Uplink transmission indication method and device, and communication equipment

[0102]Example one

[0103]In this embodiment, the uplink data channel is codebook-based uplink transmission, and the indication information indicates SRS resource index information.

[0104]In order to improve the reliability of PUSCH transmission, the terminal can use up to 2 beams for single-layer transmission. The number of bits occupied by the indication information is:Where NSRS Is the number of SRS resources, NTx It is the number of transmit beams simultaneously used by the terminal during uplink transmission. When NSRS When equal to 2, 3, 4, the mapping relationship between the indication information and the indicated SRS resource is as follows:

[0105]

[0106]In NSRS It is equal to 2 and includes SRS resources 0 and 1, when the indication information is 0, it indicates SRS resource 0; when the indication information is 1, it indicates SRS resource 1; when the indication information is 2, it indicates SRS resources 0 and 1.

[0107]In NSRS Equal to 3, including SRS resources 0, 1, and 2, whe

[0109]Example two

[0110]In this embodiment, the uplink data channel uses codebook-based uplink transmission, and the number of bits occupied by the indication information is min{NSRS ,NTx }, when NSRS =NTx =2, the mapping relationship between the indication information and the indicated SRS resource is as follows:

[0111] Bit field mapped to index SRI(s), NSRS=2 00 11 20,1 3Reserved

[0112]In NSRS It is equal to 2 and includes SRS resources 0 and 1, when the indication information is 0, it indicates SRS resource 0; when the indication information is 1, it indicates SRS resource 1; when the indication information is 2, it indicates SRS resources 0 and 1.

[0113]Example three

[0114]In this embodiment, the network side device sends DCI to the terminal. The indication information in the DCI indicates the TCI state index. After receiving the indication information, the terminal sends the PUSCH according to the spatial information used for receiving downlink transmission, which can reduce the time of the beam indication. Extension.

[0115]The embodiment of the present invention also provides an uplink transmission indication device, which is applied to network side equipment, such asimage 3 As shown, it includes a processor 31 and a transceiver 32,

[0116]The transceiver 32 is configured to send instruction information to the terminal, where the instruction information indicates any of the following:

[0117]The index of at least one sounding reference signal resource;

[0118]Transmission configuration indication status index.

[0119]In this embodiment, the network side device sends indication information to the terminal, and the indication information
