Abstract: Certain aspects of the present disclosure provide techniques for beam refinement reference signal (BRRS) design for millimeter wave (mmWave) system in shared spectrum. The techniques can include a method for wireless communication that includes transmitting at least one of a request-to-send (RTS) or a clear-to-send (CTS) within a frame using frequency resources in a shared spectrum, and including a beam refinement reference signal (BRRS) in the at least one of the RTS or CTS.
Abstract: In conventional MANETs, the functions of network discovery, route generation, and packets forwarding are performed at each node of the network. As a result, achieving routing convergence between all of the devices can be very time and resource intensive as no single node has a complete topology of the network. In contrast, the disclosed MANET with SDN architecture performs network discovery and route generation at centralized location, and packets forwarding is done separately at the node level. This new architecture allows the disclosed MANET to quickly adjust network operating characteristics whenever there is a change in the network topology.
Abstract: In a terminal device, a communication unit performs communication using one of a plurality of time slots in a communication channel. A switching unit switches a time slot for transmission when a predetermined switching condition is determined to be met by referring to a reception signal received in the communication unit and maintains the time slot for transmission until the switching condition is determined to be met again by referring to the reception signal.
Abstract: A communication system capable of a stable communication operation between a base station device and a communication terminal device. A UE is configured to communicate with an MeNB directly or through a SeNB. The UE is set to transmit, to the MeNB and the SeNB, transmission data addressed to the MeNB when an amount of the transmission data exceeds a predetermined threshold. The UE is set to transmit the transmission data not to the SeNB but to the MeNB when the amount is smaller than or equal to the threshold. The threshold is changed so that the transmission data is transmitted to the MeNB and the SeNB, when the SeNB is set to communicate with the UE with radio resources periodically allocated and the amount of the transmission data is smaller than or equal to the threshold.

Abstract: Time-division duplexing (TDD) in distributed communications systems, including distributed antenna systems (DASs) is disclosed. In one embodiment, a control circuit is provided and configured to control the TDD transmit mode of a DAS to control the allocation of time slots for uplink and downlink communications signal distribution in respective uplink path(s) and downlink path(s). The control circuit includes separate power detectors configured to detect either a transmit power level in a downlink path or a receive power level in an uplink path. If the transmit power detected in the downlink path is greater than receive power detected in the uplink path, the control circuit switches the TDD transmit mode to the downlink direction. In this manner, the control circuit does not have to control the TDD transmit mode based solely on detected power in the downlink path, where a directional coupler may leak uplink power in the downlink path.
Abstract: One or more techniques and/or systems are provided for automatically forming a wireless sensor network, implementing power management for the wireless sensor network, and/or self-healing within the wireless sensor network. For example, hub devices, configured to forward messages through the wireless sensor network to a gateway device having access to a network, may automatically join and configure into the wireless sensor network by locating and connecting to master devices using signal frequencies representing numbers of hops to the gateway device. A hub device may be configured to transition between a low power sleep state for power conservation and an awakened normal operational state for transmitting timing signals according to a duty cycle, and thus the hub device may be capable of operating from a battery. If a hub device determines that a master device has become inoperable, the hub device may automatically search for a new master device.
Abstract: Logic may comprise hardware and/or code to coordinate communications of wireless communications devices to reduce power consumption by stations. Logic may coordinate communications in an access point. Logic may generate and transmit a wake frame from the access point to the station to wake the receive circuitry of the station. Logic of the station may wake the receive circuitry from an idle mode, which may be a less linear and less sensitive mode, to a receiver (RX) active state, which is a high linear and high sensitivity mode. Once the receiver circuitry enters the RX active state, the station is ready to receive a transmission. Logic may implement the wake frame as a medium access control frame or as a null data packet, physical layer frame.
