Transmission method using dynamically adjusted beam set, base station, and terminal

A receiving method, comprising:

• receiving, by a terminal, first indication information from a base station using first layer signaling, wherein the first indication information indicates a first beam set;
• receiving, by the terminal, second indication information from the base station using second layer signaling, wherein the second indication information indicates at least one beam in the first beam set;
• and
• receiving, by the terminal, a signal from the base station using the at least one beam.

A terminal, comprising:

• at least one processor, and a transceiver, wherein
• the at least one processor is configured to:
• control the transceiver to receive first indication information from a base station using first layer signaling, wherein the first indication information indicates a first beam set;
• control the transceiver to receive second indication information from the base station using second layer signaling, wherein the second indication information indicates at least one beam in the first beam set;
• and
• control the transceiver to receive a signal from the base station using the at least one beam.
