Abstract: The present disclosure relates to a wireless base station and a terminal device that can shorten time required for sounding information collection by a plurality of wireless base stations and suppress deterioration of following accuracy. When a wireless base station as a master performs channel measurement with a terminal device, it is possible to transmit channel measurement frames in wireless base stations including the wireless base station at the same timing or at different timings only by instructing another wireless base station to perform a channel measurement, and also transmitting a Sounding Trigger frame including a transmission timing and a transmission stream of a channel measurement frame once. The present disclosure can be applied to communication systems in wireless LAN.
