Transmission of uplink control information in wireless systems

Abstract:

Future LTE systems will support massive carrier aggregation that necessitates transmission of a large number of acknowledgement signals (HARQ-ACKs) in response to downlink data transmitted over multiple component carriers. Described herein are methods for HARQ-ACK transmission over the PUCCH (physical uplink control channel) that relate to HARQ-ACK codebook size adaptation, DAI (downlink assignment index) design options, HARQ-ACK bit channel coding and interleaving, and, frequency hopping configuration for a new PUCCH format.
