    Abstract: The present disclosure provides an uplink transmission method, and a corresponding user equipment, base station and computer readable medium. A method for an uplink data transmission includes: determining a transmission occasion for an uplink transmission and a Hybrid Automatic Repeat Request, HARQ, process ID corresponding to the transmission occasion; determining an antenna port according to a correspondence between antenna ports and HARQ process IDs and/or a correspondence between antenna ports and transmission occasions; and transmitting, by the antenna port, uplink data corresponding to the HARQ process ID and a pilot signal corresponding to the uplink data. By establishing the correspondence between the antenna ports and the HARQ process IDs or the transmission occasion, the base station determines the antenna port when detecting the uplink transmission, so that the HARQ process ID corresponding to the uplink transmission may be determined.

    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.

    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. Embodiments of the present invention provide a method for RACH re-attempt, a user equipment and a base station. The method comprises the steps of: by a base station, determining system configuration information and transmitting the system configuration information to a user equipment; and then, by the user equipment, transmitting a preamble sequence to perform random access, and if the random access is failed, performing RACH attempt according to the received RACH re-attempt configuration information to perform random access until a preset decision condition is satisfied. The embodiment of the present invention is used for RACH re-attempt when random access fails.
