Abstract: The present disclosure relates to communication methods and devices. One example method includes determining that a downlink bandwidth belongs to one of N downlink bandwidth sets, where each downlink bandwidth set of the N downlink bandwidth sets corresponds to one first value and one second value, at least two first values corresponding to at least two downlink bandwidth sets of the N downlink bandwidth sets are different, each downlink bandwidth set of the N downlink bandwidth sets corresponds to a same second value, the second value is a common divisor of N first values corresponding to the N downlink bandwidth sets, determining that a quantity of resource blocks included in a first resource block group is a first value corresponding to the downlink bandwidth set to which the downlink bandwidth belongs, and determining that a quantity of resource blocks included in a precoding resource block group is the second value.

Abstract: Embodiments of this application provide a method for sending downlink control information, a terminal device, and a network device, and relate to the communications field, to resolve problems of low flexibility and low reliability of a system DCI configuration. The method includes: receiving 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 sending 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 sending the one codeword, and a 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 sending the one codeword.
