1. A first device comprising:
at least one processor; and
at least one memory including computer program codes;
the at least one memory and the computer program codes are configured to, with the at least one processor, cause the first device to:
determine bit reduction is to be performed on a frequency domain resource allocation;
determine that bit reduction is performed after transmitting a physical random access channel (PRACH) or a random access preamble on a cell;
receive, at the first device and from a second device, control information comprising an indication of resources allocated to the first device, wherein bit reduction has been performed on the indication, wherein the first device comprises a terminal device and the second device comprises a network device;
determine, an offset associated with the bit reduction, wherein the first device is caused to determine the offset by:
obtaining an Original number of bits in the control information for a bandwidth part (BWP) of N resource blocks (RB), wherein btot is the Original number of bits for the BWP of size NBWP;
obtaining a reduced number of bits (bred) in the control information,
wherein the reduced number of bits is predetermined at the first device or received from the second device; and
determining the offset based on the Original number of bits and the reduced number of bits:
Offset=N tot−2b tot −b red;
determine the resources allocated to the first device based on the offset and the indication, wherein the first device is caused to determine the resources allocated to the first device by:
updating the indication with the offset; and
determining the resources allocated to the first device based on the updated indication;
wherein the indication extracted is a unique resource indication value (RIV) and the updated RIV′ is represented as RIV+Offset; and
determine a start position of the resources based on the updated indication.
