Abstract: Methods, systems, and devices for wireless communication are described. The method may include a user equipment (UE) tuning a first antenna panel to a first frequency band associated with a first radio access technology (RAT) and tuning a second antenna panel to a second frequency band associated with a second RAT. Further, the method may include monitoring a traffic level of communications via the first frequency band associated with the first RAT and selecting a third antenna panel for communications via the second frequency band based on the traffic level and an isolation level between the first antenna panel and the second antenna panel.

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: 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: A method, an apparatus, a transmitter component, and a computer program product for wireless communication are provided. The transmitter component may determine whether first information or second information is to be provided to a receiver component, wherein the first information includes a RAT identifier and the second information includes information regarding a transmit operation; and transmit a communication to the receiver component via a wireless coexistence interface between the receiver component and the transmitter component, wherein a particular portion of the communication is associated with a first value when the first information is to be provided, and wherein the particular portion is associated with a second value when the second information is to be provided. Numerous other aspects are provided.

Abstract: Aspects relate to wireless communication at a wireless communication device. The wireless communication device may include a transmitter configured to communicate using a first communication protocol, a receiver configured to communicate using a second communication protocol, different from the first communication protocol, a first antenna coupled to the transmitter, a second antenna coupled to the receiver and physically separated from the first antenna by a variable distance. The wireless communication device transmits, via the first antenna, a first transmission within a first frequency range, and receives via the second antenna, a second transmission within a second frequency range that overlaps the first frequency range. To receive the second transmission, the device may perform a radio frequency coexistence mitigation procedure based on the variable distance between the first antenna and the second antenna in response to detection of a concurrency in time between the first transmission and the second transmission.

Abstract: A user equipment (UE) includes a first communication component configured to use a first frequency band, such as ultra-wide band (UWB), and a second communication component configured to use an intermediate frequency (IF) band that overlaps with the UWB band, such as an IF millimeter wave (mmWave) band. The second communication component conducts an IF signal along an internal signal conduction line that may interfere with UWB processing. A processor of the UE is configured to detect an indication of such interference, and, in response to the indication of interference, control the second communication component to adjust a characteristic of the IF band signal to mitigate the interference, such as by reducing its signal strength. The amount by which the IF band signal strength is reduced may be controlled to achieve a desired tradeoff between various performance metrics, such as power consumption and quality of service.

Abstract: Certain aspects of the present disclosure provide techniques for protecting shared low noise amplifiers by limiting transmission power. A method that may be performed by a user equipment (UE) includes determining that a transmission by the UE on a frequency band via a first radio access technology (RAT) overlaps in time with a period that the UE is configured to receive on the frequency band via a second RAT; and limiting transmission power on the first RAT during the period.
