Method and apparatus for transmitting uplink control information

摘要

A method for transmitting uplink control information and a wireless device are provided. The wireless device masks the cyclic redundancy check (CRC) of a first piece of uplink control information with a masking sequence related to a second piece uplink control information and transmits the masked first piece of uplink control information to an uplink channel.

主权项

1. A method for transmitting uplink control information in a wireless communication system, the method performed by a wireless device and comprising:
determining, by the wireless device, whether to multiplex first uplink control information with second uplink control information; generating, by the wireless device, a masking sequence based on the determination; masking, by the wireless device, a cyclic redundancy check (CRC) of the first uplink control information with the masking sequence; and transmitting, by the wireless device, the masked first uplink control information through an uplink channel, wherein the first uplink control information includes channel state information (CSI), and the second uplink control information includes a hybrid automatic repeat request (HARQ) positive-acknowledgement (ACK)/negative-acknowledgement (NACK), and wherein the masking sequence indicates the HARQ ACK/NACK transmission state for at least one serving cell.
