Claim of US Patent No. 11,071,096


1. A method of transmitting uplink control information in a carrier aggregation environment, the method comprising:at a user equipment device (UE):determining n pieces of Hybrid Automatic Repeat request (HARQ) response data, wherein the n pieces of HARQ response data are responsive to data channel receptions through n respective downlink component carriers, wherein respective numbers of bits of respective pieces of HARQ response data are based on a respective transmission scheme of the respective downlink component carrier, wherein the respective pieces of HARQ response data of the n pieces of HARQ response data are configured as:when a respective downlink component carrier corresponding to the respective piece of HARQ response data is configured for a transmission scheme corresponding to one codeword, the respective piece of HARQ response data consists of 1 bit; and
when the respective downlink component carrier corresponding to the respective piece of HARQ response data is configured for a transmission scheme corresponding to two codewords, the respective piece of HARQ response data consists of 2 bits;

determining k bits of integrated response data by combining the n pieces of HARQ response data in serial according to a sequence preset for downlink component carriers;
performing a coding of the integrated response data to produce encoded integrated response data; and
transmitting the encoded integrated response data to a base station.
