Abstract
A communication apparatus and method for operating a communication apparatus are provided. The communication apparatus is configured to determine whether a sub-frequency band causing interference is present among sub-frequency bands included in a reception frequency band group, and to send to another communication apparatus an interference avoidance request signal which requests the other communication apparatus to transmit signals by use of remaining sub-frequency bands except the sub-frequency band causing interference, leading to simpler and more efficient interference avoidance.
Claims18
A communication apparatus, comprising:
- a signal transmission unit to process signals of a transmission frequency band and transmit the processed signals;
- a signal reception unit to receive signals of a reception frequency band group and process the received signals;
- and
- a control unit configured to control the signal transmission unit and the signal reception unit, wherein
- the control unit comprises:
- an interference determination unit to determine whether a sub-frequency band causing interference is present among sub-frequency bands of the reception frequency band group;
- and
- an interference avoidance control unit to select a frequency hopping scheme comprising a sub-frequency band hopping sequence excluding the sub-frequency band causing interference, and to generate an interference avoidance request signal to request another communication apparatus to transmit signals according to the selected frequency hopping scheme.
A method for operating a communication apparatus, the method comprising:
- determining whether a sub-frequency band causing interference is present among sub-frequency bands belonging to a reception frequency band group;
- selecting a frequency hopping scheme comprising a sub-frequency band hopping sequence excluding the sub-frequency band causing interference;
- and
- generating an interference avoidance request signal which requests another communication apparatus to transmit signals according to the selected frequency hopping scheme.
