Title:
METHODS AND DEVICES FOR LINK ADAPTATION UNDER CONDITIONS OF INTERMITTENT INTERFERENCE IN WIRELESS COMMUNICATION SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2018/010542
Kind Code:
A1
Abstract:
A method for assisting link adaptation of a downlink between a eNB (101) and a User Equipment (103) in an LTE system operating in unlicensed spectrum which is subject to intermittent interference, relies on the UE sending to the eNB additional information included in channel quality indicator (CQI) reports notifying the eNB of the duty cycle of the interferer. Based on the information contained in this modified CQI report the eNB can choose to use a higher order modulation coding scheme (MCS) which will provide a higher throughput but will necessitate frequent retransmissions or a lower order MCS which will not require frequent retransmissions but will have the disadvantage of a lower throughput.
