SYSTEM AND METHOD FOR TRANSMITTING CONTROL INFORMATION IN OVERHEAD IN MOBILE COMMUNICATION NETWORK Russian patent published in 2015 - IPC H04W52/00 H04L1/16 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to a method of operating a wireless communication terminal. The method includes receiving one or more downlink control messages, each containing scheduling information, which schedules a wireless terminal to receive a downlink transmission on either a primary carrier or a secondary carrier. The method also includes determining, for each of the downlink control messages, whether that message includes scheduling information for the primary carrier or for the secondary carrier. Additionally, the method includes selecting a format for an uplink control message based on whether any of the downlink control messages includes scheduling information for the secondary carrier, generating an uplink control message based on the selected format and transmitting the uplink control message to the base station.

EFFECT: finding an efficient scheme for transmitting information on component carrier scheduling to improve throughput in networks which support carrier aggregation.
