METHODS AND APPARATUS FOR USER EQUIPMENT CONFIGURATION 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 / 776,354, filed 24 March 2025, the content of which is herein incorporated by reference in its entirety.TECHNICAL FIELD
[0002] The present disclosure is generally related to mobile communications and, more particularly, to user equipment (UE) configuration with respect to an apparatus and a network node 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] Wireless communication systems may be widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may use multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies may include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.
[0005] In communication technologies, a pair of a carrier and a transmission reception point (TRP) may be configured as a serving cell. Each serving cell may be provided with individual layer 1 (L1) configurations. Most L1 parameters are configured individually for the bandwidth parts (BWPs) in a serving cell. Therefore, the user equipment (UE) configuration overhead would be increased. The UE configuration overhead may comprise the configuration for each preconfigured cell group for mobility, the configuration for the serving cells of each cell group for carrier aggregation (CA) , and the BWPs of each serving cell. In addition, when the UE configuration is updated, BWP or CA adaptation, and TRP or cell switching may involve unnecessary, large configuration updates. It may lead to a long interruption time. Although pre-decoding or loading the candidate configuration to be switched to may reduce interrupt time, the UE's memory usage to store the parameters may still be very high.
[0006] Accordingly, how to reduce the UE configuration overhead and the interruption time becomes an important issue for the newly developed wireless communication network. Therefore, there is a need to provide proper schemes for the UE configuration to reduce the UE configuration overhead and the interruption time.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] One objective of the present disclosure is to propose schemes, concepts, designs, systems, methods, and apparatus pertaining to user equipment (UE) configuration with respect to an apparatus and a network node in mobile communications. It is believed that the above-described issue would be avoided or otherwise alleviated by implementing one or more of the proposed schemes described herein.
[0009] In one aspect, a method may involve an apparatus receiving a configuration for one or more candidates from a network node. The candidate may correspond to one or more carriers and one or more transmission reception points (TRPs) . The method may also involve the apparatus performing an operation according to the configuration.
[0010] In another aspect, a method may involve a network node determining a configuration for one or more candidates. The candidate may correspond to one or more carriers and one or more TRPs. The method may also involve the network node transmitting the configuration to a UE.
[0011] It is noteworthy that, although description provided herein may be in the context of certain radio access technologies, networks and network topologies such as 5th Generation System (5GS) and 4G EPS mobile networking, the proposed concepts, schemes and any variation (s) / derivative (s) thereof may be implemented in, for and by other types of wireless and wired communication technologies, networks and network topologies such as, for example and without limitation, Ethernet, Universal Terrestrial Radio Access Network (UTRAN) , E-UTRAN, Global System for Mobile communications (GSM) , General Packet Radio Service (GPRS) / Enhanced Data rates for Global Evolution (EDGE) Radio Access Network (GERAN) , Long-Term Evolution (LTE) , LTE-Advanced, LTE-Advanced Pro, IoT, Industrial IoT (IIoT) , Narrow Band Internet of Things (NB-IoT) , 6th Generation (6G) , and any future-developed networking technologies.

[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 UE configuration 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 a 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 UE configuration 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] According to the implementations of the present disclosure, an apparatus (e.g., UE 110) may receive a configuration for one or more candidates (e.g., the candidate shown in FIG. 2 or candidates shown in FIG. 5) from a network node (e.g., terrestrial network node 125) . Then, the apparatus may perform an operation according to the configuration. The configuration may be received through a radio resource control (RRC) signaling. Each candidate may correspond to one or more carriers (e.g., a carrier bundle) and one or more transmission reception points (TRPs) (e.g., a TRP bundle) . That is, one candidate may be provided with a carrier bundle operating on a TRP bundle. Therefore, according to the implementations of the present disclosure, a fast adaptation in both the frequency domain (e.g., carrier aggregation (CA) or UE-specific BWP adaptation) and the spatial domain (e.g., intra-frequency inter-distributed unit (DU) mobility, intra-frequency intra-distributed unit (DU) mobility, intra-TRP mobility) without increasing UE configuration overhead can be achieved.
[0025] The carrier bundle may comprise one or more carriers within the same frequency band or different frequency bands. The apparatus may use the same downlink (DL) or uplink (UL) synchronization loop and radio frequency (RF) to perform the DL or UL transmission in carriers in the same carrier bundle. In addition, the bundled carrier may share some layer 1 (L1) parameters.
[0026] The TRP bundle may comprise one or more TRPs controlled by the same DU. In an example, if there is only one serving TRP at a time, no requirement may be needed for the TRP bundle. In another example, if there is more than one serving TRP, some requirements may be needed for the multi-TRP operation. The bundled TRP may share the same packet data convergence protocol (PDCP) configuration, radio link control (RLC) configuration, and medium access control (MAC) configuration. In addition, the bundled TRP may share some L1 parameters.
[0027] According to the implementations of the present disclosure, the candidate or the configuration for the candidate may comprise at least one of a candidate index, a common L1 configuration, one or more frequency (or frequency-specific) configurations, and one or more spatial (or spatial-specific) configurations. Multiple frequency configurations and / or spatial configurations may be provided to the apparatus for one candidate. The number of frequency configurations or the number of spatial configurations provided to the apparatus for one candidate may be based on the capability of the apparatus. In addition, the frequency configurations and the spatial configurations may be configured at the same level. For example, the activation or deactivation corresponding to the frequency configurations and the spatial configurations may be performed jointly or individually.
[0028] According to the implementations of the present disclosure, the common L1 configuration may comprise at least one of a measurement configuration (e.g., channel state information-reference signal (CSI-RS) ) , a physical channel common configuration, and a physical signal common configuration. In an implementation, the L1 parameters in the common L1 configuration may not be changed to minimize the interruption time due to the frequency-domain or spatial-domain adaptation. In an implementation, the common L1 configuration may use the same PDCP configuration, RLC configuration, and / or MAC configuration. In an implementation, the common L1 configuration may only involve the operations of the physical (PHY) layer and / or the MAC layer.
[0029] According to the implementations of the present disclosure, the frequency configuration may comprise at least one of an active bandwidth (BW) location and size configuration, a time-domain resource allocation (TDRA) configuration, a frequency-domain resource allocation (FDRA) configuration, a maximum multi-input multi-output (MIMO) layers configuration, and a time division duplex (TDD) for sub-band full duplex (SBFD) .
[0030] According to the implementations of the present disclosure, the spatial configuration comprises at least one of a physical cell identity (PCID) , a time advance (TA) configuration, a reference for time or frequency tracking, a reference for beam management, a reference for pathloss estimation, a DL transmission (TX) power parameter configuration, an UL TX power control scheme configuration (e.g., UL TX power control parameters) , a data or RS scrambling identity, an UL TX scheme, an active antenna port configuration (e.g., active antenna ports) .
[0031] According to the implementations of the present disclosure, the frequency (or frequency-specific) configuration or the spatial (or spatial-specific) configuration may be activated or deactivated according to a network (NW) command (e.g., downlink control information (DCI) or MAC-control element (MAC-CE) ) or a UE-initiated procedure. The apparatus may apply the active frequency configuration or spatial configuration. In an example, more than one spatial configuration (e.g., two or four) may be activated simultaneously (e.g., for multi-TRP operation) . In implementation, the apparatus may maintain the same common L1 configuration in the candidate in an event that a new frequency configuration or the spatial configuration is activated or deactivated in the same candidate.
[0032] FIG. 2 illustrates an example scenario 200 for a configuration for a candidate in accordance with implementations of the present disclosure. Scenario 200 involves an apparatus (e.g., UE) and a network node (e.g., (macro / micro) base station, TRP) of a wireless network (e.g., an LTE network, a 5G / NR network, an IoT network, or a 6G network) . Referring to FIG. 2, the apparatus may receive a configuration for a candidate from the network node. The candidate may correspond to a carrier bundle and a TRP bundle. The carrier bundle may comprise carriers #1~#5. The carriers #1~#3 are within the same frequency band (i.e., band #a) . The carriers #4 and #5 are within the same frequency band (i.e., band #b) . The TRP bundle may comprise four TRPs controlled by the same DU (or share the same DU) . The configuration for the candidate may comprise the common L1 configuration, the frequency (or frequency-specific) configurations #1~#4, and the spatial (or spatial-specific) configurations #1~ #18. Referring to FIG. 2, the frequency (or frequency-specific) configurations #2 and the spatial (or spatial-specific) configurations #6 may be the current serving or active configurations. The frequency (or frequency-specific) configurations #4 and the spatial (or spatial-specific) configurations #12 may be the new serving or active configurations.
[0033] FIG. 3 illustrates an example scenario 300 for L1 parameters for physical downlink shared channel (PDSCH) configuration in accordance with implementations of the present disclosure. Referring to FIG. 3, the L1 parameters for PDSCH configuration may comprise different types of L1 parameters. The L1 parameters DMRS Mapping config, vrb-ToPRB-Interleaver, Aggregation Factor, Rate Matching config, rbg-Size, mcs-Table, prb-BundlingType, and zp-CSI-RS config may be associated with the common L1 configuration. The L1 parameters FDRA, TDRA, maxNrofCodeWordsScheduledByDCI, and maxMIMO-Layers may be associated with the frequency (or frequency-specific) configuration. The L1 parameter dataScramblingIdentity may be associated with the spatial (or spatial-specific) configuration.

[0035] According to the implementations, the network node may configure (or pre-configure) multiple candidates to the apparatus. The candidates controlled by the same DU may be configured for CA operation. The candidates controlled by different DUs may be configured for connected-mode (CONN) mobility. In an implementation, the harmonized configuration and procedure may be applied for the CA operation and the CONN mobility. The harmonized configuration and procedure may comprise at least one of a measurement / reporting, a pre-configuration of a candidate, early DL or UL synchronization, and activation or deactivation of a candidate.
[0036] According to the implementations of the present disclosure, the candidate may be activated or deactivated according to an NW command or a UE-initiated procedure.
[0037] According to the implementations of the present disclosure, the one or more candidates may be associated with at least one of a common configuration for CA and a common configuration for mobility. According to the implementations of the present disclosure, the common configuration for CA may comprise at least one of a higher-layer configuration (e.g., PDCP configuration, RLC configuration, and / or MAC configuration) and an uplink control information (UCI) -related configuration (e.g., scheduling request (SR) , hybrid automatic repeat request (HARQ) -acknowledgement (ACK) , or CSI) .
[0038] According to the implementations of the present disclosure, the common configuration for mobility may comprise at least one of a numerology or subcarrier spacing (SCS) configuration, a common frequency component or unit configuration, a frame structure or TDD configuration (e.g., TDD patterns) , and a measurement configuration for mobility.
[0039] According to the implementations of the present disclosure, the apparatus may maintain the same common configuration for CA or the same common configuration for mobility in an event that a new activated candidate shares the same common configuration for CA or the same common configuration for mobility as a previous activated candidate to minimize the interruption time due to the CA or intra-frequency mobility.
[0040] FIG. 5 illustrates an example scenario 500 for a configuration for multiple candidates in accordance with implementations of the present disclosure. Scenario 500 involves an apparatus (e.g., UE) and a network node (e.g., (macro / micro) base station, TRP) of a wireless network (e.g., an LTE network, a 5G / NR network, an IoT network, or a 6G network) . Referring to FIG. 5, the apparatus may receive a configuration for multiple candidates from the network node. Each candidate may correspond to a carrier bundle and a TRP bundle. The first carrier bundle may comprise carriers #1~#5. The carriers #1~#3 are within the same frequency band (i.e., band #a) . The carriers #4 and #5 are within the same frequency band (i.e., band #b) . The second carrier bundle may comprise carriers #6 and #7. The carriers #6 and #7 are within the same frequency band (i.e., band #c) . The third carrier bundle may comprise carriers #8 and #9. The carriers #8 and #9 are within the same frequency band (i.e., band #d) . The first row of candidates sharing the same carrier bundle (i.e., the first carrier bundle) may share the same common configuration for intra-frequency mobility (i.e., common for intra-frequency inter-DU / central unit (CU) shown in FIG. 5) . The second row of candidates sharing the same carrier bundle (i.e., the second carrier bundle) may share the same common configuration for intra-frequency mobility. The third row of candidates sharing the same carrier bundle (i.e., the third carrier bundle) may share the same common configuration for intra-frequency mobility. The first TRP bundle for the first column of candidates (from left to right) may comprise four TRPs controlled by the same DU (or share the same DU) . The second TRP bundle for the second column of candidates (from left to right) may comprise four TRPs controlled by the same DU (or share the same DU) . The third TRP bundle for the third column of candidates (from left to right) may comprise four TRPs controlled by the same DU (or share the same DU) . The first column of candidates may share the same common configuration for CA (i.e., common for CA shown in FIG. 5) . The second column of candidates may share the same common configuration for CA. The third column of candidates may share the same common configuration for CA. In addition, the apparatus may maintain the same common configuration for CA or the same common configuration for intra-frequency mobility in an event that a new activated candidate shares the same common configuration for CA or the same common configuration for intra-frequency mobility as a previous activated candidate. For example, referring to FIG. 5, in an event that the current serving or active candidate and the new serving or active candidate share the same common configuration for intra-frequency mobility (i.e., common for intra-frequency inter-DU / CU shown in FIG. 5) , the apparatus may maintain the same common configuration for intra-frequency mobility.

[0075] 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.
[0076] 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.
[0077] 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. ”
