step 210, when configuring the uplink to transmit the PUSCH based on the DFT-S-OFDM waveform, sending a Downlink Control Information (DCI) signaling.

The DCI signaling is used for indicating a plurality of frequency band resources to be scheduled and TPMI corresponding to each frequency band resource to be scheduled to the terminal equipment; the antenna ports corresponding to different frequency band resources to be scheduled are different, and the antenna ports corresponding to the different frequency band resources to be scheduled are determined by the uplink transmission codebook indicated by the TPMI; the frequency band resource to be scheduled is a continuous section of PRB used for transmitting PUSCH.

Before sending the DCI signaling, the method further comprises the following steps:

determining an optional codebook set corresponding to the terminal equipment according to the number of antenna ports of the terminal equipment and the antenna coherence characteristic capability;

and determining a plurality of frequency band resources to be scheduled and TPMI corresponding to each frequency band resource to be scheduled according to the selectable codebook set.

The terminal device reports the antenna port number and the antenna coherence characteristic capability of the terminal device to the network side device, so that the network side device determines an optional codebook set corresponding to the terminal device according to the antenna port number and the antenna coherence characteristic capability of the terminal device.

Currently, the antenna coherence characteristic capability of the terminal device includes the following three types:

A. full-coherence (full-coherence), which means that the amplitude-phase coherence relationship between the transmitting antennas supported by the terminal device is almost constant in time;

B. incoherent (non-coherence), which means that the amplitude-phase coherence relationship between the transmitting antennas supported by the terminal device varies randomly in time;

C. partial-coherence (partial-coherence) means that the amplitude-phase coherence relationship between the transmitting antennas supported by the terminal device is divided into 2 groups, the antennas within a group are all coherent, and the antennas between groups are incoherent.

Corresponding to the number of antenna ports and the antenna coherence characteristic capability of the terminal equipment, the uplink transmission codebook indicated by the TPMI comprises the following steps:

A. table 1 is an uplink transmission codebook for 2 antenna ports:
