Abstract: Example data transmission methods and data transmission apparatus are provided. One example method includes receiving a precoding matrix index (PMI) by a first access network device from a terminal device. The first access network device determines a weighted precoding matrix based on the PMI and a preset matrix. Downlink data of the terminal device is precoded by the first access network device based on the weighted precoding matrix to obtain the precoded downlink data. The weighted precoding matrix is a 4×2 matrix, and values of the last two elements in a first column and the first two elements in a second column of the weighted precoding matrix are all zeros. The precoded downlink data is sent by the first access network device to the terminal device.

Abstract: A feeding network, an antenna, an antenna system, a base station, and a beam forming method. The antenna includes an array antenna, a feeding network, and an antenna port. The array antenna includes a plurality of radiating elements. Each output of each feeding network is connected to at least one radiating element in the array antenna. Each input of each feeding network is connected to the antenna port. Each feeding network has one input and two outputs, and one of the two outputs includes a phase shifter. The phase shifter has a first operating state to increase the coverage space of beam forming.

Abstract: Embodiments of this application disclose a method for scheduling a terminal. The method includes the following operations: receiving a precoding matrix indication PMI value and reference signal received power RSRP that are sent by user equipment; determining, based on the PMI value, grouping of a network area corresponding to the user equipment; and determining, based on the RSRP, a network area in which the user equipment is located. This application has the advantage of avoiding interference between network areas.
