Abstract: This application provides an uplink reference signal sending method and apparatus, a base station, and user equipment (UE). The method includes: configuring, by the base station, M pieces of uplink reference signal resource information for the UE; and sending, by the base station, the M pieces of uplink reference signal resource information to the UE, so that the UE sends uplink reference signals based on different uplink reference signal resource information with different beamforming gains. A path loss is compensated for by using a beamforming technology. In addition, the base station configures the M pieces of uplink reference signal resource information for the user equipment UE, so that the UE sends the uplink reference signals by using different relatively uplink reference signal resource information based on different beamforming gains. Therefore, uplink reference signal sending efficiency is improved.

Abstract: This application relates to the field of wireless communications technologies, and discloses a signal sending method. The method includes: mapping, onto a time frequency resource, a first signal that is in frequency domain and that corresponds to a subcarrier spacing parameter in a subcarrier spacing system parameter group, and generating a second signal that is in time domain and that corresponds to the first signal; and sending the second signal to a second network device. First signals corresponding to the different subcarrier spacing system parameters occupy a same quantity of subcarriers, and second signals corresponding to the different subcarrier spacing system parameters occupy a same time length T.

Abstract: This application discloses example information indication methods and related devices. In one example method, a terminal device receives first information used to instruct the terminal device to receive a first channel in a first time unit, and second information used to instruct the terminal device to receive a second channel in a second time unit. The terminal device receives the first channel based on the first information. When the first time unit is equal to the second time unit, the terminal device receives the second channel based on the first information, where the second information is a first indicator value. When the first time unit is not equal to the second time unit, the terminal device receives the second channel based on the second information where the second information is a second indicator value.

Abstract: This application provides a channel state information feedback method, user equipment, and a base station. A base station configures N first reference signal resources for UE, and sends the N first reference signal resources to the UE. The UE feeds back the CSI of the M first reference signal resources in a horizontal dimension and the M pieces of first reference signal resource indication information to the base station. This overcomes a disadvantage that only channel state information in a horizontal dimension is fed back in conventional channel estimation.
