  • Patent number: 11876591
    Abstract: A reception apparatus includes reception circuitry and decoding circuitry. The reception receives a signal including a legacy header field, an enhanced directional multi-gigabit (EDMG) header field, and a data field. The decoding circuitry decodes data included in the data field of the received signal. The legacy header field includes a Length field comprising multiple bits. The reception apparatus is an EDMG terminal, and a subset of the multiple bits of the Length field included in the legacy header field is used to indicate bandwidth over which the signal is transmitted. Remaining bits of the Length field included in the legacy header field are used to indicate data length of the received signal.

  • Publication number: 20230246680
    Abstract: A communication apparatus includes a PHY frame generating circuit that generates a PHY frame including either of a short Sector Sweep frame and a Sector Sweep frame; and an array antenna that selects, based on the PHY frame, any sector from among a plurality of sectors and transmits the PHY frame. In a case where, in the PHY frame including the short Sector Sweep frame, a Direction field of the short Sector Sweep frame indicates Initiator Sector Sweep, the PHY frame generating circuit replaces a Short Sector Sweep Feedback field indicating a number of a selected best short Sector Sweep with a Short Scrambled Basic Service Set ID field indicating an abbreviated address generated from an address of a destination communication apparatus.

  • Patent number: 11700159
    Abstract: In a transmission device, a signal processing circuit generates an aggregate physical layer convergence protocol data unit (A-PPDU) by adding a guard interval to each of a first part of a first physical layer convergence protocol data unit (PPDU) transmitted over each of a first through L?th channel of a predetermined channel bandwidth, where L is an integer of 2 or greater, a second part of the first PPDU transmitted over each of an (L+1)?th through P?th channel, which is a variable channel bandwidth that is N times the predetermined channel bandwidth, where N is an integer of 2 or greater and P is an integer of L+1 or greater, and a second PPDU transmitted over the (L+1)?th through P?th channel. A wireless circuit transmits the A-PPDU.

  • Publication number: 20230208499
    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.

  • Publication number: 20230081626
    Abstract: In a case where an A-BFT period is not present in a BI, a PCP/AP uses a format that includes an Unsolicited RSS Enabled sub-field for indicating support for responding to unsolicited RSSs within a CBAP, for a Beacon Interval Control field of a DMG beacon frame used for executing a BTI-ISS. For example, in a case where it is indicated that responding to unsolicited RSSs within a CBAP is supported, the PCP/AP sets the value of the Unsolicited RSS Enabled sub-field to 1. In a case where the value of the Unsolicited RSS Enabled sub-field included in a received DMG beacon frame is 1, a STA responds with an unsolicited CBAP-RSS.
