 logic, at least a portion of which is in hardware, to detect in-device coexistence interference between multiple radios that when operational use different wireless protocols, one of which comprises a long term evolution (LTE) wireless protocol, and send information to indicate a time division multiplexing (TDM) pattern for a hybrid automatic repeat request (HARQ) process for the LTE wireless protocol, the TDM pattern to indicate one or more subframes for use by the HARQ process; and   a radio-frequency (RF) transmitter coupled to the logic, the RF transmitter to transmit electromagnetic signals representing the information on a wireless uplink channel.
