Abstract
Aspects of the present disclosure provided techniques that may be applied in systems that utilize bundled transmissions from a base station (e.g. an eNodeB) to a user equipment (UE) when a user equipment (UE) is in a connected mode of operation. An exemplary method performed by a UE for processing a downlink control channel sent as a bundled transmission over a bundle of subframes comprises determining when to start monitoring for the control channel; and monitoring for the control channel in a limited number of downlink subframes based on the determination.
