METHODS AND APPARATUS FOR EVENT-TRIGGERED CHANNEL STATE INFORMATION REPORTING IN MOBILE COMMUNICATIONS

CROSS REFERENCE TO RELATED PATENT APPLICATION (S)

The present disclosure is part of a non-provisional application claiming the priority benefit of U.S. Patent Application No. 63/554, 247, filed 16 February 2024, U.S. Patent Application No. 63/566,414, filed 18 March 2024, U.S. Patent Application No. 63/567,486, filed 20 March 2024, U.S. Patent Application No. 63/641,432, filed 02 May 2024, U.S. Patent Application No. 63/641,976, filed 03 May 2024, and U.S. Patent Application No. 63/641,977, filed 03 May 2024. The contents of aforementioned applications are herein incorporated by reference in their entirety.

TECHNICAL FIELD

The present disclosure is generally related to mobile communications and, more particularly, to event-triggered channel state information (CSI) reporting with respect to user equipment (UE) and network apparatus in mobile communications.

BACKGROUND

Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.

In conventional CSI reporting procedure, the CSI reporting and the corresponding uplink (UL) resource for carrying the CSI report are always network (NW) -triggered or NW-scheduled. For example, a periodic CSI report (or periodic CSI reports) is transmitted on the pre-configured resource (s) (e.g., physical uplink control channel (s) (PUCCH (s) ) . In another example, a semi-persistent report (or semi-persistent reports) can be transmitted on the pre-configured resource (s) (e.g., PUCCH (s) or CG-PUSCH (s) ) which is activated by a downlink control information (DCI) . In another example, an aperiodic report (or aperiodic reports) is transmitted on the dynamically-allocated resource (s) (e.g., dynamic grant (DG) -PUSCH (s) ) which is scheduled by a DCI.

The NW-triggered or NW-scheduled CSI reporting needs to make a trade-off between the latency and the overhead, since NW may not always be aware of necessity to trigger/activate the CSI reporting. For example, more reporting resource allocation can shorten the reporting latency, but it could cause lower resource efficiency. In addition, less reporting resource allocation can achieve higher resource efficiency, but it could increase the reporting latency.

Accordingly, how to perform the CSI reporting procedure more efficiently to improve the reporting performance becomes an important issue for the newly developed wireless communication network. Therefore, there is a need to provide proper schemes to perform the CSI reporting.

Overview

Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and/or solutions pertaining to event-triggered reporting with respect to user equipment and network apparatus in mobile communications. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.

FIG. 1 illustrates an example scenario 100 of a communication environment in which various solutions and schemes in accordance with the present disclosure may be implemented. Scenario 100 involves a UE 110 in wireless communication with a network 120 (e.g., a wireless network including an NTN and a TN) via a terrestrial network node 125 (e.g., an evolved Node-B (eNB) , a Next Generation Node-B (gNB) , or a transmission/reception point (TRP) ) and/or a non-terrestrial network node 128 (e.g., a satellite) . For example, the terrestrial network node 125 and/or the non-terrestrial network node 128 may form a non-terrestrial network (NTN) serving cell for wireless communication with the UE 110. In some implementations, the UE 110 may be an IoT device such as an NB-IoT UE or an enhanced machine-type communication (eMTC) UE (e.g., a bandwidth reduced low complexity (BL) UE or a coverage enhancement (CE) UE) . In such communication environment, the UE 110, the network 120, the terrestrial network node 125, and the non-terrestrial network node 128 may implement various schemes pertaining to improved event-triggered reporting (or event-driven reporting, or UE-initiated reporting, or UE-triggered reporting) procedure in accordance with the present disclosure, as described below. It is noteworthy that, while the various proposed schemes may be individually or separately described below, in actual implementations some or all of the proposed schemes may be utilized or otherwise implemented jointly. Of course, each of the proposed schemes may be utilized or otherwise implemented individually or separately.

According to the implementations of the present disclosure, an apparatus (e.g., the UE 110) may receive a report configuration from a network node (e.g., the terrestrial network node 125 or the non-terrestrial network node 128) . The report configuration may be associated with at least one of an event, a reference signal (RS) resource set, and a report configuration index. Then, the apparatus may determine whether the event is triggered.

In an example, the signal quality information may comprise a reference signal received power (RSRP) value or a signal to interference plus noise ratio (SINR) value for at least one candidate beam (e.g., new beam or suggested beam) . In another example, the signal quality information may comprise an RSRP value or an SINR value of an RS resource associated with a transmission configuration indicator (TCI) state for a current beam. In an implementation, the TCI state may be an indicated TCI state, e.g., the TCI state is indicated by the network node. In another implementation, the TCI state may be an activated TCI state, e.g., the TCI state is activated by the network node. In addition, in an example, the RS resource may be a quasi co-location (QCL) RS in the TCI state in an event that the RS resource set comprises at least one channel state information-RS (CSI-RS) resource.

Under a sixth proposed scheme for the event in accordance with the present disclosure, the event may be defined as that the quality (or qualities) of the new beam (or beams) is a threshold value higher (or better) than the quality of at least one current beam. That is, in an event that the quality (or qualities) of the new beam (or beams) is the threshold value higher (or better) than the quality of the at least one current beam, the event is triggered.

The report may further comprise the RS index (or RS indexes) of the suggested beam (or suggested beams) . The suggested beam (or suggested beams) may be determined by the apparatus according to a set of the RS resource set associated with the report configuration.

In addition, in the sixth proposed scheme, the report may further comprise a report configuration index (e.g., a report configuration ID) associated with the report configuration from the network node. The report may further comprise a CC index (e.g., a CC ID) . According to the sixth proposed scheme, the current beam (or current beams) may be obtained according to the RS resource (or RS resources) associated with the TCI state (or TCI states) in the active TCI state list. The new beam (or new beams) may be obtained according to the RS resource (or RS resources) associated with the TCI state (or TCI states) which is not in the active TCI state list. The apparatus may determine the association between the RS resource (or RS resources) and the TCI state (or TCI states) based on the source RS for QCL Type-D or the radio resource control (RRC) configuration.

In an implementation in accordance with the present disclosure, the RS resource set may comprise at least one SSB resource or at least one CSI-RS resource. Specifically, the RS resource (or measurement RS resource) for the current beam may be determined according to the QCL RS for an indicated TCI state. The RS resource determined according to the QCL RS for an indicated TCI state may comprise an SSB, a CSI-RS for tracking, or a CSI-RS for beam measurement (BM) . In addition, the RS resource or RS resources (or measurement RS resource or RS resources) for the new beam or new beams may be provided through an RRC configuration. The RS resource provided through the RRC configuration may comprise an SSB or a CSI-RS for BM. The type (e.g., SSB or CSI-RS) of RS resource for the current beam and the type (e.g., SSB or CSI-RS) of the RS resource (or RS resources) for the new beam (or new beams) may be the same. In an example, if the type of the RS resource for the current beam or new beam (or new beams) is determined as CSI-RS, the RS resource for the current beam may be the CSI-RS which is the QCL Type-D source RS in the indicated TCI state or may be a CSI-RS provided in the corresponding report configuration.

The RS resource set associated with the report configuration may comprise at least one SSB resource or at least one CSI-RS resource. Therefore, the RS resource (or measurement RS resource) of the current beam may be a CSI-RS or an SSB determined according to the QCL RS (or QCL RSs) of the indicated TCI state. In addition, the RS resource (or measurement RS resource) or the RS resources (or measurement RS resources) of the new beam may be a CSI-RS (or CSI-RSs) or an SSB (or SSBs) . The RS resource (or measurement RS resource) of the current beam being a CSI-RS or a SSB may be determined according to the type of the RS resource (or measurement RS resource) or RS resources (measurement RS resources) for the new beam (or new beams) . If the RS resource (or RS resources) of new beam (or new beams) is the CSI-RS (or CSI-RSs) , the RS resource of the current beam may be the CSI-RS determined according to the QCL RS (or QCL RSs) of the indicated TCI state. If the RS resource (or RS resources) of new beam (or new beams) is the SSB (or SSBs) , the RS resource of the current beam may be the SSB determined according to the QCL RS (or QCL RSs) of the indicated TCI state. In an implementation, the network node may provide a configured set of downlink (DL) -RS (or DL-RSs) (e.g., the RS resource set) in the report configuration associated with the event. If the configured set of DL-RS (or DL-RSs) only comprises CSI-RS (or CSI-RSs) , the RS (or RSs) of the new beam (or new beams) may be the CSI-RS (or CSI-RSs) in the configured set. If the configured set of DL-RS (or DL-RSs) only comprises SSB (or SSBs) , the RS resource (or RS resources) of the new beam (or new beams) may be the SSB (or SSBs) in the configured set.

The apparatus may be configured with a set of reporting transmission occasions (RTOs) for one or more report configurations. Therefore, how to determine that the report (or repots) on the RTO corresponds to which report configuration (or report configurations) in which CC may be an issue. For example, in an event that the apparatus is on an RTO in a first CC, the apparatus may transmit one or more reports corresponding to more than one report configurations in the first CC, e.g., the RTO is provided through a physical uplink control channel (PUCCH) resource configured in the first CC. In another example, in an event that the apparatus is on an RTO in a second CC, the apparatus may transmit one or more reports corresponding to more than one report configurations in more than one CCs, e.g., the RTO may be provided through a configured grant (CG) physical uplink shared channel (PUSCH) in the second CC. The more than one CCs may comprise or may not comprise the second CC.

In order to resolve the issue, according to an implementation in accordance with the present disclosure, the report may comprise the report configuration index associated with the report configuration. Specifically, the report (e.g., a CSI report) may correspond to the report configuration (e.g., a CSI report configuration) . The apparatus may provide the report configuration index associated with the report configuration to the network node through the report. The report configuration index may be an ID comprised in the report configuration. The report configuration index may be determined according to the order of the report configuration among all report configurations associated with the same set of reporting transmission occasions (RTOs) .

In addition, according to an implementation in accordance with the present disclosure, the report may comprise a CC index. Specifically, the report (e.g., a CSI report) may correspond to the report configuration (e.g., a CSI report configuration) . The apparatus may provide the CC index to the network node through the report. The CC index may be an ID for the CC configured with the report configuration.

Additional Notes

The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected" , or "operably coupled" , to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" , to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.

Further, with respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to, ” the term “having” should be interpreted as “having at least, ” the term “includes” should be interpreted as “includes but is not limited to, ” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an, " e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more; ” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of "two recitations, " without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B. ”

From the foregoing, it will be appreciated that various implementations of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various implementations disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
