Abstract
A method for obtaining a quantity of resource elements in a communication process, comprising: determines a downlink control information format of downlink control information, obtains, based on the downlink control information format, a quantity of resource elements occupied by a demodulation reference signal (DMRS); and determines a size of transport block (TBS) based on the quantity of resource elements occupied by the DMRS.
Claims24
A method comprising:
- determining a downlink control information (DCI) format of DCI, the DCI scheduling a data transmission;
- determining, based on the DCI format and a predefined correspondence, a quantity of resource elements per physical resource block (PRB) of a demodulation reference signal (DMRS), wherein the DCI format is DCI format 0_0 or DCI format 1_0, and the predefined correspondence comprises a correspondence between the DCI format and the quantity of resource elements per PRB of the DMRS;
- and
- determining a transport block size (TBS) used for the data transmission based on the quantity of resource elements that is determined.
An apparatus comprising:
- at least one processor, configured to:
- determine a downlink control information (DCI) format of DCI, the DCI scheduling a data transmission;
- determine, based on the DCI format and a predefined correspondence, a quantity of resource elements per physical resource block (PRB) of a demodulation reference signal (DMRS), wherein the DCI format is DCI format 0_0 or DCI format 1_0, and the predefined correspondence comprises a correspondence between the DCI format and the quantity of resource elements per PRB of the DMRS;
- and
- determine a transport block size (TBS) used for the data transmission based on the quantity of resource elements that is determined.
A non-transitory computer-readable media storing computer instructions, that when executed by one or more processors, cause the one or more processors to perform steps of:
- determining a downlink control information (DCI) format of DCI, the DCI scheduling a data transmission;
- determining, based on the DCI format and a predefined correspondence, a quantity of resource elements per physical resource block (PRB) of a demodulation reference signal (DMRS), wherein the DCI format is DCI format 00 or DCI format 10, and the predefined correspondence comprises a correspondence between the DCI format and the quantity of resource elements per PRB of the DMRS;
- and
- determining a transport block size (TBS) used for the data transmission based on the quantity of resource elements that is determined.
