UPLINK CONTROL INFORMATION SIGNALING IN INTER-SITE DOWNLINK CARRIER AGGREGATION SCENARIOS

摘要

There are provided measures for uplink control information signaling in inter-site downlink carrier aggregation scenarios. Such measures exemplarily comprise obtaining uplink transmission resources for an uplink control information transmission on said primary carrier, deriving a receiving timing for said uplink control information transmission, detecting said uplink control information transmission on said primary carrier based on said uplink transmission resources and said receiving timing, and decoding uplink control information from said uplink control information transmission.
