An adapter for enabling full-duplex wireless communications is described, along with methods for operating the adapter. The adapter operates as an intermediary between a transmit antenna and receive antenna on the one hand, and a transceiver on the other hand. The adapter communicates with the transceiver using different frequencies for outbound and inbound radio-frequency signals. However, with respect to the transmit antenna and receive antenna, the adapter transmits outbound and receives inbound radio frequency signals using the same frequency. The adapter includes cancellation circuitry to reduce the self-interference cause by transmitting and receiving on the same frequency.

The disclosed subject matter relates to facilitating uplink communication waveform selection in wireless communication systems, and more particularly Fifth Generation (5G) wireless communication systems.

A dynamic data distribution method in a private network and an associated electronic device are provided. The private network includes: a first pairing connection between a first electronic device, a second electronic device, and a second pairing connection between the first electronic device and a third electronic device. The method includes the steps of: receiving sensor data from the second electronic device by the first electronic device; notifying the second electronic device to build a third pairing connection with the third electronic device according to a determination result between the first electronic device and the third electronic device; and terminating the first pairing connection and retrieving the sensor data from the second electronic device through the third electronic device by the first electronic device when the third pairing connection has been built.

A source node selects a plurality of original data components to transfer to at least one destination node. A plurality of transmitting nodes cooperatively encodes the original data components to generate a plurality of subspace coded components and a corresponding code matrix. Each of the transmitting nodes transmits a subset of the plurality of subspace coded components and corresponding code matrix, wherein at least one of the transmitting nodes has a rank that is insufficient for decoding the plurality of subspace coded components. A destination node may employ a plurality of receiving nodes to cooperatively receive a plurality of subspace coded components and their corresponding code vectors, wherein the rank of at least one of the receiving nodes is insufficient for decoding the subspace coded components. The destination node builds up the dimension of the subspace spanned by code vectors it collects from the receiving nodes and then decodes the subspace coded components.

Methods, systems, and devices for wireless communication are described. A device using a first radio access technology (RAT) to communicate over an unlicensed radio frequency spectrum band may identify a communication pattern for a transmission using a second RAT over the unlicensed radio frequency spectrum band. The identification may be based at least in part on signaling received by the device. The device may determine, based at least in part on the communication pattern, a time period for attempting to transmit the unlicensed radio frequency spectrum band using the first RAT.

A communication apparatus includes control circuitry and a transmitter. In operation, the control circuitry selects a Demodulation Reference Signal (DMRS) mapping pattern from among a plurality of DMRS mapping patterns. The DMRS mapping patterns include a first DMRS mapping pattern with first DMRS resource elements to which first DMRSs in a first half of a subframe are mapped and second DMRS resource elements to which second DMRSs in a second half of the subframe are mapped. Also, in operation, the transmitter transmits downlink control information that includes a plurality of bits indicating the selected DMRS mapping pattern.

A mobile communications terminal comprising a radio frequency interface configured to operate at least at a first configuration, and a controller, wherein said controller is configured to determine that a reconfiguration of the radio frequency interface is to be performed, determine a timing of the reconfiguration and reconfigure said radio frequency interface to operate at a second configuration at the determined timing, wherein said controller is configured to determine said timing based on the type of reconfiguration to be made.

During device-to-device communication between two devices, a communication transmitted from a first UE to a second UE may not be reliably received by the second UE if the first UE is traveling at high speed. Therefore, a travel speed of a transmitting UE may be considered in determining a transmission configuration. According to an aspect, the UE may determine a travel speed of the UE. The UE may determine, based on the travel speed of the UE, a transmission configuration of the UE for device-to-device communication. The UE may transmit the device-to-device communication based on the transmission configuration.

Network-side and device-side methods and apparatuses improve transmit link adaptation for devices operating in a cellular network that have interference-canceling receivers. Own-cell link adaptation towards a device in a current transmission interval exploits a determined mapping between the interfering-signal cancelation efficiency of the device versus the interfering-signal transport format, in combination with actual knowledge of the transport format that will be used to make an interfering neighbor-cell transmission in the current transmission interval. For example, a serving radio node uses the known transport format of the interfering transmission, to accurately determine the expected cancellation efficiency for the device with respect to the interfering transmission, and uses the expected cancellation efficiency to obtain a more accurate estimate of the own-cell channel quality expected for the device in the current transmission interval. Link adaptation towards the device in the current transmission interval uses this more accurate estimate of own-cell channel quality.
