-the name of the invention of the original application: user equipment used for dynamic scheduling, method and device in base station

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 for a control channel in wireless communication used for dynamic scheduling.

Background

In a conventional LTE (Long Term Evolution ) system, for one downlink subframe, a UE searches for corresponding DCI (Downlink Control Information ) in the downlink subframe. In view of Robustness (Robustness) and high coverage requirements of DCI transmission, PDCCH (Physical Downlink Control Channel ) or EPDCCH (Enhanced Physical Downlink Control Channel, enhanced physical downlink control channel) corresponding to DCI is often transmitted by means of Diversity (Diversity) or precoding Cycling (precoding).

In future mobile communication systems, beamforming (Beamforming) and the introduction of Massive multi-antenna systems (Massive-MIMO) are being used. The control signaling is transmitted in a beam forming manner, and accordingly, the transmission manner of the control signaling and the corresponding Search Space (Search Space) are reconsidered.

Disclosure of Invention

One simple way to transmit control signaling is to indicate the UE with a direction or index of the transmit beam used for control signaling before the UE receives it. For example, the control signaling is transmitted on two beams, respectively, and the base station tells the UE about this information before the UE performs Blind detection (Blind Decoding) on the control signaling. However, this approach has a significant problem in that it adds additional signaling overhead, particularly when the beam on which the control signaling is transmitted is dynamically changing. Meanwhile, considering that the information needs to be received before the control signaling is received, the information is often Non-UE-Specific (Non UE-Specific) and the Non-UE-Specific information further brings additional overhead and implementation complexity of the physical layer control signaling due to the characteristics of the existing LTE system.

The present application provides a solution to the above-mentioned problems. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other.
