Abstract: Disclosed are an uplink transmission resource scheduling method and device, and an uplink transmission method and device, which are used for reserving an uplink transmission resource on an unlicensed carrier, enabling a user equipment (UE) not to transmit an uplink signal on the reserved resource and avoiding a case in which the scheduled UE cannot access a channel, and can realize time division multiplexing of uplink transmission resources on the unlicensed carrier. An uplink transmission resource scheduling method provided by the present application comprises: a base station determines a reserved resource in an uplink subframe, the reserved resource being a transmission resource on an unlicensed carrier; and the base station sends a notification about the reserved resource in the uplink subframe to a UE.

Abstract: A UCI transmission method, a UCI reception method, a terminal and a base station are provided. The UCI transmission method includes, when a collision is present between different types of UCIs with a first TTI length and/or a collision is present between a UCI with the first TTI length and a UCI with a second TTI length, transmitting the UCIs with the collision to a base station simultaneously using a second sPUCCH format on a predetermined sPUCCH resource corresponding to the second sPUCCH format, or determining a transmission scheme for the UCIs with the collision in accordance with a sPUCCH format adopted by the UCI with the first TTI length.

Abstract: Disclosed in the present application are a method and device for feeding back downlink data. When a processing duration of an UE is shortened, feedback timing information for feeding back downlink data may be adaptively changed. The method comprises: determining a processing capability of an UE, the processing capability referring to a processing duration that the UE takes to process the received downlink data to determine whether said downlink data needs to be retransmitted; according to the determined processing capability, determining the feedback timing information of the UE feeding back the downlink data.
