摘要： A device resolves a collision between its transmission and a simultaneous transmission of another device. The device is configured to interrupt its transmission, determine a negotiation signal, and determine at least one available resource to occupy with the negotiation signal during a negotiation period. Further, the device is configured to transmit the negotiation signal on the at least one available resource and simultaneously receive a negotiation signal on another resource from at least one other device during the negotiation period. Then, the device is configured to decide, based on all negotiation signals, whether to retransmit the interrupted transmission after the negotiation period.

摘要： A radio frequency (RF) front end for wireless communications, in particular for use in a half duplex (HD) and/or full duplex (FD) transceiver. The RF front end is based on a quadrature balanced power amplifier (QBPA). The RF front end includes an antenna port for outputting a transmit signal to and receiving a receive signal from an antenna, and a receive port for outputting the receive signal to a signal processing section. Further, the QBPA is configured to receive a transmit input signal at a first port, receive a cancellation input signal at a fourth port, and receive the receive signal at a second port coupled to the antenna port.

摘要： An apparatus for band-limited frequency division multiplexing for uplink transmission to a base station or access point, particularly from an IoT device, comprises a signal modulator to transmit a signal over a set of contiguous equally spaced frequency sub-carriers ranging from a lowest frequency sub-carrier via intermediate sub-carriers to a highest frequency sub-carrier. The signal modulator contains a filter to apply asymmetric filtering over the range of the frequency sub-carriers, thereby to reduce a peak-to-average power ratio of the transmitted signal.
