In other words, the weight mapping information may include a correspondence or mapping relationship between the antenna pattern and the weight information of a group of antenna ports.

The weight information of the plurality of antenna ports is used to indicate which of the plurality of antenna ports is weighted and mapped to which antenna physical channel.

It should be understood that the antenna mode determined by the base station may be an antenna mode acquired by the base station, for example, an antenna mode configured for the base station on the network side, or an antenna mode configured by the base station, for example, an antenna mode selected by the base station according to a preset policy. It may also be an antenna mode preset by the base station.

It should also be understood that the information of the antenna mode may include information of the antenna transmission mode and information of the number of antenna ports. Alternatively, the information of the antenna mode may also be an identification or index of the antenna mode indicating a combination of a predetermined antenna transmission mode and a predetermined number of antenna ports.

In addition, the obtaining module 230 may obtain the information of the antenna mode directly from the base station, or may indirectly obtain the information of the antenna mode from the base station. The embodiment of the present invention is not limited thereto. For example, the obtaining module 230 may also acquire the network from the network side. The side is the information of the antenna mode configured by the antenna.

For example, the weight mapping information of the antenna may be stored in a storage unit of the antenna, and the obtaining module 230 may acquire the weight mapping information from the antenna and update the weight mapping information in the base station maintenance center device. For example, when the antenna hardware is replaced, or the hardware configuration of the antenna changes, the weight mapping information stored in the antenna is updated, and the base station maintenance center device is triggered to obtain the updated weight mapping information from the antenna, and The mode of the antenna and the updated weight mapping information determine the weight information of the antenna port such that the weight information used to process the data stream signal of the antenna port matches the actual weight mapping information of the antenna. The acquisition module 230 can also periodically monitor the rights of the antenna. Value mapping information changes. For example, the obtaining module 230 may send a scan message to multiple antennas, or the obtaining module 230 may construct a scan frame to send to multiple antennas. For example, the AIMSG protocol may be used to send scan messages or scan frames to multiple antennas for storage in the antenna. When the value mapping information changes, the weight mapping information matching the antenna actually used is downloaded from the antenna.

The weight mapping information matching the actual antenna can be obtained, and the problem that the weight mapping information file is not updated due to the antenna replacement is solved. It also solves the problem that the actual weight mapping information cannot meet the needs.

For example, the weight mapping table includes a frequency band entry, the information in the frequency band entry is a frequency band corresponding to a specific mode, the specific antenna mode may correspond to multiple frequency bands, and the determining module 210 may select an optimal frequency band according to requirements. Since the signal is transmitted using a predetermined frequency band, the antenna is transmitted in an optimal waveform or transmitted on a predetermined frequency resource, which reduces errors and improves the efficiency of transmitting signals. According to an embodiment of the present invention, the weight information of the antenna port is a weight matrix, the number of columns of the weight matrix is equal to the number of the plurality of antenna ports, and the number of rows of the weight matrix is equal to the number of the plurality of physical channels, and the weight Each element in the value matrix is used to indicate a weight of each of the plurality of antenna ports on a corresponding physical channel of the antenna, wherein the adjustment module is specifically configured to use the weight matrix and the signal matrix of the plurality of data stream signals Multiplying to generate a weighted data stream signal corresponding to a plurality of physical channels of the antenna, the number of rows of the signal matrix being equal to the number of the plurality of antenna ports.

It should be understood that the weight information of the plurality of antenna ports may also be other forms than the matrix, such as a form indicating weight information of the plurality of antenna ports on the plurality of physical channels. In addition, multiple antenna ports are mapped to multiple physical channels, and some of the plurality of antenna ports may be mapped to some of the plurality of physical channels, or each antenna port may be mapped to each physical channel. Since the weight matrix is used to process multiple data signals, the processing is streamlined.
