1. A method of wireless communication, comprising:
using a first radio access technology and a second radio access technology, the second radio access technology utilizes a second frequency band adjacent to a first frequency band for the first radio access technology;
receiving one or more time division duplexing (TDD) configuration parameters for the first radio access technology;
determining that the UE is not scheduled on the first radio access technology during at least one downlink subframe based on at least the one or more TDD configuration parameters;
placing a transmitter of the UE in a filter bypass mode in which a transmit signal bypasses a transmit filter for the first radio access technology in response to the determining; and
scanning, by a receiver for the second radio access technology, while in the filter bypass mode, the second frequency band for a signal for the second radio access technology during the at least one downlink subframe not scheduled on the first radio access technology.
