A communication apparatus that performs communication that conforms to an IEEE802.11 series standard in accordance with an OFDMA (Orthogonal Frequency Division Multiple Access) scheme, the communication apparatus comprising:
- at least one memory that stores a set of instructions;
- and
- at least one processing circuit,
- wherein the communication apparatus is caused, by the at least one processing circuit executing the set of instructions, to perform and/or the at least one processing circuit itself performs operations comprising:
- receiving, from a base station, a trigger frame that includes first information in which a plurality of resource units obtained by dividing a channel is associated with AIDs (Association Identifiers) that are identification information of a plurality of communication apparatuses;
- transmitting a signal in a resource unit that is specified with use of an AID for the communication apparatus in the trigger frame, wherein the signal is transmitted with transmission power that is determined with use of both second information and a reception signal intensity, wherein the second information is information that is able to be acquired by analyzing the trigger frame and is used for determining the transmission power when the communication apparatus performs signal transmission, and wherein the reception signal intensity is an intensity of a signal communicated between the communication apparatus and the base station;
- and
- controlling the signal transmission so that the signal is transmitted with first transmission power in a case where the reception signal intensity is a first intensity and the signal is transmitted with second transmission power that is higher than the first transmission power in a case where the reception signal intensity is a second intensity that is less than the first intensity.
