Description
METHODS AND APPARATUS OF USER EQUIPMENT CAPABILITY 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 / 714,929, filed 1 November 2024, the content of which herein being incorporated by reference in its entirety.TECHNICAL FIELD
[0002] The present disclosure is generally related to mobile communications and, more particularly, to user equipment capability reporting 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 mobile communications, when a network needs radio access capability information or additional radio access capability information from a user equipment (UE) , it initiates a UE capability transfer procedure by sending a UE capability enquiry message to the UE that has an established radio resource control (RRC) connection with the network. With the continuous evolution of cellular technology, the size of the UE capability has grown significantly due to the introduction of new features and an increased number of aggregated carriers. To manage this large data size, segmentation was introduced, which breaks down the capability information into smaller chunks. However, this method comes at a cost: it introduces a notable delay for the base station (BS) to receive and reassemble all the segments, a problem that is often worsened by the BS that configure limited uplink resources for the transfer. An alternative approach to avoid segmentation is for the BS to query one radio access technology (RAT) capability at a time with a reduced number of requested bands. While this method prevents segmentation, it leads to frequent capability transfers that do not fully solve the underlying problem, as a substantial amount of the capability content remains. As both current methods of handling large UE capabilities cause inefficiencies, this highlights the need for a more efficient and dynamic method for UE capability reporting.SUMMARY

[0019] 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
[0020] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to user equipment (UE) capability reporting 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.
[0021] 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 wireless network (e.g., an LTE network, a 5G / NR network, an IoT network, or a 6G network) consisting of an access network 120 and a core network 130. The UE 110 may be a smart phone, a wearable device, an IoT device, a customer premises equipment (CPE) for fixed wireless access (FWA) (i.e., a CPE / FWA device) , and a tablet, etc. Alternatively, the UE 110 may be a notebook (NB) or personal computer (PC) inserted or installed with a data card which includes a modem and radio frequency (RF) transceiver (s) to provide the functionality of wireless communication. In one embodiment, the access network 120 is connected to the core network 130 by means of the NG interface, more specifically to a user plane function (UPF) by means of the NG user-plane part (NG-u) , and to an access and mobility management function (AMF) by means of the NG control-plane part (NG-c) . The access network 120 may include a base station (BS) 121, which may be connected to multiple UPFs / AMFs for the purpose of load sharing and redundancy. In addition, the core network may include other entities, such as a session management function (SMF) and a unified data management (UDM) , etc. In some embodiments, the access network 120 may include multiple BSs, each of which may provide communication coverage for a geographic coverage area where communications with the UE 110 is supported.
[0022] To provide the best possible service, the network may initiate a UE capability reporting process. Current UE capability reporting methods present a fundamental trade-off between signaling overhead and network efficiency, often leading to performance delays. For instance, during the initial registration process, the AMF must acquire specific UE radio capabilities-such as support for IP Multimedia Subsystem (IMS) voice over packet switched (PS) session-by triggering a capability transfer procedure, which in turn extends the overall registration time. Similarly, to reduce signaling overhead, a BS might initially request capabilities for only a limited set of bands. However, if the UE later hands over to a new BS that requires capabilities of different set of bands for mobility or advanced features like carrier aggregation (CA) or dual connectivity (DC) , the new BS must re-trigger the capability transfer. This causes a delay, preventing the UE from quickly accessing higher data rates. In the present disclosure, a more dynamic and efficient solution for UE capability reporting is introduced. Specifically, the efficiency of UE capability reporting is enhanced by categorizing the UE capability into different types. For instance, a basic type may be defined as having a small size and being able to be sent first to avoid blocking any follow-on procedures (e.g., packet data network (PDN) activation, protocol data unit (PDU) activation, CA configuration, DC configuration, measurement configuration for handover, etc. ) . An advanced type, in contrast, may have a larger size and require segmentation, with a lesser impact on follow-on procedures. In scenario 100, the BS 121 may indicate whether the UE 110 should transfer only the basic capability or the advanced capability. If the BS 121 does not specify a type, the UE 110 reports its complete (full) capability by default. For example, in scenario 210 of FIG. 2, the capabilityRequestType element in the capability enquiry message may specify either a basic type or an advanced type. When the capabilityRequestType element does not specify a type, it implies a request for a complete type. This design would reduce signaling overhead, especially if the network only queries for the advanced capability after handover. Upon receiving the capability enquiry message, the UE 110 determines the requested capability type and reports its capabilities based on that determination. As illustrated in scenario 220 of FIG. 2, the UE 110 may include a container type within the UE-CapabilityRAT-Container to specify which parts are present in the message. The message is transmitted to the BS 121.
[0023] In one embodiment, the UE capabilities included in the basic type and advanced type are predefined. As shown in scenario 310 of FIG. 3A, static (or constant) capabilities and serving band capabilities are categorized as the basic type, while dynamic capabilities are categorized as the advanced type. Additionally, any new advanced features introduced in a later release of a technology standard may also be categorized as the advanced type. For instance, the underlined features in scenario 310 are all categorized as the advanced type. In another embodiment, the UE capabilities included in the basic type and advanced type are specified by the base station or other network node. As shown in FIG. 3B, the content of the basic type and advanced type may be indicated in a UE capability enquiry message (e.g., UECapabilityEnquiry message) . For example, in scenario 321, the content of the basic type and advanced type may be common and indicated by the UECapabilityEnquiry message. Alternatively, in scenario 322, the content of the basic type and advanced type may be radio access technology (RAT) -dependent and indicated by an element or parameter, such as UE-CapabilityRAT-Request, in the UECapabilityEnquiry message.
[0024] FIGs. 4A to 4C are diagrams depicting example scenarios under schemes in accordance with implementations of the present disclosure. When a UE receives a capability enquiry message, it determines the type of requested capability and reports the corresponding UE capability. If the capability's size exceeds that of a single message (e.g., a single radio resource control (RRC) message) , the capability may be segmented, provided that message segmentation is enabled.
[0025] In scenario 400a, upon receiving a capability enquiry message indicating a basic type, the UE reports its basic UE capability to the BS. As the BS queries only the basic UE capability, the UE does not need to report the advanced UE capability with a larger size. Upon receiving the basic UE capability, the BS may store the received capability data and proceed with one or more follow-on procedures, such as PDN / PDU activation, CA / DC configuration, or measurement configuration for handover.
[0026] In scenario 400b, upon receiving a capability enquiry message indicating an advanced type, the UE reports its advanced UE capability to the BS. Specifically, the UE may determine whether the advanced UE capability can be sent in a single message (e.g., a single RRC message) or in separate messages based on its size and complexity. In scenario 400b, where RRC uplink (UL) message segmentation is enabled and the size of the advanced UE capability is larger than the maximum supported size of a packet data convergence protocol (PDCP) service data unit (SDU) , the UE may initiate the UL message segment transfer procedure to report the advanced UE capability. Upon receiving the advanced UE capability, the BS may update the stored capability data and proceed with further procedures.
[0027] In scenario 400c, upon receiving a capability enquiry message indicating a complete type or no type at all, the UE reports its complete UE capability to the BS. The UE first determines if the complete UE capability can be sent in a single message. If the size exceeds a single message size (e.g., that of a single RRC message) , the UE reports the basic UE capability first. Once the BS receives the basic UE capability, it may proceed with one or more follow-on procedures without waiting for the advanced UE capability. After reporting the basic capability, the UE may then initiate the UL message segment transfer procedure to report the advanced UE capability. Alternatively, if the complete UE capability does not exceed a single message size, the UE may report its complete UE capability at once. When receiving the complete UE capability, the BS may store the received data and proceed with the follow-on procedures.
[0028] In the foregoing embodiments, the term "capability" should be interpreted as "one or more capabilities" . By categorizing UE capabilities into different types, the efficiency of the network system is enhanced, as capability reporting can be tailored to a specific request of the network node.

[0056] 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.
[0057] 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.
[0058] 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. ”
