Information transmission method and device

An information transmission method, comprising:

• obtaining, by a user equipment (UE), a first resource configured by a base station for the UE, the first resource being configured to be used by the UE to transmit a first signal comprising a sounding reference signal (SRS);
• and
• receiving, by the UE, first indication information transmitted by the base station;
• the first indication information indicating a correspondence between the first resource and a second resource, the second resource being configured to be used by the UE to transmit a second signal to the base station before the transmission of the first signal, the correspondence being used by the UE to determine a first beam for transmitting the first signal, and the first beam for transmitting the first signal being the same as a second beam for transmitting the second signal.

A base station, comprising:

• a processor;
• a memory coupled to the processor, the memory comprising instructions that, when executed by the processor, cause the base station to:
• configure a first resource for a user equipment (UE), the first resource being configured to be used by the UE to transmit a first signal comprising a sounding reference signal (SRS);
• and
• transmit first indication information to the UE;
• the first indication information indicating a correspondence between the first resource and a second resource, the second resource being configured to be used by the UE to transmit a second signal to the base station before the transmission of the first signal, the correspondence being used by the UE to determine a first beam for transmitting the first signal, and the first beam for transmitting the first signal being the same as a second beam for transmitting the second signal.
