[0004] 3rd Generation Partnership Project (3GPP) technology includes user equipment (UE) cross link interference (CLI) measurements, which can enable network entities to avoid scheduling users on resources that are impaired due to CLI. In addition, such measurements can enable network entities to coordinate scheduling between neighboring cells, between evolved Node B (eNB) and next generation Node B (gNB), and between central units (CU) and distributed units (DU) to reduce any impact from harmful CLI between UEs. By default, scheduling decisions are performed by part of the medium access control (MAC) layer and are made independently for each cell.

[0026] 3GPP TS 38.300, Section 9.2.4, summarizes the NR UE Radio Resource Management (RRM) measurement model as Figure 1As shown. Specifically, in RRC_CONNECTED mode, the UE measures at least one beam of the cell and averages the measurement results, such as power values, to derive the cell quality. In doing so, the UE is configured to consider a subset of the detected beams. Filtering occurs at two different levels: at the physical layer to derive beam quality, and then at the RRC level to derive cell quality from multiple beams, such as layer 3 filtering. Similarly, for serving cells and non-serving cells, cell quality from beam measurements is derived in the same way. If the gNB configures the UE to do so, the measurement report can contain measurement results for the X best beams.

[0027] Several components of the RRM measurement model can be modified and extended to also apply to UE CLI measurements. For example, UE CLI measurements can be subject to both layer 1 (L1) and layer 3 (L3) filtering procedures, whereby the L3 filter coefficients are configured by the network via higher layer RRC signaling. The defined RRM measurement framework relies on the network configuring at least one RRM measurement object for the UE, where each object defines a measurement and corresponding reporting criteria. Reporting criteria can include A1, A2, .., A6 events, as well as other events.

[0028] 3GPP TS 38.213, section 5.2, summarizes the NR UE CSI measurement framework. Here, each reporting setting CSI-ReportConfig is associated with a single downlink bandwidth part (indicated by the higher layer parameter bwp-Id) given in the associated CSI-ResourceConfig used for channel measurement. In addition, this contains at least one parameter for one CSI reporting band: the codebook configuration, including codebook subset restrictions, time domain behavior, frequency granularity for channel quality indicator (CQI) and precoding matrix indicator (PMI), measurement restriction configuration, and CSI-related quantities to be reported by the UE, such as layer indication (LI), L1-reference signal received power (RSRP), CSI-RS resource indication (CRI), and SSB resource indication (SSBRI).

[0029] Regarding the high-level signaling of one or more CSI resource settings for channel and interference measurement, CSI-IM resources for interference measurement are described in subsection 5.2.2.4, non-zero power (NZP) channel state information-reference signal (CSI-RS) resources for interference measurement are described in subsection 5.2.2.3.1, and NZP CSI-RS resources for channel measurement are described in subsection 5.2.2.3.1. In addition, the reporting configuration for CSI can be aperiodic (using the physical uplink shared channel (PUSCH)), periodic (using the physical uplink control channel (PUCCH)), or semi-persistent (using PUCCH, and PUSCH activated by downlink control information (DCI)). CSI-RS resources can also be periodic, semi-persistent, or aperiodic.

[0030] For CSI reporting, the UE can configure one of two possible subband sizes via higher layer signaling, where a subband is defined as contiguous PRBs and is based on Figure 2 The table disclosed in depends on the total number of PRBs in the bandwidth part. It is worth noting that the reportFreqConfiguration contained in CSI-ReportConfig indicates the frequency granularity of the CSI report. In the case of UE CLI measurement / reporting, the UE measures the instantaneous received power (expressed as Layer 1 (Ll)-RSRP) from its serving cell, the UE can be configured to measure the experienced co-channel interference, and the measurement can be wideband (carrier bandwidth or sub-bandwidth (BWP)) or per sub-band frequency selective.

[0031] As described above, UE CLI measurements come in the form of received signal strength indicator (RSSI) or sounding reference signal (SRS)-reference signal received power (RSRP) measurements and are subject to L3 filtering by default. However, there is a lack of details about L3 filtering and reporting events and related means for UE CLI measurements. In addition, there is currently no technology on how to configure SRS-RSRP measurement reports and CLI-RSSI measurement reports together for UEs. There is a need in the art to improve filtering and reporting of UE CLI measurements.

[0032] Certain example embodiments described herein may have various benefits and / or advantages that overcome the above-described shortcomings. Certain example embodiments described below may provide semi-dynamic information of UE CLI experience to the network with limited complexity. For example, the network may use such information for scheduling decisions per cell, as well as for semi-dynamic coordination between cells (or gNBs). For example, this information may enable alignment of radio frame configurations to reduce the impact from UE-2-UE CLI. In addition, certain example embodiments provide faster and more accurate UE CLI information to the network at the same rate as UE CSI measurements, enabling the network to provide faster scheduling decisions. Such information provides rapid adaptation and improved response to bursty CLI compared to bursty transmissions that may interfere with UE transmissions.

[0033] Furthermore, certain example embodiments with subband-based UE CLI measurement / reporting may provide networks with enhanced possibilities to benefit from frequency domain scheduling, for example, by avoiding scheduling UEs in subbands where they experience harmful UE-2-UE CLI conditions. Furthermore, certain example embodiments described herein do not impose additional signaling overhead in terms of CQI masking, since the CQI is already reported. As a further result, signaling overhead may be reduced, and reliability and latency may be improved. Therefore, certain example embodiments relate to improvements in computer-related technologies.

[0034] Figure 3 FIG. 3 shows a signaling diagram associated with RRC according to some example embodiments. The network entity 310 may be similar to Figure 5 The network entity 510 in FIG. 1 and the user equipment 320 may be similar to Figure 5 301 , NE 310 may send at least one message to UE 320. In some example embodiments, at least one message may include at least one CLI measurement framework object such as CLImeasObject, which may be configured to add a new CLImeasObject, remove an existing CLImeasObject, and / or modify an existing CLImeasObject. UE 320 may have zero, one, or more configured CLImeasObject parameters.

[0035] In certain example embodiments, at least one CLI measurement framework object may be itemized as a received signal strength indicator (RSSI) or a sounding reference signal-reference signal received power (SRS-RSRP). As an example, a corresponding SRS configuration that the UE 310 may use to measure the SRS-RSRP may be included in the SRS-RSRP.

[0036] In some example embodiments, at least one CLI measurement framework object may include at least one L3 filter parameter represented as a filter coefficient in an infinite impulse response (IIR) filter, or an equivalent time domain averaging time.

[0037] In various example embodiments, at least one CLI measurement framework object may include at least one reporting event condition, which may be periodic or event-triggered. For example, for an event-triggered reporting event condition, at least one UE CLI measurement may be reported when it exceeds a certain predefined threshold. Additionally or alternatively, at least one UE CLI measurement may be reported when the UE CLI measurement exceeds a certain level compared to the RSRP measured by the UE from its serving cell and / or the interference experienced by the UE. In some example embodiments, the value of at least one threshold value may be part of at least one measurement framework object such as CLImeasObject. If the report is a function of the interference experienced by the UE, the measurement framework object may include information about whether the interference is based on a simple RSSI, and / or based on, for example, at least one CSI interference measurement (CSI-IM) resource and / or non-zero power (NZP) CSI-RS resource for interference measurement.

[0038] In certain example embodiments, the at least one CLI measurement framework object may be at least one report type. For example, the at least one CLI measurement framework object may be a CLI warning message, which may simply indicate that a triggering criterion has been met. Additionally or alternatively, the at least one CLI measurement framework object may include at least one actual measurement value of the UE CLI measurement, which may be expressed in dBm, and other potential measurements such as the UE's serving cell RSRP.

[0039] In some example embodiments, at least one CLI measurement framework object may be associated with RRC signaling in accordance with 3GPP TS 38.331 (RRC signaling). For example, RRC signaling may define at least one PHY / MAC procedure for CLI reporting. Such information may define whether the UE should return UE CLI measurements / information to the network using implicit or explicit signaling, and whether the UE CLI measurements should be wideband or per subband.

[0040] In various example embodiments, at least one CLI measurement framework object may be associated with PHY level reporting of UE CLI, as described in 3GPP TS 38.213. For example, at least one CLI measurement framework object may include criteria defining when UE CLI measurements become greater than a predefined threshold relative to UE interference measurements. In addition, if the measured CLI is above at least one predefined threshold, the UE may employ implicit signaling of UE CLI measurements by configuring the CQI report to be "null" or "zero". In certain example embodiments, UE CLI reporting included in a MAC-CE may be performed.

[0041] At 303, in response to receiving at least one RRC-based CLI measurement framework object, UE 320 may determine whether a triggering criterion for at least one received UE CLI measurement object has occurred. At 305, UE 320 may send at least one UE CLI measurement to NE 310, for example, as part of at least one RRC message (such as a CLI warning message). In some example embodiments, the at least one UE CLI measurement may indicate that the triggering criterion has been met, an actual measurement value of the UE CLI measurement (e.g., expressed in dBm), the UE's serving cell RSRP, and / or other potential measurements.

[0042] At 307, in response to receiving and analyzing at least one UE CLI measurement, NE 310 may take at least one action. For example, NE 310 may take at least one action to resolve inter-UE CLI issues on a semi-dynamic time scale based on the reporting rate of the RRC measurements and / or the desired behavior. RRC messages may be sent only at a medium rate, for example, every 20-100 ms.

[0043] Figure 4 FIG. 4 shows a signaling diagram associated with PHY / MAC according to certain example embodiments. The network entity 410 may be similar to Figure 7 The network entity 710 in FIG. 4 and the user equipment 420 may be similar to Figure 7 The user device 720 in FIG. 4 and the user device 420 may be similar to Figure 7 401 , NE 410 may send at least one message to UE 420. In some example embodiments, at least one message may configure UE 420 to measure CLI (such as RSSI or SRS-RSRP) and / or UE interference measurements, such as those based on CSI-IM resources or NZP CSI-RS resources for interference measurements. For example, such measurements may be configured as wideband or such as per-subband frequency selective.

[0044] At 403, UE 420 may determine that at least one UE CLI measurement, such as SRS-RSRP, becomes greater than at least one network configured threshold relative to at least one UE interference measurement. Thus, UE 420 may determine that at least one CLI problem exists.

[0045] At 405, UE 420 may send at least one message with at least one indication of at least one detected CLI problem to NE 410. For example, the at least one indication may be a Boolean indication, such as an indication included in at least one CLI warning message, and / or may be sent as a fast physical layer message (e.g., on PUCCH or PUSCH) or as a MAC-CE.

[0046] In some example embodiments, if at least one UE CLI and / or UE interference measurement is configured as per subband measurement, then at least one CLI warning message may be represented as at least one vector of Boolean values, where each element may correspond to at least one of the subbands.

[0047] In various example embodiments, UE 420 may employ implicit signaling of at least one UE CLI measurement, for example, by setting at least one CQI reporting parameter to "null" or "zero" if the CLI is measured to be above at least one predetermined threshold. In addition, at least one implicit signal of at least one CLI warning message may depend on whether the CSI / CQI is configured as wideband or per subband. As a result, this will not require additional signaling overhead while still sending information to NE 410 about when the UE should not be scheduled when experiencing a CLI level exceeding at least one predefined threshold. For example, NE 410 may not schedule the UE when associated with a "null" or "zero" CQI value.

[0048] In certain example embodiments, when UE 420 notifies NE 410 about CLI, NE 410 may allocate UL resources so that UE 420 may send a detailed CLI measurement report such as a PHY / MAC / RRC mixed one.

[0049] Figure 5 It is shown that by Figure 7An example of a method performed by a NE of NE710 in FIG. 501. At 501, a network entity may send at least one message to a user equipment. In some example embodiments, the at least one message may include at least one CLI measurement framework object such as CLImeasObject, which may be configured to add a new CLImeasObject, remove an existing CLImeasObject, and / or modify an existing CLImeasObject. The user equipment may have zero, one, or more configured CLImeasObject parameters.

[0050] In certain example embodiments, at least one CLI measurement framework object may be itemized as a received signal strength indicator (RSSI) or a sounding reference signal-reference signal received power (SRS-RSRP). As an example, a corresponding SRS configuration that a user equipment may use to measure SRS-RSRP may be included in the SRS-RSRP.

[0051] In some example embodiments, at least one CLI measurement framework object may include at least one L3 filter parameter expressed as a filter coefficient in an infinite impulse response (IIR) filter, or an equivalent time-domain averaging time.

[0052] In various example embodiments, at least one CLI measurement framework object may include at least one reporting event condition, which may be periodic or event triggered. For example, for an event triggered reporting event condition, at least one UE CLI measurement may be reported when a certain predefined threshold is exceeded. Additionally or alternatively, at least one UE CLI measurement may be reported when the UE CLI measurement exceeds a certain level compared to the RSRP measured by the UE from its serving cell and / or the interference experienced by the UE. In some example embodiments, the value of at least one threshold may be part of at least one measurement framework object such as CLImeasObject. If the report is a function of the interference experienced by the UE, the measurement framework object may include information about whether the interference is based on a simple RSSI, and / or based on, for example, at least one CSI interference measurement (CSI-IM) resource and / or non-zero power (NZP) CSI-RS resource used for interference measurement.

[0053] In certain example embodiments, the at least one CLI measurement framework object may be at least one report type. For example, the at least one CLI measurement framework object may be a CLI warning message, which may simply indicate that a triggering criterion has been met. Additionally or alternatively, the at least one CLI measurement framework object may include at least one actual measurement value of the UE CLI measurement, which may be expressed in dBm, and other potential measurements such as the UE's serving cell RSRP.

[0054] In some example embodiments, at least one CLI measurement framework object may be associated with RRC signaling in accordance with 3GPP TS 38.331 (RRC signaling). For example, RRC signaling may define at least one PHY / MAC procedure for CLI reporting. Such information may define whether the UE should return UE CLI measurements / information to the network using implicit or explicit signaling, and whether the UE CLI measurements should be wideband or per subband.

[0055] In various example embodiments, at least one CLI measurement framework object may be associated with PHY level reporting of UE CLI as described in 3GPP TS 38.213 (CLI Warning Message). For example, at least one CLI measurement framework object may include criteria defining when UE CLI measurements become greater than a predefined threshold relative to UE interference measurements. In addition, if the CLI is measured above at least one predefined threshold, the UE may employ implicit signaling of UE CLI measurements by configuring the CQI report to be "null" or "zero". In addition, UE CLI reporting associated with MAC-CE may be performed as described in 3GPP TS 38.324.

[0056] At 503, the network entity may receive at least one UE CLI measurement, e.g., as part of at least one RRC message (such as a CLI warning message). In some example embodiments, the at least one UE CLI measurement may indicate that a triggering criterion has been met, an actual measurement value of the UE CLI measurement (e.g., expressed in dBm), a serving cell RSRP of the UE, and / or other potential measurements.

[0057] At 505, in response to receiving at least one report message, the network entity may take at least one action. For example, the network entity may take at least one action to resolve at least one inter-UE CLI issue on a semi-dynamic time scale based on at least one report rate and / or desired behavior associated with the RRC measurement. RRC messages may be sent only at a medium rate, such as every 20-100 ms.

[0058] Figure 6 It is shown that by Figure 7 An example of a method performed by a NE of NE710 in . At 601, a network entity may send at least one message to a user equipment. In some example embodiments, the at least one message may configure the user equipment to measure CLI (such as RSSI or SRS-RSRP) and / or UE interference measurements, such as those based on CSI-IM resources or NZP CSI-RS resources. For example, such measurements may be configured as wideband or such as per subband frequency selective.

[0059] At 603, the network entity may receive at least one message from the user equipment with at least one indication of at least one detected CLI problem. For example, the at least one indication may be a Boolean indication, such as an indication included in at least one CLI warning message, and / or may be sent as a fast physical layer message (e.g., on PUCCH or PUSCH) or as a MAC-CE.

[0060] In some example embodiments, if at least one UE CLI and / or UE interference measurement is configured as per subband measurement, then at least one CLI warning message may be represented as at least one vector of Boolean values, where each element may correspond to at least one of the subbands.

[0061] In certain example embodiments, when the user equipment notifies the network entity about the CLI, the network entity may allocate UL resources so that the user equipment may send a detailed CLI measurement report, such as a PHY / MAC / RRC hybrid.
