- -application number of the original application: 201780083600.0

The invention of the original application is named: method and device used for multi-antenna transmission in user equipment and base station

Technical Field

The present invention relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a method and apparatus for multi-antenna transmission.

Background

In a conventional LTE (Long Term Evolution) system, a base station configures, through RRC (Radio Resource Control) signaling, a plurality of Information related to Physical layer Transmission for a UE (User Equipment), for example, TM (Transmission Mode), DMRS (Demodulation Reference Signal) configuration, SRS (Sounding Reference Signal) configuration, PUCCH (Physical Uplink Control Channel) configuration, CSI-RS (Channel State Information-Reference Signal) configuration, TPC (Transmission Power Control) configuration, and the like. The information is sent to the user equipment through a signaling of UE-Specific or Cell-Specific, and when the user equipment has RRC Reestablishment (Reestablishment), the information is reconfigured. Meanwhile, part of the physical layer transmission not only requires RRC signaling to configure a plurality of candidate Information, but also requires DCI (Downlink Control Information) signaling to indicate one candidate Information from the configured plurality of candidate Information to complete a final operation, for example, reporting of a-CSI (Aperiodic CSI) in a CA (Carrier Aggregation) scenario.

In future mobile communication systems, due to the introduction of Beamforming (Beamforming) and Massive-MIMO (Massive Multiple-Input Multiple-Output) systems, the above mechanisms need to be considered again.

Disclosure of Invention

In future mobile communication systems, a base station transmits a downlink control channel and a downlink data channel on a plurality of transmit beams (Tx-Beam). At the same time, the UE will also detect the downlink control channel and the downlink data channel on multiple receive beams (Rx-Beam). Due to the mobility, rotation and Blocking of transmission path (Blocking) of the UE, the UE may switch between multiple Tx-beams or multiple Rx-beams to obtain better reception quality, especially control signaling. For such a scenario, the configuration of RRC signaling would be problematic. One solution is to configure different RRC signaling for different beams, but an obvious disadvantage of this method is that the RRC configuration cycle is much slower than the switching between beams, so that in one RRC cycle, different beams can only operate with fixed configuration parameters and cannot be configured flexibly, thereby affecting the performance gain caused by beamforming.

The present invention 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.
