Abstract:
1. A method for transmitting information within a communication system, the communication system comprising a plurality of nodes communicating within a same frequency band, the method comprising the steps of: monitoring for interference to determine an interference state comprising those time periods when a node can receive communications within the frequency band with little or no interference; creating a table of the node's interference state and both optimal and suboptimal time periods for reception within the frequency band wherein the optimal and sub-optimal time periods for reception varies according the node's interference state; broadcasting the node's interference state to a plurality of neighboring nodes within the communication system; receiving a second table from at least one of the plurality of neighboring nodes, the second table being broadcast by the neighbor node to other nodes in the communication system, the second table comprising an interference state and both the optimal and sub-optimal time periods for reception within the frequency band for the neighboring node; determining, from the second table, a time to transmit to the neighboring node wherein the time can be selected from one of the optimal time and the suboptimal time periods for reception within the frequency band obtained from the second table; and transmitting information to the neighboring node during the determined time period.
