Parameter resetting method and device, and parameter information receiving method and device

Abstract

Provided are a parameter resetting method and device, and a parameter information receiving method and device. The parameter resetting method includes that: after a PL corresponding to updated PL-RS parameter information takes effect, or after a beam state corresponding to updated beam state information takes effect, relevant parameters of closed-loop power control are reset. The described technical solution solves problems in the related art, such as a problem that in a process where a new beam takes effect and the PL of an old beam is still used, the closed-loop power control is likely to accumulate a large negative value, causing the transmission power to drop suddenly after the PL of the new beam takes effect.
