METHOD FOR SENDING DOWNLINK CONTROL INFORMATION, TERMINAL DEVICE, AND NETWORK DEVICE
First Claim
1. A method for receiving downlink data, the method comprising:
- receiving, by an apparatus, downlink control information (DCI) for scheduling downlink data to be transmitted as one codeword, wherein the DCI comprises a value of a set of values each indicating a corresponding quantity of layers of the one codeword and one or more antenna ports used for demodulating the one codeword, and wherein the set of values comprises;
a first value indicating that the quantity of layers of the one codeword is 2, and a first antenna port and a second antenna port are used for demodulating the one codeword, anda second value indicating that the quantity of layers of the one codeword is 2 and a third antenna port and a fourth antenna port are used for demodulating sending the one codeword;
determining, by the apparatus, a quantity of layers and one or more antenna ports indicated by the value; and
receiving, by the apparatus, the downlink data transmitted as the one codeword based on the determined quantity of layers and the determined one or more antenna ports.
