The present disclosure provides a full duplex communication method implemented by a Radio Base Station (RBS) supporting Time Division Duplex (TDD) scheme and the associated RBS. The method comprises configuring a first logic cell and a second logic cell for the RBS by specifying a first downlink/uplink (DL/UL) configuration corresponding to the first logic cell and a second, different DL/UL configuration corresponding to the second logic cell. The method also comprises transmitting a first wireless signal to a first UE associated with one of the first and the second logic cells and receiving a second wireless signal from a second UE associated with the other of the first and the second logic cells simultaneously in a subframe, which is allocated for DL communication according to one of the first and the second DL/UL configurations corresponding to the one of the first and the second logic cells and is allocated for UL communication according to the other of the first and the second DL/UL configurations corresponding to the other of the first and the second logic cells. Self-interference suppression is performed to suppress interference from the transmission of the first wireless signal to the reception of the second wireless signal.

Full duplex communication method and associated radio base station

Example embodiments presented herein are directed towards methods for handling uplink-to-downlink interference between a first UE served by a first BS and a second UE served by a second BS, the first BS and the second BS being with full-duplex mode. According to the methods, the first BS receives from the first UE information about a first received signal quality associated with the first BS and a second received signal quality associated with the second BS. The first BS generates a full-duplex interference list associated with the second BS by putting the first UE into the full-duplex interference list if a difference between the first received signal quality and the second received signal quality is smaller than a threshold. Example embodiments are also towards methods for scheduling downlink reception and methods for scheduling uplink transmission.

The present disclosure provides a device () of crest factor reduction for a multi-carrier signal. The device () includes: a peak detector () adapted to receive a sampled representation of the multi-carrier signal, detect a peak from the sampled representation and obtain a value and a time domain location of a cancellation peak for cancelling the peak; a plurality of peak cancellation signal generators () each corresponding to a carrier of the multi-carrier signal and adapted to generate a peak cancellation signal within a frequency band of its corresponding carrier based on the value and time domain location of the cancellation peak; and a subtractor () adapted to subtract the peak cancellation signals from the sampled representation after being delayed. The present disclosure also provides another device of crest factor reduction, a multi-stage crest factor reduction circuit and a peak detector.
