Channel reuse among communication networks sharing a communication channel

摘要

A first network device determines whether a first reference code included in at least a first transmission on a communication channel is associated with a code configured in the first network device. The communication channel is shared among a plurality of communication networks and the first reference code is associated with a first communication network of the plurality of communication networks. The first network device joins the first communication network associated with the first reference code in response to determining the first reference code is associated with the code configured in the first network device. The first network device communicates with a second network device in the first communication network using the code configured in the first network device.

1. A method comprising:
determining, at a first network device, a first correlation between a first reference code included in a first transmission on a communication channel and a second reference code configured in the first network device, wherein the communication channel is shared among a plurality of powerline communication networks, wherein the first reference code is associated with a first powerline communication network of the plurality of powerline communication networks, and the first reference code is orthogonal or quasi-orthogonal to each of a plurality of reference codes associated with others of the plurality of powerline communication networks; determining that the first correlation is above a threshold; joining, by the first network device, the first powerline communication network in response to determining that the first correlation is above the threshold; and communicating with a second network device in the first powerline communication network using the second reference code.
