10. A transmitting device for transmitting control information in a wireless communication system, the transmitting device comprising:
a transceiver; and
at least one processor connected to the transceiver and configured to:
add cyclic redundancy check (CRC) bits to the control information;
mask the CRC bits, except for first 3 bits of the CRC bits, with an identifier of a receiving user equipment (UE) and an identifier of the transmitting device; and
transmit the control information to the receiving UE,
wherein the control information includes downlink control information (DCI) or sidelink control information (SCI), and
wherein the at least one processor is configured to mask the CRC bits, except for the first 3 bits of the CRC bits, by:
masking at least one bit of the CRC bits with the identifier of the receiving UE, and
masking one or more remaining bits, other than the at least one bit of the CRC bits, with a part of the identifier of the transmitting device.
 
11. A receiving user equipment (UE) for receiving control information in a wireless communication system, the receiving UE comprising:
a transceiver; and
at least one processor connected to the transceiver and configured to:
receive, from a transmitting device, the control information appended with cyclic redundancy check (CRC) bits; and
decode the control information,
wherein the CRC bits, except for first 3 bits of the CRC bits, are masked with an identifier of the receiving UE and an identifier of the transmitting device,
wherein the control information includes downlink control information (DCI) or sidelink control information (SCI),
wherein at least one bit of the CRC bits, except for the first 3 bits of the CRC bits, is masked with the identifier of the receiving UE, and
wherein one or more remaining bits, other than the at least one bit of the CRC bits, are masked with a part of the identifier of the transmitting device.
