1. A communication device, which communicates with another communication device, comprising:
- a transmission circuit that transmits a transmission signal under a first transmission condition;
a reception circuit that receives a reception result of the transmission signal under a first reception condition and the first reception condition; and
an adjustment circuit that transmits first information from the transmission circuit to the another communication device, based on the reception result and the first reception condition before changing the first transmission condition to a second transmission condition in which power consumption of the communication device is less than that in the first transmission condition, the first information allowing the another communication device to adjust the first reception condition to a second reception condition in which power consumption of the another communication device is less than that in the first reception condition.

10. A communication device, which communicates with another communication device, comprising:
-
a reception circuit that receives a transmission signal transmitted from the another communication device under a first reception condition; a transmission circuit that transmits a reception result of the transmission signal received by the reception circuit and the first reception condition to the another communication device; and an adjustment circuit that adjusts the first reception condition to a second reception condition in which power consumption of the communication device is less than that in the first reception condition in response to a receipt notification transmitted from the another communication device based on the reception result and the first reception condition, before the another communication device changes a first transmission condition to a second transmission condition in which power consumption of the another communication device is less than that in the first transmission condition.

11. A communication system comprising first and second communication devices that are coupled to each other,
wherein the first communication device includes: -
a first transmission circuit that transmits a transmission signal under a first transmission condition; a first reception circuit that receives a reception result of the transmission signal under a first reception condition and the first reception condition; and a first adjustment circuit that transmits first information from the transmission circuit to the second communication device, based on the reception result and the first reception condition before changing the first transmission condition to a second transmission condition in which power consumption of the first communication device is less than that in the first transmission condition, the first information allowing the second communication device to adjust the first reception condition to a second reception condition in which power consumption of the second communication device is less than that in the first reception condition; and wherein the second communication device includes; a second reception circuit that receives the transmission signal transmitted from the first communication device under the first reception condition; a second transmission circuit that transmits the first reception condition and the reception result of the transmission signal received by the second reception circuit to the first communication device; and a second adjustment circuit that adjusts the first reception condition of the second reception circuit to the second reception condition based on the reception result and the first reception condition in response to a receipt notification transmitted from the first communication device, before the first communication device changes the first transmission condition to the second transmission condition.

12. A communication method comprising:
-
transmitting a transmission signal under a first transmission condition from a transmission circuit of a communication device, which communicates with another communication device; receiving, with a reception circuit of the communication device, a reception result of the transmission signal under a first reception condition and the first reception condition; and transmitting first information from the transmission circuit to the another communication device, based on the reception result and the first reception condition before changing the first transmission condition to a second transmission condition in which power consumption of the communication device is less than that in the first transmission condition, the first information allowing the another communication device to adjust the first reception condition to a second reception condition in which power consumption of the another communication device is less than that in the first reception condition.

13. A method for adjusting a communication device, which communicates with another communication device, the method comprising:
-
receiving a transmission signal transmitted from the another communication device with a reception circuit of the communication device that operates under a first reception condition; transmitting, from a transmission circuit of the communication device, the first reception condition and reception result of the transmission signal received by the reception circuit and to the another communication device; and adjusting, with an adjustment circuit of the communication device, the first reception condition to a second reception condition in which power consumption of the communication device is less than that in the first reception condition in response to a receipt notification transmitted from the another communication device based on the reception result and the first reception condition, before the another communication device changes a first transmission condition to a second transmission condition in which power consumption of the another communication device is less than that in the first transmission condition.
