[0125] Figure 1 An example of a network 100 suitable for use with the examples of this disclosure is schematically illustrated. The network (also referred to as an NW) includes multiple network nodes, including: a terminal node 110 (also referred to as a user equipment UE), an access node 120 (also referred to as a radio access network RAN ​​node or base station), and one or more core network nodes 130. Terminal node 110 and access node 120 communicate with each other. In some, but not necessarily all, examples, one or more core network nodes 130 may communicate with each other. In some, but not necessarily all, examples, one or more access nodes 120 may communicate with each other.

[0126] In this example, network 100 is a radio telecommunications network, i.e., RAN, in which at least some of the terminal nodes 110 and access nodes 120 communicate with each other using radio wave transmission / reception.

[0127] RAN 100 may be a cellular network comprising multiple cells 122, each cell being served by access node 120. Access node 120 includes a cellular radio transceiver. Terminal node 110 includes a cellular radio transceiver.

[0128] In the specific example shown, network 100 could be a new radio NR network of the 3rd Generation Partnership Project (3GPP) and its fifth-generation 5G technology. In other examples, network 100 could be a network other than 5G, such as a next-generation (i.e., sixth-generation, 6G) radio network currently under development (i.e., an NR network and its evolution into 5G technology).

[0129] The interface between terminal node 110 and access node 120 is radio interface 124 (e.g., Uu interface). The interface between access node 120 and one or more core nodes 130 is backhaul interface 128 (e.g., S1 and / or next-generation NG interface).

[0130] Depending on the specific deployment scenario, access node 120 can be a RAN node such as an NG-RAN node. An NG-RAN node can be a gNodeB or gNB that provides NG user plane and control plane protocol termination to the UE. The gNB connects to the 5G core (5GC) via an NG interface, and more specifically, connects to the Access and Mobility Management Function (AMF) via the NG control plane NG-C interface, and connects to the User Plane Function (UPF) via the NG user plane NG-U interface. Access nodes 120 can interconnect with each other via Xn interface 126.

[0131] Cellular network 100 can be configured to operate in licensed or unlicensed frequency bands (especially: unlicensed frequency bands that rely on transmitting equipment to sense radio resources / mediums before transmission begins, such as via the Listen-After-Speak (LBT) process; and 60 GHz unlicensed frequency bands that may require beamforming to achieve the desired coverage).

[0132] Access node 120 can be deployed in NG standalone operation / scenario. Access node 120 can be deployed in NG non-standalone operation / scenario. Access node 120 can be deployed in carrier aggregation (CA) operation / scenario. Access node 120 can be deployed in dual-connectivity DC operation / scenario, i.e., in a dual-connectivity MR-DC with multiple radio access technologies.

[0133] In this non-standalone / dual-connectivity deployment, access nodes 120 can interconnect with each other via X2 or Xn interfaces and connect to the Evolved Packet Core (EPC) via the S1 interface or to the 5GC via the NG interface.

[0134] Terminal node 110 is a user-side network element in the network that terminates the radio link. They are devices that allow access to network services. Terminal node 110 may be referred to as User Equipment (UE), mobile terminal, or mobile station. The term 'User Equipment' can be used to specify a mobile device that includes components for authentication / encryption (such as a smart card) or a Subscriber Identity Module (SIM). The SIM / SIM card can be a memory chip, module, or Universal Subscriber Identity Module (USIM).

[0135] In some examples, the term 'user equipment' can be used to specify a location / location tag, super / smart tag, or mobile device, which includes circuitry systems for authentication / encryption, such as software SIM, embedded as part of the user equipment. The functionality of terminal node 110 can also be performed by a mobile terminal MT, which is part of the integrated access and backhaul (IAB) node.

[0136] Access node 120 is a network element in the network responsible for radio transmission and reception with terminal node 110 in one or more cells 122. Access node 120 is the network terminal of the radio link. Access node 120 can be implemented as a single network device or have a split architecture that is decomposed / distributed across two or more RAN nodes (such as central unit CU, distributed unit DU, remote radio headend RRH) using different functional split architectures and different interfaces.

[0137] In the case where the access node 120 has a decomposed (split) architecture, the access node 120 may include one or more distributed units gNB-DU and centralized units gNB-CU ( Figure 1 (Not shown in the diagram). The gNB-CU is a logical node configured to host the Radio Resource Connection (RRC) layer and other layers of the access node 120. The gNB-CU controls the operation of one or more gNB-DUs. The gNB-DU is a logical node configured to host the Radio Link Control (RLC) protocol layer, Media Access Control (MAC) layer, and Physical PHY layer of the access node 120. The gNB-DU can communicate with the RRC layer hosted by the gNB-CU via a dedicated interface (e.g., an F1 interface). One gNB-DU can support one or more cells 122. A gNB or gNB-DU can host one or more Transmitter Receiver Points (TRPs). gNB-DU functionality can also be performed by the DU portion of the IAB node.

[0138] A UE that can support multiple SIMs is called a User Equipment with Multi-Subscriber Identity Module (MUSIM) UE. A MUSIM UE can simultaneously register / connect to multiple different networks or the same network via each of its multiple SIMs, where each registration / connection corresponds to a different user identity (i.e., the identity of the corresponding different SIM).

[0139] In the following description, the network will be referred to as NW 100, the access node / RAN node 120 will be simply referred to as gNB 120, and the multi-SIM enabled terminal node 110 will be simply referred to as MUSIM UE 110. For simplicity, the example discussed pertains to a dual-SIM enabled UE (dual-SIM UE) with a first SIM and a second SIM. However, it should be understood that the examples of this disclosure can be extended to MUSIM UEs with more than two SIMs.

[0140] When in MUSIM operating mode, the MUSIM UE can support different levels / types of MUSIM:

[0141] 1. Dual SIM Dual Activity DSDA. In this mode, the MUSIM UE can register with two independent subscriber IDs (i.e., SIMs) and can be in the RRC_IDLE state on both SIMs. Furthermore, a MUSIM UE with DSDA capability can maintain RRC_CONNECTED state activity on both SIMs in parallel. In DSDA mode, the MUSIM UE can establish and maintain two active connections in parallel, for example, two simultaneous RRC CONNECTED states, one for each SIM. The two active connections operate independently. These two active connections can potentially perform both RX and TX concurrently, although RX and TX are not necessarily scheduled simultaneously. However, there is no coordination between RX and TX activities between the two active connections because they operate independently. The MUSIM UE can simultaneously: perform TX on both SIMs (TX / TX), perform RX on both SIMs (RX / RX), or perform TX on one SIM and RX on the other SIM (TX / RX). However, TX / TX and TX / RX can cause interference from the transmitter of a DSDA-capable MUSIM UE to the receiver of a DSDA-capable MUSIM UE, referred to as cross-SIM interference / cross-SIM effect / cross-SIM impact, where an operation performed using one SIM (i.e., transmit / receive operations to / from its associated active connection network—TX or RX) affects another SIM (i.e., transmit / receive operations to / from its associated active connection network—TX or RX). The term 'cross-SIM interference' is similar to the recognized self-interference mechanisms of CA and DC operations, although it applies to MUSIM operations. Cross-SIM interference is a term used in this disclosure that is caused by the same mechanisms found in CA and DC, referred to as UE self-interference, but unlike the configuration of self-interference causes chosen by the same network operator, cross-SIM interference can involve network operator-related configurations for each individual SIM of the MUSIM device. This self-interference / cross-SIM interference in MUSIM operations is referred to as cross-SIM interference.

[0142] 2. Dual SIM Dual Standby DSDS. In this mode, the MUSIM UE can register with two independent user IDs (i.e., SIMs) and can be in the RRC_IDLE state on both SIMs. However, at any given time, a MUSIM UE with DSDS capability can only be in the RRC_CONNECTED state with only one SIM. In DSDS mode, the MUSIM UE can maintain fully idle modes (e.g., RRC idle state or RRC inactive state) on both SIMs in parallel and can initiate and maintain an active connection mode on one SIM at a time while maintaining an idle mode on the other SIM. In idle mode, the MUSIM UE with DSDS capability still needs to maintain "service" with the idle network. This means it needs to be ready to establish a connection with the idle network and perform mobility operations. Therefore, the MUSIM UE with DSDS capability must listen to the paging channels(s) from the idle network, for example, to detect potential incoming calls. The MUSIM UE with DSDS capability must occasionally read the System Information Block (SIB) from the idle network to ensure it is using the correct idle mode configuration and monitor neighboring cells when needed to be ready for cell handover.

[0143] DSDS itself can have different modes: a. DSDS, single receiver (DSDS single RX): In this mode, the MUSIM UE needs to prioritize each activity between SIMs. For example, if two SIMs are on different networks, or if two SIMs are on the same network but incoming paging is on different channels / BWPs, it's impossible for both SIMs to listen for incoming paging simultaneously in a single-RX MUSIM UE, and therefore only one paging will be received. The prioritization scheme that prioritizes one SIM / paging over another can be proprietary to each MUSIM UE vendor. b. DSDS, Dual Receiver (DSDS Dual RX): In this mode, a MUSIM UE can receive two SIMs in parallel. However, if one SIM is in active connectivity mode, the TX of the SIM in active connectivity mode may affect the reception quality of the SIM in idle mode (e.g., similar to the carrier aggregation (CA) case outlined in TS 38.101). In this regard, simultaneous TX on one SIM and simultaneous RX on another SIM (i.e., TX / RX) may cause interference from the transmitter of a MUSIM UE with DSDS capability to the receiver of a MUSIM UE with DSDS capability, i.e., cross-SIM interference as described above, in which an operation performed using one SIM (i.e., TX operation on its associated active connectivity network) will affect the operation of the other SIM (i.e., RX operation from its associated idle network).

[0144] For a MUSIM UE supporting DSDA, the MUSIM UE can be in a first active or idle mode via its first SIM and first NW 100_1, and can also be in a second active or idle mode simultaneously via its second SIM and second NW 100_2. In some examples, the DSDA MUSIM UE can be in a first active or idle mode via its first SIM and first NW 100_1, and can also be in a second active or idle mode simultaneously via its second SIM and first NW 100_1.

[0145] Similarly, for a MUSIM UE that supports DSDS, the MUSIM UE can be in active (or idle) mode via its first SIM and first NW 100_1, and can also be in idle (or active) mode via its second SIM and second NW 100_2. In some examples, the DSDS MUSIM UE can be in active (or idle) mode via its first SIM and first NW 100_1, and can also be in idle (or active) mode simultaneously via its second SIM and first NW 100_1.

[0146] Examples of this disclosure relate to MUSIM operation and how a MUSIM UE can help resolve configuration conflicts that are unpredictable for each SIM to connect to the network / network operator. This can include conflicts between operators (i.e., when the MUSIM operation of a MUSIM UE is served by two different network / regional operators), and conflicts that may occur when the same operator serves a MUSIM UE with two active accounts (i.e., two International Mobile Equipment Identity, IMEI) via two SIMs of the same MUSIM UE.

[0147] Figure 2This diagram illustrates a simplified view of spectrum allocation for NW operators. In this example, three operational frequency bands are shown for three different operators. The diagram shows how the three 5G frequency bands contain non-overlapping spectrum or channels (e.g., band numbers: n3, n1, and n78). The operating modes are either TDD or FDD. These frequency bands are both FDD (n1, n3) and TDD (n78).

[0148] Network operators can provide services to UEs through carrier aggregation (CA), which combines spectrum to achieve higher data throughput. This CA combination is declared as CA_n1A-n3A-n78A, where the last letter of the band number indicates the maximum allowed transmission bandwidth of the operating band.

[0149] For UEs with CA enabled in FDD-FDD multi-band operation, both bands typically operate simultaneously in both downlink and uplink. However, certain rules can be applied to configure the uplink UL gap, i.e., the gap in the UL TX from the CA-enabled UE (in the time domain). For UEs with CA enabled in FDD-TDD multi-band combinations, the TDD band can be in uplink mode, while the FDD band can be in downlink operation. For UEs with CA enabled in TDD-TDD multi-band operation, two types of simultaneous RX / TX and non-simultaneous RX / TX operation are defined. The UE is responsible for supporting these possible mode combinations / multi-band operations.

[0150] If the UE supports CA combination, the capabilities specified in simultaneousRxTxInterBandCAxxx need to be considered. The same applies to the E-UTRAN New Radio Dual Connectivity ENDC, where the device can also specify simultaneous RX / TX capabilities. For basic physical layer parameters regarding CA and Dual Connectivity DC operation, please refer to TS 38.306, Section 4.2.7.x.

[0151] However, currently, no such capability is specified in the context of MUSIM operation. This means that during UE registration with the NW and during UE capability exchange, the NW is never informed of the UE's internal use of the hardware HW applicable to MUSIM operation.

[0152] Furthermore, for CA and DC operations, the maximum allowable sensitivity reduction MSD is detailed in the presence of simultaneous TX and RX, as well as in the case of self-interference caused by the UE's TX. However, this capability is not currently given in the context of MUSIM operations.

[0153] Currently, signaling related to MUSIM operation only involves establishing regular and irregular gaps, i.e., time-domain gaps in the UL TX of the active SIM of the MUSIM UE, referred to herein as MUSIM gaps, such as those used to receive paging for an idle SIM. The current definition of MUSIM gap configuration requests is specified in TS38.331.

[0154] Figure 3 The illustration shows an example of a radio architecture designed for a single-SIM UE capable of carrier aggregation (CA). A single-SIM UE includes several antennas and several radio paths (including various front-end modules (FEMs), power amplifiers (PAs), and diversity DIV modules—for low / mid / high frequency bands) to allow the single-SIM UE to establish multiple radio connections simultaneously.

[0155] One limitation of radio architecture is that a single frequency band typically supports only one uplink path per operating band, while the same frequency band can have multiple downlink paths. Figure 3 In the example, the single-SIM UE has two mid-to-high frequency band (MCB) front-end modules (FEMs), which allows the single-SIM UE to support uplinks in two MCBs, while routing uplinks to different antennas or the same antenna based on inter-band uplink CA and continuous / discontinuous intra-band uplink CA. In all these modes, operation is limited to one operator (i.e., one SIM). MUSIM operation, which combines CA with a single-SIM UE, is more complex than CA on a single-SIM UE.

[0156] In DSDS, CA capabilities can be used for dual RX as much as possible, but CA capabilities also explicitly define limitations on when to support dual RX (which frequency bands are combined via each SIM of MUSIM, i.e., cross-SIM frequency band combination).

[0157] Figure 4 The illustration shows cross-SIM interference in a MUSIM configuration with n3 and n78 (i.e., one SIM uses n3 and the other SIM uses n78). Figure 4 Various types of self-interference are shown in this combination of channel allocation within two frequency bands (x-axis n3, y-axis n78), including: a portion of the n3 frequency band in the uplink with 5MHz uplink cross-SIM interference entering the 10MHz downlink and 10MHz uplink cross-SIM interference entering the 20MHz downlink; and a portion of the n3 frequency band in the downlink with 10MHz uplink cross-SIM interference entering the 5MHz downlink.

[0158] As stated above, the term 'cross-SIM interference' is similar to the recognized self-interference mechanisms in CA and DC operations, although it applies to MUSIM operations. Cross-SIM interference is a term used in this disclosure that is caused by the same mechanism found in CA and DC, referred to as UE self-interference, but unlike the configuration of self-interference causes chosen by the same network operator, cross-SIM interference can involve network operator-related configurations for each individual SIM of the MUSIM device. This self-interference / cross-SIM effect in MUSIM operations is referred to as cross-SIM interference.

[0159] Cross-SIM interference may be caused by spurious emissions due to undesirable transmitter effects. Cross-SIM interference can be caused by: second and subsequent harmonics in the MUSIM UE's processing of signals to / from the first SIM versus the MUSIM UE's processing of signals to / from the second SIM, UL harmonic interference, harmonic emissions, parasitic emissions, intermodulation products, and frequency conversion products. Cross-SIM interference may reduce signal reception sensitivity.

[0160] For example, if there is cross-SIM interference from the MUSIM UE's own TX, the defined sensitivity may be reduced by several dB. If the normal sensitivity of the MUSIM UE is -100 dBm, the maximum sensitivity reduction MSD can allow for a reduction of up to 10 dB, resulting in a sensitivity of -90 dBm.

[0161] The MUSIM UE can estimate / determine under what conditions cross-SIM interference will occur and the tolerable level of cross-SIM interference (e.g., the maximum cross-SIM interference threshold level that maintains the RX operating sensitivity reduction within the maximum sensitivity reduction MSD value). In this regard, the MUSIM UE can establish / determine the expected cross-SIM interference conditions (which may be referred to herein as "occurrence of cross-SIM interference") based on the MUSIM UE's TX output power. The MUSIM UE can determine the MSD in a manner roughly similar to how the MSD value is determined based on the CA configuration, which will affect the UE's reference sensitivity.

[0162] Regarding the determination of MSD values ​​based on CA configuration, the following is an excerpt from Table 7.3A.5-1 of Power Class 3 PC3 in TS 38.101-1. This indicates that for CA_n1-n78 CA configurations, the MSD value for the n1 band of PC3 is 8 dB.

[0163] The following is an excerpt from Table 7.3A.5-1a of PC2 in TS 38.101-1. This indicates that for the CA_n1-n78 CA configuration, the MSD value of the n1 band of PC2 is 17.8 dB.

[0164] The dependency between TX output power and MSD is not a 1:1 ratio in dB, but can be estimated / determined, for example, by the UE or programmed in production based on pre-production measurements. This can be indicated by comparing the two MSD values ​​mentioned above. Here, an 8 dB MSD at 23 dBm TX output power increases to an MSD of 17.8 dB at 26 dBm TX power. It can be estimated that at approximately 20 dBm TX output power, there will be no MSD. Therefore, in this case, 20 dBm can be considered a threshold TX output power level at which there will be no MSD, i.e., no MSD due to CA operation.

[0165] The MUSIM UE can determine the expected threshold TX output power level (i.e., no cross-SIM interference) without MSD due to MUSIM operation in a manner roughly similar to the method described above for determining the threshold TX output power level without MSD due to CA operation; although instead of using the CA configuration (the frequency band combination of CA, such as CA_n1-n78), the frequency band / channel configuration of each SIM connection is used.

[0166] Based on the determined MSD value and the knowledge that the MUSIM UE possesses based on the MSD type of the current channel combination, if the MUSIM UE is forced to perform a TX operation to the first RAN node using the first SIM at a TX output power level higher than the threshold output power level, the MUSIM UE can derive a threshold TX output power at which the receiver sensitivity of the MUSIM UE is expected to decrease (i.e., RX operation of the second RAN node using the second SIM).

[0167] The threshold TX output power at which the MUSIM UE is expected to experience a decrease in receive sensitivity is referred to herein as the TX trigger level. The Tx trigger level is defined as the threshold Tx output power level of the first SIM (e.g., the connected SIM), which, from an interference perspective, is the 'attacker' and the MUSIM UE has determined to cause self-interference affecting the receive performance of the second SIM (e.g., the idle SIM), making the second SIM the 'victim' from an interference perspective. The TX trigger level can vary based on signal level, bit error, channel BW, etc., but for simplicity, it can also be the lower limit of the MUSIM UE's sensitivity, such as -99 dBm.

[0168] The occurrence of cross-SIM interference can be determined by identifying a TX output power greater than the TX trigger level. Determining the occurrence of cross-SIM interference may include determining whether cross-SIM interference conditions have been met / exceeded, or determining whether cross-SIM interference is expected to occur, such as whether cross-SIM interference is expected to occur, for example, based on a TX output power greater than the TX trigger level.

[0169] One problem that the examples in this disclosure attempt to address is allowing the network to exchange information, which can be used by, for example, a MUSIM UE, to mitigate cross-SIM interference and resolve MUSIM conflicts in MSD scenarios, until the network is aware of these conflicts (i.e., particularly when the MUSIM UE's SIMs belong to different NW operators and the MUSIM UE is camped on different NWs). Various examples focus on the cases where the MUSIM UE's SIMs belong to different NW operators and the MUSIM UE is camped on different NWs. However, in some examples, the SIMs can belong to the same NW operator.

[0170] Figure 5 An example of method 500 according to the first aspect of this disclosure is schematically illustrated.

[0171] Figure 5 This can be seen as illustrating multiple methods because Figure 5 This can be viewed as a diagram illustrating one or more actions performed by or at multiple actors / entities. Therefore, Figure 5 It can be viewed as a diagram illustrating multiple individual methods performed by each corresponding individual actor / entity among multiple actors / entities.

[0172] In this respect, the method illustrated in the figure and discussed below can be regarded as illustrating the method with respect to the first device (e.g., as referenced). Figure 10 The method corresponding to the action performed by the device 10, which is configured to perform the role of MUSIM UE 110, and the method corresponding to the action performed by the second device (e.g., as referenced) Figure 10 The illustrated device 10 is configured to perform actions corresponding to those of the first gNB 120_1. The functions shown and described can also be performed by a computer program (as referenced). Figure 11 This is achieved through (as described above).

[0173] The MUSIM UE can be configured to simultaneously: be in a connected state with the first RAN node 120_1 using a first SIM (“connected SIM”), and be in an idle state with the second RAN node 120_2 using a second SIM (“idle SIM”). In this regard, the MUSIM UE can be configured to support DSDS operation. In DSDS operation mode, TX operation with the first RAN node using the first SIM may affect RX operation with the second RAN node using the second SIM; this self-interference / cross-SIM effect is referred to as cross-SIM interference.

[0174] In some examples, the first RAN node 120_1 and the second RAN node 120_2 are RAN nodes of different first and second networks. In some examples, the first RAN node and the second RAN node are RAN nodes of the same network.

[0175] although Figure 5 The first RAN node and the second RAN node shown are separate / different RAN nodes, but it should be understood that in some examples, the first RAN node and the second RAN node can be the same RAN node.

[0176] In block 501, the MUSIM UE sends information to the first RAN node 120_1 indicating the MUSIM UE's ability to switch between a first operating mode and a second operating mode. The first operating mode is the MUSIM UE's operating mode, wherein at least one gap is provided in at least one transmission from the MUSIM UE to the first RAN node to enable the MUSIM UE to receive signals from the second RAN node using a second SIM. The second operating mode is a MUSIM multiple standby multiple receive mode, such as DSDS dual RX.

[0177] Capability information can indicate the MUSIM UE's ability to dynamically switch between modes based on a determined cross-SIM interference level. Although not shown in the figure, the MUSIM UE can also send such capability information to the second RAN node 120_2.

[0178] In block 502, the MUSIM UE receives authorization information from a first RAN node indicating whether the MUSIM UE is permitted to switch between a first operating mode and a second operating mode. The authorization information may instruct the MUSIM UE to dynamically decide for itself whether to switch between modes based on the MUSIM UE's determination of the occurrence of cross-SIM interference (e.g., at least based on scheduled TX operations using the first SIM / connected SIM and simultaneous RX operations using the second SIM / idle SIM, such as receiving paging signals). The determination of whether the first RAN node grants permission may be based at least in part on capability information received in block 501, such that dynamic mode switching authorization is provided based on whether the MUSIM UE has the capability to perform dynamic mode switching.

[0179] Alternatively, if such permission is not granted, the MUSIM UE can receive control information from the first RAN node to force the MUSIM UE into a first operating mode, such as a network management gap.

[0180] In block 503, MUSIM UE 110 determines a TX power threshold / TX trigger level, which indicates an estimate of the transmission output power of the transmission from MUSIM UE to the first RAN node that is expected to cause cross-SIM interference. The execution of block 503 can be triggered / responded to by the establishment of a connection mode, for example, MUSIM UE establishing a first connection mode via its first SIM (not shown).

[0181] In block 504, MUSIM UE 110 sends information to the first RAN node indicating the determined TX power threshold / TX trigger level.

[0182] In some examples, this TX power threshold / TX trigger level information may be sent to the first RAN node along with a request for MUSIM gap configuration information. This MUSIM gap configuration information includes information for configuring the MUSIM UE to provide one or more gaps in TX operations from the MUSIM UE to the first RAN node using the first SIM / connection SIM, wherein such gaps may be used for RX operations on the second SIM / idle SIM (i.e., receiving paging signals from the second RAN node via the second SIM).

[0183] In block 505, the first RAN node determines MUSIM gap configuration information for configuring the MUSIM UE to provide one or more gaps. The determination of the MUSIM gap configuration information may be based at least in part on the TX power threshold / TX trigger level information received in block 504.

[0184] In box 506, the MUSIM UE receives MUSIM gap configuration information from the first RAN node.

[0185] In response to receiving MUSIM gap configuration information, the MUSIM UE can send an acknowledgment message to the first RAN node, indicating confirmation of the received requested MUSIM gap configuration information. The acknowledgment message may include the latest / most recently determined TX power threshold / TX trigger level. This allows the first RAN node to determine what TX power output from the MUSIM UE is expected to cause cross-SIM interference (i.e., cause cross-SIM interference), and thus trigger the MUSIM UE to switch between the first mode and the second mode.

[0186] In some examples, the MUSIM UE can receive requests for monitoring and reporting TX power threshold information from a first RAN node and / or a second RAN node. Similarly, such information allows the RAN nodes to determine the TX output power level that will trigger a mode transition for the MUSIM UE.

[0187] In block 507, the MUSIM UE determines which of the first and second modes it wants to be in. In this regard, the MUSIM UE can determine whether to switch between the first and second operating modes. This determination can be in response to the MUSIM UE determining that cross-SIM interference has occurred due to the transmission output power of a scheduled transmission from the MUSIM UE to the first RAN node exceeding the TX power threshold / TX trigger level. This determination can also be based at least in part on the authorization information received in block 502, i.e., such that the MUSIM UE only determines whether to switch modes when authorized / permitted.

[0188] In this respect, the MUSIM UE can compare the TX output power of the TX operation on the first SIM / connected SIM with the TX power threshold / TX trigger level (e.g., the TX power threshold / TX trigger level as previously determined in block 503 and reported to the first RAN node in block 504).

[0189] If the TX output power is greater than the TX power threshold / TX trigger level, the MUSIM switches to the first operating mode, that is, at least one gap is provided in the TX operation on the first SIM / connected SIM to enable the RX operation (e.g., receiving a paging signal) on the second SIM / idle SIM.

[0190] If the TX output power is less than the TX power threshold / TX trigger level, MUSIM switches to the second operating mode, i.e., DSDA with dual RX.

[0191] existFigure 5 In the example shown, it is assumed that the TX output power is greater than the TX power threshold / TX trigger level, and in response to this, MUSIM transitions to the first operating mode that provides the MUSIM gap.

[0192] In box 508, a MUSIM gap is created. This gap can be provided by the network or determined by the MUSIM UE itself. This gap can be a network-managed gap, such as one provided based on the MUSIM gap configuration received in box 506. In this respect, the MUSIM UE applies the received MUSIM gap configuration and applies the MUSIM gap to its transmissions.

[0193] In box 509, the MUSIM UE receives an idle state signal, such as a paging signal, from the second RAN node during the MUSIM interval.

[0194] Figure 5 The examples illustrate one possible scenario. The order of the boxes shown is not strictly necessary; therefore, in principle, the boxes can be executed out of order. Not all boxes are essential. In some examples, one or more boxes may be executed in a different order, or may overlap in time, be executed sequentially, or be executed in parallel. One or more boxes may be omitted, added, or changed in some combination.

[0195] In some examples, the MUSIM UE can send a report to the first RAN node indicating whether the MUSIM UE has transitioned between a first operating mode and a second operating mode. The MUSIM UE can also send the first RAN node the TX power threshold / TX trigger level used when determining the occurrence of cross-SIM interference during the transition between modes.

[0196] Advantageously, method 500 provides a framework that enables the MUSIM UE to dynamically switch between network-managed MUSIM gaps and being in DSDS-RX mode. If cross-SIM interference is low (i.e., the TX output power level of the MUSIM UE does not cause cross-SIM interference), the MUSIM UE will not generate gaps during TX operations on the first SIM / connected SIM. However, if the TX output power level of the MUSIM UE causes cross-SIM interference at an unacceptable level, reaching a threshold level, the MUSIM UE can automatically switch to creating a gap.

[0197] MUSIM UEs can use the MSD value to derive the TX trigger level, which is used to trigger / determine when to create a gap and when to stop creating a gap, all of which depend on the actual cross-SIM interference level.

[0198] By providing the ability to dynamically switch between providing and not providing MUSIM gaps based on cross-SIM interference levels (i.e., by operating in DSDS dual RX mode), this advantageously allows MUSIM gaps to be used only when needed, which reduces the gaps required in DSDS mode. This provides benefits to MUSIM UEs as well as to each connected and idle network.

[0199] Examples of this disclosure may allow the use of the UE radio path based on checking for cross-SIM interference (i.e., checking for cross-SIM interference / self-interference), rather than applying the traditional strict rules of mandatory gap MUSIM operation, or even prohibiting dual RX operation.

[0200] Figure 6 Another example of the method 600 according to the first aspect of this disclosure is schematically illustrated. The figure illustrates the operations and signaling performed by the MUSIM UE 110, the first network 100_1, and the second network 100_2.

[0201] exist Figure 6 In the illustrated use case, the MUSIM UE 110 includes a first SIM (referred to as the "connected SIM") in an active connected mode with a first network (referred to as the "connected mode network"). The MUSIM UE 110 also includes a second SIM (referred to as the "idle SIM") in an idle mode with a second network (referred to as the "idle network").

[0202] Figure 6 The illustration shows an example of how to use the TX trigger level as the basis for signaling to select between using gaps or dual RX. It should be understood that the reference to signals sent to / from each SIM and the actions performed by each SIM involve signaling and actions performed by the MUSIM UE itself (not the SIM itself), although the signaling / actions of the MUSIM UE are related to one of the SIMs (e.g., MUSIM UE signaling sent to a connected mode network using a connected SIM).

[0203] In box 1, the idle SIM notifies the designated idle network of its MUSIM UE capabilities, including information about its ability to dynamically switch between MUSIM gaps and dual RX for idle SIM RX operations configured by the network.

[0204] In box 2, the Connecting SIM notifies the MUSIM UE of its ability to communicate with the specified Connectivity Mode network, including information about its ability to dynamically switch RX operations for the Idle SIM between MUSIM gaps and dual RX. This box effectively corresponds to... Figure 5Box 501. The Connected SIM can also report to the Connected Mode network when the MUSIM UE switches between the two modes and the level of self-interference that causes the handover.

[0205] In box 3, connect the SIM card to enter connection mode.

[0206] In box 4, the Connected SIM receives an RRC (reconfiguration) from the Connected Mode network. The RRC (reconfiguration) may contain information indicating possible CA and MUSIM configurations. The RRC configuration may also contain information indicating whether the MUSIM UE is authorized / permitted to perform MUSIM operation using dynamic handover between gaps and dual RX. This transmission of authorization information effectively corresponds to... Figure 5 Box 502. If the connected network does not allocate / control gaps for the MUSIM UE, the MUSIM UE may be forced to generate gaps itself in order to maintain idle mode with the idle network on an idle SIM.

[0207] In box 5, in response to receiving RRC (re)configuration in box 4, a MUSIM UE procedure is triggered, where the TX trigger level is determined / updated by determining whether cross-SIM interference / self-interference may be a problem between the TX channel configuration of the connected SIM and the RX channel configuration of the idle SIM. This box effectively corresponds to Figure 5 The box number is 504.

[0208] In box 6, the Connected SIM sends UE assistance information to the Connected Mode Network. This may include information indicating cross-SIM interference estimation, such as the TX trigger level to be used to determine whether to dynamically switch into / out of MUSIM gap mode (where the MUSIM UE will query the Connected Mode Network for the dynamic switching gap(s) configuration). This transmission of the TX trigger level can effectively correspond to Figure 5 The box number is 504.

[0209] Alternatively, in box 7, the information indicating the cross-SIM interference estimation mentioned in box 6 (i.e., the TX trigger level) can be sent to the connected-mode network via an RRC message (i.e., in the RRC reconfiguration complete message). This transmission of the TX trigger level can effectively correspond to... Figure 5 The box number is 504.

[0210] In box 8, the connected SIM receives an RRC reconfiguration message from the connected-mode network. This message includes the new CA and MUSIM configuration, including a configuration with MUSIM gaps. This box can effectively correspond to... Figure 5 Box 506.

[0211] In box 9, after the reconfiguration is applied, the connecting SIM sends an acknowledgment of it to the connecting mode network, i.e., via an RRC reconfiguration completion message. The new / current / latest TX trigger level can also be reported based on the MUSIM UE procedure (similar to the procedure mentioned in step 5) involved in the RRC reconfiguration based on box 8.

[0212] In box 10, it is determined that the TX output power level from the connected SIM for TX operation rises above the TX trigger level (which will therefore cause cross-SIM interference / self-interference).

[0213] In box 11, update the connected SIM TX level in the idle SIM.

[0214] In box 12, the idle SIM determines that an RX operation is required (e.g., for receiving a paging from an idle mode network). The idle SIM performs the idle SIM RX operation using a MUSIM gap to require the connected SIM to create a MUSIM gap at least in the TX. The connected SIM RX may be unaffected.

[0215] In block 13, since the TX level is higher than the TX trigger level, the MUSIM UE determines that the MUSIM gap during TX operation on the connected SIM is necessary for RX operation on the idle SIM; that is, the MUSIM UE determines that it should be in the first operating mode that provides the MUSIM gap. This determination effectively corresponds to... Figure 5 Box 507. The connected SIM creates a desired gap for RX operation of the idle SIM. In this respect, the gap can be managed by the network (i.e., the connected SIM requests a gap to be scheduled from the connected network), or if the connected network does not allocate / control the gap, the MUSIM UE may be forced to generate the gap itself in order to maintain idle mode with the idle network on the idle SIM. Box 13 effectively corresponds to Figure 5 Box 508.

[0216] In box 14, the gap is used to receive paging from an idle network serving an idle SIM. This box effectively corresponds to... Figure 5 Box 509.

[0217] In box 15, it is determined that the TX level drops below the TX trigger level.

[0218] In box 16, an update is performed on the idle SIM at the TX trigger level.

[0219] In box 17, the new TX trigger level and the optional MUSIM operation level are reported to the connection network by the connection SIM.

[0220] In box 18, the idle SIM determines that another RX operation is needed (e.g., receiving another paging). The idle SIM uses DSDS dual RX for the RX operation (because the RX operation is not affected by any connected SIM TX operation).

[0221] In box 19, the connected SIM continues to operate normally; that is, in DSDS dual RX mode, no gaps are created for idle SIM RX operations.

[0222] In box 20, the DSDS dual RX is used to receive paging from an idle network serving an idle SIM.

[0223] Figure 6 The examples illustrate one possible scenario. The order of the boxes shown is not strictly necessary; therefore, in principle, the boxes can be executed out of order. Not all boxes are essential. In some examples, one or more boxes may be executed in a different order, or may overlap in time, be executed sequentially, or be executed in parallel. One or more boxes may be omitted, added, or changed in some combination.

[0224] In the example according to the method described above, the MUSIM UE can notify both the connected network and the idle network of its ability to dynamically handover between two operations: a network management gap (i.e., gap-configured RX) for idle SIM RX operation and a dual RX for idle SIM RX operation. The connected network can configure the MUSIM UE to force it to use a gap or allow it to use dynamic dual RX (i.e., allow the MUSIM UE to dynamically handover between a network management gap or dual RX for idle SIM RX operation). When the MUSIM UE handovers between dual RX and gap-configured RX, it can also notify the connected network. It can also notify the connected network of the expected self-interference level that leads to the handover via the transmission of TX power threshold information.

[0225] The examples disclosed herein may allow the use of UE radio paths based on UE capabilities and determined / expected cross-SIM interference (i.e., checking for cross-SIM interference / self-interference), rather than applying the traditional strict rules of mandatory gap MUSIM operation, or even prohibiting dual RX operation. The examples may also provide the network(s) with an awareness of the challenges of cross-SIM interference configuration, which may lead to the adoption of mitigation schemes on the network side to ensure optimal DSDS operation at the MUSIM UE.

[0226] Figure 7 An example of method 700 according to the second aspect of this disclosure is schematically illustrated.

[0227] The method illustrated in the figure and discussed below can be considered as an illustration of the method with respect to the first device (e.g., as referenced). Figure 10The method corresponding to the actions performed by the device 10 (which is configured to perform the role of a MUSIM UE). The functions shown and described can also be performed by a computer program (as referenced). Figure 11 This is achieved through (as described above).

[0228] The MUSIM UE can be configured to simultaneously: be in a first connection state with a first RAN node using a first SIM, and be in a second connection state with a second RAN node using a second SIM. In this respect, the MUSIM UE can be configured to support DSDA operation. (This is consistent with the first aspect of this disclosure.) Figure 5 and Figure 6 Similar to the example above, TX operation using the first SIM to the first RAN node may affect RX operation using the second SIM from the second RAN node. This self-interference / cross-SIM effect is again referred to as cross-SIM interference. The MUSIM UE can estimate / determine under what conditions cross-SIM interference will occur and the tolerable level of cross-SIM interference (e.g., the maximum cross-SIM interference threshold level that maintains the RX operation sensitivity reduction within the maximum sensitivity reduction MSD value). As mentioned above, the maximum threshold level of cross-SIM interference can be represented by the TX trigger level, i.e., the maximum TX output power that the MUSIM UE can apply to TX operation on the connected SIM.

[0229] In box 701, the MUSIM UE determines whether it is experiencing cross-SIM interference; that is, it determines whether the cross-SIM interference conditions have been met.

[0230] In block 702, in response to determining that the MUSIM UE is experiencing cross-SIM interference (i.e., in response to determining that the cross-SIM interference condition has been met), the MUSIM UE sends channel configuration information to one of the first RAN node and the second RAN node. The channel configuration information includes information indicating the channel configuration between the MUSIM UE and the other of the first and second RAN nodes. The channel configuration information can be TX channel configuration information or RX channel configuration information. The TX channel can be referred to as the "attacker channel" because it causes cross-SIM interference, while the RX channel can be referred to as the "victim channel" because it is affected by cross-SIM interference caused by the attacker channel (i.e., the MUSIM UE's reception sensitivity is reduced).

[0231] In block 703, the MUSIM UE receives channel reconfiguration information from one of the first RAN node and the second RAN node. This channel reconfiguration information is used to reconfigure the transmission or reception of signals to or from either the first or second RAN node, wherein the transmitted channel reconfiguration signal is at least partially based on the received channel configuration information. The reconfiguration information may include information for reconfiguring the channel between the MUSIM UE and either the first or second RAN node.

[0232] In some examples, the channel configuration information of box 701 and / or the reconfiguration information of box 703 include information indicating at least one of the following: Bandwidth portion BWP location; Channel allocation, Channel bandwidth, or Uplink component carrier.

[0233] In some examples, determining whether the cross-SIM interference condition is met in step 702 includes at least one of the following: Determine whether the expected level of interference to the transmission or reception of the first signal by the MUSIM UE due to the transmission or reception of the second signal by the MUSIM UE exceeds a threshold. Determine whether the expected sensitivity level of the receiver of the MUSIM UE used to receive one of the first and second signals has exceeded a threshold level; Determine whether the maximum sensitivity reduction MSD parameter value has exceeded the threshold; Determine whether the transmission output power of at least one of the first and second signals has exceeded a threshold level; or Determine whether the power margin parameter value has exceeded the threshold.

[0234] In some examples, the MUSIM UE (before executing blocks 701-702) receives first configuration information from a first RAN node, which configures the MUSIM UE to send or receive a first signal to or from the first RAN node using the first SIM. The MUSIM UE can also receive second configuration information from a second RAN node, which configures the MUSIM UE to send or receive a second signal to or from the second RAN node using the second SIM.

[0235] In some examples, the MUSIM UE can determine whether cross-SIM interference conditions are met based at least in part on the received first and second configuration information, for example, based on the TX or RX channel configuration and the scheduling resources allocated by the first and second RAN nodes to determine whether cross-SIM interference exists.

[0236] In some examples, the first RAN node is also the second RAN node. In other examples, the first RAN node and the second RAN node are different.

[0237] In some examples, the first RAN node and the second RAN node (which may be the same RAN node) belong to the same NW. In other examples, the first RAN node is a RAN node of a first NW, and the second RAN node is a RAN node of a different second NW.

[0238] Advantageously, method 700 enables the MUSIM UE to provide information to one of the first RAN node and the second RAN node (and thus to its respective first NW and second NW) in response to the determination of cross-SIM interference, wherein such information includes channel information about the other of the first RAN node and the second RAN node (i.e., in practice, such channel information associated with one RAN node is sent to the other / relative RAN node).

[0239] In some examples, the information provided to the other / peer RAN node (and therefore to the corresponding other / peer NW to which the other / peer RAN node belongs) can provide the peer network with information about the attacker and victim channels, the type of self-interference mechanism, the type of intermodulation distortion (IMD) (such as IMD4), the order of MSD types, and the MSD value. It should be understood that the first RAN node and the second RAN node can be the same RAN node and / or belong to the same NW, but the NW may not be aware that it is serving two SIMs for the MUSIM UE.

[0240] The examples disclosed herein enable multiple NWs to be notified (e.g., via UE assistance information or RRC (re)configuration completion messages) that a MUSIM UE is experiencing cross-SIM interference, and to be notified of information indicating the configuration of other SIMs of the MUSIM UE (e.g., the TX or RX channel configuration of other SIMs). With such information, the multiple NWs can utilize the information received by the multiple NWs regarding the conflicting frequency bands (and channels, etc.) at the MUSIM UE to seek to mitigate cross-SIM interference problems by reconfiguring the uplink (attacker SIM) or downlink (victim SIM).

[0241] Advantageously, the examples of this disclosure can provide NW awareness of MUSIM UE challenges in cross-SIM interference configurations, which can enable mitigation schemes on the NW side to seek improvements to MUSIM operation at the MUSIM UE, such as DSDA operation.

[0242] Figure 8Another example of method 800 according to the second aspect of this disclosure is schematically illustrated.

[0243] Figure 8 This can be seen as illustrating multiple methods; in a sense, Figure 8 This can be viewed as a diagram illustrating one or more actions performed by multiple actors / entities. Therefore, Figure 8 It can be viewed as a diagram illustrating multiple individual methods performed by each corresponding individual actor / entity among multiple actors / entities.

[0244] In this respect, the method illustrated in the figure and discussed below can be regarded as illustrating the method with respect to the first device (e.g., as referenced). Figure 9 The method corresponding to the actions performed by the device 10, which is configured to perform the role of MUSIM UE 110, and the method corresponding to the actions performed by the second device (e.g., reference) Figure 9 The described apparatus 10, configured to perform the function of gNB 120_1, corresponds to the method of operation. The functions shown and described can also be performed by a computer program (as referenced). Figure 10 This is achieved through (as described above).

[0245] In the example shown, the MUSIM UE is a DSDA-enabled UE that is connected to the first RAN node 120_1 using the first SIM and connected to the second RAN node using the second SIM.

[0246] In some examples, the first RAN node and the second RAN node are RAN nodes of different first and second networks. In other examples, the first RAN node and the second RAN node are RAN nodes of the same network.

[0247] In some examples, the first RAN node and the second RAN node are the same RAN node. In other examples, the first RAN node and the second RAN node are different.

[0248] In block 801, the MUSIM UE sends information to the first RAN node 120_1 indicating the MUSIM UE's ability to transmit channel information of the second RAN node (i.e., the MUSIM UE's ability to transmit configuration information of the RX or TX channel between the MUSIM UE and the second RAN node with which the MUSIM UE is actively connected via the MUSIM UE's second SIM). Although not shown in the figure, the MUSIM UE can also send such information to the second RAN node 120_2.

[0249] In box 701, the MUSIM UE determines whether the cross-SIM interference condition has been met (i.e., similar to the above). Figure 7 (As discussed in the text).

[0250] In box 702, in response to determining that the cross-SIM interference condition has been met, the MUSIM UE sends channel configuration information to the first RAN node, wherein the channel configuration information includes information indicating the channel configuration between the MUSIM UE and the second RAN node (i.e., similar to the above). Figure 7 (As discussed in the text).

[0251] In block 802, in response to receiving channel configuration information from the second RAN node, the first RAN node uses this information to determine channel reconfiguration information for reconfiguring the MUSIM UE's transmit or receive signals. The reconfiguration information can be determined with reference to the second RAN node's channel configuration information, i.e., to mitigate cross-SIM interference to the second RAN node's channel from the MUSIM UE using the second SIM.

[0252] In box 703, the MUSIM UE receives channel reconfiguration information from the first RAN node. This channel reconfiguration information is used to reconfigure the transmission or reception of signals to and from the first RAN node, wherein the received channel reconfiguration information is at least partially based on received channel configuration information (i.e., similar to the information above). Figure 7 (As discussed in the text).

[0253] In box 803, the MUSIM UE applies the channel reconfiguration information received from the first RAN node.

[0254] In some examples (not shown), the MUSIM UE receives a request from the first RAN node to monitor and report the TX output power level. Such a TX output power level may correspond to a transmission to the second RAN node using the second SIM and / or a transmission to the first RAN node using the first SIM. In response to such a request, the MUSIM UE may continue to monitor and report the TX output power level.

[0255] Figure 9 Another example of the method 900 according to the second aspect of this disclosure is schematically illustrated. The figure illustrates the operations and signaling performed by the MUSIM UE 110, the first network 100_1, and the second network 100_2.

[0256] exist Figure 9 In the illustrated use case, MUSIM UE 110 is a DSDA UE that includes a first SIM (referred to as "Connection SIM 1") capable of being in active connection mode with a first network (referred to as "Connection Mode Network 1"). MUSIM UE 110 also includes a second SIM (referred to as "Connection SIM 2") capable of being in active connection mode with a second network (referred to as "Connection Mode Network 2").

[0257] Figure 9 The illustration shows an example of signaling that sends information about a network to another network in response to the determination of cross-SIM self-interference. Such information could be about an attacker network to a victim network (where the attacker network corresponds to a network to which the MUSIM UE sends signals using one of its SIMs, and such signal transmission would cause cross-SIM interference to the transmission or reception of signals using another SIM to another / victory network). Similarly, such information could be about a victim network to an attacker network.

[0258] It should be understood that the reference to signals sent to / from each SIM and the actions performed by each SIM involve signaling and actions performed by the MUSIM UE itself (not the SIM itself), although the signaling / actions of the MUSIM UE are related to one of the SIMs (e.g., MUSIM UE signaling sent to the connected mode network using the connected SIM).

[0259] In box 1, the MUSIM UE's connecting SIM 1 sends information about the MUSIM UE's capabilities to the network serving the connecting SIM 1 (i.e., the connection mode network 1). This capability information may include the MUSIM UE's DSDA capability, i.e., the MUSIM UE's support for simultaneous RX / TX and operating modes (FDD-FDD, FDD-TDD, TDD-TDD). This capability information may also include whether the MUSIM UE can notify the connection mode network 1 of cross-SIM interference issues (i.e., cross-SIM interference or self-interference issues) in the DSDA scenario (as discussed further below). This capability information can be sent via a UE capability information message. This box effectively corresponds to... Figure 9 Box 901.

[0260] In box 2, the MUSIM UE's connecting SIM 2 also sends information about the MUSIM UE's capabilities to its serving network (i.e., connection mode network 2). This capability information may include the MUSIM UE's DSDA capabilities and whether the MUSIM UE can notify connection mode network 1 of cross-SIM interference issues in DSDA scenarios. Similarly, this capability information can be sent via a UE capability information message.

[0261] It should be understood that connection mode networks 1 and 2 can be the same network. However, since the network will see both SIMs individually, both SIMs need the ability to notify the network of the MUSIM UE separately and individually.

[0262] In box 3, SIM 1 enters connection mode with connection mode network 1.

[0263] In box 4, SIM 1 receives channel configuration in the RRC reconfiguration message.

[0264] In box 5, Connecting SIM 1 notifies Connecting SIM 2 of the channel configuration of the Connecting SIM.

[0265] In box 6, SIM 2 is connected to enter connection mode with connection mode network 2.

[0266] In box 7, SIM 2 receives channel configuration in the RRC reconfiguration message.

[0267] In box 8, the channel configuration of the connected SIM 2 is notified to the connected SIM 1. The MUSIM UE needs to take this channel configuration into account in any activity involving the connected SIM 1 and the connected SIM 2.

[0268] In box 9, based on a comparison of the two receive channel configurations, each connected SIM (i.e., the MUSIM UE itself) can determine / establish the existence of cross-SIM interference issues / self-interference. Each connected SIM (i.e., the MUSIM UE itself) can also determine which SIM is the attacker (i.e., which SIM is performing a TX operation that affects the RX operation of another SIM) and which SIM is the victim (i.e., which SIM is performing an RX operation affected by the TX operation of another SIM). In this example, connected SIM 2 is the attacker (TX), and connected SIM 1 is the victim (RX). This box effectively corresponds to... Figure 7 Box 701.

[0269] In box 10, Connecting SIM 2 notifies Connecting Mode Network 2 of the victim (RX) channel configuration of Connecting SIM 1. This box effectively corresponds to... Figure 7 Box 702.

[0270] In box 11, it is now up to the connectivity-mode network 2 to determine whether to seek mitigation of cross-SIM interference / self-interference. The connectivity-mode network 2 can use information from the connectivity SIM 2 to determine potential changes to the TX configuration (BWP location, channel allocation, channel bandwidth, uplink component carrier (CA or DC)) that could mitigate cross-SIM interference issues. If the connectivity-mode network 2 changes the TX configuration of the MUSIM UE, any such reconfiguration of the MUSIM UE will effectively correspond to... Figure 7 Box 703.

[0271] In box 12, Connecting SIM 1 notifies Connecting Mode Network 1 of the channel configuration of the attacker (TX) of Connecting SIM 2. This box effectively corresponds to... Figure 7 Box 701.

[0272] In box 13, it is now up to the connectivity-mode network 1 to determine whether to seek mitigation of self-interference. The connectivity-mode network 1 can use information from the connectivity SIM 1 to determine potential changes to the RX configuration (BWP location, channel allocation, channel bandwidth, downlink timeslot), which can mitigate cross-SIM interference issues. If the connectivity-mode network 1 wants to change the RX configuration of the MUSIM UE, any such reconfiguration of the MUSIM UE will effectively correspond to... Figure 7 Box 703.

[0273] Figure 9 The examples illustrate one possible scenario. The order of the boxes shown is not strictly necessary; therefore, in principle, the boxes can be executed out of order. Not all boxes are essential. In some examples, one or more boxes may be executed in a different order, or may overlap in time, be executed sequentially, or be executed in parallel. One or more boxes may be omitted, added, or changed in some combination.

[0274] The above-described example of the second aspect of this disclosure, such as in the DSDA use case, provides updated signaling to allow (multiple) networks to mitigate cross-SIM interference / self-interference between two SIMs operating simultaneously in connected mode. This is achieved by providing the appropriate network on which each SIM is operating (e.g., the appropriate network serving each SIM) with information about the uplink (TX) attacker and self-interference (RX) victim of the MUSIM UE. One SIM may operate on one network, while another SIM may operate on a different network. For all use cases, it is impossible to assume or predict which SIM is operating on which network, as this is entirely up to the end user to decide.

[0275] Each of the first and second aspects relates to the operation of the MUSIM UE and addresses the challenge of resolving configuration conflicts that network operators cannot predict. These conflicts can occur between different regional operators serving the MUSIM UE, or within the same operator when multiple active accounts (i.e., IMEIs) exist on a single MUSIM UE (e.g., via multiple SIMs). Examples of this disclosure allow for information exchange with (multiple) networks to help resolve cross-SIM interference, i.e., MUSIM conflicts in self-interference scenarios during MUSIM operation.

References to computer programs, instructions, code, etc., should be understood to encompass software or firmware used with programmable processors, such as the programmable content of hardware devices, whether instructions for the processor or configuration settings for fixed-function devices, gate arrays, or programmable logic devices, etc.

[0316] As used in this application, the term 'circuit system' may refer to one or more or all of the following: (a) Hardware circuit implementation only (such as implementation in analog and / or digital circuit systems only) and (b) A combination of hardware circuitry and software, such as (if applicable): (i) A combination of (multiple) analog and / or digital hardware circuits and software / firmware, and (ii) Any part of a hardware processor (including digital signal processors), software, and memory (including multiple memory) having software, which work together to enable a device such as a mobile phone or server to perform various functions, and (c) (Multiple) hardware circuits and / or (multiple) processors, such as (multiple) microprocessors or a portion thereof, which require software (e.g., firmware) to operate, but may be absent when the software is not required to operate.

[0317] This definition of circuit system applies to all uses of the term in this application, including in any claim. As another example, as used in this application, the term circuit system also covers only the implementation of hardware circuits or processors and their accompanying software and / or firmware. For example, if applicable to a particular claim element, the term circuit system also covers baseband integrated circuits for mobile devices, or similar integrated circuits in servers, cellular network devices, or other computing or networking devices.

[0318] Although specific terms are used in this article, they are used only in a general and descriptive sense, and not for restrictive purposes.

[0319] The features described above can be used in combinations other than those explicitly described.

[0320] Although some features have been described with reference to certain characteristics, these functions can be performed by other features, whether or not they are described.

[0321] While features have been described with reference to certain examples, these features may also exist in other examples, whether or not they are described. Therefore, a feature associated with one example / aspect of the invention may include any or all features associated with another example or aspect of the invention, and vice versa, provided they do not contradict each other.

[0322] Although various examples of this disclosure have been described in the preceding paragraphs, it should be understood that modifications may be made to the given examples without departing from the scope of the invention as set forth in the claims.

[0323] The term 'comprise' as used in this document is inclusive rather than exclusive. That is, any reference to X that includes Y means that X may include only one Y or may include more than one Y. If the intention is to use 'comprise' with an exclusive meaning, it will be clearly stated in the context by referring to 'comprising only one' or using 'consisting'.

[0324] In this specification, 'connection,' 'coupling,' and 'communication,' and their derivatives, refer to operational connection / coupling / communication. It should be understood that any number or combination of intermediate components (including no intermediate components) may be present to provide direct or indirect connection / coupling / communication. Any such intermediate component may include hardware and / or software components.

[0325] As used herein, the term "determine" (and its grammatical variations) can include at least: calculating, processing, deriving, measuring, investigating, identifying, searching (e.g., searching in a table, database, or other data structure), confirming, etc. Furthermore, "determine" can include receiving (e.g., receiving information), retrieving / accessing (e.g., retrieving / accessing data in memory), obtaining, etc. Additionally, "determine" can include parsing, selecting, picking, building, inferring, etc.

[0326] As used herein, descriptions of actions should also be considered as disclosing enabling, and / or causing, and / or controlling the action. For example, a description of transmitting information should also be considered as disclosing enabling, causing, and / or controlling the transmission of information. Similarly, for example, a description of a means of transmitting information should also be considered as disclosing that at least one component or controller of the means enables and / or causes and / or controls the means of transmitting information.

[0327] The term "component" as used in the specification and claims may refer to one or more individual elements configured to perform one or more corresponding described functions, or it may refer to several elements performing such functions. Furthermore, the functions described in the claims may be performed by the same individual components or a combination of the same components. For example, performing one or more such functions in a device may be caused by a processor executing instructions stored in the memory of the device.

[0328] Unless explicitly stated otherwise (unless the context requires otherwise), references to parameters or parameter values ​​should be understood as referring to data that indicates, defines, or represents the relevant parameter / parameter value. Data may indicate the relevant parameter / parameter value in any way, and may indicate the relevant parameter / parameter value directly or indirectly.

[0329] Various examples are referenced in this specification. Descriptions of features or functions associated with an example indicate that such features or functions exist in that example. The use of the terms 'example,' 'for example,' 'maybe,' or 'can' in the text indicates (whether explicitly stated or not) that such features or functions exist at least in the described example, whether or not they are described as examples, and that they may, but not necessarily, exist in some or all other examples. Therefore, 'example,' 'for example,' 'maybe,' or 'can' refers to a specific instance of a class of examples. An instance's properties can be properties of only that instance, properties of the class, or properties of subclasses of the class that include some, but not all, instances of that class.

[0330] In this specification, unless otherwise expressly stated, references to “a / an / that” [feature, element, component, part, etc.] have an inclusive rather than exclusive meaning and should be interpreted as “at least one” [feature, element, component, part, etc.]. That is, unless the context explicitly states otherwise, any reference to X including a / that Y indicates that X may include only one Y or may include more than one Y. If the exclusive meaning of 'a', 'an', or 'that' is intended to be used, it will be explicitly stated in the context. In some cases, 'at least one' or 'one or more' may be used to emphasize an inclusive meaning, but the omission of these terms should not be construed as inferring any exclusive meaning. As used herein, “at least one of the following: ” and “at least one of ” and similar wording (where the list of two or more elements is connected by “and” or “or”) means at least any one of these elements, or at least any two or more of these elements, or at least all of these elements.

[0331] The presence of a feature (or combination of features) in a claim is a reference to that feature or combination of features itself, and also a reference to a feature (equivalent feature) that achieves substantially the same technical effect. Equivalent features include, for example, features that are variations and achieve substantially the same result in substantially the same manner. Equivalent features include, for example, features that perform substantially the same function in substantially the same manner to achieve substantially the same result.

[0332] In this specification, various examples are referenced, and adjectives or adjective phrases are used to describe the characteristics of the examples. Such descriptions of characteristics associated with examples indicate that the characteristic exists exactly as described in some examples and substantially as described in others.

[0333] In this specification, the described apparatus may alternatively or additionally include an apparatus that, in some other examples, comprises a distributed system of apparatuses, such as a client / server device system.
