  • Patent number: 11770730
    Abstract: A non-AP/PCP communication apparatus comprises: a receiver which receives a measurement request which is transmitted from an AP/PCP communication apparatus and which requests measurement used in SPSH executability determination; and a transmitter which transmits to the AP/PCP communication apparatus the result of carrying out the measurement on the basis of the measurement request. Using a first period, which is a period in which communication is to be carried out with a first non-AP/PCP communication apparatus, the transmitter and the receiver carry out communication with the first device using a first protocol, and in a second period which is included in the measurement request and in which communication is not carried out with the first device, the receiver carries out measurement of a received signal using the first protocol. The result includes information relating to the measurement of the received signal and information relating to the first protocol.
