After data becomes available for transmission, the transmitting device performs an autonomous radio resource allocation to select radio resources within a transmission win- dow to be used for transmitting the data, based on the informa- tion acquired by the resource sensing procedure during a sensing window. The autonomous radio resource allocation comprises selecting radio resources in primary subframes of the transmis- select data resources in primary subframes resource sensing procedure radio resource reservations radio resource energy measurements data resources In pimary mammas found?

The secondary subframes correspond to those subframes in the sensing window during which the transmitting device did not perform the resource sens- ing procedure, and the primary subframes correspond to those subframes in the sensing window during which the transmitting device did perform the resource sensing procedure.
