Abstract: The various embodiments include methods for managing how a DSDS mobile communication device that is accessing an arbitrary combination of any two mobile telephony networks processes paging collisions. The embodiment methods promote the control of the paging block rates for two distinct subscriptions, in which a subscription's paging block rate is the long-term percentage of its blocked paging messages over its total number of received paging messages. In the various embodiments, a mobile communication device may use a paging blocking bias to achieve a particular paging blocking rate. The paging blocking bias may be set or adjusted through various means to cause a first subscription to have a paging blocking rate that is less than, equal to, or greater than a paging blocking rate for a second subscription.

Abstract: Methods, systems, and devices are described for identifying and mitigating in-device coexistence interference for multicarrier systems implementing soft combining decoding techniques. In some aspects, the described techniques include identifying time-frequency resources of a received signal subject to coexistence interference at a transceiver of a wireless device. The time-frequency resources may include, for example, symbols, slots, code-blocks, sub-frames, subcarriers, etc. Resource-specific mitigation may then be applied to the identified resources, for example, including skipping or nulling the interfered resources in the time domain, frequency domain, or both. In some aspects, the resource-specific mitigation may be performed at the soft-combining stage of the decoding process, such as by skipping or nulling one or more log likelihood ratio (LLR) instances that correspond to the interfered resource(s).

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: 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.
