Abstract:
1. A method of operating a wireless communication system that uses an Orthogonal Frequency Division Multiplex (OFDM) resource block structure, the method comprising: in a wireless base station, scheduling allocated resource blocks from the OFDM resource block structure to a plurality of User Equipment devices (UEs) and holding unallocated resource blocks from the OFDM resource block structure for a plurality of machine devices; in the wireless base station, decoding 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, and transferring the user data for subsequent delivery; and in the wireless base station, processing the machine data from the unallocated resource blocks to validate authorization marks in individual ones of the unallocated resource blocks, transfer portions of the machine data from the unallocated resource blocks having the valid authorization marks for subsequent delivery, and inhibit a transfer of other portions of the machine data from the unallocated resource blocks not having the valid authorization marks.
