1. A method performed by a communication device configured to perform sidelink communication, the method comprising:
obtaining a reference value used for determining a number of modulation symbols for transmission of second sidelink control information (SCI), based on:
a number of bits of the second SCI;
a number of cyclic redundancy check (CRC) bits for the second SCI;
a beta offset value in first SCI related to the second SCI;
an alpha value configured for a resource pool;
a number of symbols for physical sidelink shared channel (PSSCH) transmission; and
a number of resource elements (REs) for transmission of the second SCI in each symbol;
determining the number of modulation symbols for transmission of the second SCI, based on adding a gamma value to the reference value,
wherein the gamma value is a number of vacant REs in a resource block (RB) to which a last modulation symbol of the second SCI belongs; and
transmitting the second SCI on a PSSCH, based on the number of modulation symbols for transmission of the second SCI.
