This patent document is directed generally to wireless communications.
Mobile communication technologies are moving the world toward an increasingly connected and networked society. The rapid growth of mobile communications and advances in technology have led to greater demand for capacity and connectivity. Other aspects, such as energy consumption, device cost, spectral efficiency, and latency are also important to meeting the needs of various communication scenarios. Various techniques, including new ways to provide higher quality of service, longer battery life, and improved performance are being discussed.
This patent document describes, among other things, techniques for updating user equipment capability information.
In one aspect, a method of data communication is disclosed. The method includes transmitting, by a wireless device, to a first network in a first communication connection with the wireless device, a user equipment assistance information message to update a radio access capability between the wireless device and the first network due to detecting a change in the radio access capability between the wireless device and the first network based on an establishment of a second communication connection between the wireless device and a second network; or based on a determination by the wireless device to update the radio access capability between the wireless device and the first network.
In another aspect, a method of data communication is disclosed. The method includes transmitting, by a wireless device, to a first network, a user equipment assistance information message to update a first radio access capability between the wireless device and the first network based on releasing a second communication connection between the wireless device and a second network.
In another aspect, a method of data communication is disclosed. The method includes receiving, by a first network, a user equipment assistance information message that is transmitted from the wireless device to update a radio access capability between the wireless device and the first network.
In another example aspect, a wireless communication apparatus comprising a processor configured to implement an above-described method is disclosed.
In another example aspect, a computer storage medium having code for implementing an above-described method stored thereon is disclosed.
These, and other, aspects are described in the present document.
Section headings are used in the present document only for ease of understanding and do not limit scope of the embodiments to the section in which they are described. Furthermore, while embodiments are described with reference to 5G examples, the disclosed techniques may be applied to wireless systems that use protocols other than 5G or 3GPP protocols.
The hardware capabilities of UE include multiple universal subscriber identity modules (MUSIM) that are shared by a plurality of SIMs. In order to use the hardware capabilities of UE efficiently and economically, the hardware capabilities need to be dynamically split between the multiple SIMs. In some cases, UE can experience a temporary hardware conflict, which may require UE to release some resources (e.g., SCell/SCG) from one of the SIMs. For example, when SIM A of a UE is in a Radio Resource Control (RRC) connected state in Network A while SIM B of the UE is in an RRC idle state or RRC inactive state in Network B, the two radio frequency (RF) chains will be occupied by the SIM A for the communication in Network A. Once the UE's SIM B enters an RRC connected state, one of the RF chains needs to be switched to SIM B. In this case, if Network A is not aware of the UE's reduced capability in RF chain, there may be data loss due to demodulation failures and wasting radio resources in Network A. The disclosed technology can be implemented in some embodiments to address these issues by imposing temporary restrictions on the UE capability using assistance (e.g., assistance information) from the UE in communication with Network A.
In some implementations, dual transmitter/receiver (Tx/Rx) MUSIM can be used. For example, the following techniques can be employed to implement MUSIM.

For example, the UE uses one of the plurality of UE capability sets (e.g., set2) for one or more rat-types in the UE capability information message (UEcapabilityInformation message) received at 840.
After 850, the UE sends UE assistance information message ((UEAssistanceInformation message) to the network. The UE assistance information (UEAssistanceInformation) includes UE capability information indicator (“UECapabilityInformationindicator”) 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 sea can be used again.
As discussed above, if a network is not aware of changes in the radio access capability of a wireless device in communication with the network, radio resources can be wasted, and data loss can occur. The disclosed technology can be implemented in some embodiments to address these issues by updating UE capability information using UE assistance information provided by UE.
In some implementations, the UE transmits, to the network, UE assistance information message that includes UE capability information to update the UE's capability such as radio access capability where the UE includes a plurality of SIMs (e.g., MUSIM) and connection to or disconnection from a network by a certain SIM results in changes to the radio access capability of another SIM that is in communication with another network.
In some implementations, the UE assistance information message include “UE capabilities information” or “UE capabilities information indicator” to notify the network to update the UE's capability information.
The UE capability information message includes a plurality of sets/containers for one rat-type. In addition, the indicator in the UE assistance information can be used to indicate which one of the plurality of sets/containers should be used.
In some implementations, the procedure for the UE and the network can include the following operations: UE sets up RRC connection with a network; UE receives UE capability enquiry message from the network; UE sends UE capability information message to the network in response to the enquiry message; while UE keeps the RRC connection with the network, if the UE wants to update the UE capability information, e.g., because SIM2 has set up a new RRC connection with another network (e.g., multi-sim UE scenario), or has released RRC connection with another network using SIM2 (multi-sim UE), or any other reasons; the UE transmits UE assistance information to the network to update UE capability information.
In one scenario, a UE, which has transmitted UE capability information message with only one UE capability set (under the current technology) to the network, can transmit UE assistance information message to the network. In some implementations, the UE assistance information includes UE capability information IE, and notifies the network to update the UE capabilities according to UE capability information IE. After these operations, the UE transmits UE assistance information message to the network. The UE assistance information includes UE capability information indicator IE, and notifies the network to update the UE capabilities according to the indicator and UE capability information in the UE capability information message.
In another scenario, a UE, which has transmitted UE capability information message that includes a plurality of UE capability sets for a rat-type to the network, can notify the network to use at least one of the plurality of UE capability sets (e.g., set1) for one or more rat-types in the UE capability information message. The UE transmits UE assistance information message to the network. In some implementations, the UE assistance information includes UE capability information indicator IEs, and notifies the network to update the UE capabilities according to UE capability information indicator IE. For example, at least one of the plurality of UE capability sets (e.g., set2) can be used for one or more rat-types in the UE capability information message. After these operations, the UE transmits UE assistance information message to the network. In some implementations, the UE assistance information includes UE capability information indicator IE, and notifies the network to update the UE capabilities according to the indicator and UE capability information indicator. For example, some of the operations can be repeated, and sea can be used again.
