In release 8 of the LTE standard (“Rel-8”), downlink data transmissions of one or more user equipments (UEs) in one subframe may be scheduled by control channels of different subframes. The resources for use in acknowledging whether or not a downlink data transmission was successfully received by a UE may be based on a starting control channel element (CCE) of a corresponding control channel. Two or more control channels of different subframes may have the same starting CCE, which may lead to acknowledgment resource collisions between the one or more UEs. Therefore, certain aspects of the present disclosure provide techniques to avoid acknowledgment resource collisions between the one or more UEs. |
