    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides a method of measuring interference and a corresponding device. The method of measuring interference includes: receiving a downlink reference signal from abase station; based on a received downlink reference signal of a first category, acquiring interference strength information of co-channel interference or self-interference caused by a user equipment (UE), which performs uplink transmission on a time frequency resource where the received downlink reference signal of the first category is transmitted, to a current user equipment, or information for the base station to acquire the interference strength information of the co-channel interference or the self-interference; and reporting the acquired interference strength information or the acquired information for the base station to acquire the interference strength information to the base station, wherein the downlink reference signal of the first category is: a downlink reference signal transmitted on a time frequency resource with scheduled uplink transmission. According to the method of measuring interference and the corresponding device, interference strength of co-channel interference between UEs or self-interference of a user equipment can be measured accurately. The present disclosure provides a method and apparatus for a first terminal to transmit information on demodulation failure to a base station in a wireless communication system, and a method and apparatus for a base station to schedule uplink transmission based on the fed back information on demodulation failure. 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 present 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). Example embodiments of the present disclosure relate to the field of wireless communication technologies, and for example, to a method for determining a timing relationship, including: receiving a timing relationship set indication indicating a timing relationship set for use at a User Equipment (UE); determining the timing relationship set based on the timing relationship set indication; receiving timing relationship indication information indicating a timing relationship for use at the UE; and determining the timing relationship for use at the UE based on the timing relationship set and the timing relationship indication information. The disclosure implements a method and apparatus for dynamically changing a timing relationship set, saves power consumption of the UE, and ensures timely data transmission.
