Abstract
A first apparatus communicates with a second apparatus via a first link in a first frequency band and via a second link in a second frequency band different than the first frequency band by performing operations. For example, the first apparatus performs an independent enhanced distributed channel access (EDCA) on each of the first link and the second link. Then, the first apparatus obtains a transmit opportunity (TXOP). Next, the first apparatus synchronizes a starting time and/or an ending time of a transmission and a reception on the first link and the second link to avoid causing an in-device coexistence (IDC) interference due to the transmission and the reception occurring simultaneously. Alternatively, the first apparatus refrains from transmitting and receiving on the first link and the second link simultaneously to avoid causing the IDC interference.
