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.

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.

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.

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.

Abstract: A method for use of a wireless terminal device includes transmitting a Probe request frame by using a quasi-omni antenna pattern in a first channel if beam-forming training with a wireless base station device is not completed, selecting the wireless base station device as a connection destination if a Probe response frame corresponding to the Probe request frame is received from the wireless base station device, and performing the beam-forming training with the wireless base station device in a second channel if a time period for receiving the Probe response frame from the wireless base station device has passed.

Abstract: A non-personal basic service point/access point (PCP/AP) communication device includes a reception circuit that receives a DMG Beacon frame, a judging circuit that judges whether or not to transmit a frame used for beamforming training (BFT), using information relating to reception antenna gain of a PCP/AP communication device included in a DMG Beacon frame and information relating to reception power of a DMG Beacon frame, and a transmission circuit that transmits the frame used for BFT in a case of the judging circuit having judged to transmit the frame used for BFT.

Abstract: A wireless communication apparatus comprising: a frame configuration circuit that generates a transmission frame including DMG beacons, wherein sector ID fields in SSW fields included in the respective DMG beacons indicate one or more transmit sectors used for directional transmissions of the respective DMG beacons, and a field different from the sector ID field included in each DMG beacon indicates whether or not there is quasi-omni transmission; and a transmission wireless circuit that performs, by using the transmit sector indicated by the sector ID field, directional transmission on a first DMG beacon that is included in the DMG beacons and in which the field different from the sector ID field indicates non-quasi-omni transmission and performs quasi-omni transmission on a second DMG beacon that is included in the DMG beacons and in which the different field indicates quasi-omni transmission, in a BTI.
