first operating mode is a mode in which the UE measures UE to UE CLI and / or reports one or more UE to UE CLI measurements performed by the UE based on the first configuration information.

[0123] The second operating mode of the UE is a mode in which UE measures and / or reports one or more UE-to-UE CLI measurements performed by the UE, although not according to the first configuration information. For example, in the second operating mode, the measurement and / or reporting may occur at a period different from the initial configuration period of the configuration information (e.g., with a longer / extended measurement period duration).

[0124] In box 305, the gNB sends standard information 306 to the UE.

[0125] In some examples, one or more criteria for the standard information include at least one of the following: • Threshold UE-to-UE CLI measurement (e.g., if the current UE-to-UE CLI measurement is less than the threshold UE-to-UE CLI measurement, the UE determines that it should be in the second operating mode, while if the UE is currently in the first operating mode, the UE switches to the second operating mode). • Offset from the threshold UE-to-UE CLI measurement. The threshold UE-to-UE CLI measurement can be a configured threshold UE-to-UE CLI measurement configured via first configuration information. The offset can be an offset relative to the value of an I1 event (e.g., if the current UE-to-UE CLI measurement is less than the offset from the configured threshold, the UE determines that it should be in the second operating mode, while if the UE is currently in the first operating mode, the UE switches to the second operating mode). • The threshold difference between the first UE-to-UE CLI measurement and the second UE-to-UE CLI measurement; (for example, if the difference between the first UE-to-UE CLI measurement and the second UE-to-UE CLI measurement is less than the threshold amount, the UE determines that it should be in the second operating mode, while if the UE is currently in the first operating mode, the UE switches to the second operating mode). • A threshold difference between the current UE-to-UE CLI measurement and the most recently reported second UE-to-UE CLI measurement (e.g., if the difference between the current UE-to-UE CLI measurement and a previously / most recently reported UE-to-UE CLI measurement to the gNB is less than a threshold amount, the UE determines that it should be in the second operating mode; if the UE is currently in the first operating mode, the UE switches to the second operating mode, where in the second mode, the UE only reports UE-to-UE CLI measurements if the difference between the current measurement and the last reported measurement exceeds a threshold amount); and • A standard indicating the radio link quality of the cell serving the UE (e.g., if the UE is determined to be in a high-quality cell, i.e., the radio link quality of the cell serving the UE exceeds a threshold amount, then the UE determines that it should be in the second operating mode, while if the UE is currently in the first operating mode, then the UE switches to the second operating mode).

[0126] The threshold / offset of the standard information used to adjust CLI measurement requirements (e.g., relaxing measurement by increasing the measurement cycle) may be different from the threshold / offset of the standard information used to adjust reporting requirements (e.g., relaxing reporting by increasing the reporting cycle).

[0127] In some examples, if one or two or more criteria are met, the UE determines that it should be in a specific operating mode (e.g., a second operating mode). In some examples, if all criteria in the set are met, the UE determines that it should be in a specific operating mode. If the UE's current operating mode does not correspond to the determined operating mode, the UE can switch operating modes. In practice, in some examples, the UE can switch between operating modes if one configuration criterion, two or more configuration criteria, or all configuration criteria are met.

[0128] In box 307, the UE uses standard information to determine whether one or more standards have been met.

[0129] In box 308, at least in part based on determining whether one or more criteria have been met, the UE determines which operating mode it should be in, i.e., whether it should be in the first operating mode or the second operating mode. In this respect, the UE determines whether it should: Perform UE-to-UE CLI measurements and / or UE-to-UE CLI measurement reports based on the first configuration information; or Perform UE-to-UE CLI measurements and / or report UE-to-UE CLI measurements, even if not based on the initial configuration information (e.g., at a longer period than initially configured).

[0130] Based at least in part on the determination that its current operating mode does not correspond to the operating mode determined in box 308, the UE can switch itself between the first operating mode and the second operating mode.

[0131] For example, the UE can be configured via first configuration information to perform UE-to-UE CLI measurements in a first period. However, in a second operating mode, the UE can perform UE-to-UE CLI measurements in a second period, different from the first period. The second period can be configured to the UE by the gNB (i.e., the gNB can send the second period to be used to the UE). Alternatively, the second period can be predefined or defined in a standard / specification. For example, the second period could correspond to the first period multiplied by a scaling factor, which could be specified in the minimum UE requirements or configured by the network.

[0132] Similarly, the UE can be configured via first configuration information to report UE-to-UE CLI measurements at a third period (in some examples, this may correspond to the first period). However, in the second operating mode, the UE reports UE-to-UE CLI measurements at a fourth period, different from the third period (in some examples, the fourth period may correspond to the second period, for example, such that in the second operating mode, in some examples, the increase in the period for performing UE-to-UE CLI measurements may correspond to the increase in the period for reporting UE-to-UE CLI measurements).

[0133] In some examples, the UE may be configured via first configuration information to report UE-to-UE CLI measurements at least in part based on determining that a first triggering criterion is met (e.g., determining that the measured UE-to-UE CLI measurement exceeds the UE-to-UE CLI measurement value for an I1 event). However, after transitioning to a second operating mode, the UE reports UE-to-UE CLI measurements when a second triggering criterion is met, wherein the second triggering criterion differs from the first triggering criterion (e.g., a criterion that only sends a report when the difference between the current UE-to-UE CLI measurement and a previously reported UE-to-UE CLI measurement exceeds a threshold).

[0134] In box 309, the UE can send information 310, operating mode information, to the gNB, such as information indicating the UE's current operating state. For example, if the UE switches between a first operating mode and a second operating mode after box 308, the UE can report its current operating state to the gNB.

[0135] In some examples, the UE can report information indicating that it has switched between a first operating mode and a second operating mode. In this regard, the UE can report to the gNB that it has changed from one operating mode to another.

[0136] The gNB can use information about when the UE enters or leaves the second operating mode to update / reconfigure the attacker UE's SRS transmissions (by modifying its cycle or stopping the transmission of resources used for SRS transmissions).

[0137] In some examples, the gNB can determine whether to schedule at least one of the following based at least in part on the received indication: Transmission to the UE; Transmitted to the UE's Physical Downlink Control Channel (PDCCH); Transmission to the Physical Downlink Shared Channel (PDSCH) of the UE; and Transmit the Channel State Information Reference Signal (CSI-RS) to the UE.

[0138] In some examples, the gNB may determine, at least in part, whether to reconfigure / adjust the reference signal transmission of the second UE (e.g., adjust the SRS transmission of the attacker UE, especially adjust its period, etc.) based on the received indications.

[0139] In some examples, the UE can be configured with an additional criterion to assess whether the UE has lower CLI measurement variability compared to previously reported CLI measurements. In this regard, the UE evaluates the current CLI measurement CLI-RSRP1 and compares it to the last reported CLI measurement CLI-RSRPX. If |CLI-RSRP1 - CLI-RSRPX| < a threshold, the criterion is satisfied (and the UE does not report the current CLI measurement). In this way, if the UE's current CLI measurement is within the threshold of the previously reported CLI measurement, the UE can operate in a relaxed mode, where CLI measurement reporting is skipped (i.e., reporting of the current CLI measurement is postponed until the current CLI measurement exceeds the threshold of the most recently reported CLI measurement). This can save UE power consumption, network resources, and signaling overhead by reducing the number and frequency of CLI measurement reports.

[0140] Figure 3 The flowchart illustrates one possible scenario. The order of the boxes shown is not strictly necessary; therefore, in principle, boxes can be executed out of order (e.g., boxes 303 and 305). Not all boxes are necessary (e.g., box 309). In some examples, one or more boxes may be executed in a different order or overlapping, concatenated, or parallel in time (e.g., boxes 303 and 306 may be executed together). One or more boxes may be omitted, added, or changed in some combination.

[0141] An example of the invention according to this disclosure provides a method for a victim UE to inform its serving gNB that it is in an acceptable CLI condition relative to a particular attacker UE, and therefore it can relax CLI measurements, for example, by increasing the period of CLI measurements.

[0142] Advantageously, this can reduce the CLI measurement burden at the victim UE. Furthermore, if the UE is in a second operating mode (i.e., relaxed measurement mode), it can prioritize receiving or transmitting data instead of performing CLI measurements, which will improve throughput.

[0143] Figure 4 The flowchart of method 400 is shown.

[0144] In box 401, the method / procedure begins.

[0145] In box 402, the network configures the UE (e.g., a "victim" UE that is (or may be) affected by CLI from another "attacker" UE) to perform CLI measurements and report CLI measurements. Such CLI measurements can be CLI-RSRP measurements, i.e., measurements of the received power of CLI-SRS transmitted by the attacker UE, which has been configured by the gNB to do so. This configuration of the victim UE can be achieved via the transmission of configuration information from the gNB to the UE (e.g., ...). Figure 3 (as shown in box 303). In this regard, the gNB can configure the victim UE using CLI measurements and reports that specify a given SRS resource from the attacker UE. Configuration information may include one or more of the following: SRS-PeriodicityAndOffset The SRS measurement period T configured in the middle SRS Discontinuous reception DRX period length T DRX and in MeasObjectCLI CLI measurements and reports are configured periodically.

[0146] The configuration information enables the UE to operate in a first operating mode. In the first operating mode, the UE performs CLI measurements and CLI reports according to the configuration information (i.e., configured by the network). For example, in the first operating mode, the UE can periodically measure CLI according to the configuration information, and the UE can report periodically or non-periodically according to the configuration information (e.g., when it is determined that the CLI measurement exceeds a configured CLI threshold).

[0147] gNB can also include (or can send separately) configuration information, such as in Figure 3 In box 306, standard information is provided to enable the UE to determine which operating state it should be in (i.e., the first operating mode or the second operating mode), thereby determining whether to switch between the first and second operating modes. In the second operating mode, the UE still performs CLI measurements and reports, but the performance of the measurements and reports does not conform to the configuration information. For example, measurement and reporting requirements can be "relaxed" because the frequency / number of CLI measurements and CLI reports can be reduced compared to what was initially configured by the network.

[0148] In this regard, in the second operating mode, the CLI measurement period can be increased (reducing the measurement frequency and thus saving power for the UE). Similarly, in the second operating mode, the period or CLI threshold level used to trigger CLI reporting measurements can be increased (making reporting less frequent and thus saving power and network resources for the UE).

[0149] In the second operating mode, measurement and reporting requirements may therefore have extended time periods and / or increased CLI threshold triggering conditions, thus “relaxing” the measurement and / or reporting standards / conditions. Here, the second operating mode may be referred to as the “relaxed mode,” and the standards / parameters used to determine which operating mode will be in (and therefore whether to switch between the first and second operating modes) may be referred to as the relaxed standards.

[0150] The gNB can send one or more relaxation criteria / standard parameters along with configuration information, or the gNB can send one or more relaxation criteria / standard parameters separately.

[0151] One such relaxation criterion / parameter is the offset from the event I1 threshold (referred to as OT1 in this document, while the event I1 threshold is referred to as TI1). OT1 is the CLI-RSRP offset value, i.e., the offset from IT1. In some examples, if the UE determines that it should operate in relaxed mode, and transitions to (and remains in) relaxed mode if it is not already in relaxed mode, then the UE's CLI-RSRP measurement will need to be lower than OT1 (relative to IT1).

[0152] Another configurable relaxation criterion for the UE is the CLI-RSRP change threshold. RT (which can be used to indicate the variability of CLI measurements, and therefore can be used to indicate mobility, i.e., low) The RT value indicates low variability of CLI-RSRP during the measurement period, and also low mobility during the measurement period. In some examples, if the UE needs to determine that it should operate in relaxed mode, and if it is not already in relaxed mode, then transition to (and remain in) relaxed mode, the variability of the UE's CLI-RSRP measurement needs to be lower than [a certain value]. RT.

[0153] Another relaxation criterion that a UE can be configured with is a good cell quality criterion, such as a threshold for a metric indicating the serving cell radio link quality value (called RT2), like the synchronization signal RSRP (SS-RSRP). In some examples, if the UE needs to determine that it should operate in relaxed mode, and if it is not already in relaxed mode, then transition to (and remain in) relaxed mode, the UE's cell quality will need to be higher than RT2.

[0154] In box 403, the UE initiates CLI measurements and reporting according to its configuration. In this regard, the UE operates in a first operating mode, where it performs CLI measurements and reporting as initially configured by the network.

[0155] In block 404, the UE evaluates each of the different relaxation criteria, i.e., determines whether it should operate in the relaxation mode and thus whether it should transition to the relaxation mode.

[0156] In this regard, the UE evaluates whether all or one or more of the following relaxation criteria are satisfied: 1a. Low CLI criterion. This criterion is used to evaluate whether the measured CLI-RSRP is lower than a (relative) threshold, i.e., an offset below the event I1 threshold (if the event I1 threshold is configured). If CLI-RSRP < TI1-OT1, then this criterion is satisfied. The UE can determine that it should operate / transition to the relaxation mode at least in part based on the criterion being satisfied. 1b. Low CLI criterion. This criterion is used to evaluate whether the measured CLI-RSRP is lower than an (absolute) threshold. If CLI-RSRP < RT, then this criterion is satisfied. The UE can determine that it should operate / transition to the relaxation mode at least in part based on the criterion being satisfied. 2. Low CLI variability criterion (if configured). This criterion is used to evaluate whether the UE has low CLI measurement variability. The UE evaluates two CLI measurements (e.g., two consecutive CLI measurements) collected at different times: CLI-RSRP1 and CLI-RSRP2, and compares them. If │CLI-RSRP1 - CLI-RSRP2│ < RT, then this criterion is satisfied. The UE can determine that it should operate / transition to the relaxation mode at least in part based on the criterion being satisfied. 3. Good cell quality criterion (if configured). This criterion is used to evaluate whether the UE is in good cell quality. The UE can evaluate whether the measured SS-RSRP varies above a preconfigured value. If: SS-RSRP > RT2, then this criterion is satisfied. The UE can determine that it should operate / transition to the relaxation mode at least in part based on the criterion being satisfied. In this way, only UEs in good cell quality can transition to the relaxation mode to relax their CLI measurements and reporting (e.g., UEs at the cell edge are more likely to degrade due to high CLI and thus need to remain in the first operating mode).

[0157] If the UE evaluates that at least one of the relaxation criteria it is configured with is not satisfied, the UE remains in the first operating mode. The process returns to block 403, where the UE measures the CLI and reports it according to the configuration received in block 402.

[0158] If the UE evaluates that all of its configured relaxation criteria are met, it enters a relaxation mode / state (i.e., it transitions from the first operating mode to the relaxation mode) and notifies the network.

[0159] exist Figure 4 In certain examples, the UE enters a relaxed state in response to determining that the relaxation criteria for all configurations in the relaxation criteria have been met / satisfied. However, it should be understood that the UE entering a relaxed state does not always require that the relaxation criteria for all configurations in the relaxation criteria have been met / satisfied. In some examples, the UE determines whether to remain in the first operating mode or enter the second operating mode / relaxed state based at least in part on whether the relationship criteria for one or more configurations have been met. For example, the UE may enter a relaxed state in response to evaluating that a specified combination of the relaxation criteria for the configuration has been met.

[0160] In some examples, the determination of whether the UE remains in the first operating mode or enters the second operating mode / relaxed state can be based, at least in part, on alternative criteria being met, which include or consist of criteria other than the configured relaxation criteria.

[0161] In some examples, the relaxation state can be defined / controlled by one or more scaling factors (e.g., K1, K2, and K3 below), which adjust the measurement period for each CLI measurement. The scaling factors can be specified in the minimum UE requirements or configured by the network.

[0162] In box 405, the UE notifies the network that it is entering or has entered relaxed mode. In this regard, the UE can send gNB UE assistance information indicating whether it is entering or has entered relaxed mode.

[0163] In block 406, the UE performs CLI measurements and reporting, but not as initially configured in block 402. Instead, CLI measurements and reporting are performed in a more relaxed manner. In this relaxed mode, the period and / or reporting requirements are relaxed / reduced. For example, the measurement period can be increased, and reports can be sent less frequently.

[0164] In box 407, the UE continues to evaluate the relaxation criteria and check whether they are still met, i.e., so that the UE can remain in the relaxation mode.

[0165] In box 408, when it is determined that the relaxation criteria are not still fully met, the UE notifies the network that it is leaving or has left the relaxation mode, i.e., it is (re)entering the first operating mode. The process then returns to box 403, where the UE measures the CLI and reports the CLI according to the configuration received in box 402.

[0166] Advantageously, the method according to this disclosure enables the UE to be configured to periodically measure CLI, and also enables the UE to be configured with one or more relaxation criteria to indicate to the UE when the time interval between CLI measurements can be relaxed, i.e., extended.

[0167] Figure 5 The timeline of CLI measurements is illustrated, and different thresholds (e.g., TI1 and TI1-OT1) and offsets (e.g., (RT). In this figure, the timeline is scaled across multiple T_SRS_measurement_periods.

[0168] In each time period, the UE measures CLI-RSRP and compares the average CLI-RSRP value of the measurement period with TI1-OT1 to assess whether the low CLI criterion (relaxation criterion 1a above) is met. In the example shown, the low CLI criterion is not met in SRS measurement period 8 (which would trigger a transition from relaxed mode to the first operating mode - not shown).

[0169] If configured, the UE can also compare measurements taken at different times to assess whether the low CLI variability criterion (relaxation criterion 2 above) is also met. In this example, the low mobility criterion is not met for the first time between SRS measurement periods 5 and 6 (the low mobility criterion is also not met between SRS measurement periods 6 and 7 and between 7 and 8). This will trigger a transition from the relaxed mode to the first operating mode (not shown).

[0170] Figure 6 The diagram illustrates a signaling diagram showing the signaling between network NW 100 (i.e., via transmissions from / to the gNB), attacker UE 1102, and victim UE 1101.

[0171] In Transmission 600, NW configures the attacker UE to send SRS.

[0172] In transmission 601, NW configures the victim UE to measure and report CLI. This corresponds to Figure 3 and Figure 4 Boxes 306 and 402.

[0173] In transmission 602, NW configures relaxation criteria for the victim UE, such as parameter values / thresholds used to assess whether the victim UE should transition to / exit the relaxation mode. This corresponds to Figure 3 and Figure 4 Boxes 303 and 402.

[0174] In transmission 6031-603 n In this process, the attacker periodically sends SRS according to the configuration received in transmission 600. The victim UE operating in the first operating mode performs CLI measurements and reports of the SRS (not shown). In this respect, the victim UE's CLI measurements and reports are performed according to the configuration received from the NW in transmission 601.

[0175] In block 604, the victim UE assesses whether all relaxation criteria (which the victim UE is configured to have via transmission 602) have been met. In response, in transmission 605, the victim UE (via a UE auxiliary message) notifies the NW that it is entering relaxation mode.

[0176] In box 606, the victim UE enters relaxation mode.

[0177] In transmission 6071-607 n In this context, the attacker continues to periodically send SRS according to the configuration received in transmission 600. The victim UE, now operating in relaxed mode, does not perform CLI measurements and reports (not shown) of SRS according to the configuration received from the NW in transmission 601, but instead performs CLI measurements and reports in a more relaxed manner as described above, resulting in fewer measurements and reports being performed and sent, thereby saving UE power consumption, NW resources, and signaling overhead.

[0178] In block 608, the victim UE evaluates that at least one of the relaxation criteria (which the victim UE is configured to meet via transmission 602) is no longer satisfied. In response, in transmission 609, the victim UE notifies the NW (via a UE auxiliary message) that it is leaving the relaxation mode.

[0179] In box 610, the victim UE leaves the relaxation mode.

[0180] In some examples, in addition to or instead of the methods described above for determining the operating mode in which the UE should operate and for determining whether to switch between the first operating mode and the second / relaxed operating mode, the following process may be adopted, for example, in the second / relaxed mode, to further reduce the number and frequency of CLI measurement reports (thereby saving UE power, NW resources and signaling overhead).

[0181] In this regard, the victim UE can be configured to perform periodic measurements, causing the UE to send a CLI report containing previous measurements according to the configured reporting interval (e.g., as defined in CLI-PeriodicalReportConfig-r16::reportInterval-r16).

[0182] To relax CLI measurement reporting requirements to reduce the number of reports sent and thus reduce UE power consumption, the UE is configured to periodically measure and report CLI (as configured in MeasObjectCLI). In addition, the UE also receives parameter A (CLI-PeriodicalReportConfig-r18::reportCLIRange-r18), which configures the minimum required difference between the current CLI measurement and the previously reported CLI measurement.

[0183] This relaxation criterion / condition is used to determine whether a new CLI measurement will be sent / reported.

[0184] If the CLI measurement of the UE at time t1 is within the interval [CLI_t0 - parameter A, CLI_t0 + parameter A], where CLI_t0 is the latest reported CLI measurement at time t0, then the UE decides to skip the reporting of the CLI measurement.

[0185] Advantageously, this can enable the reduction of potentially unnecessary CLI measurement reports, thereby reducing the overhead for periodic measurements and reports.

[0186] Reports of skipped CLI measurements can indicate to the gNB that the CLI conditions have not changed or have not changed significantly relative to the most recently received CLI measurement report.

[0187] If the measured CLI is not within the above range, that is, the current CLI measurement has changed sufficiently relative to the latest reported CLI measurement, the UE sends a new CLI measurement report, because the new CLI measurement report is expected to provide meaningful information to the gNB.

[0188] It should be understood that the above-described process for reducing the number and frequency of CLI measurements can be independent of the above-mentioned procedures. Figures 3 to 6 Other UEs discussed are adopted by relaxing the UE CLI standard.

[0189] It should be understood that Figures 3-6Each of the boxes and block combinations shown, as well as the other functions described above, can be implemented in various ways, such as hardware, firmware, and / or software including one or more computer program instructions. For example, one or more of the functions described above can be performed by a suitably configured device (such as a UE or gNB, which includes components for performing the functions described above). One or more of the functions / functionalities described above can be embodied by a suitably configured computer program (such as a computer program including computer program instructions that embody the functions / functionalities described above, which can be stored in a memory storage device and executed by a processor).

[0190] As will be understood, any such computer program instructions can be loaded onto a computer or other programmable device (i.e., hardware) to produce a machine, such that the instructions, which execute on the programmable device, create parts for implementing the function / functionality specified in the box. These computer program instructions can also be stored in a computer-readable medium that can instruct the programmable device to operate in a particular manner, such that the instructions stored in a computer-readable memory produce an article of art including instruction parts that implement the function specified in the box. Computer program instructions can also be loaded onto a programmable device to cause a series of operations to be performed within the programmable device, thereby producing a computer-implemented process, such that the instructions, which execute on the programmable device, provide actions for implementing the function / functionality specified in the box.

[0193] Therefore, these boxes support: combinations of components for performing a specified function; combinations of actions for performing a specified function; and computer program instructions / algorithms for performing a specified function. It will also be understood that each box and combination of boxes can be implemented by a dedicated hardware-based system that performs the specified function or action, or by a combination of dedicated hardware and computer program instructions.

[0194] Various, but not limited to, examples of this disclosure provide a method and corresponding apparatus, the apparatus comprising various modules, components, or circuit systems that provide functionality for performing / applying the actions of the method. These modules, components, or circuit systems may be implemented as hardware or as software or firmware executed by a computer processor. In the case of firmware or software, examples of this disclosure may be provided as a computer program product comprising a computer-readable storage structure embodying computer program instructions (i.e., software or firmware) for execution by a computer processor.

[0195] Figure 7 The illustration schematically depicts the execution of the functions described in this disclosure and Figures 3-6 The diagram illustrates a block diagram of an apparatus 10 for methods, processes, procedures, and signaling. In this respect, the apparatus can perform the role of UE 110 or gNB 120 in the methods shown and described above. Figure 7 The component box is functional, and the described functionality can be performed by a single physical entity.

[0196] The device includes a controller 11, which can be located in a device such as a UE 110 or gNB 120.

[0197] The controller 11 may be embodied by a computing device, particularly those described above. In some, but not all, examples, the device may be embodied as a chip, chipset, circuit system, or module, i.e., for any of the above. As used herein, 'module' refers to a unit or device that does not include certain parts / components added by the end manufacturer or user.

[0198] The controller 11 can be implemented as a controller circuit system. The controller 11 can be implemented solely in hardware, have certain aspects in software, including separate firmware, or can be a combination of hardware and software (including firmware).

[0199] The controller 11 can be implemented using instructions capable of performing hardware functions, for example, by using executable instructions of a computer program 14 in a general-purpose or special-purpose processor 12, which can be stored on a computer-readable storage medium 13, such as a memory or a disk, for execution by such a processor 12.

As used herein, the term "non-transitory" refers to a limitation on the medium itself (i.e., tangible, not tactile), rather than a limitation on the persistence of data storage (e.g., RAM vs. ROM). In some, but not all, examples, computer program instructions may be distributed across multiple computer programs.

[0203] Although memory 13 is illustrated as a single component / circuit system, it can be implemented as one or more separate component / circuit systems, some or all of which may be integrated / removable and / or provide permanent / semi-permanent / dynamic / cached storage.

[0204] Although processor 12 is illustrated as a single component / circuit system, it can be implemented as one or more separate components / circuit systems, some or all of which may be integrated or removable. Processor 12 may be a single-core or multi-core processor.

[0223] References to 'computer program,' 'computer-readable storage medium,' 'computer program product,' 'tangibly embodied computer program,' or 'controller,' 'computer,' 'processor,' etc., should be understood to encompass not only computers with different architectures, such as single / multiprocessor architectures and sequential (von Neumann) / parallel architectures, but also special-purpose circuits, such as field-programmable gate arrays (FPGAs), application-specific circuits (ASICs), signal processing devices, and other devices. References to computer programs, instructions, code, etc., should be understood to encompass software or firmware used with programmable processors, such as the programmable content of hardware devices, whether instructions for the processor or configuration settings for fixed-function devices, gate arrays, or programmable logic devices, etc.

[0224] As used in this application, the term 'circuit system' may refer to one or more or all of the following: (a) Hardware circuit implementation only (such as implementation in analog and / or digital circuit systems only) and (b) A combination of hardware circuitry and software, such as (if applicable): (i) A combination of (multiple) analog and / or digital hardware circuits and software / firmware, and (ii) Any part of a hardware processor (including digital signal processors), software, and memory (including multiple memory) having software, which work together to enable a device such as a mobile phone or server to perform various functions, and (c) (Multiple) hardware circuits and / or (multiple) processors, such as (multiple) microprocessors or portions of (multiple) microprocessors, which require software (e.g., firmware) to operate, but may be absent when software is not required to operate.

[0225] This definition of circuit system applies to all uses of the term in this application, including in any claim. As another example, as used in this application, the term circuit system also covers only the implementation of hardware circuitry or processors and their accompanying software and / or firmware. For example, if applicable to a particular claim element, the term circuit system also covers baseband integrated circuits for mobile devices, or similar integrated circuits in servers, cellular network devices, or other computing or networking devices.

[0226] Although specific terms are used in this article, they are used only in a general and descriptive sense, not for restrictive purposes.

[0227] The features described above can be used in combinations other than those explicitly described.

[0228] Although some features have been described with reference to certain characteristics, these functions can be performed by other features, whether or not they are described.

[0229] While features have been described with reference to certain examples, these features may also exist in other examples, whether or not they are described. Therefore, a feature associated with one example / aspect of the invention may include any or all features associated with another example or aspect of the invention, and vice versa, provided they do not contradict each other.

[0230] Although various examples of this disclosure have been described in the preceding paragraphs, it should be understood that modifications may be made to the given examples without departing from the scope of the invention as set forth in the claims.

[0231] The term 'comprise' as used in this document is inclusive rather than exclusive. That is, any reference to X that includes Y means that X may include only one Y or may include more than one Y. If the intention is to use 'comprise' with an exclusive meaning, it will be clearly stated in the context by referring to 'comprising only one' or using 'consisting'.

[0232] In this specification, 'connection,' 'coupling,' and 'communication,' and their derivatives, refer to operational connection / coupling / communication. It should be understood that any number or combination of intermediate components (including no intermediate components) may be present to provide direct or indirect connection / coupling / communication. Any such intermediate component may include hardware and / or software components.

[0233] As used herein, the term "determine" (and its grammatical variations) can include at least: calculating, processing, deriving, measuring, investigating, identifying, searching (e.g., searching in a table, database, or other data structure), confirming, etc. Furthermore, "determine" can include receiving (e.g., receiving information), retrieving / accessing (e.g., retrieving / accessing data in memory), obtaining, etc. Additionally, "determine" can include parsing, selecting, picking, building, reasoning, etc.

[0234] As used herein, descriptions of actions should also be considered as disclosing enabling, and / or causing, and / or controlling the action. For example, a description of the transmission of information should also be considered as disclosing enabling, and / or causing, and / or controlling the transmission of information. Similarly, for example, a description of a means of transmitting information should also be considered as disclosing at least one component or controller of the means that enables, and / or causes, and / or controls the means of transmitting information.

[0235] The term "component" as used in the specification and claims may refer to one or more individual elements configured to perform one or more corresponding functions, or it may refer to several elements performing such one or more functions. Furthermore, the functions recited in the claims may be performed by the same individual components or a combination of the same components. For example, the execution of such one or more functions may be caused in the device by a processor executing instructions stored in the device's memory.

[0236] Unless explicitly stated otherwise (unless the context requires otherwise), references to parameters (e.g., relaxed standard parameters) or parameter values ​​should be understood as referring to “indicator data,” “definition data,” or “representation data” for the relevant parameter / parameter value. Data may indicate the relevant parameter / parameter value in any way and may indicate the relevant parameter / parameter value directly or indirectly.

[0237] Various examples are referenced in this specification. Descriptions of features or functions associated with an example indicate that such features or functions exist in that example. The use of the terms 'example,' 'for example,' 'maybe,' or 'can' in the text indicates (whether explicitly stated or not) that such features or functions exist at least in the described example, whether or not they are described as examples, and that they may, but not necessarily, exist in some or all other examples. Therefore, 'example,' 'for example,' 'maybe,' or 'can' refers to a specific instance of a class of examples. An instance's properties can be properties of only that instance, properties of the class, or properties of subclasses of the class that include some, but not all, instances of that class.

[0238] In this specification, unless otherwise expressly stated, references to “a / an / the” [feature, element, component, part…] have an inclusive rather than exclusive meaning and should be interpreted as “at least one” [feature, element, component, part…]. That is, any reference to X that includes one (a) / the Y indicates that X may include only one Y or may include more than one Y, unless the context clearly indicates the opposite. If the exclusive meaning of 'a (a)' or 'the' is intended to be used, it will be clearly stated in the context. In some cases, 'at least one' or 'one or more' may be used to emphasize the inclusive meaning, but the omission of these terms should not be construed as inferring any exclusive meaning. As used herein, “at least one of the following: ” and “at least one of ” and similar wording (where the list of two or more elements is connected by “and” or “or”) means at least any one of these elements, or at least any two or more of these elements, or at least all of these elements.

[0239] The presence of a feature (or combination of features) in a claim is a reference to that feature or combination of features itself, as well as a reference to a feature (equivalent feature) that achieves substantially the same technical effect. Equivalent features include, for example, features that are variations and achieve substantially the same result in substantially the same manner. Equivalent features include, for example, features that perform substantially the same function in substantially the same manner to achieve substantially the same result.

[0240] In this specification, various examples are referenced, and adjectives or adjective phrases are used to describe the characteristics of the examples. Such descriptions of characteristics associated with examples indicate that the characteristic exists exactly as described in some examples and substantially as described in others.

[0241] In the foregoing description, the described apparatus may alternatively or additionally include an apparatus that, in some other examples, comprises a distributed apparatus system, such as a client / server apparatus system. In examples where the provided apparatus forms (or the method is implemented as) a distributed system, each apparatus forming a component and / or part of the system provides (or implements) one or more features that collectively implement the embodiments of this disclosure. In some examples, the apparatus is reconfigured by an entity other than its initial manufacturer to implement the embodiments of this disclosure by being provided with additional software, such as software downloaded by a user and deployed to the apparatus, which, when executed, causes the apparatus to implement the embodiments of this disclosure (such implementation is either entirely implemented by the apparatus or implemented as part of the apparatus system described above).

[0242] The foregoing description illustrates some examples of this disclosure; however, those skilled in the art will recognize possible alternative structures and methodological features that provide equivalent functionality to the specific examples of such structures and features described above, and for the sake of brevity and clarity, these alternative structures and features have been omitted from the foregoing description. Nevertheless, the foregoing description should be understood to implicitly include references to such alternative structures and methodological features that provide equivalent functionality, unless such alternative structures or methodological features are expressly excluded in the foregoing description of the examples of this disclosure.

[0243] While efforts have been made in the foregoing specification to draw attention to those features of particular importance in the examples of this disclosure, it should be understood that the applicant claims protection for any patentable features or combinations thereof mentioned above and / or shown in the accompanying drawings, whether or not they are specifically emphasized.

[0244] Examples in this disclosure and the appended claims can be appropriately combined in any manner that is readily apparent to a person skilled in the art. The terms "example," "in some examples," etc., used individually in the specification do not necessarily refer to the same example, nor are they mutually exclusive, unless so stated and / or unless it is readily apparent to a person skilled in the art from the specification. For example, a feature, structure, process, block, step, action, etc., described in one example may be included in other examples, but not necessarily.

[0245] Each claim is incorporated into the specification as further disclosure, and the claims are embodiments of this disclosure. Furthermore, while the claims herein are provided to include specific dependencies, it is contemplated that any claim may depend on any other claim, and any such alternative embodiments and their equivalents are also within the scope of this disclosure to the extent that any alternative embodiment may arise by combining, integrating, and / or omitting features of various claims and / or changing the dependencies of the claims.
