WO-2026092587-A1 - METHODS AND APPARATUS OF USER EQUIPMENT CAPABILITY REPORTING IN MOBILE COMMUNICATIONS

Abstract

Various solutions for user equipment (UE) capability reporting in mobile communications are described. The UE may receive a capability enquiry message from a network node. Also, the UE may determine a requested type based on the capability enquiry message. Further, the UE may report a UE capability based on the requested type. By enabling the UE to adaptively report its capability in response to the requested type from the network node, the UE capability reporting process becomes more efficient.

Description

METHODS AND APPARATUS OF USER EQUIPMENT CAPABILITY 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. 63/714,929, filed 1 November 2024, the content of which herein being incorporated by reference in its entirety. TECHNICAL FIELD The present disclosure is generally related to mobile communications and, more particularly, to user equipment capability reporting 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 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 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. An objective of the present disclosure is to propose solutions or schemes that address the aforementioned issues pertaining to user equipment (UE) capability reporting in mobile communications. In one aspect, a method may involve an apparatus receiving a capability enquiry message from a network node. The method may also involve the apparatus determining a requested type based on the capability enquiry message. The method may further involve the apparatus reporting a UE capability based on the requested type. In another aspect, an apparatus may comprise a transceiver which, during operation, wirelessly communicates with a network node of a wireless network. The apparatus may also comprise a processor communicatively coupled to the transceiver. The processor, during operation, may perform operations comprising receiving, via the transceiver, a capability enquiry message from a network node. The processor, during operation, may also perform operations comprising determining a requested type based on the capability enquiry message. The processor, during operation, may further perform operations comprising reporting a UE capability based on the requested type. In yet another aspect, a method may involve a network node transmitting a capability enquiry message corresponding to a requested type to a UE. The method may also involve the network node receiving a UE capability in response to the requested type from the UE. 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 The accompanying drawings are included to provide a further understanding of the disclosure and are incorporated in and constitute a part of the present d
