Location based use of the DSRC spectrum

摘要

Methods, systems, and devices are described for using location information to determine whether to use at least a portion of a dedicated short range communications (DSRC) spectrum. Current location information of a multi-mode device is determined. The multi-mode device is operating outside of the DSRC spectrum. The current location information is used to determine whether the multi-mode device is located outside of geographical region attributed to DSRC transmissions. Upon determining that the multi-mode device is located outside of the geographical region, at least a portion of the DSRC spectrum is used for transmissions by the multi-mode device.

1. A method for using location information to determine whether to use at least a portion of a dedicated short range communications (DSRC) spectrum, comprising:
determining current location information of a multi-mode mobile device; using the current location information to determine whether the multi-mode mobile device is located outside of any geographical region allocated for use of DSRC spectrum for DSRC transmissions; upon determining that the multi-mode mobile device is located outside of any geographical region allocated for use of DSRC spectrum for DSRC transmissions, using at least a portion of the DSRC spectrum; and upon determining that the multi-mode device is not located outside of any geographical region allocated for use of DSRC spectrum for DSRC transmissions, continuing to perform communications outside of the DSRC spectrum via Unlicensed National Infrastructure (U-NII) spectrum; wherein any geographical region allocated for use of the DSRC spectrum for DSRC transmissions is within a predetermined distance from a road.
