When the new device receives the HELLO message from a neighbor, the new device responds with the RSREQ message to ask for the route and subframe information.
When the neighbor device receives the RSREQ from the new device, the neighbor device has to respond with the message including the route and subframe information.
As a result, the new device is able to obtain the neighbor's route and subframe information and update its routing/subframe tables.
These control messages include the following: route advertisement (RADV), JREQ, join confirm (JCNF), channel advertisement (CADV), HELLO, route information request (RREQ), and route and subframe information request (RSREQ).
However, in this case, because the device already knows its neighbor's subframe occupation state, it requests only the route information with the RREQ message, except for the subframe information.
Each device in the network maintains its own subframe table, whose entries include the device ID, subframe information (i.e., a pair of frequency index and time index), hop count, and sequence number of each device within the interference range.

In the first phase (see Figure1), the antennas are swept in N/L subframes to obtain information about all antennas.
Similar to state-of-the-art speech codecs, the analysis frame is divided by subframes to obtain pitch information.
The system is operated using time division duplexing with four subframes: the downlink feedback subframe, the downlink data subframe, the uplink contention subframe, and the uplink data subframe.
On the other hand, pedestrian or vehicular users feedback more information during one subframe, e.g., the min ∀m∈qSINRi,k,mmin where q is a Resource Block Group (RGB) and consists of a set of consecutive in frequency and time PRBs.
Figure 5 shows the data subframe structure.
