METHOD AND APPARATUS FOR DEVICE FEATURE SUPPORT AND DEVICE CAPABILITY INDICATION FOR ENHANCED REDUCED CAPABILITY USER EQUIPMENT
[0001] CROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0002] The present disclosure is part of a non-provisional application claiming the priority benefit of U.S. Patent Application No. 63 / 487,897, filed on 2 March 2023, and U.S. Patent Application No. 63 / 466,360, filed 15 May 2023. The contents of aforementioned applications are herein incorporated by reference in their entirety.TECHNICAL FIELD
[0003] The present disclosure is generally related to mobile communications and, more particularly, to device feature support and device capability indication for an enhanced reduced capability (eRedCap) user equipment (UE) .BACKGROUND
[0004] 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.
[0005] A new type of UEs called RedCap UEs (also known as NR-Light UEs) with reduced capability is introduced. Generally, the RedCap UEs are associated with lower communicative capabilities when compared to typical UEs (or called non-RedCap UEs) , such as high-end UEs supporting enhanced mobile broadband (eMBB) and / or ultra-reliable low latency communications (URLLC) services. For example, the RedCap UEs may be limited in terms of maximum bandwidth (e.g., 20 mega-hertz (MHz) in Frequency Range 1 (FR1) , 100 MHz in FR2, etc. ) . The reduced complexity contributes to more cost-efficient NR-Light devices, longer battery life due to lower power consumption, and a smaller device footprint, which enables newer designs for a broad range of use cases, such as industrial sensors, video surveillance, and wearables.
[0006] A further device type (or called eRedCap UEs) with further reduced capability than the legacy RedCap UEs is under study, aiming to further reduce device complexity / cost and power consumption. However, the details of eRedCap UEs have not been fully discussed yet and some issues need to be solved. One of the issues relates to device feature support. Another issue relates to device capability indication. Therefore, there is a need to provide proper schemes to solve these issues.SUMMARY

[0023] 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.

In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations.
[0024] Overview
[0025] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to device feature support and device capability indication for an eRedCap UE. 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.
[0026] FIG. 1 illustrates an example scenario 100 of a communication system supporting eRedCap UEs and non-RedCap UEs in accordance with an implementation of the present disclosure. Scenario 100 involves a communication system including an eRedCap UE 110, a non-RedCap UE 120 and a base station (BS) 130 (e.g., an evolved Node-B (eNB) , a Next Generation Node-B (gNB) , or a transmission / reception point (TRP) and so on) . The eRedCap UE 110 may refer to a wireless communication apparatus associated with lower communicative capabilities (e.g., operated in a 20 MHz channel bandwidth) . For example, the eRedCap UE 110 may be a portable or mobile apparatus, such as an industrial sensor, a video surveillance, or a wearable apparatus (e.g., smartwatch) , or may be an immobile / stationary apparatus, such as an IoT, NB-IoT, or IIoT apparatus (e.g., a smart thermostat, a smart fridge, a smart door lock, a wireless speaker or a home control center) . The non-RedCap UE 120 may refer to a wireless communication apparatus associated with higher communicative capabilities (e.g., operated in a 100 MHz channel bandwidth) . For example, the non-RedCap UE 120 may be a high-end apparatus (e.g., a smartphone, a personal digital assistant, or a computing equipment such as a tablet computer, a laptop computer or a notebook computer) supporting mobile services, such as eMBB, and URLLC services. The BS 130 may belong to part of a radio access network (RAN) of a wireless network (e.g., a 4G / 5G / 6G system) .
[0027] Under a proposed scheme in accordance with the present disclosure, different device features corresponding to different peak-rate reduction type are introduced to indicate the UE capability information for eRedCap UEs (e.g., the eRedCap UE 110) . The first peak-rate reduction type (also referred to as PR1) indicates that the UE operates in a 20MHz channel bandwidth with an additional peak rate reduction by reducing the value VLAYERS x Qm x f, to limit to a peak data rate of approximately 10 megabits per second (Mbps) , where the parameter VLAYERS denotes the maximum supported multiple-input multiple-output (MIMO) layers operated by the UE, the parameter Qm denotes the maximum supported modulation order (e.g., 2 = QPSK, 4 =16QAM, 6 = 64QAM) , and the parameter f denotes the scaling factor with values of 1, 0.8, 0.75, and 0.4 . Specifically, for PR1, the value VLAYERS x Qm x f is 0.75 when VLAYERS=1, or is 0.8 when VLAYERS=2. The second peak-rate reduction type (also referred to as PR3bis) indicates that the UE is limited to operate in a reduced number of physical resource blocks (PRBs) (e.g. 5MHz of PRBs, i.e., the maximum number of (physical downlink / uplink shared channel (PDSCH / PUSCH) PRBs that can be scheduled / configured for unicast and / or broadcast is 25PRBs in 15kilo-hertz (kHz) subcarrier spacing (SCS) or 12PRBs in 30kHz SCS) within its operated 20MHz channel bandwidth, plus additional peak rate reduction to limit to a peak data rate of 10Mbps. Specifically, for PR3bis, the additional peak rate reduction is performed by reducing the value VLAYERS x Qm x f to 3.2, to limit to 10Mbps peak data rate. Accordingly, an eRedCap UE (e.g., the eRedCap UE 110) may provide its UE capability information to the network (e.g., the BS 130) to indicate that it is an eRedCap UE. In an example, an eRedCap UE (PR1 and / or PR3bis) supports additional separate early indication for eRedCap UE in Msg3 for 4-step RACH and / or supports additional separate early indication for eRedCap UE in MsgA PUSCH for 2-step RACH if supported. Additionally, the UE capability information may also indicate that it supports either PR1 (i.e., reduced peak data rate without reduced baseband bandwidth) or PR3bits (i.e., reduced peak data rate with reduced baseband bandwidth) .
[0028] FIG. 2 illustrates an example scenario 200 of bandwidth configurations of different feature supports for eRedCap UEs in accordance with an implementation of the present disclosure. As depicted by the example scenario 200, the bandwidth configuration 210 includes a transport block size scheduled for (PUSCH) transmission (s) and / or (PDSCH) reception (s) based on the feature support for PR1 (e.g., 10Mbps peak data rate without limitation on the number of PRBs) , while the bandwidth configuration 220 includes a reduced / limited PRBs and transport block size scheduled for (PUSCH) transmission (s) and / or (PDSCH) reception (s) based on the feature support for PR3bis (e.g., 10Mbps peak data rate with reduced number of PRBs) . Additionally, or optionally, an eRedCap UE (e.g., the eRedCap UE 110) may be able to signal that it can be (re-) configured to operate as either PR1 or PR3bis by a command from the network. For example, the eRedCap UE may operate as PR1 in a network (node) where the network functionality provides radio access configuration limitations according to PR1, and operate as PR3bis in another network (node) that provides radio access configuration limitations according to PR3bis. That is, the eRedCap UE may support different operation modes (i.e., PR1 or PR3bis) based on the network configurations. In addition, eRedCap UE may support both PR1 and PR3bis modes based on the network configurations.
[0029] In some implementations, the eRedCap UE may provide an indication to the network of its preference to operate in either PR1 or PR3bis operation mode, or to indicate that it would benefit from the opportunity to conserve its battery. The indication may trigger either a reconfiguration or further reconfiguration. Possible reasons for the eRedCap UE indicating its preference for a certain operation mode may include: (1) the type of deployment scenario, such as a terrestrial network or a non-terrestrial / satellite network (e.g. triggering PR3bis operation mode for non-terrestrial / satellite deployment scenario) ; (2) the user commands the UE to operate in a power save mode (e.g. triggering PR3bis operation mode) ; and (3) the type of power supply to the UE changes. Alternatively, the network may initiate the UE reconfiguration to operate in either PR1 or PR3bis operation mode. Possible reasons for selecting either PR1 or PR3bis configuration from the network side may include: (1) the network only supports eRedCap UEs according to one of PR1 or PR3bis and relies on the eRedCap UE using the supported operation mode to ensure interoperability (this may include the scenario where handover is performed between a network supporting only PR1 to a network supporting only PR3bis, or vice versa) ; and (2) in the case of UE reconfiguration to operate in PR3bis operation mode, the network may determine to allow the UE to support power saving, optionally based on the information provided by the UE about its preferred operation mode or desire to conserve its battery.
[0030] Under a proposed scheme in accordance with the present disclosure, an eRedCap UE may provide its UE capability information to the network during and / or after initial access. FIG. 3 illustrates an example scenario 300 of a 2-step RACH procedure with UE capability indication for an eRedCap UE in accordance with an implementation of the present disclosure. Scenario 300 involves an eRedCap UE 310 and a network node 320 (e.g., a BS) which may be part of a wireless network (e.g., an LTE network, a 5G NR network, an IoT network, or a 6G network) . As shown in FIG. 3, at step 302, the eRedCap UE 310 receives system information from the network node 320. The system information may include configurations of radio resources for initial access. More specifically, the configurations for initial access may include configurations of dedicated RACH resource (s) for eRedCap UE. At step 304, the eRedCap UE 310 transmits a random access request (i.e., message-A (MsgA) ) to the network node 320 by using the dedicated RACH resource (s) for eRedCap UEs. The MsgA in a 2-step RACH may comprise a PRACH and a PUSCH. At step 306, the network node 320 replies to the eRedCap UE 310 with a random access response (i.e., message-B (MsgB) ) . As such, use of the dedicated RACH resource (s) for eRedCap UE in MsgA gives an early indication that the initiating UE is an eRedCap UE.An eRedCap early indication based on MsgA (PRACH and / or a PUSCH) for random access can be supported.
[0031] FIG. 4 illustrates an example scenario 400 of a 4-step RACH procedure with UE capability indication for an eRedCap UE in accordance with an implementation of the present disclosure. Scenario 400 involves an eRedCap UE 420 and a network node 430 (e.g., a BS) which may be part of a wireless network (e.g., an LTE network, a 5G NR network, an IoT network, or a 6G network) . As shown in FIG. 4, at step 402, the eRedCap UE 420 receives system information from the network node 430. The system information may include configurations of radio resources for initial access and Logical Channel Identifiers (LCID (s) ) dedicated for eRedCap UE. At step 404, the eRedCap UE 420 transmits a random access request (i.e., message-1 (Msg1) ) to the network node 430 by using the configurations of radio resources for initial access. An early indication for eRedCap UE may be transmitted via Msg1. When Msg1 indication for eRedCap UEs is configured, it is used by eRedCap UEs with or without bandwidth reduction (for PR1 or PR3bis) . In other words, a network-configurable RedCap early indication in Msg1 for eRedCap UE can be supported. At step 406, the network node 430 replies to the eRedCap UE 420 with a random access response (i.e., message-2 (Msg2) ) . Next, at step 408, the eRedCap UE 420 transmits a message of scheduled transmission (i.e., message-3 (Msg3) ) to the network node 430 by using a LCID for eRedCap UE. Msg3 PUSCH based early indication for eRedCap UE may be introduced. LCID can be used for eRedCap early indication in Msg3 PUSCH. At step 410, the network node 430 replies to the eRedCap UE 420 with a message of contention resolution (i.e., message-4 (Msg4) ) . As such, use of the LCID for eRedCap UE in Msg3 gives an early indication that the initiating UE is an eRedCap UE. An eRedCap early indication based on Msg3 (PUSCH) for random access can be supported.
[0032] It is noteworthy that, the initial access procedure (i.e., 2-step RACH or 4-step RACH) for eRedCap UE supporting PR1 is the same as that for eRedCap UE supporting PR3bis. That is, the early indication in MsgA PRACH / MsgA PUSCH / Msg3 PUSCH can only indicate that the initiating UE is an eRedCap UE, but it can not be used to identify whether the UE supports PR1 or PR3bis.
[0033] FIG. 5 illustrates an example scenario 500 of a UE capability transfer procedure for an eRedCap UE in accordance with an implementation of the present disclosure. Scenario 500 involves an eRedCap UE 510 and a network node 520 which may be part of a wireless network (e.g., an LTE network, a 5G NR network, an IoT network, or a 6G network) . As shown in FIG. 5, at step 502, the network node 520 may initiate the UE capability transfer procedure by transmitting a UECapabilityEnquiry message to the eRedCap UE 510. Specifically, the UE capability transfer procedure may be initiated when the eRedCap UE 510 is in the RRC_CONNECTED state and when the network node 520 needs (additional) UE radio access capability information. At step 504, the eRedCap UE 510 may transmit a UECapabilityInformation message to the network node 520. Specifically, the UECapabilityInformation message may contain UE capability information indicating that the eRedCap UE 510 supports reduced peak data rate with or without reduced baseband bandwidth (i.e., the UE capability information indicates whether the eRedCap UE 510 supports PR1 or PR3bis) . For example, the UE capability information may be signaled in one or more information elements (IEs) , including supportOfERedCap-r18 and eRedCapNotReducedBB-BW-r18. The IE supportOfERedCap-r18 indicates that the UE is an eRedCap UE with reduced peak data rate and reduced baseband bandwidth in FR1, while the IE eRedCapNotReducedBB-BW-r18 indicates that the UE is an eRedCap UE without reduced baseband bandwidth in FR1. Particularly, a UE supporting eRedCapNotReducedBB-BW-r18 should also indicate the support of supportOfERedCap-r18. In other words, the features of PR1 are indicated by both the IEs supportOfERedCap-r18 and eRedCapNotReducedBB-BW-r18, while the features of PR3bis are indicated by only the IE supportOfERedCap-r18.

[0041] Each of communication apparatus 610 and network apparatus 620 may be a communication entity capable of communicating with each other using various proposed schemes in accordance with the present disclosure. For illustrative purposes and without limitation, a description of capabilities of communication apparatus 610, as a UE, and network apparatus 620, as a network node (e.g., BS) , is provided below.
[0042] Under certain proposed schemes in accordance with the present disclosure with respect to device feature support and device capability indication for an eRedCap UE, processor 612 of communication apparatus 610 may transmit, via transceiver 616, first UE capability information to network apparatus 620. Specifically, the first UE capability information (e.g., an early indication in RACH) may indicate that communication apparatus 610 is an eRedCap UE supporting a reduced peak data rate. Then, processor 612 may receive, via transceiver 616, a first configuration configuring one or more transmissions or receptions from network apparatus 620. Specifically, the first configuration may be based on the reduced peak data rate. Also, processor 612 may perform, via transceiver 616, the one or more transmissions or receptions according to the first configuration. Correspondingly, processor 622 of network apparatus 620 may receive, via transceiver 626, the first UE capability information from communication apparatus 610. Then, processor 622 may transmit, via transceiver 626, a first configuration configuring one or more transmissions or receptions to communication apparatus 610. Also, processor 622 may perform, via transceiver 626, the one or more transmissions or receptions according to the first configuration.
[0043] In some implementations, processor 612 may also transmit, via transceiver 616, second UE capability information to network apparatus 620, wherein the second UE capability information (e.g., UE capability reporting in connected mode) indicates that communication apparatus 610 is the eRedCap UE supporting the reduced peak data rate with or without a reduced baseband bandwidth.
[0044] In some implementations, the one or more transmissions or receptions may be further based on a maximum number of PRBs.
[0045] In some implementations, the maximum number of PRBs may include 25 PRBs for 15 kHz SCS or 12 PRBs for 30 kHz SCS.
[0046] In some implementations, the reduced peak data rate may be approximately 10 Mbps. For example, depending on the combination of UL / DL and SCSs (15kHz or 30kHz) , the obtained data rate may range from 10. x Mbps to 12. x Mbps.
[0047] In some implementations, in a case that communication apparatus 610 is the eRedCap UE supporting the reduced peak data rate without the reduced baseband bandwidth, a product of a maximum number of MIMO layers, a maximum modulation order, and a scaling factor corresponding to the reduced peak data rate may be 0.75 when the maximum number of MIMO layers is 1, or may be 0.8 when the maximum number of MIMO layers is 2.
[0048] In some implementations, in a case that communication apparatus 610 is the eRedCap UE supporting the reduced peak data rate with the reduced baseband bandwidth, a product of a maximum number of MIMO layers, a maximum modulation order, and a scaling factor corresponding to the reduced peak data rate may be 3.2.
[0049] In some implementations, the first UE capability information may include an early indication for the eRedCap UE in a Msg3 or Msg1 during a 4-step RACH procedure, or an early indication for the eRedCap UE in a MsgA during a 2-step RACH procedure.

[0071] Additional Notes
[0072] 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.
[0073] 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.
[0074] 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. ”
