AI Technical Summary
The current 3GPP specification's full configuration (fullConfig) in RRC reconfiguration messages causes delays and potential data loss during handovers due to the release and addition of data radio bearers, which can be severe for real-time services like voice calls, as unacknowledged PDCP packets may not be retransmitted in time or sequence.
A method involving a UE receiving a reconfiguration message that excludes releasing the radio bearer configuration and PDCP/SDAP configuration, maintaining DRBs with these configurations, and using a new flag to apply full configuration only to non-radio bearer configurations, allowing delta configuration for other changes.
This approach reduces delays and data loss by maintaining essential configurations, ensuring timely retransmission of packets and minimizing service disruptions, particularly beneficial for real-time communications.

Abstract
Description
FULL CONFIGURATION OF NON-RADIO BEARER CONFIGURATION IN MOBILE COMMUNICATIONSCROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0001] The present disclosure claims the priority benefit of U.S. Patent Application No. 63 / 691, 407, filed 06 September 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 full configuration of non-radio bearer configuration in mobile communications.BACKGROUND
[0003] In wireless communications such as mobile communications under the current 3rd Generation Partnership Project (3GPP) specification, full configuration (fullConfig) can be sent in a radio resource control (RRC) reconfiguration message. When a user equipment (UE) receives fullConfig, the UE releases all existing configuration (s) and uses the configuration in the RRC reconfiguration message as a fresh new configuration. Thus, fullConfig can be used by radio access network (RAN) nodes to avoid comparing old configuration (s) with a new configuration (e.g., during handover) and determining a delta configuration. For data radio bearer (DRB) configuration, fullConfig requires releasing of existing DRBs / service data adaptation protocols (SDAPs) and adding new DRBs / SDAPs as per 3GPP technical specification (TS) 38.331 5.3.5.11.
[0004] Regarding the configuration structure of a radio bearer configuration and packet data convergence protocol (PDCP) configuration (PDCP-Config) , radio link control (RLC) configuration (RLC-Config) , medium access control (MAC) configuration, a radio bearer configuration (radioBearerConfig) defines a DRB list and associated PDCP-Config and SDAP-Config. Additionally, RLC-Config is under rlc-BearerToAddModList, which is separate from radioBearerConfig. Moreover, MAC configuration is under mac-CellGroupConfig, which is separate from radioBearerConfig. As such, under current 3GPP specifications, fullConfig may cause the UE to release and add DRBs. When the UE releases and adds DRBs, delay may be added in handover to cause potential data loss due to unacknowledged PDCP packets to return to an upper layer which may not retransmit in time or in sequence. For voice calls or real-time services, this issue can become more severe because data can be aged out. Therefore, there is a need for a solution of full configuration of non-radio bearer configuration in mobile communications.SUMMARY
[0005] 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.
[0006] An objective of the present disclosure is to propose solutions or schemes that address the issue (s) described herein. More specifically, various schemes proposed in the present disclosure are believed to provide solutions pertaining to full configuration of non-radio bearer configuration in mobile communications. It is believed that implementations of one or more of the schemes proposed herein may address or otherwise alleviate the issues described above.
[0007] In one aspect, a method may involve a UE receiving a reconfiguration message from a network. In response to receiving the reconfiguration message, the method may involve the UE: (a) releasing an old configuration except a radio bearer configuration and a PDCP / SDAP configuration; and (b) maintaining DRBs with the PDCP / SDAP configuration. The reconfiguration message includes an indication to release the old configuration excluding the radio bearer configuration and the PDCP / SDAP configuration.
[0008] In another aspect, a method may involve a network node of a network transmitting a reconfiguration message to a UE to cause the UE to perform operations including: (a) releasing an old configuration except a radio bearer configuration and a PDCP / SDAP configuration; and (b) maintaining DRBs with the PDCP configuration / SDAP configuration. The method may also involve the network node receiving a reconfiguration complete message from the UE.

[0018] 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
[0019] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to full configuration of non-radio bearer configuration 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.
[0020] FIG. 1 illustrates an example network environment 100 in which various solutions and schemes in accordance with the present disclosure may be implemented. FIG. 2 ~ FIG. 7 illustrate examples of implementation of various proposed schemes in network environment 100 in accordance with the present disclosure. The following description of various proposed schemes is provided with reference to FIG. 1 ~ FIG. 7.
[0021] Referring to FIG. 1, network environment 100 involves a UE 110 (in wireless communication with a wireless network 120 (e.g., a 6G mobile network including a non-terrestrial network (NTN) and a terrestrial network (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 an NTN serving cell for wireless communication with UE 110. In some implementations, UE 110 may be a smartphone, a wearable device, 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, UE 110, network 120, terrestrial network node 125, and non-terrestrial network node 128 may implement various schemes pertaining to full configuration of non-radio bearer configuration in accordance with the present disclosure, as described below.
[0022] 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. Moreover, as used herein, a lower layer may refer to a layer in the 5GMM protocol stack that is lower than the radio RRC layer, such as a PDCP layer, a RLC layer, a MAC layer, a physical (PHY) layer, or so forth.
[0023] FIG. 2 illustrates an example design 200 under a proposed scheme in accordance with the present disclosure. Under the proposed scheme, a new full configuration flag may be added to apply full configuration only to non-RadioBearerConfig (and non-PDCP) configuration (s) , herein referred to as “fullConfigNonRadioBearerConfig” . When this new flag is used, DRBs may be maintained with PDCP reestablishment (e.g., not to release and add DRB) . Moreover, when this new flag is used, a UE (e.g., UE 110) and a network (e.g., wireless network 120) may use delta configuration to change some of the old configuration in the RadioBearerConfig information element (IE) (and PDCP and SDAP configuration of this IE) . For instance, the delta configuration may apply to one IE with “Need M” condition, with “Need M” meaning that, only when there is change, there is a need to include the new value of the information element (IE) to indicate the new configuration. Otherwise, if there is nothing included in the reconfiguration, the old configuration may continue to be used as “Need M” implies to maintain the old configuration. Under the proposed scheme, when reconfiguration includes fullConfig which releases all old configuration (s) , this new flag of fullConfigNonRadioBearerConfig may not be included as fullConfig requires the UE to release its old configuration including the radioBearerConfig.
[0024] FIG. 3 illustrates an example design 300 under a proposed scheme in accordance with the present disclosure. Design 300 may pertain to at least a portion of the content of a fullConfigNonRadioBearerConfig, which may be utilized to release all old configuration (s) except radioBearerConfig (and thus PDCP / SDAP configuration) .
[0025] FIG. 4 illustrates an example design 400 under a proposed scheme in accordance with the present disclosure. Design 400 may pertain to at least a portion of the content of a RRC reconfiguration message.
[0026] In view of the above, under the various proposed schemes in accordance with the present disclosure, a method of releasing old configuration, excluding radio bearer configuration and PDCP / SDAP configuration, in a wireless communication network (e.g., network 120) may involve a UE (e.g., UE 110) receiving, from a network node (e.g., terrestrial network node 125 or non-terrestrial network node 128) a reconfiguration message with an indication to release an old configuration excluding a radio bearer configuration and PDCP / SDAP configuration. The method may also involve the UE releasing the old configuration except the radio bearer configuration and PDCP / SDAP configuration in response to receiving the reconfiguration message. The method may additionally involve the UE maintaining DRBs with the PDCP / SDAP configuration. The method may further involve the UE replying to the network node with a reconfiguration complete message, as shown in FIG. 2. Illustrative Implementations

[0047] 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.
[0048] 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.
[0049] 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. ”
