Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, while the UE is in an active session using a first radio access technology (RAT) associated with a first subscription of the UE, a call request via the first RAT, wherein the call request is associated with a second subscription of the UE. The UE may determine that the call request is received from a serving cell that is associated with fallback from the first RAT to a second RAT for calls. The UE may reject the call request or transition the second subscription to a third RAT based at least in part on the determination that the call request is received via the serving cell that is associated with fallback from the first RAT to the second RAT for calls. Numerous other aspects are described.
Abstract:
Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method generally includes receiving a measurement configuration, wherein the measurement configuration indicates at least one or more frequency bands, determining, based on one or more parameters, a periodicity for measuring the at least one or more frequency bands, and performing measurements of the at least one or more frequency bands according to the determined periodicity.
Abstract:
Certain aspects of the present disclosure relate to methods and apparatus for transmission restriction. An exemplary method generally includes initiating a mobile originating (MO) call, determining availability of parameters for a first access gating mechanism for determining whether to bar or allow transmission of the MO call, selecting the first access gating mechanism or a second access gating mechanism, based on the determination of the availability of the parameters, and applying the selected gating mechanism to determine whether to bar or allow the MO call.
Abstract:
Techniques for reading and caching system information of non-serving systems in order to shorten call setup delay are described. A user equipment (UE) may communicate with a serving system, e.g., in an idle mode or a connected mode. The UE may periodically read system information of at least one non-serving system, e.g., as a background task. The UE may cache (i.e., store) the system information of the at least one non-serving system at the UE. The UE may thereafter access a particular non-serving system among the at least one non-serving system based on access parameters in the cached system information. By caching the system information, the UE can avoid reading the system information of the particular non-serving system at the time of system access, which may then reduce call setup delay.
Abstract:
Aspects describe modifying a service search pattern based on whether a device battery is being charged (504) or is not being charged (504) (e.g., is connected to a battery charger or not connected to a battery charger). A power conservative search pattern can be utilized (508) if the battery is not being charged. If the battery is being charged, the search pattern can be an aggressive search pattern (506). Further, the search pattern can change if there is a change in whether the battery is being charged (706). The rate of charging the battery, a current battery level, amount of power consumed during the search, and/or the power being input by the battery chargers can be utilized to select and/or modify a network search pattern. Further, a user can select or change a search pattern through interaction with a user interface.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, via a first subscriber service, at least one protocol data unit (PDU) session. The UE may receive a first internet protocol (IP) address associated with the first subscriber service. The UE may register the first subscriber service with an IP multimedia subsystem (IMS) network using the first IP address. The UE may register a second subscriber service with the IMS network using a second IP address, wherein the second subscriber service uses the at least one PDU session of the first subscriber service. Numerous other aspects are described.
Abstract:
A user equipment (UE) may simulate transmissions received from a BS to perform on-device testing of the UE. For example, the UE may be configured to loopback uplink data from the UL data path and input the uplink data as simulated downlink data for processing in the DL data path. The uplink data may include data related to a video call or network diagnostics. The user application data generated by the application and proceeding through the UL data path may be used to validate the DL data path. Downlink control information (DCI) may be determined by the UE and provided to the DL data path to accompany the uplink data. The DCI may include simulated uplink grants and/or simulated downlink scheduling assignments. The simulated downlink scheduling assignments may be determined based on availability of the uplink data in the UE's memory.
Abstract:
Techniques are provided for selecting cellular and satellite networks. An example method for switching between communication networks includes receiving one or more signals via a first wireless communication network with a mobile device, determining a second wireless communication network is available based at least in part on a location of the mobile device and a time, detaching the mobile device from the first wireless communication network at the time if the second wireless communication network is available, and receiving one or more signals from the second wireless communication network with the mobile device after the time.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may allocate a first amount of power to one or more radios for a time window based on radio frequency (RF) exposure information and one or more other criteria. The UE may allocate a second amount of power to a selected channel or communication utilized by at least one radio of the one or more radios for one or more time frames within the time window based on the first amount of power allocated to the at least one radio for the time window. The UE may transmit the selected channel or communication based on the first amount of power or the second amount of power. Numerous other aspects are described.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate via a first connection using one or more transmit parameters. The UE may determine to suspend subsequent attempts to communicate via a second connection, in a dual connection mode, based at least in part on satisfaction of a threshold number of failed attempts to communicate via the second connection. The UE may determine one or more parameters for suspension of the subsequent attempts to communicate via the second connection based at least in part on a determination that satisfaction of the threshold number of failed attempts is associated with one or more exposure conditions that are based at least in part on the one or more transmit parameters. Numerous other aspects are provided.
