Abstract
Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of separate training approach for CSI feedback. The method comprises receiving, at a terminal device and from a network device, a training dataset associated with CSI, a codebook of the network device and a first set of codeword indices associated with the codebook; and determining a CSI feedback compression of the terminal device based on a first codeword and a second codeword generated based on the training dataset, the codebook of the network device and the first set of codeword indices.
Claims13
An apparatus comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
- receive, from a network device, a training dataset associated with channel state information, CSI, a codebook of the network device and a first set of codeword indices associated with the codebook;
- and
- determine a CSI feedback compression of the apparatus based on a first codeword and a second codeword generated based on the training dataset, the codebook of the network device and the first set of codeword indices.
An apparatus comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:

- determine a first set of codeword indices based on the latent vector and a codebook of the apparatus;
- and
- transmit, to a terminal device, the training dataset, the first set of codeword indices and the codebook.
