Adaptive antenna selection for interference mitigation
First Claim
1. An apparatus, comprising:
- a processing element configured to;
determine that simultaneous communication of a first wireless communication technology and a second wireless communication technology causes performance degradation to a third wireless communication technology, wherein said performance degradation is a result of intermodulation products associated with the first and second wireless communication technologies; and
select two or more antennas used for the simultaneous communication of the first wireless communication technology and the second wireless communication technology based at least in part on determining that the simultaneous communication of the first wireless communication technology and the second wireless communication technology causes performance degradation to the third wireless communication technology, wherein the two or more antennas are selected to reduce the intermodulation products.

Abstract
This disclosure relates to performing antenna selection to reduce interference in a wireless device. According to some embodiments, it may be determined whether simultaneous communication according to first and second wireless communication technologies causes performance degradation to a third wireless communication technology. If the simultaneous communication according to first and second wireless communication technologies does cause performance degradation to the third wireless communication technology, selection of antenna(s) used for the communications may be based at least in part on the determination that the simultaneous communication according to the first and second wireless communication technologies causes performance degradation to the third wireless communication technology.

14. A method for operating a user equipment (UE) device, the method comprising:
-
determining a first transmission frequency for transmitting according to a first wireless communication technology; determining a second transmission frequency for transmitting according to a second wireless communication technology; determining one or more frequencies on which intermodulation products are generated from simultaneously transmitting on the first transmission frequency and the second transmission frequency; determining whether any of the one or more frequencies on which intermodulation products are generated at least partially overlap a frequency band associated with a third wireless communication technology; determining an activity status of the third wireless communication technology; performing antenna selection for transmitting signals according to at least one of the first wireless communication technology or the second wireless communication technology to reduce interference to the third wireless communication technology if the third wireless communication technology is active and the one or more frequencies on which intermodulation products are generated at least partially overlap a frequency band associated with the third wireless communication technology, wherein the antenna selection is performed to reduce the intermodulation products. - View Dependent Claims (15, 16, 17, 18, 19, 20)
