Description

Technical Field

[0001] This disclosure relates to the field of wireless communications. Specifically, it relates to methods and related apparatus for processing transmissions between a radio network node and a wireless device (WD), such as the associated radio network node and the associated WD. Background Technology

[0002] In the 3rd Generation Partnership Project (3GPP) New Radio (NR), operations such as Virtual Reality (VR), Augmented Reality (AR), and Extended Reality (XR) cloud gaming are already supported. These types of operations are typically sensitive to latency and require high data rates. In addition to performing such data transmission / reception processes between the WD and radio network nodes (e.g., base stations), the WD is also required to perform cell measurements to ensure that the WD attaches to or connects to the most suitable cell. Measurements can be triggered and / or performed periodically, for example, to determine if the signal quality of the serving cell has deteriorated. When the signal quality falls below a certain threshold, the WD is configured to initiate neighboring cell measurements to initiate a handover from the serving cell. During the measurement period, the WD is prevented from performing data transmission and / or reception, which increases the latency of data transmission. This can, for example, impair the quality of service for XR applications due to interrupted and / or delayed data transmission / reception. Summary of the Invention

[0003] Therefore, there is a need for apparatus and methods for processing transmissions between radio network nodes and WD, which can mitigate, alleviate or resolve existing drawbacks and provide reduced transmission latency.

[0004] A method for handling transmissions between a radio network node and a wireless device (WD), performed by a radio network node, is disclosed. The method includes transmitting to the WD a configuration of a measurement gap for the WD to perform signal quality measurements. The method includes obtaining an indication of a conflict between an upcoming data transmission and the configured measurement gap. The method also includes transmitting to the WD information indicating a temporary modification to the configured measurement gap.

[0005] Furthermore, a radio network node is provided. This radio network node includes memory circuitry, processor circuitry, and a wireless interface, wherein the radio network node is configured to perform any of the methods disclosed herein.

[0006] An advantage of this disclosure is that a radio network node can be enabled to temporarily modify the WD's configured measurement intervals to allow the WD to transmit and / or receive data during the configured measurement intervals. This allows latency-sensitive and / or delay-sensitive data transmissions to take precedence over performing signal quality measurements within the configured measurement intervals. By prioritizing data transmissions, such as configuring the WD to transmit and / or receive data fully or partially within the configured measurement intervals, latency for data transmission can be reduced because data transmission does not have to be interrupted to allow the WD to perform signal quality measurements within the configured measurement intervals. By reducing latency, the risk of data loss (such as video frames transmitted in XR) can be reduced, which increases the quality of data transmission.

[0007] A method executed by a WD (Wireless Drive) is disclosed for processing transmissions between the WD and a radio network node. The method includes receiving from the radio network node a configuration of a measurement gap set by the WD to perform signal quality measurements. The method also includes receiving from the radio network node information indicating temporary modifications to the configured measurement gap.

[0008] Furthermore, a WD is provided. The WD includes memory circuitry, processor circuitry, and a wireless interface, wherein the WD is configured to perform any of the methods disclosed herein.

[0009] An advantage of this disclosure is that the WD can be configured to temporarily avoid performing signal quality measurements during a configured measurement interval, instead transmitting and / or receiving data during the configured measurement interval. This allows time-sensitive and / or latency-sensitive data transmission to take precedence over performing signal quality measurements during the configured measurement interval. By prioritizing data transmission and / or reception, such as transmitting and / or receiving data fully or partially within a configured measurement interval, the latency of data transmission can be reduced because data transmission does not have to be interrupted to allow the WD to perform signal quality measurements during the configured measurement interval. By reducing latency, the risk of data loss (such as video frames transmitted in XR) can be reduced, which increases the quality of data transmission. Attached Figure Description

Detailed Implementation

[0011] Various examples and details are described below with reference to the accompanying drawings (where applicable). It should be noted that the drawings may or may not be drawn to scale, and throughout the drawings, elements with similar structures or functions are indicated by the same reference numerals. It should also be noted that the drawings are intended only to facilitate the description of examples. They are not intended as an exhaustive description of this disclosure or as a limitation on the scope of this disclosure. Furthermore, the illustrated examples need not possess all the aspects or advantages shown. Aspects or advantages described in connection with a particular example are not necessarily limited to that example and may be practiced in any other example, even if not so stated or explicitly described.

[0012] The accompanying drawings are schematic and simplified for clarity, and they only show details that aid in understanding this disclosure, while other details have been omitted. Throughout the text, the same reference numerals are used for the same or corresponding components.

[0013] Figure 1This is a diagram illustrating an example wireless communication system 1 according to the present disclosure, including an example radio network node 400, an example wireless device 300, and a core network (CN) 600 node.

[0014] As discussed in detail herein, this disclosure relates to a wireless communication system 1 that includes a cellular system (e.g., a 3GPP wireless communication system).

[0015] The radio network node disclosed herein refers to a radio access network (RAN) node operating in a radio access network, such as a base station, evolved Node B, eNB, or gNB in ​​an NR. In one or more examples, a RAN node is a functional unit that can be distributed across several physical units.

[0016] The CN node disclosed in this document refers to a network node operating in the core network, such as a network node operating in the Evolved Packet Core (EPC) and / or the 5G Core Network (5GC). Examples of CN nodes in the EPC include the Mobility Management Entity (MME).

[0017] The wireless communication system 1 described herein may include one or more wireless devices 300, 300A and / or one or more network nodes 400, such as one or more base stations, eNBs, gNBs and / or access points.

[0018] Wireless devices can refer to mobile devices and / or user equipment (UE).

[0019] Wireless devices 300 and 300A can be configured to communicate with network node 400 via wireless link (or radio access link) 10 and 10A. CN 600 can be configured to communicate with network node 400 via wireless link (or radio access link) 12.

[0020] In the 3rd Generation Partnership Project (3GPP) New Radio (NR), wireless communication systems can be configured to support extended reality (XR) applications, such as virtual reality (VR), augmented reality (AR), and / or cloud gaming.

[0021] Extended Reality (XR) and cloud gaming refer to different types of augmented, virtual, and hybrid environments where human-to-machine and human-to-human communication is performed with the assistance of wireless devices such as handheld and / or wearable end-user devices (UEs). XR and cloud gaming are considered two important applications for NR Release 18 and above, also known as Advanced 5G. Therefore, some new features of 5G New Radio (NR) supporting Extended Reality (XR) have been added as part of 3GPP Release 18.

[0022] XR traffic is rich in video, especially in the downlink, with a typical frame rate of 60Hz. Some applications may require higher frame rates, such as 90Hz or 120Hz. This results in data transmission with non-integer periods in NR. In other words, the data transmission period is not an integer number of subframes. In this example, the period is 16.67 ms. Due to varying frame coding delays and network delivery times, packets arriving at radio network nodes can experience random jitter. This is described in 3GPP Technical Report (TR) 38.838 v.17.0.0. Figure 5 .1.1-1 shows the frame rate and jitter of DL traffic. The non-integer and jitter characteristics of XR traffic are referred to as quasi-periodic traffic.

[0023] In addition to performing data transmission and reception, the WD (Driver) is required to perform cell measurements. For example, if the signal quality of the serving cell is deteriorating, such as falling below a certain signal quality threshold, the WD can begin neighboring cell measurements to find cells with better signal quality than the serving cell. The serving cell can be considered in this context as the cell responsible for establishing and maintaining radio connections with the WD in the control plane. To determine signal quality, the WD may have to measure neighboring cell signals. Measurements can also be performed at the same carrier frequency (intra-frequency measurement) or different carrier frequencies (inter-frequency measurement) of the serving cell. To reduce the WD's manufacturing cost and / or form factor, the WD may have a single radio frequency (RF) module. The WD may therefore have to use a single RF module to perform measurements as well as data transmission and reception.

[0024] When cells, such as the serving cell and neighboring cells, transmit on the same frequency, the WD can perform measurements on signals transmitted from the neighboring cell while simultaneously transmitting and receiving data from the serving cell (i.e., intra-frequency measurement). However, if cell measurements and data transmission and / or reception are performed in different bandwidth portions (but still on the same carrier frequency), the WD must suspend data transmission / reception when required to perform measurements. In another example, if a neighboring cell operates on a different frequency than the serving cell (which may be referred to as the serving cell being an inter-frequency neighbor), and / or uses a different Radio Access Technology (RAT) (such as LTE when the serving cell is operating with 5G NR), the WD must suspend communication with the serving cell (such as transmitting (Tx) to and / or receiving (Rx) from the serving cell) and needs to tune its RF module to the neighboring cell's configured frequency (which may be referred to as configured measurement objects) and restore connection with the serving cell after a certain duration. This is called inter-frequency measurement. If other cells are using other wireless communication systems, the measurement is called inter-RAT measurement.

[0025] The duration during which a WD suspends its communication with the serving cell to perform measurements on inter-frequency neighbors or other RAT neighbors may be referred to herein as a measurement gap.

[0026] Figure 2 The diagram illustrates a measurement operation using one or more measurement gaps 20. During a measurement gap 20, the WD can perform cell signal measurements based on the synchronization signal (SS) and physical broadcast channel (PBCH) included in the SS / PBCH block (SSB). SSBs can be transmitted in bursts, which can be considered here as batches, such as multiple SSBs. The number of SSBs in a burst depends on the operating frequency. If the operating frequency (fc) is < 3 GHz within frequency range 1 (FR1), the number of SSBs in a burst is typically 4; for fc = 3 GHz to 6 GHz in FR1, the number of SSBs in a burst is typically 8; and for fc > 6 GHz, such as for millimeter waves, the number of SSBs in a burst is typically 64. The period of the SSB can be configured for each cell within the range of 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, or 160 ms. However, the WD does not need to measure cell signals with a period as frequent as the period of the SSBs. The period for measuring cell signals can be referred to here as the measurement period. The appropriate measurement cycle for WD can be configured based on channel conditions. This is necessary and can help avoid unnecessary measurements and reduce power consumption on the mobile device (UE).

[0027] 3GPP specifications, such as TS 38.331 v18.0.0, have introduced a SSB-based Radio Resource Management (RRM) measurement timing configuration window (called the SMTC window). The network (e.g., a radio network node) can inform the WD about the measurement period, such as the Measurement Interval Repetition Period (MGRP) and timing of the SSBs that the WD can and / or will use for measurement. The SMTC window period can be set within the same range as the SSB period, such as 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, or 160 ms. Depending on the number of SSBs transmitted on the cell being measured, the duration of the SMTC window can be set to 1 ms, 2 ms, 3 ms, 4 ms, or 5 ms. The duration of the SMTC window can be chosen to be large enough to accommodate all SSBs transmitted from the serving cell and / or neighboring cells.

[0028] Measurement gap 20 can be used to measure reference signals (such as SSBs) from multiple spatial filters (such as beam directions) from a cell, here numbered SSB#1 to SSB#4. Each measurement gap 20 may include SSBs from multiple spatial filters, referred herein as SSB#1 from a first spatial filter, SSB#2 from a second spatial filter, SSB#3 from a third spatial filter, and SSB#4 from a fourth spatial filter. SSBs from other cells (e.g., overlapping) may exist within the SMTC window. Measurement gap 20 may have a time length, such as duration, referred herein as measurement gap length (MGL). Measurement gaps may include the SMTC window. MGL may be greater than the SMTC window length to allow the WD to retune its RF module to the operating frequency and / or RAT of a neighboring cell before the start of the SMTC window (such as the start of an SSB burst). In other words, the measurement gap may include retuning time before and / or after the SMTC window to allow the WD to tune its RF module to an upcoming transmission. Radio network nodes can set the SMTC window length and measurement gap length based on the period of SSB bursts from nearby measObjects, such as neighboring cells.

[0029] In 3GPP 5G NR, as described in 3GPP TS 38.331 v.18.0.0, measurement gap configuration can be provided to the WD via Radio Resource Control (RRC) signaling. Measurement gap configuration can be provided using the MeasGapConfig information element (IE) within the MeasConfig IE. The MeasConfig IE and / or MeasGapConfig IE can be carried by an RRC reconfiguration message. The RRC reconfiguration message can have two parts. The first part of the RRC reconfiguration message can specify the control setting and / or release of the measurement gap. The second part of the RRC reconfiguration message can specify the measurement gap configuration and control the setting and / or release of the configured measurement gap. Details of an example MeasGapConfig IE are shown below:

[0030] in: - mgrp is the measurement interval repetition period and defines the period (in ms) during which the measurement interval is repeated. mgrp can be configured to 20 ms, 40 ms, 80 ms and / or 160 ms.

[0031] - `gapOffset` indicates the offset of the measurement gap pattern, such as the offset between two subsequent measurement gaps. Approximately 160 offset values ​​may be available for `gapOffset`; however, not all values ​​may be applicable to all mgRP periods. The offset value can point to the starting subframe within the period. The offset value can range from 0 to mgRP-1. For example, if the mgRP period is 20 ms, the gap offset can range from 0 to 19 ms.

[0032] - mgl is the measurement gap length and is defined in milliseconds (ms). mgl can be 1.5 ms, 3 ms, 3.5 ms, 4 ms, 5.5 ms, and / or 6 ms.

[0033] - mgta is the measurement gap timing advance and is defined as the start of the measurement performed by the WD before the occurrence of the first subframe of the measurement gap. When mgta is configured, the WD begins measuring mgta N ms before the occurrence of the gap subframe. N is the configured mgta value. In other words, the start of the measurement gap is advanced by N ms relative to the end time of the latest subframe that immediately precedes the measurement gap. For frequency range 2 (FR2), the timing advance can be 0.25 ms, or for FR1 it can be 0.5 ms.

[0034] In 5G NR, the measurement gap length is not fixed but configurable by the network. Having a fixed measurement gap can lead to unnecessary degradation of throughput in the serving cell. The SMTC window and window duration can be set to match SSB transmissions and, correspondingly, MGL. For example, assuming an SMTC window duration of 2 ms and a measurement gap length of 6 ms, there is a 4 ms segment that cannot be used for data transmission and reception in the serving cell, resulting in reduced downlink (DL) and / or uplink (UL) throughput.

[0035] Current 5G NR specifications allow networks to configure a search threshold (s-MeasureConfig) for the WD in RRC connectivity mode, thereby reducing in-frequency measurement workload. For example, 3GPP TS 38.331 v18.0.0 defines the parameter s-MeasureConfig. The s-MeasureConfig parameter is a threshold for NR secondary primary cell (SpCell) RSRP measurement control, which controls when the WD needs to perform measurements on neighboring cells. Measurements can be based on the cell RSRP of the SS / PBCH block (here referred to as ssb-RSRP) or on the cell RSRP of the Channel State Information Reference Signal (CSI-RS) (here referred to as csi-RSRP).

[0036] If the network is configured with an s-MeasureConfig threshold that allows the WD to avoid performing measurements on non-serving cells (including in-frequency neighboring cells), there may be unused scheduling opportunities if the WD avoids performing in-frequency measurements. However, the current network is unaware of this and therefore adheres to the defined scheduling constraints.

[0037] Figure 3 The diagram illustrates an example measurement model operation at the WD according to the legacy operation defined in 3GPP TS 38.331. According to TS 38.300 Clause 9.2.4 v18.0.0, the WD performs multiple filtering operations on signal quality measurements, including Layer 1 (L1) filtering and Layer 3 (L3) filtering. When the WD is in the RRC_CONNECTED state, the WD measures multiple beams of the cell (such as at least one), and the measurement results (such as power values) are averaged to derive cell quality, such as the cell's signal quality. In doing so, the WD is configured to consider a subset of the detected beams and may filter other beams. Filtering occurs at two different levels, e.g., at L1 (physical layer) to derive beam quality, and then at L3, e.g., the RRC level, to derive cell quality from multiple beams. L1 measurements are typically used in processes that may require actions with minimal delay, such as beam management processes. For example, when the WD is required to change beams rapidly. L3 measurements are typically used for radio resource management decisions. This process may require long-term observation of channel conditions. For example, triggering a handover process based on Layer 3 filtering. The WD collects multiple measurement reports across multiple timings and multiple beams. The beams can be transmitted in one or more cells, such as the serving cell and / or one or more neighboring cells. The WD can then perform filtering based on these multiple measurement reports and subsequently send the filtered reports to the network, such as to radio network nodes. These filtering operations are necessary to ensure that reliable measurement reports are being reported by the WD. Parameters to be used for filtering can be provided to the WD via RRC signaling from the radio network nodes.

[0038] In traditional 5G NR, the data delivery controller (WD) has scheduling constraints that preclude it from transmitting and / or receiving during measurement gaps. During measurement gaps, the WD is expected to perform RRM operations, such as measuring the Reference Signal Received Power (RSRP) of received SSBs (e.g., SSBs received from the serving cell and / or neighboring cells). Measurement gaps can occur simultaneously with resources (such as configured licenses) already allocated to the WD for data transmission (Tx) and / or reception (Rx). Figure 4 An example of this situation is shown, where the authorization (CG) for the configuration of data transmission (e.g., for XR traffic) conflicts with the measurement gap 20 in time, such as during the MGL of the measurement gap 20, as... Figure 4The dashed box in the diagram illustrates this. CG can be considered in this paper as a periodically recurring resource that can be pre-allocated to WD for data transmission. Conventional scheduling constraints can affect XR transmissions because WD may be unable to transmit and / or receive XR application-related data during MGL, potentially leading to a degradation in the Quality of Service (QoS) of the XR application. XR applications are sensitive to latency and / or waiting time, and this can be referred to herein as waiting time-sensitive and / or latency-sensitive data transmission and / or reception. In this paper, waiting time-sensitive and / or latency-sensitive are used interchangeably. For simplicity, when referring to both waiting time-sensitive and / or latency-sensitive data transmission and / or reception, waiting time-sensitive data transmission will be used hereinafter. Therefore, large latency can delay the transmission of video frames. Delayed video frames may be outdated or unavailable, and may even be dropped at higher layers, such as in the RAN domain, at the Packet Data Convergence Protocol (PDCP) level, and / or at the application layer. Therefore, delayed video frames can cause applications such as XR or cloud gaming applications to lag. In other words, waiting time-sensitive data transmission requires low latency to ensure no data loss during transmission.

[0039] This disclosure provides a solution to overcome the potential limitations of measurement gap configuration on data traffic (particularly XR traffic) by adding functionality that allows dynamic adjustment of the measurement gap. Since data transmission in XR applications is time-sensitive, this disclosure proposes a mechanism that enables the network to provide the WD with information instructing the WD to perform and / or continue data transmission and / or reception during the measurement gap period. This mechanism can be supported by one or more of the following operations: In one or more example methods, such as Figure 5 In the example method shown, the network (such as a radio network node) instructs the WD that the WD may temporarily modify the configured measurement gap 20. Figure 5 In the example shown, the network can instruct the WD to skip (or, as can be referred to here, to block) the RRM measurement in measurement gap 20, which potentially conflicts with the CG of the data traffic, such as for... Figure 5 The second measurement gap timing and the third CG, as indicated by the dashed frame. The measurement gap to be skipped is determined by... Figure 5The circle X in the diagram represents a radio network node. The radio network node indicator here can be considered as a radio network node that provides information indicating temporary modifications to the configuration of the measurement gap. It is expected that the WD will resume measurement at a subsequent measurement gap timing that does not conflict with the CG. In one or more example methods, the indication can be provided before or during the measurement gap timing. The indication can be provided before the measurement gap when the measurement and data transmission are in different bandwidth portions, for example, for inter-frequency measurements. When the measurement and data transmission are within the same bandwidth portion (e.g., for intra-frequency measurements), the indication can be provided during the measurement gap.

[0040] In one or more example methods, the indication may be provided to the WD from a radio network node via low-layer signaling such as downlink control signaling (DCI) or via media access control (MAC) control element (CE) signaling. In one or more examples, the indication (such as information indicating temporary modification of the signal) may include an indication to skip and / or release measurement gap timings and / or to perform data transmission and / or reception during measurement gap timings. The indication may be provided just before the measurement gap timing.

[0041] Figure 6 The diagram illustrates a measurement operation according to one or more example methods described herein, where a radio network node may instruct a WD that the WD will perform a partial measurement during a measurement gap opportunity. In one or more example methods, this can be performed by providing (such as configuring) a virtual measurement gap 20A. A virtual measurement gap can be considered as a temporary measurement gap within a configured measurement gap that is valid for one or more selected measurement gap opportunities. A virtual measurement gap may be valid for a finite amount of time, such as for a finite number of measurement gap opportunities. Therefore, a virtual measurement gap may temporarily take precedence over the configured measurement gaps to enable data transmission and / or reception within a subset of the configured measurement gaps (such as within a subset of the resources allocated to the configured measurement gaps). A virtual measurement gap can therefore be considered a sub-gap of a configured measurement gap. A virtual measurement gap may have a virtual MGL within a pre-configured MGL. The virtual MGL may be shorter than the pre-configured MGL and therefore may be a subset of the pre-configured MGL. This can be applied, for example, to situations where the CG for data Tx / Rx partially conflicts with measurement gap 20, e.g. Figure 6The second MGL and third CG are shown and indicated by dashed frames. In one or more examples, the indication (such as information indicating temporary modification of the signal) may include an indication of performing data transmission and / or reception during the measurement gap timing. In one or more example methods, the indication, such as information indicating temporary modification, may include the actual location of the virtual measurement gap. The actual location of the virtual measurement gap may, for example, be indicated as a sub-section of the measurement gap. In one or more example methods, the indication of the actual location of the virtual measurement gap includes a time offset value, such as a time offset relative to the start point of the conventional measurement gap timing. The granularity of the time offset may, for example, be at the Orthogonal Frequency Division Multiplexing (OFDM) symbol level. In one or more example methods, the indication of the actual location of the virtual measurement gap includes the length of the virtual measurement gap. The granularity of the length of the virtual measurement gap may be at the OFDM symbol level. In one or more example methods, one or more parameters of the indication, such as the length of the virtual measurement gap, the actual location of the virtual measurement gap, and the time offset value, are provided via higher-layer signaling (such as via RRC). In one or more example methods, the length of the virtual measurement gap is provided via higher-level signaling, while the time offset value is provided as lower-level signaling, such as via DCI or MAC CE signaling.

[0042] The WD performing measurement gap release and / or partial measurement may have separate (such as dedicated) L3 filtering operations. For example, it may be configured with its own parameters, such as dedicated filter coefficients, to update the L3 beam filter to include information about beams that have not yet been measured, such as those that have been released and / or skipped.

[0043] In one or more example methods, a radio network node sends a message to the WD including an indication to enable and / or disable data transmission during measurement gaps. The message including the indication can be signaled using WD-specific signaling. This can be a fallback option, primarily because skipping configured measurement gaps can affect measurement operations. If skipping the operation provides negative effects, a fallback option should be available, such as when providing a signal to disable and / or terminate the operation. Subsequently, the radio network node may send another message including an indication to reactivate the operation.

[0044] In one or more example methods, the radio network node and / or the WD exchange information relating to their ability to perform measurement gap skipping and / or partial measurement gap operations. In one or more example methods, the exchanged information includes the radio network node instructing the WD whether it supports features such as whether the radio network node supports allowing the WD to perform data transmission and / or reception during the measurement gap. In one or more example methods, the exchanged information includes the WD instructing itself on its ability to perform data transmission and / or reception during the measurement gap, such as its ability to skip and / or release the measurement gap and / or its ability to perform partial measurements (such as performing measurements in a virtual measurement gap).

[0045] In one or more example methods, such as when scheduled data is in the DL, the radio network node knows the priority of the DL data transmission and can indicate to the WD whether skipping the measurement gap is feasible and the duration of the skip based on the priority of the DL data transmission.

[0046] In one or more example methods, such as when the scheduled data is in the UL, or when data transmission is time-critical XR gesture control, the WD may instruct the radio network node that it will use all or part of the SMTC measurement window for data transmission instead of performing measurements to prioritize UL traffic. This can be indicated in a scheduling request (SR) that includes one or more additional parameters. The additional parameters instruct the network node to request uplink resources for UL wait-time / delay-sensitive traffic.

[0047] The WD may provide filtered measurement reports to radio network nodes. Filtered measurement reports can be affected when the WD skips measurement gaps and / or performs partial measurements. Filtered measurement reports can be considered herein as measurement reports to which filtering (such as L1 filtering and / or L3 filtering) has been applied. Filtered measurement reports may include indications of measurements based on conditions where one or more measurement gaps have not yet been used (e.g., have been skipped and / or only partially used).

[0048] Figure 7 This is a signaling diagram illustrating an example message exchange 700 between radio network node 400 and WD 300 for processing UL data transmission during a configured measurement gap, according to this disclosure. The proposed method can also be applied to DL data transmission. WD 300 may be in an RRC connected state. In the RRC connected state, an RRC connection is established, and the network has configured WD 300 with all the necessary parameters for communication between WD 300 and radio network node 400.

[0049] The WD 300 and radio network node 400 exchange information 701 indicating the following configuration: - Measurement gaps to be used by the WD 300 to perform signal quality measurements from one or more cells (such as the serving cell and / or one or more neighboring cells), and / or - Indicates the type of data transfer to be performed, such as whether the data transfer is time-sensitive, like XR data transfer. For example, the configured authorization settings are typically used for XR data transfer, and... - Information related to the ability to handle modifications to the measurement gap configuration (such as in Figure 9A (As described in S101).

[0050] The configuration of the measurement gap corresponds to in Figure 9A and Figure 9B The configuration transmitted by radio network node 400 in S103.

[0051] Information indicating the configuration of the measurement gap can be transmitted from the radio network node 400 to the WD 300. Information indicating the type of data transmission being performed can be transmitted from the WD 300 to the radio network node 400 for uplink type transmission, and can be transmitted from the radio network node 400 to the WD 300 for downlink type transmission.

[0052] When the WD 300 detects a transmission time conflict between an upcoming data transmission in the UL and a configured measurement gap, the WD 300 may transmit information 703 indicating that a conflict has been detected to the radio network node 400. A conflict may occur when the upcoming data transmission is scheduled to occur within the same time resource as the configured measurement gap. In one or more example methods, the information indicating that a conflict has been detected includes a request to skip the conflicting configured measurement gap. In one or more example methods, the WD 300 may detect a conflict during the on-duration of the WD 300's discontinuous reception (DRX) cycle. The indication of a conflict may be transmitted via L1 signaling, such as via the Physical Uplink Control Channel (PUCCH) and / or MAC CE. New parameters for this indication may be present in the Uplink Control Information (UCI) and / or MAC CE parameter / information elements carried by the PUCCH. Information 703 corresponds to... Figure 9A In the S105A, it is received by the radio network node and in Figure 10 The message received in S206.

[0053] In response to receiving information indicating that a conflict has been detected, radio network node 400 may send information 704 indicating a temporary modification to the configured measurement gap. In one or more example methods, the information indicating the temporary modification indicates skipping one or more measurement gaps, such as one or more configured measurement gaps. In one or more examples, information 704 may include an acknowledgment (ACK) or an indication to skip the conflicting configured measurement gap instead of continuing data transmission in the time resources allocated in the configured measurement gap. The scheduler in the network node may also detect potential upcoming conflicts between data transmission / reception and measurement. Once detected, network node 400 may send information 704 without receiving information 703. In one or more example methods, the information indicating the temporary modification may include a negative acknowledgment (NACK) for skipping the conflicting configured measurement gap. NACK may indicate that WD is refused to skip the conflicting configured measurement gap. In another example, the radio network node only provides an indication (such as ACK). In other words, if WD does not receive an ACK, WD may interpret this as WD not being allowed to skip the configured measurement gap. In this case, WD 300 continues to perform measurements according to the configured measurement gap as the default operation. In one or more example methods, the information indicating temporary modification indicates a reduction in the length of one or more measurement gaps (such as one or more configured measurement gaps). In one or more example methods, the information indicating temporary modification indicates a shift of one or more measurement gaps (such as configured measurement gaps) in the time domain. In one or more example methods, a radio network node may determine whether radio conditions (such as signal quality in the cell) are sufficient before transmitting information 704. Radio conditions may be sufficient when signal quality in the cell meets signal quality criteria. Signal quality criteria may, for example, be signal quality thresholds. Signal quality thresholds may refer to instantaneous thresholds used for measurement or average or other statistical measurement (such as standard deviation) thresholds. These thresholds may be defined and described in specifications (such as 3GPP specifications) or may depend on the implementation of the radio network node. Once signal quality criteria are met, such as when signal quality is equal to or higher than the signal quality threshold, the radio network node may determine that the signal quality of the serving cell is sufficient and may continue transmitting information 704. If it is determined that radio conditions are not met (such as signal quality not meeting the signal quality threshold), radio network node 400 may prevent transmission of information 704. Information 704 corresponds to Figure 9B The S110 and in Figure 10 It is received in S210.

[0054] In one or more example methods, the WD 300 and the radio network node may have an implicit agreement: skipping measurement gaps can be performed by transmitting information 703 and receiving information 704. The WD 300 can therefore perform data transmission and / or reception in the conflicting measurement gap upon detection of a collision.

[0055] The WD 300 transmits data according to message 704, which indicates a temporary modification. When the message indicates that WD can skip one or more configured measurement gaps, the WD 300 refrains from performing the measurement and transmits data during the configured measurement gap.

[0056] Figure 8 This is a signaling diagram illustrating an example message exchange 800 between radio network node 400 and WD 300 for DL ​​data transmission during a measurement gap, according to this disclosure. WD 300 may be in RRC connected state.

[0057] The WD 300 and radio network node 400 exchange information 801, which indicates the configuration of the measurement gap to be used by the WD 300 to perform signal quality measurements from one or more cells (such as the serving cell and / or one or more neighboring cells), and / or indicates the type of data transmission being performed (such as whether the data transmission is a latency-sensitive transmission, such as XR data transmission). Information indicating the configuration of the measurement gap can be transmitted from the radio network node 400 to the WD 300. Information indicating the type of data transmission being performed can be transmitted from the WD 300 to the radio network node 400.

[0058] When radio network node 400 detects a conflict between an upcoming data transmission in the DL and a configured measurement gap, such as when the upcoming data transmission is scheduled within the same time resource as the configured measurement gap, radio network node 400 triggers WD 300 to provide a measurement report based on a signal quality measurement performed in a previous measurement gap by sending message 803 to WD 300, which includes information to trigger the measurement. Message 803 can be transmitted using L1 signaling (e.g., DCI and / or MAC CE signaling). In one or more example methods, new parameters, such as a trigger indication, can be added to the downlink control information (DCI) carried by PDCCH and / or the MAC CE parameter / information elements used for triggering. Message 703 corresponds to... Figure 9A In the S105A, it is received by the radio network node and in Figure 10 The message received in S206.

[0059] In response to this trigger, the WD 300 may send a measurement report 804 to a radio network node, wherein the measurement is based on measurements performed in one or more previous measurement gaps, such as one or more measurements performed prior to receiving the trigger. The measurement report may be based on L1-filtered measurements and / or L3-filtered measurements. The measurement report may include an indication that the reported measurement is affected by a temporary modification, such as a temporary modification based on the configured measurement gap.

[0060] Upon receiving measurement report 804, radio network node 400 can determine, based on the measurement report, whether signal quality 805 meets signal quality criteria. Signal quality criteria can be, for example, signal quality thresholds. Signal quality thresholds can refer to instantaneous thresholds for measurements or average or other statistical measurement (such as standard deviation) thresholds. These thresholds can be defined and described in specifications (such as 3GPP specifications) or up to the network node implementation. Once signal quality criteria are met, such as when signal quality is equal to or greater than the signal quality threshold, the radio network node can determine that the signal quality of the serving cell is sufficient to allow modification of the configured measurement gaps, such as skipping upcoming measurement gaps, reducing the length of upcoming measurement gaps, and / or shifting the configured measurement gaps in time.

[0061] When radio network node 400 determines that the signal meets the signal quality standard, the radio network node sends information 806 indicating an upcoming modification to the measurement gap, such as skipping, reducing the length of the measurement gap, and / or shifting the time of the measurement gap. This message 806 corresponds to... Figure 7 Message 704 in the signaling diagram Figure 10 Action S210 and Figure 9B Action S110.

[0062] Radio network node 400 can skip the configured measurement gap in the time resources of the configured measurement gap to continue DL data transmission 807.

[0063] Figure 9A and Figure 9B A flowchart is shown of an example method 100 for processing transmissions between a radio network node and a WD, performed by a radio network node according to this disclosure. The radio network node is the radio network node disclosed herein, such as... Figure 1 and Figure 2 , Figure 4 , Figures 7 to 8 as well as Figure 11 400 radio network nodes.

[0064] The WD's ability to handle modified measurement gaps can be controlled by, for example, WD capabilities or auxiliary information. Therefore, in one or more example methods, method 100 includes WD transmitting S101 information related to the ability to handle modifications to the configured measurement gap. In one or more example methods, transmission S101 includes transmitting S101A information related to the ability to handle modifications to the configured measurement gap to the WD. In one or more example methods, transmission S101 includes receiving S101B information from the WD related to the ability to handle modifications to the configured measurement gap. The information related to the ability to handle modifications to the configured measurement gap may include one or more information related to the ability to prevent measurement during the measurement gap and the ability to perform measurement within a portion of the measurement gap.

[0065] WDs requiring measurement gaps (such as those used to determine cell conditions) are typically configured with periodic gaps (referred to herein as measurement gaps). During these gaps, the WD performs measurements and does not need to receive and / or transmit data. In other words, method 100 includes transmitting S103 to the WD a configuration of measurement gaps for the WD to perform signal quality measurements (such as quality measurements of signals received from one or more beams from the serving cell and / or one or more neighboring cells). In one or more example methods, the signal quality measurement may be an RRM measurement, such as an RSRP measurement. In one or more example methods, the measurement gap, such as the configured measurement gap, is a time gap. In the default configuration, the configured measurement gap (such as the configuration) identifies a time period specifically allocated for performing measurements. In other words, in the default configuration, the configured measurement gap is a time period during which data transmission is not permitted, and the WD is configured to perform measurements (such as signal quality measurements) against one or more beams from the serving cell and / or neighboring cells. Measurement gaps can therefore be viewed as interruptions in the data stream between the radio network node and the WD, such as interruptions in the data stream to allow the WD to perform measurements.

[0066] The WD can be configured by the network with periodically repeating resources, such as CGs, for UL data transmission. CGs can be pre-allocated to the WD. By scheduling UL transmissions using CGs, the need to request and allocate resources for each packet transmission can be eliminated. Thus, in one or more example methods, method 100 includes scheduling S104 for data transmission between the WD 300 and the radio network node 400. In other words, the radio network node can authorize the scheduling configuration for data transmission between the WD 300 and the radio network node 400.

[0067] Method 100 includes obtaining an indication, in S105, of a potential conflict (such as a potential conflict) between an upcoming data transmission and a configured measurement gap. A potential conflict can be considered herein as a temporal conflict between data transmission and a configured measurement gap. In other words, a conflict can occur when data transmission (such as authorization for configuration of data transmission) and a configured measurement gap are scheduled in the same time frame (such as in the same OFDM subframe). In one or more example methods, the upcoming data transmission is a time-critical data transmission, a periodically recurring data transmission allocated to pre-allocated resources (such as CG), and / or an intermittent data transmission. For example, XR applications typically utilize CG transmissions for operation. In this context, an intermittent data transmission can be considered a sudden (e.g., unschedulable) data transmission. An intermittent data transmission may not be schedulable because it can be triggered by a triggering event. The triggering event can be higher-layer signaling, such as DL data transmission from a radio network node. An intermittent data transmission can be UL data transmission from a WD triggered by a triggering event. The triggering event can be, for example, the reception of DL data transmission. Time-critical data transfers (such as timers) can be time-sensitive transfers, such as XR data transfers, or data transfers that require zero-delay transmission.

[0068] In one or more example methods, such as when an upcoming data transmission is in the UL, obtaining S105 includes receiving an S105A indication from the WD 300, which indicates a conflict between the upcoming data transmission and the configured measurement gap. In one or more example methods, the information indicating that a conflict has been detected may include a request to skip the upcoming configured measurement gap. The indication of the conflict may be received via 3GPP L1 signaling, such as via the Physical Uplink Control Channel (PUCCH) and / or MAC CE. Receiving S105A corresponds to Figure 10 Transmission S206 and Figure 7 Signaling 703 in the middle.

[0069] In one or more example methods, such as when an upcoming data transmission is in the DL, obtaining S105 includes detecting a conflict between the upcoming data transmission and the configured measurement gap (S105B). Receiving S105A corresponds to... Figure 8 Signaling 802 in the middle.

[0070] Channel conditions affect the quality of data transmission and / or reception. If channel conditions are poor, data may be lost. To ensure adequate channel conditions, the WD is configured to perform measurements on the cell, for example, to determine whether the WD will switch from the serving cell to a neighboring cell. If channel conditions are poor, skipping measurement gaps can prevent the WD from providing the measurement information needed to determine whether a handover is necessary. Therefore, in one or more example methods, method 100 includes triggering S106 for the WD 300 to provide a measurement report based on signal quality measurements performed in a previous measurement gap. When the radio network node 400 detects a conflict between an upcoming data transmission and a configured measurement gap, the radio network node 400 may send a message to the WD 300 including information that triggers the WD 300 to provide a measurement report based on signal quality measurements performed in one or more previous measurement gaps, such as measurement gaps configured before the measurement report is triggered. L1 signaling (e.g., DCI and / or MAC CE signaling) can be used to transmit the trigger for providing the measurement report (e.g., a message including information triggering the WD). Unlike conventional triggering of measurements that only occur when a handover from a WD to a new cell is required, signal quality measurements according to this disclosure are triggered based on a conflict detected between upcoming data traffic and a configured measurement interval. Trigger S106 corresponds to... Figure 10 The receiving S207 and Figure 8 Signaling 803.

[0071] In one or more example methods, method 100 includes receiving a measurement report from WD S107 based on measurements performed in a previous measurement interval. The measurement report can be received using L1 signaling.

[0072] In one or more example methods, method 100 includes determining whether the signal quality of S108 meets a signal quality standard based on a measurement report from WD. The signal quality standard may, for example, be a signal quality threshold. Once the signal quality standard is met, such as when the signal quality is equal to or greater than the signal quality threshold, the radio network node can determine that the signal quality of the serving cell is sufficient to allow modification of the configured measurement gap. Modification of the configured measurement gap may herein include skipping an upcoming measurement gap, reducing the length of an upcoming measurement gap, and / or shifting the configured measurement gap.

[0073] If signal quality standards are not met, such as when the signal quality is below a signal quality threshold, a radio network node can determine that the signal quality of the serving cell is insufficient to allow modification of the measurement gap of one or more configurations in the time domain.

[0074] In one or more example methods, method 100 includes, for example, temporarily modifying the measurement gap configured in S109 when it is determined that the signal quality meets a signal quality criterion. In one or more example methods, temporarily modifying the configured measurement gap includes skipping upcoming measurement gaps, such as the upcoming measurement gap of the configured measurement gap. In one or more example methods, temporarily modifying the configured measurement gap includes, for example, reducing the length of the upcoming measurement gap by defining a virtual measurement gap having a shorter length than the configured measurement gap. In one or more example methods, temporarily modifying the configured measurement gap includes shifting (e.g., moving) the configured measurement gap. Shifting the configured measurement gap can be considered herein as shifting the configured measurement gap in the time domain, changing or not changing the MGL of the configured measurement gap. It can change the start time of the measurement gap and / or reduce the MGL. By temporarily modifying the configured measurement gap, the resources allocated to the measurement can be used by the WD to send and / or receive latency- and / or delay-sensitive data.

[0075] To enable WD to apply the modified measurement gap, method 100 includes transmitting to WD information S110 indicating a temporary modification to the configured measurement gap. In one or more example methods, the information indicating the temporary modification indicates skipping one or more measurement gaps, such as one or more of the configured measurement gaps. This can be indicated by providing an indication of when to skip and / or release the configured measurement gaps or by providing an indication to perform data transmission and / or reception during the configured measurement gaps.

[0076] In one or more example methods, the information indicating temporary modification indicates a reduction in the length of one or more configured measurement gaps, for example, by providing a virtual measurement gap (such as a virtual measurement window) with a shorter length than the configured measurement gap. The virtual measurement gap can be included within the configured measurement gap timing, such as within the length of the configured measurement gap. In other words, the virtual measurement gap can be a sub-section of the configured measurement gap. The length of the virtual measurement gap can be shorter than the configured measurement gap length, and thus allows the WD to transmit and / or receive data in the portion of the configured measurement gap not allocated to the virtual measurement gap. When configuring a virtual measurement gap, the information indicating temporary modification can include the actual location of the virtual measurement gap. The actual location can be provided by indicating one or more of a time offset value and length of the virtual measurement gap. The time offset value can be an offset relative to the starting point of the configured measurement gap. The granularity of the time offset and / or the length of the virtual measurement gap can be at the OFDM symbol level. In one or more example methods, one or more of these parameters can also be provided via higher-level signaling (such as RRC signaling). In this case, the radio network node can instruct the WD to perform partial measurements within the configured measurement gap timing. This can, for example, be applied to situations where data transmission and / or reception partially conflict with the configured measurement gap, such as in... Figure 6 The example shown is shown in the image.

[0077] In one or more example methods, information indicating temporary modifications indicates a shift of one or more measurement gaps (such as configured measurement gaps) in the time domain.

[0078] In one or more example methods, information indicating temporary modifications can be provided prior to the measurement interval. This could be, for example, when measurements and data transmissions are in different bandwidth portions, such as for inter-frequency measurements.

[0079] In one or more example methods, information indicating temporary modifications can be provided during measurement gaps. This applies when measurement and data transmission occur within the same bandwidth, such as for intra-frequency measurements.

[0080] In one or more example methods, information indicating temporary modifications may be provided as headers and / or flags in a message. In one or more example methods, information indicating temporary modifications to the configured measurement gap is transmitted using one or more of DCI, MAC CE, and RRC signaling. RRC signaling may be used to provide indications of temporarily modified configurations, such as rule and / or general configurations. RRC signaling (such as an RRC message) may be provided to the WD indicating that the WD is permitted to perform data transmission and / or reception by modifying the configured measurement gap whenever there is a conflict between data transmission and / or reception and measurement (until further notification). DCI or MAC CE may be used to transmit indications of actual modifications used at a given time (such as for a given measurement gap). For example, the length of a virtual measurement gap may be provided via RRC signaling, while the time offset may be part of an indication sent via lower-level signaling (such as via DCI or MAC CE).

[0081] In one or more example methods, such as when the WD has indicated a conflict between data transmission and measurement gaps, the information indicating a temporary modification may include an ACK, which is used to skip the conflicting configured measurement gap instead of continuing data transmission in the time resources allocated in the configured measurement gap. In one or more example methods, the information indicating a temporary modification may include a NACK for skipping the conflicting configured measurement gap. A NACK may indicate that the WD is refused to skip the conflicting configured measurement gap. Transmission S110 corresponds to... Figure 10 Receiver S210, Figure 7 Message 704 and Figure 8 The message is 804.

[0082] In one or more example methods, a radio network node may signal to the WD (such as by transmitting a message including an indication) to enable and / or disable data transmission and / or reception during a configured measurement gap. This signaling may be WD-specific and may be included in information indicating a temporary modification to the configured measurement gap, or it may be a separate signaling, such as a message.

[0083] In one or more example methods, the information indicating the temporary modification includes a measurement configuration to be used by the WD to perform measurements based on the temporary modification. In one or more examples, the measurement configuration may include dedicated parameters for the WD to measure signal quality. Dedicated parameters may be, for example, dedicated filter coefficients, such as filter coefficients used to update L3 measurement filters (such as L3 beam measurement filters) to include information about beams that have not yet been measured (such as beams that have been completely or partially skipped).

[0084] In conventional signal quality measurements, the WD can perform multiple measurements in subsequent measurement gaps, filter the measurements, and provide a measurement report to radio network nodes that includes the filtered measurements. If one or more of these currently disclosed measurements are affected by temporary modifications, the WD can use the received measurement configuration (e.g., new filter coefficients) to include information about beams that have not yet been measured (e.g., beams that have been completely or partially skipped).

[0085] In one or more example methods, method 100 includes participating in S111 data communication according to a temporary modification. Participating in data communication according to the temporary modification can be regarded herein as transmitting and / or receiving data during at least a portion of a configured measurement gap. In other words, a radio network node can receive data from the WD and / or transmit data to the WD during the configured measurement gap.

[0086] Figure 10 A flowchart is shown of an example method 200 for processing transmissions between a wireless device and a radio network node, performed by a wireless device according to the present disclosure. The wireless device is the wireless device disclosed herein, such as… Figure 1 , Figure 7 , Figure 8 and Figure 12 The wireless device 300.

[0087] In one or more example methods, method 200 includes information related to the ability of a radio network node to transmit S201 and process modifications to the configured measurement gap. In one or more example methods, transmission S201 includes receiving information (S201A) from radio network node 400 related to the ability to process modifications to the configured measurement gap. In one or more example methods, transmission S201 includes sending S201B to radio network node 400 information related to the ability to process modifications to the configured measurement gap. The information related to the ability to process modifications to the configured measurement gap may include information related to one or more of the following capabilities: the ability to avoid performing measurements during the configured measurement gap, such as the ability to transmit data during the configured measurement gap, and the ability to perform measurements within a portion of the configured measurement gap. Here, avoiding performing measurements during the configured measurement gap can be considered as the ability to skip the configured measurement gap.

[0088] Method 200 includes receiving a configured measurement gap from a radio network node (S203 WD) to perform signal quality measurements, such as quality measurements of signals received from one or more beams of the serving cell and / or one or more neighboring cells. In one or more example methods, the signal quality measurement may be an RRM measurement, such as an RSRP measurement. In one or more example methods, the measurement gap, such as the configured measurement gap, is a time gap. In one or more example methods, the configured measurement gap identifies a time period specifically allocated for performing the measurement. In other words, the configured measurement gap is a time period during which data transmission is not permitted, and the WD is configured to perform measurements, such as signal quality measurements, on one or more beams from the serving cell and / or neighboring cells. The measurement gap can therefore be viewed as an interruption in the data stream between the radio network node and the WD, such as an interruption in the data stream to allow the WD to perform the measurement.

[0089] In one or more example methods, for example when an upcoming data transmission is in the UL, method 200 includes detecting a conflict, such as a potential conflict, between the upcoming data transmission and the configured measurement gap in S205. A potential conflict can be considered herein as a potential temporal conflict between the data transmission and the configured measurement gap. In other words, a conflict may occur when the data transmission (such as authorization for the configuration of the data transmission) and the configured measurement gap are scheduled in the same time frame (such as in the same OFDM subframe). In one or more example methods, the upcoming data transmission is a time-critical data transmission and / or an incidental data transmission. Here, an incidental data transmission can be considered a sudden (e.g., unschedulable) data transmission. An incidental data transmission may not be schedulable because it can be triggered by a triggering event. The triggering event can be higher-level signaling, such as DL data transmission from a radio network node. An incidental data transmission can be UL data transmission from the WD triggered by a triggering event, such as DL data transmission.

[0090] In one or more example methods, such as when an upcoming data transmission is in the UL, method 200 includes transmitting S206 to a radio network node an indication of a conflict between the upcoming data transmission and a configured measurement gap. Transmitting S206 corresponds to... Figure 9A The receiver S105A and Figure 7 Signaling 703 in the middle.

[0091] In one or more example methods, such as when an upcoming data transmission is in the DL and a collision is detected by the radio network node, method 200 includes receiving from the radio network node a trigger S207 to provide a measurement report based on signal quality measurements performed in a previous measurement gap. The WD may receive a message from the radio network node that may include information triggering the WD to provide a measurement report based on measurements (such as signal quality measurements) performed in one or more previous measurement gaps (such as measurement gaps configured prior to receiving the trigger to provide the measurement report). This trigger (such as a message including information triggering the WD to provide the measurement report) may be received using L1 and / or MAC CE signaling.

[0092] In one or more example methods, method 200 includes providing an S208 measurement report to a radio network node, such as a measurement report based on measurements performed in one or more previous measurement gaps. The measurement report may include an indication that the reported measurement is affected by a temporary modification, such as a temporary modification based on a configured measurement gap. In response to receiving a trigger from the radio network node, the measurement report may be provided to (e.g., transmitted) the radio network node.

[0093] Method 200 includes receiving from a radio network node S210 information indicating a temporary modification to a configured measurement gap. In one or more example methods, the information indicating the temporary modification indicates one or more of the following: skipping one or more measurement gaps, reducing the length of one or more measurement gaps, and / or shifting one or more measurement gaps in the time domain. In one or more example methods, the information indicating the temporary modification includes a measurement configuration to be used by the WD to perform measurements according to the temporary modification. In one or more example methods, the information indicating the temporary modification to the configured measurement gap is transmitted using one or more of DCI, MAC CE, and RRC signaling. This action S210 corresponds to Figure 7 Message 704 in the signaling diagram Figure 8 Message 804 and Figure 9B Action S110.

[0094] In one or more example methods, method 200 includes participating in data communication S211 according to a temporary modification. Participating in data communication according to the temporary modification can be considered herein as transmitting and / or receiving data during at least a portion of a configured measurement gap. In other words, the WD can transmit data to and / or receive data from a radio network node during a configured measurement gap.

[0095] Figure 11A block diagram of an exemplary radio network node 400 according to the present disclosure is shown. The radio network node 400 includes memory circuitry 401, processor circuitry 402, and a wireless interface 403. The radio network node 400 can be configured to perform... Figure 9A and Figure 9B Any method disclosed herein. In other words, network node 400 can be configured to handle transmissions between radio network node 400 and WD.

[0096] Network node 400 is configured to communicate with WD (such as the WD 300 disclosed herein) using a wireless communication system.

[0097] The wireless interface 403 is configured to communicate wirelessly via a wireless communication system, such as a 3GPP system, such as a 3GPP system that supports one or more of the following: New Radio, NR, NR Advanced, Beyond NR, LTE, Narrowband IoT, NB-IoT and LTE-Enhanced Machine Type Communications, LTE-M and 3GPP systems operating in licensed or unlicensed frequency bands.

[0098] The radio network node 400 is configured, for example, to send a measurement gap to the WD via the wireless interface 403 for the WD to perform signal quality measurements.

[0099] Radio network node 400 is configured, for example, to receive indications of conflicts between upcoming data transmission and configuration measurement gaps via wireless interface 403 and / or processor circuitry 402.

[0100] Radio network node 400 is configured to send, for example, information to WD via wireless interface 403 indicating a temporary modification to the configured measurement gap.

[0101] Processor circuit 402 is optionally configured to perform in Figure 9A and Figure 9B Any operation disclosed in the code (such as any one or more of S101, S101A, S101B, S103, S105, S105A, S105B, S106, S107, S108, S109, S110, and S111). The operation of the radio network node 400 may be embodied in the form of an executable logic routine (e.g., lines of code, software program, etc.) stored on a non-transitory computer-readable medium (e.g., memory circuitry 401) and executed by processor circuitry 402.

[0102] Furthermore, the operation of network node 400 can be considered as a method configured to be performed by network node 400. Moreover, although the described functions and operations can be implemented in software, such functions can also be performed via dedicated hardware or firmware, or some combination of hardware, firmware and / or software.

[0103] The memory circuit 401 may be one or more of a buffer, flash memory, hard disk drive, removable media, volatile memory, non-volatile memory, random access memory (RAM), or other suitable devices. In a typical arrangement, the memory circuit 401 may include non-volatile memory for long-term data storage and volatile memory used as system memory for the processor circuit 402. The memory circuit 401 may exchange data with the processor circuit 402 via a data bus. Control lines and an address bus may also exist between the memory circuit 401 and the processor circuit 402. Figure 11 (Not shown in the image). The memory circuit 401 is considered a non-transitory computer-readable medium.

[0104] The memory circuit 401 can be configured to store information in a portion of the memory, such as measurement gap configuration, information indicating temporary modifications to the configured measurement gap, measurement reports, and / or signal quality measurements.

[0105] Figure 12 A block diagram of an exemplary wireless device 300 according to the present disclosure is shown. The wireless device 300 includes memory circuitry 301, processor circuitry 302, and a wireless interface 303. The wireless device 300 can be configured to perform... Figure 10 Any of the methods disclosed herein. In other words, the wireless device 300 can be configured to handle transmissions between the WD and the radio network node.

[0106] The wireless device 300 is configured to communicate with network nodes (e.g., radio network nodes disclosed herein) using a wireless communication system.

[0107] The wireless device 300 is configured to receive, for example via wireless interface 303, a configured measurement gap from a radio network node for WD to perform signal quality measurements.

[0108] The wireless device 300 is configured (e.g., via wireless interface 303) to receive information from a radio network node indicating temporary modifications to the configured measurement gap.
