Abstract
Description
Technical Field
[0001] The present disclosure relates to conflict resolution in wireless communications. Background Art
[0002] The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) is a technology that allows high-speed packet communications. Many solutions have been proposed for the LTE goal, including those aimed at reducing user and supplier costs, improving service quality, and expanding and improving coverage and system capacity. As upper layer requirements, 3GPP LTE requires reduced cost per bit, increased service availability, flexible use of frequency bands, simple structure, open interfaces, and appropriate power consumption of terminals.
[0003] The International Telecommunication Union (ITU) and 3GPP have begun work on developing requirements and specifications for New Radio (NR) systems. 3GPP must identify and develop the technical components required for successful standardization of new RATs that will meet both urgent market needs and longer-term requirements set forth by the ITU Radiocommunication Sector (ITU-R) International Mobile Telecommunications (IMT)-2020 process in a timely manner. In addition, NR should be able to use any spectrum band up to at least the 100 GHz range that can be used for wireless communications even in the more distant future.
[0004] The goal of NR is to be a single technology framework that addresses all use cases, requirements and deployment scenarios, including enhanced mobile broadband (eMBB), massive machine type communications (mMTC), ultra-reliable and low latency communications (URLLC), etc. NR should be inherently forward compatible.
[0005] In wireless communication, a user equipment (UE) may use radio resources (e.g., a first radio resource and a second radio resource) to perform an operation. However, there may be a situation where the capabilities of the UE do not support simultaneous execution of an operation on the first radio resource and an operation on the second radio resource. This may be referred to as a capability conflict between the first radio resource and the second radio resource, and / or a conflict between the first radio resource and the second radio resource. The conflict may occur in various situations, such as in multiple networks associated with a multi-universal subscriber identity module (MUSIM) operation. Summary of the invention

[0039] Figure 1 An example of a communication system to which an implementation of the present disclosure is applied is shown.
[0040] Figure 1 The 5G usage scenarios shown are only exemplary, and the technical features of the present disclosure can be applied to Figure 1 Other 5G usage scenarios not shown.
[0041] The three main demand categories for 5G include: (1) enhanced mobile broadband (eMBB) category, (2) massive machine type communication (mMTC) category, and (3) ultra-reliable and low-latency communication (URLLC) category.
[0042] refer to Figure 1, the communication system 1 includes wireless devices 100a to 100f, a base station (BS) 200, and a network 300. Figure 1 A 5G network is illustrated as an example of a network of the communication system 1, but implementations of the present disclosure are not limited to the 5G system and may be applied to future communication systems other than the 5G system.
[0043] BS 200 and network 300 may be implemented as wireless devices, and a specific wireless device may operate as a BS / network node relative to other wireless devices.
[0044] The wireless devices 100a to 100f represent devices that perform communication using a radio access technology (RAT) (e.g., 5G NR or LTE) and may be referred to as communication / radio / 5G devices. The wireless devices 100a to 100f may include, but are not limited to, a robot 100a, a vehicle 100b-1 and 100b-2, an extended reality (XR) device 100c, a handheld device 100d, a home appliance 100e, an Internet of Things (IoT) device 100f, and an artificial intelligence (AI) device / server 400. For example, a vehicle may include a vehicle with a wireless communication function, an autonomous vehicle, and a vehicle capable of performing communication between vehicles. A vehicle may include an unmanned aerial vehicle (UAV) (e.g., a drone). The XR device may include an augmented reality (AR) / virtual reality (VR) / mixed reality (MR) device and may be implemented in the form of a head-mounted device (HMD), a head-up display (HUD) installed in a vehicle, a television, a smart phone, a computer, a wearable device, a home appliance device, a digital signage, a vehicle, a robot, and the like. Handheld devices may include smart phones, smart tablets, wearable devices (e.g., smart watches or smart glasses), and computers (e.g., notebooks). Home appliances may include TVs, refrigerators, and washing machines. IoT devices may include sensors and smart meters.
[0045] In the present disclosure, the wireless devices 100a to 100f may be referred to as user equipment (UE). UE may include, for example, a cellular phone, a smart phone, a laptop computer, a digital broadcast terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a navigation system, a plate-shaped personal computer (PC), a tablet PC, an ultrabook, a vehicle, a vehicle with an autonomous driving function, a connected car, a UAV, an AI module, a robot, an AR device, a VR device, an MR device, a hologram device, a public safety device, an MTC device, an IoT device, a medical device, a FinTech device (or a financial device), a security device, a weather / environmental device, a device related to 5G services, or a device related to the field of the fourth industrial revolution.
[0046] The wireless devices 100a to 100f may be connected to the network 300 via the BS 200. The AI technology may be applied to the wireless devices 100a to 100f, and the wireless devices 100a to 100f may be connected to the AI server 400 via the network 300. The network 300 may be configured using a 3G network, a 4G (e.g., LTE) network, a 5G (e.g., NR) network, and a super 5G network. Although the wireless devices 100a to 100f may communicate with each other via the BS 200 / network 300, the wireless devices 100a to 100f may perform direct communication (e.g., side link communication) with each other without passing through the BS 200 / network 300. For example, the vehicles 100b-1 and 100b-2 may perform direct communication (e.g., vehicle-to-vehicle (V2V) / vehicle-to-everything (V2X) communication). An IoT device (e.g., a sensor) may perform direct communication with other IoT devices (e.g., a sensor) or other wireless devices 100a to 100f.
[0047] Wireless communication / connection 150a, 150b, and 150c may be established between wireless devices 100a to 100f and / or between wireless devices 100a to 100f and BS200 and / or between BS200. Here, wireless communication / connection may be established through various RATs (e.g., 5G NR) such as uplink / downlink communication 150a, sidelink communication (or device-to-device (D2D) communication) 150b, inter-base station communication 150c (e.g., relay, integrated access and backhaul (IAB)), etc. The wireless devices 100a to 100f and BS200 / wireless devices 100a to 100f may send / receive radio signals to / from each other through wireless communication / connection 150a, 150b, and 150c. For example, wireless communication / connection 150a, 150b, and 150c may send / receive signals through various physical channels. To this end, various configuration information configuration processes for sending / receiving radio signals, various signal processing processes (e.g., channel coding / decoding, modulation / demodulation, and resource mapping / demapping), and at least a portion of the resource allocation process can be performed based on various proposals of the present disclosure.
[0048] NR supports multiple numerologies (and / or multiple subcarrier spacings (SCS)) to support various 5G services. For example, if the SCS is 15kHz, wide areas can be supported in traditional cellular bands, while if the SCS is 30kHz / 60kHz, dense cities, lower latency, and wider carrier bandwidths can be supported. If the SCS is 60kHz or higher, bandwidths greater than 24.25GHz can be supported to overcome phase noise.
[0049] The NR frequency band may be defined as two types of frequency ranges, namely, frequency range 1 (FR1) and frequency range 2 (FR2). The numerical values of the frequency ranges may be changed. For example, the two types of frequency ranges (FR1 and FR2) may be as shown in Table 1 below. For ease of explanation, in the frequency range used in the NR system, FR1 may mean "a range below 6 GHz", FR2 may mean "a range above 6 GHz", and may be referred to as millimeter wave (mmW).
[0050] [Table 1]
[0051] Frequency range name Corresponding frequency range Subcarrier spacing FR1 450MHz-6000MHz 15, 30, 60kHz FR2 24250MH-52600MHz 60, 120, 240kHz
[0052] As described above, the numerical value of the frequency range of the NR system can be changed. For example, FR1 may include a frequency band of 410 MHz to 7125 MHz as shown in Table 2 below. That is, FR1 may include a frequency band of 6 GHz (or 5850 MHz, 5900 MHz, 5925 MHz, etc.) or higher. For example, a frequency band of 6 GHz (or 5850 MHz, 5900 MHz, 5925 MHz, etc.) or more included in FR1 may include an unlicensed frequency band. The unlicensed frequency band may be used for various purposes, for example, for communication of vehicles (e.g., autonomous driving).
[0053] [Table 2]
[0054] Frequency range name Corresponding frequency range Subcarrier spacing FR1 410MHz-7125MHz 15, 30, 60kHz FR2 24250MHz-52600MHz 60, 120, 240kHz
[0055] Here, the radio communication technology implemented in the wireless device in the present disclosure may include narrowband Internet of Things (NB-IoT) technology for low power communication and LTE, NR and 6G. For example, NB-IoT technology may be an example of low power wide area network (LPWAN) technology, which may be implemented in specifications such as LTE Cat NB1 and / or LTE Cat NB2, and may not be limited to the above names. Additionally and / or alternatively, the radio communication technology implemented in the wireless device in the present disclosure may communicate based on LTE-M technology. For example, LTE-M technology may be an example of LPWAN technology, and may be called by various names such as enhanced machine type communication (eMTC). For example, LTE-M technology may be implemented in at least one of various specifications, such as 1) LTE Cat 0, 2) LTE Cat M1, 3) LTE Cat M2, 4) LTE non-bandwidth limited (non-BL), 5) LTE-MTC, 6) LTE machine type communication and / or 7) LTE M, and may not be limited to the above names.

[0086] Figure 4 and Figure 5 An example of a protocol stack in a 3GPP-based wireless communication system to which an implementation of the present disclosure is applied is shown.
[0087] Specifically, Figure 4 An example of a radio interface user plane protocol stack between a UE and a BS is illustrated, and Figure 5An example of a radio interface control plane protocol stack between a UE and a BS is illustrated. The control plane refers to a path for transmitting control messages used to manage calls by the UE and the network. The user plane refers to a path for transmitting data generated in the application layer (for example, voice data or Internet packet data). Figure 4 , the user plane protocol stack can be divided into layer 1 (ie, PHY layer) and layer 2. Figure 5 , the control plane protocol stack can be divided into layer 1 (ie, PHY layer), layer 2, layer 3 (eg, RRC layer), and non-access stratum (NAS) layer. Layer 1, layer 2, and layer 3 are called access stratum (AS).
[0088] In the 3GPP LTE system, Layer 2 is separated into the following sublayers: MAC, RLC, and PDCP. In the 3GPP NR system, Layer 2 is separated into the following sublayers: MAC, RLC, PDCP, and SDAP. The PHY layer provides transport channels to the MAC sublayer, the MAC sublayer provides logical channels to the RLC sublayer, the RLC sublayer provides RLC channels to the PDCP sublayer, and the PDCP sublayer provides radio bearers to the SDAP sublayer. The SDAP sublayer provides Quality of Service (QoS) flows to the 5G core network.
[0089] In the 3GPP NR system, the main services and functions of the MAC sublayer include: mapping between logical channels and transport channels; multiplexing MAC SDUs belonging to one or different logical channels to / demultiplexing transport blocks (TBs) delivered to / from the physical layer on the transport channel; scheduling information reporting; error correction through hybrid automatic repeat request (HARQ) (one HARQ entity per cell in the case of carrier aggregation (CA); priority handling between UEs with dynamic scheduling; priority handling between logical channels of one UE with logical channel prioritization; padding. A single MAC entity can support multiple parameter sets, transmission timings, and cells. Mapping restrictions in logical channel prioritization control which parameter set(s), cell, and transmission timing a logical channel can use.
[0090] MAC provides different kinds of data transmission services. In order to adapt to different kinds of data transmission services, multiple types of logical channels are defined, that is, each logical channel supports the transmission of a specific type of information. Each logical channel type is defined by what type of information is transmitted. Logical channels are divided into two groups: control channels and traffic channels. Control channels are only used for the transmission of control plane information, and traffic channels are only used for the transmission of user plane information. The broadcast control channel (BCCH) is a downlink logical channel for broadcasting system control information, the paging control channel (PCCH) is a downlink logical channel for transmitting paging information, system information change notifications, and indications of ongoing public warning services (PWS) broadcasts, the common control channel (CCCH) is a logical channel for sending control information between the UE and the network and for UEs that do not have an RRC connection with the network, and the dedicated control channel (DCCH) is a point-to-point bidirectional logical channel that sends dedicated control information between the UE and the network and is used by UEs with an RRC connection. The dedicated traffic channel (DTCH) is a point-to-point logical channel dedicated to one UE, which is used to transmit user information. DTCH can exist in both the uplink and downlink. In the downlink, there are the following connections between logical channels and transport channels: BCCH can be mapped to the broadcast channel (BCH); BCCH can be mapped to the downlink shared channel (DL-SCH); PCCH can be mapped to the paging channel (PCH); CCCH can be mapped to DL-SCH; DCCH can be mapped to DL-SCH; and DTCH can be mapped to DL-SCH. In the uplink, there are the following connections between logical channels and transport channels: CCCH can be mapped to the uplink shared channel (UL-SCH); DCCH can be mapped to UL-SCH; and DTCH can be mapped to UL-SCH.
[0091] The RLC sublayer supports three transmission modes: transparent mode (TM), unacknowledged mode (UM) and acknowledged mode (AM). RLC configuration is for each logical channel and does not depend on parameter sets and / or transmission duration. In 3GPP NR systems, the main services and functions of the RLC sublayer depend on the transmission mode and include: delivery of upper layer PDUs; sequence numbering independent of one of PDCP (UM and AM); error correction through ARQ (AM only); segmentation (AM and UM) and re-segmentation (AM only) of RLC SDUs; reassembly of SDUs (AM and UM); duplicate detection (AM only); RLC SDU discard (AM and UM); RLC re-establishment; protocol error detection (AM only).
[0092] In the 3GPP NR system, the main services and functions of the PDCP sublayer for the user plane include: sequence numbering; header compression and decompression using robust header compression (ROHC); transmission of user data; reordering and duplicate detection; in-sequence delivery; PDCP PDU routing (in the case of split bearers); retransmission of PDCP SDU; ciphering, deciphering and integrity protection; PDCP SDU discard; PDCP re-establishment and data recovery for RLC AM; PDCP status report for RLC AM; PDCP PDU duplication and duplicate discard indication to lower layers. The main services and functions of the PDCP sublayer for the control plane include: sequence numbering; ciphering, deciphering and integrity protection; transmission of control plane data; reordering and duplicate detection; in-sequence delivery; PDCP PDU duplication and duplicate discard indication to lower layers.
[0093] In 3GPP NR system, the main services and functions of SDAP include: mapping between QoS flows and data radio bearers; marking QoS flow ID (QFI) in both DL and UL packets. A single SDAP protocol entity is configured for each individual PDU session.
[0094] In the 3GPP NR system, the main services and functions of the RRC sublayer include: broadcast of system information related to AS and NAS; paging initiated by 5GC or NG-RAN; establishment, maintenance and release of RRC connection between UE and NG-RAN; security functions including key management; establishment, configuration, maintenance and release of signaling radio bearers (SRBs) and data radio bearers (DRBs); mobility functions (including: handover and context transfer; UE cell selection and reselection and control of cell selection and reselection; inter-RAT mobility); QoS management functions; UE measurement reporting and control of reporting; detection and repair of radio link failures; transmission of NAS messages from UE to NAS / from NAS to UE.
[0095] Figure 6 The frame structure in a 3GPP-based wireless communication system to which the implementation of the present disclosure is applied is shown.
[0096] Figure 6The frame structure shown is only exemplary, and the number of subframes, the number of time slots, and / or the number of symbols in a frame may vary. In a 3GPP-based wireless communication system, OFDM parameter sets (e.g., subcarrier spacing (SCS), transmission time interval (TTI) duration) may be configured differently between multiple cells aggregated for one UE. For example, if the UE is configured with different SCSs for cells aggregated for the cells, the (absolute time) duration of time resources (e.g., subframes, time slots, or TTIs) including the same number of symbols may be different among the aggregated cells. In this article, the symbol may include an OFDM symbol (or CP-OFDM symbol), an SC-FDMA symbol (or a discrete Fourier transform-spread-OFDM (DFT-s-OFDM) symbol).
[0097] refer to Figure 6 , downlink and uplink transmissions are organized into frames. Each frame has T f =10ms duration. Each frame is divided into two half-frames, where each half-frame has a duration of 5ms. Each half-frame includes 5 sub-frames, where the duration of each sub-frame is T sf is 1 ms. Each subframe is divided into slots, and the number of slots in a subframe depends on the subcarrier spacing. Each slot includes 14 or 12 OFDM symbols based on a cyclic prefix (CP). In a normal CP, each slot includes 14 OFDM symbols, and in an extended CP, each slot includes 12 OFDM symbols. The parameter set is based on an exponentially scalable subcarrier spacing βf=2 u *15kHz.
[0098] Table 3 shows the subcarrier spacing βf=2 u *N is the number of OFDM symbols per slot for normal CP of 15kHz slot symb , the number of time slots per frame N frame,u slot And the number of time slots N in each subframe subframe,u slot .
[0099] [Table 3]
[0100] u <![CDATA[N slot symb ]]> <![CDATA[N frame,u slot ]]> <![CDATA[N subframe,u slot ]]> 0 14 10 1 1 14 20 2 2 14 40 4 3 14 80 8 4 14 160 16
[0101] Table 4 shows the subcarrier spacing βf=2 u *N number of OFDM symbols per slot for extended CP of 15kHz slot symb , the number of time slots per frame N frame,u slot And the number of time slots N in each subframesubframe,u slot .
[0102] [Table 4]
[0103] u <![CDATA[N slot symb ]]> <![CDATA[N frame,u slot ]]> <![CDATA[N subframe,u slot ]]> 2 12 40 4
[0104] A slot includes a plurality of symbols (eg, 14 or 12 symbols) in the time domain. For each parameter set (eg, subcarrier spacing) and carrier, a common resource block (CRB) N indicated by higher layer signaling (eg, RRC signaling) is allocated. start,u grid To begin, we define N size,u grid,x *N RB sc subcarriers and N subframe,u symb OFDM symbol resource grid, where N size,u grid,x N is the number of resource blocks (RBs) in the resource grid, and the subscript x is DL for the downlink and UL for the uplink. RB sc is the number of subcarriers per RB. In 3GPP-based wireless communication systems, N RB sc Typically 12. There is one resource grid for a given antenna port p, subcarrier spacing configuration u, and transmission direction (DL or UL). The carrier bandwidth N for subcarrier spacing configuration u size,u grid Given by high-level parameters (e.g., RRC parameters). Each element in the resource grid for antenna port p and subcarrier spacing configuration u is called a resource element (RE), and one complex symbol can be mapped to each RE. Each RE in the resource grid is uniquely identified by an index k in the frequency domain and an index l representing the symbol position in the time domain relative to a reference point. In a 3GPP-based wireless communication system, an RB is defined by 12 consecutive subcarriers in the frequency domain. In a 3GPPNR system, RBs are classified into CRBs and physical resource blocks (PRBs). CRBs are numbered upward from 0 in the frequency domain for subcarrier spacing configuration u. The center of subcarrier 0 of CRB 0 for subcarrier spacing configuration u coincides with "point A" used as a common reference point for the resource block grid. In a 3GPP NR system, PRBs are defined within a bandwidth part (BWP) and are numbered from 0 to N. size BWP,i -1 numbering, where i is the number of the bandwidth part. Physical resource block n in bandwidth part i PRB With common resource block n CRB The relationship between them is as follows: PRB =n CRB +Nsize BWP,i , where N size BWP,i It is a common resource block where the bandwidth part starts relative to CRB0. A BWP includes multiple consecutive resource blocks. A carrier can include up to N (e.g., 5) BWPs. A UE can be configured with one or more BWPs on a given component carrier. Only one BWP can be activated at a time among the BWPs configured for a UE. The active BWP defines the operating bandwidth of the UE within the operating bandwidth of the cell.
[0105] In the present disclosure, the term "cell" may refer to a geographical area where one or more nodes provide a communication system or to a radio resource. A "cell" as a geographical area may be understood as a coverage area in which a node can provide services using a carrier, and a "cell" as a radio resource (e.g., a time-frequency resource) is associated with a bandwidth as a frequency range configured by a carrier. A "cell" associated with a radio resource is defined by a combination of downlink resources and uplink resources (e.g., a combination of a DL component carrier (CC) and a ULCC). A cell may be configured only by downlink resources, or may be configured by downlink resources and uplink resources. Since the DL coverage (which is the range in which a node can send a valid signal) and the UL coverage (which is the range in which a node can receive a valid signal from a UE) depend on the carrier carrying the signal, the coverage of a node may be associated with the coverage of a "cell" of a radio resource used by the node. Therefore, the term "cell" may sometimes be used to represent the service coverage of a node, to represent a radio resource at other times, or to represent a range in which a signal using a radio resource can reach with effective strength at other times.
[0106] In CA, two or more CCs are aggregated. The UE can receive or transmit on one or more CCs simultaneously according to its capabilities. CA is supported for both continuous CCs and non-contiguous CCs. When CA is configured, the UE has only one RRC connection with the network. When the RRC connection is established / reestablished / switched, one serving cell provides NAS mobility information, and when the RRC connection is reestablished / switched, one serving cell provides security input. This cell is called the primary cell (PCell). The PCell is a cell operating on the primary frequency, where the UE performs an initial connection establishment process or initiates a connection reestablishment process. Depending on the UE capabilities, the secondary cell (SCell) can be configured to form a set of serving cells together with the PCell. The SCell is a cell that provides additional radio resources on top of a special cell (SpCell). Therefore, the set of configured serving cells for the UE always consists of one PCell and one or more SCells. For dual connection (DC) operation, the term SpCell refers to the PCell of the primary cell group (MCG) or the primary SCell (PSCell) of the secondary cell group (SCG). SpCell supports PUCCH transmission and contention-based random access and is always activated. MCG is a group of serving cells associated with a master node, which includes SpCell (PCell) and optionally one or more SCells. For UEs configured with DC, SCG is a subset of serving cells associated with a secondary node, which includes PSCell and zero or more SCells. For UEs in RRC_CONNECTED that are not configured with CA / DC, there is only one serving cell consisting of PCell. For UEs in RRC_CONNECTED that are configured with CA / DC, the term "serving cell" is used to refer to a set of cells consisting of SpCell and all SCells. In DC, two MAC entities are configured in the UE: one for MCG and one for SCG.
[0107] Figure 7 An example of data flow in a 3GPP NR system to which an implementation of the present disclosure is applied is shown.
[0108] refer to Figure 7 , "RB" means radio bearer, and "H" means header. Radio bearers are classified into two groups: DRB for user plane data and SRB for control plane data. MAC PDU is transmitted / received to / from an external device through the PHY layer using radio resources. MAC PDU arrives at the PHY layer in the form of a transport block.
[0109] In the PHY layer, uplink transport channels UL-SCH and RACH are mapped to their physical channels, physical uplink shared channel (PUSCH) and physical random access channel (PRACH), respectively, and downlink transport channels DL-SCH, BCH and PCH are mapped to physical downlink shared channel (PDSCH), physical broadcast channel (PBCH) and PDSCH, respectively. In the PHY layer, uplink control information (UCI) is mapped to physical uplink control channel (PUCCH), and downlink control information (DCI) is mapped to physical downlink control channel (PDCCH). The UE sends MAC PDU related to UL-SCH via PUSCH based on UL grant, and the BS sends MAC PDU related to DL-SCH via PDSCH based on DL assignment.
[0110] Hereinafter, contents related to a Multi Universal Subscriber Identity Module (MUSIM) are described.
[0111] Multi-USIM devices (eg, MUSIM devices 810) are becoming more and more popular in different countries. A user can have both a personal subscription and a business subscription in one device, or have two personal subscriptions in one device for different services.
[0112] Figure 8 An example of a wireless environment in which a MUSIM device operates according to an embodiment of the present disclosure is shown.
[0113] Reference Figure 8 , the MUSIM device 810 (or MUSIM UE 810) may have multiple Universal Subscriber Identity Modules (USIMs) - USIM1 811 (or USIM A 811) and USIM2 813 (USIM B 813). The MUSIM device 810 may register with network 1 (or network A) 820 based on subscription information in USIM1 811 to obtain connection A 825 between network 1 820 and the MUSIM device 810. The MUSIM device 810 may also register with network 2 (or network B) 830 based on subscription information in USIM2 813 to obtain connection B 835 between network 2 830 and the MUSIM device 810. The MUSIM device 810 may use USIM1 811 to perform communication with network 1 820 through connection A 825, and use USIM2 813 to perform communication with network 2 830 through connection B 835.
[0114] In a wireless environment in which a MUSIM device operates, the following properties may hold true:
[0115] - Each registration to the USIMS from a MUSIM device can be handled independently.
[0116] - Each registered USIM in a MUSIM device may be associated with a unique International Mobile Equipment Identity (IMEI) / Permanent Equipment Identifier (PEI).
[0117] - A MUSIM UE can connect to i) an Evolved Packet System (EPS) on one USIM and a 5G System (5GS) on another USIM; ii) EPS on both USIMs; or iii) 5GS on both USIMs.
[0118] -MUSIM UE can be single receive (RX) / dual RX / single transmit (TX) / dual TX UE. Single RX may allow MUSIM UE to receive traffic from only one network at a time. Dual RX may allow MUSIM UE to receive traffic from two networks simultaneously. Single TX may allow MUSIM UE to send traffic to one network at a time. Dual TX may allow MUSIM UE to send traffic to two networks simultaneously. The terms single RX / TX and dual RX / TX do not refer to device types. As an example, a single UE may use dual TX in some cases and single TX in other cases.
[0119] - If / when multiple USIMs in a MUSIM device are served by different serving networks, network coordination between the serving networks may not be required.
[0120] - MUSIM devices with different USIMs may reside on the same serving network RAN node with all USIMs, or MUSIM devices may reside on different serving network RAN nodes.
[0121] - The USIMs may belong to the same or different operators. No coordination between the operators involved may be required.
[0122] - The USIM can be a physical SIM or an embedded SIM (eSIM).
[0123] When actively communicating with the first system / network, the MUSIM UE may need to periodically monitor the second system / network (e.g., synchronize, read a paging channel, perform measurements, or read system information). Depending on the UE implementation (i.e., single receive (Rx) or dual Rx), the periodic activity on the second system may or may not have a performance impact on the first system with which the UE is communicating.
[0124] In some cases, UEs equipped with different USIMs may have paging conflicts resulting in lost paging. When a UE receives a paging in a second system while actively communicating with a first system, the UE may need to decide whether the UE should respond to the paging. When the UE decides to respond to the paging in the second system, the UE may need to stop the current activity in the first system. For example, the first system may suspend or release an ongoing connection with the UE.
[0125] For MUSIM operation, a MUSIM device in the RRC_CONNECTED state in network A may have to switch from network A to network B. For example, a MUSIM device in the RRC_CONNECTED state in network A may perform a network switch from network A to network B (or, perform a SIM switch from a SIM associated with network A to a SIM associated with network B) based on a paging received from network B, and establish a connection with network B (and enter RRC_CONNECTED in network B). Herein, network A may be NR, and network B may be E-UTRA or NR. Before switching from network A, the MUSIM device should notify network A or leave the RRC_CONNECTED state, or remain in the RRC_CONNECTED state in network A while temporarily switching to network B.
[0126] For example, when configured to do so, the MUSIM device may signal a preference to leave the RRC_CONNECTED state by using RRC or NAS signaling to network A. After sending a preference to leave the RRC_CONNECTED state by using RRC signaling, if the MUSIM device does not receive an RRCRelease message from network A within a certain period of time (configured by network A), the MUSIM device may enter the RRC_IDLE state in network A.
[0127] For example, when configured to do so, the MUSIM device may signal to network A a preference to temporarily switch to network B while maintaining the RRC_CONNECTED state in the network. This is indicated by a scheduling gap preference. The preference may include information to set or release gaps. Network A may configure up to 4 gap patterns for MUSIM purposes: three periodic gaps and a single aperiodic gap. Network A shall always provide at least one of the requested gap pattern or no gaps. The network may provide an alternative gap pattern instead of the gap pattern requested by the UE.
[0128] In the present disclosure, if the capability of the UE does not support simultaneous execution of an operation on a first resource and an operation on a second resource, it may be referred to as a capability conflict between the first resource and the second resource, and / or a conflict between the first resource and the second resource. For example, in MUSIM operation, a capability conflict may occur between a first resource in network A associated with USIM A and a second resource in network B associated with USIM B.
[0129] For the case where multiple USIMs in a multi-USIM device are served by different service networks, the solution to the capability conflict in the MUSIM operation does not require network coordination. That is, the capability conflict in the MUSIM operation may be a conflict that cannot be resolved by network coordination between network A and network B, and / or a conflict based on the inability of network A and network B to coordinate resources to resolve the conflict, and / or a conflict between a first resource and a second resource that network A and network B cannot coordinate.
[0130] Meanwhile, the Multiple USIM (MUSIM) function is intended to support a situation where UEs in SIM A (ie, network A) and SIM B (ie, network B) simultaneously establish each RRC connection and send / receive data.
[0131] In this case, from the perspective of network A, due to the RRC connection establishment of network B, the UE may suffer a temporary hardware conflict between the serving cell of network B and the CA / DA configuration of network A. This is because the frequency of the serving cell on network B may conflict with some serving frequencies of CA / DC on network A. If a temporary hardware conflict occurs, the UE may not be able to use some resources of the problematic CA / DC configuration until the RRC connection release of network B and / or the serving cell of network B is changed.
[0132] The problem is that if the UE requests resolution of a temporary hardware conflict after the temporary hardware conflict occurs, some data may be delayed until the temporary hardware conflict is resolved.
[0133] Therefore, the present disclosure provides various implementations for UE to notify network A of the temporary hardware conflict before it occurs, thereby shortening the period during which some resources of CA / DC configuration cannot be used due to the temporary hardware conflict as much as possible and improving data transmission delay.

[0147] According to various embodiments, recognizing that the capability conflict is resolved may include at least one of: recognizing that a connection with the second network has been released; or recognizing that a service frequency of the second network associated with the second resource has been changed.

If the previous capability conflict is resolved, the UE may enable the disabled first radio resource in the first network.
[0152] Fig.10An example of a signal flow between a UE and a network node according to an embodiment of the present disclosure is shown. The network node may include a base station (BS).
[0153] Reference Fig.10 In step S1001, a network node in a first network may establish a connection with a UE.
[0154] In step S1003, a network node in the first network may communicate with the UE based on the first resource.
[0155] In step S1005 , while a connection between a network node in a first network and the UE is established, the UE may detect an event of establishing a connection with a second network.
[0156] In step S1007, after detecting an event of establishing a connection with the second network, the UE may identify a capability conflict between a first resource used in the first network and a second resource used in the second network.
[0157] In step S1009 , the UE may autonomously disable the first resource based on identifying the capability conflict.
[0158] In step S1011, a network node in the first network may receive disabling information related to disabling a first resource from a UE.
[0159] According to an implementation of the present disclosure, while performing multi-USIM operations, when the UE pre-confirms that an RRC connection needs to be established / restored in network B, if the UE determines that the frequency of the camped cell to be used as the serving cell on network B will cause a conflict with at least one serving frequency of network A, the UE can autonomously stop using resources related to at least one serving frequency of network A, and the UE can report to network A that due to the conflict during multi-USIM operations on network B, the UE autonomously stops using resources for the serving cell (i.e., resources configured for the serving frequency of network A).
[0160] The resources may include radio resources of one or more serving cells configured for the corresponding network. For network A, if configured, the UE may use the radio resources of the serving cell for CA / DC operation. For network B, if configured, the UE may use the radio resources for the serving cell / camping cell.
[0161] In order to check whether a conflict occurs due to multi-USIM operation, before the UE successfully completes the RRC connection establishment / recovery in network B, the UE may determine in advance whether any resources configured by network A may cause problems such as incomplete configuration and / or capability conflicts with resources in network B.
[0162] In order to pre-confirm that an RRC connection needs to be established / restored in network B, the condition may include at least one of the following:
[0163] - when the UE has received a paging message from the network B, and / or
[0164] - When the UE checks whether a voice call service is initiated on network B via the paging cause in the paging message.
[0165] Therefore, with these conditions, when the UE has received a paging message from network B and / or when the UE checks whether to initiate a voice call service on network B via the paging cause in the paging message, the UE can check whether any service frequency of network A will suffer a conflict in using resources with the frequency of the currently camped cell on network B.
[0166] In order to autonomously stop using resources related to the problematic service frequency of network A (i.e., to disable resources used in network A), the UE may discard / remove all or part of the cell configuration related to the serving cell in network A, or may release the serving cell in network A, or may deactivate the serving cell in network A. That is, disabling resources may include at least one of the following:
[0167] - Deactivation of a serving cell in network A, for example, SCell deactivation or SCG deactivation;
[0168] - Release of a serving cell in network A, e.g., SCell release or SN release; and / or
[0169] - Switch the active BWP of the serving cell in network A to a BWP configured for temporary cell deactivation.
[0170] After autonomously stopping the use of resources related to the problematic service frequency of network A, the UE may send an indication (i.e., disabling information) to network A that some radio resources have been disabled due to multi-USIM operation. The indication / disabling information may include at least one of the following:
[0171] - which frequencies have conflicts due to multiple USIM operation;
[0172] - which cell has been deactivated due to multi-USIM operation;
[0173] - which cell has been released due to multiple USIM operation;
[0174] - which cell configuration has been removed due to multi-USIM operation; and / or
[0175] - Which BWP has been switched from the previously active BWP due to multi-USIM operation.
[0176] When the UE determines that the autonomously disabled radio resources of network A become enabled (i.e., the connection of network B has been released and / or the service frequency of network B has been changed), the UE may send a second indication to network A through an autonomous action of the UE that the disabled radio resources are available or that the disabled radio resources have been enabled.
[0177] To autonomously enable disabled radio resources, the UE may perform at least one of the following:
[0178] - (re)activation of a serving cell in network A, e.g., SCell (re)activation or SCG (re)activation;
[0179] -Addition of serving cells in network A, for example, SCell addition or SN addition;
[0180] - Handover of a certain BWP of a serving cell in network A to a previously active BWP configured for cell (re)activation.
[0181] Fig.11 An example of a method for active cell restriction of MUSIM according to an embodiment of the present disclosure is shown. The method may be performed by a UE and / or a wireless device.
[0182] Reference Fig.11 In step S1101, the UE may establish an RRC connection toward a first cell in the first network and enter an RRC_CONNECTED state. The first network may allow a request for temporary UE capability restriction due to multi-USIM operation to be sent.
[0183] In the second network, the UE may have camped on the second cell.
[0184] In the first network, the UE may have configured a CA / DC configuration via an RRC reconfiguration message. The UE may activate one or more serving cells for CA / DC according to the received CA / DC configuration.
[0185] In step S1103, the UE may receive a paging message on the second cell in the second network to establish an RRC connection. The paging message may include paging cause information to indicate a voice call service in network B. The UE is still in RRC_IDLE or RRC_INACTIVE state in the second network.
[0186] In step S1105, the UE may detect a capability conflict between the frequency of the second cell on the second network and the frequency of at least one serving cell of the first network. After receiving the paging message on the second network, the UE may check whether at least one frequency associated with one or more serving cells used for CA / DC in network A will have any conflict when the UE enters the RRC_CONECTED state on the second cell of network B. That is, the frequency of the second cell on network B will cause a conflict with the frequency of at least one serving cell of network A.
[0187] In step S1107, the UE may autonomously disable a serving cell on the first network. If there is at least one serving cell whose frequency may cause problems such as incomplete configuration and / or capability conflicts due to an RRC connection to network B, the UE may disable the serving cell to avoid the problem. In order to disable the serving cell, the UE may deactivate the serving cell without network permission (i.e., via UE-based SCell deactivation or UE-based SCG deactivation) to resolve the problem. If the serving cell is an SCell, the UE may perform SCell deactivation. If the serving cell is a PSCell, the UE may perform SCG deactivation.
[0188] In step S1109, after disabling the serving cell, the UE may send an RRC message (e.g., UEAssistanceInformation) to indicate the disabling information (e.g., the serving cell has been disabled due to a conflict problem of multiple USIM operations). In the RRC message, the problematic configuration may be included, for example, which CA / DC configuration will be the problem causing the frequency conflict with the second cell of the second network. The UE may also indicate the frequency of the second cell and / or the second cell information (e.g., cell identity) in the RRC message.
[0189] In step S1111, the UE may establish an RRC connection with the second network. The UE may send an RRC setup or RRC recovery message to the second cell to process the received paging message. After sending the RRC setup or RRC recovery message, the UE may receive an RRC setup or RRC recovery message from the second cell to establish / restore the RRC connection. The UE may successfully complete the RRC connection on the second cell.
[0190] In step S1113, based on establishing the RRC connection with the second network, the UE may receive services from the second network.
[0191] In step S1115, after the service is completed, the UE may release the RRC connection with the second network. For example, the UE may receive an RRC release message from the second cell and release the RRC connection on the second cell.
[0192] In step S1117, the UE may autonomously enable the disabled serving cell on the first network. After RRC release on the second cell of network B, the UE may determine whether the disabled serving cell can be enabled again via the signal quality of RLM or RRM. If the disabled serving cell can be enabled again (i.e., the signal quality of the serving cell is still suitable for access), the UE may reactivate the serving cell without network permission from network A. If the serving cell is an SCell, the UE performs SCell reactivation. If the serving cell is a PSCell, the UE may perform SCG reactivation.
[0193] In step S1119, after activating the serving cell, the UE may send an RRC message (eg, UEAssistanceInformation) to indicate activation information (eg, the serving cell has been reactivated).
[0194] In addition, it can be Figure 2 The first wireless device 100 and / or Figure 3 UE 100 shown in FIG. 1 is used to perform the present disclosure (eg, Fig. 9 The method according to the UE perspective described in (a).
