    摘要: It is described a method of operating a base station and a base station which uses a communication channel depending on channel state related information and time information e.g. a prediction time. In this way, problems due to outdating of the channel state related information may be overcome and a feedback overhead may be reduced. According to other embodiments, other parameters like a used prediction method, a prediction horizon, etc. are used to provide a better scenario adaption. Other embodiments relate to combined long term prediction and short term prediction and respective timing settings. Other embodiments relate to a method of operating a user equipment and a user equipment which is adapted for communicating the required time information between the base station and the user equipment.

    摘要: The present invention is concerned with different novel concepts for reducing latency in data transmission. These concepts may be exploited by a transceiver (30) configured to perform wireless data communication with a third party device (36) by aggregating time division duplex (TDD) carriers having different temporal distribution of uplink times and downlink times. These concepts may further be exploited by an apparatus configured to perform data transmission or reception via allocations of transmission resources of aggregated carriers (C1, C2, C3) in units of transmission time intervals (TTI) into which the aggregated carriers (C1, C2, C3) are subdivided, wherein the aggregated carriers (C1, C2, C3) are temporally subdivided into the transmission time intervals (TTI) in a temporal grid, respectively, wherein the aggregated carriers' grids are temporally mutually offset.
