Circuit and method for operating a node in a radio network

摘要

A circuit and a method for operating a node in a radio network, whereby nodes of the same radio network have a common network ID and each node individually is assigned a node ID, wherein during the reception of a current packet by a receiving circuit of the node, an address contained in the packet is determined, wherein reception of the current packet is continued when the determined address agrees with the network ID of the node and the node ID of the node, and wherein during reception of the current packet, the reception of the current packet is terminated and the receiving circuit is controlled based on a case decision, when the determined address does not agree with the network ID of the node or the node ID of the node.

1. A node in a radio network comprising:
a receiving circuit configured to receive a first portion of a current packet, wherein the node is one of a plurality of nodes in a radio network that have a common network ID and an individual node ID; and an evaluation circuit connectable to the receiving circuit and configured to:
examine the first portion of the current packet to identify an address contained in the current packet;if the identified address corresponds to the common network ID of the node and the individual node ID of the node, cause the receiving circuit to continue to receive a second portion of the current packet;if the identified address does not correspond to the common network ID of the node or the individual node ID of the node:
cause the receiving circuit to terminate reception of the second portion of the current packet;synchronize the receiving circuit to a new preamble;determine a current reception energy of the current packet; andbased at least on the determined current reception energy, determine one or more of an upper threshold and a lower threshold,wherein synchronizing the receiving circuit to the new preamble is initiated if the current reception energy in the transmission channel exceeds the upper threshold or falls below the lower threshold.
