Full duplex communication slot assignment
First Claim
Patent Images
1. A full-duplex communication method, comprising the steps of:
- establishing a set of communication slots for a dynamic distributed, multi-channel, time division communication environment, each communication slot defined by a time and a frequency parameter;
dynamically allocating, by nodes needing to communicate via the time division communication environment, communication slots from the set of established communication slots;
sharing, between a plurality of neighboring nodes using the established communication environment, data indicating those communication slots that have been allocated by nodes of the plurality of neighboring nodes and data indicating those communication slots that have been allocated by nodes neighboring the plurality of neighboring nodes; and
determining, from the shared data, which communication slots are available for full duplex unicast communication between a particular node and a selected neighboring node.

Abstract
A protocol for assignment, by an assigning node, of slots for full duplex communication in a dynamic distributed, multi-channel, time division environment is disclosed. The protocol is suitable for use with a dynamic assignment protocol such as USAP. The protocol can identify slots available for allocation for unicast communications or for allocation for broadcast communications. Nodes of the network share communication slot scheduling information. A node having data to communicate can examine the shared information and thereby identify those communication slots that are available for full-duplex communication with a selected neighboring node.
