Abstract:
A non-personal basic service set control point/access point (non-PCP/AP) communication apparatus includes a reception circuit, an estimation circuit, and a transmission circuit. The reception circuit receives a Directional Multi-Gigabit (DMG) Beacon frame including a sector sweep (SSW) field, the SSW field including a Parameter subfield indicating a value obtained by using a transmission Equivalent Isotropic Radiated Power (EIRP) of a PCP/AP communication partner apparatus and a reception antenna gain of the PCP/AP communication partner apparatus. The estimation circuit estimates an expected reception power at the PCP/AP communication partner apparatus by using the value of the Parameter subfield, and checks inequality between the estimated expected reception power and a receiver sensitivity value. The transmission circuit transmits a frame for Association Beamforming Training (A-BFT) if the estimated expected reception power is larger than the receive sensitivity value.
