Information transmission method, base station, and user equipment

An apparatus, comprising:

• a processor;
• and a memory coupled to the processor and for storing instructions which, when executed by the processor, cause the apparatus to:
• receive a beam indication signal on at least one beam from a base station, wherein the beam indication signal carries identity information of the at least one beam,
• obtain the identity information of the at least one beam according to the beam indication signal,
• obtain a signal quality of the at least one beam,
• determine, according to the signal quality of the at least one beam, a primary beam and a secondary beam each for carrying a downlink signal,
• send a first beam report message to the base station, wherein the first beam report message carries identity information of the primary beam and the secondary beam,
• receive an instruction from the base station, wherein the instruction is used to instruct the UE to send a sounding reference signal (SRS) on a first SRS resource when the primary beam works normally and send the SRS on a second SRS resource when the primary beam works abnormally,
• determine whether a signal quality of the primary beam is less than a preset threshold for a preset time period, thereby determine whether the primary beam is abnormal,
• when it is determined the primary beam is abnormal, send the SRS to the base station on the second SRS resource, and
• when it is determined the primary beam is normal, send the SRS on the first SRS resource,
• wherein the first SRS resource is different than the second SRS resource.

A non-transitory, computer-readable storage medium comprising instructions which, when executed by a processor of a computer, cause the computer to:

• receive a beam indication signal on at least one beam from a base station, wherein the beam indication signal carries identity information of the at least one beam;
• obtain the identity information of the at least one beam according to the beam indication signal;
• obtain a signal quality of the at least one beam;
• determine, according to the signal quality of the at least one beam, a primary beam and a secondary beam each for carrying a downlink signal;
• send a first beam report message to the base station, wherein the first beam report message carries identity information of the primary beam and the secondary beam;
• receive an instruction from the base station, wherein the instruction is used to instruct the UE to send a sounding reference signal (SRS) on a first SRS resource when the primary beam works normally and send the SRS on a second SRS resource when the primary beam works abnormally;
• determine whether a signal quality of the primary beam is less than a preset threshold for a preset time period, thereby determine whether the primary beam is abnormal;
• when it is determined the primary beam is abnormal, send the SRS to the base station on the second SRS resource;
• and when it is determined the primary beam is normal, send the SRS on the first SRS resource,
• wherein the first SRS resource is different than the second SRS resource.
