Abstract
Official abstract text for this publication.
A wireless communication method including: when transmitting data from at least one of a plurality of transmission apparatuses to a reception apparatus using a radio resource, selecting a first transmission scheme or a second transmission scheme based on a status of transmission from the plurality of transmission apparatuses, the first transmission scheme in which the plurality of transmission apparatuses transmit same data to same reception apparatus using same radio resource, the second transmission scheme in which one transmission apparatus of the plurality of transmission apparatuses transmits the data to the reception apparatus using the radio resource.
First claim
Opening claim text (preview).
What is claimed is: 1 . A wireless communication method comprising: when transmitting data from at least one of a plurality of transmission apparatuses to a reception apparatus using a radio resource, selecting a first transmission scheme or a second transmission scheme based on a status of transmission from the plurality of transmission apparatuses, the first transmission scheme in which the plurality of transmission apparatuses transmit same data to same reception apparatus using same radio resource, the second transmission scheme in which one transmission apparatus of the plurality of transmission apparatuses transmits the data to the reception apparatus using the radio resource. 2 . The wireless communication method according to claim 1 further comprising: receiving information on the status of the transmission from the plurality of transmission apparatuses. 3 . The wireless communication method according to claim 1 , wherein the status of the transmission from the plurality of transmission apparatus includes an interference that occurs in accordance with the transmission from the plurality of transmission apparatus. 4 . The wireless communication method according to claim 2 , wherein a specified transmission apparatus among the plurality of transmission apparatus receives the information from a different transmission apparatus. 5 . The wireless communication method according to claim 3 , wherein the first transmission scheme is selected when the interference is relatively low, the second transmission scheme is selected when the interference is relatively high. 6 . The wireless communication method according to claim 4 , wherein the different transmission apparatus receives a report on the interference, from a reception apparatus controlled by the different transmission apparatus. 7 . The wireless communication method according to claim 1 , wherein the radio resource includes a time component and a frequency component. 8 . The wireless communication method according to claim 1 , wherein when the second transmission scheme is selected, another transmission apparatus of the plurality of transmission apparatuses transmit no data using the radio resource. 9 . A wireless communication apparatus comprising: a memory; and a processor configured, when transmitting data from at least one of a plurality of transmission apparatuses to a reception apparatus using a radio resource, to select a first transmission scheme or a second transmission scheme based on a status of transmission from the plurality of transmission apparatuses, the first transmission scheme in which the plurality of transmission apparatuses transmit same data to same reception apparatus using same radio resource, the second transmission scheme in which one transmission apparatus of the plurality of transmission apparatuses transmits the data to the reception apparatus using the radio resource. 10 . The wireless communication apparatus according to claim 9 , wherein the processor is configured to receive information on the status of the transmission from the plurality of transmission apparatuses. 11 . The wireless communication apparatus according to claim 9 , wherein the status of the transmission from the plurality of transmission apparatus includes an interference that occurs in accordance with the transmission from the plurality of transmission apparatus. 12 . The wireless communication apparatus according to claim 10 , wherein the wireless communication apparatus is included in the plurality of transmission apparatus and receives the information from a different transmission apparatus. 13 . The wireless communication apparatus according to claim 11 , wherein the first transmission scheme is selected when the interference is relatively low, the second transmission scheme is selected when the interference is relatively high. 14 . The wireless communication apparatus according to claim 12 , wherein the different transmission apparatus receives a report on the interference, from a reception apparatus controlled by the different transmission apparatus. 15 . The wireless communication method according to claim 9 , wherein the radio resource includes a time component and a frequency component. 16 . The wireless communication method according to claim 9 , wherein when the second transmission scheme is selected, another transmission apparatus of the plurality of transmission apparatuses transmit no data using the radio resource.
