TRANSMISSION OF UPLINK PHYSICAL LAYER CONTROL INFORMATION

摘要

To offload some uplink control information sent on a physical uplink control channel to a secondary cell, configuration information indicating a secondary cell as an indicated cell via which uplink control information may be transmitted is sent to a user apparatus, and when the user apparatus receives one or more downlink assignments triggering sending of uplink control information on a physical uplink control channel, the user apparatus uses a physical uplink control channel on the primary cell if the one or more downlink assignments were received via the primary cell, or primary cell associated cells; otherwise a physical uplink control channel on the indicated cell is used.
