Abstract
The present invention relates to a method comprising monitoring a first value indicative of at least one of a relative occupancy of a wireless channel, and a signal quality of a signal received from a remote communication device (10) via the wireless channel. Furthermore, the method comprises monitoring a second value indicative of a signal level (301) on the wireless channel, and, based on the first value and the second value, selectively initiating a data transmission via the wireless channel.
Claims11
A method, comprising:
- monitoring a first value indicative of a relative occupancy of a wireless channel at least partly arranged in an open spectrum, the relative occupancy is determined based on a time evolution of a signal level on the wireless channel during a predefined first time period;
- monitoring a second value that represents a signal energy including a combination of noise added with signal transmissions on the wireless channel at least partly arranged in the open spectrum during a predefined second time period at least partly different from the predefined first time period, and
- determining whether both the first value fulfills a first requirement during the predefined first time period and the second value fulfills a second requirement during the predefined second time period and at a different time than the first value fulfills the first requirement, and
- selectively initiating a data transmission via the wireless channel based on the determination of whether both the first value fulfills the first requirement during the predefined first time period and the second value fulfills the second requirement during the predefined second time period and at a different time than the first value fulfills the first requirement.
A communication device for a wireless communication network, the communication device comprising:
- at least one transceiver for communicating data via a wireless channel between the communication device and a remote communication device of the wireless communication network, wherein the wireless channel is at least partly arranged in an open spectrum;
- and
- a control unit configured to
- monitor a first value indicative of a relative occupancy of the wireless channel at least partly arranged in the open spectrum, determined based on a time evolution of a signal level on the wireless channel during a predefined first time period, and
- monitor a second value that represents a signal energy including a combination of noise added with signal transmissions on the wireless channel at least partly arranged in the open spectrum during a predefined second time period at least partly different form the first predefined first time period,
- determine whether both the first value fulfills the first requirement during the predefined first time period and the second value fulfills a second requirement during the predefined second time period and at a different time than the first value fulfills the first requirement, and
- selectively initiate a data transmission via the wireless channel based on the determination of whether both the first value fulfills the first requirement during the predefined first time period and the second value fulfills the second requirement during the predefined second time period and at a different time than the first value fulfills the first requirement.
