[0019] Detailed Description The section headings are used in this document only to facilitate 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 technology may be applied to wireless systems using protocols other than 5G or 3GPP (registered trademark) protocols.

[0020] 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.

[0021] 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 processor electronics 210, such as a microprocessor, that implements one or more of the technologies presented in this document. The apparatus 205 can include transceiver electronics 215 that transmit and / or receive wireless signals via one or more communication interfaces, such as (one or more) antennas 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 electronics 210 can include at least a portion of the transceiver electronics 215. In some embodiments, at least some of the disclosed technologies, modules, or functions are implemented using the apparatus 205.

[0022] The hardware capabilities of the UE include multiple multi - 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 split among multiple SIMs. In some cases, the UE may encounter temporary hardware contention, 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, in some embodiments, can be implemented to address these issues by imposing temporary restrictions on UE capabilities using assistance (e.g., assistance information) from the UE communicating with network A.

[0023] In some implementations, a dual transmitter / receiver (Tx / Rx) MUSIM may be used. For example, the following techniques may be used to implement the MUSIM.

[0024] UE capabilities

[0025] In some embodiments, two capability bits are introduced, one for the support gap and the other for "detach connection". Different capabilities for periodic and aperiodic gaps are not required.

[0026] The MUSIM - related capabilities are per UE (without distinction between FRx and xDD).

[0027] In some implementations, the following techniques can be used.

[0028] UE Notification Regarding Network Switching for Multi-SIM

[0029] Figure 3 shows an example of UE capability transfer based on 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 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 to the UE to retrieve UE radio access capability information. 3. In response to the UE Capability Enquiry message, the UE sends a first UE Capability Information message (UEcapabilityinformation message 1) to Network A, submitting UE capability information to the network. 4. The UE starts the RRC connection setup procedure with Network B using SIM2 (e.g., sends an RRCsetuprequest message). 5. The UE detects that the UE capability information it can provide to Network A has changed due to 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 second UE Capability Information message (UEcapabilityInformation message 2) to Network A to update the UE capability information.

[0031] Figure 4 shows another example of UE capability transfer based on some embodiments of the disclosed technology.

[0032] 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 to the UE to retrieve UE radio access capability information. 3. In response to the UE capability enquiry message, the UE sends a first UE capability information message (UEcapabilityinformation message 1) to network A, submitting the UE capability information to the network. 4. The UE receives a paging message for Sim2 from network B, or the UE desires 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 capability provided to network A. 6. The UE sends a second UE capability information message (UEcapabilityInformation message 2) to network A to update the UE capability information. 7. After, before, or simultaneously with step 6 above, the UE starts the RRC connection setup procedure with network B using SIM2.

[0033] FIG. 5 shows another example of UE capability transfer according to some embodiments of the disclosed technology.

[0034] In some embodiments of the disclosed technology, UE capability transfer may include the following operations. 1. The UE has set up an RRC connection with network A using SIM1 and an RRC connection with network B using SIM2. During the procedure, the UE may send a UE capability information 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 it can provide to network A have changed. The UE sends another UE capability information message (UE capability information message 2) to network A to update the UE capability information.

[0035] FIG. 6 shows another example of UE capability transfer based on some embodiments of the disclosed technology.

[0036] Different from the current technology, new scenarios can be added to UE capability transfer. The UE can initiate a UE capability information update procedure for the network.

[0037]

Table 1-1

Table 1-2

[0038] The first and second UE capability information messages (UE capability information messages 1 and 2) can include the content of the UE capability information message under the current technology.

[0039] In some implementations, in the first UE capability information message (UE capability information message 1), ue-CapabilityRAT-Container_2 is introduced.

[0040] In some implementations, the sets of capabilities in ue-CapabilityRAT-Container_2 and ue-CapabilityRAT-Container are different.

[0041] In some implementations, the network may store the UE capabilities in two containers and may obtain one of them as the UE capabilities.

[0042] The second UE capability information message (UEcapabilityInformation message 2) may include one or more indicators to indicate which container contains the content according to the current UE capabilities.

[0043] The indicator may indicate the UE capabilities of one radio access technology (RAT) type, or may indicate the UE capabilities of all RAT types within the first UE capability information message (UEcapabilityInformation message 1).

[0044] Figure 7 shows an example of a UE capability transfer procedure of a wireless device based on some embodiments of the disclosed technology.

[0045] 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 sends a first UE capability information message (UEcapabilityInformation message 1) to the network in response to the UE capability enquiry message (UEcapabilityEnquiry message). After 4.740, while the UE maintains an RRC connection with the network, the SIM2 sets up a new RRC connection with another network (multi-SIM UE), or the UE releases the RRC connection with another network using SIM2 (multi-SIM UE), or for some other reason, if the UE desires to update the UE capability information. 5. The UE sends a second UE capability information message (UEcapabilityInformation message 2) to the network to update the UE capability information.

[0046] Figure 8 shows an example of the UE capability transfer procedure of the network based on some embodiments of the disclosed technology.

[0047] 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 first UE capability information message (UEcapabilityInformation message 1) sent in response to the UE capability enquiry message (UEcapabilityEnquiry message). 4. The network receives a second UE capability information message (UEcapabilityInformation message 2) initiated by the UE and updates the UE's capability information stored in the network.

[0048] In some implementations, UE capability information messages 1 and 2 may use the same format as the UE capability information message under the current technology.

[0049] In the above step 3, the network may receive a first UE capability information message (UEcapabilityInformation message 1), and configure / reconfigure / set up / release an RRC connection with the UE based on the capabilities of the UE within the first UE capability information message (UEcapabilityInformation message 1).

[0050] In the above step 4, the network may receive a second UE capability information message 2 (UEcapabilityInformation message 2), may update the UE capabilities based on the content in the second UE capability information message 2 (UEcapabilityInformation message 2), and may configure / reconfigure / set up / release an RRC connection with the UE based on the capabilities of the UE.

[0051] In some implementations, the first UE capability information message (UEcapabilityInformation message 1) includes a plurality of capability sets and a message2 with one or more indicators.

[0052] In the above step 3, the network may receive a first UE capability information message (UEcapabilityInformation message 1) (with a plurality of capability sets for one RAT), and configure / reconfigure / set up / release an RRC connection with the UE based on one of the plurality of capability sets within the first UE capability information message (UEcapabilityInformation message 1).

[0053] In step 4 above, the network may receive a second UE capability information message 2 (UEcapabilityInformation message 2), update the UE capability based on the indicator in the second UE capability information message 2 (UEcapabilityInformation message 2) and the set in the first UE capability information message (UE capabilityInformation message 1), and configure / reconfigure / set up / release the RRC connection with the UE based on the UE's capability.

[0054] As discussed above, if the network does not recognize a change in the radio access capability of a wireless device with which it is communicating, wireless resources may be wasted and data loss may occur. The disclosed technology may be implemented in some embodiments to address these issues by updating UE capability information using a second UE capability information message that is different from the first UE capability information message transmitted in response to a UE capability query message.

[0055] In some implementations, the UE initiates a capability transfer procedure for the network to update the UE capability information.

[0056] In some implementations, the capability information is changed by an RRC connection setup procedure with network B using SIM2.

[0057] In some implementations, a change in UE capability information causes the UE to initiate a capability transfer procedure.

[0058] In some implementations, a UE that wants to change its UE capability information for another connection with network B using a different SIM can initiate a capability transfer procedure.

[0059] In some embodiments, the UE capability transfer procedure may include the following operations. That is, 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 query message to the UE to retrieve UE radio access capability information; 3) the UE sends a UE capability information message 1 to network A in response to the query message to submit the UE capability information to the network; 4) the UE starts an RRC connection setup procedure with network B using SIM2 (e.g., sends an RRC setup request message); 5) the UE detects that the UE capability information that the UE can provide to network A has 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 capability information message 2 to network A to update the UE capability information.

[0060] In some embodiments, the UE capability transfer procedure may use a new format for the first and second UE capability information messages (UE capability Information message 1 and 2).

[0061] In some embodiments, the first UE capability information message (UE capability Information message 1) may include multiple UE capability sets for one RAT type. In addition, one or more indicators in the second UE capability information message 2 (UE capability Information message 2) can be used to indicate which set should be used.

[0064] In some implementations, process 900 may further include updating a wireless access capability between the wireless device and the first network by transmitting, by the wireless device, to the first network, a second user equipment capability information message indicating the wireless access capability between the wireless device and the first network.
