Transmission of hierarchical beamforming structures and beam instructions to improve device mobility and reduce network traffic overhead in new radio

摘要

The hierarchical beamforming architecture assists in reducing the network traffic overhead for transmitting beam instructions (information) and facilitates beam tracking between the base station and the mobile device during downlink communications Efficient transmit configuration instructions can be made possible.The downlink control information (DCI) may be extended to convey / transmit a beam / QCL instruction to a control resource set (coreset) for monitoring the next instance of the physical control channel.An error resistant design technique may be used to increase the degree of freedom for gc-pdcch / PDCCH beam / QCL instructions and further improve the mobility of the device while reducing its latency.For example:Select DCI (e.g.The aggregation level of the dc-pdcch / PDCCH beam directive DCI changed can be increasedSuch selective DCI transmission isMay be limited to a specific (specified) aggregation levelIf discontinuous transmission (DTX) is receivedBase stationBoth the old beam / QCL command and the new beam / QCL instruction may be transmitted.
