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.
Claims30
A method comprising:
- determining a downlink control information format of downlink control information, the downlink control information scheduling a data transmission;
- determining, based on the downlink control information format, a quantity of resource elements per physical resource block (PRS) carrying a demodulation reference signal (DMRS) of the data transmission;
- and
- determining a transport block size (TBS) used for the data transmission based on the quantity of resource elements determined.
An apparatus comprising:
- at least one processor, configured to:
- determine a downlink control information format of downlink control information, the downlink control information scheduling a data transmission;
- determine, based on the downlink control information format, a quantity of resource elements per physical resource block carrying a demodulation reference signal (DMRS) of the data transmission;
- and
- determine a transport block size (TBS) used for the data transmission based on the quantity of resource elements determined.
The apparatus according to claim ii, wherein the at least one processor is further configured to obtain a configuration type of the DMRS, a quantity of symbols occupied by the DMRS, a quantity of symbols occupied by a transport block of the data transmission, a position of a symbol occupied by the transport block, and a quantity of additional DMRSs;
- and wherein determining the quantity of resource elements comprises determining the quantity of resource elements based on the downlink control information format, the configuration type of the DMRS, the quantity of symbols occupied by the DMRS, the quantity of symbols occupied by the transport block, the position of the symbol occupied by the transport block, and the quantity of the additional DMRSs, and wherein the downlink control information format is DCI format 0_0 or DCI format 1_0, the configuration type of the DMRS is DMRS configuration type 1, the quantity of symbols occupied by the DMRS is 1, and the quantity of the additional DMRSs is 0, 1, or 2.
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 format of downlink control information, the downlink control information scheduling a data transmission
- determining, based on the downlink control information format, a quantity of resource elements per physical resource block carrying a demodulation reference signal (DMRS) of the data transmission;
- and
- determining a transport block size (TBS) used for the data transmission based on the quantity of resource elements determined.
