In a method for indicate simultaneous transmit and receive (STR) capability in a Wi-Fi system, a first multi-link device (MLD) generates and sends STR capability information that indicates interference parameter information between a first link using a first bandwidth and a second link using a second bandwidth. A second device receives the STR capability information and obtains an interference parameter threshold. The second device then determines, based on the interference parameter threshold and the interference parameter information, whether the first MLD supports an STR operation on the first link and the second link.

Certain aspects of the present disclosure provide techniques for high reliability vehicle-to-everything (V2X) communications. Aspects of the present disclosure provide methods that may be performed by a first sidelink device. The first sidelink device may be a roadside unit (RSU) or a user equipment (UE).

Techniques described herein improve direct communication channel reliability in a vehicle-to-everything (V2X) communication. The techniques include a (wireless communication) device that uses a first licensed band to perform a cellular network communication through a first interface (e.g., Uu), and further uses a shared spectrum to perform a V2X communication through a direct communication channel interface. The device then monitors and compares a bandwidth requirement of the V2X communication with a bandwidth of the shared spectrum. In response to the bandwidth that is less than the bandwidth requirement, the device selects a second licensed band that includes a bandwidth that is at least equal to the bandwidth requirement. Further, the selected second licensed band is different from the first licensed band to avoid channel interference. In other embodiments, the device uses the licensed band to directly establish the V2X communication.
