Abstract: An information receiving method and apparatus, and an information sending method and apparatus are disclosed. The information receiving method includes: A terminal device receives first configuration information from a network device, where the first configuration information carries precoding indication information of each resource unit of N resource units allocated to the terminal device; and the terminal device performs precoding processing on uplink data carried on each resource unit by a precoding matrix corresponding to the precoding indication information of each resource unit, based on the first configuration information. In this method, the terminal device determines, based on the precoding indication information, a quantity N and sizes of the resource units obtained through division.

Abstract: This application provides a communication method and apparatus. The method includes: A terminal device receives an MCS index value from a network device, and determines, in an MCS index table, a modulation method and a target bit rate that correspond to the MCS index value, where a maximum target bit rate corresponding to a π/2 BPSK modulation method in the MCS index table is greater than a first threshold, so that the terminal device can achieve higher spectral efficiency when performing uplink transmission by using the π/2 BPSK modulation method, thereby improving uplink performance.

Abstract: This application relates to the field of communications technologies, and discloses a method and an apparatus for indicating a number of repetitions, so that a configuration of a number of repetitions of an SRS and/or a PUSCH is more adaptive to a channel change. The method includes: A network device sends DCI to a terminal device, where the DCI includes first indication information, and the first indication information indicates a number of repetitions of an SRS and/or a PUSCH. Because the DCI has a faster update process than RRC signaling, and overheads are smaller than those of the RRC signaling, the network side device may flexibly configure the number of repetitions of the SRS and/or the PUSCH by using the DCI, to better adapt to the channel change, and further improve a channel estimation capability and signal demodulation performance.
