Abstract: Example resource dynamic indication methods and an apparatus are described. One example method includes determining, by a first node based on first indication information sent by a second node or a donor node, semi-static resource configuration on first resources corresponding to D carriers and second resources corresponding to F cells. The first node determines, based on second indication information sent by the second node or the donor node, an availability status of an available resource in the first resources corresponding to the D carriers and an availability status of a dynamic resource in the second resources corresponding to the F cells.

Abstract: This application discloses example power control methods and apparatuses. One example method includes receiving, by a first node, first information sent by a second node, where the first information is used to determine a first transmit power, where the first transmit power is a power used when the first node sends downlink information to the second node through a first link, where the first link is a link between the first node and the second node, and where the first node is an upper-level device of the second node. The first node can then determine the first transmit power based on the first information.

Abstract: Embodiments of this application provide a communication method and an apparatus. A correspondence between a plurality of MCS indexes and a plurality of modulation schemes is provided to achieve flexible selection of a modulation scheme. In the correspondence, at least one MCS index of the plurality of MCS indexes corresponds to a set modulation schemes which comprises π/2 binary phase shift keying (π/2-BPSK) modulation and quadrature phase shift keying (QPSK) modulation. A first communication device receives a target modulation and coding scheme (MCS) index from a second communication device, determines a target modulation scheme corresponding to the target index number based on the correspondence, and performs communication with the second communication device based on the target modulation scheme.

Abstract: This application discloses a signal transmission method and apparatus, to implement signal transmission by using a multi-stream DFT-s-OFDM waveform. The method includes: precoding N streams of signals based on a first codebook before sending, to obtain N1 precoded signals, where a quantity of non-zero elements in each row of the first codebook is 1, the first codebook causes a phase difference between two of the N streams of signals, and N and N1 are integers greater than 1; and sending the N1 precoded signals. A transmitting end introduces a phase offset between two transmit antenna ports in a precoding process, so that equivalent inter-stream interference is optimal after channel equalization is performed at a receiving end, to improve demodulation performance of the receiving end.
