Abstract
Description
METHODS AND APPARATUS OF CAPABILITY REQUEST FILTER PROVISIONING IN WIRELESS 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 / 745,393, filed 15 January 2025, 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 capability request filter provisioning in wireless 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 fifth-generation (5G) new radio (NR) mobile communication systems, user equipment (UE) capability reporting is a fundamental procedure by which a network obtains information regarding radio access capabilities supported by a UE. Such capability information is used by the network to determine appropriate radio configurations and to support various network operations, including access control, mobility management, and session establishment. As wireless communication systems continue to evolve, the amount and complexity of UE capability information have increased significantly compared to earlier systems, placing greater demands on both signaling efficiency and processing capability.
[0005] In existing 5G NR systems, a UE typically reports its capability information in response to a UE capability enquiry message transmitted by the network after a radio resource control (RRC) connection is established. Prior to receiving the UE capability enquiry message, the UE generally does not have information indicating which portions of its capability information are actually required by the network. As a result, the UE is required to perform capability construction and preparation within a limited time window following receipt of the enquiry message, which may increase processing pressure at the UE.
[0006] As the complexity of UE capability information continues to grow, the processing workload associated with constructing and preparing such information may exceed a processing time tolerated by system specifications in certain scenarios. The timing constraint of starting capability information construction limits the ability of the UE to efficiently prepare capability information and may lead to further delayed completion of capability reporting procedures. Consequently, there is a need for an improved mechanism that enables more efficient preparation of UE capability information while maintaining compatibility with existing UE capability reporting procedures.SUMMARY
[0007] The following summary is illustrative only and is not intended to be limiting in any way. 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. Thus, the following summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.
[0008] An objective of the present disclosure is to propose solutions or schemes that address the aforementioned issues pertaining to capability request filter provisioning in wireless communications.
[0009] In one aspect, a method may involve a user equipment (UE) receiving a capability request filter information from a network node prior to a UE capability reporting procedure. The capability request filter information indicates a capability information requested by the network node. The method may also involve the UE constructing a UE capability information based on the capability request filter information prior to the UE capability reporting procedure.
[0010] In another aspect, a user equipment (UE) may comprise a transceiver which, during operation, wirelessly communicates with a network node of a wireless network. The UE may also comprise a processor communicatively coupled to the transceiver. The processor, during operation, may perform operations comprising receiving, via the transceiver, a capability request filter information from a network node prior to a UE capability reporting procedure. The capability request filter information indicates a capability information requested by the network node. The processor, during operation, may also perform operations comprising constructing a UE capability information based on the capability request filter information prior to the UE capability reporting procedure.
[0011] In yet another aspect, a method may involve a network node transmitting a capability request filter information to a user equipment (UE) prior to a UE capability reporting procedure. The capability request filter information indicates a capability information requested by the network node, and the capability request filter information is used by the UE to construct a UE capability information prior to the UE capability reporting procedure. The method may also involve the network node initiating the UE capability reporting procedure after transmitting the capability request filter information.
[0012] It is noteworthy that, although description provided herein may be in the context of certain radio access technologies, networks and network topologies such as Long-Term Evolution (LTE) , LTE-Advanced, LTE-Advanced Pro, 5th Generation (5G) , New Radio (NR) , Internet-of-Things (IoT) and Narrow Band Internet of Things (NB-IoT) , Industrial Internet of Things (IIoT) , and 6th Generation (6G) , the proposed concepts, schemes and any variation (s) / derivative (s) thereof may be implemented in, for and by other types of radio access technologies, networks and network topologies. Thus, the scope of the present disclosure is not limited to the examples described herein.BRIEF DESCRIPTION OF THE DRAWINGS

[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 capability request filter provisioning 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 user equipment (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 are supported.
[0024] In scenario 100, carrier aggregation (CA) and dual connectivity (DC) are supported. Both CA and DC are technologies that allow a device (e.g., UE 110) to transmit data using multiple frequency bands simultaneously. Specifically, CA allows a device to connect to multiple frequency blocks, called component carriers (CCs) , from a single base station, while DC allows a device to connect to two separate base stations (or "nodes" ) at the same time. The access network 120 may configure CA and / or DC to the UE 110; this requires the access network 120 to know exactly which specific band combinations the UE 110 supports. In the present disclosure, to prevent too many unnecessary band combinations reported by the UE 110 and to ensure the processing of reported band combinations more efficiently, the access network 120 may provide a band combination list in order of priority indicating one or more network-deployed band combinations to the UE 110. That is, the access network 120 provides the explicit combination list of bands rather than the individual frequency bands to the UE 110.
[0025] FIG. 2 is a diagram depicting an example scenario 200 for early capability request filter provisioning in accordance with implementations of the present disclosure. In scenario 200, a UE is in an RRC idle state and camps on a cell served by a network node. While the UE is in the RRC idle state, the UE receives a system information block, such as a system information block 1 (SIB1) , transmitted as a part of remaining minimum system information (RMSI) , wherein the system information block includes a common capability request filter. After receiving the common capability request filter via the system information, the UE may start early capability construction, including constructing or pre-constructing UE capability information based on the capability request filter. For example, the UE may perform one or more operations, including but not limited to selecting applicable frequency bands, determining candidate band combinations, associating band combinations with corresponding feature sets, and performing fallback or derivation processing. In some implementations, the UE may generate and store at least a portion of the UE capability information while remaining in the RRC idle state. Subsequently, after the UE transits to an RRC connected state, the network node transmits a UECapabilityEnquiry message to the UE. The UECapabilityEnquiry message may include a dedicated capability request filter, which may further request, restrict, or refine the capability information requested by the network node. In response to the UECapabilityEnquiry message, the UE transmits a UECapabilityInformation message to the network node. The UECapabilityInformation message may comprise UE capability information that is at least partially constructed prior to receiving the UECapabilityEnquiry message. As illustrated in FIG. 2, the early provisioning of the capability request filter via system information enables the UE to extend the available processing time for UE capability construction without modifying the timing or procedure of the UE capability reporting defined in existing specifications. This approach reduces UE capability reporting latency and facilitates subsequent network procedures, such as registration procedures and packet data unit (PDU) session establishment.
[0026] FIG. 3 is a diagram depicting another example scenario 300 for early capability request filter provisioning in accordance with implementations of the present disclosure. In scenario 300, a UE is in an RRC idle state and camps on a cell served by a network node. While the UE is in the RRC idle state, the network node transmits to the UE a new system information block, such as a system information block 1bis (SIB1bis) , which is transmitted as a part of RMSI. The SIB1bis is transmitted after the system information block 1 (SIB1) and includes a common capability request filter. After receiving the common capability request filter via the SIB1bis, the UE may start early capability construction. In particular, the UE may pre-construct UE capability information based on the capability request filter by performing one or more operations, including but not limited to, filtering out inapplicable frequency bands, generating candidate band combinations, associating the band combinations with corresponding feature sets, and performing fallback or derivation processing. In some implementations, the UE may generate and store at least a portion of the UE capability information while remaining in the RRC idle state. Subsequently, after the UE transits to an RRC connected state, the network node transmits a UECapabilityEnquiry message to the UE. The UECapabilityEnquiry message may include a dedicated capability request filter to further request, restrict, or refine the capability information requested by the network node. In response to receiving the UECapabilityEnquiry message, the UE transmits a UECapabilityInformation message to the network node. The UECapabilityInformation message may comprise UE capability information that is at least partially constructed prior to receiving the UECapabilityEnquiry message. As illustrated in FIG. 3, by introducing a new system information block (e.g., SIB1bis) transmitted after the SIB1 for provisioning the capability request filter, the UE is enabled to begin constructing UE capability information before entering the RRC connected state. This approach extends the processing time available for UE capability construction without modifying the timing or procedure of UE capability reporting defined in existing specifications, thereby reducing UE capability reporting latency and facilitating subsequent network procedures, such as registration procedures and PDU session establishment.
[0027] FIG. 4 is a diagram depicting another example scenario 400 for early capability request filter provisioning in accordance with implementations of the present disclosure. In scenario 400, a UE initially operates in an RRC idle state and initiates an RRC connection establishment procedure with a network node by transmitting an RRCSetupRequest message. In response, the network node transmits an RRCSetup message to the UE, thereby transiting the UE to an RRC connected state. In scenario 400, the RRCSetup message includes a capability request filter, which is transmitted prior to a UECapabilityEnquiry message. After receiving the capability request filter in the RRCSetup message, the UE may start early capability construction. For example, the UE may begin constructing UE capability information based on the capability request filter by performing one or more operations, including but not limited to, filtering out inapplicable frequency bands, generating candidate band combinations, associating band combinations with corresponding feature sets, and performing fallback or derivation processing. In some implementations, the UE may generate and store at least a portion of the UE capability information while operating in the RRC connected state prior to receiving the UECapabilityEnquiry message. Subsequently, the network node transmits a UECapabilityEnquiry message to the UE. The UECapabilityEnquiry message may include a dedicated capability request filter to further restrict or refine the capability information requested by the network node. In response to receiving the UECapabilityEnquiry message, the UE transmits a UECapabilityInformation message to the network node. The UECapabilityInformation message may comprise UE capability information that is at least partially constructed prior to receiving the UECapabilityEnquiry message. As illustrated in FIG. 4, by provisioning the capability request filter in an earlier RRC downlink message, such as the RRCSetup message, the UE is enabled to start constructing UE capability information at an earlier stage of the RRC connection establishment procedure. This approach provides additional processing time for UE capability construction without altering the existing UE capability reporting procedure or timing defined in current specifications, thereby reducing UE capability reporting latency and facilitating subsequent network procedures, such as registration procedures and PDU session establishment.

[0031] In one aspect, each of processor 512 and processor 522 may be implemented in the form of one or more single-core processors, one or more multi-core processors, or one or more CISC processors. That is, even though a singular term “a processor” is used herein to refer to processor 512 and processor 522, each of processor 512 and processor 522 may include multiple processors in some implementations and a single processor in other implementations in accordance with the present disclosure. In another aspect, each of processor 512 and processor 522 may be implemented in the form of hardware (and, optionally, firmware) with electronic components including, for example and without limitation, one or more transistors, one or more diodes, one or more capacitors, one or more resistors, one or more inductors, one or more memristors and / or one or more varactors that are configured and arranged to achieve specific purposes in accordance with the present disclosure. In other words, in at least some implementations, each of processor 512 and processor 522 is a special-purpose machine specifically designed, arranged and configured to perform specific tasks including capability request filter provisioning in accordance with various implementations of the present disclosure.

Process 600 may be an example implementation of above scenarios / schemes, whether partially or completely, with respect to capability request filter provisioning of the present disclosure. Process 600 may represent an aspect of implementation of features of communication apparatus 510. Process 600 may include one or more operations, actions, or functions as illustrated by one or more of blocks 610 and 620. Although illustrated as discrete blocks, various blocks of process 600 may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Moreover, the blocks of process 600 may be executed in the order shown in FIG. 6 or, alternatively, in a different order. Process 600 may be implemented by communication apparatus 510 or any suitable UE or machine type devices. Solely for illustrative purposes and without limitation, process 600 is described below in the context of communication apparatus 510. Process 600 may begin at block 610.
[0035] At block 610, process 600 may involve processor 512 of communication apparatus 510 receiving, via transceiver 516, a capability request filter information from a network node (e.g., network apparatus 520) prior to a UE capability reporting procedure.

Additional Notes
[0043] 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.
[0044] 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.
[0045] 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. ”
