Coexistence method by requesting access to the channel |
| 摘要 |
Systems and methods for implementing coexistence by requesting access to a channel in power line communications (PLC) are described. In an illustrative embodiment, a method performed by a PLC device, such as a PLC meter, may include detecting a communication from foreign PLC device on a PLC network in response to a foreign preamble received by the PLC device, determining whether a threshold back-off duration has been reached, and transmitting a channel access request in response to a determination that the threshold back-off duration has been reached. |

1. A method comprising:
performing, by a power line communication (PLC) device,
detecting a communication from a foreign PLC device on a PLC network in response to a foreign preamble received by the PLC device;determining whether a threshold back-off duration has been reached; andtransmitting a channel access request in response to a determination that the threshold back-off duration has been reached, wherein the channel access request comprises a plurality of preamble symbols in a sequence, wherein a number of preamble symbols is determined in response to a maximum packet size supported by the PLC network. |
