1. A communication apparatus comprising:
- a detection unit configured to detect received powers of a plurality of radio signals including a first radio signal and a second radio signal and received during a first predetermined time period from another apparatus;
a transmission unit configured to transmit by proxy identification information of the another apparatus; and
a prohibition unit configured to prohibit transmission of the identification information of the another apparatus by the transmission unit in a case where a change amount of received power between a first received power of the first radio signal and a second received power of the second radio signal received after the first radio signal is received is larger than a first predetermined value and the communication apparatus determines that a distance between the communication apparatus and the another apparatus is shortened in the first predetermined time period based on the change amount of received power.

16. A communication apparatus comprising:
-
a determination unit configured to determine amount change based on a change amount or received power of a distance in a predetermined time period between the communication apparatus and another apparatus based on a change amount of received power; a transmission unit configured to transmit by proxy identification information of the another apparatus; and a prohibition unit configured to prohibit transmission of the identification information of the another apparatus by the transmission unit in a case where the change amount, determined by the determination unit, of the distance between the communication apparatus and the another apparatus indicate that the distance between the communication apparatus and the another apparatus is shorter than a first predetermined value in the predetermined time period.

17. A method for controlling a communication apparatus, the method comprising:
-
detecting received powers of a plurality of radio signals including a first radio signal and a second radio signal and received during a first predetermined time period from another apparatus; transmitting by proxy identification information of the another apparatus; and prohibiting transmission of the identification information of the another apparatus in a case where a change amount of received power between a first received power of the first radio signal and a second received power of the second radio signal received after the first radio signal is received is larger than a first predetermined value and the communication apparatus determines that a distance between the communication apparatus and the another apparatus is shortened in the first predetermined time period based on the change amount of received power.

19. A method for controlling a communication apparatus, the method comprising:
-
determining a change amount of a distance between the communication apparatus and another apparatus in a predetermined time period based on a change amount of received power; transmitting by proxy identification information of the another apparatus; and prohibiting transmission of the identification information of the another apparatus in a case where the change amount, determined in the determining step, of the distance between the communication apparatus and the another apparatus indicate that the distance between the communication apparatus and the another apparatus is shorter than a first predetermined value in the predetermined time period.
