Description

Method and device used in user equipment and base station for dynamic scheduling
Technical Field
The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus of a control channel in wireless communication used for dynamic scheduling.
Background
In an existing LTE (Long Term Evolution) system, for a Downlink subframe, a UE searches for corresponding DCI (Downlink Control Information) in the Downlink subframe. In consideration of Robustness (Robustness) and high coverage requirement of DCI transmission, a PDCCH (Physical Downlink Control Channel) or an EPDCCH (Enhanced Physical Downlink Control Channel) corresponding to the DCI is often transmitted in a Diversity (Diversity) or precoding Cycling (precoding Cycling) manner.
In future mobile communication systems, Beamforming (Beamforming) and Massive multiple antenna system (Massive-MIMO) are introduced. The control signaling is transmitted in a beamforming manner, and accordingly, the transmission manner of the control signaling and the corresponding Search Space (Search Space) are considered again.
Disclosure of Invention
A simple way to transmit control signaling is to indicate the direction or index of the transmit beam used for control signaling to the UE before the UE receives it. For example, control signaling is transmitted on two beams, respectively, and the base station informs the UE of this information before the UE performs Blind detection (Blind Decoding) on the control signaling. However, this method has a significant problem of adding additional signaling overhead, especially when the beam transmitting the control signaling is dynamically changed. Meanwhile, considering that the information needs to be received before receiving the control signaling, the information is often Non-UE-Specific (Non-UE-Specific) according to the characteristics of the existing LTE system, and the Non-UE-Specific information further brings additional overhead and implementation complexity of the physical layer control signaling.
The present application provides a solution to the above problems. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict. For example, embodiments and features in embodiments in the UE of the present application may be applied in a base station and vice versa.
