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.

Adaptive radio frequency coexistence mitigation

A first device may establish, with a second device, a short-range wireless communications link. The first device may determine a time interval between each of a set of packets to be transmitted over a short-range wireless communications link with a second device. The first device may encode data with a bitrate that is based on the time interval. The first device may packetize the encoded data in the set of packets. The first device may transmit the set of packets to the second device or the short-range wireless communications link, and each of the set of packets may be separated by the time interval when transmitted.

Low-latency audio streaming with communication coexistence

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be communicating on a radio frequency spectrum band of a first radio access technology (RAT) using a set of antennas. The UE may reconfigure at least one antenna of the set of antennas to perform a first scan on the radio frequency spectrum band of a second RAT. The UE may determine, based on the first scan, whether to reconfigure a remaining portion of the antennas of the set of antennas to perform a second scan on the radio frequency spectrum band of the second RAT.

Radio frequency spectrum band harmonization

A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus is configured to identify interference information associated with at least one traffic stream. The apparatus is further configured to transmit a message to an access point. The message includes a stream ID associated with the interference information and with the at least one traffic stream. The message includes the interference information, and the interference information includes an offset value and an interval/duration value.

WLAN AP-assisted multi-way coexistence

In a multi-radio user equipment, communications on a Long Term Evolution (LTE) radio and Wireless Local Area Network (WLAN) radio operating in Wi-Fi mode may be aligned to reduce interference between the two radios. Communications of the WLAN radio may be aligned to the LTE radio using Notice of Absence (NoA) functionality.

Multi-radio coexistence

An apparatus and method are disclosed for effectively and efficiently arbitrating concurrent usage between WLAN and Bluetooth access technologies for co-located wireless devices. A state level arbiter determines state and relevant parameters of a WLAN module and of a Bluetooth module of a wireless transceiver unit. The state level arbiter uses the state and relevant parameters to determine which access technology (WLAN or Bluetooth) or combination of the access technologies (WLAN or Bluetooth) will provide the best concurrent performance for wireless transmissions at a given time for specific Bluetooth states and WLAN states.
