Abstract: The present disclosure provides an uplink signal transmission method, user equipment (UE) and base station. When the UE transmits uplink signals in an unlicensed frequency band after receiving uplink synchronization command information, the UE transmits one or more uplink signals according to a predefined time or a time indicated by the base station. The UE determines mapping of an uplink signal according to the predefined time or the indicated time. When provided with the present disclosure, interference between signals of a same type or between signals of different types can be reduced and a signal transmission probability can be improved accordingly.

Abstract: Provided are a method for receiving, by a terminal, a scheduling signaling transmitted by a transmitting node; then, deciding, by the terminal, whether a gap is to be reserved between an uplink signal symbol and an uplink physical channel symbol, and determining a time-frequency resource mapping of an uplink signal and/or an uplink physical channel; or, deciding, by the terminal, whether a predefined signal is to be transmitted on a predefined time-frequency resource within an uplink signal symbol, and determining a time-frequency resource mapping of an uplink signal and/or an uplink physical channel; transmitting, by the terminal, the uplink physical channel and/or the uplink signal, or quitting scheduling and transmitting the uplink physical channel and/or the uplink signal. Thus, when an uplink signal is transmitted on the basis of an LBT, mutual hindrance between an uplink physical channel and an uplink detection signal is effectively reduced.

Abstract: The present disclosure provides a data transmission method. A UE receives CSI-RS configuration signaling from a base station, measuring and reporting CSI according to the CSI-RS configuration signaling. The UE receives scheduling signaling from the base station, and receives downlink data according to the scheduling signaling. The method provides a way of measuring and feeding back CSI with reduced CSI-RS overhead. The method can configure DMRS ports in a flexible manner. Therefore, performances of MU-MIMO can be optimized.
