    Abstract: Modes on power consumption are suitably set. There is provided an information processing device including a control section. When the information processing device in a first mode transitions to a second mode in which the information processing device consumes power differently than in the first mode, the control section performs control to transmit at least one frame. Upon transmitting the frame, the control section inserts into the frame information for notifying a first device compatible with the second mode that the information processing device will transition to the second mode, and information for causing a second device incompatible with the second mode to suppress transmission.

    Abstract: It is possible to rapidly discover a wireless terminal as a connection partner without preliminarily sharing information related to a scan.A search parameter for searching for a search target wireless terminal is determined depending on preliminarily set correspondence relation from given information. The search processing is performed based on the search parameter to discover the search target wireless terminal. For example, the given information is position information of the wireless terminal, information unique to the search target wireless terminal, and the like. Moreover, the search parameter is a wireless system, a wireless channel, a network identifier, search execution timing, and the like.

    Abstract translation: 可以在不预先共享与扫描有关的信息的情况下，将无线终端快速地发现为连接伙伴。 用于搜索搜索目标无线终端的搜索参数根据预先设定的来自给定信息的对应关系来确定。 基于搜索参数执行搜索处理以发现搜索目标无线终端。 例如，给定信息是无线终端的位置信息，搜索对象无线终端唯一的信息等。 此外，搜索参数是无线系统，无线信道，网络标识符，搜索执行定时等。
