Abstract
A method and device for handling hybrid automatic repeat request (‘HARQ’) operations during transmission mode changes, the method detecting a transmission mode change; and manipulating an HARQ process buffer based on the detecting. Further, a method and network element for handling hybrid automatic repeat request (‘HARQ’) operations during transmission mode changes, the method checking when a user equipment is in a transmission mode uncertainty window; and blocking communications to the user equipment or utilizing a downlink control information format 1A for communications to the user equipment.

A method for handling hybrid automatic repeat request (‘HARQ’) operations during transmission mode changes comprising:
- detecting a transmission mode change;
- and
- manipulating an HARQ process buffer based on the detecting.
A user equipment configured for handling hybrid automatic repeat request (‘HARQ’) operations during transmission mode changes comprising:
- a processor;
- and
- a communications subsystem;
- the processor and communications subsystem being configured to:
- detect a transmission mode change;
- and
- manipulate an HARQ process buffer based on the detecting.
A method for handling hybrid automatic repeat request (‘HARQ’) operations during transmission mode changes comprising:
- checking when a user equipment is in a transmission mode uncertainty window;
- and
- blocking communications to the user equipment or utilizing a downlink control information format 1A for communications to the user equipment.
A network element configured for handling hybrid automatic repeat request operations comprising:
- a processor;
- and
- a communications subsystem,
- wherein the network element is configured to:
- check when a user equipment is in a transmission mode uncertainty window;
- and
- block communications to the user equipment or utilize a downlink control information format 1A for communications to the user equipment.
