Abstract

Embodiments of this application relate to the field of communications technologies and disclose a communication method and a device. The method includes: determining an offset based on a first quantity, wherein the first quantity is a quantity of beams that are used to determine signal quality of a first cell; and determining the signal quality of the first cell based on the offset.

Claims (44)

1. A communication method, comprising:

obtaining a first threshold to be used to derive a first signal quality of a cell, wherein the first threshold is configured by a network device;

receiving indication information from the network device, wherein the indication information comprises first indication information indicating which beam measurement information needs to be reported;

measuring a signal quality of each beam of at least one beam in the cell;

deriving the first signal quality of the cell; and

sending measurement information based on the indication information and information of the first signal quality of the cell to the network device;

wherein deriving the first signal quality comprises:

in a case that the at least one beam comprises one or more beams whose respective signal quality is above the first threshold, deriving the first signal quality of the cell based on an average value of the respective signal qualities of the one or more beams; and

in a case that the respective signal quality of each beam of the at least one beam is below the first threshold, deriving the first signal quality of the cell based on a respective signal quality of a beam that has a highest signal quality in the at least one beam.

2. The method according to claim 1 , wherein the beam that has the highest signal quality is a beam with a respective signal quality having a smallest difference from the first threshold in the at least one beam.

3. The method according to claim 1 , wherein the cell comprises a serving cell or at least one neighboring cell of the serving cell.

4. The method according to claim 1 , further comprising:

performing adjustment on the first signal quality of the cell according to an offset to obtain a second signal quality of the cell, the offset being based on a quantity of beams that are used to determine the first signal quality of the cell.

5. The method according to claim 1 , wherein the first signal quality of the cell enables the network device to use to perform mobility control.

6. The method according to claim 1 , wherein the beam measurement information that needs to be reported comprises a beam identifier and a beam measurement result associated with the beam identifier.

7. The method according to claim 1 , wherein the beam measurement information that needs to be reported comprises a beam identifier.

8. An apparatus, comprising at least one circuitry configured to:

obtain a first threshold to be used to derive a first signal quality of a cell, wherein the first threshold is configured by a network device;

13. The apparatus according to claim 8 , wherein the beam measurement information that needs to be reported comprises a beam identifier and a beam measurement result associated with the beam identifier.

14. The apparatus according to claim 8 , wherein the beam measurement information that needs to be reported comprises a beam identifier.

15. A communications method, comprising:

configuring a first threshold for a terminal to be used to derive a first signal quality of a cell, and sending the first threshold to the terminal;

sending indication information to the terminal, wherein the indication information comprises first indication information indicating which beam measurement information needs to be reported; and

receiving measurement information and information of the first signal quality of the cell from the terminal, the measurement information being based on the indication information, the signal quality of the cell being based on the first threshold, and wherein,

in a case that there are one or more beams, in the cell, whose respective signal quality is above the first threshold, the signal quality of the cell is based on an average value of the respective signal qualities of the one or more beams, and

in a case that the respective signal quality of each beam of the one or more beams in the cell is below the first threshold, the signal quality of the cell is based on a respective signal quality of a beam that has a highest signal quality in the one or more beams of the cell.

16. The method according to claim 15 , wherein the beam that has the highest signal quality is a beam with a respective signal quality having a smallest difference from the first threshold in the beam(s) of the cell.

17. The method according to claim 15 , wherein the cell comprises a serving cell or at least one neighboring cell of the serving cell.

18. The method according to claim 15 , further comprising:

performing mobility control based on the signal quality of the cell.

19. The method according to claim 15 , wherein the beam measurement information that needs to be reported comprises a beam identifier and a beam measurement result associated with the beam identifier.

20. The method according to claim 15 , wherein the beam measurement information that needs to be reported comprises a beam identifier.
