Wireless communication method, wireless communication system, and wireless communication apparatus |
摘要 |
A wireless communication method includes: detecting, at a wireless communication apparatus, a collision of data transmitted from a plurality of wireless communication terminals during a first period that is in a communication-enabled state; shifting, when the collision has been detected, a second period, which belongs to the same frame as the first period and is in a communication-disabled state, to a communication-enabled state; transmitting, at the wireless communication apparatus, a request to the plurality of wireless communication terminals for retransmission of the data and receiving data transmitted from the plurality of wireless communication terminals in response to the request, using the shifted second period. |

1. A wireless communication method comprising:
detecting, at a wireless communication apparatus, a collision of data transmitted from a plurality of wireless communication terminals during a first period that is in a communication-enabled state; shifting, when the collision has been detected, a second period, which belongs to the same frame as the first period and is in a communication-disabled state, to a communication-enabled state; transmitting, at the wireless communication apparatus and using the shifted second period, a request to the plurality of wireless communication terminals for retransmission of the data and receiving data transmitted from the plurality of wireless communication terminals in response to the request; and counting the number of times data has been received in the second period, wherein the shifting decreases the shifted second period when the number of times data has been received is below a first given value, and increases the shifted second period when the number of times data has been received is above a second given value that is greater than the first given value. |
