1. A method for wireless communications, comprising:
- determining at least one potential gap pattern configuration for a first radio access technology (RAT), the at least one potential gap pattern configuration satisfying a scheduling timeline constraint of the first RAT and a timeline constraint of a second RAT, each potential gap pattern comprising a subframe for a potential uplink grant and a subframe for hybrid automatic repeat request (HARQ) feedback to satisfy the scheduling timeline constraint of the first RAT;
selecting one of the at least one potential gap pattern configuration that reduces conflicts between the first RAT and the second RAT; and
transmitting an indication of the selected gap pattern configuration to a base station, the indication intended for the base station to approve the selected gap pattern configuration and customize at least one HARQ process to correspond with the selected gap pattern configuration, the customizing comprises changing at least one of;
uplink HARQ grant to transmission, transmission to acknowledgment (ACK), downlink HARQ grant to ACK, or a combination thereof.

Abstract
To improve performance in devices capable of communication using multiple radio access technologies (RATs), a gap pattern may be constructed in which a first RAT is quieted during certain times to allow for a second RAT to operate without interference. Gap patterns may be constructed based on timeline constraints, such as grant scheduling and HARQ performance, or based on desired performance levels of one or more of the RATs. Gap patterns may be selected by a user equipment or base station. Gap patterns may be selected to protect information in certain subframes. Potential gap patterns may be assigned weights indicating their desirability.
