  • Patent number: 10321465
    Abstract: A radio terminal includes a receiver, a controller, and a transmitter. The receiver receives first information on radio resources for direct communication from a base station by broadcast and second information on a threshold value from the base station. The controller performs the direct communication by use of a radio resource autonomously selected among the radio resources. The receiver directly receives a radio signal from another radio terminal during performing the direct communication by use of the radio resources, and the controller compares received power of the radio signal with the threshold value of the second information. The transmitter notifies the base station of first information on the received power in response to the received power being larger than the threshold value, and does not notify the base station of the information on the received power in response to the received power being smaller than the threshold value.

  • Patent number: 10306476
    Abstract: An interface circuit in an electronic device may receive, from an access point associated with the electronic device, a frame with management information that enables the electronic device to use a spatial-reuse technique, where the electronic device, through the spatial-reuse technique, adjusts a transmit power and a channel-availability sensing threshold. Moreover, the management information may specify parameters for the spatial-reuse technique. Then, the electronic device may transmit, using the spatial-reuse technique, one or more frames to the access point based on the parameters. Furthermore, the electronic device may transmit, to the access point, feedback information that indicates communication performance during the communication between the electronic device and the access point. For example, the feedback information may include a retry rate and, more generally, communication-performance information. This feedback information may be used by the access point to modify the parameters.

  • Patent number: 10306631
    Abstract: Communication operations are optimally conducted by applying space-division multiple access in which wireless resources on a spatial axis are shared among a plurality of users. By applying an RD protocol to a communication system that conducts space-division multiple access, spatially multiplexed frames in a TXOP are made more efficient. By specifying a frame length for reverse direction frames with reverse direction permission information and having respective transmitters of reverse direction frames make their frame lengths uniform while respecting the specification, AGC operation stabilizes. Also, a transmit start time for reverse direction frames can be specified by reverse direction permission information, and respective transmitters of reverse direction frames can transmit frames at the same time while respecting the specification.

  • Patent number: 10291380
    Abstract: Multiple wireless devices in a network perform full duplex communication in which the transmission path and receiving path are spatially separated to allow simultaneous transmission and receiving. The wireless devices can either be controlled using a centralized, or point, coordination function or a distributed coordination function. A full-duplex wireless device senses the medium during transmission by itself and selectively continues the transmission when a signal is sensed on the medium. A full-duplex wireless device measures signal being transmitted by its transmitter and estimates parameters that can be used to cancel the contribution of the locally transmitted signal to the locally received signal concurrently being received during the transmission. The transmit antenna and the receive antenna of a full-duplex wireless device can be configured to be spatially isolated from each other to minimize interference between the antenna functions.
