Abstract: The present disclosure discloses cache-based data transmission methods and apparatuses. The method is implemented as follows. An apparatus where a caching node is located reports a caching capability to a network side, and the caching node is configured to cache data. The network side sends a cache indicating parameter to the apparatus where the caching node is located, and maintains a data list. Wherein, the cache indicating parameter is configured to control the caching node to cache the data which has the property of high repetition probability and/or high cache utilization, and the data list is a list of the data cached in the caching node. When the caching node has cached data requested by a UE, the UE obtains the requested data from the caching node.

Abstract: The present disclosure provides several methods, user equipment (UEs) and base stations for transmitting uplink signals. After receiving uplink synchronization command information, the UE may transmit an uplink signal on at least one idle unlicensed cell. Besides, the UE may try to transmit the uplink signal on multiple uplink signal resources within an uplink signal transmission window. By using the present disclosure, transmission probability of uplink signals may be improved, and time delay of uplink synchronization may be shortened.

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.
