POWER CONTROL METHOD, DEVICE, AND SYSTEM OF PHYSICAL UPLINK CONTROL CHANNEL

摘要

Embodiments of the present invention provide a power control method, device, and system of a physical uplink control channel (PUCCH). The method comprises: receiving a DCIx on the current frame, wherein the DCIx carries a TPC command; determining whether the DCIx is a virtual detection DCIx; discarding the TPC command carried by the DCIx if the DCIx is a virtual detection DCIx; performing PUCCH power control based on the TPC command if the DCIx is not a virtual detection DCIx. The power control method, device, and system of the PUCCH provided by embodiments of the present invention improve the accuracy and validity of the PUCCH power control.
