摘要

The present disclosure provides a radio communication device including a communication processor that connects to at least one first radio terminal through radio communication using beam forming, an information sharer that acquires first connection information including a connection situation of one or more second radio terminals connected to a second radio communication device, a switch determiner that determines whether or not to switch a connection destination of the at least one first radio terminal from the radio communication device to the second radio communication device in reference to the first connection information, and a connection switcher that, when the switch determiner determines to switch the connection destination, switches the connection destination of the at least one first radio terminal from the radio communication device to the second radio communication device.

說(shuō)明書

That is, the responder receives the first to fifth SSW packets in the sectors 1 to 5, respectively. At this time, the responder measures the respective reception reception qualities of the first to fifth SSW packets, such as the reception power, RSSI, SNR, or SINR.

After that, in a second period 5312, the responder sequentially transmits sixth to tenth SSW packets at predetermined intervals using the most-desirable transmission sector of the responder, which has been determined in the TXSS. The sixth to tenth SSW packets may be identical or different.

In synchronization with the transmission timings of the sixth to tenth SSW packets, the initiator receives each SSW packet while switching the reception sector of the initiator among the sectors 1 to 5 (see FIG. 2) with high directivity.

That is, the initiator receives the sixth to tenth SSW packets in the sectors 1 to 5, respectively. At this time, the initiator measures the respective reception reception qualities of the sixth to tenth SSW packets, such as the reception power, RSSI, SNR, or SINR.

After that, in a third period 5313, the initiator transmits an SS-Feedback packet using the most-desirable transmission sector of the initiator, which has been determined in the TXSS. The responder receives the SS-Feedback packet using the reception sector used in receiving the SSW packet with the highest reception quality, which is one of the first to fifth SSW packets and hereinafter referred to as the “most-desirable reception sector”.
