| 摘要 |
The present invention relates to a communication device (200) for communication over a shared transmission medium (270). In accordance with a first aspect of the invention, the communication device comprises a transmitter (210) for transmitting communication signals through a transmitter output terminal (211), a receiver (220) for receiving communication signals through a receiver input terminal (221), and a coupling unit (230) for coupling the transmitter output terminal and the receiver input terminal to the shared transmission medium, and comprising a first filter (231) for passing communication signals from/to the shared transmission medium within a first communication frequency range (FLOW), and a second filter (232) for passing communication signals from/to the shared transmission medium within a second communication frequency range (FHIGH) disjoint from the first communication frequency range. The coupling unit further comprises a configurable switch (233) for connecting the transmitter output terminal to the first filter and the receiver input terminal to the second filter in a first switching state (S1), or for connecting the transmitter output terminal to the second filter and the receiver input terminal to the first filter in a second switching state (S2). The communication device further comprises a switching controller (240) for selecting between the first or second switching state based on configuration information (conf_info) received from a remote access node (11) coupled to the communication device via the shared transmission medium. The present invention also relates to a method for assigning communication resources to a plurality of such communication devices. |
