Multi-radio coexistence
First Claim
1. A method of wireless communication, comprising:
- measuring a channel quality of a first downlink channel received from a serving cell of a first radio access technology;
generating a channel measurement report based on the measured channel quality;
altering, based at least in part on interference from a radio of a second radio access technology, the channel measurement report to compensate for a predicted backoff applied by the serving cell to received channel measurement values;
reporting the altered channel measurement report to the serving cell; and
receiving a second downlink channel from the serving cell, the second downlink channel having a throughput rate based at least in part on the altered channel measurement report.

Abstract
A method of wireless communication includes adjusting a channel quality indicator (CQI) to compensate for coexistence interference experienced between communication resources (such as an LTE radio and a Bluetooth radio). The CQI may be set to zero, falsely indicating to a serving enhanced NodeB that a UE is out of range, thereby creating a gap in LTE operation that may be used by an alternate radio access technology. To compensate for fluctuating interference, the CQI may be adjusted to incorporate average coexistence interference over a period of time. Alternatively, the CQI at a time may incorporate coexistence interference regardless of whether interference is experienced at that specific time. A CQI value may also be boosted to compensate for a CQI backoff. CQI may be adjusted to avoid a spiral of death effect.
