Best Mode for Carrying Out the Invention

[0020] (Detailed Description) The section headings in this document are used only for ease of understanding and do not limit the scope of the embodiments to the sections in which they are described. Furthermore, although the embodiments are described with reference to examples of 5G, the disclosed techniques may be applied to wireless systems using protocols other than 5G or 3GPP (registered trademark) protocols.

[0021] FIG. 1 shows an example of a wireless communication system (e.g., a Long-Term Evolution (LTE), 5G, or NR cellular network) including a BS120 and one or more user equipment (UE) 111, 112, and 113. In some embodiments, the uplink transmissions (131, 132, 133) can include uplink control information (UCI), upper layer signaling (e.g., UE assistance information or UE capabilities), or uplink information. In some embodiments, the downlink transmissions (141, 142, 143) can include DCI or upper layer signaling or downlink information. The UE can be, for example, a smartphone, a tablet, a mobile computer, a machine-to-machine (M2M) device, a terminal, a mobile device, an Internet of Things (IoT) device, etc.

[0022] FIG. 2 is a block diagram representation of a portion of an apparatus according to some embodiments of the disclosed technology. An apparatus 205, such as a network device or a base station or a wireless device (or UE), can include a processor electronic circuit 210, such as a microprocessor, that implements one or more of the techniques presented in this document. The apparatus 205 can include a transceiver electronic circuit 215 that transmits and / or receives wireless signals via one or more communication interfaces, such as antenna(s) 220. The apparatus 205 can include other communication interfaces for transmitting and receiving data. The apparatus 205 can include one or more memories (not explicitly shown) configured to store information such as data and / or instructions. In some implementations, the processor electronic circuit 210 can include at least a portion of the transceiver electronic circuit 215. In some embodiments, at least some of the disclosed techniques, modules, or functions are implemented using the apparatus 205.

[0023] The hardware capabilities of the UE include multiple Universal Subscriber Identity Modules (MUSIMs) shared by multiple SIMs. To use the UE's hardware capabilities efficiently and economically, the hardware capabilities need to be dynamically divided among multiple SIMs. In some cases, the UE may encounter temporary hardware conflicts, which may require the UE to release some resources (e.g., SCell / SCG) from one of the SIMs. For example, when SIM A of the UE is in the Radio Resource Control (RRC) connected state in Network A and SIM B of the UE is in the RRC idle state or RRC inactive state in Network B, two Radio Frequency (RF) chains are occupied by SIM A for communication in Network A. When SIM B of the UE enters the RRC connected state, one of the RF chains needs to be switched to SIM B. In this case, if Network A does not recognize the reduced capabilities of the UE in the RF chain, there may be data loss and waste of radio resources due to demodulation failures in Network A. The disclosed technology can be implemented in some embodiments to address these issues by imposing temporary restrictions on UE capabilities using assistance (e.g., assistance information) from the UE communicating with Network A.

[0024] In some implementations, a dual Transmitter / Receiver (Tx / Rx) MUSIM can be used. For example, the following techniques can be used to implement the MUSIM.

[0025] Figure 3 shows an example of UE capability transfer based on some embodiments of the disclosed technology.

[0026] In some embodiments of the disclosed technology, UE capability transfer may include the following operations. 1. The UE has two USIMs (Sim1 and Sim2), and the UE sets up an RRC connection with Network A using SIM1. 2. Network A sends a UE capability enquiry message (UECapabilityEnquiry message) to the UE to retrieve UE radio access capability information. 3. The UE sends a UE capability information message (UEcapabilityinformation message) to Network A in response to the UE capability enquiry message (UECapabilityEnquiry message), submitting the UE capability information to the network. 4. The UE uses SIM2 to initiate the RRC connection setup procedure with Network B (e.g., send an RRCsetuprequest message). 5. The UE detects that the UE capability information that the UE can provide to Network A has been changed for the RRC connection with Network B. The connection with Network B occupies one or more TX / RX, and as a result, the UE radio access capability that the UE can provide to Network A changes. 6. The UE sends a UE assistance information message (UEAssistanceInformation message) to Network A to update the UE capability information.

[0027] Figure 4 shows another example of UE capability transfer based on some embodiments of the disclosed technology.

[0028] In some embodiments of the disclosed technology, UE capability transfer may include the following operations. 1. The UE has two USIMs (Sim1 and Sim2), and the UE uses SIM1 to set up an RRC connection with Network A. 2. Network A sends a UE capability enquiry message (UECapabilityEnquiry message) to the UE to retrieve UE radio access capability information. 3. The UE sends a UE capability information message (UEcapabilityinformation message) to Network A in response to the UE capability enquiry message (UECapabilityEnquiry message), submitting the UE capability information to the network. 4. The UE receives a paging message for Sim2 from Network B, or the UE attempts to set up an RRC connection with Network B using SIM2. 5. To set up an RRC connection with Network B, the UE uses or transfers at least one TX / RX for Network B. Thus, the UE attempts to change or update the UE capabilities provided to Network A. 6. The UE sends a UE assistance information message (UEAssistanceInformation message) to Network A to update the UE capability information. 7. After, before, or at the same time as step 6 above, the UE starts the RRC connection setup procedure with Network B using SIM2.

[0029] Figure 5 shows another example of UE capability transfer according to some embodiments of the disclosed technology.

[0030] In some embodiments of the disclosed technology, UE capability transfer may include the following operations. 1. The UE is setting up an RRC connection with Network A using SIM1 and with Network B using SIM2. During the procedure, the UE may send a UE capability information message (UEcapabilityinformation message) to Network A and / or Network B according to the procedure shown in FIG. 3 or FIG. 4. 2. The UE releases the RRC connection with Network B, and the associated TX / RX resources are released. 3. The UE detects that the UE capabilities that the UE can provide to Network A have changed. The UE sends a UE assistance information message (UEAssistanceInformation message) to Network A to update the UE capability information.

[0032] In some implementations, the UE assistance information (UEAssistanceInformation) includes UE capability information (UECapabilityInformation) for updating UE capability information in the network.

[0033] Alternatively, the UE assistance information (UEAssistanceInformation) includes a UE capability information indicator (UECapabilityInformationindicator) for updating the UE capability information indicator in the network.

[0036] Alternatively, in the case of the UE Capability Information Indicator within the UE Assistance Information Message (UEAssistanceInformation Message), the network updates the UE capabilities according to the indicators and UE capability sets within the UE Assistance Information Message (UEAssistanceInformation Message). In some implementations, multiple sets can be used for one Radio Access Technology (RAT) type.

[0038] In the UE Capability Information Message (UECapabilityInformation Message), ue-CapabilityRAT-Container_2 may be introduced.

[0039] The capabilities set for ue-CapabilityRAT-Container_2 and ue-CapabilityRAT-Container are different.

[0040] The network stores the UE capabilities in two containers and regards one of them as the UE's capabilities.

[0041] Figure 6 shows an example of the UE capability transfer procedure of a wireless device based on some embodiments of the disclosed technology.

[0042] In some embodiments of the disclosed technology, the UE capability transfer may include the following operations. 1. The UE sets up an RRC connection with the network. 2. The UE receives a UE capability enquiry message (UEcapabilityEnquiry message) from the network. 3. The UE transmits a UE capability information message (UEcapabilityInformation message) to the network in response to the UE capability enquiry message (UEcapabilityEnquiry message). 4. After 840, when the UE attempts to update its UE capability information while maintaining an RRC connection with the network, for the purpose of setting up a new RRC connection with another network for SIM2 (multi-SIM UE), or releasing the RRC connection with another network using SIM2 (multi-SIM UE), or for any other reason. 5. The UE transmits UE assistance information (UEAssistanceInformation) to the network to update the UE capability information.

[0043] Scenario 1:

[0044] At 830, the UE transmits a UE capability information message (UEcapabilityInformation message) having only one UE capability set (under current technology, for example) to the network.

[0045] At 850, the UE transmits UE assistance information (UEAssistanceInformation) to the network. The UE assistance information (UEAssistanceInformation) includes a "UECapabilityInformation" IE and notifies the network to update the UE capability according to the UECapabilityInformation IE.

[0046] After 850, the UE sends a UE assistance information message (UEAssistanceInformation message) to the network. The UE assistance information (UEAssistanceInformation) includes a UE capability information indicator ("UECapabilityInformationindicator") IE and notifies the network to update the UE capabilities according to the indicator and the UE capability information in the UE capability information message (UEcapabilityInformation message) at 830.

[0047] Scenario 2:

[0048] At 830, the UE sends a UE capability information message (UEcapabilityInformation message) with multiple UE capability sets for RAT types to the network and notifies the network to use one (e.g., set1) of the multiple UE capability sets for one or more RAT types in the UE capability information message (UEcapabilityInformation message).

[0049] At 850, the UE sends a UE assistance information message (UEAssistanceInformation message) to the network. The UE assistance information (UEAssistanceInformation) includes a UE capability information indicator ("UECapabilityInformationindicator") IE and notifies the network to update the UE capabilities according to the UE capability information indicator ("UECapabilityInformationindicator") IE. For example, the UE uses one (e.g., set2) of the multiple UE capability sets for one or more RAT types in the UE capability information message (UEcapabilityInformation message) received at 840.

[0050] After 850, the UE sends a UE assistance information message (UEAssistanceInformation message) to the network. The UE assistance information (UEAssistanceInformation) includes a UE capability information indicator ("UECapabilityInformationindicator") IE, and notifies the network to update the UE capability according to the indicator and the UE capability information indicator. For example, some of the operations can be repeated, and set1 can be reused again.

[0051] Figure 7 shows an example of the UE capability transfer procedure of the network based on some embodiments of the disclosed technology.

[0052] In some embodiments of the disclosed technology, the UE capability transfer may include the following operations. 1. The network sets up an RRC connection with the UE. 2. The network sends a UE capability enquiry message (UEcapabilityEnquiry message) to the UE. 3. The network receives a UE capability information message (UEcapabilityInformation message) sent in response to the UE capability enquiry message (UEcapabilityEnquiry message). 4. The network receives a UE assistance information message (UEAssistanceInformation message) initiated by the UE and updates the UE's capability information stored in the network.

[0053] Scenario 1:

[0054] At 930, the network receives a UE capability information message (UEcapabilityInformation message) having only one UE capability set (e.g., under the current technology) in the network.

[0055] At 940, the network receives a UE assistance information message (UE Assistance Information message). The UE assistance information (UE Assistance Information) includes a UE capability information (UECapabilityInformation) IE, and the network updates the UE capabilities according to the UE capability information (UECAPabilityInformation) IE.

[0056] After 940, the network receives a UE assistance information message (UE Assistance Information message). The UE assistance information (UE Assistance Information) includes a UE capability information indicator (UECapabilityInformationindicator) IE, and the network updates the UE capabilities according to the indicator and the UE capability information within the UE capability information message (UEcapabilityInformation message) received at 930.

[0057] Scenario 2:

[0058] At 930, the network receives a UE capability information message (UEcapabilityInformation message) having two or more UE capability sets for RAT types to the network, and notifies the network to use one (e.g., set1) of the multiple UE capability sets for one or more RAT types within the UE capability information message (UEcapabilityInformation message).

[0059] At 940, the network receives a UE Assistance Information message. The UE Assistance Information includes a UE Capability Information indicator (UECapabilityInformationindicator) IE, and the network updates the UE capabilities according to the UE Capability Information indicator (UECapabilityInformationindicator) IE. For example, the network uses set2 for one or more RAT types within the UE capability information message (UEcapabilityInformation message) received at 940.

[0060] After 940, the network receives a UE Assistance Information message. The UE Assistance Information includes a UE Capability Information indicator (UECapabilityInformationindicator) IE, and the network updates the UE capabilities according to the indicator and the UE Capability Information indicator (UECapabilityInformationindicator). For example, some of the operations can be repeated and set1 can be used again.

[0061] As discussed above, if the network does not recognize a change in the radio access capabilities of a wireless device with which it is communicating, wireless resources may be wasted and data loss may occur. The disclosed techniques can be implemented in some embodiments to address these issues by updating UE capability information using UE assistance information provided by the UE.

[0062] In some implementations, the UE transmits to the network a UE assistance information message including UE capability information for updating the UE's capabilities, such as radio access capabilities, and the UE includes a plurality of SIMs (e.g., MUSIM), and connection to the network or disconnection from the network by a particular SIM results in a change in the radio access capabilities of another SIM communicating with another network.

[0063] In some implementations, the UE assistance information message includes a "UE capability information" or "UE capability information indicator" for notifying the network to update the UE's capability information.

[0064] The UE capability information message includes a plurality of sets / containers for one RAT type. Additionally, the indicator within the UE assistance information can be used to indicate which of the plurality of sets / containers should be used.

[0065] In some implementations, the procedures for the UE and the network can include the following operations. The UE sets up an RRC connection with the network; the UE receives a UE capability query message from the network; the UE transmits a UE capability information message to the network in response to the query message; while the UE is maintaining an RRC connection with the network, for example, because SIM2 has set up a new RRC connection with another network (multi-SIM UE scenario), or because the RRC connection with another network using SIM2 has been released (multi-SIM UE), or for any other reason, if the UE attempts to update the UE capability information; the UE transmits UE assistance information to the network to update the UE capability information.

[0066] In one scenario, a UE that has sent a UE capability information message with only one UE capability set (under the current technology) to the network can send a UE assistance information message to the network. In some implementations, the UE assistance information includes a UE capability information IE and notifies the network to update the UE capabilities according to the UE capability information IE. After these operations, the UE sends a UE assistance information message to the network. The UE assistance information includes a UE capability information indicator IE and notifies the network to update the UE capabilities according to the indicator and the UE capability information in the UE capability information message.

[0067] In another scenario, a UE that has sent a UE capability information message including multiple UE capability sets for a RAT type can notify the network to use at least one (e.g., set1) of the multiple UE capability sets for one or more RAT types in the UE capability information message. The UE sends a UE assistance information message to the network. In some implementations, the UE assistance information includes a UE capability information indicator IE and notifies the network to update the UE capabilities according to the UE capability information indicator IE. For example, at least one (e.g., set2) of the multiple UE capability sets can be used for one or more RAT types in the UE capability information message. After these operations, the UE sends a UE assistance information message to the network. In some implementations, the UE assistance information includes a UE capability information indicator IE and notifies the network to update the UE capabilities according to the indicator and the UE capability information indicator. For example, some of the operations can be repeated and set1 can be used again.

[0076] In one example, the process for wireless communication involves the first network sending a capability inquiry message associated with a first communication connection with a first subscriber identification module of the wireless device to the wireless device, the first network receiving a capability information message sent from the wireless device in response to the capability inquiry message, where the capability information message indicates the wireless access capability between the wireless device and the first network, the first network receiving an assistance information message sent from the wireless device to update the wireless access capability between the wireless device and the first network, and the first network updating the wireless access capability between the wireless device and the first network based on the capability information message and the assistance information message. This may be included.

[0077] In some implementations, the wireless device includes multiple SIMs. For example, the multiple SIMs include a first subscriber identification module (e.g., SIM1) and a second first subscriber identification module (e.g., SIM2), where SIM1 is used to communicate with the first network and SIM2 is used to communicate with the second network.

[0078] In some implementations, the capability information message may include the UE capability information message (UECapabilityInformation message) discussed above.

[0079] In some implementations, the user equipment assistance information message may include the UE assistance information message (UEAssistanceInformation message) discussed above.
