Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for a UE to determine whether to maintain or remove a radio frequency (RF) path from a set of candidate paths considered for transmit antenna switch diversity (ASDIV). The determination allows the UE to avoid signal loss or degradation in coexisting networks at similar frequency ranges. For example, ASDIV allows two or more antennas to form different input and output ports to establish different RF paths. Coexistent networks, such as wireless wide-area-network (WWAN) and wireless local-area-network (WLAN) may utilize different RF paths to optimize reliability and efficiency. The overlapping of the bands may cause signal attenuation or degradation from at least one of the networks. The present disclosure provides techniques for detecting signal attenuation at least partially caused by overlapping bands and removing an associated RF path to avoid such signal loss or attenuation.

Abstract: Methods, systems, and devices for wireless communications are described that support subscriber identification module (SIM) prioritization based on service priority and quality of service (QoS) parameters. A user equipment (UE) may identify a set of available RF components for communications at the UE that may be shared between a first SIM and a second SIM. The UE may identify multiple resource partitions of the set of available RF components, each resource partition providing resources for contemporaneous communications of both the first SIM and the second SIM. The UE may select one of the resource partitions for the contemporaneous communications based on service level priorities associated with each SIM and which resource partition provides sufficient RF resources to satisfy the QoS parameters associated a highest service level priority of the multiple SIMS.

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 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: An apparatus may operate in a dual connectivity mode in which the apparatus is simultaneously connected to carriers of different radio access technologies. The apparatus may operate via a first antenna set of a plurality of antenna sets, the first antenna set including a first communication path. The apparatus may determine to operate via a second antenna set of the plurality of antenna sets based on whether one or more criteria is satisfied. The apparatus may select at least one second communication path for the second antenna set based on the one or more criteria. The apparatus may operate via the second antenna set over the at least one second communication path when the criteria is satisfied.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify at least one collision between a periodic reporting of channel state information associated with a first radio access technology (RAT) and a periodic reference signal transmission associated with a second RAT, wherein each reference signal transmission of the periodic reference signal transmission is sequentially transmitted via a plurality of antennas based at least in part on a first antenna order. The UE may determine a second antenna order for the periodic reference signal transmission that resolves the at least one collision. The UE may transmit the periodic reference signal transmission using the second antenna order. Numerous other aspects are provided.

Abstract: The present disclosure relates to methods, devices and software that can be used for preventing damage to RF front end equipment used in wireless communication systems. In some aspects, a user equipment (UE) may establish a first communication having a first priority, wherein the first communication is associated with a first subscriber in a connected mode. The UE may establish a second communication having a second priority, wherein the second communication is associated with a second subscriber in the connected mode. The UE may identify a state of a transmit/receive (TRX) switch shared between the first communication and the second communication. The UE may perform, based at least in part on the state of the TRX switch, at least one of the first communication or the second communication using a TRX switching configuration.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a user equipment (UE). The apparatus determines that a first subscriber identity module (SIM) and a second SIM of the UE share a cross switch and determines whether to modify concurrent operation of the first SIM or the second SIM based, at least in part, on a determination that the first SIM and the second SIM of the UE share the cross-switch. The concurrent operation of the first SIM and the second SIM may include the first SIM performing SRS antenna switching and the second SIM performing an idle mode activity.
