Transmission Protection For Wireless Communications |
| 摘要 |
Systems and techniques relating to wireless communications are described. A described technique includes identifying devices to receive spatially steered data frames during a transmission opportunity (TXOP), the data frames being included in a multi-user frame; transmitting, during the TXOP, request to send (RTS) information to the identified devices; receiving clear to send (CTS) responses from the identified devices; determining a bandwidth configuration for the multi-user frame based on the CTS responses; and transmitting, during the TXOP, the multi-user frame to the identified devices in accordance with the bandwidth configuration. The bandwidth configuration can indicate one or more frequency bands that are available during at least a portion of the TXOP. |

1. A method, comprising:
identifying devices to receive spatially steered data frames during a transmission opportunity (TXOP), the data frames being included in a multi-user frame; transmitting, during the TXOP, request to send (RTS) information to the identified devices; receiving clear to send (CTS) responses from the identified devices; determining a bandwidth configuration for the multi-user frame based on the CTS responses, the bandwidth configuration indicating one or more frequency bands that are available during at least a portion of the TXOP; and transmitting, during the TXOP, the multi-user frame to the identified devices in accordance with the bandwidth configuration. |
