Title:
METHOD AND DEVICE FOR TRANSMITTING UPLINK FEEDBACK INFORMATION
Document Type and Number:
WIPO Patent Application WO/2017/152645
Kind Code:
A1
Abstract:
The present invention provides a method and device for transmitting uplink feedback information. The method comprises: a terminal receives configuration information sent by a licensed assisted access master cell group (LAA-MCG) side of a network side; the terminal receives a downlink data block from an unlicensed carrier of an LAA-SCG side of the network side, and sends UCI corresponding to the downlink data block upstream to the network side over one or multiple uplink candidate sub-frames of the LAA-MCG side. The invention solves the problem that the downlink data transmission performance of an LAA-SCG side is affected because a secondary base station LAA-SeNB cannot obtain auxiliary UCI by means of a licensed carrier in time, and improves the downlink data transmission efficiency of an LTE system over an unlicensed carrier.
