Abstract: Methods and apparatus for using an unlicensed radio frequency band component carrier for uplink transmission are disclosed. A wireless communication device receives a carrier aggregation configuration, which can include at least one licensed radio frequency band component carrier and at least one unlicensed radio frequency band component carrier. The wireless communication device establishes a set of radio bearers and associates an unlicensed radio frequency band permission level with each of the radio bearers. The wireless communication device multiplexes uplink traffic for the radio bearers on the at least one licensed radio frequency band component carrier and the at least one unlicensed radio frequency band component carrier based at least in part on the unlicensed radio frequency band permission levels associated with the radio bearers.

Abstract: A user equipment (UE) includes first and second subscriber identity modules (SIMs), possibly subscribed to different carriers. When the first SIM is in a connected state and the second SIM is in an idle state, the UE may need to periodically tune away a radio from a first frequency used for communication under the first SIM to a second frequency used for idle mode activity under the second SIM. The UE may provide to the network of the first SIM the second SIMs traffic activity pattern and/or serving frequency so that the network may provide coordinated configuration and/or scheduling for the UE device, e.g., in order to make the action of tuning away (and tuning back) the radio more efficient and/or to decrease the network impact of such radio tune aways (e.g., to decrease wasted uplink scheduling and wasted downlink transmissions for the first SIM).

Abstract: Apparatuses, systems, and methods for revocation and/or modification of user consent in Edge Computing (MEC). A user equipment device (UE) may determine that user consent needs to be updated. The user consent may be associated with MEC. Additionally, the UE may transmit, via an application layer of the UE, a user consent modification request to an edge application server of a network, e.g., of an edge data network. The user consent modification request may be carried in application data traffic. The user consent modification request may be indicated via an Nnef_ParameterProvision_Update service operation. The user consent modification request is indicated via an Nnef_ParameterProvision_Update service operation.

Abstract: Apparatuses, systems, and methods for generating and utilizing improved initialization vectors (IVs) when performing encryption and authentication in wireless communications. In some scenarios, a wireless communication device may generate one or more pseudorandom multi-bit values, e.g., using a respective plurality of key derivation functions (KDFs). A first portion of each value may be used as a respective key for encryption or authentication of traffic on the user plane or the control plane. A second portion of each value may be used as a nonce value in a respective IV for use with a respective key for encryption or authentication of traffic on the user plane or the control plane. In some scenarios, the nonce values may instead be generated as part of an additional pseudorandom value (e.g., by executing an additional KDF), from which all of the IVs may be drawn.

Abstract: A device, system, and method performs a Voice over Long Term Evolution (LTE) (VoLTE) call setup procedure. The device includes a transceiver establishing a connection with a LTE network and an Internet Protocol (IP) Multimedia Subsystem (IMS). The device includes a processor executing a VoLTE call application with a further user equipment, receiving an input to execute the VoLTE call application, and generating a data packet including an indication to trigger a dedicated bearer establishment procedure. The transceiver transmits the data packet to one of the LTE network and the IMS. The indication triggers the dedicated bearer establishment procedure to be performed during a Session Initiation Protocol (SIP) signal exchange procedure.

Abstract: Apparatuses, systems, and methods to perform attachment of a wireless device to a next generation gateway via either a base station of a next generation radio access network (RAN) or a mobility management entity of a legacy RAN. An apparatus may be configured to receive an attachment request from a wireless device, determine authentication information via communication with a home subscriber server, determine, based at least in part on the authentication information, whether the wireless device is capable of communicating via the next generation RAT, and send, in response to determining the wireless device is capable, a connection request to a gateway of the next generation RAN. The authentication information may include subscription information associated with the wireless device.
