Embodiments of this application disclose a wireless communication method, a related apparatus, and a device. Configuring at least two virtual antenna mapping matrices, where each of the at least two virtual antenna mapping matrices indicates a mapping relationship between four antenna ports and N physical channels, and N is an integer greater than 4; obtaining channel state information of a target terminal device in a target cell; and then determining, based on the channel state information, that the mapping relationship between the four antenna ports and the N physical channels is a mapping relationship indicated by a target virtual antenna mapping matrix in the at least two virtual antenna mapping matrices, and performing wireless communication with the target terminal device by using the target virtual antenna mapping matrix.

Wireless communication method, related apparatus, and device

A joint transmission (JT) method and apparatus, the method including selecting, by a network device of a serving cell, a JT user equipment and a coordinated neighboring cell of the JT user equipment, sending, by the network device of the serving cell, a JT user equipment request to a network device of the coordinated neighboring cell, scheduling the JT user equipment and sending scheduling information to the network device of the coordinated neighboring cell, and sending, by the network device of the serving cell, a reference signal and data to the JT user equipment according to the scheduling information, where the reference signal sent by the network device to the JT user equipment by the network device of the serving cell is the same as a reference signal sent by the network device of the coordinated neighboring cell of the JT user equipment to the JT user equipment.

Data transmission method, apparatus, and system

A method includes: an RRU selection decision cycle of a current RRU shared cell arriving; and determining, according to a current downlink measurement item of a user terminal and an uplink measurement item of each RRU, that at least one RRU among the RRUs transmits a downlink carrier signal; or, determining, according to the current downlink measurement item of the user terminal, the uplink measurement item of each RRU, and power specification of each RRU, that at least one RRU among the RRUs transmits a downlink carrier signal, where a downlink channel includes: a traffic channel and a stand-alone dedicated control channel.
