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: The present invention provides a control information transmission resource determining method in a D2D communication. In this method, a location of a subframe used for a SA transmission is determined in a SA resource pool by a TRP. In the subframe, a frequency domain resource used for the SA transmission occupies a part of symbols or PRBs in the entire subframe, and a location of the frequency domain resource is determined by a central control node assigning way, a randomly selecting way, a resource-hopping way or a mapping way between a time domain resource and a frequency domain resource. According to the method above, data transmission delay can be effectively reduced, data transmission reliability can be ensured, and V2X communication requirements can be achieved by small changes in a current system.

Abstract: An apparatus and method for feeding back hybrid automatic repeat request-acknowledgement (HARQ-ACK) information are provided. The apparatus and method include user equipment (UE) that first receives a downlink grant (DL-GRANT) which schedules downlink HARQ transmission in a time-frequency bundling window corresponding to an uplink subframe used for feeding back HARQ-ACK, obtains a DL downlink assignment index (DL DAI) in the DL-GRANT, and determines a mapping value of each DL DAI. Then, according to the mapping value of the corresponding DL DAI, the HARQ-ACK bit of each HARQ feedback unit is mapped to a corresponding bit of a feedback bit sequence. According to the method and apparatus provided by the present disclosure, useless HARQ-ACK bits may be effectively removed, and efficiency for feeding back HARQ-ACK may be increased. As such, a downlink peak rate of a UE is ensured.
