UPLINK POWER CONTROL METHOD, NETWORK NODE AND SYSTEM

摘要

Embodiments of the present invention disclose a method for uplink power control, a network node and a system, which relates to the field of communication technologies, and the method includes: a first network node transmits a first indication message to a second network node, wherein the first indication message includes a time pattern and/or a maximum transmission power for an uplink transmission performed by a user equipment (UE) on the second network node, and the time pattern is used for controlling a transmission time of the uplink transmission performed by the UE. The present invention is applicable to uplink power control for the user equipment UE in a carrier aggregation scenario.
