METHODS AND APPARATUS FOR CHANNEL STATE INFORMATION REPORTING IN MOBILE COMMUNICATIONSCROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0001] The present disclosure is part of a non-provisional application claiming the priority benefit of U.S. Patent Application No. 63 / 627,143, filed 31 January 2024, U.S. Patent Application No. 63 / 641,445, filed 02 May 2024, U.S. Patent Application No. 63 / 642,945, filed 06 May 2024, and U.S. Patent Application No. 63 / 645,207, filed 10 May 2024. The contents of aforementioned applications are herein incorporated by reference in their entirety.TECHNICAL FIELD
[0002] The present disclosure is generally related to mobile communications and, more particularly, to channel state information (CSI) reporting with respect to user equipment (UE) and network apparatus in mobile communications.BACKGROUND
[0003] 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.
[0004] 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 configured grant physical uplink shared channel (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.
[0005] 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.
[0006] Accordingly, how to perform the CSI reporting procedure more efficiently to improve the CSI reporting 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.SUMMARY

That is, the following summary is provided to introduce concepts, highlights, benefits and advantages of the novel and non-obvious techniques described herein. Select implementations are further described below in the detailed description.

[0021] Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0022] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to channel state information (CSI) 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.
[0023] 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 CSI 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.
[0024] Under a first proposed scheme for the CSI reporting procedure in accordance with the present disclosure, an apparatus (e.g., the UE 110) may receive a CSI report configuration (e.g., an event-triggered CSI reporting configuration, an event-driven CSI reporting configuration or a UE-initiated CSI reporting configuration) from a network node (e.g., the terrestrial network node 125 or the non-terrestrial network node 128) . The CSI report configuration may be associated with at least one event. Then, the apparatus may determine whether a reporting (e.g., an event-triggered CSI reporting, an event-driven CSI reporting, or a UE-initiated CSI reporting) for the CSI report configuration is triggered based on a trigger condition of the at least one event. The apparatus may transmit an indication (e.g., an uplink (UL) indication) to the network node to request a resource for the reporting in an event that the reporting for the CSI report configuration is triggered. The indication may be a one-bit / multi-bits indication on a dedicated periodic physical uplink control channel (PUCCH) resource using PUCCH format 0 / 1. In an example, the indication may be an uplink control information (UCI) . In another example, the indication may be a scheduling request (SR) .
[0025] After the apparatus transmit the indication to the network node, the apparatus may receive a downlink control information (DCI) indicating the resource for the reporting from the network node. Then, the apparatus may transmit a CSI report for the CSI report configuration to the network node in the resource (e.g., a physical uplink shared channel (PUSCH) ) indicated by the DCI. The CSI report may be a UCI in the PUSCH.
[0026] The DCI may indicate a trigger state (e.g., an aperiodic trigger state) through a CSI request field, and schedules a PUSCH as the resource for the reporting. Specifically, when the apparatus receives the DCI from the network node, according to the CSI request field in the DCI, the apparatus may determine whether the resource scheduled in the DCI is used for the reporting.
[0027] The trigger state (e.g., the aperiodic trigger state) indicated in the DCI may be associated with a plurality of CSI report configurations (e.g., a first CSI report configuration and a second CSI report configuration) . The UE may determine which CSI reports can use the resource (e.g., PUSCH) according to the trigger state indicated in the CSI request field of the DCI. An association between the trigger state and the CSI report configuration may be determined according to a radio resource control (RRC) configuration. FIG. 2 illustrates an example scenario 200 of the information element CSI-AperiodicTriggerStateList in the RRC configuration in accordance with an implementation of the present disclosure. For example, referring to FIG. 2, a list of trigger states may be configured according to the RRC configuration through the parameter (or information element (IE) ) CSI-AperiodicTriggerStateList which may comprise a plurality of trigger states (e.g., 128 trigger states) . The associations between the trigger states and the CSI reporting configurations may be indicated by associatedReportConfigInfoList comprising a list of CSI-AssociatedReportConfigInfo. In an example, the aperiodic trigger state may be associated with at least one CSI report configuration for an event-triggered CSI reporting. In another example, the aperiodic trigger state may be associated with at least one CSI report configuration for an event-triggered CSI reporting and associated with at least one CSI report configuration for an aperiodic CSI reporting.
[0028] According to an implementation under the first proposed scheme of the present disclosure, the RRC configuration may comprise a CSI report configuration identification (ID) and a serving cell index. For example, in each CSI-AssociatedReportConfigInfo, a CSI-ReportConfigId may be provided. In addition, in a CSI-AssociatedReportConfigInfo, a serving cell index may be provided. In an event that a serving cell index is provided in a CSI-AssociatedReportConfigInfo, the CSI-ReportConfigId provided in the same CSI-AssociatedReportConfigInfo may refer to a CSI report configuration configured in (CSI-MeasConfig of) the serving cell corresponding to the serving cell index. In an event that a serving cell index is not provided in a CSI-AssociatedReportConfigInfo, the CSI-ReportConfigId provided in the same CSI-AssociatedReportConfigInfo may refer to a CSI report configuration configured in (CSI-MeasConfig of) the serving cell where the trigger state (e.g., aperiodic trigger state) is configured.
[0029] According to an implementation under the first proposed scheme of the present disclosure, the CSI request field with bits in the DCI may indicate a trigger state, where NTS ∈ {0, 1, 3, 4, 5, 6} may be configured according to the RRC configuration through a parameter reportTriggerSize. In an event that the number of the configured trigger states is greater than the apparatus may receive a sub-selection indication (e.g., a medium-access-control control-elements (MAC CE) ) used to map up to trigger states to the codepoints of the CSI request field in the DCI. In an event that the number of the configured trigger states is less than or equal to the CSI request field in the DCI may directly indicate the trigger state. When all the bits of CSI request field in the DCI are set to zero, no reporting for any CSI report configuration is requested.
[0030] Under a second proposed scheme for the CSI reporting procedure in accordance with the present disclosure, an apparatus (e.g., the UE 110) may receive a CSI report configuration (e.g., an event-triggered CSI reporting configuration, an event-driven CSI reporting configuration or a UE-initiated CSI reporting configuration) from a network node (e.g., the terrestrial network node 125 or the non-terrestrial network node 128) . The CSI report configuration may be associated with at least one event. In addition, the apparatus may receive a transmission occasion configuration from the network node. The transmission occasion configuration may be pre-defined by the network node. The transmission occasion configuration may indicate at least one UL resource (e.g., PUSCH resource or a configured grant (CG) -PUSCH) . Specifically, the UE can know when the UL resource appear in the time-domain according to the transmission occasion configuration, and then the UE can use the UL resource for a reporting (e.g., an event-triggered CSI reporting, an event-driven CSI reporting, or a UE-initiated CSI reporting) .
[0031] The apparatus may determine whether a reporting (e.g., an event-triggered CSI reporting, an event-driven CSI reporting, or a UE-initiated CSI reporting) for the CSI report configuration is triggered based on a trigger condition of the at least one event. The apparatus may transmit an indication (e.g., a UL indication) to the network node to reserve or occupy a transmission occasion of the at least one UL resource in an event that the reporting for the CSI report configuration is triggered. Specifically, because the UL resource pre-configured in the transmission occasion configuration may be configured to more than one UE (i.e., different CSI report configurations may be associated to the same UL resource or different UL resources) , the apparatus may need to transmit the indication to the network node to inform the network that it will use the transmission occasion for the reporting. Then, the network node may reserve the transmission occasion for the apparatus. The indication may be a one-bit / multi-bits indication on a dedicated PUCCH resource using PUCCH format 0 / 1. In an example, the indication may be a UCI. In another example, the indication may be a scheduling request. After the apparatus transmits the indication to the network node, the apparatus may transmit the PUSCH carrying a CSI report for the CSI report configuration on the transmission occasion of the at least one UL resource. The CSI report may be a UCI in the PUSCH.
[0032] The transmission occasion reserved by the indication may be the most recent pre-configured occasion whose earliest symbol starts after an offset time from a latest symbol of the indication. The offset time may be determined according to an RRC configuration. For example, in an event that the apparatus transmits the indication to the network node at time a point n, the apparatus may transmit the CSI report (or perform the beam reporting) on the first pre-configured occasion after an offset time Toffset, i.e., the apparatus may transmit the CSI report after the time point n+Toffset.
[0033] According to an implementation under the second proposed scheme of the present disclosure, the apparatus may be always allowed to transmit a PUSCH or a physical uplink control channel PUCCH on the transmission occasion of the at least one UL resource, i.e., the transmission occasion is scheduled only for the apparatus. According to another implementation under the second proposed scheme of the present disclosure, in order to use the UL resource more efficiently, the apparatus may be allowed to transmit a PUSCH or a physical uplink control channel PUCCH on the transmission occasion of the at least one UL resource in an event that the transmission occasion of the at least one UL resource is reserved by the indication transmitted by the apparatus. For example, the apparatus may transmit a PUSCH carrying the CSI report on the transmission occasion of the at least one PUSCH resource in an event that the transmission occasion of the at least one PUSCH resource is reserved by the indication transmitted by the apparatus. In other words, the apparatus may not be allowed to transmit any PUSCH or PUCCH on the transmission occasion of the at least one UL resource in an event that the transmission occasion of the at least one UL resource is not reserved by the apparatus. For example, the apparatus may be not allowed to transmit any PUSCH on the transmission occasion of the at least one PUSCH resource in an event that the transmission occasion of the at least one PUSCH resource is not reserved by the indication transmitted by the apparatus. That is, in the implementation of the present disclosure, in an event that the apparatus does not transmit the indication to the network node to reserve the transmission occasion, the UE cannot use the transmission occasion.

[0086] 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.
[0087] 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.
[0088] 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. ”
