Abstract
According to one embodiment, an electronic apparatus includes a transmitter and a processor. The transmitter transmits a signal to a first electronic apparatus with one of patterns including at least a first pattern which is a first order and which uses first to n-th frequency bands in first to n-th periods and a second pattern which is a second order different from the first order and which uses the first to n-th frequency bands in the first to n-th periods, where n is an integer greater than or equal to two. The processor switches a pattern to be used among the patterns in accordance with a communication situation.
Claims18
An electronic apparatus comprising:
- a transmitter to transmit a signal to a first electronic apparatus with one of patterns including at least a first pattern which is a first order and which uses first to n-th frequency bands in first to n-th periods and a second pattern which is a second order different from the first order and which uses the first to n-th frequency bands in the first to n-th periods, where n is an integer greater than or equal to two;
- a processor configured to switch a pattern to be used among the patterns in accordance with a communication situation;
- and
- a receiver to receive a signal from the first electronic apparatus at the same frequency band as one of the first to n-th frequency bands used at the time the signal was last transmitted to the first electronic apparatus,
- wherein the transmitter:
- transmits a first signal to the first electronic apparatus at a first frequency band,
- transmits the first signal to the first electronic apparatus at a second frequency band when a second signal is not received from the first electronic apparatus at the first frequency band after the first signal is transmitted at the first frequency band, and
- transmits the first signal to the first electronic apparatus at a third frequency band when a third signal is not received from the first electronic apparatus at the second frequency band after the first signal is transmitted at the second frequency band.
