Abstract
According to aspects of the disclosure, a method and system are provided for managing signaling in a wireless communication network. In accordance with the disclosure, a base station serves a plurality of user equipment devices (UEs) via an air interface extending between the base station and the UEs. The base station also receives, on an uplink of the air interface, a report from each UE indicating channel state information (CSI). The base station periodically receives the report from each UE according to a CSI reporting rate specified by the base station for the UE. The base station may determine that a level of loading on the uplink is greater than a threshold load value. Responsive to such determination, the base station selects a subset of the plurality of UEs and reduces the CSI reporting rate for the selected subset of the plurality of UEs to reduce congestion on the uplink.
