Abstract
A wireless base station schedules allocated resource blocks from an OFDM resource block structure to a UEs and holds unallocated resource blocks from the OFDM resource block structure for machines. The base station decodes wireless OFDM signals based on the OFDM resource block structure to obtain user data from the UEs using the allocated resource blocks and to obtain machine data from the machine devices using the unallocated resource blocks. The base station processes the machine data from the unallocated resource blocks to validate authorization marks in individual resource blocks. The base station transfers portions of the machine data having the valid authorization marks for delivery. The base station inhibits the transfer of machine data not having the valid authorization marks.
