Methods and apparatus for feeding back and receiving channel state information, and device and storage medium

A method for wireless communication, comprising:

• receiving, by a base station, a set of Channel State Information (CSI) parameters from a user device at a time-frequency resource position, wherein the set of CSI parameters comprises a first-level reference signal received power (RSRP) value at a physical layer that is jointly coded with at least another first-level RSRP value at the physical layer.

A device for wireless communication, comprising a processor that is configured to:

• jointly code a set of Channel State Information (CSI) parameters, wherein the set of CSI parameters comprises a first-level reference signal received power (RSRP) value at a physical layer that is jointly coded with at least another first-level RSRP value at the physical layer;
• and
• transmit the set of CSI parameters to a base station at a time-frequency resource position.
