Method and system for minimizing channel preservation time in cellular communications on un-licensed band

A method for resource allocation signaling in a communication system, the method comprising:

• scheduling at least one resource for a receiving node of the communication system, by a transmitting node of the communication system;
• encoding information pertaining to the scheduling of the resource in a resource allocation signaling (RAS), by the transmitting node, wherein the RAS indicates resources on at least one of preceding symbols or succeeding symbols;
• and
• transmitting the RAS to the receiving node, by the transmitting node.

An apparatus for managing channel preservation time in a communication system, the apparatus comprising:

• a controller configured to:
• determine a preservation signal (PS) duration for a channel selected for communication,
• adjust said channel preservation time, based on said determined PS duration, and
• initiate communication with at least one receiving node, based on said adjusted channel preservation time;
• and
• a transceiver configured to communicate with the at least one receiving node.
