Management of channel state information reporting rate in a communications system
First Claim
1. A method for managing signaling in a wireless communication system, the method comprising:
- serving, by a base station, a plurality of user equipment devices (UEs) via an air interface extending between the base station and the plurality of UEs;
receiving, on an uplink of the air interface, a report from each UE indicating channel state information (CSI), wherein the report indicating CSI is periodically received from each UE according to a CSI reporting rate specified by the base station for the UE;
while serving the plurality of UEs, determining that a level of loading on the uplink is greater than a threshold load value; and
responsive to the determining that the level of loading on the uplink is greater than the threshold load value;
(i) selecting a subset of the plurality of UEs, and (ii) responsive to selecting the subset, reducing the CSI reporting rate for the selected subset of the plurality of UEs to reduce congestion on the uplink.

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.

10. A method for managing signaling in a wireless communication system, the method comprising:
-
serving, by a base station, a plurality of user equipment devices (UEs) with carrier aggregation on a plurality of component carriers through an air interface between the base station and the plurality of UEs; for each component carrier of each UE, periodically receiving a report indicating channel state information (CSI) for the component carrier of the UE, wherein the report is received for each component carrier of each UE according to a CSI reporting rate specified by the base station for the component carrier of the UE, wherein the reports are received on an uplink of the air interface; while serving the plurality of UEs, determining that a level of loading on the uplink is greater than a threshold load value; and responsive to determining that the level of loading on the uplink is greater than the threshold load value;
(i) selecting from the plurality of component carriers of the plurality of UEs a subset including one or more component carriers of one or more UEs, and (ii) responsive to selecting the subset, reducing the CSI reporting rate for the selected subset. - View Dependent Claims (11, 12, 13, 14)
