1. A method for reducing coexistence interference in a multi-radio wireless device, comprising:
- determining coexistence interference is occurring in the multi-radio device, wherein the multi-radio device includes a wireless wide area network (WWAN) transceiver that operates using discontinuous reception (DRX); and
configuring the multi-radio device to not monitor physical downlink control channel (PDCCHs) of the WWAN transceiver in the multi-radio device during an unscheduled period of discontinuous reception (DRX) for pending uplink retransmissions.

Abstract
Technology for reducing coexistence interference in a multi-radio wireless device is disclosed. In one method, a determination is made if coexistence interference is occurring in the multi-radio device. The multi-radio device is then configured to not monitor physical downlink control channels for pending uplink transmissions in a wireless wide area network (WWAN) transceiver in the multi-radio device that occur during an unscheduled period of discontinuous reception (DRX).
