Abstract
Selecting a control channel set in a communication system involves monitoring received signals to identify a plurality of nodes of interest (NOI) and determining Eb/N0 values for a plurality of control channels. For this purpose, a data metric and spectral data can be provided to the communication device by the respective NOI for which Eb/N0 values are being determined. A comparison is made of the Eb/N0 values for all NOI to select an optimal control channel set. The optimal control channel set is then used by the communication device to transmit the control channel information to the plurality of NOI.
Claims27
A method for selecting a control channel set from a plurality of control channel sets, comprising:
- monitoring in a communication device received signals to identify a plurality of nodes of interest (NOI);
- for each of the NOI, respectively determining by the communication device Eb/N0 values for a plurality of control channels by using one or more of a data metric and spectral data provided to the communication device by the respective NOI for which Eb/N0 values are being determined;
- comparing the Eb/N0 values of the control channels determined for all NOI to select an optimal control channel set comprising a plurality of control channels on which the communication device will transmit the control channel information to the plurality of NOI.
A method for selecting a diversity control channel in a network communication system, comprising:
- monitoring by a communication device received signals to identify a plurality of neighbor nodes of interest (NOI) which utilize two or more control channel sets, each comprising a plurality of diversity control channels, each diversity control channel respectively defined by a sub-band having a predetermined frequency range;
- estimating by the communication device the received control channel power respectively associated with each NOI in a plurality of the diversity control channels which are actively in use by the NOI;
- obtain a composite NOI signal power for each of the diversity control channels by summing the received control channel power for the plurality of NOI within each sub-band;
- for each of the diversity control channels, using the composite NOI signal power and information comprising the total power present in each sub-band to determine an interference power that is exclusively associated with unknown interference and noise in the sub-band;
- and
- within each control channel set, selecting a preferred diversity control channel from the plurality of diversity control channels which has the interference power of least magnitude.
A communication device, comprising:
- a receiver;
- a transmitter;
- and
- a processor programmed for selecting a control channel set from a plurality of control channel sets by

- for each of the NOI, respectively determining Eb/N0 values for a plurality of control channels by using one or more of a data metric and spectral data provided to the communication device by the respective NOI for which Eb/N0 values are being determined, and
- comparing the Eb/N0 values of the control channels determined for all NOI to select an optimal control channel set comprising a plurality of control channels on which the communication device will transmit the control channel information to the plurality of NOI.
A communication device, comprising:
- a receiver;
- a transmitter;
- and
- a processor programmed with a set of instructions for selecting a diversity control channel in a network communication system, by
- monitoring received signals to identify a plurality of neighbor nodes of interest (NOI) which utilize two or more control channel sets, each comprising a plurality of diversity control channels, each diversity control channel respectively defined by a sub-band having a predetermined frequency range,
- estimating the received control channel power respectively associated with each NOI in a plurality of the diversity control channels which are actively in use by the NOI,
- obtaining a composite NOI signal power for each of the diversity control channels by summing the received control channel power for the plurality of NOI within each sub-band,
- for each of the diversity control channels, using the composite NOI signal power and information comprising the total power present in each sub-band to determine an interference power that is exclusively associated with unknown interference and noise in the sub-band, and
- within each control channel set, selecting a preferred diversity control channel from the plurality of diversity control channels which has the interference power of least magnitude.
