Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may determine a time-averaged power limit of a set of antennas. The apparatus may modify an antenna switching configuration based at least in part on the time-averaged power limit. The apparatus may transmit a signal using an antenna, from the set of antennas, associated with the modified antenna switching configuration, wherein the antenna is associated with a higher power limit than one or more other antennas. 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 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: 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: 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: Aspects of the present disclosure present techniques for coordination between a user equipment (UE) and one or more network entities to allow necessary interruptions on a first link associated with a first subscriber identification module (SIM) of the UE in order to establish or use a second link associated with a second SIM of the UE. A UE may include two or more SIMs, such as, for example, when offering Dual-SIM-Dual-Active (DSDA) functionalities. The UE may be limited by a single receiving chain, disregarding the multiple SIMs carried therein. The present disclosure alleviates or removes such limitations by coordinating between the UE and one or more network entities to optimize the use of the multiple SIMs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an antenna switch selection associated with a dual connectivity antenna configuration, wherein the antenna switch selection is associated with a first radio access technology (RAT) and the dual connectivity antenna configuration permits communication via the first RAT and a second RAT; determine, based at least in part on the antenna switching selection, a quantity of communication chains, associated with the first RAT, that are affected by an antenna switching process of the second RAT; and selectively permit, based at least in part on the quantity of communication chains, a reconfiguration of the dual connectivity antenna configuration according to the antenna switch selection. Numerous other aspects are provided.

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: Systems, methods, and apparatus are described that provide for communicating coexistence messages over a multi-drop serial bus. A method performed at a device coupled to a serial bus includes receiving first coexistence information directed to a first device coupled to the serial bus, generating a first coexistence message representative of the first coexistence information, converting the first coexistence message to obtain a first datagram including the first coexistence information, and transmitting the first datagram to the first device over the serial bus. The first coexistence message may be configured for communication through a point-to-point data link. The first datagram may be configured according to a first protocol associated with the serial bus.

Abstract: The various embodiments provide methods implemented in a multi-RF communication device for managing a victim subscription's de-sense by proactively implementing an RF coexistence management strategy on the victim subscription when an RF coexistence event starts. In various embodiments, a multi-RF communication device may implement an RF coexistence management strategy by determining when an aggressor subscription will de-sense a victim subscription and configuring the victim to anticipate and mitigate de-sense during the aggressor's transmissions. Thus, the various embodiments may provide dramatic improvements to the victim's overall reception performance and overall user experience.
