Method for coordination of wireless transceivers of a network node and network node

摘要

A method for coordination of wireless transceivers of a network node, in particular for application in communication nodes of a vehicular network, wherein the network node is equipped with one or more wireless transceivers that are capable of simultaneously generating and/or receiving electromagnetic signals on different electromagnetic channels, the electromagnetic signals being potentially able to interfere with each other, is characterized in the steps of, for each pending packet transmission on a particular of the electromagnetic channels, checking the presence of ongoing and/or scheduled activity on one or more of the other of the electromagnetic channels, and deferring the pending packet transmission in case ongoing and/or scheduled activity is detected on one or more of the other of the electromagnetic channels, at least until the detected ongoing and/or scheduled activity on one or more of the other of the electromagnetic channels is completed. Furthermore, a corresponding network node is disclosed.

1. A method for coordination of wireless transceivers of a network node, wherein said network node is equipped with one or more wireless transceivers that are capable of simultaneously generating and/or receiving electromagnetic signals on different electromagnetic channels, comprising the steps of:
for each pending packet transmission on a particular of said electromagnetic channels, checking the presence of ongoing and/or scheduled activity on one or more of the other of said electromagnetic channels; and deferring said pending packet transmission in case ongoing and/or scheduled activity is detected on one or more of the other of said electromagnetic channels, at least until said detected ongoing and/or scheduled activity on one or more of the other of said electromagnetic channels is completed, wherein a scheduling of packet transmissions on said electromagnetic channels is realized with packet-level granularity by applying the deferring step before the packet has reached the physical layer, either at the Medium Access Control (MAC) layer or at a layer above the MAC layer, and wherein said deferring of a pending packet transmission is applied after the MAC layer access contention is completed and said network node has acquired the right to transmit.
