SYSTEMS AND METHODS FOR COEXISTENCE IN WLAN AND LTE COMMUNICATIONS
First Claim
1. A wireless communications device, comprising:
- a first transceiver configured to operate using a first wireless protocol;
a second transceiver configured to operate using a second wireless protocol; and
a coexistence manager configured to;
receive an allocation of network resources using the first transceiver;
predict intermodulation distortion (IMD) regarding an upcoming transmission using the first transceiver based, at least in part, on at least one characteristic determined from the allocation of network resources; and
selectively reduce transmit power at the second transceiver based, at least in part, on the predicted IMD when reception quality at the first receiver is below a desired threshold.

Abstract
This disclosure provides coexistence strategies for a combined wireless communications device using multiple wireless protocols, such as WLAN and LTE. Transmission power of a system using one wireless protocol is dynamically adjusted based on a determination of operating characteristics of a system using another wireless protocol. At least one of the operating characteristics may be determined from an allocation of network resources, examples of which include the transmission frequency for an upcoming transmission and the transmission power for an upcoming transmission. Further, the transmission power may be adjusted when the reception quality of the system using the other wireless protocol is below a desired threshold.
