8. A communication apparatus, comprising:
a processor configured to:
determine, based on a quantity of resource elements (REs) that are in a first time-frequency resource and that are used to transmit first information, a quantity of REs that are in the first time-frequency resource and that are used to transmit data, wherein the first time-frequency resource comprises a first time unit in time domain and comprises a data channel resource in frequency domain, and wherein the first information comprises at least one of a control channel, a control channel demodulation pilot, a data channel demodulation pilot, second-stage control information, a phase tracking reference signal (PTRS), or a channel state information reference signal (CSI-RS);
wherein the first information comprises the second-stage control information, and wherein a quantity NohSCI2RE of REs that are in the first time-frequency resource and that are used to transmit the second-stage control information satisfies:

OG Complex Work Unit Math
wherein OSCI2 represents a valid payload size of the second-stage control information, wherein LSCI2 represents a cyclic redundancy check (CRC) bit length of the second-stage control information, wherein R represents a bit rate of a data channel, Q represents a modulation order of the control channel, wherein β represents a scale factor that is of a resource for the second-stage control information and that is indicated by first control information, wherein α represents the scale factor of the resource used to transmit the second-stage control information, wherein γ is an integer and represents a quantity of REs that is defined to satisfy that the second-stage control information occupies an integer quantity of physical resource block (PRBs), wherein Nsymlsh″=lengthSLsymbols−NsymboldPSFCH−2, wherein lengthSLsymbols is a quantity of symbols of a sidelink communication slot, NsymbolPSFCH is a quantity of symbols occupied by a PSFCH, wherein NsymbolPSFCH=0 or NsymbolPSFCH=3, MscPSCCH(l) is a quantity of subcarriers in a data channel scheduling bandwidth, and wherein MscPSCCH(l) is a quantity that is of subcarriers in a control channel bandwidth on symbol l and that is configured by higher layer RRC, and wherein Q and β are integers.
