HARQ ACK/NACK BUNDLING IN DOWNLINK CARRIER AGGREGATION
摘要
There are described methods, devices and systems for bundling of HARQ feedback for a carrier aggregation. Bundling is performed based on one of: Frequency domain bundling; Differentiated bundling for different frequency bands (e.g. differentiated bundling for licensed and unlicensed carriers); differentiated bundling for primary carrier and secondary carriers; and DL CC group specific bundling configuration.
