Abstract
One embodiment of the present invention relates to a method for communicating over a multi-carrier communication channel. In the method, sub-carrier frequencies that are reserved for communication between a pair of nework nodes are associated with different sub-carrier groups, where the sub-carriers of each sub-carrier group are assigned a common transmission characteristic that is independent of the transmission characteric for the other sub-carrier groups. Other methods and devices are also disclosed.
Claims25
A method for communicating over a multi-carrier communication channel of a network, comprising:
- ascertaining a number of subcarriers over which a transmitting and receiving node in the network are to exchange a communication signal;
- grouping the number of sub-carriers into sub-carrier groups, at least one sub-carrier group having multiple sub-carriers and each sub-carrier group having a bitloading or gain configuration that is independent of the bit-loading or gain configurations respectively associated with the other sub-carrier groups.
A method for communicating over a multi-carrier communication channel, comprising:
- receiving a probe signal from a transmitting node over sub-carrier frequencies on which the transmitting network node communicates with a receiving network node;
- assigning the sub-carrier frequencies to different sub-carrier groups as a function of the received probe signal, where multiple sub-carriers in each sub-carrier group follow a bitloading or gain configuration that is independent of the bitloading or gain configurations respectively associated with the other sub-carrier groups.
A method for communicating over a multi-carrier communication channel, comprising:
- transmitting a probe signal over sub-carrier frequencies to a receiving network node;
- receiving a bit-loading table based on the probe signal in which the sub-carriers are associated with a number of sub-carrier groups, each sub-carrier group having sub-carriers that follow a common bit-loading distribution that is independent of the bitl-loading distributions for the other sub-carrier groups.
A receiving network node configured to be associated with a network having a number of nodes, comprising:
- a receiver configured to receive a probe signal over sub-carrier frequencies that are reserved for communication with a transmitting node;
- noise analyzer circuitry configured to analyze the received probe signal and determine a number of bits that the transmitting node should load onto each of the sub-carrier frequencies and further configured to group the sub-carrier frequencies into multiple sub-carrier groups, at least one sub-carrier group having multiple sub-carriers, where the sub-carriers within each sub-carrier group share a common transmission characteristic that is independent of the other sub-carrier groups.
A transmitting network node configured to be associated with a network having a number of nodes, comprising:
- a transmitter configured to transmit a probe signal over a number of sub-carrier frequencies that are associated with a receiving network node;
- a receiver configured to receive at least one group message, where the group message specifies how the sub-carriers are to be grouped into multiple sub-carrier groups for subsequent transmissions, where the sub-carriers within each sub-carrier group share a common transmission characteristic that is independent of the other sub-carrier groups.
