## Abstract

Provided are an information sending and receiving method and device, a storage medium and a processor. The information sending method includes: generating first signaling in a case where K elements in a beam-related parameter set exceed a first threshold corresponding to the K elements, wherein the K is an integer greater than or equal to 1; and sending the first signaling to a second communication node, wherein the first signaling carries information related to a reference signal.

## Claims

### Claim 1

An information sending method, executed by a first communication node, and comprising:
receiving a reference signal sent by a second communication node;
determining information relaxed to the reference signal, wherein the information comprises at least one of the following: information of a reference signal related index, and information of a Reference Signal Received Power (RSRP); and
feeding the information back to the second communication node;
wherein in a case where the reference signal is one of X reference signals in a first reference signal group, an RSRP corresponding to one of the X reference signals is fed back in a form of differential RSRP, wherein the X is positive integers greater than or equal to 1, and reference power for calculating the differential RSRP of the X reference signals comprises: an RSRP of a specified reference signal out of the first reference signal group.

### Claim 2 (depends on 1)

The method as claimed in claim 1, wherein the reference power for calculating the differential RSRP of the X reference signals further comprises:
an RSRP of a specified reference signal in a second reference signal group.

### Claim 3 (depends on 2)

The method as claimed in claim 2, wherein the specified reference signal is a reference signal having a maximum RSRP in the second reference signal group.

### Claim 4 (depends on 1)

The method as claimed in claim 1, wherein a step value of the differential RSRP is determined according to a pre-defined step value.

### Claim 5

An information sending method, executed by a second communication node, and comprising:
sending a reference signal to a first communication node; and
receiving information fed back by the first communication node and related to the reference signal, wherein the information comprises at least one of the following: information of a reference signal related index, and information of a Reference Signal Received Power (RSRP);
wherein in a case where the reference signal is one of X reference signals in a first reference signal group, an RSRP corresponding to the X reference signals is received in a form of differential RSRP, the X is positive integers greater than or equal to 1, and reference power for calculating the differential RSRP of the X reference signals comprises: an RSRP of a specified reference signal out of the first reference signal group.

### Claim 6 (depends on 5)

The method as claimed in claim 5, wherein the reference power for calculating the differential RSRP of the X reference signals further comprises:
an RSRP of a specified reference signal in a second reference signal group.

### Claim 7 (depends on 6)

The method as claimed in claim 6, wherein the specified reference signal is a reference signal having a maximum RSRP in the second reference signal group.

### Claim 8 (depends on 5)

The method as claimed in claim 5, wherein a step value of the differential RSRP is determined according to a pre-defined step value.

### Claim 9 (depends on 1)

An information receiving device, comprising:
a memory, configured to store a program
a processor, configured to run the program to perform the steps of the information receiving method as claimed in claim 1.

### Claim 10 (depends on 5)

An information sending device comprising:
a memory, configured to store a program; and
a processor, configured to run the program to perform steps of the information sending method as claimed in claim 5.
