Methods, systems, and devices are described for adapting access timing parameters when using DSRC spectrum. A multi-mode device may adapt at least one access timing parameter while operating within the DSRC spectrum. The at least one access timing parameter may be adapted to provide priority to transmissions of DSRC devices using the DSRC spectrum. The multi-mode device may increase a duration of a short inter-frame spacing (SIFS) to be at least equal to a duration of a SIFS used by a DSRC device.
