Abstract: In a case where a wireless signal is received by Wake Up Radio (WUR), processing of searching for a new connection destination of Primary Connectivity Radio (PCR) is started based on signal strength or signal quality of the wireless signal.

Abstract: A communication apparatus that includes a first communication unit for connecting to another communication apparatus and communicating by using a PCR (Primary Connectivity Radio) function in compliance with the IEEE802.11ba standard and a second communication unit for communicating with the other communication apparatus by using a WUR (Wake Up Radio) function in compliance with the IEEE802.11ba standard, the apparatus obtains, from a signal received from the other communication apparatus by the second communication unit, a value indicating a signal intensity or a signal quality of the signal, and sets, based on the obtained value, a transmission rate of the first communication unit.

Abstract: A communication apparatus of a wireless LAN complying with the IEEE802.11 standard series determines, by executing CCA, whether a signal can be transmitted in a frequency channel to be used, transmits RTS in response to determination that the signal can be transmitted in the frequency channel, transmits data to a partner apparatus in a case where CTS is received from the partner apparatus in response to the RTS, and controls to use, in a case where the RTS is transmitted during a predetermined period after the communication apparatus shifts from a first state in which a signal cannot be received to a second state in which a signal can be received in the frequency channel, second transmission power lower than first transmission power used in a case where the RTS is transmitted during a period different from the predetermined period.

Abstract: A communication apparatus concurrently transmits packets to the partner apparatus on a plurality of links, determines whether an acknowledgment for a transmitted packet has been received on each of the plurality of links, and if it is determined that an acknowledgment for a first packet transmitted on a first link among the plurality of links has not been received, generates a changed first packet having an increased packet length by reducing a data rate of the first packet, and generating a changed subsequent packet by increasing the packet length of a packet subsequent to a packet transmitted on each of one or more links other than the first link among the plurality of links, and concurrently transmits the changed first packet on the first link and the changed subsequent packet on each of the one or more links other than the first link

Abstract: In order to be able to efficiently use joint beamforming (JB), a control apparatus operable to control a plurality of access points (APs) configured to be able to use JB, obtains, from a station (STA) which is a communication partner, reception information on a received signal strength at the STA of signals transmitted from the plurality of APs, and determines, based on the reception information, a communication parameter related to JB for communication with the STA.

Abstract: A control apparatus operable to control a plurality of access points (APs) configured to be able to use joint beamforming (JB) includes a memory containing instructions, and at least one processor for executing the instructions. The executed instructions cause the control apparatus to obtain, from a station (STA) which is a communication partner, reception information on a received signal strength at the STA of signals transmitted from the plurality of Aps, and determine, based on the reception information, a communication parameter related to JB for communication with the STA. It is determined to use JB for communication with the STA in a case where there is one or more other received signal strengths for which a strength difference from a largest received signal strength among a plurality of received signal strengths of the plurality of APs included in the reception information is within a predetermined range.

Abstract: A communication device communicates a physical (PHY) frame including a preamble and a data field. The preamble includes a Legacy Short Training Field (L-STF), a Legacy Long Training Field (L-LTF), a Legacy Signal Field (L-SIG), an EHT (Extremely High Throughput) Signal Field (EHT-SIG-A), an EHT Short Training Field (EHT-STF), and an EHT Long Training Field (EHT-LTF), and the EHT-SIG-A includes at least one subfield indicating that the communication device performs communication in a frequency band more than 160 MHz.

Abstract: An RF module includes a multi-layered substrate. A base-band IC, a memory IC, a quartz oscillator and surface-mount components are mounted on the upper surface of the multi-layered substrate. A metallic cap also is attached to the upper surface of the multi-layered substrate. A cavity is formed in the lower surface of the multi-layered substrate substantially at the center thereof. A first RF-IC and a second RF-IC are embedded in the cavity. Wiring patterns for providing connections between the base-band IC and the memory IC, through-holes, RF passive components, and the shield ground electrode pattern are disposed inside of the multi-layered substrate.
