Abstract
Methods and apparatus are disclosed that facilitate discontinuous reception via a primary cell and one or more secondary cells that have different TDD UL/DL subframe configurations including overlapping subframes, such as in an instance in which a UL subframe of a secondary cell overlaps with a corresponding DL subframe of the primary cell. A method may define an active state of a primary cell to be larger than an active state of a secondary cell in a TDD network that supports carrier aggregation. The method may also provide for discontinuous reception via the primary cell and the secondary cell in accordance with different TDD UL/DL subframe configurations and also in accordance with the respective active states of the primary and secondary cells.
