[0001] CANCELLING MEASUREMENT REPORTING

[0002] CROSS-REFERENCE TO RELATED APPLICATION

[0003]

[0001] The present application claims priority to, and the benefit of, Finland Application No. 20245392, filed April 3, 2024, the contents of which are hereby incorporated by reference in their entirety.

[0004] FIELDS

[0005]

[0002] Example embodiments of the present disclosure generally relate to the field of communication techniques and in particular, to devices and methods for cancelling measurement reporting.

[0006] BACKGROUND

[0007]

[0003] In order to meet the increasing wireless data traffic demand, a plurality of schemes have been proposed and implemented, where the multiple input multiple output (MIMO) technology is considered as one powerful scheme to achieve high data throughputs in the communication system.

[0004] Generally speaking, during the communication between the terminal device and the network device, the terminal device needs to report channel status information (CSI) feedback to the network device, such that the network device may understand the network condition and make a more proper subsequent radio management. In some scenarios, the communication condition and the configurations may be changed. If so, the reported CSI feedback may be not relevant (i.e. , out of date) for the future radio management. As a result, such reporting may be unnecessary and should be avoided accordingly.

[0039]

[0036] As used herein, the term “communication network” refers to a network following any suitable communication standards, such as New Radio (NR), Long Term Evolution (LTE), LTE-Advanced (LTE-A), Wideband Code Division Multiple Access (WCDMA), High-Speed Packet Access (HSPA), Narrow Band Internet of Things (NB-loT) and so on. Furthermore, the communications between a terminal device and a network device in the communication network may be performed according to any suitable generation communication protocols, including, but not limited to, the first generation (1 G), the second generation (2G), 2.5G, 2.75G, the third generation (3G), the fourth generation (4G), 4.5G, the fifth generation (5G), 5.5G, the sixth generation (6G) communication protocols, and / or any other protocols either currently known or to be developed in the future. Embodiments of the present disclosure may be applied in various communication systems. Given the rapid development in communications, there will of course also be future type communication technologies and systems with which the present disclosure may be embodied. It should not be seen as limiting the scope of the present disclosure to only the aforementioned system.

[0040]

[0037] As used herein, the term “network device” refers to a node in a communication network via which a terminal device accesses the network and receives services therefrom. The network device may refer to a base station (BS) or an access point (AP), for example, a node B (NodeB or NB), an evolved NodeB (eNodeB or eNB), an NR NB (also referred to as a gNB), a Remote Radio Unit (RRU), a radio header (RH), a remote radio head (RRH), a relay, an Integrated Access and Backhaul (IAB) node, a low power node such as a femto, a pico, a non-terrestrial network (NTN) or non-ground network device such as a satellite network device, a low earth orbit (LEO) satellite and a geosynchronous earth orbit (GEO) satellite, an aircraft network device, and so forth, depending on the applied terminology and technology. In some example embodiments, radio access network (RAN) split architecture comprises a Centralized Unit (CU) and a Distributed Unit (DU) at an IAB donor node. An IAB node comprises a Mobile Terminal (IAB-MT) part that behaves like a UE toward the parent node, and a DU part of an IAB node behaves like a base station toward the next-hop IAB node.

[0041]

[0038] The term “terminal device” refers to any end device that may be capable of wireless communication. By way of example rather than limitation, a terminal device may also be referred to as a communication device, user equipment (UE), a Subscriber Station (SS), a Portable Subscriber Station, a Mobile Station (MS), or an Access Terminal (AT). The terminal device may include, but not limited to, a mobile phone, a cellular phone, a smart phone, voice over IP (VoIP) phones, wireless local loop phones, a tablet, a wearable terminal device, a personal digital assistant (PDA), portable computers, desktop computer, image capture terminal devices such as digital cameras, gaming terminal devices, music storage and playback appliances, vehiclemounted wireless terminal devices, wireless endpoints, mobile stations, laptop-embedded equipment (LEE), laptop-mounted equipment (LME), USB dongles, smart devices, wireless customer-premises equipment (CPE), an I nternet of Things (loT) device, a watch or other wearable, a head-mounted display (HMD), a vehicle, a drone, a medical device and applications (e.g., remote surgery), an industrial device and applications (e.g., a robot and / or other wireless devices operating in an industrial and / or an automated processing chain contexts), a consumer electronics device, a device operating on commercial and / or industrial wireless networks, and the like. The terminal device may also correspond to a Mobile Termination (MT) part of an IAB node (e.g., a relay node). In the following description, the terms “terminal device”, “communication device”, “terminal”, “user equipment” and “UE” may be used interchangeably.

[0042]

[0039] As used herein, the term “resource,” “transmission resource,” “resource block,” “physical resource block” (PRB), “uplink resource,” or “downlink resource” may refer to any resource for performing a communication, for example, a communication between a terminal device and a network device, such as a resource in time domain, a resource in frequency domain, a resource in space domain, a resource in code domain, or any other combination of the time, frequency, space and / or code domain resource enabling a communication, and the like. In the following, unless explicitly stated, a resource in both frequency domain and time domain will be used as an example of a transmission resource for describing some example embodiments of the present disclosure. It is noted that example embodiments of the present disclosure are equally applicable to other resources in other domains.

[0043]

[0040] As discussed above, MIMO has been utilized as powerful scheme to achieve high data throughputs in the communication system. Further, during the communication between the terminal device and the network device, the terminal device needs to report CSI feedback to the network device, such that the network device may understand the network condition and make a more proper subsequent radio management.

[0044]

[0041] In release 19 MIMO Phase5 enhancements, one of the objectives is the UE event driven reporting (also called as event-base reporting / event-driven reporting):

[0045] • Specify enhancement to facilitate UE-initiated / event-driven beam management for reducing overhead and / or latency, assuming the unified transmission configuration indicator (TCI) while leveraging (as much as possible) legacy CSI measurement and reporting configuration frameworks, targeting frequency range

[0046] 2 (FR2) and single transmission reception point (TRP) with intra-cell and inter-cell beam management, o UL signaling content(s) (and procedure(s) as required) for UE-initiated / event-driven beam reporting facilitating fast beam switching; o UL signaling medium / container considering the UE-initiated / event-driven nature of the UL transmission, designed primarily for the purpose of beam reporting.

[0047]

[0042] With respect to the MIMO / beam management (BM) enhancements, it has been agreed that as for UE-initiated / event-driven beam report, at least of following aspects should be included:

[0048] • Trigger-event detection for beam reporting by UE;

[0049] UE monitors RS to assess if a beam-reporting trigger condition has been met;

[0050] Trigger condition for declaring beam-reporting event needs further discussions;

[0051] • Beam-report transmission by UE;

[0052] Signaling contents in the beam report;

[0053] Down-selection one or more options (strive for one) between the following options as signaling medium / container for beam report transmission: medium access control (MAC) control element (CE), uplink control information (UCI) and other suitable signalling / message;

[0054] • UE requesting UL resource(s) for the beam report;

[0055] • UE notifying transmission of beam report;

[0056] • gNB preconfigured resources;

[0057] • Other procedure(s) as required.

[0058]

[0043] On UE-initiated / event-driven beam reporting, regarding trigger-event detection for beam reporting, RAN 1 further study at least the following aspects: quality metrics, event-definition and threshold.

[0059]

[0044] It also has been agreed to further study trigger events, including the following example as a starting point:

[0060] • Event-1 : Quality of the current beam is worse than a certain threshold. • Event-2: Quality of at least one new beam, such as L1 -RSRP, becomes a threshold value better than the current beam.

[0061] • Event-3: Quality of a new beam is better than a certain threshold.

[0062] • Event-4: Quality of the current beam is worse than a threshold 1, and quality of at least one new beam is better than a threshold 2.

[0063] • Others are not precluded.

[0064]

[0045] Furthermore, one of the objectives of 3GPP NR release 19 mobility enhancements, is to specify necessary components to support event triggered layer 1 (L1) measurement reporting (such as CSI reporting but not limited to it) for L1 / L2 triggered mobility (LTM), which may be L1 / L2 centric mobility, lower layer triggered mobility, L2 mobility.

[0065]

[0046] In some scenarios, the communication conditions and the configurations may be changed. If so, the reported CSI feedback may be not relevant (i.e., out of date) for the future radio management. As a result, such reporting may be unnecessary and should be avoided accordingly.

[0047] According to some embodiment of the present discourse, a solution for cancelling measurement reporting is proposed. In this solution, the first apparatus (such as, a UE) receives, from a second apparatus (such as, gNB), a configuration for performing measurement reporting triggered by an event; determines that at least one condition for the measurement reporting triggered by the event is met; and based on the determining that the at least one condition is met, cancels the measurement reporting to the second apparatus.

[0066]

[0048] In this way, the unnecessary measurement reporting may be cancelled properly and the uplink resource utilization is enhanced thereby.

[0067]

[0049] It is to be understood although some example embodiments are discussed by using CSI reporting, the measurement reporting discussed herein may refer to any suitable measured / predicted results reporting.

[0068]

[0050] In the context of the present disclosure, wording “cancelling the measurement reporting” may be replaced by “disabling the measurement reporting”, “stopping the measurement reporting”, “terminating the measurement reporting” and other similar wordings.

[0069]

[0051] In the context of the present disclosure, “measurement reporting” may refer to “pending measurement reporting” and / or “triggered measurement reporting”. In other words, “measurement reporting” discussed herein refers to a measurement reporting that has not been transmitted to a further apparatus successfully. Example environment

[0070]

[0052] FIG. 1 illustrates an example communication environment 100 in which example embodiments of the present disclosure can be implemented. The communication environment 100 includes a first apparatus 110 and a second apparatus 120. A serving area provided by the second apparatus 120 is called a cell. The second apparatus 120 can provide one or more cells, for example, a cell 102 as illustrated in FIG. 1 .

[0071]

[0053] In some example embodiments, the first apparatus 110 may be comprised in a terminal device and the second apparatus 120 may be comprised in a network device serving the terminal apparatus.

[0072]

[0054] In the following, for the purpose of illustration, some example embodiments are described with the first apparatus 110 operating as a terminal apparatus and the second apparatus 120 operating as a network apparatus. However, in some example embodiments, operations described in connection with a terminal apparatus may be implemented at a network apparatus or other apparatus, and operations described in connection with a network apparatus may be implemented at a terminal apparatus or other apparatus.

[0073]

[0055] As one example scenario, the first apparatus 110 may include a terminal device and the second apparatus 120 may include a network device serving the terminal device. In this specific example embodiment, a link from the first apparatus 110 to the second apparatus 120 is referred to as uplink, while a link from the second apparatus 120 to the first apparatus 110 is referred to as a downlink.

[0074]

[0056] In downlink, the second apparatus 120 is a transmitting (TX) device (or a transmitter) and the first apparatus 110 is a receiving (RX) device (or a receiver), and the second apparatus 120 may transmit downlink transmission to the first apparatus 110 via one or more beams. As illustrated in FIG. 1 , the second apparatus 120 transmits downlink transmission to the first apparatus 110 via the beams 140-1 to 140-3. For purpose of discussion, the beams 140-1 to 140- 3 are collectively or individually referred to as beam 140.

[0075]

[0057] Correspondingly, in uplink, the second apparatus 120 is an RX device (or a receiver) and the first apparatus 110 is a TX device (or a transmitter), and the first apparatus 110 may transmit uplink transmission to the second apparatus 120 via one or more beams. As illustrated in FIG. 1 , the first apparatus 110 transmits uplink transmission to the second apparatus 120 via the beams 130-1 to 130-3. For purpose of discussion, the beams 130-1 to 130-3 are collectively or individually referred to as beam 130.

[0076]

[0058] Communications in the communication environment 100 may be implemented according to any proper communication protocol(s), comprising, but not limited to, cellular communication protocols of the first generation (1 G), the second generation (2G), the third generation (3G), the fourth generation (4G), the fifth generation (5G), the sixth generation (6G), and the like, wireless local network communication protocols such as Institute for Electrical and Electronics Engineers (IEEE) 802.11 and the like, and / or any other protocols currently known or to be developed in the future. Moreover, the communication may utilize any proper wireless communication technology, comprising but not limited to: Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Frequency Division Duplex (FDD), Time Division Duplex (TDD), Multiple-Input Multiple-Output (MIMO), Orthogonal Frequency Division Multiple (OFDM), Discrete Fourier Transform spread OFDM (DFT-s-OFDM) and / or any other technologies currently known or to be developed in the future. l / l / br Principle and Example Signaling for Communication

[0077]

[0059] Reference is made to FIG. 2, which illustrates a signaling flow 200 of communication in accordance with some embodiments of the present disclosure. For the purposes of discussion, the signaling flow 200 will be discussed with reference to FIG. 1 , for example, by using the first apparatus 110 and the second apparatus 120.

[0078]

[0060] It is to be understood that the operations at the first apparatus 110 and the second apparatus 120 should be coordinated. In other words, the second apparatus 120 and the first apparatus 110 should have common understanding about configurations, parameters and so on. Such common understanding may be implemented by any suitable interactions between the second apparatus 120 and the first apparatus 110 or both the second apparatus 120 and the first apparatus 110 applying the same rule / policy.

[0079]

[0061] In the following, although some operations are described from a perspective of the first apparatus 110, it is to be understood that the corresponding operations should be performed by the second apparatus 120. Similarly, although some operations are described from a perspective of the second apparatus 120, it is to be understood that the corresponding operations should be performed by the first apparatus 110. Merely for brevity, some of the same or similar contents are omitted here.

[0080]

[0062] In the example of FIG. 2, the first apparatus 110 may function as a terminal apparatus and the second apparatus 120 may function as a network apparatus.

[0081]

[0063] As illustrated in FIG. 2, the second apparatus 120 determines (210) a configuration for performing measurement reporting triggered by an event and transmit (220-1) the configuration for performing measurement reporting to the first apparatus 110. As one example embodiment, the configuration may indicate the measurement resources, at least one event that may trigger a measurement reporting. Example event(s) includes but is not limited to:

[0082] • Event-1 : Quality of the current beam is worse than a certain threshold.

[0083] • Event-2: Quality of at least one new beam, such as L1 -RSRP, becomes a threshold value better than the current beam.

[0084] • Event-3: Quality of a new beam is better than a certain threshold.

[0085] • Event-4: Quality of the current beam is worse than a threshold 1 , and quality of at least one new beam is better than a threshold 2.

[0086]

[0064] As for the first apparatus 110, the first apparatus 110 receives (220-2) the configuration for performing measurement reporting triggered by an event from the second apparatus 120. Then, the first apparatus 110 may perform measurements based on the configuration. If at least one pre-configured event is detected, the first apparatus 110 may trigger a measurement reporting procedure (i.e., an event-based measurement report(s) is determined to be transmitted), which causes a pending / triggered measurement reporting procedure.

[0087]

[0065] According to the present disclosure, at least one condition may be pre-defined / pre- configured. Based on the determining that the at least one condition is met, the first apparatus 110 may be configured to or may determine to drop the (event) triggered measurement reporting(s) or cancel the pending trigger.

[0088]

[0066] Specifically, as illustrated in FIG. 2, the first apparatus 110 determines (230) that at least one condition for the measurement reporting triggered by the event is met, and based on the determining that the at least one condition is met, the first apparatus 110 cancels (240) the measurement reporting to the second apparatus 120.

[0089]

[0067] In some example embodiments, a pending / triggered measurement reporting may be cancelled by a plurality of manners. Specifically, the first apparatus 110 may cancel the measurement reporting to the second apparatus 120 by at least one of:

[0090] • dropping a report triggered by the event,

[0091] • cancelling a pending trigger for the measurement reporting triggered by the event,

[0092] • cancelling a transmission of a request indicating that an event has been triggered, or

[0093] • cancelling a transmission of a request for a grant for the measurement reporting.

[0094]

[0068] In some example embodiments, cancelling of the measurement report may mean that the first apparatus 110 (e.g., UE) may determine not to report the triggered report.

[0095]

[0069] In some example embodiments, the at least one condition may be pre-defined. As one example, the at least one condition may be pre-defined by the communication organization (such as 3GPP), or pre-defined by the network operator or service provider. In this way, the at least one condition may be applied as a default configuration and no additional signaling exchanging between the first apparatus 110 and the second apparatus 120 is needed.

[0096]

[0070] Alternatively, in some example embodiments, the at least one condition may be dynamically or semi-statically configured. For example, the second apparatus 120 may determine the at least one condition and then inform at least one condition to the first apparatus. If so, in some example embodiments, the at least one condition may be transmitted together with or separately from the configuration for performing measurement reporting.

[0097]

[0071] In the following, more details about the at least one condition will be discussed.

[0098]

[0072] In some example embodiments, the at least one condition may comprise a condition associated with a transmission configuration indicator, TCI, state change.

[0099]

[0073] Additionally, in some example embodiments, the condition associated with the TCI state for event evaluation may comprise at least one of:

[0100] • that one or more TCI states different from a TCI state for evaluating the event is indicated to the first apparatus 110,

[0101] • that one or more TCI states different from the TCI state for evaluating the event is activated at the first apparatus 110, or

[0102] • that an activation command for one or more TCI states different from the TCI state for evaluating the event is received at the first apparatus 110.

[0103]

[0074] Generally speaking, the first apparatus 110 may be configured with a plurality of TCI states via an RRC signalling. In some example embodiments, the first apparatus 110 may receive a MAC CE used for activating the TCI state(s) in the plurality of configured TCI state. If the number of TCI states activated by the MAC CE is one, the first apparatus 110 may apply the activated TCI state directly. Alternatively, if the number of TCI states activated by then MAC CE is larger than one, the first apparatus 110 needs to receive DCI used for indicating a TCI to be applied.

[0104]

[0075] In one example embodiment, the first apparatus 110 may be configured to drop / cancel the event-triggered report (or cancel the pending trigger for the report) if the first apparatus 110 is indicated with (either DCI based or MAC CE based indication) a new TCI state(s) associated with the event triggered reporting. In one example, the RS included in the TCI state may be used as reference resource for event triggered reporting. In another example, the TCI state or the RS or the quasi-colocation (QCL) source RS of the RS included in the TCI State may be used for event evaluation.

[0105]

[0076] In another example embodiment, the first apparatus 110 may be configured to drop / cancel the event-triggered report (or cancel the pending trigger for the report) if the first apparatus 110 is activated with a new TCI state(s) associated with the event triggered reporting. If there is only one activated TCI state, the activated TCI becomes the indicated TCI state. In one example the RS (or QCL source RS of the RS) included in the TCI state may be used as reference resource for event triggered reporting.

[0106]

[0077] In further example embodiment, the first apparatus 110 may be configured to drop / cancel the event-triggered report (or cancel the pending trigger for the report) if the first apparatus 110 receives (new) activation command for one or more TCI states associated with the event triggered reporting. As an example, the first apparatus 110 receives activation for a set of TCI states for indication. In some embodiments, the TCI state(s) may be unified TCI state(s). In some embodiments, the TCI state(s) may include one or more of the following: joint DL / UL TCI state(s), or separate DL / UL TCI state(s). RSs included in the one or more activated / indicated TCI states may change causing the change of reference signals for event evaluation.

[0107]

[0078] According to the above example processes, it can be seen, in a case that the TCI state changes, the pending / triggered measurement reporting may be unnecessary (i.e., the reported information becomes useless for the second apparatus 120). Thus, the measurement reporting may be cancelled.

[0108]

[0079] In some example embodiments, the at least one condition may comprise a condition associated with a beam failure.

[0109]

[0080] Additionally, in some example embodiments, the condition associated with a beam failure comprises at least one of:

[0110] • that the beam failure is detected,

[0111] • that the first apparatus 110 determines to trigger a beam failure recovery procedure for the beam failure, or

[0112] • that a beam failure recovery procedure for the beam failure is triggered.

[0113]

[0081] In some example embodiments, the at least one condition may comprise a condition associated with another event being triggered. In one example, triggering of another event (e.g. a reporting event) may be a condition to drop / cancel a previously triggered event.

[0114]

[0082] In some example embodiments, the at least one condition may comprise a condition associated with a maximum permissible exposure (MPE) or MPE reporting event. In a case of an MPE event, the first apparatus 110 (e.g., UE) may determine that power backoff / reduction applied for uplink transmission has exceeded or may exceed a configured threshold level. The MPE event may be reported to network. In some example embodiments, this event may cause the second apparatus 120 (e.g., NW) to perform beam management actions, i.e. reporting / beam changed.

[0083] In some example embodiments, the at least one condition may comprise a condition associated with (consistent) listen before talk (LBT) failure on uplink. The (consistent) LBT failure may be detected on a UL BWP. The MAC layer of the first apparatus 110 may counter LBT failure indications from lower layers to determine whether an LBT failure has occurred.

[0115]

[0084] In one example embodiment, the first apparatus 110 may be configured to drop / cancel the event-triggered report (or cancel the pending trigger for the report) if the first apparatus 110 determines to trigger beam failure recovery procedure or the first apparatus 110 determines that a beam failure recovery procedure has been triggered. That is because the beam failure recovery procedure may reflect that the current channel condition is not good, and thus the measurement reporting seems to be redundancy.

[0116]

[0085] In some example embodiments, the at least one condition may comprise a condition associated with frequency resources configured for the first apparatus 110.

[0117]

[0086] Additionally, in some example embodiments, the condition associated with the frequency resources configured for the first apparatus 110 comprises at least one of:

[0118] • that a command to switch from a bandwidth part to another bandwidth part is received at the first apparatus 110,

[0119] • that the first apparatus 110 determines to perform bandwidth part switching,

[0120] • that bandwidth part switching is performed, or

[0121] • that a bandwidth part used by the first apparatus 110 for evaluating the event is an initial bandwidth part, or

[0122] • that a bandwidth part used by the first apparatus 110 for evaluating the event is a specific bandwidth part.

[0123]

[0087] In one example embodiment, the first apparatus 110 may be configured to drop / cancel the event-triggered report (or cancel the pending trigger for the report) if the first apparatus 110 receives BWP switching command to another BWP. In one example embodiment, the BWP switching may be an UL BWP switching. Alternatively, or in addition, in another example embodiment, the BWP switching may be a DL BWP switching.

[0124]

[0088] In another example embodiment, the first apparatus 110 may be configured to drop / cancel the event-triggered report (or cancel the pending trigger for the report) if the first apparatus 110 determines to switch BWP based on the BWP switching timer.

[0125]

[0089] In a further example embodiment, the first apparatus 110 may be configured to drop / cancel the event-triggered report (or cancel the pending trigger for the report) if the first apparatus 110 determines that the BWP is an initial BWP.

[0090] In some example embodiments, the at least one condition may comprise at least one of: a change in a reference resource used for evaluating the event, a condition associated with triggering of a further event, a condition associated with a maximum permissible exposure of the first apparatus, or a condition associated with a listen before talk failure at the first apparatus.

[0126]

[0091] In one example embodiment, the first apparatus 1 10 may be configured to drop / cancel the event-triggered report (or cancel the pending trigger for the report) if at least one reference resource used for evaluation of the event is changed (e.g., TCI state switch). In one example, the configuration / activation of channel measurement resource sets (SSB or CSI-RS resources or resource sets) used event evaluation changes.

[0127]

[0092] In some example embodiments, the at least one condition may comprise that a data or control information transmission to the second apparatus 120 is at least partially overlapped with a resource for requesting a grant for the measurement reporting.

[0128]

[0093] In one example embodiment, when PUSCH / PUCCH carrying hybrid automatic repeat request-acknowledgement (HARQ-ACK) of serving cell overlaps in the same symbol as resource of UL signal (e.g. scheduling request, SR,) / reference signal (RS) (e.g. UL SRS), the first apparatus 1 10 shall drop transmission of resource of UL sig nal / RS to request event triggering report.

[0129]

[0094] In another example embodiment, when PUSCH / PUCCH configured with repetition overlaps fully / partly with the same symbol(s) resource of UL signal (e.g. SR) / reference signal (RS) (e.g. UL SRS), the first apparatus 1 10 shall drop transmission of resource of UL signal / RS to request event triggering report.

[0130]

[0095] In this way, the uplink transmission with higher priority many be guaranteed.

[0131]

[0096] According to the above example processes, by cancelling unnecessary reporting, the uplink resource waste is avoided, and the power, battery, processing resource of the first apparatus 1 10 may be saved accordingly.
