    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: Embodiments of the present disclosure provide a method for transmitting data, including: sensing, by a first device, a scheduling assignment (SA) of another device; measuring a received power of the other device, and measuring a total received energy of a subframe/subband; determining a received power reference value and a total received energy reference value of the other device according to the SA; e selecting resources; and transmitting data using the selected resources. According to the method of the present disclosure, the performance of the method which avoids collision based on SA is improved, and measurement accuracy of the total received energy of the subband is increased. Thus, resource selection/re-selection can be performed better. As such, interferences between devices can be avoided effectively.

    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: A method for an uplink transmission of a user equipment (UE) in a wireless communication system and the UE are provided. The method includes receiving, from a base station (BS), control signaling; grouping physical downlink shared channels (PDSCHs) based on the control signaling; determining a hybrid automatic repeat request acknowledgement/negative acknowledgement (HARQ-ACK/NACK) codebook for each grouping of the PDSCHs; and transmitting HARQ-ACK/NACK information corresponding to the HARQ-ACK/NACK codebook. The UE includes a transceiver configured to receive control signaling from a BS; and a processor configured to: group PDSCHs based on the control signaling; and determine an HARQ-ACK/NACK codebook for each group of PDSCHs, wherein the transceiver is further configured to transmit HARQ-ACK/NACK information corresponding to the HARQ-ACK/NACK codebook.

    Abstract: The present disclosure provides a method for feeding back aperiodic CSI in a flexible TDD reconfiguration cell. The method includes a UE receiving information about signaling transmitted from an eNB to acquire locations of subframes corresponding to CH and CL, wherein CH and CL correspond to different subframe sets, respectively. The method also includes the UE detects UL DCI information carrying an aperiodic CSI request, on a CSI request subframe. The method also includes the UE feeds back aperiodic CSI specific to a corresponding CSI subframe set to the eNB, on a corresponding UL subframe. The embodiments of the present disclosure, according to another aspect, provide a terminal. According to the solutions disclosed in the present disclosure, the terminal acquires indication information of CSI subframe sets during feeding back the aperiodic CSI, by implicitly or explicitly defining the CSI subframe sets, so as to trigger aperiodic CSI feedback specific to CH and CL in a flexible TDD reconfiguration cell, thus improving the system performance.
