Claim of US Patent No. 11,032,848

1. A communication system, comprising:a first node; and
a second node,
wherein the first node comprises:
a transmitter; and
first processing circuitry associated with the transmitter, the first processing circuitry being configured to:
configure a pilot signal to announce a directive signal transmission between the second node and at least one further node, the pilot signal having a narrower bandwidth than the announced directive signal transmission between the second node and the at least one further node;
include, in the pilot signal, information defining channel resources used by the announced directive signal transmission; and
transmit, via the transmitter, the pilot signal to the second node; and
wherein the second node comprises:
a receiver; and
second processing circuitry associated with the receiver, the second processing circuitry being configured to:
receive, via the receiver, the pilot signal from the second node;
predict, based on information in the pilot signal, a collision rate between an intended directive signal transmission from the first node and the announced directive signal transmission; and
access, based on the predicted collision rate, a shared media for directive signal transmission between the first node and the second node.
