Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, by a first subscription of the UE, a connection to a first network entity using two transmit (Tx) chains of the UE. The UE may receive, by a second subscription of the UE, a paging message from a second network entity. The UE may receive, by the first subscription from the second subscription, a request for the first subscription to enter a mode that supports one Tx chain. The UE, by the first subscription, may reduce the two Tx chains to the one Tx chain for the first subscription. The UE may perform, by the second subscription to the second network entity, the connection setup based at least in part on the first subscription reducing the two Tx chains to the one Tx chain. Numerous other aspects are described.

Abstract: Aspects are provided which allow a UE including an application processor and a modem to disable measurements of reference signals from 5G base stations which are inapplicable to EN-DC. The UE may receive a reference signal from a base station. The UE may identify a frequency range. The UE may provide, using the application processor, an indication to the modem. The UE may determine whether to measure the reference signal using the modem based on the indication provided to the modem from the application processor and whether the reference signal is within the identified frequency range and further based on whether the base station is standalone or non-standalone. The UE may refrain from measuring the reference signal in response to the determination. As a result, inter-RAT handovers from LTE base stations to 5G base stations are prevented, UE power consumption is thereby saved, and support for EN-DC is maintained.

Abstract: A method for scanning for wireless systems is described. The method includes camping on a first system of a first system type. The method also includes maintaining a second system type not available list. The method additionally includes maintaining a second system type available list. The method further includes detecting a scan trigger. The method also includes determining whether the first system is in the second system type not available list. The method additionally includes scanning for second system type systems based on a timer.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station associated with a first radio access technology (RAT), a neighbor cell list including entries for at least a first set of neighbor cells and a second set of neighbor cells, the first set of neighbor cells and the second set of neighbor cells associated with a second RAT. The UE may determine that the first set of neighbor cells is associated with a first network operator and that the second set of neighbor cells is associated with a second network operator. The UE may measure at least one neighbor cell of the neighbor cell list based at least in part on prioritization of the first set of neighbor cells relative to the second set of neighbor cells. Numerous other aspects are described.

Abstract: A UE may transmit to a base station, and the base station may receive from the UE, via an RRC message, an IDC interference indication. The IDC interference indication may be associated with at least one victim reception or at least one aggressor transmission. The IDC interference indication may include at least one of a first frequency range associated with the at least one victim reception, information associated with the at least one aggressor transmission, a first requested BWP associated with the at least one victim reception, or a second requested BWP associated with the at least one aggressor transmission. The base station may identify at least one interference mitigation measure based on the IDC interference indication. The UE and the base station may communicate based on the at least one interference mitigation measure.

Abstract: Aspects are provided which allow a UE to disable measurements of reference signals from 5G base stations which are inapplicable to EN-DC. The UE may receive a reference signal from a base station. The UE may identify a frequency range. The UE may determine whether to measure the reference signal based on whether the reference signal is within the identified frequency range. The UE may refrain from measuring the reference signal in response to the determination. The UE may also refrain from measuring the reference signal in response to a SIB received at the UE not including a ULI, or in response to a frequency associated with the reference signal not being in a list of supported bands for EN-DC. As a result, inter-RAT handovers from LTE base stations to 5G base stations are prevented, UE power consumption is thereby saved, and support for EN-DC is maintained.
