摘要： Embodiments of the present invention disclose a method for measuring downlink channel quality, a transmit end, a receive end, and a system. The method for measuring downlink channel quality includes: transmitting, by a transmit end, at least two mixed pilot signals to a receive end separately by using at least two physical antennas, where 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; sending, by the transmit end, a first codebook subset restriction instruction to the receive end, where the first codebook subset restriction instruction carries a rank indication RANK and at least one precoding matrix index PMI; and receiving, by the transmit end, 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, downlink channel quality of an equivalent channel of a specified antenna is accurately acquired, and therefore a suitable serving antenna is selected for a receive end, thereby improving signal quality.

摘要： A wireless communications apparatus and method are used to resolve a problem in the prior art that increasing a system capacity by using a HetNet method causes a waste of device resources and is difficult to implement in practical application. An antenna module transmits a wide beam, transmits at least two narrow beams to a coverage area of the wide beam, and performs data transmission with UE within the coverage area of the wide beam by using at least one transmitted beam. By means of the foregoing method, under a condition that no new site is added, a quantity of transmit antennas within a unit area can be increased, and a capacity within the unit area can be increased, which is not limited in practical application and is easy to implement.

摘要： 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.
