1. A network node configured to communicate with a wireless device (WD), the network node comprising processing circuitry configured to:
indicate to the wireless device a set of reserved resources for machine communications in compatibility with a broadband radio access technology sharing resources in a time frame and frequency band that encompasses the set of reserved resources, the indicating using a two level bitmap operating in the time-domain, a first bitmap level of the two level bitmap indicating a first set of subframes containing reserved resources, and a second bitmap level of the two level bitmap indicating reserved symbols within an indicated subframe, wherein the first bitmap level of the two level bitmap indicates whether a subframe is available or partially available for Long Term Evolution Machine Communications (LTE-M).
