The method for the first terminal includes: receiving and demodulating data from the base station; determining at least one demodulation failure reason respectively associated with at least one second terminal causing inter-terminal interference to the first terminal, when demodulation of the data fails; generating information on demodulation failure based on the determined at least one demodulation failure reason; and transmitting the information on demodulation failure to the base station. The application relates to a method, a base station (BS), a user equipment (UE) and a system thereof for channel switching. The method includes: receiving, from the UE, information indicating that the UE has a full-duplex communication capability; transmitting, to the UE, control signaling notifying the UE to activate the full-duplex communication capability; and scheduling full-duplex transmission for the UE after the UE completes initialization of a self-interference cancellation module, wherein, the base station further configures a full-duplex mode timer and notifies the UE of configuration of the full-duplex mode timer. The present disclosure provides a base station, an apparatus and operation methods thereof for performing interference processing in a wireless communication system. The base station is configured to allocate resources for a plurality of apparatuses communicating with the base station based on a level of inter-apparatus interference among the plurality of apparatuses; and to indicate the allocated resources to the plurality of apparatuses. The apparatus is configured to acquire, from a base station, resources allocated for the apparatus by the base station based on a level of inter-apparatus interference among a plurality of apparatuses communicating with the base station; and to communicate based on the allocated resources.

    Abstract: The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). The disclosure provides a remote interference management method, a gNB, an electronic device, a readable storage medium, and a base station for performing inter-base station interference coordination. The method includes steps of: determining, by a gNB, a mapping relationship between a gNB set ID and a RIM-RS according to received configuration information; transmitting, by the gNB, the RIM-RS according to the allocated gNB set ID and the mapping relationship; and/or performing RIM-RS detection, by the gNB, determining gNB set ID information through the detected RIM-RS according to the mapping relationship, and reporting the determined gNB set ID information. The present disclosure determines the mapping relationship between the gNB set ID and the RIM-RS according to the received configuration information, and further transmits and/or detects the RIM-RS based on the mapping relationship, thus simplifying signaling interaction information and improving the communication flexibility of the RIM-RS with multiple functions.

    Abstract: The present disclosure provides a method and an apparatus for self-interference cancellation, a terminal and a base station are disclosed. The method includes truncating a signal based on a detection window, where the signal comprises a receive signal and a self-interference signal which is associated with a transmit signal, and a length of the detection window is less than a symbol length, performing self-interference channel estimation to obtain an estimation of a self-interference channel, based on the truncated signal and a first reference signal which is carried by the transmit signal and used for self-interference channel estimation, where the first reference signal has a comb structure in frequency domain, and performing self-interference cancellation based on the transmit signal and the estimation of the self-interference channel. The method can reduce the influence on the accuracy of self-interference channel estimation due to inter-symbol interference caused by timing misalignment. And, the present disclosure provides a method and device for transmitting a first physical signal in a wireless communication system, the method including: mapping a sequence of each antenna port for the first physical signal to a same plurality of subcarriers on same one or more OFDM symbols based on a frequency-domain mapping pattern of the first physical signal; and transmitting the first physical signal.
