21 Claims

1. A method, comprising:

determining, by a terminal device, a transport block size of a data channel based on a quantity of available resource elements N_RE′ of the data channel in a physical resource block, wherein

N_RE′=N_SC^RB(N_syml^sh−l_α)−N_DMRS^PRB−N_oh^PRB,

N_syml^sh=N_syml−2,

N_symlindicates a quantity of symbols used for sidelink communication in a slot,

N_SC^RB=12 indicates a quantity of subcarriers in the physical resource block is 12,

N_DMRS^PRBindicates an overhead of a demodulation reference signal on an encoded symbol in the physical resource block,

N_oh^PRBis configured by a higher layer, and

l_α is determined based on a configured period of a physical sidelink feedback channel.
