1. A method for wireless communications comprising:

  • communicatively connecting with a user equipment (UE), a first cell, and a second cell;

    determining a sub-frame pairing between the first cell and the second cell;

    determining a timing offset representative of a sub-frame delay between the first cell and the second cell;

    selectively updating the sub-frame pairing based on the timing offset by aligning a first downlink discontinuous reception (DRX) pattern of the first cell with a second DRX pattern of the second cell based on the sub-frame pairing;

    transmitting timing information of the first and second DRX patterns to the UE; and

    signaling the first cell and the second cell of the DRX patterns and corresponding timings.
