PROGRESSIVE MULTI-CRITERIA BASED SIDELINK RESOURCE ALLOCATION

摘要

A radio device (20) monitors a contiguous set of radio resources to determine radio resources estimated to be used by one or more other radio devices (30, 40). The radio device (20) selects a first subset of radio resources from the contiguous set according to a first criterion configured to mitigate overlap of the first subset with the radio resources estimated to be used by one or more other radio devices (30, 40). Further, the radio device (20) selects a second subset of radio resources from the contiguous set according to a second criterion configured to mitigate fragmentation of the contiguous set by the selected subset and the radio resources estimated to be used. The radio device (20) sends a first sidelink radio transmission (206) on the first subset. The first sidelink radio transmission (206) indicates a reservation of the second subset. Further, the radio device (20) sends a second sidelink radio transmission (208) on the second subset.
