Abstract: A communication method includes receiving N pilot signals from a network device by using N channel state information (CSI) resources. The N CSI resources are in a one-to-one correspondence with the N pilot signals, N is an integer greater than or equal to 2, and the N pilot signals correspond to N mapping relationships between antenna ports of the network device and transceiver antennas of the network device, wherein at least two of the N mapping relationships between the antenna ports of the network device and the transceiver antennas of the network device are different, or the N pilot signals correspond to N inter-polarization phases, wherein at least two of the N inter-polarization phases are different. The method also includes performing channel measurement on the N CSI resources based on the corresponding pilot signals. The method further includes sending channel state information to the network device.

Abstract: Embodiments are disclosed of a hybrid automatic repeat request feedback method and apparatus, and relates to the field of communications technologies. The hybrid automatic repeat request feedback method is applied to a receive end. After receiving data information sent by a transmit end, the receive end may determine, when target data in the data information is not checked, a measurement value of the target data, then generate feedback information based on the measurement value, and subsequently, send the feedback information to the transmit end, so that the transmit end can determine, based on the feedback information, whether the target data needs to be retransmitted.

Abstract: This application provides a method for adjusting a half-power angle of an antenna, to adjust a maximum half-power angle or a maximum beam gain of an individual transceiver channel. The method includes: first determining that M antenna elements in N antenna elements connected to a first transceiver channel of an access network device need to be turned on or off, where N>M≥1, and both N and M are integers, that is, a quantity of antenna elements driven by the first transceiver channel needs to be adjusted; and then sending first indication information to the access network device, where the first indication information is used to indicate to turn on or off the M antenna elements.
