Beam information reporting and receiving method and apparatus
A beam information reporting and receiving method and apparatus are disclosed. The method at least includes: A terminal device receives first activation signaling from a network device, where the first activation signaling is used to activate a first cell, and the first cell is a secondary cell that has a capability of sending a physical uplink control channel PUCCH.
