Abstract

In CE4, a communication terminal transmits data including a latency_off value “1”. After receiving the data, an environment information measuring apparatus transmits data since a latency counter value is “0”. The latency counter value becomes “2” and a latency_off counter value becomes “1”. In CE5, the communication terminal transmits data including a latency_off value “0”. Since each of the latency counter value and the latency_off counter value is not “0”, the environment information measuring apparatus does not receive the data from the communication terminal. The latency counter value becomes “1” and the latency_off counter value becomes “0”. In CE6, since the latency_off counter value is “0”, the environment information measuring apparatus receives the data from the communication terminal.

Claims

1. A radio communication apparatus configured to perform radio communication with a radio communication apparatus of a communication partner, comprising:

a control unit configured to set that transmission/reception with the radio communication apparatus of the communication partner is not necessary; and

a communication unit configured to;

receive as received data, from the radio communication apparatus of the communication partner, information to control reception in a case where the transmission/reception is not necessary; and

transmit data to the radio communication apparatus of the communication partner,

wherein the control unit controls reception of data from the radio communication apparatus of the communication partner based on the information to control reception in a case where the transmission/reception is not necessary,

wherein the control unit determines, based on the received data, whether a data transmission condition to transmit data to the communication apparatus of the communication partner is satisfied, and

wherein when it is determined that the data transmission condition is satisfied, the communication unit transmits the data to the radio communication apparatus of the communication partner.

2. A radio communication method of performing radio communication with a radio communication apparatus of a communication partner, the method comprising:

setting unnecessity of transmission/reception to set that transmission/reception with the radio communication apparatus of the communication partner is not necessary;

receiving as received data, from the radio communication apparatus of the communication partner, information to control reception in a case where the transmission/reception is not necessary;

controlling reception of data from the radio communication apparatus of the communication partner based on the information to control reception in a case where the transmission/reception is not necessary;

determining, based on the received data, whether a data transmission condition to transmit data to the communication apparatus of the communication partner is satisfied; and

when it is determined that the data transmission condition is satisfied, transmitting the data to the radio communication apparatus of the communication partner.

3. A non-transitory computer-readable recording medium having a program stored thereon which is executable to control a computer configured to perform radio communication with a radio communication apparatus of a communication partner to perform functions comprising:

setting unnecessity of transmission to set that transmission/reception with the radio communication apparatus of the communication partner is not necessary;

receiving as received data, from the radio communication apparatus of the communication partner, information to control reception in a case where the transmission/reception is not necessary;

controlling reception of data from the radio communication apparatus of the communication partner based on the information to control reception in a case where the transmission/reception is not necessary;

determining, based on the received data, whether a data transmission condition to transmit data to the communication apparatus of the communication partner is satisfied; and

when it is determined that the data transmission condition is satisfied, transmitting the data to the radio communication apparatus of the communication partner.
