Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect, while operating in an out-of-service (OOS) mode associated with a first network, that a second network satisfies one or more switching criteria. The UE may increase a time duration associated with a periodic network acquisition scan associated with the first network based at least in part on detecting that the second network satisfies the one or more switching criteria. The UE may switch, while operating in the OOS mode, from using the first network for connectivity to using the second network for connectivity based at least in part on detecting that the second network satisfies the one or more switching criteria. Numerous other aspects are described.

Abstract: Various aspects include methods for supporting handover of a Voice over Internet Protocol (IP) (VoIP) call, such as a Voice over Wi-Fi (VoWi-Fi) call, with a user equipment (UE). Various aspects may enable VoWi-Fi call handover from support via an evolved Packet Data Gateway (ePDG) to support via Long Term Evolution (LTE) when Voice over New Radio (NR) (VoNR) is not supported by a User Equipment (UE) computing device and/or a fifth generation (5G) standalone (SA) (5G SA) network in which the UE is located.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may support multi-subscriber identity module (SIM) operation in dual SIM dual active (DSDA) deployments. In some aspects, the UE may receive, via an antenna of the UE, a first signal associated with a first network subscription on a first receive path of the antenna and a second signal associated with a second network subscription on a second receive path of the antenna. The UE may determine a signal strength for each of the first signal and the second signal, determine a first gain for the first receive path and a gain for a low noise amplifier (LNA) coupled with the antenna based on the signal strength of the first signal, and determine a gain for the second receive path based on the signal strength of the second signal and the gain of the LNA.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a first wireless connection with a first wireless device, and a second wireless connection with the first wireless device or a second wireless device, where the first wireless connection and the second wireless connection operate in a dual connectivity mode. The UE may identify first and second energy efficiency metrics associated with the first and second wireless connections, respectively. The UE may identify one or more parameters associated with a transmit power of communications at the UE, and may compare the first energy efficiency metric and the second energy efficiency metric. The UE may then allocate a first power resource to the first wireless connection, a second power resource to the second wireless connection, or both, based on the comparison, the one or more parameters, or a combination thereof.

Abstract: This disclosure provides systems, methods and apparatuses for user equipment (UE)-side and network-side mitigation of intermodulation (IM) interference, such as IM interference associated with multi-radio access technology communications. For example, the UE or a base station may detect an IM interference condition, and may perform an IM mitigation action based on detecting the IM interference condition. The UE may reduce an uplink transmit power so that IM interference on the downlink is reduced. Various base station IM mitigation actions are provided, such as suspending scheduling on a bearer, using a scheduling pattern that avoids concurrent transmission, reducing a maximum transmit power of an uplink grant of the UE, allocating resource blocks or bandwidth parts that do not overlap with an IM interference resource, changing a secondary cell group channel to a non-interfering channel, releasing a secondary cell group channel, deactivating a carrier, or changing a channel of the UE.

Abstract: Methods, systems and devices for wireless communications are described for differentiation between standalone (SA) and non-standalone (NSA) cells in a wireless communications system. A user equipment (UE) may receive an indication of a subcarrier offset for a system information block (SIB). The SIB may be for a cell of a wireless communications network. The cell may be in accordance with a radio access technology. The UE may determine, based on the subcarrier offset for the SIB, whether the cell is configured as an SA cell or as an NSA cell for the radio access technology. The UE may communicate via the wireless communications network based on whether the cell is configured as an SA cell or as an NSA cell.
