Abstract
A CCA level is made to be variable efficiently while maintaining the fairness relating to acquisition of a transmission opportunity by wireless terminal apparatuses, and thus efficiency of a radio resource is improved. Provided is a terminal apparatus that performs wireless communication with a base station apparatus, and includes; a MAC frame categorization unit categorizing MAC frames, in each of which media access control header is attached to transmission data, based on a type of MAC frame; and a QoS control unit performing a carrier sense using a first CCA level, in a case where the MAC frame is included in a first category that results from the categorization by the MAC frame categorization unit, and performing the carrier sense using a second CCA level different from the first CCA level, in a case where the MAC frame is included in a second category different from the first category.

11. A first terminal apparatus that communicates with a second terminal apparatus, the first terminal apparatus comprising:
-
a CCA unit that determines whether a radio resource is idle or busy, using a carrier sense; and a transmission unit that transmits a frame, wherein the transmission unit transmits the frame which includes MAC (Media Access Control) data including information associated with QoS (Quality of Service) and first information associated with the carrier sense. - View Dependent Claims (12, 13, 14, 15)
