Abstract
Before start of streaming, a server apparatus obtains from client apparatuses their respective numbers of antenna combinations, determines a training time taccording to the maximum of the numbers of antenna combinations, and notifies the client apparatuses of the training time t. Each client apparatus determines a training time trequired to estimate transmission path conditions for one antenna combination, based on the training time t. The server apparatus transmits a training signal during the training time t. Each client apparatus estimates transmission path conditions using the training signal during the training time tfor each antenna combination, and selects and sets an antenna combination based on the estimated transmission path conditions.
