METHOD AND SERVER CONFIGURED FOR ALLOCATING DOWNLINK TRANSMISSION RESOURCES AND FOR TRANSMITTING OBSTACLE DETECTION ENHANCEMENT DATA, COMPUTER PROGRAM PRODUCT, AND STORAGE MEDIUM

摘要

Obstacle detection enhancement data are transmitted from a server (120) to at least one moving conveyance (140, 141) embedding an obstacle detection system (170, 171) and an on-board wireless radio unit (160, 161) communicating with the server (120) via wireless link. To do so, downlink transmission resources are allocated to each on-board wireless radio unit (160, 161) in a transmission cycle C_n, by optimizing the difference between a distance travelled by the moving conveyance (140, 141) during a transmission cycle and a distance covered by the obstacle detection enhancement data made available to the obstacle detection system (170, 171) at a next transmission cycle C_n+1, wherein the volume of obstacle detection enhancement data expected to be transmitted during the transmission cycle C_n is determined from volume-to-distance ratio information b_k stored in a database and from actual quality of the wireless link.
