Channel state information CSI report mapping method, terminal, and network-side device

A terminal, comprising a processor, a memory, and a program or instructions stored in the memory and capable of running on the processor, wherein when the program or instructions are executed by the processor, implementing:

• feeding back X CSI reports to a network-side device according to a preset mapping rule, wherein
• the CSI report comprises information about target beams;
• the target beams comprise N pairs of first beams that can be simultaneously received by the terminal, wherein N is a positive integer greater than 1;
• and
• the preset mapping rule is a mapping rule that matches group-based beam reporting;
• wherein the preset mapping rule comprises a first rule;
• wherein
• the first rule comprises:
• a first CSI measurement resource indicator is arranged in a first position, and CSI measurement resource indicators of remaining beams are sequentially arranged in a form of beam pairs, wherein the first CSI measurement resource indicator is a CSI measurement resource indicator corresponding to a beam whose layer 1 measurement value is largest among the N pairs of first beams;
• and
• if the first rule is satisfied, the layer 1 measurement value corresponding to the first CSI measurement resource indicator is mapped, and layer 1 measurement values of the remaining beams are mapped based on differences between the layer 1 measurement value corresponding to the first CSI measurement resource indicator and the layer 1 measurement values of the remaining beams.

A non-transitory readable storage medium, wherein the non-transitory readable storage medium stores a program or instructions, and when the program or instructions are executed by a processor, following steps are implemented:

• feeding back, by a terminal, X CSI reports to a network-side device according to a preset mapping rule, wherein
• the CSI report comprises information about target beams;
• the target beams comprise N pairs of first beams that can be simultaneously received by the terminal, wherein N is a positive integer greater than 1;
• and
• the preset mapping rule is a mapping rule that matches group-based beam reporting;
• wherein the preset mapping rule comprises a first rule;
• wherein
• the first rule comprises:
• a first CSI measurement resource indicator is arranged in a first position, and CSI measurement resource indicators of remaining beams are sequentially arranged in a form of beam pairs, wherein the first CSI measurement resource indicator is a CSI measurement resource indicator corresponding to a beam whose layer 1 measurement value is largest among the N pairs of first beams;
• and
• if the first rule is satisfied, the layer 1 measurement value corresponding to the first CSI measurement resource indicator is mapped, and layer 1 measurement values of the remaining beams are mapped based on differences between the layer 1 measurement value corresponding to the first CSI measurement resource indicator and the layer 1 measurement values of the remaining beams.
