Abstract: Aspects described herein relate to communicating with multiple cells based on two separate subscriptions stored at the UE in a dual subscription dual standby (DSDS) mode, switching to communicate with the multiple cells in a dual subscription dual active (DSDA) mode, transmitting, to at least one of the multiple cells and based on a number of component carriers allowed for a subscription being exceeded by switching to communicate in the DSDA mode, assistance information to indicate a threshold amount of component carriers for the UE, and transmitting, to at least one of the multiple cells and based on the number of component carriers allowed for the subscription being exceeded by switching to communicate in the DSDA mode, a channel quality indicator (CQI) value for one or more cells of the multiple cells to request deactivation of one or more component carriers with, or release of, the one or more cells.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. The UE may identify a first set of bands associated with a first subscription and a second set of bands associated with a second subscription. The UE may determine that at least a first band from the first set of bands and at least a second band from the second set of bands share a same set of radio frequency (RF) front-end resources. The UE may then refrain from communicating on a third band from the first set of bands while communicating on a remaining set of bands, where the third band may be associated with a secondary component carrier (SCC) of a multi-carrier communications scheme. Refraining from communicating on the third band may be based on the first and second bands sharing the RF front-end resources and the third band being associated with the SCC.

Abstract: Apparatus, methods, and computer-readable media for facilitating managing multi-SIM concurrent mode for TDD co-banded or spectrum overlap carriers are disclosed herein. An example method for wireless communication at a user equipment (UE) includes estimating a maximum transmit power for a first subscriber based on a low-noise amplifier (LNA) input power threshold associated with an active receive chain of a second subscriber, where the UE comprises the first subscriber and the second subscriber. The example method also includes transmitting, via an active transmit chain of the first subscriber, an uplink transmission at the first subscriber maximum transmit power based on the first subscriber and the second subscriber operating concurrently, and a transmit power associated with the uplink transmission being greater than the first subscriber maximum transmit power.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, via a first subscription of the UE, a trigger event for a conditional handover of the UE from a source network entity to a target network entity. The UE may determine, based at least in part on the trigger event, that a target band associated with the target network entity is not compatible with a serving band associated with a second subscription of the UE. The UE may store the trigger event for the conditional handover in a buffer of the UE. The UE may perform an action related to the conditional handover based at least in part on a condition being satisfied. 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 receive, at a modem from an application processor, sets of values for connected mode discontinuous reception (C-DRX) configuration parameters, each of the sets of values for the C-DRX configuration parameters being associated with a corresponding one of a plurality of active applications. The UE may determine a set of selected values for the C-DRX configuration parameters based at least in part on the sets of values. The determination of the set of selected values may include identifying an extremum value for a first C-DRX configuration parameter among the sets of values and determining a selected value for the first C-DRX configuration parameter as the extremum value. The UE may transmit a request indicating the set of selected values for the C-DRX configuration parameters. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a first communication link using a first radio access technology (RAT). The UE may establish a second communication link using a second RAT. The UE may determine whether to prioritize antenna selection for the first communication link using the first RAT or the second communication link using the second RAT. The UE may prioritize antenna selection for the first communication link or the second communication link based at least in part on the determination. Numerous other aspects are provided.

Abstract: In an embodiment, a UE receives a first uplink grant for a first RAT (e.g., 5G NR) and a second uplink grant for a second RAT (e.g., LTE). In one embodiment, the UE schedules an uplink transmission on the first RAT (e.g., by selectively dropping the uplink transmission on particular resource blocks) so as to manage an amount of time that is based on concurrent uplink transmissions on both the first and second RATs are performed. In another embodiment, the UE establishes a first period of time where a BSR transmitted by the UE on the first RAT is adjusted based on scheduling of concurrent uplink multi-RAT transmissions, and a second period of time where no BSR is transmitted by the UE on the first RAT based where concurrent uplink transmissions on both the first and second RATs are not permitted to be scheduled.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a receiving device, such as a user equipment (UE), may reduce packet congestion associated with communications between the receiving device and a transmitting device, such as a server, via a radio access network (RAN). The receiving device may measure congestion metrics associated with receiving data packets from the transmitting device via the RAN. The congestion metrics may include RAN congestion metrics and transport or application layer congestion metrics associated with the network connection between the receiving device and the transmitting device. The receiving device may estimate packet congestion at the receiving device according to the measured congestion metrics. The receiving device may modify connection parameters of the network connection based on the estimated packet congestion. The receiving device may communicate with the transmitting device over the network connection in accordance with the modified connection parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a combination of a first band and a second band, whether a measurement offset is to be applied for a neighbor measurement on the second band based at least in part on an estimated impact of interference from the first band on the second band; and selectively apply the measurement offset for the neighbor measurement based at least in part on whether the measurement offset is to be applied; or selectively report the measurement offset to a base station associated with the neighbor measurement based at least in part on whether the measurement offset is to be applied. Numerous other aspects are provided.
