Abstract: Embodiments of this application disclose a resource allocation method, a base station, and a terminal. The method includes: A base station sends a configuration message to a terminal, where the configuration message is used to configure, for the terminal, a random access channel RACH resource used in a channel occupancy time COT. The base station receives a random access request that is sent by the terminal based on the RACH resource allocated by using the configuration message. According to embodiments of this application, a random access latency of the terminal can be reduced.

Abstract: A method and apparatus for precoding matrix indicator feedback reduce a quantity of bits in the feedback. In the method, a terminal device receive a reference signal from a base station, determines a precoding matrix W in a precoding matrix set corresponding to a rank indication. W satisfies W=W1×W2×W3, W1, W2 and W3 and matrices and respectively corresponding to a first, second and third precoding matrix indicator. None of W1, W2, and W3 is an identity matrix, and the 2M columns in W1 comprise every column in W1×W2. The terminal device transmits the rank indication, the first precoding matrix indicator, the second precoding matrix indicator, and the third precoding matrix indicator to the base station. Therefore, a quantity of to-be-selected vectors is reduced by using a first-stage feedback and a second-stage feedback, thereby reducing calculation complexity of third-stage feedback, and reducing a quantity of bits in the third-stage feedback.

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.
