Alleviating mobile device overload conditions in a mobile communication system
First Claim
1. A method of operating a user equipment in a mobile communications system, the method comprising:
- operating a receiver of the user equipment to receive one or more data blocks via a channel;
detecting a user equipment overload condition;
in response to the detected user equipment overload condition, reporting a channel quality indicator (CQI) value to a serving base station, wherein the reported CQI value represents a channel quality that is lower than an actual quality of the channel;
operating the user equipment in a manner that is consistent with the reported CQI value, including sending negative acknowledgements (NAKs) to the serving base station at a rate that is consistent with operation by means of a channel having a quality that corresponds to the reported CQI value,wherein sending NAKs to the serving base station at the rate that is consistent with operation by means of the channel having the quality that corresponds to the reported CQI value is further performed in a manner such that the NAKs are distributed over time in a way that emulates a distribution of NAKs that corresponds to the channel having the quality that corresponds to the reported CQI value.

Abstract
A user equipment (UE) in a mobile communications system is operated in a manner that alleviates or avoids an overload condition in the UE. This involves operating a receiver of the UE to receive one or more data blocks via a channel. In response to a user equipment overload condition being detected, a channel quality indicator (CQI) value is reported to a serving base station, wherein the reported CQI value represents a channel quality that is lower than an actual quality of the channel. The UE is then operated in a manner that is consistent with the reported CQI value. UE overload conditions include overheating, and an inability to process received data blocks at the rate at which they are being received.

12. An apparatus for operating a user equipment in a mobile communications system, the apparatus comprising:
-
logic configured to operate a receiver of the user equipment to receive one or more data blocks via a channel; logic configured to detect a user equipment overload condition; logic configured to report a channel quality indicator (CQI) value to a serving base station in response to the detected user equipment overload condition, wherein the reported CQI value represents a channel quality that is lower than an actual quality of the channel; logic configured to operate the user equipment in a manner that is consistent with the reported CQI value, including sending negative acknowledgements (NAKs) to the serving base station at a rate that is consistent with operation by means of a channel having a quality that corresponds to the reported CQI value, wherein the logic configured to send NAKs to the serving base station at the rate that is consistent with operation by means of the channel having the quality that corresponds to the reported CQI value operates in a manner such that the NAKs are distributed over time in a way that emulates a distribution of NAKs that corresponds to the channel having the quality that corresponds to the reported CQI value. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
