Abstract: This application provides a communication method and apparatus. The communication method includes: receiving measurement configuration information from a network device, where the measurement configuration information is used to configure a channel measurement resource and M interference measurement resources, and M is a positive integer greater than or equal to 1; and sending a bitmap to the network device, where the bitmap includes one or more bits, each bit corresponds to one or more interference measurement resources and has a value indicating interference of the one or more interference measurement resources to the channel measurement resource, and the M interference measurement resources include the one or more interference measurement resources.

Abstract: The present disclosure disclose a method including: a transmit end transmits at least two mixed pilot signals to a receive end separately by using at least two physical antennas. The at least two mixed pilot signals are separately obtained after preset pilot signals corresponding to logical antennas in the at least two logical antennas are weighted by using a precoding weight matrix. The transmit sends a first codebook subset restriction instruction to the receive end. The first codebook subset restriction instruction carries a rank indication RANK and at least one precoding matrix index PMI. The transmit end receives a channel quality feedback message that is fed back by the receive end according to downlink channel quality of an equivalent channel of a specified antenna. According to the present invention, a suitable serving antenna is selected for a receive end, thereby improving signal quality.

Abstract: According to a communication method and a base station that are provided in embodiments of the present invention, the base station transmits a broad beam that covers a sector of the base station and narrow beams whose coverage areas completely fall within a coverage area of the broad beam, which implements that under a premise that a coverage area of the sector of the base station maintains unchanged by using the broad beam, enhanced coverage of the sector is further achieved by using the narrow beams, thereby improving spectral efficiency. In the solutions, a sector coverage area of the broad beam transmitted by the base station still maintains unchanged, and therefore, a coverage relationship between sectors is not affected. In addition, neither an additional site backhaul resource nor additional standardization support is required in the solutions.
