Abstract: Apparatus and methods to support parallel access to services of multiple subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs) by a wireless device are disclosed. The wireless device is a single-radio wireless device that includes wireless circuitry that supports an active voice or video connection via a single radio access network of a cellular wireless network at a time. To send or receive data for a second SIM/eSIM, when an active voice or video connection for a first SIM/eSIM uses the wireless circuitry, the single-radio wireless device can i) establish parallel, linked protocol data unit (PDU) sessions for different SIMs, ii) multiplex traffic for different SIMs over a common radio connection with SIM information embedded in protocol headers for routing by network equipment, and/or iii) use an additional dedicated bearer using a first, active SIM for each data network name (DNN) over which to route for a second, suspended SIM.

Abstract: Described is a user equipment (UE) that is connected to a network component, the user equipment and the network component configured with a carrier aggregation functionality. The UE performs a method that includes determining a primary component carrier and at least one secondary component carrier associated with the carrier aggregation functionality of the user equipment, determining a component carrier quality measurement (CQM) metric for each of the component carriers, when an uplink data packet is capable of being transmitted over the secondary component carrier, selecting one of the primary component carrier and the at least one secondary component carrier based on the CQM metrics, generating measurement data indicative of the selected component carrier to increase a probability to transmit the uplink data packet over the selected component carrier and transmitting the measurement data to the network component.

Abstract: A device and method for transmitting user equipment capability information to a network. In a first mechanism, the device and method determines the carrier aggregation (CA) combinations supported by the user equipment that are relevant to the user equipment. in a priority order to the network. The relevant CA combinations may be determined based on most recent camped bands and the neighbor bands of the most recent camped bands. In a second mechanism, the device and method orders the relevant CA combinations into a prioritized list according to which CA combination have priority based on selected priority factors. Subsequently, the user equipment broadcasts the prioritized list of CA combinations to the network.

Abstract: A user equipment (UE) is configured with operations to determine whether a network supports non-voice IP Multimedia Subsystem (IMS) services. The UE determines whether a network with which the UE is communicating supports a non-voice IP Multimedia Subsystem (IMS) service and when the network supports the non-voice IMS service, initiates an IMS Protocol Data Unit (PDU) session establishment with the network.

Abstract: A user equipment (UE) is configured to establish network connections for long-term evolution (LTE) and new radio (NR) radio access technologies (RATs) in non-standalone (NSA) E-UTRA-NR dual connectivity (ENDC) operation. The UE includes a multi-antenna array for data and signaling transmissions and receptions over the LTE and NR connections. The UE determines a most efficient antenna of the multi-antenna array for an operating frequency band of the LTE and NR connections, wherein the most efficient antenna is determined based on at least one performance factor for the UE when using the antenna compared to other antennas of the multi-antenna array, evaluates one or more factors for determining whether the LTE RAT or the NR RAT is to use the most efficient antenna and transmits uplink data on the most efficient antenna via either the LTE RAT or the NR RAT based on the evaluated factors.

Abstract: A computer readable storage medium comprising a set of instructions to operate a processor, a user equipment (UE) and an integrated circuit configured to perform operations. The operations include receiving a signal broadcast by a cell of new radio (NR) network, determining whether the cell is configured for a standalone (SA) operation for NR based on the received signal, when the cell is configured for the SA operation for NR, storing a first indication locally at the UE that the cell is configured for the SA operation for NR, when the cell is not configured for the SA operation for NR, storing a second indication locally at the UE that the cell is configured for a non-standalone (NSA) operation for NR and initiating a public land mobile network (PLMN) search procedure, wherein the PLMN search procedure includes a frequency scan based on the first indication or the second indication.
