Abstract
A transmission method and apparatus, a device, and a readable storage medium are disclosed. The method includes: sending, by a terminal, information for determining a position of a valid orthogonal basis and a coefficient of the valid orthogonal basis to a network side.
Claims20
A transmission method, comprising:
- sending, by a terminal, information for determining a position of a valid orthogonal basis and a coefficient of the valid orthogonal basis to a network side;
- wherein the information for determining the position of the valid orthogonal basis comprises at most two of spatial domain orthogonal basis, bitmap, or delay position;
- wherein the method further comprises:
- receiving, by the terminal, first indication information, wherein the first indication information indicates the terminal to send the delay position and the bitmap, and the first indication information also indicates the terminal not to send the spatial domain orthogonal basis;
- the sending, by the terminal, the information for determining the position of the valid orthogonal basis to the network side comprises:
- sending, by the terminal, the delay position and the bitmap to the network side;
- or sending, by the terminal, only the delay position to the network side, without sending the bitmap to the network side.

A terminal, comprising:
- a processor, a memory, and a program stored on the memory and capable of running on the processor, wherein the program, when being executed by the processor, implements:
- sending information for determining a position of a valid orthogonal basis and a coefficient of the valid orthogonal basis to a network side, wherein the information for determining the position of the valid orthogonal basis comprises at most two of spatial domain orthogonal basis, bitmap, or delay position;
- wherein the program is executed by the processor to further implement:
- receiving first indication information, wherein the first indication information indicates the terminal to send the delay position and the bitmap, and the first indication information also indicates the terminal not to send the spatial domain orthogonal basis;
- the sending the information for determining the position of the valid orthogonal basis to the network side comprises:
- sending the delay position and the bitmap to the network side;
- or only sending the delay position to the network side, without sending the bitmap to the network side.
