Abstract

A wireless communication device includes: a receiving unit that receives a first signal storing first information with which precision or accuracy of transmission power is recognized; and a transmission unit that transmits a second signal regarding permission of multiple access that allows simultaneous communication with at least one first wireless communication device identified on the basis of the first information. A wireless communication device includes: a transmission unit that transmits a first signal storing first information with which precision or accuracy of transmission power is recognized; a receiving unit that receives a second signal regarding permission of multiple access that allows simultaneous communication after the transmission of the first signal; and a control unit that controls transmission of a third signal on the basis of the second signal.

First claim

1 . A wireless communication device comprising:
a receiving unit that receives a first signal storing first information with which precision or accuracy of transmission power is recognized; and a transmission unit that transmits a second signal regarding permission of multiple access that allows simultaneous communication with at least one first wireless communication device identified on a basis of the first information.

2 . The wireless communication device according to claim 1 , wherein the at least one first wireless communication device is identified on a basis of the first information and a threshold value regarding the first information.

3 . The wireless communication device according to claim 2 , wherein the transmission unit transmits the second signal to a first transmission source of the first signal storing the first information that is equal to or greater than the threshold value.

4 . The wireless communication device according to claim 3 ,
wherein the transmission unit transmits the second signal to a second transmission source of the first signal storing the first information that is less than the threshold value, and a communication parameter that is different from a communication parameter stored in the second signal that is transmitted to the first transmission source is stored in the second signal transmitted to the second transmission source.

5 . The wireless communication device according to claim 4 , wherein the communication parameter includes a communication parameter regarding noise resistance for communication.

6 . The wireless communication device according to claim 2 , wherein the transmission unit does not transmit the second signal to the first transmission source of the first signal storing the first information that is less than the threshold value, or transmits a signal indicating permission of single access.

7 . The wireless communication device according to claim 1 , wherein the second signal includes a transmission permission signal indicating permission of multiple access that allows simultaneous communication.

8 . The wireless communication device according to claim 1 , wherein the second signal includes a group notification signal that provides a notification about a group to which the first wireless communication device that is permitted to perform multiple access belongs, the multiple access allowing simultaneous communication.

9 . The wireless communication device according to claim 1 , wherein the multiple access that allows simultaneous communication includes frequency division multiple access, space division multiple access, or code division multiple access.

10 . The wireless communication device according to claim 1 , wherein the first information includes information regarding an error between a setting value and an actually measured value of transmission power.

11 . The wireless communication device according to claim 1 , wherein the transmission unit controls a destination of the second signal on a basis of a change in connection for communication with the first wireless communication device.

12 . The wireless communication device according to claim 1 , wherein the transmission unit controls a destination of the second signal on a basis of a change in the first information.

13 . The wireless communication device according to claim 1 ,
wherein the receiving unit receives a transmission power notification signal storing transmission power information, and the transmission unit transmits a difference notification signal storing difference information regarding a difference between the transmission power information stored in the transmission power notification signal and transmission power information estimated from reception power.

14 . The wireless communication device according to claim 13 ,
wherein the receiving unit further receives the difference notification signal, and the transmission unit controls a destination of the second signal on a basis of the difference information stored in the received difference notification signal and the estimated difference information.

15 . A wireless communication device comprising:
a transmission unit that transmits a first signal storing first information with which precision or accuracy of transmission power is recognized; a receiving unit that receives a second signal regarding permission of multiple access that allows simultaneous communication after the transmission of the first signal; and a control unit that controls transmission of a third signal on a basis of the second signal.

16 . The wireless communication device according to claim 15 ,
wherein the second signal includes a transmission permission signal indicating permission of the multiple access that allows the simultaneous communication, and the control unit controls transmission of the third signal on a basis of a communication parameter stored in the transmission permission signal.

17 . The wireless communication device according to claim 15 ,
wherein the second signal includes a group notification signal that provides a notification about a group to which the first wireless communication device that is permitted to perform the multiple access belongs, the multiple access allowing simultaneous communication, and the control unit controls transmission of the third signal in accordance with reception of a transmission permission signal indicating permission of the multiple access that allows simultaneous communication, which is directed to the group provided in the notification through the group notification signal.

18 . The wireless communication device according to claim 15 , wherein the transmission unit transmits a fourth signal that provides a notification about a change in connection for communication with a transmission source of the second signal or a change in the first information.

19 . A wireless communication method comprising, by a processor:
receiving a first signal storing first information with which precision or accuracy of transmission power is recognized; and transmitting a second signal regarding permission of multiple access that allows simultaneous communication to at least one first wireless communication device identified on a basis of the first information.

20 . A wireless communication method comprising, by a processor:
transmitting a first signal storing first information with which precision or accuracy of transmission power is recognized; receiving a second signal regarding permission of multiple access that allows simultaneous communication after the transmission of the first signal; and controlling transmission of a third signal on a basis of the second signal.
