Description

Technical Field

[0001] This document is generally directed to a multiple universal subscriber identity module (USIM) solution for wireless communications. Background Art

[0002] Multiple Universal Subscriber Identity Module (USIM) devices may be allowed to connect to two independent networks simultaneously. In this case, the networks may have temporary capability limitations (e.g., regarding bandwidth or multiple-input multiple-output (MIMO) layers) to avoid temporary capability conflicts. For example, if the temporary capability limitations are not known, the first network may continue the data transmission using the original configuration with full capabilities, which may result in demodulation failure and data loss. Therefore, in order to effectively use the user equipment (UE) capabilities, a capability coordination scheme for multiple USIM devices between the two networks may be desirable.

[0040] This specification describes various embodiments of systems, apparatuses, devices, and methods for wireless communications involving a multiple global subscriber identity module solution.

[0041] Figure 1 A schematic diagram of an example wireless communication system 100 is shown, which includes a plurality of communication nodes (or simply nodes) configured to wirelessly communicate with each other. Typically, the communication nodes include at least one user equipment 102 and at least one wireless access node (also referred to herein as a network or network node) 104. Figure 1 The example wireless communication system 100 in FIG. 1 is shown as including two user devices 102, including a first user device 102(1) and a second user device 102(2), and two wireless access nodes 104, including a first wireless access node 104(1) and a second wireless access node 104(2). However, other examples of the wireless communication system 100 may include any various combinations of one or more user devices 102 and / or one or more wireless access nodes 104.

[0042] In general, user equipment as described herein, such as user equipment 102, may include a single electronic device or apparatus capable of wireless communication over a network, or multiple (e.g., a network of) electronic devices or apparatuses (e.g., a network of electronic devices or apparatuses). A user equipment may include or be referred to as a user terminal, user terminal device, or user equipment (UE). In addition, the user device may be or include, but is not limited to, a mobile device (such as a mobile phone, smart phone, smart watch, tablet computer, laptop computer, vehicle or other transportation (powered by human power, motor or engine, such as a car, airplane, train, ship or bicycle as a non-limiting example) or a fixed or stationary device (such as a desktop computer or other computing device that is not usually moved for a long time, such as an appliance, other relatively heavy devices including the Internet of Things (IoT), or a computing device used in a commercial or industrial environment as a non-limiting example). In various embodiments, the user device 102 may include a transceiver circuit 106 coupled to an antenna 108 to implement wireless communication with the wireless access node 104. The transceiver circuit 106 may also be coupled to a processor 110, and the processor 110 may also be coupled to a memory 112 or other storage device. The memory 112 may store therein instructions or code that, when read and executed by the processor 110, causes the processor 110 to implement the various methods described herein.

[0043] Furthermore, generally speaking, a wireless access node (e.g., wireless access node 104) as described herein may include at least one device, electronic, and / or network device or apparatus, and may include one or more base stations or other wireless network access points capable of wirelessly communicating with one or more user devices and / or one or more other wireless access nodes 104 over a network. For example, in various embodiments, the wireless access node 104 may include at least one of a 4G LTE base station, a 5G NR base station, a 5G central unit base station, a 5G distributed unit base station, a next generation Node B (gNB), an enhanced Node B (eNB), or other similar or next generation (e.g., 6G) base station, or a location management function (LMF). The wireless access node 104 may include a transceiver circuit 114 coupled to an antenna 116, which may include various antenna towers 118, to enable wireless communication with the user device 102 or another wireless access node 104. The transceiver circuit 114 may also be coupled to one or more processors 120, which may also be coupled to a memory 122 or other storage device. The memory 122 may store therein instructions or code that, when read and executed by the processor 120 , cause the processor 120 to implement one or more of the methods described herein.

[0044] In addition, in various embodiments, two communication nodes in the wireless system 100, such as a user device 102 and a radio access node 104, two user devices 102 without a radio access node 104, or two radio access nodes 104 without a user device 102, can be configured to wirelessly communicate with each other in accordance with one or more standards and / or specifications in or through a mobile network and / or a radio access network. In general, the standards and / or specifications may define rules or procedures by which communication nodes may communicate wirelessly, and in various embodiments, these rules or procedures may include rules or procedures for communicating in millimeter (mm) bands and / or utilizing multiple antenna schemes and beamforming capabilities. Additionally or alternatively, the standards and / or specifications may be those defining radio access technologies and / or cellular technologies, such as, by way of non-limiting example, Fourth Generation (4G) Long Term Evolution (LTE), Fifth Generation (5G) New Radio (NR), or New Radio Unlicensed (NR-U).

[0045] Furthermore, in the wireless system 100, communication nodes are configured to wirelessly transmit signals between each other. In general, communication between two communication nodes in the wireless system 100 can be or include transmission or reception, and typically simultaneously, depending on the perspective of the particular nodes in the communication. For example, for a given communication between a first node and a second node, where the first node transmits a signal to the second node and the second node receives a signal from the first node, the first node can be referred to as a source or transmitting node or device, the second node can be referred to as a destination or receiving node or device, and the communication can be considered as transmission by the first node and reception by the second node. Of course, since the communication nodes in the wireless system 100 can both send and receive signals, a single communication node can be both a transmitting / source node and a receiving / destination node, or switch between being a source / transmitting node and a destination / receiving node.

[0046] Furthermore, a specific signal may be characterized or defined as an uplink (UL) signal, a downlink (DL) signal, or a sidelink (SL) signal. An uplink signal is a signal transmitted from user equipment 102 to wireless access node 104. A downlink signal is a signal transmitted from wireless access node 104 to user equipment 102. A sidelink signal is a signal transmitted from one user equipment 102 to another user equipment 102, or a signal transmitted from one wireless access node 104 to another wireless access node 104. Furthermore, for sidelink transmission, the first / source user equipment 102 transmits the sidelink signal directly to the second / destination user equipment 102 without forwarding any sidelink signal to the wireless access node 104.

[0047] Furthermore, signals transmitted between communication nodes in the system 100 may be characterized or defined as data signals or control signals. In general, a data signal is a signal that includes or carries data, such as multimedia data (e.g., voice and / or image data), and a control signal is a signal that carries control information that configures the communication nodes in a particular manner to communicate with each other, or controls how the communication nodes transmit data signals to each other. Furthermore, certain signals may be defined or characterized by a combination of data / control and uplink / downlink / sidelink, including uplink control signals, uplink data signals, downlink control signals, downlink data signals, sidelink control signals, and sidelink data signals.

[0048] For at least some specifications, such as 5G NR, data and control signals are transmitted and / or carried on physical channels. Typically, a physical channel corresponds to a set of time-frequency resources used for signal transmission. Different types of physical channels can be used to transmit different types of signals. For example, a physical data channel (or only a data channel) is used to transmit data signals, and a physical control channel (or only a control channel) is used to transmit control signals. Example types of physical data channels include, but are not limited to, a physical downlink shared channel (PDSCH) for transmitting downlink data signals, a physical uplink shared channel (PUSCH) for transmitting uplink data signals, and a physical sidelink shared channel (PSSCH) for transmitting sidelink data signals. In addition, example types of physical control channels include, but are not limited to, a physical downlink control channel (PDCCH) for transmitting downlink control signals, a physical uplink control channel (PUCCH) for transmitting uplink control signals, and a physical sidelink control channel (PSCCH) for transmitting sidelink control signals. As used herein for simplicity, unless otherwise specified, a particular type of physical channel is also used to refer to a signal transmitted on that particular type of physical channel and / or a transmission on that particular type of transmission. As an example, PDSCH refers to the physical downlink shared channel itself, a downlink data signal transmitted on the PDSCH, or a downlink data transmission. Thus, a communication node transmitting or receiving the PDSCH means that the communication node is transmitting or receiving a signal on the PDSCH.

[0049] In addition, for at least some specifications, such as 5G NR, and / or for at least some types of control signals, the control signals transmitted by the communication nodes may include control information, which includes information necessary to enable the transmission of one or more data signals between the communication nodes and / or to schedule one or more data channels (or one or more transmissions on the data channels). For example, such control information may include information necessary to correctly receive, decode, and demodulate data signals received on a physical data channel during data transmission, and / or information for informing a user equipment of an uplink scheduling grant regarding resources and a transmission format for uplink data transmission. In some embodiments, the control information includes downlink control information (DCI) transmitted in the downlink direction from the radio access node 104 to the user equipment 102. In other embodiments, the control information includes uplink control information (UCI) transmitted in the uplink direction from the user equipment 102 to the radio access node 104, or sidelink control information (SCI) transmitted in the sidelink direction from one user equipment 102(1) to another user equipment 102(2).

[0050] In addition, in some embodiments, the user device 102 may be or may be configured as a multi-universal subscriber identity module (USIM) device. As used herein, the term "multi-USIM user device" refers to a multi-USIM device or a user device configured as a multi-device or having multi-USIM capabilities. Typically, the multi-USIM user device 102 may include or use at least two USIMs to connect to multiple independent networks. Each USIM is an entity that includes at least user information (e.g., an international mobile subscriber identifier, or a mobile station international subscriber directory number), and / or encryption and integrity protection information. In any of the various embodiments, the USIM may include other or additional information. In addition, in some embodiments, the multi-USIM user device may use multiple USIMs in any of a variety of applications, such as for personal and business services, respectively, and / or may use a USIM with lower data transmission costs.

[0051] In addition, in some embodiments, the multi-USIM user device 102 can be configured with dual transmitters and dual receivers (dual Tx / dual Rx). Dual Tx / dual Rx allows multiple USIM devices to transmit / receive traffic to / from two independent networks simultaneously. However, in some cases, dual Tx / dual Tx operation may cause one or more problems. For example, the frequency band of the first network of the two independent networks (also referred to as network A in this article) and the frequency band of the second network of the two independent networks (also referred to as network B in this article) may not be able to work together (for example, due to interference), or some original capabilities (for example, capabilities that rely on the combination of operating frequency bands) may no longer be supported. The capability coordination scheme for multi-USIM user devices described herein can overcome these problems.

[0052] Furthermore, as the number or total amount of frequency band combinations that the user device 102 can support continues to increase, the network 104 may not need to obtain the capabilities of all frequency band combinations supported by the user device 102. When requesting the capabilities of the user device 102 during a registration process, the wireless access node (e.g., the network) 104 may send a frequency band list (or frequency band filter) that includes frequency bands of interest to the network 104, and the user device 102 may report the frequency band combinations whose frequency bands are included in the user device capability list / filter.

[0053] For illustration, assume that user device 102 supports four frequency band combinations: BC1: (X+Y+Z); BC2: (Z+O); BC3: (X+P); and BC4: (O+P). Furthermore, assume that the frequency band list sent from network 104 to user device 102 includes: Band X, Band O, and Band P. Furthermore, assume that in this case, user device 102 reports BC3 and BC4 to network 104: BC3: (X+P); BC4: (O+P). If user device 102 is a multi-USIM user device, depending on whether the frequency bands of network B are included in the UE capability filter requested by network A, either the frequency bands of network B are included in the UE capability filter requested by network A (Case 1) or the frequency bands of network B are not included in the UE capability filter requested by network A (Case 2). For Case 1, the frequency band combination including the frequency bands of network B may be stored in network A during the registration process. The user equipment 102 may report the index of the allowed or applied frequency band combination and the index of the allowed or applied capability combination (e.g., feature set combination) to network A. However, for case 2, the above solution is no longer applicable because network A does not know the supported frequency band combinations and the corresponding capabilities related to the frequency bands of network B.

[0054] Furthermore, in some embodiments or environments, for dual-active states, network A may need to modify its capabilities / configuration due to certain reasons, such as data transmission requirements, mobility, or signal quality degradation. For example, network A may require greater bandwidth for data transmission, and conversely, network A may want to switch from one capability combination (e.g., capability combination A) to another capability combination (e.g., capability combination B). The capability renegotiation scheme described herein may be used in conjunction with such embodiments or environments.

[0055] Figure 2 A flowchart of an example method 200 for wireless communication involving multi-USIM capabilities is shown. At block 202, a multi-USIM user device 102 including a first USIM configured to connect to a first network 104(1) (also referred to herein as network A) and a second USIM configured to connect to a second network 104(2) (also referred to herein as network B) may report to the first network 104(1) one or more available frequency band combinations that can operate with a frequency band of the second network 104(2) and corresponding capabilities. Typically, when the first USIM operates (or runs) on the available frequency band combination to perform a first data transmission in the first network 104(1) and the second USIM operates (or runs) on the frequency band to perform a second data transmission in the second network 104(2), the available frequency band combination operates with the frequency band of the second network 104(2) such that the first data transmission and the second data transmission do not, or do not substantially, interfere with each other. Accordingly, at block 202, the multi-USIM user device 102 may determine one or more available frequency band combinations, wherein for each available frequency band combination, the multi-USIM user device 102 determines that transmissions on the available frequency band combination in the first network 104(1) do not or do not substantially interfere with transmissions on a frequency band in the second network 104(2).

[0056] At block 204, the multi-USIM user device 102 may determine a selected frequency band combination and corresponding capabilities selected by the first network 104(1) or the second network 104(2) based on one or more available frequency band combinations.

At block 504, the multi-USIM user device 102 may determine, based on the request to modify the measurement configuration restrictions, selected measurement configuration restrictions selected by the first network or the second network. At block 506, at least one of the first USIM or the second USIM may be reconfigured according to the selected measurement configuration restrictions.

At block 604, at least one of the first network 104(1) or the second network 104(2) may transmit a reconfiguration message to reconfigure at least one of a first USIM or a second USIM of a multi-USIM user device 102. The reconfiguration message may indicate a selected frequency band combination selected based on the one or more available frequency band combinations.

At block 902, the first network 104(1) may transmit a request to modify measurement configuration restrictions.

[0082] Further details that may be part of any of methods 200 , 300 , 400 , 500 , 600 , 700 , 800 , and / or 900 are now described.

[0083] In some embodiments, the multi-USIM user device 102 may coordinate capabilities between network A and network B to ensure that the configuration of the user device 102 in the USIM of network A (referred to as USIM A) and the USIM of network B (referred to as USIM B) does not exceed the maximum capabilities of the user device 102. For at least some embodiments, the capabilities to be coordinated include capabilities related to frequency band combinations and capabilities related to measurements.

[0084] Figure 10 The interactive flow chart of BC capability negotiation is shown. In this document, the term "negotiation" refers to the first or initial instance in which two entities (e.g., USIMA and USIMB) coordinate their capabilities. Correspondingly, the term "renegotiation" refers to subsequent instances after the first instance in which the two entities coordinate their capabilities. Figure 10As shown, in a first step (step 1), a multi-USIM user device 102 connects to network A, for example, via its USIM A. In a second step (step 2), USIM B of the multi-USIM user device 102 may determine or need to enter an active state on a frequency band outside the UE capability filter requested by network A. In a third step (step 3), the multi-USIM user device 102 may determine one or more available BCs and corresponding capabilities of network A. In a fourth step (step 4), the multi-USIM user device 102 may send the one or more available BCs and corresponding capabilities to network A via a message. For at least some embodiments, the message may include at least one of frequency band information or capability information. In some of these embodiments, the frequency band information may indicate supported frequency band combinations. Each supported frequency band combination may include a frequency band of network B. Additionally or alternatively, the frequency band information may include a list of frequency bands in each frequency band combination. In some embodiments, the frequency band list in each frequency band combination may include a list of allowed frequency bands and / or a list of prohibited frequency bands for network A. Additionally or alternatively, the capability information may include capabilities that depend on the operating band combination (per BC capabilities), including at least one of the following: carrier aggregation (CA) capabilities (e.g., CA-parameters NR), dual connectivity (DC) capabilities (e.g., multi-radio access technology parameters (MRDC-parameters)), or power capabilities (e.g., PowerClass). Additionally or alternatively, the capability may depend on a specific frequency band of the operating band combination (per feature set capability). Additionally or alternatively, the capability may depend on a specific component carrier (CC) on a given frequency band in the operating band combination (per feature set per CC capability).

[0085] Furthermore, in some embodiments, this message is sent when USIM B is to enter an active state on a frequency band outside the UE capability filter requested by network A, and the multi-USIM user equipment 102 is to update the BC information and corresponding capabilities of network A. Additionally or alternatively, in some embodiments, this message is sent after the multi-USIM user equipment 102 is to report UE capabilities for multi-USIM purposes.

[0086] Additionally or alternatively, in some embodiments, capability information is defined as at least one of: per band combination level, per feature set level, or per feature set per carrier component level.

[0087] Additionally or alternatively, in some embodiments, the message is a radio resource control (RRC) message or a medium access control control element (MAC CE).

[0088] Additionally or alternatively, BC information may be transmitted using one of the following methods. In the first method, the multi-USIM user device 102 may report available BCs that can operate with the frequency bands of network B. For at least some embodiments of the first method, the reported available BCs do not include the frequency bands of network B. That is, the reported available BCs do not include the frequency bands of network B. In the second method, the multi-USIM user device 102 may report available BCs that include the frequency bands of network B and other frequency bands. In the second method, the frequency band report of the second network includes available BCs for the frequency bands of network B and other frequency bands. That is, the reported available BCs may include one or more frequency bands of network A and one or more frequency bands of network B. The multi-USIM user device 102 may indicate the allowed frequency band list and / or prohibited frequency band list of network A in each frequency band combination.

[0089] Additionally or alternatively, network A may select a suitable BC from the reported available BC list, and network A may send a reconfiguration message with the selected band combination information and the updated configuration information to the multi-USIM user equipment 102 (step 5). For at least some embodiments, the selected band combination information may be a band list of the selected band combination, or a position of the selected band combination in the reported available BC list.

[0090] In one example, when the frequency band of network B is not included in the UE capability filter requested by network A, the multi-USIM user device 102 can report one or more available BCs and corresponding capabilities to network A. For simplicity, only one available BC is reported in this example. However, in other similar examples, the multi-USIM user device 102 can report multiple (two or more) available BCs, each of which has a corresponding set of capabilities. For example, BC1 is associated with capability 1, BC2 is associated with capability 2, and so on. In addition, each band combination BC can be a combination of one or more frequency bands, and each frequency band can be associated with one or more feature sets. In turn, a band combination of one or more frequency bands can correspond to one or more feature sets for one or more bands.

[0091] Furthermore, in this example, it is assumed that the multi-USIM user device 102 operates at BC(X+Y) of network A, and the frequency band of network B is labeled as band Z. The frequency band combination with band Z is (X+Y+Z): (wherein band X and band Y are included in the UE capability filter, while band Z is not included in the UE capability filter). Figure 11 A schematic diagram showing BC(X+Y+Z) and corresponding feature set combinations for this example is shown.

[0092] In addition, in some embodiments where the first method is used to send BC information, the multi-USIM user device 102 may report the (X+Y) component of the frequency band combination (X+Y+Z) and the corresponding applicable feature set to network A. In this example, the frequency band combination and the corresponding feature set sent to network A are as follows:

[0093]

[0094] Furthermore, in some embodiments using the second method for transmitting BC information, the multi-USIM user device 102 may report the frequency bands (X+Y+Z) and the corresponding applicable feature sets to network A. At the same time, the multi-USIM user device 102 may indicate to network A which frequency band(s) may be used in each frequency band combination. In particular, in these embodiments, the multi-USIM user device 102 may report network A's allowed frequency band list or prohibited frequency band list in each frequency band combination. In this example, the frequency band combinations and corresponding feature sets sent to network A are as follows:

[0095]

[0096] In addition, in some embodiments where the second method is used to send BC information, the multi-USIM user equipment 102 may indicate the applicable frequency band of network A. In at least some of these embodiments, the applicable frequency band may be indicated according to one or more of the following:

[0097] Allowed frequency band list = X + Y;

[0098] Allowed Band List = [0][1] (where the multi-USIM user equipment 102 indicates the position of the applicable band in the band list for a given band combination);

[0099] Forbidden Band List = Z; or

[0100] Forbidden Band List = [2] (where the multi-USIM user equipment 102 indicates the position of the forbidden bands in the band list for a given band combination).

[0101] Furthermore, in some embodiments, network A may modify its Business Capability (BC) and / or Feature Set. In the first scenario (Scenario A), network A only modifies its Feature Set. In the second scenario (Scenario B), network A modifies both its Business Capability (BC) and the corresponding Feature Set. In the first scenario (Scenario A), where network A only modifies its Feature Set, the multi-USIM user device 102 may accordingly switch from the original capability set to a different capability set (e.g., feature set entries) without modifying the feature set contents. For example, network A may want to switch from a first capability set to a second capability set. Furthermore, if network A modifies its Business Capability (BC), the multi-USIM user device 102 may accordingly switch to a different BC from the original.

[0102] Figure 12A and Figure 12B The corresponding interaction flow chart of the BC capability renegotiation scheme when network A decides to modify only its feature set is shown. Figure 12A and Figure 12B In the first step (step 1), USIM A and USIM B of the multi-USIM user device 102 may be in an activated state. In the second step (step 2), network A may determine to modify its feature set. In the third step (step 3), network A may send one or more preferred feature sets to the multi-USIM user device 102 via a request to modify message. In some embodiments, the request to modify message may include the position of the preferred feature set in the feature set combination (e.g., a feature set entry). In addition, the modification request message may also be a renegotiation request message, or be included in a renegotiation request message, such as Figure 12A and Figure 12B shown.

[0103] In some embodiments, the request to modify message is sent when USIM A and USIM B are in active state and network A decides to modify its feature set (ie, switch from one feature set to another).

[0104] Additionally or alternatively, the message may be an RRC message or a MAC CE.

[0105] In step 4, the multi-USIM user equipment 102 determines whether to accept the modification request. Figure 12A In , the multi-USIM user equipment 102 determines to accept the modification request. Figure 12B In the case of the multi-USIM user equipment 102, the modification request is rejected. Figure 12A and Figure 12B Described in further detail.

[0106] Specific reference Figure 12AIn step 4, if the multi-USIM user equipment 102 determines to accept the modification request, then in step 5, the multi-USIM user equipment 102 may send an acceptance indication to network B. In some embodiments, the acceptance indication may be an RRC message or a MAC CE. In addition, for at least some embodiments in step 5, the multi-USIM user equipment 102 may send the updated feature set of network B. In addition, for at least some embodiments in step 5, network A and network B may send respective reconfiguration messages to USIM A and USIM B, respectively. In some embodiments, in step 6, the user equipment 102 performs the reconfiguration process on USIM A and USIM B simultaneously. In other embodiments, when network B receives the updated feature set in step 5, in response, network B may release the connection with the multi-USIM user equipment 102, or continue with the original configuration (if the updated capabilities still meet the needs of current communication).

[0107] Specific reference Figure 12B On the other hand, if the multi-USIM user equipment 102 determines in step 4 to reject the modification request, the multi-USIM user equipment 102 may send a rejection indication to network A (step 5). In various embodiments, the rejection indication may be an RRC message or a MAC CE message.

[0108] Figure 12C and Figure 12D FIG. 4 shows a corresponding interaction flow chart of another BC capability renegotiation scheme when network A determines to modify only its feature set. Figure 12C and Figure 12D The BC capability scheme in is similar to Figure 12A and Figure 12B In addition to the scheme in Figure 12C and Figure 12D In the solution in FIG. 1 , the multi-USIM user device 102 does not decide whether to accept or reject the modification request. Instead, the multi-USIM user device 102 delegates the decision to network B.

[0109] For more details, refer to Figure 12C and Figure 12D , the first three steps are similar to Figure 12A and Figure 12BThat is, in the first step (step 1), USIMA and USIMB of the multi-USIM user device 102 may be in an activated state. In the second step (step 2), network A may determine to modify its feature set. In the third step (step 3), network A may send one or more preferred feature sets to the multi-USIM user device 102 via a request modification message. In some embodiments, the request modification message may include the position of the preferred feature set in the feature set combination (e.g., a feature set entry). In addition, the modification request message may also be a renegotiation request message, or included in a renegotiation request message, such as Figure 12C and Figure 12D shown.

[0110] In step 4, in some embodiments, the multi-USIM user device 102 does not determine or decide whether to accept or reject the modification request. Instead, the multi-USIM user device 102 lets network B make the decision. Therefore, in step 5, the multi-USIM user device 102 sends a modification request to network B with the feature set requested by network A.

[0111] Specific reference Figure 12C In step 5, if network B accepts the modification request, network B may send a reconfiguration message with an acceptance indication to the multi-USIM user device 102. For at least some embodiments, the multi-USIM user device 102 may store the reconfiguration message received from network B. In step 6, the multi-USIM user device 102 may send an acceptance indication to network A. In step 7, network A may send a reconfiguration message to USIM A of the multi-USIM user device 102. In step 8, USIM A and USIM B may be reconfigured, for example, based on the reconfiguration message. For at least some embodiments, USIM A and USIM B are reconfigured simultaneously.

[0112] Specific reference Figure 12D In step 5, if network B rejects the modification request, network B may send a rejection indication to the multi-USIM user equipment 102. In response, the multi-USIM user equipment 102 may send a rejection indication to network A.

[0113] Additionally or alternatively, in some embodiments, in order to avoid frequent temporary capability limitation changes, the multi-USIM user equipment 102 may use a timer.

[0114] As described above, in some embodiments, if Figure 12CAs shown, if the renegotiation request is accepted and both network A and network B determine to reconfigure the multi-USIM user equipment 102, the reconfiguration process in USIM A and USIM B can be performed simultaneously by storing the reconfiguration message of network B (step 5) (step 8). In addition, in some embodiments, if the reconfiguration process is successfully performed in both network A and network B, the multi-USIM user equipment 102 can send a reconfiguration completion message to network A and network B respectively. On the other hand, if the reconfiguration process in USIM A and / or USIM B fails, USIM A and USIM B can continue to use the configuration used before the reconfiguration process and initiate an RRC connection reestablishment process.

[0115] Additionally or alternatively, in some embodiments, network A may determine to modify its feature set. In particular, in such embodiments, network A may determine to switch from a first feature set (e.g., feature set entry 1) to a second feature set (e.g., feature set entry 2). Figure 11 The band combinations and corresponding feature sets in FIG. 5 provide example configurations of feature sets that may be switched by network A.

[0116] Additionally or alternatively, in some embodiments, the multi-USIM user equipment 102 may not simultaneously perform the reconfiguration process in USIM A and USIM B. In this example, it is assumed that network A operates in frequency band A and network B operates in frequency band B. Furthermore, the following original or initial capabilities are assumed:

[0117] Network A: Feature set A,1 {bandwidth = 40 MHz, MIMO layers = 4};

[0118] Network B: Feature set B,1 {bandwidth = 20 MHz, MIMO layers = 2}.

[0119] Furthermore, assuming updated capabilities:

[0120] Network A: Feature set A,2 {bandwidth = 80 MHz, MIMO layers = 2};

[0121] Network B: Feature set B,2 {bandwidth = 80 MHz, MIMO layers = 4}.

[0122] If the reconfiguration procedure for network B is completed but the reconfiguration procedure for network A is not performed, the UE capabilities used by network A and network B may be as follows:

[0123] Network A: Feature set A,1 {bandwidth = 40 MHz, MIMO layers = 4};

[0124] Network B: Feature set B,2 {bandwidth = 80 MHz, MIMO layers = 4};

[0125] In this case, the maximum MIMO layer may exceed the maximum value.

[0126] Additionally or alternatively, in some embodiments, if network A determines to modify its feature set, the reconfiguration process in USIMA and / or USIMB may fail. A failure may occur if at least one of USIMA or USIMB fails to successfully perform the reconfiguration process. That is, the reconfiguration process may be considered a failure if: reconfiguration of USIMA succeeds but reconfiguration of USIMB fails; reconfiguration of USIMB succeeds but reconfiguration of USIMA fails; or reconfiguration of both USIMA and USIMB fails. Figure 13 The following is a flow chart of the interactions in the event that the reconfiguration procedure fails. In step 1, the USIMA and USIMB may continue to use the configuration they used before the reconfiguration procedure. In step 2, the USIMA and USIMB may perform their respective RRC connection reestablishment procedures.

[0127] Additionally or alternatively, in some embodiments, when Network A determines to modify its BC and feature set, a BC capability renegotiation scheme may be performed. Figure 14A and Figure 14B The corresponding interaction flow chart of this BC capability renegotiation scheme is shown when network A decides to modify its BC and feature set.

[0128] refer to Figure 14A and Figure 14B In step 1, USIM A and USIM B may be in RRC connected state. In step 2, network A may determine to modify its BC and corresponding feature set. In step 3, network A may send a message to the multi-USIM user equipment 102 requesting modification of preferred parameters and / or capabilities. Figure 14A and Figure 14B As shown, the request modification message may also be a renegotiation request message, or be included in a renegotiation request message. In certain embodiments, the message may include one or more preferred frequency band combinations, preferred MIMO layer capabilities, and / or preferred power capabilities. Additionally or alternatively, network A may send the message when it determines to modify its BC and corresponding feature set. Additionally or alternatively, the message may be an RRC message or a MAC CE message.

[0129] In step 4, the multi-USIM user device 102 may determine whether to accept the modification request. Figure 14A In , the multi-USIM user equipment 102 determines to accept the modification request. Figure 14B In the case of the multi-USIM user equipment 102, the modification request is rejected. Figure 14A and Figure 14B Describe in more detail.

[0130] Specific reference Figure 14A In step 4, the multi-USIM user device 102 determines to accept the modification request. Furthermore, the multi-USIM user device 102 may determine one or more available BCs and corresponding feature sets based on the received message, network information, and UE capabilities. In step 5, the multi-USIM user device 102 may send the available BCs and corresponding feature sets to network B. In turn, network B may select a suitable BC from the received available BCs and corresponding feature sets. In addition, network B may send a reconfiguration message to the multi-USIM user device 102. In some embodiments, in step 6, the multi-USIM user device 102 may send the selected BC and corresponding feature set to network B. In step 7, network A may again send a reconfiguration message to the multi-USIM user device 102. In step 8, the multi-USIM user device 102 may perform a reconfiguration process in USIM A and USIM B. For at least some embodiments, the reconfiguration process in USIM A and USIM B may be performed at the same time (simultaneously).

[0131] Specific reference Figure 14B In some embodiments of step 4, the multi-USIM user equipment 102 may determine to reject the renegotiation request. If the multi-USIM user equipment 102 rejects the request, in step 5, the multi-USIM user equipment 102 may send a rejection indication to network A. In some embodiments, the rejection indication may be an RRC message or a MAC CE message.

[0132] Figure 14C An interactive flow chart of another BC capability renegotiation scenario is shown when network A decides to modify its BC and feature set. Figure 14C The scheme in is similar to Figure 14A and Figure 14B , except that the multi-USIM user equipment 102 does not determine whether to accept or reject the renegotiation request. Figure 14C In the solution, the multi-USIM user equipment will delegate the decision to the network b

[0133] In more detail, in Figure 14C The first three steps are similar to Figure 14A and Figure 14B That is, in step 1, USIM A and USIM B may be in RRC connected state. In step 2, network A may determine to modify its BC and corresponding feature set. In step 3, network A may send a message to the multi-USIM user equipment 102 requesting modification of preferred parameters and / or capabilities. Figure 14CAs shown, the request modification message may also be a renegotiation request message, or be included in the renegotiation request message. In step 4, the multi-USIM user device 102 determines not to accept or reject the renegotiation request. However, the multi-USIM user device 102 may determine one or more available BCs and corresponding feature sets of network B. In step 5, the multi-USIM user device 102 may send one or more available BCs and feature sets to network B. Network B may determine whether to accept or reject the request. Figure 14C As shown, when network B determines to reject the request, network B may send a rejection indication to the multi-USIM user equipment 102. In step 6, the multi-USIM user equipment 102 may send a rejection indication to network A.

[0134] Additionally or alternatively, in some embodiments, in the case where the frequency band of network B in the selected BC is not included in the UE capability filter requested by network A, the multi-USIM user equipment 102 may report an available BC that can work with the frequency band of network B (according to the first method described above) or an available BC that includes the frequency band of network B and other frequency bands (according to the second method described above). Figure 14A In the event that the reconfiguration procedure in step 8 fails, the USIMA and USIMB may continue to use the configuration used before the reconfiguration procedure and initiate an RRC connection reestablishment procedure as described above.

[0135] Figure 15A flow chart illustrating an interaction flow for a measurement negotiation scheme is shown. In step 1, a USIM connects to network A. In step 2, USIM B determines to enter an active state, and the multi-USIM user equipment 102 determines one or more available measurement configuration restrictions. In step 3, the multi-USIM user equipment 102 may send one or more available measurement configuration restrictions to network A via a message. Generally, the measurement configuration restrictions may include at least one of the following parameters: the maximum number of inter-frequency carriers that network A is permitted to configure for measurement; the maximum number of measurement identifiers that network A is permitted to perform intra-frequency and inter-frequency measurements on each serving frequency; the maximum number of sounding reference signal (SRS) resources and cross-link interference (CLI) received signal strength indicator (RSSI) resources that network A is permitted to configure; or one or more measurement gap configurations. Generally, a measurement gap configuration defines one or more parameters of a measurement gap. A measurement gap is a time period reserved by a user equipment during which the user equipment does not transmit or receive data and during which the user equipment may tune its receiver to a target frequency and / or perform one or more measurements on the target frequency. The measurement gap configuration defines one or more parameters of a measurement gap. Non-limiting example parameters of a measurement gap include a measurement gap length and a measurement gap repetition period. Other parameters defining a measurement gap are also possible. Furthermore, generally speaking, as used herein, a measurement configuration constraint is a specific value or set of values ​​for a corresponding one of the measurement configuration parameters. For example, a measurement gap configuration constraint may include a first value indicating a measurement gap length and a second value indicating a measurement gap repetition period.

[0136] In some embodiments, this message is sent when USIM A connects to network A and USIM B needs to enter an active state. Additionally or alternatively, in some embodiments, the aforementioned items, except for the measurement gap configuration, are directly determined by the multi-USIM user device 102, and the multi-USIM user device 102 reports these items to network A and network B, respectively. Additionally or alternatively, in some embodiments, the measurement gap configuration is not sent. In the case where the measurement gap types of the two networks are per frequency range 1 (FR1) and per frequency range 2 (FR2), respectively, the measurement gap configuration may not be coordinated. On the other hand, in the case where the measurement gap types of the two networks are not per FR1 and per FR2, respectively, the measurement gap configuration is coordinated. In other embodiments of these embodiments, the measurement gap configuration is determined by the multi-USIM user device 102 and network A. Specifically, in these embodiments, the multi-USIM user device 102 determines multiple available measurement gap configurations for network A. The multi-USIM user device 102 may send the multiple available measurement gap configurations in the form of a list of available measurement gap configurations. Network A then selects a suitable measurement gap configuration from the reported list of available measurement gap configurations and includes the selected suitable measurement gap configuration in a reconfiguration message. In addition, in at least some embodiments, the message is an RRC message or a MAC CE.

[0137] Figure 16 The following is an interactive flow chart illustrating a measurement negotiation scenario when measurement gap configuration is not coordinated. In step 1, USIM A connects to network A. In step 2, USIM B enters the active state, and the multi-USIM user equipment 102 determines measurement configuration restrictions. In step 3, the multi-USIM user equipment 102 sends the measurement configuration restrictions to both network A and network B, respectively, and performs a reconfiguration procedure. Furthermore, in some embodiments, to avoid exceeding the maximum UE capability, the reconfiguration procedure in USIM A precedes the reconfiguration procedure in USIM B, or the reconfiguration procedures in USIM A and USIM B are performed simultaneously.

[0138] Figure 17 The following is an interactive flow chart illustrating a measurement negotiation scenario when coordinating measurement gap configurations. In step 1, USIM A connects to network A. In step 2, USIM B determines to enter the active state, and the multi-USIM user device 102 determines available measurement configuration restrictions. In step 3, the multi-USIM user device 102 sends measurement configuration restrictions to network A, including one or more available measurement gap configurations. In steps 4 and 5, network A and USIM A perform a reconfiguration procedure based on the reported measurement configuration restrictions and the selected measurement gap configuration. In step 6, the multi-USIM user device 102 may send the measurement configuration restrictions to network B, and network B may reconfigure the multi-USIM user device 102.

[0139] Figure 18A and Figure 18B The corresponding interaction flow chart of the measurement renegotiation scheme is shown. In this scheme, network A does not modify the measurement gap configuration. In more detail, in step 1, USIM A and USIM B are in a connected state. In step 2, network A determines to modify its measurement configuration restrictions. However, network A determines not to modify the measurement gap configuration. In step 3, network A may send a modification request message with preferred parameters to the multi-USIM user equipment 102. Figure 18A As shown, the modification request message may also be a renegotiation request message, or be included in a renegotiation request message. The message may include at least one of the following: the maximum number of inter-frequency carriers that network A is permitted to configure for measurement; the maximum number of measurement identifiers allowed for network A to perform intra-frequency and inter-frequency measurements on each serving frequency; or a measurement gap configuration. Furthermore, in some embodiments, the message is an RRC message or a MAC CE.

[0140] In step 4, the multi-USIM user device 102 may determine whether to accept the renegotiation request. Figure 18A In , the multi-USIM user equipment 102 determines to accept the request. Figure 18B In the case of the multi-USIM user equipment 102, the modification request is rejected. Figure 18A and Figure 18B Describe in more detail.

[0141] Specific reference Figure 18A In step 4, if the multi-USIM user equipment 102 accepts the renegotiation request, then in step 5, the multi-USIM user equipment 102 may send updated measurement configuration limits to network A and network B, respectively. In return, network A and network B may send reconfiguration messages to USIM A and USIM B, respectively. In step 6, USIM A and USIM B may be reconfigured, for example, based on the reconfiguration messages. For at least some embodiments, USIM A and USIM B may be reconfigured simultaneously.

[0142] Specific reference Figure 18B If the multi-USIM user equipment 102 rejects the renegotiation request, the multi-USIM user equipment 102 may send a rejection indication to network A.

[0143] Figure 18C and Figure 18D FIG1 shows a corresponding interaction flow chart of another measurement renegotiation scheme. In this scheme, network A determines to modify the measurement gap configuration. Figure 18C and Figure 18D, USIM A and USIM B are in a connected state. In step 2, network A determines to modify its measurement configuration restrictions, which includes modifying the measurement gap configuration. In step 3, network A may send a modification request message with preferred parameters to the multi-USIM user equipment 102. Figure 18C As shown, the modification request message may also be a renegotiation request message, or be included in a renegotiation request message. The message may include at least one of the following: the maximum number of inter-frequency carriers that network A is allowed to configure for measurement; the maximum number of measurement identifiers allowed for network A to perform intra-frequency and inter-frequency measurements on each serving frequency; or a measurement gap configuration. In some embodiments, the message is an RRC message or a MAC CE.

[0144] In step 4, the multi-USIM user device 102 may determine whether to accept or reject the renegotiation request. In this example, the multi-USIM user device 102 accepts the renegotiation request. In addition to accepting the renegotiation request, the multi-USIM user device 102 may determine one or more available measurement configuration restrictions for network B. In step 5, the multi-USIM user device 102 may send the one or more available measurement configuration restrictions to network B. That is, in some embodiments, if network A determines to modify its measurement gap configuration, the multi-USIM user device 102 may determine the measurement configuration restrictions with one or more available measurement gap configurations and report them to network B (step 5).

[0145] In response, in step 5, Network B may determine whether to accept the renegotiation request. Figure 18C In , Network B accepts the renegotiation request. Figure 18D In this case, network B rejects the renegotiation request. These two cases will refer to Figure 18C and Figure 18D Described in further detail.

[0146] Specific reference Figure 18C If network B accepts the renegotiation request, network B may select appropriate available measurement configuration restrictions, including appropriate measurement gap configuration restrictions, for example, from a reported list of available measurement gap configurations. Network B may send the appropriate available measurement configuration restrictions to the multi-USIM user equipment 102. In step 6, the multi-USIM user equipment 102 may send the appropriate measurement configuration restrictions to network A. In step 7, network A may send a reconfiguration message to the multi-USIM user equipment 102. In step 8, USIM A and USIM B may be reconfigured, for example, based on the reconfiguration message. In at least some embodiments, USIM A and USIM B are reconfigured simultaneously.

[0147] Specific reference Figure 18DIn step 5, if network B rejects the renegotiation request, network B may send a rejection indication to the multi-USIM user equipment 102. In step 6, the multi-USIM user equipment 102 may send a rejection indication to network A.
